Z型桥梁伸缩缝结构特点与功能

Z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。Z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。

钢质边梁：采用16Mn钢轧制，剖面呈c形。

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。

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。

关于Z型桥梁伸缩缝产品在桥梁上安装时的步骤及注意事项：

1、当工程施工单位在安装桥梁伸缩缝时，一旦发生碰撞变形，很难修复为合格产品，所以在安装的全过程中，一定要采取措施保护，严禁任何车辆通过。

2、一定要精心操作。如果出现现场不易调整，所以对伸缩缝的成品检查一定要认真、仔细。不合格不可运至现场。

3、在桥梁伸缩缝在安装前，要与设计图和现场核对位置、尺寸无误后，再稳放入预留槽。要将桥上各接缝处缝隙一定要用聚苯乙烯泡沫板塞严，防止浇注保护带混凝土时灌入，使缝失效。同时，也不可将装置内灌进混凝土，以免更换V形象胶带时受阻。

4.、在保护带混凝土浇筑后，前7-8日一定要及时洒水养护，以利强度增长和防止裂缝出现。

GQF-Z 型伸缩缝公路桥梁专用的伸缩装置，它由一组钢质边梁及锚固件组成加一条整长的橡胶密封条组成。在伸缩装置的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。 GQF-D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。

A telescopic device for GQF-Z expansion joint highway bridge is composed of a group of steel side beams and anchors, plus a whole length of rubber sealing strip. The anchor on the outer side of the steel edge beam of the expansion device is welded with the embedded steel bar at the end of the beam, and then the high strength concrete transition section is poured and connected with the beam body. The GQF-D 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. Bridge suitable for 40mm, 60mm and 80mm expansion.

GQF-Z type expansion joint is a new type of bridge expansion device designed by domestic highway planning and Design Institute. The product is suitable for highway, urban bridge, elevated road and interchange project with large traffic volume.
GQF-Z 型伸缩缝主要材料：钢质边梁：采用 16Mn 钢轧制，剖面呈c形。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。锚固件：有锚钉、锚环、锚板结构三种，公路桥梁工程师可根据桥面板设计厚度选用。大家可以参考：C型桥梁伸缩缝的分类及产品适用范围中的详细介绍
GQF-Z type expansion joint main material: steel side beam: rolled by 16Mn steel, the section is C shape. Sealing strip: made of neoprene or three yuan ethylene propylene rubber, has good aging resistance, bending resistance performance. Anchor: there are three kinds of anchor, anchor ring, anchor plate structure, highway bridge engineer can choose according to the thickness of bridge deck design. We can refer to: C bridge expansion joint classification and product range of application in detail
GQF-Z 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。
GQF-Z 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. This type of expansion joint is suitable for bridges with 0 ~ 80mm expansion capacity.
1、GQF-Z 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-Z type bridge expansion joint is made of neoprene or three yuan ethylene propylene rubber, and has good aging resistance, bending resistance performance. Adapting to the horizontal, horizontal and vertical deformation of the bridge beam end, the minimum expansion resistance is very small.
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
