Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a novel hidden welded guardrail. Background Art

[0002] Guardrails can be seen everywhere in life. We can see them in residential areas, balconies, roads, green belts, highways, airports, supermarkets, etc. Guardrails play a great role in safety in our lives. Most of the materials of guardrails are aluminum alloy, zinc steel, but there are also wood, stone, concrete, fiberglass, etc.

[0003] The current guardrails are used in balconies or corridors of residential areas, and the existing guardrails are welded with welding guns, which easily leads to the exposure of welding points. Although they are polished and painted for corresponding beautification, the welding points will still affect the overall appearance and cause a lack of aesthetics. Utility Model Content

[0004] In view of the above problems, the utility model provides a new type of hidden welded guardrail, which blocks the welding positions on the top of the supporting railing and the partition bar by cooperating with the appearance shape of the handrail body, thereby not only improving the reliability of the connection, but also improving the aesthetics of the overall appearance.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a new type of hidden welded guardrail, comprising a plurality of supporting rails, a handrail is installed on the top of the plurality of supporting rails, a plurality of spacer bars are arranged between the plurality of supporting rails, a plurality of cross beams are fixed on the spacer bars, wherein arc-shaped decorative pieces are arranged on the surface of two cross beams, and a cross-shaped piece is welded between the cross beam and the supporting rails. The arc-shaped decorative piece and the cross-shaped piece are mainly used to improve the appearance of the guardrails, and at the same time, they can also assist the connection between the cross beam and the supporting rails, so that the three are fixed under the fixed welding of the cross-shaped piece.

[0006] Furthermore, the handrail is provided with a handrail body, the lower surface of the handrail body is formed with a lower bottom surface, the lower bottom surface is provided with a plurality of butt welding grooves, and a hollow groove is formed in the handrail body. The arc-shaped body is cast with both sides of the lower bottom surface in an outward convex style to cover the butt welding groove, so as to cover the welding points at the welding place after the supporting railing and the spacer bar are embedded and welded, so as to avoid being exposed to the outside and affecting the overall appearance of the railing.

[0007] Furthermore, one of the spacer bars penetrates the crossbeam bar, and a plurality of the butt welding grooves correspond to the top of one of the spacer bars and the top of the support railing, and are embedded in welding. Both ends of the crossbeam bar are nested in the side wall of the support railing, and the cross-cross piece is fixed in the square groove formed by the crossbeam bar, the spacer bar and the support railing by welding. Both ends of the crossbeam bar are nested in the side wall of the support railing, which not only realizes the positioning of the crossbeam bar, but also has the cross-cross piece and the arc-shaped decorative piece on and between the crossbeam bars to set the appearance.

[0008] Furthermore, the cross section of the arc-shaped decorative piece is welded to the side of the crossbeam, and the arc-shaped decorative piece is placed relative to the crossbeam to form an elliptical slot. The elliptical slot formed by the relative placement of the arc-shaped decorative pieces and the setting of the distance between the partition bars are also completed through the set appearance to achieve the corresponding beautification treatment.

[0009] Beneficial Effects

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model uses a butt welding groove opened on the lower bottom surface of the handrail body through the support rail and a partition bar that passes through the crossbeam, so that the welding position of the top of the support rail and the partition bar is blocked with the cooperation of the appearance shape of the handrail body. At the same time, the embedded welding method can make the fixation more firm and reliable, and also improve the aesthetics of the overall appearance. BRIEF DESCRIPTION OF THE DRAWINGS
