Control method of wall cracks based on temperature monitoring

Abstract

The invention relates to a temperature monitoring based crack control method for a wall body. The method comprises the steps of binding a reinforcement cage of the wall body at the set location on a bottom plate; arranging an electric heating device on the reinforcement cage; fixedly arranging a temperature sensor on the reinforcement cage in the width direction of the wall body; arranging a die plate of the wall body at the outer side of the reinforcement cage, wherein the die plate encircles a pouring space; pouring concrete into the pouring space; acquiring the temperature detected by the temperature sensor on real time during solidifying of concrete so as to generate real-time temperature; controlling the heat supply of the electric heating device as the real-time temperature lowers down so as to reduce the lowering speed of the real-time temperature. According to the method, the electric heating device is used for heating concrete and controlling the temperature lowering rate during the solidifying of concrete, so that temperature can smoothly lower during the solidifying of concrete, and thus the problem of crack during the solidifying of concrete can be effectively avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for controlling wall cracks based on temperature monitoring. Background technique [0002] In building construction, the wall formed by concrete pouring, due to the release of cement hydrothermal during the concrete solidification process after concrete pouring, makes the temperature of the poured wall rise, and when the temperature rises to the highest point, it will drop rapidly , in the process of temperature change, the concrete wall has experienced the process of thermal expansion and contraction. Generally, the wall is poured on the base plate, and the base plate structure has been formed. During the temperature drop of the poured concrete wall (that is, the process of wall shrinkage), due to the constraints of the base plate structure, cracks will appear on the surface of the wall. [0003] In order to reduce the surface cracks of the concrete wall, the exist...
