Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an edge protection device for stairs. Background Technology

[0002] Staircases in residential buildings are important vertical transportation facilities within the building, used to connect different floors and ensure that residents can move between floors safely and conveniently.

[0003] However, in actual construction, the formal stair railings can only be measured and cut after the tiling or plastering of the stair treads is completed. This results in the stairwell being without edge protection for at least a month, making it easy for construction workers to fall from the edge when passing through, posing a significant safety hazard that needs to be improved. Utility Model Content

[0011] In a preferred embodiment, the present invention can be further configured such that: the pressure strip includes a middle rod and a pair of end rods, the two ends of the middle rod are used to insert the end rods, and the outer side of the end rods is provided with ear plates.

[0012] In a preferred embodiment, the present invention can be further configured such that: a locking ring is provided on the wire rope, and pull ropes are provided on both sides of the protective net.

[0013] In a preferred embodiment, the present invention can be further configured such that a light strip is provided on the steel wire rope.

[0014] In a preferred embodiment, the present invention can be further configured such that a clip for holding the steel wire rope is provided on the back side of the light strip.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By installing a safety net between the top and bottom staircases as a temporary protective device, construction workers are prevented from falling and construction safety is ensured. At the same time, the installation process of the protective device is quick and convenient, which can improve construction efficiency. Furthermore, the protective device can be disassembled and reused, which improves its practicality.

[0017] 2. By setting a tightening clamp on the pressure bar that can limit and adjust the tension of the wire rope, the wire rope is always kept taut to prevent swaying and achieve stable protection;

[0018] 3. By installing easy-to-install light strips on the steel wire rope, lighting is provided for walking in the stairwell, while also serving as a warning and ensuring construction safety. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a staircase edge protection device includes a pair of steel wire ropes 1, a protective net 2, and a pressure strip 3.

[0026] like Figure 2 , Figure 3As shown, a pair of steel wire ropes 1 are arranged parallel to each other and vertically positioned between the top and bottom staircases. The protective netting 2 is made of nylon and is positioned between the pair of steel wire ropes 1. Locking rings 11 are installed on the steel wire ropes 1, and pull ropes 21 are installed on both sides of the protective netting 2 to facilitate rapid installation.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, the pressure strip 3 is installed at an angle on the outside of the stair tread and presses against the protective net 2. Both ends of the pressure strip 3 are provided with grooves 31 for the steel wire rope 1 to be embedded, so as to limit the steel wire rope 1, prevent the steel wire rope 1 from swaying, and achieve stable protection.

[0028] When it is necessary to set up the protective device, the top of the steel wire rope 1 is fixed to both sides of the top floor staircase with expansion bolts, allowing the steel wire rope 1 to hang down naturally and pass over all the staircases before being fixed to the bottom floor staircase with expansion bolts.

[0029] Then, the protective net 2 is unfolded and hangs down naturally from top to bottom. Using the cooperation of the pull rope 21 and the locking ring 11, the protective net 2 is fixed to the steel wire rope 1. At this time, the protective net 2 covers the side of each staircase away from the wall, achieving initial protection.

[0030] Finally, the pressure strip 3 is fastened to the side wall of the stair slab, and the wire rope 1 is embedded in the groove 31 on the pressure strip 3 to limit the position of the wire rope 1. Then, the pressure strip 3 is fixed to the stair slab with bolts or nail guns to achieve segmented fixing of the protective net 2 and ensure stable protection.

[0031] Therefore, by installing a safety net 2 between the top and bottom staircases as a temporary protective device, construction workers are prevented from falling and construction safety is ensured. At the same time, the installation process of the protective device is quick and convenient, which can improve construction efficiency. Furthermore, the protective device can be disassembled and reused, which improves its practicality.

[0032] like Figure 3 , Figure 4 As shown, a rotating shaft 32 is rotatably connected to the pressure bar 3, and a tightening clamp 33 is provided on the rotating shaft 32 within the groove 31. The tightening clamp 33 is U-shaped and is used to clamp the wire rope 1. A pawl 34 is provided on the outer wall of the rotating shaft 32, and a ratchet 35 that cooperates with the pawl 34 is provided on the pressure bar 3.

[0033] When the pressure strip 3 is fastened to the stair slab, the wire rope 1 is embedded in the groove 31 and held by the tightening clamp 33. At this time, the rotating shaft 32 can be rotated to drive the tightening clamp 33 to rotate, causing the wire rope 1 to twist and tighten the wire rope 1, ensuring that the wire rope 1 is always in a taut state, preventing swaying, and achieving stable protection.

[0034] Furthermore, during the rotation of the shaft 32, the shaft 32 drives the pawl 34 to move synchronously. At this time, with the cooperation of the pawl 34 and the ratchet 35, the shaft 32 is fixed, and the tension of the wire rope 1 is quickly adjusted.

[0035] like Figure 4 As shown, the pressure strip 3 includes a middle rod 36 and a pair of end rods 37. The two ends of the middle rod 36 are used to insert the end rods 37, and the outer side of the end rods 37 is provided with ear plates 38.

[0036] When designing staircases with varying spans, intermediate rods 36 of different lengths can be selected. These intermediate rods 36 can be made of timber or planks, readily available materials. Both ends of the intermediate rod 36 are directly inserted into the end rods 37, and bolts are used to secure the ear plates 38 on the end rods 37. Finally, a nail gun is used to secure the intermediate rod 36. When disassembly is required, only the end rods 37 need to be recycled; the intermediate rods 36 can be discarded for future reuse.

[0037] like Figure 3 As shown, a light strip 4 is installed on the steel wire rope 1 to provide lighting for walking in the stairwell, and also to serve as a warning to ensure construction safety. A clip 41 is provided on the back side of the light strip 4 to hold the steel wire rope 1, so as to facilitate the installation and removal of the light strip 4, making it convenient for deployment and storage.

[0038] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
