Description

A protective device for building construction Technical Field

[0001] This utility model relates to the field of building protection devices, and in particular to a building engineering protection device. Background Technology

[0002] Construction safety devices refer to various facilities or equipment installed during construction to ensure personnel safety and prevent accidents. Their main function is to isolate dangerous areas, reduce risks such as falls, collapses, and being struck by objects, and ensure construction safety. When construction is carried out above roads, in order to reduce the impact on road traffic, it is usually necessary to install a protective canopy above the road so that a safe passage for pedestrians can be provided under the protective canopy.

[0003] Currently, a Chinese patent with announcement number CN 119737076 A and announcement date of April 1, 2025, proposes a protective device for building construction, including an installation frame for installing a buffer net. A support frame is fixedly connected to the bottom of the installation frame. An unwinding roller and a winding roller are rotatably installed in the installation frame. The unwinding roller is used to unwind the buffer net, and the winding roller is used to wind the buffer net. A drive mechanism for driving the unwinding roller and the winding roller to rotate synchronously is installed on the installation frame. A support mechanism for supporting the buffer net is installed on the installation frame, and the support mechanism is located at the bottom of the buffer net.

[0004] In use, the motor drives the take-up roller and the unwind roller to rotate synchronously, so that the take-up roller can take up the damaged buffer net and the unwind roller can drive the buffer net to unwind, so that the new buffer net can be laid on the protective shed.

[0005] Regarding the aforementioned technologies, when replacing and installing the buffer net, the buffer net is always fixed in the installation frame. After being subjected to partial impact or stretched for a long time, the buffer net will deform, resulting in a reduction in the buffer net's buffering capacity. This, in turn, increases the probability that falling objects will damage the roof. Summary of the Invention

[0006] In order to improve the buffering performance of the protective net and thus extend the service life of the protective device, this utility model provides a protective device for building engineering.

[0007] This utility model provides a protective device for building engineering, which adopts the following technical solution:

[0008] A protective device for building construction includes: a support component, a protective component, and an adjustment component. The protective component includes a protective top and a protective net. The protective top is fixedly disposed on the top of the support component, the adjustment component is fixedly disposed on the top of the support component, and the adjustment component is disposed at the edge of the protective top. The protective net is installed on the adjustment component and is disposed above the protective top.

[0009] By adopting the above technical solution, during installation, the support components are first installed and fixed, followed by the protective top being installed on top of the support components to form a simple protective device. Next, the position of the adjusting components is moved, and the protective net is installed on the adjusting components. Finally, the adjusting components are moved to fully open the protective net and apply prestress to tighten it. When a falling object lands on top of the protective device, it will first fall onto the protective net, thus providing a certain buffering effect and effectively reducing the impact of the falling object on the protective top. Furthermore, if the buffering capacity decreases due to deformation, the buffer net can be further adjusted using the adjusting components to tighten it again, effectively providing a buffering effect. Therefore, by installing a protective net on top of the protective top and using an adjusting component to tighten it, the service life of the protective device can be extended, while also reducing the safety hazard caused by falling objects penetrating the protective top, further enhancing the safety of the protective device.

[0010] Optionally, the support assembly includes a support frame and support rods, with multiple support rods provided. The support frame is installed above the multiple support rods, and the middle position of the support frame is lower than the edge position. The protective top is installed above the support frame, and the middle position of the protective top is lower than the edge position.

[0011] Existing protective canopies are typically cone-shaped or have a high center. When falling objects land on top of the canopy, they tend to roll towards the edge and fall off, posing a safety risk. By adopting the above-mentioned technical solution, both the support frame and the top of the protective canopy are designed with recessed structures. When falling objects land on top of the canopy, they gradually roll to the recessed area above the canopy for unified handling, effectively reducing the safety risk of objects sliding off the edge of the canopy after landing.

[0012] Optionally, four adjustment components are provided, each located at one of the four corners of the support frame. Each adjustment component includes a slide rail, a slider, and an adjusting nut. The slide rail is fixedly mounted above the support frame, the slider is slidably mounted in the slide rail, and the slider has a threaded hole. The adjusting nut is rotatably mounted on the slide rail and engages with the threaded hole. A hook is provided above the slider for securing the protective net.

[0013] By adopting the above technical solution, the protective netting is adjusted by synchronously controlling the adjustment components at its four corners, ensuring uniform stress distribution. During operation, rotating the adjusting nut moves the slider, and the hooks on the slider pull the edges of the protective netting, adjusting the tension of each anchoring point in real time. This distributed adjustment component not only precisely controls the prestress distribution of the protective netting but also compensates for material deformation through local adjustments, maintaining stable buffering performance.

[0014] Optionally, the support frame includes a first rotating link, a second rotating link, and a locking assembly. The middle portions of the first rotating link and the second rotating link are rotatably connected. One end of the first rotating link and one end of the second rotating link are respectively rotatably disposed on the tops of the two support rods. The locking assembly is fixedly disposed on the support rods and is used to limit the included angle between the first rotating link and the second rotating link.

[0015] By adopting the above technical solution, the first and second rotating links are connected by a central rotatable joint, allowing the support frame to be folded and quickly unfolded. After unfolding, a locking assembly fixes the included angle between the first and second rotating links, ensuring a stable support angle and providing stable support for the protective roof. Thus, designing the support frame as a foldable structure facilitates transportation and storage while enabling rapid unfolding and installation to form a stable triangular support structure, improving on-site installation efficiency.

[0016] Optionally, the locking assembly includes a locking nut and a threaded sleeve. The locking nut is rotatably disposed at the ends of the first rotating link and the second rotating link, and the threaded sleeve is sleeved on the support rod. The locking nut and the threaded sleeve are configured to cooperate with each other.

[0017] By adopting the above technical solution, rotating the threaded sleeve, which engages with the locking nut, allows adjustment of the height of the bottom of the first and second rotating links, thereby adjusting the included angle between them. This adjustment allows for two main adjustments: firstly, it adjusts the width of the support frame, enabling flexible adjustment of the protective device according to road width; secondly, it adjusts the tilt angle of the protective top, thus adjusting the angle at which falling objects land on it. In this way, the self-locking characteristic of the threaded engagement effectively reduces the probability of the included angle between the first and second rotating links changing under external force, improving the stability of the support frame while ensuring adjustment accuracy.

[0018] Optionally, the protective top includes a top plate and a hinge, wherein two top plates are provided, and the two ends of the hinge are respectively fixedly mounted on the two top plates.

[0019] By adopting the above technical solution, the double roof plates form an openable structure through hinges. When the angles of the first and second rotating links are adjusted, the angle between the two roof plates can be adjusted accordingly, allowing the protective roof to be flexibly adjusted according to the road width, thus increasing ease of use.

[0020] Optionally, the top plate is provided with reinforcing links, and multiple reinforcing links are provided along the direction of the top plate.

[0021] By adopting the above technical solution, the reinforcing rod forms reinforcing ribs at the top and bottom, which not only effectively improves the impact resistance of the top plate, but also avoids deformation problems caused by local stress concentration through the reasonable distribution of reinforcing ribs.

[0022] Optionally, the protective roof also includes a water collection trough, which is located below the top plate and at the connection between the two top plates.

[0023] By adopting the above technical solution, a water collection trough is set at the junction of the two roof slabs to form a water guiding channel; during rainfall, the water is concentrated and diverted through the water collection trough, reducing the probability of rainwater leakage on the protective roof. At the same time, directional drainage can also protect the internal components from rainwater corrosion.

[0024] Optionally, a water guide strip is also provided at the edge of the top plate.

[0025] By adopting the above technical solution, inclined water guide strips are set around the perimeter of the roof slab. After rainwater gathers on the roof slab, it will flow in a direction along the water guide strips, which can reduce the probability of rainwater flowing back into the interior along the bottom of the roof slab.

[0026] In summary, this utility model has at least one of the following beneficial technical effects:

[0027] By installing a protective net above the protective top and setting up an adjustment component to keep the net taut, the service life of the protective device can be extended, while also reducing the safety hazard caused by falling objects penetrating the protective top, thus further enhancing the safety of the protective device.

[0028] By designing the tops of both the support frame and the protective roof as recessed structures, when falling objects land on top of the protective roof, they will gradually roll to the recessed area above the protective roof for unified handling. This effectively reduces the safety risk of falling objects sliding off the edge of the protective roof after landing on it.

[0029] A locking assembly is installed on the support rod. By cooperating with the threaded sleeve and the locking nut, the included angle between the first rotating link and the second rotating link can be adjusted, thereby adjusting the width of the support frame and allowing the protective device to be flexibly adjusted according to the road width. At the same time, by utilizing the self-locking characteristic of the threaded engagement, the probability of the included angle between the first rotating link and the second rotating link changing under the action of external force can be effectively reduced, thus improving the stability of the support frame.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to Figures 1 to 4.

[0036] This utility model discloses a protective device for building construction. Referring to Figure 1, a protective device for building construction mainly includes a support component 100, a protective component 200, and an adjustment component 300. The support component 100 uses a foldable support frame 120 and an adjustable support rod 110 to form a stable base. The protective component 200 includes a protective top 210 with a concave center and a protective net 220 covering it. The adjustment component 300 is disposed above the protective top 210 for dynamically adjusting the tension of the protective net 220.

[0037] Referring to Figures 1 to 3, the support assembly 100 includes four vertical support rods 110 and a foldable support frame 120. The four support rods 110 are arranged in a rectangular shape and fixedly installed on the ground. The support frame 120 includes a first rotating link 121, a second rotating link 122, and a locking assembly 400 that are rotatably connected. The middle parts of the first rotating link 121 and the second rotating link 122 form an X-shaped hinge structure through a pivot. The upper ends of the first rotating link 121 and the second rotating link 122 are respectively hinged to the tops of two adjacent support rods 110. The lower ends of the first rotating link 121 and the second rotating link 122 are respectively connected to the two support rods 110 through two locking assemblies 400.

[0038] Referring to Figures 1 to 3, the locking assembly 400 includes a threaded sleeve 420 sleeved on the support rod 110 and a locking nut 410 disposed at the ends of the first rotating connecting rod 121 and the second rotating connecting rod 122. A support platform is provided in the middle of the support rod 110, and the bottom of the threaded sleeve 420 is supported on the support platform and rotatably disposed with the support rod 110. The threaded sleeve 420 has a threaded structure on its exterior. By installing the locking nut 410 on the threaded sleeve 420 and rotating the threaded sleeve 420, the locking nut 410 can be displaced axially along the support rod 110, thereby changing the included angle between the first rotating connecting rod 121 and the second rotating connecting rod 122. When the first rotating connecting rod 121 and the second rotating connecting rod 122 are adjusted to a predetermined unfolding angle, the self-locking characteristic of the threaded engagement can maintain structural stability.

[0039] Referring to Figures 1 to 3, the protective assembly 200 includes a protective top 210 located above the support frame 120 and a protective net 220 covering the protective top 210. The protective top 210 includes two rectangular metal top plates 211 and a hinge 212. The two top plates 211 are rotatably connected in the middle by the hinge 212. A reinforcing connecting rod 213 is welded to the bottom surface of the top plate 211 along the length direction of the top plate 211. The top plate 211 can be installed on the support frame 120 by fixing the reinforcing connecting rod 213 on the first rotating connecting rod 121 and the second rotating connecting rod 122. At the same time, when the first rotating connecting rod 121 and the second rotating connecting rod 122 rotate relative to each other, the two top plates 211 will rotate accordingly.

[0040] To reduce rainwater leakage at the joint of the two roof panels 211, an arc-shaped water collection trough 230 is fixed below the joint of the roof panels 211 with screws. The extension direction of the trough is consistent with the length direction of the roof panels 211.

[0041] In order to reduce the backflow of rainwater from the bottom of the top plate 211 to the center, the edge of the top plate 211 is provided with inclined water guide strips 214, which are formed by bending the edge of the top plate 211 downwards.

[0042] Referring to Figures 3 and 4, the protective net 220 is installed above the protective top 210 via the adjustment assembly 300. The adjustment assembly 300 has four sets, located at the four corners of the top plate 211. Each set of adjustment assembly 300 includes a slide rail 310 welded to the top plate 211, a slider 320 that cooperates with the slide rail 310, and an adjusting nut 330. The middle of the slider 320 is provided with a threaded hole 321 that cooperates with the adjusting nut 330. The adjusting nut 330 is installed at the end of the slide rail 310 through a bearing seat and passes through the threaded hole 321 inside the slider 320, forming a screw drive structure. The top of the slider 320 is provided with an inverted J-shaped hook 322 for hooking the protective net 220.

[0043] The protective net 220 is made of metal mesh. During installation, the protective net 220 is first hung on the hook 322 of the slider 320, and the four sets of adjusting nuts 330 are rotated simultaneously to make the slider 320 slide outward, so that the protective net 220 is in a pre-tensioned state.

[0044] When a falling object lands above the protective net 220, the net absorbs kinetic energy through elastic deformation, thus acting as a buffer. If the net becomes loose after the impact, the adjusting nut 330 can be rotated to re-tighten the protective net 220.

[0045] The implementation principle of a building engineering protection device according to an embodiment of this utility model is as follows:

[0046] During installation, the four support rods 110 are arranged in pairs and connected to each other via a support frame 120. First, the middle parts of the first rotating connecting rod 121 and the second rotating connecting rod 122 are fixed with pins, so that the middle parts of the first rotating connecting rod 121 and the second rotating connecting rod 122 are rotatably connected. Next, the upper ends of the first rotating connecting rod 121 and the second rotating connecting rod 122 are respectively hinged to the tops of two adjacent support rods 110. The lower ends of the first rotating connecting rod 121 and the second rotating connecting rod 122 are respectively installed on the threaded sleeves 420 of the support rods 110 via locking nuts 410. Then, the threaded sleeves 420 are rotated to adjust the included angle between the first rotating connecting rod 121 and the second rotating connecting rod 122, and the spacing between the support rods 110 is adjusted. At this time, the top of the support frame 120 formed by the first rotating connecting rod 121 and the second rotating connecting rod 122 has a V-shaped structure.

[0047] After adjusting the included angle between the first rotating link 121 and the second rotating link 122 to a preset angle, the two top plates 211 are respectively installed above the first rotating link 121 and the second rotating link 122 via reinforcing link 213, and the water collection tank 230 is installed below the position where the two top plates 211 are connected by hinge 212 via screws.

[0048] After the top plate 211 is installed, fix the four corners of the protective net 220 to the adjustment components 300 located at the four corners of the top plate 211, and use the hooks 322 on the slider 320 to fix the protective net 220. Finally, rotate the adjusting nut 330, and pull the corners of the protective net 220 through the hooks 322 on the slider 320 to tighten the protective net 220, thus completing the installation. If the protective net 220 becomes loose during subsequent maintenance, the hooks 322 can be moved by readjusting the adjusting nut 330 to tighten the protective net 220 again.

[0049] In summary, this application improves the service life of the protective device by setting a protective net 220 above the protective top 210 and using an adjustment component 300 to tension the protective net 220, while also reducing the safety hazard caused by falling objects penetrating the protective top 210. By setting the tops of both the support frame 120 and the protective top 210 as recessed structures, when a falling object lands above the protective top 210, it will gradually roll to the recessed position above the protective top 210, effectively reducing the safety risk of the falling object sliding off the edge of the protective top 210 after landing on it. By using a threaded sleeve 420 and a locking nut 410 to adjust the angle between the first rotating link 121 and the second rotating link 122, the self-locking characteristic of the threaded engagement can effectively reduce the probability of the angle between the first rotating link 121 and the second rotating link 122 changing under external force, thus improving the stability of the support frame 120.

[0050] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
