Definitions

  • 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.
  • 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.
  • 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.
  • a pre-cast reinforced concrete shear wall structure is that components are produced in a factory and assembled in situ.
  • the construction cost may be high.
  • 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.
  • this structure still has the following defects.
  • 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.
  • the amount of crap steel sheets may be about 10wt% to about 15wt%, which may cause waste.
  • a special trellis profile steel production line may need to be constructed, which may result in high investment and high production cost.
  • 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.
  • Another Chinese Patent application (Publishing No. CN101654925A ) discloses a spatial solid mold truss concrete building and a method for constructing the same.
  • non-removal formworks are used, and consequently may not be reused, which may increase the construction cost.
  • the formworks may not be removed, the density of the concrete after cast may not be detected conveniently.
  • Embodiments of the present disclosure seek to solve at least one of the problems existing in the prior art to at least some extent. Accordingly, a spatial light steel frame concrete building is provided.
  • the frame of the spatial light steel frame concrete building may be simple to process, the labor cost and investments on apparatuses may be reduced, and steels may be saved. Furthermore, a method for constructing the spatial light steel frame concrete building is also provided.
  • a spatial light steel frame concrete building comprises: a wall spatial light steel frame; a floor slab spatial light steel frame connected to the wall spatial light steel frame to form a building unit spatial light steel frame; and concrete poured in the building unit spatial light steel frame, in which each of the wall spatial light steel frame and the floor slab spatial light steel frame comprises a welded mesh reinforcement and a plurality of trellis profile steels, the plurality of trellis profile steels are spaced apart from each other and each has a plurality of stretching holes, the welded mesh reinforcement is welded to the trellis profile steels so as to connect the plurality of trellis profile steels together, each trellis profile steel comprises two wing edges parallel to each other and a plurality of web members connected between the two wing edges, the two wing edges and the plurality of web members are integrally formed, the plurality of stretching holes are defined by the plurality of web members between the two wing
  • a method for constructing a spatial light steel frame concrete building comprises steps of:

Moreover, the formworks may be removed to be reused, thus further reducing the cost.
  • relative terms such as “central”, “longitudinal”, “lateral”, “front”, “rear”, “right”, “left”, “inner”, “outer”, “lower”, “upper”, “horizontal”, “vertical”, “above”, “below”, “up”, “top”, “bottom” as well as derivative thereof (e.g., “horizontally”, “downwardly”, “upwardly”, etc.) should be construed to refer to the orientation as then described or as shown in the drawings under discussion. These relative terms are for convenience of description and do not require that the present disclosure be constructed or operated in a particular orientation.
