Problems solved by technology

[0002] Chinese patent document CN101265694A discloses a spray-painted steel guardrail, including uprights, upper crossbars, lower crossbars and vertical bars. There are two ways to connect the rod: one is the way of welding one piece, which has the advantages of fast processing, high efficiency and firm structure, but the disadvantage is that it is inconvenient to transport and install; the other is the way of plug-in components. Its advantage is that the transportation and installation of various accessories are more convenient, but the disadvantage is that it is not firm and easy to fall off
Although the guardrail solves the problem of being weak and easy to fall off, when installing, it is necessary to weld and fix the clamping piece and the convex piece in the vertical rod tube, that is, it needs to be installed live, so there is still the disadvantage of inconvenient installation
[0004] The above two kinds of guardrails all have the following two disadvantages: (1) the upper and lower cross bars are connected to the columns through connecting sleeves. On the one hand, this connection method is also not firm and easy to fall off; on the other hand, this connection method also leads to It protrudes above the upper cross bar, which will give passers-by and motor vehicle drivers a complicated feeling
(2) The reflective film is all pasted on the vertical pole, which is not conducive to the viewing angle of the motor vehicle driver on the one hand, and on the other hand increases the amount of reflective film used, resulting in higher cost
This guardrail solves the above-mentioned problems by making the inner column, the upper cross bar, the lower cross bar and the vertical bar into an integral part, so there are still the disadvantages of inconvenient transportation and installation of the integral part
[0006] The above three guardrails are all steel guardrails, which are easy to rust

Embodiment 1）

[0053] see figure 1 , the present embodiment takes two guardrail units as an example, including three columns 1, two upper rails 2, two lower rails 3 and two sets of vertical bars 4, each group of vertical bars has seven. Column 1 includes two side columns and a middle column. The column 1, the upper cross bar 2, the lower cross bar 3 and the vertical bar 4 are all made of aluminum alloy. Column 1, upper rail 2, lower rail 3 and vertical bar 4 are all hollow structures, wherein column 1 is provided with jacks suitable for inserting lower rail 3, and upper rail 2 and lower rail 3 are also provided with There are ribs.

[0054] see figure 2 with image 3 The vertical bar 4 is a hollow structure with four through holes 42, and the upper and lower ends of the vertical bar 4 are connected with the upper cross bar 2 and the lower cross bar 3 through a stamping connector 5.

[0055] see Figures 4-1 to 4-4 The stamped connector 5 includes a main body 51 and inner protrusions 5...

Embodiment 2）

[0063] See Figure 13 to Figure 16 , the guardrail of this embodiment is basically the same as that of Embodiment 1, the difference is that: among the vertical rods 4 between the two columns 1, the two vertical rods 4 at both ends and the vertical rod 4 in the middle pass through the fixing assembly 8 is fixed between the upper cross bar 2 and the lower cross bar 3.

[0064] The fixing assembly 8 includes a steel pipe 81 , a threaded sleeve 82 , a square sleeve 83 and a fastening screw 84 .

[0065] The steel pipe 81 can be a round steel pipe or a square steel pipe, and this embodiment is a round steel pipe.

[0066] The upper end of steel pipe 81 is welded and fixed with square sleeve 83, and the upper surface of square sleeve 83 is suitable for inserting in the stamping hole of upper cross bar 2, and the lower end of steel pipe 81 is provided with external thread, and the upper end of threaded sleeve 82 is provided with steel pipe 81 lower end. The external thread is compa...

Abstract

The invention discloses a combination road fence which comprises a pillar, an upper horizontal rod, a lower horizontal rod and a vertical rod. The left end and the right end of the upper horizontal rod are connected with the pillar through a pillar nut. The pillar nut comprises an underneath nut seat, an over nut cover and a connection portion located between the nut seat and the nut cover. A first screw hole used for fixedly connecting the pillar nut to the pillar is formed in the nut seat of the pillar nut. The section of the nut cover of the pillar nut is identical with the section of the upper horizontal rod in shape and size and the upper horizontal rod can be suitably inserted into the nut cover. The connection portion of the pillar nut is provided with a second screw hole used for fixedly connecting the upper horizontal rod and the pillar nut. According to the combination road fence, the upper horizontal rod is connected with the pillar through the pillar nut. On one hand, connection becomes firm, and on the other hand, installation can be carried out without electricity and operation difficulty on an installation spot is reduced.

Description

technical field [0001] The invention belongs to the technical field of road traffic facilities, and in particular relates to a combined road guardrail. Background technique [0002] Chinese patent document CN101265694A discloses a spray-painted steel guardrail, including uprights, upper crossbars, lower crossbars and vertical bars. There are two ways to connect the rod: one is the way of welding one piece, which has the advantages of fast processing, high efficiency and firm structure, but the disadvantage is that it is inconvenient to transport and install; the other is the way of plug-in components. Its advantage is that the transportation and installation of various accessories are more convenient, but the disadvantage is that it is not firm and easy to fall off. [0003] As an improvement to the above shortcomings, the Chinese patent document CN202108017U discloses a clamping steel guardrail, including a column, an upper rail, a lower rail and a vertical bar, and the up...
