Abstract
The invention belongs to the field of building engineering, relates to a construction technology of a building structure, and in particular relates to a close column structure technology which is realized by adopting the assembly-cast-in-situ construction method and used in a residential building with a shear wall system. The technology is suitable for multi-storied and small high-rise residential buildings with the shear wall systems and can also be used in shear wall structures of other industrial and civil buildings. An assembly-cast-in-situ type close column structure is constituted by arranging close columns (7) in a cavity of a prefabricated building hollow wall formwork (8) and connecting the close columns (7) with cast-in-situ corner posts (5), cast-in-situ beams (4), floor slabs (1) and other members. By adopting the assembly-cast-in-situ type close column structure with good performances, a traditional wall body formwork is not required for a cast-in-situ concrete wall body during the construction of the multi-storied and the small high-rise residential buildings with the shear wall systems, thereby improving the prefabrication rate of an assembled concrete structure, realizing the industrialized operation on a construction site, being used for building of industrialized residences and effectively overcoming the defects in the existing assembled concrete structure.
Description
Technical field
The invention belongs to building engineering field, relate to the building structure construction technology, relate in particular to and adopt assembling-cast-in-place job practices to realize being used for the close rod structure technology of shear wall system housing construction.Be applicable to the multilayer and the little high residential building of shear wall system, also can be used for the shear wall structure of other industry and civilian construction.
Background technology
With the propelling of China's housing industrialization and going deep into gradually of environmental protection construction, adopt prefabricated assembled construction technology to become one of construction means.Fabricated construction has advantages such as batch production production, site operation is simple, but show according to existing research and practice, existing fabricated construction or assembled-monolithic structure exist globality and shock resistance is relatively poor and cast-in-situ concrete is partly constructed the lower defective of industrialization degree, and this has limited the application of fabricated construction.Existing assembling shear wall structure system mainly contains the plank frame of prefabricated big plank frame, employing GFRG (glass fiber is strengthened the gypsum hollow plate) etc.Prefabricated large panel structure wall is the prefabricated assembled concrete structure, and the plank frame of GFRG is the non-bearing system, is mainly used in the retaining wall of low layer (1-2 layer).
Summary of the invention
The object of the present invention is to provide batch production degree height, speed of application fast, can realize housing industrialization, the close rod structure of the assembling-Cast-in-situs type that is used for the shear wall system housing construction that structural performance is good, safe and reliable.
The present invention forms by following structure design and construction, be provided with in the cavity of pre-cast building hollow wall mould behind the close post reinforcing bar that cast-in-situ concrete becomes close post and cast-in-place corner post, cast-in-place beam, floor and other members connect and compose the close rod structure of assembling-Cast-in-situs type, be used for the shear wall system housing construction.
Pre-cast building hollow wall mould adopts prefabricate modularization building hollow wall mould, and hollow interior wall mould of building and building hollow exterior wall mould are arranged, and the thickness of the cavity tabula of building hollow wall mould is 30～60mm.Pre-cast building hollow exterior wall mould can also be finished decoration of exterior wall and insulation in precast yard produces, make hollow exterior wall mould and decoration, heat insulation integrated.According to the needs of building function of use and structure stress, pre-cast building hollow wall mould can be made by prefabricated reinforced concrete, gypsum glass fiber, lightweight concrete material.To build the hollow wall mould installs at the construction field (site), and in the cavity of building hollow wall mould, lay cage of reinforcement and concreting, make close post and be combined into one with building hollow wall mould, after the reinforcing bar of the reinforcing bar of close post and cast-in-place corner post, cast-in-place beam and precast floor slab and other structural element is linked to be according to a conventional method, stablize firm close post overall structure through cast-in-place formation.
In multilayer or the construction of little high residential building, be the connection that realizes the close post cage of reinforcement of upper and lower floor in the building hollow wall mould cavity, be provided for the hole of close post reinforcing bar binding in the bottom of building hollow wall mould cavity.The cast-in-situ concrete after reinforcing bar binding connects of the close post cage of reinforcement of upper and lower floor links into an integrated entity the close post of upper and lower floor, and also making multilayer or little high residential building by close post is to stablize firm overall structure.
In practice of construction, when adopting precast floor slab or superposed type floor, floor directly is held on beam form or the cast-in-place beam, and on-site concrete is built only needs a small amount of post, beam forms; As when adopting cast-in-situ floor, then floor template should be set.
Realize that the said structure job practices comprises: pre-cast building hollow wall mould, cast-in-place close post, cast-in-place corner post and cast-in-place beam, the connection between prefabricated or cast-in-place floor and these members; The job site adopts lifting appliance to carry out the installation of pre-cast building hollow wall mould, builds reinforcing bar binding and concreting in the hollow wall mould cavity.The close rod structure of assembling-Cast-in-situs type adopts pre-cast building hollow wall mould, carry out the cast-in-situ concrete construction after on-the-spot the installation, form the close rod structure of good whole, on function of use, building structure and construction technology, all have significant superiority than traditional fabricated construction.
The present invention has following useful effect: in the multilayer and little high residential building of shear wall system, owing to adopt the good close rod structure of assembling-Cast-in-situs type of structural performance of the present invention, in construction, in-situ concrete wall need not traditional wall form; Improve the prefabricated rate of prefabricated concrete structure, realized the industrialization operation of job site; Can be used for the construction of industrialization dwelling house, effectively overcome the defective that present prefabricated concrete structure exists.
