Upside-down type supporting system of floor support plate

Abstract

The invention relates to the field of supporting of residential floor pouring, in particular to an upside-down type supporting system of a floor support plate. The system comprises multiple truss girders and multiple wood keels used for supporting the floor support plate, two ends of the truss girders are provided with clamping opening upside-down parts used for being mounted on a lower flange, clamping opening parts of the clamping opening upside-down parts are provided with ejecting bolts used for ejecting the lower flange from bottom to top, multiple fastening pin holes are formed in two ends of the truss girders, fastening pins used for preventing lateral moving of the clamping opening upside-down parts are mounted in fastening pin holes, multiple vertical embedded pipes are mounted onthe truss girders, and are provided with inner threads, first U-shaped mounting brackets upwards extending out of the embedded pipes and heights capable of being adjusted in a thread manner are mounted in the embedded pipes, and are used for supporting the wood keels, mounting is rapid and convenient, the self weight is small, two persons can finish mounting, multi-layer simultaneous constructionis carries out, a large amount of cost can be saved, a plate bottom is flat and attractive, and the whole assembling efficiency can be improved.

Description

technical field [0001] The invention relates to the field of support for pouring residential floor slabs, in particular to an upside-down support system for floor slabs. Background technique [0002] At present, the floor structure of high-rise residential buildings with steel structure mostly adopts a steel structure-concrete hybrid structure. After the concrete has been cured for a period of time, the support system is removed, and the pouring of the floor slab is completed. [0003] In the prior art, there are mainly two types of pouring support systems for high-rise cast-in-place concrete slabs: 1. Full house floor support; 2. Reinforced truss formwork or profiled steel plate floor support. [0004] Among them, the full house floor stand needs to be erected on the ground or the next floor. This erection method requires a large investment in turnover materials, a long construction period and high investment costs. Because it occupies the construction space of the next fl...

[0004] Among them, the full house floor support needs to be erected on the ground or the next floor. This erection method requires a large investment in turnover materials, a long construction period and high investment costs. Because it occupies the construction space of the next floor, the construction of the lower floor requires Wait for the scaffolding to be dismantled before starting. The pouring of each floor restricts the construction of the lower floor

As for the profiled steel plate floor slab, it is first necessary to use crane equipment to assist hoisting, which limits the use of hoisting equipment, takes up the vertical transportation time of the crane, and costs a lot of mechanical shifts; secondly, the profiled steel plate floor deck has a large steel content and high cost; During the construction of pipeline laying, the vertical and slab rib laying must be placed on the upper part of the slab rib, and the upper reinforcement construction space will be affected for the floor slab with a small thickness

Although the price of the veneer is low, due to its cumbersome construction and the large amount of labor required, the overall cost is relatively high and the economic efficiency is low.

The ribs of the profiled steel plate floor deck are relatively high, and the thickness of the floor structure layer is large, which reduces the net height of the building. Stressed steel bars need to be manually welded on site with short steel bars, and the efficiency is slow
