Description

Technical Field

[0001] The utility model relates to the technical field of airport construction, and particularly relates to a device for quickly measuring the thickness of airport pavement slabs. Background Art

[0002] During the construction of airport pavement concrete, the pavement elevation is mainly controlled by measuring the elevation of the water-stable layer. After the water-stable construction is completed, a grid measurement is carried out on the water-stable layer. During the measurement process, the elevation of the points involved in the grid corners usually has a small error. However, during the large-area water-stable construction, the measurement and control are generally carried out according to the design elevation provided by the grid corners. This will result in the areas between the corners being controlled along the elevations on both sides. More or less, due to the large range of the grid, there will be elevation deviations in the middle area. After the pavement formwork is set up, the thickness of the middle concrete slab is usually measured by pulling lines on both sides of the adjusted formwork. When it is found that the thickness of the pavement slab is insufficient, it needs to be processed in advance. However, this method takes a lot of time to completely eliminate the problem of insufficient slab thickness and the effect is not very ideal, resulting in the problem of insufficient slab thickness during the core sampling process in the later acceptance, affecting the completion acceptance. Therefore, it is necessary to design a device for quickly measuring the thickness of airport pavement slabs. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a device for quickly measuring the thickness of airport pavement slabs, which has the advantages of simple and compact structure, easy turnover, can quickly measure the slab thickness, and ensure the construction quality.

[0004] The technical solution of the utility model is realized as follows:

[0005] A device for quickly measuring the thickness of airport pavement slabs includes an upper bracket, a lower bracket, warning lights, movable rod bodies, universal wheels and rollers. The upper bracket is installed directly above the lower bracket. The warning lights are evenly installed on the upper bracket, and the switch of the warning lights is located on the lower surface of the upper bracket. The movable rod bodies pass through the lower bracket, and the movable rod bodies are arranged in one-to-one correspondence with the warning lights, and the top ends of the movable rod bodies are directly below the switches of the warning lights. The universal wheels are installed at the bottom ends of the movable rod bodies, and the rollers are arranged on both sides of the lower surface of the lower bracket.

[0006] Furthermore, the lower bracket is provided with mounting holes for the movable rod bodies to penetrate, and the movable rod bodies are slidably arranged in the mounting holes.

[0007] Furthermore, pipe clamps are arranged on the outer part of the movable rod bodies, and the pipe clamps are located above the lower bracket.

[0008] Furthermore, the movable rod bodies include upper rod bodies and lower rod bodies. The top ends of the lower rod bodies are threadedly sleeved on the bottom ends of the upper rod bodies, and the universal wheels are installed at the bottoms of the lower rod bodies.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] As Figure 1 shown, this embodiment provides a device for quickly measuring the thickness of the airport pavement slab, including an upper bracket 1, a lower bracket 2, a warning light 3, a movable rod body 4, a universal wheel 5 and a roller 6. The upper bracket 1 is installed directly above the lower bracket 2. The warning lights 3 are evenly installed on the upper bracket 1, and the switch of the warning light 3 is located on the lower surface of the upper bracket 1. The movable rod body 4 is penetrated through the lower bracket 2. The movable rod body 4 is arranged in one-to-one correspondence with the warning light 3, and the top end of the movable rod body 4 is directly below the switch of the warning light 3. The universal wheel 5 is installed at the bottom end of the movable rod body 4, and the rollers 6 are arranged on both sides of the lower surface of the lower bracket 2.

[0017] When applying this rapid measuring device for the thickness of airport pavement slabs, directly slide the device rapidly in the formwork that has been set up. When the pavement thickness does not meet the requirements, the movable rod body 4 will move upward to touch the switch of the warning light 3. By observing the change of the warning light 3, the area where the pavement slab thickness is insufficient can be judged, so as to ensure the thickness of the pavement before pavement construction and guarantee the construction quality.

[0018] The lower bracket 2 is provided with an installation hole for the movable rod body 4 to penetrate through, and the movable rod body 4 is slidably arranged in the installation hole. A pipe clamp 7 is arranged outside the movable rod body 4, and the pipe clamp 7 is located above the lower bracket 2. The pipe clamp 7 can prevent the whole movable rod body 4 from disengaging from the installation hole, thereby playing a role in installing the movable rod body 4 on the lower bracket 2. At the same time, the pipe clamp 7 does not affect the up and down displacement of the movable rod body 4. In addition, by adjusting the position of the pipe clamp 7 on the movable rod body 4, the thickness of the pavement slab is controlled.

[0019] The movable rod body 4 includes an upper rod body 4.1 and a lower rod body 4.2. The top end of the lower rod body 4.2 is threadedly sleeved on the bottom end of the upper rod body 4.1. The universal wheel 5 is installed at the bottom of the lower rod body 4.2. By rotating the upper rod body 4.1 or the lower rod body 4.2, the overall length of the movable rod body 4 can be adjusted, and then the distance between the top of the upper rod body 4.1 and the switch of the warning light 3 can be controlled, so as to be better applied to the operation of rapidly measuring the thickness of airport pavement slabs.

[0020] The roller 6 has an axial structure, and a row of rollers 6 are equidistantly distributed at both ends of the lower surface of the lower bracket 2. During the application of this rapid measuring device for the thickness of airport pavement slabs, the roller 6 directly moves on the pavement formwork.

[0021] Long screw rods 8 are fixedly installed on both sides of the lower bracket 2. The top ends of the long screw rods 8 are connected with two nuts 9, and the two nuts 9 are respectively located on the upper and lower sides of the upper bracket 1. By adjusting the nuts 9, the distance between the upper bracket 1 and the lower bracket 2 can be adjusted. In the measurement of different slab thicknesses, the height of the upper bracket 1 can be adjusted to measure different slab thicknesses.

[0022] Specifically, before pavement construction, place this device on the pavement formwork and measure by sliding the device. When the local water-stable layer is too high, the movable rod body 4 will move upward and touch the switch at the bottom of the warning light 3 on the upper bracket 1, and the warning light 3 will give an early warning. When the warning light 3 at a certain place lights up, it indicates that the local area of the water-stable layer is higher, and it can be processed in advance on site, thus ensuring the thickness of the pavement slab.

[0023] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
