Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 4, the utility model provides a circular crossbeam limit guardrail of bridge, including two pipe crossbeams 1, cast steel stand 2, steel base 3, wherein, through setting up two pipe crossbeams 1, can increase the permeability of limit guardrail, two sides are equipped with the recess about cast steel stand 2, the edge of recess is protruding structure, and cast steel stand 2 passes through the bolt with steel base 3 and fixes in the recess of side, and cast steel stand 2's front is provided with a plurality of semi-annular grooves, and pipe crossbeam 1 partly imbeds among the semi-annular groove, cast steel stand 2's semi-annular groove below is equipped with the strip hole, and cast steel stand 2 is fixed in the recess of side through the bolt that passes the strip hole with pipe crossbeam 1.

As the improvement of technical scheme, the thickness of pipe crossbeam 1 is 10mm, when thickness was 10mm, satisfies limit guardrail anticollision grade and is SB level, effectively protects pedestrian and vehicle safety.

As an improvement of the technical scheme, as shown in fig. 2, a drain pipe 6 penetrating through the steel base 3 is arranged in the steel base, a drain grate 7 is arranged at a water inlet of the drain pipe 6, and a lower port of the drain grate 7 is positioned below the surface height of the bridge pavement layer and is used for timely draining rainwater on the bridge pavement layer and preventing the bridge body from being corroded by water seepage.

As technical scheme's improvement, as shown in fig. 4, pipe crossbeam 1 is equipped with end shrouding 4 in bridge expansion joint department, and end shrouding 4's both ends are entangled by pipe crossbeam 1, and the end shrouding 4 of overlapping department is equipped with a hole, and end shrouding 4 and pipe crossbeam 1 are fixed through the bolt that passes a hole, but the bolt horizontal migration makes pipe crossbeam 1 scalable in a hole, and when the change of temperature aroused that the bridge floor structure's expend with heat and contract with cold too big or when harm such as earthquake, pipe crossbeam 1 can be flexible in end shrouding 4 departments, plays the effect of buffering displacement.

As an improvement of the technical solution, as shown in fig. 4, in order to make the circular tube beam 1 extend and contract and the steel base 3 also extend and contract at the same time, a square sleeve 5 is arranged at the expansion joint of the bridge on the steel base 3, two ends of the square sleeve 5 are sleeved by the steel base 3, one end of the square sleeve 5 is welded with the steel base 3, and the other end is not welded.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
