Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically, to a pre-assembled structure for building construction. Background Art

[0002] During the process of building construction, traditional on-site construction requires a large amount of manpower, material resources and a lot of time, and there are also problems such as low efficiency and difficulty in guaranteeing construction quality. To solve these problems, a pre-assembled structure for building construction has emerged. The building to be constructed is divided into various prefabricated components for reservation. After different types of prefabricated components are separately processed and produced, they are then uniformly transported to the construction site for assembly. Compared with traditional on-site construction, it can effectively save manpower and material resources and improve the construction efficiency.

It includes a plurality of prefabricated components and also includes a plurality of transportation and bearing devices. The transportation and bearing device includes a bearing frame. A pressing plate is slidably arranged inside the bearing frame in the vertical direction. The bottom of the pressing plate is used to abut against the top of the prefabricated component. An abutting plate is slidably arranged at the bottom of the pressing plate. A first elastic member is arranged between the abutting plate and the pressing plate. A limiting member is arranged on the bearing frame. The limiting member is used to limit the position of the pressing plate on the bearing frame. This application can effectively fix the prefabricated component during transportation.

[0004] However, it is found that the following problems exist in the implementation of the related technology: In the above, according to the overall length of the prefabricated component, a suitable number of bearing frames are selected. Then the prefabricated component is passed through the bearing frame and placed on the inner wall of the bearing frame. After the placement of the prefabricated component is completed, the prefabricated component is fixed, and thus the prefabricated component can be fixed during transportation. However, when the prefabricated component is transported to the destination, the prefabricated component needs to be removed from the bearing frame. The removal process requires the prefabricated component to be separated from the bearing frame, so it is necessary to manually lift the prefabricated component and remove all the bearing frames before the prefabricated component can be removed, which will make the entire removal process time-consuming and laborious and very inconvenient.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the present utility model provides a technical solution: a pre-assembly structure for building construction, including a bearing frame 2, a vertical fixing mechanism 3 is arranged on the inner side wall of the bearing frame 2, a horizontal fixing mechanism 4 is arranged on the inner bottom of the bearing frame 2, brackets 5 are respectively fixedly connected to the two bottom sides of the bearing frame 2, a bidirectional lead screw 6 is respectively rotatably connected in the two brackets 5, two moving blocks 7 are respectively threadedly connected to the two bidirectional lead screws 6, guiding mechanisms are respectively arranged between the lower ends of the two moving blocks 7 and the inner bottom of the brackets 5, the upper ends of the two moving blocks 7 are respectively hinged to connecting plates 10, and the two connecting plates 10 are arranged oppositely, a rolling assembly 11 is arranged at the upper ends of the two connecting plates 10, and the upper ends of the two connecting plates 10 and the lower end of the rolling assembly 11 are respectively hinged, and a rotating mechanism 12 for driving the two bidirectional lead screws 6 to rotate synchronously and in the same direction is arranged on one side of the bearing frame 2.

[0024] During use, for a single bearing frame 2, the rotating mechanism 12 drives the two bidirectional lead screws 6 to rotate synchronously and in the same direction. Under the action of the guiding mechanism, the two moving blocks 7 on the bidirectional lead screw 6 will move closer to or away from each other when the bidirectional lead screw 6 rotates. When the two moving blocks 7 move closer to each other, they will respectively push the rolling assembly 11 upward through the two connecting plates 10 hinged thereon. When the two moving blocks 7 move away from each other, they will respectively pull the rolling assembly 11 downward through the two connecting plates 10 hinged thereon; when it is necessary to remove the prefabricated component 1 from the bearing frame 2, first loosen the prefabricated component 1 through the vertical fixing mechanism 3 and the horizontal fixing mechanism 4, and then drive the bidirectional lead screw 6 to rotate through the rotating mechanism 12 so that the rolling assembly 11 moves upward.

The prefabricated component 1 can be conveniently translated under the rolling action of the rolling assembly 11, and the staff can directly and conveniently pull the prefabricated component 1 outwards from the rolling assembly 11, so that the prefabricated component 1 can be taken out of the bearing frame 2. Therefore, driving the bidirectional lead screw 6 to rotate through the rotating mechanism 12 so that the rolling assembly 11 moves upward can enable the rolling assembly 11 to jack the prefabricated component 1 upward by a certain distance, so that the prefabricated component 1 is separated from the bearing frame 2, thereby enabling the prefabricated component 1 to be conveniently translated under the rolling action of the rolling assembly 11, and further facilitating the staff to directly take out the prefabricated component 1 from the bearing frame 2 and facilitating the removal process of the prefabricated component 1 from the bearing frame 2, solving the problem in the related technology that it is not convenient to remove the prefabricated component 1 from the bearing frame 2.

The guiding groove 9 is formed in the inner bottom of the bracket 5, and the guiding block 8 is slidably arranged in the guiding groove 9. The guiding block 8 always slides in the guiding groove 9, which can play a guiding role for the moving block 7, so that the moving block 7 can stably perform horizontal linear motion on the bidirectional lead screw 6.

[0026] Refer to Figure 2 、 Figure 3 and Figure 4 , the rolling assembly 11 includes a mounting frame 111. The mounting frame 111 is arranged at the upper ends of two connecting plates 10, and the upper ends of the two connecting plates 10 are respectively hinged to the lower surface of the mounting frame 111.

[0027] Refer to Figure 2 and Figure 3 , the rotation mechanism 12 includes two first gears 121 and a second gear 122. The two first gears 121 are respectively fixedly connected to one end of two bidirectional lead screws 6. The second gear 122 is rotatably connected to one side of the bearing frame 2, and the second gear 122 is located between the two first gears 121. The outer diameters of the two first gears 121 are the same, the outer diameter of the two first gears 121 is smaller than the outer diameter of the second gear 122, and the two first gears 121 are meshed with the second gear 122. A driving member for driving the second gear 122 to rotate is arranged on one side of the second gear 122. The driving member includes a turntable 123. The turntable 123 is fixedly connected to one side of the second gear 122. A tightening mechanism is arranged on the turntable 123. The tightening mechanism includes a mounting plate 124.

The second gear 122 will drive the two first gears 121 on both sides to rotate synchronously in the same direction. The two first gears 121 will respectively drive the two bidirectional lead screws 6 to rotate synchronously in the same direction. When the roller 112 is moved upward by a certain distance, stop rotating the turntable 123, and then tighten the tightening bolt 125 to fix the turntable 123, so that the position of the roller 112 at this time can be fixed, improving the stability of the roller 112 after adjustment and making it more convenient for the precast member 1 to be translated on the roller 112.
