Embodiment 1

[0028] like figure 1 , figure 2 As shown in the figure, the present embodiment provides a telescopic safety guardrail on the edge of a bridge construction cover beam, including a foundation pole 1, a first set of poles 2, a first insertion pole 3, a second set of poles 4, and a second insertion pole 5. Reinforcement assembly 6 , fixed vertical rod 7 , movable vertical rod 8 and sleeve 9 .

[0029] like figure 1 , figure 2 As shown in the figure, there are a plurality of basic vertical poles 1 in this embodiment, and a plurality of the basic vertical poles 1 are parallel to each other and vertically arranged to form a rectangular support frame of the protective railing, and the inner side of the lower end of the rectangular support frame abuts against the bridge construction The outer side of the cover beam limb.

[0030] Specifically, there are four basic poles 1 in this embodiment.

[0031] like figure 1 , figure 2 As shown, the first set of rods 2, the first plug r...

Abstract

The invention discloses a bridge construction bent cap edge telescopic safety protection handrail which comprises a foundation vertical rod, a first sleeve rod, a first insertion rod, a second sleeve rod and a second insertion rod. The multiple foundation vertical rods are parallel to one another and are vertically arranged to form a rectangular supporting frame of the protective barrier, and the inner side of the lower end of the rectangular supporting frame abuts against the outer side of the edge of a bridge construction bent cap. The first inserting rod and the first sleeve rod are connected in a sliding mode to form a long side rod, and the second inserting rod and the second sleeve rod are connected in a sliding mode to form a short side rod. The protective barrier is of a telescopic structure formed by mutually connecting the basic vertical rod, the first sleeve rod, the first inserting rod, the second sleeve rod and the second inserting rod; and the long side rods and the short side rods of the protective barrier are formed by movably connecting the inserting rods and the sleeve rods, so that the length and the width or the size of the protective barrier can be adjusted according to the size of the edge of the capping beam in field bridge construction, and the protective barrier is convenient to use.

Description

technical field [0001] The invention relates to the technical field of bridge construction protection facilities, in particular to a telescopic safety guardrail on the edge of a bridge construction cover beam. Background technique [0002] In the construction of cover beam or tie beam in bridge engineering, for the sake of safety, protective devices are usually installed on the edge of the cover beam or tie beam. The existing protective device is built with a fastener-type steel pipe with a diameter of 48mm and a wall thickness of 3.6mm, and the steel pipe is painted with red and white paint as a warning sign. Cover beams or tie beam planes use steel welded steel mesh sheets, and then covered with bamboo springboards for protection. [0003] The existing protective device is very inconvenient to operate, and small components are easy to fall from a high place. Many places on the operating surface of the steel pipe facade guardrail are empty and unprotected, which cannot for...
