Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a stair railing embedded part for prefabricated buildings. Background Technology

[0002] Prefabricated construction is a modern industrialized production method that involves manufacturing building components such as floor slabs, wall panels, stairs, and balconies in a factory, then transporting them to the construction site for assembly and installation. Embedded components, on the other hand, are metal components that require pre-installation, primarily used to connect and secure building parts such as stairs and railings, providing fixing points for the railings during subsequent installation and construction.

[0003] In existing stair railing embedded parts used in prefabricated buildings, the installation of stair railings typically requires workers to use impact drills to make holes. This drilling damages the building surface, and the vibration from the impact drill can cause the mounting holes to shift, resulting in inaccurate railing placement and affecting the installation effect. Furthermore, during assembly, the railings are usually connected to the embedded parts by welding, which is time-consuming and labor-intensive. Once welding is completed, any deviations during the overall installation of the railing cannot be adjusted accordingly. Moreover, if problems or damage occur later, because the embedded parts are located in the main building structure and the railings are fixed to them, the railings cannot be disassembled for repair or replacement, affecting their functionality and creating safety hazards in the building. Utility Model Content

[0004] The purpose of this utility model is to provide a stair railing embedded part for prefabricated buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stair railing embedded part for prefabricated buildings, comprising:

[0006] A connecting plate, wherein a connecting block is fixedly connected to the top of the connecting plate, and a railing body is provided on the top of the connecting block;

[0007] An embedded rod is fixed to the bottom of the connecting plate, and a reinforcing component is provided on the outside of the embedded rod to improve the installation stability of the embedded part;

[0008] A threaded rod is fixed to the bottom of the railing body. The pre-embedded rod has a threaded groove inside, and the outer side of the threaded rod is threaded to the inner wall of the threaded groove.

[0009] A connecting seat is fixed to the outside of the connecting block. A rotating component is provided on the inside of the connecting seat. Four rubber pads are fixedly connected to the outside of the connecting block.

[0010] A positioning component is disposed on the outside of the rubber pad, and four sets of limiting components are symmetrically disposed on the outside of the connecting block;

[0011] A steel ring is disposed at one end of the rotating assembly, an adjusting component is disposed on the outer side of the steel ring, and a fixing component is disposed on the outer side of the rotating assembly.

[0012] Preferably, the reinforcing component includes an anchor block fixed to one end of the pre-embedded rod, four reinforcing ribs are fixedly connected to the outer side of the anchor block, and four sets of reference holes are symmetrically arranged on the outer side of the connecting plate.

[0013] Preferably, the rotating assembly includes a first rotating ring rotating at one end of the connecting seat, a second rotating ring rotatably connected to the other end of the connecting seat, and the other end of the first rotating ring rotatably connected to one end of the steel ring.

[0014] Preferably, the positioning component includes a positioning block fixed to one side of the rubber pad, and a positioning groove is provided on the outer side of the railing body, with the outer side of the positioning block slidably connected to the inner side of the positioning groove.

[0015] Preferably, the limiting component includes a locking block that rotates to the outside of the connecting block, a limiting groove is formed on the outside of the railing body, and the outside of the locking block is engaged with the inner wall of the limiting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses a reference hole to align the connecting plate with the marked pre-embedded position, determining the installation position of the pre-embedded part. Concrete is then poured to ensure a tight bond between the concrete and the pre-embedded rod, simultaneously fixing it to the building structure. The pre-embedded rod eliminates the problem of misalignment caused by drilling, improving the accuracy of the installation. By aligning the threaded rod with the threaded groove and rotating the railing body along the axis of the threaded groove, the railing body is gradually tightened, achieving initial fixation. Tightening the steel ring enables self-locking of the rotating assembly. Then, rotating the bolt with the handle connects it to the upper and lower ends of the fixing frame, locking the adjusting block inside the fixing frame and preventing movement. This completes the connection between the railing body and the pre-embedded part, overcoming the drawback of welding preventing separation. This design allows for railing replacement and adjustment while ensuring the stability of the connection between the railing and the pre-embedded part. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 As shown, a stair railing embedded part for prefabricated buildings includes a connecting plate 1 for improving the overall structural strength of the embedded part; a connecting block 3 is fixedly connected to the top of the connecting plate 1, and a railing body 4 is provided on the top of the connecting block 3; an embedded rod 2 is fixed to the bottom of the connecting plate 1 for embedding in the building body, and the concrete is poured to make the concrete tightly bonded to the embedded rod 2, while forming a fixed bond with the building body; a reinforcing component 5 is provided on the outside of the embedded rod 2 to improve the installation stability of the embedded part.

[0027] A threaded rod 6 is fixed to the bottom of the railing body 4. A threaded groove 7 is opened inside the pre-embedded rod 2. The outer side of the threaded rod 6 is threaded to the inner wall of the threaded groove 7. The lengths of the threaded rod 6 and the threaded groove 7 are designed so that when they are fully connected and cannot be tightened, the railing body 4 will be in the position corresponding to the top of the connecting block 3. A connecting seat 8 is fixed to the outer side of the connecting block 3. A rotating component 9 is provided on the inner side of the connecting seat 8. Four rubber pads 10 are fixedly connected to the outer side of the connecting block 3. One end of the rubber pad 10 is fixed to the outer side of the connecting block 3, while the other end can undergo a certain deformation when there is no limit on the outer side due to the characteristics of the rubber material. A positioning component 11 is provided on the outer side of the rubber pad 10. Four sets of limiting components 12 are symmetrically provided on the outer side of the connecting block 3. A steel ring 13 is provided at one end of the rotating component 9 and is used to drive the rotating component 9 to open or tighten. An adjusting component 14 is provided on the outer side of the steel ring 13, and a fixing component 15 is provided on the outer side of the rotating component 9.

[0028] The reinforcing component 5 includes an anchor block 51 fixed to one end of the embedded rod 2, which increases the connection area between the embedded rod 2 and the building structure, thereby improving the stability of the embedded rod 2 after it is embedded. Four reinforcing ribs 52 are fixedly connected to the outside of the anchor block 51, and their two ends are connected to the anchor block 51 and the connecting plate 1 respectively. They are made of high-strength metal and are used to improve the overall strength of the embedded parts. Four sets of reference holes 53 are symmetrically arranged on the outside of the connecting plate 1. By observing the reference holes 53, the connecting plate 1 can be matched with the markings of the embedded position to determine the installation position of the embedded parts and improve the installation accuracy.

[0029] The rotating assembly 9 includes a first rotating ring 91 that rotates at one end of the connecting seat 8, and a second rotating ring 92 that is rotatably connected to the other end of the connecting seat 8. The other end of the first rotating ring 91 is rotatably connected to one end of the steel ring 13. After the first rotating ring 91 and the second rotating ring 92 are tightened, pressure is applied to the rubber pad 10 to fix the positioning assembly 11 and limit the limiting assembly 12.

[0030] The positioning component 11 includes a positioning block 111 fixed to one side of the rubber pad 10. A positioning groove 112 is provided on the outer side of the railing body 4. The outer side of the positioning block 111 is slidably connected to the inner side of the positioning groove 112. The positioning block 111 is aligned and inserted into the inner side of the positioning groove 112, so that the connecting block 3 and the railing body 4 form a fixed connection.

[0031] The limiting component 12 includes a locking block 121 that rotates outside the connecting block 3. A limiting groove 122 is provided on the outer side of the railing body 4. The outer side of the locking block 121 engages with the inner wall of the limiting groove 122. The locking block 121 rotates and fits against the inner side of the limiting groove 122, thereby reinforcing the connection between the connecting block 3 and the railing body 4. The locking block 121 can limit the railing body 4, preventing it from rotating laterally, and thus preventing the threaded rod 6 from rotating and separating from the threaded groove 7.

[0032] The adjustment assembly 14 includes a connecting frame 141 that rotates at one end of the steel ring 13. One end of the connecting frame 141 is fixedly connected to an adjustment block 142. By moving the adjustment block 142, the connecting frame 141 rotates. The other end of the connecting frame 141 is rotatably connected to one end of the second rotating ring 92. When one end of the connecting frame 141 rotates, it uses one end of the second rotating ring 92 as a fulcrum.

[0033] The fixing component 15 includes a fixing frame 151 fixed to the outside of the second rotating ring 92. The inner wall of the fixing frame 151 is threaded with a bolt 152. One end of the bolt 152 is fixedly connected to a handle 153. By rotating the bolt 152 with the handle 153, the bolt 152 is connected to the upper and lower ends of the fixing frame 151. At this time, the bolt 152 is attached to the outside of the adjusting block 142. It should be noted that one end of the adjusting block 142 is provided with an arc-shaped part, which can fix the position of the adjusting block 142 and prevent it from coming off from one side of the bolt 152, so that the adjusting block 142 cannot move.

[0034] Working principle: In use, firstly, by observing the reference hole 53, the connecting plate 1 is aligned with the mark of the pre-embedded position to determine the installation position of the pre-embedded part. Then, concrete is poured to ensure a tight bond between the concrete and the pre-embedded rod 2, while simultaneously fixing it to the main building structure. Subsequently, when installing the railing, the threaded rod 6 is aligned with the threaded groove 7. Then, the railing body 4 is rotated to move along the axis of the threaded groove 7. As it rotates, the railing body 4 is gradually tightened, thus completing the initial fixing of the railing body 4. The lengths of the threaded rod 6 and the threaded groove 7 are designed so that when they are fully connected and cannot be tightened, the locking block 121 and the limiting groove 122 are in the corresponding positions. Then, the locking block 121 is rotated to fit against the inner side of the limiting groove 122, and then the positioning block 11 is... 1. Align the inner side of the insertion positioning groove 112 to fix the connection between the connecting block 3 and the railing body 4. Then, rotate the adjusting block 142 counterclockwise. One end of the connecting frame 141 rotates with one end of the second rotating ring 92 as the fulcrum. While the other end rotates, it pulls the steel ring 13 to move, causing the second rotating ring 92 and the first rotating ring 91 to tighten and fit against the rubber pad 10 and the locking block 121. After the adjusting block 142 completes its rotation stroke, the rotating component 9 is self-locked by tightening the steel ring 13. Then, the bolt 152 is rotated by the handle 153. Through the closed loop formed by the fixing frame 151 and the bolt 152, the adjusting block 142 is locked inside the fixing frame 151, so that 142 cannot move. The connection between the railing body 4 and the embedded part is then completed.
