公路桥梁伸缩缝构造要求 131 6657 0832

公路桥梁伸缩缝是建造公路桥梁时特意保留的构造,主要防止温度变化等因素影响公路桥梁的安全。

Highway bridge expansion joints are specially reserved structures when constructing highway bridges, which mainly prevent the temperature change and other factors to affect the safety of highway bridges.
要求伸缩缝在平行、垂直于桥梁轴线的两个方向,均能自由伸缩,牢固可靠,车辆行驶过时应平顺、无突跳与噪声;要能防止雨水和垃圾泥土渗入阻塞;安装、检查、养护、消除污物都要简易方便。 在设置伸缩缝处,栏杆与桥面铺装都要断开。

Requirements of expansion joints in two directions parallel and perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle had to be smooth, no sudden jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, eliminate dirt to be simple. At the expansion joint, the railing and the bridge deck should be disconnected.

GQF-C型桥梁伸缩装置
GQF-C type bridge expansion device
GQF-C型桥梁伸缩装置是适应我国公路桥梁建设的一种新型桥梁伸缩缝装置. GQF-C型桥梁伸缩装置采用整体热轧16Mn异型钢,克服了挤压异型钢直线度和集合尺寸不均匀的特点, GQF-C型桥梁伸缩装置综合技术性能和技术指标均达到或优于国际同类产品先进水平,结构型式及异型钢轧制均属国内首创,将成为交通行业标准推荐产品.
Type GQF-C bridge expansion device is adapted to a new type of bridge expansion joint of highway bridge construction in our country. The GQF-C device type bridge expansion device adopts whole hot rolled 16Mn shaped steel, overcome the extrusion special-shaped steel straightness and set size uneven, GQF-C type bridge expansion device comprehensive technical performance and technical indicators have reached or exceeded the international advanced level of similar products, structure and special-shaped steel rolling are the first domestic transportation industry will become the standard recommended products.
GQF-C型桥梁伸缩装置产品特点:建筑高度低,国产热轧整体成型异型钢材高度仅50mm,结构简单,安装方便,具有明显的可靠性,舒适性和耐久性.适用于桥面铺装层厚度等于或大于80mm,伸缩量小于等于80mm的各种桥梁,既方便旧桥梁伸缩装置更换,又可供新桥梁修建选用。
Type GQF-C bridge expansion device features: low building height, homemade hot rolled profiled steel forming the overall height of only 50mm, has the advantages of simple structure, convenient installation, obvious reliability, comfort and durability. Suitable for pavement thickness is equal to or greater than 80mm, all kinds of bridge expansion volume smaller than or equal to 80mm, which is convenient for the old bridge telescopic device replacement, and can be used for the new bridge built in the.
GQF-C型桥梁伸缩装置中间橡胶密封条其技术要求:采用氯丁橡胶(CR)密封橡胶带的伸缩装置适用与温度为-25℃-+60℃地区.采用天然橡胶(NR)密封橡胶带的装置适用于温度为-40℃-+60℃地区。

The middle type GQF-C bridge expansion device of rubber sealing strip the technical requirements: the use of chloroprene rubber (CR) sealing expansion device and temperatures for rubber belts for -25 -+60 DEG C area. The use of natural rubber (NR) sealing rubber belt device is suitable for the temperature of -40 DEG -+60 DEG area.
