Embodiment 1

[0039] Such as Figure 1-7 As shown, a concrete coagulation strength detection device includes: a base 1; ribs are provided on the outer surface of the base 1, the strength of the base 1 is increased by setting the ribs, and a support 2 is provided on the upper side of the base 1; The support member 2 is provided with a rotating mechanism 4; the rotating mechanism 4 is connected with the transmission structure 7; the transmission mechanism 7 is connected with the power mechanism 6, and the power mechanism 6 drives the transmission mechanism 7 to rotate; the rotation mechanism 4 A lifting mechanism 5 is arranged inside; the lifting mechanism 5 runs through the support member 2 and the base 1, and when the rotating mechanism 4 rotates, the lifting mechanism 5 can move up and down; the lower end of the lifting mechanism 5 is provided with a square plate 10; the square plate 10 is provided with a clamping mechanism 11, and the clamping mechanism 11 is used to clamp the concrete sa...

Embodiment 2

[0048] The difference from Example 1 is that, if Figure 1-7 As shown, a concrete coagulation strength detection device includes: a base 1; ribs are provided on the outer surface of the base 1, the strength of the base 1 is increased by setting the ribs, and a support 2 is provided on the upper side of the base 1; The support member 2 is provided with a rotating mechanism 4; the rotating mechanism 4 is connected with the transmission structure 7; the transmission mechanism 7 is connected with the power mechanism 6, and the power mechanism 6 drives the transmission mechanism 7 to rotate; the rotation mechanism 4 A lifting mechanism 5 is arranged inside; the lifting mechanism 5 runs through the support member 2 and the base 1, and when the rotating mechanism 4 rotates, the lifting mechanism 5 can move up and down; the lower end of the lifting mechanism 5 is provided with a square plate 10; the square plate 10 is provided with a clamping mechanism 11, and the clamping mechanism 1...

Embodiment 3

[0051] The difference from Embodiment 1 is that during the concrete measurement process, in order to allow the concrete to be fully cooled, the volume V inside the base, the thickness D of the base plate, and the thickness d of the cold insulation layer satisfy the following relationship:

[0052] d =α·V / D+M;

[0053] Among them, the unit of D and d is cm; α is the correlation coefficient, the value range is 0.005-0.025, and the unit of V is cm 3 ; M is the compensation parameter, the value is 1-3. When α is less than 0.005, the thickness of the cold insulation layer is low, the cold insulation effect is poor, and the cooling time is long; when α is greater than 0.025, the thickness of the cold insulation layer is large, and the temperature in the base 1 is low. When cooling the concrete sample 15, If the device is kept at low temperature for a long time, the material of the device becomes brittle, which reduces the strength of the device, and the device is prone to damage an...

Abstract

The invention discloses a concrete setting strength detection device. The device comprises a base, wherein a supporting piece is arranged on the upper side of the base; a rotating mechanism is arranged in the supporting piece; the rotating mechanism is connected with a transmission structure; the transmission mechanism is connected with a power mechanism; a lifting mechanism is arranged in the rotating mechanism; the lifting mechanism penetrates through the supporting piece and the base; a square plate is arranged at the lower end of the lifting mechanism; a clamping mechanism is arranged on the square plate; a tension sensor is arranged on the lifting mechanism; the tension sensor is electrically connected with a controller; a connecting pipe is arranged on the base; the connecting pipe is communicated with the interior of the base; and a condensation tank is arranged at the other end of the connecting pipe. By arranging the condensation tank, the condensation gas is contained in the condensation tank, and a low-temperature environment can be provided, so that the strength of the concrete is detected in the low-temperature environment, and the requirement for detecting the strength of the concrete in actual operation is met.

Description

technical field [0001] The invention belongs to the technical field of construction engineering detection equipment, and in particular relates to a concrete coagulation strength detection device. Background technique [0002] After the construction of the project is completed, the strength of the coagulation needs to be tested during the completion acceptance, so as to judge whether the appropriate amount of the project meets the relevant requirements. The strength of concrete has a great influence on the quality of the project. In the construction of the chemical industry, some of the industrial plants are full of chemical raw materials, and their leakage causes the temperature to drop sharply. At this time, the concrete is in a low-temperature environment, and it is of great significance for the factory to maintain a high strength of the concrete in a low-temperature environment, which can avoid further expansion of the accident. Therefore, it is of forward-looking signi...
