Description

Technical Field

[0001] This invention relates to the field of safety protection technology, and in particular to a fall prevention device for a steel structure skylight opening. Background Technology

[0002] Glass skylights are a common design structure in modern large-scale buildings. Skylights can improve the lighting inside the building, but when the skylight is open, external objects can fall into the building. Previously, some people installed steel mesh on the skylight to prevent objects from falling into the building. However, the steel mesh is installed close to the skylight, which reduces the ventilation of the skylight. Moreover, the steel mesh cannot be removed. After the skylight is open for a long time, a lot of garbage will accumulate on the steel mesh, which will affect the closure of the skylight. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a fall prevention device for steel structure skylight openings.

[0004] The present invention provides a fall prevention device for steel structure skylight openings, which adopts the following technical solution:

[0005] A fall prevention device for a steel structure skylight opening includes a supporting steel frame and a movable and detachable supporting net.

[0006] The supporting steel frame is installed on one side of the skylight opening, and the supporting netting is movably connected to the lower end of the supporting steel frame.

[0007] By adopting the above technical solution, the supporting steel frame lowers the supporting netting so that it is not tightly attached to the skylight. This allows air to enter the house not only through the supporting netting but also to diffuse into the house from both sides of the supporting steel frame, increasing ventilation. The supporting netting can be removed from the supporting steel frame. When an object falls onto the netting, it can be removed to clear the object, effectively preventing the accumulation of objects that could make closing the skylight difficult.

[0008] Preferably, the supporting steel frame is an "I"-shaped steel frame, and the supporting mesh is connected with a beam tie member. The beam tie member is a "U"-shaped member, and the horizontal steel below the "I" of the supporting steel frame is inserted into the beam tie member.

[0009] By adopting the above technical solution, the horizontal steel below the "I" of the supporting steel frame is inserted into the inside of the clamping beam tie member. It can be inserted and then pulled out, which means that the clamping beam tie member can be moved and disassembled on the supporting steel frame.

[0010] Preferably, the tie beam is a detachable first component and a second component, which are connected by bolts. The first component and the second component surround the horizontal steel below the "I" shape of the supporting steel frame.

[0011] By adopting the above technical solution, the phenomenon of the supporting steel frame encountering obstacles or being unable to be inserted or pulled out when being inserted into the beam tie member is avoided. The beam tie member is set as two components, which are connected by bolts. If it cannot be pulled out, the beam tie member can be disassembled and removed.

[0012] Preferably, a tie wire rope is used to connect the beam tie member and the supporting net.

[0013] By adopting the above technical solution, the support netting can be suspended around its perimeter by setting up tie wire ropes, and the support netting can be held in place by the tie wire ropes.

[0014] Preferably, the supporting netting includes a protective frame and a protective soft net, wherein the mesh density of the protective soft net is higher than 14 mesh.

[0015] By adopting the above technical solutions, the ventilation of the protective soft net is stronger than that of the steel net. The mesh density of the protective soft net is higher than 14 meshes, which avoids the mesh being too large and unable to catch small objects when they fall in, thus failing to play a safety role.

[0016] Preferably, the protective frame includes a square support frame, horizontal keels and vertical keels. The square support frame is connected to a tie wire rope. Multiple horizontal keels are provided and placed horizontally in the middle of the square support frame. Multiple vertical keels are provided and placed perpendicular to the horizontal keels on the same plane.

[0017] By adopting the above technical solution, the protective soft net is easily torn by the weight when it is hit by a large object. Therefore, multiple horizontal and vertical keels are installed under the protective soft net to provide support. When a heavy object falls, the horizontal and vertical keels will provide support.

[0018] Preferably, the square support frame is provided with a rotating shaft, the rotating shaft is equipped with a handle, and the tie wire rope is wound around the rotating shaft.

[0019] By adopting the above technical solution, the tie steel wire rope can be pulled up or lowered by rotating the shaft, thereby pulling up or lowering the support net. After being lowered, the wind can enter the room from above the support net to a greater extent.

[0020] Preferably, the square support frame is provided with a pin, the pin is located on one side of the rotating shaft, and the rotating shaft is provided with a plurality of pin holes, the pin being able to be inserted into the pin holes.

[0021] By adopting the above technical solution, the rotating shaft can be fixed by inserting the pin into the pin hole of the rotating shaft, thereby fixing the height of the support net.

[0022] Preferably, the end of the handle away from the pivot is provided with a soft pad.

[0023] By adopting the above technical solution, a soft pad is provided on the handle, making the grip more comfortable when holding the handle.

[0024] Preferably, there are two rotating shafts, which are symmetrically distributed at both ends of the square support frame. Each of the two rotating shafts is provided with a gear in the circumferential direction, and the gears on the two rotating shafts are connected by a chain.

[0025] By adopting the above technical solution, the two rotating shafts rotate simultaneously, allowing the tie steel wire ropes on both sides to wind around synchronously, thus enabling the supporting net to move up and down in a balanced manner.

[0026] In summary, the present invention has the following beneficial technical effects:

[0027] 1. By lowering the supporting steel frame and not placing it tightly against the skylight, air can enter the house not only through the supporting netting but also diffuse into the house from both sides of the supporting steel frame, increasing ventilation. The supporting netting can be removed from the supporting steel frame. When objects fall onto the netting, it can be removed to clear the debris, effectively preventing the accumulation of objects that could make it difficult to close the skylight.

[0028] 2. To avoid obstruction or inability to insert or remove the supporting steel frame from the beam tie member, the beam tie member is configured as two components connected by bolts. If it cannot be removed, the beam tie member can be disassembled and removed.

[0029] 3. Protective soft netting is easily torn by the force of falling large objects. Therefore, multiple horizontal and vertical keels are installed below the protective soft netting to provide support. When heavy objects fall, the horizontal and vertical keels will provide support.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] This invention discloses a fall prevention device for a steel structure skylight opening. (Refer to...) Figure 1 The fall arrestor includes a supporting steel frame 1 and a movable and detachable supporting net 2.

[0039] The supporting steel frame 1 consists of two "I" shaped steel frames. The upper crossbeams are bolted to both sides of the skylight opening, installed in parallel, and hung upside down below the skylight. The supporting netting 2 is movably connected to the lower end of the supporting steel frame 1.

[0040] The supporting netting 2 is connected to a beam tie member 3, which is a concave shape. The horizontal steel below the "I" shape of the supporting steel frame 1 is inserted into the beam tie member 3. This allows the supporting steel frame 1 to be inserted and then pulled out, meaning the beam tie member 3 can be moved and disassembled on the supporting steel frame 1.

[0041] Reference Figure 2 However, it is possible that there may be a small amount of blockage in the tie beam 3 or that the insertion part of the support steel frame 1 may be bent, making it impossible to pull out or insert. In this case, the tie beam 3 can be made into a detachable first component 4 and a second component 5. The first component 4 is in the shape of "「" and the second component 5 is in the shape of an inverted "L". The two are connected by bolts. The bolts can be unscrewed and the first component 4 and the second component 5 can be separated to remove the support netting 2.

[0042] Reference Figure 3 The supporting netting 2 includes a protective frame 7 and a protective soft net 8, wherein the protective soft net 8 is a screen-type soft net with a mesh density higher than 14 meshes. The protective soft net 8 has better air permeability than steel mesh, and the mesh density of the protective soft net 8 is higher than 14 meshes to avoid the mesh being too large, which would prevent small objects from falling in and failing to provide a safety function.

[0043] Reference Figure 4 The protective frame 7 includes a square support frame 9, horizontal keels and vertical keels. The square support frame 9 is connected to the tie wire rope 6. There are multiple horizontal keels, which are placed horizontally in the middle of the square support frame 9. There are multiple vertical keels, which are placed perpendicular to the horizontal keels on the same plane.

[0044] The protective soft net 8 is easily torn by the force of a large object falling on it. Therefore, multiple horizontal and vertical keels are installed below the protective soft net 8 to provide support when a heavy object falls on it.

[0045] A tie wire rope 6 connects the beam tie member 3 and the support net 2. The tie wire rope 6 can be used to suspend the support net 2 from all sides.

[0046] Reference Figure 5 A rotating shaft 10 is installed inside the square support frame 9, and a handle 11 is installed on the rotating shaft 10. A steel wire rope 6 is wound around the rotating shaft 10. A pin 12 is also provided on the square support frame 9, located on one side of the rotating shaft 10. The rotating shaft 10 has multiple pin holes 13, into which the pin 12 can be inserted. There are two rotating shafts 10, symmetrically distributed at both ends of the square support frame 9. Each rotating shaft 10 has a circumferentially arranged gear 15, and the gears 15 on the two rotating shafts 10 are connected by a chain 16.

[0047] The tie steel wire rope 6 can be pulled up or down by rotating the pivot 10, thereby raising or lowering the supporting netting 2. When lowered, it allows more wind to enter the room from above the supporting netting 2. Rotating the pivot 10 to a suitable angle and inserting the pin 12 into the pin hole 13 of the pivot 10 fixes the pivot 10, thus fixing the height of the supporting netting 2. The chain 16 synchronizes the rotation of both pivots 10, causing the tie steel wire ropes 6 on both sides to wind synchronously, allowing the supporting netting 2 to move up and down in a balanced manner.

[0048] A soft pad 14 is provided at the end of the handle 11 away from the pivot 10. The soft pad 14 on the handle 11 makes the grip more comfortable when holding the handle 11.

[0049] The implementation principle of the anti-fall device for a steel structure skylight opening according to an embodiment of the present invention is as follows: The supporting steel frame 1 lowers the supporting netting 2 without it being tightly attached to the skylight. This allows wind to enter the house not only through the supporting netting 2 but also to diffuse into the house from both sides of the supporting steel frame 1, increasing ventilation. The supporting netting 2 can be removed from the supporting steel frame 1. When an object falls onto the supporting netting 2, it can be removed to clear the object, effectively preventing subsequent accumulation of objects and ensuring the skylight can be closed smoothly. Cranking the handle 11 lowers the tie steel wire rope 6, which is then inserted into the pin hole 13 via the pin shaft 12 for fixation, allowing the supporting netting 2 to be lowered to a suitable height.

[0050] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
