Description

A steel through-the-heart lock-key combined safety guardrail

Technical Field

The utility model belongs to the technical field of construction safety, and more specifically relates to a steel through-the-core lock-key combined safety guardrail.

Background Art

In construction projects, temporary protection is generally provided by steel pipes or shaped protection. This type of protection is affected by the material itself and factors on the construction site, and the recycling and reuse rate is not high. In the construction process of construction projects, due to the large number of construction procedures and complicated processes, many tasks are cross-operated by different construction personnel, and our temporary protective railings are often damaged after they are erected. Since the safety awareness of the workers is generally not high, they rarely take the initiative to restore after the damage, and some protection is difficult to repair once it is damaged due to material reasons. Due to design requirements, some building edges and openings have special shapes, arcs, etc., and it is difficult to achieve fully enclosed protection with conventional protection. In order to save costs, some projects use unqualified protective products, or even perfunctorily handle them, leaving safety hazards.

Summary of the invention

The utility model provides a steel through-lock key combined safety guardrail, which solves the problems raised in the above background technology that due to the generally low safety awareness of workers, they rarely take the initiative to restore after damage, and it is difficult to repair some protections once they are damaged due to material reasons; some building edges and openings may have special shapes, arcs, etc. due to design requirements, and conventional protection is difficult to achieve fully enclosed protection for them.

In order to solve the above problems, the utility model is implemented by adopting the following technical solution: the safety guardrail comprises a triangular fixed belt disc bracket base (1), which is fixed on the concrete structure on the ground by expansion bolts;

A perforated crossbar (2) and a vertical bar (4) connected to the base via a special lock-key type fixing piece (3);

The perforated cross bar (2) is connected to the perforated footboard (5) via a steel wire rope.

Furthermore, the perforated crossbar, vertical bar and perforated footboard constitute a basic guardrail assembly unit, the spacing between them is 500 mm, and the length of the guardrail assembly unit is 0.6 m or 1.2 m.

Furthermore, the vertical pole (4) is arranged through the perforated cross bar (2) to enhance the overall stability of the guardrail.

Furthermore, the special lock-key type fixing member (3) is assembled with a plurality of guardrail assembly units to form guardrails of different lengths.

Furthermore, the triangular fixed belt disc support base (1) is provided with a plurality of holes for selection, and the erection angle of the guardrail is selected according to needs.

Furthermore, the perforated cross bar (2), the vertical bar (4) and the perforated footboard (5) are all made of steel material.

Beneficial effects of the utility model:

The utility model has a simple structure and adopts a triangular fixed belt disc bracket to connect the shaped railings. It has good fastening effect, is easy to install and disassemble, has adjustable installation angle, reasonable design, is convenient and efficient, and is suitable for temporary or permanent protection of "four openings and five edges" such as various elevator shaft openings, stair openings, and balcony edges. It can be reused, and the protection height and length can be assembled according to the actual situation on site. It can be set up at openings and edges of various shapes, which expands the scope of application, greatly reduces construction costs, and improves work efficiency.

DETAILED DESCRIPTION

The present invention will be described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Figures 1-3, the steel through-hole lock-key combined edge protection railing includes a triangular fixed disc bracket base 1, a perforated cross bar 2, a special lock-key fixing 3, a vertical pole 4, and a perforated footboard 5. The triangular fixed disc bracket base 1 is fixed to the concrete structure base on the ground by expansion bolts. According to the on-site protection height requirements, the two ends of the perforated cross bar 2 are connected to the bracket perforated disc through the vertical pole 4 through the special lock-key fixing 3. The perforated footboard 5 is fixed to the perforated cross bar 2 by a steel wire rope. The perforated cross bar 2, the vertical pole 4 and the perforated footboard 5 must be painted with red and white warning paint with a spacing of 500mm to form a basic guardrail assembly unit. The guardrail assembly unit length can be controlled at 0.6m or 1.2m. According to the on-site protection requirements, assemble steel through-hole lock-key edge protection railings of different lengths and angles.

The utility model has a simple structure, uses a triangular fixed disc bracket base, and is matched with a freely assembled protective railing. It has a good fastening effect, is easy to install and disassemble, and is convenient and efficient to construct. It is suitable for temporary or permanent protection of "four openings and five edges" such as various elevator wells, stairways, and balcony edges. The tools can be reused, saving construction costs, improving construction efficiency, and reducing safety hazards in construction.

It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
