Description

Adopt vertical through-hole to put into bamboo pole grout and consolidate hollow block structure

Technical Field

The utility model relates to a hollow block structure reinforced by placing bamboo poles into vertical through holes and grouting, and belongs to the technical field of seismic reinforcement of existing buildings.

Background

The technology of adopting the vertical through hole to arrange the bamboo pole to be grouted and reinforced the hollow block structure is a brand new anti-seismic reinforcing idea. According to the technology, bamboo poles are placed in the concrete hollow small-sized block masonry wall and pressure grouting is carried out, bamboo pole grouting is formed to carry out anti-seismic reinforcement on the concrete hollow small-sized block masonry structure, wide application conditions are created for the method for carrying out anti-seismic reinforcement on the masonry structure, and the prospect of practical application is shown.

SUMMERY OF THE UTILITY MODEL

The utility model provides a method for reinforcing a hollow block structure by placing bamboo poles in vertical through holes and grouting, namely a method for reinforcing a concrete hollow small block masonry structure by placing bamboo poles in the vertical through holes and performing pressure grouting.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a hollow building block structure adopting a vertical through hole for placing bamboo poles in grouting reinforcement comprises a wall body and bamboo poles; the wall body is of a concrete hollow block masonry structure; the bamboo poles are vertically and uniformly inserted into the wall body, C35 concrete is used for filling the hole of the hollow building block, a pneumatic propulsion grouting machine is used for pressure grouting, and the gap between the concrete hollow building block and the bamboo pole is filled with mortar; the overlapping length of the bamboo poles and the bamboo poles at the inner joint part of the wall body is not less than 200mm, the bamboo poles and the bamboo poles are overlapped and fixed at the inner joint part of the wall body by adopting a steel strand, and the lower ends of the bamboo poles are deep into the foundation; and arranging a steel bar net sheet outside the wall body, and spraying concrete.

Furthermore, the bamboo pole is a bamboo pole with a diameter of more than 20 mm.

Further, the bamboo poles are vertically arranged on each hollow building block.

Furthermore, a steel bar net piece is arranged outside the wall body, and concrete is sprayed.

Furthermore, the reinforcing mesh is formed by welding phi 8 reinforcing steel bars.

The bamboo pole grouting reinforced hollow block structure adopting the vertical through hole and the construction method thereof adopt the following steps:

the method comprises the following steps: paying off a wall body needing to be reinforced by bamboo pole grouting according to a design drawing, and vertically and uniformly arranging holes along the longitudinal wall direction;

step two: inserting bamboo poles into the holes of the hollow building blocks, and arranging the bamboo poles in the wall;

step three: adjusting the lower ends of the bamboo poles to be deep into the foundation, and filling the opening of the hollow building block with C35 concrete;

step four: adopting a pneumatic propulsion grouting machine to perform pressure grouting, and grouting the gap between the concrete hollow block and the bamboo pole with mortar;

step five: and meanwhile, a reinforcing mesh is arranged outside the wall body, and concrete is sprayed.

Has the advantages that:

the utility model can effectively improve the crack resistance and shear resistance of the wall, inhibit the cracking of the wall, inhibit the development of cracks and improve the seismic resistance of the masonry structure, and particularly can effectively improve the seismic bearing capacity of the existing masonry building for seismic reinforcement.
