Description

STRUCTRE FOR A MULI-LAYERED PLATE WITH RUBBER}

The content disclosed in the present specification relates to an acrylic panel used in a building such as a greenhouse, and more particularly, to a connecting member used between a rubber multilayer board having a certain amount of rubber powder and having improved impact resistance and a rubber multilayer board during building construction. It is about.

The light-transmitting panel is a building panel that has been rapidly increasing in the use of various buildings in recent years by creating a more comfortable interior environment while increasing aesthetic sense by transmitting sunlight into the building by maintaining transparency while preventing snow or rain. The material of is usually made of polycarbonate, and the polycarbonate is light and has excellent impact resistance as well as heat insulation, and is excellent in flexibility and processability, so it is especially used as a roof and wall structure of buildings. And the shape of the wall structure is arranged at regular intervals, and several frames connected to the pillars are supported by one or more transverse frames to form the foundation of the wall or roof, and then the light-transmitting panel is fastened to the top of the frame to construct the wall or roof structure. Make up.

The light-transmitting panel fastened on the frame is produced in a standardized length and thickness, and in order to be installed in a variable structure, a plurality of light-transmitting panels are fastened to each other to complete the roof and wall structure of the building to obtain the exterior of the building.

The permeable panel is made of PC (Polycarbonate) or PMMA (Polymethylmethacrylat) material, and the advantage of light and good permeability is the nature of the material.

These permeable panels are used in various buildings such as greenhouses and electric signboards due to the properties of lightweight and good permeable materials.

Conventionally, greenhouses have been built using glass, which has the disadvantages of not protecting buildings and users from external forces caused by natural disasters such as typhoons due to low heat ratio, low construction and maintenance costs, and low impact resistance.

In order to solve this problem, a greenhouse is constructed using a double-layer plate made of PC or PMMA, which compensates for the disadvantages of glass and has a high heat rate, low construction and maintenance costs, and is economical. It is about twice as strong.

However, such a double-layered plate also has a problem of insufficient impact resistance to withstand external forces caused by natural disasters such as typhoons and hail.

In addition, when installing a building using a light-transmitting panel, a connector for connecting the light-transmitting panel must be provided, and the connection for connecting the light-transmitting panel is a polycarbonate sheet between an aluminum bending bar and an aluminum cover, as in Utility Model Registration No. 20-0238568. It is posted as a technology for inserting and mutually attaching with a waterproof gasket, then fastening an aluminum bending bar and an aluminum cover with a bolt to mutually fasten a polycarbonate sheet to form a roof of a building.

However, Utility Model Registration No. 20-0238568 has the effect of interconnecting the light-transmitting panels, but the polycarbonate sheet is placed between the aluminum bending bar and the aluminum cover to connect the light-transmitting panels, and many members such as waterproof gaskets and bolts are consumed and installed. There is a disadvantage in that the unit cost is high and the working time is long, which requires a lot of time and manpower to install, as well as a lot of hassle in dismantling and reinstalling the installed polycarbonate.

In addition, the structure is not rigid because it cannot fix the edge end of the building where the connector is not formed, that is, near the corner. In order to complete the building, a large number of connecting members are required, which is difficult to install and difficult to install. There is a disadvantage that the accessibility of the general public is blocked.

In addition, terms to be described later are terms defined in consideration of functions in an embodiment of the present invention, which may vary according to a user's or operator's intention or practice. Therefore, the definition should be made based on the contents throughout this specification.

As disclosed in FIG. 1, a rubber multilayer plate 100 structure including a rubber multilayer plate 100 containing rubber and a connecting member 300 connecting a plurality of rubber multilayer plates 100 is provided. will be.

The rubber multilayer board 100 may be generally produced by mixing rubber powder in an acrylic multilayer board used in the greenhouse 1 or the like in a weight ratio of 15 to 25, but is preferably produced by mixing in a weight ratio of 20.

This is a conclusion derived from experimental conclusions that showed the most impact resistance when mixed in a weight ratio of 20.

More specifically, as shown in Table 1 below,

[Ball Drop Test] Grade # 1 (OP side) #2 # 3 #4 # 5 (DR side) General acrylic double layer board 20 cm 20 cm 20 cm 15 cm 20 cm Rubber double layer 100 cm or more 100 cm or more 80 cm 100 cm or more 100 cm or more

A ball drop test with a ball weight of 130 (g) was applied to the general acrylic multilayer board and rubber multilayer board (100) having a thickness of 10 (mm), a standard of 990 * 2000 (mm), and a weight of 2500 (g / m2). As a result,

In general, the acrylic multilayer board has a maximum height value before crack occurs when 20 (cm) drops the ball, whereas the rubber multilayer board 100 has a maximum height value before crack occurs (100cm) ).

As shown in the above experimental results, the difference in impact resistance for each part may be different, but overall, the rubber multilayer board 100 was found to be about 4 times more resistant to impact than the general acrylic multilayer board.

The rubber multi-layer plate 100 may be formed in various shapes and sizes depending on the type of building and the purpose of use.

For example, when used for a wall of a building, it may be formed in a rectangular or square shape, and in the case of a roof, it may be formed in a circular dome shape.

In addition, the size may vary depending on the size of the building to be built.

For example, in the case of building a greenhouse, the size of the rubber multilayer board 100 used in a large greenhouse used for arboretum, etc. and the rubber multilayer board 100 used in a mini greenhouse installed in the front yard of a house are different.

That is, the size of the rubber multilayer plate 100 used in a large greenhouse is formed to have a significantly larger value than a mini greenhouse.

However, in order to lower the manufacturing cost, the size of the rubber multilayer board 100 may be standardized, and in this case, the standardized rubber multilayer board 100 may be horizontally or vertically connected using a separate frame to construct a building. Can be used to fit the size.

The method for manufacturing the rubber multilayer board 100 may be manufactured by various methods such as extrusion and injection, but the main material of the rubber multilayer board 100 is acrylic and is manufactured by extrusion in consideration of manufacturing cost and convenience in use. It is preferred.

A plurality of square grids, elliptical grids, etc. may be formed inside the rubber multilayer board 100.

However, when considering the space securing ability to fill the interior space, it is preferable that a square grid is formed inside.

As shown in FIG. 2, the inside is formed empty, but a plurality of square lattices are repeatedly formed in the space to fill the space.

Furthermore, a cross grid is formed inside the square grid, and a diagonal grid intersecting the cross grid is further formed, that is, preferably formed in a 4X-wall structure.

The external force applied to the upper surface of the rubber multilayer board 100 can be dispersed by such a structure, and thus the durability and impact resistance of the rubber multilayer board 100 are enhanced.

2 and 4, a first opening portion 203 is formed on one side of the bracket 200, and a second opening portion 205 is formed symmetrically on the opposite side.

The first opening portion 203 is one side of the rubber multilayer plate 100 is inserted and coupled, and one side of the rubber multilayer plate 100 is formed to open one side so that a space can be inserted.

The shape of the space may be formed differently depending on the shape of the rubber multilayer plate 100 to be inserted.

For example, if one side of the rubber multilayer plate 100 is formed in a circle, the space of the first opening 203 should also be formed in a circle.

However, in general, since the multi-layer plate is produced in a rectangular shape, it is preferable that the space of the first opening portion 203 is also formed to have a rectangular shape.

To this end, a support surface 210 capable of supporting the upper and lower surfaces of the multi-layer plate is symmetrically formed above and below the first opening portion 203, and seating surfaces 215 are formed at both ends of each support surface 210. Each support surface 210 is connected.

On the seating surface 215, one side of the rubber multilayer plate 100 inserted into the first opening 203 is seated to make a surface contact.

Thus, the rubber multilayer plate 100 is stably inserted into the bracket 200.

The length of the support surface 210 may be variously formed according to the application used.

For example, in the case of the rubber multilayer board 100 used for the roof, the rubber multilayer board 100 is supported by the bracket 200 in a state away from the ground, when compared to the upper surface of the rubber multilayer board 100 More load is applied.

In this case, if the length of the lower supporting surface 213 of the bracket 200 is shorter, it is difficult to withstand the load applied to the lower surface of the rubber multilayer plate 100, and thus there is a problem in that it cannot be safely supported.

That is, in order to support the rubber multilayer board 100 used for the roof, it is preferable that at least the length of the lower supporting surface 213 is formed to be equal to or longer than the length of the upper supporting surface 211.

However, in order to manufacture the brackets 200 of the support surfaces 210 having different lengths, production costs such as installing separate production lines increase, and the upper and lower supporting surfaces 211 and 213 are preferably formed in the same length. Do.

The width of the first opening portion 203 may vary depending on the thickness of the rubber multilayer plate 100 to be inserted.

However, since one side of the rubber multilayer plate 100 should be inserted into the first opening portion 203 and fixed through fitting, the width of the first opening portion 203 is inserted into the rubber multilayer plate 100. It is formed to have a value greater than the thickness, but is preferably formed to have a value corresponding to the thickness of the rubber multilayer plate 100 for interference fit.

If, if the value of the width of the first opening portion 203 is formed to have a significantly larger value than the thickness of the rubber multilayer board 100 to be inserted, the rubber multilayer board 100 may be inserted, but each support surface ( It is impossible to fix by friction caused by the contact between the inside of 210 and the two sides of the rubber multilayer plate 100, resulting in a problem of a decrease in fixing force.

Therefore, the width of the first opening portion 203 has a value greater than the thickness of the rubber multilayer plate 100 to be coupled, but when inserted, the upper and lower surfaces of the bracket 200 are respectively supported when the upper and lower surfaces of the bracket 200 are inserted. It is preferably formed to have a value that can contact the inner surface of (211,213).

As illustrated in FIG. 2, the second opening portion 205 is formed on the opposite side where the first opening portion 203 of the bracket 200 is formed, and one side of the connection member 300 to be described later can be inserted into the inner surface. A space is formed.

In addition, a hook 201 that can be coupled to the projection 310 of the connecting member 300 is formed symmetrically above and below the second opening 205.

The hook 201 is bent at a predetermined angle inward from the end of each support surface 210 of the bracket 200 to extend inward.

The bending angle of the hook 201 may be formed to have various values.

However, since the protrusion 310 of the connecting member 300 is fixed to the hook 201, it is preferably formed at an angle of less than 90 °.

If it is formed to have an angle of 90 ° or more, both protrusions 311 of the protrusions 310 cannot be caught by the hook 201, so that the connection member 300 cannot be fixed to the second opening 205. .

In addition, the shape of the hook 201 may also be variously formed, but one surface of both protrusions 311 of the protrusion 310 comes into contact with one surface of the hook 201, and the inclined directions of these surfaces are opposite to each other. As it is to be combined, the shape of the hook 201 is preferably formed to have a shape corresponding to the shape of the projection 311 of the projection 310.

The connecting member 300 includes a protrusion 310 and a central portion 320.

2 and 3, one surface of the central portion 320 of the connecting member 300 protrudes outward to form a first arc surface 321.

The length and curvature of the first arc surface 321 may be variously formed according to the intended use of the rubber multilayer plate 100.

For example, when the rubber multilayer board 100 is used for a wall of a building, the curvature value of the first arc surface 321 may have a minimum value, that is, a straight line.

This is to support the roof by forming a partition surface of a certain area in the vertical direction based on the roof in the building.

Therefore, it is not necessary for the plurality of rubber multilayer plates 100 to be combined to have a predetermined angle.

However, as shown in FIG. 2, when connecting the rubber multilayer board 101 for a roof and the rubber multilayer board 103 for a wall, the first arc surface 321 is formed to have a predetermined curvature value.

This is because, due to the structural characteristics of the building, the roof and the wall must be combined to have a certain slope.

2 and 3, the second circle having a curvature corresponding to the curvature of the first arc surface 321 on the opposite side of the portion where the first arc surface 321 of the central portion 320 is formed. The arc surface 323 is formed.

At this time, the length of the second arc surface 323 is formed to be smaller than the length of the first arc surface 321, which is to give a clearance to the connecting member 300 itself.

In more detail, the bracket 200 to which the rubber multilayer board 101 for the roof is coupled and the bracket 200 to which the rubber multilayer board 103 for the wall is coupled are coupled with a connecting member 300 therebetween. Each rubber multilayer board 100 is connected.

At this time, the rubber multilayer plate 101 for the roof formed apart from the ground is subjected to a force in the direction of gravity.

This force is also applied to the connecting member 300, the second arc surface 323 formed shorter than the length of the first arc surface 321 is bent inward by an external force. At this time, when the second arc surface 323 is bent and fixed using a finishing member or the like on the opposite side of the roof rubber laminate 101, the user can install the roof at a desired inclination angle.

To this end, the connecting member 300 is preferably formed of a material having elasticity.

If a material having no elastic force is used, the connection member 300 may be broken by the load mentioned above.

As shown in FIG. 3, the protrusions 310 are formed symmetrically on both sides of the central portion 320 of the connecting member 300, and grooves 313 are formed inwardly in the center of one surface of the protrusions 310. do.

In addition, the projection 310 is inserted into the second opening 205 and fixed.

Therefore, the size of the protrusion 310 is preferably formed to have a value corresponding to or smaller than the size of the inner space of the second opening 205.

This is to insert the projection 310 into the second opening 205.

As illustrated in FIG. 4, when the user closes both sides of the protrusion 310 by hand, the space of the groove 313 formed in the center of one surface becomes narrow, and the protrusion 311 of the protrusion 310 ) May be inserted into the second opening.

When the ridged protrusion 310 is inserted into the second opening 205 and then released, the protrusion 310 is returned to its original state due to elasticity.

At this time, both protrusions 311 of the protrusions 310 are fixed by being hooked by the hooks 201 of the second openings 205.

That is, the projection 310 formed on one side based on the central portion 320 of the connecting member 300 is coupled to the second opening 205 of the bracket 200 to which the rubber multilayer plate 101 for the roof is coupled, The protrusion 310 formed on the other side of the connecting member 300 is coupled to the second opening 205 of the bracket 200 to which the wall rubber multilayer plate 103 is coupled.

After all, the two brackets 200 are connected to each other by one connecting member 300, and the rubber multilayer board 100 connected to each bracket 200 constitutes the roof and wall of the building.

3, the inside of the connecting member 300 is formed to be empty, but a plurality of square lattices are repeatedly formed in the space to fill the space.

Furthermore, a cross grid is formed inside the square grid, and a diagonal grid intersecting the cross grid is further formed, that is, preferably formed in a 4X-wall structure.

The external force applied to the connecting member 300 can be dispersed by such a structure, so that the durability and impact resistance of the entire building as well as the connecting member 300 are enhanced.

As described above, the rubber multilayer board 100 enhances the impact resistance of the entire building to reduce the risk of accidents from external forces, and simplifies the structure and coupling method of the connecting member 300 connecting each rubber multilayer board 100. It can be easily used by not only experts but also general users, making it easy to access and easy to assemble and use.

The disclosed content is only an example, and can be variously modified by a person having ordinary skill in the art without departing from the gist of the claims claimed in the claims. It is not limited to the examples.
