Abstract

The invention discloses a construction technology of a high-precision reinforced concrete reaction wall. The construction technology comprises the following steps of: a, laying a pedestal cushion layer, and paying off and positioning a pedestal loading slot on the pedestal cushion layer; b, constructing and calibrating a positioning steel frame of the pedestal loading slot; c, binding reaction wall pedestal reinforcing steel bars and reaction wall vertical reinforcing steel bars; d, fixing and calibrating the loading slot; e, erecting a pedestal template; f, performing concrete casting on a reaction wall pedestal; g, binding reaction wall reinforcing steel bars, and placing a loading hole; h, vertically and horizontally adjusting the loading hole; i, erecting a reaction wall template; and j, performing concrete casting on the reaction wall. By using processing equipment of the loading hole, the processing shaping precision of the loading hole is effectively guaranteed; the welding deformation is reduced; the vertical degree of the loading hole is guaranteed; the mass production can be performed, and the working period is saved. By the technology in the invention, the construction precision is easily controlled.

Description

technical field [0001] The invention relates to a construction technique of a high-precision reinforced concrete reaction wall for a structural mechanics laboratory, which is suitable for the construction of a reaction wall with channel steel loading slots and loading holes, and belongs to the field of main body construction of building engineering structures. Background technique [0002] The reaction wall is an important facility for pseudo-static or pseudo-dynamic tests of various structural components, structural materials and structural systems in engineering mechanics laboratories, usually including two parts: the reaction wall pedestal and the loading wall, which are pre-buried in the loading wall The error control of the loading hole and the loading groove in the reaction wall pedestal is very strict, requiring the surface flatness error of the loading groove ≤ 3mm, the axis deviation ≤ 1.5mm; the loading hole installation flatness error ≤ 1.5mm, and the center distan...
