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)計時應(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，選用伸縮縫規(guī)格比較容易，但橋梁位移方向與伸縮縫中心斜交時，須分解成平行與垂直于中心線的兩個矢量，選用伸縮縫規(guī)格取決于兩個矢量當(dāng)中的一個。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動老完成，對伸縮縫的選用無太大的影響。
例：設(shè)計橋梁沿結(jié)構(gòu)中心線位移95mm，伸縮縫與其斜交40°，按公式計算△Lr=73mm，△Lp=61mm選用本型號的伸縮縫是適用的。同時要注意，膠條以中部為準(zhǔn)，大水平錯動量在前后兩個方向都是不應(yīng)超過40mm，如計算中發(fā)現(xiàn)有過量錯動，須選用更大規(guī)格的伸縮縫。設(shè)計時，如帶有人行道，防撞墻結(jié)構(gòu)的，將設(shè)計角度，尺寸數(shù)據(jù)提供給本廠，便于工廠按設(shè)計要求整體制造。
隨著我國城市的大規(guī)模發(fā)展，城市橋梁也進(jìn)行了大規(guī)模的建設(shè)。
With the large-scale development of China's cities, urban bridges have also undergone large-scale construction.
橋梁的施工工藝以及建設(shè)質(zhì)量會直接影響到橋梁投入使用后的效果，其中橋梁的伸縮縫是一大施工難點。
The construction technology and construction quality of the bridge will directly affect the effect of the bridge after it is put into use. The expansion joint of the bridge is a major construction difficulty.
伸縮縫是橋梁構(gòu)造中的重要組成部分。
Expansion joints are an important part of bridge construction.
在氣溫變化、混凝土收縮、活載作用、橋梁墩臺的沉降及徐變等因素影響下，橋跨結(jié)構(gòu)會產(chǎn)生變形，從而使梁端產(chǎn)生位移。
Under the influence of temperature changes, concrete shrinkage, live load, settlement and creep of bridge piers, the bridge span structure will be deformed, resulting in displacement of the beam ends.
為適用這種位移并保持橋上行駛車輛的平順性，在橋面的兩端之間以及梁端與橋臺背墻之間設(shè)置橫向伸縮縫。
In order to apply this displacement and maintain the ride comfort of the vehicle on the bridge, a transverse expansion joint must be provided between the ends of the deck and between the beam end and the abutment back wall.
橋梁伸縮縫一旦損壞，就會導(dǎo)致跳車、噪音、漏水、影響行車安全及縮短橋梁使用壽命。
Once the bridge expansion joint is damaged, it will cause jumping, noise, water leakage, affecting driving safety and shortening the service life of the bridge.
而橋梁施工縫的質(zhì)量與施工過程中的質(zhì)量控制有很大的關(guān)系。
The quality of bridge construction joints has a great relationship with the quality control during construction.
