Assembled shear wall post-pouring ring beam template and plate support integrated design and construction method

Abstract

The invention belongs to the field of assembled building construction, and particularly relates to an assembled shear wall post-pouring ring beam template and plate support integrated design and construction method. The assembled shear wall post-pouring ring beam template and plate support integrated design and construction method comprises the first step of template system calculation model determining, the second step of template system bearing capacity checking calculation, the third step of prefabricated plate support system calculation model determining, the fourth step of prefabricated plate support system bearing capacity checking calculation, the fifth step of template system component material determining, the sixth step of back ridge manufacturing, the seventh step of template manufacturing, the eighth step of right-angle bolt manufacturing, the ninth step of template inner support manufacturing, the tenth step of template installing, the eleventh step of prefabricated platehoisting and the twelfth step of concrete pouring. The assembled shear wall post-pouring ring beam template and plate support integrated design and construction method solves the key technical problems about difficult post-pouring ring beam template fixing, plate bottom slurry leakage, displacement and the like, template and prefabricated plate support integration is achieved, prefabricated platebraces are saved, post-pouring ring beams meet the bare concrete requirement, the template standardization degree is high, factory production and assembled installation are achieved, cyclic usage is repeated, and the national environment protection and energy saving requirements are met.

Description

Technical field [0001] The invention provides an integrated design and construction method of a post-casting ring beam template and a slab support of an assembled shear wall, which belongs to the technical field of concrete prefabricated construction, and is suitable for the post-cast ring beams of the inner and outer walls of the assembled shear wall structure Integrated design and construction of formwork and prefabricated board support. Background technique [0002] In recent years, as the promotion of prefabricated buildings in my country continues to increase, prefabricated buildings have developed rapidly. In order to make the connection of the horizontal member nodes meet the seismic requirements, it is necessary to cast the ring beam after the design of the precast shear wall top. However, there is still a lack of scientific design and construction methods for the post-cast ring beam formwork. Usually, the vertical middle part of the post-cast ring beam formwork is set t...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide an integrated design and construction method of post-cast ring beam formwork and slab support for prefabricated shear walls. Save the temporary support of the prefabricated slab; after calculating the bearing capacity of the formwork under the horizontal and vertical construction loads, the stress members of the formwork system are determined, which not only solves the problem that the post-cast ring beam formwork cannot bear the floor construction load and formwork slippage and expansion Key technical problems such as exposed ribs, etc., and make the post-cast ring beam achieve the effect of fair-faced concrete, which greatly saves the comprehensive cost of grinding and leveling the post-cast ring beam in traditional technology; through fine-tuning screw adjustment, the formwork and precast slabs can be tightly fitted without leakage of grout. The accuracy of the bottom level of the prefabricated slab is controlled in the range of ±0.5mm~±1.0mm, which meets the flatness requirements of fair-faced concrete and saves a lot of leveling putty on the bottom of the slab. , stable and reliable quality, in line with energy saving and green construction requirements, has broad application prospects and significant social and economic benefits
