Description
【考案の詳細な説明】 （産業上の利用分野） 本考案はプレキャストされたコンクリート２次製品の接
合部分における水漏防止のためのパッキン材に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a packing material for preventing water leakage at a joint portion of a precast concrete secondary product.

合、間隙ができ、水漏れが発生する。(Prior Art) Conventionally, for example, a packing material in which an adhesive material is attached to a part of a belt-shaped synthetic rubber foam having a cylindrical cross section is used for a joint portion of a secondary concrete product. However, when the secondary concrete product is unequally changed due to the ground fluctuation or the like in a state where the foam is not restored after being compressed for a long time, a gap is created and water leakage occurs.

ン材１の表面粘着性により所定以外の部分にくっついて
接合部の適切な位置に固定されない場合が多い。In addition, as another type used, for example, a cylindrical band-shaped synthetic rubber foam with adhesive material adhered on both sides corresponding to each other, or on the entire circumference, is in a state of being appropriately compressed at a predetermined mounting position. When it is fixed to the concrete, the watertightness exerts an outstanding effect, and water leakage does not occur even if the secondary concrete product undergoes unequal fluctuations. However, as shown in FIG. When it is attached to the concrete joint B and is further joined to the concrete joint B (the reverse construction method is also the same), the surface adhesiveness of the packing material 1 often sticks to a portion other than a predetermined portion and is not fixed to an appropriate position of the joint.

備したパッキン材がある。In addition, the cross section is a saddle type to facilitate construction, and a hollow synthetic rubber foam with a similar saddle type space is provided with adhesive material in the lower flat part and the concave part of the upper saddle part respectively. There is packing material.

欠点がある。(Problems to be solved by the invention) This is an improvement in the point that the adhesive does not hit the joint when aligning the joint, so it is fixed at a position other than the proper position, but the synthetic rubber foam is hollow. Therefore, when the secondary concrete products are joined vertically, there is a drawback that they are easily deformed and the adhesive material shifts from a predetermined position at the stage of alignment.

ンクリート２次製品の接合部分における水漏防止を長く
確実に維持しようとするものである。According to the present invention, such a conventional defect is eliminated and the concave groove 1a is filled with the butyl rubber-based adhesive composition 2'at a filling rate of 50 to 80%. Therefore, the butyl rubber-based adhesive composition 2'is joined at the time of construction. It is convenient for construction and can be easily fixed at an appropriate predetermined position because the secondary concrete product of the other party does not directly hit and stick to a place other than the predetermined position, and the position shifts. Instead, it aims to maintain long-term, reliable prevention of water leakage at the joints of concrete secondary products.

とするパッキン材である。(Means for Solving the Problems) The present invention is a packing material for preventing water leakage at the joint portion of a reinforced concrete flume pipe or box culvert, and the compression load value of the synthetic rubber independent foam 1 is 0.4 to 3 Kgf when the compression load value is 50%. Hardness in the range of / cm 2 and the ratio of height to width
A semi-circular concave groove is provided on one side of a strip of 1: 1 to 1: 3, the butyl rubber adhesive composition 2'is filled to 50-80% of the depth of the concave groove, and the flat back surface of the strip is further filled. The packing material is characterized in that the butyl rubber-based pressure-sensitive adhesive composition 2 is adhered in a width of 50 to 80% with respect to the entire width of the portion 1b.

ど施工性に問題を生じる。The compression load value of synthetic rubber independent foam 1 is 0.4 Kgf / cm 2 (50%
If it is smaller than (compressed), it is easy to cause misalignment 3Kgf / cm 2 (50%
If it is larger than (compressed), the workability becomes so problematic that the butyl rubber-based adhesive composition 2'in the concave groove 1a and the concrete joint portion B cannot be sufficiently pressure-bonded. Further, the butyl rubber adhesive composition 2'in the concave groove 1a is 50% of the depth of the concave groove 1a.
If it is less than 80%, it will be difficult to obtain sufficient waterproofness, and if it exceeds 80%, there will be a problem in workability such that the concrete joint part B and the butyl rubber-based adhesive composition 2'may stick to each other during alignment.

Since the closed-cell foam is not hollow, the concrete joint surface and the butyl rubber-based pressure-sensitive adhesive composition 2 ′ are pressure-bonded to each other when they are sufficiently pushed in without causing displacement.

できる実用上の効果がある。(Effect of the Invention) As described above, the packing material according to the present invention can remarkably improve the workability and, at the same time, has a large watertight effect because the butyl rubber-based adhesive composition 2'is attached to the secondary concrete product. Further, the secondary concrete product and the butyl rubber-based adhesive composition, and the butyl rubber-based adhesive composition and the synthetic rubber independent foam are bonded together.
Even if the next product moves, the packing material of the present invention has a great followability to the fluctuation and does not cause a gap. or,
Since both peaks of the concave groove are elastically brought into contact with each other at two points through a butyl rubber adhesive composition 2'existing between them, a conventional cross section having a circular shape, a semicircular shape or an elliptical shape can be obtained. In contrast, there is a practical effect that the effect of preventing water leakage can be reliably maintained for a long time.
