Steel structure wall and modular steel-concrete composite building structure

Abstract

The invention provides a steel structure wall and a modular steel-concrete composite building structure. The steel structure wall comprises two opposite wall steel plates, lattice columns and lattice beams, wherein the lattice columns and the lattice beams are arranged between the two wall steel plates; a first cavity is formed between the two wall steel plates, the two wall steel plates are connected to the lattice columns and / or the lattice beams respectively, and the two wall steel plates are connected through split bolts; and two lattice columns and two lattice beams are respectively arranged, a rectangular frame is defined by the two lattice columns and the two lattice beams, the two lattice columns are opposite, and the two lattice beams are opposite. The modular steel-concrete composite building structure comprises a plurality of room modules, wherein the plurality of room modules are in butt joint, each room module comprises a plurality of wall bodies and a floor slab which are connected to the upper ends of the wall bodies, at least one wall body in the plurality of wall bodies is an outer wall, and the outer wall is the steel structure wall body.

Description

technical field [0001] The present disclosure relates to the field of steel structure buildings, in particular to a steel structure wall and a modular steel-concrete composite structure building structure. Background technique [0002] At present, steel structure residences are mainly low-rise buildings such as villas and new rural houses, accounting for less than 2% of the overall housing market. The main reasons are as follows: 1. Steel structures have poor fire resistance and corrosion resistance. The cost of anti-corrosion performance is too high, resulting in the cost of steel structure residences being much higher than that of reinforced concrete buildings; 2. Since steel structure residences are mostly steel frame structures, steel structures have higher requirements for house types, and leaking beams and columns are serious; 3. Due to The sound insulation performance of steel is poor, so steel structure houses generally have sound insulation problems, which affect th...

[0002] At present, steel structure residences are mainly low-rise buildings such as villas and new rural houses, accounting for less than 2% of the overall housing market. The main reasons are as follows: 1. Steel structures have poor fire resistance and corrosion resistance. The cost of anti-corrosion performance is too high, resulting in the cost of steel structure residences being much higher than that of reinforced concrete buildings; 2. Since steel structure residences are mostly steel frame structures, steel structures have higher requirements for house types, and leaking beams and columns are serious; 3. Due to The sound insulation performance of steel is poor, so steel structure houses generally have sound insulation problems, which affect the experience of residents; 4. The tensile capacity of steel is much stronger than the compressive capacity, so steel structures are not suitable for super high-rise buildings, and steel bars can be used for public buildings Concrete core tubes, and for residential buildings it will result in larger pools

2-3 floors can be hoisted at one time, and the construction speed is relatively fast; however, the lattice steel tube beam concrete composite structure still has the following problems: 1. Sound insulation; Safety; 3. The amount of use just now is high, and the cost is high; 4. Only vertical construction is solved, and the construction of the floor is complicated, and it takes too long compared to the wall, which seriously affects the overall construction efficiency
