ADIABATIC BOX COMBINATION STRUCTURE FOR CURTAIN WALL < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating box coupling structure of a curtain wall, and more particularly, to a heat insulating box coupling structure of a curtain wall capable of installing a three-dimensional curtain wall.

In general, curtain wall is used for the exterior wall construction of modern buildings. It is the outer wall which does not support the load, just a partition. The load of the building is supported by the main structure of the column and the visible frame.

For this reason, curtain walls are also called non-bearing walls, curtain walls or partition walls.

Instead of supporting the load of the building, the curtain wall functions to block rain, wind, noise, and the like, and also functions as an exterior material for a beautiful appearance of the building.

As the material of the curtain wall, metal plate, glass, block, precast concrete and the like are used. Curtain walls are often used for high-rise or skyscraper buildings, and lightweight materials are used to reduce loads.

In recent years, glass has been widely used as a decorative material for construction due to the characteristics of glass, that is, transparency, openness, reflectivity and relatively light weight.

The material of the skeleton for joining the curtain walls is mainly made of aluminum or steel. Steel has superior structural strength compared to aluminum and is used as the main structure of buildings. Aluminum is used to connect the curtain wall with the steel used as the main structure of the building.

Korean Patent Registration No. 10-1109707 and Korean Patent Registration No. 10-1045648 disclose a curtain wall coupling structure for installing a curtain wall on a building.

The conventional art has disclosed a large number of extruded materials made of aluminum as a component for joining curtain walls, and the types thereof are various, and the shape is also complicated.

However, considering that the coupling operation of the curtain wall is generally carried out at the elevated position, the prior art requires a complicated combination of a plurality of extruded materials at a high altitude, an operation of preparing a large number of extruded materials at a high altitude position The inconvenience has a problem that it is difficult to secure the safety of the high-altitude operation.

In addition, a large number of protrusions protruding from a flat outer surface are formed in a large number of extruded materials, which are aluminum materials whose strength is relatively weaker than steel in the prior art. Further, the extruded materials are coupled to each other in a state where the projections are coupled, and the curtain wall is fixed and supported on the extruded material.

 However, these protrusions are subject to concentrated load due to the longitudinal pressing force of the curtain wall due to the temperature change, the strong wind and the vibration of the building, and there is a serious problem that threatens the safety of the building.

Further, considering that the extrusion unit price of aluminum is high, there is a problem that the construction cost is excessively increased because a complicated and large number of extrusion materials must be prepared.

In addition, the above-described conventional techniques are useful for constructing a two-dimensional flat curtain wall, and it is difficult to construct a three-dimensional curtain wall for a brilliant appearance. As a conventional technique for solving such a problem, Korean Patent Laid-Open Publication No. 10-2011-0100608 discloses a " conversion angle steel curtain wall and a flat, tensile force structural system for preventing buckling of a solid surface ".

In the conventional technology in which a three-dimensional curtain wall can be constructed, a steel curtain wall is installed in a hinge manner so that the angle can be adjusted. However, due to the large number of extruded materials and the complicated structure of the hinge system, it is difficult to secure the safety of the high-altitude work and the construction cost is excessively high.

Further, the curtain wall is provided to be variable by the hinge method, so that it is difficult to securely fix the curtain wall. This has a weak point against the longitudinal pressing force of the curtain wall due to the temperature change, the strong wind and the vibration of the building, and there is a serious problem that threatens the safety of the building.

It is an object of the present invention to provide a heat insulating box joining structure of a curtain wall which is capable of constructing a three-dimensional curtain wall while firmly fixing a curtain wall .

Another object of the present invention is to provide a heat insulating box joining structure of a curtain wall which can simplify the joining structure of the curtain wall and use the standard product without any additional processing.

It is another object of the present invention to provide a heat insulating box joining structure of a curtain wall which can prevent the movement of heat due to heat conduction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a heat insulating box coupling structure of a curtain wall of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an embodiment of a heat insulating box coupling structure of a curtain wall according to the present invention. 1 and 2, the present invention includes a base frame 10 constituting a frame of a building, a bracket 20 welded and fixed to the base frame, and a bolt 31 and a nut 32, A fixed curtain wall fixing frame 40 fixed to the curtain wall fixing frame, and a heat insulating box 50 fitted to the curtain wall fixing frame. The curtain wall 60 is fixed to the heat insulating box.

The foundation frame 10 of the building uses a circular pipe made of steel. Circular pipes are easy to form the appearance of various and beautiful three-dimensional buildings through cutting, bending and welding. In addition, the circular pipe can be suitably used in consideration of the structure and the load of the building.

The bracket 20 is made of a steel material such as a circular pipe so that it can be welded to a round pipe made of steel. The bracket 20 is composed of a bottom portion 21 welded to the base frame and a side wall portion 22 formed by upwardly bending both side ends of the bottom portion 21. Therefore, a draw-in groove 23 is formed between the side wall portions 22 so that the curtain wall fixing frame 40 can be drawn in. That is, the bracket 20 has a cross section of a 'C' shape.

A bolt hole (24) is formed in the side wall portion (22) so that the bolt (31) penetrates the bolt hole. The bracket 20 is welded to the circular pipe at regular intervals so that the lead-in groove 23 is located on a straight line. When the curtain wall fixing frame 40 is drawn into the inlet groove 23, both sides of the curtain wall fixing frame 40 are separated from the side wall portion 22 of the first embodiment.

This is so that the side wall portion 22 can reinforce the curtain wall fixing frame against the lateral pressing force transmitted to the curtain wall fixing frame.

The curtain wall fixing frame 40 is made of an angular pipe made of aluminum and hollow. Considering the structure of the building where the curtain wall is to be installed and the load of the curtain wall, the appropriate KS standard product can be used. In the embodiment of the present invention, a rectangular pipe is exemplified. However, it is only necessary that a flat mounting surface 41 is formed on the outer surface of each pipe so that the heat insulating box 50 can be engaged with the pipe, so that the cross-sectional shape of each pipe is not limited to a rectangular shape.

The curtain wall fixing frame 40 is drawn into the inlet groove 23 of the bracket 20 so that the mounting surface 41 is exposed and perpendicular to the drawing direction of the curtain wall fixing frame 40. [ A through hole 42 is formed at a position corresponding to the bolt hole 24 of the side wall portion 22 of the bracket 20 in the draw portion of the curtain wall fixing frame 40. The through hole 42 is formed in a rectangular shape extending in the longitudinal direction of the curtain wall fixing frame 40 and the bolt hole 24 is formed in a rectangular shape extending in the direction perpendicular to the extending direction of the through hole 42. [ As shown in FIG. Therefore, the bolt holes 24 and the through holes 42 can be easily aligned when the curtain wall fixing frame 40 and the bracket 20 are assembled, so that the assembling performance of the curtain wall fixing frame can be improved.

Bolts (31) and nuts (32) are provided as means for fixing the curtain wall fixing frame (40) and the bracket (20). Further, a flat washer 33 and a spring washer 34 are further provided to improve the fastening force between the bolt 31 and the nut 32.

On the other hand, the bracket 20 and the curtain wall fixing frame 40 are made of different materials. Corrosion may occur in the contact area at the time of bonding due to ionization tendency. In order to prevent this, a sheet member 70 for preventing mutual contact is provided at a contact portion between the curtain wall fixing frame 40 and the bracket 20.

As the sheet member 70, polyamide which is a synthetic resin is used, and polyamide 6 and polyamide 66 which are excellent in mechanical strength, heat resistance and abrasion resistance are preferably used.

The symbol 'S', which has not been described yet, is the portion finished by the silicone sealant.

FIG. 3 shows an embodiment of a heat insulating box used in a heat insulating box joining structure of a curtain wall according to the present invention. 3, the heat insulating box 50 includes a base member 51 to be engaged with the attachment surface of the curtain wall fixing frame, a heat insulating material 52 mounted on the base member 51 to prevent heat conduction, And a cap member 53 covering the heat insulating member 52 so as to be spaced apart from the heat insulating member 51.

The base member 51 has a shape in which a vertical member 51b protrudes from the center of a flat base plate 51a made of aluminum. The vertical members 51b are spaced apart from each other and extend in the longitudinal direction of the base member 51. [ Thus, a concave fitting groove is formed between the vertical members 51b. Both upper surfaces of the base plate extending from the vertical member 51b to the edge of the base plate 51a become end mounting surfaces 51c to which the ends of the neighboring curtain walls are attached so as to be spaced apart from each other. The vertical member 51b is located in the space between the end portions of the neighboring curtain walls.

A large number of piece holes 51d in which the pieces 80 are fitted are formed at the end mounting surface 51c at regular intervals. It is preferable that the plate head bolt is used for the piece 80 and the cross section of the piece hole 51d is formed in a shape similar to the dish head. Therefore, the piece head is drawn into the piece hole 51d, and the end mounting surface 51c after the piece fitting is flattened without protruding the piece head, so that the end portion of the curtain wall 60 can stably adhere and be attached.

The heat insulating bracket 90 is provided between the end mounting surface 51c and the curtain wall 60 so as to be in close contact with the end mounting surface 51c and the vertical member 51b. Referring to Figs. 1 and 2, the heat insulating brackets 90 are provided at the ends of the adjacent curtain wall 60, respectively. As the heat insulating bracket 90, a heat insulating material such as polyamide or azon, which is the above-mentioned synthetic resin, is used. Examples of the heat insulating material include, but are not limited to, glass wool, rock wool, silica heat insulation material, perlite insulation material, polyethylene insulation material, rigid polyurethane, A foamed rubber insulating material or the like may be used.

The heat insulating bracket 90 prevents heat conduction between the curtain wall 60 and the end mounting surface 51c and the vertical member 51b. The heat insulating bracket 90 is positioned at a predetermined position in the vertical direction of the heat insulating box 50 with respect to the longitudinal direction pressure of the curtain wall 60, It is possible to reinforce the member 51b.

The cap member 53 is formed in a 'C' shape by bending both ends of a flat plate made of an aluminum material so that a groove having the same width as that of the fitting groove of the base member 51 is formed.

At the end of the vertical member 51b and the cap member 53, reinforcing ribs bent to face each other are formed.

As the heat insulating material 52, azon heat insulating material which is polyurethane having low thermal conductivity is used. Azone insulation is a two-component polyurethane resin insulation, with a thermal conductivity of about 0.98 BTU per inch of thickness, corresponding to 1/1500 of aluminum's conductivity (about 1505 BTU). In addition, high tensile strength and expansion coefficient of about 5500 PSI are widely used in insulating window in correspondence with aluminum, and it is supplied from Azone Korea in Korea.

In FIG. 3, the base member and the cap member of the heat insulating box are shown as separate entities, but the base member and the cap member are integrally extruded when the heat insulating box is manufactured. Then, a space between the vertical member and the cap member is filled with an azon heat insulating material of polyurethane, and then the connection portion between the base member and the cap member is cut and removed to manufacture a heat insulating box. FIG. 4 is a cross-sectional view of the heat insulating box which is changed during the manufacturing process of the heat insulating box.

Hereinafter, the operation and effect of the present invention will be described in detail with reference to a building having a rectangular curtain wall to which a heat insulating box coupling structure of a curtain wall, which is one embodiment of the present invention, is applied.

5 and 6, there is shown a spherical building constructed by applying a heat insulating box coupling structure of a curtain wall, which is an embodiment of the present invention, and a curtain wall combined state. The base frame 10 of the rectangular building shown in Fig. 5 is constructed by cutting and bending circular pipes welded together in a lattice shape.

The curtain wall fixing frame 40 is cut and bent to have a predetermined length and curvature so as to be positioned on the upper surface of the bent circular pipe. In the present embodiment, the curtain wall is exemplified by a multi-layered glass. The glass used for the multi-layer glass is prepared by cutting and bending in a lattice unit in which a spherical shape is divided into a lattice.

The bracket 20 is pre-welded to the circular pipe before it is welded in a lattice shape. Then, the curtain wall fixing frame 40 and the heat insulating box 50 are pre-joined on the ground.

The heat insulating box 50 is not bent but is engaged with the outer surface of the curtain wall fixing frame bent at a predetermined curvature. Therefore, the heat insulating box 50 is bent and joined to the curvature of the curtain wall fixing frame.

Since the curtain wall fixing frame 40 and the heat insulating box 50 are coupled in advance on the ground in this manner, the clamping operation of the bracket 20 and the bolts and nuts for fixing the curtain wall fixing frame 40, Only the operation for finishing the wall 60 by attaching the glass 60 to the silicone sealant is performed. Therefore, the workability can be improved by simplifying the work, and the safety of the job for the elevation can be improved.

Meanwhile, the inside of the curtain wall fixing frame 40 is hollow, and air in the building flows through the hollow portion. At this time, heat exchange occurs between the air and the curtain wall fixing frame 40. Therefore, the heat conducted to the heat insulating box 50 through the curtain wall fixing frame 40 can be minimized. Also, in the heat insulating box 50, the base member and the cap member are separated from each other by the azine insulating material, thereby preventing the heat conduction.

The curtain wall fixing frame 40 has a closed-end shape in cross-section, and there is no joining portion of the projections protruding from the outer surface as in the prior art. There is no portion that can receive a concentrated load due to the longitudinal direction pressing force of the curtain wall, and the load is dispersed. Further, since the side wall portion 21 of the bracket 20 reinforces the curtain wall fixing frame 40 with respect to the lateral pressing force, the structural strength is improved as compared with the conventional technique.

While the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.

Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
