结构特点与功能:
Structural features and functions:
GQF-C型伸缩缝由一条整长的橡胶密封条，一组刚质边梁及锚固件组成。钢质边梁内侧带有能固定橡胶密封条的沟槽。焊固在钢梁外侧的锚固件，与梁端预埋钢筋相焊接，浇筑高强度混凝土过渡后，同梁体连接可靠，具有与桥面接合平顺，密封止水、伸缩灵活，行车平稳，使用寿命长的特点。使用于伸缩量0～80mm的桥梁。
The GQF-C expansion joint consists of a long rubber seal, a group of rigid side beams and anchors. A groove on the inside of a steel side beam has a groove that can be fixed with a rubber seal. The anchorage piece fixed on the outer side of the steel beam is welded with the embedded steel bar at the beam end. After pouring the high strength concrete, it has reliable connection with the beam body. It has the characteristics of smooth connection with the bridge deck, sealing and water stopping, flexible expansion, stable driving and long service life. The bridge is used for the expansion of 0 to 80mm.
主要材料：
Main materials:
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 seal: made of chloroprene rubber, it has good aging resistance and torsion 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 anchors: there are three kinds of anchor bolts, anchor rings and anchor plates. The design engineers can choose the thickness according to the design thickness of the bridge deck. The spacing is generally 20cm, and the factory can also be designed and manufactured according to the design engineer.
选定伸缩缝规格尺寸:
The size of the expansion joint is selected:
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 of the selected expansion joint has a great relationship with the service life. Enough expansion allowance should be taken into account in 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*，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
β=45゜ ∽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△Lr=73mm,△Lp=61mm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 Lr=73mm, Delta Lp=61mm 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**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, we should pay attention to the rubber strip in the middle part. The horizontal error in the two directions should not exceed 40mm. If there is excess dislocation in the calculation, we must use larger size expansion joint.
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。
When designing, for example, a sidewalk and anti-collision wall structure, we must provide the design angle and dimension data to our factory, which is convenient for the factory to manufacture according to the design requirements.
