As the outer wall panel for curtain wall, a glass panel which is a typical exterior material is mostly used, and in order to prevent heat loss, double glass or heat ray absorbing glass is mainly used.

The curtain wall is used to block rain or wind from the outside and to block noise and heat, and the column and the beam are not exposed to the outside, and the wall using glass or the like has a large function as the exterior. Especially, it is widely used for high-rise or super-high-rise construction, and it is difficult to assemble scaffolding outside the building with height of 100m or more.

The basic structure of such a curtain wall is composed of a glass panel and a structural material such as a mullion and a transom of steel or aluminum alloy for fixing the glass panel. In addition, since the weight of the glass panel is very heavy, the strength and supporting force of the structural member supporting the glass panel and the supporting member for fixing the glass panel to the structural member are very important.

Particularly, a dovetail groove is formed in the center of the fixing plate at the front of the steel frame in the longitudinal direction, and an á-shaped wedge piece is fitted in the dove tail groove. An inner gasket is provided on both side fixing plates of the dove tail groove, An outer gasket corresponding to the gasket is provided so that the edge of the multilayer glass is abutted between the inner gasket and the outer gasket so that the washer bolt is screwed to the wedge piece inserted into the dovetail groove of the steel frame from the outside of the bracket.

However, in the conventional steel curtain wall described above, it is difficult to accurately fasten the screw for fixing the glass panel to the center of the joint portion of the steel frame (i.e., steel structural member). Therefore, there is a high possibility that the screw for fixing the glass panel is warped in a distorted state at the center portion of the steel structural member. As a result, a clearance is formed in the fastening portion, and it becomes difficult to join the outer cover. The rainwater penetrates through the gap and the steel structural member may be corroded, and the aesthetic appearance may be damaged. In addition, since there is no means for preventing the inflow of cold air between the glass panels, not only the heat insulating performance is lowered in winter but also the rainwater blocking effect is lowered and the steel structural material is corroded.

2 to 5, in the steel curtain wall coupling structure illustrated in the embodiment of the present invention, a dovetail groove 11 is formed in a front portion of a steel structural member 10, The present invention is applicable to a structure in which the glass panel 20 is provided on the front side of the groove 11.

In the following description of the embodiments, glass panels 20 are disposed on the upper and lower sides of the steel structural member 10, respectively, but the glass panels 20 are disposed on the left and right sides, It is needless to say that the present invention can be similarly applied to an example in which the structural member 10 is installed.

The wedge piece 30 is inserted into the dove tail groove 11 and the first gasket 40 is installed between the front portion of the steel structural member 10 and the glass panel 20, A second gasket (50) corresponding to the first gasket (40) is provided outside the panel (20). When the glass panel fixing screw 70 is inserted into the dovetail groove 11 of the steel structural member 10 from the outside of the inner cap 60 while the inner cap 60 is installed on the outer side of the second gasket 50, And is engaged with the wedge member (30).

The above-described structure is a known element that can be seen also in a coupling structure of a conventional steel curtain wall. Although the first gasket 40 and the second gasket 50 prevent heat from escaping from the inside to the outside and prevent penetration of rainwater or the like from the outside to the inside, 40 and the second gasket 50 alone, it is difficult to expect sufficient heat insulating performance and moisture barrier performance. Moreover, it is difficult to accurately fasten the glass panel fixing screw 70 to the center of the joint portion of the steel structural member 10. [ Therefore, there is a high possibility that the glass panel fixing screw 70 is screwed in a state of being bent at the center portion of the steel structural member 10, so that a clearance is generated at the fastening portion, The steel structure 10 may be corroded, and the appearance of the steel structure 10 may be damaged.

The present invention solves the above problems through the following design changes and additional components.

The structure of the wedge piece 30 has been conventionally opened in a direction opposite to the direction in which the wedge piece 30 is inserted into the dove tail groove 11. However, the wedge piece 30 of the present invention is inserted into the dove tail groove 11 And the opening 31 is formed in the direction of the opening.

When the glass panel fixing screws 70 are coupled toward the wedge pieces 30, the glass panel fixing screws 70 (see FIG. 1) And a wedge groove 111 is formed at a position where the wedge groove 111 is joined. The wedge groove 111 is formed to be straight in a straight line toward the first V-notch groove 32 of the wedge piece 30. When the glass panel fixing screw 70 is engaged with the wedge piece 30 The pointed tip of the glass panel fixing screw 70 is directed to the first V-notch groove 32 of the wedge piece 30 through the wedge groove 111 so that the glass panel fixing screw 70 is inserted into the wedge piece 30 To be precisely coupled to the center of the body. The first heat insulating material 110 is further formed with a coupling groove 112 on the outer side of the wedge groove 111. The following third gasket 120 is coupled to the coupling groove 112.

The third gasket 120 is joined to the coupling groove 112 of the first heat insulating material 110 between the second gasket 50 and the first heat insulating material 110 to form the second gasket 50 and the glass panel 20, And to block the cold air and moisture that flow in from between. The third gasket 120 may be positioned between the upper glass panel 20 and the lower glass panel 20 when the upper and lower pairs of glass panels 20 are disposed, And is positioned between the glass panel 20 on the left side and the glass panel 20 on the right side when the pairs are arranged. This is a structure in which a gasket is not interposed between glass panels in a conventional steel curtain wall coupling structure.

In order to prevent the third gasket 120 from being detached from the coupling groove 112 of the first thermal insulation member 110, the coupling groove 112 of the first thermal insulation member 110 may be provided with an example of ' And the third gasket 120 may be provided with a latching protrusion 121 for latching the latching protrusion 112a.

Particularly, the third gasket 120 may be provided with a closed loop type buffer part 122 located between the glass panel 20 and the first heat insulating material 110, Since the buffer part 122 has a structure in which a space is formed in the buffer part 122, the impact due to the load of the glass panel 20 disposed on the upper side is alleviated, It is possible to prevent the penetration of cold air and moisture between the first heat insulating member 20 and the first heat insulating member 110.

3, the water penetrated through the upper side gap of the upper glass panel 20 and the second gasket 50 is guided to the lower side of the lower glass panel 20 and the second gasket 50, A downward inclination and a vertically downward extension between the glass panel 20 and the second gasket 50 at the lower side of the second gasket 50 to guide the gasket 50 to be discharged to the outside through the lower- (123) may be formed.

When the glass panel fixing screw 70 is engaged with the wedge piece 30, the pointed tip of the glass panel fixing screw 70 is inserted into the wedge groove (not shown) of the first heat insulating member 110 111 may be formed in a straight line with the wedge groove 111 of the first heat insulating member 110 and the first V-notch groove 32 of the wedge member 30. The V-

On the other hand, when the wedge piece 30 is inserted into the dove tail groove 11 of the steel structural member 10, a second heat insulating material 130 interposed between the wedge piece 30 and the dove tail groove 11 is provided . The second insulation member 130 is made of a PVC material and has a function of insulating the wedge member 30 and the dove tail groove 11 as well as a function of insulating the wedge member 30 and the dove tail groove 11, (11) is prevented from coming into direct contact. In other words, unlike the steel structural member 10 made of steel, the wedge member 30 is made of the same material as aluminum. In general, when metals of different materials are in direct contact with each other, contact corrosion occurs. A second insulating material 130 made of a non-metallic material is interposed between the wedge pieces 30 and the dove tail grooves 11.

Particularly, when the glass panel fixing screw 70 is engaged with the wedge piece 30 while the second insulating member 130 is opened in a direction to be inserted into the dove tail groove 11, And a second V-notch groove 131 is formed at a portion where the second V-notch groove 70 is coupled. The second V-notch groove 131 is formed in the first V-notch groove 32 of the wedge piece 30 and the first V-notch groove 32 of the first wedge piece 30 in a straight line with the wedge groove 111 of the first heat insulating material 110. [ Notch groove 32 so that when the glass panel fixing screw 70 is engaged with the wedge piece 30, the pointed tip of the glass panel fixing screw 70 is fixed to the first heat insulator 110 Notch groove 32 of the wedge piece 30 after passing through the wedge groove 111 of the first insulating material 130 and the second V-notch groove 131 of the second insulating material 130 in this order, (70) can be accurately engaged with the center of the wedge piece (30).

In order to prevent the second heat insulating material 130 from falling in a direction opposite to the direction in which the second heat insulating material 130 is inserted into the dovetail groove 11 in a state where the second heat insulating material 130 is coupled to the wedge piece 30, And an engaging protrusion 132 is formed at the open end of the second heat insulating member 130. The engaging protrusion 132 is engaged with the engaging groove 33 of the wedge member 30. [

The first heat insulating material 11, the second heat insulating material 130 and the wedge pieces 30 may be fixed to each other by a fixing screw 140. The fixing screws 140 are fixed to the glass panel fixing screws 70 The first heat insulating material 11, the second heat insulating material 130 and the wedge pieces 30 are fixed to each other at a position where they are not interfered with.

The joining structure of the steel curtain wall according to the present invention constructed as in the above embodiment is characterized in that the joining structure of the steel curtain wall comprises a dove tail formed on the front portion of the steel structural member 10 for fixing the glass panel 20 to the front side of the steel structural member 10.

At this time, the wedge groove 111 of the first heat insulating material 110, the second V-notch groove 131 of the second heat insulating material 130, and the first V-notch groove 32 of the wedge piece 30, And they are aligned with each other along the joining progress direction of the fixing screws 70.

The wedge piece 30 and the second heat insulating material 130 are inserted into the dovetail groove 11 of the steel structural member 10 and inserted into the inner side of the glass panel 20 disposed on the front side of the steel structural member 10 The first gasket 40 is interposed between the first gasket 120 and the first heat insulating material 110 and the third gasket 120 is coupled to the first heat insulating material 110 in the middle of the glass panel 20, do. A second gasket 50 is provided on the outer side of the glass panel 20 and the inner cap 60 is coupled to the outside of the second gasket 50.

In this state, the operator attaches the glass panel fixing screw 70 to the wedge piece 30 inserted in the dovetail groove 11 of the steel structural member 10. At this time, the glass panel fixing screw 70 The pointed end portion is guided to the wedge groove 111 of the first heat insulator 110 through the V-notch groove of the third gasket 120 while passing through the inner cap 60 and the second gasket 50 in turn, Through the second V-notch groove 131 of the heat insulating material 130 to the first V-notch groove 32 of the wedge piece 30 and abuts against the center of the wedge piece 30. [ Therefore, the pointed tip of the glass panel fixing screw 70 can be precisely engaged with the center of the wedge piece 30.
