Description

Technical Field

[0001] This utility model relates to the field of building hanger technology, and in particular to a building hanger for prefabricated buildings. Background Technology

[0002] In prefabricated construction, building scaffolding (or hoisting equipment) is an indispensable key component. Its existence and application are mainly based on the following reasons: The core of prefabricated construction lies in the factory production and on-site assembly of prefabricated components (prefabricated wall panels, prefabricated floor slabs, etc.). Therefore, the design and selection of scaffolding directly affect the safety and efficiency of hoisting operations. During the construction of prefabricated buildings, hoisting operations involve high risks, such as scaffolding breakage, component swaying, and falls from heights. Therefore, pre-hoisting inspections are also an important safety measure.

[0003] In existing technologies, traditional hoisting methods typically use fixed hangers or simple hooks, which make it difficult to flexibly adjust the position of the hoisting points according to the size, weight and quantity of prefabricated components. This can lead to components tilting, swaying or even one end lifting up during hoisting, affecting construction and safety. Therefore, we propose a building hanger for prefabricated buildings to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a building hanger for prefabricated buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prefabricated building scaffold includes a U-shaped frame. Two recessed frames are slidably connected inside the U-shaped frame. Each recessed frame has a telescopic rod rotatably connected to its top. A common I-shaped shaft rotatably connects the two telescopic rods. Connecting rods are rotatably connected to the outer walls of both telescopic rods, with one end of each connecting rod rotatably connected to the inner wall of the U-shaped frame. Two guide rods are fixedly connected to the outer walls of both recessed frames. Four slots are formed on the outer wall of the U-shaped frame. A mating plate is fixedly connected to one end of each recessed frame. Two sliding grooves are formed on the outer walls of each mating plate. U-shaped legs are slidably connected to the inner walls of the four sliding grooves. Multiple through holes are evenly formed on the outer walls of the four U-shaped legs. Two insertion holes are formed on each of the two mating plates. Pins are slidably connected to the inner walls of the four insertion holes. A limiting component is provided on the outer wall of the U-shaped frame.

[0007] Preferably, the limiting component includes four connecting plates, one end of each of the four connecting plates is fixedly connected to the outer wall of the U-shaped frame, the outer wall of each of the four connecting plates is provided with threaded holes, and the inner wall of each of the four threaded holes is threaded with a threaded pressing rod, thereby limiting the top of the precast component by setting the limiting component.

[0008] Preferably, a lifting ring is fixedly connected to the top of the I-shaped shaft, and the lifting ring is connected to the hook on the existing lifting equipment.

[0009] Preferably, the outer wall of the guide rod is slidably connected to the inner wall of the strip groove, the return frame moves linearly through the guide rod and the strip groove, and the return frame moves along the inside of the U-shaped frame, with the contact surface coated with lubricating oil.

[0010] Preferably, one end of each of the four pins is slidably connected to the inner wall of the four through holes, thereby fixing the position of the U-shaped bracket by setting the pins.

[0011] Preferably, two reinforcing rods are fixedly connected between the two U-shaped legs to increase the connection strength between the two U-shaped legs.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution, through adjustable U-shaped legs and threaded pressure rods, can flexibly adapt to prefabricated components of different thicknesses and quantities, ensuring that the components are stably attached to the U-shaped frame during hoisting and avoiding tilting or lifting. At the same time, the linkage structure of telescopic rods and connecting rods enables the U-shaped frame to automatically tighten inward, achieving reliable clamping of prefabricated components, improving the safety and efficiency of hoisting, and reducing the difficulty of manual adjustment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a building hanger for prefabricated buildings is disclosed, including a U-shaped frame 1. The U-shaped frame 1 serves as the main support structure of the hanger, providing overall rigidity and stability. Two spiral frames 2 are slidably connected inside the U-shaped frame 1. The two spiral frames 2 are symmetrically slidably connected inside the U-shaped frame 1 and can move horizontally along the inner wall of the U-shaped frame 1. The sliding design of the spiral frames 2 enables them to adaptively adjust the clamping width, making them suitable for prefabricated components of different sizes.

[0021] Both tops of the two U-shaped frames 2 are rotatably connected to telescopic rods 3, and the same I-shaped shaft 4 is rotatably connected between the two telescopic rods 3. The I-shaped shaft 4 is fixedly connected between the two telescopic rods 3, and its top is fixedly connected to a lifting ring 5. As the core force transmission component for hoisting, the top of the I-shaped shaft 4 is fixedly connected to a lifting ring 5, which is used to connect with the hook of external hoisting equipment to realize the lifting control of the frame. The outer walls of the two telescopic rods 3 are rotatably connected to connecting rods 6 through existing shafts. One end of each connecting rod 6 is rotatably connected to the inner wall of the U-shaped frame 1 through existing shafts. The two telescopic rods 3 are respectively rotatably connected to the top of the U-shaped frame 2 and connected to each other through the I-shaped shaft 4 to form a linkage mechanism. The telescopic rods 3 are simultaneously rotatably connected to the connecting rods 6 to realize the synchronous movement of the U-shaped frame 2.

[0022] Two guide rods 7 are fixedly connected to the outer walls of both U-shaped frames 2. Four slots 8 are formed on the outer wall of the U-shaped frame 1. The outer walls of the guide rods 7 are slidably connected to the inner walls of the slots 8. The cooperation between the guide rods 7 and the slots 8 ensures that the U-shaped frame 2 can only move linearly along a predetermined trajectory, avoiding deviation or jamming and improving the reliability of hoisting. A docking plate 9 is fixedly connected to one end of each of the two U-shaped frames 2. Two sliding grooves are formed on the outer walls of both docking plates 9. U-shaped legs 10 are slidably connected to the inner walls of the four sliding grooves. The U-shaped legs 10 can be adjusted up and down to prevent… During hoisting, the components tilt or warp, and the reinforcing rods 13 enhance their structural strength and improve their load-bearing capacity. The outer walls of the four U-shaped legs 10 are evenly provided with multiple through holes 11, and each of the two connecting plates 9 has two insertion holes. The inner walls of the four insertion holes are slidably connected with pins 12, and one end of each of the four pins 12 is slidably connected to the inner wall of the four through holes 11. Two reinforcing rods 13 are fixedly connected between the two U-shaped legs 10. The reinforcing rods 13 prevent the U-shaped legs 10 from deforming when hoisting heavy components, thereby improving the stability and service life of the hoist.

[0023] The outer wall of the U-shaped frame 1 is provided with a limiting component, which includes four connecting plates 14. One end of each of the four connecting plates 14 is fixedly connected to the outer wall of the U-shaped frame 1. Each of the four connecting plates 14 has a threaded hole on its outer wall, and each of the four threaded holes has a threaded pressure rod 15 threadedly connected to its inner wall.

[0024] Working principle: When hoisting precast components (precast wall panels, precast floor slabs, etc.), the hooks on the existing hoisting equipment are connected to the lifting rings 5. The hoisting equipment then raises and lowers the lifting rings 5. Depending on the number of precast components to be hoisted at one time, the thickness of the precast components, and the overall weight, one or more components can be hoisted to avoid overloading. The four pins 12 can be slid out from the four through holes 11 and the four insertion holes to release the position fixation of the four U-shaped legs 10. The position fixation of the four U-shaped legs 10 can be moved up and down through the four sliding grooves on the two docking plates 9. The vertical position of the U-shaped legs 10 on the U-shaped frame 1 is adjusted so that the top of the precast component can be as close as possible to the bottom of the U-shaped frame 1 during hoisting, and it can rotate. Four threaded pressure rods 15, in conjunction with the hoisting of four U-shaped legs 10, press the bottom of the four threaded pressure rods 15 against the top of the precast component, limiting its movement and preventing one end of the precast component from tilting up during hoisting. At the same time, the U-shaped frame 1 descends so that the bottom of the U-shaped legs 10 is located at the bottom of the precast component. As the hoisting equipment lifts, the two telescopic rods 3 move inward by tilting and their own weight. With the traction of the two connecting rods 6, the two return frames 2 move inward along the inside of the U-shaped frame 1, and the guide rod 7 moves inward in a straight line along the strip groove 8. The inward movement of the two return frames 2 drives the two docking plates 9 to move inward. At this time, the four U-shaped legs 10 move inward in pairs to hoist the precast component.
