The installation of cable tray needs certain accessories. The following four materials for the installation of cable tray in Shandong Province are summarized.

(1)橋架：分別統(tǒng)計出各種型號規(guī)格橋架的全長,除一該橋架的標準長度,得出橋架的數(shù)量外,再增加1%－2%的余量。

(1) Bridge frame: The total length of each type and specification of the bridge is calculated separately. In addition to the standard length of the bridge, the number of the bridge frame is obtained, and the remaining amount is increased by 1%-2%.

(2)立柱：如采用統(tǒng)一規(guī)格的立柱,可用橋架全長除以平均立柱間距,得出立柱數(shù),再增加2%～4%余量。如立柱規(guī)格不一,則需分別統(tǒng)計。

(2) Columns: If the column of uniform specification is adopted, the total length of the bridge can be divided by the average spacing of the columns, and the number of columns can be obtained, and the remaining amount can be increased by 2%-4%. If column specifications are different, statistics should be made separately.

(3)托臂：橋架全長除以托臂平均間距,再增加1%～2%余量,極為總需量。

(3) Brackets: The total length of the bridge is divided by the average spacing of brackets, and the additional 1%-2% is needed.

(4)其它部件：按其主體數(shù)乘以一定比例(視總廠而定)求得其總數(shù)。

(4) Other parts: multiply the number of main parts by a certain proportion (depending on the factory) to get the total number.
