Problems solved by technology

[0004] This comparison document can prefabricate steel bars and other structures on the prefabricated reverse stone concrete hanging slab, which can reduce the manufacturing cost of the prefabricated reverse stone concrete hanging slab. After the stone is poured with the concrete, the stone and the concrete will be bonded Adhesives are bonded together, but the expansion coefficients of concrete and stone are different, and the concrete density is uneven when the concrete is poured, and the expansion degree of different parts is also different, so that the concrete will cause damage to the stone during the process of thermal expansion and contraction. Pulling, the wall will crack in the stone during long-term use, affecting the beauty of the stone and the stability of the wall

Embodiment 1

[0028] Embodiment 1: A kind of stone anti-beating process that reduces cracks, including:

[0029]Step 1, stone selection, choose arc stone, the arc of the stone is the same as the arc of the column to be formed, choose the size and specification of the stone according to the column to be made, and use granite and marble as the best types, and can Choose some other stones with better color, check the stones when purchasing, remove some stones with cracks, weathering and impurities, and reduce the collision of stones in the process of transportation and handling of the selected stones.

[0030] Step 2, draw a line on the back of the stone, measure and mark the hole position, the drilling machine drills the inner surface of the stone according to the marked hole position, and each stone is at the four corners or the center of the stone Open 4-5 pairs of holes, the depth of the drill bit should be 15-25mm, then inject the glue-planting bars into each hole, and then directly inser...

Abstract

The invention discloses a stone reversing-laying technology capable of reducing cracks. According to the technical scheme, the technology comprises the following steps that S1, stone is selected; S2,lines are drawn on the back surface of each stone, and hole drilling is conducted; S3, a surface protection agent is applied to the back surface of each stone; S4, a mold release agent is applied to molds positioned at a mold platform; S5, lines are drawn on the interior of each mold, and elastic partitioning strips are pasted to the lateral wall of each stone; S6, the molds are partitioned; S7, reinforcement skeletons are poured in different areas; S8, after pouring, concrete in all areas is maintained with water and heat; S9, a mold plate is disassembled; S10, the poured concrete is subjected to strength detection, and S11, the surface of a stand column is cleaned with water. The technology achieves the technical aim of reducing cracks of the stone in the process of hot expansion and cold shrinkage.

Description

technical field [0001] The invention relates to the field of concrete processing and production, more specifically, it relates to a stone counter-beating process for reducing cracks. Background technique [0002] The stone counter-beating process is to beat the decorative stone for the exterior wall of the building into the concrete in the factory to form an integrated building prefabricated component, so that the stone is positioned accurately, the surface is firm, and the integrated assembly can greatly improve the construction progress. [0003] In the prior art, the patent application number that can be referred to is the patent document CN106968375A, which discloses a method for installing a prefabricated reverse stone concrete hanging slab. Compared with the existing installation method, the installation process is no longer an irreversible one-time Engineering, in the final inspection process, if the verticality is found not to meet the requirements, it can be reinsta...
