Floor plate connected by zigzagging plates and preparation method thereof

Abstract

The invention discloses a floor plate connected by zigzagging plates and a preparation method thereof. The floor plate comprises a base plate (1) and the zigzagging plates (3) are above the base plate(1) and a steel layer (2) is under the zigzagging plates (3). The preparation method comprises the following steps: step 1, cutting and bending steel plates to form the zigzagging plates; step 2, strapping to obtain the steel layer and welding the steel layer in a corresponding position of the zigzagging plates to form a frame; and step 3, fixing the frame on the base plate to obtain the floor plate. The invention has the advantages of convenient manufacture, high welding quality, low engineering cost and wide application range.

Description

technical field [0001] The invention relates to a floor deck, in particular to a floor deck connected by a folded plate and a preparation method thereof. Background technique [0002] With the rapid development of multi-high-rise steel structures, higher requirements have been placed on the construction period of the project. The industrial production of steel structure components has greatly shortened the construction period of the project. The construction method of the floor slab has become an important factor affecting the construction period. Reinforced truss floor deck belongs to the third generation of steel structure supporting floor deck, which is quite different from ordinary non-combined profiled steel plates and combined profiled steel plates. It is a steel floor deck product that is formed into a reinforced truss, and then is resistance spot welded with the profiled steel plate. However, the floor deck of the reinforced truss structure has the following disadva...

AI Technical Summary

Problems solved by technology

However, the floor deck of the steel truss structure has the following disadvantages: 1. The unsupported length of the steel truss floor deck is very small. When the thickness of the slab is 130mm, the allowable span of the simply supported slab in the construction stage is only 3.3 meters, and the top of the truss steel bar is a single steel bar, so no additional reinforcement flange can be provided, and its application range is small, and it is more restricted in practical application 2. The steel consumption of truss bars is large, and the project cost is high, which is not conducive to the promotion of construction industrialization; 3. The production of truss bars is complicated, and the web bars need to be bent in advance before being welded with the chord bars, and special equipment is required Processing and production; 4. The welding quality between the truss reinforcement and the bottom plate is poor. The web plane of the truss reinforcement is a curve, the section is circular, and the thickness of the bottom plate is very thin, which is very easy to weld through, which affects the appearance of the bottom of the plate

Therefore, the existing technology has the problems of troublesome manufacture, poor welding quality, high engineering cost and limited application range.
