Description

Technical Field

[0001] This utility model relates to the field of roof construction, and more specifically, to a safety net hanger for truss roof construction. Background Technology

[0002] During roof construction, workers will perform various operations on the tubular trusses. Due to the spacing and height difference between adjacent tubular trusses, safety nets must be installed to ensure the safety of construction personnel. Safety nets effectively prevent workers from accidentally falling from heights, creating a safe working environment and reducing the risks of working at heights. Simultaneously, they can intercept tools, materials, and other objects that may fall during construction, preventing them from injuring personnel and equipment below. This serves as a protection against falling objects, ensuring the safety of personnel and the normal operation of equipment on the construction site, and facilitating the smooth progress of tubular truss roof construction.

[0003] Currently, the common method for installing safety nets mainly relies on safety ropes for securing them. Typically, the safety net is only installed after the two tubular trusses are in place. During this process, workers must climb onto both trusses to establish a connection between the trusses and the safety net using safety ropes, thus positioning the net. Similarly, during dismantling, workers must climb onto the trusses to remove the net. This method of safety net installation and dismantling significantly increases the risk to workers, posing a high safety hazard. Furthermore, the complex and cumbersome process severely impacts work efficiency, greatly reducing its practicality. Utility Model Content

[0024] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0025] Please refer to Figures 1-7 This application provides a safety net 200 hanger for roof construction of a tubular truss 100, comprising: a positioning assembly including a connecting channel steel 300 and a U-bolt 500, wherein the connecting channel steel 300 is arranged perpendicular to the chord direction of the tubular truss 100 and passes through the gaps in the tubular truss 100, and the U-bolt 500 is used to establish a connection between the connecting channel steel 300 and the web members of the tubular truss 100; wherein there are multiple positioning assemblies, which are arranged sequentially at intervals along the extension direction of the chord of the tubular truss 100; a rolling assembly including a connecting rail 400 and multiple rolling blocks 600, wherein the connecting rail 400 is arranged along the extension direction of the chord and is simultaneously connected to multiple connecting channel steels 300, and any of the rolling blocks 600 is rotatably disposed on the connecting rail 400; and a suspension hook 800 disposed on the rolling blocks 600; wherein any of the rolling blocks 600 is provided with the suspension hook 800.

[0026] During the roof construction of the tubular truss 100, the first step is to identify the two adjacent tubular trusses 100 to be installed. Then, the hangers of this application are installed on each tubular truss 100. Specifically, a cooperating positioning component, a rolling component, and a suspension hook 800 are assembled on each tubular truss 100. The positioning component ensures accurate installation of the hangers, the rolling component facilitates subsequent operations, and the suspension hook 800 bears the crucial load-bearing function. After the hangers are installed, the two tubular trusses 100 are hoisted to the roof and installed in place. During installation, it is essential that the suspension hooks 800 of the two tubular trusses 100 are in a relative position. This completes the installation of the hangers of this application. The installation of the safety net 200 is simple and efficient. Using external auxiliary tools such as struts, the safety net 200 is suspended from the corresponding suspension hooks 800 of the two tubular trusses 100, thus quickly completing the installation of the safety net 200. This installation method significantly reduces installation time, and construction workers do not need to climb onto the truss 100 to work, greatly reducing construction risks, significantly improving safety, and significantly enhancing the practicality of the entire construction plan.

[0027] Furthermore, since the rolling block 600 can slide on the connecting rail 400, the suspension position of the suspension hook 800 can be adjusted. The connecting rail 400 has a rolling groove, and the rolling block 600 is provided with a roller. The roller and the rolling groove roll into each other to achieve rolling engagement between the rolling block 600 and the connecting rail 400.

[0028] In a preferred embodiment, any of the aforementioned connecting channel steel 300 and the aforementioned connecting rail 400 are detachably connected by a bolt group.

[0029] In the above embodiments, during the installation process, construction workers can easily tighten the bolts using conventional tools to precisely install the connecting channel steel 300 into the designated position on the connecting rail 400. The operation is simple and flexible, effectively improving installation efficiency. Conversely, by loosening the bolt group, the connecting channel steel 300 can be easily removed from the connecting rail 400 without the need for complex removal processes and large equipment, greatly saving labor and time costs.

[0030] In a preferred embodiment, the suspension hook 800 is provided with a connecting plate 700, and the connecting plate 700 and the rolling block 600 are detachably connected by a bolt group.

[0031] In the above embodiments, during later maintenance and replacement, if the suspension hook 800 is damaged, worn, or needs to be adjusted, it can be easily removed from the rolling block 600 simply by unscrewing the bolt assembly, allowing for repair, replacement, or reinstallation, effectively saving maintenance time and costs. Furthermore, the bolt assembly connection is highly stable, ensuring that the suspension hook 800 and rolling block 600 remain tightly connected when the safety net 200 is subjected to external impacts such as personnel operations or falling objects, guaranteeing the reliability of the safety net 200's suspension and providing a solid guarantee for the safety of the truss 100 roof construction.

[0032] In a preferred embodiment, any of the aforementioned connecting channel steel 300 is connected to the aforementioned pipe truss 100 by two sets of the aforementioned U-bolts 500.

[0033] In the above embodiment, during installation, construction workers can easily use the shape of the U-bolts 500 to initially position the connecting channel steel 300 and the pipe truss 100, and then complete the connection by tightening the nuts. The operation is simple and efficient, greatly shortening the installation time. The two sets of U-bolts 500 apply tightening forces to the connecting channel steel 300 and the pipe truss 100 from different directions, which can effectively distribute the force and enhance the firmness of the connection between the two.

[0034] In a preferred embodiment, there are two rolling components, which are respectively disposed on both sides of the tubular truss 100.

[0035] In the above embodiment, safety nets can be conveniently installed on both sides of the tubular truss 100 simultaneously, providing comprehensive coverage of the construction area and offering double the protection for construction personnel, greatly reducing the risk of falls from heights. Installation work on both sides can be carried out simultaneously without interference, significantly improving construction efficiency and ensuring the safety of roof construction on the tubular truss 100.

[0036] As a preferred embodiment, the U-bolt 500 is also provided with a washer.

[0037] In the above embodiments, during tightening, the shim can increase the stress-bearing area of ​​the contact points between the U-bolt and the connecting channel steel 300 and the tubular truss 100. When the nut is tightened and pressure is applied, the pressure can be more evenly distributed to the contact surface through the shim, avoiding local damage to the connecting channel steel 300 or the tubular truss 100 due to concentrated stress, thereby effectively protecting the surface integrity of the connected components and extending their service life.

[0038] In a preferred embodiment, the connecting rail 400 is located on the underside of any of the connecting channel steels 300.

[0039] In the above embodiment, the connecting track 400 is located below the connecting channel steel 300, so that the connecting channel steel 300 will not obstruct the suspension hook 800, making it easier to suspend the safety net 200, which is practical.
