Description

Concrete road surface segmentation spacer assembly

Technical Field

The utility model relates to a road engineering technical field especially relates to a concrete road surface segmentation spacer.

Background

In order to prevent the cement road surface from expanding with heat and contracting with cold, when newly-built cement concrete road, usually can set up some horizontal expansion joints at the cement road surface, and the expansion joint can guarantee that cement concrete pavement slab is when hardening in-process and temperature reduction, unlikely because of the shrink produces irregular crack.

The cement pavement expansion joint setting mode has two kinds usually, and one kind is that the road surface is whole to be pour, then is carrying out the joint-cutting, fills the joint-cutting at last. And the other method is that the spacers are arranged on the inner side of the template during pouring, the pavement is divided into a plurality of sections at intervals, and the spacers do not need to be taken out after pouring is finished.

Most of the conventional joint cutting devices adopt a joint cutter to cut a structural joint on a pavement, and the formed cement pavement is cut to generate a large amount of dust and is lifted along with wind, so that the surrounding environment is polluted. Meanwhile, the joint cutting time needs to be strictly controlled during joint cutting construction, and the road surface can be damaged by cutting too early or too late. And adopt the mode that sets up the spacer in advance when pouring the construction, have that the construction speed is fast, the width and the quality of expansion joint advantage such as easy control.

In the prior art, battens or glass are usually used as spacers, the battens or the glass have poor self-deformation capacity, and are only used as the spacers to separate the whole cement pavement, so that the spacers cannot assist in absorbing acting force generated by expansion caused by heat and contraction caused by cold of the pavement. Meanwhile, after the wood strips or glass used as the spacers are used on the road surface for a long time, the cement road surface can crack or be damaged at the joints due to the defect phenomenon caused by long-time rolling of vehicles.

wherein the top of the return edge 221 forms a driving contact surface.

The concrete pavement segmentation spacer assembly that this application embodiment provided, the device can set up the inboard at the pouring template as the spacer when concrete pavement construction, and the length direction of bottom plate and composite sheet is all perpendicular to the formation direction and arranges. After the pouring is finished, the device can divide the whole pavement into sections, so that irregular cracks can not be generated due to shrinkage in the hardening process and the temperature reduction of the cement concrete pavement slab.

The bottom plate that this application embodiment provided can guarantee as the part of being connected with ground that the device is whole to be connected the back more stable with ground, and composite sheet one side that provides is the soft plate body of deformability, and the opposite side is the stereoplasm plate body, and soft plate body and stereoplasm plate body can adopt mode couplings such as bonding to form overall structure. The soft plate body has certain deformation capacity, so that the deformation force generated by expansion with heat and contraction with cold can be absorbed by the soft plate body in the hardening process and temperature reduction of the cement concrete pavement slab, and the aim of preventing the formed concrete pavement from cracking is fulfilled.

Simultaneously, the hard plate body that this application embodiment provided has good supporting effect, can guarantee that soft plate body can not take place deformation such as collapse, bending at the in-process of pouring.

In addition, because the top of the soft plate body that this application embodiment provided is the inflection limit parcel that this application hard plate body formed, consequently, after road surface laying is accomplished, this soft plate body can not with the vehicle direct contact of form on the road surface, but the vehicle direct contact on hard plate body and the road surface, and such mode can not appear because the vehicle rolls repeatedly and causes the destruction to the soft plate body. The anti rolling ability that the hard plate body is greater than soft material far away for the device is setting up behind the road surface, and is stronger for traditional spacers such as stuff, glass strip weatherability, can not appear because the cement road surface that the spacer damage caused splits or damages scheduling problem at seam crossing.

It can be understood that the integrated structure can be made into with the composite sheet when leaving the factory to the bottom plate that this application embodiment provided, when concrete processing preparation, can carry out fixed connection with bottom plate and stereoplasm plate body at first, then be connected soft plate body and stereoplasm plate body. When the device is used in practice, the device can be integrally carried to a position where the device needs to be placed on a selected pavement, and pouring can be carried out after the device is connected with pouring templates on two sides of the pavement. The overall length of the device can be cut on site according to the width of the road surface.

In order to enable the device to be suitable for various concrete pavements with different thicknesses and to be more convenient to transport, the base plate 1 may be provided with the insertion groove 11, and the insertion groove 11 is used for inserting the composite plate 2 to detachably connect the base plate 1 and the composite plate 2. The bottom plate that this application embodiment provided adopts the detachable mode to link to each other with the composite sheet, and such mode can make composite sheet and bottom plate form two independent structures, is favorable to packing the transportation. Meanwhile, in practical application, the base plate is firstly placed on the ground and fixed according to the installation position, then the composite plate can be cut according to the thickness of the road surface, one end, away from the return folding edge, of the composite plate can be cut according to the requirements of site construction during cutting, and the composite plate can be inserted into the insertion groove in the base plate after being cut.
