Description

Technical Field

[0001] The present application relates to the field of ancient building and antique building repair, and in particular to a high-rise non-tied, multi-layer cantilever scaffolding with a truss canopy and a construction method. Background Art

[0002] Since most of the ancient buildings are characterized by a wide bottom and narrow top or a double-eaved roof with receding layers, the roof and oil painting construction will involve multiple layers of construction operation surfaces. If ordinary scaffolding erection methods are used, support poles need to be set up on the lower roof to support the upper operation surface. The lower construction can only be carried out after the upper construction is completed, which will cause slow construction progress and delayed construction period, greatly reducing construction efficiency.

[0003] In addition, the repair of ancient buildings is greatly affected by weather factors, so protective measures are particularly important during the repair process, especially when it comes to the repair of ancient buildings with high building heights and large spans, which cannot be covered. How to protect large wooden components, finished products such as oil paintings, and mud and ash backs to ensure that the construction period is not affected is a difficult problem. Setting up a protective canopy is the best way. However, when setting up the canopy, it is very difficult to set up a stable canopy because of the high building height, large open area with large wind load, large building span, and the inability of the ancient building scaffolding to be connected to the main building.

[0004] For example, a high-rise, non-tied, multi-layer cantilever scaffold and method with a truss canopy. This invention solves the problems that the scaffold cannot be properly tied to the ancient building structure, the frame body is poor in stability, the multi-layer operating surfaces cannot be constructed at the same time, the construction period is delayed, and the repair process is affected by seasonal weather, which will cause rain and snow damage to the building components. The scaffold adopts a truss canopy, including a truss structure and a canopy structure, and rods connected to the truss structure and the canopy structure. Specifically, the scaffold consists of a ground-based scaffold and a vehicle stabilizing frame, and adopts structures such as horizontal diagonal supports, horizontal scissor braces and diagonal braces to ensure that the multi-layer cantilever operating surfaces are constructed at the same time, thereby ensuring that the repair of the ancient building is not affected by seasonal weather, so that the protection of cultural relics and the construction period are reliably guaranteed.

[0005] However, when the above-mentioned truss canopy is built according to the architectural style, the construction is complicated, time-consuming and the construction efficiency is low. Summary of the invention

[0006] In order to improve the efficiency of building a truss canopy, the present application provides a high-rise, tie-free, multi-layer cantilever scaffold with a truss canopy and a building method.

[0007] In the first aspect, the present application provides a high-rise non-tie, multi-layer cantilever scaffold with a truss canopy, which adopts the following technical solution: A high-rise non-tie, multi-layer cantilever scaffold with a truss canopy, comprising: The main body structure includes a truss structure, a canopy structure, a floor-type scaffolding, a vehicle stabilizing frame, a transverse diagonal support, a horizontal scissor support and a diagonal support. The truss structure is used to form an overall frame. The canopy structure is fixed on the truss structure to shield against wind and rain. The floor-type scaffolding is used to support the truss structure. The vehicle stabilizing frame is arranged on the floor-type scaffolding to enhance the stability of the scaffolding. The transverse diagonal support is arranged between the truss structures to increase the stability of the structure. The horizontal scissor support is arranged in the horizontal direction of the truss structure to improve the overall rigidity of the structure. The diagonal support is arranged in the vertical direction of the truss structure to prevent the structure from tilting. The detachable or telescopically adjustable extension part is arranged on the outside of the scaffolding and is used to adjust the distance between the scaffolding and the ancient building.

[0008] By adopting the above technical scheme, firstly, the truss structure as the overall framework not only enhances the structural strength of the scaffolding, but also provides a stable support platform, which is suitable for simultaneous construction of multi-layer construction operation surfaces and significantly improves the construction efficiency; secondly, the canopy structure is fixed on the truss structure, which can effectively block wind and rain, protect the components of the ancient building from the influence of bad weather, and ensure the smooth progress of the construction process; thirdly, the combined design of the ground-type scaffolding and the vehicle stabilizing frame increases the stability of the scaffolding, especially when working at high altitudes, effectively preventing the risk of shaking and tipping of the scaffolding; in addition, the setting of multiple transverse diagonal supports, horizontal scissor braces and diagonal braces further enhances the structural rigidity and wind resistance of the entire scaffolding, ensuring the safety and reliability of the construction process. At the same time, by setting a detachable or telescopically adjustable extension part on the outside of the scaffolding, the distance between the scaffolding and the ancient building can be flexibly adjusted to ensure that workers can easily access the ancient building for construction, which not only improves the convenience and safety of construction, but also is suitable for ancient buildings of different heights and shapes, enhances the versatility and scope of application of the scaffolding, and improves the efficiency of scaffolding construction.

[0009] Preferably, the detachable or telescopically adjustable extension portion comprises a telescopically adjustable extension rod and a fixing fixture for fixing the extension rod to the ground-mounted scaffold.

[0010] By adopting the above technical scheme, the detachable or telescopically adjustable extension part can flexibly adjust the distance between the scaffolding and the ancient building, so that workers can carry out construction at a position closer to the ancient building, improving the convenience and safety of construction. The longitudinal telescopic adjustment function of the extension rod can accurately adjust the distance between the scaffolding and the ancient building according to actual needs to ensure construction accuracy; the design of the fixing clamp ensures the stability and reliability of the extension rod, avoids loosening or falling off due to changes in the external environment, and further improves the stability of the entire scaffolding system.

[0011] Preferably, the extension rod is configured as a multi-section telescopic rod, and a locking device is provided between two adjacent sections of the telescopic rod.

[0012] By adopting the above technical solution, the design of the multi-section telescopic rod makes the extension rod have excellent flexibility and adjustability, and can be appropriately adjusted according to the shape of the building, which facilitates construction and improves construction efficiency.

[0013] Preferably, the telescopic rod is provided with a sliding track, and the telescopic arm can slide freely on the track.

[0014] By adopting the above technical solution, a sliding track is set on the telescopic rod, and the sliding track provides stable support and guidance for the telescopic arm, ensuring that it always remains stable during the movement.

[0015] Preferably, the truss structure comprises a plurality of standard modules, each module having the same size and structure, and being spliced ​​into a complete truss structure through connectors.

[0016] By adopting the above technical solution, the truss structure is composed of multiple standard modules, each module has the same size and structure, and is spliced ​​into a complete truss structure through connectors. This not only improves the assembly speed and flexibility of the scaffolding, but also can adapt to the length and width requirements of different ancient buildings, realize the function of rapid splicing, and further improve the efficiency of scaffolding construction; at the same time, the design of standardized modules also simplifies transportation and storage, and reduces construction costs.

[0017] Preferably, the connecting piece includes a latch and a locking nut, and a male head and a female head are respectively arranged at adjacent connection positions of the standard modules. The male head and the female head are connected by plugging, and a connecting hole for the latch to pass through is provided at the connection position. The locking nut is used to fix the latch and prevent it from falling off.

[0018] By adopting the above technical solution, male and female heads are set for plugging, which facilitates the connection of adjacent standard modules. By opening connection holes at the connection positions and using plugs for connection, the connection process between modules is simplified, so that standard modules can be quickly spliced ​​into a complete truss structure, thereby improving the construction speed. At the same time, the use of locking nuts further enhances the reliability of the connection parts, prevents the plugs from falling off due to external forces during the construction process, and ensures the stability of the entire scaffolding.

[0019] Preferably, the standard modules are configured as cuboids, and a support structure is provided inside each of the standard modules, and the support structure supports the main structure of the standard module.

[0020] By adopting the above technical solution, the standard module is arranged into a cuboid, which is convenient for splicing and combination. By setting a supporting structure inside the standard module, the overall bearing capacity and seismic performance of the module are improved.

[0021] Preferably, the support structure includes support columns and reinforcing ribs, and the reinforcing ribs are cross-arranged and / or grid-shaped.

[0022] By adopting the above technical solution, the cross-setting and grid-like reinforcement ribs support each other in multiple directions to form a solid frame structure, thereby effectively dispersing and bearing stress from all sides, preventing the structure from being deformed or damaged when subjected to external forces, and significantly improving the overall strength and stability of the supporting structure. Through reasonable cross- and grid-layout, the use of materials can be minimized while ensuring the strength of the structure, thereby achieving lightweight structure, which not only reduces the cost of manufacturing and transportation, but also facilitates rapid installation and disassembly on site.

[0023] In a second aspect, the present application provides a method for constructing a high-rise non-tie, multi-layer cantilever scaffold with a truss canopy, which adopts the following steps: Put up floor-to-ceiling scaffolding around the ancient buildings; Install the vehicle stabilizing frame on the ground-mounted scaffolding and adjust the height of the adjusting feet so that the stabilizing frame is level with the ground; Splice the standard modules of the truss structure to form a complete truss structure; Install the support frame on the truss structure and lay the tarpaulin, making sure that the tarpaulin completely covers the top of the truss structure; Install a detachable or telescopic extension part on the outside of the scaffolding, and adjust the length of the extension rod so that the distance between the scaffolding and the ancient building is 0.5m to 1.5m; Install safety nets around the scaffolding to ensure the safety of the construction area.

[0024] By adopting the above technical solution and the design of multi-layer cantilevered operating surfaces, multi-layer construction can be carried out simultaneously, which significantly improves construction efficiency and reduces construction period. The detachable or telescopic extension part can adjust the distance between the scaffolding and the ancient building according to actual needs, making it convenient for workers to contact the ancient building for fine construction. The truss structure adopts standard module splicing, which improves the assembly speed, adapts to the length and width of different ancient buildings, realizes the function of rapid lap connection, and improves the construction efficiency.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a detachable or telescopic extension part on the outside of the scaffolding, the distance between the scaffolding and the ancient building can be flexibly adjusted to ensure that workers can easily access the ancient building for construction.

[0027] The main structure includes a truss structure, a canopy structure, a floor-standing scaffolding, a vehicle stabilizing frame, a transverse diagonal support, a horizontal scissor brace and a diagonal support. Among them, the truss structure is used to form an overall frame, the canopy structure is fixed on the truss structure to block wind and rain, the floor-standing scaffolding is used to support the truss structure, the vehicle stabilizing frame is set on the floor-standing scaffolding to enhance the stability of the scaffolding, multiple transverse diagonal supports are set between the truss structures to increase the stability of the structure, the horizontal scissor brace is set in the horizontal direction of the truss structure to improve the overall rigidity of the structure, and the diagonal support is set in the vertical direction of the truss structure to prevent the structure from tilting. This design effectively improves the stability of the scaffolding and the simultaneous construction capability of multi-layer operating surfaces, thereby significantly improving construction efficiency and safety.

[0028] Specifically, the truss structure includes a plurality of standard modules, each module having the same size and structure, and is spliced ​​into a complete truss structure through connectors. Each standard module can be connected by a latch and a locking nut, the latch is inserted into the connection hole of the adjacent module, and the locking nut fixes the latch to prevent the latch from falling off. In one embodiment, a male head and a female head are respectively provided between the standard module and the adjacent standard module, the male head is inserted into the female head, a connection hole is opened at the connection, and then the latch is inserted into the connection hole, and the latch is fixed with a locking nut to prevent it from falling off.

[0029] Standard modules are equipped with supporting structures such as supporting columns and reinforcing ribs. These structures can be arranged in a cross or grid pattern to enhance the rigidity and stability of the module. The supporting columns can be designed as hollow tubes or solid columns, depending on the specific size and load-bearing requirements of the module. The hollow tube supporting structure has a lighter weight and better bending resistance, and is suitable for occasions with strict weight requirements. The solid columnar supporting structure has a higher load-bearing capacity and compressive resistance, and is suitable for occasions that need to withstand larger loads. In order to improve the connection strength between the reinforcing ribs and the supporting structure, welding, riveting or bolting can be used. Ensure that the connection is firm and reliable, can effectively transfer stress, and avoid connection failure.

[0030] This modular structural design is not only convenient for transportation and assembly, but also allows the size and shape of the trusses to be flexibly adjusted according to the actual needs of the construction site. For example, for ancient buildings of different heights and spans, the number of standard modules can be increased or decreased to adapt to different construction environments. In addition, the standard modules are internally provided with supporting structures, such as supporting columns and reinforcing ribs, which can be cross-set or grid-like to enhance the rigidity and stability of the modules.

The secondary beam is vertically arranged between the main beams to increase the supporting strength. The waterproof cloth can be made of high-strength PVC material, which has good waterproof and tear resistance and can effectively resist the influence of bad weather. The main beam and secondary beam of the supporting frame can be made of aluminum alloy or steel, which has the characteristics of light weight and high strength, which not only ensures the stability of the structure but also reduces the weight of the entire scaffolding.

The vehicle stabilizing frame includes a stabilizing bracket and an adjusting foot. The adjusting foot is set at the bottom of the stabilizing bracket to adjust the height of the stabilizing bracket so that the stabilizing bracket is level with the ground. This design not only ensures the stability of the scaffolding, but also adapts to the construction needs under different terrain conditions.

[0033] Multiple transverse diagonal braces are arranged between the truss structures to increase the stability of the structure. The transverse diagonal braces can be made of steel or aluminum alloy and have high strength and rigidity. Horizontal scissor braces are arranged in the horizontal direction of the truss structure to increase the overall rigidity of the structure. The horizontal scissor braces can be arranged in a cross-shaped manner and fixed to the truss structure through connectors to form a stable triangular structure. Diagonal braces are arranged in the vertical direction of the truss structure to prevent the structure from tilting. The diagonal braces can be made of steel or aluminum alloy and fixed to the truss structure through connectors to form a stable support system.

[0034] Safety nets are set around the scaffolding to prevent people from falling. The safety net can be made of high-strength nylon or polyester fiber materials with good toughness and anti-aging properties. The edges of the safety net are fixed to the scaffolding with metal hooks or straps to ensure that it will not fall off during construction.

The extension part includes a telescopic extension rod and a fixing fixture. The extension rod can be designed with a multi-section telescopic rod, and a locking device is set between two adjacent sections of the telescopic rod. The telescopic rod is provided with a sliding track, and the telescopic arm can slide freely on the track. The fixing fixture can be snap-on or screw-fixed to meet the requirements of different construction environments. The design of the fixing fixture also takes into account the needs of fast loading and unloading. Workers can complete installation and disassembly in a short time, which improves construction efficiency.

The combined design of the ground-based scaffolding and the vehicle stabilizing frame increases the stability of the scaffolding and ensures the safety of the construction process.
