Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, and specifically relates to a device for detecting the grout fullness of prefabricated structure steel bar sleeves. Background Technology

[0002] Currently, my country is vigorously promoting the development of green and environmentally friendly buildings. Prefabricated buildings perfectly embody this concept, featuring high construction efficiency, environmental friendliness, and excellent quality. Grouting connection with steel sleeves is a commonly used main connection node type in prefabricated building structures, and the construction quality of the sleeve grouting directly affects the structural performance of the building.

[0003] Existing equipment cannot detect the fullness of grout before initial setting. Once the grout has initially set, even if the test reveals that the grout is not dense, it is difficult to take remedial measures such as supplementary grouting. Moreover, the cost of remedial measures is high, which affects the connection performance of the sleeve grouting connection and creates potential quality hazards for prefabricated structures.

It also facilitates the removal of the L-shaped plate to compare the motion trajectory curve on the template with the standard motion trajectory curve, making it easier to replace the template.

[0015] The present invention is further configured such that a clamping rod is bolted to the rear side of the clamping plate, and a rubber pad is glued to the rear end of the clamping rod.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A device for detecting the fullness of grouting in prefabricated steel sleeves includes a workbench 1. Support columns 2 are welded to all four sides of the bottom of the workbench 1. A support plate 3 is welded to the rear side of the top of the workbench 1. A hydraulic cylinder 4 is bolted to the bottom of the horizontal surface of the support plate 3. A slider 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. A detection rod 6 is provided at the bottom of the slider 5. A connecting rod 7 is bolted to the left side of the slider 5. A contour pen 8 is provided at the left end of the connecting rod 7. A vertical plate 9 is bolted to the left side of the top of the workbench 1. An L-shaped plate 10 is provided at the top of the vertical plate 9. Contouring paper 11 is adhered to the right side of the vertical surface of the L-shaped plate 10. The left side of the contour pen 8 contacts the right side of the contour paper 11. This device can detect the fullness of the grouting material before initial setting, avoiding problems caused by insufficient fullness of the grouting material in subsequent operations and use.

[0032] refer to Figure 4 The bottom of the slider 5 is provided with a first threaded hole 13, and the upper end of the detection rod 6 is threaded into the inside of the first threaded hole 13. By setting the first threaded hole 13, the detection rod 6 can be installed and disassembled quickly, which improves the operating efficiency and facilitates the cleaning and replacement of the detection rod 6.

[0033] refer to Figure 3 and Figure 4 The left end of the connecting rod 7 is provided with a second threaded hole 14, and the internal thread of the second threaded hole 14 is connected to the contour rod 141. The left end of the contour rod 141 is bolted to the right end of the contour pen 8. By setting the second threaded hole 14 and the contour rod 141, it is easy to quickly install and remove the contour rod 141, and it is easy to clean the contour pen 8 and replace the contour rod 141.

[0034] refer to Figure 1 , Figure 3 and Figure 4 The top of the upright plate 9 is provided with a slot 15, and the bottom of the horizontal surface of the L-shaped plate 10 is bolted with a locking block 151. The bottom of the locking block 151 is engaged with the inside of the slot 15. The top of the left side of the upright plate 9 is bolted with a stop block 16. By setting the slot 15, the locking block 151 and the stop block 16, the L-shaped plate 10 can be placed and removed quickly, and the motion trajectory curve on the copy paper 11 can be compared with the standard motion trajectory curve, which is convenient for replacing the copy paper 11.

[0035] refer to Figure 1 The bottom of the support column 2 is glued with an anti-slip pad 19. By setting the anti-slip pad 19, the stability of the overall device can be improved, and the shaking of the device can be prevented from causing adverse effects on operation.

[0036] Brief description of the operation: Start hydraulic cylinder 4, which drives slider 5 downwards, causing detection rod 6 to move to the grouting port of the sleeve. Hydraulic cylinder 4 continues to move downwards, causing detection rod 6 to slowly enter the sleeve from the grouting port and contact the grouting material. During the downward movement of slider 5 and detection rod 6, the profiling pen 8 moves downwards synchronously with the cooperation of connecting rod 7 and profiling rod 141. During this downward movement, the profiling pen 8 will trace a motion trajectory on the profiling paper 11. The operator can compare this trajectory with a standard trajectory to determine the fullness of the grouting material. It should be noted that the operator should set a comparison standard in advance. For example, setting the smooth, continuous curve trajectory traced by the profiling pen 8 on the profiling paper 11 as the standard trajectory indicates good grouting fullness. If the contour paper 11 shows a local longitudinal fracture movement trajectory, the grouting material in that area is not full; if the contour paper 11 shows a frequent sawtooth-like undulating movement trajectory, the internal density of the grouting material in that area may be insufficient.

[0037] Example 2:

[0038] refer to Figure 1 A device for detecting the grout fullness of prefabricated steel bar sleeves is provided. The top of the workbench 1 is equipped with a clamping mechanism 12, which can clamp and fix sleeves of different specifications, thus improving the applicability of the device.

[0039] refer to Figure 2 The clamping mechanism 12 includes a first fixing block 1201. The bottom of the first fixing block 1201 is bolted to the rear side of the top of the workbench 1. A second fixing block 1202 is bolted to the front side of the top of the workbench 1. A fixing hole 1203 is opened through the front side of the second fixing block 1202.

A clamping plate 1206 is fixedly connected to the other end of the fixing rod 1204. By setting the first fixing block 1201, the second fixing block 1202, the fixing hole 1203, the fixing rod 1204, the knob 1205, and the clamping plate 1206, sleeves of different specifications can be clamped and fixed, which improves the applicability of the device and saves the cost of frequent device replacement.

[0040] refer to Figure 2 A clamping rod 17 is bolted to the rear side of the clamping plate 1206, and a rubber pad 18 is glued to the rear end of the clamping rod 17. By setting the clamping rod 17 and the rubber pad 18, the sleeve can be clamped more easily, making the clamping force more secure and preventing the sleeve from shaking randomly and affecting subsequent operations.

[0041] refer to Figure 2The surface of knob 1205 is provided with anti-slip texture. By providing anti-slip texture, the operator can avoid slipping when turning knob 1205, thus improving the reliability of operation.

[0042] Brief description of the usage process: Place the sleeve on the top of the workbench 1, with one side of the sleeve in contact with the first fixing block 1201.
