Building structure for large-area air duct hoistway of factory building

Abstract

The large-area air duct shaft building structure comprises a plurality of steel beams, and the steel beams are laid in a crossed mode in the transverse direction and the longitudinal direction to form a net-shaped structure with a plurality of installation cavities. A floor slab is arranged in the mounting cavity, a connecting assembly used for connecting the floor slab and the steel beam is arranged in the floor slab, the connecting assembly comprises an upper abutting block and connecting rods, the multiple connecting rods slide on the side walls, facing the steel beam, of the periphery of the mounting cavity, and the ends, close to each other, of the connecting rods are located in the center of the floor slab; connecting holes matched with the connecting rods in an inserted mode are formed in the side wall of the steel beam, and when the upper abutting block is located between the connecting rods, the connecting rods penetrate through the side wall of the floor slab to be inserted into the connecting holes. A first reset assembly is arranged in the floor slab and can drive the connecting rod to retract into the floor slab when the upper abutting block is away from the connecting rod, and an adjusting assembly used for adjusting the position of the upper abutting block is further arranged in the floor slab. The device has the effect of providing convenience for workers to build the air duct hoistway.

Description

technical field [0001] The present application relates to the technical field of building air duct shafts, in particular to a large-area air duct shaft building structure of a factory building. Background technique [0002] In the construction of the factory building, the air duct shaft is one of the important components. Through the air duct shaft, the factory building can be ventilated and gas exchanged. [0003] Nowadays, most of the air ducts are built above the roof of the factory building, and the roof is mostly made of concrete. Because the entry position of the tenant cannot be determined during the construction of the factory building, it is usually impossible to determine the position of the well entrance in advance. After that, according to the location of the tenant, determine the location where the air duct will enter the factory building, and then open a well opening on the roof, and then pass the air duct into the factory building from the well opening.

AI Technical Summary

Problems solved by technology

[0003] Nowadays, most of the air ducts are built above the roof of the factory building, and the roof is mostly made of concrete. Because the location of the tenant's entry cannot be determined during the construction of the factory building, it is usually impossible to pre-determine the location of the well entrance, and the tenant can only move into the factory building. Finally, according to the tenant's occupancy position, determine the position where the air duct enters the factory building, open the well opening on the roof, and then pass the air duct from the well opening into the factory building

[0004] In view of the above-mentioned related technologies, the inventor believes that the existing roof is made of concrete, and it is extremely difficult to dig the well opening, which requires a lot of construction operations by the staff, and there is a defect that the construction of the air duct well is inconvenient for the staff
