Problems solved by technology

[0002] When the outdoor ambient temperature changes, the indoor ambient temperature will also change accordingly, and the temperature of the inner partition wall board as an indoor space partition will also increase or decrease accordingly, and the resulting temperature difference stress fluctuation will cause the inner partition wall board to shrink and deform , resulting in cracking at the connection between the inner partition wall and the main structure of the building or at the connection between the inner partition and the inner partition, which affects the apparent quality of the building

Abstract

The invention discloses a prefabrication method of a temperature-changed-shrinkage resistant inner partition plate for a building. The method comprises the following steps: firstly, preparing concrete, coal ashes for commercial concrete, sand and gravel particles, acetophenone phase-change material microspheres, water and a concrete foaming agent; respectively stirring the materials evenly for three times; pouring a mold, hardening and conserving; and evenly and effectively distributing the acetophenone phase-change material microspheres and foam into a wall body of the inner partition wall plate. The inner partition plate obtained by the prefabrication method disclosed by the invention has the performance of resisting temperature-changed shrinkage, and is small in deformation in use; and the indoor apparent quality of the building can be improved.

Description

technical field [0001] The invention relates to the field of prefabrication of inner partition wall boards for buildings, and in particular provides a prefabrication method for inner partition wall boards of anti-temperature change and shrinkage for buildings. Background technique [0002] When the outdoor ambient temperature changes, the indoor ambient temperature will also change accordingly, and the temperature of the inner partition wall board as an indoor space partition will also increase or decrease accordingly, and the resulting temperature difference stress fluctuation will cause the inner partition wall board to shrink and deform , resulting in cracking at the connection between the inner partition wall panel and the main structure of the building or at the joint between the inner partition wall panel and the inner partition wall panel, which affects the apparent quality of the building. Contents of the invention [0003] The object of the present invention is to...
