Description

Technical Field

[0001] The present invention relates to the technical field of concrete temperature measurement, and in particular to a concrete bottom plate temperature measurement device and a temperature measurement method. Background Art

[0002] The concrete base plate plays an extremely critical role in the bridge structure. It is an important component of the lower edge of the box section and directly bears the positive and negative bending moments generated by the bridge during operation. As the main stress-bearing part, the size and strength design of the base plate are crucial. In reinforced concrete bridges, the base plate must not only ensure sufficient size to assemble the required tensile steel bars, but also ensure that these steel bars have sufficient concrete protection layer to effectively resist the tensile stress caused by the bending moment and ensure the long-term stability and safety of the bridge. In prestressed reinforced concrete bridges, the design of the base plate is more particular. It needs to provide a large enough pressure-bearing area to meet the requirements of the bridge for compressive performance during the operation stage. It not only helps to evenly transfer prestress and improve the overall stress performance of the bridge, but also ensures the durability and bearing capacity of the bridge in long-term use. Therefore, the design and construction quality of the concrete base plate are directly related to the overall performance and life of the bridge structure.

[0003] During the construction of the existing concrete floor, the construction temperature is usually controlled to ensure the construction quality of the concrete. When controlling the temperature, the temperature of the concrete needs to be detected. For example, Chinese Patent Publication No. CN115538442A discloses "a method for constructing a concrete floor", which improves the stress performance of the concrete by setting a bottom layer of concrete under the concrete floor. At the same time, a water pipe is set in the bottom layer of concrete. Controlling the water pipe can ensure the temperature field of the bottom structure of the concrete floor, avoid excessive temperature difference between the concrete floor and the bottom layer of concrete caused by severe cold weather, and cause temperature damage. By controlling the water inlet temperature of the water pipe, the casting performance of the concrete floor can be effectively improved to ensure the construction quality. The alarm device is connected to the temperature measuring device, the first temperature sensor and the second temperature sensor of the water inlet. The alarm device can alarm the maximum temperature and the minimum temperature exceeding the limit and give an alarm signal. After the concrete floor is cured to the design strength, the communication lines of the first temperature sensor and the second temperature sensor are cut off, and the casting of the concrete floor is completed.

[0004] However, in actual use, the communication line of the temperature sensor is separated from the alarm device and the detection device by cutting. When the alarm device and the detection device are used for temperature detection at other construction sites, they need to be rewired, which is not only troublesome to operate, but also prone to short circuits after wiring, affecting use. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the communication line of the temperature sensor is cut off after use, and the detection device needs to be rewired when performing temperature detection in other construction sites, which is prone to short circuit, and a concrete bottom plate temperature measuring device and temperature measuring method are proposed.

[0038] In the present invention, a connector 7 is provided to connect with the temperature sensor for convenient assembly and disassembly. The connector 7 is a GX16 male-female butt-jointed aviation plug or socket with wires, and can also be other types of plugs or sockets. The position of the connector 7 can be adjusted by providing a winding mechanism 5, so that the temperature sensor can be placed in a more remote area, and temperature measurement can also be performed on a large area of ​​concrete floor construction site, thereby increasing the scope of application. A storage grid 45 is provided to store multiple temperature sensors for convenient access at any time.

[0039] Furthermore, in this embodiment, the wire-reeling mechanism 5 includes a winding wheel 51 rotatably disposed in the inner cavity 44, a rotating shaft 52 rotatably connected to the winding wheel 51 is fixedly disposed in the inner cavity 44, a threading hole 441 is opened on the inner cavity 44, and when the connector 7 is moved, the wire moves outward along the threading hole 441, driving the winding wheel 51 to rotate and release the wire.

[0040] In this embodiment, a torsion spring 53 is arranged between the rotating shaft 52 and the winding wheel 51. As the winding wheel 51 rotates, the torsion spring 53 will undergo elastic deformation.
