the reference numbers in the figures illustrate: 100-upright posts, 110-bolts, 120-vertical long holes, 130-transverse screws, 200-guard rails, 210-splicing rods, 211-oblique long holes, 300-bottom plates, 310-expansion bolts, 400-L-shaped reinforcing plates and 410-folded edges.

Detailed Description

As shown in fig. 1 to 3, a safety barrier for stairs in a construction site comprises a plurality of vertical columns 100 and at least two guard rails 200 installed on the vertical columns, wherein each guard rail 200 is formed by connecting a plurality of sections of hollow splicing rods 210, two adjacent splicing rods 210 are sleeved together and can slide relatively, the splicing rods 210 are provided with a plurality of inclined long holes 211 which are arranged at intervals along the length direction of the splicing rods and parallel to the length direction of the splicing rods, the sleeved parts of the two ends and the middle adjacent splicing rods of the guard rail are connected to the vertical columns through bolts which pass through the inclined long holes, and the vertical long holes 120 through which the bolts pass are formed in the vertical columns 100; the whole guardrail adopts a telescopic structure, the length of the whole guardrail rod and the mounting position of the stand column can be adjusted by increasing or decreasing the number of the splicing rods and sliding the splicing rods between the two adjacent splicing rods, the use is convenient, the disassembly and the assembly are convenient, and the universality is strong.

In this embodiment, the splicing rods have two specifications of which the cross-sectional dimension is one larger and one smaller, the outer cross-sectional dimension of the splicing rod with the smaller specification is slightly smaller than the inner cross-sectional dimension of the larger specification, any two adjacent splicing rods on the guardrail rod are two splicing rods with different specifications, and the splicing rod with the smaller specification is inserted into the splicing rod with the larger specification; therefore, the splicing rods on the guardrail rod adopt two splicing rod interval staggered arrangement modes with different sizes and specifications instead of a structure with gradually reduced size, and the whole strength is better.

In this embodiment, in order to reduce the weight of the vertical column and the splicing rod, the vertical column and the splicing rod both adopt hollow structures, the lower end of the vertical column 100 is welded on a bottom plate 300, the bottom plate is fixed on a building body through an expansion bolt 310, L-shaped reinforcing plates 400 are arranged on the front and rear sides of the lower end of the vertical column 100, a transverse plate of the L-shaped reinforcing plate 400 and the bottom plate 300 are locked together by the expansion bolt, a pair of transverse screws 130 which are arranged up and down are arranged at the lower end of the vertical column 100, and two ends of the transverse screws 130 are locked by nuts after passing through vertical plates of the L-shaped reinforcing plates on both sides; the lower end of the traditional upright post is fixed by welding on the bottom plate, but the welding part has poor strength and is easy to break under stress; so the utility model discloses an add two L type gusset plates, can improve the intensity of stand lower extreme greatly, the security is high.

In this embodiment, the L-shaped reinforcing plate 400 has flanges 410 bent toward and attached to the left and right sides of the pillar at both sides of the vertical plate.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
