Chute damping device for concrete pouring and mounting and using method thereof

Abstract

The invention discloses a chute damping device for concrete pouring and a mounting, and a using method of the chute damping device. The chute damping device is formed by connecting a plurality of chute dampers through flanges. Each chute damper comprises a chute barrel (3), flanges (2) and damping flow guide steel plates (1), wherein the damping flow guide steel plates (1) are welded in the chutebarrel (3), and the included angle between the damping flow guide steel plates (1), the inner wall of the chute barrel is 45 degrees, the two damping flow guide steel plates arranged in each chute barrel are respectively arranged on two opposite inner wall surfaces and are perpendicular to each other, and a distance between welding seams is 1m; the flanges are welded to the two ports of the chutebarrel respectively, and every two adjacent chute dampers penetrate through flange bolt holes (5) through bolts to be connected; a steel bar lifting lug (4) is welded at the end part of the chute barrel (3). The chute damping device can effectively guide and buffer the falling impact force of concrete; and meanwhile, the construction technical specification requirement that a free falling height of the concrete does not exceed 2 m is met by changing the falling direction of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete pouring in the construction industry, in particular to a chute damping device for concrete pouring and an installation and use method thereof. Background technique [0002] Concrete construction has always occupied a large proportion in the civil engineering industry. The traditional methods of concrete transportation in concrete construction mainly use tower crane tank transportation or pumping. These traditional methods are only suitable for small concrete volumes and small concrete dump heights. If it exceeds 2m, for the large-volume steel frame reinforced concrete structure, it is far from meeting the requirement that the concrete fall height does not exceed 2m. Usually, the chute to be used for concrete pouring is HDPE steel belt reinforced double-wall corrugated pipe, with different specifications and models. Usually it is appropriate to use 300mm, and the whole length is 12m. When in use, ...

[0002] Concrete construction has always occupied a large proportion in the civil engineering industry. The traditional methods of concrete transportation in concrete construction mainly use tower crane tank transportation or pumping. These traditional methods are only suitable for small concrete volumes and small concrete dump heights. If it exceeds 2m, for the large-volume steel frame reinforced concrete structure, it is far from meeting the requirement that the concrete fall height does not exceed 2m. Usually, the chute to be used for concrete pouring is HDPE steel belt reinforced double-wall corrugated pipe, with different specifications and models. Usually it is appropriate to use 300mm, the whole length is 12m, and the end of the corrugated pipe is tied with hemp rope when in use, and the operation is completed by vertical or horizontal transport machinery

[0003] According to the existing technical situation and the actual situation of pouring concrete in large-volume steel frame concrete structures, there are the following objective shortcomings: the length control of the HDPE steel belt reinforced double-wall corrugated pipe is not flexible enough, the length of the connection cannot meet the construction needs, and the inner wall corrugation is relatively shallow. Damping effect It is poor and cannot meet the requirements of the construction technical specification that the free fall height of concrete should not exceed 2m, and the connection between the end of the corrugated pipe and the vertical or horizontal transport machinery is relatively simple and easy to slip, posing a safety hazard
