Reaction box and construction method of reaction wall

Abstract

The invention discloses a construction method of a reaction box, comprising the following steps: staking and layout: firstly locating locations of loading holes located at four corners of a reaction pedestal of the reaction box, then locating locations of the locating holes at four corners of each grid according to the loading hole locations at the four corners of the reaction pedestal, and locating the other loading hole locations in the grid according to the locating hole locations at four corners of the grid; binding reinforcements; mounting locating molds of the loading holes; mounting and adjusting built-in fittings of the loading holes; mounting prestressed tendons, establishing the other templates of the reaction pedestal; casting concrete; and finishing the reaction box construction. By virtue of staking and layout from the whole to the local part, the accumulated error in the existing location is reduced, and the location mounting precision is improved. The invention further discloses a construction method of the reaction wall similar to that of the reaction box. The method does not need to improve the built-in fittings of the loading holes of the reaction wall, so that the mounting efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a reaction force box and a reaction force wall. Background technique [0002] The reaction wall test pedestal in the structural laboratory is a test facility for the research of pseudo-dynamic tests, etc. The reaction wall test pedestal includes two parts: the reaction box and the reaction wall. Among them, the reaction box is a cuboid located underground, and the reaction box is composed of a reaction platform, a rib wall, and a bottom plate from top to bottom; Reaction force. Thousands of evenly distributed loading hole embedded parts are pre-embedded in the reaction pedestal and the reaction wall of the reaction box. The loading hole embedded parts are made of steel pipe or steel plate, and the loading hole is formed after concrete pouring. [0003] The center spacing of the loading holes arranged in a matrix is ​​a certain value, and t...

AI Technical Summary

Problems solved by technology

[0004] The existing installation method of the loading holes of the reaction box is to adopt the method of adjacent successive positioning and installation, that is, one or a row of loading holes is first positioned on the reaction pedestal of the reaction box, and then according to the positioning of this or this row of loading holes. The next or next row of loading holes adjacent to each other, this method is prone to cumulative errors, resulting in low positioning accuracy of the loading holes, because the positioning of the loading holes of the reaction wall is repositioned according to the position of the loading holes of the reaction box, so There is also a cumulative error; for the installation of the loading hole of the reaction wall, the existing method needs to improve the embedded parts of the loading hole, that is, on the basis of the original design, each end of the embedded part of the loading hole is extended by a specific length, and Pull out the external thread on the extension part, and fix the embedded part of the loading hole on the channel steel bracket with nuts. This process causes a delay in the construction period and an increase in the comprehensive cost of labor, materials and machinery.
