Description

[Technical field]

[0001] The present invention relates to a steel frame building constructed using scaffolding and a scaffolding erection method for a steel frame building, and in particular to a steel frame building constructed using scaffolding, which makes it possible to assemble exterior walls on the scaffolding without the need for rope work at height by arranging lateral aluminum profiles between stories of the outer shell of the steel frame building and fixing the scaffolding to the outside of the lateral aluminum profiles through two-stage fixing. [Background technology]

[0002] Early residential construction in Taiwan was dominated by brick, but with the introduction of reinforced concrete technology and reduced costs, residential construction began to be dominated by reinforced concrete. Subsequently, as Taiwan's economy developed and the population density increased, land costs soared, leading to an increased demand for steel-framed skyscrapers, and the number of steel-framed skyscrapers increased not only for commercial buildings but also for residential buildings. According to statistics, residential buildings account for the majority of the construction industry in Taiwan, at over 90%.

[0003] Generally speaking, Taiwanese architecture includes three types of structures: RC (reinforced concrete), SS (steel frame) and SRC (steel reinforced concrete). SS (steel frame) or SRC (steel reinforced concrete) structures have a longer lifespan than traditional RC (reinforced concrete) structures, and their materials are recyclable and environmentally friendly. However, the construction costs of SS (steel frame) or SRC (steel reinforced concrete) structures are high, so residential buildings are still mainly made of RC (reinforced concrete) structures.

[0004] For reinforced concrete (RC) buildings, scaffolding can be erected so that construction workers can use the scaffolding to work on the upper floors and complete the building structure. The RC beams of the building structure have embedded rebars (e.g. D10 bamboo joint rebars) and the distance between adjacent embedded rebars is between approximately 160cm and 180cm (adjusted according to the scaffolding erection drawings). The scaffolding can be erected by wrapping the embedded rebars around the scaffolding and fixing it to the outside of the building structure. When scaffolding is erected using embedded rebars, positional errors are tolerated and do not affect subsequent construction, allowing the erection of the scaffolding to be completed quickly.

[0005] Many steel-frame buildings, such as SS (steel frame) or SRC (steel reinforced concrete) structures, use curtain walls for their exterior walls. Curtain walls have the advantages of being lightweight, being in the form of modularized units, and being quick to install during construction. The installation method is to suspend the curtain wall from the outside of the floor slab using connecting members.

[0006] However, curtain walls cannot be assembled using scaffolding because the embedded rebars used to secure scaffolding in building structures get in the way of curtain wall assembly. Currently, curtain walls are assembled using a rope-work at height method, but the costs of the lifting equipment and specialized workers required for rope-work at height are high, which further increases the cost of steel-framed buildings and is detrimental to the spread of steel-framed buildings.

[0007] The applicant of the present application has previously filed Taiwan Patent Application No. 111147640 for a "Steel Frame Building Shell Structure" that reduces the construction costs of steel frame residential buildings. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the examples. Moreover, since a steel frame building is huge, the drawings are all partial in order to clearly show the features of the present invention.

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

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

[0020] After the assembly of the steel frame building 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, and in this embodiment, D10 bamboo joint reinforcing bars 32 are used as the embedded reinforcing bars. The D10 bamboo joint reinforcing bars 32 are extended outside the RC slab 3, and are wrapped around the scaffolding 4 to form the first stage of fixing the scaffolding 4. To ensure stable fixing of the scaffolding 4 and to meet the fixing strength stipulated by regulations, the D10 bamboo joint reinforcing bars 32 are wrapped around the scaffolding 4 at least three and a half times. When using other reinforcing bars, such as D13 bamboo joint reinforcing bars, for the embedded reinforcing bars, wrap them around the scaffolding 4 in accordance with the provisions of the relevant laws and regulations.

[0021] As shown in Figures 3 and 4, after the construction of the floor slab B is completed and the scaffolding 4 is erected to perform the first stage of fixation, the construction of the building exterior wall C can be carried out. In this embodiment, the building exterior wall C has a two-layer structure, and includes an embedded member 7, a horizontal aluminum profile 8, an exterior wall panel 101, and an interior wall panel 102.

[0022] To construct the building exterior wall C, first, the RC water stop edge 5 is poured onto the RC slab 3 to form it, and then a number of embedded members 7 used to secure the wall connecting rods 6 are embedded at intervals from the outer surface of the RC slab 3 to the inside. Also, a horizontal aluminum profile 8 is installed on the outside of the RC slab 3, and then one end of the wall connecting rod 6 is inserted through the horizontal aluminum profile 8 and screwed into 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 by a screw. According to a test, this can withstand a load of 2 tons. Furthermore, after the other end of the wall connecting rod 6 is screwed and fixed to the scaffolding 4, the D10 bamboo joint rebar 32 is removed from the scaffolding 4 to complete the second stage of fixing of the scaffolding 4. After removing the D10 bamboo joint rebar 32 from the scaffolding 4, the portion of the D10 bamboo joint rebar 32 exposed from the RC slab 3 can be cut off.

[0024] Next, one of the two C-shaped steels 9 is installed on the RC waterstop edge 5 with its opening facing upward, and the other is installed under the deck plate 2 with its opening facing downward, and then an exterior wall panel 101 and an interior wall panel 102 are affixed to the opposing sides of the RC waterstop edge 5 and the two C-shaped steels 9. A hollow space S is formed between the exterior wall panel 101 and the interior wall panel 102, which gives the building exterior wall C a two-layer structure and allows the building exterior wall C to be installed directly on the floor slab B. The floor slab B completely separates the spaces between the upper and lower floors and serves as an excellent water-proofing / sound-proofing / thermal-insulating layer between the upper and lower floors. The exterior wall panels 101 are installed from the outside between the floor slabs B of the upper and lower floors, and adjacent exterior wall panels 101 are separated by horizontal aluminum profiles 8. Elastic cement can be further filled into the assembled gaps between the exterior wall panels 101 to further improve the waterproofing effect between the inside and outside of the room.

[0025] In this embodiment, the sound-proofing material 20 is installed between two C-shaped steels 9, filling the hollow space S, and extending along the height direction of the building exterior wall C. For example, by filling the hollow space S with rock wool and filling the hollow space S in the building exterior wall C with the sound-proofing material 20, the sound-proofing / heat-insulating effect between the indoor side and the outdoor side can be further improved. Furthermore, by filling the gap between the horizontal aluminum profile 8 and the two exterior wall panels 101 with silicone 30, the drawback of conventional one-piece curtain walls that they are prone to damage due to resonance when vibrated under force is suppressed, and the horizontal aluminum profile 8 separates the exterior wall panels 101, reducing the risk of the exterior wall panels 101 being damaged under force. Furthermore, since the joints between the floors of the building exterior wall C are physically filled with the horizontal aluminum profile 8, the amount of silicone 30 can be reduced, resulting in excellent maintainability and cost savings.

[0026] As shown in Figures 5 and 6, when construction of the building exterior wall C is completed, the wall connecting rods 6 are removed and the scaffolding 4 is taken down (see Figures 3 and 4 for the wall connecting rods 6 and the scaffolding 4). After removing the wall connecting rods 6, the nuts 40 are screwed onto the embedded members 7, or the embedded members 7 are filled with silicone and then flattened and sealed with paint. Since the exterior wall panel 101 is flat and does not require bricks to be attached, a waterproof layer can be sprayed onto the entire exterior wall panel 101, and then a natural paint can be applied to complete the construction of the building exterior wall C.

[0027] The specific steps for erecting the scaffolding in this embodiment are described below. Among them, the methods that are the same as or similar to those used in the construction of conventional steel frame buildings are known to engineers in this field, so they are not shown in the figures, and detailed explanations of the construction are omitted.

[0028] In this way, the two-stage fixing method allows the scaffolding to be fixed onto the horizontal aluminum profiles and the curtain wall to be assembled on the scaffolding, eliminating the need for rope work at height. This reduces the cost of steel frame buildings, is beneficial for the promotion of steel frame buildings, extends the lifespan of buildings, and meets environmental protection requirements.
