Description

Technical Field

[0001] This utility model relates to the field of precast wall panel technology, and in particular to a precast exterior wall panel injection port structure. Background Technology

[0002] Precast exterior wall panels are factory-produced exterior wall panels, typically made of concrete or other building materials. They are prefabricated, cured, and then transported to the construction site for installation. While the foundation concrete is usually already cured during factory production, in actual use, additional concrete needs to be poured inside the panel to improve the wall's load-bearing capacity and stability. This helps strengthen the overall structure of the panel, ensuring it can withstand external loads and environmental factors.

[0003] During the grouting process, the grouting pipe needs to be firmly fixed in the grouting hole of the precast exterior wall panel to ensure that the concrete can be poured evenly to the required position. If the grouting pipe is unstable or not firmly fixed, the concrete may leak, resulting in uneven grouting or voids, which will affect the overall strength and thermal insulation performance of the wall. With a stable fixing device, problems that occur during the grouting process can be reduced, construction time can be shortened, and construction efficiency can be improved. Utility Model Content

[0004] This utility model provides a precast exterior wall panel injection port structure, which solves the problems mentioned in the background art, such as unstable injection pipes or failure to be firmly fixed, which may lead to concrete leakage, uneven injection, or voids.

When the pipe opening 21 is inserted into the grouting hole 11 on the precast wall panel 1, the interference fit of the limiting ring 211, which has a diameter larger than that of the grouting hole 11, ensures that the pipe opening 21 is stably fixed in the grouting hole 11.

[0026] like Figure 3 and Figure 5As shown, the prying part 22 is fixedly connected to one end of the pipe opening 21. The upper end of the prying part 22 is fixedly connected to the rear top 221. A front hook 222 is provided on one side of the rear top 221. A groove 223 is formed between the rear top 221 and the front hook 222. Multiple impact plates 23 are fixedly connected to the end of the prying part 22 facing the pipe opening 21. The multiple impact plates 23 are arranged around the circumference of the prying part 22. Multiple protrusions 231 are provided on the side of the impact plates 23. Using tools such as a hammer, the multiple impact plates 23 arranged circumferentially around the pry bar 22 are struck in sequence. After the impact plates 23 are subjected to force, the pipe opening 21 will move backward and gradually enter the pipe opening 21. After the grouting work of the precast wall panel 1 is completed, the grouting mechanism 2 can be removed from the precast wall panel 1. A pry bar or other tool is inserted into the groove 223. The head of the pry bar is pressed against the front hook 222, and the end of the hook is pressed against the rear top 221. By rotating the pry bar, the pipe opening 21 can be pulled out from the grouting hole 11.

[0027] like Figure 3 and Figure 4 As shown, the clamping assembly 24 is located at the other end of the prying part 22. The clamping assembly 24 includes a connecting pipe 241, a main clamping arm 242, a secondary clamping arm 243, and a fixing bolt 244. The connecting pipe 241 is fixed to the prying part 22. A rotating shaft 2411 is fixedly connected to the upright plate of the connecting pipe 241. The main clamping arm 242 is rotatably connected to the rotating shaft 2411.

Both the main clamping arm 242 and the secondary clamping arm 243 are arc-shaped. A secondary side groove 2431 is provided through the side of the secondary clamping arm 243. A fixing bolt 244 is provided at the intersection gap of the main side groove 2422 of the main clamping arm 242 and the secondary side groove 2431 of the secondary clamping arm 243. The injection pipe 3 is inserted into the interior of the connecting pipe 241. Insert the injection pipe 3 of the external feeding device into the connecting pipe 241, so that the concrete flows through the injection pipe 3 and the connecting pipe 241 into the interior of the precast wall panel 1. Rotate the main clamping arm 242 and the auxiliary clamping arm 243 to clamp the injection pipe 3. Then, insert the fixing bolt 244 into the cross gap between the main side groove 2422 of the main clamping arm 242 and the auxiliary side groove 2431 of the auxiliary clamping arm 243.

Multiple impact plates 23 arranged circumferentially around the prying part 22 are struck sequentially using a hammer or similar tool. Under pressure, the impact plates 23 cause the pipe opening 21 to move backward and gradually enter the grouting hole 11. After the limiting ring 211, whose diameter is larger than that of the grouting hole 11, enters the grouting hole 11, the interference fit ensures that the pipe opening 21 is stably fixed in the grouting hole 11. The injection pipe 3 of the external feeding device is inserted into the connecting pipe 241. Rotating the main clamping arm 242 and the auxiliary clamping arm 243 clamps the injection pipe 3. Then, in the main side groove 2 of the main clamping arm 242... Insert a fixing bolt 244 into the intersecting gap of the secondary side groove 2431 of the secondary clamping arm 242 and the secondary clamping arm 243. Tighten the fixing bolt 244 to fix the main clamping arm 242 and the secondary clamping arm 243, so that the grouting pipe 3 is firmly fixed. Pour concrete into the grouting pipe 3, so that the concrete flows through the grouting pipe 3 and the connecting pipe 241 into the interior of the precast wall panel 1. After the grouting work of the precast wall panel 1 is completed, the grouting mechanism 2 can be removed from the precast wall panel 1. Use a pry bar or other tools to insert into the groove 223. The head of the pry bar is pressed against the front hook 222, and the end of the hook is pressed against the rear top 221. Rotate the pry bar to pull the pipe 21 out of the grouting hole 11.
