Description

A kind of high speed highway guardrail upright post cap

Technical field

The utility model relates to a kind of speedway protective equipment, is specifically related to the cap on the high speed highway guardrail upright post.

Background technology

For security needs, the speedway both sides are equipped with protective guard, with the collision and the absorption collision energy of opposing vehicle.Protective guard is common corrugated beam barrier, cable guardrail, concrete guardrail etc., no matter which kind of guardrail includes equally distributed many steel pipe posts, column is cylindrical, and the column bottom is buried in roadbed, and top is arranged in the speedway both sides.For preventing in the stud cylinder ponding etch roadbed and corrosion column, need on column, install cap additional, immersion that so both can rain cover makes column seem attractive in appearance again.Existing guardrail cap usually with peg graft or the mode spiral-lock of socket in the upper end of fence post, because cap is the guardrail cap to be fixed on the fence post with cooperating of fence upright upper port respective surfaces by its interface position, so planting design takes off easily, simultaneously again because existing cap is steel, be easy to become assistant's target of lawless person and be removed and steal, thereby cause greater loss.Therefore various highway guard rail upright post cap with anti-theft feature has appearred, be called " highway guard rail upright post cap ", the patent No. as name and be the Chinese utility model patent of " 200410010151.1 " a kind of cap disclosing, the center is provided with vertical fastening bolt down in the cap shell of this cap, be installed with on the fastening bolt and be used for drawing the positioning cap support that connects with connecting bolt, though this cap theftproof is good, but complex structure, trouble is installed, and the cost height, be difficult to promote.

Summary of the invention

At existing high speed highway guardrail upright post cap above shortcomings, the purpose of this utility model provide a kind of simple in structure, easy for installation, cost is low, have the high speed highway guardrail upright post cap of anti-theft feature.

The technical solution of the utility model is achieved in that a kind of high speed highway guardrail upright post cap, and it comprises the rain visor of a circle, is provided with at rain visor bottom centre position to be used to put into the plunger that column plays the role of positioning.Described plunger is cylindrical shape, cylindrical or triangle.

Further improve being, described rain visor and plunger are the integrative-structure that cement forms.

The utility model processing simple in structure, easy, easy for installation, only need that the plunger of cap is directly put into steel pipe post and get final product, and because its material is cement, with low cost, there is not other value, can not become lawless person's theft target, therefore have anti-theft feature naturally.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, from the figure as can be seen, high speed highway guardrail upright post cap of the present utility model, it comprises the rain visor 1 of a circle, be provided with at rain visor 1 bottom centre position and be used to put into the plunger 2 that column plays the role of positioning, promptly plunger 2 is concentric with rain visor 1.Described plunger 2 both can be a cylindrical structure, can be structures such as column structure, triangle also, can also be that other can realize the structure of locating, as be positioned at the several reference columns on the same circumference.Only reflected this a kind of structure of cylinder among the figure, because other structure is also very simple, the Therefore, omited corresponding view.Because iron and steel class material easily becomes assistant's target of thief, so the utility model selection is cement, and rain visor and plunger is one-body molded by mould.

Because the cement cap can not stolen, so the utility model does not have retaining mechanism and fastener, just because of this, the structure of this cap is just simplified, thereby reduce cost, and processing and installation are become easily, only need during installation that the plunger 2 of cap is directly put into steel pipe post 3 and get final product, as shown in Figure 3.
