可卸式橡膠止水帶施工安裝方法
Construction and installation b of removable rubber water stop belt
為了便于安裝可卸式止水帶,需提前安裝預(yù)埋螺栓,要提前將預(yù)埋螺栓固定在提前預(yù)埋好的加鋼板止水片的鋼板上,并澆筑預(yù)埋在混凝土內(nèi)部,該部分混凝土要仔細(xì)振搗確保其密實(shí)度;變形縫的轉(zhuǎn)角部位應(yīng)做成圓弧形或45°角,圓弧半徑應(yīng)根據(jù)預(yù)埋螺栓的長(zhǎng)度確定,以2個(gè)相鄰螺栓頭的距離不影響止水帶和止水帶夾板安裝為準(zhǔn);預(yù)埋螺栓時(shí)為了防止其被腐蝕應(yīng)在螺栓上涂抹黃油或加PVC套管;止水帶的固定應(yīng)根據(jù)現(xiàn)場(chǎng)螺栓實(shí)際位置采用皮帶沖打孔方法,在止水帶安裝過(guò)程中不能用力拉扯止水帶,止水帶與夾板間以及與預(yù)埋鋼板之間應(yīng)填加石棉紙或軟金屬片襯墊以確保嚴(yán)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 bded steel plate, and bded in the concrete pouring, the concrete should be carefully vibrated to ensure the compactness of the corner joints; debation 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; bded bolts in order to prevent them from corrosion in butter or bolts with PVC sleeve tube; waterstop shall according to the actual b of the bolt punched belt b in the waterstop process can not pull the waterstop, between the waterstop and splint and bded steel plate should be filled with asbestos paper or soft sheet bl 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 debation 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(chǎn)生彈性變形,從而起到堅(jiān)固密封,可以有效地防止建筑構(gòu)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 debation 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(shè)計(jì)中,由于不能連續(xù)澆筑,或由于地基的變形,或由于溫度變化引起的混凝土構(gòu)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(lái)防止水的滲漏問(wèn)題。這些縫的防滲漏問(wèn)題就要采用在變形縫的部位澆鑄橡膠止水帶的辦法來(lái)解決,它即能防止地下水(或外界水)滲漏到建筑結(jié)構(gòu)中,又可防止建筑內(nèi)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 debation, or concrete caused by thermal expansion due to temperature change and contrb, 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 debation 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(lèi)型的混凝土結(jié)構(gòu)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(shè)計(jì)與選用
Three. Design and selection of water stop belt
止水帶的選擇:應(yīng)根據(jù)構(gòu)筑物的重要性等級(jí),變形縫變形量及水壓,止水帶的適用工作環(huán)境,經(jīng)濟(jì)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 debation amount and water pressure of the debation joint, the applicable working environment of the water stop belt, and the economic factors, etc..
止水帶材質(zhì)的選擇可按下列規(guī)定:
The choice of the material for the water stop belt can be made according to the following regulations:
