Joint connecting format for concrete-filled square steel tubular column and concrete-filled rectangular steel tubular beam

Abstract

The invention discloses a joint connecting format for a concrete-filled square steel tubular column and a concrete-filled rectangular steel tubular beam. Soil columns and soil beams are involved, fixing clamping blocks are arranged on the two sides of the soil column, locking blocks are fixedly connected to the two sides of the fixing clamping blocks, locking rods are inserted between the two locking blocks, connecting blocks are fixedly connected to the outer walls of the two sides of the fixing clamping blocks, connecting grooves are formed in the sides, away from the fixing clamping blocks,of the connecting blocks, one ends of the soil beams are inserted into the connecting grooves, limiting rods are slidably inserted to the two ends of the connecting blocks, the two sides of the soilbeams are both provided with clamping grooves corresponding to the limiting rods, and the top ends of the limiting rods are fixedly connected with pulling blocks. By adopting the assembled design, thesoil beams and the soil columns can be connected more conveniently, rapidly and efficiently, on-site construction is convenient, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction-related products, in particular to a joint connection form of a square steel tube concrete column-rectangular steel tube concrete beam. Background technique [0002] Concrete filled steel pipe is to pour concrete into the steel pipe and compact it to increase the strength and rigidity of the steel pipe. Generally, we call the concrete-filled steel tube concrete with a concrete strength level below C50 called ordinary steel-filled steel tube concrete; the concrete-filled steel tube with a concrete strength level above C50 called high-strength steel tube concrete; , because the steel tube concrete structure has the advantages of both reinforced concrete structure and steel structure, and its mechanical performance is superior, so it is widely used in construction projects. [0003] However, in the engineering practice of frame structures, the existing concrete-filled steel tube columns are mostly combin...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of square concrete-filled steel tube column-rectangular concrete-filled steel tube beam node connection form, to solve the above-mentioned background technology, the existing concrete-filled steel tube columns are mostly connected with reinforced concrete beams or steel beams in the engineering practice of frame structures The form of combined connection, which is all composed of steel pipe concrete members, is rarely used in practice, and the existing joint connection form is complex in structure, requiring a lot of on-site welding work, which is time-consuming and labor-intensive.
