Construction technology of basement cast-in-situ hollow floor slab steel mesh box

Abstract

The invention relates to a construction technology of a basement cast-in-situ hollow floor slab steel mesh box. The construction technology comprises the following steps that the placement position lines of reinforcing steel bars and box formworks are determined; floor slab floor iron and box formwork side rib beams are bound, specifically, the floor slab floor iron and the box formwork side rib beams are bound sequentially according to the positions of the placement position lines; an embedded pipeline is laid; cushion blocks are arranged on the lower portion of steel mesh box formworks to bemounted and used for guaranteeing the thickness of concrete on the lower portions of the box formworks; the steel mesh box formworks are mounted; after the steel mesh box formworks are placed, floorslab upper iron is bound; a construction facilitating channel is built, and a concrete conveying tube is erected, so that constructors can operate and walk through conveniently, and the box formworksand floor slab reinforcement steel bar finish products are protected; concealed check acceptance is conducted; concrete pouring is conducted; maintenance is conducted; the formworks are disassembled;and a post-pouring area is arranged. According to the construction technology, the cost is saved, the usage amount of concrete is saved through the method, the self weight of the structure is lowered,the engineering cost is lowered, the effect of earthquake is reduced, the using function is improved, and the practical space is expanded.

Description

technical field [0001] The invention belongs to the technical field of hollow floor construction, and in particular relates to a construction process for a cast-in-place hollow floor steel mesh box in a basement. Background technique [0002] In the process of building structure construction, floor construction is an indispensable and important link. At present, ordinary primary and secondary beam floors are still the most widely used floor in building structures. The disadvantages of this kind of floor during construction are: the entire structure is not beautiful due to the influence of beams; the construction formwork progress is slow, the formwork loss is large, resulting in an increase in construction costs; the sound insulation is poor, the noise is large; it is not conducive to equipment installation, etc. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a basement cast-in-place hollow floor steel mesh box...
