在安裝大跨距橋架的時(shí)候，必要根據(jù)橋架工程的預(yù)埋要求進(jìn)行安裝，如許才能將橋架固定的更加的堅(jiān)固，在橋架布線的時(shí)候應(yīng)消滅槽內(nèi)的污物和水;在部署纜線之前，檢查好橋架型號規(guī)格、路線和位置是否吻合設(shè)計(jì)要求，吻合之后在進(jìn)行安裝，為了幫助大家更好的安裝橋架，接下來山東電纜橋架廠家將為大家介紹一下橋架的非常預(yù)埋以及布線要求。

When installing the long-span bridge, it is necessary to install it according to the embedded requirements of the bridge project, so that the bridge can be fixed more firmly. When wiring the bridge, the dirt and water in the groove should be eliminated; Before deploying cables, check whether the model, specification, route and location of the cable tray meet the design requirements, and then install it. In order to help you better install the cable tray, the Shandong cable tray manufacturer will introduce the special embedment and wiring requirements of the cable tray.

① According to the design of the weak current pipeline system, the bridge support angle iron shall be pre-fired at the concrete support before the concrete is subject to anti-corrosion treatment, so as to prepare the fixing parts for the bridge installation.

②、橋架支架應(yīng)固定在支持角鐵上，支持角鐵和支架應(yīng)進(jìn)行防腐處理，以免影響混凝土質(zhì)量。

② The bridge support shall be fixed on the support angle iron, and the support angle iron and support shall be subject to anti-corrosion treatment to avoid affecting the concrete quality.

③、支、吊架安裝：

③ Installation of supports and hangers:

要求所用鋼材應(yīng)平直無顯明變形。下料后，長度誤差應(yīng)在5毫米以內(nèi)，切口不應(yīng)有卷邊或毛刺;分支和吊架應(yīng)安裝牢固，以確保水平和垂直;通常，固定支點(diǎn)之間的距離不應(yīng)大于1.5-2.0毫米.

The steel used shall be flat and straight without obvious deformation. After blanking, the length error shall be within 5mm, and the cut shall be free of curling or burr; Branches and hangers shall be installed firmly to ensure horizontal and vertical; Generally, the distance between fixed fulcrums should not be greater than 1.5-2.0 mm

在進(jìn)出接線盒、箱、柜、匝、角和丁字接頭的三個(gè)端點(diǎn)的500范圍內(nèi)，應(yīng)設(shè)置固定支架。點(diǎn)支和吊架的規(guī)格一樣平常不應(yīng)小于30毫米*3毫米扁鐵和25毫米*25毫米*3毫米扁鋼。

Fixed supports shall be set within 500 of the three ends of the junction box, box, cabinet, turn, corner and T-joint. The specification of point support and hanger shall not be less than 30mm * 3mm flat iron and 25mm * 25mm * 3mm flat steel.

大跨距橋架的布線要求

Wiring requirements for long-span bridge

橋架接線前，應(yīng)消滅槽內(nèi)的污物和水;在部署纜線，之前，應(yīng)檢查型號規(guī)格、程序、路線和位置是否吻合設(shè)計(jì)要求。

Before wiring the bridge, the dirt and water in the groove shall be eliminated; Before deploying cables, check whether the model, specification, procedure, route and location meet the design requirements.

統(tǒng)一橋中包括絕緣在內(nèi)的導(dǎo)體橫截面積之和不應(yīng)超過內(nèi)部橫截面積的40%;纜線的布料應(yīng)該是直的成都人事考試，沒有扭曲和結(jié)圈，不應(yīng)該被外力擠壓和損壞;部署前應(yīng)在纜線兩端貼上標(biāo)簽，標(biāo)明起點(diǎn)和盡頭位置;標(biāo)簽字跡應(yīng)清晰;準(zhǔn)確無誤。建筑物內(nèi)的電源線、信號電纜、雙絞線、光纜等弱電系統(tǒng)的纜線應(yīng)分開布置。

The sum of the cross-sectional areas of conductors including insulation in the unified bridge shall not exceed 40% of the internal cross-sectional area; The cable cloth should be straight and free from twists and knots, and should not be squeezed and damaged by external forces; Before deployment, labels shall be pasted on both ends of the cable to indicate the starting and ending positions; The label should be legible; Accurate. Cables for weak current systems such as power lines, signal cables, twisted pairs and optical cables in buildings shall be arranged separately.

纜線之間的凈距應(yīng)知足設(shè)計(jì)要求;部署纜線時(shí)應(yīng)提供冗余。在交接室和設(shè)備室;絞合電纜的預(yù)留長度一樣平常為3-6m。工作區(qū)是0.3到0.6米;設(shè)備端光纜的預(yù)留長度一樣平常為5-10米;如有非常要求，應(yīng)按設(shè)計(jì)要求預(yù)留長度，纜線布。
