The utility model discloses transversal personally submitting vertebra form, including trunk and a plurality of flank waterstop. The utility model realizes elastic sealing of concrete structure seams through the compression deformation of a plurality of lateral wing water stop belts, and prolongs the service life of the project; the installation cost and the later maintenance cost are relatively low, and the economic benefit is good.
Description
Technical Field
The utility model belongs to the technical field of concrete structure seam is waterproof dustproof, concretely relates to concrete structure seam joint strip.
Background
Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The term concrete generally refers to cement as the cementing material and sand and stone as the aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water (which may contain additives and admixtures) according to a certain proportion and stirring, and is widely applied to civil engineering. Because the concrete has the characteristics of shrinkage and temperature stress deformation, joints are generally arranged in the construction process, the concrete is poured in batches, or a plurality of gaps are planned to be cut by a cutting machine after the concrete is poured and solidified, if the treatment is not carried out, the foundation is easy to damage after water is accumulated on the surface; if asphalt is used for sealing gaps, the sealing effect is poor after a long time, and the effect is not ideal.
Disclosure of Invention
In order to compensate for the defects of the prior art, the utility model provides a concrete structure seam sealing rubber strip, the characteristics of sealed effect reliable, construction rapidly, low cost and maintenance cost are low.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
a concrete structure seam sealing rubber strip is in a strip shape, has a spine-shaped cross section and is made of an elastic material and comprises a trunk and a plurality of lateral wing water stop belts; the top surface is provided with a U-shaped groove along the length direction; the side wing water stop belts are symmetrically distributed on two sides of the trunk along the height direction;
preferably, a water-swelling water stop strip is arranged on the side wing water stop belt;
preferably, the top surface is provided with an elastic sealing material;
preferably, the material is compound vulcanized water-swelling rubber;
preferably, a reinforcing material is arranged inside the concrete structure seam sealing rubber strip, and the reinforcing material is a glass fiber rope, a copper wire or a steel wire.
The utility model has the advantages that:
1) the utility model adopts rubber materials, and the concrete structure joint is elastically sealed by the compression deformation of a plurality of lateral wing water stop belts, thereby prolonging the service life of the project;
2) the cross section of the utility model is spine-shaped, a plurality of side wing water stop belts can be provided with water-swelling water stop strips, and the waterproof and dustproof performance is more excellent;
3) the utility model discloses installation cost and later maintenance cost are lower relatively, have good economic benefits.

Detailed Description
The present invention will be described in detail with reference to the following embodiments.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention. As shown in fig. 1, the utility model comprises a trunk 1, a plurality of side-wing water stop belts 2 and a reinforcing material 5; the reinforcing material 5 is a special glass fiber rope with the diameter of 0.5mm and is distributed at the middle lower part of the sealing rubber strip trunk 1; the material of the sealing rubber strip is composite vulcanized water-swellable rubber which is integrally cast and molded with the reinforcing material 5; the embodiment can be suitable for concrete structure seams with longer length, and the reinforcing materials distributed in the sealing rubber strip can ensure that the sealing rubber strip can resist longitudinal stretching deformation and can be arranged in an overlong way, so that the mechanical installation is convenient, and the construction progress is accelerated; wherein the reinforcing material 5 can be replaced by copper wires, steel wires or other materials with similar functions, and the equivalent replacement is also within the protection scope of the utility model;
fig. 2 is a schematic structural diagram of the second embodiment of the present invention. As shown in fig. 2, the utility model comprises a trunk 1, a plurality of side-wing water stop belts 2 and a water-swelling water stop strip 3; the material of the sealing rubber strip is integrally cast and molded by selecting compound vulcanized water-swellable rubber; the water-swelling water stop strip 3 is arranged on the lateral wing water stop belt 2; the water-swelling sealing rod 3 generates 2-3 times of swelling deformation after meeting water, fills all irregular surfaces, cavities and gaps of the joint, generates huge contact pressure at the same time, and thoroughly prevents leakage; when the joint or construction joint is displaced and the gap exceeds the elastic range of the material, the common rubber water-stopping material loses the water-stopping function, and the material can stop water through water absorption and expansion; the water-swelling rubber is used as the plugging sealing water-stopping material, so that the consumption is saved, the characteristic of elastic fatigue caused by excessive compression of common elastic materials can be eliminated, and the waterproof effect is more reliable;
fig. 3 is a schematic diagram of a third structure according to an embodiment of the present invention. As shown in fig. 3, the utility model comprises a trunk 1, a plurality of side-wing water stop belts 2 and an elastic sealing material 4; the sealing rubber strip is integrally cast and molded by using a rubber material; the top surface of the sealing rubber strip is provided with a layer of elastic sealing material 4; two side surfaces of the elastic sealing material 4 are tightly attached to the concrete structure joint through compression deformation, so that the waterproof and dustproof performance of the sealing rubber strip is enhanced; the embodiment is suitable for the ballastless track of the railway;
fig. 4 is a schematic view of the installation structure of the present invention. As shown in fig. 4, the main construction steps are: firstly, cleaning a concrete structure seam, and installing a matched concrete structure seam sealing rubber strip after meeting the requirement; the large engineering quantity is automatically installed through special mechanical equipment, and the small engineering quantity is manually installed; the concrete structure seam sealing rubber strip can be selected according to the concrete structure of the structure seam and the actual construction quality requirement.
