GQF—MZL型伸缩装置的突出特点是将伸缩装置的承重结构和位移控制系统分开，二者受力时互不干扰，分工明确，这样既保证受力时安全，又保证了受力时位移均匀。

The characteristic of the GQF - MZL type expansion device is separated from the expansion device of bearing structure and displacement control system, the two forces do not interfere with each other, a clear division of labor, so as to ensure the safety of the force, but also ensure the uniform stress displacement.

桥梁伸缩量计算值直接影响对伸缩装置规格选择，若伸缩装置规格选择不合理，就直接影响伸缩装置的使用效果，同时选择伸缩装置时还应考虑梁、板间伸缩装置间隙量大小，以保证伸缩装置与梁、板两端有充分锚固，才能达到*佳使用效果。所以在选择伸缩装置的规格时，一定要留足够余量，才能保证伸缩装置的使用效果和耐久性。

The value of direct influence on the choice of expansion device specification calculation of bridge expansion volume, if the expansion device specification selection is not reasonable, it directly affects the use effect of expansion device at the same time, expansion device should be taken into consideration when the beam and plate expansion device gap size, to ensure the expansion device has sufficient anchorage and beam, both ends of the board, in order to achieve the best use effect. Therefore, in the selection of telescopic device specifications, we must leave enough margin, in order to ensure the use and durability of telescopic device.

（5）当桥梁位于坡道上，固定支座一般应设在下坡方向的桥台上；

(5) when the bridge is located on the ramp, the fixed support should be located on the abutment in the downhill direction;

（6）当桥梁位于平坡上，固定支座宜设在主要行车方向的前端桥台上；

(6) when the bridge is located on the flat slope, the fixed support should be located on the front abutment of the main driving direction;

（7）固定支座宜设置在具有较大支座反力的地方；

(7) the fixed bearing should be located in the place where the counterforce is greater;

（8）在同一桥墩上的几个支座应具有相近的转动刚度；

(8) several supports on the same pier should have similar rotational rigidity;

（9）连续梁可能发生支座沉陷时，应考虑制作高度调整的可能性。

(9) the possibility of height adjustment should be taken into account when the bearing of the continuous beam may occur.

我公司生产的板式橡胶支座产品，主要包括有：普通板式支座、四氟乙烯板式支座、球冠板式橡胶支座三种产品。当在板式橡胶支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯材料时,就能制作成聚四氟乙烯滑板式橡胶支座它除了竖向钢度与弹性变形,能承受垂直荷载及适应梁端转动外,因聚四氟乙烯板的低摩擦系数,可使梁端在四氟板表面自由滑动,水平位移不受限制,特别适宜中、小荷载，大位移量的桥梁使用.我公司生产的桥梁支座产品不仅技术先进、性能优良,还具有构造简单、价格低廉、无需养护 易于更换缓冲隔震、建筑高度低等特点.因而在桥梁支座颇受欢迎,被广泛使用。

Laminated rubber bearing products produced by our company, mainly include: ordinary plate bearing, tetrafluoroethylene plate bearing, spherical rubber bearing three products. When the complex of polytetrafluoroethylene 1.5mm-3mm thick layer in the laminated rubber bearing surface, can be made of PTFE sliding plate rubber support in addition to its vertical stiffness and elastic deformation under vertical load and can adapt to Liang Duan rotation, due to the low friction coefficient of PTFE plate, the beam end in PTFE surface sliding, horizontal displacement is not restricted, especially suitable for medium and small load, large bridge shift. Our company produces bridge bearing products not only advanced technology, excellent performance, but also has the advantages of simple structure, low cost, no maintenance is easy to replace the shockproof, building height is low. So the bridge supports popular and widely used.
