Concrete formwork support device for floor pouring

Abstract

The invention provides a concrete formwork supporting device for floor slab concreting. The device comprises main steel-structure beams and a formwork and is characterized in that height adjustable key keels are arranged between the two opposite main steel-structure beams at intervals, auxiliary keels are arranged on the key keels at intervals, and the formwork is placed on the auxiliary keels; a vertical bolt is made to move upwards or downwards by rotating a nut, so that rising or descending of a horizontal beam is realized, the whole key keels are finally made to be stably fixed between the two steel-structure beams by replacing upper cushion blocks and / or lower cushion blocks in different heights or thicknesses, floor slab or floor clapboard concreting requirements are met, and embedding of embedded parts such as cable tubes or cable boxes is facilitated during concreting. According to the device, cross construction such as wall construction can be conducted, working efficiency is improved effectively while construction quality is guaranteed, construction progress is accelerated, and form removal and frame unloading are extremely convenient and fast. The device has the advantages of being capable of making construction convenient and fast, safe and reliable in cross construction, short in construction duration, convenient to dismount, capable of being used repeatedly, low in cost and the like.

Description

technical field [0001] The invention relates to a support device, in particular to a concrete formwork support device for floor pouring, and belongs to the technical field of design and manufacture of building formwork support devices. Background technique [0002] When constructing a frame structure building, concrete floors are poured. In the prior art, when pouring concrete floor slabs, either full scaffolding is used, or profiled steel plates are used to support the template. When using full scaffolding for support, not only the construction process is complicated, the work efficiency is low, the labor intensity is high, time-consuming and labor-intensive, but also it is necessary to wait for the poured concrete to solidify and the maintenance is completed before the formwork and frame can be removed, so that cross-construction cannot be carried out , Seriously affecting the construction progress and deadline. When the profiled steel plate is used for support, there wi...
