Abstract
The invention discloses a bolt-connection-free assembled bridge guardrail. The bolt-connection-free assembled bridge guardrail comprises fixed bases and hollow pipe stand columns which are sequentially arranged at intervals, and transversely-arranged connecting rods are arranged between the hollow pipe stand columns; a connecting pipe extending to the interior of the corresponding hollow pipe stand column is vertically arranged on each fixed base, and through holes are formed in the lower portions of the two sides of each hollow pipe stand column; guide holes corresponding to the through holes and limiting rods arranged in the guide holes are arranged on the side faces of the connecting pipes, and the outer portions of the limiting rods are sleeved with springs; and downward slope surfaces are arranged at the tail ends of the limiting rods. Through the manner, by means of the bolt-connection-free assembled bridge guardrail, the slope surfaces are utilized for pushing the limiting rods to the interiors of the connecting pipes, and after the hollow pipe stand columns descend to the bottoms, the through holes are communicated with the guide holes to enable the limiting rods to be pulled into the through holes under the effect of the springs; displacement of the hollow pipe stand columns is limited, and the bridge guardrail is rapid in construction, firm in structure, attractive in appearance and convenient to maintain.

Guardrail on bridge mostly is welded, also will polish and spray paint after welding, and speed of application is slow, and cost is high, and is difficult to safeguard and change, and needs to cut, improve the cost of maintenance when replacing.In order to reduce difficulty of construction, part guardrail have employed bolt and connects, but the bolt of One's name is legion reduces installation effectiveness, and screw bolt and nut is all outside exposed, affects the aesthetic measure of guardrail, and bolt gets rusty easily and is difficult to safeguard.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one and exempts from bolted assembling Bridge guardrail, quick for installation, easy to maintenance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide one to exempt from bolted assembling Bridge guardrail, comprise: spaced firm banking and hollow section column successively, described hollow section column is vertically arranged on the top of firm banking respectively, horizontal connecting rod is provided with between described hollow section column, described firm banking is vertically provided with the tube connector that a section extends to hollow section column inside, the bottom of described hollow section column both sides is provided with through hole, the gag lever post that described tube connector side is provided with the pilot hole corresponding with through hole and is arranged in pilot hole, described gag lever post outer cover is provided with spring, described both ends of the spring is connected with gag lever post top with tube connector inwall respectively and gag lever post is drawn in through hole, the end of described gag lever post is provided with downward domatic.
In a preferred embodiment of the present invention, described hollow section column top is provided with a waterproof cover.
In a preferred embodiment of the present invention, described horizontal connecting rod runs through hollow section column successively, and described hollow section column is provided with the through hole corresponding with horizontal connecting rod.
In a preferred embodiment of the present invention, the inwall of described hollow section column is corresponding with the outer wall of tube connector.
In a preferred embodiment of the present invention, outside described through hole, be respectively arranged with the protective cover extended in through hole.
In a preferred embodiment of the present invention, be provided with T-shaped locating piece below described firm banking, described T-shaped locating piece, firm banking and tube connector are integrated.
The invention has the beneficial effects as follows: the one that the present invention points out exempts from bolted assembling Bridge guardrail, utilize horizontal connecting rod that hollow section column is together in series, then when hollow section column is enclosed within tube connector outside downwards, utilizes domatic and gag lever post is pushed to tube connector inside, after hollow section column drops to bottom, through hole and pilot hole are connected and make gag lever post draw in through hole under the action of the spring, limit the displacement of hollow section column, quick construction, sound construction, exterior appearance, easy to maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is a kind of structural representation of exempting from the preferred embodiment of bolted assembling Bridge guardrail one of the present invention;
Fig. 2 is the part A enlarged drawing in Fig. 1.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
One exempts from bolted assembling Bridge guardrail, comprising: spaced firm banking 1 and hollow section column 2 successively, and described hollow section column 2 is vertically arranged on the top of firm banking 1 respectively, is provided with horizontal connecting rod 3 between described hollow section column 2.Utilize horizontal connecting rod 3 hollow section column 2 successively spaced series, described hollow section column 2 is provided with the through hole corresponding with horizontal connecting rod 3, described horizontal connecting rod 3 runs through hollow section column 2 successively, during practical operation, middle hollow section column 2 is run through, through hole on head and the tail two hollow section columns 2 only gets through the side of hollow section column 2, and opposite side is closed, good to the stationarity of horizontal connecting rod 3.
Described firm banking 1 is vertically provided with the tube connector 12 that a section extends to hollow section column 2 inside, the bottom of described hollow section column 2 both sides is provided with through hole 21, described tube connector 12 side is provided with the pilot hole corresponding with through hole 21 and is arranged on the gag lever post 5 in pilot hole, described gag lever post 5 outer cover is provided with spring 6, described spring 6 two ends are connected with gag lever post 5 top with tube connector 12 inwall respectively and gag lever post 5 are drawn in through hole 21, and the end of described gag lever post 5 is provided with downward domatic.When hollow section column 2 is enclosed within tube connector 12 outside downwards; utilize the domatic of gag lever post 5 and gag lever post 5 is pushed to tube connector 12 inside; after hollow section column 2 drops to bottom; through hole 21 and pilot hole are connected and make gag lever post 5 under the effect of spring 6, draw in through hole 21; limit the displacement of hollow section column about 2; quick construction; and sound construction; outside does not have weld mark or exposed bolt; better appearance; and easy to maintenance, import steel pole in through hole 21 outer end, make gag lever post 5 retraction pilot hole can extract hollow section column 2.
