Description

Technical Field

[0001] The present invention relates to a steel structure building constructed using a scaffold and a method for erecting the scaffold of the steel structure building. In particular, by arranging horizontal aluminum profiles between floors of the outer shell of the steel structure building and fixing the scaffold outside the horizontal aluminum profiles by two-stage fixing, it is possible to assemble the outer wall on the scaffold without the need for rope high-altitude work. The present invention relates to a steel structure building constructed using a scaffold and a method for erecting the scaffold of the steel structure building.

Background Art

[0002] In the early days of housing construction in Taiwan, brick construction was the mainstream. However, through the introduction of reinforced concrete technology and cost reduction, reinforced concrete has become the mainstay of housing construction. Subsequently, as the economy of Taiwan developed and the population density increased, the cost of land soared, and the demand for super high-rise buildings mainly made of steel structures increased. Not only commercial buildings but also high-rise residential buildings made of steel structures increased. According to statistics, in Taiwan, housing buildings account for more than 90% and most of the construction industry.

[0003] Generally, Taiwanese buildings include three structures: RC construction (reinforced concrete), SS construction (steel structure), and SRC construction (steel-reinforced concrete). The SS structure (steel structure) or SRC structure (steel-reinforced concrete) has a longer lifespan and recyclable materials and environmental protection characteristics compared to the conventional RC structure (reinforced concrete). However, due to the high construction cost of the SS structure (steel structure) or SRC structure (steel-reinforced concrete), housing buildings mainly still focus on the RC structure (reinforced concrete).

[0004] For an RC structure (reinforced concrete) building, by erecting a scaffold, construction workers can use the scaffold to work on high floors and complete the construction structure. The RC beam of the building structure has embedded steel bars (for example, D10 ribbed steel bars), and the distance between adjacent embedded steel bars is between about 160 cm and 180 cm (adjusted according to the scaffold erection drawing). By winding the embedded steel bars on the scaffold and fixing the scaffold to the outside of the building structure, the scaffold can be erected. When erecting the scaffold using the embedded steel bars, the position error is allowed and it will not affect the subsequent construction, so the erection of the scaffold can be completed quickly.

[0005] In steel structure buildings such as SS structures (steel frame structures) or SRC structures (steel frame reinforced concrete), many adopt curtain walls on the outer walls. The curtain wall is lightweight, presents a modular unit form, and has advantages such as quick installation during construction. Its installation method is to suspend the curtain wall outside the floor slab by connecting members.

[0006] However, since the embedded steel bars used for fixing the scaffold in the building structure interfere with the curtain wall assembly, the curtain wall cannot be assembled using the scaffold. Currently, the curtain wall is assembled by the rope high-altitude work method, but the costs of work such as the lifting tools and specialized workers required for rope high-altitude work are high, further pushing up the cost of the steel structure building, which is disadvantageous to the popularization of the steel structure building.

[0007] The applicant of the present application has previously applied for a "structure of the outer shell of a steel structure building" for suppressing the construction cost of a steel structure residential building as Taiwan Patent Application No. 111147640.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The problem to be solved by the present invention is to provide a steel structure building constructed using a scaffold and a method for erecting a scaffold of a steel structure building, which makes the scaffold erection of the steel structure building more convenient and enables the assembly of the outer wall (such as a curtain wall) on the scaffold.

Means for Solving the Problem

[0010] The formwork erection method for the steel frame structure building of the present invention is such that the steel frame structure building includes a steel frame structure building main body, a floor slab, and a building outer wall. The steel frame structure building main body includes H-shaped steel and a deck plate incorporated on the H-shaped steel. The floor slab includes an RC slab laid on the deck plate. The building outer wall includes an embedded member, a lateral aluminum profile, and an outer wall plate. The steps include incorporating the deck plate on the H-shaped steel and constructing the steel frame structure building main body; laying an RC slab on the deck plate to form the floor slab, laying a steel bar structure and embedded steel bars in the RC slab, extending the embedded steel bars outside the RC slab and winding them around the formwork, and as the first-stage fixing of the formwork, constructing the floor slab; embedding the embedded members used for screwing and fixing the wall connecting rods at intervals in the RC slab, installing lateral aluminum profiles outside the RC slab, then inserting one end of the wall connecting rod through the lateral aluminum profile and screwing and fixing it to the embedded member, screwing and fixing the other end of the wall connecting rod to the formwork, then removing the embedded steel bars from the formwork as the second-stage fixing of the formwork, installing the outer wall plate between the floor slabs from the outside, separating the adjacent outer wall plates by the lateral aluminum profiles, and constructing the building outer wall; and when the construction of the building outer wall is completed, removing the wall connecting rods and removing the formwork.

[0011] Furthermore, by using D10 ribbed steel bars as the embedded steel bars and winding the D10 ribbed steel bars around the formwork at least three and a half turns, the fixing strength specified by the regulations is satisfied.

[0012] Furthermore, remove the embedded steel bars from the formwork and cut the part of the embedded steel bars exposed from the RC slab.

[0013] Furthermore, the embedded member is an expansion nut, and one end of the wall connecting rod is screwed and fixed to the expansion nut with a screw.

[0014] Furthermore, after removing the wall connecting rod, screw a nut onto the embedding member or fill it with silicon and then level it with paint to seal it.

Advantages of the Invention

[0015] According to the present invention, based on the above technical features, the following effects can be achieved. 1. By fixing the scaffold to the outside of the horizontal aluminum profile in a two-stage manner and enabling the outer wall to be assembled on the scaffold, it is not necessary to perform rope high-altitude work, so the cost of steel structure buildings can be reduced, which is beneficial to the popularization of steel structure buildings. At the same time, the service life of the building can be extended, and the environmental protection requirements can be met. 2. In the first-stage fixing of the scaffold, by winding and fixing the embedded steel bars, the erection of the scaffold can be completed quickly. In the second-stage fixing of the scaffold, the wall connecting rod is used to replace the embedded steel bars, enabling the outer wall to be assembled on the scaffold. In addition, the position of the wall connecting rod can be accurately aligned, the scaffold can be erected more firmly, and the safety is improved.

Best Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Needless to say, the present invention is not limited to the embodiments. In addition, since the steel frame structure building is huge, all the drawings are partially shown in order to clearly show the features of the present invention.

[0018] In this embodiment, the steel frame structure building includes a steel frame structure building main body A, a floor slab B, and a building outer wall C.

[0019] As shown in FIGS. 1 and 2, first, the steel frame structure building main body A is constructed. The steel frame structure building main body A mainly includes a steel beam made of H-shaped steel 1 and a deck plate 2, and the deck plate 2 is incorporated on the H-shaped steel 1.

[0020] After the assembly of the steel frame structure building main body A is completed, the floor slab B is constructed. An RC slab 3 is laid on the deck plate 2 to form the floor slab B. A reinforcing bar structure 31 and embedded reinforcing bars are laid in the RC slab 3. In this embodiment, D10 ribbed bars 32 are used as the embedded reinforcing bars. The D10 ribbed bars 32 extend outside the RC slab 3, and the D10 ribbed bars 32 are wound around the scaffold 4 to perform the first-stage fixing of the scaffold 4. In order to ensure the stable fixing of the scaffold 4 and satisfy the fixing strength specified by the regulations, the D10 ribbed bars 32 are wound around the scaffold 4 at least three and a half turns. When other reinforcing bars such as D13 ribbed bars are used for the embedded reinforcing bars, they are wound around the scaffold 4 in accordance with the regulations of the relevant laws and regulations.

[0021] As shown in FIGS. 3 and 4, after the construction of the floor slab B is completed and the scaffold 4 is erected and the first-stage fixing is performed, the construction of the building outer wall C can be carried out. In this embodiment, the building outer wall C has a two-layer structure and includes an embedded member 7, a horizontal aluminum profile 8, an outer wall plate 101, and an inner wall plate 102.

[0022] To construct the building outer wall C, first, after pouring and molding the RC water stop edge 5 on the RC slab 3, a plurality of embedded members 7 used for fixing the wall connecting rod 6 are embedded into the RC slab 3 from the outer surface at intervals, and a horizontal aluminum section bar 8 is installed on the outside of the RC slab 3. Then, one end of the wall connecting rod 6 is inserted through the horizontal aluminum section bar 8 and screwed onto the embedded member 7.

[0023] In this embodiment, an expansion nut is used as the embedded member 7, and the wall connecting rod 6 is screwed and fixed to the embedded member 7 with a screw. According to tests, it can withstand a load of 2 tons. Furthermore, after screwing and fixing the other end of the wall connecting rod 6 to the scaffold 4, the D10 ribbed steel bar 32 is removed from the scaffold 4 for the second-stage fixing of the scaffold 4. After removing the D10 ribbed steel bar 32 from the scaffold 4, the portion of the D10 ribbed steel bar 32 exposed from the RC slab 3 can be cut.

[0024] Subsequently, one of the two C-shaped steels 9 is installed on the RC water stop edge 5 with the opening facing upward, and the other is installed under the deck plate 2 with the opening facing downward. Further, the outer wall plate 101 and the inner wall plate 102 are attached to the opposite side portions of the RC water stop edge 5 and the two C-shaped steels 9. A hollow space S is formed between the outer wall plate 101 and the inner wall plate 102, whereby the building outer wall C has a two-layer structure and can be directly installed on the floor slab B. The floor slab B completely separates the upper and lower floor spaces and serves as a good water-proof / sound-proof / heat-insulation layer between the upper and lower floors. The outer wall plate 101 is installed between the upper and lower floor slabs B from the outside, and the adjacent outer wall plates 101 are separated by the horizontal aluminum section bar 8. The elastic cement is further filled in the assembly gap of the outer wall plate 101, and the waterproof effect between the indoor side and the outdoor side can be further enhanced.

[0025] In this embodiment, the sound insulation material 20 is installed between two C-shaped steels 9, fills the hollow space S, and the sound insulation material 20 extends along the height direction of the building outer wall C. For example, by filling the hollow space S with rock wool and filling the hollow space S in the two-layer building outer wall C with the sound insulation material 20, the sound insulation / heat insulation effect between the indoor side and the outdoor side can be further enhanced. Furthermore, by filling silicon 30 between the horizontal aluminum profile 8 and the two outer wall plates 101, the drawback that the conventional integral curtain wall is likely to be damaged due to resonance when receiving force and vibrating is suppressed. The outer wall plate 101 is separated by the horizontal aluminum profile 8, the risk of the outer wall plate 101 being damaged when receiving force can be reduced, and since the building outer wall C physically fills the joint of the floors with the horizontal aluminum profile 8, the quantity of silicon 30 can be made less, it has excellent maintainability, and costs can be saved.

[0026] As shown in FIGS. 5 and 6, after the construction of the building outer wall C is completed, the wall connecting rod 6 is removed and the scaffold 4 is removed (refer to FIGS. 3 and 4 for the wall connecting rod 6 and the scaffold 4). After the wall connecting rod 6 is removed, a nut 40 is screwed onto the embedded member 7, or after filling with silicon, it is leveled with paint and sealed. Since the outer wall plate 101 is flat and there is no need to paste bricks, after finally spraying a waterproof layer on the entire outer wall plate 101, a natural paint can be further applied to complete the construction of the building outer wall C.

[0027] The specific erection process of the scaffold in this embodiment will be described below. Among them, the same or similar methods as those during the construction of the conventional steel structure building are known to those skilled in the art, so they are not shown in the figure, and the detailed description of the construction is omitted.

At the same time, the lifespan of the building can be extended, and the environmental protection requirements can be met.
