Description

CROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims priority and benefits of Chinese Patent Application No. 201010104259.2, filed with State Intellectual Property Office, P. R. C. on January 29, 2010, the entire content of which is incorporated herein by reference.

FIELD

[0002] Embodiments of the present disclosure generally relate to a building and a method for constructing the same, more particularly, to a spatial light steel frame concrete building and a method for constructing the same.

BACKGROUND

[0003] In the field of construction technology, a concrete structure may apply to not only a low-rise and multistorey building, but also a high-rise building, and consequently has been widely used.

[0004] For a cast-in-situ concrete structure, reinforcing steel bars may need to be assembled in situ, and formworks may need to be mounted or removed in situ, which may cause heavy in-situ labor and long construction period.

[0005] A pre-cast reinforced concrete shear wall structure is that components are produced in a factory and assembled in situ. However, in order to solve problems of integral connection between pre-cast components and water seepage at a joint between pre-cast components, the construction cost may be high.

[0006] A Chinese Patent application (Publishing No. CN1958984A) discloses a steel mesh frame concrete composite building and a method for constructing the same, in which a cold-formed thin-walled steel is used to make a steel skeleton, and a conventional wood or steel formwork is replaced by a steel mesh. A steel mesh skeleton is made in a factory and assembled into a steel mesh frame in situ, and then concrete is cast in situ to form a concrete seismic wall structure. However, this structure still has the following defects.

[0007] Firstly, a trellis profile steel used in the steel mesh frame is a cold-formed trellis profile steel component with a thickness of 1.0mm to 4.0mm and a C-shaped, U-shaped or Z-shaped cross section, holes are formed and arranged uniformly in a web member between two wing edges parallel to each other, a reinforcing hemming is formed on a periphery of each hole, and the reinforcing hemming between two adjacent holes forms a U-shaped web member. The production process of this trellis profile steel is relatively complicated, holes need to be formed in a thin steel sheet by a punch, and then bending is performed on a cold-formed device. Depending on different porosities, based on the total weight of the trellis profile steel, the amount of crap steel sheets may be about 10wt% to about 15wt%, which may cause waste. Moreover, a special trellis profile steel production line may need to be constructed, which may result in high investment and high production cost.

[0008] Secondly, the steel mesh used in the steel mesh frame is a fish scale mesh formed by cold forming a galvanized steel sheet with a thickness of 0.3mm to 0.6mm, convex strip-like ribs arranged parallel to each other and spaced apart from each other by a predetermined distance are formed on the fish scale mesh, and the steel mesh is fixed on the surface of the steel skeleton by the convex portions of the strip-like ribs. The steel mesh does not play a part in structure stress, but is merely used as a formwork, which may cause high construction cost and increase the steel amount of a building. After the concrete is cast, wet plastering may also need to be performed on the surface of the steel mesh to flatten the surface of the steel mesh, thus increasing working procedures and wasting labor.

[0009] Another Chinese Patent application (Publishing No. CN101654925A) discloses a spatial solid mold truss concrete building and a method for constructing the same. However, in the method, non-removal formworks are used, and consequently may not be reused, which may increase the construction cost. In addition, because the formworks may not be removed, the density of the concrete after cast may not be detected conveniently.

[0019] The spatial light steel frame concrete building according to an embodiment of the present disclosure will be described below with reference to the drawings.

[0020] As shown in Figs. 1-5, the spatial light steel frame concrete building according to an embodiment of the present disclosure comprises a wall spatial light steel frame 1, a floor slab spatial light steel frame 2 and concrete.

[0021] As shown in Fig. 3, the floor slab spatial light steel frame 2 is connected to the wall spatial light steel frame 1 to form a building unit spatial light steel frame. The concrete is poured in the building unit spatial light steel frame. It should be appreciated that removable formworks 3 are mounted onto the building unit spatial light steel frame before the concrete is poured, and the formworks 3 are selectively removed after the concrete is solidified, thus reusing the formworks 3.

[0022] It would be appreciated that the fact that "the formworks 3 are selectively removed after the concrete is solidified" means that whether the formworks 3 are removed may depend on requirements. For example, in one embodiment, the formwork 3 at an outer side of the wall spatial light steel frame 1 forming an outer wall of the spatial light steel frame concrete building may not be removed, but may be permanently reserved, and consequently an insulation board 8 may be attached to the formwork 3 at the outer side of the wall spatial light steel frame 1 forming the outer wall of the spatial light steel frame concrete building. That is, an insulation layer is disposed on the outer wall of the spatial light steel frame concrete building, thus enhancing the thermal insulation performance of the building. However, the formworks 3 under the floor slab spatial light steel frame 2 and the formworks 3 on the wall spatial light steel frame 1 which do not form the outer wall of the spatial light steel frame concrete building may be removed. Certainly, in another embodiment, all the formworks 3 may be removed.

[0023] Each of the wall spatial light steel frame 1 and the floor slab spatial light steel frame 2 comprises a welded mesh reinforcement 4 and a plurality of trellis profile steels 11, the plurality of trellis profile steels 11 are spaced apart from each other and each has a plurality of stretching holes 113, and the welded mesh reinforcement 4 is welded to the trellis profile steels 11 so as to connect the plurality of trellis profile steels 11 together.

[0024] Each trellis profile steel 11 comprises two wing edges 111 parallel to each other and a plurality of web members 112 connected between the two wing edges 111, the two wing edges 111 and the plurality of web members 112 are integrally formed, the plurality of stretching holes 113 are defined by the plurality of web members 112 between the two wing edges 111, and the plurality of web members 112 and the plurality of stretching holes 113 are formed by stretching the two wing edges 111.

[0025] With the spatial light steel frame concrete building according to an embodiment of the present disclosure, the wall spatial light steel frame 1 and the floor slab spatial light steel frame 2 are formed by welding the welded mesh reinforcement 4 and the plurality of trellis profile steels 11 together respectively, and the plurality of web members 112 and the plurality of stretching holes 113 are formed by stretching the two wing edges 111, such that the trellis profile steels 11 may be simple to manufacture, materials may be saved, and investments on production apparatuses, the labor cost and the construction cost may be reduced.

[0026] In some embodiments, the spatial light steel frame concrete building may be a multistorey building, as shown in Fig. 2. As an example, an eight-storey building is shown. Each storey of the spatial light steel frame concrete building is formed by one storey of integral building unit, and each integral building unit is formed by horizontally arranging one or more building units. For example, in the embodiment shown in Figs. 1-2, one integral building unit is formed by 10 building units.

[0027] Each building unit is formed by pouring the concrete in one building unit spatial light steel frame formed by one wall spatial light steel frame 1 and one floor slab spatial light steel frame 2, and a plurality of integral building units are sequentially stacked upwardly to form the multistorey spatial light steel frame concrete building, in which the wall spatial light steel frame 1 of an upper storey of integral building unit is fixed on the wall spatial light steel frame 1 of a lower storey of integral building unit adjacent thereto. For example, the wall spatial light steel frame 1 of the upper storey of integral building unit may be connected to the wall spatial light steel frame 1 of the lower storey of integral building unit adjacent thereto by a connection member. A lower end of the wall spatial light steel frame 1 of a bottom storey of integral building unit is fixed on a foundation 13. An upper end of the wall spatial light steel frame 1 of a top storey of integral building unit is connected to the floor slab spatial light steel frame 2 as a roof.

[0028] In some embodiments, the floor slab spatial light steel frame 2 may be connected to the wall spatial light steel frame 1 by welding to form the building unit spatial light steel frame. Alternatively, the floor slab spatial light steel frame 2 may be connected to the wall spatial light steel frame 1 by a connection member.

[0029] In an alternative embodiment, as mentioned above, the formwork 3 may be permanently disposed onto the outer side of the wall spatial light steel frame 1 forming the outer wall of the spatial light steel frame concrete building. In other words, after the concrete is solidified, the formwork 3 at the outer side of the wall spatial light steel frame 1 forming the outer wall of the spatial light steel frame concrete building may not be removed, and the insulation board 8 may be attached to the formwork 3, thus enhancing the thermal insulation effect of the building.

[0030] In one example, as shown in Fig. 4, for example, each trellis profile steel 11 in the wall spatial light steel frame 1 and the floor slab spatial light steel frame 2 may be formed by using one steel sheet, forming a plurality of slits extended between the two wing edges 111 in a longitudinal direction (i.e., a left and right direction in Fig. 4) of the two wing edges 111 and then stretching the two wing edges 111 in a transversal direction (i.e., an up and down direction in Fig. 4) of the two wing edges 111, such that the plurality of web members 112 and the plurality of stretching holes 113 defined by the plurality of web members 112 are formed between the two wing edges 111. Therefore, the trellis profile steels 11 may be very simple to process, materials may be saved, and the time and the effort may be reduced.

[0031] It would be appreciated that the structure of the wall spatial light steel frame 1 is substantially the same as the structure of the floor slab spatial light steel frame 2, except that: before the concrete is poured, removable formworks 3 are mounted onto two sides of the wall spatial light steel frame 1, while removable formworks 3 are merely mounted onto a bottom surface of the floor slab spatial light steel frame 2.

[0032] In some embodiments, a window and a door of the building may be designed according to practical requirements. For this reason, a door opening and a window opening are reserved in portions of the wall spatial light steel frame 1 respectively so as to form the window and the door of the building respectively. A plurality of edge members 6 are disposed at two sides of the door opening and the window opening which are reserved in portions of the wall spatial light steel frame 1 in a horizontal direction respectively. Each edge member 6 comprises longitudinal reinforcing steel bars and horizontal stirrups or comprises vertical reinforcing steel bars, vertical profile steels and horizontal stirrups. In addition, a plurality of connection beams 7 are disposed above the door opening and the window opening. Each connection beam 7 comprises horizontal reinforcing steel bars and vertical stirrups. A stairwell opening may be previously formed in the floor slab spatial light steel frame 2 according to design requirements.

[0033] As shown in Fig. 5, the welded mesh reinforcement 4 may be formed by welding reinforcing steel bars 41 arranged horizontally and reinforcing steel bars 41 arranged vertically. The welded mesh reinforcement 4 is welded to the plurality of trellis profile steels 11, which are spaced apart from each other and each having a plurality of stretching holes 113, to form the wall spatial light steel frame 1 and the floor slab spatial light steel frame 2 respectively.

[0034] In some embodiments, the insulation board 8 disposed on the outer wall of the spatial light steel frame concrete building may be a composite insulation board. As shown in Fig. 6, the insulation board 8 comprises a polybenzene or rockwool insulation layer 801, an anti-crack mortar or board protection layer 802 and a decoration surface layer 803 from inside to outside.

[0035] The method for constructing the spatial light steel frame concrete building according to an embodiment of the present disclosure will be described below with reference to Fig. 7. The method for constructing the spatial light steel frame concrete building according to an embodiment of the present disclosure comprises steps of:

Each integral building unit may be formed by horizontally arranging one or more building units, each building unit is formed by pouring the concrete in one building unit spatial light steel frame formed by one wall spatial light steel frame 1 and one floor slab spatial light steel frame 2, and a plurality of integral building units are sequentially stacked upwardly to form the multistorey spatial light steel frame concrete building. The floor slab spatial light steel frame 2 may be connected to the wall spatial light steel frame 1 by welding or by a connection member.

[0037] As mentioned above, each trellis profile steel 11 is formed by forming a plurality of slits extended between the two wing edges 111 in a longitudinal direction of the two wing edges 111 and then stretching the two wing edges 111 in a transversal direction of the two wing edges 111.

[0038] In one embodiment, the method for constructing the spatial light steel frame concrete building further comprises: disposing an insulation board 8 on an outer wall of the spatial light steel frame concrete building, in which the formwork 3 at an outer side of the wall spatial light steel frame 1 forming the outer wall of the spatial light steel frame concrete building is permanently reserved, and the insulation board 8 is attached to the formwork 3 at the outer side of the wall spatial light steel frame 1 forming the outer wall of the spatial light steel frame concrete building.
