GQF-Z型伸缩缝厂家

The GQF-MZL model number mode bridge expansion joint device is a bridge expansion joint device designed by the hot rolled integral shaped steel. GQF-C type, GQF-Z type, GQF-L type, GQF-F type jointless bridge joint device is suitable for the expansion of the following 80mm, GQF-MZL type expansion joint device is composed of modular bridge expansion edge beam, beam, beam and linkage mechanism joint device, suitable for large and medium span bridge expansion 80mm-1200mm.

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 prominent feature of the GQF MZL expansion device is to separate the load bearing structure and the displacement control system of the telescopic device. The two forces are not interfered with each other, and the division of labor is clear. This ensures the safety of the force while ensuring the even displacement of the load.

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 use of effect. So when choosing the size of the telescopic device, we must leave enough allowance to ensure the use and durability of the 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 direction of the downhill.

（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 end 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 set in a place with large support counterforce.

（8）在同一桥墩上的几个支座应具有相近的转动刚度；

(8) several bearings on the same pier should have similar rotational stiffness;

（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) when a continuous beam may sink, the possibility of making a high adjustment should be considered.
