钢质边梁：采用16Mn的钢轧制，部面呈c形。橡胶密封条：采用氯丁橡胶制造，具有良好的耐老化、耐挠性能。
Steel edge beam with steel rolling 16Mn, the Ministry is C. Rubber sealing strip: made of chloroprene rubber, it has good aging resistance and scratch resistance.
固锚件：有锚栓、锚环、锚板结构三种，设计工程师可根据桥面板设计厚度选用，间距一般为20cm，本厂也可根据设计工程师特定设计制造。
Solid anchor: there are anchor, anchor ring, anchor plate structure of three kinds, the design engineer can according to the bridge panel design thickness selection, the distance is generally 20cm, the factory can also be designed according to the design engineer specific design.
选定伸缩缝规格尺寸:
Select dimensions of expansion joints:
选定伸缩缝的规格尺寸与使用寿命关系很大，在设计时应考虑足够的伸缩富余量。
The size and size of the expansion joint are closely related to the service life, and sufficient allowance should be taken into account during the design.
当桥梁位移方向与伸缩缝中心线正交时，选用伸缩缝规格比较容易，但桥梁位移方向与伸缩缝中心斜交时，须分解成平行与垂直于中心线的两个矢量，选用伸缩缝规格取决于两个矢量当中的一个。
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.
与接缝平行的矢量：△Lp△L.cosβ
With the joint vector parallel: Delta Lp Delta L.cos beta
与接缝垂直的矢量：△Lr△Lr.sinβ
With the joint vector perpendicular: Delta Lr Delta Lr.sin beta
式中：表示桥梁位移的总变形量；为位移方向与接缝方向的交角

Type: said the total deformation of bridge displacement displacement angle direction and the direction of the joint
β45゜ ∽135°
Beta 45 ~ 135 degrees Eve joy
△Lr是选用伸缩缝规格的依据， △Lp的变形一般由橡胶密封条的水平错动老完成，对伸缩缝的选用无太大的影响。
Lr is the selection of expansion joint specification, deformation Delta Lp is generally composed of rubber sealing strip the old fault level, without too much influence on the expansion joint.
例：设计桥梁沿结构中心线位移95mm，伸缩缝与其斜交40°，按公式计算△Lr73mm,△Lp61mm选用本型号的伸缩缝是适用的。
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 Lr73mm, Delta Lp61mm used this type of telescopic seam is applicable.
同时要注意，胶条以中部为准，水平错动量在前后两个方向都是不应超过40mm，如计算中发现有过量错动，须选用更大规格的伸缩缝。
At the same time, pay attention to the tape to the middle of the quasi horizontal error in the two directions are not more than 40mm, such as the calculation found excessive excessive movement, we must choose a larger size of expansion joints.
设计时，如带有人行道，防撞墙结构的，必须将设计角度，尺寸数据提供给本厂，便于工厂按设计要求整体制造。
Design, such as with sidewalks, anti-collision wall structure, we must design angle, size data available to our factory, so as to facilitate the factory according to the design requirements of the whole manufacturing.
安装前现场准备
Site preparation before installation
GQF-C型伸缩缝是在本厂制造并组装，若整条伸缩缝超长不能运输或工程需分段施工，需在现场焊接一体后，再组装橡胶密封条。
GQF-C type expansion joint is manufactured and assembled in our factory. If the whole expansion joint is too long to transport or the project needs to be constructed separately, the rubber sealing strip should be assembled after welding in the field.
（1） 伸缩缝预留槽口、在浇筑拟安装伸缩缝的梁体、桥台时，在端部预留符合安装尺寸的槽口、推荐尺寸见表1。
