Embodiment Construction

[0038] Examples see figure 1 As shown, this air duct structure is located in the reserved opening of the main structure, and is composed of a group of prefabricated concrete air duct units 1 vertically assembled sequentially, and the joint positions of adjacent precast concrete air duct units 1 are supported by The supporting part 2 is connected between the upper precast concrete air duct unit and the lower precast concrete air duct unit, and is connected with the main structure 5 on the side. The main structure includes floors and walls.

[0039] see figure 2 As shown, the supporting member 2 is a closed ring, and its longitudinal section is H-shaped, including an inner ring plate and an outer ring plate arranged vertically in parallel and spaced apart, and a horizontal ring plate horizontally connected between the two, wherein the horizontal ring The plate divides the inner ring plate and the outer ring plate into an upper socket and a lower socket.

Abstract

Disclosed are an air channel structure and a construction method thereof. The structure is located in a reserved hole of a main structure, and is assembled sequentially by a set of precast concrete air channel units in a vertical direction. The joint positions of the adjacent precast concrete air channel units are connected through supporting members. Each supporting member is supported correspondingly between an upper precast concrete air channel unit and a lower precast concrete air channel unit, and is connected with the main structure on the side. According to the invention, the air channel structure is spliced by the precast concrete air channel units, the precast components have an uniform forming effect, the on-site masonry process is reduced, the construction efficiency is high, the connection effect is good, the overall integrity of the air channel is achieved, and the sealing performance of the joint positions of the air channel is ensured at the same time. On-site masonry process is eliminated, processes such as form bracing and a large number of concrete pouring are unnecessary, the construction efficiency is high, the construction pollution is small, the forming effectof the air channel structure after construction is good, the construction cost is low, and the input of manpower and material resources is greatly reduced. The air channel structure and the construction method thereof can be widely used in air channel installation and construction.

Description

technical field [0001] The invention relates to the field of building ventilation engineering, in particular to a ventilation structure and a construction method thereof. Background technique [0002] As a channel for air circulation in the building, the air duct is generally made of concrete, bricks and other materials. However, in many projects at present, due to the narrow space and limited space for air duct construction, it is not conducive to on-site construction; and for on-site construction, the efficiency of masonry construction is low and the construction quality is difficult to guarantee: for example, the diameter of the air duct is inconsistent, resulting in sudden expansion or reduction ; Or the verticality is deflected, so the air duct forming effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide an air duct structure and its construction method, to solve the technical problems of unstable air duct install...
