到目前為止，槽式橋架作仍為我國建設(shè)基礎(chǔ)設(shè)施的一種重要設(shè)備，在現(xiàn)代社會(huì)中的作用十分凸顯，應(yīng)用非常廣泛。通常在沒有橋架的條件下，鋪設(shè)電纜的難度非常大，在安裝槽式橋架時(shí)又該記住哪些要點(diǎn)與技巧呢？下面濟(jì)南電纜橋架廠家為您進(jìn)行分析：

Up to now, trough type cable trays are still an important equipment for infrastructure construction in China, playing a prominent role in modern society and being widely used. Usually, in the absence of a cable tray, the difficulty of laying cables is very high. What key points and techniques should be remembered when installing a trough type cable tray? The following cable tray manufacturer will analyze for you:

1

one

平直線段橋架吊架間距1.5m~2m，如果采用吊桿支架，吊桿直徑不應(yīng)小于8mm，且需在過梁處應(yīng)設(shè)置固定支架。

The spacing between the suspension brackets of the straight section bridge is 1.5m-2m. If a suspension rod support is used, the diameter of the suspension rod should not be less than 8mm, and fixed brackets should be installed at the lintel.

2

two

轉(zhuǎn)彎處兩邊各設(shè)一組吊架，且兩組吊架對稱布置，間距不大于1.5米，否則轉(zhuǎn)彎中間位置增設(shè)一組吊架。

Set up a set of hangers on both sides of the turn, and arrange the two sets of hangers symmetrically with a spacing of no more than 1.5 meters. Otherwise, add a set of hangers in the middle of the turn.

three

轉(zhuǎn)彎處兩邊各設(shè)一組吊架，且兩組吊架對稱布置，間距不大于1.5米，否則轉(zhuǎn)彎中間位置增設(shè)一組吊架；橋架距樓板距離不小于150mm，上下層橋架間距不小于150mm。

Set up a set of hangers on both sides of the turn, and arrange the two sets of hangers symmetrically with a spacing of no more than 1.5 meters. Otherwise, add a set of hangers in the middle of the turn; The distance between the top tray and the floor slab shall not be less than 150mm, and the distance between the upper and lower tray shall not be less than 150mm.

4

four

橋架、線槽按砼特殊角度準(zhǔn)確放樣、加工、安裝。

Bridge and trunking shall be accurately laid out, processed, and installed according to the special angle of concrete.

5

five

直線段鋼制電纜橋架長度超過30米、鋁合金或者玻璃鋼制電纜橋架長度超過15米設(shè)有伸縮節(jié)；電纜橋架跨越建筑物變形縫處設(shè)置補(bǔ)償裝置。

Expansion joints are provided for steel cable tray in straight section with a length of more than 30m, and aluminum alloy or glass fiber reinforced plastic cable tray with a length of more than 15m; Compensation device shall be set at the deformation joint of cable tray crossing the building.

6

six

金屬電纜橋架及其支架全長應(yīng)不少于2處于接地干線相連接；橋架首位兩端需與配電柜外殼或地線排可靠連接。

The total length of metal cable tray and its support shall not be less than 2 connected to the grounding main line; The first and two ends of the bridge should be reliably connected to the distribution cabinet shell or ground wire row.

7

seven

非鍍鋅電纜橋架間連接板的兩端跨接銅芯接地線，跨接地線一定要注意槽式橋架專用接地孔上，地線的小允許截面積不小于4mm?；連接前剔除接地螺栓下方的絕緣層；鍍鋅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(gè)有防松螺帽或防松墊圈的連接固定螺栓。

Both ends of the connecting plate between non galvanized cable tray shall be bridged with copper core grounding wires. Attention must be paid to the special grounding hole of the trough type cable tray for the bridged grounding wire. The small allowable sectional area of the grounding wire shall not be less than 4mm?; Remove the insulation layer below the grounding bolt before connection; The two ends of the connecting plate between galvanized cable trays shall not be connected to the grounding wire, but there shall be no less than two connection fixing bolts with anti loosening nuts or washers at both ends of the connecting plate.

與土建配合，橋架穿越墻體、樓板等部位預(yù)先留孔。

In coordination with civil engineering, holes should be reserved in advance for the bridge to pass through walls, floors, and other areas.

9

nine

線槽、橋架底板應(yīng)與支吊架橫擔(dān)用金屬螺栓固定（≤200mm，用一個(gè)螺栓固定；＞200mm，距邊1/4處兩個(gè)螺栓固定）。

The bottom plate of the trunking and bridge should be fixed with metal bolts to the cross arm of the support and hanger (≤ 200mm, fixed with one bolt; ＞ 200mm, fixed with two bolts at 1/4 of the edge).

10

ten

橋架穿越墻體及樓板，應(yīng)用不燃材料封堵；穿越防火分區(qū)橋架內(nèi)必須做防火封堵。

Bridge crossing walls and floors should be sealed with non combustible materials; Fire blocking must be done inside the bridge crossing the fire compartment.

室外安裝橋架安裝高度不能低于積雪、積水高度，同時(shí)考慮選用防水型蓋板，進(jìn)出室外橋架、線槽，室內(nèi)須高于室外，防止雨水流入室內(nèi)。

The installation height of outdoor cable trays should not be lower than the height of snow and water accumulation. At the same time, it is considered to use waterproof cover plates. When entering and exiting outdoor cable trays and trunking, the indoor height must be higher than the outdoor height to prevent rainwater from flowing into the indoor area.
