2. Description of the Related Art Forming a gap between structural parts such as a concrete part and a metal part is indispensable for the construction or maintenance of the structure, and various gap filling means have been conventionally adopted. The applicant also has a Japanese Patent Publication No. 62-1
He made proposals such as No. 5791 and Design Registration No. 727917, and was involved in its production and practical construction. Needless to say, various proposals and implementations are being made by other persons skilled in the art.

However, in the prior art as described above, under the above-mentioned technical conditions, the seal is effective and appropriate for manufacturing the sealing material and for various changing conditions of the gap between the members. It is not always easy to set and secure a stable sealing action.
That is, the shape of the gap between the members in which such a sealing material is adopted changes in various ways, and it is necessary that the cross-sectional shape of the sealing material changes in various ways in order to respond effectively to such changes in the applied portion. However, it is not easy to form such various deformed states and to secure a stable setting for the gap.

Further, it is unavoidable that the material for obtaining the preferable deformation effect as the above-mentioned sealing material is rubber, and this rubber material is capable of responding promptly to the various inter-member gaps as described above, and is stable and effective. In order to maintain a proper setting seal state, the setting seal parts on both sides have a certain area, and the setting seal parts form and secure a closed state and are freely deformable and expandable. It is necessary to ensure proper vulcanization of such members, and it is not easy to satisfy them properly.

In addition, it is not easy to form and secure an accurate seal under conditions where the internal and external pressures change or under conditions where vibrations, shocks, sound waves, etc. are generated.
There is a disadvantage that it is difficult to obtain a sealing material that effectively secures the purpose of dustproofing, soundproofing, etc., or a material that can easily and accurately perform the gap filling and loading / unloading operation.

The gap sealing material according to the item (1), wherein a supporting protrusion is formed in the vicinity of the edge of the joint seal.

(3) By changing the bending angle of the bendable portion formed in the intermediate portion of the connecting portion, the angle of inclination of the joint seal portions formed on both sides of the connecting portion with respect to the connecting portion can be varied. The gap sealing material according to any one of the above items (1) and (2), characterized in that a loading / unloading operation between the set end faces is facilitated.

[0010]

A gap seal member having an H-shaped cross section in which the joint seal portions on both sides and the widthwise intermediate portions of the joint seal portions are connected and integrated by a joint portion, and the joint seal portions have outer ends in the width direction, respectively. By bending and projecting toward, the joint seal portion is joined to the inner surface of the groove to be set and set, so that the connecting portion of the intermediate portion covers the groove and sets the groove closed. The joint seal portion jointly seals the inner surface of the groove to easily form a closed state.

By forming a bendable portion in the intermediate portion of the connecting portion, which is bent in one direction in the width direction of the joint seal portion, the bending degree of the bendable portion can be appropriately changed. The width of the groove to be applied can be appropriately changed and the groove can be effectively covered and set.

[0012] One end side of the joint seal portion on both sides is opened outward to incline and the joint seal portion on both sides of the joint portion of the intermediate portion is protruded laterally under elastic conditions such as rubber, whereby the joint seal is formed. By forming the supporting protrusions close to the end edge of the portion, the setting state in which the inner surface of the groove to be set and the locking step portion on the inner surface of the groove are appropriately locked can be formed.

By changing the bending angle of the bendable portion formed in the intermediate portion of the connecting portion, the inclination angles of the joint seal portions formed on both sides of the connecting portion relative to the connecting portion can be varied to set between the set end faces. By facilitating the loading / unloading operation with respect to, the loading / unloading setting for the setting portion such as in the groove can be made simple and appropriate.

BEST MODE FOR CARRYING OUT THE INVENTION A concrete embodiment of the present invention as described above will be described with reference to the accompanying drawings. First, in the present invention, as shown in FIG. The joint seal portions 2 and 2 that are formed by coupling and the joint seal portions 2 and 2 that are joined together by the joint portion 21 formed in the widthwise intermediate portion of the joint seal portions 2 and 2 are centered around the joint portion 21. The seal member main body 1 having an H-shaped cross section by being folded up as shown in FIG.
Is formed so that the joint seal portions 2 and 2 bend and project both end portions in the width direction of the main body portion 1 outward, respectively, and an intermediate portion between the connecting portions 21 and 21. 2 in the width direction of the joint seal portions 2 and 2.
As shown in FIG. 5, the bendable portion 11 is formed so as to be curved in one direction.

The above-described form at the time of manufacturing as shown in FIG. 1 is such that the supporting projections 1b,
1b is formed, and the outer end portions 2b, 2b of the joint seal portion 2 are formed.
In addition, it is supported by four support lines, and a stable support state is formed. That is, such a stable supporting state is a key component during the production of the one according to the present invention, which allows smooth and appropriate vulcanization after molding with a rubber material, and even a soft integrally molded rubber product. Accurate vulcanization can be performed.

The sealing material according to the present invention, which is manufactured as a product through the vulcanization process as described above, acts on the intended groove-shaped gap hole portion 6 as shown in FIGS. That is, the end faces 15 of the structure parts 5 and 5 formed of concrete or the like,
A locking step portion 16 is provided between 15 to receive the outer ends 2b and 2b of the joining seal portions 2 and 2 provided on opposite sides of the main body 1 as described above. , 2 are set in parallel with each other and set between the structural parts 5 and 5 to seal between the two parts 5 and 5.

That is, by making the joint seal portions 2 and 2 parallel (vertical), the outer ends 2b and 2b of the seal material main portion 1 are narrowed between the structure portions 5 and 5, and the joint seal is formed. The parts 2 and 2 become parallel to each other, and are accurately dropped between the end surfaces 15 and 15 of the structure parts 5 and 5, so that the outer end parts 2b and 2b are supported on the locking step part 16 and stably set, and When the end portions 2b, 2b are restrained and joined on the support step portion 16, the upper end 2a of the joint seal portion 2 is extruded outwardly and joined to the end surface 15 to form a balanced seal state.

The sealing state by the joint sealing portions 2a and 2b as described above is a stable balanced state, and under the condition that the distance between the structural portions 5 and 5 changes considerably as shown in FIGS. A well-balanced double seal relationship is also formed, and an appropriate sealed state is secured even under changing conditions of the internal and external pressures. Even if the seal is formed with a considerable width, the amount of material for forming the seal material is small.

[0019]

According to the present invention as described above, a double seal state is formed in a sufficient range with a relatively small amount of a small amount of material, and a manufacturing process in which a vulcanization process or the like is indispensable is easily and properly performed due to rubber quality. In order to provide an effective sealing material in a simple manner, and also to form a double sealing mechanism having a considerable width effectively to secure a preferable sealing state, and so on, it is industrially possible. This is a highly effective invention.
