Non-dismantling bottom die floor plate for different-surface construction and construction method

Abstract

The invention discloses a dismounting-free bottom die floor plate for different-surface construction and a construction method, the dismounting-free bottom die floor plate comprises a bottom die, a bearing part and a hoisting assembly, the hoisting assembly is mounted on the top surface of the bottom die and used for conveying the bottom die to a preset position, and the bearing part is detachably mounted on the bottom surface of the bottom die to support the bottom die; the cast-in-place covering layer and / or the prefabricated covering plate integrally cover the top surface of the bottom die; the problem of temporary supporting of the floor plate can be solved, the plate thickness is not limited by the height of the steel bar truss any more, the construction cost is reduced, economical efficiency is better, and the requirements for material saving and carbon reduction are met.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a floor slab free from dismantling bottom formwork for different-surface construction and a construction method. Background technique [0002] With the development of prefabricated buildings, more and more types of floor slabs have appeared; the main floor slabs at this stage include wood formwork for cast-in-place concrete slabs, profiled steel plates, reinforced truss floor slabs and other bottom form reinforced truss floor slabs Wait. [0003] When the traditional cast-in-place concrete floor uses wooden formwork, there are many formwork supporting procedures, small support spacing, long construction period and high engineering cost; the profiled steel plate composite floor saves the formwork supporting process, improves the construction speed, and the bottom of the open section is not flat. The closed section is less economical and cannot be lapped; the steel truss fl...

Problems solved by technology

[0005] In view of this, the purpose of the present invention is to overcome the defects in the prior art, to provide floor slabs and construction methods without dismantling bottom formwork for construction on different surfaces, which can solve the problem of temporary support of floor slabs, and the thickness of the slabs is no longer affected by the height of the steel truss The constraints of the project reduce the cost of the project, the economy is better, and it meets the requirements of material saving and carbon reduction; the floor slab is processed in the factory the same as the existing steel truss floor slab; The lower gasket and connector II are fixed under the bottom formwork, hoisted in place and supported at the preset position, and pour concrete on the top surface of the bottom formwork. After the concrete pouring and curing are completed, remove the supports and steel trusses for recycling; The floor slab structure involved in this patent not only has the functions of no support and no need to remove the bottom form, but also solves the problem that the thickness of the slab is restricted by the height of the steel truss. It is more economical and meets the requirements of material saving and carbon reduction.
