DEPARTMENT STORE

The invention relates to a glasshouse comprising a roof supported by uprights which comprises at least two substantially parallel, longitudinally extending cams and a gutter lying between them, rods being arranged between the cam and the gutter. A calf is preferably arranged in the longitudinal direction between two rods and the roof has roof elements such as windows or other transparent elements.

Such a department store is known. A problem occurring at the known department stores is the condensation on the roof elements. Part of the condensate is drained to the gutter.

The invention has for its object to improve the known department store, and in particular to improve the condensation discharge. The condensation drips along parts of the roof structure and thereby falls on the goods present in the department store, which leads to damage.

An improved department store according to a first aspect of the invention is obtained in that the rod and the calf are arranged for condensation discharge and a discharge of the calf leads to the rod. As a result, a department store is obtained in which a condensation discharge is formed, wherein condensation is led from the calf to the rod for discharge. The condensation that forms at the calf or that can be collected by the calf is discharged to the rod, the rod preferably draining the condensation further, preferably in the gutter, preferably in a condensation collecting channel arranged in the gutter.

A further embodiment of the invention preferably comprises a calf that has a condensation channel and a rod that has a condensation channel, wherein the condensation channel of 03/0356 «2 has a drain that connects to the condensation channel of the rod. A department store according to the invention has a calf and rod that have at least two channel-shaped parts that connect to each other for the condensation drain.

The calf is preferably connected by means of an open connection to the rod for the condensation discharge. The condensation drain in the calf flows into the condensation drain in the rod.

According to a further embodiment, a mouth 10 is formed between the calf and a roof element adjoining it, the mouth being formed for collecting condensation from that roof element. Condensation can form on the roof element and be guided along the roof element. Department stores preferably have sloping roofs that extend from the ridge down to the gutter. The calf is arranged in the longitudinal direction between the ridge and the gutter and therefore condensation will collect from the roof element which is situated between the ridge and the calf. On that side the calf is provided with a mouth in which the condensation can be collected. The mouth has an open connection with the condensate discharge channel formed in the calf, which channel has an open connection with the condensation discharge channel of the rod. The calf can be provided with a part extending parallel to the roof element in the direction of the ridge and remote from the roof element, such as a flange for condensation collection.

In a preferred embodiment, the calf is formed with a U-shaped cross-section and the inside of the U-shape forms the condensate drain. A calf can be obtained, for example, by extrusion with the said cross-section. In another embodiment, the calf is formed as a rolled steel profile, optionally provided with a coating. This particularly simple embodiment leads to a high stiffness due to the use of steel and, therefore, the calf can be of small dimensions and yet have the same stiffness as aluminum profiles.

Preferably the rod has an opening and an end of the calf is received in the opening of that rod.

As a result, condensation guided in the calf can be fed into the rod. The condensation channel leads through the opening to the interior of the rod where the condensation drain channel of the rod is located.

It is preferable to partially cut out the calf at least at one end. As a result, a part of the calf can be received in the openings, and at the same time the opening forms the place of attachment of the calf to the rod. A particularly simple construction is hereby obtained.

It is furthermore preferred to design the calf as a hollow profile that can be coupled to engaging means for the roof element. The hollow profile, preferably rolled steel, has a longitudinal opening which can be engaged by the gripping means for the roof element, for example a flexible strip which can be coupled to the roof elements, preferably the edge of a window.

It is furthermore advantageous that the calf borders on a skylight incorporated in the roof and that an engaging means for a roof element is also support means for the skylight incorporated in the roof. The skylight has, for example, a hinge, which is preferably connected to the ridge of the department store. By opening the skylight, fresh air can enter the department store. The free end, i.e. the end of the skylight removed from the hinge, can rest on the flexible engaging means. A closure of the skylight is hereby obtained.

The engaging means preferably has an S-shaped cross-section, which forms a receiving space for an edge of a roof element such as a window. The engaging means can be formed as an extrusion profile, for example from plastic.

Preferably, an upper side of the S-shaped profile is the contact surface of the free end of the hinged skylight.

It is further preferred that the engaging means has a lip extending over a part of the length of the calf, which is part of the contact surface, and which is adapted to drain the condensate into the calf. The lip connects to the skylight, and condensation that forms on the inside of the skylight flows in a closed position of the skylight towards the calf and is led from the skylight via the lip in the calf's mouth preferably to the interior of the calf where the condensation is drained through the channel.

It is furthermore advantageous for the lip and a longitudinal edge of the calf to form the mouth for supplying the condensate to the calf. This is a particularly simple construction that leads to improved condensation collection and discharge.

It is furthermore advantageous that the rod has a hollow profile and that it is designed as condensation drain. The rod preferably has an end which is coupled to the gutter and that end preferably forms the discharge of the condensation discharge channel from the rod, and that end and the gutter are arranged such that condensation discharge takes place from the rod in the gutter, at preferably in the condensation drain of the gutter.

The invention also relates to a method in which a roof is formed for a department store. The method comprises providing gutters, cams, rods and calf for forming a roof. According to the method, the various parts are connected to each other, so that the roof is formed. The rods are placed between ridge and gutter and connected to each other. A calf is placed between two rods. According to the invention, an end of a calf is preferably received in an opening, preferably in a side wall, of the rod. As a result, the calf 5 can be easily connected to the rod and the calf has a fixed position with respect to the rod.

According to the invention, the opening in the rod can be formed by punching an opening in a steel plate, from which the rod is rolled. Because the rod is a steel rod that has been rolled, the rod can be manufactured at low costs. The advantage of a rolled rod is that openings can be formed before the rod acquires its final shape through rolling. Die-cutting can take place before rolling. An opening of any shape can hereby be formed in the rod. The random shape can correspond to the cross-section of the formed calf. The calf can also be rolled. The cross-section of the calf corresponds to the opening in the side wall of the rod, whereby the calf is steadily received in the opening, whereby the opening also fixes the calf. The opening corresponding to the cross-section of the calf is a receiving chamber which limits a number of degrees of freedom of the calf.

In contrast to extruded profiles, such as aluminum profiles, the opening in the rod can have an arbitrary shape when it is formed by punching before rolling the rod. With extrusion profiles, only a round borehole could be formed. The punching makes a random opening possible.

In a preferred embodiment, the calf is also formed from steel and obtained by rolling. In a preferred embodiment, one end of the calf is cut out. The cutting out can take place before rolling.

6

As a result, the end of the calf has only a part of the cross-section of the total calf and only that part is included in the side wall of the rod.

By rolling it is possible to obtain a calf which is partly formed from steel and wherein the calf further comprises a strip which can be placed on the calf. The strip is, for example, formed for engaging the roof elements, such as the windows. A cold bridge is hereby also obtained. The cold bridge insulates the cold windows of the "warm calf", thereby reducing the condensation on the calf.

The connection of calf and rod, in which the calf end is included in the rod, allows condensation transport to be made. Condensation can be collected in the calf and guided through the opening from the interior of the calf to the interior of the rod. This will be further described in the figure description.

Although the invention is described with reference to the preferred embodiment, it will be clear that various other embodiments are possible within the scope of the claims. The skilled person will be able to vary within the scope of the claims. Although the invention is described on the basis of the exemplary embodiments and on the basis of measures which are enumerated in combination, it will be clear to the skilled person that the measures mentioned in this description can be freely combined with each other and that it is possible to submit a hive-off in a combination of these measures.

The invention will be further described with reference to the preferred embodiments shown in the drawings, wherein:

Figure 1 shows a perspective view of a department store according to a first embodiment; 7

Figure 2 shows a cross-section of a gutter according to arrow II in Figure 1;

Figure 3 is a perspective view of a detail of a roof of a department store according to a first embodiment;

Figure 4 shows a second perspective and cut-away view of a detail of a roof of a department store according to a first embodiment.

The greenhouse 1 shown in figure 1 shows a roof part 2 which is supported by uprights 3. The department store 1 is known, for example, from NL-1030448 in the name of the same applicant, which by reference forms part of this description. The person skilled in the art will be able to extract additional information from this patent application 15 in the following description. The structure of the department store 1 is described below as necessary for understanding this invention.

The roof 2 comprises a number of parallel projections 4 and gutters 5 lying between them. The projections and gutters extend in a longitudinal direction 9. Between each projection and an adjacent gutter 5, rods 6 extend, whereby between the rods, projection and gutter plate-shaped elements such as a pane 7 are placed. The cam, rod and gutter are provided with engaging elements, in this case receiving elements 25 for an edge of such a window. These will be described in further detail below. The edges of the window are received in the respective receiving elements.

A roof window 40 can be included in the roof 2. The skylight is hingedly connected to the cam 4 and can be swiveled open according to arrow 41. A calf 42 is arranged in some places between the rods 6. The calf extends in a longitudinal direction 9. Preferably, the calf 8 is part of the skylight 40. In the closed position, the window 40 rests on the calf 42.

According to another embodiment (not shown) the roof is provided with a foil roof element. The gripping means / clamping means for the roof element are then adapted to the foil. The construction of the roof can then, for example, be carried out with fewer rods.

In the department store 1 according to the embodiment of figure 1, uprights 3 are connected in a direction transverse to the gutter direction 10 by girders 8. The girders 8 together with the gutter 5 form the bearing construction of the roof 2.

The gutters extend in a longitudinal direction, indicated by arrow 9 of the greenhouse and the girders extend in a transverse direction.

At the end of the cams 4, the greenhouse is closed with a wall 10 that is shown partially cut away. On the roof 2, the rainwater collects in the gutter 5 and is discharged therefrom near the facade 10 via a collecting tank 11 which connects to a rain pipe 12.

Figure 2 shows a cross-section of the trough 5, the rod 6 also being shown. The assembly of the gutter 5 comprises a gutter profile 13 which in the embodiment shown is a closed box profile. In a preferred embodiment it is a rolled steel gutter profile, but also an aluminum gutter profile is possible. The gutter profile 13 can be rolled and the ends of the gutter profile can be connected to each other, for example by welding, cold forming, seaming and the like. When working with a steel profile, a number of recesses can be provided for rolling in the steel strip, which recesses become part of the profile. This will be discussed later.

9

The trough profile 13 has a condensation water drain 14 and a rainwater drain 15. Rainwater will flow from the roof into the gutter via arrow 16, while condensation water can end up in the condensation drain 14 according to arrow 17. Condensed water 14 is located on the inside of the shaped greenhouse and can pass through a recess 45 in a wall part 18 of gutter profile 13 into the inner, condensate drain 14, of the gutter.

A gutter strip 21 is attached to an upright wall 22 of gutter profile 13 by means of bolts 20. The gutter strip 21 is preferably an aluminum gutter profile formed by extrusion. The gutter profile has a substantially T-shaped cross-section as shown in figure 2. The gutter profile 21 lies in the mounted state as shown in figure 2 with one leg of the T over the upper edge 23 of gutter profile 13.

Extrusion profile 21 is provided with recesses which are arranged at the same distance as recesses which are arranged in predetermined places in gutter profile 13.

As a result, a trough profile 21 can in each case be connected to the trough with bolts 20 at fixed locations.

In the transverse direction, in the mounted state of the gutter strip 21, an edge 24 protrudes which is provided with a. hooking part 25 with an edge 26. Condensed water that forms on the inside of the panes 7 can be diverted via the hook 25 and edge 26 according to arrow 27 to the condensation drain 14.

An edge 30 of the pane 7 is supported on projecting part 24 of the gutter strip 21. A pane 7 arranged on the projecting part 24 can be confined by arranging a second part 31 of the gutter strip. The second part 31 is preferably a PVC gutter strip. The first gutter strip part 21 and second gutter strip part 31 have an interlocking system 32 which is shown in the shown embodiment by hooking parts. By applying PVC strip 31 to the gutter strip 21, the edge 30 of the window is enclosed.

Condensate is led via the underside of the windows or the rod according to arrow 27. When the condensation is led through the window, that condensation will flow against hook 25 / end 26. This hook / this end will guide the condensate to the condensate trap according to arrow 17 by gravity. The condensate is led away from the upright wall part 22 of the gutter, directly to the condensation channel.

Gutter 13 has a condensation collection section, generally indicated by 109. This is a part of the gutter, which is inclined towards the rod, in the mounted state, formed by rolling the gutter material. The end of the condensation collection portion near the rod end, roughly indicated by 110, is rounded. The end of that edge of the gutter does not support the rod. This rounding is favorable for the discharge of condensation drops which form on the underside of the rod 33. The drops can now be guided along the underside of the rod 33 in the condensation collector 20 according to arrow 17. The gutter edge 110 does not prevent transport of the drops from the bottom. Drop formation near the transition rod to gutter is prevented, which also prevents damage to crops in the greenhouse because drops falling from the gutter fall down.

Rod 6 consists of an aluminum rod part 33 and a PVC top piece 34 that is attached to the aluminum part by means of an interlocking system 35. The PVC part 34 has two receiving chambers 36 as shown in Figure 3 in which edges 30 of the window 7 can be received.

As can be seen in figure 3, the rod 6 is hollow and has an inner space 50. This inner space is arranged according to the invention and used as an additional condensate drain.

The rod abuts the gutter as shown in figure 2. Condensate that is collected in the inner space 50 can flow out of the end 51 of the rod and thereby flows into the condensation collecting part 109 of the gutter and can flow through according to arrow 52 to the condensation collection chamber 14 in the interior of the trough via the opening 45. The rod 6 has a condensation discharge opening near the end 51 which is in open communication with the condensation discharge 14 of the trough 5.

Figure 3 also shows a calf 42. The calf 42 has a U-shaped cross section. The calf 42 can be formed by extrusion, for example from aluminum. In the preferred embodiment, the calf 42 has a steel rolled profile.

The calf 42 has a U-shaped cross-section with two flanges 60, 61 pointing outwards. The flanges have two different functions in the embodiment shown.

Flange 61 is engaged by a flexible strip with a partially S-20 cross-section. The flexible strip forms an insulation. Due to the flexible strip, the calf is isolated from cold parts, such as the window 7. The strip 62 forms a cold bridge. The S-shape is suitable for receiving the flange 61 and an edge of a roof element such as a window 7. The strip 62 grips clampingly on the flange 61. Additional clamping means or other fastening means can be provided for mounting the strip on the calf 42.

The strip 62 furthermore has a partially dome-shaped upper part 65, which also forms an abutment surface for a hinged skylight window 66 which is formed, for example, from tempered glass. Figure 3 shows the skylight in the closed position, with the hardened glass abutting the strip. Use can be made of raised strips that improve the seal between strip 62 and skylight 66.

The strip 62 further has a lip 68, which lies along the longitudinal direction of the skylight 66 and which tapers in a point directed away from the strip. The lip 68 is formed as a conductor of condensation drops forming on a bottom side of the skylight 66.

A mouth is formed between the lip 68 and the calf flange 60. The mouth 69 is an opening that connects the space under the skylight with the interior of the calf, which is designed as a condensation drain.

Flange 60 protrudes in the direction of the cam not shown in Figure 3. The flange thereby runs somewhat parallel to the closed skylight. The flange 60 protrudes in the transverse direction.

Condensation can form on the underside of the skylight 66. The condensation 70 can be guided in the direction of the calf 42 under the influence of gravity on the underside of the skylight in the direction of arrow 71. Near the calf 20 the lip 68 guides the drops from the window and into the mouth 69 into the U-shaped profile of the calf 42.

The interior of the calf forms a condensation collection channel 80.

Figure 4 shows a detail of the roof 2. Calf 42 is shown. The strip 62 is placed on the flange 61. Mouth 69 is again shown for clarification. The mouth 69 is formed between lip 68 and flange 60.

The calf 42 is connected to the rod 6. The rod is provided with an opening 82 in a side wall of the rod. The opening can be formed before the rod is rolled to the final shape. As a result, such an opening can be formed at low costs.

13

The opening 82 can be formed by punching before the rod is rolled from a steel plate. Punching makes it possible to form an opening with a suitable shape. The shape of the opening substantially corresponds to at least part of the cross-section of the calf. In the embodiment shown, the calf 42 is partially cut out. The cross-section of the end 84 of the calf 42 corresponds to the formed opening 82 in the side wall of the rod.

The end 84 of the calf 42 has been partially cut out.

As a result, the calf 42 has an end 85 which is substantially trapezoidal in this embodiment and which can be received in the opening 82, which is also trapezoidal.

In addition, the connection is advantageous for the discharge of condensation. Condensation caught in the channel 80 via the mouth 69 can leave the calf 42 via the end 85 received in the rod and is thereby caught in the hollow interior 50 of the rod 6. The rod is placed obliquely between the ridge and the gutter and the condensate will therefore flow downwards towards the gutter and there be discharged there according to arrow 52 into the condensate collection in the gutter.

The greenhouse according to the invention thus provides for the additional condensation drain of roof elements that are located above the calf. The discharge conducts the condensate via the interior of the calf to the interior of the rod and ultimately to the condensation collection of the gutter.

In another embodiment, the calf is provided with a channel part for collecting condensation which is formed on an outside of the calf, for example a channel part that is comparable in shape to the condensation collection part 109 of the gutter. Via that channel the condensation can be led to the rod and there be collected internally or also in a channel 14 on the outside of the calf and further discharged to the gutter.

The invention provides the possibility of additional condensation collection and removal. This reduces the damage caused by falling condensation drops to the goods grown in the department store.

It will be apparent to those skilled in the art that various other embodiments are possible within the scope of the claims.
