Description

Inner locking type rubber and plastic waterstop

The utility model relates to a kind of rubber or plastics waterstop that is used for concrete structure sediment seam or shrinkage joint, particularly a kind of inner locking type rubber and plastic waterstop.

In underground construction, Foundation Design or relate on other large-scale concrete components, must consider deformation joint is set, settlement joint or shrinkage joint, so that in process of expansion and contraction, be unlikely the damage concrete main body, other avoids water to be penetrated into below the concrete foundation by settlement joint or shrinkage joint, loosening ground, to use waterstop at settlement joint or place, shrinkage joint, this waterstop requires to have waterproof, have well fixing with the cement face, the characteristic that has retractility and can use for a long time, existing waterstop has a center raised line 1 in the middle, it in raised line a hollow center pipe 2, realize the retractility of waterstop by the horizontal compressible and tensile properties of pipe, be provided with many raised lines 3 in the waterstop both side surface, in order to have well fixing with cement concrete, but this fixing means can not make the people satisfied, for this reason, people are fixing in the waterstop both sides again, and also each stretches a block plate to the outer, perforation and band together on steel plate by the aluminium in iron wire and the concrete, it is well fixing in the hope of waterstop and cement concrete are had, but can increase considerably cost like this, and steel plate is too thin not to have any effect, the too thick then production process of steel plate complexity, the transportation difficulty, it is also very inconvenient to construct.

In view of this, how to provide a kind of waterstop, it is simple that it has overall structure, with low cost, and superior performance is easy to use, utilizes architectural feature, can make waterstop and cement coagulate soil and well fix, and the utility model grinds wound motivation place just.

The utility model designer, does a brand-new design and constitutes on the basis of feasibility study repeatedly by means of being engaged in the practical experience that all kinds of rubber and plastic products are researched and produced processing and other fields for many years, gets generation of the present utility model eventually.

At the deficiencies in the prior art, the purpose of this utility model is a kind of inner locking type rubber and plastic waterstop of design, adopts rational structure, realizes that waterstop and cement concrete are well fixing.

The purpose of this utility model can be by following realization, and the utility model has a center raised line in the middle, is a central hollow pipe in raised line, it is characterized in that also being provided with in both sides 1 or many drain casting tubular structures.

The utility model is further characterized in that the cross section of drain casting pipe can be circle or random geometry; Both sides drain casting pipe can be to be symmetrical arranged; The both sides, surface are provided with one or more raised line; The drain casting pipe can be arranged in the raised line; The surface of drain casting pipe also can be provided with the hole; The hole can be in the upper and lower settings of drain casting pipe; The shape in hole can be circle or random geometry; Can be provided with steel pipe or steel spring in Grouting Pipe, dual-side is along being provided with installing hole.

The utility model advantage is rational in infrastructure, can have well fixing with concrete.

Further illustrate the utility model embodiment below in conjunction with accompanying drawing.

Fig. 1 is the prior art structure chart.

Fig. 2 is the utility model schematic diagram.

Fig. 3 is the utility model cross-sectional view.

1...... raised line 2...... center, center pipe

3...... raised line

10...... raised line 11...... center, center pipe

12...... raised line 13...... Grouting Pipe

14...... hole 15...... installing hole

The utility model has a center raised line 10 in the middle, the center raised line can be the plane, to guarantee the construction formwork positioning stablity, it in center raised line 10 a central hollow pipe 11, also be provided with 1 or many drain casting pipe 13 structures in both sides, can inject cement concrete in this Grouting Pipe 13 (also claiming grout pipe), muscle in forming, reach with concrete inside and outside unify, be securely fixed in the concrete.

The further characteristics of the utility model are that the cross section of drain casting pipe 13 can be circle or random geometry; Both sides drain casting pipe can be to be symmetrical arranged, and also can be non-being symmetrical arranged; The both sides, surface are provided with one or more raised line 12, and the thickness of each raised line 12 can be identical or inequality, and both sides can be symmetries or asymmetric; Drain casting pipe 12 can be arranged in the raised line 12; The surface of drain casting pipe 13 also can be provided with hole 14, also can conveniently inject cement concrete from these holes 14; Hole 14 can be in the upper and lower settings of drain casting pipe 13; The shape in hole 14 can be circle or random geometry; Can be installed with steel pipe or steel spring in Grouting Pipe, to strengthen the intensity of Grouting Pipe, be beneficial to the grouting operation, the utility model dual-side is along being provided with installing hole 15, and the utility model can adopt rubber or plastic material to make.

In sum, the utility model can utilize overall structure advantages of simple design, make with low cost, superior performance, easy to use, utilize architectural feature, can make waterstop and cement coagulate soil and well fix.Obviously the utility model is the new design of a kind of novelty, progress and dark tool practicality.The above is specific embodiment of the utility model and the know-why used, if the equivalence of doing according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that manual and accompanying drawing contain yet, all should be in scope of the present utility model, explanation hereby.
