Description

Technical Field

[0001] The utility model relates to a protective device, in particular to a protective device for an edge hole. Background Art

[0002] Door openings near elevators and balconies are among the most common and difficult-to-control safety hazards at construction sites, and are key areas of prevention and control. Currently, construction sites often use standardized protective fences or steel pipe protective railings for protection. The aforementioned two forms of protective devices, due to their fixed form and style, will hinder construction work such as wall plastering and floor pouring while providing protection. Construction workers often choose to dismantle the protective facilities to facilitate temporary construction, and at the same time, they cannot restore the protective facilities in time after the construction is completed, posing a major safety hazard to the site.

[0003] In addition, most of the existing protective devices adopt a fixed height form. For example, Chinese patent CN116290864A disclosed a protective device for edge openings and its use method on June 23, 2023, which includes a connecting mechanism, the connecting mechanism is connected to a protective mechanism; the connecting mechanism includes a connecting rod connected to the edge opening; the protective mechanism includes a telescopic member; the two ends of the telescopic member are respectively connected to the protective mechanisms on both sides of the edge opening. However, this technical solution cannot implement the height adjustment of the guardrail, and there are also safety hazards for tall construction workers.

[0004] Therefore, there are above-mentioned various inconveniences and problems in the known side door opening guardrail mode. Utility Model Content

[0022] The present invention is further described below in conjunction with the embodiments and the accompanying drawings. Example

[0023] The utility model discloses a protective device for an edge opening, which comprises a fixed plate and a movable plate.

[0024] Figure 1 This is a schematic diagram of the L-shaped plate structure of an embodiment of the utility model. Figure 2 for Figure 1 The fixed plate is an L-shaped plate, which is provided with a fixed side plate and a movable side plate. The fixed side plate is a long strip plate 3, and a fixing hole 2 is provided in the middle of the long strip plate. The movable side plate 1 is provided with three placing holes 6 that can adjust the upper and lower positions.

[0025] The movable plate is a rectangular steel wire mesh plate 4, and a horizontal round steel 5 is fixed to each of the four corners of the rectangular steel wire mesh plate;

[0026] Wherein: when the protective device is in use, a fixing plate is arranged on both sides of the edge opening, the fixing plate is fixed to the wall with screws, and the rectangular wire mesh plate cooperates with the fixing plate to place the horizontal round steel 5 in the corresponding placement hole 6.

[0027] The utility model is a fixed type height-adjustable vertical edge opening protection device, which consists of four height-adjustable fixings and a protective enclosure. The fixings consist of a 1cm thick, 20cm long, 5cm wide iron plate (with a bolt hole in the middle), and a 1cm thick, 20cm long, 8cm wide iron plate (with a three-level height-adjustable limit opening in the middle, and the vertical spacing of the limit opening is 6cm). The two iron plates are welded to form an "L" shape. The protective enclosure frame is welded from 3cm×3cm square steel, with a steel mesh in the middle and a 50cm high footboard at the bottom. The height of the protective enclosure is 1.8m, the width is 1.5m, and a section of round steel is horizontally welded at the four corners of the protective enclosure.

[0028] The installation method of the fixed height-adjustable vertical edge opening protection device of the utility model is as follows: four fixing parts with adjustable functions, two of which are set at the top and two at the bottom, and the vertical spacing of the fixing parts is 1.8m. The round steels at the four corners of the protective enclosure are first inserted into the four fixing parts, and then the four fixing parts are fixed to the wall by triangular head bolts, so that the protective enclosure is fixed and cannot be removed at will.

[0029] Figure 3 The following is a schematic diagram of the use status of the edge opening protection device of the embodiment of the utility model. The method of using the fixed height-adjustable vertical edge opening protection device of the utility model is as follows: the height of the bottom of the protective enclosure from the ground is selected by placing the round steel on the fixing part at different adjustable limit opening positions, which is convenient for on-site floor construction. At the same time, when the wall is painted, since the fixing part is fixed with a triangular head bolt, the operator cannot easily remove the protective enclosure, which plays an effective protection role.

[0030] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
