Joint structure for connecting accessory structure and stiff concrete beam and construction method

Abstract

The invention provides a joint structure for connecting an accessory structure with a stiff concrete beam and a construction method, and belongs to the technical field of building construction. The invention aims at providing a stiff steel structure joint so as to effectively combine an embedded part of the accessory structure with the stiff concrete beam. The joint structure comprises a stiff concrete structure, an accessory structure embedded part, a section steel rib and a connecting piece, wherein the section steel rib is arranged in the stiff concrete structure in an embedded mode, a section steel rib stiffening rib is arranged on the section steel rib, the top end of the section steel rib is connected to the accessory structure embedded part through the connecting piece, and the accessory structure embedded part is anchored on the stiff concrete structure through an embedded part anchor bar. The novel joint structure solves the problems of insufficient embedding space and unreliable force transmission of embedded parts of accessory structures such as a curtain wall and a steel connecting bridge, and avoids unsafe factors of damage of a post-embedded steel bar method to a main body steel reinforced concrete beam. The joint structure effectively connects an embedded plate and the section steel rib, and is simple to manufacture, convenient to construct and reliable in force transmission.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a node structure and a construction method for connecting an auxiliary structure and a rigid concrete beam. Background technique [0002] With the progress of the times and the rapid development of the economy, various irregular over-limit high-rises continue to emerge. In order to effectively utilize the height of the building and optimize the building shape, the structural form will preferably use a stiff concrete structure. However, the cross-sectional dimensions of stiffened structural beams and columns are limited, and the cross-sectional dimensions of steel frames in stiffened concrete beams and columns continue to increase and thicken, making the anchorage connection space smaller and smaller, and the impact on the embedded parts of external auxiliary structures is also greater. bigger and bigger. On the other hand, since the auxiliary structures such as cu...

Problems solved by technology

On the other hand, since the auxiliary structures such as curtain walls and steel bridges are designed, processed and installed by relevant professional manufacturers, they are not synchronized with the design of stiffened concrete structures. Usually, the corresponding auxiliary structures are installed after the main structure is completed. If the burial is not in place, the post-installation company can only use post-planting reinforcement anchorage, which will inevitably cause structural damage to the rigid concrete structure, and the limited pre-embedded space also leaves a safety hazard for the auxiliary structure
