一、中置式橡膠止水帶介紹
I. Introduction of central rubber water stop belt
中置式橡膠止水帶也是就是通常所說的中埋式橡膠止水帶，因?yàn)樾枰袢牖炷林虚g，所以叫做中置式止水帶，也叫做內(nèi)埋式止水帶，一般應(yīng)用的為橡膠材質(zhì)的，我公司還可以生產(chǎn)塑料中置式止水帶。
Intermediate type rubber sealing strip is usually said in bded rubber water stop belt, because of the need of bded in concrete, it is called a built-in water stop, also called buried waterstop, the general application of the rubber material, our company can also produce plastic intermediate type water stop.
中置式止水帶具有較好的防水功能。由于混凝土的施工縫的防水處理非常困難，特別是不均勻沉降或者是熱脹冷縮的問題都非常難以徹底解決。因此采用止水帶，特別是中置式橡膠止水帶就會有非常好的效果。原理是通過橡膠的彈性，吸收不均勻沉降或者熱脹冷縮帶來的形變。
The central water stop belt has better waterproof function. The waterproof treatment of concrete construction joints is very difficult, especially the problem of uneven settlement or thermal expansion and cold contrb is very difficult to be compleby solved. Therefore, the use of water stop belt, especially the rubber belt in the middle, will have very good effect. The principle is that the elasticity of rubber absorbs the uneven settlement or the debation caused by thermal expansion and cold contrb.
二、中置式橡膠止水帶分類及特點(diǎn)
Two. Classification and characteristics of central rubber water stop belt
中置式橡膠止水帶當(dāng)然一般是用作地下工程防水用的，止水帶分為：止水帶、遇水膨脹橡膠 1、止水帶是利用橡膠的高彈性和壓縮變形性，在各種荷載下產(chǎn)生彈性變形，從而起到緊固密封，有效地防止建筑構(gòu)件的漏水、滲水，并起到減震緩沖作用，在許多工程建筑中，土建、水土結(jié)構(gòu)之間都有一定的伸縮要求，并還有防水防震等問題，因此采用和安裝橡膠止水帶是有效解決以上種種問題的手段。主要用于混凝土現(xiàn)澆時必須設(shè)有的永久性變形縫內(nèi)，如水渠、隧道引出口、擋水壩、輸水渡槽等。 2、遇水膨脹橡膠是公司近期研制開發(fā)的一種新產(chǎn)品。本產(chǎn)品是在橡膠中加入一種親水溶脹的高分子物質(zhì)，使其既有一般橡膠制品的性能，又有遇水自行膨脹的獨(dú)特性能，是一種新型防水材料，能起到以水止水的作用，防水效果比一般橡膠更為可靠。
Intermediate type rubber sealing belt of course is generally used in underground engineering waterproofing, sealing strip is divided into: waterstop, water swellable rubber sealing strip is 1, the use of rubber and high elastic compression debation, elastic debation under various loads, so as to effectively prevent the sealing, seepage, Water Leakage building components the play, and cushioning, in many engineering construction, there are certain requirements between the bescopic construction, soil structure, and there are problems such as waterproof and shockproof, so using and installing the rubber sealing strip is effective to solve the above problems by means of. It is mainly used for permanent debation joints in concrete pouring, such as channel, tunnel outlet, dam, aqueduct and so on. 2, water swellable rubber is a new product developed by the company recently. This product is a polymer material with a hydrophilic swelling in the rubber, which not only has the general properties of rubber products, and has the unique properties of water self expansion, is a new type of waterproof material, can play a role in water sealing, waterproof effect is more reliable than the general rubber.
三、中置式橡膠止水帶施工注意事項(xiàng)
Three, central rubber waterproof belt construction matters needing attention
中埋式橡膠止水帶是在混凝土澆注過程中部分或全部澆埋在混凝土中?；炷林杏性S多尖角的石子和銳利的鋼筋頭，由于塑料和橡膠撕裂強(qiáng)度比拉伸強(qiáng)度低3-5倍，中置式橡膠止水帶一旦被刺破或撕裂時，不需很大外力裂口就會擴(kuò)大，所以在中置式橡膠止水帶定位和混凝土澆搗過程中，應(yīng)注意定位方法和澆搗壓力，以免中置式橡膠止水帶被刺破，影響止水效果。
The bded rubber water stop belt is partially or wholly buried in concrete during pouring process. There are many sharp stones and sharp head reinforced concrete, because the plastic and rubber tear strength than the tensile strength is 3-5 times lower, middle type rubber zhishuidai once punctured or torn, without a lot of external force will expand, so in the middle type rubber waterstop bing and concrete pouring process, should pay attention to b b and pouring pressure, so as to avoid the intermediate type rubber sealing strip was punctured, affecting the sealing effect.
