a steel structure beam

Abstract

The invention discloses a steel structure beam, which comprises a steel beam. The steel beam includes an upper plate. Several first through grooves are evenly arranged on the upper plate. A channel steel is connected in the first through groove, and the channel steel is close to the upper plate. The end is provided with a second through groove, the second through groove is nested and connected to the rafter, the top of the rafter is inserted into the second through groove on the upper part of the channel steel installed on the adjacent steel beam, and the second through groove on the upper end of the channel steel is nested and connected to the adjacent For the corresponding rafters on the steel beam, there are several first reinforcement holes on both sides of the channel steel, and steel bar sleeves are installed in the first reinforcement holes, and limit holes are set on both sides of the channel steel away from the end of the bottom support plate, and the limit holes are close to the support plate One side is provided with a first threaded hole, the first threaded hole is connected with a first fixing bolt, and the first fixing bolt is connected with the L-shaped block through the fixing hole. The invention can solve the deficiencies of the prior art and improve the overall stability and anti-seismic performance of the steel structure building.

Description

technical field [0001] The invention relates to the technical field of steel structure buildings, in particular to a steel structure beam. Background technique [0002] In recent years, steel structure buildings have obvious advantages in terms of energy saving, high efficiency, environmental protection and industrialization compared with brick-concrete structures. With the development of industry, steel structure components are also developing towards large-scale development. , earthquake resistance, good thermal insulation performance, dry construction, short construction period, low cost and other advantages, light steel building structures have developed rapidly in Europe and the United States, in the United States, Canada, Australia, Japan, Sweden and other countries, the steel structure in Steel consumption has accounted for more than 30% of steel production, steel structure buildings account for more than 40% of the total residential building area, and single-story an...

Problems solved by technology

[0004] In steel structure houses, the beam structure is essential and must have sufficient bearing capacity. In terms of strength and integrity, the stability of the house structure must also be ensured. In terms of earthquake resistance, corresponding technical and structural measures should also be adopted. Domestic Invention patent CN 206971544U discloses a combined H-shaped structural steel, which can provide a combined H-shaped structural steel with adjustable use width, high structural strength and strong practicability, but it only guarantees its own structure. The overall stability is indeed insufficient, and there is a lack of steel beams with stable and earthquake-resistant structures for overall steel structure buildings in the market
