Description

Technical Field

[0001] This utility model relates to the field of slope construction technology, specifically to a suspended scaffold for slope construction. Background Technology

[0002] In the construction of steep slope protection projects in the building construction field, the traditional method of building a working platform starts from the ground (base surface), uses steel pipes to build a support system to the required height, and then builds the working platform on it. This method has many drawbacks: (1) Since it needs to start from the ground, for steep slopes with large elevation differences, the amount of building materials such as steel pipes is extremely large, resulting in high costs; (2) The construction process requires a lot of manpower, which not only increases labor costs, but also makes the efficiency of manual construction relatively low; (3) The construction time is long, which prolongs the entire construction cycle; (4) In the environment of steep slopes, ground construction is restricted by the terrain, and construction workers face multiple safety risks such as falling from heights and being hit by objects, resulting in prominent safety hazards. At the same time, under complex geological conditions, ground construction may also affect the stability of the support system due to geological instability, further threatening construction safety and quality. Existing technologies have attempted to construct scaffolding by setting anchor bolts on slopes and using the anchor bolts as a support foundation to erect steel pipe frames. However, the working platforms on this type of scaffolding do not have corresponding reinforcement structures. Since the working platforms need to bear additional loads for extended periods, the connection strength at the working platforms is crucial and relates to the safety of the workers.

[0003] Therefore, it is necessary to improve the existing slope construction operation platform to effectively address the aforementioned shortcomings. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a suspended scaffold for slope construction. By constructing anchor pipes for support at a set distance on the slope and erecting scaffolding on the corresponding anchor pipes to form a suspended operating platform, the frame structure of the operating platform is also provided with a connecting structure to increase the connection strength with the slope. This makes the suspended scaffold have the advantages of improving scaffold stability, reducing construction costs, and enhancing safety protection.

[0005] This utility model provides a suspended scaffold for slope construction, comprising several anchor pipes set on the slope surface, an inner frame structure set along the slope surface, an outer frame structure parallel to the slope surface and set outside the inner frame structure, and a connecting crossbar set perpendicular to the slope surface and connected and fixed to the inner and outer frame structures. The end of the connecting crossbar near the slope surface is connected to the end of the anchor pipe extending out of the slope surface by a fastener, and an operating platform is set on the connecting crossbar.

[0006] Furthermore, an anchor rod is installed below the anchor pipe at its lowest vertical position. The anchor rod is connected and fixed to the outer frame structure and the connecting crossbar respectively through a first diagonal brace. One end of the first diagonal brace is inserted into the end of the anchor rod that extends out of the slope surface, and the other end is connected to the outer frame structure and the connecting crossbar respectively through a fastener.

[0007] Furthermore, the inner frame structure includes climbing rods set close to the slope surface, a first main horizontal bar for connecting adjacent climbing rods, and a first scissor bracing structure set between the climbing rods and the first main horizontal bar. The climbing rods, the first main horizontal bar, and the connecting horizontal bar located at the same height are connected by fasteners.

[0008] Furthermore, the outer frame structure includes vertical poles that are longitudinally parallel to the slope surface, a second large horizontal bar for connecting adjacent vertical poles, and a second scissor bracing structure disposed between the vertical poles and the second large horizontal bar. The vertical poles, the second large horizontal bar, and the connecting horizontal bar located at the same height position are connected by fasteners.

[0009] Furthermore, a second diagonal brace is provided between the upright and the climbing pole. One end of the second diagonal brace is connected to the climbing pole, the first horizontal bar, and the connecting horizontal bar located at the same floor height position via a fastener, and the other end is connected to the upright, the second horizontal bar, and the connecting horizontal bar located at the adjacent floor height position via a fastener.

[0010] Furthermore, it also includes a protective net, which is a dense mesh net fixed to the second horizontal bar and the uprights by cable ties, so that the uprights of the protective net, the second horizontal bar and the uprights together form a protective barrier.

[0011] Furthermore, a cable is also provided between the anchor pipe and the outer frame structure.

[0012] This utility model has the following beneficial effects: The suspended scaffolding for slope construction provided in this application achieves a reliable connection between the scaffolding and the slope through the coordinated arrangement of anchor pipes, inner and outer frame structures, and connecting crossbars, solving the problems of high material consumption, long construction period, and poor stability of traditional scaffolding; at the same time, the addition of anchor pipes between the connecting crossbars at the operating platform and the slope, and the connection and fixation of the connecting crossbars at this point to the anchor pipes, enhances the connection stability at the operating platform, and has the advantages of improving scaffolding stability, reducing construction costs, and enhancing safety protection.

[0019] This application proposes a suspended scaffold for slope construction, comprising several anchor pipes 2 set on the slope surface of slope 1, an inner frame structure set along the slope surface of slope 1, an outer frame structure parallel to the slope surface of slope 1 and set outside the inner frame structure, and connecting crossbars 9 set perpendicular to the slope surface and connected and fixed to the inner and outer frame structures. The end of the connecting crossbar 9 near the slope surface of slope 1 is connected to the end of the anchor pipe 2 extending out of the slope surface of slope 1 by a fastener, and an operating platform 10 is set on the connecting crossbar 9; wherein the anchor pipe 2 can be made of seamless steel pipe or threaded steel pipe, and the length is determined according to the geological conditions of slope 1. The method involves using a single-person suspended platform to drill installation holes for anchor pipes 2 on slope 1 using a pneumatic drill. The anchor pipes 2 are then fixed to the slope surface of slope 1 by grouting or filling with cementitious material, with a portion of the end of the anchor pipe 2 protruding from the slope 1. Subsequently, the anchor pipes 2 are used to construct an inner frame structure, an outer frame structure, and connecting crossbars 9 to form the overall scaffolding frame. At the same time, the end of the connecting crossbar 9 near slope 1 needs to be connected to the anchor pipes 2 on slope 1. Then, an operating platform 10 is erected on the connecting crossbar 9 to strengthen the connection strength at the operating platform 10, ensure the overall stability of the scaffolding, and enhance safety protection.

[0020] This plan utilizes a single-person suspended platform as a preliminary preparation, directly constructing the platform at the work location on the steep slope 1, reducing ground operations and reliance on ground support systems. By grooving and drilling holes in the slope surface, anchor bolts 3 and steel pipes are driven in to form a triangular frame, utilizing the stability principle of triangles to provide a reliable support foundation for the operating platform 10. After erecting scaffolding on the triangular frame, the anchor bolts 3 are used as anchor points for diagonal reinforcement, and cable 13 is used for basket fastening, further enhancing the overall stability and safety of the platform and ensuring its ability to withstand construction loads in complex construction environments. The use of specialized tools such as small mechanical grooving and pneumatic drills, along with precise construction procedures, ensures the installation quality of the anchor bolts 3 and steel pipes, thereby guaranteeing the reliability of the entire support system and the operating platform.

[0021] In this embodiment, an anchor rod 3 is installed below the anchor pipe 2 at its lowest vertical position. The anchor rod 3 is connected and fixed to the outer frame structure and the connecting crossbar 9 via a first diagonal brace 4. One end of the first diagonal brace 4 is inserted into the end of the anchor rod 3 that extends out of the slope 1, and the other end is connected to the outer frame structure and the connecting crossbar 9 via fasteners. The anchor rod 3 is made of threaded steel and is fixed in the rock mass of the slope 1 by drilling and grouting or by filling with cementitious material. The first diagonal brace 4 can be a steel pipe with a diameter of 48mm, arranged at an angle of 45-60° with the horizontal plane. The fasteners can be standard scaffolding fasteners or customized connectors to ensure that the connection part has sufficient shear and tensile strength. The connection point between the first diagonal brace 4 and the outer frame structure is located at the intersection of the upright 7, the second crossbar 8, and the connecting crossbar 9. This technical solution significantly enhances the stability of the scaffold's base structure by adding anchor rods 3 and a diagonal bracing system below the lowest anchor pipe 2. Anchor rods 3 directly transfer part of the load to the deep, stable rock mass, while the first diagonal bracing rod 4 forms a triangular stabilizing structure, effectively dispersing the bending moment and shear force transmitted by the connecting crossbar 9. This structure effectively solves the problem of insufficient support at the bottom of the scaffold on steep slope 1, avoiding the risk of overall instability due to bottom deformation, while also reducing the amount of foundation support materials required for ground erection. During construction, anchor rods 3 and the diagonal bracing system can be installed simultaneously with the scaffold erection, requiring no additional construction steps, thus ensuring structural safety and improving construction efficiency.

[0022] In this embodiment, the inner frame structure includes climbing rods 5 that are closely attached to the slope surface of the slope 1, a first horizontal bar 6 for connecting adjacent climbing rods 5, and a first scissor bracing structure disposed between the climbing rods 5 and the first horizontal bar 6. The climbing rods 5, the first horizontal bar 6 and the connecting horizontal bar 9 located at the same height position are connected by fasteners.

[0023] The climbing poles 5 are made of steel pipes or structural steel, and their lengths are segmented according to the height of slope 1. Adjacent climbing poles 5 are longitudinally extended by welding or bolting. The first horizontal bar 6 is made of steel pipe and is connected to the climbing poles 5 by right-angle couplers, with the spacing determined according to the construction load calculation. The first scissor bracing structure is composed of intersecting steel pipes and is connected to the climbing poles 5 and the first horizontal bar 6 by swivel couplers, with the intersection angle controlled within the range of 45-60 degrees. By setting the climbing poles 5, which are closely fitted to the slope surface, as the main load-bearing components, together with the horizontally connected first horizontal bar 6 and the first scissor bracing structure that enhances stability, a stable spatial force-bearing system is formed. The climbing poles 5 directly transfer the load to the rock mass of slope 1, avoiding the height accumulation effect of traditional ground support systems; the first horizontal bar 6 ensures the coordinated work of adjacent climbing poles 5; and the first scissor bracing structure effectively improves the frame's resistance to lateral displacement.

[0024] In this embodiment, the outer frame structure includes vertical poles 7 running longitudinally parallel to the slope surface 1, second horizontal bars 8 connecting adjacent vertical poles 7, and a second scissor brace 14 structure disposed between the vertical poles 7 and the second horizontal bars 8. The vertical poles 7, the second horizontal bars 8, and the connecting horizontal bars 9 located at the same height are connected by fasteners. The vertical poles 7 are made of steel pipe and are arranged longitudinally along the slope surface 1, with the spacing determined according to the construction load and the height of the slope 1. The second horizontal bars 8 are connected to the vertical poles 7 by right-angle fasteners to form a horizontal frame structure. The second scissor brace 14 structure adopts the form of intersecting steel pipes and is fixed to the vertical poles 7 and the second horizontal bars 8 by rotating fasteners, with the intersection angle maintained between 45 and 60 degrees. The connecting horizontal bars 9 are connected to the vertical poles 7 and the second horizontal bars 8 at the nodes by butt-joint fasteners to form a spatial force-bearing system. This technical solution forms a stable outer frame system through the vertical poles 7, the second horizontal bars 8, and the second scissor brace 14 structure, which together with the inner frame structure and the connecting horizontal bars 9 constitute a spatial force-bearing system. The second scissor brace 14 structure effectively enhances the lateral stiffness of the outer frame and prevents the uprights 7 from becoming laterally unstable. Through the fastener connection method, it realizes the rapid assembly and reliable force transmission between the members, solving the problems of large material consumption and low construction efficiency in traditional ground construction methods.

[0025] In this embodiment, a second diagonal brace 12 is provided between the upright 7 and the climbing pole 5. One end of the second diagonal brace 12 is connected to the climbing pole 5, the first horizontal pole 6, and the connecting horizontal pole 9 located at the same floor height via a fastener, and the other end is connected to the upright 7, the second horizontal pole 8, and the connecting horizontal pole 9 located at an adjacent floor height via a fastener. The second diagonal brace 12 can be made of steel pipe or shaped steel, and its length is determined according to the height difference between adjacent floors. The angle between the second diagonal brace 12 and the horizontal plane is controlled between 45° and 60°. During installation, both ends of the second diagonal brace 12 are connected and fixed to the corresponding components via right-angle fasteners. The second diagonal brace 12 can be arranged continuously or at intervals, and the spacing between adjacent second diagonal braces 12 should preferably be controlled between 1.5 meters and 2 meters. By setting the second diagonal brace 12, the connection rigidity between the inner frame structure and the outer frame structure can be effectively enhanced, and the overall stability of the scaffolding can be improved. The second diagonal brace 12 connects the frame structures of adjacent floors into a whole, forming a space truss structure, which can better resist lateral loads.

[0026] In this embodiment, a protective net 11 is also included. The protective net 11 is made of dense mesh and is fixed to the second horizontal bar 8 and the upright bar 7 by cable ties, so that the protective net 11, the upright bar 7, the second horizontal bar 8, and the upright bar 7 together form a protective barrier. The protective net 11 is made of dense mesh material, which can effectively block tools or debris falling during construction. The dense mesh is fixed to the second horizontal bar 8 and the upright bar 7 at multiple points by high-strength cable ties to ensure that the protective net 11 is firm and reliable. The protective net 11 can be continuously arranged along the outer side of the outer frame structure to form a complete protective surface.

[0027] Therefore, this technical solution effectively solves the problem of falling objects during high-altitude operations by installing a protective net 11 on the outside of the suspended scaffold. Compared with existing technologies, this solution has the following advantages: First, the protective net 11 is directly fixed to the main structure of the scaffold, eliminating the need for an additional support system and simplifying the installation process; second, the dense mesh netting material is lightweight and high-strength, ensuring both protective effectiveness and minimal increase in the scaffold load; finally, the integrated design of the protective net 11 and the scaffold allows for flexible adjustment of the protection range according to the construction progress, improving construction safety. This solution is particularly suitable for construction environments on steep slopes, effectively reducing the risk of falling objects and ensuring the safety of construction personnel and equipment below.

[0028] In this embodiment, a cable 13 is also provided between the anchor pipe 2 and the outer frame structure. The cable 13 can be a high-strength flexible connector such as steel wire rope or steel strand. One end of the cable is fixedly connected to the anchor pipe 2 through an anchor, and the other end is connected to the upright 7 or the second horizontal bar 8 of the outer frame structure through an adjustment device such as a shackle or turnbuckle. This technical solution effectively solves the problem of insufficient lateral stability of the scaffolding during the construction of steep slopes 1 by adding a cable 13 system between the main structure of the suspended scaffolding and the anchoring point of the slope 1. The cable 13 directly transfers the horizontal load borne by the outer frame to the rock mass of the slope 1, significantly reducing the bending moment stress of the connecting horizontal bar 9, and at the same time, the pre-tension force counteracts the displacement tendency of the scaffolding caused by the construction load. Compared with the traditional method of relying solely on diagonal braces, the cable 13 system has the advantages of clear force path and convenient adjustment, and is particularly suitable for construction environments with complex geological conditions or strong wind loads. Therefore, under the premise of ensuring the same safety factor, the number of diagonal braces can be appropriately reduced, simplifying the on-site installation process.
