Description

Road guard prefab-form

Technical field

This utility model relates to construction engineering technical field, is specifically related to a kind of road guard prefab-form.

Background technology

In order to play the separation in positive and negative track on highway, on Intermediate Gray, typically it is provided with New Jersey's formula guardrail, so-called New Jersey's formula guardrail is just provided in the stone pier of the concrete material in the middle of the road of road junction, under New Jersey's formula guardrail entirety is presented greatly Little trapezoidal platy structure, multiple New Jerseies formula guardrail arranges multiple along the length of the centre of road, New Jersey safety barrier it Between bonded to each other, constitute highway isolation strip.For convenience of the draining to guardrail, the bottom of neighbouring guardrail is provided with spilled water hole, As during New Jersey safety barrier is prefabricated, the PVC drain pipe by being plugged in prefab-form realizes osculum position Be accurately positioned, but in New Jersey's formula guardrail prefabrication process, the general vibrating compacting implemented by vibrating head concrete, Under the effect of vibrating spear, template can entirety shake, and the PVC drain pipe positioning spilled water hole can be along with the vibrations of template Produce skew, thus cause spilled water hole location positioning inaccurate.Owing to guardrail standard sections is that 4m is prefabricated at every node guard bar When, the Time Inconsistency that vibrating spear vibrates, the PVC drain pipe of spilled water hole position, location can produce the most inclined Moving the guardrail spilled water hole position disunity causing finished product, spilled water hole overall after guardrail is installed is uneven, thus can lead Cause point band draining in highway limited.

Utility model content

The purpose of this utility model is: provides a kind of road guard prefab-form, can be accurately positioned the same of spilled water hole position Time, it is guaranteed in the spilled water hole after guardrail is installed linear unanimously.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of road guard prefab-form, including the location substrate for holding in the palm support guardrail one sidewall, the plate of described location substrate Being provided with locating dowel on face, described locating dowel constitutes grafting with PVC drain pipe and coordinates, the external diameter of described locating dowel and PVC The internal diameter of drain pipe coincide.

This utility model there is also following characteristics:

A length of the 1 of described locating dowel～2cm.

Location substrate generally rectangular plate-like structure, locating dowel is positioned on the substrate of location and is provided with two, the core of two locating dowels Line is equal with the side back gauge of location substrate.

The thickness of described location substrate is 0.5～1cm.

The a length of 400cm of described location substrate, width is 123cm.

Compared with prior art, the technique effect that this utility model possesses is: guardrail is during prefabricated, prefabricated The lower section of template arranges location substrate, and the locating dowel positioning on substrate is coordinated with PVC drain pipe composition grafting, Vibrating head, during shaking concrete, positions the locating dowel on substrate, can implement firmly to determine PVC drain pipe Position, and then avoids PVC drain pipe offset, thus can be accurately positioned spilled water hole position, and then after being guaranteed in guardrail installation Spilled water hole is linear unanimously.

Detailed description of the invention

In conjunction with Fig. 1 to Fig. 4, the utility model is further described:

A kind of road guard prefab-form, including the location substrate 20 for holding in the palm support guardrail 10 1 sidewall, described location base Being provided with locating dowel 30 on the plate face of plate 20, described locating dowel 30 constitutes grafting with PVC drain pipe 11 and coordinates, described The external diameter of locating dowel 30 coincide with the internal diameter of PVC drain pipe 11.

Guardrail 10, during prefabricated, arrange location substrate 20, and makes to position substrate in the lower section of prefab-form Locating dowel 30 on 20 constitutes grafting with PVC drain pipe 11 and coordinates, and vibrating head is during shaking concrete, fixed Locating dowel 30 on the substrate 20 of position can implement the location to PVC drain pipe 11 firmly, and then avoids PVC drain pipe 11 skews, thus spilled water hole a position can be accurately positioned, and then it is linear unanimously to be guaranteed in the sluicing a after guardrail 10 is installed. The internal diameter of the drain pipe 11 of general PVC is 5cm, and therefore the external diameter of locating dowel 30 is also 5cm.

As preferred version of the present utility model, a length of the 1～2cm of described locating dowel 30.Locating dowel 30 at this Length can somewhat do shorter, constitute grafting with PVC drain pipe 11 coordinate i.e. as long as enabling to locating dowel 30 Can, after guardrail 10 completes, the locating dowel 30 of convenient location substrate 20 separates with PVC drain pipe 11, and And material can also be reduced.

As further preferred scheme of the present utility model, position substrate 20 generally rectangular plate-like structure, locating dowel 30 Being positioned on the substrate 20 of location and be provided with two, the heart yearn of two locating dowels 30 is equal with the side back gauge of location substrate 20. Typically being provided with two spilled water hole a on guardrail 10, location substrate 20 can be selected for irony material with the material of locating dowel 30 Material, it can be ensured that intensity, facilitates locating dowel 30 and welding of positioning substrate 20, and two locating dowels 30 are at location-plate 30 Fixed position equal with the distance of a side of location substrate 20, thus can ensure that the heart yearn of locating dowel 30 is in one On straight line, so guarantee two PVC drain pipe 11 linear unanimously, a side of locating dowel 30 Distance positioning substrate 20 Distance be 33cm, the distance of the dual-side of locating dowel 30 Distance positioning substrate 20 is 95cm.

Certainly, the thickness of location substrate 20 is unsuitable blocked up, and the thickness of described location substrate 20 is 0.5～1cm.

The a length of 400cm of described location substrate 20, width is 123cm.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and In the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this The scope of utility model is limited by claims rather than described above, it is intended that by the equivalent in claim that falls All changes in the implication of important document and scope are included in this utility model.Should be by any accompanying drawing mark in claim Note is considered as limiting involved claim.

Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps Containing an independent technical scheme, this narrating mode of description is only for clarity sake, and those skilled in the art should When description can also be formed art technology through appropriately combined as an entirety, the technical scheme in each embodiment Personnel may be appreciated other embodiments.
