Problems solved by technology

At present, there are few engineering structure laboratories with reaction walls in the country, and there is no special tool for adjusting the flatness of the loading holes of the reaction wall. Inefficient tools such as square steel pipes, wooden sticks, or jacks are basically used, which is laborious and ineffective. Relatively poor

Abstract

The invention provides a reaction wall loading hole inwards pressing tool. The reaction wall loading hole inwards pressing tool comprises a main screw rod, a top holding part, a cross rod, a first hook mechanism and a second hook mechanism, wherein an embedded nut is arranged in the cross rod; the main screw is in threaded connection to the embedded nut; one end part of the main screw is connected to the top holding part; two end parts of the cross rod are respectively connected to one end part of the first hook mechanism and one end part of the second hook mechanism; the top holding part is used for top holding a reaction wall loading hole. The reaction wall loading hole inwards pressing tool disclosed by the invention has the advantages of being high in efficiency, low in cost, and simple and convenient to manually operate.

Description

technical field [0001] The invention relates to a tool for internal pressure in a loading hole of a reaction wall. Background technique [0002] The reinforced concrete reaction wall is an important facility for quasi-static or pseudo-dynamic tests of various structural materials, structural components and structural systems in the engineering structure laboratory. The flatness control of the loading holes embedded in the reaction wall is very strict , Controlling the flatness of the loading hole is the key link to ensure the construction quality. At present, there are few engineering structure laboratories with reaction walls in the country, and there are no special tools for adjusting the flatness of the loading holes of the reaction walls. Inefficient tools such as square steel pipes, wooden sticks, or jacks are basically used, which is laborious and ineffective. Relatively poor. Contents of the invention [0003] The technical problem to be solved by the present inve...
