Bidirectional laminated slab concrete structure and integral type joint seam construction method

Abstract

The invention belongs to the technical field of concrete structures and particularly relates to a bidirectional laminated slab concrete structure and an integral type joint seam construction method.The bidirectional laminated slab concrete structure processed through the construction method comprises a first laminated slab prefabricated layer, a second laminated slab prefabricated layer, a laminated slab cast-in-situ layer and a flexible anti-crack structure. the bidirectional laminated slab concrete structure has the following advantages: 1, a support frame body of a bottom die plate at ajoint seam does not need to be set up during the construction process to improve the construction efficiency; 2, the construction space is saved, the worker passing space and the material transportation space are increased during the construction process, and the construction efficiency is indirectly improved; 3, a larger role is played in the hogging moment born by a resisting floorslab mainly;4, the proper amount of the integral type support frame body at the joint seam can be considered to meet the bearing capacity of the largest bending moment of the floorslab; and 5, the flexible anti-crack structure is adopted for filling treatment at the junction of the laminated slab prefabricated layers and the laminated slab cast-in-situ layer, so that the risk that the junction surface of newand used concrete generates a crack is reduced to improve the project quality.

Description

technical field [0001] The invention belongs to the technical field of concrete structures, and in particular relates to a two-way laminated slab concrete structure and an integral joint construction method thereof. Background technique [0002] With the steady and rapid development of my country's social economy in recent years, the demographic dividend has gradually disappeared and the problem of high energy consumption in the construction industry has become increasingly prominent. The government's requirements for energy conservation, emission reduction, and environmental protection are increasing. The traditional concrete structure production method is mostly on-site pouring, which has high work intensity, labor-intensive, poor working conditions, long construction period, serious energy waste, serious material loss, and a lot of construction waste, resulting in poor project quality and heavy environmental pollution. The design is seriously inconsistent. Most of the co...
