Description

Technical Field

[0001] This utility model belongs to the field of scaffolding splicing technology, and in particular relates to an auxiliary fixing device for scaffolding splicing. Background Technology

[0002] Frame scaffolding is a highly efficient construction equipment with a frame structure. It consists of standardized steel pipe components connected by pins or bolts to form "gate"-shaped units, allowing for rapid assembly into working platforms of varying heights and spans. Its stable structure and high load-bearing capacity make it widely used in building exterior construction, interior decoration, bridge and tunnel engineering, and temporary construction for large events. Compared to traditional coupler-type scaffolding, frame scaffolding offers advantages such as convenient installation, rapid dismantling, high reusability, and a high safety factor. It is particularly suitable for high-altitude, multi-faceted operations, effectively improving construction efficiency and reducing labor costs.

[0003] The problem with existing technology is that when scaffolding is spliced, the uprights of the top gantry are usually inserted vertically into the uprights of the bottom gantry. After the two gantry are inserted, the tie rods supporting the gantry are connected. After the tie rods are installed, connecting rods are inserted at the junction of the uprights of the two gantry layers and fixed with locking pins to secure the gantry. However, there is no function to assist in fixing the gantry when it is inserted. During the installation of tie rods, the two gantry are prone to swaying, which requires the operators to manually straighten the gantry, which is time-consuming and laborious, thus affecting the efficiency of the installation. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an auxiliary fixing device for scaffolding splicing. It has the advantage of conveniently assisting in fixing the scaffolding during splicing, solving the problem that existing scaffolding splicing typically requires vertically inserting the uprights of the top scaffolding into the uprights of the bottom scaffolding. After the two scaffoldings are inserted, the tie rods supporting the scaffolding are connected. After the tie rods are installed, connecting rods are inserted at the junction of the uprights of the two scaffoldings and secured with locking pins. However, the existing scaffolding lacks an auxiliary fixing function during insertion, and the two scaffoldings are prone to swaying during tie rod installation, requiring operators to manually straighten the scaffolding, which is time-consuming and labor-intensive, thus affecting installation efficiency.

[0005] This utility model is implemented as follows: an auxiliary fixing device for scaffold splicing includes two frames and a bearing plate. Positioning plates are fixedly connected to the front and rear sides of the bottom of the frames. Fixing shells are fitted onto the front and rear surfaces of the top of the frames. Support plates are fixedly connected to the front and rear sides of the curved surfaces of the fixing shells. Fixing grooves are formed on the front and rear sides of the curved surfaces of the positioning plates. Fixing devices that cooperate with the fixing grooves are provided on the inner side of the support plates. A control device that cooperates with the fixing devices is provided in the inner cavity of the fixing shells.

[0006] As a preferred embodiment of this utility model, the bottom of the positioning plate is provided with a plurality of positioning holes, which are evenly distributed on the bottom of the positioning plate, and the top of the fixed housing is fixedly connected with a plurality of positioning posts, the positions of which correspond to the positioning holes.

[0007] As a preferred embodiment of this utility model, the fixed housing is fixedly connected to the gantry, and the curved surface of the fixed housing is provided with a limiting hole for use with the control device.

[0008] As a preferred embodiment of this utility model, the fixing device includes two support columns, a locking block is sleeved on the surface of the support columns, springs are provided on the left and right sides of the front side of the locking block, a push plate is provided at the bottom of the locking block, and a push column is provided at the bottom of the push plate.

[0009] As a preferred embodiment of the present invention, the control device includes a control board, with arc-shaped holes on both sides of the top surface of the control board, and a toggle plate provided on one side of the curved surface of the control board.

[0010] In a preferred embodiment of this invention, the front and rear sides of the support column are fixedly connected to the inner side of the support plate. The spring is sleeved on the surface of the support column, and its front and rear sides are fixedly connected to the inner side of the support plate and the locking block, respectively. The side of the push plate closest to the locking block is fixedly connected to the locking block. The side of the push plate furthest from the locking block penetrates the fixed housing and extends into the inner cavity of the fixed housing, where it is fixedly connected to the push column. The bottom of the push column passes through the arc-shaped hole and extends into the inner cavity of the arc-shaped hole, contacting the inner wall of the arc-shaped hole.

[0011] In a preferred embodiment of this invention, the control plate is sleeved on the inner surface of the fixed housing, the actuating plate is fixedly connected to the control plate on the side near the control plate, and the actuating plate on the side away from the control plate passes through the limiting hole and extends to the outside of the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem of existing scaffolding systems, which, through the combined use of a positioning plate, a fixed housing, a support plate, a fixing groove, a fixing device, and a control device, typically require vertically inserting the uprights of the top scaffold into the uprights of the bottom scaffold during splicing. After the two scaffolds are inserted, the tie rods supporting the scaffolds are connected. After the tie rods are installed, connecting rods are inserted at the junction of the uprights of the two scaffolds and fixed with locking pins to secure the scaffold. However, the scaffold lacks auxiliary fixing function when inserting the scaffold, and the two scaffolds are prone to shaking during the installation of the tie rods, requiring operators to manually straighten the scaffold, which is time-consuming and laborious, thus affecting the efficiency of the installation.

[0014] 2. By setting positioning columns and positioning holes, this utility model can limit the position of the top layer of scaffolding when splicing scaffolding.

[0015] 3. This utility model can protect the control device by setting a fixed housing, and can limit the movement of the toggle plate by setting a limiting hole.

[0018] 6. This utility model supports the spring and the locking block by setting a support rod. It fixes the positioning plate by setting the locking block and the fixing groove, thereby assisting in fixing the top gantry.

Detailed Implementation

[0026] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown in the figure, an auxiliary fixing device for scaffold splicing provided in this utility model embodiment includes two frames 1 and a bearing plate 2. Positioning plates 3 are fixedly connected to the front and rear sides of the bottom of the frames 1. Fixing shells 4 are fitted on the front and rear surfaces of the top of the frames 1. Support plates 5 are fixedly connected to the front and rear sides of the curved surface of the fixing shells 4. Fixing grooves 6 are opened on the front and rear sides of the curved surface of the positioning plates 3. Fixing devices 7 that cooperate with fixing grooves 6 are provided on the inner side of the support plates 5. Control devices 8 that cooperate with fixing devices 7 are provided in the inner cavity of the fixing shells 4.

[0029] refer to Figure 2 and Figure 3 The bottom of the positioning plate 3 has multiple positioning holes 9, which are evenly distributed on the bottom of the positioning plate 3. The top of the fixed housing 4 is fixedly connected with multiple positioning posts 10, and the positions of the positioning posts 10 correspond to the positioning holes 9.

[0030] By adopting the above solution, positioning columns 10 and positioning holes 9 can be set to limit the top layer of scaffolding during scaffolding splicing.

[0031] refer to Figure 2 and Figure 3The fixed housing 4 is fixedly connected to the gantry 1, and the curved surface of the fixed housing 4 is provided with a limiting hole 11 for use with the control device 8.

[0032] The above solution is adopted: by setting a fixed housing 4, the control device 8 can be protected, and by setting a limiting hole 11, the toggle plate 803 can be limited.

[0033] refer to Figure 4 The fixing device 7 includes two support columns 701. A locking block 702 is sleeved on the surface of the support column 701. Springs 703 are provided on the left and right sides of the front side of the locking block 702. A push plate 704 is provided at the bottom of the locking block 702. A push column 705 is provided at the bottom of the push plate 704.

[0034] The above solution allows for auxiliary fixation of the gantry 1 during scaffolding assembly by setting up the fixing device 7, facilitating the subsequent installation of the tie rods.

[0035] refer to Figure 4 The control device 8 includes a control plate 801. Arc-shaped holes 802 are provided on both sides of the top surface of the control plate 801, and a toggle plate 803 is provided on one side of the curved surface of the control plate 801.

[0036] The above solution is adopted: by setting up the control device 8, the fixing device 7 can be controlled, which facilitates the subsequent disassembly of the top-level gantry 1.

[0037] refer to Figure 3 and Figure 4 The front and rear sides of the support column 701 are fixedly connected to the inner side of the support plate 5. The spring 703 is sleeved on the surface of the support column 701, and its front and rear sides are fixedly connected to the inner side of the support plate 5 and the locking block 702, respectively. The side of the push plate 704 close to the locking block 702 is fixedly connected to the locking block 702. The side of the push plate 704 away from the locking block 702 passes through the fixed housing 4 and extends into the inner cavity of the fixed housing 4 to be fixedly connected to the push column 705. The bottom of the push column 705 passes through the arc-shaped hole 802 and extends into the inner cavity of the arc-shaped hole 802 to contact the inner wall of the arc-shaped hole 802.

[0038] The above solution is as follows: by setting a support rod, the spring 703 and the locking block 702 can be supported; by setting the locking block 702 and the fixing groove 6, the positioning plate 3 can be fixed, thereby providing auxiliary fixation for the top gantry 1; by setting the spring 703, the rebound force released after compression can push the locking block 702 to move in the opposite direction and reset, so that the top gantry 1 is fixed after insertion; by setting the push plate 704, the locking block 702 can be moved; and by setting the push column 705, the push plate 704 can be moved.

[0039] refer to Figure 3 and Figure 4 The control plate 801 is sleeved on the inner surface of the fixed housing 4. The side of the toggle plate 803 close to the control plate 801 is fixedly connected to the control plate 801. The side of the toggle plate 803 away from the control plate 801 passes through the limiting hole 11 and extends to the outside of the limiting hole 11.

[0040] The above solution is adopted as follows: By setting up a control plate 801 and an arc-shaped hole 802, the arc-shaped hole 802 can be used to squeeze and push the column 705 during the rotation of the control plate 801, and push the column 705 to move, thereby causing the locking block 702 to disengage from the inner cavity of the fixing groove 6, which facilitates the operator to disassemble the top gantry 1. By setting up a toggle plate 803, the control plate 801 can be rotated by toggling the toggle plate 803, causing the locking block 702 to disengage from the inner cavity of the fixing groove 6.

[0041] The working principle of this utility model:

[0042] When it is necessary to assemble the gantry 1, place the gantry 1 to be assembled at a suitable position on top of the bottom gantry 1, so that the positioning hole 9 on the surface of the bottom positioning plate 3 of the gantry 1 to be assembled corresponds to the position of the positioning post 10 on the top of the top fixing housing 4 of the bottom gantry 1. Then, place the gantry 1 to be assembled downwards, so that the bottom of the gantry 1 to be assembled fits over the top of the bottom gantry 1. When placing the gantry 1 to be assembled, the positioning post 10 will pass through the positioning hole 9 and extend to the positioning hole 9. The inner cavity limits the position of the gantry 1 to be spliced. Simultaneously, the positioning plate 3 at the bottom of the support to be spliced, as it descends with the gantry 1, comes into contact with the inclined surface of the locking block 702, generating pressure. This pressure pushes the locking block 702 to move on the surface of the support column 701, compressing the spring 703. The locking block 702 then drives the push plate 704 to move synchronously, which in turn drives the push column 705 to move linearly within the inner cavity of the arc-shaped hole 802. As the push column 705 moves linearly within the arc-shaped hole 802, it drives the control plate 801 to rotate. The control plate 801 then drives the actuating plate 803 to rotate. When the positioning plate 3 reaches the appropriate position, the position of the fixing groove 6 on the surface of the positioning plate 3 corresponds to the position of the locking block 702. At this time, the locking block 702 is no longer squeezed. Simultaneously, the rebound force released after the spring 703 is squeezed will push the locking block 702 to move in the opposite direction, allowing the locking block 702 to re-enter the inner cavity of the fixing groove 6 to fix the gantry 1 that needs to be spliced. At the same time, during the reverse movement of the locking block 702, it will drive the push plate 704 to move synchronously in the opposite direction. The push plate 704 will drive the push column 705 to move in the opposite direction within the arc-shaped hole 802. During the reverse movement of the push column 705 within the arc-shaped hole 802, it will drive the control plate 801 to rotate in the opposite direction. The control plate 801 will then drive the actuating plate 803 to rotate in the opposite direction and reset, completing the fixing.

[0043] In summary, this auxiliary fixing device for scaffolding splicing, through the coordinated use of positioning plate 3, fixing shell 4, support plate 5, fixing groove 6, fixing device 7, and control device 8, solves the problem of existing scaffolding splicing methods. These methods typically require vertically inserting the uprights of the top scaffolding into the uprights of the bottom scaffolding, connecting the tie rods of the supporting scaffolding after the insertion of the two side scaffoldings, and then inserting connecting rods at the junction of the uprights of the two scaffoldings and securing them with locking pins. However, these methods lack auxiliary fixing functions during scaffolding insertion, and the two side scaffoldings are prone to swaying during tie rod installation, requiring operators to manually straighten the scaffolding, which is time-consuming and labor-intensive, thus affecting installation efficiency.
