Description

Technical Field

[0001] This utility model belongs to the technical field of safety protection devices, specifically relating to a tool-type protective device for openings in composite slabs. Background Technology

[0002] Composite slabs are composed of precast slabs and cast-in-place reinforced concrete. They have good integrity and a flat surface, making them easy to decorate. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity. They are a commonly used building material in the construction industry and are widely used in various construction projects.

[0003] A slab opening refers to a hole pre-reserved or drilled in a slab to meet specific construction or functional requirements. However, when workers need to install edge beams, there is a large opening behind their work position, which poses a risk of falling from a height.

[0004] Based on the above, a protective device is needed to prevent falls from heights. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a tool-type protective device for the opening of composite slabs.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A tool-type protective device for openings in composite slabs includes two telescopic fixed side rods placed in parallel, a plurality of telescopic planar rectangular tubes installed between the two telescopic fixed side rods, and a protective net installed on the lower side of the telescopic planar rectangular tubes;

[0008] The telescopic fixed side rod is connected to a U-shaped seat at its tail end. The U-shaped seat has a slot. A pressure rod is placed between the two U-shaped seats through the slot. A vertical pole is hinged to each of the two U-shaped seats. An upper telescopic railing and a lower telescopic railing are installed between the two vertical poles. Both the upper and lower telescopic railings are welded with ear plates. A support rod is hinged to the upper telescopic railing through the ear plates.

[0009] Furthermore, there are four telescopic planar rectangular tubes, which are evenly installed between the two telescopic fixed side rods. This design ensures support strength and good load-bearing effect.

[0010] Furthermore, the protective net is a foldable protective net, a design that prevents it from drooping when stored.

[0011] Furthermore, the U-shaped seat is equipped with a pin screw, and a double-ring tension spring is installed between the pin screw and the pressure rod. This design, once placed, causes the upright to move backward under the effect of the double-ring tension spring, applying pressure to the support rod, so that the end of the support rod can firmly abut against the contact surface, thereby ensuring the force-blocking effect of the upper and lower telescopic railings.

[0012] Furthermore, the support rod is a telescopic support rod equipped with a locking screw. This design allows the length of the support rod to be adjusted, which is beneficial for contacting objects at different positions, thereby ensuring support for the upper and lower telescopic railings. The locking screw ensures that the length of the support rod will not change under force after the length is adjusted.

[0013] The beneficial effects of using this utility model are as follows:

[0014] The structural design of this utility model, with the characteristics of telescopic fixed side rods and telescopic planar rectangular tubes, can adapt to the covering of composite slab openings of different specifications and sizes, with good adaptability. When used with protective nets, it can prevent workers from falling from the openings.

[0015] By adopting the structural design of this utility model, while the protective net serves to block the opening and provide protection, the upright poles and the upper and lower telescopic railings installed between them, together with the support poles on the rear side, can also prevent workers from falling into another opening when they step back, thus further enhancing the safety effect.

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, the present invention provides a tool-type protective device for the opening of a composite slab, comprising two parallel telescopic fixed side rods 1, a plurality of telescopic planar rectangular tubes 2 installed between the two telescopic fixed side rods 1, and a protective net 3 installed on the lower side of the telescopic planar rectangular tubes 2.

[0025] The end of the telescopic fixed side rod 1 is connected to a U-shaped seat 4. The U-shaped seat 4 has a slot 5. A pressure rod 6 is placed between the two U-shaped seats 4 through the slot 5. Uprights 7 are hinged to both U-shaped seats 4. An upper telescopic railing 8 and a lower telescopic railing 9 are installed between the two uprights 7. Ear plates 10 are welded to both the upper telescopic railing 8 and the lower telescopic railing 9. A support rod 11 is hinged to the upper telescopic railing 8 through the ear plate 10.

[0026] In this implementation case, when using a tool-type protective device for a composite slab opening, the telescopic fixed side rod 1 and the telescopic planar rectangular tube 2 are stretched to match the length of the corresponding side of the opening. This allows for a simple and quick way to block the upper side of the opening. When the telescopic fixed side rod 1 and the telescopic planar rectangular tube 2 are stretched, the protective net 3 changes accordingly, covering the opening. This enhances the fall prevention effect and also prevents small objects or tools from falling and injuring people, thus improving safety performance.

[0027] Furthermore, the upright pole 7 is made vertical, and then the support rod 11 is removed from the ear plate 10. The end of the support rod 11 is placed against the edge of another opening or the corresponding contact object. At this time, the support rod 11, the upright pole 7 and the placement surface form a triangle, thereby supporting the upright pole 7. This enables the upper telescopic railing 8 and the lower telescopic railing 9 to bear the load and effectively block the impact, preventing workers from falling into another opening when they lean backward.

[0028] It is preferable to have four telescopic planar rectangular tubes 2, which are evenly installed between the two telescopic fixed side rods 1. This design ensures support strength and good load-bearing effect. In fact, the number of telescopic planar rectangular tubes 2 can also be considered according to the specific situation.

[0029] The preferred protective net 3 is a foldable protective net. This design prevents it from drooping when stored. In fact, the choice of protective net 3 can also be considered depending on the specific situation.

[0030] The preferred U-shaped base 4 is equipped with a pin screw 12, and a double-ring tension spring 13 is installed between the pin screw 12 and the pressure rod 6. This design allows the upright 7 to move backward under the effect of the double-ring tension spring 13 after placement, giving pressure to the support rod 11, so that the end of the support rod 11 can firmly abut against the contact surface, thereby ensuring the force blocking effect of the upper telescopic railing 8 and the lower telescopic railing 9. In fact, a structure that ensures that the two ends of the support rod 11 are not easily displaced can also be considered according to the specific situation.

[0031] The preferred support rod 11 is a telescopic support rod equipped with a locking screw. With this design, the length of the support rod 11 can be adjusted, which is conducive to contacting objects in different positions, thereby ensuring support for the upper telescopic railing 8 and the lower telescopic railing 9. The locking screw ensures that the length of the support rod will not change under force after the length is adjusted. In fact, the structure of the support rod 11 can also be considered according to the specific situation.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
