Description

Support frame for steel curtain wall construction and steel curtain wall construction structure using the same

The present invention relates to a support frame structure for constructing a steel curtain wall of a building, and more particularly, to a support frame for constructing a steel curtain wall and a steel curtain wall construction structure using the same, which are simple in construction work, excellent in construction quality, and capable of reducing construction costs by shortening the construction period, by realizing construction without welding work in the field in contrast to the existing steel curtain wall construction method, which was constructed by welding in the field.

In general, in a structure that supports the vertical load applied to the building and the horizontal load caused by wind or earthquake, only with the framework of pillars and beams, which are the main structures of the building, the wall simply serves as a curtain that blocks the space.

Recently, walls using glass, etc., which block rain and wind from the outside, block noise and heat, and prevent columns and beams from being exposed to the outside, are in the limelight as a material for modern buildings with exterior functions. Curtain walls used as exterior wall panels of buildings were initially made of aluminum, but in recent years, architects' architectural design tendencies have pursued unit walls with high heights and wide widths. As a curtain wall material, steel, which is several times stronger in structural strength than aluminum, is often used, and it is referred to as a 'steel curtain wall'.

On the other hand, in the support frame 30 structure for the existing steel curtain wall built-up construction, as shown in FIG. 1, a plurality of horizontal members 20 are formed between a pair of vertical members 10 at regular intervals. It is formed in a coupled structure. In this case, the vertical member 10 is manufactured through welding in a factory to have a cross-sectional structure in the form of a 'C' shape to form a reinforcing structure, and the horizontal member 20 is manufactured in a way that welds the horizontal member 20 again in the field.

However, since the support frame 30 of the above structure is mainly used for constructing a wall body with a high floor height and a wide width during the steel curtain wall built-up construction, there is a problem in that the construction work is very difficult. In addition, the support frame 30 has many difficulties in selecting the material, shape, structure, etc. of the support frame 30, such as using a steel material to maintain the support strength of the building structure or using an expensive aluminum material to reduce the support load.

In addition, in the case of steel curtain wall built-up construction using the support frame 30 having the above structure, since the construction is performed by welding and assembling the vertical member 10 having a 'C' cross-section shape manufactured in advance at the factory and the horizontal member 20 at the site, it is difficult to precisely assemble the vertical member 10 and the horizontal member 20, and there are disadvantages in that labor cost increases due to on-site welding work and welding quality is not constant depending on the welding skill of the worker. For example, when welding is performed with the two members 10 and 20 facing each other, if the flatness between the two members does not match, a gap may occur between the two members, so that welding cannot be performed properly.

In addition, since the existing support frame 30 for built-up construction of a steel curtain wall is manufactured by welding a pair of vertical members 10 and a plurality of horizontal members 20 one by one on site, the total construction period is extended, and when welding quality is deteriorated due to poor welding, there is a problem in that the risk of safety accidents due to construction increases.

2 to 4, the support frame 100 for constructing a steel curtain wall according to the present invention is a frame structure installed on-site in the horizontal and vertical directions of a building so that a plurality of glass panel assemblies can be attached to form the outer wall of the building as an outer wall panel having an exterior function such as glass. A second vertical member 120 disposed at opposite positions and having a cross-sectional shape of a "c" shape, having a pair of protruding ends 122 protruding outward on the outer surface thereof, and a plurality of horizontal members 130 coupled at regular intervals in the longitudinal direction between the first vertical member 110 and the second vertical member 120.

Specifically, the first vertical member 110 constituting one support frame 100 has a cross-sectional shape cut in the horizontal direction (left-right direction or horizontal direction) in a flat plate structure in the form of an “L” (line). In addition, the second vertical member 120 disposed in parallel with the first vertical member 110 at regular intervals has a pair of protruding ends 122 formed on the outside of the same flat plate structure as the first vertical member 110. As shown in FIG.

Here, the first vertical member 110 and the second vertical member 120 may be configured to have a certain curvature in the longitudinal direction (longitudinal direction). That is, when it is desired to make the outer surface of the building curved in order to enhance the aesthetics of the building, the first vertical member 110 and the second vertical member 120 may be configured in a curved shape having a certain curvature.

Here, the second vertical member 120 can be manufactured by fixing a pair of protruding ends 122 having a rectangular bar shape to the outer surface of the flat plate through welding and then post-processing the welded part.

Accordingly, when a pair of support frames 100 as described above are connected in the horizontal direction, as shown in FIGS. 5 and 6, the second vertical member 120 having a ‘c’-shaped cross section of the support frame 100 on one side (left side of the drawing) and the first vertical member 110 having an ‘L’ shaped cross section of the other side (right side of the drawing) support frame 100 are coupled to each other, and the combined vertical member (110, 120) can be formed as a vertical member (110, 120) structure having an excellent reinforcing structure of a substantially 'ㅁ'-shaped structure in which a space is formed in the cross-sectional shape of the portion.

Here, the meaning that the cross-sectional shape of the second vertical member 120 having the pair of protruding ends 122 is formed in a 'c'-shaped structure means that the cross-sectional shape of the second vertical member 120 has a 'c'-shaped structure as a whole due to the structure of the pair of protruding ends 122, and the cross-sectional shape of the second vertical member 120 is 'ㅑ' depending on the formation position of the protruding ends 122. It is also possible to form to have a cross-sectional structure of various shapes such as a ruler. Therefore, the 'c'-shaped cross-sectional structure of the second vertical member 120 mentioned in the present invention can be interpreted as meaning including all structures in which a space is formed between a pair of protruding ends 122. In addition, it goes without saying that additional protruding ends can be formed between the pair of protruding ends 122 as needed.

In this case, the lower region of the sleeve member 140 may be attached and fixed to the upper end of the second vertical member 120 by welding based on the longitudinal center of the sleeve member 140. That is, the pair of protruding ends 122 of the second vertical member 120 may be formed only at the lower portion of the lower region 140a to which the sleeve member 140 is fixed. Alternatively, in some cases, it is also possible to form a structure in which the lower region 140a of the sleeve member 140 is located inside the protruding ends 122 on both sides of the upper region of the second vertical member 120 and is attached and fixed.

In addition, the thickness of the sleeve member 140 is formed to have a thickness width corresponding to the thickness width (protrusion width) of the protruding end, so that the sleeve member 140 is fixed to the upper end of the second vertical member 120, the outer surface of the sleeve member 140 may be configured to be located on the same plane as the outer surface of the protruding end 122 located thereunder.

In addition, a plurality of fastening holes 142 for fastening socket bolts SB and socket nuts SN are formed in the sleeve member 140, including the first vertical member 110 and the second vertical member 120, so that a plurality of support frames can be connected and bound to each other in the horizontal and vertical directions using socket bolts SB and socket nuts SN, which will be described later.

In the lower part, the upper horizontal profile 220 has a structure in which the upper horizontal profile 220 is fixed to the fastening part 164 of the bracket 160 for the horizontal member by the bolt 165 and the nut 166, while in the lower part, the lower horizontal profile 220 is engaged with the supporting part 162 of the bracket 160 for the horizontal member. It is possible to form a stable support structure and a fixing structure at a specific location on the front side of the front side, so that a more robust and stable support structure of the glass panel assembly 200 can be provided.

On the other hand, Figures 13 and 14 show one construction example of constructing a steel curtain wall using the support frame 100 for constructing a steel curtain wall of the present invention having the above-described configuration.

First, FIG. 13 shows a construction example in which a plurality of support frames are sequentially constructed in the longitudinal direction of a building. As shown in FIG. 13, 1 unit of the support frame 100 prefabricated at the factory in the form of a unit is first fixed to the lower anchor 310 part fixed to the floor surface (D) of the building, and then another 2 units and 3 units of another support frame are placed on the upper part of 1 unit of the support frame 100 to the second vertical part of each support frame. Using the sleeve member 140 fixed to the upper part of the material 120, it is connected sequentially through the process of fastening with socket bolts (SB) and socket nuts (SN), and finally, the 3 units of the support frame placed at the top are fixed to the upper anchor 320 fixed to the girder (G) part to complete the construction of one column.

After the construction of one row using the support frame 100 is completed as described above, as shown in FIG. 14, 4 units, which are the lowermost support frames 100 in the two rows, are fixed to the lower anchor 310 in the same way as the 1 unit, and between the second vertical member 120 of 1 unit and the first vertical member 110 of 4 units adjacent to each other in the horizontal direction, a socket bolt (SB) and a socket nut (SN) are used. In addition, the second vertical member 120 of 1 unit and the first vertical member 110 of 4 units, which are connected to the sleeve member 140 at the upper end, are also tightened and fixed in the same way using socket bolts (SB) and socket nuts (SN).

Next, 5 Units and 6 Units of another support frame on top of 4 Units of the support frame 100 are sequentially fastened with socket bolts (SB) and socket nuts (SN) using the sleeve member 140 fixed to the top of the second vertical member 120 of each support frame 100, and then fasten between 2 Units and 5 Units, and 3 Units and 6 Units with a plurality of socket bolts (SB) and socket nuts (SN), and finally the top 2-row construction is completed through the work of fixing the 6 units placed on the stage to the upper anchor 320.

In the above manner, through a simple operation of sequentially connecting a plurality of support frames 100 in the vertical and horizontal directions of the building using socket bolts (SB) and socket nuts (SN), the glass panel assembly 200 is attached. Construction of the support frame structure, which becomes the skeleton, can be completed.

In addition, among the plurality of support frames connected to the outer wall of the building in the horizontal and vertical directions as described above, the support frames connected in the horizontal direction at the lowermost end of the outer wall of the building may be fixed to the floor surface through the plurality of lower anchors 310.

In FIGS. 15 and 16, when constructing 1 row and 2 rows using the support frame as in FIGS. 13 and 14 described above, 1 Unit and 4 Units disposed at the bottom are fixed to the floor surface through the lower anchor 310. It shows a specific state.

As shown in FIGS. 15 and 16, 1 Unit and 4 Units of the support frame 100 disposed at the bottom in the first and second row construction are attached to one lower anchor 310 fixed to the floor. It can be fixed at the same time.

Specifically, the lower anchor 310 includes a base plate 312 installed on the bottom surface of the outer wall of the building and a pair of fixing members 314 vertically fixed to the upper surface of the base plate 312 at regular intervals. Here, the base plate 312 is fixed on the bottom surface D through fastening of anchor bolts and nuts in a state adjusted to a designed height level from the bottom surface.

In addition, the lower end of the second vertical member 120 of 1 unit and the lower end of the first vertical member 110 of 4 units among the horizontally neighboring support frame 100 1 Unit and 4 Units are inserted between a pair of fixing members 314 and coupled using high tension bolts (SB) and nuts (SN) while in contact with each other, and the final combination is shown in FIG. At this time, the contact area between the 1 Unit and 4 Unit and the lower anchor 310 may be permanently bound by performing additional welding.

In addition, FIG. 17 illustrates a state in which each support frame constructed adjacently in the horizontal and vertical directions is coupled through the sleeve member 140 in the construction process of the support frame 100 as shown in FIGS. 13 and 14 described above.

As shown in FIG. 17, 1 Unit and 4 Units of the lowermost support frame 100 are coupled through the lower region of the sleeve member 140 attached to the upper end of the second vertical member 120 of 1 Uni, and the position of the hole formed in each unit and the sleeve in the state where the second vertical member 120 of 1 Unit and the first vertical member 110 of 4 Units are in contact with each other in the lower region of the sleeve member 140. The positions of the holes formed in the member 140 may be matched and bound using eight socket bolts (SB) and socket nuts (SN). And, in the upper region of the sleeve member 140, the 2 units and 5 units located on the upper side of the 1 unit and 4 units can be bound using eight socket bolts (SB) and socket nuts (SN) in the same manner in a state of facing each other. In this way, 1 Unit and 4 Units are bound on the left and right sides of the lower region of one sleeve member 140, and 2 Units and 5 Units are completed on the left and right sides of the upper region, as shown in FIG. 17(c).

In addition, in FIGS. 18 and 19, the state in which the uppermost support frame is coupled to the upper anchor 320 in the construction process of the first and second rows of the support frames shown in FIGS. 13 and 14 described above is illustrated.

As shown in FIGS. 18 and 19, 3 Units and 6 Units of the support frame 100 disposed at the top in the construction of the first and second rows of the support frame are one upper anchor fixed to the front surface of the girder. It can be fixed to the part of 320 at the same time.

Specifically, the upper anchor 320 includes a base plate 322 fixed to the front surface of the girder G forming the upper frame structure and one fixing member 324 fixed to the front side of the base plate 322 in a vertically protruding form. Here, the base plate 322 is fixed to the front surface of the girder (G) by fastening bolts and nuts in a state adjusted to the designed height level from the front surface of the girder (G) using level bolts (328).

In addition, in a state where the upper end of the second vertical member 120 of 3 units and the upper end of the first vertical member 110 of 6 units are in contact with both sides of the fixing member 324, the high tension bolt (SB) and the nut (SN) are fastened and combined together, and the final combination is shown in FIG. 19. At this time, the contact area between the 3 units and 6 units and the upper anchor 320 may be permanently bound by performing additional welding.

As described above, the present invention divides the existing vertical member having a 'C'-shaped cross-sectional shape in the support frame into a first vertical member 110 having an 'I'-shaped cross-sectional shape and a second vertical member 120 having a 'C'-shaped cross-sectional shape, and the construction is performed by fastening with bolts and nuts at the site. There is an advantage that the construction of the steel curtain wall is very simple, the workability is improved, and the construction period can be shortened /

In particular, in the past, since a support frame for curtain wall construction is manufactured by welding a vertical member having a 'C'-shaped cross-sectional shape manufactured in a factory with a horizontal member at the site, it is difficult to perform an elaborate welding operation between the vertical member and the horizontal member, and the labor cost due to the on-site welding work and the welding quality are not constant depending on the welding skill level of the worker. However, the present invention has an "L"-shaped first vertical member 110 and a "c"-shaped second vertical member Since the support frame 100 is pre-fabricated in a factory in the form of a single unit, construction is performed through a simple operation of fastening it with bolts (SB) and nuts (SN) in the field. Compared to the construction method by conventional field welding, the construction period can be greatly shortened, the increase in labor costs due to field welding can be suppressed, and the construction quality can always be maintained stably.

In addition, the present invention is a method of unitizing the support frame with a unit standard of 1 span that meets the design specifications, and since it is pre-manufactured as a finished product at the factory and delivered to the site for construction, it is easy to manage the dimensions of the non-standard (support frame curved shape), overcome the difficulties of building facilities for manufacturing existing support frames, and have the advantage of being efficient in preventing safety accidents and saving time compared to on-site construction by the existing knockdown method.

In addition, in the past, when deformation (torsion, fullness) of the member due to welding occurs during the manufacturing process of the vertical member, there was a problem that the horizontal member could not be fastened to the vertical member by welding. It has the advantage of improving the construction quality as no welding deformation occurs.

In addition, the existing method has the disadvantage that when the glass panel assembly is fixed to the horizontal member, a reinforcing member is added to the horizontal member to prevent deformation and sagging of the horizontal member, so that the appearance is not beautiful. However, the present invention has a 'T'-shaped longitudinal section. Since the horizontal member having a structure is welded between both vertical members and then installed in a painted state, the appearance is more beautiful than the prior art.

In addition, since the present invention is produced in the factory and delivered to the site as a unit unit support frame in which the horizontal member is welded to the vertical member, and the support frame can be minimized in the process of producing, transporting, and installing support frames, and in addition, the support frame weight material that exceeds 110kg per one as before, as in the field, It has the advantage of significantly reducing the possibility of safety accidents, such as the risk of falling weights that may occur when the conclusion is made.

In addition, the existing method is structurally unfavorable because the wind load and dead load of the horizontal profile constituting the glass panel assembly is not transmitted to the steel frame, and in addition, the existing vertical member is a unit structure method in which male + female are coupled to each other with an insertion space of about 18 mm. It moves at right angles to the direction of gravity in the slope (forward slope and reverse slope) section, and it is difficult to install (anchoring member sags and interferes during coupling). Since the present invention fixes the glass panel assembly with a glass press and moves it to an assembly position, lowering it from the top to the bottom, and fastening with a clip coupling method between the first fixing bracket and the second fixing bracket, the installation of the glass panel assembly is very easy, and the wind load and dead load are transmitted from the glass panel assembly to the vertical member of the support frame. The stress transmission is evenly distributed to the upper, middle, and lower three points of the vertical member where the second fixing bracket is installed. Since a structurally stable stress transfer structure can be formed and the work of assembling the glass panel assembly to the support frame can be performed very simply in a short time, there is an advantage in that workability is improved and construction time is shortened.

The scope of the present invention will be defined by the claims, but all changes or modifications derived from the configurations directly derived from the claims description as well as equivalent configurations thereof are also included in the scope of the present invention. It should be construed.
