Abstract
The utility model provides a water stop for a pinnate channel joint, which comprises a building water stop made of rubber material, wherein the center of the water stop is provided with a through hole, and the two sides of the through hole are respectively and symmetrically provided with a stress rib and an edge; the novel steel plate is characterized in that the thickness of the steel plate is gradually reduced from the outer diameter of the through hole to the edges of the two sides, and the edges are in a sawtooth shape from the symmetrical stress ribs to the two sides. The utility model discloses the both sides limit has the atress muscle also has the arch on the edge, makes the connection between canal body concrete and the waterstop more firm, and its is rational in infrastructure, low in production cost, and stagnant water effect, adaptation deformability are fine, and economical and practical can solve the channel prevention of seepage well, anti frost heaving problem.
Description
Technical field
The utility model relates to a kind of waterstop that uses in the agriculture as the foundation of the economy construction construction, particularly a kind of pinniform channel joint waterstop.
Background technology
In the canal engineering work progress, because distortion, sinking that ground exists, with many-sided reasons such as the humiture variation of weather, concrete shrinkage, creeps, need in channel, leave shrinkage joint or construction joint, with reduce because of concrete shrinkage be the stress that variations in temperature etc. produces; These shrinkage joint or construction joint normally adopt cement mortar or asphalt mortar, bituminous mortar or polyvinyl chloride (PVC) cement joint filling, but these joint fillers or since performance not good or since the construction inconvenience have variety of problems, and these seams are often owing to deal with improperly, and become the passage that leaks of infiltration, in case canal base water inlet, cold local, canal lining body frost heaving failure very easily takes place winter.Therefore the antiseepage of channel joint is the focus of water conservancy industry care in recent years.At present existing many technology are applied on the anti-seepage of channels, as the water seepage prevention band of making at a kind of rubber of architectural use, be used on the channel, this water band is the closed type structure, there is the twice reinforcing rib centre, when channel integrated poured, just be added between shrinkage joint or the construction joint, recharge the part cement mortar above the rubber with anti-aging, the elasticity of dependence rubber reaches the effect of antiseepage, but, because the stressing conditions of waterstop in channel is less usually, use the cost height of this waterstop, can not get in the agriculture project applying.
Technical scheme
At defective or the deficiency that above-mentioned current material exists, the purpose of this utility model is, provide a kind of materials relatively less, financial cost is lower and can play the pinniform channel joint waterstop of sealing effect.
The technical solution that realizes above-mentioned purpose is, a kind of pinniform channel joint waterstop comprises that central authorities that elastomeric material is made have a through hole and build waterstop, and the both sides of through hole are symmetrically arranged with principal rod and edge respectively; Be characterized in that the cross section of this waterstop is a thick middle, from the through hole external diameter of central authorities to the waterstop both sides attenuate gradually, the shape at edge forms zigzag fashion from principal rod to the both sides of symmetry.
Other characteristics of the present utility model are can be useful on fixing projection on the described edge.
The material of described waterstop can also be haloflex or rubber-plastics material.
Described projection can be a rectangle, also can be trapezoidal or dome-type.
Respectively to edge attenuate gradually, the edge forms pinniform from the principal rod of symmetry to both sides with waterstop because from the through hole external diameter for pinniform channel joint of the present utility model.Can satisfy the use of channel, pour in the concrete, can allow the hole surface at middle part of waterstop make the plane, flush with the channel joint section, waterstop top flushes with the both sides concrete slab like this, and one comes top need not fill out other material again, and two reduce channel roughness.
Description of drawings
Fig. 1 is the cross-section structure of structure of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Pinniform channel joint waterstop of the present utility model comprises the building waterstop that elastomeric material is made, and in the central authorities of waterstop one through hole 1 is arranged, and the both sides of through hole 1 are symmetrically arranged with principal rod 2 and edge 3 respectively; This waterstop cross section is a thick middle, from through hole 1 external diameter of central authorities to the waterstop both sides attenuate gradually, the shape at edge 3 forms zigzag fashion from the principal rod 2 of symmetry to both sides.
The shape at edge 3 can be rectangle, triangle, trapezoidal or semicircle from principal rod 2 to the both sides zigzag fashion of symmetry.
Can be useful on fixing projection 4 on the edge 3.
The material of waterstop 1 can also be haloflex or rubber-plastics material.
Described protruding 5 can be rectangle, also can be trapezoidal or dome-type.
Cast directly over concrete seam crossing in this waterstop construction, at inside concrete, the principal rod 2 of waterstop plays the effect of rib again, and the projection 4 on the jagged edge 3 of while is by having played " chock " behind the concrete coagulation, though the external diameter of through hole 1 is attenuate gradually to the edge 4 on both sides, also can not influence the intensity of waterstop, make waterstop be combined into the integral body of an antiseepage tightly with concrete; The waterstop center is an emptying aperture, and waterstop can more easily be out of shape with the canal body deformability.
Pinniform channel joint of the present utility model is saved material with waterstop, projection 4 on existing principal rod of dual-side and the edge 3, make between canal body concrete and the waterstop be connected more firm, it is rational in infrastructure, cost of production is low, stagnant water effect, to adapt to deformability fine, economical and practical, can solve the anti-seepage of channels, frost heaving resistant problem well.
