Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated concrete structure testing device, and in particular to a prefabricated concrete structure testing device. Background Technology
[0002] Prefabricated concrete buildings refer to concrete structures designed and constructed primarily using precast reinforced concrete components produced in factories, assembled on-site. They are generally divided into two main categories: fully prefabricated buildings and partially prefabricated buildings. Fully prefabricated buildings are typically low-rise or multi-story buildings with lower seismic fortification requirements; partially prefabricated buildings generally use precast components for their main structural members.
[0003] Chinese Patent No. CN222560914U discloses a bridge concrete structure testing device, including an upper plate and a lower plate. A first connecting plate is fixedly installed on the lower surface of the upper plate, and a second connecting plate is fixedly installed on the upper surface of the lower plate. Thickness detection mechanisms are provided on the upper and lower plates. The device can use a laser rangefinder on the upper plate and a laser receiver on the lower plate to cooperate in order to detect the thickness of the plate-shaped bridge concrete structure. The detection mechanism can move on the bridge concrete structure to detect the thickness at different locations, making the detection more comprehensive.
[0004] However, the above technical solution has the following shortcomings: when detecting the thickness of the concrete structure, the detection device cannot quickly detect the surface flatness of the concrete. Although the allowable error for prefabricated concrete is relatively large, if the two connected concrete components tilt due to insufficient surface flatness, it will easily lead to poor building quality.

[0018] Example 1
[0019] like Figures 1-3 As shown in this embodiment, a prefabricated concrete structure testing device includes a frame 1, a drive assembly, and a testing assembly 4. A control panel 2 is mounted on the frame 1, and a tie rod 3 is rotatably connected to the frame 1. The drive assembly is mounted on the frame 1, and a mounting rod 8 is mounted at its output end. A rotating disk 9 is detachably mounted on the mounting rod 8, and multiple positioning components are arranged in a ring around the rotating disk 9. The testing assembly 4 is hinged to each of the multiple positioning components, and a bottom wheel 5 is slidably mounted on each of the multiple testing components 4. The testing assembly 4 includes a fixing frame 41 hinged to the positioning components and a detachable mounting rod 3. The device includes a mounting frame 43 placed on a fixed frame 41, multiple lifting components detachably arranged side-by-side on the mounting frame 43, multiple laser receiving plates 44 arranged on the mounting frame 43, and a laser emitter 410 arranged on each of the multiple lifting components; the multiple laser emitters 410 and the multiple laser receiving plates 44 are distributed one-to-one; the mounting frame 43 is equipped with a handle 6; when the device is used to inspect the side of a concrete component, the user can remove the mounting frame 43 from the fixed frame 41, hold the handle 6 to fit against the wall for inspection; the fixed frame 41 and the mounting frame 43 can be connected by an extension cord.
[0020] In this embodiment, the detection device is placed at the point to be detected, the rotating fixed frame 41 is fixed by the positioning component, the driving component drives the rotating disk 9 to rotate, the rotating disk 9 drives the fixed frame 41 to rotate, the fixed frame 41 drives the mounting frame 43 to move, and the mounting frame 43 drives multiple lifting components to move on the surface of the concrete component, so that the lifting components rise and fall according to the state of the concrete component surface, thereby driving the laser emitter 410 to adjust its position, so that the laser receiving plate 44 receives the signal from the laser emitter 410. The signals received by the multiple laser receiving plates 44 are displayed on the control panel 2, improving the practicality of the detection device.
[0021] Example 2
[0022] like Figure 2 As shown, the prefabricated concrete structure testing device proposed in this embodiment, compared with the first embodiment, includes a testing frame 45 mounted on the mounting frame 43, a lifting rod 46 slidably mounted on the testing frame 45, a ball bearing 47 rotatably mounted on the lifting rod 46, an intermediate ring 48 mounted on the lifting rod 46, and a spring 49 at each of the upper and lower ends of the intermediate ring 48.
[0023] In this embodiment, the ball bearing 47 rolls in contact with the ground, and the ground drives the lifting rod 46 to rise and fall through the ball bearing 47. At the same time, two springs 49 from the upper and lower ends of the middle ring 48 respectively allow the lifting rod 46 to automatically reset after rising and falling, reducing manual adjustment by the user and reducing the workload of workers.
[0024] Example 3
[0025] like Figure 3 As shown, the prefabricated concrete structure testing device proposed in this embodiment, compared with the first embodiment, the positioning component in this embodiment includes a positioning plate 10 set on the rotating disk 9, a limiting rod 11 set on the positioning plate 10, and an elliptical block rotatably set on the height of the limiting rod 11; the fixing frame 41 is hinged to the positioning plate 10.
[0026] In this embodiment, after the fixing frame 41 is attached to the positioning plate 10, the elliptical block is rotated so that the major axis of the elliptical block is connected to the fixing frame 41, thereby restricting the fixing frame 41 from moving freely and improving the detection accuracy of the device.
[0027] Example 4
[0028] like Figures 1-3 As shown in the figure, the prefabricated concrete structure testing device proposed in this embodiment, compared with the first embodiment, has a limiting block 7 on the frame 1 and an abutment block 42 on the fixing frame 41. The limiting block 7 abuts against the abutment block 42. Both the limiting block 7 and the fixing frame 41 are made of plastic. The plastic material of the limiting block 7 and the fixing frame 41 can be deformed to a certain extent, so that the limiting block 7 and the fixing frame 41 can be detached from the abutment by bending, thereby improving the fixing effect of the testing component.
[0029] An extension ring 12 is provided on the frame 1, and a slip ring is provided on the extension ring 12. A carbon brush 13 is provided on the rotating disk 9. The carbon brush 13 slides in contact with the slip ring, so that current and signal flow from the frame 1 to the rotating disk 9 through the carbon brush and the slip ring. The rotating disk 9 transmits signals and current by abutting against the fixed frame 41, and the fixed frame 41 transmits signals and current by abutting against the mounting frame 43, thereby ensuring the detection effect of the device. A grounding component 14 is provided at the bottom of the rotating disk 9. The grounding component 14 can be set as a caster wheel or an intermediate bearing. If it is a caster wheel, the user can place the device on the ground and pull it, reducing the difficulty of transporting the device. If it is an intermediate bearing, one end of the intermediate bearing contacts the ground, improving the smoothness of the rotation of the rotating disk 9.
