Abstract
The utility model relates to a sealing device of a concrete expansion joint, which belongs to the technical field of concrete water-proof device and aims to stop the water seepage of the concrete expansion joint to protect the joint of an expansion joint plate and a concrete slab. The utility model has the technical scheme that the sealing device comprises a gland sleeve and lateral plates, wherein the gland sleeve is in an inverted U shape; the top of the gland sleeve is provided with a top plate, and both sides thereof are side walls; the inverted U-shaped cavity space of the gland cover is matched with the expansion joint plate; the lateral plates are connected on the outer walls of the side walls of both sides of the gland cover; the faces of the lateral plates are vertical to the side wall of the gland cover and are parallel with the plane of the top plate; and the lateral plates are provided with a plurality of raised water-proof lines. The sealing device is arranged between adjacent concrete structures, and thereby, moisture can be prevented from permeating into the joint of the concrete slab; the lateral plates are embedded in the concrete structures of both sides, which not only takes the water-proof action but also can make the lateral plates and concrete members more tightly connected, and the water-proof lines enhance the water-proof action of the device much more. The utility model has simple structure, low cost and extremely good water-proof effect and is worthy of popularizing and applying in concrete building and road construction.
Description
Technical field
The utility model relates to a kind of device that prevents the concrete extension joint infiltration, belongs to concrete water-proof device technique field.
Background technology
In city building construction and road construction, concrete component is used more and more.For the structure that the polylith concrete connects, between adjacent concrete panels, to reserve the shrinkage joint, to adapt to the Various Seasonal variation of temperature.After but rainwater or other moisture infiltrated these shrinkage joint, long-term aggregated can damage concrete internal construction, also can cause the destruction of the expansion joint (E.J.) plate between the concrete slab simultaneously, and cause the concrete slab joint portion expansion, heave.In addition, on concrete road, a large amount of rainwater causes the face of land soft below shrinkage joint infiltration concrete slab, rolls through heavy-duty vehicle, and the rigid pavement can produce and subside, and road damages, and causes very big harm to traffic.
At present, solve two kinds of methods of the general employing of problem of concrete slab shrinkage joint infiltration, the one, the expansion joint (E.J.) plate between the concrete slab is carried out chemical treatment, make the expansion joint (E.J.) plate have water-proof function; The 2nd, at the position, shrinkage joint of concrete slab packing matcrial, cover the shrinkage joint, anti-sealing enters.Through practice, find above-mentioned two kinds of methods defectiveness still, the former adopts chemical substance treatment, and environment is polluted, and simultaneously concrete and this body structure of expansion joint (E.J.) plate is also had destruction; The latter does not protect the expansion joint (E.J.) plate, and the while inserts can not keep under external force for a long time, need constantly overhaul again, and the inserts that has also can produce reaction with reinforcing bar or concrete, causes concrete slab distortion or damage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sealing concrete extension joint device that can stop concrete extension joint infiltration, expansion joint (E.J.) plate and concrete slab joint portion are protected.
The technical scheme that solves the problems of the technologies described above is:
A kind of sealing concrete extension joint device, it is made up of sealing shroud, side plate, sealing shroud is an inverted U, and top is top board, and both sides are sidewall, the inverted U cavity space and the expansion joint (E.J.) plate of sealing shroud are complementary, side plate is connected on the outer wall of sealing shroud both sides sidewall, and the sidewall of side plate plate face and sealing shroud is perpendicular, and with sealing shroud top board plane parallel, the water-proof wire that many projectioies are arranged on the side plate, water-proof wire and sealing shroud parallel sidewalls.
Above-mentioned sealing concrete extension joint device has the resistance to compression tooth of a plurality of projectioies on the outer wall of described sealing shroud both sides sidewall, the resistance to compression tooth is arranged in parallel, and with the top board plane parallel of sealing shroud.
Above-mentioned sealing concrete extension joint device, described water-proof wire are more than 1, wherein have at least 1 to be the hydro-expansive rubber making.
Advantage of the present utility model is:
The sealing device is installed between the adjacent concrete structure; can prevent that moisture from infiltrating in the seam of concrete slab; expansion joint (E.J.) plate and concrete slab joint portion are protected; the side plate of sealing device embeds in the concrete structure of both sides; not only have waterproof action, it is tightr that sealing device is connected with concrete component, and the water-proof wire on the side plate has more been strengthened the waterproof action of this device; but the downward pressure of resistance to compression tooth enhanced leaktightness cover opposing makes sealing shroud be difficult for moving.
The utility model is simple in structure, easy to make, with low cost, waterproof effect is fabulous, is worth wideling popularize application in concrete construction and road construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Mark is as follows among the figure: sealing shroud 1, side plate 2, water-proof wire 3, resistance to compression tooth 4, expansion joint (E.J.) plate 5, concrete structure 6.
The specific embodiment
What Fig. 1 showed is structure of the present utility model, and it is made up of sealing shroud 1, side plate 2.
Also have the resistance to compression tooth 4 of a plurality of projectioies on the outer wall of sealing shroud 1 both sides sidewall, resistance to compression tooth 4 is arranged in parallel, and with the top board plane parallel of sealing shroud 1.But the downward pressure of resistance to compression tooth 4 enhanced leaktightness cover 1 opposing makes sealing shroud 1 be difficult for moving.
The utility model can adopt multiple material to make, characteristic such as that material should possess is withstand voltage, wear-resistant, corrosion-resistant, flexible, cementability is good, handling ease, price are low, and an embodiment of the present utility model adopts thermoplastic elasticity of compression rubber.Wherein water-proof wire 3 more adopts hydro-expansive rubber, to reach better waterproof effect.
What Fig. 2 showed is user mode of the present utility model.
The side plate 2 of sealing shroud 1 both sides embeds in the concrete structure 6 of both sides, play on the one hand and make sealing device be connected effect more closely with concrete component, can stop a spot of moisture that infiltrates along the slit of sealing shroud 1 on the other hand, it is deep in the concrete.Water-proof wire 3 on side plate 2 is that hydro-expansive rubber makes, run into the moisture that side plate 2 blocks after, imbibition is immediately blocked moisture fully, has stopped the infiltration of moisture, has played waterproof action.
A plurality of resistance to compression teeth 4 are arranged on the side plate 2 of sealing shroud 1 both sides, and when this device used on the rigid pavement, when over-loading vehicle tyre is pressed onto the top of sealing shroud 1, but the downward pressure of resistance to compression tooth 4 enhanced leaktightness cover 1 opposing can not move down sealing shroud 1.
The utility model in use, be enclosed within on the expansion joint (E.J.) plate 5, be placed on the position at predetermined shrinkage joint, carry out concrete pouring then, the concrete of cast and sealing shroud 1, side plate 2, water-proof wire 3, resistance to compression tooth 4, expansion joint (E.J.) plate 5 etc. closely bond, be solidified as one, concrete is pressed on sealing shroud 1 side walls, prevents that moisture from infiltrating.
