Description

Technical Field

[0001] This utility model relates to the field of scissor bracing technology, and more specifically to a scissor bracing for the exterior facade of a steel pipe scaffold. Background Technology

[0002] Scaffolding is frequently used in civil engineering construction. The scissor bracing on the exterior of the scaffolding is an oblique support on the scaffolding, similar to the X-shaped bars of scissors. Its main function is to enhance the lateral stability of the scaffolding, ensure that the overall structure of the scaffolding does not deform, and prevent the scaffolding from deforming during construction, thus ensuring construction safety. Most existing scissor bracing is fixed to the scaffolding by knob couplers.

[0003] Existing scissor bracing often involves fixing steel pipes in a crisscross pattern, then securing the pipes to the scaffolding uprights using knob couplers. However, the crisscrossing pipes are stacked, with the outermost pipes being farther from the scaffolding than the innermost pipes. Most knob couplers are fixed in size and cannot be adjusted based on the distance of the outermost pipes. This forces the outermost pipes to bend and deform to get closer to the uprights and secure them, generating significant stress that affects structural stability and can even lead to breakage. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a steel pipe scaffold facade scissor brace to solve the problem that most of the knob fasteners in the background art have fixed dimensions and cannot be adjusted according to the distance between the outer steel pipe and the scaffold.

[0005] This utility model provides the following technical solution: a steel pipe scaffold facade scissor bracing, including scaffolding and knob couplers, and also including four steel pipes, the four steel pipes are arranged in two groups of two, the two steel pipes in each group are connected by knob couplers and arranged in parallel, the two groups of steel pipes are arranged crosswise on the facade of the scaffolding, and all four steel pipes are connected to the scaffolding by several knob couplers. The knob couplers include two sets of fixing components and adjusting components, the distance between the two sets of fixing components can be adjusted by adjusting the adjusting components.

[0006] Furthermore, the adjustment assembly includes a fixed tube, a lead screw, a fixed block, a connecting tube, and two first arc-shaped blocks. One end of the fixed tube is closed, and the closed end of the fixed tube is rotatably connected to one of the two first arc-shaped blocks. The lead screw is disposed inside the fixed tube, and one end of the lead screw is fixedly connected to the closed end of the fixed tube. The fixed block is sleeved on the lead screw and threadedly connected to the lead screw. One end of the connecting tube is fixedly connected to the fixed block, and the other end is rotatably connected to the other first arc-shaped block. The other end of the lead screw is located inside the connecting tube.

[0007] Furthermore, both sets of fixing components include a second arc-shaped block, a slot, a rotating rod, a threaded rod, a rectangular groove, a washer, and a nut. One side of each of the two second arc-shaped blocks is rotatably connected to one side of the corresponding first arc-shaped block. The slot is opened on the other side of the first arc-shaped block, and the rectangular groove is opened on the other side of the second arc-shaped block. Both ends of the rotating rod are rotatably connected to the inner wall of the slot. One end of the threaded rod is fixedly connected to the rotating rod. A washer and a nut are fitted on the threaded rod. The washer does not contact the threaded rod, and the nut is located above the washer and is threadedly connected to the threaded rod.

[0008] Furthermore, a baffle is fixedly installed at the other end of the lead screw.

[0009] Furthermore, a support rod is fixedly installed on the fixed pipe.

[0010] Furthermore, a fixing rod is fixedly installed on the connecting pipe.

[0011] The technical effects and advantages of this utility model are as follows: 1. In this utility model, a worker fixes one of the two sets of fixing components to the scaffold. The worker fixes the fixing pipe with one hand and rotates the connecting pipe forward with the other hand. The connecting pipe drives the fixing block to rotate along the thread of the screw rod. This causes the fixing block to move the connecting pipe and the first arc-shaped block that is not fixed to the scaffold away from the first arc-shaped block that is fixed to the scaffold. The distance between the two steel pipes of the outer set and the scaffold can be adjusted, thereby preventing the two steel pipes of the outer set from bending and breaking.

[0014] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 5 The present invention will be further described below. The present invention discloses a steel pipe scaffold facade scissor bracing, including a scaffold 1 and a knob coupler 2, and four steel pipes 3. The four steel pipes 3 are arranged in pairs, forming two groups. The two steel pipes 3 in each group are connected by the knob coupler 2 and arranged parallel to each other. The two groups of steel pipes 3 are arranged crosswise on the facade of the scaffold 1. Each of the four steel pipes 3 is connected to the scaffold 1 by several knob couplers 2. The knob coupler 2 includes two sets of fixing components 201 and an adjusting component 202. The distance between the two sets of fixing components 201 can be adjusted by the adjusting component 202.

[0016] In this implementation plan, during work, the workers connect the two steel pipes 3 of each group using knob couplers 2 and set them parallel to each other. The two groups of steel pipes 3 are arranged crosswise on the outer facade of the scaffold 1. All four steel pipes 3 are connected to the scaffold 1 using several knob couplers 2. The four steel pipes 3 and the scaffold 1 built on the steel pipes 3 are of the same specification. The distance between the two steel pipes 3 of the outer group and the scaffold 1 is greater than the distance between the two steel pipes 3 of the inner group and the scaffold 1. When the workers fix the two steel pipes 3 of the inner group to the scaffold 1, the knob couplers 2 do not need to be adjusted. When the workers fix the two steel pipes 3 of the outer group to the scaffold 1, the knob couplers 2 do not need to be adjusted. When installing a set of two steel pipes 3 onto scaffold 1, the installers should adjust the distance between the two sets of fixing components 201. The workers will fix one set of fixing components 201 to the steel pipe 3 on scaffold 1. By adjusting component 202, the fixing component 201 that is not fixed to scaffold 1 will be moved away from the fixing component 201 that is fixed to scaffold 1. When the distance is adjusted, the other set of fixing components 201 will be used to fix the outer set of two steel pipes 3. This can be adjusted according to the distance from the steel pipe 3 to scaffold 1 to prevent the outer set of two steel pipes 3 from bending and breaking.

[0017] Specifically, the adjustment assembly 202 includes a fixed tube 2021, a lead screw 2022, a fixed block 2023, a connecting tube 2024, and two first arc-shaped blocks 2025. One end of the fixed tube 2021 is closed, and the closed end of the fixed tube 2021 is rotatably connected to one of the two first arc-shaped blocks 2025. The lead screw 2022 is disposed inside the fixed tube 2021, and one end of the lead screw 2022 is fixedly connected to the closed end of the fixed tube 2021. The fixed block 2023 is sleeved on the lead screw 2022 and threadedly connected to the lead screw 2022. One end of the connecting tube 2024 is fixedly connected to the fixed block 2023, and the other end is rotatably connected to the other first arc-shaped block 2025. The other end of the lead screw 2022 is located inside the connecting tube 2024.

[0018] In this implementation scheme, when the two outer steel pipes 3 are connected to the scaffold 1, the worker fixes one end of the two sets of fixing components 201 to the scaffold 1. At this time, the worker fixes the fixing pipe 2021 with one hand and rotates the connecting pipe 2024 with the other hand. The connecting pipe 2024 drives the fixing block 2023 to rotate along the thread of the screw rod 2022. The worker rotates the connecting pipe 2024 in the forward direction, so that the fixing block 2023 drives the connecting pipe 2024 and the first arc-shaped block 2025 that is not fixed to the scaffold 1 away from each other. The first arc-shaped block 2025 is fixed to the scaffold 1; the worker rotates the connecting pipe 2024 in the opposite direction, so that the fixing block 2023 drives the connecting pipe 2024 and the first arc-shaped block 2025 that is not fixed to the scaffold 1 to approach the first arc-shaped block 2025 that is fixed to the scaffold 1, so as to adjust according to the required distance between the two outer steel pipes 3 and the scaffold 1. At this time, the worker fixes the two outer steel pipes 3 through another set of fixing components 201, so that the two outer steel pipes 3 are tightly attached to the two inner steel pipes 3.

[0019] Specifically, both sets of fixing components 201 include a second arc-shaped block 2011, a slot 2012, a rotating rod 2013, a threaded rod 2014, a rectangular groove 2015, a washer 2016, and a nut 2017. One side of each of the two second arc-shaped blocks 2011 is rotatably connected to one side of the corresponding first arc-shaped block 2025. The slot 2012 is opened on the other side of the first arc-shaped block 2025, and the rectangular groove 2015 is opened on the other side of the second arc-shaped block 2011. Both ends of the rotating rod 2013 are rotatably connected to the inner wall of the slot 2012. One end of the threaded rod 2014 is fixedly connected to the rotating rod 2013. A washer 2016 and a nut 2017 are fitted on the threaded rod 2014. The washer 2016 does not contact the lead screw 2022. The nut 2017 is located above the washer 2016 and is threadedly connected to the threaded rod 2014.

[0020] In this embodiment, when the scaffold 1 needs to be fixed by the fixing component 201, the worker places the inner arc surface of the first arc plate against the steel pipe 3 on the support frame. The worker then rotates the corresponding second arc plate, causing its inner arc surface to contact the steel pipe 3 of the scaffold 1. This contact occurs through the first arc block 2025 and the second arc block 2011, wrapping around the steel pipe 3 on the scaffold 1. The worker then rotates the threaded rod 2014, causing the threaded rod 2014 to rotate the washer 2016, nut 2017, and rotating rod 2013, allowing the threaded rod 2014 to rotate into the rectangular groove 2015. At this point, the washer 2016 and nut 2017 are positioned above the second arc block 2011, with the washer 2016 contacting the top of the second arc block 2011. The worker then rotates the nut 2017 in the forward direction. Nut 2017 rotates along threaded rod 2014 and gradually moves towards washer 2016 until nut 2017 contacts and presses against washer 2016. At this time, the first arc plate and the second arc plate are fixed on scaffold 1. After adjusting the distance between the two sets of fixing components 201 by adjusting component 202, the worker fixes another set of first arc plate and second arc plate to the two outer steel pipes 3. When dismantling is required, the worker rotates nut 2017 in the opposite direction so that nut 2017 no longer presses against washer 2016. At this time, the worker rotates threaded rod 2014 in the opposite direction so that threaded rod 2014 comes out from rectangular groove 2015 and drives rotating rod 2013, washer 2016 and nut 2017 to rotate synchronously. At this time, first arc plate and second arc plate no longer clamp and fix steel pipe 3.

[0021] The connection method is the same for the two steel pipes 3 in each group, the connection between the two steel pipes 3 in the inner group and the steel pipes 3 in the scaffold 1, and the connection between the two steel pipes 3 in the outer group and the scaffold 1.

[0022] Specifically, a baffle 4 is fixedly installed at the other end of the lead screw 2022.

[0023] In this embodiment, the baffle 4 prevents the fixing block 2023 from disengaging from the lead screw 2022.

[0024] Specifically, a support rod 5 is fixedly installed on the fixed pipe 2021.

[0025] In this implementation plan, the support rod 5 makes it easier for staff to fix the fixing pipe 2021.

[0026] Specifically, a fixing rod 6 is fixedly installed on the connecting pipe 2024.

[0027] In this implementation plan, the fixing rod 6 makes it easier for workers to rotate the connecting pipe 2024.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
