Description

Technical Field

[0001] This invention relates to the field of structural construction technology for protection, and in particular to a roller shutter-type edge protection structure and its construction method. Background Technology

[0002] With the rapid development of my country's economy, buildings are becoming increasingly diverse. In the construction process of high-rise and super high-rise buildings, attached lifting scaffolding is widely used for edge protection. After the scaffolding rises with the main structure, other work continues at the edge, posing significant safety hazards to construction workers and increasing the risk of falling objects, making it difficult to guarantee construction safety. For example, patent CN219281220U discloses an attached lifting scaffolding that includes a frame and guide rails. The rear end of the frame is mounted on a wall, and the guide rails are mounted on the front side wall of the frame. It also includes a traction device, a self-locking device, a worktable, a liner, and positioning teeth. The worktable is slidably mounted on the guide rails. A traction device is located at the top of the frame to move the worktable up and down. The liner is mounted on the front side wall of the frame, and multiple sets of positioning teeth are located on the front side wall of the liner. A self-locking device is located at the bottom of the worktable, which locks the worktable when it moves downwards by cooperating with the multiple sets of positioning teeth. This protective structure is an open worktable, which cannot meet safety requirements and cannot move flexibly left and right. Therefore, there is an urgent need for a protective structure that is effective and flexible in movement. Summary of the Invention

[0003] The purpose of this invention is to provide a roller shutter-type edge protection structure and its construction method to ensure the safety of edge construction in high-rise and super high-rise buildings, reduce accidents caused by falls, and form effective local protection. After the local edge work is completed, it can move with the construction work surface to achieve free movement and provide real-time and effective protection for workers, thereby reducing the safety risks of local edge work.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A roller shutter-type edge protection structure includes the following components: The hollowed-out roller shutter structure consists of lightweight steel pipes with connecting pieces arranged alternately on the top and bottom, and is connected to the winch. The slide rails are respectively installed on the upper and lower surfaces of the winch housing, including the upper slide rail and the lower slide rail; The slide rail is equipped with pre-reserved bolt holes and is fixed to the plate or beam by pre-embedded bolts. It has an upper slide rail and a lower slide rail. The slide rail is equipped with ball bearings, and the slide rail and the slide track cooperate with each other. The safety screw controls the lateral sliding of the winch on the slide rail. When the winch slides to the desired position in the slide rail, the safety screw is tightened to fix the winch and prevent it from derailing, thereby ensuring the stability of the winch unit. The fastener is used to fix the bottom steel pipe of the roller shutter structure to the lower plate or beam.

[0005] The roller shutter structure is a flexible, retractable steel curtain, and its height is adjusted by a winch.

[0006] The slide rail is integrated with the winch housing.

[0007] A toe plate is installed under the bottom steel pipe of the roller shutter structure.

[0008] The locking mechanism includes an upper section, a lower section, a locking bolt, and a connecting bolt between the upper and lower sections. The locking bolt is located between the upper sections of the locking mechanism, and the lower section is inverted T-shaped and is fixed to the upper section by the connecting bolt.

[0009] The upper section of the fastener has a U-shaped structure, and the upper part of the lower section of the fastener has a U-shaped receiving groove. The U-shaped receiving groove is used to accommodate the connecting plate of the upper section of the fastener, which is located at the lower part of the upper section of the fastener.

[0010] The fastening bolts pass through the top and bottom surfaces of the upper U-shaped structure of the fastening, and the connecting bolts between the upper and lower sections pass through the U-shaped receiving groove and the connecting plate of the upper section of the fastening.

[0011] The bottom steel pipe is placed inside the fixed buckle lock.

[0012] A construction method for a roller shutter-type edge protection structure includes the following steps: Step 1: Install the pre-embedded bolts for fixing the slide rail on the slab or beam, and install three fasteners at the corresponding positions on the lower slab or beam. Step 2: Install the slide rail onto the panel or beam and secure it with pre-embedded bolts; Step 3: Install the power distribution device of the winch unit, lift the unit to the slide rail, assemble the slide rail and slide track, and assemble the hollow roller shutter structure. Step 4: Slide the openwork roller blind structure to the desired position, tighten the safety screws to fix the roller blind structure, and then unfold the roller blind structure; Step 5: Place the bottommost lightweight steel pipe of the roller shutter structure into the fastener and tighten the fastener bolts; Step 6: Place the toe guard at the bottom, align it with the screw holes, and fix it to the roller shutter structure; Step 7: After completing the local edge work, continue to install the slide rail on the plate or beam, loosen the safety screws, unlock the bottom fastener, slide the unit to the work surface, and operate according to the above steps.

[0013] The spacing between the lightweight steel pipes is 100mm, the spacing between the connecting plates is 80mm, and the spacing between the toe plates is 200mm.

[0014] The beneficial effects of this invention are as follows: (1) The roller shutter type edge protection structure uses connecting plates to fix lightweight steel pipes, reducing the swing amplitude, and adopts a hollow structure to reduce the wind resistance coefficient, so as to ensure its firmness and reliability.

[0015] (2) The roller shutter type edge protection structure uses lightweight steel pipes of fixed length and connecting plates to form a steel curtain of fixed width; the connecting plates are used to connect the lightweight steel pipes to form a flexible and retractable steel curtain. The height of the steel curtain can be adjusted by the winch to achieve a fixed width and diversified height to meet different protection needs of construction.

[0016] (3) By designing two sliding tracks, the installation needs of the plate or beam can be adapted to meet the different requirements of upper sliding or lower sliding.

[0017] (4) The slide rail is designed with ball bearings to reduce sliding resistance; the safety screws allow the protective structure to be loosened or fixed as needed, which can ensure the stable fixation of the roller shutter structure and also allow for flexible movement of the roller shutter structure.

[0018] (5) The bottom steel pipe of the protective structure is fixed to the slab or beam by a fixing lock, so that it will not flutter like a curtain in the wind, thus ensuring the stability of the protective structure. The fastener is designed in two sections, which can be connected and installed together during the installation of the protective structure. The upper section can be disassembled separately for easy reuse.

[0019] (6) The roller shutter-type edge protection structure is fixed by safety screws. The slide rail and slide track work together, making installation and disassembly convenient and quick, which can greatly improve the construction progress and work efficiency.

[0020] (7) The roller shutter type edge protection facility uses lightweight steel pipes and steel connecting plates to connect with each other, which has good durability, can adapt to long-term working use, and is easy to reuse. Attached Figure Description
