[0002] Prefabricated walls refer to a building system in which the components of the building walls are prefabricated in the factory and then assembled and installed on site. This construction method can significantly improve the construction efficiency, quality control and safety of construction projects through factory production and modular design. The development of prefabricated walls has gone through several stages. Initially, prefabricated construction technology was mainly used in industrial plants, storage facilities and other building types. With the continuous advancement of technology and the support of relevant policies, prefabricated construction technology has been more widely promoted and applied, and has gradually been applied in various types of buildings. Prefabricated walls are mainly used in residential buildings, commercial buildings, public facilities and other fields. In various types of buildings, prefabricated walls can provide efficient and reliable building solutions.

[0003] As a modern and efficient construction technology, prefabricated and assembled walls have important application prospects. Through factory production and modular design, prefabricated and assembled walls can improve the construction efficiency, quality control and safety of construction projects, and meet the construction industry's demand for efficient, energy-saving and environmentally friendly construction methods and materials. In the prior art, prefabricated and assembled walls do not have complete positioning measures during assembly, resulting in the need for individuals to perform manual calibration during the installation process. On the one hand, due to manual operation, it is difficult to ensure the accuracy of the installation, resulting in problems such as tilting or misalignment of the wall. On the other hand, during the manual calibration process, due to the heavy weight of the wall, it is easy to cause injuries to workers. In response to the above problems, the present invention provides a prefabricated and assembled wall for construction. Summary of the invention

[0030] like Figure 1-Figure 11 As shown, this embodiment discloses a prefabricated assembled wall, including a wall 1, on which is provided:

[0031] The positioning mechanism includes four groups of first guide shells 2 and second guide shells 3 arranged along the depth direction of the wall 1. The first guide shells 2 and the second guide shells 3 are set on the wall 1. The first guide shells 2 and the second guide shells 3 are slidably matched with the positioning guide rails 4. When the positioning guide rails 4 slide along the first guide shells 2 and the second guide shells 3, the positioning guide rails 4 connect the two assembled walls 1 together and align the two walls 1.

[0032] Specifically, Fig.11 As shown, when the two walls 1 are assembled up and down, a positioning guide rail 4 is slidably fitted on the upper wall 1, and the positioning guide rail 4 slides downward along the first guide shell 2 and the second guide shell 3 on the upper wall 1, and the positioning guide rail 4 will slide into the first guide shell 2 and the second guide shell 3 on the lower wall 1, thereby aligning the upper and lower walls 1 through four relatively arranged positioning guide rails 4, thereby improving the assembly accuracy.

[0033] like Figure 1 , Figure 3 and Fig.11 As shown, two oppositely arranged first guide shells 2 and second guide shells 3 are provided on two oppositely arranged surfaces of the wall 1, and each of the upper and lower arranged first guide shells 2 and second guide shells 3 are slidably matched with the positioning guide rail 4. On the wall 1, the upper and lower arranged first guide shells 2 and second guide shells 3 are a group.

[0034] The positioning mechanism also includes two symmetrically arranged lifting rings 10, which are slidably matched with the wall 1. A connecting rod 11 is detachably installed on both sides of the lifting ring 10. One end of a driving arm 12 is slidably mounted on the connecting rod 11. The other end of the driving arm 12 is slidably matched with a push rod 16, and the push rod 16 is slidably mounted on the wall 1. A ball head rod 13 is fixedly mounted on the driving arm 12, and the ball head rod 13 is slidably matched with an inclined surface 15 set on a wedge block 14, and the wedge block 14 is set on the wall 1.

[0035] Specifically, Figure 1 , Figure 3 , Figure 8 and Fig. 9As shown, two driving arms 12 are located on both sides of the lifting ring 10. When the lifting ring 10 drives the connecting rod 11 to slide upward, the connecting rod 11 drives the driving arm 12 to slide upward. Since the driving arm 12 is provided with a ball head rod 13, on the one hand, the driving arm 12 and the push rod 16 are driven to move upward by the connecting rod 11, and on the other hand, when the ball head rod 13 slides along the wedge block 14, the ball head rod 13 and the push rod 16 are pushed to move horizontally by the inclined surface 15. In addition, the lifting ring 10 and the connecting rod 11 can be detachably installed. The purpose of this is that when the two walls 1 are assembled, the lifting ring 10 can be detached from the wall 1, and the wedge block 14 can also be detached from the wall 1, and then used on other unassembled walls 1, which can save materials. The connection between the wedge block 14 and the wall 1 can be connected by bolts, and the connecting rod 11 and the lifting ring 10 can also be connected by bolts.

[0036] The positioning mechanism also includes four support frames 7, which correspond to four push rods 16 one by one. The support frames 7 are arranged on the wall 1, and a sliding frame 6 is slidably installed on the support frame 7. A reset spring 8 is arranged between the sliding frame 6 and the wall 1, and one end of a positioning rod 9 is fixedly installed on the sliding frame 6, and the other end of the positioning rod 9 is slidably matched with the positioning guide rail 4. A plurality of positioning holes 5 are linearly arranged on the positioning guide rail 4. When the positioning rod 9 is inserted into the positioning hole 5, the positioning of the positioning guide rail 4 is completed.

[0037] Specifically, the support frame 7 is detachably mounted on the wall 1 by bolts. After the assembly of multiple walls 1 is completed, the support frame 7 and the sliding frame 6 can be removed and installed on the unassembled wall 1, which can save materials. In the initial state, the push rod 16 is located below the support frame 7. During the movement of the push rod 16, the push rod 16 will gradually move from the bottom of the support frame 7 to the same height as the support frame 7, and then move to the top of the support frame 7; at the same time, the push rod 16 will also slide horizontally toward the direction close to the support frame 7. During the movement of the push rod 16 toward the support frame 7, the push rod 16 will contact the sliding frame 6 slidably mounted on the support frame 7, and with the horizontal movement of the push rod 16, the push rod 16 will push the sliding frame 6 to slide on the support frame 7. It should be noted that if Fig. 9 As shown, the inclined surface 15 on the wedge block 14 is located on the side away from the lifting ring 10, so the two push rods 16 located on the same side will move in opposite directions.

[0038] The locking mechanism includes a first locking assembly and a second locking assembly. The first locking assembly includes a locking block 17 fixedly mounted on the wall 1 and a clamping rod 20 rotatably mounted on the wall 1; the second locking assembly includes four positioning cylinders 21.

[0039] The locking block 17 is located above the wall 1, and the clamping rod 20 is located below the wall 1. Two symmetrically arranged inclined surfaces 18 are provided on the locking block 17, and a locking groove 19 is provided below the inclined surface 18; a coil spring is provided at the connection between the clamping rod 20 and the wall 1. In the initial state, the clamping rod 20 is in a horizontal state.

[0040] There are two locking blocks 17 and two clamping rods 20 , and the clamping rods 20 are located below the locking blocks 17 , and the locking blocks 17 and the clamping rods 20 correspond one to one.

[0041] like Fig.11 As shown, when the two walls 1 are assembled, the clamping rod 20 installed on the upper wall 1 will move downward with the wall 1, so that the clamping rod 20 on the upper wall 1 will contact the locking block 17 on the lower wall 1, so that the clamping rod 20 will slide relative to the inclined surface 2 18 on the locking block 17, and at the same time, the clamping rod 20 rotates counterclockwise on the wall 1. At this time, the coil spring generates elastic force, and when the clamping rod 20 moves to the position of the locking groove 19, the clamping rod 20 is no longer pushed by the inclined surface 2 18. Under the elastic force of the coil spring, the clamping rod 20 rotates clockwise, and at this time, the end of the clamping rod 20 that does not contact the wall 1 will be stuck in the position of the locking groove 19, thereby completing the locking of the two walls 1.

[0042] The second locking assembly also includes an upper cover plate 28 and a lower cover plate 29, which are respectively fixedly mounted on both sides of the wall 1. Four circular holes 22 are provided on the upper cover plate 28, and four positioning cylinders 21 are fixedly mounted on the lower cover plate 29. The circular holes 22 correspond to the positioning cylinders 21 one by one. When the two walls 1 are assembled, the positioning cylinder 21 on one wall 1 will be inserted into the circular hole 22 on the other wall 1.

[0043] The second locking assembly also includes a plurality of hollow clamps 26 and limiting cylinders 27, which are respectively fixedly mounted on both ends of the vertical steel bars 25. When the two walls 1 are assembled, the hollow clamps 26 located above will be inserted into the vertical steel bars 25, and the hollow clamps 26 will contact the limiting cylinders 27.

[0044] The inner diameter of the hollow clamp 26 is equal to the diameter of the vertical steel bar 25 , and the outer diameter of the limiting cylinder 27 is not less than the outer diameter of the hollow clamp 26 .

[0045] Specifically, Fig.10 and Fig.11As shown, when the two walls 1 are assembled, the vertical steel bar 25 on the upper wall 1 will descend with the wall 1. At this time, the hollow clamp 26 below the vertical steel bar 25 will move downward to the position of the vertical steel bar 25 installed on the lower wall 1. At this time, the hollow clamp 26 will wrap the end of the vertical steel bar 25. At the same time, the hollow clamp 26 will descend to contact with the limiting cylinder 27. At this time, it means that the two walls 1 are assembled. The limiting cylinder 27 supports the hollow clamp 26. At the same time, the hollow clamp 26 is connected to the end of the vertical steel bar 25 to play a stabilizing role.

[0046] A feed hole 23 is provided on the wall body 1 . The wall body 1 is a hollow structure, and the feed hole 23 is communicated with the wall body 1 . The feed hole 23 is used to transport cement into the wall body 1 .

[0047] A plurality of horizontal steel bars 24 are arranged inside the wall 1 . The plurality of horizontal steel bars 24 and the plurality of vertical steel bars 25 are arranged crosswise, and the horizontal steel bars 24 and the vertical steel bars 25 are fixedly mounted on the wall 1 .

[0048] Specifically, hollow clamps 26 and limiting cylinders 27 can be adaptively installed at both ends of the horizontal reinforcement 24, so as to facilitate the assembly of two walls 1 in the horizontal direction. Those skilled in the art can make adaptive choices.

[0049] The implementation principle of the prefabricated assembled wall in the embodiment of the present application is: the staff operates a device with a mobile function, such as a crane, to lift a wall 1 and assemble it to another fixed wall 1. After the assembly is completed, the initially fixed wall 1 is located at the bottom. The specific assembly process is:

[0050] The two connecting parts on the crane, such as the lifting rope, are connected to the two lifting rings 10 on both sides of the wall 1 (in the initial state, the lifting rings 10, the connecting rods 11 and the wedge blocks 14 are all installed with the wall 1), and then the crane drives the wall 1 to move through the lifting rings 10. The moving states of the wall 1 include moving upward and moving toward the installed wall 1 located below.

[0051] The lifting rope pulls the lifting ring 10 upwards, and the lifting ring 10 will slide along the wall 1, that is, the lifting ring 10 moves to the side close to the upper cover plate 28, so that the connecting rod 11 connected to the lifting ring 10 moves upward, and the connecting rod 11 drives the push rod 16 to move upward through the driving arm 12. During the movement of the driving arm 12, the ball head rod 13 on the driving arm 12 will slide along the inclined surface 15 on the wedge block 14, so that the ball head rod 13 drives the driving arm 12 to slide to the side away from the lifting ring 10, that is, the push rod 16 will also slide in the horizontal direction to the side close to the support frame 7 during the upward movement. It should be noted that in order to enable the driving arm 12 to slide smoothly in the horizontal direction along the connecting rod 11 while moving upward, the friction can be reduced by applying lubricating oil at the connection between the driving arm 12 and the connecting rod 11, and the friction can also be reduced by increasing the smoothness of the surface of the connecting rod 11. In addition, if Fig. 9 As shown, the push rod 16 is connected to the connecting seat on the wall 1, the connecting seat is slidably installed on the wall 1, and the connecting seat is a part of the wall 1. In order to reduce friction, lubricating oil can be applied to the connection between the push rod 16 and the connecting seat, and lubricating oil can be applied to the connection between the connecting seat and the wall 1, so as to reduce the friction when the push rod 16 moves.

[0052] When the wall 1 to be assembled moves to the top of the fixed wall 1, the push rod 16 moves from the bottom of the support frame 7 to the same height as the support frame 7. At this time, due to the gravity of the wall 1, the wall 1 will move downward relative to the ring 10, that is, although the lifting rope does not drive the ring 10 to move upward at this time, the wall 1 will also slide downward relative to the ring 10, so the push rod 16 will also slide to the side close to the support frame 7 at this time.

[0053] The push rod 16 that moves horizontally will push the sliding frame 6 that is slidably mounted on the support frame 7, so that each sliding frame 6 will slide to the side away from the lifting ring 10, and the positioning rod 9 that is fixedly connected to the sliding frame 6 will be driven by the sliding frame 6 to move. At this time, the end of the positioning rod 9 that is inserted into the positioning hole 5 will leave the positioning hole 5, so that the positioning guide rail 4 is released from the restriction, and the positioning guide rail 4 on the upper wall 1 will slide downward along the second guide shell 3 and the first guide shell 2 (such as Fig.11), the positioning guide rail 4 will slide from the first guide shell 2 and the second guide shell 3 on the upper wall 1 to the first guide shell 2 and the second guide shell 3 on the lower wall 1. After the positioning guide rail 4 moves to the first guide shell 2 and the second guide shell 3 below, the two walls 1 to be assembled will only have relative movement in the vertical direction (the direction where the upper cover plate 28 and the lower cover plate 29 are located), that is, the positioning of the two walls 1 is completed through the four positioning guide rails 4. Afterwards, as the push rod 16 moves upward, the push rod 16 will leave the sliding frame 6, and the sliding frame 6 will be reset under the elastic force of the reset spring 8, that is, the sliding frame 6 drives the positioning rod 9 to move to the side close to the positioning hole 5, and finally after the two walls 1 are assembled, the positioning rod 9 is inserted into the positioning hole 5.

[0054] In the embodiment of the present application, the multi-stage linkage mechanism is used to better bear and disperse the force, ensure that the wall 1 is stably installed during the hoisting and docking process, and the ball head rod 13 slides on the wedge block 14 to achieve horizontal movement, ensuring that the push rod 16 has an accurate horizontal sliding path during the up and down movement, and is not easy to deviate, so that the installation accuracy of the wall 1 is greatly improved, and it is particularly suitable for wall structures with high installation accuracy requirements. In addition, the lifting ring 10, the connecting rod 11, the ball head rod 13 and other components can be disassembled or adjusted in position. When the operator assembles walls 1 of different types or sizes on site, these components can be flexibly adjusted or replaced to adapt to a variety of wall structures and installation conditions, thereby enhancing the flexibility of assembly. The multi-component design evenly disperses the force of the wall 1 during the hoisting process, so that the force position and direction of the wall 1 are reasonably distributed, thereby reducing the tilt or displacement caused by uneven force, and improving the stability and safety during the installation process.

[0055] It should be noted that after the two walls 1 are assembled, in order to save materials, the positioning guide rail 4 can be removed from the first guide shell 2 and the second guide shell 3. Of course, the first guide shell 2 and the second guide shell 3 can also be removed. This is conceivable and implementable for those skilled in the art. Just as, when installing the upper wall 1, the lower wall 1 is fixed to the ground, and the cement is transported to the inside of the wall 1 through the feed hole 23, which all belong to the prior art. At the same time, the thickness of the sliding frame 6 in the vertical direction is sufficient to support the push rod 16 to move upward while pushing the sliding frame 6, that is, the sliding frame 6 will not be reset prematurely due to the premature departure of the sliding frame 6 and the push rod 16.

[0056] When the positioning guide rail 4 slides from the upper first guide shell 2 and the second guide shell 3 to contact the lower wall 1, the crane transports the wall 1 downward, and the upper wall 1 approaches the lower wall 1, and finally completes the assembly with the lower wall 1. In this process, the lower cover plate 29 on the upper wall 1 approaches the upper cover plate 28 on the lower wall 1, so that the positioning cylinder 21 fixed on the lower cover plate 29 on the upper wall 1 is inserted into the circular hole 22 on the lower wall 1, so that after completing the re-positioning, the connection of the two walls 1 can be completed. At the same time, the card rod 20 rotatably mounted on the upper wall 1 will contact the locking block 17 installed on the lower wall 1, and when the card rod 20 contacts the second inclined surface 18, it will rotate under the drive of the second inclined surface 18, and at the same time, the coil spring will generate elastic force. When the card rod 20 moves to the position below the second inclined surface 18, that is, the locking groove 19, the card rod 20 is no longer pushed, so the elastic force of the coil spring is released, causing the end of the card rod 20 that is not in contact with the wall 1 to produce a reset movement, so that the end of the card rod 20 that is not in contact with the wall 1 will move to the position of the locking groove 19, and the locking groove 19 will be recessed (such as Figure 7 As shown in the figure, the locking groove 19 is used to restrict the clamping rod 20, so that the clamping rod 20 cannot move upward or downward, thereby completing the restriction of the assembled two walls 1. Of course, for those skilled in the art, a stopper can be set below the clamping rod 20, so that even if an upward force is applied to the upper wall 1, the clamping rod 20 cannot rotate due to the existence of the stopper, and the clamping rod 20 will not leave the locking groove 19, thereby ensuring that the two walls 1 will not separate.

[0057] In addition, during the downward movement of the upper wall 1, the hollow clamp 26 on the upper vertical steel bar 25 will move downward to contact the upper end of the vertical steel bar 25 on the lower wall 1, and the hollow clamp 26 will cover the vertical steel bar 25 to complete the docking of the upper and lower vertical steel bars 25. There is a step between the limit cylinder 27 and the vertical steel bar 25, similar to the form of a stepped shaft. The function of the limit cylinder 27 is to prevent the hollow clamp 26 from continuing to move downward, and at the same time, the contact surface between the hollow clamp 26 and the limit cylinder 27 is as sealed as possible to prevent corrosion from air and moisture. At this point, the upper and lower walls 1 have been assembled, and then cement can be transported to the interior of the upper wall 1 through the feed hole 23. Through cement, the horizontal steel bars 24 and the vertical steel bars 25 inside the wall 1 are better fixed, and the purpose of the cross arrangement of the horizontal steel bars 24 and the vertical steel bars 25 is to better provide strength. This is a routine operation, and those skilled in the art can know it.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present invention as above, which are not provided in detail for the sake of simplicity.
