One-time prefabrication technology construction technology of prefabricated laminated slab water-stop anti-beam

Abstract

The invention discloses a prefabricated superposition board water-stopping upstanding beam once prefabrication technology construction process. The construction process includes an aluminum alloy template, a water-stopping beam reinforcing bars, a back concrete plate, and prefabricated concrete member; the prefabricated concrete member is arranged on the bottom of the back concrete plate; the aluminum alloy template and the water-stopping beam reinforcing bar are arranged on the center of the back concrete plate; and the aluminum alloy template is arranged on an outer side of the water-stopping beam reinforcing bar. The problem that the construction quality cannot be ensured in the conventional structures can be solved; in the conventional construction methods, cleaning of a contact surface between first pouring and second pouring needs to be ensured, roughening is performed, vibrating of concrete must be compact, but actually the cognitive level and the construction operation level of construction workers are difficult to control, and then the prefabricated superposition board water-stopping upstanding beam once prefabrication technology construction process is very important; and the construction method is improved, and materials are optimized, and then construction operation is simple, the construction quality can be ensured, and leakage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a prefabricated laminated slab waterproof anti-beam primary prefabrication technology construction process. Background technique [0002] The prefabricated concrete structure construction technology has been used on a large scale in the process of housing industrialization in my country. Among them, the laminated slab in the prefabricated concrete structure is composed of prefabricated slabs and cast-in-place reinforced concrete layers, and the lower layer is prefabricated with steel bars. Composite slab, the upper layer is a post-cast cast-in-place concrete structure, and the two layers are jointly stressed. During the construction of some inverted beams in the construction of prefabricated concrete structures, the secondary pouring construction has the problem of combining new and old concrete, which leads to the inability to play the role of the water-stop beam...

Problems solved by technology

[0003] The purpose of this invention is to propose a prefabricated laminated slab water-stop anti-beam primary prefabrication technology construction process, aiming at solving the requirement that the construction quality cannot be guaranteed in the traditional structure. In the traditional construction method, the contact surface between the primary pouring and the secondary pouring must be clean and smooth Chiseling, and vibrating for compaction, but in fact it is difficult to control the cognitive level and construction operation level of construction personnel. Therefore, it is particularly important to propose a prefabricated construction method for prefabricated laminated slab water-stop and reverse beams at this stage. Through construction The improvement of the method and the optimization of the material can make the construction operation easier and ensure the quality of the construction, so as to avoid the occurrence of leakage
