Description

Technical Field

[0001] This utility model relates to a protective device for reserved holes in buildings, and more particularly to a multi-protection device that can adapt to various sizes of reserved holes in buildings. Background Technology

[0002] Leaving openings in buildings is a common practice in design and construction. However, these openings pose certain safety risks, and if the protective measures fail, they could potentially lead to accidents. These seemingly ordinary openings are actually the source of significant personal safety risks on construction sites.

[0003] Currently, single-layer steel or wooden panels are commonly used for covering, but these structures have fatal flaws. The materials lack sufficient strength and are highly susceptible to displacement and damage during trampling, equipment movement, or material stacking. More seriously, most protective measures have fixed, rigid dimensions. In complex and variable construction environments, facing holes of varying sizes, such protection either fails to provide a tight seal, creating "protective gaps," or requires repeated disassembly and reconstruction. This process itself, lacking temporary protection, becomes a new high-risk period. Every instance of mismatched dimensions and every unprotected opening during fabrication accumulates the risk of falls, while simultaneously causing a huge waste of manpower and materials. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-protection device that can adapt to various sizes of pre-reserved holes in buildings. It can adapt to various specifications of pre-reserved holes in buildings, improve construction safety, and this facility can be reused, saving manpower and materials.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A multi-protection device that can adapt to various building pre-reserved hole sizes includes four frame components, which are connected to each other to form a rectangular frame.

[0007] Each of the frame components includes a main frame and a sub-frame fixedly connected to the main frame, wherein the main frame is provided with a first positioning hole and the sub-frame is provided with a plurality of second positioning holes at equal intervals;

[0008] The sub-frame of the frame component constituting the rectangular frame is inserted into the main frame of the adjacent frame component, and the frame components are fixedly connected by pins that pass through the first positioning hole and the second positioning hole in sequence; and the first positioning hole can be connected to different second positioning holes to adjust the coverage area of ​​the rectangular frame.

[0009] The rectangular frame is fixed with support feet at each of its four corners, and at least one hook for hanging a safety net is fixedly connected to each support foot along its length.

[0010] Furthermore, the support feet are connected to the bottom of the main frame of each of the frame components constituting the rectangular frame by welding.

[0011] Furthermore, each frame component constituting the rectangular frame is provided with a handle, which is welded to the main frame of the frame component.

[0012] Preferably, the number of hooks on the support foot is two, and the four corners of the safety net are hung on four hooks at the same height on the support foot, for a total of two layers.

[0013] Preferably, a plurality of hooks are fixedly provided at the bottom of the main frame of each of the frame components.

[0014] The present invention, by adopting the above technical solution, can achieve the following beneficial effects:

[0015] This invention improves upon existing building pre-reserved hole cover plates, which can only be used once and require remaking each hole size during construction. It reduces the exposure time of safety hazards and the manpower and material resources required for production, improves construction safety, and can also be reused, saving costs.

[0020] like Figures 1-3 As shown, a multi-protection device that can adapt to various building reserved hole sizes is used for temporary protection of building reserved holes. It includes four frame components 2 that are connected by plug-in connection and form a rectangular frame 1 after connection.

[0021] Each of the frame components 2 includes a main frame 3 and a sub-frame 4 fixedly connected to the main frame 3 by welding. The main frame 3 is provided with a first positioning hole, and the sub-frame 4 is provided with a plurality of second positioning holes at equal intervals.

[0022] The sub-frame 4 of the frame component 2 constituting the rectangular frame 1 is inserted into the main frame 3 of the adjacent frame component 2. The frame components 2 are fixedly connected by pins that pass through the first positioning hole and the second positioning hole in sequence. Furthermore, the first positioning hole can be connected to different second positioning holes to adjust the coverage area of ​​the rectangular frame 1. In other words, the second positioning hole of the sub-frame 4 of a frame component 2 can be connected to the first positioning hole of the main frame 3 of the adjacent frame component 2 by pins to form an adjustable telescopic structure, thereby adjusting the coverage area of ​​the rectangular frame 1 to accommodate building pre-reserved holes of different sizes.

[0023] To facilitate the hanging of the safety net 8, support feet 5 are fixed at the four corners of the rectangular frame 1. At least one hook 7 for hanging the safety net 8 is fixedly connected to the support feet 5 along its length. The support feet 5 are welded to the bottom of the main frame 3 of each frame component 2 that constitutes the rectangular frame 1, and are preferably set at the bottom of the main frame 3 at the corner of the frame component 2.

[0024] The support leg 5 has two hooks 7, and the four corners of the safety net 8 are hung on four hooks 7 at the same height on the support leg 5, for a total of two layers; and in order to improve the safety factor, the sides of the two layers of safety net 8 are also connected to a plurality of hooks 7 fixed at the bottom of the main frame 3 of the frame assembly 2.

[0025] To facilitate the picking up, placing and moving of the rectangular frame 1, each frame component 2 constituting the rectangular frame 1 is provided with a handle 6, wherein the handle 6 is welded to the main frame 3 of the frame component 2.

[0026] It should be noted that for rectangular pre-reserved openings with standard dimensions, it is recommended to place the support leg 5 inside the rectangular pre-reserved opening, preferably close to the wall of the rectangular pre-reserved opening. For irregularly shaped pre-reserved openings, the support leg 5 should be placed outside the pre-reserved opening. It is recommended to install a rubber sleeve at the bottom of the support leg 5 to increase the friction between the entire device and the building, making the entire device less prone to movement. Of course, the situation of placing the support leg 5 outside the pre-reserved opening also applies to rectangular pre-reserved openings with standard dimensions.

[0027] In this embodiment, each frame component 2 includes a main frame 3 made of 50mm*50mm*3mm metal square tube, a secondary frame 4 made of 40mm*40mm*3mm metal square tube, and a support leg 5 made of the same specification and material as the secondary frame 4.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any equivalent substitutions and modifications made by those skilled in the art without departing from the guidance of the present utility model should be considered to fall within the protection scope of the present utility model.
