Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a cantilevered support structure for edge protection of disc-lock scaffolding and its construction method. Background Technology

[0002] After the scaffolding is erected, a working surface will be formed on top of the scaffolding. The edges of the working surface need to be protected. There are usually three traditional erection methods:

[0003] 1. Extend a horizontal bar near the top of the scaffold below the working surface. Fix the horizontal bar and the protective uprights with fasteners. Then connect the protective uprights with horizontal bars to form a whole to form edge protection.

[0004] 2. Secure the protective uprights directly to the horizontal bars near the top of the scaffolding below the working surface using fasteners, and then connect the uprights with horizontal bars to form an edge protection. However, in this case, the edge protection will be somewhat tilted and not vertical.

[0005] 3. If the full-span scaffolding is erected using a disc-lock scaffold, horizontal and diagonal braces are added to the outside to form a triangular support before erecting uprights and horizontal braces to form edge protection. Since the length of the disc-lock scaffold components is generally a fixed value, the distance between the edge of the working surface and the edge protection may be too large, causing some safety hazards. In addition, it increases the amount of erection work, increases labor costs, and extends the construction period.

[0006] Therefore, whether the temporary protective structure is convenient and can improve construction efficiency, and whether the distance between the temporary protective structure and the working surface is appropriate and safe and reliable, are particularly important.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, a cantilevered support structure for edge protection of disc-lock scaffolding and its construction method are provided to solve the problem of large construction workload in the existing method of constructing edge protection at the top of disc-lock full-span scaffolding.

[0009] To achieve the above objectives, a cantilevered support structure for edge protection of disc-lock scaffolding is provided, comprising:

[0010] The connector includes a sleeve movably fitted onto the upper end of the upright of a disc-lock scaffold, two racks, and a clamping assembly. The two racks are connected to opposite sides of the upper end of the sleeve, and the clamping assembly clamps the outer side of the middle portion of the two racks so that the two racks press against opposite sides of the upright.

[0011] The tube assembly includes a movable insert plate and a first tube clamp. The first tube clamp is located on the outer side of the upper end of the two racks. The movable insert plate is located above the first tube clamp and is movably sleeved on the outer side of the upper end of the two racks. The first tube clamp is connected to the movable insert plate by a support rod.

[0012] An outer vertical tube for inserting into the guardrail vertical tube for edge protection is set on the outer side of the upper end of the upright. The outer vertical tube is provided with a fixed insert plate, and the fixed insert plate is connected to the movable insert plate through a cantilever rod.

[0013] The second pipe clamp is fitted onto the outside of the pipe sleeve;

[0014] The diagonal brace has its upper end detachably connected to the lower end of the outer riser, and its lower end detachably connected to the second pipe clamp. A vertically arranged locking rod connects the diagonal brace and the cantilever rod.

[0015] Furthermore, the clamping assembly includes:

[0016] Support beam;

[0017] Two clamping teeth, each having an opposing root and a head, the roots of which are respectively flipped and mounted at both ends of the support beam;

[0018] The drive rod, which drives the two clamping teeth to flip in opposite directions so that the heads of the two clamping teeth are respectively inserted between two adjacent teeth of the two racks, is mounted on the support beam.

[0019] Furthermore, two compensation pads are provided on the inner side of the first pipe clamp. The compensation pads are attached to the outer side of the upper end of the rack. The side of the compensation pad facing the rack has a first tooth pattern, which engages with the rack.

[0020] Furthermore, the movable insert plate has a perforation, and the two opposite walls of the perforation have notches, with the two racks housed in the two notches.

[0021] Furthermore, the inner wall of the notch is formed with a second tooth pattern, which engages with the rack.

[0022] Furthermore, the upper end of the locking rod is fixedly connected to the cantilever rod, and the opposite sides of the lower end of the locking rod are respectively connected to the diagonal brace through hinges.

[0023] This invention provides a construction method for an edge protection cantilever support structure of a disc-lock scaffold, comprising the following steps:

[0024] The connector sleeve is movably fitted onto the upper end of the upright of the disc-lock scaffold;

[0025] The clamping assembly of the connector is clamped to the outer side of the middle of the two racks so that the two racks press against the opposite sides of the upright of the disc-lock scaffold, thereby locking the upright;

[0026] The second pipe clamp is fitted onto the outside of the pipe sleeve;

[0027] The first pipe clamp of the auxiliary pipe assembly is clamped on the outer side of the upper end of the two racks, and the movable insert plate of the auxiliary pipe assembly is set above the first pipe clamp and movably sleeved on the outer side of the upper end of the two racks.

[0028] An external riser is installed on the outer side of the upper end of the upright, and is connected to the fixed insert plate and the movable insert plate of the external riser by a cantilever rod;

[0029] The upper end of the diagonal brace is detachably connected to the lower end of the outer riser, and the lower end of the diagonal brace is detachably connected to the second pipe clamp.

[0032] The beneficial effects of this invention are as follows: the cantilevered support structure for edge protection of the disc-lock scaffolding of this invention, while meeting the requirements of convenient construction and reliable safety, achieves high efficiency in the temporary erection of edge protection for full-span scaffolding. It allows for controllable cantilevered support erection height, avoids cumbersome workload, saves construction costs, and improves the overall construction efficiency of the site. It also solves many problems such as non-standard verticality of edge protection erection for full-span scaffolding and safety hazards caused by excessive distance between the edge protection and the working surface. Simultaneously, this support structure allows for reuse, fully complying with the current requirements of green construction and green building, effectively solving related problems while significantly increasing the utilization rate of related materials and significantly reducing costs. Furthermore, due to the simple material structure and substitutability, all materials in this invention can be replaced by other qualified materials. Attached Figure Description

[0040] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Reference Figures 1 to 6 As shown, the present invention provides an edge protection cantilever support structure for disc-lock scaffolding, including: a connector 1, an auxiliary pipe assembly 2, an outer vertical pipe 3, a second pipe clamp 4, and a diagonal brace 5.

[0043] The connector 1 includes a sleeve 11, two racks 12 and a clamping assembly 13.

[0044] The sleeve 11 is movably fitted onto the upper end of the upright 7 of the disc-lock scaffold.

[0045] There are two racks 12. The two racks 12 are connected to opposite sides of the upper end of the sleeve 11.

[0046] The clamping assembly 13 clamps the outer side of the middle of the two racks 12 so that the two racks 12 press against the opposite sides of the upright.

[0047] The auxiliary pipe assembly 2 includes a movable insert plate 21, a first pipe clamp 22, and a support rod 23.

[0048] The first pipe clamp 22 is clamped to the outer side of the upper ends of the two racks 12. The movable insert plate 21 is located above the first pipe clamp 22. The movable insert plate 21 is movably fitted onto the outer side of the upper ends of the two racks 12. The first pipe clamp 22 is connected to the movable insert plate 21 via a support rod 23.

[0049] The outer riser 3 is located on the outer side of the upper end of the upright. A fixed insert plate 31 is provided on the outer riser 3. The fixed insert plate 31 is connected to the movable insert plate 21 via a cantilever rod 32. The outer riser 3 is used for the insertion of the guardrail riser 6 for edge protection.

[0050] The second pipe clamp 4 is located on the outside of the pipe sleeve 11.

[0051] The diagonal brace 5 is inclined. The upper end of the diagonal brace 5 is detachably connected to the lower end of the outer riser 3. The lower end of the diagonal brace 5 is detachably connected to the second pipe clamp 4. A vertically arranged locking rod 51 connects the diagonal brace 5 and the cantilever rod 32.

[0052] In this embodiment, multiple guardrail vertical tubes are connected by horizontal bars via insert plates to form a guardrail with an edge protection structure.

[0053] The guardrail is securely installed on the outer side of the upper part of the disc-lock scaffold under the support of the edge protection cantilever support structure of the disc-lock scaffold of the present invention.

[0054] As a preferred implementation method, see [reference]. Figure 2 and Figure 4 As shown, the clamping assembly 13 includes: a support beam 131, clamping teeth 132, and a drive rod 133.

[0055] The supporting beam 131 is long and narrow.

[0056] The clamping teeth are arc-shaped. There are two clamping teeth 132. Each clamping tooth 132 has a root and a head opposite each other in its arc direction. The roots of the two clamping teeth 132 are respectively flipped and installed at both ends of the support beam 131.

[0057] The drive rod 133 is mounted on the support beam 131. It is used to drive the two clamping teeth 132 to rotate in opposite directions so that the heads of the two clamping teeth 132 are respectively inserted between two adjacent teeth of the two racks 12.

[0058] In this embodiment, pressure is applied to the two racks by the clamping assembly, causing the two racks to press against the uprights of the disc-lock scaffold, thereby locking the connector to the upper end of the uprights of the disc-lock scaffold. The driving rod causes the two clamping heads to flip in opposite directions.

[0059] In this embodiment, the root of the clamping tooth is pivotally connected to one side of the support beam. Each end of the support beam has a through-hole. A lever slides through the through-hole. The through-hole is along the length of the support beam. Furthermore, the support beam also has a through-hole connecting the two through-holes. A drive rod rotatably passes through the through-hole. The drive rod has an external thread. The lever has a threaded hole. The drive rod is screwed into the threaded hole of the lever in the two through-holes. The threads in the two threaded holes have opposite helical directions. When the drive rod is rotated, the two levers move relative to or away from each other.

[0060] In this embodiment, the inner arc surfaces of the two clamping teeth are arranged opposite each other. The two levers press against the outer arc surfaces of the two clamping teeth respectively. When the drive lever is rotated, the two levers move closer to each other, thereby pressing against the outer arc surfaces of the two clamping teeth, causing the heads of the two clamping teeth to move relative to each other.

[0061] like Figure 2 As shown, the head of the clamping tooth is positioned above the root of the clamping tooth. In other embodiments, the clamping tooth is inverted, i.e., the head of the clamping tooth is positioned below the root of the clamping tooth. The support beam is supported by the first pipe clamp. The clamping assembly has a fall-prevention function for the first pipe clamp. Moreover, the greater the pressure on the clamping assembly, the greater the pressure of the two clamping teeth on the two racks.

[0062] See Figure 5 As shown, in this embodiment, two compensation pads 24 are provided on the inner side of the first clamp 22. The compensation pads 24 are attached to the outer side of the upper end of the rack 12.

[0063] In a preferred embodiment, the side of the compensation pad 24 facing the rack 12 has a first tooth 25. The first tooth 25 engages with the rack 12.

[0064] The compensation pad is a rubber block.

[0065] By pressing down the upper ends of the two racks with the first clamp, the upper ends of the two racks press against the outside of the upright of the disc-lock scaffold, thereby locking the connector onto the upright of the disc-lock scaffold.

[0066] Continue reading Figure 5 As shown, the movable insert plate 21 has a perforation. The two opposite walls of the perforation have notches. Two racks 12 are accommodated in the two notches.

[0067] In a preferred embodiment, a second tooth 26 is formed on the inner wall of the notch. The second tooth 26 engages with the rack 12.

[0068] See Figure 2 and Figure 6 As shown, the upper end of the locking link 51 is fixedly connected to the cantilever rod 32. The opposite sides of the lower end of the locking link 51 are respectively connected to the diagonal brace 5 via hinges.

[0069] This invention provides a construction method for an edge protection cantilever support structure of a disc-lock scaffold, comprising the following steps:

[0070] S1. The sleeve 11 of the connector 1 is movably fitted onto the upper end of the upright of the disc-lock scaffold.

[0071] S2. Clamp the clamping assembly 13 of the connector 1 to the outer side of the middle of the two racks 12 so that the two racks 12 press against the opposite sides of the upright of the disc-lock scaffold, thereby locking the upright.

[0072] S3. Place the second pipe clamp 4 on the outside of the pipe sleeve 11.

[0073] S4. The first pipe clamp 22 of the auxiliary pipe assembly 2 is clamped on the outer side of the upper end of the two racks 12, and the movable insert plate 21 of the auxiliary pipe assembly 2 is set above the first pipe clamp 22 and movably sleeved on the outer side of the upper end of the two racks 12.

[0074] S5. The outer riser 3 is set on the outer side of the upper end of the upright, and the fixed insert plate 31 and the movable insert plate 21 of the outer riser 3 are connected to the outer riser 3 by the cantilever rod 32.

[0075] S6. The upper end of the diagonal brace 5 is detachably connected to the lower end of the outer riser 3, and the lower end of the diagonal brace 5 is detachably connected to the second pipe clamp 4.

[0076] S7. Connecting rod 51 between diagonal brace 5 and cantilever rod 32.

[0077] S8. Connect the edge protection vertical pipe 6 to the outer vertical pipe 3.

[0078] The cantilevered support structure for edge protection of the disc-lock scaffolding of this invention achieves high efficiency in the temporary erection of edge protection for full-span scaffolding while ensuring convenient and reliable construction. It allows for controllable cantilever support erection height, avoids cumbersome workload, saves construction costs, and improves overall construction efficiency on the site. It also solves many problems such as non-standard verticality of edge protection erection and safety hazards caused by excessive distance between the edge protection and the working surface. Furthermore, this support structure allows for reuse, fully complying with current green construction and green building requirements. It effectively solves related problems while significantly increasing the utilization rate of related materials and reducing costs. Due to its simple material structure and substitutability, all materials in this invention can be replaced with other suitable materials.
