Construction method of newly added shock insulation layer with brick-concrete structure

Abstract

The invention relates to a construction method of a newly added shock insulation layer with a brick-concrete structure. The construction method comprises the steps that positioning and wire laying are pre-arranged for the shock insulation layer; the earthwork is excavated indoors and outdoors, the wall body below the pre-arranged shock insulation layer is cleared; the wall body below the pre-arranged shock insulation layer is reinforced; the wall body of the pre-arranged shock insulation layer is cut by static force and holes are opened, a temporary steel support is mounted on the location of the holes in the wall body; the wall body between the temporary steel support is torn down by segments; the lower joist beam steel ribs are bound on the reinforced wall body, the lower joist beam side mould is arranged in a supporting mode, the lower pre-buried plate is fixed, and concrete is casted to form a lower joist concrete beam; a rubber shock insulation mat is arranged on the lower joist concrete beam; an upper joist beam template is arranged in a supporting mode, and upper beam steel ribs are bound, an upper pre-buried plate is mounted, and concrete is casted on the rubber shock insulation mat to form an upper joist concrete beam; when the concrete intensity of the upper and the lower joist beam concrete reaches the designed value, the temporary steel support is cut and removed, and the construction of the shock insulation layer is complete. The construction method is simple and quick, less in project amount and high in safety.

Description

technical field [0001] The invention relates to the technical field of building reinforcement, in particular to a construction method for adding a shock-isolation layer to an existing brick-concrete structure. Background technique [0002] The earthquake damage of the Wenchuan Earthquake shows that the overall seismic performance of masonry structures is poor, the ductility is low, and brittle failures are prone to occur, which can easily cause large casualties and property losses. The early multi-storey masonry structures in my country had problems such as complex structure types, unreasonable structural systems, poor seismic capacity and seismic measures. The traditional seismic reinforcement methods mainly include: concrete slab wall reinforcement method of brick masonry, reinforcement method of newly added ring beam structural column, reinforcement method of adding seismic wall, reinforcement method of adding support, reinforcement method of setting external frame, etc. ...
