Description
Technical Field
[0001] This utility model relates to the field of construction safety equipment technology, specifically a protective net for building engineering. Background Technology
[0002] Construction safety nets are widely used safety protection materials and facilities during construction. They are typically made from high-density polyethylene, polypropylene, or polyester fibers through weaving, stretching, or dip coating processes. Some metal safety nets also use galvanized steel wire to enhance strength and corrosion resistance. They are mainly erected or suspended on building facades, the outside of scaffolding, floor edges, and around openings in hazardous areas. Their core function is to prevent construction workers, tools, or building materials from falling, while also intercepting falling objects to avoid injury to personnel and equipment on the ground. Some dustproof safety nets also have the auxiliary function of suppressing dust dispersion. They are fundamental protective equipment for ensuring the safety of personnel and maintaining order at construction sites.
[0003] In practical applications, existing scaffolding safety net installation structures suffer from insufficient stability due to traditional fixing methods. These structures often rely on single clips or bolts, making them prone to loosening and detachment due to construction vibrations or accidental contact. Furthermore, they lack anti-accidental contact locking designs, posing significant safety hazards. Their adaptability is also poor; they cannot flexibly adjust installation spacing to accommodate scaffolding steel poles of varying lengths, limiting their versatility. In addition, the traditional safety net's unfolding and folding structures are poorly designed, with cumbersome procedures. Unfolding is difficult due to slow and rapid stretching, and folding is challenging, increasing the workload for construction workers and increasing the risk of damage due to haphazard stacking, thus shortening its lifespan.

[0016] This protective netting for construction projects features a designed safety mechanism. By adjusting the positioning components, the netting can be quickly pulled out to meet immediate construction protection needs. After use, the netting can be easily rolled up, effectively reducing storage volume and facilitating on-site storage and turnover. This avoids damage or space occupation caused by haphazardly stacking the netting, and reduces subsequent maintenance and management costs. Attached Figure Description

The surface of the cross block 232 is slidably connected to the inside of the cross groove. A slot is opened inside one end of the upper card seat 23. The surface of the positioning strip 256 is fixedly connected to the inner wall of the slot. A positioning hole is opened on the surface of the positioning strip 256.

[0023] Furthermore, a slot is opened inside the left end of the lower bracket 24, and one end of the surface of the L-shaped clip 257 is engaged with the inside of the slot. An arc groove is opened inside the top of the upper half buckle 21, and the surface of the clamping strip 28 is located inside the arc groove. By changing the different positions of the locking holes between the T-shaped rod 26 and the positioning strip 29, the installation of scaffolding steel poles 1 of different lengths can be adapted. In addition, when the upper half buckle 21 and the lower half buckle 22 are in contact with the scaffolding steel pole 1, the bolt 27 can be rotated to change the clamping force between the clamping strip 28 and the scaffolding steel pole 1, thereby further strengthening the clamping effect of the device on the scaffolding steel pole 1. Example
[0024] See Figures 1 to 10 Furthermore, based on Embodiment 1, the protective net mechanism 3 further includes a support frame 31, which is fixedly connected to the bottom of the positioning strip 29. A rotating shaft 32 is rotatably connected inside the support frame 31. Positioning discs 34 are fixedly connected to both ends of the rotating shaft 32. A protective net cover 33 is fixedly connected to the surface of the rotating shaft 32. A stand 35 is fixedly connected to both ends of the surface of the support frame 31. A fourth spring 36 is fixedly connected inside the stand 35. A ring 37 is fixedly connected to one end of the fourth spring 36. A lever 39 is rotatably connected to the surface of the ring 37. A vertical rod 38 is fixedly connected inside the ring 37. The bottom end of the vertical rod 38 is fixedly connected to the inside of the stand 35. An E-shaped groove is opened on the front of the stand 35, and the surface of the lever 39 matches the inside of the E-shaped groove.
[0025] Furthermore, an annular hole is formed on the surface of the positioning disc 34, and the surface of the vertical rod 38 matches the inside of the annular hole. A vertical groove is formed inside the base 35, and the surface of the lever 39 is movably connected to the inside of the vertical groove. Through holes are formed at the upper and lower ends of the base 35, and the surface of the vertical rod 38 passes through the through holes formed at the upper and lower ends of the base 35. The vertical rod 38 is detached from the inside of the positioning disc 34, so the protective net cover 33 can be pulled to extend it for use. When storing, it can be rolled up, so that the protective net can be unfolded when in use and stored conveniently when not in use.
[0026] In actual operation, when using the protective net, it needs to be installed on the steel pipes of the construction scaffold. At this time, the upper half-lock 21 and the lower half-lock 22 are fitted onto the scaffold steel pole 1. During this process, the upper bracket 23 and the lower bracket 24 are brought into contact, and the L-shaped locking strip 257 on the upper bracket 23 is inserted into the slot inside the lower bracket 24, thus limiting and fixing the upper bracket 23 and the lower bracket 24. Furthermore, to prevent the L-shaped locking strip 257 from accidentally disengaging from the lower bracket 24 due to accidental contact with the cross block 232, after the L-shaped locking strip 257 is inserted into the lower bracket 24, the guide seat 25 inside the upper bracket 23... The clamping rod 253 is inserted into the positioning hole on the positioning strip 256, thereby preventing accidental contact with the L-shaped clamping strip 257 that could cause the upper clamping seat 23 to detach from the lower clamping seat 24. In addition, when it is necessary to adjust the distance between the upper half buckle 21 and the lower half buckle 22 according to the length of the scaffolding steel pole 1, it is only necessary to change the different positions of the clamping holes between the T-shaped rod 26 and the positioning strip 29 to adapt to the installation of scaffolding steel poles 1 of different lengths. Furthermore, when the upper half buckle 21 and the lower half buckle 22 are in contact with the scaffolding steel pole 1, the bolt 27 can be rotated to change the clamping force between the clamping strip 28 and the scaffolding steel pole 1, thereby further strengthening the clamping effect of the device on the scaffolding steel pole 1. When the protective net cover 33 is unfolded, simply move the lever 39 to different positions inside the E-shaped groove of the stand 35, thereby disengaging the vertical rod 38 from the positioning disc 34, and then pull the protective net cover 33 to extend it. When storing, it can be rolled up, so it can be unfolded when the protective net is in use and conveniently stored when not in use.
