A construction method for interlayer connection nodes of combined prefabricated concrete walls

Abstract

The invention discloses a construction method for interlayer connection nodes of a combined prefabricated concrete wall, which comprises two combined walls and prefabricated bottom plates of laminated plates on both sides which are assembled and poured together, and the combined wall includes an integrated prefabricated shear The prefabricated bottom beam of force wall, lightweight infill wall and composite beam, the bottom of the shear wall is provided with an indentation and cooperates with the light infill wall to form a stepped structure; during construction, the composite beam corresponding to the light infill wall is prefabricated first The top is poured and used as the first supporting connection, and then the upper combined wall is hoisted to a position above and overlapping with the lower combined wall, and the bottom of the lightweight infill wall of the upper combined wall is placed on the first supporting connection Then use oblique supports for stabilization, adjust the verticality and use the second post-cast concrete for pouring; finally fill the joint between the lightweight filling wall and the first support to complete the construction. The construction sequence of the invention is reasonable, the process is convenient and efficient, and the node connection quality is easy to control.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a construction method for interlayer connection nodes of combined prefabricated concrete walls. Background technique [0002] Prefabricated buildings refer to the production of some or all of the components and parts of the building in the prefabricated factory, and then transported to the construction site, using reliable connection methods and installation machinery to assemble the components to form a building with design and use functions. Compared with the construction of cast-in-place structures, prefabricated structures have the advantages of convenient construction, fast project progress, little impact on the surrounding environment, and easy guarantee of the quality of building components. The prefabricated concrete structure is of positive significance to promote the process of urban construction, improve project quality, promote energy conservation and emission r...

Problems solved by technology

However, this type of connection brings inconvenience to the hoisting and temporary fixing of the prefabricated shear wall. During installation, the prefabricated shear wall must be erected in mid-air to bind the steel bars in the cast-in-place connection area and the cast-in-place connection area. concrete

Ordinary oblique supports cannot complete the erection task, and a special modification design is required for the supports, which increases the construction cost and affects the construction efficiency. Even so, it is difficult to guarantee the verticality of the prefabricated wall installation, which will eventually affect the construction quality
