A kind of fabric concrete composite block and preparation method

Abstract

The invention discloses a fabric concrete composite block and its preparation method. The concrete block is not easily damaged and cracked, has good frost resistance, high block compressive strength, no holes and pockmarked surface, smooth appearance, suppresses wall cracks, and makes the life of the wall as long as that of the wall. The age of the principal structure matches. The combined cutting block includes four uprights arranged to form the corners of a rectangular tube, a fabric tube that is wound and fixed on the uprights to form a rectangular tube-shaped structure, and fillers filled inside the fabric shell; the cross-section of the uprights is rectangular , the relative positions of the four columns are fixed to form a lattice core cage. The preparation method includes step 1, core cage preparation; step 2, fabric tube preparation; step 3, fabric tube filling, pressurized and vibrated compactly, so that the fabric fits the inner wall of the steel mold; step 4, curing and molding; curing to After the initial setting of the filler, remove the steel mold and continue curing until the filler is completely solidified to complete the production of the composite block.

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 ...

[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 often honeycombed and pockmarked, and edges are prone to be missing during transportation Dropping corners, high water absorption, poor frost resistance; surface plastering is prone to hollowing, ash falling, and cracks, and the wall is easily cracked, which seriously affects the use
