Embodiment Construction

[0019] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0020] The present invention proposes a reasonable and effective wall maintenance method, which can effectively reduce the hydration heat temperature stress of the wall and reduce the cracking of the wall. The specific steps of the method are as follows:

[0021] combine figure 2 , image 3 As shown, first debug the wireless thermometer, connect the wireless thermometer to the computer to keep the distance between the two within 500 meters, and then install the temperature sensor of the debugged wireless thermometer before the concrete wall 1 is poured. Installed at different heights and thicknesses inside the wall (reinforcement cage to be poured) 1, the temperature inside the concrete is measured by a temperature sensor, the formwork 2 is installed outside the reinforcement cage to...

Abstract

The invention provides a wall maintaining method based on automatic temperature measurement and temperature stress reduction, which comprises the following steps: before casting the concrete wall, mounting temperature sensors of a wireless thermodetector at positions with different heights and different thicknesses inside the to-be-cast concrete wall; after casting the concrete, reading the temperature in the concrete through the temperature sensors; based on the read temperature, carrying out the following operations: spraying water to the outer side of the template during the temperature rising process as heat is released due to hydration heat of cement at the early stage of the concrete wall; when the temperature inside the wall is raised to a peak value, stopping spraying, covering thin film on the outer side of the concrete wall to keep temperature of the wall, and delaying the rate of temperature fall of the wall. The structure is simple, and easy to operate. The method can actively protect the wall from temperature crack at the early stage by virtue of spraying the concrete and covering the thin film on the surface to control the temperature inside the concrete, and meanwhile improve the construction quality of the wall.

Description

technical field [0001] The invention relates to a wall body maintenance method based on automatic temperature measurement, and aims to reduce the early hydration heat temperature stress of the wall body and reduce the cracking of the wall body through a correct and reasonable wall body body maintenance method. Background technique [0002] The temperature cracks of concrete exterior walls are serious on many construction sites at present. combine figure 1 As shown, the reasons for the cracking of the concrete exterior wall are: 1. In the early stage, due to the release of the cement hydration heat, the concrete wall will cause the temperature to rise and cause volume expansion. After the cement hydration heat release rate slows down, due to the Heat dissipation will cause the temperature to drop and cause the volume of the concrete wall to shrink; 2. The expansion and contraction of the concrete wall will be restricted by the surrounding components such as the bottom plate ...
