Abstract
Description
Technical Field
[0001] This application relates to the technical field of building accessories, and in particular to a horizontal connector for the exterior wall of a prefabricated light steel building. Background Art
[0002] Prefabricated light steel buildings adopt a factory production method, and structural components can be manufactured with high precision in the early stage. On-site construction relies on mechanized operations, greatly reducing manual operation errors, improving construction safety and efficiency, and even reaching 4-5 times that of traditional construction methods. The exterior wall of a prefabricated light steel building needs to be fixed to the steel structure skeleton through a horizontal connector.
[0003] However, traditional connectors will penetrate the exterior wall during use. Since the diameter of the through hole opened on the exterior wall is larger than the diameter of the connector, it is easy to cause displacement and shaking of the connector after installation, resulting in poor installation stability. Moreover, the length of most connectors is fixed, making it inconvenient to adjust according to the actual thickness of the exterior wall. When the exterior wall is thick, it cannot be locked and fixed, and when the exterior wall is thin, the connector will have a long protrusion after installation, thus having an adverse impact on subsequent work, resulting in poor flexibility in use. Summary of the Invention
[0004] In order to prevent the connector from shaking after installation, improve the stability of the connector after installation, and at the same time facilitate the fixed connection of exterior walls with different thicknesses.
[0005] A horizontal connector for the exterior wall of a prefabricated light steel building provided by this application adopts the following technical solutions:
[0006] A horizontal connector for the exterior wall of a prefabricated light steel building includes a shaft rod. A resisting structure is provided on the shaft rod, a positioning structure is provided on the shaft rod, a fastening structure is provided on the shaft rod, and a limiting structure is provided on the fastening structure. The positioning structure includes a sliding plate and a connecting rod. The sliding plate is slidably connected to the inside of the shaft rod. Four connecting rods are rotatably connected to the sliding plate. Two resisting rods are slidably connected to the shaft rod. One end of two of the connecting rods is rotatably connected to one side of the sliding plate and the other end is rotatably connected to one of the resisting rods. One end of the other two connecting rods is rotatably connected to the other side of the sliding plate and the other end is rotatably connected to the other resisting rod. The resisting rods are slidably connected to the shaft rod.
[0007] By adopting the above technical solutions, the locking structure can be tightened against the exterior wall. After the locking structure is tightened against the exterior wall, the resisting structure will be tightened against the steel structure skeleton. After the resisting structure is tightened against the steel structure skeleton, the two resisting rods will also be tightened against the exterior wall at the same time, thereby realizing the positioning of the shaft rod and preventing the shaft rod from moving after installation, effectively improving the stability of the exterior wall after installation.
[0008] Optionally, one side of the abutting rod extends to the outside of the shaft rod. The two abutting rods are symmetrically distributed about the middle of the shaft rod, and the cross section of the end of the abutting rod is in a trapezoidal structure.
[0009] By adopting the above technical solution, the positioning of the shaft rod can be realized by the two abutting rods being simultaneously inside the through hole of the outer wall and abutting against the inner wall of the through hole of the outer wall.

Four stoppers are slidably connected to the connecting seat. Four second springs are arranged inside the connecting seat. One end of the second spring is fixedly connected to the connecting seat, and the other end of the second spring is fixedly connected to the adjacent stopper.
[0013] By adopting the above technical solution, when the stoppers are tightly abutted against the steel structure framework, the two abutting rods will be tightly abutted against the outer wall, so as to realize the positioning of the shaft rod and prevent the shaft rod from moving after installation. And when the stoppers are not tightly abutted against the steel structure framework, the two abutting rods can also be tightly abutted against the outer wall under the action of the first spring, so as to realize the preliminary positioning of the shaft rod.
[0014] Optionally, the cross section of the end of the stopper located outside the connecting seat is in a trapezoidal structure, and the four stoppers are circumferentially arranged in an array about the middle of the connecting seat.
[0015] By adopting the above technical solution, when the shaft rod passes through the outer wall, the outer wall abuts against the stoppers and automatically moves towards the inside of the connecting seat. The four stoppers can increase the contact area between it and the steel structure framework, so as to improve the stability of the connecting piece after installation.
[0016] Optionally, the fastening structure includes a sliding rod and a threaded block, the other end of the shaft rod is slidably connected to the sliding rod, a limiting structure is provided on the sliding rod, the outside of the sliding rod is fixedly connected to the threaded block, and the outside of the threaded block is threadedly connected to a stop block.
[0017] By adopting the above technical solution, when the stop block is close to the shaft rod, the limiting structure will limit the sliding rod, so that the sliding rod cannot move. At this time, the adjustment of the sliding rod position is completed. By adjusting the sliding rod position, the total length of the connecting part can be changed, so as to facilitate the fixation of exterior walls of different thicknesses, thereby effectively improving the flexibility of use.
[0018] Optionally, the cross-section of the stop block close to one end of the shaft rod is a circular structure, and the diameter of the cross-section is larger than the diameter of the cross-section of the shaft rod, the cross-section of the stop block away from one end of the shaft rod is a hexagonal structure, and the sliding rod is a quadrangular prism structure.
[0019] By adopting the above technical solution, the stop block can be easily rotated by a wrench, so that the stop block and the outer wall are pressed tightly.

[0021] By adopting the above technical solution, when the slide bar is adjusted to a suitable position, the card block can be engaged with another card slot. At this time, the slide bar will be unable to move further, thereby completing the adjustment of the slide bar position. Therefore, the slide bar position can be quickly adjusted by pulling the pull rod and then moving the slide bar, thereby effectively improving the convenience of operation.

[0023] By adopting the above technical solution, when the slide bar is adjusted to a suitable position, the clamping block can be automatically engaged with another clamping slot under the action of the third spring.
[0024] Optionally, the cross-section of the card block at one end close to the card slot is a trapezoidal structure, the plurality of card slots are linearly and equidistantly distributed, and the cross-section of the end of the pull rod located outside the slide rod is a T-shaped structure.
[0025] By adopting the above technical solution, the position of the sliding rod can be quickly adjusted by clamping the clamping block into the interior of different clamping slots. Moreover, since the cross-section of the clamping block near the clamping slot is trapezoidal in structure, it can play a guiding role when the clamping block is engaged with the clamping slot.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. When the shaft rod passes through the through hole in the outer wall and rotates the abutting block until it abuts tightly against the outer wall, after the abutting block abuts tightly against the outer wall, the four stoppers will abut tightly against the steel structure framework, and at the same time, the two abutting rods will abut tightly against the inner wall of the through hole in the outer wall. At this time, the fixation of the outer wall is achieved, and the movement of the shaft rod after installation can be avoided by the tight abutment between the two abutting rods and the inner wall of the through hole in the outer wall, thereby effectively improving the stability of the outer wall after installation.
[0028] 2. When the shaft rod passes through the through hole in the outer wall, the sliding rod can be pushed towards the shaft rod. The sliding rod will drive the abutting block to move towards the shaft rod. When the abutting block is close to the shaft rod, the limiting structure will limit the sliding rod, so that the sliding rod cannot move. At this time, the adjustment of the position of the sliding rod is completed. By adjusting the position of the sliding rod, the total length of the connecting piece can be changed, so as to facilitate the fixation of outer walls with different thicknesses, thereby effectively improving the flexibility of use.

Detailed implementation mode
[0038] The following further elaborates on this application in conjunction with the attached drawings. Figures 1-7 Make a further detailed description of this application.
[0039] The embodiment of this application discloses a horizontal connector for the exterior wall of a prefabricated light steel building. Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A horizontal connector for the exterior wall of a prefabricated light steel building, including a shaft rod 1, a resisting structure 2 is provided on the shaft rod 1, a positioning structure 3 is provided on the shaft rod 1, a fastening structure 4 is provided on the shaft rod 1, and a limiting structure 5 is provided on the fastening structure 4.
[0040] During the process of the shaft rod 1 passing through the through hole of the exterior wall, the exterior wall can be made to contact four stop blocks 204 and move towards the inside of the connecting seat 202 at the same time, and four second springs 205 contract simultaneously, so that the stop blocks 204 can smoothly pass through the through hole of the exterior wall. When the resisting rod 303 slides, it will drive the slide plate 301 to slide inside the shaft rod 1 through two connecting rods 302, and the slide plate 301 will drive the first slider 201 to move, and the first spring 203 contracts. When the four stop blocks 204 pass through the through holes of the exterior wall and the steel structure skeleton, the two resisting rods 303 will still be in contact with the inner wall of the through hole of the exterior wall, realizing the preliminary positioning of the shaft rod 1.
[0041] Refer to Figure 1 and Figure 2 , the other end of the shaft rod 1 is slidably connected with a slide rod 401, a limiting structure 5 is provided on the slide rod 401, an external threaded block 402 is fixedly connected to the outside of the slide rod 401, and an external resisting block 403 is threadedly connected to the outside of the threaded block 402.
[0042] After the shaft rod 1 passes through the through-hole in the outer wall, it can pull the pull rod 501 so that the two clamping blocks 506 are not engaged with one of the clamping grooves 507. Then, the sliding rod 401 can be pushed towards the shaft rod 1. The sliding rod 401 will drive the abutting block 403 to move towards the shaft rod 1. When the abutting block 403 is relatively close to the shaft rod 1, the two clamping blocks 506 will be engaged with the other clamping groove 507, so that the sliding rod 401 cannot move. At this time, the adjustment of the position of the sliding rod 401 is completed. By adjusting the position of the sliding rod 401, the total length of the connecting piece can be changed.
[0043] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown in FIGS.
[0044] By pulling the pull rod 501, the pull rod 501 will drive the second slider 502 to move, the third spring 503 will contract, the movement of the second slider 502 will drive the two guide grooves 504 to move, and the movement of the two guide grooves 504 will cause the two guide shafts 505 to move at the same time. The movement of the guide shaft 505 will drive the clamping block 506 to move away from one of the clamping grooves 507. When one end of the clamping block 506 is not engaged with one of the clamping grooves 507, the sliding rod 401 can be moved to adjust its position. When the sliding rod 401 is adjusted to the appropriate position, the third spring 503 will extend to engage the clamping block with the other clamping groove 507. At this time, the sliding rod 401 will not be able to move any further, thus completing the adjustment of the position of the sliding rod 401.
[0045] The implementation principle of the horizontal connector for the prefabricated light steel building exterior wall in the embodiments of the present application is as follows: During use, the shaft rod 1 can pass through the exterior wall. The four stoppers 204 will first come into contact with the exterior wall. Since the cross-section at one end of the stopper 204 is trapezoidal, during the process of the shaft rod 1 passing through the through-hole of the exterior wall, the exterior wall can be made to contact the four stoppers 204 and move towards the inside of the connecting seat 202 simultaneously, and the four second springs 205 contract simultaneously, so that the stoppers 204 can smoothly pass through the through-hole of the exterior wall. At the same time, since the distance between the two ends of the two abutting rods 303 is greater than the diameter of the through-hole on the exterior wall, and the cross-section at the end of the abutting rod 303 is trapezoidal, during the process of the abutting rod 303 passing through the through-hole of the exterior wall, the exterior wall will contact the two abutting rods 303 and slide on the shaft rod 1. The sliding of the abutting rod 303 will drive the slide plate 301 to slide inside the shaft rod 1 through the two connecting rods 302. The slide plate 301 will drive the first slider 201 to move, and the first spring 203 contracts. When the four stoppers 204 pass through the through-holes of the exterior wall and the steel structure skeleton, the two abutting rods 303 will still be in contact with the inner wall of the through-hole of the exterior wall, thus realizing the preliminary positioning of the shaft rod 1. When the shaft rod 1 passes through the through-hole of the exterior wall, the pull rod 501 can be pulled. The pull rod 501 will drive the second slider 502 to move, and the third spring 503 contracts. The movement of the second slider 502 will drive the two guide grooves 504 to move. While the two guide grooves 504 are moving, the two guide shafts 505 will move. The movement of the guide shaft 505 will drive the latch 506 to move away from one of the card slots 507. When one end of the latch 506 is not engaged with one of the card slots 507, the slide rod 401 can be moved to adjust its position. When the slide rod 401 is adjusted to the appropriate position, the third spring 503 will extend and the latch 506 will be engaged with the other card slot 507. At this time, the slide rod 401 can no longer move, thus completing the adjustment of the position of the slide rod 401. By adjusting the position of the slide rod 401, the total length of the connector can be changed, so as to facilitate the fixation of exterior walls with different thicknesses, effectively improving the flexibility of use. When the position adjustment of the slide rod 401 is completed, the abutting block 403 can be continuously rotated by a wrench. Since the abutting block 403 is threadedly connected to the threaded block 402, as the abutting block 403 rotates, it will move towards the shaft rod 1. Continuously rotate the abutting block 403 until it is tightly abutted against the exterior wall. When the abutting block 403 is tightly abutted against the exterior wall, the four stoppers 204 will be tightly abutted against the steel structure skeleton, and at the same time, the two abutting rods 303 will be tightly abutted against the inner wall of the through-hole of the exterior wall. At this time, the fixation of the exterior wall is realized. And when the stoppers 204 are tightly abutted against the steel structure skeleton, the two abutting rods 303 will be tightly abutted against the exterior wall, thus realizing the complete positioning of the shaft rod 1, avoiding the movement of the shaft rod 1 after installation, and effectively improving the stability of the exterior wall after installation.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
