Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a concrete air tightness detection device. Background Art

[0002] In the field of concrete quality control, air tightness testing plays a vital role. The air tightness of concrete is directly related to the durability, impermeability and long-term stability of its structure. Therefore, accurately evaluating the air tightness of concrete is crucial to ensuring the quality of construction.

[0003] At present, concrete air tightness testing mainly relies on a series of specialized testing equipment, such as air tightness testing barrels, pressure gauges, etc. These devices evaluate the air tightness of concrete by applying a certain pressure and then recording the pressure value and the rate at which gas passes through the test piece. However, when testing concrete air tightness, small pores of air often remain inside the concrete test piece inside the container tank. The presence of these small pores of air will have a significant impact on the test results, resulting in a low measured gas permeation rate, thereby underestimating the actual air tightness of the concrete. Secondly, as the test process progresses, these small pores of air may gradually release, resulting in pressure fluctuations and instability, further affecting the accuracy of the test results.

[0004] Since the concrete air tightness test is usually carried out by simply pouring the concrete into the test bucket and stirring and smoothing it, it is difficult to ensure that all bubbles and pores are completely removed during the pouring and smoothing process. These residual bubbles and pores will affect the rate of gas permeation through the concrete during the subsequent test process, resulting in inaccurate test results. Therefore, there is an urgent need for a concrete air tightness test device with a shaking function to remove small pore air. Utility Model Content

[0006] The technical solution of the utility model: In order to solve the above-mentioned technical problems, the utility model provides a concrete air tightness detection equipment, including a base, a mounting frame, a connecting shaft, a detection barrel and a shaking mechanism, the mounting frame is symmetrically installed on the base, the connecting shaft is slidably installed on the mounting frame, the two connecting shafts are commonly connected to the detection barrel, and the shaking mechanism for vibrating the detection barrel to remove air from small holes is arranged on the base.

[0007] Preferably, the shaking mechanism includes: a limit ring, a fixed frame, a cam and a motor. The limit ring is installed on the base, and a motor is installed on one side of the base. The motor is connected to the fixed frame through an output shaft. At least one cam is arranged on the fixed frame, and the cam is in intermittent contact with the detection barrel.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1: A concrete air tightness detection device, such as Figure 1-Figure 3 As shown, it includes a base 1, a mounting frame 2, a connecting shaft 3, a detection barrel 4 and a shaking mechanism. The base 1 is provided with mounting frames 2 on both sides. A slide groove is opened on the upper part of the mounting frame 2, and a connecting shaft 3 is slidably arranged in the slide groove. The two connecting shafts 3 are jointly installed with the detection barrel 4, which is the main equipment for detecting the air tightness of concrete. The shaking mechanism is installed in the middle of the base 1. The shaking mechanism can make the detection barrel 4 vibrate continuously, so as to remove the small pore air inside the concrete. The shaking mechanism includes: a limit ring 5, a fixing frame 6, a cam 7 and a motor 8. The base 1 is a two-layer structure. The limit ring 5 is installed on the upper layer of the base 1. The detection barrel 4 is placed on the limit ring 5 in a normal state. The motor 8 is installed on the right side of the lower layer of the base 1. The left side of the motor 8 is connected to the fixing frame 6 through the output shaft. Three cams 7 are installed on the fixing frame 6. The rotation of the cam 7 can lift the detection barrel 4.

[0023] When pouring concrete for mixing and leveling, start the motor 8, which drives the fixing frame 6 to rotate through the output shaft, thereby rotating the cam 7 thereon. When the raised part of the cam 7 rotates to the vertical direction, that is, the connecting shafts 3 on both sides of the detection barrel 4 slide and lift up along the mounting frame 2, the raised part of the cam 7 rotates to the horizontal direction, and the connecting shafts 3 on both sides of the detection barrel 4 slide and fall along the mounting frame 2. As the cam 7 continues to rotate, the detection barrel 4 is intermittently lifted up, achieving the effect of continuous shaking of the detection barrel 4, causing the bubbles originally existing in the concrete to be impacted and squeezed, so that the bubbles will burst and disappear.

[0024] Embodiment 2: Based on embodiment 1, Figure 4 As shown, it also includes a fixing mechanism, which can fix the detection barrel 4 at a certain height, so as to facilitate the tipping of the detection barrel 4. The fixing mechanism includes a mounting block 9, an insertion rod 10 and a magnet 11. A mounting block 9 is arranged on the upper right side of the mounting frame 2, and an insertion rod 10 is slidably arranged on the mounting block 9. A magnet 11 is installed in the middle of the insertion rod 10. Since the mounting frame 2 is made of iron material, the magnet 11 will be adsorbed and fixed when it moves to the vicinity of the mounting frame 2.

[0025] like Figure 2 As shown, it also includes: universal wheels 12, pull rods 13 and handles 14. Universal wheels 12 are set at the four corners of the bottom of the base 1. The universal wheels 12 are convenient for easily moving and adjusting the position of the device. Pull rods 13 are installed on both sides of the base 1. The pull rods 13 are convenient for easily lifting and moving the device. This method is more labor-saving than direct transportation. A handle 14 is installed on the front side of the detection barrel 4. The handle 14 is convenient for tilting the detection barrel 4.

[0026] When the concrete in the detection bucket 4 needs to be poured out, the detection bucket 4 is first lifted up so that the connecting shafts 3 on both sides slide to the upper part of the mounting frame 2, and then the insertion rods 10 on both sides are pushed, and then the magnets 11 on the insertion rods 10 are adsorbed with the mounting frame 2, so that the insertion rods 10 are stably inserted into the mounting frame 2, thereby preventing the connecting shaft 3 from sliding down along the mounting frame 2, and then the detection bucket 4 is rotated by the handle 14 to tilt the detection bucket 4 so that the internal concrete is poured out. The tilt angle of the detection bucket 4 can be conveniently controlled, so that the internal concrete is poured out more easily, which is more labor-saving and accurate than directly lifting the detection bucket 4.

[0027] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
