Description

Technical Field

[0001] The present invention relates to a steel structure building shell capable of erecting a scaffold and a scaffold erection method thereof, and more particularly to an invention in which a transverse aluminum extrusion is arranged between floors of the steel structure building shell, and the scaffold is fixed to the transverse aluminum extrusion by a two-stage fixing method, so that the outer wall can be assembled on the scaffold without adopting a high-altitude hanging operation. Background Art

[0002] Early residential buildings in Taiwan were mainly brick buildings. After reinforced concrete technology was introduced to Taiwan and the cost was reduced, residential buildings were changed to be mainly reinforced concrete. Later, with the economic development and high population density in Taiwan, the demand for super high-rise buildings with steel structures increased due to high land costs. Not only in commercial buildings, but also in residential buildings, there are more and more super high-rise buildings with steel structures. Among them, according to statistics, residential buildings in Taiwan account for more than 90% and are the bulk of the construction industry.

[0003] In general, Taiwan's buildings include three structural systems: RC structure (reinforced concrete), SS structure (steel frame structure) and SRC structure (steel frame reinforced concrete). Compared with traditional RC structure (reinforced concrete), SS structure (steel frame structure) or SRC structure (steel frame reinforced concrete) has the environmental characteristics of long life and recyclable materials, but the construction cost of SS structure (steel frame structure) or SRC structure (steel frame reinforced concrete) is high, so residential buildings are still mainly RC structure (reinforced concrete).

[0004] In RC (reinforced concrete) buildings, scaffolding is set up so that construction workers can complete the building structure on high floors. The scaffolding is set up by pre-embedded steel bars (such as three-point bamboo steel bars) on the RC beams of the building structure. The distance between adjacent pre-embedded steel bars is about 160 cm to 180 cm (adjusted according to the scaffolding erection diagram), and the pre-embedded steel bars are wrapped around the scaffolding to fix the scaffolding on the outside of the building structure. When the scaffolding is set up with pre-embedded steel bars, position errors are allowed and do not affect subsequent construction, so the scaffolding can be set up quickly.

[0005] In steel structure buildings such as SS structure (steel frame structure) or SRC structure (steel frame reinforced concrete), curtain walls are mostly used for the exterior walls. Curtain walls have the advantages of light weight, modular units, and fast construction and assembly. The assembly method is to hang the curtain wall outside the building floor through combined components.

[0006] However, the embedded steel bars used to fix the scaffolding in the building structure will hinder the assembly of the curtain wall, so the curtain wall cannot be assembled by setting up the scaffolding. At present, the curtain wall is assembled by high-altitude hanging operations, but the high-altitude hanging operations require high operating costs such as hanging tools and professionals, which further increases the cost of steel structure buildings and is not conducive to the promotion of steel structure buildings. Summary of the invention

[0007] In order to reduce the construction cost of steel structure residential buildings, the inventor has proposed Taiwan Patent Application No. 111147640 "Structure of Steel Structure Building Shell". In order to further facilitate the erection of scaffolding in steel structure buildings, and to assemble exterior walls (such as curtain walls) on the scaffolding, the purpose of the present invention is to provide a steel structure building shell that can be scaffolded and a scaffolding erection method.

[0008] The present invention provides a steel structure building shell capable of erecting a scaffold, which is used for two-stage fixed scaffolding, and comprises:

[0009] The main body of the steel structure building comprises an H steel beam and a DECK steel floor slab, wherein the DECK steel floor slab is assembled on the H steel beam.

[0010] The building floor comprises a RC floor slab laid on the DECK steel-supported floor slab, and the DECK steel-supported floor slab and the RC floor slab serve as the building floor slab, a steel bar structure and embedded steel bars are laid in the RC floor slab, and the embedded steel bars extend out of the RC floor slab and are connected around the scaffolding to serve as the first stage of fixing of the scaffolding.

[0011] The building exterior wall includes: embedding parts for locking wall connecting rods into the RC floor slabs at intervals. A transverse aluminum extrusion is arranged on the outside of the RC floor slab. One end of the wall connecting rod passes through the transverse aluminum extrusion and is locked on the embedding part, and the other end of the wall connecting rod is locked on the scaffolding, and then the embedded steel bars are removed from the scaffolding to serve as the second stage of fixing of the scaffolding. The exterior wall panels are installed between the building floor slabs from the outside, and the adjacent exterior wall panels are separated by the transverse aluminum extrusion.

[0012] When the exterior wall of the building is completed, the wall connecting rods are dismantled one by one to remove the scaffolding.

[0013] The present invention also provides a method for erecting a scaffold for a steel structure building, comprising the following steps:

[0014] Constructing the main body of the steel structure building: erecting the H steel beams and the DECK steel floor slabs of the main body of the steel structure building, and assembling the DECK steel floor slabs on the H steel beams.

[0015] Construction of building floor: The RC floor is laid on the DECK steel-supported floor, and the DECK steel-supported floor and the RC floor serve as the building floor. The RC floor is laid with a steel bar structure and embedded steel bars. The embedded steel bars extend out of the RC floor and are connected around the scaffolding to serve as the first stage of fixing the scaffolding.

[0016] Construction of building exterior walls: embedding parts for locking wall connecting rods into the RC floor slabs at intervals, and arranging transverse aluminum extrusions on the outer side of the RC floor slabs, and then passing one end of the wall connecting rod through the transverse aluminum extrusions and locking it on the embedding parts, and locking the other end of the wall connecting rod to the scaffolding, and then removing the embedded steel bars from the scaffolding as the second stage of fixing the scaffolding; installing the exterior wall panels between the building floor slabs from the outside, and separating the adjacent exterior wall panels by the transverse aluminum extrusions.

[0017] When the exterior wall of the building is completed, the wall connecting rods are dismantled one by one to remove the scaffolding.

[0018] Furthermore, the embedded steel bars are made of three-part bamboo-joint steel bars, and the three-part bamboo-joint steel bars are used to wrap the scaffolding at least three and a half turns to meet the fixing strength specified by regulations.

[0019] Furthermore, after the embedded steel bars are removed from the scaffolding, the portion of the embedded steel bars exposed from the RC floor slab is cut off.

[0020] Furthermore, the embedded part is an expansion nut, and one end of the wall connecting rod is screwed to the expansion nut.

[0021] Furthermore, after the wall connecting rod is disassembled, the embedded part is locked with a nut, or filled with silicone and then sealed with paint.

[0022] The following effects can be achieved according to the above technical features:

[0023] 1. The scaffolding is fixed to the horizontal aluminum extrusion in a two-stage fixing method, so that the curtain wall can be assembled on the scaffolding without the need for high-altitude hanging operations, which can reduce the cost of steel structure buildings, is conducive to the promotion of steel structure buildings, and prolongs the life of buildings and meets environmental protection requirements.

[0024] 2. The first stage of fixing of the scaffold of the present invention uses embedded steel bars to wrap and fix, which can quickly complete the erection of the scaffold; the second stage of fixing the scaffold uses wall connecting rods to replace the embedded steel bars one by one. In addition to enabling the curtain wall to be assembled on the scaffold, the wall connecting rods are accurately positioned, making the scaffold more firmly erected and improving safety.

DETAILED DESCRIPTION

[0032] The following embodiments are only for the purpose of explaining the steel structure building shell and the scaffolding erection method of the present invention, and are not intended to limit the present invention. Due to the large size of the steel structure building shell, the drawings are partial schematic diagrams to clearly show the features of the present invention.

[0033] The steel structure building shell of the embodiment of the present invention includes a steel structure building body, a building floor and a building exterior wall.

[0034] See also Figure 1 and Figure 2 As shown, firstly, a steel structure building body A is constructed. The steel structure building body A mainly includes an H steel beam 1 and a DECK steel floor slab 2. The DECK steel floor slab 2 is assembled on the H steel beam 1.

[0035] After the main body A of the steel structure building is assembled, the building floor B is constructed, and the RC floor 3 is laid on the DECK steel floor 2, and the DECK steel floor 2 and the RC floor 3 serve as the building floor B. A steel bar structure 31 and embedded steel bars are laid in the RC floor 3. The embedded steel bars in this embodiment use three-part bamboo-joint steel bars 32, which extend out of the RC floor 3 and are wrapped around the scaffolding 4 as the first stage of fixing the scaffolding 4. To ensure that the scaffolding 4 is stable and meets the fixing strength specified by laws and regulations, the three-part bamboo-joint steel bars 32 are wrapped around the scaffolding 4 for at least three and a half turns. When the embedded steel bars use other steel bars such as four-part bamboo-joint steel bars, the scaffolding 4 is wrapped according to relevant specifications.

[0036] See also Figure 3 and Figure 4 As shown, after the construction of the building floor B is completed and the scaffolding 4 is set up for the first stage of fixing, the construction of the building exterior wall C can be carried out. The building exterior wall C of this embodiment is a double-layer structure. First, the RC water stop pier 5 is cast on the RC floor 3, and then the embedded parts 7 for locking the wall connecting rod 6 are embedded in the RC floor 3 at intervals, and a transverse aluminum extrusion 8 is set on the outside of the RC floor 3, and then one end of the wall connecting rod 6 passes through the transverse aluminum extrusion 8 and is locked in the embedded part 7. The embedded part 7 of this embodiment uses an expansion nut, and the wall connecting rod 6 is screwed on the embedded part 7. It has been tested that it can bear a load of 2 tons. Then the other end of the wall connecting rod 6 is locked to the scaffolding 4, and then the three-part bamboo-jointed steel bar 32 is removed from the scaffolding 4 as the second stage of fixing the scaffolding 4. After the three-part bamboo-jointed steel bar 32 is removed from the scaffolding 4, the part of the three-part bamboo-jointed steel bar 32 exposed in the RC floor 3 can be cut off.

[0037] Then, one of the two C-shaped steels 9 is arranged on the RC water stop pier 5 with the opening facing upward, and the other is arranged on the DECK steel bearing floor slab 2 with the opening facing downward. Further, the outer wall panel 101 and the inner wall panel 102 are attached to the opposite sides of the RC water stop pier 5 and the two C-shaped steels 9, and a hollow space S is formed between the outer wall panel 101 and the inner wall panel 102, thereby making the building outer wall C a double-layer structure, and making the building outer wall C directly arranged on the building floor slab B, so that the building floor slab B can completely separate the upper / lower floor space, and become a good water-proof / soundproof / heat-insulating layer between the upper / lower floors, wherein the outer wall panel 101 is installed between the building floor slabs B from the outside, and the adjacent outer wall panels 101 are separated by the transverse aluminum extrusion 8, and the assembly gap of the outer wall panel 101 can be further filled with elastic cement to improve the waterproof effect between the indoor and outdoor sides. In this embodiment, the sound insulation material 20 is respectively arranged on the two C-shaped steels 9 and filled in the hollow space S. The sound insulation material 20 extends along the height direction of the building outer wall C. For example, the hollow space S is filled with rock wool. The sound insulation material 20 further fills the hollow space S in the double-layer structure of the building outer wall C, so that the sound insulation / heat insulation effect between the indoor and outdoor sides is better. Then, silicone 30 is filled between the transverse aluminum extrusion 8 and the above-mentioned two outer wall panels 101. Compared with the traditional one-piece curtain wall that is easily damaged due to resonance when subjected to force and vibration, the present invention can divide the outer wall panel 101 through the transverse aluminum extrusion 8, which can reduce the risk of force damage to the outer wall panel 101. In addition, the building outer wall C uses the transverse aluminum extrusion 8 to rationally fill the seams at the floor joints. The number of silicone 30 is small, so maintenance is better and cost is less.

[0038] See also Figure 5 and Figure 6 As shown, when the building exterior wall C is completed, the wall connecting rods 6 are dismantled one by one and the scaffolding 4 is removed (the wall connecting rods 6 and the scaffolding 4 are shown in FIG. Figure 3 , Figure 4 ), after the wall connecting rod 6 is removed, the nut 40 is locked on the embedded part 7, or the silicone is filled and then sealed with paint. In this way, the exterior wall panel 101 of the present invention is flat and does not need to be attached with tiles. Therefore, after the exterior wall panel 101 is sprayed with a waterproof layer throughout the building, a natural paint can be further applied to complete the construction of the building exterior wall C.
