STRUCTURE FOR INSTALLING SHOCK ABSORBING BOLLARD BETWEEN ROADWAY AND SIDEWALK FOR PREVENTING VEHICLE FROM MOVING INTO SIDEWALK

摘要

PURPOSE: A structure for mounting a shock absorbing system between a roadway and a sidewalk of a road is provided to offset impact of the bollard with the spring, and to prevent breakage of the bollard by dividing the bollard into the upper cover and the lower column and connecting the upper cover and the lower column with the middle connecting bar and the spring. CONSTITUTION: A lower column(310) and an upper cover(330) of a bollard(300) are connected by a middle connecting bar(320) and a spring(350), and the lower column of the bollard is composed of an insertion hole(312) of the middle connecting bar and assembling bolts(311) fixing the middle connecting bar. The lower part of the lower column is fastened by pouring concrete(200), and the middle connecting bar is composed of an assembling disk(325) combined with the lower column, a circular rod(321) inserted to the lower column, a spherical rod(322) formed in the upper part of the assembling disk and spring assembling links(323) around the assembling disk. The upper cover is composed of a shock absorbing rubber(332) and a semicircular groove(333) combined with an upper cover assembling plate(340). The spring is combined with the assembling links of the middle connecting bar and the upper cover assembling plate.
