Description

Technical Field

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

[0002] In construction projects, especially during the construction of basement multi-level buildings, edge protection is a crucial aspect of ensuring construction safety. Traditional protection methods typically involve erecting edge protection railings using a single row of steel pipe poles. This method has the following drawbacks: Poor adaptability to rebar tying conditions: Traditional guardrails are fixed structures. When rebar needs to pass through the protected area during the rebar tying stage, either part of the guardrail needs to be temporarily removed, or the gap between the guardrail and the rebar arrangement do not match, resulting in the rebar not being able to pass through smoothly, which seriously affects the construction efficiency. It is difficult to achieve seamless protection after concrete pouring: After the concrete is poured and the structure is formed, gaps are easily formed between the bottom of the traditional guardrail and the concrete slab, which cannot form a closed protection and poses a safety risk of people or small tools falling. Insufficient structural stability: The spacing between the uprights is set arbitrarily, and they are prone to swaying and displacement when subjected to horizontal forces of 1000N or more, posing significant safety hazards.

[0003] To address the aforementioned issues, there is an urgent need for a staggered protection device that can accurately adapt to rebar tying and concrete pouring, is easy to assemble and disassemble, and is reusable, in order to solve the pain points of adaptability and economy of traditional protection methods. Utility Model Content

[0004] To address the issues of poor protective capacity and safety hazards posed by steel pipes, this utility model provides a staggered construction protection device that can be quickly installed, adapted to different construction conditions, supports flipping and adjustment, and can be reused repeatedly, thus solving many problems of traditional protection methods and existing protection devices.

[0005] The technical solution of this utility model is as follows: A staggered construction protection device, installed on a frame, includes a protective plate, a movable plate, and fasteners. The protective plate is installed above the junction of the blank area of ​​the frame and the ground. The movable plate is rotatably connected to the lower part of the protective plate. The frame and the protective plate are connected by at least one fastener to fix the protective plate to the frame.

[0006] Preferably, the protective plate has a square structure, and a pair of fixing through holes are provided at each of the four opposite corners of the square structure.

[0007] Preferably, the protective plate has a fixing through hole, and the fastener includes a U-shaped clamp. The U-shaped clamp is assembled with the fixing through hole, and a nut is provided to fix the U-shaped clamp and the fixing through hole.

[0008] Preferably, a pad is provided on one side of the fixed through hole, and a U-shaped clamp passes through the fixed through hole and the pad. The U-shaped clamp, the pad and the fixed through hole are fixedly connected by a nut.

[0009] Preferably, the bottom of the protective plate has fixing through holes on both sides, and the top of the movable plate has a clearance position.

[0010] Furthermore, hinges are provided at the bottom of the protective plate and the top of the movable plate, and a rotating shaft is provided in the middle of the hinges on both sides. The hinges on both sides are rotatably connected by the rotating shaft.

[0011] Preferably, the protective plate and the movable plate are each provided with an interwoven grid.

[0012] Preferably, the interwoven mesh is coated with a first paint layer, the first paint layer being yellow in color.

[0013] Preferably, a warning board is provided outside the protective board and the movable board, and the warning board is coated with a second paint layer, which includes red and white stripes.

[0014] Preferably, the warning plate has a connecting through hole corresponding to the fixing through hole, and the warning plate is installed on the outside of the protective plate by a U-shaped clamp.

[0015] According to the above-mentioned solution, the beneficial effects of this utility model are as follows: In this utility model, the protective plate is connected to the blank area of ​​the frame, which increases the connection strength of the frame and avoids the risk of frame deformation under large horizontal forces. The movable plate is rotatably connected to the bottom of the protective plate. The usage state of the movable plate includes 0-180°, which makes the protective plate have a flexible adjustable usage height. In the width direction, multiple protective plates can be arranged side by side to increase the usage width, maximizing the surrounding of the outer open side of the staggered construction space. The above two can realize an enclosed frame protection structure.

[0016] U-shaped clamps, as a quick-fixing component, use steel pipes that surround the frame at both ends and penetrate through fixing holes to selectively enhance the fixing effect with a pad and add an extension connection to the warning plate on the outer side of the protective plate, ultimately fixing the protective plate to the outer open side.

Example 1

[0021] like Figures 1 to 3 As shown, a staggered construction protection device is applicable to scenarios such as staggered basement construction and scaffold-free construction at the junction of high and low buildings. It is installed on the Φ48~50mm steel pipe frame of building construction, such as the basement formwork frame or the outer support frame of the core tube of a super high-rise building. The device is installed above the blank area of ​​the core adapter frame and the ground connection point—that is, the structural gap area where there is a risk of edge movement and protection is required in staggered construction. It achieves rapid docking with the existing construction frame through modular components, while ensuring dynamic adaptation of protection and construction procedures, and meeting the needs of turnover and reuse.

[0022] The protective panel 100 adopts a square modular structure with overall dimensions of 1500mm in length and 1200mm in height. This size precisely matches the conventional spacing of the steel pipe columns in the construction frame, ensuring that a single protective panel 100 can directly cover the blank area between two adjacent steel pipe columns by diagonal fixing, forming a complete protective surface without the need to splice multiple small panels, thus avoiding the cumbersome installation problem of small modular protective panels 100. On the other hand, the height of 1200mm meets the specification requirement that the edge protection height should not be less than 1.2m, and the basic safety protection needs can be met without the need to add extra height to the protective structure before the reinforcement construction.

[0023] The protective plate 100 has a pair of fixing through holes at each of its four opposite corners. The distance between the two fixing through holes is 50mm and the diameter of the fixing through holes is 7mm. The U-shaped clamp 300 is adapted to be installed later. Its inner width is 50mm and its rod diameter matches the 7mm hole diameter. This ensures that the U-shaped clamp 300 can accurately wrap around the frame steel pipe after passing through the fixing through hole, so as to achieve vertical fixation between the protective plate 100 and the frame.

[0024] The pad 310 of the protective plate 100 measures 50mm × 50mm × 3mm, with a 7mm diameter hole in its center corresponding to the fixing through hole. The pad 310 covers the outside of the fixing through hole, increasing the contact area between the U-shaped clamp 300 and the protective plate 100. This prevents the interwoven mesh 500 on the protective plate 100 from being squeezed and deformed when the locking nut 320 is tightened. Simultaneously, the size design of the pad 310 ensures complete coverage of the mesh nodes around the fixing through hole, further enhancing the structural stability of the fixing point and stabilizing the fixing angle between the two protective plates 100. The surface of the interwoven mesh 500 is coated with a yellow first layer of paint, which enhances the visual warning effect and strengthens the corrosion resistance of the galvanized layer, increasing the corrosion resistance life of the protective plate 100 in humid construction environments such as basements.

[0025] To further enhance the visual warning effect of edge protection, the device is additionally equipped with a warning plate made of 2mm thick galvanized iron sheet. The warning plate has the same external dimensions as the protective plate 100. The surface of the plate is coated with a second layer of red and white paint with a red and white diagonal stripe spacing of 200mm, which conforms to the visual warning specifications for edge protection. The warning plate also has a connecting through hole corresponding to the fixing through hole of the protective plate 100. During installation, the warning plate is attached to the outside of the protective plate 100, that is, the side of the protective plate 100 closer to the frame, so that the connecting through hole is aligned with the fixing through hole, and fixed by the same U-shaped clamp 300, so as to achieve synchronous fixing of the warning plate and the protective plate 100.

[0026] The movable plate 200 is designed to be height-matched with the protective plate 100, with overall dimensions of 1500mm in length and 200mm in height. The length is identical to the protective plate 100, ensuring that the movable plate 200 maintains the same width as the protective plate 100 during rotation, preventing gaps due to length discrepancies. The 200mm height addresses two key working conditions: when the movable plate 200 is lowered to a vertical position after concrete pouring, the 200mm height serves as an effective kickboard, preventing workers or small tools from falling from the bottom of the protective structure. Simultaneously, this height compensates for ground height differences within 200mm during staggered construction, ensuring a tight fit between the bottom of the movable plate 200 and uneven ground structures. Before rebar installation, when the movable plate 200 is flipped to a horizontal position, the 200mm height does not occupy excessive space for rebar tying operations, avoiding obstruction of rebar handling and installation procedures.

[0027] A clearance position 210 is provided at the top of the movable plate 200 corresponding to the position of the bottom fixing through hole of the protective plate 100. The clearance position 210 is 50mm long and 20mm wide. Its length is slightly greater than the sum of the rod diameter of the U-shaped clamp 300 and the side length of the pad 310, and its width is adapted to the diameter of the bottom fixing through hole of the protective plate 100. This ensures that when the movable plate 200 rotates within the range of 0° to 180°, the clearance position 210 can completely avoid the U-shaped clamp 300 and the pad 310 at the fixing through hole, without causing jamming or structural interference.

[0028] The rotatable connection between the movable plate 200 and the protective plate 100 is achieved through three sets of 304 stainless steel hinges 400 and a rotating shaft. The dimensions of the hinges 400 are 75mm × 49.5mm × 1.5mm, with the 75mm length arranged along the connection edge between the protective plate 100 and the movable plate 200. The three sets of hinges 400 are respectively installed at the bottom of the protective plate 100 and the top of the movable plate 200 at both ends and the middle position, with a spacing of 730mm to ensure uniform force during rotation. The rotating shaft has a diameter of 10mm and a length of 1500mm. After passing through the shaft holes of the hinges 400 on both sides, the movable plate 200 can rotate freely around the shaft. The diameter design of the rotating shaft ensures sufficient torsional strength to withstand the weight of the movable plate 200 and slight external forces without deformation, and also allows for precise matching with the shaft holes of the hinges 400 to avoid excessive gaps during rotation that could cause the movable plate 200 to wobble.

[0029] Furthermore, the movable panel 200 can be adjusted by rotating its angle to achieve multiple usage modes, precisely matching the different process requirements of staggered-level construction: refer to Figure 4 or Figure 6In the vertical state, corresponding to after concrete pouring: After the concrete pouring is completed and the structure is formed, loosen the temporary fixing parts of the movable plate 200, such as the wrapped thick iron wire, so that the movable plate 200 is naturally lowered to the vertical state around the rotation axis. At this time, the bottom of the movable plate 200 is in contact with the ground or the lower structure surface, forming a continuous vertical protection with the protective plate 100. The total protection height reaches 1400mm, which meets the specification requirement that the edge protection height is not less than 1.2m. Moreover, the interwoven grid 500 of the movable plate 200 is aligned with the interwoven grid 500 of the protective plate 100, with no protective gaps, which can effectively prevent people or objects from falling. refer to Figure 5 In the horizontal / sloping state, corresponding to the pre-reinforcement construction: the movable plate 200 is flipped upward around the rotation axis to a horizontal state, or adjusted to a 30°~60° upward sloping state according to the height of the reinforcement arrangement. The movable plate 200 is tied and fixed to the transverse reinforcing ribs of the protective plate 100 with thick iron wire. At this time, the movable plate 200 is far away from the ground structure, leaving sufficient operating space for the handling and binding of reinforcement, avoiding the problem of the traditional fixed protective plate 100 hindering construction. refer to Figure 1 In the intermediate adjustment state, when a special staggered height is required: for the junction of high and low buildings, such as staggered structures with a height difference of 200mm on both sides of the expansion joint, the movable plate 200 can be adjusted to the corresponding slope angle, such as 0°~90° with the ground on the lower side, so that the bottom of the movable plate 200 is in contact with the ground on the lower side, and the top is in continuous protection with the protective plate 100, compensating for the protection gap caused by the height difference.

[0030] In addition, the interwoven mesh 500 of both the protective plate 100 and the movable plate 200 is set to 50mm×50mm. This aperture can effectively block objects with a diameter greater than 50mm from falling, while not increasing the weight due to excessive mesh density. It is lighter than solid iron plates, making it easier to handle manually and install at heights. The frame of the interwoven mesh 500 is made of the same 40×40×3mm galvanized square tube material as the frame of the protective plate 100, ensuring that the overall structural strength meets the standards after the mesh and frame are welded. When subjected to a horizontal impact force of 1000N, the deformation of both the protective plate 100 and the movable plate 200 is less than 5mm, meeting the structural safety requirements in staggered construction.

[0031] 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.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
