Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for decorating and renovating a slope roof. Background Art

[0002] The traditional decoration method requires the construction of double-row scaffolding outside the building so that the operators can safely climb onto the roof for construction. Although this scaffolding construction method provides a stable operating platform for the workers, it also brings some problems.

[0003] First of all, the erection of scaffolding itself consumes a lot of time and resources, which not only increases the cost of the project, but also affects the smooth progress of the project due to potential safety hazards during the erection process. Secondly, the existence of scaffolding conflicts with the normal use of vertical transportation equipment such as hanging baskets. In the process of exterior wall decoration, hanging baskets are a very important construction tool that can efficiently transport materials and workers and improve construction efficiency. However, when scaffolding and hanging baskets are used in the same space, mutual interference not only reduces the efficiency of the use of the hanging baskets, but also causes safety accidents.

[0004] Therefore, in the decoration process of slope roof structure, how to resolve the conflict between scaffolding erection and hanging basket use, improve construction efficiency and ensure construction safety has become a technical problem that needs to be solved urgently in the current construction industry. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a scaffold for slope roof decoration and renovation, so as to realize the efficient advancement of building decoration and renovation projects.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A scaffold for slope roof decoration and renovation comprises:

[0008] A cantilevered horizontal bar, one end of which is connected to the connecting wall;

[0009] A guardrail longitudinal rod, one end of which is connected to the other end of the cantilevered crossbar by a fastener, and the other end of which is connected to the eaves end of the slope roof to form a scaffold;

[0010] A bottom cross bar is arranged on the eaves of the sloping roof;

[0011] A skirting board, fixed on the longitudinal rod of the guardrail, with a height of ≥200mm, and arranged on the upper part of the eaves of the slope roof;

[0012] A inner corner support plate is anchored on the bottom cross bar;

[0013] The bottom vertical rod is connected to the bottom horizontal rod via a fastener;

[0014] A dense safety net is laid on the outer side and the inner side of the facade surrounded by the bottom vertical poles.

[0015] Furthermore, one end of the cantilevered cross bar is fixed on both sides of the connecting wall by a first connecting wall upright bar and a second connecting wall upright bar.

[0016] Furthermore, the cantilevered horizontal bar extends out from the connecting wall and the second vertical bar of the connecting wall by 150 mm from the outer edge, and extends out from the edge of the guardrail longitudinal bar by ≥ 150 mm.

[0017] Furthermore, the joints of two adjacent connecting longitudinal bars and vertical bars of the guardrail, the first vertical bars connected to the wall and the second vertical bars connected to the wall are not arranged in the same synchronization or span, and the horizontal offset distance of two adjacent joints that are not synchronized or in different spans is ≥ 500mm, and the distance from the center of each joint to the main node is ≤ 1 / 3 of the longitudinal distance.

[0018] Furthermore, the overlapping length of the guardrail longitudinal bar, the first vertical bar connected to the wall and the second vertical bar connected to the wall is ≥ 1m, three rotating fasteners are arranged at equal intervals for fixing, and the overlapping distance between the edge of the fastener at the left end of the cantilevered cross bar and the guardrail longitudinal bar is ≥ 100mm.

[0019] Furthermore, the bottom cross bars are arranged in parallel, equal length and equidistant on the same plane, and the spacing between them is no more than 1.5 meters.

[0020] Furthermore, a spiral rod is provided on the internal angle supporting plate, and the spiral hole penetrating the internal angle supporting plate cooperates with a gasket and a nut to anchor the bottom cross bar.

[0021] Furthermore, the bottom uprights are arranged in parallel, equal length and equal distance on the same plane, and the vertical distance is no more than 1.5 meters.

[0022] The above solution of the utility model includes at least the following beneficial effects:

[0023] A stable scaffolding structure is constructed by connecting the cantilevered crossbar to the wall, and connecting the guardrail longitudinal bar to the cantilevered crossbar and the eaves of the sloping roof. This structure provides a safe working platform for construction workers and effectively reduces the risk of falling from heights. The bottom crossbar is set on the eaves of the sloping roof and anchored by the inner corner support plate, which enhances the foundation stability of the scaffolding. The bottom vertical bar is connected to the bottom crossbar by fasteners to ensure the stability of the overall structure. The height of the skirting board is set to ≥200mm and is located on the upper part of the eaves of the sloping roof, which effectively prevents construction workers and tools from slipping off the edge of the scaffolding.

[0024] At the same time, the dense safety net is laid on the outside and inside of the facade surrounded by the bottom vertical pole, providing comprehensive protection to prevent the falling of tools and materials, and also protecting the construction workers from the external environment. The fastener connection method makes the installation and disassembly of the scaffolding relatively simple and quick, improving the construction efficiency. The scaffolding design can adapt to roofs of different slopes, and can flexibly cope with various construction environments by adjusting the position and angle of the bottom cross bar, bottom vertical pole and guardrail longitudinal pole.

DETAILED DESCRIPTION

[0029] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] like Figures 1 to 3 As shown, the embodiment of the utility model provides a scaffolding for slope roof decoration, comprising:

[0031] A cantilevered crossbar 14, one end of which is connected to the connecting wall;

[0032] The guardrail longitudinal rod 11 has one end connected to the other end of the cantilever crossbar 14 through a fastener, and the other end connected to the eaves end of the slope roof to form a scaffold;

[0033] A bottom cross bar 2 is arranged on the eaves of the sloping roof;

[0034] The skirting board 10 is fixed on the guardrail longitudinal rod 11, has a height of ≥200mm, and is arranged on the upper part of the eaves of the slope roof;

[0035] The inner corner support plate 3 is anchored on the bottom cross bar 2;

[0036] The bottom vertical rod 7 is connected to the bottom cross rod 2 via fasteners;

[0037] A dense safety net 9 is laid on the outer side and the inner side of the facade surrounded by the bottom vertical pole 7.

[0038] In the embodiment of the utility model, one end of the cantilever crossbar 14 is connected to the wall of the building, providing a stable cantilever support point for the scaffolding. The scaffolding can be extended to the outside of the building, which is convenient for construction workers to decorate the slope roof. One end of the guardrail longitudinal bar 11 is connected to the cantilever crossbar through a fastener, and the other end is connected to the eaves end of the slope roof. In this way, the guardrail longitudinal bar not only provides a safety guardrail for construction workers, but also enhances the connection stability between the scaffolding and the building. The bottom crossbar 2 is arranged on the eaves of the slope roof and is the basic support structure of the entire scaffolding. The stability of the scaffolding is ensured by anchoring with the inner corner support plate. The skirting board 10 is fixed on the guardrail longitudinal bar, with a height of at least 200mm, and is located at the upper part of the eaves of the slope roof. Its main function is to prevent tools or materials from slipping off the edge of the scaffolding, and also provides certain safety protection for construction workers. The inner corner support plate 3 is used to anchor the bottom crossbar, which enhances the connection strength between the scaffolding and the building and ensures the stability of the scaffolding. The bottom vertical rod 7 is connected to the bottom cross bar by fasteners, forming the vertical support structure of the scaffold. The bottom vertical rods are connected by connecting longitudinal rods and other connectors to form a stable frame to support the working platform of the scaffold. The dense safety net 9 is laid on the outside and inside of the vertical surface surrounded by the bottom vertical rods, forming a comprehensive safety protection barrier. It can prevent construction workers from falling and block external objects from entering the interior of the scaffold, ensuring the safety of construction workers.

[0039] The overall stability of the scaffolding has been improved through the reasonable layout and connection of the cantilever crossbars, guardrail longitudinal bars and bottom crossbars. It can effectively resist external wind forces and dynamic loads during construction to ensure the safety of construction workers. The setting of skirting boards and dense safety nets provides all-round safety protection for construction workers. The skirting boards prevent the slipping of tools and materials, while the dense safety nets effectively block external objects and the risk of falling. The scaffolding design can adapt to roofs of different slopes and shapes. By adjusting the position and angle of each rod, it can flexibly respond to various construction environments. This flexibility enables scaffolding to play an important role in complex slope roof decoration and renovation projects. The use of fasteners makes the installation and disassembly of the scaffolding simple and quick.

[0040] like Figures 1 to 3 As shown, one end of the cantilevered cross bar 14 is fixed on both sides of the connecting wall by a first connecting wall upright bar 12 and a second connecting wall upright bar 13 .

[0041] In the embodiment of the utility model, the first wall connecting rod 12 and the second wall connecting rod 13 are arranged on both sides of the wall, and their main function is to fix one end of the cantilever cross bar 14. Through these two rods, the cantilever cross bar can be stably connected to the wall, thereby ensuring the stability of the entire scaffolding structure. The cantilever cross bar 14 is an important part of the scaffolding, one end of which is fixed to the wall through the first wall connecting rod and the second wall connecting rod, and the other end is cantilevered outward to provide support for the scaffolding. The scaffolding can be extended to the outside of the building, which is convenient for construction workers to carry out decoration and renovation work on the slope roof.

[0042] One end of the cantilever cross bar is fixed to the wall by the first wall-connected vertical pole 12 and the second wall-connected vertical pole 13, which significantly enhances the stability of the scaffolding. The double-fixed design can effectively resist external wind force and dynamic loads during construction, ensuring the safety of construction workers. The fixing method of the two vertical poles improves the bearing capacity of the cantilever cross bar, so that it can withstand greater construction loads and meet complex construction requirements. The design of the first wall-connected vertical pole and the second wall-connected vertical pole makes the installation of the cantilever cross bar easier. Construction workers only need to fix one end of the cantilever cross bar between the two vertical poles to complete the installation, thereby improving construction efficiency. This fixing method can adapt to walls of different thicknesses, and by adjusting the positions of the two vertical poles, it can flexibly cope with various construction environments.

[0043] like Figures 1 to 3 As shown, the cantilevered horizontal bar 14 extends out of the connecting wall and the second vertical bar 13 of the connecting wall by 150 mm from the outer edge, and extends out of the edge of the guardrail longitudinal bar 11 by a distance ≥ 150 mm.

[0044] In the embodiment of the utility model, the cantilevered crossbar 14 is designed to extend 150mm beyond the outer edge of the connecting wall and the second connecting wall vertical bar 13, which means that the crossbar is not only firmly connected to the wall, but also has an extra length cantilevered outward. At the same time, the cantilevered crossbar also extends beyond the edge of the guardrail longitudinal bar 11, and the distance of this extension is at least 150mm. The connecting wall and the second connecting wall vertical bar 13 serve as the support points of the cantilevered crossbar, ensuring that the crossbar is stably fixed to the wall, and the cantilevered part provides a larger working space for the scaffold.

[0045] The guardrail longitudinal bars 11 are connected to the cantilevered cross bars 14, but the extended design of the cantilevered cross bars ensures that even if the construction workers are close to the guardrail longitudinal bars during work, there is enough space to avoid direct contact with the edge of the building, thereby improving safety.

[0046] The extended design of the cantilevered crossbar provides construction workers with greater operating space, making it easier for them to carry out various decorative and renovation work on the scaffolding, especially at the edge of the sloped roof. By ensuring that the cantilevered crossbar extends at least 150mm beyond the edge of the guardrail longitudinal bar, the risk of construction workers approaching or falling off the edge of the building due to misoperation is reduced, thereby significantly improving construction safety. This design also allows the scaffolding structure to be more flexible and can adapt to sloped roofs of different shapes and sizes while maintaining the stability and safety of the structure.

[0047] The reach setting may meet or exceed industry safety standards, helping to ensure that construction sites comply with relevant laws and regulations and avoid safety accidents caused by illegal operations.

[0048] like Figures 1 to 3 As shown, the guardrail longitudinal rod 11, the first wall vertical rod 12 and the second wall vertical rod 13, the joints of two adjacent connecting longitudinal rods and vertical rods are not arranged in the same synchronization or span, and the horizontal offset distance of two adjacent joints that are not synchronized or in different spans is ≥ 500mm, and the distance from the center of each joint to the main node is ≤ 1 / 3 of the longitudinal distance.

[0049] In an embodiment of the utility model, the guardrail longitudinal rod 11, the first wall connecting rod 12 and the second wall connecting rod 13 are important components of the scaffolding, which are connected to each other by connecting the longitudinal rods to form a stable frame. In this frame, the joints of two adjacent connecting longitudinal rods and vertical rods are carefully designed to ensure the stability and safety of the structure. The joints of two adjacent connecting longitudinal rods and vertical rods are not set in synchronization or the same span, which means that the joints are staggered in both horizontal and vertical directions. This design increases the overall stability of the scaffolding and avoids structural weaknesses caused by the concentration of joints in the same position. The horizontal staggered distance of two adjacent joints that are not synchronized or have different spans is at least 500mm, ensuring that there is enough distance between the joints to reduce the risk of stress concentration and structural failure. At the same time, the distance from the center of each joint to the main node does not exceed 1 / 3 of the longitudinal distance, which helps to maintain the uniformity and stability of the scaffolding structure.

[0050] The structural stability of the scaffolding is improved through the carefully designed joint arrangement. The staggered design of the joints avoids stress concentration and reduces the risk of structural failure, thus ensuring the safety of construction workers.

[0051] Due to the uniformity and rationality of the joint distribution, the load-bearing capacity of the scaffolding is improved. This design enables the scaffolding to withstand greater construction loads and meet the needs of complex construction. Reasonable joint design reduces the possibility of stress concentration and fatigue failure, thereby extending the service life of the scaffolding. The layout and design of the joints may meet or exceed industry safety standards, helping to ensure that the construction site complies with relevant laws and regulations. This can not only avoid safety accidents caused by illegal operations, but also improve the overall safety of the construction site.

[0052] like Figures 1 to 3 As shown, the overlapping length of the guardrail longitudinal rod 11, the first wall vertical rod 12 and the second wall vertical rod 13 is ≥ 1m, 3 rotating fasteners are arranged at equal intervals for fixing, and the distance between the left end fastener edge of the cantilevered cross bar 14 and the guardrail longitudinal rod 11 is ≥ 100mm.

[0053] In an embodiment of the utility model, the overlap length between the guardrail longitudinal rod 11, the first wall connecting rod 12 and the second wall connecting rod 13 is set to be greater than or equal to 1 meter. Within this overlap length, three rotating fasteners are set at equal intervals for fixing. This design ensures the connection stability and load transfer ability between the rods. The overlap distance between the left end fastener edge of the cantilever crossbar 14 and the guardrail longitudinal rod 11 is set to be greater than or equal to 100 mm. This design ensures the effective connection between the cantilever crossbar and the guardrail longitudinal rod, while avoiding structural weaknesses caused by insufficient overlap.

[0054] By ensuring sufficient overlap length and using rotating fasteners for fixing, the connection stability between the guardrail longitudinal rod, the first wall connecting rod and the second wall connecting rod is improved. The relative movement between the rods is effectively prevented, thereby enhancing the stability of the overall structure. Sufficient overlap length and firm fixing method reduce the risk of structural failure and provide a safer working environment for construction personnel. At the same time, sufficient overlap distance between the cantilever crossbar and the guardrail longitudinal rod also ensures the integrity and safety of the structure. Using rotating fasteners for fixing simplifies the installation and disassembly process and improves construction efficiency. The design of the rotating fastener makes the connection between rods more flexible and convenient. It can adapt to rods of different lengths and diameters, improving the versatility and flexibility of the scaffolding system. By adjusting the overlap length and the position of the fasteners, it can easily adapt to various construction environments and needs.

[0055] like Figures 1 to 3 As shown, the bottom cross bars 2 are arranged in parallel, equal length and equal distance on the same plane, and the spacing is no more than 1.5 meters.

[0056] In the embodiment of the utility model, the bottom crossbars 2 are arranged in parallel, equal length and equidistant on the same plane. This layout ensures uniform support and stability of the bottom of the scaffold. The spacing between the bottom crossbars is strictly controlled and is no more than 1.5 meters, which can ensure the bearing capacity of the scaffold and the stability of the overall structure. The bottom crossbars are arranged in parallel, equal length and equidistant, providing a uniform and stable support foundation for the scaffold. This layout helps to disperse the load and prevent structural imbalance or local overload caused by uneven support.

[0057] By controlling the spacing between the bottom crossbars to no more than 1.5 meters, it can be ensured that the scaffolding has sufficient strength and rigidity when bearing construction loads. Smaller spacing means more support points, thereby improving the overall load-bearing capacity. The evenly arranged bottom crossbars reduce the shaking and instability of the scaffolding during use, providing a safer working environment for construction workers. In addition, strict spacing control also reduces safety risks caused by structural problems. The regular arrangement of the bottom crossbars simplifies the installation and disassembly process of the scaffolding. Construction workers can complete the erection and dismantling work faster, improving construction efficiency. The layout of the bottom crossbars of equal length and equal distance helps to optimize material use and reduce waste. This design ensures that each bottom crossbar can fully play its supporting role and improve the efficiency of material utilization.

[0058] like Figures 1 to 3 As shown, a spiral rod 4 is provided on the internal angle supporting plate 3, and the spiral hole penetrating the internal angle supporting plate 3 cooperates with the gasket 6 and the nut 5 to anchor the bottom cross bar 2.

[0059] In the embodiment of the utility model, the inner corner support plate 3 is a key component used to enhance the support stability of the scaffold at the inner corner position. The spiral rod 4 penetrates the preset spiral hole on the inner corner support plate 3, and through the cooperation of the gasket 6 and the nut 5, the bottom cross bar 2 is tightly anchored at the inner corner position. The scaffold can be additionally reinforced at the corner position, thereby improving the stability of the overall structure.

[0060] Through the coordinated use of the internal corner support plate and the spiral rod, the support stability of the scaffolding at the internal corner position has been significantly enhanced. This design effectively prevents the scaffolding from shaking and shifting at the corner position, ensuring safety during the construction process. The reinforcement of the internal corner position helps to improve the stability of the overall structure of the scaffolding. Since the corner is the weak link of the structure, the risk of structural deformation and damage can be effectively reduced by adding internal corner support plates and spiral rods for anchoring. It has a certain degree of flexibility and adaptability, and the length and position of the spiral rod can be adjusted according to actual needs to meet the needs of different corner sizes and shapes. The use of spiral rods, washers and nuts for anchoring simplifies the installation process. Construction personnel only need to pass the spiral rod through the spiral hole of the internal corner support plate, and then add washers and nuts to tighten it. The operation is simple and quick.

[0061] like Figures 1 to 3 As shown, the bottom uprights 7 are arranged in parallel, equal length and equal distance on the same plane, and the vertical distance is not more than 1.5 meters.

[0062] In the embodiment of the utility model, the bottom uprights 7 are vertical support elements in the scaffold structure, which are arranged in parallel, equal length and equidistant on the same plane. This layout ensures the vertical stability of the scaffold and the uniformity of the overall structure. The longitudinal distance between the bottom uprights is strictly controlled and is not greater than 1.5 meters to maintain the stability and load-bearing capacity of the structure. The parallel, equal length and equidistant arrangement of the bottom uprights provides uniform vertical support for the scaffold and enhances the overall vertical stability. This layout helps prevent the scaffold from tilting or twisting in the vertical direction.

[0063] The equidistant bottom poles ensure the uniformity of the scaffolding structure and avoid stress concentration or structural weaknesses caused by uneven support points. The load-bearing capacity of the scaffolding is improved by controlling the vertical distance between the bottom poles to no more than 1.5 meters. Smaller vertical distances mean denser support structures that can better disperse and withstand construction loads. The stable bottom pole layout provides a safe working environment for construction workers and reduces safety risks caused by scaffolding instability. The regular arrangement of bottom poles simplifies the scaffolding construction process and improves construction efficiency. Construction workers can locate and install bottom poles faster, saving time and costs.

[0064] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
