PTFE slide plate

简称四氟滑板式桥梁支座，本产品是于普通板式橡胶支座上粘接一层厚2-3mm的聚四氟乙烯板而成。除具有普通板式橡胶支座的竖向刚度与弹性变形，能承受垂直荷载及适应梁端转动外，因四氟乙烯与梁底不锈钢板间的低摩擦系数（μ≤0.03）可使桥梁上部构造的水平位移不受限制，跨度>30米的大跨度桥梁、简支梁连续板桥和多跨连续梁桥可作活动支座使用；连续梁顶推、T型梁横移和大型设备滑移可作滑块使用。

Referred to as PTFE slide bridge bearings, this product is in the ordinary plate rubber bearings on a thick layer of 2-3mm PTFE plate. In addition to the vertical with normal rubber bearing stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, because of low coefficient of friction between the steel plate and beam bottom tetrafluoroethylene (U = 0.03) the horizontal displacement of the upper structure of the bridge is not restricted, span >30 meters long span bridge, continuous beam bridge and multi span continuous beam bridge can be used as a movable support; continuous beam pushing and shifting of T beam and large equipment can use the slider slip.

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 full length rubber seal, a set of rigid beams and anchors. The inner side of the steel edge beam is provided with a groove capable of fixing the rubber sealing strip. Welded on the outside of the anchor beam, and beam end embedded steel welding, casting of high strength concrete beams after the transition, with reliable connection, with the deck water sealing, smooth engagement, scalable and flexible, stable running, long service life. Used in expansion of 0 to 80mm bridge.

主要材料：

Main material:

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:

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

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.
