電纜橋架不同角度是怎么進行連接的

橋架直線段之間、直線段與彎通、變徑直通之間的連接件,應(yīng)采用橋架制造廠配套的連接件。連接件薄鋼板厚度不應(yīng)小于橋架薄鋼板厚度。接口應(yīng)平整,無扭曲、凸起和凹陷,連接用的半園頭鍍鋅螺栓,半園頭應(yīng)在橋架內(nèi)側(cè),螺栓長度適當(dāng),擰緊之后,露出長度以2~5牙為宜。水平安裝的橋架,其直線段的連接頭,應(yīng)盡量設(shè)在兩個支吊架之間的1/4左右處。
The connectors between the straight-line sections of the bridge, between the straight-line sections and the elbow and reducer shall be the connectors matched by the bridge manufacturer. The thickness of the connecting piece steel sheet shall not be less than that of the bridge steel sheet. The interface should be flat without distortion, bulge and depression. The half round head galvanized bolt used for connection should be on the inside of the bridge. The length of the bolt should be appropriate. After tightening, the exposed length should be 2 ~ 5 teeth. For the horizontally installed bridge, the connector of the straight section should be set at about 1/4 between the two supports and hangers as far as possible.
1.一般情況下不在施工現(xiàn)場制作橋架。由于特殊原因需要時,可利用現(xiàn)有的橋架改制非標(biāo)準(zhǔn)彎通和變徑直通。改制和切斷直線段橋架時,均不得用氣、電焊切割,應(yīng)用專用切割工具。改制的橋架需要平整,及時補漆,面漆顏色應(yīng)與其它橋架相近。
1. In general, bridges are not made on the construction site. When necessary for special reasons, the existing bridge can be used to reform non-standard elbow and reducing straight. When reforming and cutting the straight-line bridge, gas and electric welding shall not be used for cutting, and special cutting tools shall be used. The restructured cable tray needs to be leveled and painted in time, and the finish color should be similar to that of other cable trays.
2.橋架跨越建筑物的伸縮縫處,按GB50168規(guī)定,應(yīng)設(shè)置伸縮縫,保證橋架及敷設(shè)在橋架內(nèi)的電纜在建筑物伸縮不危及其本身時能自由伸縮,不受損壞。因為新建建筑物里,橋架安裝一般都在混凝土結(jié)構(gòu)工程完成數(shù)月甚一年之后進行,混凝土收縮逐漸減小。伸縮量一般不會超過建筑物伸縮縫寬L。
2. At the expansion joints where the bridge crosses the building, expansion joints shall be set according to GB50168 to ensure that the bridge and the cables laid in the bridge can expand freely without damage when the expansion of the building does not endanger its own safety. Because in new buildings, the bridge installation is generally carried out months or even a year after the completion of the concrete structure project, and the concrete shrinkage gradually decreases. Generally, the expansion amount will not exceed the expansion joint width l of the building.
3.若發(fā)現(xiàn)或從土建單位了解到建筑物伸縮縫較大有可能超過L時,應(yīng)按實際做好伸縮處理。要跨越伸縮縫的橋架少一側(cè)有較長的直線段,宜超過30m,或伸縮縫兩側(cè)直線段橋架相加有30m,中間無水平或垂直彎通。以便于在橋架中留電纜(或電線)的伸縮余量,這個余量應(yīng)大于伸縮縫寬L。
3. If it is found or learned from the civil engineering unit that the expansion joint of the building is large and may exceed L, the expansion treatment shall be carried out according to the actual situation. At least one side of the bridge to cross the expansion joint has a long straight-line segment, which should be more than 30m, or the sum of the straight-line segments on both sides of the expansion joint is 30m, and there is no horizontal or vertical bend in the middle. In order to reserve the expansion allowance of cables (or wires) in the bridge, this allowance should be greater than the expansion joint width L.
