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

Embodiment Construction

[0041] Such as figure 2 As shown in Fig. 1, the main construction process of the reaction pedestal of the present invention is as follows: formwork installation and positioning and line drawing - using a special loading hole positioning mold to install positioning cakes on the formwork - installing loading holes and positioning Upper end surface - fix the loading hole and install the steel bar binding - pour concrete - remove the formwork. The specific instructions are as follows:

[0042] 1. Template installation, positioning and drawing lines (as shown in Figure 3):

[0043] Install the fixed template 3, and utilize the support system (not shown) to support the template 3; then control the surface flatness of the template 3, and the flatness of the template 3 directly determines the flatness of the lower surface of the counter force pedestal 2 , which is also the premise to ensure the flatness of the upper surface of the counter force pedestal 2; then draw vertical and hor...

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 of the 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

technical field [0001] 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 [0002] 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 holes is less than ±1mm. The reaction wall, rea...
