Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a fall prevention device for the removal of old doors and windows in high-rise buildings. Background Technology

[0002] During the demolition of old windows in high-rise buildings, there is often a risk of debris falling from heights, which not only threatens pedestrians on the ground but also poses a safety hazard to construction workers. Traditional demolition methods usually rely on manual demolition, and existing protective measures pose significant safety risks to the dismantling of old windows.

[0003] Currently, Chinese patent publication number CN113006506A discloses a detachable fall protection device and its installation method for multi-story residential buildings. The device includes at least two sets of parallel and symmetrically arranged foldable telescopic rods, each comprising a vertical support rod and a horizontal telescopic rod. One end of the vertical support rod is movably connected to one end of the horizontal telescopic rod, and the other end of the vertical support rod is movably connected to the other end of the horizontal telescopic rod via a hydraulic diagonal brace. A reel box for storing the interception net is provided between the two vertical support rods. This discloses existing fall protection devices. Existing closure methods typically use scaffolding and protective nets to achieve closed dismantling. However, for some high-rise buildings above the 30th floor that require individual dismantling, the cost of erecting scaffolding is high.

[0004] Chinese Patent Publication No. CN221168800U discloses an edge protection device for facilitating the installation and removal of window openings. The device includes a galvanized steel pipe located in the middle of a component, with a continuous groove on its outer surface and a roller inside. Two adjustable quick-release support adjusters are symmetrically arranged on both sides of the galvanized steel pipe, each including a U-shaped portion and a cylindrical portion. One end of a dense-mesh safety net is wound onto the roller of the galvanized steel pipe. The dense-mesh safety net is a rectangular soft net, and it is installed directly. However, due to the structure of old doors and windows, this safety net is difficult to install on the exterior wall. Furthermore, the safety net has large gaps at the corners. In some cases, the safety net is laid flat on the outside of the window during disassembly. Because of strong winds on high floors, sand and window parts can easily fall out and be blown far away during disassembly, making the flat-laid safety net insufficient to guarantee safety during disassembly. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a fall prevention device for the demolition of old doors and windows in high-rise buildings, so as to solve the above problems of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fall prevention device for the removal of old doors and windows in high-rise buildings, comprising a wall and a wall opening located in the middle of the wall, the wall having an inner wall surface and an outer wall surface, and further comprising clamps detachably mounted on the wall and located around the wall opening, and a protective cover for connecting with the clamps, the protective cover covering the outer wall surface of the wall opening.

[0007] Furthermore, the clamp includes a clamping block, an adjusting block located on one side of the clamping block, a fixing block located on the other side of the clamping block, and a screw screwed into the adjusting block. The adjusting block and the screw screw are located on one side of the inner wall surface.

[0008] Furthermore, the top of the protective cover is sewn with a hanging rope or a first hook, and the side of the fixing block away from the adjusting block is provided with a connecting part for connecting and fixing with the hanging rope or the first hook.

[0009] Furthermore, the protective cover has a hardened area at the bottom of the wall opening.

[0010] Furthermore, the protective cover has an adhesive area around the wall opening.

[0011] Furthermore, the clamps located horizontally at the bottom of the wall opening are lower clamps. The bottom of the protective cover is flipped and attached to the outer wall surface to form a lower contact surface. The lower clamp is located on the side close to the wall, and the lower contact surface is located between the wall and the fixing block.

[0012] Furthermore, the clamps located horizontally at the top of the wall opening are upper clamps, and the top of the protective cover is connected to the upper clamps.

[0013] Furthermore, the protective cover is a plastic film or a protective net.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0015] This anti-fall device for the removal of old doors and windows in high-rise buildings uses a combination of a protective cover and clamps. Before removing the old doors and windows, the clamps are first held around the window. After that, the protective cover is connected to the clamps. At this point, the protective cover and clamps are connected and wrap around the window. The protective cover blocks the wall opening. This installation method is simple and quick. At the same time, because the clamps hold the window around, they can surround and seal the wall opening. If door and window frame parts accidentally fall, they will be collected and blocked by the protective cover. This avoids the problems of complicated installation of existing protective devices, strong winds on high floors, and sand and gravel falling out during dismantling. Attached Figure Description

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to Figures 1 to 11 This embodiment provides a fall prevention device for the removal of old doors and windows in high-rise buildings, including a wall 100 and a wall opening 200 located in the middle of the wall 100. The wall 100 has an inner wall surface 10a and an outer wall surface 10b.

[0029] It also includes a clamp 1 detachably mounted on the wall 100 and located around the wall opening 200, and a protective cover 2 for connecting to the clamp 1, the protective cover 2 covering the outer wall surface 10b of the wall opening 200.

[0030] Before removing old doors and windows on high-rise buildings, clamp 1 is first clamped around the window. After that, the protective cover 2 is connected to clamp 1. At this time, the protective cover 2 and clamp 1 are connected to wrap the window. The protective cover 2 blocks the wall opening 200. At the same time, since clamp 1 clamps around the window, if the door and window frame parts accidentally fall, they will be collected and blocked by the protective cover 2, avoiding the problem of high risk of accidental falling when removing old doors and windows on high floors.

[0031] The clamp 1 includes a clamping block 101, an adjusting block 102 located on one side of the clamping block 101, a fixing block 103 located on the other side of the clamping block 101, and a screw 104 screwed into the adjusting block 102. The adjusting block 102 and the screw 104 are located on one side of the inner wall surface 10a.

[0032] The inner wall surface 10a of the wall 100 refers to the wall located inside the room, and the outer wall surface 10b of the wall 100 refers to the wall located on the outdoor side. With the screw 104 and the adjusting block 102 on one side of the inner wall surface 10a of the wall 100, the adjusting blocks 102 and the fixing blocks 103 on the left and right sides of the locking block are clamped on the window of the wall 100. Then, the screw 104 is rotated and tightened, and the screw 104 and the fixing block 103 will be tightly clamped on the wall 100.

[0033] The clamps 1 arranged horizontally at the top of the wall opening 200 of the wall 100 are upper clamping fixtures 1b, and the top of the protective cover 2 is connected to the upper clamping fixtures 1b.

[0034] The top of the protective cover 2 is sewn with a hanging rope 105 or a first hook 106, and the upper clamping prop 1b has a connecting part on the side of the built-in fixing block 103 away from the adjusting block 102 for connecting and fixing with the hanging rope 105 or the first hook 106.

[0035] The connecting part is a second hook 108 on the side of the upper clamping prop 1b with a built-in fixing block 103 away from the adjusting block 102. The connecting part can also be a round hole 109 on the fixing block 103, through which the hanging rope 105 or the first hook 106 is directly passed for fixation. The top of the protective cover 2 may not have a hanging rope 105 or the first hook 106, but may have a ring hole 107 for hanging in the second hook 108. Alternatively, the top of the protective cover 2 may have a hanging rope 105 or the first hook 106, through which the hanging rope 105 is passed for fixation, or the first hook 106 and the second hook 108 can be used together for fixation.

[0036] The connection method between the protective cover and the clamp's round hole via the hanging rope can be referenced. Figure 2 The method by which the protective cover is fixed to the first hook of the clamp through the annular hole can be referred to Figure 3 The connection method between the second hook on the protective cover and the first hook on the clamp can be referred to Figure 4 .

[0037] The optimal usage configuration is as follows: the top of the protective cover 2 is equipped with a first hook 106, and the fixing block 103 on the right side of the clamp 1 houses a second hook 108. The first hook 106 and the second hook 108 fit together securely, allowing for quick and convenient installation. The first hook 106 and the second hook 108 are preferably carabiners or quick-release buckles, incorporating a blocking bar and a spring for rotating the blocking bar to stop the hook portion. This structure offers good safety and is a common, existing component, so it will not be described in detail here.

[0038] The protective cover 2 has a hardened area 3 at the bottom of the wall opening 200. The protective cover 2 in the hardened area 3 can be made of a thickened, folded, rigid material, or filled with materials such as plastic, iron sheet, fabric with higher hardness or thickness, heat-fused hardened protective cover 2 in this area, or other existing hardening technologies. When the clamp 1 clamps the left and right sides and the middle of the protective cover, the bottom edge of the protective cover can be attached to the outer wall surface together, which can reduce the gap between the protective cover 2 and the non-contact area of ​​the clamp 1 at the bottom of the wall opening 200, and prevent sand and gravel particles from falling from the gap when dismantling old doors and windows. The hardened area 3 can also be set around the protective cover 2 to strengthen the edge of the protective cover.

[0039] The protective cover 2 has an adhesive area 4 around the wall opening 200. The adhesive area 4 around the wall opening 200 can be used to apply adhesive, which can be structural adhesive, acrylic pressure-sensitive adhesive or other materials. This can make the protective cover 2 fit the wall more tightly and prevent small sand and gravel particles from falling into the gaps of the protective cover 2 during disassembly and causing danger.

[0040] The clamps 1 arranged horizontally at the bottom of the wall opening 200 of the wall 100 are lower clamping tools 1a. The bottom of the protective cover 2 is flipped and attached to the outer wall surface 10b of the wall 100 to form a lower attachment surface 2a. The lower clamping tool 1a is close to the side of the wall 100, and the lower attachment surface 2a is located between the wall 100 and the fixing block 103.

[0041] You can refer to this. Figure 2 In this state, flip the bottom of the protective cover 2 upwards 180 degrees and attach it to the wall 100. Then, you can use the lower clamp tool 1a to clamp it directly, or... Figure 5 The bottom of the protective cover 2 is flipped over and then folded in half to adhere to the outer wall surface 10b of the wall 100.

[0042] The clamping method on both sides of the wall 100 in the horizontal direction can also be to use the lower clamping tool 1a to clamp the protective cover 2.

[0043] The protective cover 2 is a plastic film or protective net, which provides good protection. When dismantling old doors and windows, the protective cover can catch small sand particles or old window parts to prevent them from falling from high-rise buildings and causing danger.

[0044] The fixing block 103 has a recessed groove 103a on the side near the wall 100. The fixing block is provided with a fixing device 5 for fixing the protective cover through the fixing block. The fixing device 5 includes a column 51, an inner hole 52 inside the column 51, an adjusting column 53 slidably disposed in the inner hole 52 inside the column 51, an outer ring hole 54 on one side of the column 51, an L-shaped plate 55 hinged to the outer ring hole 54 of the column 51, an inner ring hole 56 on one side of the adjusting column 53, a spring 57 on the left side of the adjusting column 53, an external thread 58 on the outside of the column 51, an adjusting knob 59 screwed on the outside of the column 51, and a fixing ring 50 fixed on the side of the column 51 away from the L-shaped plate 55. The L-shaped plate 55 is in contact with the inner ring hole 56 of the adjusting column 53.

[0045] In use, first press the hardened area at the bottom of the protective cover into the recessed groove 103a of the column 51, then press the adjusting column 53. At this time, the adjusting column 53 moves towards the spring 57, and the inner ring hole 56 of the adjusting column 53 pushes the L-shaped plate 55 to rotate and fit against the outside of the adjusting column 53. Then, pass the column 51 through the fixing block and the protective cover. After completion, release the adjusting column 53. Under the force of the spring 57, the adjusting column 53 moves towards the fixing ring 50. During the movement of the adjusting column 53, it drives the L-shaped plate 55 to rotate towards the outer ring hole 54, and the L-shaped plate 55 unfolds outward. At this time, rotate the adjusting knob 59 to lock the protective cover and the fixing block between the L-shaped plate 55 and the adjusting knob 59. After completion, remove the fixing ring. A safety rope is tied to the end of the fixing ring 50 to secure it to the ground nail inside the wall. Compared to traditional fastener fixation, where bolts or nuts may loosen after installation and pose a risk of falling off the protective cover, and where a safety rope needs to be tied to the fixing block to prevent accidental drop during use, the adjusting knob 59 of this fixing device is located outside the column 51 and cannot fall out, ensuring good safety during use. Furthermore, by tying a safety rope to the fixing ring 50, the protective cover, the fixing device itself, and the fixing block can be held together simultaneously, eliminating the need for additional safety ropes. Disassembly of the fixing device also does not require a wrench or other auxiliary tools, preventing tools from falling and further reducing the risk of use.
