Description
【考案の詳細な説明】 本考案は止水板に関する。[Detailed explanation of the idea] The present invention relates to a water stop plate.
従来コンクリート構造体の継目に施工されてい

にコンクリート中に埋設されているのが普通であ
つた。またこのような止水板の全部又は一部を水
膨潤性物質で構成し、止水性を向上させることも
行なわれている。 Conventionally, water stop plates installed at joints in concrete structures have generally been completely embedded in concrete, as shown in FIG. In addition, such a waterstop plate is made entirely or partially of a water-swellable substance to improve its waterstopping properties.
このような従来の止水工法は、コンクリート中

クリートの境に空隙すなわちエアポツトが発生す
るという問題点があつた。 In this conventional water stop construction method, the water stop plate is completely buried in the concrete, so it is necessary to hold or fix the water stop plate during construction, which creates voids or air pots at the boundary between the water stop plate and the concrete. There was a problem with that.
本考案の目的は、これを解消することのできる
新たな止水板を提供することである。 The purpose of the present invention is to provide a new water stop plate that can solve this problem.
本考案の止水板は、第２図にその一例が示され
るように、止水板主体１より突出するリブ２，
２′…の間に水膨潤性物質３を保持せしめ、該水
膨潤性物質保持部に主体１及び水膨潤性物質３を

る。 As an example of the water stop plate of the present invention is shown in FIG.
A water-swellable substance 3 is held between the parts 2', and holes 4, 4' passing through the main body 1 and the water-swellable substance 3 are formed in the water-swellable substance holding part. It is characterized by being installed on the surface.
本考案の止水板主体１は、合成樹脂、合成ゴム
等公知の材料でリブ２，２′…と一体に形成され、
また水膨潤性物質３としては、例えばビニル系，
アクリル系の単一重合体，もしくは共重合体，ポ
リウレタン系重合体，セルロース，デンプン又は
その変性物，架橋物等を用いることができる。 The waterstop main body 1 of the present invention is integrally formed with ribs 2, 2', etc. from a known material such as synthetic resin or synthetic rubber.
Further, as the water-swellable substance 3, for example, vinyl,
Acrylic homopolymers or copolymers, polyurethane polymers, cellulose, starch or modified or crosslinked products thereof can be used.
なかでも，好ましいものは水膨潤性ポリウレタ
ン含有可という性物質であり、特に好ましいの
は，水膨潤性ポリウレタンと天然ゴム，合成ゴ
ム，もしくは再生ゴム等の混合物からなる可とう
性物質である。 Among these, preferred are flexible materials containing water-swellable polyurethane, and particularly preferred are flexible materials comprising a mixture of water-swellable polyurethane and natural rubber, synthetic rubber, recycled rubber, or the like.
リブ２，２′…は、止水板の用途、目的に応じ
て適当な数を設ければよい。これらのリブはその
間に水膨潤性物質を保持すると共に、補助的に継
目からの水の侵入を阻止する役割を果たす。水膨
潤性物質３は継目から水が侵入すると、水との接
触により膨張して隙を埋め、それ以上の水の侵入
を阻止するのである。 An appropriate number of ribs 2, 2', etc. may be provided depending on the use and purpose of the water stop plate. These ribs retain the water-swellable material between them and additionally serve to prevent water from entering through the seams. When water enters through the seam, the water-swellable substance 3 expands upon contact with the water to fill the gap and prevent further water from entering.
水膨潤性物質保持部に設けられる孔４，４′は
コンクリートと止水板の間にエアポツトが発生し

て膨出し孔を塞ぐには時間を要するので、コンク
リートが硬化するまでに孔が完全に塞がれること
はない。水膨潤性物質による止水機能は、硬化が
完了してガスが抜けた後、発揮される。 The holes 4, 4' provided in the water-swellable substance holding portion are provided so that air pots do not occur between the concrete and the water stop plate. The size and number of holes may be determined as appropriate within a range that does not allow concrete to flow out, and the optimum water stop plate may be designed according to the purpose of construction and the construction environment. Gas generated during concrete hardening escapes through the holes 4, 4', so no air pots are generated. Note that since it takes time for the water-swellable substance to absorb water and swell to close the pores, the pores will not be completely blocked by the time the concrete hardens. The water-stopping function of the water-swellable substance is achieved after curing is completed and gas is released.
なおこの孔からの水の流入、流出は、水膨潤性
物質の存在により阻止されるので止水性に影響す
ることはない。 Note that the inflow and outflow of water from these pores is prevented by the presence of the water-swellable substance, and therefore does not affect the water-stopping property.

目部表面に設けることができる。 In order to install the water stop plate of the present invention on the surface of a concrete structure as shown in FIG. 2, first, the water stop plate 1 is attached to a suitable formwork (not shown).
Leave it in place temporarily. Next, concrete structure 5 is placed and hardened, and further concrete structure 6 is placed and hardened. Finally, when the formwork is removed from the water stop plate, it can be installed on the joint surface of the concrete structure as shown in FIG.
かかる構成からなる本考案の止水板は従来の止
水板と異なり、コンクリート構造物の表面に設置
されるので、作業性が優れている。 Unlike conventional water stop plates, the water stop plate of the present invention having such a configuration has excellent workability because it is installed on the surface of a concrete structure.

優れ、さらに上述の如くエアポツトの発生を見る
ことがない。 Furthermore, since it contains a water-swellable material and ribs, it has excellent water-stopping properties, and furthermore, as mentioned above, there is no occurrence of air pots.
