A composite concealed beam of pre-embedded steel

Abstract

The invention discloses a combination hidden beam of pre-buried profile steel. The combination hidden beam of the pre-buried profile steel comprises steel beams, concrete slabs, horizontal steel bars, longitudinal steel bars and U-shaped-structure steel bars. The steel beams are pre-buried into the concrete slabs, and the U-shaped-structure steel bars are arranged between the concrete slabs and webs of the steel beams. In the concrete slabs, the horizontal steel bars are welded to the bottom faces of the top flanges of the steel beams and the top faces of the bottom flanges of the steel beams, the width of the upper flanges of the steel beams and the width of the lower flanges of the steel beams can be unequal and can also be equal, and the height of the steel beams and the thickness of the concrete slabs are equal. According to the combination hidden beam of the pre-buried profile steel, all combination materials play roles of themselves and work cooperatively, the strength and rigidity of a traditional hidden beam are greatly improved, meanwhile, the interior net storey height is effectively increased, flatness of a concrete bottom plate is ensured, space separation and decoration are facilitated, and flexibility of space separation is effectively improved. The combination hidden beam of the pre-buried profile steel has the advantages of being simple in structure, convenient to construct, good in overall stress performance, capable of saving materials and the like and can be widely applied to civil buildings and high-rise buildings.

Description

technical field [0001] The invention relates to the technical field of new structures of civil engineering, in particular to a composite concealed beam of pre-embedded section steel. Background technique [0002] With the rapid development of my country's economy, the process of urbanization is accelerating day by day, and houses and houses have sprung up in cities like mushrooms after rain. In the design of civil buildings, it is often encountered that a partition wall is arranged on the floor to separate a large space. Since the partition wall cannot be placed directly on the floor, the designer often installs a secondary beam under the partition wall during structural design, which can Avoid damage to the floor under the partition wall, but the secondary beams will inevitably be arranged in the living room, bedroom, etc., and exposed at the bottom of the slab. If these problems are not dealt with properly, the use function of the house may be greatly reduced, such as: th...

AI Technical Summary

Problems solved by technology

Since the concealed beam is a stressed member completely hidden in the slab member or concrete wall member, the design method is to place sufficient stressed longitudinal reinforcement at the concealed beam to bear the load transmitted from the partition wall and the floor. The existence of the secondary beam can solve some problems caused by the secondary beam, such as: flat floor, clear height of the house, beautiful house, flexibility of partition space, etc.; however, due to the limited bearing capacity and stiffness of the existing concealed beam, it often cannot meet the design requirements
