Detailed practices of bridge erection and construction:

橋架跨接線連接要注意：用抓墊、平墊或把噴塑橋架的漆刮掉再用平墊、彈簧墊壓緊。鍍鋅電纜橋架間連接板的兩端不跨接接地線，但連接板兩端不少于2個有防松螺帽或防松墊圈的連接固定螺栓強(qiáng)標(biāo)。于支架的接地，就是把支架與橋架連接處固定刮漆就可以或是抓墊。接地線小截面不小于4。

Attention should be paid to bridge spanning connection: scrape off the paint of sprayed plastic bridge frame with grasping pad, flat pad or spring pad. The two ends of the connecting plate between galvanized cable bridges do not cross the ground wire, but at least two connecting fixed bolts with anti-loosening nuts or anti-loosening washers at both ends of the connecting plate are strong. As for the grounding of the bracket, the bracket and the bridge connection can be fixed scraping paint or pad. The minimum section of grounding wire is not less than 4 square meters.

橋架的安裝：橫平豎直，彎頭處要平緩。當(dāng)橋架分層時，好用組合架。

Installation of bridge frame: horizontal and vertical, gentle elbow. When the bridge is stratified, it is better to use composite frame.

橋架內(nèi)部要加設(shè)防火封堵或加設(shè)防火包

Fire-proof plugging or fire-proof package should be added inside the bridge frame.

鋼制30米，鋁合金及塑料的15米要加伸縮節(jié)。過建筑物變形縫處伸縮縫、沉降縫加補(bǔ)償裝置。

Steel 30 meters, aluminum alloy and plastic 15 meters to add expansion joints. Expansion joints and settlement joints are compensated through the deformation joints of buildings.

橋架的支架間距一般要求水平的為1.5-3米，垂直的為2米一個。

The spacing between the supports of the bridge is generally required to be 1.5-3 meters horizontally and 2 meters vertically.

螺母位于橋架的外側(cè)。當(dāng)支架與鋁合金橋架連接時，注意防電化措施。

The nut is located outside the bridge frame. When the bracket is connected with the aluminium alloy bridge, attention should be paid to the anti-electrochemical measures.
