Lightweight concrete block structure

Abstract

A lightweight concrete block structure, belonging to the technical field of building structures, includes a block body, where L-shaped connecting portions are symmetrically provided at both sides of the block body in a vertically mirrored configuration, left and right adjacent connecting portions are interlocked, and an auxiliary block or a damping structure is detachably connected between adjacent connecting portions; a positioning groove is formed in the bottom of the block body, and positioning protrusions that are in contact with two ends of the positioning groove are provided at both sides of the top of the block body; the positioning protrusions are each provided with a grouting slot extending downward through the block body, a longitudinal steel bar is arranged in the grouting slot and extends upward through an adjacent block body, and a fastener is arranged between adjacent longitudinal steel bars; and a transverse steel bar is arranged between horizontally adjacent longitudinal steel bars. The purpose is to solve the problems of easy misalignment between blocks during pouring and low seismic performance due to the fact that existing blocks lack a fixed structure.
