Problems with installation of explosion-proof operating columns on site!
Thread Content
Our on-site operation columns here use hanging explosion-proof button boxes mounted on on-site homemade columns (No. 10 channel steel). Now I have a question to ask you! The site is steel framed. 1. What is the purpose of doing this? 2. What is a more standardized approach? 3. Why don’t you use the uprights supplied by the manufacturer? It would be better if anyone has installation drawings of the channel steel column-type explosion-proof operating column and can send one!
1. Save space. 2. Several projects I have done use hanging explosion-proof button boxes mounted on self-made columns on site (No. 10 channel steel). There are many. 3. There is no drawing. The column is 1.2 meters high, and a No. 10 channel steel is welded to the top. The length is determined according to the number of explosion-proof button boxes. I usually hang two. When ordering explosion-proof button boxes, I usually require the cable to be lowered.
Most of the ones we use are column-based
1. Convenient piping, whether it is bridge piping from the top or embedded piping from the bottom, it is very easy. 2. Is this irregular? * * The design is all like this, and the reasons for construction are very standardized when unified. 3. For the columns provided by the manufacturer, if the piping is pre-embedded from below, the cables will enter from the bottom of the column (generally cylindrical with a cable inlet below), which looks very standard and neat. However, if it is installed on the device, especially in the space above the 2nd floor, if it is a cement frame, the bridge is usually installed on this floor to facilitate piping. When piping, the protective pipe is led down from the top to the control button, and there is no way to wire it, because the supporting columns provided by the manufacturer should all have wires entering from the bottom of the column. Therefore, it is better to use channel steel as the columns. No matter how the pipes and wiring are arranged, there will be no problem.
Each factory has its own* Usually, some use cable trenches, and some use trough boxes. Cable trenches generally have operating columns, while those using trough boxes do not need operating columns.
