D40型桥梁伸缩缝@多少钱一米///
D40型伸缩缝由一条整长的橡胶密封条，一组钢质边梁及锚固件组成。钢质边梁外侧的锚固件，与梁端预埋钢筋相焊接，浇筑高强度混凝土过渡段后，同梁体连结。 D40型伸缩缝具有连结可靠，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。适用于伸缩量为 40mm,60mm 和 80mm 的桥梁。
D40 type expansion joint consists of a whole length rubber sealing strip, a group of steel side beams and anchor components. The anchor on the outside of the steel edge beam is welded with the embedded steel bar at the end of the beam, and then the beam is connected with the beam body after pouring the transition section of the high-strength concrete. The D40 type expansion joint has the characteristics of reliable connection, smooth connection with the bridge deck, sealing and sealing, flexible expansion, stable running and long service life. Applicable to the expansion capacity of 40mm, 60mm and 80mm bridge.
主要材料
Main material
钢质边梁：采用16Mn 钢轧制，剖面呈F形。
Steel edge beam: the 16Mn steel rolling section is in the shape of F.
密封胶条：采用氯丁或三元乙丙橡胶制造，具有良好的耐老化、耐曲挠性能。
Sealing strip: made of neoprene or three yuan ethylene propylene rubber, has good aging resistance, bending resistance performance.
锚固件：有锚钉、锚环、锚板结构三种，桥梁工程师可根据桥面板设计厚度选用，本公司也可特殊设计制造。
Anchor: there are anchor, anchor ring, anchor plate structure of three kinds, bridge engineers can be selected according to the thickness of the bridge deck design, the company can also be specially designed and manufactured.
D40型伸缩缝是适用于设计荷载为汽超 20 挂超120 级的直桥、弯桥、斜桥、坡桥等公路和城市桥梁。 由于它采用钢质边梁、鸟形橡胶密封条和锚固构件组成。在桥梁梁体因温差等因素引起位移时，机械固定在边梁沟槽中的橡胶密封条能自由折迭伸缩。起到防水防尘作用。行驶车辆的冲击力，通过边梁和焊接的锚固构件传递到桥梁结构中。该型伸缩缝适用于伸缩量 0～80mm 的桥梁。
D40 type expansion joint is applicable to the design of steam load for the super 20 super 120 hang straight bridge, the curved bridge, skew bridge and ramp bridge, highway and city bridge. Because it is made of steel side beam, bird shaped rubber sealing strip and anchor component. In the bridge body due to the temperature difference caused by mechanical displacement, fixed to the side beam groove in rubber seal can free telescopic folding. Play the role of waterproof and dustproof. The impact force of the moving vehicle is transferred to the bridge structure through the side beam and the welded anchorage member. The bridge is suitable for the expansion of 0 ~ 80mm type expansion joint.
1、GQF-D 型桥梁伸缩缝整条采用氯丁或三元乙丙橡胶制作，具有良好的耐老化、耐曲挠性能。适应桥梁梁端 水平、横向、竖向变形，伸缩阻力极小。
1, GQF-D type bridge expansion joint is made of neoprene or three yuan ethylene propylene rubber, and has good aging resistance, bending resistance performance. To adapt to the bridge beam end horizontal and lateral and vertical deformation, stretching resistance is minimal.
2、钢质边梁采用 16Mn 精轧而成，锚固板及Φ16锚固筋具有良好的机械性能。作用于边梁上的车辆冲击力，通过锚固构件均衡的传递到梁体上，有很长的使用寿命。
2. The steel side beam is finished by 16Mn finishing, and the anchoring plate and the 16 anchor bar have good mechanical properties. The vehicle impact force acting on the side beam is balanced to the beam body by the anchor component and has a long service life.
