[0002] Prefabricated building components are building components that are manufactured in advance in factories or production bases and then assembled and installed on site. These components can include wall panels, floor slabs, columns, beams, stairs, exterior wall panels and other elements of various shapes and functions. The use of straight thread joints and positioning sleeves in prefabricated building components is a common connection method used to ensure accurate positioning and connection of components during installation.

[0003] Traditional prefabricated building components use straight thread joint positioning sleeves to fix and install the straight thread joints in the appropriate position of the prefabricated components. This may involve screwing the straight thread joint into the pre-designed hole of the component, ensuring that it is flush with the surface of the component or embedded in it. The advantages of using straight thread joint positioning sleeves include simple connection, fast installation, accurate positioning, and stable structure. This connection method is usually used for prefabricated building components that require highly precise positioning and stable connection, such as wall panels, floor slabs, columns, etc.

[0004] However, the threaded sleeve of the straight threaded joint positioning sleeve used in traditional prefabricated building components cannot be positioned and sealed during the component production process, resulting in concrete slurry contaminating the sleeve. The contamination will have an adverse effect on the stability and durability of the building structure. The penetration and corrosion of harmful substances may cause degradation and damage of building materials, thereby affecting the safety and service life of the building. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a straight threaded joint positioning sleeve for prefabricated building components, aiming to improve the problem that the threaded sleeve of the traditional straight threaded joint positioning sleeve for prefabricated building components cannot be positioned and sealed during the component production process, resulting in concrete slurry contaminating the sleeve, and the contamination will have an adverse effect on the stability and durability of the building structure. The penetration and corrosion of harmful substances may cause degradation and damage of building materials, thereby affecting the safety and service life of the building.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a straight thread joint positioning sleeve for prefabricated building components, including a positioning base plate, a straight thread sleeve is arranged on the upper surface of the positioning base plate, a fixing bolt is threadedly connected to the inside of the positioning base plate, a turntable is rotatably connected to the top of the fixing bolt, a plurality of convex teeth are fixedly connected to the side wall of the turntable, a clamping block is fixedly connected to the top of the turntable, a plurality of grooves are provided inside the clamping block, a rubber plug is arranged on the outer wall of the fixing bolt, and a connecting assembly is arranged on the side wall of the straight thread sleeve.

[0007] Furthermore, the connecting assembly includes a bottom edge, and the bottom edge is fixedly connected to the side wall of the straight thread sleeve.

[0008] Furthermore, a rotating column is rotatably connected inside the bottom edge, and a rotating shaft is rotatably connected to the top of the rotating column.

[0013] Furthermore, a second spring is fixedly connected to the bottom of the top shaft, and the second spring is slidably connected to the inside of the first slide groove.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the rubber plug is firstly sleeved on the surface of the fixing bolt, and then the threaded connection between the rubber plug and the convex teeth is used to make the rotating head rotate on the top of the fixing bolt so that the clamping block locks the rubber plug, which can prevent the concrete slurry from contaminating the sleeve.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a straight thread joint positioning sleeve for a prefabricated building component, comprising a positioning base plate 1, a straight thread sleeve 2 is arranged on the upper surface of the positioning base plate 1, a fixing bolt 4 is threadedly connected to the inner surface of the positioning base plate 1, a rotating head 5 is rotatably connected to the top of the fixing bolt 4, a plurality of convex teeth 6 are fixedly connected to the side wall of the rotating head 5, a clamping block 7 is fixedly connected to the top of the rotating head 5, a plurality of grooves 8 are opened inside the clamping block 7, a rubber plug 3 is arranged on the outer wall of the fixing bolt 4, and a connecting component is arranged on the side wall of the straight thread sleeve 2.

[0024] Specifically, when it is necessary to fix the rubber plug 3 on the surface of the fixing bolt 4, first rotate the rotating head 5. While the rotating head 5 is rotating, it drives multiple convex teeth 6 on its surface to rotate synchronously. While the convex teeth 6 are rotating, the convex surface of its surface can perform the first step of engaging the rubber plug 3 to ensure the connection between the rubber plug 3 and the fixing bolt 4. Through the rotation of the rotating head 5, multiple blocking blocks 7 on its side wall follow the synchronous rotation. Through the rotation of the blocking blocks 7, the grooves 8 provided inside them are engaged with the rubber plug 3 in the second step, further enhancing the stability of the connection. This structural design can not only effectively block the pollution of the sleeve by concrete slurry, but also ensure that the fixing structure of the rubber plug 3 is more stable, and at the same time will not interfere with the positioning and installation process of the prefabricated components. Through such a fixing method, the structural stability of the prefabricated components can be ensured, their service life can be improved, and the quality and safety of the construction project can also be guaranteed.

[0025] Reference Figure 3The connecting component includes a bottom edge 9, which is fixedly connected to the side wall of the straight threaded sleeve 2. A rotating column 10 is rotatably connected inside the bottom edge 9. A rotating shaft 11 is rotatably connected to the top of the rotating column 10. A screw 12 is fixedly connected to the bottom of the rotating shaft 11. The screw 12 is threadedly connected to the inside of the rotating column 10. A slide groove 18 is provided inside the rotating column 10. A slide groove 17 is provided inside the positioning base plate 1. A spring 13 is fixedly connected to the bottom of the screw 12. The spring 13 is slidably connected to the inside of the slide groove 18. One end of the spring 13 is fixedly connected to a top shaft 14. A plurality of sliders 15 are fixedly connected to the side wall of the top shaft 14. A spring 16 is fixedly connected to the bottom of the top shaft 14. The spring 16 is slidably connected to the inside of the slide groove 17.

[0026] Specifically, first rotate the shaft 11. The rotation of the shaft 11 simultaneously drives the screw 12 at its bottom to rotate synchronously. Through the threaded connection relationship between the screw 12 and the rotating column 10, the screw 12 moves downward inside the rotating column 10. The movement of the screw 12 simultaneously pushes the top shaft 14 to slide inside the second slide groove 18. The top shaft 14 then causes the sliders 15 on both sides to slide, thereby realizing the engagement or unlocking of the positioning base plate 1. At the same time, the sliding of the spring second 16 in the first slide groove 17 and the sliding of the spring one 13 in the second slide groove 18 can quickly reset the top shaft 14 to its initial position. This design makes the disassembly and assembly of the straight threaded sleeve 2 very quick and efficient, and improves the efficiency of maintenance and replacement. This not only makes the maintenance of prefabricated components more convenient, but also further improves the practicality and sustainability of the overall prefabricated components.

[0027] Working principle: when it is necessary to fix the rubber plug 3 on the surface of the fixing bolt 4, first rotate the rotating head 5. When the rotating head 5 rotates, it drives multiple convex teeth 6 on its surface to rotate synchronously. When the convex teeth 6 rotate, the convex surface of its surface can engage the rubber plug 3 in the first step. Through the rotation of the rotating head 5, multiple clamping blocks 7 on its side wall follow the synchronous rotation. Through the rotation of the clamping block 7, the groove 8 provided inside it can engage with the rubber plug 3 in the second step. This structure can block the concrete slurry from contaminating the sleeve. At the same time, the fixing structure of the rubber plug 3 is more stable and will not interfere with the positioning of the prefabricated part. When it is necessary to disassemble and assemble the straight thread sleeve 2, rotate the rotating head 5. The shaft 11 rotates, and the screw 12 at the bottom thereof is driven to rotate synchronously. Through the threaded connection between the screw 12 and the rotating column 10, the screw 12 moves downward inside the rotating column 10. While the screw 12 moves, it pushes the top shaft 14 to slide inside the second slide groove 18. The top shaft 14 then causes the sliders 15 on both sides to slide, thereby the positioning base plate 1 can be engaged or unlocked, and the top shaft 14 can be quickly reset by sliding the spring second 16 inside the slide groove one 17 and the spring one 13 inside the slide groove two 18, thereby realizing the rapid disassembly and assembly of the straight thread sleeve 2, improving the maintenance efficiency, and further improving the practicality of this prefabricated component.
