[0026] The traditional method of protecting horizontal openings is to cover them with wooden boards. When materials are transported through the openings at the construction site, workers are required to remove the wooden boards and move them back after the materials are transported. Frequent movement of wooden boards is time-consuming and labor-intensive, resulting in low construction efficiency.

[0027] The utility model proposes a protective device for a horizontal opening 40 of a building, comprising a template 10, a support rod 20 and a protection plate 30. The template 10 is arranged around the edge of the opening 40 and is used to block the concrete around the opening 40. There are multiple support rods 20, which are arranged at intervals along the longitudinal direction. Each support rod 20 extends along the transverse direction, and the two ends of each support rod 20 pass through the opposite sides of the template 10 and extend into the concrete on the corresponding side. The protection plate 30 is connected to the side of the template 10 facing the opening 40. The protection plate 30 can be extended to an expanded state or contracted to a folded state along the longitudinal direction, and the protection plate 30 is placed on the multiple support rods 20 when extended to the expanded state and blocks the opening 40.

[0028] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The front-to-back direction is the longitudinal direction. Figure 1 and Figure 2The left and right directions in the figure are the horizontal directions. The template 10 serves as the boundary of the opening 40. The protective device proposed in the technical solution is arranged before the concrete structure around the opening 40 is poured, so that the concrete is blocked at the periphery of the opening 40 by the template 10 during the concrete pouring. When the concrete solidifies to form the opening 40, the template 10 is fixedly connected to the concrete through the support rod 20 penetrated thereon. The protective plate 30 is connected to the template 10 and can be extended and retracted in the front-rear direction. The opening 40 can be opened and closed by the extension and retraction of the protective plate 30.

[0029] The protective device for the horizontal opening 40 of a building proposed in the utility model is provided by burying a plurality of support rods 20 in the concrete around the opening 40, each support rod 20 being passed through the template 10, so that the template 10 is fixed to the opening 40 through the support rods 20, so that the template 10 blocks the concrete around the opening 40, and ensures that the concrete solidifies and forms according to the preset size. By connecting the protective plate 30 to the template 10, the protective plate 30 is extended longitudinally to the unfolded state, so that the protective plate 30 is supported on the plurality of support rods 20, and the opening 40 is blocked by the protective plate 30 to protect the opening 40; when the protective plate 30 affects the on-site construction, the opening 40 can be opened by shrinking the protective plate 30 longitudinally to the folded state, and the unfolding and shrinking operation of the protective plate 30 is simple and less time-consuming, which effectively improves the construction efficiency.

[0030] In one embodiment, the template 10 includes four side panels 11 connected end to end in sequence, the four side panels 11 are arranged around the outer periphery of the opening 40, two oppositely arranged side panels 11 extend longitudinally, and the other two side panels 11 extend transversely, and each support rod 20 passes through the two side panels 11 extending longitudinally, and one of the side panels 11 extending transversely is connected to the protective plate 30 on the side facing the opening 40.

[0031] See also Figure 1 The opening 40 is a rectangular opening 40, and the edges of the opening 40 correspond to four side panels 11 respectively, and the four side panels 11 are connected to form the template 10. Each support rod 20 is passed through the two side panels 11 on the left and right sides, so that the wooden board is fixed to the concrete structure around the opening 40 through multiple support rods 20, ensuring that the protective device is firmly connected to the concrete structure around the opening 40.

[0032] In one embodiment, a guide plate 50 is connected to each side panel 11 extending longitudinally. The guide plate 50 is connected to the side of the side panel 11 facing the opening 40, and the guide plate 50 extends longitudinally. The top surface of the guide plate 50 forms a guide platform. The protective plate 30 can slide along the guide plate 50 to extend to an expanded state or slide and shrink to a folded state, and the protective plate 30 is supported on the guide platform when sliding along the guide plate 50 to extend to the expanded state.

[0033] See also Figure 1 and Figure 3 The two guide plates 50 are connected to the two side plates 11 on the left and right sides, respectively. Each guide plate 50 is connected to the upper part of the side plate 11, and the top surfaces of the two guide plates 50 form two guide platforms extending in the longitudinal direction. When the protective plate 30 is extended, the left and right sides of the protective plate 30 are respectively slidably matched with the two guide platforms, so that the guide plates 50 provide guidance for the protective plate 30 during the extension or shortening process of the protective plate 30, and after the protective plate 30 is extended to the unfolded state, the two guide platforms provide support for the protective plate 30 to ensure that the protective plate 30 provides protection for the opening 40.

[0034] In one embodiment, the two side panels 11 extending laterally are respectively a first side panel 11111 and a second side panel 11211, the protective panel 30 is connected to the first side panel 11111, a buckle 31 is connected to the end of the protective panel 30 facing away from the first side panel 11111, and a slot 1121 for engaging with the buckle 31 is provided on the second side panel 11211.

[0035] See also Figure 1 The first side plate 11111 is located at the front side, the second side plate 11211 is located at the rear side, the protective plate 30 is connected to the rear side of the first side plate 11111, and a buckle 31 is provided at the rear end of the protective plate 30. When the protective plate 30 is extended backward to the unfolded state, the buckle 31 is snapped into the slot 1121 on the second side plate 11211 to fix the protective plate 30 at the opening 40, ensuring that the protective plate 30 blocks the opening 40.

[0036] In one embodiment, rollers 12 are rotatably connected to the two side plates 11 extending in the longitudinal direction. The rollers 12 extend in the transverse direction. The protective plate 30 is wound around the two rollers 12 during the process of being contracted in the longitudinal direction to a folded state.

[0037] It is worth noting that the roller 12 is vertically connected to the corresponding side panel 11, and the roller 12 is located at the front end of the side panel 11. When the protective plate 30 retracts forward, the roller 12 rotates to wrap the protective plate 30 around the roller 12, so that the protective plate 30 retracts to a folded state, so that the protective plate 30 occupies a smaller space.

[0038] In one embodiment, the two side plates 11 extending in the longitudinal direction are connected to a connecting shaft extending in the transverse direction, and each roller 12 is rotatably sleeved outside the corresponding connecting shaft. The connecting shaft provides support for the roller 12 sleeved thereon, so that the protective plate 30 is stably wound around the roller 12 when in a folded state.

[0039] In one embodiment, the top of the template 10 extends in a direction away from the opening 40 to form an extension portion, and the extension portion is covered on the concrete.

[0040] It can be understood that the top of the template 10 extends outward from the opening 40 in an L shape, and the extension is supported on the top of the concrete structure outside the opening 40, so that the template 10 can be supported at the opening 40, thereby ensuring that the protective device is stably installed at the opening 40. In addition, the extension can block the gap between the template 10 and the concrete structure outside the opening 40, preventing dust and other debris from falling into the gap during the construction process, and keeping the concrete structure outside the opening 40 clean.

[0041] In one embodiment, the support rod 20 is a steel bar, and the ends of the steel bar are pre-buried in the concrete on the corresponding side. It can be understood that the steel bar and the concrete structure around the opening 40 are cast together, so that the two ends of the steel bar are firmly buried in the concrete structure on the opposite sides, ensuring the close connection between the steel bar and the concrete structure, thereby improving the stability of the protective device.

[0042] In one embodiment, the end of the steel bar is embedded in the concrete on the corresponding side to a depth of not less than 10 cm to ensure that the steel bar has sufficient bonding strength with the concrete structure, thereby ensuring that the protective device is firmly installed in the opening 40 .

[0043] In one embodiment, the protective plate 30 is an aluminum plate. The protective plate 30 and the template 10 are connected to the concrete structure around the hole 40 through the support rod 20. The protective plate 30 is an aluminum plate, so that the protective plate 30 has a light weight. The support rod 20 can provide support for the template 10 and the protective plate 30, and it is convenient to load and unload the protective plate 30. The protective plate 30 has good strength and can provide sufficient strength to block the hole 40 to protect the hole 40.
