Description

Corner type pressurizing device for attaching cargo hold sheet {CORNER TYPE PRESSING APPARATUS FOR SHEET BONDING IN CARGO}

The present invention relates to a corner pressing device for attaching cargo hold sheets used in the manufacture of ships and cargo holds thereof.

In general, ships such as LENG carriers are provided with insulation to maintain a temperature of minus 163 degrees within the cargo hold corresponding to the cargo (cargo).

Cargo holds may be constructed in a polygonal structure, and each corner shall have a frame (eg corner holder, etc.) shaped to correspond to the specification angle, specifications, etc. of the technical specification.

For example, the corner portion of the cargo hold is formed by any of standard angles of 90 degrees, 108 degrees, 135 degrees, and 162 degrees.

The cargo hold is constructed with a corrugation-shaped membrane corresponding to the primary barrier, the sheet and the insulation corresponding to the secondary barrier as core materials of the cargo hold system.

Insulation materials for cargo hold construction include a corner panel, a hard wood key assembly 1 (see Fig. 1). The hardwood key assembly is installed on the corner panel and has an anchor base and an anchor bolt, and is prepared for each of the standard angles and installed at the corresponding corner portion of the cargo hold.

Then, a sheet such as a triplex is attached using an adhesive and pressing jig, such as epoxy glue or PU glue, based on the corner of the corner panel. The corner portion of the corner panel corresponds to the seating work area 2 (see Fig. 1) as the joint portion between the corner portions of the corner panel corresponding to the lower part of the empty space between the hardwood key assemblies and its surroundings.

However, since the bending of the hull inevitably occurs in the cargo hold manufacturing process, the installation state of the corner panel and the like on the hull has a great influence on the sheet adhesion quality.

Although the level pad is attached after measuring the deformation amount to correct the deflection of the hull and the like for maintaining the sheet attachment quality, the level pad measurement is low, and it is difficult to completely correct the angle difference between the walls and the like. It is true that these causes have a large impact on subsequent processes. Due to such a cause, a step may occur between the corner panels to cause a difference in the applied adhesive, or the height and angle of corner portions of the corner panels may be different.

In addition, in the process of installing the corner panel, excessive force is applied to the corner panel to match the step, etc., which may cause deformation, and the sheet may be peeled off from the corner panel, which greatly affects the adhesion quality.

In addition, the deformation caused by the movement of the ship, the curing process of the resin adhesive for attaching the insulating material affects the installation state of the corner panel.

As shown in Fig. 1, the corner pressing jig 4 according to the prior art is a corner panel which is a seat attachment working area 2 formed between the hardwood key assembly 1, which may be referred to as the corner of the cargo hold. After the adhesive is applied to the corner portion, the sheet 3 is temporarily bonded to the adhesive using a tool such as a manual roller, and then used. The sheet 3 is pressed at a predetermined pressure and cured at a predetermined temperature. It refers to a jig assembly.

Corner pressing jig (4) is a plurality of components are separately separated and installed sequentially each time the sheet attaching operation, the components to be separated again after the operation, such as the pressing plate (5), air pressing board (6) (air pressing board) ) Or an air matrix, an angled outer wedge 7 (wooden wedge), two mounting angles 8, a correction support 9.

On the upper surface of the sheet 3, a pressing plate 5 having a heater or a rubber plate or the like is placed thereon, and an air pressing board 6 or the like is placed thereon.

In addition, an outer fixing part 7 is placed on the air pressing board 6, and two mounting angles 8 are arranged to press the outer fixing part 7, and ends of each of the mounting angles 8 are provided. Is coupled using mounting means such as anchor bases and anchor bolts of both hardwood key assemblies 1.

In particular, the operator is used purely depending on the operator's sense even in the use of the support 9 for correction.

In this state, after supplying air to the air pressing board 6, curing the adhesive for 11 to 12 hours, pressurizing for 24 hours at a constant pressure of the air pressing board 6, the sheet 3 Is attached to and adhered to the corner portion of the corner panel, which is the sheet attachment work area (2).

However, the corner pressing jig according to the prior art is very inconvenient to use because it is necessary to combine or disassemble the air pressing board, the outer fixing part, the two mounting angles, and the correction support sequentially on the pressing plate whenever the work is required. According to the skill of the operator and the installation state of the corner panel, there is a disadvantage in that different sheet attachment quality appears.

In addition, the pressing jig for corners according to the prior art must accurately match the position between the air pressing board, the outer fixing portion, the two mounting angles, and the support for correction on the pressing plate in order to uniformly provide the pressure of the air pressing board. Installation is cumbersome and inconvenient to use.

In addition, the pressing jig for corners according to the prior art is different from the material of the air pressing board (e.g. synthetic resin), the material of the outer fixing part (e.g. wood), and the installation angle (e.g. metal) are connected to each other. It is very difficult to do, and even if they are connected, there is a fear that breakage or destruction due to the release material may occur at the connection point due to the pressure action of the air pressing board.

In addition, the outer fixing portion of the pressing jig for corners according to the prior art is made of a wood material and plate-like structure has a disadvantage in that durability and structural rigidity is relatively inferior.

In particular, the conventional outer fixing part is smoothly corresponding to the corner part of the corner panel, and has an upper side and a lower bottom surface for pressing and covering the entire sheet attaching work area all at once, so that the misalignment, step, gap, irregularities, It has a disadvantage in that it does not correspond closely to the corner portion of the sheet attachment working area in actual field situations such as geometric surface shapes such as convex, concave, inclination, and the like.

In addition, since the pressing jig for corners according to the prior art is largely dependent on the skill of the operator in the installation of the outer fixing portion and the air pressing board, poor adhesion quality occurs frequently.

For example, the pressing plate and the outer fixing portion and the installation angle are separated, so that the operator must hold the pressing plate while the air is introduced into the air pressing board, and the position must be aligned. In particular, when the corner portion of the pressing plate is not exactly positioned at the corner portion of the corner panel, the pressing plate finds its position due to the pressure of air injected into the air pressing board. It may cause a malfunction.

In addition, the pressing jig for corner according to the prior art is almost impossible to press the bent or protruding part of the corner only by the air pressing board, so a separate correction support must be used, which is also fully pressurized according to the skill of the operator. Will be different.

In addition, the corner pressing jig according to the prior art is more time-consuming since additional work, such as connecting the hose for air injection for the air pressing board, hose line treatment, etc., is relatively time-consuming, and the hose itself is an obstacle at the work site. It is working. For example, since the air pressing board is a type of air bag, it is difficult to know the direction in which the air is pressurized first when the air is introduced, and it is not easy to control and use, and there is an inconvenience of having to install an air injection line to be connected to the air pressing board every time the jig is installed. .

Therefore, the present invention has been made in order to solve the problems of the prior art as described above, by coupling a plurality of pressing plates to the pressing portion of the balancing link cutting method, and then by pressing with a screw fastener capable of adjusting the torque amount, Corresponding to the corner portion of the corner panel having a geometric surface shape, the sheet can be closely adhered to, the attachment work can be facilitated, and the corner type pressing device for attaching the cargo hold sheet which can ensure a uniform adhesive quality is provided. Make it a technical task.

An object of the present invention as described above, as described in detail below, in the corner type pressing device for cargo hold sheet for pressing the sheet in the corner portion of the corner panel provided in the cargo hold, the area of the corner portion of the corner panel, A pressing plate having a relatively narrow area and plate shape and provided in plural to provide partial surface pressure at a plurality of points; A pressing unit in which the pressing plate is coupled in a balancing linkage manner through mechanical joint means; Screw tightening unit for individually providing a pressing force to each of the pressing portion through the screw rotation; An angle part for supporting a repulsion force against a pressing force generated by the operation of the screw tightening part; It is achieved by a corner type pressing device for attaching the cargo hold sheet characterized in that it comprises a frame portion of the skeleton structure for supporting the angle portion and the screw tightening portion.

Therefore, the present invention provides a corner pressurizing device for attaching a cargo hold sheet incorporating a plurality of pressing plates, a pressing portion of a balancing link section method, a screw tightening portion capable of adjusting torque, and a frame portion, thereby simplifying movement, storage and use. In addition, it is possible to solve the inconvenience of the existing corner pressing fixture that must deal with several components at the same time, there is an advantage that can eliminate the additional work according to the use of the existing air pressing board.

In addition, the corner type pressing device for attaching the cargo hold sheet of the present invention is to press the pressing plate which can be individually moved as a plurality through a balancing link section type pressing unit, such as a step, a gap, an unevenness, a convex shape, and a concave shape. ), Airtight, precise and three-dimensional surface pressure in the corners of the corner panel having a geometric surface shape, such as inclination, there is an advantage to ensure a uniform adhesive quality.

In addition, according to the present invention, the corner pressurizing device for attaching the cargo hold seat has a frame portion of a minimum skeletal structure that can withstand the pressure applied, so that the weight is relatively minimized, even though it is a metal material, and a conventional press plate may be used as it is. There is no need for additional press plate changes.

In addition, the corner type pressing device for attaching the cargo hold seat of the present invention enables the use of a torque amount adjustment tool such as a torque wrench, etc., so that an inexperienced person can easily and collectively perform the work.

In addition, the corner type pressing device for attaching the cargo hold seat of the present invention matches the corner screw tightening portion with the center reference line CL among the plurality of screw tightening portions, while the upper corner screw tightening portion disposed around the corner screw tightening portion. Alternatively, as the corner right screw fasteners are arranged to be eccentric to the center reference line, the bolt heads of the fastening bolts do not interfere with each other when the fastening bolts of each of the corresponding screw fasteners are lifted up, so that the torque amount adjustment tool There is an advantage in that it is possible to perform a fast bolt tightening or loosening operation while facilitating the use.

In addition, the corner type pressing device for attaching the cargo hold seat of the present invention has the advantage that the effective pressing operation can be realized by moving the pressing unit linearly with the help of a guide when tightening or loosening the tightening bolt of the screw tightening unit.
