Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated wall installation, and specifically to a vertical keel installation structure for prefabricated walls. Background Technique

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to the factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods. Before installing the prefabricated wall, it is necessary to first install the vertical keel of the wall.

[0003] In the prior art, such as the "Quick Installation Structure of a New Type of Demountable and Reusable Prefabricated Wall" with Chinese Patent Application No. CN109750770A, it includes a top keel, a ground keel, a vertical keel, a side keel, a wall panel and a lock. The bottom end of the top keel is provided with a ground keel, and side keels are connected to both sides between the top keel and the ground keel. The inner cavity of the top keel is inserted with a wall panel, and the outer side of the bottom end of the wall panel is wrapped around the outer wall of the ground keel. A vertical keel is installed between the top keel and the ground keel. A wall panel cushion strip is fixedly padded at the bottom end of the wall panel. A sound-absorbing cotton strip is filled between the vertical keel and the wall panel. Embedded grooves are provided on both inner sides of the vertical keel. The present invention is convenient and fast to install, the wall can be demounted and reused, the wall can be disassembled and the wall position can be changed according to user needs, reducing resource waste. It is a dry prefabricated construction, with fast construction speed and environmental protection. There is no need to caulk and apply putty or make a decorative surface later, reducing dust pollution.

[0004] However, when installing the vertical keel, it is necessary to connect the vertical keel to the ceiling keel and the ground keel respectively.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0036] Please refer to Figure 1-4 , the present invention provides a technical solution: a vertical keel installation structure for an assembled wall, including a vertical keel installation structure for an assembled wall, including a vertical keel 2, a ceiling keel 1 is arranged at the top of the vertical keel 2, a floor keel 3 is arranged at the bottom of the vertical keel 2, a lower connection component 5 is arranged inside the floor keel 3, two limiting mechanisms 4 are arranged above the lower connection component 5, and an upper connection component 6 is arranged inside the ceiling keel 1;

[0037] The limiting mechanism 4 includes a bottom plate 44, a moving plate 42 and a limiting plate 41. Railways 43 are fixedly installed on both side surfaces of the bottom plate 44. A moving plate 42 is arranged above the bottom plate 44. Guide blocks 48 are fixedly connected to both sides of the bottom of the moving plate 42. The guide blocks 48 are slidably installed on the surfaces of the railways 43. The limiting plate 41 is located on one side of the moving plate 42. A number of reinforcing brackets 49 are fixedly installed on one side of the bottom of the moving plate 42. One end of the reinforcing bracket 49 is fixedly connected to the limiting plate 41. Three connecting grooves 411 are formed on the surface of the limiting plate 41. A fixing frame 45 is arranged on one side of the bottom plate 44. A rotating block 47 is arranged on one side of the fixing frame 45. An adjusting rod 46 is fixedly connected to one side of the rotating block 47. One end of the adjusting rod 46 penetrates through the fixing frame 45. One end of the adjusting rod 46 is rotatably connected to the bottom end of the limiting plate 41.

[0038] The working principle of this embodiment is as follows: First, two limiting mechanisms 4 can be respectively arranged on both sides of the top of the mounting block 54. During installation, the fixing frame 45 and the bottom plate 44 can both be connected to the mounting block 54 through bolts. After installation is completed, the rotating block 47 can be driven to drive the adjusting rod 46 to rotate. During the rotation of the adjusting rod 46, the limiting plate 41 can be driven to move together. Since the limiting plate 41 and the moving plate 42 are connected, the limiting plate 41 and the moving plate 42 will move simultaneously. Also, because guide blocks 48 are installed on both sides of the bottom of the moving plate 42, under the limiting effect of the railways 43, the guide blocks 48 can slide along the surfaces of the railways 43, which can ensure that the limiting plate 41 and the moving plate 42 remain stable during movement. Then, bolts are passed through the connecting grooves 411 to be connected to the fixing holes 21, which can facilitate the installation of the limiting plate 41 on both sides of the vertical keel 2 to complete the installation of the vertical keel 2. When the position of the vertical keel 2 needs to be adjusted, the bolts used for connecting the limiting plate 41 and the vertical keel 2 are removed. Then, by turning the rotating block 47, the rotation of an adjusting rod 46 can be adjusted, and the limiting plate 41 on one limiting mechanism 4 can be moved to adjust a movable space in the direction where the vertical keel 2 needs to move. Next, the adjusting rod 46 of the other limiting mechanism 4 is adjusted. During the adjustment process, the handle can be inserted into the insertion interface 471 to facilitate the rotation of the rotating block 47. At this time, when controlling the rotation of the rotating block 47, the adjusting rod 46 connected to it can push the vertical keel 2 to move. Since the movable holes on both sides of the vertical keel 2 are limited by the limiting plate 41 during the adjustment process, it is possible to avoid a large displacement of the vertical keel 2 during adjustment, resulting in the need to rotate the rotating block 47 back. Finally, through the cooperation of the two limiting mechanisms 4, the position of the vertical keel 2 can be quickly and accurately adjusted. Embodiment

[0039] At the same time, according to Figure 4 - Figure 7As shown in the figure, the lower connecting component 5 includes a first fixing plate 51, a connecting frame 52 and a limiting frame 56. The bottom of the first fixing plate 51 is fixedly connected to the floor joist 3. Two connecting frames 52 are symmetrically arranged on the top of the floor joist 3.

The mounting block 54 is located inside the claw slot 53. A mounting groove 541 is arranged on the surface of the mounting block 54. A sliding groove 55 is formed on one side of the connecting frame 52. A limiting frame 56 is fixedly installed on the side wall of the connecting frame 52; The upper connecting component 6 includes a second fixing plate 61 and a support frame 62. One side of the second fixing plate 61 is fixedly connected to the ceiling joist 1. Support frames 62 are arranged on both sides of the second fixing plate 61. Two movable grooves 11 are formed on one side of the ceiling joist 1. A fixing screw 64 is arranged inside the movable groove 11. One end of the fixing screw 64 passes through the movable groove 11, and the fixing screw 64 is connected to the vertical keel 2.

[0040] It is necessary to install the bottom end of the vertical keel 2 on the tops of the two connecting frames 52. However, during the installation, under the limiting effect of the limiting frame 56 on the vertical keel 2, the bottom end of the vertical keel 2 slides along the surface of the limiting frame 56. Then, the vertical keel 2 can be accurately installed on the tops of the two connecting frames 52. During the sliding installation, the convex blocks on both sides of the bottom of the vertical keel 2 will also move inside the sliding groove 55, which can play a guiding role. After the preliminary installation, since the limiting frame 56 can limit the up-and-down movement space of the vertical keel 2;

[0041] Adjust the rotating rod through the rotating block 47, and then control the position of the vertical keel 2 through the current plate. During the movement of the vertical keel 2, the fixing screw 64 can slide inside the limiting groove. The vertical keel 2 can be limited by the limiting groove and the fixing screw 64. After the adjustment process, cover the limiting sleeve 63 on the surface of the fixing screw 64, and then connect the connecting plate 631 to the ceiling joist 1. After that, the two support frames 62 can be placed inside both sides of the vertical keel 2 to support the vertical keel 2. Then, the vertical keel 2 can be connected to the second fixing plate 61 through bolts, and the vertical keel 2 and the support frame 62 can be connected through bolts. Embodiment

[0042] At the same time, according to Figure 1 - Figure 7As shown, a limit sleeve 63 is sleeved on the surface of one end of a fixed screw rod 64. One side of the limit sleeve 63 is fixedly connected with a connecting plate 631, and the connecting plate 631 is fixedly connected with the side wall of the ceiling joist 1; the adjusting rod 46 is threadedly connected to the fixing bracket 45. The fixing bracket 45 is an L-shaped structure. The fixing bracket 45 is connected to the mounting block 54 by bolts. The bottom plate 44 is connected to the mounting block 54 by bolts; one end of the rotating block 47 is provided with an insertion port 471 in an inward groove. The insertion port 471 is in the shape of an internal hexagon; the guide block 48 is slidably connected to the track 43. A number of fixing holes 21 are opened on both sides of one end of the vertical keel 2, and the fixing holes 21 correspond to the connecting grooves 411; both sides of the bottom end of the vertical keel 2 are located above the connecting frame 52. Both sides of the bottom end of the vertical keel 2 are provided with convex blocks, and the convex blocks are located in the sliding grooves 55; both ends of the limit frame 56 penetrate through the bottom end of the vertical keel 2, and the limit frame 56 is movably connected to the vertical keel 2; the cross-section of the support frame 62 is in a concave shape. The two support frames 62 are respectively located inside both sides of the vertical keel 2, and the vertical keel 2 is connected to the support frame 62 by bolts.

[0043] The working principle of the whole device: First, the bottom end of the vertical keel 2 needs to be installed on the tops of the two connecting frames 52. However, during the installation, under the limiting effect of the limit frame 56 on the vertical keel 2, the bottom end of the vertical keel 2 slides along the surface of the limit frame 56. Then, the vertical keel 2 can be accurately installed on the tops of the two connecting frames 52. During the sliding installation, the convex blocks on both sides of the bottom of the vertical keel 2 will also move along the inside of the sliding groove 55, which can play a guiding role. After the preliminary installation, since the limit frame 56 can limit the up and down movement space of the vertical keel 2;

[0044] Next, the two limiting mechanisms 4 can be respectively arranged on both sides of the top of the mounting block 54. The rotating rod is adjusted through the rotating block 47, and then the position of the vertical keel 2 is controlled by the current plate. During the movement of the vertical keel 2, the fixed screw rod 64 can slide inside the limiting groove. The vertical keel 2 can be limited by the limiting groove and the fixed screw rod 64. After the adjustment process, the limit sleeve 63 is sleeved on the surface of the fixed screw rod 64, and then the connecting plate 631 is connected to the ceiling joist 1. After that, the two support frames 62 can be placed inside both sides of the vertical keel 2 to support the vertical keel 2. Then, the vertical keel 2 and the second fixing plate 61 can be connected by bolts, and the vertical keel 2 and the support frame 62 are connected by bolts.
