單組式伸縮縫主要材料：鋼質(zhì)邊梁：采用16Mn的鋼軋制，部面呈c形。橡膠密封條：采用氯丁橡膠制造，具有良好的耐老化、耐撓性能。
A single group type expansion joint material: steel edge beam with steel rolling 16Mn, the Ministry is C. Rubber sealing strip: made of chloroprene rubber, it has good aging resistance and torsion resistance.
固錨件：有錨栓、錨環(huán)、錨板結(jié)構(gòu)三種，設(shè)計(jì)工程師可根據(jù)橋面板設(shè)計(jì)厚度選用，間距一般為20cm，本廠也可根據(jù)設(shè)計(jì)工程師特定設(shè)計(jì)制造。
Solid anchor: there are anchor bolt, anchor ring, anchor plate structure of three kinds, the design engineer can be selected according to the thickness of the bridge deck design, spacing is generally 20cm, the factory can also be designed and manufactured according to the specific design engineer.
選定伸縮縫規(guī)格尺寸選定伸縮縫的規(guī)格尺寸與使用壽命關(guān)系很大，在設(shè)計(jì)時(shí)應(yīng)考慮足夠的伸縮富余量。當(dāng)橋梁位移方向與伸縮縫中心線正交時(shí)，選用伸縮縫規(guī)格比較*，但橋梁位移方向與伸縮縫中心斜交時(shí)，須分解成平行與垂直于中心線的兩個(gè)矢量，選用伸縮縫規(guī)格取決于兩個(gè)矢量當(dāng)中的一個(gè)。與接縫平行的矢量：△Lp=△L.cosβ；與接縫垂直的矢量：△Lr=△Lr.sinβ式中：表示橋梁位移的總變形量；為位移方向與接縫方向的交角β=45゜∽135°△Lr是選用伸縮縫規(guī)格的依據(jù)，△Lp的變形一般由橡膠密封條的水平錯(cuò)動(dòng)老完成，對(duì)伸縮縫的選用無(wú)太大的影響。
It is very important to choose the expansion joint size and service life of the expansion joint specification size, and should consider enough expansion allowance in the design. When the bridge displacement direction and the center line of the orthogonal expansion joints, expansion joints selection specification is relatively easy, but the direction and displacement of bridge expansion joint center oblique, must be decomposed into parallel and perpendicular to the center line of the two vectors, the expansion joint specification depends on two vector one. With the vector parallel seam: Delta Lp= and delta L.cos beta; vector joint vertical: Delta Lr= Delta Lr.sin beta type: said the total deformation of bridge displacement; displacement direction and direction of the joint angle beta =45 to 135 DEG Lr Eve joy is the selection of expansion joint specification, the deformation is generally composed of delta Lp rubber sealing strip moving old wrong level, without too much influence on the expansion joint.
例：設(shè)計(jì)橋梁沿結(jié)構(gòu)中心線位移95mm，伸縮縫與其斜交40°，按公式計(jì)算△Lr=73mm,△Lp=61mm選用本型號(hào)的伸縮縫是適用的。同時(shí)要注意，膠條以中部為準(zhǔn)，較大水平錯(cuò)動(dòng)量在前后兩個(gè)方向都是不應(yīng)**過(guò)40mm，如計(jì)算中發(fā)現(xiàn)有過(guò)量錯(cuò)動(dòng)，須選用較大規(guī)格的伸縮縫。設(shè)計(jì)時(shí)，如帶有人行道，防撞墻結(jié)構(gòu)的，必須將設(shè)計(jì)角度，尺寸數(shù)據(jù)提供給本廠，便于工廠按設(shè)計(jì)要求整體制造。
Example: the design of bridge structure displacement along the center line of the 95mm, with its 40 degree oblique joints, calculated according to the formula of delta Lr=73mm, Delta Lp=61mm used this type of telescopic seam is applicable. At the same time, we should pay attention to the central part of the rubber strip, and the maximum horizontal dislocation should not exceed 40mm in the two directions. If the excessive movement is found in the calculation, the larger size expansion joint must be used. Design, such as with sidewalks, anti-collision wall structure, must design angle, size data provided to our factory, convenient for the factory according to the design requirements of the overall manufacturing.

• 橡膠止水帶的施工方法

  橡膠止水帶施工與安裝方法的正確性是使用橡膠止水帶的關(guān)鍵所在，我們知道橡膠止水帶是在混凝土澆注過(guò)程中部分或全部澆埋在混凝土中。由于混凝土中有許多尖角的石子和銳利的鋼筋，所以在止水帶定位和混凝土澆搗過(guò)程中，應(yīng)注意安裝定位方法和澆搗壓力，以避免止水帶被刺破。由于塑料和橡膠的抗斷撕裂強(qiáng)度比拉伸強(qiáng)度低3-5倍，所以如果產(chǎn)品被刺破將會(huì)大幅度降低產(chǎn)品抵抗外力的能力，故在施工中要格外注意。?進(jìn)行橡膠止水帶施工時(shí)具
