Abstract

The invention provides a construction method for prefabricated superposed beams and slabs. The construction method comprises the steps of measuring and laying out, and performing horizontal control laying-out and elevation control laying-out; manufacturing a temporary steel pipe support, and rapidly erecting the temporary support by using a laser gradienter before superposed slabs and superposed beams are hoisted; hoisting the superposed beams and the superposed slabs in place, and adjusting and fixing the superposed beams and the superposed slabs; cleaning the surfaces of the superposed beams and the superposed slabs, and treating splicing seams and joints of the superposed slabs by using gridding cloth and expansive concrete; and after pipeline laying and rib arrangement are completed, erecting a limiting formwork, and pouring concrete. According to the construction method, the problem of cracking of the splicing seams of the superposed slabs is solved, a method for quickly adjusting the temporary support at the bottom of the superposed beams and the superposed slabs is provided, the construction efficiency is improved, the quality is easily guaranteed, the economic benefit and the social benefit are obvious, and the problems in the aspects of temporary support, lateral formworks, splicing seam cracking, finished product protection and the like are solved.

Description

technical field [0001] The invention relates to the technical field of construction of prefabricated buildings, in particular to a construction method for prefabricated composite beams and slabs. Background technique [0002] Prefabricated structure is the abbreviation of prefabricated concrete structure, which is a concrete structure that is assembled or connected with prefabricated components as the main force-bearing components. [0003] Prefabricated reinforced concrete structure is one of the important directions for the development of my country's building structure. It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring the quality of construction projects. Compared with the construction method, the prefabricated PC structure is conducive to green construction, because the prefabricated constructi...
