Description

CAP TYPE COMBINATION STRUCTURE FOR CURTAIN WALL}

The present invention relates to a coupling structure of a curtain wall, and more particularly to a cap-type coupling structure of a curtain wall to press the end of the neighboring curtain wall to construct the curtain wall.

In general, the curtain wall is used for the exterior wall construction of modern buildings and refers to the outer wall that merely serves as a partition and does not support a load. The load of the building is supported by the pillars and the visible frames. For this reason, curtain walls are also called non-bearing walls, curtain walls or partition walls.

As the wall material, metal plates, glass, blocks, and precast concrete are used. Curtain walls are often used in high-rise or high-rise buildings, where light materials are used to reduce the load. In recent years, a double-layered glass is widely used as a curtain wall due to the characteristics of glass, i.e., transparency, openness, reflectivity and relatively light weight.

Such curtain wall functions as an exterior material for the beautiful appearance of the building, and serves to block rain, wind, noise, and heat. Curtain walls are joined together in multiple grid units and finished with silicone sealant.

In general, however, curtain walls have problems such as leakage problems between the ends of neighboring grid curtain walls, thermal insulation problems, and weakness of the curtain wall joints due to wind pressure.

In order to solve this problem, a combination structure of various curtain walls is being developed. Korean Patent Publication No. 10-1045648 (hereinafter referred to as “Prior Art 1”) and Korean Patent Publication No. 10-0648441 'Prior Art 2' discloses a coupling structure of a curtain wall to solve the above problem.

Coupling structure of the steel curtain wall of the prior art 1 is a wedge piece is fitted into the dovetail groove formed in the center of the front middle plate of the steel frame ('curtain wall fixing frame' of the present invention), and close to the edge of the adjacent laminated glass The bracket is introduced from the outside of the bracket is a structure for pressing the multilayer glass by the washer bolt fastened to the wedge piece. The inner gasket fixing member provided with the inner gasket is fixed to the wedge piece by a fixing bolt, and an outer gasket is provided inside the bracket.

However, the prior art 1 is a structure in which the bracket and the wedge piece are coupled only on the long washer bolt, which is vulnerable to the curtain wall joint because it depends only on the strength of the washer bolt against the longitudinal transverse pressure of the curtain wall. I still have a problem. Of course, to compensate for this, the number of washers may be increased or the size may be increased, but a large amount of time and effort are put into the assembly, and accordingly, other assembly materials such as steel frames, dovetail grooves, and wedge pieces are enlarged. Due to the increase in load, there is a problem that the manufacturing cost is increased.

In addition, since the steel frame, the wedge piece, the washer bolts are coupled to each other while being in close contact with each other without a separate insulating material, heat exchange with the outside due to heat conduction is made, and thus there is a problem that the heat insulation of the curtain wall cannot be solved.

Meanwhile, in the steel curtain wall system of the prior art 2, the adapter is screwed to the front of the vertical and horizontal frames (which is the 'curtain wall fixing frame' of the present invention), and the support and the pressure plate are continuously adhered to the adapter to be fastened to the adapter. It is a structure that is fixed by the fixing means. The laminated glass (curtain wall) has its ends fixed between the vertical and horizontal frames and the pressure plates. Then, the backing material is inserted into the vertical and horizontal frames, the laminated glass (curtain wall), the laminated glass and the adapter, the pressure plate and the laminated glass, and the sealing material is coated.

However, in the prior art 2, since the coupling position of the adapter and the fixing means is located in the space between the adjacent laminated glass, the coupling portion is subjected to a concentrated load for the lateral pressure, and thus, an unstable coupling problem is likely to occur. to be. Therefore, the prior art 2 still has the problem of the vulnerability of the curtain wall coupling portion due to the wind pressure.

Of course, to compensate for this, the size of the adapter and the fixing means can be increased, but considering that the assembly position is a narrow space between the laminated glass, there is a limit to increasing the size, and the load increases due to the enlargement of the assembly parts. There is a problem that the production cost increases.

In addition, the prior art 2 also has a problem that the vertical and horizontal frame, the adapter, the support, the pressure plate is a structure that is fixed in close contact with each other, the heat insulation of the curtain wall by heat exchange with the outside due to heat conduction.

The present invention was devised to improve the above problems, and an object of the present invention is to provide a cap-type coupling structure of a curtain wall so that the curtain wall can be firmly fixed even in the transverse pressure caused by the wind pressure.

In addition, the present invention is to provide a cap-shaped coupling structure of the curtain wall so that the movement of heat by heat conduction can be blocked.

In addition, the present invention is to provide a cap-type coupling structure of the curtain wall to improve the airtightness of the curtain wall so that no leakage occurs.
