Construction method of interlayer connection joints of combined prefabricated concrete walls

Abstract

The invention discloses a construction method of interlayer connection joints of combined prefabricated concrete walls. The construction method comprises the steps that the two combined walls and laminated slab prefabricated bottom plates on the two sides are assembled in a matched mode and poured to form the interlayer connection joints, each combined wall comprises a shear wall, a light filling wall and a laminated beam prefabricated bottom beam which are integrally prefabricated, and the bottom of each shear wall is provided with a retraction part and matched with the corresponding light filling wall to form a step structure; during construction, the tops of the laminated beam prefabricated bottom beams corresponding to the light filling walls are poured and serve as first supporting connection parts, then the upper-layer combined wall is hoisted to the position overlapped with the upper portion of the lower-layer combined wall, the bottoms of the light filling walls of the upper-layer combined wall are placed on the first supporting connection parts, then stabilizing is conducted through oblique supporting, and pouring is conducted through second post-poured concrete after the perpendicularity is adjusted; and finally, the light filling walls and the first supporting connection parts are subjected to joint filling, and construction is completed. According to the construction method, the construction sequence is reasonable, the process is convenient, fast and efficient, and the joint 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
