Description

Vertical frame for steel curtain wall system and structure for coupling frames}

The present invention relates to the structure of the support frame of the steel curtain wall system (steel curtain wall system), and more particularly, to the structure of the vertical frame of the steel curtain wall of the building consisting of a laminated glass and the coupling structure of the support frame will be.

In general, in the structure that supports the vertical load applied to the building and the horizontal load caused by wind or earthquake, etc., only the frame of pillar and beam, which are the main structure of the building, the wall merely serves as a curtain to prevent the space. The wall at this time is called a 'curtain wall' or 'non-bearing partition wall'. In recent years, the wall surface using the glass which prevents rain or wind from the outside, blocks noise or heat, and prevents the columns and beams from being exposed to the outside has gained great popularity as a modern architectural style with exterior functions. The curtain wall used as the exterior wall panel as described above was generally the first curtain wall made of aluminum, but in recent years, architects tend to have higher floor heights and wider unit walls. It is called 'steel curtain wall' because it uses steel material, which is three times stronger in structure.

      The structure of such a steel curtain wall support frame, as illustrated in Figure 1 (a), Figure 1 (b), Figure 1 (c) and Figure 1 (d), and the vertical frame (mullion) (1) and Each of the transoms 2 is a vertical and horizontal solid t-bar type frame 1a and 2a or an improved vertical from the solid T-type frames 1a and 2a. It is generally formed by forming type and horizontal forming bar type frames 1b and 2b, and these have a structure in which they are joined to each other by a welding coupling method or a bolt-nut coupling method.

However, the vertical frame and the horizontal frame constituting the curtain wall as described above have a problem that the assembly work is difficult because they are mainly used for a high floor and a wide wall surface, and the frame has a performance (support) of the building structure. In order to maintain the strength, it is difficult to select the material, shape and structure of the support frame, such as steel material and expensive aluminum material to reduce the support load. In addition, when the horizontal frame and the vertical frame are coupled to the outside with bolts and nuts, they are exposed to the outside, which lowers the aesthetic appearance, and when they are welded, sophisticated assembly work may be difficult and assembly labor costs may be increased. In the case of using a solid T-shaped frame, there is a drawback that it is difficult to maintain the material cost and maintain the shape of the frame.

As an example of the forming frame which is increasing in the above-mentioned manner, the vertical frame 10 of the steel curtain wall shown in Korean Patent Application No. 2007-0048102 (filed on May 17, 2007) is shown in FIGS. As shown in FIG. 2 (b), a pair of vertical members 11 installed vertically opposite to each other, a plurality of reinforcing members 12 coupled to each other between the vertical members 11, and the reinforcing member ( It is formed on one side of the 12 and the pressure plate 21 is coupled to the cover 23 is composed of a bracket 14 is coupled by a bolt with a gap retaining 22 therebetween, the vertical frame 10 A plurality of inner plates 15 are installed in the vertical member 11 and the reinforcement 12 so as to maintain the vertical directions, respectively, and the air circulation is blocked inside the vertical frame 10 due to the inner plate 15. A plurality of spaces are formed. In the drawings, reference numerals 20 and 24 denote horizontal frames and multilayer glass, respectively.

However, the vertical frame has to be provided with a separate inner plate, etc. to increase the supporting strength, the work is cumbersome, the support strength is not secured stably compared to the difficult work, occupied space occupied by the interior space and the projections There are a lot of things and the appearance was not so neat.

In addition, as a prior art of the coupling structure of the forming frame, the steel curtain wall system proposed in Korean Patent Application No. 2005-0106996 (filed Nov. 09, 2005), Figures 3 (a) and 3 (b) As shown in FIG. 2, the vertical frame 10 is formed of steel and has a plurality of support holes 31 on both sides, and the plurality of moldings formed of steel and inserted into the support hole of the vertical frame on one side. Consists of a horizontal frame 20 is provided with a support member (32). In the figure, reference numeral 21 denotes a pressure plate, 22 denotes a gap retaining zone, 23 denotes a cover, and 24 denotes a multilayer glass.

      The combined structure of the vertical frame and the horizontal frame of the steel curtain wall system also does not overcome the disadvantage that the structural performance is lower than the occupied space of the forming frame, and thus could not be expected a solid coupling structure performance.

The present invention has been made to solve the above problems, and an object thereof is to provide a vertical frame of a steel curtain wall system having a high support strength while using as little as possible the frame metal material.

Another object of the present invention is to provide a coupling structure of the frame of the steel curtain wall system, which is simple and firmly combined with the vertical frame of the steel curtain wall system configured as described above, and has aesthetic appearance.

The vertical frame of the steel curtain wall system according to the present invention for achieving the above object is a reinforcement frame formed of an elongated metal plate, and a longitudinal portion surrounding the outer surface of the reinforcement frame and the front side perpendicular to the longitudinal portion. It is characterized by consisting of a metal shell of a hollow T-shaped cross section having a transverse direction portion (on the glass mounting surface side).

In addition, the frame coupling structure of the steel curtain wall system according to the present invention is a reinforcement frame formed of a long metal plate, and the longitudinal portion surrounding the outer surface of the reinforcement frame and the front side perpendicular to the longitudinal portion (glass installation A vertical frame composed of a metal shell of a hollow T-shaped cross section having a transverse portion of the plane side); A horizontal frame assembly bracket fixedly installed at a horizontal frame arrangement position of the vertical frame; And a metal shell of the hollow T-shaped cross section of the vertical frame. It has the same or slightly smaller shape, characterized in that it comprises a horizontal frame is assembled to the mounting bracket for the horizontal frame is coupled to the grid in the vertical frame.

 According to a preferred embodiment of the present invention, the horizontal frame assembly bracket is a horizontal flat plate is fixed to the vertical frame by a slotted welding method, a vertical flat plate fixed to the surface contact welding method for the vertical frame, or the The horizontal plate portion for the vertical frame and the vertical plate portion for the horizontal frame include a T-Cleat that is fixed in a screw manner.

The vertical frame of the steel curtain wall system according to the present invention configured as described above, while using less metal material used in the frame, the performance of the building structure is very high, and also gives the appearance aesthetic effect.

In addition, the frames of the steel curtain wall system according to the present invention provides a frame coupling structure that is firmly coupled to each other quickly, easily and in appearance.

Then, the technical configuration of the vertical frame and frame coupling structure of the steel curtain wall system according to the present invention will be described in detail with reference to the accompanying drawings.

4 is a perspective view of a vertical frame of a steel curtain wall system according to the present invention.

As shown in Fig. 4, the vertical frame 40 of the steel curtain wall system according to the present invention consists of a reinforcing frame 41 and a metal shell 42 of hollow T-shaped cross section. The reinforcing frame 41 is usually a long metal flat plate made of steel, and in some cases, an aluminum material is also possible. In addition, the metal shell 42 of the hollow T-shaped cross section is a metal sheet metal formed integrally with the longitudinal part 43 surrounding the outer surface of the reinforcing frame 41 and the front side with respect to the longitudinal part. Is divided into a transverse portion 44 that is orthogonal to. The transverse portion 44 extends the protrusions 45 vertically along the front both outer and outer ends so that the mechanisms necessary for installing the multilayer glass are properly supported. In the vertical vertical portion on the front side of the transverse portion 44, a spaced portion 46 extending vertically spaced by the thickness of the frame body to facilitate insertion of the reinforcement frame 41 is extended. The vertical frame 40 configured as described above can be easily assembled by placing the reinforcing frame 41 upright, and then aligning and inserting (extrapolating) the metal shell 42.

The structure of the vertical frame 40 as described above has the disadvantages of the above-mentioned solid T-shaped frame, that is, it is difficult to maintain the vertical state of the shape, but the weight and cost, and the weak supporting strength and relatively occupied It can be said that the structure that can solve the shortcomings that the space becomes large at a time. That is, the amount of metal material and material cost used in the solid T-shaped frame is reduced by the empty space provided in the transverse portion 44 of the metal shell 42, and furthermore, the weight of the frame is reduced to reduce the load of the building. It is possible to maintain its shape (vertical state) well. In addition, there is an advantage that the space of the remaining width of the transverse portion 44 as long as the length of the longitudinal portion 43 of the metal shell 42 can be further utilized as the interior space.

Next, the frame coupling structure of the steel curtain wall system according to the present invention will be described.

5, 6 and 7 are exemplary views showing the combination of the frames of the steel curtain wall system according to the present invention according to various embodiments.

As shown in these figures, the frame system of the steel curtain wall according to the present invention, the horizontal frame assembly bracket 50 at the position where the horizontal frame is installed relative to the vertical frame 40 configured as shown in FIG. ) Is fixedly installed, and the horizontal frame 60 is assembled in the horizontal direction on the fixedly mounted horizontal frame assembly bracket 50, so that the horizontal frame 60 is finally gridded on the vertical frame 40. It has a structure to be bonded.

The frame system of the steel curtain wall configured as described above will be described first in the order of the vertical frame 40, the horizontal frame 60, and the bracket for assembling the horizontal frame 50, and then the coupling structure thereof is comprehensively described. Let's explain.

First, since the vertical frame 40 has been described with reference to FIG. 4, further description thereof will be omitted.

The horizontal frame 60 has a structure in which the reinforcement frame 41 is excluded from the structure of the vertical frame 40 and has only a metal shell 62. The metal shell 62 has the same material and shape as the metal shell 42 of the vertical frame 40, but the size of the longitudinal portion 63 is the longitudinal portion 43 of the vertical frame 40. It may be formed smaller than the width and thickness of). This mechanically reduces the structural shape since the horizontal frame 60 receives relatively less load than the vertical frame 40, and can also exclude internal support members such as reinforcement frames. In addition, the width and thickness of the transverse portion 64 of the horizontal frame 60 are preferably the same as the width and thickness of the transverse portion 44 of the vertical frame 40 so that the longitudinal lattice plane of the glass mounting portion is constant. It is desirable to form. Of course, the width and thickness of the transverse portion 64 of the horizontal frame 60 may be formed to be slightly smaller than the width and thickness of the transverse portion 44 of the vertical frame 40, in some cases economical In the case where priority is given to solid support than the side surface, the inside of the horizontal frame 60 may be provided with a metal flat plate as a reinforcement frame like the structure of the vertical frame 40.

On the other hand, the bracket for assembling the horizontal frame 50 is composed of one flat plate or two flat plates, and is installed in the vertical frame 40 in various shapes and fixed shapes as illustrated in FIGS. 5 to 7.

Then, the shape of the bracket for mounting the horizontal frame 50 and the structure in which the frames are coupled thereto will be described in detail with reference to FIGS. 5 to 7.

 First, in the first embodiment shown in FIGS. 5 (a) and 5 (b), the metal shell 42 of the vertical frame 40 is properly cut out so as to be lattice-coupled with the horizontal frame 60 in advance. Thereafter, the fixing part 52 of the horizontal frame assembly bracket 50a formed of the horizontal flat plate 51 with respect to the reinforcing frame 41 of the vertical frame 40 is welded and fixed by the slotting welding method. As the horizontal frame assembly bracket 50a and the horizontal frame 60 are assembled by matching the internal space of the longitudinal portion 63 of the horizontal frame 60 with respect to the fixed horizontal frame assembly bracket 50a, The vertical and horizontal frames of a steel curtain wall system are joined together. At this time, the thickness of the bracket for mounting the horizontal frame (50a) is equal to or slightly smaller than the internal gap of the longitudinal portion 63 of the horizontal frame 60 for proper coupling.

As mentioned above, the shape of the coupling structure is easily maintained by the vertical frame 40 having the reinforcing frame 41, and there is almost no risk of damage to the coating even when the fixing part 51 is grooved. , Without additional finishing work, the horizontal frame assembly bracket (50a) is hidden inside the frame without being exposed to the outside to maintain the aesthetics, as well as the material cost and work costs are reduced.

Next, in the second embodiment shown in Figs. 6A and 6B, the vertical flat plate 53 is equal to the width and thickness of the inside of the transverse portion 64 of the horizontal frame 60. It is formed to be slightly smaller so that the fixing part 55 of the horizontal frame assembly bracket 50b in which one or more horizontal frame joining spiral holes 54 are drilled on the flat plate so as to be lattice-coupled with the horizontal frame 60 in advance. The metal shell 42 of the vertical frame 40 is welded and fixed by the side contact welding method on the side in accordance with the front surface of the reinforcement frame 41, which is appropriately cut, and with respect to the fixed horizontal frame assembly bracket 50b. The inner space of the transverse portion 64 of the horizontal frame 60 is matched, and a screw (not shown) into the spiral hole 54 for horizontal frame coupling through the metal shell 62 of the horizontal frame 60. By fixing the horizontal frame assembly bracket 50b and the horizontal frame 60 is assembled, thereby the steel cover The wall system is firmly secured to each other in a state in which the horizontal frame assembly bracket 50b formed of the vertical flat plate 53 having the spiral hole 54 and the welding fixing part 55 is hidden inside the frame without being exposed to the outside. It will have a structure that is smoothly combined. This coupling structure also has the advantage that the material cost and the work cost are reduced as in the first embodiment.

In addition, in the third embodiment shown in Fig. 7 (a) and Fig. 7 (b), the horizontal frame assembly bracket 50c is a horizontal frame as a T type bracket (T-Cleat) as shown in Fig. 6 above. The vertical plate portion 53 (the welding fixing portion 55 does not exist here) in which the coupling spiral holes 54 are perforated, and vertically coupled to each other in the rear with respect to the vertical plate portion 53. It includes a horizontal plate portion 57 is formed with one or more spiral frame 56 for coupling the vertical frame penetrated toward the reinforcement frame 41 of the vertical frame 40. The bracket 50c for horizontal frame assembly having such a shape is first formed on the reinforcing frame 41 of the vertical frame 40 by the spiral hole 56 for vertical frame coupling of the horizontal flat plate 57. After mating to the holes 47, screws (not shown) are fixed through these holes 56 and 47, and then the horizontal frame 60 is assembled to the horizontal frame assembly bracket 50c, and then horizontal Screws (not shown) are provided through the holes (not shown) provided in the metal shell 62 of the frame 60 to the horizontal frame coupling spiral holes 54 provided in the vertical plate portion 53 from the outside. By fixing the vertical frame 40 and the horizontal frame 60 is to be combined. It is a big feature that the welding operation is excluded in the coupling structure.

The steel curtain wall system having such a coupling structure is firmly secured to each other in a state where the bracket for horizontal frame assembly 50c formed of the vertical flat plate 53 and the horizontal flat plate 57 is hidden inside the frame without being exposed to the outside. It will have a structure that is smoothly combined. Like the first and second embodiments, this coupling structure also has the advantage of reducing the material cost and the working cost and further strengthening the bonding strength.
