Description

Technical Field

[0001] This utility model relates to the field of building construction, and more specifically, to a protective frame for building construction. Background Technology

[0002] With the continuous acceleration of urbanization in my country, more and more high-rise buildings are appearing before us, and construction workers on the exterior walls will face a more severe working environment at height. The characteristics of building construction are a large workload at height and a complex and changeable working environment, which makes it very easy for accidents of falling from height to occur.

[0003] A search revealed an existing patent (publication number: 202222394343.3) that discloses a construction safety frame, belonging to the field of safety frame technology. It includes a main body of the safety frame and multiple construction positioning rods arranged in a rectangular array to form the main body. The outer walls of the construction positioning rods have multiple T-shaped sliding grooves arranged in a rectangular array. Mounting frames are detachably fixed between the multiple construction positioning rods. Connecting rods are symmetrically fixed between two construction positioning rods on the same side. First sliding parts are symmetrically fixed at both ends of the mounting frames, and second sliding parts are fixed at both ends of the connecting rods. Positioning grooves are formed on the inner walls of the sliding grooves. Positioning blocks that fit and insert into the positioning grooves are elastically installed on the side walls of the first and second sliding parts. This construction safety frame facilitates installation and disassembly, improving the convenience of setting up and retrieving the construction safety frame.

[0004] The patent documents cited above only address the ease of setting up and retrieving protective frames for construction, without providing protection around the construction load-bearing plate or devices to prevent falling objects from heights. This could lead to workers potentially falling from the construction load-bearing plate and getting injured, while falling objects could also injure workers, affecting their personal safety.

[0005] Therefore, a construction safety frame is proposed to address the above problems. Utility Model Content

[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] Example 1

[0026] As attached Figures 1 to 3 The construction safety frame shown includes a platform 1, a guardrail 2 fixedly connected to the top of the platform 1, a buckle 3 fixedly connected to the side wall of the guardrail 2, and a safety mechanism 4 set at the top of the guardrail 2. The safety mechanism 4 includes a support rod 401, a support plate 402, a sliding rod 403, a movable rod 404, a spring damper 405, a limiting rod 406, a connecting rod 407, and a safety plate 408.

[0027] A support rod 401 is fixedly connected to the top of the guardrail 2. A support plate 402 is fixedly connected to the top of the support rod 401. A sliding rod 403 is fixedly connected to the inner wall of the support plate 402. A movable rod 404 is slidably connected to the outer wall of the sliding rod 403. A spring damper 405 is fixedly connected to the inner wall of the support plate 402 on one side of the movable rod 404. A limit rod 406 is fixedly connected to the top of the support plate 402. Connecting rods 407 are screwed to both sides of the movable rod 404. A protective plate 408 that is slidably connected to the limit rod 406 is screwed to one end of the connecting rod 407.

[0028] The system works as follows: Workers stand on platform 1, protected by guardrail 2 to prevent falls. One end of a safety buckle is connected to a buckle 3 for secondary protection, preventing workers from losing their footing in strong winds. In the event of a falling object, the object will land on the protective plate 408, pushing it downwards along the outer wall of the limiting rod 406. This, in turn, causes the connecting rod 407 to swing, pushing the movable rod 404 to press against the spring damper 405 and move along the outer wall of the sliding rod 403. The protective plate 408 blocks falling objects, and the spring damper 405 cushions the impact, extending the lifespan of the protective plate 408. This system effectively protects workers from injury by falling objects and prevents falls from platform 1, thus improving safety.

[0029] Example 2

[0030] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4As shown in the following detailed description: Adjustment mechanisms 5 are provided on both sides of platform 1. Each adjustment mechanism 5 includes a base 501, a bracket 502, a servo motor 503, a worm gear 504, a worm wheel 505, a lead screw 506, a slide groove 507, a movable plate 508, and a limit block 509. The base 501 is located below platform 1. The bracket 502 is fixedly connected to the top of the base 501. The servo motor 503 is installed at the bottom of the base 501. The output end of the servo motor 503 is fixedly connected to the worm gear 504. The worm wheel 505 meshes with the side wall of the worm gear 504. The lead screw 506, which penetrates the interior of the base 501, is fixedly connected to the top of the worm wheel 505. A slide groove 507 is provided on the side wall of the bracket 502. The outer wall of the lead screw 506 is threaded with a movable plate 508 that is fixedly connected to the side wall of the platform 1. Limiting blocks 509 that are slidably connected to the slide groove 507 are fixedly connected to both sides of the movable plate 508. Furthermore, when it is necessary to adjust the height of the platform 1, the servo motor 503 is started to drive the worm gear 504 to rotate, which drives the worm wheel 505 to rotate, thereby driving the lead screw 506 to rotate. When the lead screw 506 rotates, it can push the movable plate 508 and the limiting blocks 509 to move along the track of the slide groove 507, thereby driving the platform 1 to rise and fall, and adjusting the height of the platform 1. Thus, the height of the platform 1 can be adjusted according to the needs of the construction site, expanding the scope of use and improving practicality.

[0031] In a preferred embodiment, an electric push rod 6 is provided at the top of the base 501, and a support block 7 is fixedly connected to the output end of the electric push rod 6. A universal roller 8 is fixedly connected to the bottom end of the base 501. Furthermore, the electric push rod 6 pulls the support block 7 upward, so that the universal roller 8 contacts the ground, moving the device to the desired location. Then, the electric push rod 6 pushes the support block 7 downward, so that the universal roller 8 moves away from the ground, thereby facilitating the movement of the device.

[0032] In a preferred embodiment, the outer wall of the connecting rod 407 is inclined, and the movable rod 404 forms a sliding structure with the slide rod 403 through the connecting rod 407 and the spring damper 405. Furthermore, when an object falls onto the protective plate 408, it pushes the protective plate 408 downward along the outer wall of the limiting rod 406, thereby pushing the connecting rod 407 to swing, causing it to push the movable rod 404 to squeeze the spring damper 405 and move along the outer wall of the slide rod 403. Under the action of the spring damper 405, the impact force generated when the object falls from a height is buffered.

[0033] As a preferred embodiment, the guardrail 2 is provided on four sides around the top of the platform 1, and the outer side of the guardrail 2 is mesh-like; furthermore, the guardrail 2 protects the workers and prevents them from falling.

[0034] In a preferred embodiment, the limiting block 509 and the slide groove 507 are both cross-shaped, and the bracket 502 is n-shaped. Furthermore, when the lead screw 506 rotates, it can push the movable plate 508 and the limiting block 509 to move along the trajectory of the slide groove 507. The limiting block 509 and the slide groove 507 limit the movement of the movable plate 508.

[0035] In a preferred embodiment, two sets of movable plates 508 are provided. The platform 1 forms a lifting structure with the base 501 through the lead screw 506 and the movable plate 508. Furthermore, when the lead screw 506 rotates, it can push the movable plate 508 and the limit block 509 to move along the track of the slide groove 507, thereby driving the platform 1 to rise and fall, and adjusting the height of the platform 1, thus facilitating the control of the platform 1 to rise and fall.

[0036] The working process of this utility model is as follows: When using this type of construction safety frame, firstly, the electric push rod 6 pulls the support block 7 upward, so that the universal roller 8 contacts the ground, moving the device to the required location. Then, the electric push rod 6 pushes the support block 7 downward, so that the universal roller 8 is away from the ground. Subsequently, the worker stands on the platform 1, and the guardrail 2 protects the worker from falling. The worker connects one end of the safety buckle to the buckle 3, which provides secondary protection to prevent the worker from losing stability on the platform 1 in case of strong winds. When there is a falling object from above, the object will fall onto the protective plate 408 and push the protective plate 408 downward along the outer wall of the limiting rod 406, thereby pushing the connecting rod 407 to swing, causing it to move downward. The movable rod 404 presses against the spring damper 405 and moves along the outer wall of the slide rod 403. Under the action of the protective plate 408, it blocks falling objects from a height. Under the action of the spring damper 405, it buffers the impact force generated when objects fall from a height, extending the service life of the protective plate 408. Then, when it is necessary to adjust the height of the platform 1, the servo motor 503 is started to drive the worm gear 504 to rotate, which drives the worm wheel 505 to rotate, and then drives the lead screw 506 to rotate. When the lead screw 506 rotates, it can push the movable plate 508 and the limit block 509 to move along the track of the slide groove 507, thereby driving the platform 1 to rise and fall, and adjusting the height of the platform 1. This is the working principle of this type of construction safety frame.

[0037] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
