Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, and in particular to a prefabricated hoisting wall pre-reserved reinforcement positioning device. Background Technology

[0002] Prefabricated construction is a modern construction method that involves prefabricating building components (such as walls and floor slabs) in a factory and then transporting these components to the construction site for assembly. This method not only improves construction efficiency but also ensures building quality and reduces environmental impact. In the process of prefabricated construction, the accurate positioning of the pre-reserved reinforcing bars when hoisting the walls is a key step, as it directly relates to the structural safety and construction quality.

[0003] A prefabricated hoisting wall pre-reserved bar positioning device is usually designed to ensure that the steel bars (i.e., bars) on the prefabricated wall can be accurately inserted into the corresponding foundation or beam pre-reserved holes during hoisting and installation. This device can be designed in various forms, but its core objective is to provide a precise positioning function so as to complete the assembly work quickly and accurately.

[0004] The existing technical solutions have the following shortcomings: Since the acceptance rate of prefabricated wall installation quality must not be less than 90%, in the actual process of inserting the reinforcing bars, the reserved reinforcing bars are not corrected and checked, resulting in the misaligned reinforcing bars being unable to be smoothly connected with the prefabricated wall sleeves. This leads to the continuous adjustment of the reserved reinforcing bars during the hoisting process, which affects the hoisting time and seriously affects the construction period. Therefore, it is necessary to design a prefabricated wall reserved reinforcing bar positioning device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated hoisting wall pre-reserved reinforcement positioning device to solve the problem mentioned in the background art that the reinforcement cannot be smoothly inserted into the prefabricated wall sleeve due to the lack of reinforcement positioning structure.

[0025] Combination Figures 1-5 This utility model discloses a prefabricated hoisting wall pre-reserved reinforcement positioning device, comprising a U-shaped mounting frame 1, a movable seat 2 provided on one side of the U-shaped mounting frame 1, and adjusting seats 3 fixed on the upper surface of both the U-shaped mounting frame 1 and the upper surface of the movable seat 2. Each adjusting seat 3 has a locking block 4 on its outer surface, and a limiting cylinder 41 fixed on the side of the locking block 4 away from the adjusting seat 3. Each limiting cylinder 41 has a positioning cylinder 5 inside. U-shaped grooves 11 are provided on both sides of the inner wall of the U-shaped mounting frame 1, and both sides of the movable seat 2 are fixed... There is a rectangular threaded sleeve 21, which is slidably connected to the U-shaped groove 11. The two sides inside the U-shaped groove 11 are rotatably connected to the threaded rod 22, which is threadedly connected to the rectangular threaded sleeve 21. The two sets of threaded rods 22 are connected by a belt 23. One end of one set of threaded rods 22 is fixed with a cross-groove knob 221. The end of the adjusting seat 3 near the limiting cylinder 41 is provided with a T-shaped groove 31. The inner side of the locking block 4 is fixed with a T-shaped block 42, which is slidably connected to the T-shaped groove 31.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Combination Figures 1-6The upper surface of the locking block 4 and the T-shaped block 42, as well as the end away from the limiting cylinder 41, are all provided with threaded grooves 43. Bolts 7 are threaded into the inside of the threaded grooves 43, and the bolts 7 penetrate the inside of the adjusting seat 3. The size of the T-shaped block 42 is adapted to the size of the T-shaped groove 31. The outer surface of the adjusting seat 3 is in close contact with the inner wall of the locking block 4. The cross-section of the locking block 4 is U-shaped. A scale 32 is provided at the end of the adjusting seat 3 away from the limiting cylinder 41. The inside of the limiting cylinder 41 is provided with internal threads 411, and the outside of the positioning cylinder 5 is provided with external threads 411. Thread 52, external thread 52 and internal thread 411 are threaded together. Guide seat 51 is fixed on the upper surface of positioning cylinder 5. The guide seat 51 is set in an inverted trapezoidal shape when viewed from the side. Fixing plate 6 is fixed on both sides of U-shaped mounting frame 1. Fixing hole 61 is opened on both sides of the inside of fixing plate 6. A through hole 12 is provided at one end of U-shaped mounting frame 1. The through hole 12 is connected to the inside of U-shaped groove 11. Cross groove knob 221 is located inside through hole 12. Tile sealant is provided at one end of U-shaped mounting frame 1. Tile sealant is located at one end of through hole 12.

[0028] In this embodiment, before the installation of the prefabricated wall, the first step is to accurately select the number of locking blocks 4 according to the length specifications of the wall. Then, the T-shaped block 42 is smoothly slidably connected to the T-shaped groove 31. At the same time, the position of the locking block 4 on the outside of the adjusting seat 3 is finely adjusted with the help of the scale 32. Since there are no pre-drilled holes on the outside of the adjusting seat 3, a screwdriver is used to slowly and steadily rotate the bolt 7 so that the bolt 7 passes smoothly through the interior of the adjusting seat 3 and is tightly threaded into the threaded groove 43. In this way, the position of the locking block 4 is firmly locked, thereby achieving precise control of the position of the limiting cylinder 41. When dealing with prefabricated walls of different widths, the operator only needs to turn the cross groove knob 221. With the transmission action of the belt 23, the two sets of threaded rods 22 rotate synchronously. This operation will drive the moving seat 2 and the adjusting seat 3 above it to move towards the other set of adjusting seats 3, thus cleverly adapting to prefabricated walls of various thicknesses. After completing the above steps, the U-shaped block 42 is installed through the fixing hole 61. The stable and fixed installation frame 1 creates favorable conditions for subsequent reinforcement insertion. Before hoisting the prefabricated wall, rigorous positioning correction and verification of the positioning structure is a crucial step. This effectively avoids deviations between the prefabricated wall and the reserved reinforcement, greatly accelerates the hoisting process, and significantly improves the pass rate of prefabricated wall installation quality acceptance. It is worth mentioning that the positioning cylinder 5 can flexibly select a matching specification according to the diameter of the reinforcement. The tight threaded connection between the external thread 52 and the internal thread 411 makes the connection between the clamp 4 and the positioning cylinder 5 more stable and reliable. Combined with the precise guiding effect of the guide seat 51 on the reinforcement, the time required for reinforcement fixing can be further shortened, effectively improving construction efficiency.
