Description

Technical Field

[0001] This utility model relates to the field of construction technology for protection of reserved openings in composite slabs, and in particular to a standardized protection structure for openings in composite slabs constructed with aluminum alloy formwork. Background Technology

[0002] During the construction of aluminum alloy formwork in building engineering, pre-reserved openings are often required for composite slabs, such as pipeline openings and equipment openings. To ensure construction safety, these openings need to be protected to prevent personnel from falling or objects from falling. In current construction processes, the pre-reserved openings at the installation locations of the aluminum alloy formwork and composite slabs are usually protected by binding nets. This protection method has low safety and limited adaptability. Furthermore, because the pre-reserved openings at the installation locations of the aluminum alloy formwork and composite slabs are of different sizes, using only nets requires materials of different widths, which not only wastes materials and has low installation efficiency, but also increases construction costs and time. Moreover, the reuse rate is low, making it difficult to reuse the nets. In addition, it is unsafe, with insufficient protection reliability. The nets are easily damaged and cannot effectively prevent the risk of falling, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a standardized protective structure for the opening of composite slabs in aluminum alloy formwork construction, which can flexibly adapt to different specifications of composite slab openings, improve installation efficiency, and enhance protective safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A standardized protective structure for openings in composite slabs constructed with aluminum alloy formwork includes aluminum alloy formwork at the edge of a pre-reserved opening in the composite slab, adjusting steel plates on opposite sides of the aluminum alloy formwork, a wire mesh between the adjusting steel plates, and a retaining net below the wire mesh. The edges of the wire mesh are wrapped around the adjusting steel plates. Multiple corresponding through holes are evenly spaced between the edges of the adjusting steel plates and the aluminum alloy formwork. Multiple fixing components are provided between the adjusting steel plates and the edges of the aluminum alloy formwork. The retaining net, wire mesh, adjusting steel plates, and aluminum alloy formwork are fixed together by these fixing components. Each fixing component includes a fixing pin and a resetting component located inside one end of the fixing pin. The fixing pin is a hollow rod-shaped structure, and the resetting component includes a fixing plate fixedly disposed inside the fixing pin. The device includes a limiting block installed on the side wall of the fixing pin and connected to the fixing plate, and a control button installed on the side wall of the fixing pin and connected to the limiting block. The limiting block includes a control rod and a protrusion. Multiple compression springs and telescopic guide rods are provided between the protrusion and the fixing plate. The compression springs are sleeved on the telescopic guide rods. A limiting hole is opened on the side wall of the fixing pin. The protrusion extends out of the limiting hole and is slidably connected to the side wall of the fixing pin. The control button is fixed on the control rod. A receiving hole is opened on the side wall of the fixing pin. The control button extends out of the receiving hole and is slidably connected to the side wall of the fixing pin. The fixing component is set through the through holes of the mesh, wire mesh, adjusting steel plate and aluminum alloy template edge through holes. The protrusion and control button are respectively stuck on both sides of the mesh, wire mesh, adjusting steel plate and aluminum alloy template edge.

[0005] Furthermore, the protrusion is a wedge-shaped structure with an inclined surface, with a pointed end and a thick end at both ends. The control rod is connected to the thick end face of the protrusion, and the pointed end of the protrusion is close to the end of the fixing pin. The two ends of the telescopic guide rod are fixed to the side of the protrusion away from the inclined surface and the fixing plate, respectively. The inclined side of the protrusion extends out of the limiting hole and slides in connection with the side wall of the fixing pin.

[0006] Furthermore, the aluminum alloy template has a rectangular structure, including a rectangular web, edge plates located on the outer periphery of the rectangular web, and reinforcing ribs located between opposite edge plates.

[0007] Furthermore, the adjusting steel plate is a strip plate, the length of which is the same as the length of the adjacent plate, and the width of the adjusting steel plate is greater than the width of the adjacent plate.

[0008] Furthermore, a connecting line is provided between the fixing component and the adjusting steel plate, and multiple fixing components are distributed and fixed to the adjusting steel plate at the through hole position through the connecting line.

[0009] Compared with the prior art, this utility model has the following features and beneficial effects: This invention, by setting an adjustable steel plate and changing the number of turns of the wire mesh wrapped around it, can flexibly adapt to pre-reserved openings in composite slabs of different sizes, eliminating the need for on-site processing and reducing construction costs. The adjustable steel plate matches the through holes of the adjacent plate, and the fasteners are prevented from being lost via connecting wires. The fasteners can be inserted and removed simply by pressing a control button, simplifying installation steps, shortening installation time, and increasing installation efficiency. The double-layer protective structure of wire mesh and protective netting effectively prevents personnel from falling and objects from dropping, ensuring protective stability. After use, pressing the control button pushes the protrusion to retract, allowing the fasteners to be removed for disassembly and recycling, facilitating repeated use. It meets green construction requirements and is characterized by safety and applicability, possessing significant promotional and practical value. Widespread application will generate substantial economic benefits. Attached Figure Description

The adjusting steel plate 2 is aligned with the adjacent edge plate on the opposite side of the aluminum alloy template 1, and the through holes 5 of the two are aligned. The edge of the wire mesh 3 is wrapped around the adjusting steel plate 2, and the number of wrapping turns is adjusted to cover the opening. Then, the net 4 is placed below the wire mesh 3, and the edge is aligned. Press the control button 10 of the fixing component 6 to retract the protrusion into the limiting hole. The fixing component 6 is then passed through the through holes 5 of the net 4, wire mesh 3, adjusting steel plate 2, and adjacent edge plate in sequence. The control button 10 is released, and the protrusion extends under the action of the compression spring 11, and is respectively locked on both sides of the component with the control button 10 to achieve fixation. Check whether the fixing of each component is firm and whether the wire mesh 3 and net 4 cover the opening completely. If the opening size is adjusted, the fixing component 6 can be disassembled, the number of wrapping turns of the wire mesh 3 can be readjusted, and then it can be fixed again.
