An assembled building connection structure facilitating firm installation

Abstract

The present invention discloses an assembled building connection structure convenient for firm installation, including a groove body. Through holes are formed in both the front surface and the rear surface of the groove body. A rod body is rotatably connected inside the through holes. A first knob is welded to one end of the rod body, and a gear is welded to the end of the rod body away from the first knob. Two sliders are symmetrically arranged on both sides of the groove body respectively. One side of the two sliders penetrates one side of the groove body and is welded with a plate body. When connecting the walls of the assembled building, rotate the first knob to drive the rod body to rotate inside the through hole, thereby driving the gear to rotate. When the gear rotates, it drives the plate body to move left and right. After the plate body fixes the wall, the slider slides inside the second chute, and the slider squeezes the limiting spring, so that the two walls approach and fit together, avoiding the waste of resources and the unstable connection of the wall panels caused by the gap between the two walls.

Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a connection structure for prefabricated buildings that is convenient for firm installation. Background Technique

[0002] Prefabricated buildings refer to transferring a large amount of on-site operation work in traditional construction methods to factories. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the construction site, where they are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern timber structures, etc. Because of their standardized design, factory production, assembly construction, information management, and intelligent application, they are representatives of modern industrial production methods. When connecting existing prefabricated building walls, expansion bolts are set to assist in fixing the wall panels, and then the expansion bolts are fixed through strengthening fixing plates. The space between the walls is filled with waterproof and heat-insulating materials. However, there are still the following problems:

[0003] After the wall connection is completed, a large gap is generated between the two walls, and the two walls cannot fit together. Using a large amount of waterproof and heat-insulating materials to fill the gap not only greatly wastes resources but also causes the phenomenon of unstable connection of the wall panels, prone to cracks, thus reducing the connection effect between the walls. For this reason, a connection structure for prefabricated buildings that is convenient for firm installation is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a connection structure for prefabricated buildings that is convenient for firm installation to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A connection structure for prefabricated buildings that is convenient for firm installation, including a groove body. Through holes are provided on both the front surface and the rear surface of the groove body. A rod body is rotatably connected inside the through hole. One end of the rod body is welded with a first knob, and a gear is welded at the end of the rod body away from the first knob. Two sliders are symmetrically arranged on both sides of the groove body respectively. One side of the two sliders penetrates through one side of the groove body and is welded with a plate body. A rack is welded on the side of the plate body close to the through hole. The gear meshes with the rack. Two first fixing plates are symmetrically welded on the lower surface of the groove body. First threaded holes are provided on one side of the two first fixing plates respectively. A threaded rod is threadedly connected inside the first threaded hole. One end of the threaded rod is welded with a bearing, and the outer ring of the bearing is welded with a second fixing plate.

[0006] As a further preference of this technical solution: A second knob is welded at the end of the threaded rod away from the groove body.

[0007] As a further preferable embodiment of this technical solution: Fixing rods are evenly welded to the side of the second fixing plate away from the bearing.

[0008] As a further preferable embodiment of this technical solution: Two limiting rods are symmetrically welded to the side of the second fixing plate close to the bearing, and two limiting grooves are symmetrically formed in the inner side walls of the groove body respectively, and the two limiting rods are both slidably connected to the interiors of the two limiting grooves.

[0009] As a further preferable embodiment of this technical solution: Two first sliding grooves are symmetrically formed in the two sides of the groove body, and sliding plates are slidably connected to the interiors of the two first sliding grooves.

[0010] As a further preferable embodiment of this technical solution: A buffer spring is welded to the side of the sliding plate close to the groove body, and the end of the buffer spring away from the sliding plate is welded to the interiors of the two first sliding grooves.

[0011] As a further preferable embodiment of this technical solution: Two second threaded holes are symmetrically formed in the upper surface of the sliding plate, and fixing screws are threadedly connected to the interiors of the two second threaded holes.

[0012] As a further preferable embodiment of this technical solution: An anti-slip pad is adhered to the side of the plate body away from the groove body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When connecting the walls of a prefabricated building, rotate the first knob to drive the rod body to rotate inside the through hole, thereby driving the gear to rotate. When the gear rotates, it drives the plate body to move left and right. After the plate body fixes the wall, the slider slides inside the second sliding groove, and the slider squeezes the limiting spring, so that the two walls approach and fit together, avoiding the waste of resources and the unstable connection of the wall panels caused by the existence of gaps between the two walls.

[0025] Embodiment

[0026] Please refer to Figure 1-6 , the present invention provides a technical solution: an assembly type building connection structure that is convenient for firm installation, including a tank body 1. Through holes 11 are provided on both the front surface and the rear surface of the tank body 1. A rod body 10 is rotatably connected inside the through holes 11. One end of the rod body 10 is welded with a first knob 5, and the end of the rod body 10 far from the first knob 5 is welded with a gear 16. Two sliders 9 are symmetrically arranged on both sides of the tank body 1 respectively. One side of the two sliders 9 penetrates through one side of the tank body 1 and is welded with a plate body 14. A rack 15 is welded on the side of the plate body 14 close to the through hole 11. The gear 16 and the rack 15 are meshed with each other. Two first fixing plates 6 are symmetrically welded on the lower surface of the tank body 1. First threaded holes 18 are provided on one side of the two first fixing plates 6. A threaded rod 12 is threadedly connected inside the first threaded holes 18. One end of the threaded rod 12 is welded with a bearing 17, and the outer ring of the bearing 17 is welded with a second fixing plate 21.

[0027] In this embodiment, specifically: a second knob 7 is welded to one end of the threaded rod 12 away from the groove body 1; through the setting of the second knob 7, it is convenient for the staff to hold the second knob 7 and rotate to drive the threaded rod 12 to rotate inside the first threaded hole 18, avoiding damage to the staff's hands caused by the threaded rod 12.

[0028] In this embodiment, specifically: fixing rods 22 are evenly welded to the side of the second fixing plate 21 away from the bearing 17; through the setting of the fixing rods 22, when the second fixing plate 21 approaches the wall, the fixing rods 22 are stuck on the surface of the wall, preventing the wall from shaking.

[0029] In this embodiment, specifically: two limiting rods 20 are symmetrically welded to the side of the second fixing plate 21 close to the bearing 17, and two limiting grooves 19 are symmetrically formed on the inner side walls of the groove body 1 respectively, and the two limiting rods 20 are both slidably connected inside the two limiting grooves 19; through the setting of the limiting rods 20 and the limiting grooves 19, when the second fixing plate 21 moves, it drives the limiting rods 20 to slide inside the limiting grooves 19, thereby preventing the second fixing plate 21 from rotating.

[0030] In this embodiment, specifically: two first sliding grooves 4 are symmetrically formed on both sides of the groove body 1, and a sliding plate 2 is slidably connected inside each of the two first sliding grooves 4; through the setting of the first sliding grooves 4 and the sliding plate 2, when the sliding plate 2 slides out of the inside of the first sliding groove 4, the staff can adjust the wall through the sliding plate 2.

[0031] In this embodiment, specifically: a buffer spring 24 is welded to the side of the sliding plate 2 close to the groove body 1, and one end of the buffer spring 24 away from the sliding plate 2 is welded inside the two first sliding grooves 4; through the setting of the buffer spring 24, when the sliding plate 2 slides out of the inside of the first sliding groove 4, the deformation of the buffer spring 24 can drive the sliding plate 2 to slide back into the inside of the first sliding groove 4 again.

[0032] In this embodiment, specifically: two second threaded holes 25 are symmetrically formed on the upper surface of the sliding plate 2, and fixing screws 3 are threadedly connected inside the two second threaded holes 25; through the setting of the second threaded holes 25 and the fixing screws 3, by rotating the fixing screws 3 threadedly connected inside the second threaded holes 25, the sliding plate 2 can be fixed on the upper surface of the wall, thereby fixing the groove body 1 on the wall.

[0033] In this embodiment, specifically: an anti-slip pad 13 is bonded to the side of the plate body 14 away from the groove body 1; through the setting of the anti-slip pad 13, when one side of the plate body 14 is attached to the surface of the wall, the anti-slip pad 13 can increase the friction between the plate body 14 and the wall.

[0034] In this embodiment, specifically: two second sliding grooves 8 are symmetrically formed on both sides of the groove body 1, and two sliding blocks 9 are both slidably connected to the interiors of the two second sliding grooves 8; through the arrangement of the second sliding grooves 8, when the plate body 14 slides, it drives the sliding blocks 9 to slide inside the second sliding grooves 8, and the second sliding grooves 8 limit and guide the sliding blocks 9 and the plate body 14.

[0035] In this embodiment, specifically: limiting springs 23 are welded to the inner side walls of the two second sliding grooves 8, and one end of each limiting spring 23 close to the sliding block 9 is welded to one side of the sliding block 9; through the arrangement of the limiting springs 23, when the sliding blocks 9 slide inside the second sliding grooves 8, they squeeze the limiting springs 23, thereby limiting the sliding blocks 9 and preventing the sliding blocks 9 from colliding with the groove body 1 and causing damage.

[0036] Working principle or structural principle: During use, place the groove body 1 on the upper surfaces of two walls, and one side of the plate body 14 is attached to the surfaces of the two walls. The anti-slip pads 13 increase the friction between the plate body 14 and the two walls. Rotate the first knob 5 to drive the rod body 10 to rotate inside the through hole 11, thereby driving the gear 16 to rotate. The teeth of the gear 16 mesh with the rack 15. When the gear 16 rotates, it drives the plate body 14 to move left and right. The sliding blocks 9 slide inside the second sliding grooves 8, and the sliding blocks 9 squeeze the limiting springs 23. The limiting springs 23 and the second sliding grooves 8 cooperate to limit the sliding blocks 9, causing the two walls to approach and fit together. At the same time, the worker rotates the second knob 7 to drive the threaded rod 12 to rotate inside the first threaded hole 18 and the bearing 17, causing the second fixing plate 21 to approach the two walls. The second fixing plate 21 drives the limiting rod 20 to slide inside the limiting groove 19, thereby limiting the second fixing plate 21 and preventing the second fixing plate 21 from rotating. At the same time, the second fixing plate 21 drives the fixing rod 22 to insert into the interiors of the two walls, thereby fixing the walls. Pull the sliding plate 2 to slide inside the first sliding groove 4 and pull the buffer spring 24. When the sliding plate 2 slides to the upper surfaces of the two walls, rotate the fixing screw 3 threadedly connected inside the second threaded hole 25 to fix the sliding plate 2. At this time, the buffer spring 24 drives the sliding plate 2 to slide inside the first sliding groove 4, causing the two walls to approach each other and preventing a gap from existing between the two walls, which would result in a waste of resources.
