A wind-resistant climbing scaffold protective netting device

Abstract

This invention relates to a wind-resistant climbing scaffold protective net device. It involves installing a windproof net on the frame of the windproof climbing scaffold. At least one ventilator is installed on the protective net's ear plate, which can rotate under wind force. When strong winds blow, the ventilator rotates to form a pressure relief port with the protective net ear plate, guiding some of the wind force through the pressure relief port to release it, thereby reducing the pressure of the wind on the windproof climbing scaffold and alleviating the pressure exerted on the building by strong winds. Simultaneously, the pressure relief port reduces wind resistance, lowers the wind vibration effect, and improves the stability and safety of the building or equipment.

Description

Technical Field

[0001] This invention relates to a wind-resistant climbing scaffold protective netting device, belonging to the field of building construction technology. Background Technology

[0002] With the acceleration of urbanization, the number of high-rise buildings continues to grow. Wind-resistant climbing scaffolding, as a protective device that effectively reduces the impact of wind on buildings, improves their stability and safety, and prevents construction materials from falling from heights, is widely used in various construction sites. However, in the current use of wind-resistant climbing scaffolding, the conventional protective netting is made of perforated steel plates, assembled on the outside of the scaffolding to form a closed ring. Ventilation and pressure relief are achieved through the perforations. However, if the wind pressure is too high, the perforations alone cannot provide sufficient relief, easily leading to wind-induced vibration. This poses a significant challenge to the strength and stability of the entire wind-resistant climbing scaffolding, especially in areas with frequent strong winds, potentially causing it to break and fall from a height, resulting in serious safety accidents. Summary of the Invention

[0003] The purpose of this invention is to provide a wind-resistant climbing scaffolding protective net device to solve the problem that the windproof net cannot effectively relieve pressure through the mesh when the wind pressure is too high.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wind-resistant climbing scaffold protective net device, installed on the periphery of a building wall, the device comprising:

[0005] Frame;

[0006] At least two sets of connection structures are installed on both sides of the frame and connected to the wall. Each set of connection structures includes at least two guide components installed at intervals along the height direction on the wall, a guide rail installed on the frame, and a fall protection component formed on the guide rail and the guide components. The guide components are slidably connected to the guide rail, and the frame can move along the height direction.

[0007] A drive system is used to drive the frame to move along the length of the guide rail; and

[0008] Several protective nets are installed on the outside of the frame;

[0009] The protective net includes protective net ear plates and at least one ventilation component installed in the protective net ear plates. At least one of the ventilation components rotates under the action of wind force to form a pressure relief port between itself and the protective net ear plates.

[0010] Furthermore, the protective mesh ear plate includes a rectangular bracket and several support bars connected within the rectangular bracket, the support bars dividing the interior of the rectangular bracket into several installation areas.

[0011] Furthermore, the ventilation component is installed in a one-to-one configuration with the installation area.

[0012] Furthermore, the ventilation component is a perforated plate hinged to the protective mesh ear plate or a windmill structure.

[0013] Furthermore, there are at least two ventilation components, and both of the ventilation components are perforated plates, or both of the ventilation components are windmill structures, or at least two of the ventilation components are partially perforated plates and partially windmill structures.

[0014] Furthermore, the support bars are connected by connecting rods, and the perforated plate is connected to the connecting rods by a rotating buckle and can rotate relative to the connecting rods under the action of wind.

[0015] Furthermore, a reset structure is formed between the rotating buckle and the connecting rod, and the mesh plate is reset and closes the pressure relief port under the action of the reset structure.

[0016] Furthermore, a limiting structure is provided between the rotating buckle and the connecting rod to limit the rotation angle of the perforated plate, wherein the rotation angle ranges from 0° to 90°.

[0017] Furthermore, the limiting structure includes a locking block and a sliding groove, one of which is disposed on the rotating buckle, and the other is disposed on the connecting rod.

[0018] Furthermore, the windmill structure includes a rotating shaft, several blades connected to the rotating shaft, and sleeves connected to both ends of the rotating shaft. The rotating shaft can rotate within the sleeves, and two sleeves are respectively connected to the protective net ear plates.

[0019] The beneficial effects of this invention are as follows: By setting a windproof net on the frame of the windproof climbing scaffold, and providing at least one ventilation component that can rotate under the action of wind on the protective net ear plate, when a strong wind blows, the ventilation component rotates to form a pressure relief port with the protective net ear plate, guiding part of the wind force through the pressure relief port to release it, thereby reducing the pressure of the wind on the windproof climbing scaffold, reducing the pressure exerted on the building by the windproof climbing scaffold due to strong wind, and at the same time reducing the wind resistance through the pressure relief port, reducing the generation of wind vibration effect, and improving the stability and safety of the building or equipment.

In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on this invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figure 1 A preferred embodiment of this application shows a wind-resistant climbing scaffold protective net device, which is installed on the periphery of a building wall. The device is characterized in that it includes a frame (not shown), two sets of connecting structures (not shown), a drive system (not shown), and several protective nets.

[0027] The scaffolding consists of scaffold boards, uprights set on the scaffold boards, and triangular supports connecting the uprights. Multiple layers of scaffold boards are spaced apart and fixedly connected to the triangular supports. The working area is formed between adjacent scaffold boards to provide a construction platform for construction workers.

[0028] Two sets of connection structures are installed on both sides of the frame and connected to the wall. Each set of connection structures includes at least two guide components spaced apart on the wall along the height direction, a guide rail installed on the frame, and a fall arrestor formed on the guide rail and guide components. The guide components are slidably connected to the guide rail, allowing the frame to move along the height direction. The guide components and fall arrestor components are set separately, or a wall-mounted guide seat with guiding, fall arrest, anti-tilting, and load-bearing functions can be used. The wall-mounted guide seat slides with the guide rail and has a fall arrestor function; this is existing technology and will not be described in detail here.

[0029] The drive system is used to move the frame along the length of the guide rail. The drive system includes an inverted hoist assembly and a drive control box electrically connected to the inverted hoist assembly. The inverted hoist assembly includes an upper hanging member mounted on the wall, upper and lower lifting point trusses mounted on the uprights of the frame, a lower hanging member mounted on the lower lifting point truss, and an inverted hoist. Hooks on the lifting chain of the inverted hoist are connected to the upper and lower hanging members respectively. The drive control box controls the inverted hoist to drive the lifting chain to move, thereby moving the frame upwards or downwards. This is existing technology and will not be described in detail here.

[0030] Several protective nets are installed on the outside of the frame, which is rectangular in shape. The protective nets are connected and fixed to the uprights by T-bolts. The protective nets are laid on the outside of the frame, mainly the three sides excluding the side close to the wall. The protective nets are mainly used to resist wind force, reduce the direct pressure of wind on the building, and facilitate ventilation and heat dissipation. In addition, they can prevent construction materials from falling and also protect the safety of construction workers.

[0031] The protective netting includes protective netting ear plates 10 and at least one ventilation component installed within the protective netting ear plates 10. The ventilation component rotates under wind force to form a pressure relief port between itself and the protective netting ear plates 10. The protective netting ear plates 10 are fixedly connected to the uprights. When the wind is light, the ventilation component ventilates itself to relieve pressure. When strong winds blow, the ventilation component rotates, creating a pressure relief port between its periphery and the protective netting ear plates 10. This prevents the ventilation component from bearing excessive pressure from strong winds, which could lead to excessive wind load on the windproof climbing frame structure and the wall. To prevent the rotation of the ventilation component from hindering the work of construction personnel and to ensure their safety, a sufficient gap is provided between the windproof netting and the construction platform to allow the ventilation component to rotate. This gap is separated from the construction platform by railings.

[0032] The protective netting ear plate 10 includes a rectangular bracket and several support strips connected within the rectangular bracket. These support strips divide the interior of the rectangular bracket into several installation areas. In this embodiment, the protective netting ear plate 10 is rectangular, with two support strips connected along its inner diagonal. These two support strips divide the interior of the rectangular bracket into four triangular installation areas. In other embodiments, the dividing strips 11 can be of other numbers and connected in other ways. For example, two mutually perpendicular dividing strips 11 can divide the interior of the rectangular bracket into four rectangular areas. Specific limitations are placed on the shape of the installation areas, the number of dividing strips 11, and the connection method, as long as the aforementioned effect is achieved.

[0033] The ventilation components are installed in a one-to-one configuration with each installation area. This ensures that all installation areas can form pressure relief vents when encountering strong winds, thereby maximizing the pressure relief effect.

[0034] In one embodiment, the ventilation component is a perforated plate 20 hinged to the protective mesh ear plate 10. The shape of the perforated plate 20 is adapted to the installation area. The perforated plate 20, when installed within the installation area, can seal off the installation area and can also rotate under wind force. The perforated plate 20 is hinged to the protective mesh ear plate 10. When the wind force is small, the wind cannot move the perforated plate 20, and the perforated plate 20 hangs down naturally to roughly seal off the installation area, allowing ventilation through the perforations in the perforated plate 20. When strong winds occur, the wind blows the perforated plate 20 to rotate along the hinge point, so that the edge of the perforated plate 20 is offset from the inner wall of the installation area to form a pressure relief port. The stronger the wind, the larger the pressure relief port, and the better the pressure relief effect.

[0035] In one embodiment, the ventilation component can also be a windmill structure, which includes a rotating shaft 30, several blades 31 connected to the rotating shaft 30, and sleeves 32 connected to both ends of the rotating shaft 30. The rotating shaft 30 can rotate within the sleeves 32, and the two sleeves 32 are respectively connected to the protective mesh ear plates 10. In this embodiment, the rotating shaft 30 and the sleeves 32 can be connected by a ball joint connection structure or by a bearing. Four blades 31 are arranged along the axis of the rotating shaft 30, and the four blades 31 form a 90° angle with each other. The two sleeves 32 are respectively connected to two support bars. When the wind force is small, the wind force blows the windmill structure to rotate slowly, and the blades 31 rotate to form a pressure relief port that opens and closes continuously with the inner wall of the installation area for ventilation and pressure relief. When there is a strong wind, the wind force blows the windmill structure to rotate rapidly, so that the pressure relief port opens and closes faster, providing a faster pressure relief speed and improving the pressure relief effect.

[0036] There are at least two ventilation components, both of which are perforated plates 20, or both are windmill structures, or at least two ventilation components are partially perforated plates 20 and partially windmill structures. Whether the installation area uses perforated plates 20 or windmill structures is not specifically limited here and can be set as needed.

[0037] In this embodiment, there are four triangular installation areas. Two installation areas symmetrical along the height direction are equipped with triangular mesh plates, and two installation areas symmetrical along the horizontal direction are equipped with windmill structures. The projection of the windmill structure is roughly rectangular, and there are gaps when it fits with the triangular installation areas. To prevent building materials from falling through the gaps, steel plates with mesh holes of the corresponding shape can be welded at the gaps. The windmill structure can be directly welded to the steel plate, or a reinforcing strip can be set on the fixed steel plate. The reinforcing strip is welded to the steel plate, the partition strip 11, the sleeve 32, and the protective net ear plate 10, respectively.

[0038] Specifically, the support bars are connected by a connecting rod 2121. The perforated plate 20 is connected to the connecting rod 2121 by a rotating buckle 22 and can rotate relative to the connecting rod 2121 under the action of wind. There are two rotating buckles 22, which are sleeved on the connecting rod 2121 at intervals and fixedly connected to the perforated plate 20, so that the perforated plate 20 is more stable when it rotates. At the same time, the fixed position of the rotating buckle 22 and the perforated plate 20 should ensure that the center of gravity of the perforated plate 20 is located below the connecting rod 2121. That is, when the wind is not strong enough to blow the perforated plate 20, the perforated plate 20 will naturally droop down under the action of gravity to achieve reset.

[0039] A reset structure (not shown) is formed between the rotating buckle 22 and the connecting rod 2121. The perforated plate 20 is reset and the pressure relief port is closed under the action of the reset structure. The reset structure is a coil spring, which is sleeved on the connecting rod 2121. The two ends of the coil spring are respectively connected to the rotating buckle 22. The coil spring is in a pre-compression state to prevent the perforated plate 20 from being reset when the gravity is insufficient. The coil spring provides a force to reset the perforated plate 20. At the same time, the coil spring can also increase the lower limit of the wind load that drives the perforated plate 20 to rotate, preventing the perforated plate 20 from rotating when the wind will not affect the windproof climbing frame.

[0040] A limiting structure (not shown) is provided between the rotating buckle 22 and the connecting rod 2121 to limit the rotation angle of the perforated plate 20, with the rotation angle ranging from 0° to 90°. Specifically, the 0° position of the perforated plate 20 is the position where the mesh naturally hangs down, and the 90° position is the position where the perforated plate 20 is perpendicular to the protective mesh ear plate 10. Under wind force, the perforated plate 20 rotates between 0° and 90° to form pressure relief vents of different sizes depending on the wind force. Simultaneously, it also prevents the perforated plate 20 from rotating 360°, which would affect the pressure relief effect. By setting up two ventilation components, the perforated plate 20 and the windmill structure, and in conjunction with the reset structure, the pressure relief effect of the windproof climbing frame can increase according to the wind force. When the wind force is insufficient to move the windmill structure, pressure relief is mainly achieved through the perforations. When the wind force moves the windmill structure but is insufficient to move the perforated plate 20, pressure relief is mainly achieved through the pressure relief port formed by the perforations and the windmill structure. When the wind force is sufficient to move the perforated plate 20, pressure relief is mainly achieved through the pressure relief port formed by the perforated plate 20 and the pressure relief port formed by the windmill structure.

[0041] The limiting structure (not shown) includes a locking block and a sliding groove. One of the locking block and the sliding groove is disposed on the rotating buckle 22, and the other is disposed on the connecting rod 2121. In this embodiment, two 90° arc-shaped sliding grooves are symmetrically formed on the connecting rod 2121, and correspondingly, two locking blocks that cooperate with the arc-shaped sliding grooves are disposed on the rotating buckle 22. When the rotating buckle 22 rotates, the locking blocks slide within the arc-shaped sliding grooves. Of course, in other embodiments, the arc-shaped sliding grooves can also be disposed on the rotating buckle 22, and the locking blocks can be disposed on the connecting rod 2121. This is a specific limitation, as long as the above-mentioned effect can be achieved.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
