Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a new type of protective shed for building engineering. Background Technology

[0002] In today's construction engineering field, safety remains paramount. With the continuous advancement of urban construction, various construction projects are springing up like mushrooms after rain. Construction site environments are complex, posing numerous potential safety risks, such as falling objects from heights and accidental falls, constantly threatening the lives of construction workers. Protective sheds, as an important safety protection facility, have emerged to address this need. They are mainly erected in specific areas of the construction site, such as above building entrances and material storage areas. Their role is crucial; they effectively block falling objects from heights, preventing injury to personnel and materials below. Simultaneously, protective sheds provide construction workers with a relatively safe temporary working space, offering shelter from wind and rain, sun protection, and cooling during inclement weather conditions such as heavy rain and intense sunlight, ensuring workers can continue to operate normally. Past construction accidents have frequently resulted in tragedies caused by the inadequate installation of protective sheds. This has led the construction industry to increasingly emphasize the importance of protective sheds, continuously researching and improving their design and materials to ensure they better meet the safety protection needs of construction projects.

[0003] For example, patent CN218990993U discloses a protective canopy for construction projects, relating to the field of engineering protection technology. It includes a support column, a canopy fixedly connected to the top of the support column, a buffer protection component at the top of the canopy, and a fixed base fixedly connected to the bottom of the support column. A portable moving component is located at the bottom of the fixed base. The disclosed buffer protection component, specifically, uses a rubber-made buffer air cushion that deforms upon contact with a falling object to initially buffer the impact force. Furthermore, a buffer block slides down a buffer rod under pressure, compressing a spring. The spring's reaction force provides secondary buffer protection against the impact force, thereby effectively improving the buffer protection performance against falling objects. This prevents the impact force from being too great due to the simple structure, which could cause the falling object to penetrate the canopy and injure equipment and workers below, thus improving safety.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing protective shed for construction projects cannot be folded and stored, making it inconvenient to transport. When it needs to be moved after the construction period is over, it becomes quite troublesome. In addition, the existing protective shed for construction projects cannot be height-adjusted, and cannot be adjusted to a suitable height as needed. Therefore, there is room for improvement. To address these issues, we designed a new type of protective shed for construction projects to provide another technical solution. Utility Model Content

[0005] Therefore, it is necessary to provide a new type of protective shed for construction projects to address the aforementioned technical problems, and to solve the technical issues of folding and storage, height adjustment, and falling object cushioning.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A novel protective canopy for construction projects includes a base, supporting columns, and a roof. The bottom of the base is equipped with multiple supporting columns, the top of the base is equipped with a roof, a folding and storage mechanism is installed between the base and the supporting columns, a height adjustment mechanism is installed inside the supporting columns, and a falling object buffer mechanism is installed between the base and the roof.

The first rotating shaft is rotatably connected to the support column. The second rotating shaft is rotatably connected inside one side of the support column. The second rotating shaft is fixed outside the second rotating shaft. One end of the reinforcing strip is threaded with a screw. One end of each of the screws is threaded to the base.

[0009] Preferably, the height adjustment mechanism includes a transmission rod, a rotating disk, a driving bevel gear, a driven bevel gear, a threaded screw, a bearing, and a telescopic bar. The transmission rod is rotatably connected to one end of the support column, a rotating disk is fixed to one end of the transmission rod, and a driving bevel gear is fixed to the other end of the transmission rod. The driven bevel gear is externally meshed with the driving bevel gear, a threaded screw is internally fixed to the driven bevel gear, a bearing is fixed to the top of the threaded screw, the bearing is fixed to the support column, and a telescopic bar is threadedly connected to the external end of the threaded screw. The telescopic bar is slidably connected to the support column.

[0010] Preferably, the falling object buffer mechanism includes a sliding platform, guide columns, a limiting plate, and a spring. The bottom of the canopy is fixed with a sliding platform, which is slidably connected to the base. Multiple guide columns are evenly distributed and fixed at the bottom of the sliding platform. The bottom of each guide column is fixed with a limiting plate. A spring is sleeved on the outside of the guide column and between the sliding platform and the base.

[0011] Preferably, a light is fixed to the bottom of the base, and a switch is fixed inside one of the support columns.

[0012] Preferably, a stabilizing plate is fixed to the bottom of the telescopic strip, and multiple mounting holes are evenly distributed inside the stabilizing plate.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Example 1

[0035] Reference Figure 1 - Figure 8 A new type of protective shed for construction engineering includes a base 1, support columns 2 and a roof 3. The bottom of the base 1 is equipped with multiple support columns 2, the top of the base 1 is equipped with a roof 3, a folding and storage mechanism is installed between the base 1 and the support columns 2, a height adjustment mechanism is installed inside the support columns 2, and a falling object buffer mechanism is installed between the base 1 and the roof 3.

[0036] The folding and storage mechanism includes a U-shaped base 4, a first rotating shaft 5, a second rotating shaft 6, reinforcing strips 7, and screws 8. The four inner corners of the bottom of the base 1 are fixed with U-shaped bases 4. The first rotating shaft 5 is fixed inside the U-shaped base 4 and is rotatably connected to the support column 2. The second rotating shaft 6 is rotatably connected to one side of the support column 2. Reinforcing strips 7 are fixed to the outside of the second rotating shaft 6. Screws 8 are threaded into one end of the reinforcing strip 7, and one end of each screw 8 is threaded into the base 1. When the protective shed for construction projects needs to be folded... When folding and storing for convenient and flexible transportation, multiple screws 8 are rotated counterclockwise so that one end of the screw 8 is removed from the internal thread of the base 1. This causes the screws 8 and the reinforcing strip 7 to rotate around the second pivot 6 at a certain angle, allowing the reinforcing strip 7 to enter the groove opened inside the support column 2 for storage. Then, the support column 2 is rotated 90 degrees around the first pivot 5 so that the support column 2 and the base 1 are parallel. This allows multiple support columns 2 to be stored inside the base 1, thus enabling folding and storage for convenient transportation of protective sheds used in construction projects.

[0037] The falling object buffer mechanism includes a sliding platform 16, guide posts 17, a limiting plate 18, and a spring 19. The sliding platform 16 is fixed to the bottom of the canopy 3, and the sliding platform 16 is slidably connected to the base 1. Multiple guide posts 17 are evenly distributed and fixed to the bottom of the sliding platform 16, and a limiting plate 18 is fixed to the bottom of each guide post 17. A spring 19 is sleeved on the outside of the guide posts 17, located between the sliding platform 16 and the base 1. When a falling object occurs, the canopy 3 buffers the falling object, causing it to land on the top of the canopy 3. The canopy 3 then causes the sliding platform 16 to slide downwards inside the base 1. As the sliding platform 16 slides downward, the bottom of the sliding platform 16 compresses multiple springs 19, causing the springs 19 to contract under force. The contraction of the springs 19 provides a buffering effect. When the sliding platform 16 slides inside the base 1, the outside of the sliding platform 16 and the inside of the base 1 act as guides. At the same time, to ensure that the sliding platform 16 slides smoothly inside the base 1, multiple guide posts 17 are also used for guidance. The limiting plate 18 at the bottom of the guide post 17 limits the relative position between the sliding platform 16 and the base 1, achieving stable and reliable buffering during sliding.

[0038] A light 20 is fixed to the bottom of the base 1, and a switch 21 is fixed inside one of the support columns 2. The light 20 fixed to the bottom of the base 1 can provide illumination for use when the light is insufficient. The switch 21 can effectively control the light 20. The switch 21 is set in a groove opened inside one of the support columns 2 to avoid accidental contact and damage during folding and storage, which would affect normal use.

[0039] A stabilizing plate 22 is fixed to the bottom of the telescopic strip 15. Multiple mounting holes 23 are evenly distributed inside the stabilizing plate 22. The stabilizing plate 22 increases the contact area when the protective shed for construction projects comes into contact with the ground, thus providing good stability. The multiple mounting holes 23 evenly distributed inside the stabilizing plate 22 can be used to fix it with screws, ensuring that the protective shed for construction projects is stable and secure during use, and avoiding unnecessary accidental injuries caused by instability in severe weather.

[0040] The base 1 is fixed with casters 24 at all four corners at the bottom; the base 1 is fixed with handles 25 at both ends; the casters 24 and handles 25 make it easy for the protective shed for construction projects to be folded and stored, and to turn and move flexibly. The handles 25 provide convenient operation, making it easy for users to push, pull and control the direction of movement.

[0041] Example 2

[0042] Reference Figure 4 A novel protective canopy for construction projects includes a height adjustment mechanism comprising a transmission rod 9, a rotating disk 10, a driving bevel gear 11, a driven bevel gear 12, a threaded screw 13, a bearing 14, and a telescopic bar 15. The transmission rod 9 is rotatably connected to one end of the support column 2. The rotating disk 10 is fixed to one end of the transmission rod 9, and the driving bevel gear 11 is fixed to the other end of the transmission rod 9. The driven bevel gear 12 is externally meshed with the driving bevel gear 11. The threaded screw 13 is fixed internally to the driven bevel gear 12, and a bearing 14 is fixed to the top of the threaded screw 13. The bearing 14 is fixed to the support column 2. The telescopic bar 15 is threadedly connected to the external end of the threaded screw 13, and the telescopic bar 15 slides against the support column 2. The structure is dynamically connected; when the height of the protective shed for construction projects is adjusted according to actual needs, the rotating disk 10 is rotated, which drives the transmission rod 9 to rotate. The transmission rod 9 drives the driving bevel gear 11 to rotate, which in turn drives the driven bevel gear 12 to rotate. The driven bevel gear 12 drives the threaded screw 13 to rotate, and the threaded screw 13 drives the telescopic strip 15 to slide inside the support column 2. By rotating multiple rotating disks 10, the height of the protective shed for construction projects can be adjusted according to actual needs. It should be noted that when folding and storing, the telescopic strip 15 must be fully retracted into the support column 2 to achieve folding and storage.

[0043] The usage process of the novel protective shed for construction projects provided by this utility model is as follows:

[0044] When the protective shed for construction projects needs to be folded and stored for convenient and flexible transportation, U-shaped seats 4 are fixed to the four inner corners of the bottom of the base 1. A first rotating shaft 5 is fixed inside the U-shaped seat 4. The first rotating shaft 5 is rotatably connected to the support column 2. A second rotating shaft 6 is rotatably connected to one side of the support column 2. A reinforcing strip 7 is fixed to the outside of the second rotating shaft 6. A screw 8 is threadedly connected to one end of the reinforcing strip 7. One end of each screw 8 is threadedly connected to the base 1. By rotating the screws 8 counterclockwise, one end of the screw 8 is removed from the internal threads of the base 1. This causes the screws 8 and the reinforcing strip 7 to rotate around the second rotating shaft 6 at a certain angle, allowing the reinforcing strip 7 to enter the groove opened inside the support column 2 for storage. Then, by rotating the support column 2 around the first rotating shaft 5 by ninety degrees, the support column 2 and the base 1 become parallel, allowing the multiple support columns 2 to be stored inside the base 1. This allows for folding and storage, making the protective shed for construction projects convenient for transportation.

[0045] When the height of the protective canopy for construction projects is adjusted according to actual needs, a transmission rod 9 is rotatably connected to one end of the support column 2. A rotating disk 10 is fixed to one end of the transmission rod 9, and a driving bevel gear 11 is fixed to the other end of the transmission rod 9. A driven bevel gear 12 is externally meshed with the driving bevel gear 11. A threaded screw 13 is fixed inside the driven bevel gear 12, and a bearing 14 is fixed to the top of the threaded screw 13. The bearing 14 is fixed to the support column 2, and a telescopic strip 15 is externally threaded to the threaded screw 13. The telescopic strip 15 is slidably connected to the support column 2. Furthermore, the rotation... Rotating the rotating disk 10 drives the transmission rod 9 to rotate, which in turn drives the driving bevel gear 11 to rotate. The driving bevel gear 11 then drives the driven bevel gear 12 to rotate, which in turn drives the threaded screw 13 to rotate. The threaded screw 13 then drives the telescopic strip 15 to slide inside the support column 2. By rotating multiple rotating disks 10, the height of the protective canopy for construction projects can be adjusted according to actual needs. It should be noted that when folding and storing, the telescopic strip 15 must be fully retracted into the support column 2 to achieve folding and storage.

[0046] When an object falls from a height, the canopy 3 cushions the impact. A sliding platform 16 is fixed to the bottom of the canopy 3, slidably connected to the base 1. Multiple guide posts 17 are evenly distributed and fixed to the bottom of the sliding platform 16, with a limit plate 18 fixed to the bottom of each guide post 17. A spring 19 is sleeved on the outside of the guide posts 17, located between the sliding platform 16 and the base 1. As the falling object lands on top of the canopy 3, the canopy 3 causes the sliding platform 16 to slide downwards within the base 1. Simultaneously, as the sliding platform 16 slides downwards... The bottom of the sliding platform 16 compresses multiple springs 19, causing the springs 19 to contract under force. The contraction of the springs 19 provides a buffering effect. When the sliding platform 16 slides inside the base 1, the outside of the sliding platform 16 and the inside of the base 1 act as guides. At the same time, to ensure that the sliding platform 16 slides smoothly inside the base 1, multiple guide posts 17 are also used for guidance. The limiting plate 18 at the bottom of the guide post 17 limits the relative position between the sliding platform 16 and the base 1, achieving stable and reliable buffering during sliding.
