Description

A temporary support structure for a floor deck

technical field

The invention relates to the field of building construction support, in particular to a temporary support structure for a floor deck.

Background technique

In recent years, with the deepening of the application of steel structures in the construction field and the increase of awareness of environmental protection, detachable self-supporting floor decks are generally laid between the existing steel structure beams. The reusable formwork is realized through the detachable combination of the steel grid frame and the formwork. At the same time, the welded connection between the end of the steel truss and the steel structure beam enables the detachable self-supporting floor deck to achieve a certain span without support, reducing the use of scaffolding during horizontal structure construction. However, when the span is large or the pouring of the floor slab is thick, the middle part of the floor slab needs to be supported. Some floor slabs also need to be supported and arched according to the design requirements or when the span exceeds 4 meters. However, it is cumbersome to support the floor slab by scaffolding, and the floor slab poured on the lower floor needs to be maintained until it has a certain strength before it can be built, which seriously affects the construction efficiency. Chinese patent publication CN104674992A is a method and structure for supporting a suspended reinforced truss floor deck, which discloses that the suspender is pulled by a suspending component that is buckled on the lower wing of the upper H-shaped steel beam, and the suspender is connected to The supports support the reinforced truss floor deck. Although the hanging support method can replace scaffolding and be used flexibly, there are some problems in the supporting structure of the hanging steel truss floor deck: the suspension rods are poured in the concrete to cause consumption and waste resources; the hanging supporting structure is extremely inconvenient to install and disassemble , and the structure is unstable and easy to shake. Chinese patent CN205531315U discloses a detachable reinforced truss floor deck system, in which the floor deck connected to the upper flange of the steel beam is supported by the truss supports at both ends supported on the lower flange of the steel beam. The truss support can solve the problems of some suspended support structures, but there are the following problems during use:

1. The adaptability of the truss support is poor, the same truss support cannot meet the support of floor decks with different spans, and when the span of the floor deck is large, the truss supports cannot even bear their own weight and fail due to deformation;

2. The truss support cannot adjust the amount of arching of the floor deck at will, which is inconvenient to use;

3. The self-heavyness of the truss support is not convenient for on-site installation and construction.

Contents of the invention

The content of the present invention is to provide a temporary support structure for floor slabs, which can quickly support the floor slabs between steel structures, arbitrarily adjust the amount of arching of the floor slabs, and is not affected by the lower floor slabs and is easy to install.
