Problems solved by technology

[0004] The purpose of the present invention is to provide a safety performance test device and test method for pre-embedded steel pipes in concrete construction, which can solve the problem that the existing range hood air intake cover is fixed on the outside of the range hood, and the cooking fumes are directly connected to the air intake cover during the cooking process. Contact, oil and impurities are directly attached to the outside, it is difficult to clean, and after a long time, the air intake cover is easily damaged and the service life is short

Abstract

The invention discloses a safety performance testing device for pre-embedded steel pipes in concrete construction, which comprises a workbench, a frame and a sleeve. The workbench is fixedly connected with a frame. A hydraulic oil cylinder is directly installed, and the bottom of the hydraulic oil cylinder runs through the bottom of the frame and is connected with an extruded plate; the outer middle end of the extruded plate is provided with an annular groove along the circumferential direction. After the position of the steel pipe is fixed, turn the fastening bolt on the side of the sleeve to enter the inside of the threaded barrel, and limit the position of the inner ring so that the position of the inner ring is not easy to move. And the inner ring is fixed by fastening bolts, and different fixing forces can simulate various fixing conditions of the steel pipe in use, making subsequent tests more diverse and the results obtained more accurate.

Description

technical field [0001] The invention relates to a test device, in particular to a test device and a test method for the safety performance of pre-embedded steel pipes in concrete construction, belonging to the application field of steel pipe tests. Background technique [0002] Steel pipe is one of the common and commonly used building materials. In concrete pouring construction, steel pipes to be used are often pre-fixed to form a frame as a supporting beam, and then concrete is poured. In order to ensure that the steel pipe has good performance in use, it is often tested for performance before use. [0003] However, there are still some deficiencies in the existing detection devices for the safety performance of steel pipes in use. The existing steel pipe safety performance detection device has cumbersome steps to detect steel pipes, and the cost of the detection equipment is high. It is extremely inconvenient to use in a dirty environment on the construction site, and ca...
