Positioned at the outside of sole connecting portion, and sole fixed part is fixedly connected on the bottom of sole connecting portion；Sole connecting portion is near foot
The cross section of the part of plate fixed part is and column cross-section identical octagonal to stretch into sole connecting portion in column bottom
Side, the cross section of the part near sole fixed part for the sole connecting portion is octagonal, can effectively prevent sole connecting portion relatively
Rotate in column, sole connecting portion is arranged on inside column bottom, and the inwall tight fit with column.
During use, sole connecting portion can be solid construction or hollow-core construction, preferably hollow-core construction, saves
Material, reduces production cost.Can be specifically following structure: sole connecting portion can be portal structures, this portal structures by
Vertically arranged left and right two vertical side walls and the lateral sidewalls composition being located at the two vertical side walls tops in left and right, lateral sidewalls
Left and right two ends are respectively correspondingly fixedly connected with the top of two vertical side walls in left and right.The left end of lateral sidewalls and left vertical side walls
The junction at top has chamfering, and the right-hand member of lateral sidewalls also has chamfering with the junction at right vertical side walls top, falls at two
The setting at angle primarily to conveniently put into the bottom inside of column by sole connecting portion.In order to be able to securely that sole is more solid
Determine portion to be connected on the installed surface of guardrail, prevent guardrail stress from rocking as much as possible, sole fixed part includes two bar shapeds in left and right
Part, wherein, left strip piece is fixedly connected with the bottom of left vertical side walls, and right strip piece is fixing with the bottom of right vertical side walls even
Connect, left strip piece and right strip piece are respectively provided with a pair the 3rd installing holes.
Left and right two vertical side walls connect edge, left and right two before being respectively provided with the front side edge of part near sole fixed part
Edge is connected after being respectively provided with the back side edge of the part near sole fixed part for the individual vertical side walls；The pair of front connection is along in opposite directions
Setting, and connect before a pair along being obliquely installed with respect to corresponding vertical side walls, connect edge after a pair and be oppositely arranged, and after a pair
Connect edge to be obliquely installed with respect to corresponding vertical side walls.Connect edge before a pair, connect edge after a pair and two vertical side walls make
The cross section of the part near sole fixed part for the sole connecting portion is octagonal.In order to be able to more firmly by the bottom of column and foot
Plate connecting portion is connected, and can also open up the 4th installing hole in two vertical side walls, and the 4th installing hole is also heavy platform hole, should
The effect in heavy platform hole is that fixing rivet (or tapping screw) is hidden in this heavy platform in the hole, makes the overall structure of guardrail more beautiful
See.
As optimization, along having the front limit edge extending downwardly, the back edge of lateral sidewalls has in the front of lateral sidewalls
The rear spacing edge extending downwardly.The setting on front limit edge and rear spacing edge primarily to preventing column stress, its bottom up
Mobile, so that column bottom and the sole connecting portion of sole frame is departed from, front limit is along the junction tool with the front edge of lateral sidewalls
There is chamfering, spacing edge and the junction of the back edge of lateral sidewalls have chamfering afterwards, and the setting of chamfering will be primarily to convenient will
Sole connecting portion puts into the bottom inside of column.In order to improve the intensity of sole frame, lateral sidewalls, left and right two vertical side walls,
Left back spacing edge, connect before a pair along, to connect edge and the left and right strip piece as sole fixed part after a pair be aluminium alloy compression casting
It is integrally formed.
The use principle being connected with the column of sole frame and column cross rod connector is:
First sole fixed part is placed on the installed surface of guardrail, is then fixed through sole by rivet or tapping screw
The 3rd installing hole in portion, sole fixed part is arranged on the installed surface of guardrail, then again sole connecting portion is inserted column
The inwall tight fit of bottom inside, sole connecting portion and column, then make the sole frame installing hole on column vertical with left and right two
The 4th installing hole alignment on the wall of side, insertion rivet carries out assisting rivet clasp (or being fixed using tapping screw).During use
First column can be fixed together with sole frame according to practical situation, then again sole frame is fixed on guardrail installed surface；
By the column cross rod connector installing hole on the wall of projection alignment post side, make the heel post at column cross rod connector installing hole
Wall embeds by the draw-in groove being formed between projection, contiguous block and the first tubular body blind end three, then the connection of Rotary cloumn cross bar
Part, makes projection be stuck in the edge of column two minor faces of cross rod connector installing hole, then by the rivet through the first installing hole
Carry out assisting rivet clasp, in addition, the end of cross bar is inserted in the first tubulose body from the first tubular body opening, or cross bar is enclosed within first
Outside tubular body opening, the end of preferably cross bar is inserted in the first tubulose body from the first tubular body opening, then adopts certainly again
Attack screw fixtation；By column handrail connector, handrail is fixed on the top of column.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although with reference to relatively
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, the objective without deviating from technical solution of the present invention and scope, and it all should be covered at this
The right of invention will be in book.
