Description

Technical Field

[0001] This utility model relates to the field of building protection technology, specifically a building protection device for building engineering. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, accidents caused by falling bricks and objects from heights are prone to occur at the construction site. Therefore, corresponding protective devices are installed in areas where construction workers frequently stay to prevent falling objects from heights and to protect the construction workers below the protective devices.

[0003] In the prior art, a building protection frame with the publication number "CN218862209U" uses an adjustment device on the entire device. Since the position and size of the movable groove are adapted to the position and size of the four support rods, the support rods move within the movable groove. According to the height requirements, the height of the support rods can be adjusted appropriately to determine the applicable height. Adjusting bolts are then threaded through the insertion holes and installed in the first screw hole. The threaded installation method makes assembly and disassembly simple and easy to operate, achieving appropriate height adjustment.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] While the protective frame can intercept falling objects from heights using a net and rubber sheets, the rubber sheets are relatively weak. This means that if the net is damaged by the impact of falling objects, the objects can easily break through the net and shatter the rubber sheets. A broken rubber sheet then fails to adequately protect construction workers below, resulting in poor protection. Furthermore, adjusting the height of the frame requires multiple workers to disassemble and remove the adjusting bolts before the rubber sheets can be adjusted. Therefore, the adjustment device is inconvenient to use and its practicality needs further improvement. Utility Model Content

[0006] The purpose of this utility model is to provide a building protection device for construction projects, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A building protection device for construction projects includes a protective mesh panel, a protective top panel, and a supporting base plate. The protective top panel is installed above the supporting base plate, and the protective mesh panel is installed above the protective top panel. A protective component is provided between the protective mesh panel and the protective top panel, and the protective component is used to enhance the impact resistance of the protective top panel and the protective mesh panel. A supporting component is provided between the supporting base plate and the protective top panel, and the supporting component is used to support the protective top panel and adjust its height.

[0009] Preferably, the protective component includes a first reinforcing inner strip, a first reinforcing strip, a second reinforcing strip, and a second reinforcing inner strip. Multiple first reinforcing strips are fixedly connected to the upper surface of the protective top plate, and a second reinforcing strip is fixedly connected to each of the multiple first reinforcing strips. A first reinforcing inner strip is fixedly connected inside the first reinforcing strip, and a second reinforcing inner strip is fixedly connected inside the second reinforcing strip.

[0010] Preferably, the upper surface of the protective top plate is symmetrically provided with support screws on the left and right sides, the annular side of the support screw is fitted with a compression spring, the upper side of the annular side of the support screw is fitted with a blocking nut, and the upper side of the annular side of the support screw is fitted with a rubber washer.

[0011] Preferably, the support assembly includes a limiting vertical rod, a water storage shell, a limiting station column, and an electro-hydraulic push rod. The limiting station column is installed on the upper surface of the support base plate, the limiting vertical rod is inserted inside the limiting station column, the water storage shell is fixedly connected to the annular side of the limiting station column, and electro-hydraulic push rods are symmetrically installed on the front and rear sides of the upper surface of the support base plate.

[0012] Preferably, the upper end face of the water storage shell is provided with a water inlet, the lower side of the annular side of the water storage shell is provided with a drain outlet, the limiting post is a hollow structure, and the limiting post is matched with the limiting vertical rod.

[0013] Preferably, both the first reinforcing strip and the second reinforcing strip are arched in shape, the length of the first reinforcing inner strip is the same as the length of the first reinforcing strip, and the length of the second reinforcing inner strip is the same as the length of the second reinforcing strip.

[0014] Preferably, the blocking nut has an internally threaded through hole on its side, and a locking screw is installed inside the internally threaded through hole. The upper surface of the protective mesh plate has symmetrical insertion through holes on the left and right sides, and the insertion through holes match the support screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using multiple arched first and second reinforcing strips that are fixedly connected, the upper surface of the protective top plate can be reinforced laterally and longitudinally. The fixedly connected first and second reinforcing inner strips can further improve the deformation resistance of the first and second reinforcing strips, thereby preventing the protective top plate from easily deforming and breaking when subjected to the impact of falling objects from a height. This ensures the blocking and protective capability of the protective top plate. By installing compression springs, the impact kinetic energy of the protective net plate subjected to falling objects from a height can be converted into elastic potential energy and rebounded through contraction deformation, thereby reducing the impact force of falling objects on the protective net plate and preventing the protective net plate from easily deforming and being damaged.

[0017] 2. By controlling the extension and retraction of the electric hydraulic push rod, the height of the protective top plate can be easily adjusted. By installing limit posts and limit rods, the protective top plate is prevented from swaying or shifting during lifting and lowering, thus ensuring the stability of the protective top plate. By filling the water tank with water through the water inlet, the weight of the limit posts can be further increased, thereby improving the stability of the limit posts. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A building safety device for construction projects includes a protective mesh panel 1, a protective top panel 2, and a supporting base plate 3. The protective top panel 2 is installed on top of the supporting base plate 3. The protective top panel 2 is made of high manganese steel and can provide secondary interception of falling objects from above. The protective mesh panel 1 is installed on top of the protective top panel 2 and can provide primary interception of falling objects from above, thereby preventing construction workers below the protective top panel 2 from being injured by falling objects.

[0028] A protective component is installed between the protective netting 1 and the protective top plate 2. The protective component is used to strengthen the impact resistance of the protective top plate 2 and the protective netting 1, and to prevent the protective top plate 2 and the protective netting 1 from being easily deformed and damaged when subjected to the impact of falling objects from a height. A support component is installed between the support base plate 3 and the protective top plate 2. The support component is used to support the protective top plate 2 and adjust its height, so that construction personnel can adjust the usage height of the protective top plate 2 according to the needs of the construction site.

[0029] The protective assembly includes a first reinforcing inner strip 41, a first reinforcing strip 42, a second reinforcing strip 43, and a second reinforcing inner strip 44. Multiple first reinforcing strips 42 are fixedly connected to the upper surface of the protective top plate 2. The first reinforcing strips 42 are arched in shape, providing lateral reinforcement to the upper surface of the protective top plate 2. Second reinforcing strips 43 are fixedly connected to each of the multiple first reinforcing strips 42. The second reinforcing strips 43 are also arched in shape, providing longitudinal reinforcement to the upper surface of the protective top plate 2. A first reinforcing inner strip 41 is fixedly connected inside each first reinforcing strip 42. The length of the first reinforcing inner strip 41 is the same as that of the first reinforcing strip 42, further improving the deformation resistance of the first reinforcing strip 42. A second reinforcing inner strip 44 is fixedly connected inside each second reinforcing strip 43. The length of the second reinforcing inner strip 44 is the same as that of the second reinforcing strip 43, further improving the deformation resistance of the second reinforcing strip 43.

[0030] The first reinforcing inner liner 41, the first reinforcing inner liner 42, the second reinforcing inner liner 43, and the second reinforcing inner liner 44 are all made of high manganese steel, and the first reinforcing inner liner 41, the first reinforcing inner liner 42, the second reinforcing inner liner 43, and the second reinforcing inner liner 44, all made of high manganese steel, have good impact load resistance.

[0031] Supporting screws 47 are symmetrically arranged on the left and right sides of the upper end face of the protective top plate 2. The supporting screws 47 are made of the same material as the protective top plate 2 and are connected to the protective top plate 2 by welding. A blocking nut 46 is installed on the upper side of the annular side of the supporting screw 47. The supporting screws 47 and the blocking nut 46 can install the protective net plate 1 above the protective top plate 2. A compression spring 45 is fitted on the annular side of the supporting screw 47. The compression spring 45 can store and release energy through contraction and deformation. When the protective net plate 1 is impacted by falling objects from a height, it converts the impact kinetic energy into elastic potential energy, thereby reducing the impact force of falling objects from a height and preventing the protective net plate 1 from being easily deformed and damaged by the impact force of large falling objects from a height.

[0032] A rubber washer 48 is fitted on the upper annular side of the support screw 47. The rubber washer 48 is made of high tear-resistant silicone rubber. The rubber washer 48 allows for flexible contact between the blocking nut 46 and the protective mesh plate 1, thereby buffering part of the upward rebound force of the protective mesh plate 1 and preventing the blocking nut 46 from being easily loosened by the excessive upward rebound force of the protective mesh plate 1. The blocking nut 46 has an internal threaded through hole 461 on its side, and a locking screw 462 is installed inside the internal threaded through hole 461. The internal threaded through hole 461 and the locking screw 462 can position the blocking nut 46 and prevent the blocking nut 46 from easily loosening and slipping during use. The upper end face of the protective mesh plate 1 has symmetrical insertion through holes 49 on the left and right sides, and the insertion through holes 49 match the support screw 47. The insertion through holes 49 facilitate the insertion of the support screw 47 into the protective mesh plate 1.

[0033] Example 2:

[0034] Based on Embodiment 1, in this embodiment, the height of the protective top plate 2 can be conveniently adjusted by controlling the extension and retraction of the electric hydraulic push rod 54. By installing the limiting column 53 and the limiting vertical rod 51, the swaying and displacement of the protective top plate 2 during lifting and lowering are prevented, thereby ensuring the stability of the protective top plate 2. By filling the water storage shell 52 with water through the water inlet 55, the weight of the limiting column 53 can be further increased, thereby improving the stability of the limiting column 53.

[0035] The support components include a limiting vertical rod 51, a water storage shell 52, a limiting column 53, and an electro-hydraulic push rod 54. The limiting column 53 is installed on the upper surface of the support base plate 3. The limiting column 53 has a hollow structure and matches the limiting vertical rod 51. The hollow structure of the limiting column 53 can limit the limiting vertical rod 51 and prevent the limiting vertical rod 51 from deviating or swaying during lifting and lowering. The limiting vertical rod 51 is inserted inside the limiting column 53. The material of the limiting vertical rod 51 is the same as that of the protective top plate 2. The limiting vertical rod 51 and the protective top plate 2 are an integral structure. The limiting vertical rod 51 can support the protective top plate 2.

[0036] A water storage tank 52 is fixedly connected to the annular side of the limiting post 53. The water storage tank 52 and the limiting post 53 are an integral structure. The water storage tank 52 has the capacity to store water, so that construction personnel can increase the self-weight of the limiting post 53 as needed. Two sets of electric hydraulic push rods 54 are symmetrically installed on the front and rear sides of the upper end of the support base plate 3. The two sets of electric hydraulic push rods 54 are of the same specification and are electrically connected to an external synchronous controller through wires. The rod 54 allows construction personnel to control its synchronous extension and retraction, thereby driving the protective top plate 2 to rise and fall. Furthermore, the existing electro-hydraulic push rod 54 has a pressure self-locking mechanism designed in the oil circuit integration block. When the electro-hydraulic push rod 54 stops working, its internal piston rod can self-lock in a certain position and be in a pressure-holding state, preventing the non-working electro-hydraulic push rod 54 from falling back. Since the detailed internal structure and working principle of the electro-hydraulic push rod 54 and the external synchronous controller are relatively mature technologies in the existing technology, they will not be described in detail here.

[0037] A water inlet 55 is provided on the upper surface of the water storage shell 52. The water inlet 55 facilitates the construction personnel to add water to the inside of the water storage shell 52. A drain nozzle 56 is provided on the lower side of the annular side of the water storage shell 52. The drain nozzle 56 can drain and empty the water inside the water storage shell 52. Both the water inlet 55 and the drain nozzle 56 are threaded with sealing caps. The sealing caps can seal the drain nozzle 56 and the water inlet 55.

[0038] Working Principle: During construction projects, accidents involving falling bricks and other objects can easily occur at construction sites. This device is necessary in areas where construction workers frequently stay. During operation, the installed protective netting 1 can initially block falling objects. When an object lands on the netting 1, the compression spring 45 stores energy through deformation, converting the impact kinetic energy into elastic potential energy and causing a rebound. This reduces the impact force on the netting 1, preventing deformation and damage. Furthermore, the rubber washer 48 cushions some of the upward rebound force, preventing the blocking nut 46 from being directly subjected to excessive force from the netting 1. The rebound force causes loosening, and the locking screw 462 can further position the blocking nut 46 to ensure the stability of the blocking nut 46. When the size of the falling object is too large and the protective net plate 1 is damaged, the protective top plate 2 can block the falling object passing through the protective net plate 1 for a second time, so as to prevent the construction workers below the protective net plate 1 from being injured by the falling object. In this process, the fixed connection of multiple arch-shaped first reinforcing strips 42 and second reinforcing strips 43 can reinforce the upper surface of the protective top plate 2 in the horizontal and vertical directions. The first reinforcing inner strip 41 and the second reinforcing inner strip 44 can further improve the deformation resistance of the first reinforcing strip 42 and the second reinforcing strip 43, thereby preventing the protective top plate 2 from easily deforming and breaking when subjected to the impact force of falling objects.

[0039] By installing the electric hydraulic push rod 54, construction personnel can easily adjust the height of the protective top plate 2 according to the needs of the construction site. During this process, the limiting column 53 will limit the limiting vertical rod 51 to prevent the protective top plate 2 from swaying or shifting during lifting and lowering, thus ensuring the stability of the protective top plate 2. When the construction personnel fill the water storage tank 52 with water through the water inlet 55, the water-filled water storage tank 52 can further increase the weight of the limiting column 53, thereby improving the stability of the limiting column 53.
