Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete structure detection device for construction engineering quality supervision. Background Art

[0002] With the acceleration of urbanization, the number and scale of construction projects are constantly expanding. As a widely used material in construction projects, the quality of concrete is directly related to the overall safety and stability of the building. It is particularly important to supervise and test the quality of concrete structures to ensure that the quality of concrete meets the design requirements. In the process of concrete testing, it is necessary to drill core samples of the formed concrete and observe or test the samples.

[0003] A construction project quality supervision concrete structure detection device disclosed in Chinese patent CN201921632447.5, the construction project quality supervision concrete structure detection device is provided with a wall plate that is arranged to be a left-right movable device through a telescopic rod. While ensuring that the wall plate is in contact with the concrete test surface, the operator can better keep the axis of the concrete rebound tester perpendicular to the concrete test surface during the operation of the concrete rebound tester. However, the construction project quality supervision concrete structure detection device will generate a large amount of dust during drilling, which will escape into the air from the gap between the wall plate and the sampling tube, affecting the air quality. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a concrete structure detection device for monitoring the quality of construction projects, which effectively solves the shortcomings of the prior art.

[0005] The purpose of the utility model is achieved through the following technical solutions: a construction project quality supervision concrete structure detection device, including a concrete sampling body, the bottom of the concrete sampling body is fixedly connected to a motor, the output end of the motor is fixedly connected to a sampling tube, the bottom of the concrete sampling body is fixedly connected to a fixing plate, the four corners of the bottom of the fixing plate are fixedly connected to telescopic rods, the output end of the telescopic rod is fixedly connected to a support plate, the middle of the support plate is fixedly connected to a dust hood, and one side of the dust hood is fixedly connected to a dust suction fan.

[0006] Optionally, the dust hood is hemispherical, a circular hole is provided in the middle of the dust hood, the diameter of the circular hole in the middle of the dust hood is matched with the diameter of the sampling tube, and the dust suction port of the dust suction fan is located inside the dust hood.

[0007] The above technical solution is adopted: by setting a dust collecting hood with a dust suction fan in the middle of the support plate, the dust generated by drilling during the sampling process is adsorbed and collected, thereby reducing the dust generated by the device during the concrete sampling and testing process and optimizing the air quality of the testing site.

[0008] Optionally, compression springs are sleeved on the outer sides of the telescopic rods, and the elastic force of the compression springs is greater than the total gravity of the concrete sampling body.

[0009] The above technical solution is adopted: by setting a telescopic rod with a compression spring between the fixed plate and the support plate, the descending direction of the sampling tube is restricted, so that the sampling tube can remain stable during the drilling sampling process, making the drilling sampling more labor-saving, and the concrete sampling body can automatically reset and rise after the drilling sampling is completed to take out the concrete sample, and the structural strength of the concrete can be judged according to the sampled concrete sample.

[0010] Optionally, the telescopic stroke of the telescopic rod is matched with the compression stroke of the compression spring, and the length of the sampling tube is greater than the telescopic stroke of the telescopic rod.

[0011] The above technical solution is adopted: by limiting the telescopic stroke of the telescopic rod and the length of the sampling tube, the sampling tube can continue to descend during the contraction process of the telescopic rod to drill and sample the concrete.

[0012] Optionally, handles are fixedly connected to both sides of the concrete sampling body, and anti-slip grooves are provided on the surfaces of the handles.

[0013] Optionally, both sides of the support plate are rotatably connected to side plates, and the middle parts of the rotating shafts of the side plates are sleeved with torsion springs, and the torsion of the torsion springs makes the side plates and the support plate perpendicular to each other.

[0014] The above technical solution is adopted: by arranging side plates on both sides of the support plate, the support plate is kept in a vertical state under the torsion of the torsion spring, and will not take up a large space during normal storage. When using the device for concrete sampling and testing, the side plate can be rotated to a horizontal state, and heavy objects such as sand and gravel can be placed on the side plate to counterweight the support plate and improve the stability of the support plate.

[0015] The utility model has the following advantages:

[0016] 1. The construction project quality supervision concrete structure detection device sets a dust collection hood with a dust suction fan in the middle of the support plate to absorb and collect the dust generated by drilling during the sampling process, thereby reducing the dust generated by the device during the concrete sampling and detection process and optimizing the air quality of the detection site.

[0017] 2. The device for detecting concrete structures for monitoring the quality of construction projects sets a telescopic rod with a compression spring between a fixed plate and a supporting plate to limit the descending direction of the sampling tube, so that the sampling tube can remain stable during the drilling sampling process, making the drilling sampling more labor-saving, and the concrete sampling body can automatically reset and rise to take out the concrete sample after the drilling sampling is completed, and the structural strength of the concrete can be judged based on the sampled concrete sample. By limiting the telescopic stroke of the telescopic rod and the length of the sampling tube, the sampling tube can continue to descend during the contraction of the telescopic rod to perform drilling sampling on the concrete.

[0018] 3. The construction engineering quality supervision concrete structure detection device sets side plates on both sides of the support plate. The support plate is kept in a vertical state under the torsion of the torsion spring, and does not take up a large space during normal storage.

By arranging the dust hood 7 with the dust suction fan 8 in the middle of the support plate 6, the dust generated by drilling during the sampling process is adsorbed and collected, thereby reducing the dust generated by the device during the concrete sampling and testing process, and optimizing the air quality of the testing site.

[0028] Embodiment 2: Compression springs 9 are sleeved on the outer sides of the telescopic rods 5. The elastic force of the compression springs 9 is greater than the total gravity of the concrete sampling body 1. By arranging the telescopic rods 5 with compression springs 9 between the fixed plate 4 and the support plate 6, the descending direction of the sampling tube 3 is restricted, so that the sampling tube 3 can remain stable during the drilling sampling process, making the drilling sampling more labor-saving.
