Abstract
The utility model discloses a non-destructive heightening concrete wall-type guardrail, which comprises a guardrail body and adds a guardrail heightening layer fixed on the original guardrail body. The non-destructive heightening concrete wall-type guardrail provided by the utility model adds the guardrail heightening layer which is fixed on the original guardrail. Without damaging the internal structure of the original guardrail as well as the pipes and cables laid inside, the guardrail can meet the standard requirements. The utility model with simple structure can greatly increase the construction efficiency, ensure the geometrical size of the appearance of the guardrail, well guarantee the intensity of the heightening part and extend the service life of the guardrail.
Description
Technical field
The utility model relates to a kind of no breakage and increases the concrete wall fence, belongs to bridge, road surface protective equipment.
Background technology
The speedway wall fence is a kind of vertical endergonic structure that is provided with in order to guarantee traffic safety on the highway, absorb collision energy by climbing from body deformability or vehicle, thereby change vehicle heading, the prevention vehicle runs off outside the road or enters the subtend track, reduce a kind of ancillary works to occupant injury to greatest extent, the main material of wall fence is reinforcing bar and concrete.Along with the develop rapidly of China's communication, the speed of a motor vehicle, carrying capacity all increases substantially than before, on some mountain roads or backroad, owing to the too low accident that causes vehicle to go out guardrail and vehicle roll of old guardrail height is of common occurrence; The early stage speedway of building of China, all enter the overhaul stage successively, because the factors such as guardrail relative altitude reduction that road covering causes all cause very big potential safety hazard to current at a high speed vehicle, above-mentioned reason causes the speedway wall fence can not satisfy the design specifications requirement of regulation, and driving is had very big potential safety hazard.
Wall fence belongs to reinforced concrete structure, the way of increasing at present is that the concrete on the original old guardrail is thoroughly cut, after exposing old guardrail reinforcing bar, welded reinforcement props up template then again, carries out cast-in-place at last again, so not only waste time and energy, original structure is caused very big damage, and when cutting, be easy to destroy and be fixed on the pipeline of passing a bridge on the wall fence, optical cable etc., thereby cause some unnecessary loss.
The utility model content
The purpose of this utility model is to provide a kind of can improve efficiency of construction, make guardrail reach code requirement, and the concrete wall fence is increased in the no breakage that does not destroy original guardrail.
To achieve these goals, the technical solution of the utility model has adopted and has fixedly had additional guardrail add high level on original guardrail body.
Described guardrail adds the reinforced concrete floor that is provided with on high-rise steel plate by the bottom surface setting, the steel plate and forms, and stiffener and steel plate in the reinforced concrete floor weld together.
Described stiffener is made up of vertical fastening reinforcing bar on stirrup and the stirrup.
Described guardrail adds high-rise and original guardrail bonds together.
Described guardrail adds high-rise and original guardrail anchor knot together.
Described guardrail adds high-rise and original guardrail bonds together, and by squeezing into crab-bolt the steel plate anchor that guardrail adds on the high level is tied on original guardrail.
The described crab-bolt of squeezing into also can be bar planting.
It is fixedly to have set up guardrail to add high level on the basis of original guardrail that the concrete wall fence is increased in nothing breakage of the present utility model, under the situation of the pipeline that does not destroy original guardrail internal construction and laid inside thereof, optical cable etc., make guardrail satisfy the requirement of standard, the utility model is simple in structure, can improve efficiency of construction greatly, can guarantee the outward appearance physical dimension of guardrail, it is increased part intensity and has also obtained good guarantee, has prolonged the application life of guardrail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the concrete wall fence is increased in no breakage of the present utility model, on original guardrail 1, fixedly have additional guardrail and add high level, guardrail adds the reinforced concrete floor that is provided with on high-rise steel plate 3 by the bottom surface setting, the steel plate 3 and forms, stiffener in the reinforced concrete floor and steel plate 3 weld together, wherein, stiffener is made up of vertical fastening reinforcing bar 4 on stirrup 2 and the stirrup 2.
Guardrail in the present embodiment adds high-rise and original guardrail is to bond together by structure glue 5, and fixing by crab-bolt 6 anchors knot.
In addition, the guardrail in the present embodiment adds high-rise and original guardrail is only tied together by crab-bolt 6 anchors, also can only bond together.
During construction, the old concrete of top end surface on the original guardrail is chiseled out, clean up, with the method for anchor knot and/or bonding guardrail is added then and high-risely be fixed on the old guardrail, last formwork, build by the steel plate on it.
It should be noted last that: above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and do not break away from any modification or partial replacement of spirit and scope of the present utility model, replace with bar planting etc. as squeezing into crab-bolt, it all should be encompassed in the middle of the claim scope of the present utility model.
