Prefabricated formwork-free floor slab and construction method

Abstract

The invention discloses a prefabricated formwork-free floor slab and a construction method. The prefabricated formwork-free floor slab comprises a bed board, an edge strip is arranged on one side of the bed board, an inserting groove is formed in the other side of the bed board, the edge strip is inserted into the inserting groove, connecting ribs are evenly arranged in the bed board in advance, a plurality of rows of fixing frames are arranged on the bed board in the front-back direction, rib frames are arranged on the fixing frames, an embedded stud is pre-arranged in the bed board, the bottom of the embedded stud is connected with a connecting plate, the connecting plate is located in the bed board, and a penetrating hole is formed in the bottom of the fixing frame. The prefabricated formwork-free floor slab is a novel assembly type formwork composed of the bed boards, the connecting ribs, the rib frames, supporting ribs and the like, compared with a concrete laminated slab, the prefabricated formwork-free floor slab has the remarkable advantages that the self weight of components is light, and the construction cost is relatively low. Compared with a common wood formwork, construction is convenient and fast, the number of field bundled steel bars is reduced, steel bars are integrated with concrete after concrete pouring, dismantling is not needed, the construction period is short, and therefore efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated formwork-free floor slab and a construction method. Background technique [0002] In the production process of common concrete slabs, it is usually necessary to erect a support frame and install a formwork on the support frame. After the formwork is installed, it is necessary to make floor gluten on the formwork slab and bind the floor gluten to the steel cage. After completion, pour concrete , After the concrete is solidified, the formwork needs to be removed, and during the entire concrete floor production process, the workers have a lot of work to tie up the steel bars on the spot, the formwork installation and removal process takes a long time, and the production labor cost is relatively high. Contents of the invention [0003] The object of the present invention is to provide a prefabricated formwork-free floor slab and a construct...
