Abstract

The invention discloses a channel lateral stand column protection device and belongs to the field of protective devices. The channel lateral stand column protection device has the beneficial effects that protection is reliable and cost is low. According to the technical scheme, the channel lateral stand column protection device comprises a stand column; the circumferential ring of the stand column is sleeved with an inner shell in a penetrating mode; the cross section of the inner shell is in a groove shape, and a groove-shaped opening is outward; the inner shell surrounds the stand column by a circle in a closed mode; the inner shell is also sleeved with a circle of outer shell in a penetrating mode; the outer shell is the same as the inner shell in shape; the external contour of the outer shell is slightly greater than the groove-shaped opening; the upper and lower groove edges of the outer shell are arranged on the upper and lower faces of the upper and lower groove edges of the inner shell; the groove edges of the inner shell and the outer shell coincide partially; the cavity between the inner shell and the outer shell is used for containing an air bag the same as the cavity in shape and filled with high-pressure air. The channel lateral stand column protection device is suitable for columnar building devices on the channel side.

Description

Channel side protection device of column

Technical field

The invention belongs to protector field, specifically refer to a kind of channel side protection device of column.

Background technology

Build the scraping that often can be subject to the vehicles at the building such as column of channel side even collide and damage, the bridge pier of such as road overpass, the bridge pier etc. at rivers navigation channel place, many such columns are protected by additional one deck or a circle concrete cover, the technical measures then adopting too complicated cost high had, what have does not then take any measure, because many measures are all rigidly fix setting, they still can not ensure the safety of column preferably while giving certain protective capacities, violent collision still can penetrate overcoat and arrive column body, and the negative effect of the using function paralysis of the whole building that the damage of column causes is huge beyond doubt, the protector of effective easy construction with low cost and safeguard procedures are taked to seem very urgent.

Summary of the invention

Object of the present invention provides a kind of channel side protection device of column, and it can solve above-mentioned safety problem more thoroughly.

Technical scheme of the present invention realizes like this, it comprises column, described column border wears a cross section and is flute profile and the outside inner casing of flute profile notch, inner casing encloses in closed around column one, also the identical but shell that the bigger notch of gabarite is relative of a loop-shaped is coated with outward at inner casing, the upper and lower trough rim of shell be placed in the upper and lower trough rim of inner casing above and below and the trough rim of inside and outside shell overlap, be equipped with one in the cavity between inside and outside shell and be same as cavity shape and be full of the air bag of pressure-air.

The invention has the beneficial effects as follows: available buffer acts on the impact force on shell, column provides effective protection.

Accompanying drawing explanation

Fig. 1 is the plan view of the design's protector.

Fig. 2 is the cross section view of inside and outside shell in the design's protector.

Fig. 3 is top plan view.

In each figure, 1 is column, and 2 is shell, and 3 is air bag, and 4 is inner casing.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Fig. 3, wear a cross section in column 1 border and be flute profile and the outside inner casing 4 of flute profile notch, it encloses the circle in closed around column 1 one, also wear that a loop-shaped is identical but gabarite is bigger and the shell 2 that the notch of notch and inner casing is just right inner casing 4 is outer, shell upper, lower trough rim is placed in the upper of inner casing, lower trough rim above and below and the trough rim of inside and outside shell overlaps some and all do not overlap, as Fig. 2, shown in Fig. 3, in the cavity formed between relative inside and outside shell, (shape of cross section is like rectangle) is equipped with the air bag 3 that is same as cavity shape, air bag is filled with pressure-air by the valve on it.When there being impulsive contact force to act on shell, air bag in it can to giving flexibility but the support of brute force, the trough rim not exclusively overlapped between inside and outside shell can occur because of stressed to move relative to misfit, and buffer release impulsive contact force relatively slowly, the safety for column provides protects more reliably.The material of related air bag, the additional Kev of more ageing-resistant butyl rubber can be adopted to draw tissue layer, the air bag that this composite material makes can bear hundreds of atmospheric pressure, by this can the counteracting number ton heavy automobile of uniform force can not rigidity damage column body with the frontal collisions of 10m/s (36 km speed per hour); Air bag can interact with inside and outside shell and play more reliable protective action as interior cover, inside and outside shell can carry out welding production according to the concrete shape of round or square (shape of cross section) of column, appearance for air bag easy for installation can be made the cushion of squarely and be not suitable for directly being made ring shape (because being not too conveniently set to obviously on column like that), after the air bag of suitable size being filled some gas less before crust of the device closeout device in place in inner casing groove after refill and be set up shell, be then filled with the air of enough pressure.The cost of the design in the protector that can provide equal bump shield power is minimum, and construction equipment also easy saving trouble saves time.

Claims

1. a channel side protection device of column, it comprises column, it is characterized in that described column border wears a cross section and is flute profile and the outside inner casing of flute profile notch, inner casing encloses in closed around column one, also the identical but shell that the bigger notch of gabarite is relative of a loop-shaped is coated with outward at inner casing, the upper and lower trough rim of shell be placed in the upper and lower trough rim of inner casing above and below and the trough rim of inside and outside shell overlap, be equipped with one in the cavity between inside and outside shell and be same as cavity shape and be full of the air bag of pressure-air.
