可卸式橡膠止水帶施工安裝方法
Construction and installation method of removable rubber water stop belt
為了便于安裝可卸式止水帶，需提前安裝預埋螺栓，要提前將預埋螺栓固定在提前預埋好的加鋼板止水片的鋼板上，并澆筑預埋在混凝土內部，該部分混凝土要仔細振搗確保其密實度；變形縫的轉角部位應做成圓弧形或45°角，圓弧半徑應根據預埋螺栓的長度確定，以2個相鄰螺栓頭的距離不影響止水帶和止水帶夾板安裝為準；預埋螺栓時為了防止其被腐蝕應在螺栓上涂抹黃油或加PVC套管；止水帶的固定應根據現場螺栓實際位置采用皮帶沖打孔方法，在止水帶安裝過程中不能用力拉扯止水帶，止水帶與夾板間以及與預埋鋼板之間應填加石棉紙或軟金屬片襯墊以確保嚴密性。
In order to facilitate the installation of the detachable sealing strip, pre buried bolt installed in advance, to advance to the waterstop and plate pre buried bolt fixed in advance of embedded steel plate, and embedded in the concrete pouring, the concrete should be carefully vibrated to ensure the compactness of the corner joints; deformation should be made the circular arc or angle of 45 degrees, arc radius should be determined according to the pre buried bolt length, bolt head to 2 adjacent distance does not affect the sealing strip and sealing belt splint installation; embedded bolts in order to prevent them from corrosion in butter or bolts with PVC sleeve tube; waterstop shall according to the actual position of the bolt punched belt method in the waterstop process can not pull the waterstop, between the waterstop and splint and embedded steel plate should be filled with asbestos paper or soft sheet metal gaskets to ensure Tightness.
止水帶是一種專用于建筑工程施工縫及變形縫的防水密封材料。
Waterproof belt is a kind of waterproof and sealing material which is specially used for construction joints and deformation joints of construction projects.
一、 止水帶作用：止水帶是利用橡膠的高彈性，在各種壓力荷載下產生彈性變形,從而起到堅固密封,可以有效地防止建筑構造的漏水,滲水并起到減震緩沖作用。
First, the role of water stop: water stop belt is the use of high elasticity of rubber, elastic deformation under various pressure loads, so as to play a strong seal, can effectively prevent the leakage of building structure, seepage, and play a role in damping buffer.
二、 止水帶用在什么工程中？
Two. What are the water stopping strips used in?
在一般較大工程的建筑設計中，由于不能連續澆筑，或由于地基的變形，或由于溫度變化引起的混凝土構件熱脹冷縮等原因，需留有施工縫、沉降縫、變形縫，在這些縫外必須安裝止水帶來防止水的滲漏問題。這些縫的防滲漏問題就要采用在變形縫的部位澆鑄橡膠止水帶的辦法來解決，它即能防止地下水(或外界水)滲漏到建筑結構中，又可防止建筑內的水漏到外界。
In the architectural design of general larger projects, due to the continuous casting, or as a result of the ground deformation, or concrete caused by thermal expansion due to temperature change and contraction, to save construction joints and settlement joints, distortion seam, seam must be installed in the water brought to prevent water leakage problems. The anti leakage seam problems must be used in the deformation of the parts casting with rubber sealing way to solve, it can prevent the leakage of groundwater (or outside water) to the building structure, and can prevent water leakage to outside buildings.
止水帶廣泛用于各種類型的混凝土結構中。例如：擋水壩、蓄水池、地鐵、涵洞遂道等地下工程中。
The water stop strip is widely used in various types of concrete structures. For example: dam, reservoir, subway, culvert tunnel and underground engineering.
三、止水帶的設計與選用
Three. Design and selection of water stop belt
止水帶的選擇：應根據構筑物的重要性等級，變形縫變形量及水壓，止水帶的適用工作環境，經濟因素等條件綜合考慮確定。
The selection of water stop belt should be determined according to the importance grade of the structure, the deformation amount and water pressure of the deformation joint, the applicable working environment of the water stop belt, and the economic factors, etc..
止水帶材質的選擇可按下列規定：
The choice of the material for the water stop belt can be made according to the following regulations:
1、一般情況下多選用天然橡膠止水帶
1. In general, natural rubber waterproof belt is usually used
2、當遇有弱酸酸、堿類腐蝕介質時，宜選用氯丁橡膠止水帶
2, when there is weak acid and alkali corrosion medium, it is better to use neoprene waterproof belt
3、當遇有油類介質時宜選用丁腈橡膠止水帶
3, in case of oil medium should choose nitrile rubber waterproof belt
4、當遇有霉菌侵蝕的可能時，應考慮橡膠止水帶的防霉性，其等級應達到2級2級以上。
4, when there is the possibility of mold erosion, should consider the rubber waterproof tape mildew resistance, its grade should reach 2, 2 or more.
5、當使用溫度為：-25-60攝氏度時選用氯丁橡膠止水帶，-35-60攝氏度時選用天然橡膠止水帶，-40-60攝氏度時選用三元乙丙橡膠止水帶
5, when the use temperature is: -25-60 degrees Celsius, choose chloroprene rubber water stop, -35-60 degrees Celsius choose natural rubber water stop, -40-60 degrees Celsius choose three yuan ethylene propylene rubber waterproof belt
四、止水帶分類：
Four. Classification of water stop belt:
按原材料分：橡膠止水帶、橡塑止水帶、合成樹脂止水帶
According to the raw materials: rubber sealing tape, rubber hose, synthetic resin hose
橡膠止水帶分為：天然橡膠止水帶、合成橡膠止水帶；天然橡膠止水帶分為是三種：三元乙丙橡膠止水帶、氯丁橡膠止水帶、丁腈橡膠止水帶；合成樹脂止水帶分四種：EVA止水帶、ECB止水帶、PE止水帶、HDPE止水帶
The rubber sealing strip is divided into: natural rubber, synthetic rubber waterstop strip; natural rubber sealing belt is divided into three kinds: three EPDM rubber waterstop, chloroprene rubber, nitrile rubber waterstop strip; synthetic resin sealing belt is divided into four kinds: EVA ECB sealing strip and sealing strip and sealing strip and PE HDPE strip
