Abstract
The utility model relates to the base seats of upright posts for arranging anti-collision plates on both sides of a high-grade highway, particularly a selective replaceable guard-rail post base device. The utility model is characterized in that a guiding tube is fixed on the wall of the centre hole of a concrete column base; a conical compactor is fixed on the bottom of the centre hole whose upper opening is fixed with a buffer guard ring; the inner wall of the lower part of a steel tube column which is arranged in the centre hole is movable fit with a flange on the opening of the compactor, and the upper part of the steel tube column is tight fit with the rubber ring of the buffer guard ring. The utility model has the advantages that the performance of vibration absorption is good; the utility model is not easy to be damaged; the column can be disassembled, assembled, replaced and fixed conveniently; the column is not easy to be lost; the construction is convenience, fast and low cost; mechanized operation can be realized.
Description
The utility model relates to the basis seat, particularly swapping type fence post base device that the Crashworthy plate column is installed in the high-grade highway both sides.
At present, Crashworthy plate is built and the column buried underground in the high-grade highway both sides at home, generally based on piling.But in the geological conditions complexity, under the piling situation of difficult, adopt two kinds of practices usually, a kind of is that column is installed in the concrete preformed hole, uses sand and pitch packing again; Another kind is the flange that connects column by the stone bolt of concrete foundation, and column is fixed.These two kinds of practices part that all comes with some shortcomings adopts the concrete preformed hole that column is installed, with sand and pitch packing, energy-absorbing effect is not very desirable, and under the collision load effect, in a single day the concrete hole wall is extruded bad, repair very difficultly, in addition, be pulled out easily and lose; Adopt the flange of the stone bolt connection column of concrete foundation to fix column, after stone bolt damaged under column is collided load action, dismounting, replacing, vertical columns were just very difficult.
The purpose of this utility model is to provide a kind of swapping type fence post base device, in the geological conditions complexity, under the situation about can not drive piles, adopt this device shock-absorbing performance good, slight collision can not damage, in addition, steel pipe post dismounting, replacing, vertical columns are very convenient, and steel pipe post is difficult for losing.
The utility model is achieved in that a kind of swapping type fence post base device, comprise concrete column base and steel pipe post, affixed steel guide pipe on the hole wall of concrete column base centre bore, affixed the cone compactor in the bottom of concrete column base centre bore, suitable for reading affixed the buffering guard ring that rubber buffer ring is housed at concrete column base centre bore, the opening flange that is installed in the inwall of the steel pipe post bottom in the concrete column base centre bore and cone compactor top movingly, the rubber buffer ring tight fit of the top of steel pipe post and buffering guard ring.
The utility model can assemble prefabricated in factory, will cushion guard ring in factory, guide pipe, with the cone compactor with carry out concrete pouring after cage of reinforcement welds and become the concrete column base.The concrete column base is placed to behind the roadbed in the buffering guard ring, installs rubber buffer ring, steel pipe post is installed in the concrete column base centre bore, tighten the fastening bolt of cone compactor with special tool, the opening flange that makes taper compactor top to around spreading, rise the steel pipe walls of steel pipe post bottom big and the steel guide pipe is adjacent to, steel pipe post is fixed.Because the utility model rubber buffer ring that is provided with suitable for reading makes the shock-absorbing performance of this device good, slight collision can not damage.Fix steel pipe post with fastening bolt control cone compactor, therefore, dismounting, replacing, vertical columns are all very convenient.This device just can be pulled down fastening bolt with special tool, and steel pipe post is difficult for losing.
Accompanying drawing 1 is a cross-sectional schematic of the present utility model, and accompanying drawing 2 is the vertical view of compactor.Below in conjunction with accompanying drawing the utility model is further described, a kind of swapping type fence post base device, comprise concrete column base (9) and steel pipe post (1), affixed steel guide pipe (5) on the hole wall of concrete column base (9) centre bore, affixed the cone compactor in the bottom of concrete column base (9) centre bore, suitable for reading affixed the buffering guard ring (3) that rubber buffer ring (2) is housed at concrete column base (9) centre bore, uniform cage of reinforcement (4) and steel guide pipe (5) in concrete column base (9), the base of cone compactor, buffering guard ring (3) welds together, the opening flange that is installed in the inwall of steel pipe post (1) bottom in concrete column base (9) centre bore and cone compactor top movingly, rubber buffer ring (2) tight fit of the top of steel pipe post (1) and buffering guard ring (3).The cone compactor comprises cone (7) and the compactor (8) that connects with bolt (6), compactor (8) is for being symmetrical arranged opening on the conical shell that has flange, the bottom of conical shell is being provided with the disc base of tool with step, the step periphery of disc base and steel guide pipe (5) are fixed together, the cone (7) that has centre bore matches with the conical shell inwall of compactor (8), the bolt head that has the bolt (6) of shoulder block is the square bar, the screw rod of bolt (6) matches with the screw at compactor (8) center, when fastening bolt (6), the shoulder block of bolt (6) presses down cone (7) by packing ring, force the opening spreading of compactor (8) conical shell, make the opening flange rise steel pipe post (1) inwall big and steel guide pipe (5) compresses by symmetry.The utility model easy construction, speed is fast, can reduce the field construction cost greatly, uses this device can realize mechanized in grand sight mould construction operation.
