Fabric concrete composite building block and preparation method

Abstract

The invention discloses a fabric concrete composite building block and a preparation method. The concrete building block is not prone to cracking, the frost resistance is good, the compressive strength of the building block is high, no hole or pitted surface exists, the appearance is smooth, wall cracks are inhibited, and the service life of a wall body to is enabled to be matched with the servicelife of a main structure. The composite building block comprises four upright posts which are arranged to form corners of a rectangular cylinder, a fabric cylinder which is wound and fixed on the upright posts to form a rectangular cylinder structure in a tensioned mode and a filler filling a fabric shell, the cross section of each upright post is rectangular, and the four upright posts are fixedrelative to each other to form a lattice type core cage. The preparation method comprises the following steps that step 1, the core cage is prepared; step 2, the fabric cylinder is prepared; step 3,the fabric cylinder is filled with the filler, pressing and vibrating for compaction are carried out, so that fabric adheres to the inner wall of a steel mold; and step 4, curing and molding are carried out, curing is carried out until the filler is initially set, the steel mold is removed, curing is carried out continuously until the filler is completely solidified, and the fabrication of the composite building block is completed.

Description

technical field [0001] The invention belongs to the field of civil engineering and assembly structures, and relates to building masonry materials, in particular to a fabric concrete composite block and a preparation method thereof. Background technique [0002] Blocks are one of the constituent materials of building walls and have advantages in fabrication, transportation and masonry. Building walls generally need to bear in-plane and out-of-plane loads, and require thermal insulation, sound insulation, frost resistance and durability. There should be no cracks during normal use, and the walls should be convenient for opening doors and windows and laying various pipelines. [0003] Existing aerated concrete blocks and lightweight aggregate blocks have the function of thermal insulation and sound insulation, but due to the large number of closed pores inside and low density, the strength of the blocks is low, and the appearance is mostly honeycomb pockmarked, which is prone ...
