Description

Packaging and / or transport unit for plate-shaped insulating elements

The invention relates to a packaging and / or transport unit for plate-shaped insulation elements, in particular large-sized roof insulation panels, preferably of mineral fibers, especially rock wool, consisting of a support element, preferably two spaced-apart support bodies and arranged on the support element plate stack of individual insulating elements , wherein the support element is connected to the plate stack in particular by a film which surrounds at least the panel stack at least part of the area. Furthermore, the invention relates to a cargo for a transport vehicle, namely for a truck or trailer, consisting of at least two such stacked packaging and / or transport units.

Load-bearing roof shells of, for example, hall-like buildings are made of profiled sheets, which are referred to as trapezoidal sheets and joined together to roof surfaces. The roof areas can cover several thousand square meters and are often subdivided by skylights, drainage systems, fans, air conditioning units, etc. The supporting profiled sheets are made of flat steel with thicknesses of 0.8, 1 or 1.25 mm. By a corresponding shaping, ie training relatively large heights, by beads in the straps and tilting of flanks resistance moments of the profiled sheets are increased in order to stretch as far as possible, whereby the structural design of a substructure can be reduced below the profiled sheets. The profiled sheets can have a permissible deflection of 1/300 of their span. The adjacent arranged profiled sheets are connected in overlapping areas by screws or rivets. Such roof shells are to be designed for permissible loads in the area of approximately 1.50 - 2 kN / m ² . At higher puncture stresses, the profiled sheets tend to fold and tear easily at the joints, especially as the deformability is large transverse to the clamping direction. Thus, supporting roof shells are made of profiled surfaces deformable and susceptible to wind stress. Profiled sheets are therefore rarely formed without further substructures or never to form a supporting roof shell for used roofs, such as parking decks, terraces or the like.

Profiled sheets have top chords, which have different widths. The sometimes large clear distances between the upper chords of the profiled sheets require increased attention when walking on the roof surface. The clearances vary with the most common profiled sheets between 60 mm and 170 mm. In order to be able to travel from these profiled sheet roofs with pallet trucks, sack trucks, handcart or the like, at least in the construction phase transport paths with the help of planks or plates, for example made of wood-based materials on the roof surface.

Insulating layers are laid out on the load-bearing roof shell in order to limit both the transmission heat losses, to achieve a sufficient level of airborne noise protection and, last but not least, to prevent the spread of fire across the roof surface. Nowadays mostly large-sized rockwool roof insulation boards are used, which have a melting point according to DIN 4102 Part 17> 1.000 ⁰ C. Accordingly, also slag wool or those fiber insulation materials are attributed to the rock wool insulation materials that are produced by the process techniques of glass wool production.

Conventional insulation boards for a variety of applications have dimensions of approximately 1 mx 0.6 m and are packed in individual packages delivered to construction sites. Roof insulation panels may have a large shape and dimensions of 2 m in length and 1, 2 m in width. In addition, roof insulation panels with the dimensions 1, 9 mx 1, 2 m, 2 mx 1, 0 m or 2 mx 0.6 m and in special formats are known. In order to achieve sufficient compressive and bending tensile strength for walking on or driving over the insulating layer, a large fiber mass is required, which leads to gross densities of conventional roof insulation boards made of rock wool between about 130 and 170 kg / m ³ , wherein the proportion of fiber mass about 85 up to 140 kg / m ³ . The roof insulation panels show usual terialstärken between 8 to 20 cm, with roof insulation panels with material thicknesses of 12 and 14 cm have been found to be preferred.

Large-format roof insulation panels with the trade name Metac FLP 1 Duratec and the dimensions 1, 9 m long x 1, 2 m wide are offered with different material thicknesses in stacks of packaging and / or transport units of the following design:

The packaging and / or transport units thus have an insulation volume between about 2.28 m ³ and about 2.92 m ³ and a weight between about 375 kg to about 470 kg.

The height of an insulation board stack resulting from the number of roof insulation panels and their material thickness is matched to the height of the trucks used for transport with over-planned structures with transport height heights of approx. 2.70 m to approx. 2.80 m. Of the above-described insulation board stacks can be in conventional pallets with a height up to 14 cm and taking into account the movement play of forklifts two packaging and / or transport units standing one above the other in a truck on arrange, with the loading of the truck from both sides or from behind can take place.

The above-described packaging and / or transport unit comprises pallets which can be lifted with a gripper of a lift truck or other conveying means, in which the gripper is pushed transversely under the pallet to the packaging and / or transport unit of insulation stack and pallet to raise. The pallet has two or three approximately 10 cm high beams of squared lumber on which about 5 to about 7 6 to 10 cm wide and about 1, 5 cm thin cover boards are attached. Such a pallet is known for example from DE 41 13 096 A1. Instead of the joists and blocks between an upper deck board and a lower floor board may be provided, as is known from DE 83 03 910 U1. The outer deck boards are flush with the beams. The pallets described above have a dead weight of between about 12 and about 25 kg / m ³ . On the strength of the pallets, in particular the bending tensile strength only small demands are made, since the insulation boards are stiff from 8 cm in thickness. Thinner insulation boards, which are used as supplementary products, for example as refurbishment plates, have a lower flexural stiffness, but are still stacked and transported on corresponding pallets, so that the pallets deform differently depending on the resting insulation boards when lifting under load.

The packaging and / or transport unit of insulation boards and pallet further comprises a plastic film to which the insulation boards and the pallet are connected, in which placed by the stack in the top insulation board a portion of the plastic film and the stack of insulation board then in the horizontal direction is wrapped with stretch film. Protective hoods made of shrink-wrap films, which are pulled over the stack of insulation boards and then shrunk onto them by the action of heat, also provide adequate protection. The hood also partially captures the pallet so pallet and stack are connected via the hood. In addition, strapping bands made of plastic and metal are provided, with which the stack of insulation boards connected to the pallet is. In order to prevent damage to both longitudinal edges of the topmost insulation board in the stack, corner protection angles are arranged from cardboard below the strapping.

The Circular Economy Act in the form of the Packaging Ordinance stipulates that the manufacturer of the insulating materials either withdraw the packaging materials and / or introduce them into a material cycle. In applications with a high demand for insulation materials, the insulation materials are delivered directly to the construction site by the manufacturer. For the manufacturer of insulating materials, it has proven to be economical to provide packaging materials at its expense in a general construction site collection and recycling system.

In practice, the resulting packaging materials such as films, straps and pallets are collected, and filled for safe transport and an orderly storage in provided collection containers.

For the insulation of a roof area of approx. 1,000 m ² with 14 cm thick roof insulation panels, at least fifty packaging and / or transport units with pallets are required, without taking into account the resulting waste. The return of the pallet with a weight of approx. 650 kg requires a container with a volume of approx. 12 m ³ . Furthermore, the disposal of the packaging materials, in particular of roof areas, requires a considerable amount of time, which increases the costs of the roofing work, so that in view of the fierce competition, the economy of the roofing works is considerably impaired.

From DE 42 18 354 C2, a transport unit is known, which consists of a stack of large-sized insulation boards made of mineral wool, which rests on two transverse to the longitudinal extent of the insulation boards arranged support bodies. These support bodies consist of sections of the stack forming insulation boards and are 30 to 40 cm wide, the support bodies are subjected to a compression load of less than 40 kPa a maximum compression of 10%, so that overloads occur even in the case in which two transport units on - stacked each other. The support bodies have a height of at least 9 cm and are arranged in such a way under the stack that the insulation boards resting thereon are supported as a multi-field support and thus stable in itself. In practice, the insulation boards each protrude from the outer side surfaces of the support bodies.

Due to high internal friction between the insulation boards and internal vibration damping, neither the individual insulation boards nor the entire stack slip on the supports or under the loads, which softens the load under load, even on flat surfaces of flatbeds.

To protect against the weather, the insulating panels and the support body are covered with a thin stretch film, which also allows transport on open trucks, as described in DE 102 10 411 A1.

If support bodies are damaged during storage and / or transport, the damaged support bodies can be cut into narrow moldings which are clamped as bead fillers between flanks of the profiled sheets, around the insulating layer resting on the upper belts, for example in the connection areas of built-in components or along to support the Attiken. In such a use of the support body fall as waste only a small amount of films and adhesive tapes with which the films are held together complementary and labeled at the same time.

The use of the support body made of mineral wool is therefore for both the manufacturer of the insulation boards as well as the user of great advantage.

There are often several months between the manufacture of the insulation boards and their use. In order to utilize the manufacturing plants even in the low-season winter months, it is preferred to stock insulation boards with a high density. For cost reasons, open storage areas are used on which stacked up to three packaging and / or transport units become. As a result, in particular the support body made of mineral wool of the lower packaging and / or transport unit are very heavily loaded on pressure.

In addition, when storing packaging and / or transport units on open storage areas, it must be taken into account that the thin stretch films are not UV-resistant. The packaging and / or transport units are therefore preferably protected with dark colored hoods of polyolefin films. Since these water vapor-impermeable films can have a negative effect on the strength of the insulating panels, the use of hoods made of water-vapor-permeable nonwovens made of plastic fibers is already recommended in DE 198 58 201 A1.

If storage and / or transport units are stored for months on unpaved, uneven storage surfaces, the wrapping stretch films and other films are easily perforated, so that precipitation can penetrate the packaging quickly, but slowly escape. In addition, the insulation boards are often exposed to the soil moisture of the storage yard and / or the construction site. Furthermore, the support bodies are deformed by bumps, so that they are used for the installation in the insulating layer at best limited.

It is also known to connect the support body with a resting thereon insulating board, for example, to glue with a hot melt adhesive. Such a connection is to be solved on site only with considerable effort, both the insulation board as well as the support body can be damaged.

An advantageous alternative is to connect the support body made of mineral wool with the aid of films with the lowest insulation board of the stack. This compound can be solved on the construction site without effort and without damaging the insulation board and support bodies and is known from EP 0 664 257 B1. Furthermore, it is known to arrange a stack of insulation boards on two strips of polystyrene foam. The higher strength of the polystyrene rigid foam and the use of the insulation layer, which is not planned from the outset, allow the width of the support body to be reduced to about 15 to 20 cm at heights of about 10 cm. The insulation boards form multi-field beams and collar on the long sides about 25 to about 30 cm above the support body. The stack of insulating panels and the two support bodies are connected and protected by means of a wrap of shrink film. In order to secure the support body against tipping and / or slipping, narrow, in practice only about 15 mm wide straps made of plastic freely over the stack of insulation boards away connected to this, the edges of the top insulation board with edge angles of cardboard, for example to be protected. This results in significant problems of packaging and / or transport unit by oblique clamping, as well as twisting of the tension bands and a slight slipping of the support body.

The above-described palletless packaging and / or transport units can be handled gently with a lifting plate having a base plate, as described, for example, in DE 102 10 410 A1. But there are usually narrow straps or ropes without

Spreader wrapped around the packaging and / or transport unit and attached to a crane hook in order to lift it and to promote the roof surface. During this handling, the narrow straps or cables cut deeply into the underside of the lowest insulation board as well as into the side surfaces and in particular into the edges of the insulation boards resting thereon in the stack. Similarly, damage to the insulation boards in packaging and / or transport units with pallets are noted despite a spreading of the ropes or straps in the area of the side surfaces and / or the upper edges of the insulation boards.

The transport of the packaging and / or transport units from the truck to the roof surface is usually carried out with rented telescopic cranes. The telescopic cranes have only a limited range, which often does not go beyond the edge areas of the respective roof area. The respective location a telescopic crane is dependent on the accessibility for the truck and usually not changeable.

Tower cranes with a long reach are used on large-scale construction sites, supplying materials to several of the trades employed there, so that these tower cranes are only ever available for a specific trade for a short time. The packaging and / or transport units are therefore parked in a short time in an edge region of the roof surface, taking into account the carrying capacity of the profiled sheets. To avoid local overloads, it is common that these edge areas are reinforced at least by planks or pressure-compensating panels of wood-based materials to distribute the compressive force over a larger area.

Once a part of the insulation boards are laid as an insulating layer, the further transport of the insulation boards, in particular entire packaging and / or transport units, for example, with pallet truck on the already installed insulation boards. Under the insulation layer, a vapor-retarding and air-blocking layer is to be arranged, which often consists of loosely laid thin stretchable polyethylene films. The layer can not support the insulation boards. Alternatively, an aluminum-plastic composite film can be adhered to the upper chords of the profiled sheets, which is more durable compared to a polyethylene film. Overall, this procedure, especially for larger roof areas regularly leads to damage to the complete collapse of the insulation structure in the stacking and distribution channels.

The transport of the transport units known from DE 42 18 354 C2 advantageously takes place directly over any shaped profiled sheets with a device as described in EP 0 924 146 A1.

This designed as a lifting and rolling device consists essentially of two rolling means, which are rigidly connected to each other and a lever arm is rotatably mounted on this connecting element. Since the device is designed for a stack width of 120 cm, a clear distance of the rolling tel provided by 130 cm, which is arbitrarily changeable. For the transport of narrower packaging and / or transport units, a shorter connecting element can be used. Easy interchangeability of the connecting element is provided by plug-in bolts. The rolling elements are each roller sets, the rollers or rollers are made of tough plastic. The length of the roller sets is considered sufficient with approx. 1 m. As appropriate roll diameter 8 cm, called the width of the rolling agent 35 cm. For example, per roller 11 rollers are mounted on a rigid frame. The hard plastic rollers can be easily roll on the upper chords of the profile sheets and move laterally out of the rolling motion without additional steering device, so that cornering, albeit with large radii are possible.

The lever arm is designed as a U-shaped bracket, whose two ends are each bent at an obtuse angle. At the break point of the two ends of the lever arm is rotatably pushed over a shaft, which in turn is mounted twice on the connecting element.

In each case a lifting device is pushed under the protruding on the narrow sides of the support body insulating boards, wherein the longer outer part of the lever arm is pressed so far up that the two ends of the shorter lever arms are below the insulation boards. The two roller sets of the device are each positioned laterally from the stack of insulation boards. By pushing down the longer lever arms, the ends of the shorter lever arms describe an upward circular motion. This considerable shear forces are exerted on the contact points between the device and insulation boards. Since the stack of insulation boards rests on the roof surface, it can not be moved, but the two sets of rollers are pulled in the opposite direction. The resistance and stresses of the lowermost insulation board are reduced when both lifting devices are moved synchronously. Due to the sufficiently long lever arm slipping out of the short lever arms is even then safely avoided when the stack of insulation boards is bent upwards. Based on the above-described prior art, it is an object of the invention to further develop a packaging and / or transport unit and a load from such packaging and / or transport units such that an economical transport of insulating elements is simplified and material-friendly feasible.

The solution of the task is achieved in a packaging and / or transport unit in that the plate stack has a height> 1, 325 m, wherein the support element has a height <0.145 m and the plate stack together with the support element a maximum Weight of <700 kg.

To solve the problem is provided in a charge according to the invention that the stacked transport units have an overall height <3.10 m, each plate stack has a height> 1, 325 m and each support element has a height <0.145 m.

The embodiment of the load according to the invention or the packaging and / or transport unit according to the invention for plate-shaped insulating elements has the advantage that these packaging and / or transport units can be assembled into cargoes that can be transported in a variety of different sized vehicles in an economical manner , so that the loading volume of the vehicles can be used as fully as possible.

According to a further feature of the invention, it is provided that the stack of plates together with the support element has an overall height <1.55 m, so that with two stacked packaging and / or transport units an overall height between 2.94 m and less than 3.10 m results.

An embodiment of the invention provides that the plate stack of several, preferably 11 or 12 insulating elements with identical matching Material strength exists. Such a configuration is advantageous in terms of the logistics of handling such packaging and / or transport units by the manufacturer, but also on the construction site, since the packaging and / or transport units exclusively contain identical insulating elements, so that by a clear identification of the packaging - And / or transport units rapid allocation of packaging and / or transport units to the various trades can be done.

Preferably, the plate stack has a sufficient compressive strength in order to place another plate stack with a further support element on a topmost insulating element. This embodiment allows both a simplified transport of the packaging and / or transport units under the fullest possible utilization of the possible transport volume of a truck, as well as the space-saving storage of packaging and / or transport units on the site.

According to a further feature of the invention, it is provided that the plate stack consists of eleven or twelve mineral fiber insulating panels with a material thickness of 12 cm. According to a development of the invention it is further provided that the support element consists of two mutually spaced and substantially mutually parallel support bodies made of matching with the material of the insulating material for insulation purposes whose material thickness is identical to the material thickness of the insulating elements substantially identical. This makes it possible to process the support body made of insulating material site side in conjunction with the insulating elements, in particular the insulation boards.

The charge according to the invention is further developed in that the transport units have different heights and are marked differently depending on their arrangement on the truck or trailer. Thus, a simplified allocation of the packaging and / or transport units to the vehicles having different loading volumes, namely lorries and trailers, is possible without any problems, without gene height differences, which may not be readily apparent, a faulty loading is caused.

Finally, it is provided according to a further feature of the invention that the packaging and / or transport units are arranged depending on their arrangement on the truck or the trailer in differently colored films and / or formed with different support elements. This embodiment has the advantage that rapid logistical handling of the packaging and / or transport units is made possible by visual identification.

1 shows a packaging and / or transport unit for plate-shaped insulating elements 1 is shown in side view. The packaging and / or transport unit consists of three mutually spaced and parallel support elements 2, which are double-T-shaped in cross-section and together a support element 3 for a stack of plates arranged thereon 4 of ten arranged on the support bodies 2 insulating elements 1 forms.

The support body 2 are in the embodiment of Figure 1 by way of example with different fasteners attached to the plate stack 4, wherein the left support body 2 is connected to the entire plate stack 4 and the support body 2 encompassing film strip 5 with the plate stack 4. Alternatively, the attachment of the middle support body 2 provides a foil strip 6, which connects the support body 2 with the lowest Dämmstoffele- element 1 of the plate stack 4. In addition, an edge protection angle 7 with L-shaped cross-section is placed on the insulating element 1. Of course, two edge protection angles 7 are provided in this regard, which in each case rich parallel to each other and spaced from each other arranged longitudinal edges 8 are arranged below the film strip 6.

Finally, FIG. 1 shows, with respect to the right-hand support body 2, the use of a tensioning belt 9 which connects the support body 2 to the plate stack 4, whereby edge protection angles 7 are additionally arranged in the region of longitudinal edges 8 of the uppermost insulating element 1 in the plate stack 4 Cutting the tension belt 9 in the edge regions of the uppermost in the plate stack 4 insulating element 1 to prevent.

The tension belt 9 thus surrounds the entire plate stack 4 and the support body. 2

The exact construction of the support body 2 will be described in more detail below with reference to Figures 12 to 25.

Figures 2 and 3 show further embodiments of a packaging and / or transport unit for plate-shaped insulating elements 1 with support bodies 2, wherein the insulating elements 1 are in turn combined to form a plate stack 4.

In Figure 2, ten insulating elements 1 form the plate stack 4, wherein each insulating element 1 has a thickness of 12 cm, so that the plate stack 4 has an overall height of 1, 2 m. The support bodies 2 arranged below the plate stack 4 have a maximum height of 12 cm, so that the total height of the packaging and / or transport unit shown in FIG. 2 is a maximum of 1.32 m. In the usual bulk densities of the insulating elements 1 shown here, which are used as roof insulation panels, resulting in a weight of a packaging and / or transport unit shown in the figure between 375 and 490 kg. These are large-format roof insulation panels, which are usually manufactured with an excess of 1 mm in material thickness, in order to meet the DIN EN 13162 required deviations of + 3 mm to -1 mm. With ten superimposed insulating material Elements 1 thus results in a 10 to 20 mm greater stack height of the plate stack 4, so that the actual height of the packaging and / or transport unit shown in FIG. 2 adjusts to a maximum of 1.34 m.

The packaging and / or transport unit shown in Figure 2 has insulating elements 1, the compressive strength is sufficiently high, so that at least two packaging and / or transport units can be arranged one above the other, without the insulating elements 1 of the lower packaging and / or transport units be subjected to a compressive stress causing damage. The packing and / or transport units are put together to load trucks. The packing and / or transport units are placed on überplante platforms of such trucks from the longitudinal side or from the back of the truck. In these trucks, it is known that the cargo space above the bunk is limited by the over-planning to 2.70 m to 2.80 m. Thus, two of the above-described packaging and / or transport units can be transported one above the other, resulting in a total cargo height of 2.68 m. With a cargo hold height of 2.80 m, 16 cm of height remain unused.

Insulation elements 1 represent a light but bulky cargo. Such insulation elements 1 can therefore be transported with so-called jumbo vehicles with correspondingly smaller wheels and lowered cargo areas. These jumbo-type vehicles have cargo hold heights from 2.93 m to about 3.12 m, whereby the trailers drawn by trucks can have a loading height of up to 3.20 m. Alternatives to these jumbo vehicles are lorries with lowered chassis and smaller wheels as well as special trailers in the form of open platform trucks, which are commonly referred to as convertible vehicles. For these vehicles, the limit of the cargo height is initially in the general height limit of vehicles with 4 m. The arrangement of the packaging and / or transport units shown in Figure 2 therefore leads to unused loading space above two stacked packaging and / or transport units remains.

The packaging and / or transport units shown in Figures 3 and 4 are particularly suitable for the trucks described above. The packaging and / or transport units according to FIG. 3 have a larger number of insulating elements 1, so that for the packaging and / or transport unit shown on the right in FIG. 3 with twelve insulating material elements 1 each having a thickness of 12 cm of the plate stack 4 of 1, 44 m plus a maximum height of the support body 2 of 12 cm and thus gives a total height of the packaging and / or transport unit of 1, 56 m. Two such formed packing and / or transport units can be transported one above the other in a corresponding trailer, which by design allows a total height of the load of 3,12 m, the difference to the total loading height of 3,2 m handling the packing and transport / or transport units with a forklift during loading and unloading permits.

In contrast to this, the embodiment of the packaging and / or transport unit illustrated on the left in FIG. 3 has a number of eleven insulating elements 1 each with a material thickness of 12 cm and thus a height of the plate stack 4 of approximately 1.32 m. In addition to the support body 2, which has a maximum height of 12 cm, this results in a total height of the packaging and / or transport unit of 1, 44 m. Two such packaging and / or transport units can in turn be stacked, so that the total height of the load is 2.88 m and thus suitable for transport in the above-described special trucks with loading heights of 2.93 and 3.12 m and the Handling of the packaging and / or transport units during loading and unloading by conventional forklifts.

Not shown in the figure 3 is a film which completely surrounds the plate stack 4 of insulating elements 1 and also the support body 2 with the Plate stack 4 connects. In order to distinguish the packaging and / or transport units provided for the different means of transport, namely trucks and trailers, the films of the two packaging and / or transport units shown side by side in FIG. 3 are designed with different identifications. The identification can also be given for example in the form of a different color. Of course, it is also possible to specify the marking on different support body 2.

4 shows a support element 3 for a packaging and / or transport unit for plate-shaped insulating elements is shown in a plan view. The support element 3 has three support elements 10, which are formed of pressure-resistant material, such as wood and arranged at regular intervals and parallel to each other. On the support elements 10 six right angles to the support elements 10 extending aligned supports 11 are arranged, which also consist of a pressure-resistant material, such as wood and of which the two outer supports 11 with their outer side surfaces 12 flush with end faces 13 of the support members 10.

The supports 11 collar over the externally arranged support elements 10 such that a lifting device engage under the formed regions 14 (Figure 7) and the support element 3 together with the arranged thereon and not shown in Figure 4, a plate stack 4 forming insulating element 1 raise can.

By the number of support members 10 and the supports 11, a rigid support member 3 is formed, which is also suitable in a simple manner, a packaging and / or transport unit of insulating elements 1 form, with attached in the areas 14 straps or ropes by means of a construction - Crane is liftable.

The pads 11 are aligned parallel to each other and fixed at equal distances from each other on the support members 10. The attachment takes place for example, by an adhesive connection or by nails or screws, care being taken that the connection between the support elements 10 and the supports 11 in the course of recycling of the support elements 3 should be carried out in a simple manner. The connection between the support elements 10 and the supports 11 is therefore designed such that they sufficiently fixed during the intended use of the support member 3, after the intended use, namely after the removal of all insulating elements 1 from the plate stack 4, solved the connection in a simple manner can be.

The regions 14 have a projection width of at least 15 cm, in particular at least 25 cm.

FIGS. 5 and 6 show a further embodiment of a support element 3 which consists of two individual elements 15, 16 which can be pushed into one another. In this embodiment, two support elements 10 are arranged between two supports 11, wherein a support immediately below the plate stack 4 and a support 11 rests on the ground, for example, on a bed of a truck. The individual elements 15, 16 are formed in accordance with Figure 6 in cross section L-shaped, wherein the support 11 in each case the longer

Leg and the support member 10 forms the shorter leg. In the free ends of the supports 11 holes 17 are formed at right angles to the longitudinal axis of the supports 11, which serve to receive fasteners, such as screws or nails, not shown, with which the supports 11 are connected to the support members 10.
