Abstract

The invention relates to a loading hole unit welding tool for a reaction wall and a reaction pedestal. The loading hole unit welding tool comprises a tool support. The tool support is provided with abottom support and a counterweight pressure support. A plurality of lower loading hole locating structures are distributed on the bottom support. Upper loading hole locating structures corresponding to the lower loading hole locating structures are distributed on the counterweight pressure support. The upper loading hole locating structures and the lower loading hole locating structures each include a locating plane making contact with the outer plate surface of each loading hole end plate. Each locating plane is provided with a cylindrical locating protrusion used for being matched with a center hole of each loading hole for locating plugging-in mounting. The locating planes of all the lower loading hole locating structures are located in the same plane. The locating planes of all the upper loading hole locating structures are located in the same plane. The loading hole unit welding tool for the reaction wall and the reaction pedestal, provided by the invention, can weld the multipleloading holes into a loading hole unit.

Description

technical field [0001] The invention relates to a loading hole unit welding tool for a reaction wall and a reaction pedestal in a structural laboratory. Background technique [0002] In the structural laboratory, the reaction wall and the reaction pedestal are an important part of the pseudo-static test. Existing reaction walls and reaction pedestals such as figure 1 As shown: the reaction wall 1 and the reaction pedestal 2 are distributed with a plurality of loading holes 11 and 21 arranged in an array. The loading holes 11 and 21 are made of steel pipes and steel plates arranged at both ends of the steel pipes. The steel plates can be called Load hole end plate and pre-embedded in concrete. In the design requirements, the loading holes 11 and 21 pre-embedded in the concrete of the reaction wall 1 and the reaction pedestal 2 are designed with a relatively large horizontal thrust of 1000kN, and within the range of two meters, the distance between the centers of any two loa...
