Embodiment Construction
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0021] The integrated floor member construction method includes the following steps:
[0022] A), carry out the process design of the integrated floor slab member according to the structural construction drawings, determine the geometric dimensions of the shaped steel bars 100 and the factory production lofting drawings, and carry out factory production, such as figure 1 shown.
[0023] B) In the same way, determine the lofting drawings for the formwork production of the integrated floor slab components, and carry out the processing and production of the formwork. The spacing of trusses, the size of single trusses and the selection of templates are adjusted according to the thickness of the structural floor and the form of the span. Such as...

The invention discloses an integrated floor component construction method. The integrated floor component construction method includes: A) finishing prefabrication of shaping rebars and a formwork in a factory according to design requirements; B) transporting the shaping rebars and the formwork to a construction site and assembling the rebars and the formwork to obtain an assembled component; C) hoisting the assembled component in position, correcting and finally fixing to enable the rebars at two ends of the assembled component to be displaced on two structural edge beams; D) integrally pouring concrete and maintaining to obtain an integrated floor component; E) removing the formwork when the maintained concrete reaches to the designed strength. By fabricating the shaping rebars in the factory, positioning and binding quality of the rebars is guaranteed; by assembling on the construction site, heavy-cargo transportation can be avoided, and a production field of the prefabricating factory can be reduced; by pouring the concrete during construction, the integrated floor component can be formed, and the problem of poor anti-seismic property of connection joints of prefabricated reinforced concrete is avoided.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method of reinforced concrete floor components. Background technique [0002] In the process of exploring the technical process of housing industrialization, the standardization of components and industrial production have been explored for nearly 70 years, but how to solve the problem of connecting nodes of these prefabricated reinforced concrete components has not been formed to be compatible with cast-in-place. The seismic performance of reinforced concrete structural nodes is comparable to the complete technology, thus restricting the development of the overall technology. [0003] After the Tangshan earthquake in the 1970s, the prefabricated component industry in the construction field was greatly impacted. In big cities like Shanghai, a large amount of prefabricated factory land was developed into construction land, and the building structure returned ...
