Description
Technical field:
The utility model relates to bridge field, particularly relates to a kind of stretching device of highway bridge guardrail.
Background technology:
In bridge construction, shrinkage joint exists as important component, and its effect is to prevent structure from producing crack because of climate change.
At present, the expanded joint structure of highway bridge guardrail mainly adopts the structure such as supporting type and dock.Supporting type structure constructs comparatively complicated construction difficulty, and greatly, cost is higher, easily distortion maintenance difficulty, and continuity is not high, vehicle through out-of-date have obviously overturn sense, there is potential safety hazard, dock structure is that the mode as filler is placed in shrinkage joint, this technique filler is easily aging, thus fracture, to come off, and then lose its due function, more not easily grasp because of the rule that bridge force-bearing is flexible, make problem more serious, be unfavorable for maintenance in the future and reparation etc.Highway bridge needs shrinkage joint adaptive temperature change is installed, but current used bridge expanssion joint, left side plate generally adopts groove to connect, elasticity is poor, weather strip generally adopts V-arrangement rubber weather strip to carry out waterproof simultaneously, the weather strip of this structure easily accumulates the foreign material such as grit, thus causes damage to weather strip, and water resistance is poor.
Utility model content:
In order to solve the problem, it is simple that the utility model provides a kind of structure, and precision high stability is good, can ensure bridge security, also has the technical scheme of waterproof effect simultaneously:
A kind of stretching device of highway bridge guardrail, mainly comprise a pair shaped steel, telescoping member, a pair shaped steel is bolted, a pair shaped steel inside upper part is equipped with engaging tooth block and groove from top to bottom, a pair shaped steel centre position is also provided with weather strip, the inside of groove inlays the two ends of telescoping member respectively, and one of them shaped steel side is provided with set bolt, and another shaped steel side is provided with telescopic hole.
As preferably, be also provided with reinforcing rib between the rear and front end of shaped steel, the quantity of reinforcing rib is N >=4, is also provided with elasticity inserts between shaped steel.
As preferably, the shape of weather strip is arch.
As preferably, also comprise caging bolt, caging bolt and telescopic hole arranged in a crossed manner, telescopic hole is long through-hole, and the quantity of set bolt is N >=5, and the quantity of telescopic hole is N >=5, and the quantity of caging bolt is N >=5.
As preferably, also comprise waterstop, the both side surface that waterstop is arranged on shaped steel is parallel with shaped steel surface.
The beneficial effects of the utility model are:
(1) the utility model adopts telescopic hole, meets the distortion needs that structure Yin Wendu produces, can ensure bridge security.
(2) the utility model arranges arch weather strip, not easily accumulates grit, increases waterstop, can play good waterproof action in shaped steel both sides.
Accompanying drawing illustrates:
Fig. 1 is Integral connection structure figure of the present utility model;
Fig. 2 is top view of the present utility model.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1-2, a kind of stretching device of highway bridge guardrail, mainly comprise a pair shaped steel 1, telescoping member 2, a pair shaped steel 1 is connected by bolt 10, a pair shaped steel 1 inside upper part is equipped with engaging tooth block 3 and groove 4 from top to bottom, a pair shaped steel 1 centre position is also provided with weather strip 31, the shape of weather strip 31 is arch, not easily accumulate grit, weather strip 31 is not easily damaged, the inside of groove 3 inlays the two ends of telescoping member 2 respectively, one of them shaped steel 1 side is provided with set bolt 5, for shaped steel 1 is fixed on bridge construction, another shaped steel 1 side is provided with telescopic hole 6, reinforcing rib 7 is also provided with between the rear and front end of shaped steel 1, the quantity of reinforcing rib 7 is N >=4, elasticity inserts 8 is also provided with between shaped steel 1, the joint of bridge will be fixed on after elasticity inserts 8 is placed in its inside, by affixed to reinforcing rib 7 and horizontal bar.
Also comprise caging bolt 9, caging bolt 9 is arranged in a crossed manner with telescopic hole 6, telescopic hole 6 is long through-hole, the quantity of set bolt 5 is N >=5, and the quantity of telescopic hole 6 is N >=5, for shaped steel 1 and adjacent shaped steel or bridge construction being linked together through telescopic hole 6 for caging bolt 9, the quantity of caging bolt 9 is N >=5, the utility model adopts telescopic hole, meets the distortion needs that structure Yin Wendu produces, can ensure bridge security.
Also comprise waterstop 11, the both side surface that waterstop 11 is arranged on shaped steel 1 is parallel with shaped steel 1 surface.The utility model increases waterstop in shaped steel both sides, can play good waterproof action.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
