Description

Technical Field

[0001] The present invention relates to the technical field of wall construction, and more specifically, it relates to a prefabricated wall. Background Art

[0002] A prefabricated wall is to move the pre-formed floor slabs to the construction site and move the floor slabs through mobile devices such as cranes to achieve the splicing between the floor slabs, thereby forming a building wall with a certain load-bearing capacity. Compared with the traditional reinforced concrete wall cast on-site, the prefabricated wall has the advantages of short construction period and low construction cost.

[0003] Currently, when installing a prefabricated wall, the prefabricated wall is usually hoisted to the required position, and after aligning two prefabricated walls, they are fixed by tie bolts. However, the existing prefabricated walls are generally heavy and large in volume, making it difficult to accurately install them during hoisting. At the same time, the acting force range of the tie bolts is small, resulting in a weak connection strength at the joint between adjacent two walls, and it is easy to have a certain degree of looseness, leading to unstable connection.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0005] The purpose of the present invention is to provide a prefabricated wall in order to solve the above problems.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A prefabricated wall, including a wall body. A casting cavity is arranged inside the wall body. A plurality of through holes communicating with the casting cavity are arranged at the upper end of the wall body. A lifting nut is detachably connected inside the through holes. A clamping part and a connecting part are arranged on both sides of the wall body. The clamping part and the connecting part are clamped with each other. A plurality of longitudinally distributed first limiting holes are arranged on the clamping part. A plurality of second limiting holes corresponding to the first limiting holes in sequence are arranged on the clamping part. A first limiting mechanism and a second limiting mechanism for limiting the clamping part and the connecting part are arranged between adjacent walls.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 、 Figure 4 and Figure 5As shown in the figure, a prefabricated wall includes a wall 1. A casting cavity 2 is arranged inside the wall 1. A number of criss-crossed reinforcing bars 29 are fixedly connected inside the casting cavity 2. The criss-crossed reinforcing bars 29 can ensure the overall strength of the wall 1. A number of through holes 3 communicating with the casting cavity 2 are arranged at the upper end of the wall 1. A lifting nut 4 is detachably connected inside the through hole 3. When the wall 1 needs to be lifted, the wall 1 is moved and installed through the lifting nut 4. After the wall 1 is installed at the required position, the lifting nut 4 is removed, and then concrete is poured into the casting cavity 2 through the through hole 3 to complete the installation of the wall 1. A steel plate 26 is fixedly installed inside the casting cavity 2. A clamping ring 27 is fixedly connected to the steel plate 26. The clamping ring 27 is located inside the through hole 3. An internal thread 28 is arranged on the inner wall of the clamping ring 27 to realize the threaded fit with the lifting nut 4. The steel plate 26 can ensure the strength of the wall 1 and prevent the clamping ring 27 from detaching from the through hole 3. By arranging the casting cavity 2, the weight of the wall 1 can be reduced, which is convenient for lifting the wall 1.

[0020] Please refer to Figure 1 As shown in the figure, clamping parts 5 and connecting parts 6 are arranged on both sides of the wall 1. When assembling, the clamping parts 5 and the connecting parts 6 of two walls 1 are clamped together. A number of longitudinally distributed first limiting holes 7 are arranged on the clamping part 5. A number of second limiting holes 8 corresponding to the first limiting holes 7 in sequence are arranged on the clamping part 5. A first limiting mechanism and a second limiting mechanism for limiting the clamping part 5 and the connecting part 6 are arranged between adjacent walls 1. The two walls 1 are pre-fixed through the first limiting mechanism, and then the second limiting mechanism is inserted into the first limiting hole 7 and the second limiting hole 8 to further fix the two. By limiting and fixing the wall 1 through the first limiting mechanism and the second limiting mechanism, the contact area between the two walls 1 during fixation is increased, the strength of the connection between the two walls 1 is improved, and the connection is made more stable.

[0021] Please refer to Figure 1 and Figure 2 As shown in the figure, grooves 12 communicating with each other are arranged at the tops of the clamping part 5 and the connecting part 6. Card slots 13 communicating with the grooves 12 are arranged on both sides of the clamping part 5. The first limiting mechanism includes a support plate 14 and clamping plates 15 fixedly connected to both sides of the support plate 14. The support plate 14 is clamped with the groove 12, and the clamping plates 15 are clamped with the card slots 13. When the clamping part 5 and the connecting part 6 are clamped together, the two grooves 12 communicate with each other at this time. The support plate 14 is clamped into the groove 12, and the two clamping plates 15 will be clamped into the card slots 13 at this time, so as to ensure the stability of the connection between the support plate 14 and the groove 12. The first limiting mechanism can play a role in pre-fixing the connection between the clamping part 5 and the connecting part 6.

[0022] Please refer to Figure 1 、 Figure 2 andFigure 3 As shown, the second limiting mechanism includes a first limiting member and a second limiting member. The first limiting member includes a support block 16 and a first cylinder 17. Four clamping blocks 18 distributed in a circumferential array are arranged at one end of the first cylinder 17 far away from the support block 16. There are gaps between adjacent clamping blocks 18. The second limiting member includes a support block 16 and a second cylinder 19. The second cylinder 19 is clamped with the clamping blocks 18. A guiding surface 20 is arranged at one end of the second cylinder 19 far away from the support block 16. A sunk groove 21 for clamping with the support block 16 is arranged on the clamping portion 5. When the first limiting hole 7 and the second limiting hole 8 correspond in sequence, the first limiting member is inserted through the first limiting hole 7 into the second limiting hole 8. At this time, the support block 16 is clamped with the sunk groove 21. At the same time, one person applies force to support the support block 16, and another worker clamps the second limiting member from another direction. The second cylinder 19 will be clamped between the four clamping blocks 18. By applying force to the second limiting member, the second cylinder 19 will squeeze the four clamping blocks 18, causing them to bend outwards, thereby increasing the friction force between the first limiting member, the second limiting member, and the second limiting hole 8, so as to ensure the stability of the installation of the second limiting mechanism and the wall 1. At the same time, through the clamping of the first limiting member and the second limiting member, a limiting effect is exerted on two adjacent walls 1.

[0023] Please refer to Figure 1 and Figure 2 As shown, embedding grooves 9 are arranged on both sides of the wall 1. A support rod 10 is detachably installed in the embedding groove 9. A support seat 11 for clamping with the support rod 10 is arranged on the wall 1. After hoisting the wall 1 to the required position, the support rod 10 is detached from the embedding groove 9 and clamped with the support seat 11. At this time, one end of the support rod 10 abuts against the ground. The support rods 10 located on both sides of the wall 1 can support the wall 1 to prevent the wall 1 from toppling. A support frame 22 for clamping with the support rod 10 is arranged in the embedding groove 9. The support frame 22 plays a role in supporting and limiting the support rod 10. A square groove is arranged on the wall 1. The support seat 11 is located in the square groove. A limiting ring 25 is arranged at one end of the support rod 10. A limiting column 23 fixedly connected with the limiting ring 25 is arranged on the support seat 11. An inclined fixing plate 24 is fixedly connected to one end of the support rod 10. The limiting ring 25 is located on the fixing plate 24. After the support rod 10 is detached, the limiting ring 25 on the fixing plate 24 is sleeved on the limiting column 23. There is an included angle between the inclined fixing plate 24 and the support rod 10. Therefore, after the limiting ring 25 is clamped with the limiting column 23, the support rod 10 will be inclined on both sides of the wall 1, playing a supporting role on both sides to prevent the wall 1 from toppling.

[0024] The wall 1 includes two wall panels, a bottom plate, a top plate and two side plates. The production of the wall 1 includes the following steps: S1: Lay the keel inside the formwork, then fix cross-shaped fasteners at the bottom and both sides of the keel to form a keel framework. Fix the cross-shaped fasteners and the keel with a number of reinforcing ribs 29, and fix the steel plate 26 on the top of the reinforcing ribs 29; S2: Pour concrete into the formwork and let it solidify to form a wall panel; S3: Then turn over the keel framework and pour the bottom plate, top plate and two side plates respectively; S4: Fix the keel to the cross-shaped fastener, invert the wall 1 inside the formwork, and pour the last wall panel; S5: Polish the surface of the wall 1 and hoist it.

[0025] The keel and the cross-shaped fastener are perpendicular to each other. A number of sound insulation boards are laid between the reinforcing ribs 29. After installation, the sound insulation boards can be fixed by pouring concrete into the pouring cavity 2. The sound insulation boards can enhance the sound insulation effect of the wall 1 to a certain extent.
