Construction method of inverse force wall and inverse force dado

Abstract

The invention discloses a reaction wall and a construction method of a reaction dado; a plurality of loading holes with a certain hole diameter or hole distance are pre-embedded in the reaction wall and the reaction dado; the construction method mainly utilizes a tailor-made loading hole positioning mould to position each loading hole; a plurality of loading hole positions meeting the standard ofthe loading hole diameter and hole distance are arranged on the loading hole positioning mould, then matched with positioning stuffs or positioning plugs; therefore, the loading holes can be positioned conveniently and accurately, then fixed; unlike the prior method which measures while fixing, therefore the construction method can greatly improve the hole distance precision of each loading hole and reduce construction man-hours.

Description

Construction method of reaction wall and reaction pedestal technical field The invention relates to a construction method, in particular to a construction method of a reaction force wall and a reaction force pedestal. Background technique In the structural laboratory, the reaction wall and the reaction pedestal are an important part of the pseudo-static test. As shown in Fig. 1, a number of loading holes 11, 21 are densely arranged on the reaction wall 1 and the reaction platform 2. The loading holes 11, 21 are made of steel pipes and steel plates, and are pre-embedded in concrete. According to the design requirements, the design horizontal thrust of the loading holes 11 and 21 pre-embedded in the concrete of the reaction wall 1 and the reaction pedestal 2 is 1000kN, and the single hole pre-embedded in the concrete of the reaction pedestal 2 has a pull-out capacity of 1000kN. And within the range of two meters, the distance error between the centers of any two loading hol...

Problems solved by technology

In this construction method, the error of the previous hole will be added to the next one, and the error will also be caused when the welding is fixed, so it must be adjusted continuously during the construction process, resulting in low precision, and the construction time is long. It will also displace the loading hole and affect the accuracy
