　　· 彎通：包括直角彎通、圓弧彎通等，用于橋架的轉(zhuǎn)彎處，確保電纜敷設(shè)順暢。

　　·Bends: including right angle bends, circular arc bends, etc., used at the turning points of cable trays to ensure smooth cable laying.

　　· 三通、四通：用于橋架的分支或交匯處，實(shí)現(xiàn)電纜的分路或匯流。

　　·Three way and four way: used at the branching or intersection of cable trays to achieve cable branching or convergence.

　　· 變寬板、變高板：當(dāng)橋架需要連接不同寬度或高度的段落時(shí)使用。

　　·Widening board and heightening board: used when the bridge needs to connect sections of different widths or heights.

　　2.支、吊、托架

　　2. Support, suspension, and bracket

　　· 角鋼支架：常用規(guī)格如25mm×25mm×3mm、30mm×30mm×3mm等，用于支撐橋架，可沿墻、柱或梁安裝。

　　·Angle steel bracket: commonly used specifications such as 25mm × 25mm × 3mm, 30mm × 30mm × 3mm, etc., used to support cable trays and can be installed along walls, columns, or beams.

　　· 槽鋼支架：適用于較大跨度或承載要求較高的場合，如50mm×50mm×5mm等規(guī)格。

　　·Channel steel bracket: suitable for situations with large spans or high load-bearing requirements, such as 50mm × 50mm × 5mm and other specifications.

　　· 吊架：用于懸吊橋架，可根據(jù)橋架重量和跨度選擇合適的規(guī)格，如Φ10、Φ12、Φ16等直徑的吊桿。

　　·Hanger: Used for suspending bridge frames, suitable specifications can be selected according to the weight and span of the bridge frame, such as suspension rods with diameters of Φ 10, Φ 12, Φ 16, etc.

　　· 托臂：直接支承托盤、梯架，與立柱或支架連接，有螺栓固定、卡接等多種形式。

　　·Arm support: directly supporting trays and ladders, connected to columns or brackets, with various forms such as bolt fixation and clamping.

　　3.連接件與緊固件

　　3. Connectors and fasteners

　　· 連接板：用于橋架直線段之間的連接，確保橋架的連續(xù)性和穩(wěn)定性。

　　·Connection plate: used for connecting straight sections of the bridge to ensure the continuity and stability of the bridge.

　　· 螺栓、螺母、墊圈：用于固定橋架、支吊架及連接件，螺栓規(guī)格一般為M8、M10、M12等，需配套使用平墊圈、彈簧墊圈等，防止松動(dòng)。

　　·Bolts, nuts, washers: used to fix cable trays, supports, hangers, and connectors. Bolt specifications are generally M8, M10, M12, etc., and flat washers, spring washers, etc. need to be used to prevent loosening.

　　· 接地螺栓、接地銅排：用于橋架的接地連接，確保電氣，接地螺栓直徑一般不小于M10，接地銅排截面積不小于4mm?。

　　·Grounding bolt and grounding copper bar: used for grounding connection of cable trays to ensure electrical safety. The diameter of the grounding bolt is generally not less than M10, and the cross-sectional area of the grounding copper bar is not less than 4mm?.

　　4.蓋板與封堵材料

　　4. Cover plate and sealing material

　　· 蓋板：根據(jù)橋架類型選擇相應(yīng)的蓋板，如槽式橋架的蓋板需與槽體匹配，梯式橋架的蓋板可選擇單層或雙層結(jié)構(gòu)，起到保護(hù)電纜和防塵、防潮作用。

　　·Cover plate: Select the corresponding cover plate according to the type of cable tray. For example, the cover plate of the trough type cable tray needs to match the trough body, and the cover plate of the ladder type cable tray can choose a single-layer or double-layer structure to protect the cable and prevent dust and moisture.

　　· 防火封堵材料：如防火泥、防火枕、阻火包等，用于橋架穿過防火墻、樓板等部位時(shí)的防火封堵，防止火災(zāi)蔓延。

　　·Fireproof sealing materials: such as fireproof mud, fireproof pillows, fireproof bags, etc., used for fireproof sealing when cable trays pass through firewalls, floors, and other parts to prevent the spread of fire.

　　5.輔助材料

　　5. Auxiliary materials

　　· 電纜標(biāo)示牌：用于標(biāo)識橋架內(nèi)電纜的用途、規(guī)格、走向等信息，便于維護(hù)和管理。

　　·Cable signage: used to indicate the purpose, specifications, direction, and other information of cables inside the cable tray for easy maintenance and management.

　　· 油漆、防銹漆：用于橋架及支吊架的表面防腐處理，延長使用壽命。

　　·Paint and anti rust paint: used for surface anti-corrosion treatment of cable trays and supports, extending their service life.

　　· 絕緣墊片：當(dāng)鋁合金橋架與鋼支架固定時(shí)，需使用絕緣墊片防止電化腐蝕。以上材料需根據(jù)停車場的具體規(guī)模、電纜數(shù)量、敷設(shè)要求等因素進(jìn)行精確計(jì)算和采購，確保施工順利進(jìn)行。

　　·Insulation gasket: When fixing aluminum alloy bridge and steel bracket, insulation gasket should be used to prevent electrochemical corrosion. The above materials need to be accurately calculated and purchased based on factors such as the specific size of the parking lot, the number of cables, and the laying requirements to ensure smooth construction.
