Description

Bridge waterproof coating structure

Technical Field

The application relates to the technical field of bridge waterproofing, and particularly discloses a bridge waterproof coating structure.

Background

At present, in the waterproof layer adopted by some highway bridges, cracks often appear for a long time in the use process, so that water permeates through the cracks to influence the waterproof effect; the reason is that most of materials are composed of a non-woven fabric layer, a woven fabric layer and an asphalt surface, and after long-term sunshine exposure, the non-woven fabric layer and the woven fabric layer are sun-cracked to cause that asphalt is also exposed to the sunshine and is finally sun-cracked to cause sudden drop of a waterproof effect, so that a new technology or structure is needed in the market to make up for the defect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the poor problem of traditional bridge water proof coating structure water-proof effects.

In order to achieve the above object, the present invention provides the following basic scheme:

the utility model provides a bridge waterproof coating structure, includes the base member layer with the bridge contact, the top on base member layer is equipped with the rigidity waterproof layer, the rigid coupling has a plurality of stiffeners between rigidity waterproof layer and the base member layer, the top of rigidity waterproof layer is equipped with first thin layer, pitch layer, second thin layer, glue layer and rubber layer in proper order.

The principle and effect of this basic scheme lie in:

1. compared with the prior art, this device sets up the base member layer, and the concrete can be chooseed for use on the base member layer, inserts the stiffener and is used for fixed rigidity waterproof layer for the waterproof effect is guaranteed as last protective screen to the rigidity waterproof layer.

2. Compared with the prior art, this device possesses the waterproof efficiency of two layers, and the second floor is first thin layer and second thin layer, utilizes the pitch layer as the transition layer, even the pitch layer fracture, the entering of rivers still can be blockked to first thin layer.

3. Compared with the prior art, this device has set up the glue layer, utilizes the glue layer, and fixed second thin layer and rubber layer position relation for the change of position can not take place for the second thin layer, makes the water-proof effects on second thin layer more stable, and life is longer.

Compared with the prior art, the device is provided with the rubber layer, so that the elasticity and low-temperature flexibility of rubber are kept; the anti-shearing force is strong, can withstand the requirement of long-term load and compression resistance of the bridge deck, can prevent the structural damage caused by water seepage and delay the service life of the highway bridge. It is an ideal waterproof material for bridge deck, and may be used in roof, underground, tunnel, cave and other engineering for preventing water, seepage, corrosion and water and moisture. The waterproof material not only has good waterproof performance, but also can absorb the stress and noise of road and bridge surface layers and is used as a stress absorbing layer; because of certain elastic and plastic deformation capacity, the bearing can bear load without being damaged. The ageing of road and bridge surface course is alleviated, and the service life is delayed.

Further, the first thin film layer and the second thin film layer are both waterproof thin films. The waterproof film is used for waterproofing the first film layer and the second film layer so as to improve the waterproofing effect of the first film layer and the second film layer.

Further, the surfaces of the first film layer and the second film layer are coated with sun-proof paint. The sun-proof coating can prolong the service life of the first film layer and the second film layer and prevent cracking.

Further, the thermal reflectivity of the sun-blocking paint is more than 75%. The thermal reflectivity of more than 75 percent is used as the hardness index of the sun-proof paint, and the service life of the sun-proof paint can be ensured by ensuring the thermal reflectivity of the sun-proof paint.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Reference numerals in the drawings of the specification include: rubber layer 1, glue layer 2, second thin layer 3, pitch layer 4, first thin layer 5, rigid waterproof layer 6, base member layer 7, reinforcing rod 8.

The embodiment example is shown in figure 1:

a bridge waterproof coating structure comprises a substrate layer 7 which is in contact with a bridge, a rigid waterproof layer 6 is arranged above the substrate layer to ensure the effect of hard waterproof, the rigid waterproof layer 6 is used as a hard waterproof layer, the thickness of the rigid waterproof layer 6 needs to be ensured, a plurality of reinforcing rods 8 are fixedly connected between the rigid waterproof layer 6 and the substrate layer 7, the reinforcing rods 8 are made of steel bar materials, formed by binding, specifically: in the design of the reinforcing rod 8, the base layer 7 is inserted by drilling, the insertion depth depends on the material of the base layer 7, when base member layer 7 is the concrete, the depth of insertion should not exceed the one-third of 8 overall length of excellent stiffeners, avoids the excellent overlength rupture of stiffener, and the top of rigid waterproof layer 6 is equipped with first thin layer 5, pitch layer 4, second thin layer 3, glue layer 2 and rubber layer 1 in proper order, and first thin layer 5 and second thin layer 3 all adopt waterproof film.
