The total length of each type of bridge and the total length of each standard bridge are calculated respectively. In addition to standard length pallets and number of pallets, increase by 1% - 2%. Column: if the column specification, the length of the bridge divided by the average column spacing is the number of columns, and then 4% of the allowance is increased by 2%. If the column specifications are different, you need to separate the statistics. This bracket is an example of the average bridge length divided by the bracket, which increases the total demand by 1% to 2%. Other parts: the number is obtained by multiplying the percentage of the bridge itself by the total.

　　嚴(yán)禁鋼橋作為人行通道、梯子或站立平臺(tái)，如果這些不僅對(duì)橋梁產(chǎn)品不利，還會(huì)帶來一些不確定因素。其支架、吊架不得作為懸掛重物的支架。在橋梁內(nèi)敷設(shè)電纜時(shí)，嚴(yán)禁將橋梁的支座和吊架作為固定吊裝裝置、傳動(dòng)裝置、滑輪和支架，吊裝時(shí)應(yīng)使用專用工具。

　　It is forbidden to use the steel bridge as a pedestrian passage, ladder or standing platform, if these are not only harmful to the bridge products, but also bring some uncertain factors. The support and hanger shall not be used as the support for hanging heavy objects. When laying cables in the bridge, it is forbidden to use the supports and hangers of the bridge as fixed hoisting devices, driving devices, pulleys and supports, and special tools shall be used for hoisting.

　　鋼橋表面涂保溫層時(shí)，應(yīng)拆除原有的表面包裝。彈簧墊圈應(yīng)安裝在電纜橋架連接螺栓上的振動(dòng)位置和電氣接地位置。

　　When the thermal insulation layer is applied on the steel bridge surface, the original surface packaging shall be removed. The spring washer shall be installed on the connecting bolt of cable tray at the vibration position and electrical grounding position.

　　安裝鋼制電纜橋架或用鋼纜盤附件合金固定。當(dāng)鋼是熱浸鋅表面時(shí)，可直接與鋁板接觸。當(dāng)表面噴有油漆或油漆粉末時(shí)，PVC或氨氣應(yīng)接觸表面和鋁板之間的隔離基作橡膠填料。對(duì)于安裝在腐蝕性環(huán)境中的鋼橋，應(yīng)采取措施防止鋼橋防護(hù)面受到損傷。切割孔后，對(duì)暴露在外的金屬表面進(jìn)行相應(yīng)的防腐涂層或油漆修補(bǔ)。

　　Install steel cable tray or fix it with steel cable tray accessory alloy. When the steel is hot-dip galvanized surface, it can directly contact with aluminum plate. When the surface is sprayed with paint or paint powder, PVC or ammonia gas shall contact the isolation base between the surface and aluminum plate as rubber filler. For the steel bridge installed in corrosive environment, measures shall be taken to prevent the steel bridge protection surface from being damaged. After cutting holes, the exposed metal surface shall be repaired with corresponding anticorrosive coating or paint.
