Abstract
The utility model proposes a kind of hard isolated column for old bridge dividing strip, comprise bridge construction, described bridge construction is provided with left deck paving and right deck paving, between described left deck paving and right deck paving, be provided with isolated column; Described isolated column comprises base, and described base is fixed with guardrail; The described base left and right sides is provided with curb, arranges cement mortar bedding cushion between described curb and bridge construction.Hard isolated column for old bridge dividing strip of the present utility model adopts the corrugated guardrail of band concrete bed at median strip place, effectively can prevent errant vehicle from swarming into subtend track, cause second accident; Adopt the corrugated guardrail visual field penetrating, can effectively avoid human pilot visual fatigue.
Description
Technical field
The utility model relates to bridge building operations technical field, specifically a kind of hard isolated column for old bridge dividing strip.
Background technology
Bridge median strip place arranges guardrail, can effectively prevent errant vehicle from swarming into subtend track, causing second accident.Can directly designing dividing strip guardrail when newly building bridge, building dividing strip guardrail when building bridge simultaneously; In the old bridge not having dividing strip guardrail, also can again build dividing strip guardrail.
Existing bridge dividing strip place firmly isolates and normally arranges concrete hard shoulder, but this kind is easily caused the visual fatigue of human pilot firmly every blocking the visual field, accidents caused.
Utility model content
The utility model proposes a kind of hard isolated column for old bridge dividing strip, block the problems such as the visual field to solve prior art Bridge without hard isolation or concrete hard shoulder.
The technical solution of the utility model is achieved in that
For a hard isolated column for old bridge dividing strip, comprise bridge construction, described bridge construction is provided with left deck paving and right deck paving, between described left deck paving and right deck paving, be provided with isolated column;
Described isolated column comprises base, and described base is fixed with guardrail; The described base left and right sides is provided with curb, arranges cement mortar bedding cushion between described curb and bridge construction.
Further, described base is concrete bed, and described concrete bed is preset with fixed core, and the termination that described fixed core exposes concrete bed has external screw thread; Described guardrail is fixed on described external screw thread by nut.
Further, described fixed core is " U " shape fixed bar.
Further, described guardrail is corrugated guardrail.
Further, described curb is granite curb.
Further, described left deck paving and right deck paving all comprise concrete pavement layer and surface layer of mating formation.
The beneficial effects of the utility model are:
1, the hard isolated column for old bridge dividing strip of the present utility model adopts the corrugated guardrail of band concrete bed at median strip place, effectively can prevent errant vehicle from swarming into subtend track, cause second accident.
2, the hard isolated column for old bridge dividing strip of the present utility model adopts the corrugated guardrail visual field penetrating, can effectively avoid human pilot visual fatigue.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, 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.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the hard isolated column for old bridge dividing strip in the present embodiment, comprises bridge construction 1, and bridge construction 1 is provided with left deck paving 2 and right deck paving 3, and left deck paving 2 and right deck paving 3 all comprise concrete pavement layer 4 and surface layer 5 of mating formation; Isolated column is provided with between left deck paving 2 and right deck paving 3.
Isolated column comprises base 6, base 6 is fixed with guardrail 7.In the present embodiment, guardrail 7 is corrugated guardrail, and base 6 is concrete bed, and concrete bed is preset with fixed core 8, and in the present embodiment, fixed core 8 is " U " shape fixed bar, and the termination that fixed core 8 exposes concrete bed has external screw thread; Guardrail 7 is fixed on external screw thread by nut 9.Base 6 left and right sides is provided with curb 10, and in the present embodiment, curb 10 is granite curb; Cement mortar bedding cushion 11 is set between curb 10 and bridge construction 1.
The work progress of the present embodiment is as follows:
1, original bridge deck pavement is excised;
2, by designing requirement spread concrete pave-load layer 4;
3, cement mortar bedding cushion 11 and granite curb 10 is applied;
4, build median strip concrete bed, " U " shape fixed bar is embedded in concrete bed;
5, after concrete bed solidifies, corrugated guardrail is installed, with nut 9, corrugated guardrail is fixed on the external screw thread at " U " shape fixed bar top;
6, pave surface layer 5 of mating formation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
