Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of positioning and connecting prefabricated building components, and more specifically, relate to a high-precision positioning module for hoisting prefabricated vertical components of prefabricated buildings. Background Art

[0002] Prefabricated vertical components of assembled buildings are building components that are prefabricated in factories and then installed on site. Compared with traditional cast-in-place vertical components, prefabricated vertical components ensure the quality of components and construction quality through standardized design and factory production, thereby improving the overall quality and construction efficiency of the project. At the same time, the production of its components is carried out in the factory, the material and energy consumption are controllable, the construction phase consumes less building materials and electricity, and construction dust and construction waste are greatly reduced. Prefabricated vertical components are highly favored in construction projects due to their excellent performance and economic advantages. However, during the construction process, due to the large size of prefabricated vertical components, their weight is also large, which makes the lifting and positioning of the construction technology more demanding, and alignment deviations are prone to occur, affecting the construction accuracy and efficiency.

[0003] In the prior art, a Chinese patent with document number CN115594061A discloses a concrete slab hoisting positioning mechanism and positioning method, wherein the positioning mechanism includes a horizontal plate, two groups of support arms and a group of telescopic devices. The side wall is suspended by the hoisting mechanism. At the same time, the two groups of support arms on the bottom plate are supported on the surface of the side wall, so that the side wall forms a three-point support structure, and the angle between the side wall and the bottom plate is not greater than 90°, and the support point of the support arm to the side wall is located directly above the installation position on the bottom plate; at the same time, the lower end of the side wall is pulled by the telescopic device to move the lower end of the side wall to the middle side of the bottom plate, and finally the two groups of support arms serve as the support points of the side wall, and the pulling force of the hoisting mechanism and the telescopic device acts on the upper and lower ends of the side wall respectively, so that the side wall is vertically aligned with the installation position on the bottom plate, and gradually lowered for installation.

[0004] The positioning structure of the Chinese patent with document number CN115594061A uses a mechanical structure to replace manpower for side wall installation positioning, which can save manpower, but it still does not solve some problems of the existing positioning structure: (1) The positioning structure is relatively complex and requires special personnel to install, which requires a lot of manpower; (2) The installation of the positioning structure depends on the surrounding walls or floors. After its removal, it will also cause certain damage to the surrounding walls or floors, and at the same time, affect the subsequent connection operations; (3) The positioning structure is not compatible with the connection structure, and the connection structure needs to be installed later. Utility Model Content

[0005] In view of the above defects or improvement needs of the prior art, the utility model provides a high-precision positioning module for the hoisting of prefabricated vertical components of assembled buildings. By integrating the positioning component into the supporting component, the prefabricated vertical component body being hoisted can be quickly and accurately aligned with the prefabricated vertical component body that has been fixed below under the action of the positioning component, thereby further improving the on-site assembly speed. At the same time, the supporting component and the positioning component have a simple structure and can be prefabricated simultaneously with the assembled prefabricated vertical components, saving labor, further reducing costs, and improving overall construction efficiency.

[0012] The movable steel ball is embedded in the positioning groove at the upper end of the first supporting member.

[0013] Furthermore, a plurality of the positioning grooves are respectively arranged directly above and directly below the prefabricated vertical component body.

[0014] Furthermore, the positioning groove at the upper end of the first support member is a groove and is adapted to the movable steel ball, so that the movable steel ball is partially exposed from the upper surface of the first support member.

[0016] Furthermore, the positioning grooves at the upper end of the first support member and the bottom end of the second support member include columnar grooves of regular polygonal or irregular shapes, and the aperture of the groove is not less than the outer diameter of the movable steel ball.

[0017] Furthermore, the positioning groove at the bottom end of the second support member is a groove, and when the second support member is tightly fitted with the first support member, the movable steel ball partially exposed from the upper surface of the first support member completely falls into the positioning groove at the bottom end of the second support member.

[0018] Furthermore, the movable steel ball is made of high-strength steel such as high-carbon chromium steel.

[0019] Furthermore, the surface of the movable steel ball is coated with a drag reducing material, and the drag reducing material is prepared by a fluid material such as grease or a solid material such as polytetrafluoroethylene.

[0021] Furthermore, the first support member and the second support member are made of metal materials such as steel.

[0022] Furthermore, the first support member and the second support member are respectively preset at the upper end and the bottom end of the prefabricated vertical component body by means of bolting or welding.

[0023] Furthermore, the cross-sectional dimensions of the upper surface of the first support member and the lower surface of the second support member may exceed the cross-sectional dimensions of the upper end surface and the bottom end surface of the prefabricated vertical component body.

[0024] Furthermore, the upper surface of the first support member and the lower surface of the second support member are parallel.

At the same time, the supporting component and the positioning component have a simple structure and can be prefabricated at the same time as the prefabricated vertical component, saving labor, further reducing costs, and improving overall construction efficiency.

[0027] (2) The positioning module of the utility model makes fine adjustments to the upper prefabricated vertical component body so that the lower movable steel ball partially falls into the positioning groove, thereby utilizing the gravity of the upper prefabricated vertical component body itself and the drag-reducing material coated on the outer surface of the movable steel ball to avoid direct collision between the upper first support member and the lower second support member when falling, thereby achieving rapid and accurate alignment and position locking of the two prefabricated vertical components, significantly improving operating efficiency and reducing the number of workers and physical exertion.

[0028] (3) The positioning module of the utility model uses high-strength steel such as high-carbon chromium steel to prepare the movable steel ball and covers the outer surface with drag-reducing material to reduce possible collision damage, and improves the positioning accuracy by cooperating with the hemispherical positioning groove.
