Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically, it relates to a pull-out wall-mounted mesh. Background Technology
[0002] Wall-mounted safety netting is a mesh structure used in construction for protection and safety. It is typically fixed to the perimeter of a building or near formwork to prevent people or objects from falling from heights during construction. It is very common in the construction of high-rise buildings, bridges, and steel structures. Traditional wall-mounted safety netting requires installation and adjustment before construction, a process that often conflicts with other construction tasks and affects the efficiency of construction workers. If the wall-mounted safety netting is not designed for quick removal during formwork dismantling, it will increase additional time and labor costs, and is prone to insecure installation or incomplete removal. Especially after the wall-mounted safety netting is removed, construction workers may be exposed to the risk of falling from heights due to lack of protection, particularly in the absence of adequate safety precautions.
[0003] Using conventional methods of installing safety netting against the wall presents several construction difficulties, particularly before formwork erection and closure. The netting may obstruct worker operations, leading to delays. Furthermore, during formwork removal, the netting may be removed due to interference with dismantling work, further increasing safety risks, especially the risk of falls from heights. Summary of the Invention
[0004] In view of this, the present invention provides a pull-out wall-mounted mesh that can solve the technical problem that traditional wall-mounted meshes can hinder the operation of construction workers and interfere with construction work.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a pull-out wall-mounted safety net, comprising connecting fasteners, short horizontal bars, anti-slip fasteners, and long horizontal bars. The connecting fasteners include a connector and a sleeve; the sleeve is cylindrical and fixedly connected to the connector on one side. At least two short horizontal bars are fixed parallel to the wall side of the scaffolding via the connecting fasteners, with the connector of the connecting fastener located on the wall-side of each short horizontal bar, and the corresponding sleeves arranged parallel to each other. The long horizontal bar passes through the wall-side of one of the short horizontal bars and is fixed to the sleeve of the connecting fastener; the anti-slip fastener is connected to the side of the short horizontal bar away from the wall to prevent it from slipping out. A protective net is fixed to the long horizontal bar.
[0007] Based on the above technical solution, the pull-out wall-mounted mesh of this utility model can be further improved as follows:
[0008] The connector includes a fixed end and a movable end. The fixed end is fixedly connected to the sleeve, and the movable end is hinged to the fixed end.
[0009] Furthermore, an arc-shaped gap is provided between the fixed end and the movable end of the connector for support and fixation.
[0010] Furthermore, a fixing hole is provided on the side away from the hinge position at the connection between the movable end and the fixed end, and the sidewall of the fixing hole is provided with a thread.
[0011] Furthermore, fixing screws are inserted into the fixing holes of the movable end and the fixed end for fixation.
[0012] Furthermore, the inner diameter of the sleeve is set to 51mm, the length is set to 90mm, and the wall thickness of the sleeve is set to 4.2mm.
[0013] Furthermore, the length of the long crossbar is greater than the sum of the installation distances of the plurality of short crossbars.
[0014] Furthermore, the distance between the connecting fastener installed at the end of the short horizontal bar near the wall and the corresponding anti-slip fastener is the range of motion of the wall-mounted mesh. The movement of the short horizontal bar in the sleeve allows the wall-mounted mesh to be pulled out horizontally.
[0015] Furthermore, the inner diameter of the sleeve is slightly larger than the outer diameter of the short crossbar and the long crossbar.
[0016] Furthermore, the anti-slip fastener is a clamping component, and friction textures are provided on the inner wall that contacts the short crossbar.
[0017] Compared with existing technologies, the advantages of the pull-out wall-mounted mesh provided by this utility model are:
[0018] The connecting fastener mainly consists of a connector and a sleeve. The sleeve is cylindrical and fixedly connected to the connector on one side. The fixed end of the connector is connected to the sleeve, and the movable end is connected to the fixed end via a hinge. This structural design makes the wall-mounted mesh installation more stable while also providing a certain degree of flexibility, allowing the wall-mounted mesh to be pulled out horizontally.
[0019] Short crossbars are fixed parallel to the wall side using connecting fasteners. Their installation ensures the stability of the wall-mounted mesh and provides horizontal support. When installing connecting fasteners on the wall side, the sleeves are positioned parallel to ensure the fasteners' stability.
[0020] The long horizontal bar passes through the short horizontal bar and is fixed inside the sleeve. The side of the short horizontal bar away from the wall is equipped with an anti-slip fastener to prevent the connector from slipping out. The main function of the long horizontal bar is to provide support and secure it to the protective netting, thereby strengthening the overall structure of the netting against the wall.
[0021] The short crossbar is equipped with anti-slip fasteners on the side away from the wall. These fasteners prevent the crossbar from slipping out, ensuring structural safety. This design effectively prevents unnecessary displacement during the crossbar's movement.
[0022] An arc-shaped gap is provided between the fixed and movable ends of the connector to provide greater stability during support and fixation. A fixing hole is provided between the movable and fixed ends, and the sidewalls are threaded. This allows for securing both ends with screws, increasing the connection's strength. The sleeve's inner diameter, length, and wall thickness have specific requirements to ensure it fits both short and long crossbars in practical use.
[0023] The length of the long crossbars is greater than the total installation distance of the short crossbars to ensure sufficient span to support the entire structure.
[0024] The distance between the short crossbar and the anti-slip fastener determines the range of motion of the wall-mounted mesh. The pull-out function of the wall-mounted mesh can be achieved by moving the short crossbar within the sleeve.
[0025] The inner diameter of the sleeve is slightly larger than the outer diameter of the short and long crossbars. This ensures smooth movement of the crossbars and reduces friction.
[0026] The anti-slip fastener is a clamping component with friction texture on its inner wall, which enhances the contact force with the short crossbar and further ensures the stability of the structure.
[0027] This wall-mounted mesh is a stable and adjustable pull-out wall-mounted mesh system. It is adjustable and stable, and can move freely in the horizontal direction in actual use, while also ensuring the safety of the structure. Attached Figure Description

[0032] 10. Connecting fastener; 11. Connector; 12. Sleeve; 20. Short crossbar; 30. Anti-slip fastener; 40. Long crossbar. Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0034] like Figure 1-2 The diagram shows a schematic of a pull-out wall-mounted safety net provided by this utility model. The net includes a connecting fastener 10, short horizontal bars 20, anti-slip fasteners 30, and a long horizontal bar 40. The connecting fastener 10 includes a connector 11 and a sleeve 12. The sleeve 12 has a cylindrical structure, with one side fixedly connected to the connector 11. At least two short horizontal bars 20 are fixed parallel to each other on the side of the scaffolding closest to the wall via the connecting fasteners 10. The side of the short horizontal bar 20 closest to the wall has a connector 11, and the corresponding sleeves 12 are arranged parallel to each other. The long horizontal bar 40 passes through the sleeve 12 of the short horizontal bar 20, which is fixed to the wall side. The side of the short horizontal bar 20 away from the wall is connected to the anti-slip fastener 30 to prevent the short horizontal bar 20 from slipping out. A protective net is fixed to the long horizontal bar 40.
[0035] In the above technical solution, the connector 11 includes a fixed end and a movable end. The fixed end is fixedly connected to the sleeve 12, and the movable end is hinged to the fixed end.
[0036] Furthermore, in the above technical solution, an arc-shaped gap is provided between the fixed end and the movable end of the connector 11 for support and fixation.
[0037] Furthermore, in the above technical solution, a fixing hole is provided on the side away from the hinge position at the connection between the movable end and the fixed end, and the sidewall of the fixing hole is provided with a thread.
[0038] Furthermore, in the above technical solution, fixing screws are inserted into the fixing holes of the movable end and the fixed end for fixing.
[0039] Furthermore, in the above technical solution, the inner diameter of the sleeve 12 is set to 51mm, the length is set to 90mm, and the wall thickness of the sleeve 12 is set to 4.2mm.
[0040] Furthermore, in the above technical solution, the length of the long crossbar 40 is greater than the sum of the installation distances of the multiple short crossbars 20.
[0041] Furthermore, in the above technical solution, the distance between the connecting fastener 10 installed at the end of the short horizontal bar 20 near the wall and the corresponding anti-slip fastener 30 is the range of motion of the wall-mounted mesh. The movement of the short horizontal bar 20 in the sleeve 12 enables the wall-mounted mesh to be pulled out in the horizontal direction.
[0042] Furthermore, in the above technical solution, the inner diameter of the sleeve 12 is slightly larger than the outer diameter of the short crossbar 20 and the long crossbar 40.
[0043] Furthermore, in the above technical solution, the anti-slip fastener 30 is a clamping component, and friction texture is provided on the inner wall that contacts the short crossbar 20.
[0044] Example 1: On a construction site, connecting fasteners are fixed with screws, and the gap design between the movable and fixed ends allows for more flexible connections. The short horizontal bars are 1.5 meters long, and their ends are fixed to the wall of the construction area using connecting fasteners, adapting to the width of typical construction sites. Anti-slip fasteners prevent the mesh frame from loosening, ensuring safety during construction. The long horizontal bars are 2.5 meters long, ensuring they can span multiple short horizontal bars and firmly secure the protective mesh. This structural design is suitable for safety protection in temporary construction areas, allowing for adjustment of the mesh's range of motion against the wall as needed, ensuring the safety of items and personnel on the construction site.
[0045] Example 2: In large construction sites, connecting fasteners use larger sleeves (60mm inner diameter, 100mm length) to meet high-strength support requirements. Short horizontal bars are 2 meters long and are fixed to the site's perimeter wall or support frame using multiple connecting fasteners. Anti-slip fasteners effectively prevent the space frame from loosening due to external impacts during construction. Long horizontal bars are 4 meters long, ensuring they can support multiple short horizontal bars and cover a large area, forming a complete safety net. This design allows for flexible adjustment of the space frame's range according to the needs of different construction areas, ensuring the safety of personnel and equipment on the construction site.
[0046] Example 3: At the construction site, connecting fasteners are fixed by welding or high-strength screws to ensure the stability of the structure in extreme environments. The short crossbars, made of steel and 3 meters long, are suitable for supporting large construction fencing, providing stronger support. The anti-slip fasteners feature a high-friction design to ensure the firmness of the short crossbars and connection points, preventing loosening during construction. The long crossbars, 5 meters long, ensure they can span large areas of the construction site, stably supporting the protective netting. This structure is particularly suitable for temporary safety protection at construction sites, allowing for adjustments to the position and extent of the netting according to the construction progress, preventing personnel or objects from falling during construction, and also possessing wind resistance to adapt to the complex construction environment.
[0047] Specifically, the principle of this utility model is as follows: In use, firstly, the fixed end of the connecting fastener is welded to the sleeve to ensure that the movable end of the connecting fastener can move flexibly. The connecting fastener 10 and the short horizontal bar 20 are installed on one side of the outer frame, and the anti-slip fastener 30 is installed at the rear end of the short horizontal bar 20 to prevent it from slipping out. The connecting fastener 10 and the short horizontal bar 20 are installed on the other side of the outer frame, and the anti-slip fastener 30 is installed at the rear end of the short horizontal bar 20. The long horizontal bar passes through the wall-facing end of the short horizontal bar, ensuring it is fixed inside the sleeve of the connecting fastener; then the netting is hung. The movement of the short horizontal bar allows the wall-facing netting to be pulled horizontally. By adjusting the movement of the short horizontal bar in the sleeve, the range of motion of the wall-facing netting can be made larger or smaller, depending on the usage requirements. The design of the anti-slip fastener ensures that the connecting fastener will not slip out, increasing the safety of the entire system. The friction texture design of the anti-slip fastener enhances the contact force with the short horizontal bar, further stabilizing the structure.
