Abstract
The utility model discloses a kind of concrete guardrail and increase structure, be intended to reduce the improvement cost of concrete guardrail, improve the improved barrier propterty of guardrail, make mixed earth guardrail to increase rebuilding construction more convenient.Concrete guardrail is increased structure and is comprised heightening upright post, bracket, crossbeam, stone bolt and fastening bolt, heightening upright post, bracket and crossbeam are all provided with bolt hole, when guardrail is increased, by stone bolt, heightening upright post is anchored in directly over concrete guardrail, bracket is anchored in the concrete guardrail back side, and then with fastening bolt, the opposite side of heightening upright post is fixed on above bracket, finally by fastening bolt, crossbeam is fixed on heightening upright post.
Description
Technical field
The utility model relates to highway traffic safety facility field, particularly relates to a kind of concrete guardrail and increases structure.
Background technology
Along with China's rapid development of economy, Highway Cause development rapidly, many old highways are faced with reorganization and expansion, particularly some road surfaces are through the highway of cover overhaul, its guardrail height major part is not enough, once after vehicle collision, by easily occur thrusting guardrail or cross guardrail and fall down from the bridge serious accident, from the angle of safety, tackle it and transform.Original concrete guardrail is generally removed, and then newly-built by guardrail transformation in the past, which not only adds construction cost, also increases difficulty of construction.Therefore develop a kind of guard bar structure utilizing former concrete guardrail to reach high-protection level, reduce improvement cost, shortening the engineering time, is very necessary.
Utility model content
What the purpose of this utility model aimed to provide a kind of concrete guardrail increases structure, this guard bar structure should make full use of original concrete guardrail, and meets the crashproof requirement of guardrail in current Chinese code of practice, facilitates the transformation and upgrade of guardrail simultaneously, reduce construction cost, shorten the engineering time.
For realizing above-mentioned target, the utility model adopts following technical scheme: the structure of increasing of concrete guardrail is made up of heightening upright post, bracket, crossbeam, stone bolt and fastening bolt, heightening upright post, bracket and crossbeam are all provided with bolt hole, when guardrail is increased, by stone bolt, heightening upright post is anchored in directly over concrete guardrail, bracket is anchored in the concrete guardrail back side, and then with fastening bolt, the opposite side of heightening upright post is fixed on above bracket, finally by fastening bolt, crossbeam is fixed on heightening upright post.
The cross sectional shape of described heightening upright post can be one of them of circle, rectangle, flute profile, T-shaped or H-shaped.
Described crossbeam is arranged along heightening upright post short transverse at a certain distance, and adding high request according to guardrail, can be single-beam, two crossbeam or three crossbeams, and the cross sectional shape of crossbeam can be rectangle, circle, ellipse or trapezoidal one of them.
To sum up, the utility model structure is simple, easy for installation, can effectively reduce guardrail improvement cost, shortens the engineering time.
