Abstract
The utility model discloses a kind of water permeable concrete elastic telescopic crack structures, including water permeable concrete and base；Elastic telescopic device is equipped between adjacent two water permeable concrete.Double-Y shaped elastic piece provides enough preloads and restoring force for adjacent water permeable concrete structure, enhances water permeable concrete globality and crack resistance；After wrapping up using polyolefin, become the permeable structure of auxiliary, seeps water downwards, avoid ponding.
Description
Technical field
The utility model relates to road structure technical fields, more particularly, to a kind of water permeable concrete elastic telescopic crack structure.
Background technique
Pervious concrete is also known as celluar concrete, is that one kind as made of aggregate, cement filler and water mixing is porous light
Matter concrete, it is free of fine aggregate, and it is uniform to form hole by coarse aggregate surface cladding a thin layer cement filler slurry mutually bonding
The honeycomb structure of distribution, therefore have the characteristics that ventilative, permeable and light-weight.
Pavement or park road surface are mated formation frequently with water permeable concrete block, due to the macroporous structure of water permeable concrete, for a long time
It jams on, base's soil loosens, and rain drop erosion leads to the reduction of adhesive anti-agglomeration, causes water permeable concrete easy to crack, shortens using year
Limit.The unbearable extremely low temperature of water permeable concrete, for example when temperature is subzero, the road of laying is easy to be damaged by frost, can deform or
There is slight crack.
Generally there are three types of methods for the setting of water permeable concrete dilatation joint, are pre-buried angle bar method respectively, patterning method, try in advance, setting is wanted
Ask as follows: setting dilatation joint, road surface expansion joint (E.J.) should be identical as road surface thickness.Construction joint in construction can substitute contracting and stitch, in construction
Contracting seam, expansion joint (E.J.) should all be embedded in elastic caulking material.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of reinforcement water permeable concrete blocks
Between connection, assist it is permeable, enhance the water permeable concrete elastic telescopic crack structure of crack resistance.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of water permeable concrete elastic telescopic crack structure, including water permeable concrete 1 and base 2；Adjacent two water permeable concrete
Between be equipped with elastic telescopic device.
As optimization, the elastic telescopic device is double-Y shaped elastic piece.
As optimization, the double-Y shaped elastic piece is made of spring steel plate material.
As optimization, spring is fixed in the middle part of the double-Y shaped elastic piece.
As optimization, the double-Y shaped elastic piece and spring pass through polyolefine material wrapping and encapsulating.
Compared with prior art, the utility model has the beneficial effects that double-Y shaped elastic piece provides for adjacent water permeable concrete structure
Enough preloads and restoring force enhance water permeable concrete globality and crack resistance；After wrapping up using polyolefin, become the permeable knot of auxiliary
Structure seeps water downwards, avoids ponding.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the main structure schematic diagram of the utility model.
Marked in the figure: water permeable concrete 1, base 2, double-Y shaped elastic piece 3, spring 4.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment, as shown in fig. 1, the utility model are a kind of water permeable concrete elastic telescopic crack structure, including 1 He of water permeable concrete
Base 2；Elastic telescopic device is equipped between adjacent two water permeable concrete；The elastic telescopic device is double-Y shaped elastic piece 3.
Water permeable concrete structure is under normal condition, and Y type elastic piece provides enough pretightning forces for it；When water permeable concrete structure occurs
Displacement or deformation make, and squeeze Y type elastic piece both wings, and extruded Y type elastic piece flexible deformation simultaneously generates restoring force, is used to support
The position movement of water permeable concrete or change in shape, enhance its crack resistance, water permeable concrete structural integrity is good, makes its normal use, it is ensured that
Pedestrains safety.
Embodiment 2, the double-Y shaped elastic piece 3 are made of spring steel plate material, and durability degree is good, it is ensured that stability in use.
Embodiment 4, spring 4 is fixed in the middle part of the double-Y shaped elastic piece 3, and auxiliary is subject to the support of spring 4, is promoted to phase
Pretightning force and restoring force between adjacent water permeable concrete.
Embodiment 5, the double-Y shaped elastic piece 3 and spring 4 are water-fast using polyolefin by polyolefine material wrapping and encapsulating
Property good feature, double-Y shaped elastic piece becomes auxiliary permeable structure in expanded joint structure, seeps water downwards.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
