Abstract

The utility model discloses an airfield pavement board reinforcing apparatus, the embedding just flushes with basic unit (5) surface basic unit (5) in, including bearing surface layer (1) at top, rubber bed course (2) and rack -layer (3) of bottom at middle part, rack -layer (3) including two horizontal support (31), and lie in a plurality of vertical supports (32) between the two. The beneficial effects are that the stress of concrete way panel end both can have been improved, and the biography lotus efficiency of slab joint department can be improved again.

Description

Airport pavement plate bracing means

Technical field

The utility model relates to a kind of airport pavement plate bracing means, is particularly useful for the seam crossing of adjacent two pieces of pavement slabs.

Background technology

In the middle of the disease of airport rigid pavement, the phenomenon of pavement slab generation purt mud and plat-bottom escape is the most general.Plat-bottom escape can accelerate the depression of pavement slab or the generation of faulting of slab ends, thus causes pavement slab to occur the problems such as fracture, and result exists potential safety hazard.Current solution to this problem injects cement paste at seam crossing to position of coming to nothing, and then butt joint place carries out the replacing of Embedding Material.Although this method can solve purt mud and plat-bottom escape phenomenon to a certain extent, can not fundamentally eliminate this disease, thus urgently improve.

Utility model content

For above-mentioned existing technical problem, the utility model provides a kind of airport pavement plate bracing means, to improve the problem of pavement slab generation purt mud and plat-bottom escape.

For achieving the above object, the utility model provides a kind of airport pavement plate bracing means, to be embedded in basic unit and to flush with substrate surface, comprising the load-bearing surface layer at top, the rubber spacer at middle part and the shelf layer of bottom; Described shelf layer comprises two horizontal supports, and is positioned at a plurality of longitudinal carriers between the two.

Further, the utility model can by successively connecting and extend, the connection of described adjacent two shelf layer, and the end being sleeved on two horizontal support docking by rubber sleeve is realized.

Further, described load-bearing surface layer uses steel or composite material to make, to strengthen weight capacity.

The utility model both can improve the stress of concrete pavement slab end, can improve again the load transfer efficiency of pavement slab seam crossing, the advantage such as simultaneously have that structure is simple, easy construction, cost are low, effective.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, the utility model to be embedded in basic unit 5 and to flush with basic unit 5 surface, comprises the shelf layer 3 of the load-bearing surface layer 1 at top, the rubber spacer 2 at middle part and bottom; Described shelf layer 3 comprises two horizontal supports 31, and is positioned at a plurality of longitudinal carriers 32 between the two.In above-described embodiment, described load-bearing surface layer 1 uses steel or composite material to make.

In the work progress of basic unit 5, the corresponding site under adjacent two pieces of pavement slab 4 plate abutted seams embeds the utility model, as shown in Figure 3, so just can strengthen the intensity of adjacent two block concrete pavement slab 4 ends.

In the various embodiments described above, in order to stress can be improved along neighboring track panel 4 seam crossing, multiple devices can be coupled together, the end of adjacent two horizontal supports 31 of docking is mainly sleeved on by rubber sleeve 33, adjacent two shelf layer 3 are connected with this, as shown in Figure 4, thus complete multiple devices docking extend.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.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.
