Device and method for testing safety performance of pre-embedded steel pipe in concrete construction

Abstract

The invention discloses a device for testing the safety performance of a pre-embedded steel pipe in concrete construction. The device comprises a workbench, a frame and a sleeve; the workbench is fixedly connected with the frame, the interior of the frame is hollow, a hydraulic oil cylinder is vertically installed in the middle of the top of the frame, and the bottom of the hydraulic oil cylinderpenetrates the bottom of the frame and is with an extrusion plate; and an annular groove is formed in the middle end of the exterior of the extrusion plate in the circumferential direction. After theposition of the steel pipe is fixed, fastening bolts on the side surface of the sleeve are screwed into a threaded cylinder, an inner ring is limited, and the position of the inner ring is not prone to moving. The fastening bolts are used for fixing the inner ring, various fixing conditions of the steel pipe in use can be simulated through different fixing forces, subsequent tests are more diversified, and obtained results are 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...

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
