Problems solved by technology
The patent is still unable to achieve equipment recycling
[0004] To sum up, the deficiencies of the prior art are mainly: 1) equipment consumption is relatively large, recycling is not considered, or the recovery rate of equipment is very low
2) The temperature measurement method of the thermometer reading is not efficient. If the non-contact temperature measurement method is used, there is still a problem of temperature measurement lag and the accuracy is difficult to improve

Embodiment Construction
[0034] The present invention is described below in conjunction with accompanying drawing:
[0035] Such as Figure 1 to Figure 7 As shown, a concrete temperature measuring device provided by the present invention includes a base 1, a temperature measuring tube 21, a mounting part, a connector 6, a sensor 3, and a protective sleeve 5; the sensor includes a wire; The resistance temperature sensor or thermocouple sensor, and the resistance temperature sensor can specifically adopt a three-wire or four-wire platinum resistance temperature sensor.
[0036] The lower end of the temperature measuring tube is detachably connected to the base, such as threaded connection, etc. The lower end of the temperature measuring tube 21 can also be threaded with the base 1 through a solid sleeve 22, and the base can fix the temperature measuring tube during temperature measurement. The length is determined according to the thickness of poured concrete, and a mounting hole 23 is provided on the ...

Abstract
The invention discloses a concrete temperature measuring device, which comprises a base, a temperature measuring tube, a mounting part, a connecting piece, a sensor and a protective sleeve; the sensoris a temperature sensor and comprises a wire; the lower end of the temperature measuring tube is detachably connected with the base, and a mounting hole is formed in the temperature measuring tube; the mounting part comprises an mounting pipe, an mounting opening is formed in the pipe wall of the mounting pipe in the axial direction of the mounting pipe, the lower end of the mounting pipe is connected with a supporting base, and a supporting rod is arranged on the supporting base; an included angle between the supporting rod and the mounting pipe is about 30 degrees, and the sensor is detachably fixed on the connecting piece; when the sensor is fixed on the mounting part through the connecting piece, the outer diameter of the orthographic projection of the sensor and the mounting part issmaller than the inner diameter of the temperature measuring tube; when the sensor is mounted in the mounting hole, the sensor outside the temperature measuring tube is sleeved with the protective sleeve, and a low-melting-point plastic gasket is arranged between the protective sleeve and the mounting hole. The device can be recycled and is convenient to fix, temperature detection points at different positions can be set, and equipment consumption is reduced.
Description
technical field [0001] The invention belongs to the field of construction engineering civil construction and relates to a concrete temperature measuring device. Background technique [0002] The construction of mass concrete is in accordance with "Code for Mass Concrete Construction (GB50496-2009)", "Construction Standard for Mass Concrete (GB 50496-2018)" and "Technical Specifications for Temperature Measurement and Control of Mass Concrete (GB / T 51028-2015)". Temperature measurement must be carried out, and temperature control and necessary maintenance should be carried out based on temperature measurement. According to the specifications, each pouring block is tested on a symmetrical semi-axis, and each test axis should not be less than 4 testing points, and each point generally arranges 3-5 measuring points. Therefore, the temperature measurement points of a single mass concrete construction project range from dozens to hundreds. Usually the sensor is tied to the steel...
