Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a sandwich panel which is a lightweight building material, and particularly to provide a sandwich panel having excellent strength while using an iron plate having the same specifications.

I. The technical problem the invention is trying to solve.

The conventional lightweight sandwich panel uses a steel plate of constant thickness in terms of ease of processing and economical cost reduction, and thus the length or width of the sandwich panel is determined according to the use of the iron plate.

However, such a length or width of the panel has a problem that the limitation of the size is generated during the construction of the building and the burnout of the panel due to the increase in load depending on the size.

All. The gist of the solution of the invention.

Therefore, in the present invention, a plurality of vertical bones having inclined surfaces with a predetermined depth are formed on the iron plate so as to sufficiently cope with vertical loads and horizontal loads due to the inclined surfaces and vertical bones.

Description

Sandwich panel which has vertical bone for reinforcement {Sandwich panel which has supporting vertical groove}

The present invention is designed to use the same number of steel plates that are already used, while producing an appropriate number of vertical bones in a sandwich panel, which is a lightweight building material, in particular by reinforcing bend lines formed to cope with vertical or horizontal loads. It is to provide a panel with excellent cost reduction and strength.

Conventional lightweight sandwich panels have been provided by bonding a styropole having a predetermined thickness between steel sheets facing away from each other by a special thermal polymerization method.

Light weight sandwich panel has 21.5 times better insulation than red brick, excellent moisture and waterproof effect, low unit cost, easy installation and disassembly, low construction period and maintenance cost, so it is widely used in construction of prefabricated buildings. As a result, the spread of new building materials is increasing.

However, the width of the above-mentioned light weight sandwich panel is determined by the specification of the supplied steel sheet, and both surfaces are made of a relatively thin 0.4-0.5 mm colored steel sheet or galvalume steel sheet, and the surface has its own weight or assembly time. In order to prevent breakage such as folding or bending due to the vertical and horizontal loads applied, a plurality of vertical bones are formed by reinforcing bent lines formed vertically by a sequential process from the center of the steel sheet entering the molding machine to the both ends. Lose.

However, the vertical bone formed by the above reinforcement bending line is not deep enough to be bent or folded due to strong winds during installation work or movement, which often results in a small standard, which is why when building a large building, The use of such panels was quite difficult.

The present invention is designed to solve the problems described above, which is formed by the reinforcement bending line to increase the depth of the vertical bone formed in the iron plate width 1040 and the thickness within 0.4 ~ 0.5mm and deepen the depth The number of vertical bones is less than three or four, but enough to cope with vertical and horizontal loads.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Sandwich panel 100 of the present invention is a color steel sheet, galvalume steel sheet, etc. as both sides of the insulating material 20, such as rectangular styropole (EPS) or urethane foam having a predetermined thickness, length and width as shown in Figs. Surface material 30 is bonded by urethane foam bonding.

At this time, in the longitudinal direction of the surface of the surface material 30, a plurality of longitudinal bones 32 having a yaw-shaped cross section having a predetermined depth spaced apart by a predetermined distance to correspond to the weight or external force of the panel 100 is reinforced. It is formed by a bent line, the cross-sectional shape may be made of a trapezoidal shape as shown in Fig. 1, or may be formed in various forms such as a semicircle as shown in B of Fig. 1, but particularly in the case of a longitudinal bone 32 of trapezoidal shape. Opposing sides must have non-parallel slopes to correspond to horizontal loads acting in the transverse direction.

In addition, the vertical bone 32 is formed to three or four or less in order to shorten the manufacturing process, but can be sufficiently corresponding to the vertical and horizontal load by being formed larger and deeper than the vertical bone formed in the conventional sandwich panel.

In addition, between the plurality of longitudinal bones 32 formed at a predetermined distance apart, a reinforcement line 34 having a corrugated cross section may be formed to give an aesthetic sense to the surface of the monotonous surface material 30, and to improve durability. And surface treatment such as fluorine coating.

Meanwhile, both ends of the pair of surface members 30 bonded to both sides of the heat insulating material 20 are provided with insertion holes 110 at one end thereof and ends with the insertion holes 110 at the other end thereof. An insertion hole 112 to be inserted is provided.

Sandwich panel 100 of the present invention configured as described above, both surface material 30 is flame retardant and is safe for fire or flame, and Schiropol forming a heat insulating material 20 sandwiched between the surface material 30 is characterized by low moisture absorption rate The present invention sandwich panel 100 exhibiting a perfect waterproof effect and moisture-proof effect by having a reduction in the manufacturing cost by shortening the manufacturing process by sufficiently responding to the vertical and horizontal loads acting while reducing the number of vertical bone 32 to be molded The effect is to achieve.

The sandwich panel of the present invention shortens the forming process of the surface steel sheet for fabrication, thereby reducing the size of equipment, reducing the manufacturing cost, increasing productivity, and bending or folding by fully coping with the vertical and horizontal loads caused by the panel's own weight or external force. It is effective in preventing the disposal of the sandwich panel and the worker's injury by preventing the back.
