Description

Technical Field

[0001] The embodiments of the present invention relate to the field of building technology, and in particular to a prefabricated partition wall. Background Technology

[0002] Prefabricated building walls are constructed by prefabricating building components in a factory, transporting them to the site, and assembling them using reliable connection methods.

[0003] Existing prefabricated partition walls typically require an embedded intermediate plate in the connectors to achieve thermal and sound insulation, and also to prevent the wall from tipping over. However, when one partition wall is damaged, due to the presence of the intermediate plate, workers need to move each partition wall laterally until a gap is created to remove the damaged one. This connection structure increases the difficulty of later maintenance and replacement. Summary of the Invention

[0004] To address the aforementioned deficiencies in the prior art, embodiments of the present invention provide a prefabricated partition wall. By moving the locking component used to connect two partition walls to the interior of another partition wall, workers can remove the partition wall longitudinally, facilitating its maintenance and replacement.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this embodiment of the invention is to provide a prefabricated partition wall, the partition wall including multiple partition wall bodies, a first connector, a second connector, a locking member and at least one unlocking mechanism;

[0006] The multiple partition wall bodies are arranged horizontally and connected. The first connector and the second connector are installed on the sides of two adjacent partition wall bodies. The adjacent partition wall bodies are connected to each other through the contact of the first connector and the second connector.

[0007] The first connector and the second connector are fixedly connected by a locking member to restrict longitudinal movement between adjacent partition wall bodies;

[0008] The unlocking mechanism includes a first gear, a second gear, a threaded rod, and a control rod;

[0009] One end of the control rod is mounted on the decorative surface of the partition wall body, and the other end is on the first connector or the second connector. The first gear is mounted on the other end of the control rod.

[0010] One end of the threaded rod is mounted on the first connector, and the second gear is mounted on the threaded rod. The locking member is provided with a threaded hole that can mesh with the threaded rod. By rotating the second gear through the first gear, the locking member moves along the direction of the threaded rod through threaded engagement. When unlocking, the movement of the locking member along the threaded rod causes the locking member to move out of the second connector or the first connector.

[0011] Optionally, the first connecting member includes a first sealing block and a first bending plate. The first bending plate is installed on the side of the partition wall body. The first sealing block is installed in a groove structure on the first bending plate. The first sealing block is provided with a first receiving cavity for placing the threaded rod. One end of the threaded rod is connected to the first bending plate.

[0012] The second connector includes a second sealing block and a second bending plate. The second bending plate is installed on the side of the partition wall body, and the second sealing block is installed in the groove structure on the second bending plate. The second sealing block is provided with a second receiving cavity that communicates with the first receiving cavity.

[0013] In the locked state, one end of the locking member is located in the first accommodating cavity, and the other end is located in the second accommodating cavity.

[0014] Optionally, the first connector and the second connector are fixed together along the length of the partition wall body by a plurality of locking members. The second connector and / or the first connector are respectively provided with a plurality of unlocking mechanisms. The locking members are removed from the first connector or the second connector by the unlocking mechanisms so as to separate the two adjacent partition wall bodies.

[0015] Optionally, the distances between the plurality of locking elements are the same.

[0016] Optionally, a countersunk hole is provided on the decorative surface, and one end of the control rod is installed in the countersunk hole.

[0017] Optionally, the countersunk hole is provided with threads for screwing in a support member, through which the partition wall body is removed along the wall surface perpendicular to the partition wall body.

[0018] Optionally, the number of unlocking mechanisms provided on the first connector and the second connector is the same.

[0019] Optionally, the control lever is connected to the first gear by a snap-fit ​​connection.

[0020] Optionally, the threaded hole on the locking member passes through the locking member, and the number of the at least one unlocking mechanism is two; the two unlocking mechanisms are respectively disposed on the first connecting member and the second connecting member, one end of the locking member is opposite to the threaded rod in the first connecting member, and the other end is opposite to the threaded rod in the second connecting member, and the unlocking mechanism is provided with a locking engagement member. When unlocking, the control rod is rotated, and the locking engagement member causes the threaded rod to move toward the locking member, so that the locking member stops moving after engaging with the threaded rod.

[0021] Optionally, the locking engagement member includes a third receiving cavity, a spring, and a mounting hole; the third receiving cavity is disposed within the first connecting member and the second connecting member, the spring is installed within the third receiving cavity, one end of the threaded rod is connected to the spring, the first connecting member and the second connecting member are provided with the mounting hole for communicating the first receiving cavity and the third receiving cavity, and the mounting hole is provided with a thread in the middle;

[0022] The threaded rod includes a first engaging portion, a second engaging portion, and a sliding portion. The first engaging portion is used to engage with the locking member, and the second engaging portion is used to engage with the mounting hole.

[0023] The second engagement part is held in contact with the thread in the mounting hole by the spring, so that the threaded rod moves toward the locking member by the sliding part when it rotates, so as to engage the threaded rod with the locking member, and the threaded rod stops moving by the sliding part.

[0024] This invention provides a prefabricated partition wall, which is connected by locking components. The locking components are horizontally installed inside two partition walls to restrict their longitudinal movement. An unlocking mechanism is also provided inside the partition wall, including a first gear, a second gear, a threaded rod, and a control rod. One end of the control rod is installed on the decorative surface of the partition wall body, and the other end is on a first connecting member. The first gear is installed on the other end of the control rod. One end of the threaded rod is installed on the first connecting member, and the second gear is installed on the threaded rod. The locking component has a threaded hole that meshes with the threaded rod. By rotating the second gear with the first gear, the locking component moves towards the threaded rod through threaded engagement, allowing the locking component connecting the two partition walls to move into the other partition wall. This enables workers to remove the partition wall longitudinally, facilitating its maintenance and replacement. Attached Figure Description

[0040] Figure 1 An assembled partition wall is shown, comprising multiple partition wall bodies 1, a first connector 3, a second connector 2, a locking member 4, and an unlocking mechanism 5; the multiple partition wall bodies 1 are arranged horizontally and connected, the first connector 3 and the second connector 2 are installed on the side of the partition wall body 1, and adjacent partition wall bodies 1 are connected by contact between the first connector 3 and the second connector 2; the first connector 3 and the second connector 2 are connected by the locking member 4 to restrict longitudinal movement between adjacent partition wall bodies 1.

[0041] In this context, "horizontal" refers to the direction parallel to the decorative surface 7, and "vertical" refers to the direction perpendicular to the decorative surface 7. The first connector 3 and the second connector 2 are protective components installed on the sides of the partition wall body 1, their shapes adapted to the partition wall body 1 or customized according to actual installation requirements. During installation, the sides of adjacent partition wall bodies 1 are connected together via the first connector 3 or the second connector 2. This connection aims to seal the gap between the two partition wall bodies 1 to achieve thermal insulation and soundproofing. The first connector 3 and the second connector 2 are connected by a locking member 4. One end of the locking member 4 is installed inside the first connector 3, and the other end is installed inside the second connector 2. The locking member 4 restricts the longitudinal freedom of the two connected partition wall bodies 1, preventing them from tipping over. The locking member 4 is connected to an unlocking mechanism 5, which can completely move the locking member 4 into the first connector 3 or the second connector 2, allowing the two adjacent partition wall bodies 1 to move longitudinally. When disassembling the partition wall body 1, each individual partition wall body 1 can be directly removed. Among them, reference Figure 2 and Figure 3 In one implementation, the unlocking mechanism 5 includes a first gear 503, a second gear 502, a threaded rod 501, and a control rod 504. One end of the control rod 504 is mounted on the decorative surface 7 of the partition wall body 1, and the other end is mounted on the first connecting member 3. The first gear 503 is mounted on the other end of the control rod 504. One end of the threaded rod 501 is mounted on the first connecting member 3, and the second gear 502 is mounted on the threaded rod 501. The locking member 4 has a threaded hole that meshes with the threaded rod 501. By rotating the second gear 502 through the first gear 503, the locking member 4 moves towards the threaded rod 501 through threaded engagement. The unlocking mechanism 5 can be installed inside the first connecting member 3. The control rod 504 and the first gear 503 are keyed together, and the threaded rod 501 and the second gear 502 are keyed together. The threaded rod 501 is mounted on the first connecting member 3, restricting its movement. The threaded rod 501 and the locking member 4 are always engaged. The locking member 4 can have various shapes, such as cylindrical, triangular prism, or quadrangular prism. In one implementation, the locking member 4 is a rectangular rod, which effectively restricts the rotation of the locking member 4 within the second connecting member 2, facilitating quick removal of the locking member 4 from the second connecting member 2. When the control lever 504 is rotated, the locking member 4 moves towards the threaded rod 501 until the portion of the locking member 4 located within the second connecting member 2 is completely moved into the first connecting member 3. The contact surface between the first connecting member 3 and the second connecting member 2 can be an inclined plane or a vertical plane. In one implementation, the contact surface between the first connecting member 3 and the second connecting member 2 is perpendicular to the partition wall body 1, which makes installation between the partition wall bodies 1 more convenient.

[0042] One implementation involves a countersunk hole 6 on the decorative surface 7, which connects to the interior of the first connecting member 3. The control rod 504 is installed within the countersunk hole 6, improving the aesthetics of the decorative surface 7. In one embodiment, the countersunk hole 6 can be filled with a sealing cap made of the same material as the outer sealing plate 102. The sealing cap is threaded into the countersunk hole 6, abutting against one end of the control rod 504 to restrict its rotation. When the control rod 504 is needed, the sealing cap is unscrewed. In another implementation, the control rod 504 can be snapped into the first gear 503. The first gear 503 can be installed on the first connecting member 3. When the locking member 4 needs to be moved into the first connecting member 3, the control rod 504 is inserted into the countersunk hole 6. After the partition wall is installed, the control rod 504 is removed.

[0043] Among them, reference Figure 3 In one embodiment of the present invention, the first connecting member 3 includes a first sealing block 301 and a first bending plate 302. The first bending plate 302 is installed on the side of the partition wall body 1, and the first sealing block 301 is installed in a groove structure on the first bending plate 302. The first sealing block 301 is provided with a first receiving cavity for placing the threaded rod 501, and one end of the threaded rod 501 is connected to the first bending plate 302. The second connecting member 2 includes a second sealing block 201 and a second bending plate 202. The second bending plate 202 is installed on the side of the partition wall body 1, and the second sealing block 201 is installed in a groove structure on the second bending plate 202. The second sealing block 201 is provided with a second receiving cavity communicating with the first receiving cavity.

[0044] In this embodiment, the partition wall body 1 includes two outer sealing plates 102 and a middle plate 101. The middle plate 101 is installed between the two outer sealing plates 102, and the length of the outer sealing plates 102 is greater than that of the middle plate 101, making the side of the partition wall body 1 a groove structure. The first bending plate 302 and the second bending plate 202 can be configured as U-shaped structures. The first sealing block 301 is installed in the groove structure of the first bending plate 302, and the second sealing block 201 is installed in the groove structure of the second bending plate 202. The first sealing block 301 and the second sealing block 201 are used for fireproofing, sound insulation, and heat insulation, and the specific materials used can be changed according to actual conditions. One end of the locking member 4 is located in the first accommodating cavity, and the other end is located in the second accommodating cavity. Both the first and second accommodating cavities are engaged with the locking member 4 to restrict longitudinal movement between two adjacent partition wall bodies 1. The locking member 4 can be made of materials such as steel or plastic to enhance the connection strength.

[0045] In one embodiment of the present invention, the first connecting member 3 and the second connecting member 2 are fixed together by a plurality of locking members 4. In one implementation, the unlocking mechanism 5 is disposed on the first connecting member 3 or the second connecting member 2, and the locking members 4 are arranged in the length direction of the partition wall, wherein the length direction is vertical to the ground. When disassembling the partition wall body 1, it is easier to use the unlocking mechanism 5 to move the locking members 4 into the first connecting member 3 or the second connecting member 2. In another implementation, refer to... Figure 4 Both the second connecting member 2 and the first connecting member 3 are equipped with the unlocking mechanism 5. The locking member 4 on the second connecting member 2 is removed from the first connecting member 3 through the unlocking mechanism 5. One end of the threaded rod 501 on the second connecting member 2 is mounted on the second bending plate 202, and the other end is threadedly connected to the locking member 4. When the threaded rod 501 is rotated, the locking member 4 moves in the direction of the threaded rod 501. The presence of unlocking mechanisms 5 on both sides allows for more even force distribution on the partition wall body 1. The spacing between the multiple locking members 4 can be varied. In one implementation, the spacing between the multiple locking members 4 can be the same or they can be symmetrical. This arrangement allows for more even force distribution on the sides of the partition wall body 1 when subjected to longitudinal force, thus improving its service life. The first connecting member 3 and the second connecting member 2 are equipped with the same number of unlocking mechanisms 5. Similarly, this arrangement allows for more even force distribution on the sides of the partition wall body 1 when subjected to longitudinal force.

[0046] Among them, reference Figure 3 , Figure 4Considering that if the unlocking mechanism 5 is only provided at one end of the locking member 4, when the partition wall is damaged and the unlocking mechanism 5 on the first connecting member 3 or the second connecting member 2 is also damaged, the partition wall body 1 will not be able to be removed longitudinally, and only the existing removal method can be used. Therefore, in one implementation, the threaded hole on the locking member 4 passes through the locking member 4, and the number of at least one unlocking mechanism 5 is two; the two unlocking mechanisms 5 are respectively provided on the first connecting member 3 and the second connecting member 2. One end of the locking member 4 is opposite to the threaded rod in the first connecting member, and the other end is opposite to the threaded rod 501 in the second connecting member 2. The unlocking mechanism 5 is provided with a locking engagement member. When unlocking, rotating the control rod 504 causes the locking engagement member to move the threaded rod 501 toward the locking member 4, so that the locking member 4 stops moving after engaging with the threaded rod 501. Among them, one end of the threaded hole is opposite to the threaded rod 501 located in the first connecting member 3, and the other end is opposite to the threaded rod 501 located in the second connecting member 2. In this configuration, the two threaded rods 501 are in abutting position against the locking member 4. The second gear 502 is mounted on the first connecting member 3 or the second connecting member 2. The second gear 502 and the threaded rods 501 are connected by a key, and the threaded rods 501 can slide in the second gear 502.

[0047] The locking engagement component may include a third accommodating cavity, a spring, and a mounting hole. The third accommodating cavity is disposed within the first connecting member 3 and the second connecting member 2. The spring is installed within the third accommodating cavity. One end of the threaded rod 501 is connected to the spring. The mounting hole is provided on the first connecting member 3 and the second connecting member 2 to connect the first accommodating cavity and the third accommodating cavity. A thread is provided in the middle of the mounting hole. The threaded rod 501 includes a first engaging portion 4. 01. The second engaging part 403 and the sliding part 402, wherein the first engaging part 401 is used to engage with the locking member 4, and the second engaging part 403 is used to engage with the mounting hole; the second engaging part 403 is kept in contact with the thread in the mounting hole by the spring, so that the threaded rod 501 moves toward the locking member 4 by the sliding part 402 when rotating, so as to realize the engagement of the threaded rod 501 with the locking member 4, and the sliding part causes the threaded rod 501 to stop moving relative to the locking member 4 in the length direction.

[0048] When the unlocking mechanism 5 on the second connecting member 2 is damaged, the first gear 503 cannot drive the second gear 502 to rotate, preventing the threaded rod 501 on the second connecting member 2 from moving the locking member 4 into the second connecting member 2. In this case, the threaded rod 501 within the first connecting member 3 can be used to move the locking member 4 into the first connecting member 3. The first connecting member 3 has a mounting hole with a threaded section in the middle and no thread on the remaining portion. For details on the structure of the threaded rod 501 and the mounting hole, please refer to [reference needed]. Figure 6 and Figure 7 The threaded rod 501 is installed in the mounting hole. When the control rod 504 is rotated, the first gear 503 drives the threaded rod 501 to rotate. Since the threaded rod 501 is threadedly connected to the mounting hole, the threaded rod 501 moves towards the locking member 4 during rotation, causing the spring at the end to deform. At this time, the threaded rod 501 engages with the locking member 4, and the thread on the threaded rod 501 disengages from the thread inside the mounting hole. When the threaded rod 501 continues to rotate, since the movement of the threaded rod 501 along its length is restricted, the threaded rod 501 only rotates under the drive of the first gear 503. During the rotation, the locking member 4 moves. Since the locking member 4 is a rectangular rod, its rotation is restricted, causing the locking member 4 to move relative to the threaded rod 501 and continuously move towards the threaded rod 501 until the locking member 4 is completely inserted into the first connecting member 3. At this time, under the action of the spring force, the thread on the threaded rod 501 is always in contact with the thread inside the mounting hole. During the process of reversing the control rod 504, the threaded rod 501 can smoothly engage with the mounting hole. After the partition wall is replaced, the continuous reversing of the control rod 504 can make the locking part 4 move towards the second connecting part 2. During this process, the threaded rod 501 engages with the mounting hole again, causing the threaded rod 501 to move towards the spring and causing the spring to deform again. When the threaded rod 501 disengages from the mounting hole, the threaded rod 501 rotates under the drive of the control rod 504 until the locking part 4 is completely removed from the threaded rod 501.

[0049] The countersunk hole 6 is threaded to allow a support member to be screwed in, enabling the partition wall to be removed longitudinally. The support member can be a rod-shaped structure that is threaded into the countersunk hole 6. When disassembling the partition wall, the countersunk hole 6 serves as a fulcrum, allowing workers to hold the support member and remove the partition wall by hand.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
