Abstract
The utility model discloses a bridge side safe handrail for construction. The bridge side safe handrail comprises pillars, and cross rods for connecting adjacent pillars, andfurther comprises flat hollow stress reducing boxes arranged in the length direction of the cross rods; the hollow stress reducing boxesare provided with stress reducing surfaces positioned on the inner side ofa bridge and supporting surfaces positioned on the outer side of the bridge and connected with the pillars;the upper ends and the lower ends of the stress reducing surfaces are respectively connected with arc platesthrough upper fixing plates and lower fixing plates;the cross sections of the arc plates in the perpendicular direction are arc surfaces bending toward the inner side of the bridge; elastic pillars connected with the arc platesare arranged in the middle of the stress reducing surfaces; connecting rings are arranged on the upper surfaces of the upper fixing plates; an armrest is arranged in the adjacent connecting rings in a penetrating manner;the hollow stress reducing boxes adopt box bodies, so that the structure is firmer; buffering clearances are formed in the inner partsof the hollow stress reducing boxes,so that the collisionresisting effect of the handrail is good; through the arrangement of the arc plates, the buffering effect when the bridge is collidedis good, and the blocking distance and the blocking area are enlarged due to the arc shape, so that the collisionresisting effect is good; the elastic pillars can indirectly absorb the pressure so as to improve the collisionresistingperformance.
Description
Technical field
The utility model relates to building field, especially relates to a kind of bridge side safety fence for building.
Background technology
Bridge side rail generally comprises column, cross bar and handrail, existing improvement is generally to change larger heavier column and cross bar to improve fastness, but the weak effect after improving, during with Vehicular impact, lifting surface area is little, and pressure is large, impact resistant capability is bad, vehicle is still easy to thrust column and cross bar, goes out outside bridge, causes security incident, increase the burden that has increased bridge after weight simultaneously, increased and manufactured and the cost of transport; And when shock dynamics is very little, the material of column and cross bar is really up to the mark, vehicle and bridge even if slight collision still can be wounded, and its maintenance process trouble, maintenance cost is high, also wastes time and energy.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of crashworthiness good, for ease of maintenaince bridge side safety fence for building.
To achieve these goals, the utility model is by the following technical solutions: a kind of bridge side safety fence for building, comprise column and the cross bar that is connected adjacent upright posts, also comprise along cross bar length direction and be the flat-shaped hollow power of subtracting case, the described hollow power of subtracting case has and is positioned at subtracting power face and being positioned at the supporting surface being connected with column outside bridge of bridge inner side; The top and bottom of the described power of subtracting face are connected with an arc with bottom plate by upper mounted plate respectively, arc cross section is vertically to cambered surface bending in bridge, the centre that subtracts power face is provided with the elastic being connected with arc, the upper surface of upper mounted plate is provided with connecting ring, wears a handrail in adjacent connecting ring.
As preferably, fixed plate and bottom plate one side and arc welding, opposite side inserts in the hollow power of subtracting case; Described connecting ring and upper mounted plate removably connect.
As preferably, described elastic is more than 4, and is uniformly distributed between arc and the hollow power of subtracting case.
In sum, the utlity model has following advantage: the described hollow power of subtracting case is casing, and structure is more firm, its inside forms buffer gap, has strengthened the impact resistance effect of railing; Arc in the time that bridge clashes into, good buffer effect, its arc setting has increased and has stopped distance and the area stopping, crashworthiness better effects if; Elastic can absorb its pressure indirectly, strengthens crashworthiness.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of bridge side safety fence for building, comprise the column 1 being formed in casting by coagulation, adjacent upright posts 1 connects by cross bar 2, also comprise along cross bar 2 length directions and be the flat-shaped hollow power of subtracting case 3, the described hollow power of subtracting case 3 is arranged to flat-shaped, has reduced the area occupied on bridge, and this hollow power of subtracting case 3 is welded by six block plates; The described hollow power of subtracting case 3 has and is positioned at subtracting power face and being positioned at the supporting surface that bridge outside is connected with column 1 of bridge inner side, and the hollow power of subtracting case is casing, and structure is more firm, and its formation buffer gap, inside has strengthened the impact resistance effect of railing; The top and bottom of the described power of subtracting face are connected with an arc 6 with bottom plate 5 by upper mounted plate 4 respectively, arc 6 cross section is vertically to cambered surface bending in bridge, the centre that subtracts power face is provided with the elastic 7 being connected with arc 6, arc good buffer effect in the time that bridge clashes into is set, its arc setting has increased and has stopped distance and the area stopping, crashworthiness effect is better, is provided with upper mounted plate and bottom plate simultaneously and makes the connection of arc more firm; And being set, elastic 7 can indirectly absorb its pressure, strengthen crashworthiness, further, described elastic 7 is 5, and in other embodiments, described elastic 7 can also be more than 5, and be uniformly distributed between arc 6 and the hollow power of subtracting case 3, the suction area of this setting is larger, crashworthiness better effects if; The upper surface of upper mounted plate 4 is provided with connecting ring 8, in adjacent connecting ring 8, wear a handrail 9, described connecting ring 8 is generally and is welded and fixed with upper mounted plate 4, and in the present embodiment, described connecting ring 8 is made as and removably connects with upper mounted plate 4, this mode that removably connects, by a tapped inserting column is set in the bottom of connecting ring, arranges the hole that can be threaded with this inserting column on upper mounted plate, and this mode that removably connects is conveniently carried out installation and maintenance to handrail.
Preferably, fixed plate 4 and bottom plate 5 one sides and arc 6 weld, and opposite side inserts in the hollow power of subtracting case 3, and not only sound construction of this setting, is more prone to when installing simultaneously and keeping in repair.
Described column 1 and the hollow power of subtracting case 3 all water and cast from a concrete bed, and the hollow power of subtracting case 3 is positioned at base and is equipped with a fixed bar, and this arranges has strengthened the stability that the hollow power of subtracting case 3 is connected with base.
And in the time that vehicle and described bridge railing are slight shock, only can cause the recessed deformation of arc, and little to the broken ring of vehicle, reduce the maintenance cost of vehicle; And maintenance to bridge railing only need be pulled down upper mounted plate 4 and bottom plate 5, take off arc 6, its recessed portion is recovered to be loaded on by the mode such as beating, maintenance process is simple and convenient, and without replacing parts, does not affect its fastness, and the cost of maintenance is low.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
