Description

Technical Field

[0001] The present invention relates to the technical field of building construction safety, in particular to an external frame hard protection structure and a construction method thereof. Background Art

[0002] During the construction of housing projects, a gap of a certain width exists between the external scaffolding and the main structure. Its main function is to facilitate construction operations and accommodate minor deformations of the main structure. Currently, the industry generally uses flexible safety nets for protection. That is, safety nets made of nylon or polyethylene are fixed to the scaffolding poles and the main structure through steel wire ropes, hooks or lashings. However, this type of protection has the following drawbacks: (1) The protection is not tight, and small objects are easy to fall: The mesh size of commonly used safety nets is generally 20mm×20mm~50mm×50mm. Although it can block larger objects, small tools (such as wrenches, bolts), concrete fragments or scattered building materials may still fall through the mesh holes, posing a risk of falling objects from high altitudes, threatening the safety of people and equipment below; (2) Insufficient material strength and poor impact resistance: The breaking strength of nylon or polyethylene safety nets is usually 1500-3000N. They are easily punctured or torn when subjected to impact from sharp objects (such as falling steel bars). In addition, the fibers become brittle after long-term exposure to ultraviolet rays, further reducing their strength. (3) Poor weather resistance and rapid aging: When the safety net is exposed to the sun, rain and temperature changes for a long time, the polyethylene material will show obvious hardening and fading in about 6-12 months. Although nylon net is slightly better, its tensile strength may drop by more than 30% after 2 years, requiring frequent replacement, which increases maintenance costs; (4) Insufficient stability under wind load: In strong winds, the safety net will swing greatly due to its flexible characteristics, and may even collide and rub against the scaffolding, causing the fixing points to loosen or the safety net to be damaged.

[0003] (5) The installation method has gaps and air leakage: Traditional fixation relies on steel wire ropes, but due to the relative displacement between the scaffolding and the main structure or construction vibration, local loosening or detachment is prone to occur, resulting in irregular gaps between the protective net and the structure, further weakening the protective effect.

[0004] Based on the above problems, a more reliable protective device is urgently needed to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the purpose of the present invention is to provide an external frame hard protective structure and a construction method, which effectively solve the problem of objects falling through the gap between the external scaffolding and the building body.

[0006] The technical solution adopted by the present invention to solve its technical problem is: The utility model discloses an external frame hard protection structure, comprising a foot pedal, which is flat on the crossbar of the scaffolding. A baffle 1 is provided on the side of the foot pedal away from the main structure, and a baffle 2 is movably provided on the side of the foot pedal close to the main structure.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The present invention can achieve quick installation through the assembly of the foot pedal and the baffles on both sides, and improves the impact resistance and wind pressure resistance of the external frame protection structure, and effectively prevents small items from falling, thereby improving construction safety; it can avoid local loosening or separation from the main structure caused by construction vibration.

[0008] Preferably, a further technical solution of the present invention is: Preferably, a hinge 1 is provided at both ends of a side of the baffle 1 connected to the foot pedal, and the baffle 1 is connected to the foot pedal through the hinge 1.

DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with specific embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0015] The invention discloses an external frame hard protection structure, which is composed of a plurality of foot pedals 1. The foot pedals 1 are laid flat on a scaffold, and the bottoms of the foot pedals 1 are connected and fixed to the cross bars 2 of the scaffold. The foot pedals 1 serve as working platforms for construction workers.

[0016] A baffle 3 is provided on one side of each footrest 1 away from the main structure. The two ends of the baffle 3 are connected to the footrest 1 through hinges 4. The baffle 3 can be folded upward through hinges 4 to form a 90° angle with the footrest 1 to form a footrest.

[0017] In order to improve the warning effect of the foot guard, a reflective strip is pasted on the upper edge of the guard 3 (the upper edge here refers to the point where the guard 3 is folded upward and forms a 90° angle with the foot pedal 1).

[0018] A baffle 2 5 is provided on the side of each foot pedal 1 close to the main structure. The two ends of the baffle 2 5 are connected to the foot pedal 1 through hinge 2 6. The baffle 2 5 is unfolded to a horizontal state toward the side of the main structure through hinge 2 6. The baffle 2 5 is used to cover the gap between the foot pedal 1 and the main structure.

[0019] In this embodiment, when installing baffle 1 3 and baffle 2 5, the adjacent baffles 1, 2, and footrests 1 can be connected separately first, and then the three can be assembled. Alternatively, the mounting plate on one side of hinge 1 4 can be used to connect two adjacent footrests 1, and then the mounting plate on the other side of hinge 1 4 can be used to connect two adjacent baffles 1, so that the footrests 1 and baffle 1 3 correspond one to one. This method satisfies both the connection of two adjacent baffles 1 through hinge 1 4 and the connection of two adjacent footrests 1 through hinge 1 4. The installation of baffle 2 5 follows the same principle as that of baffle 1 3, using the mounting plate on one side of hinge 2 6 to connect two adjacent footrests 1, and then using the mounting plate on the other side of hinge 2 6 to connect two adjacent baffles 2 5, so that the footrests 1 and baffle 2 5 correspond one to one. This method satisfies both the connection of two adjacent baffles 2 5 through hinge 2 6 and the connection of two adjacent baffles 2 5 through hinge 2 6.

[0020] Based on the above structure, a construction method of an external frame hard protection structure is carried out according to the following steps: S1. Installation Preparation The number and length of the foot pedals 1 are determined according to the distance between two adjacent vertical poles 8 of the scaffolding. The width of the foot pedals 1 and the baffle 2 5 is determined according to the actual distance between the horizontal poles of the scaffolding and the main building. Then the factory manufactures the foot pedals 1, baffle 1 3 and baffle 2 5.

[0021] S2. Main body installation Assemble the foot pedal 1, baffle 1 3 and baffle 2 5 in advance, and connect the foot pedal 1 to baffle 1 3 and baffle 2 5 through hinge 1 4 and hinge 2 6 respectively. After the installation is completed, baffle 1 3 and baffle 2 5 are folded onto the foot pedal 1 respectively, and then lifted to the installation position by a lifting device; when installing the foot pedal 1, fix the bottom of the foot pedal 1 to the scaffolding crossbar 2 according to the construction method of traditional steel tiles.

[0022] S3, baffle protection After the pedal 1 is installed and fixed, flip the baffle 3 upward 90° counterclockwise so that the baffle 3 and the pedal 1 are perpendicular; unfold the baffle 2 5 to a horizontal state so that its edge contacts the surface of the main structure, and the installation is completed.

[0023] S4. Complete the installation of the protective structures at the remaining locations according to steps S2 and S3.

[0024] The present invention can achieve quick installation through the assembly of the foot pedal and the baffles on both sides, and improves the impact resistance and wind pressure resistance of the external frame protection structure, can protect construction workers, effectively shield the gap between the external frame and the building entity, effectively prevent small items from falling, and improve construction safety; it can avoid local relaxation or separation from the main structure due to construction vibration.
