The method comprises the following steps:
the invention also provides a temperature measurement method of the concrete in the steel plate shear wall, which comprises the following steps:
and step S1, dividing a plurality of temperature measuring areas along the longitudinal direction and the transverse direction according to the structure of the steel plate shear wall, and determining a plurality of temperature measuring points according to each temperature measuring area.
Specifically, since the temperature distribution inside the concrete is mainly related to the distance between the concrete and the steel plate, the deeper the measurement depth, the higher the embedding requirement of the temperature measuring unit 1. According to the structure of the steel plate shear wall, the steel plate shear wall can be divided into 4 temperature measuring areas in the longitudinal direction: an upper temperature sensing zone a, a middle temperature sensing zone b, a lower temperature sensing zone c and a bottom temperature sensing zone d (as shown in fig. 5). Wherein: the bottom of the upper temperature measuring area is provided with a steel plate 7 with a hole 5; the upper end and the lower end in the middle temperature measuring area are both provided with steel plates 7 with holes 5; the upper end and the lower end of the lower temperature measuring area are both steel plates provided with holes 5; the upper end of the bottom temperature measuring area is provided with a steel plate 7 with a hole 5, and the lower end is poured concrete.
The laterally distributed temperature measurement areas include: corner temperature measurement area e, edge temperature measurement area f and interior temperature measurement area g. The corner temperature measuring area is an area surrounded by steel plates on two or three sides; the edge temperature measuring area is an area surrounded by steel plates on one side or two sides; the inner temperature measuring area is an area surrounded by no steel plate.
In specific implementation, according to actual temperature measurement needs, longitudinal temperature measurement points are selected first, and then transverse temperature measurement points are selected. Each temperature measuring area can be provided with one or more temperature measuring points.
In order to obtain more complete data, the temperature measurement component 1 should be extended to all longitudinal temperature measurement areas, but considering that the length of the steel plate wall is long and is about 3-10 m, temperature measurement points are not well distributed, the temperature of a bottom temperature measurement area can not be measured, the temperature of other temperature measurement areas is referred to, and in order to obtain more effective data, the position of the temperature measurement component 1 should be extended to the middle position of the lower temperature measurement area. When selecting the transverse temperature measuring points, at least one temperature measuring point is selected from the corner part, the edge part and the inner temperature measuring area respectively to measure the temperature.
Step S2, determining the heights of a plurality of longitudinal temperature measuring points and the extending positions of a plurality of horizontal temperature measuring points according to the positions of the temperature measuring points, and determining the arrangement mode of the temperature measuring component 1 according to the heights of the longitudinal temperature measuring points and the extending positions of the horizontal temperature measuring points to finish the installation of the temperature measuring device.
Particularly, each vertical temperature measuring tube 11 is arranged in the hole 5 area inside the steel plate shear wall, the horizontal temperature measuring tubes 12 are adopted to horizontally extend to temperature measuring points, the number of the vertical temperature measuring tubes 11 is reduced, and meanwhile, complicated procedures that holes 5 need to be formed in the steel plate when the angle portion or the edge portion area is measured are avoided. In this embodiment, if the temperature measurement extension in the horizontal direction is required at different heights, a plurality of horizontal temperature measurement tubes 12 may be disposed on the side wall of the vertical temperature measurement tube 11.
Furthermore, when the temperature measuring component 1 of each temperature measuring device group is installed, the height of the temperature measuring component 1 is adjusted through the positioning piece 3, the horizontal displacement of the positioning piece 3 is adjusted through the telescopic clamp 2, the angle of the horizontal temperature measuring pipe 12 is adjusted through the rotation of the positioning piece 3, and then the extending position of the horizontal temperature measuring pipe 12 is adjusted.

After the temperature measuring device is positioned, pouring concrete into the steel plate shear wall, so that the pouring surface of the concrete is lower than the connecting part of the vertical temperature measuring tube 11 and the positioning piece 3, after the concrete is initially set, detaching the positioning piece 3 from the vertical temperature measuring tube 11, removing the positioning piece 3, taking down the clamping piece 22, only keeping the vertical temperature measuring tube 11 and the horizontal temperature measuring tube 12 at the bottom, and sealing the top opening end of the vertical temperature measuring tube 11 by using a sealing cover; so far, the temperature measuring component 1 is installed.
Furthermore, in order to prevent the impact in the concrete pouring process from influencing the position of the horizontal rod temperature measuring tube, a hoop locking device can be arranged between the positioning piece 3 and the surrounding hoop 23, so that the relative displacement between the positioning piece 3 and the surrounding hoop 23 cannot be generated.
And step S3, introducing a plurality of temperature measuring wires into the corresponding temperature measuring components 1 for temperature measurement, taking out each temperature measuring wire after the measurement is finished, and sealing the openings of the temperature measuring components 1.
Specifically, when the temperature is measured, a temperature measuring line or other temperature measuring instruments can be inserted into the temperature measuring pipe for temperature measurement, or an automatic temperature measuring mode can be adopted, a temperature monitoring sensor is buried in the temperature measuring pipe, the acquisition frequency is set, temperature data are automatically transmitted, the mounting position of a data acquisition unit is 1-1.2 m higher than the upper surface of the concrete, and waterproof treatment is carried out. During specific testing, the position of the temperature measuring device can be moved along the longitudinal direction, and the temperature of temperature measuring points at different heights can be tested.
In order to accurately monitor the temperature of the concrete in the steel plate shear wall, the temperature test recording time is not less than 7 days, and is determined according to the temperature gradient in the concrete, the temperature difference between the concrete and the steel plate, and the temperature difference between the concrete and the outdoor temperature. The vertical distance between the longitudinal temperature measuring points is not more than 30-70 mm. And after the measurement is finished, the temperature measuring line is taken out, and the opening of the vertical temperature measuring tube 11 is sealed by a sealing cover to prevent other sundries from falling.
In this embodiment, the method may further include: and step S4, plugging the temperature measuring component 1 by grouting material. And after the temperature to be measured is finished, grouting the temperature measuring assembly 1 to enable the temperature measuring assembly 1 and the steel plate shear wall to be poured into a whole.
