Professional Cable Tray Manufacturer

You may have heard of aluminum alloy bridge, but you may not know much about it. 
It belongs to a kind of bridge. 
Before assembly, it is necessary to coordinate with various industries to avoid the use of large fire hoses, sprinklers, hot and cold pipes, drains and exhaust equipment. 
So do you know what the construction method of aluminum alloy cable tray vendors is? 
Next, let's take you to understand. 
1.Construction sequence measurement and positioning of the support of manufacturing components and grounding treatment of suspension bridge components. 
2.Capital construction methods and technical measures
(1)the installation position of aluminum alloy bridge is marked with spring line method, the fixed position of bracket is confirmed, and a symbol is made. 
In order to locate the bridge on the axle, you must first use the suspension method to confirm the installation reference line. 
If the reserved hole is not suitable, it must be adjusted and repaired in time. 
(2)the bracket is manufactured and assembled according to the construction drawing planning bridge and lifting specification, then the bracket is manufactured according to the measured scale, and the bracket is produced in the factory. 
If there is no ceiling, hang it along the bottom of the beam or install it on the bracket on the wall; if there is a suspended ceiling, hang it on the ceiling or install it on the bracket on the wall. 
In public places without ceilings, please combine structural components and consider beautiful structure and convenient maintenance. 
Select the wall, post support assembly, or roof truss lower chord component. 
The wall mounting bracket is fixed with expansion bolts and the distance between the brackets does not exceed 2.5 meters. 
Braces and hangers should be added at the junction of straight and non-straight parts through building deformation joints and in the middle of non-straight parts with a radius of curvature greater than 300 mm. 
The installation of brackets and hangers must ensure that the level or straightness of the bridge meets the requirements. 
3.Installation of bridges
(1)before assembling cable tray vendors, be sure to coordinate with various industries to avoid conflicts with large fire extinguishing pipes, sprinkler pipes, hot and cold pipes, water pipes, drainage, air conditioning and exhaust ducts. 
(2)for the special shape of the bridge, the on-site measuring scale is delivered to the material supplier, and the supplier will manufacture it according to the scale, thus reducing on-site processing. 
The material, type, thickness and accessories of the bridge meet the planning requirements. 
(3)the whole bridge is horizontal and vertical, neat, well spaced and well connected. 
The horizontal error in the same horizontal plane does not exceed 5mm/m, and the straightness error does not exceed 5mm/m. 
(4)raise the bridge to the predetermined position and use bolts to secure it with the bracket. 
Check the size of the turn carefully. 
The slope of the bridge must be the same as that of the building. 
The special-shaped structure of the bridge on the arch wall must have a suitable arch. 
In common with the building. 
The bridge and the bridge are connected by a connecting plate, the connecting bolt is a semicircular head bolt, and the semicircular head is on the inside of the bridge. 
The spacing between the bridges must meet the planning requirements to ensure that the bridges in the system are connected as a whole. 
(5)the bridge passing through the deformation joint of the building shall be treated with the expansion joint in accordance with the business standard "Assembly Technology of Steel Aluminum Alloy Bridge". 
When the straight section of the steel bridge exceeds 30. 
M, shrinkage compensation equipment should be installed and thermal expansion should be carried out. 
4.Grounding treatment in the aluminum alloy bridge, the galvanized connection plate can be used as the bridge to connect the whole bridge. 
Add galvanized spring washers to the two connecting bolts at both ends of the connecting plate, and connect the jumper with a flexible copper wire not less than 4mm2, then connect the jumper to the ground wire to form an electrical path. 
There should be no less than two connections between the entire bridge and the main ground wire. 
5.Multi-layer bridge components in hierarchical bridge assembly, first assemble the top layer, and then assemble the basic layer. 
There should be a certain margin between the top layer and the foundation layer, which is beneficial to the follow-up laying and maintenance of the cable. 
The clear distance between the adjacent horizontal bridges should not be less than 50mm, the distance between the layers should be not less than 150mm based on the width of the bridge, and the distance from the weak current aluminum alloy bridge should be not less than 0.5m. 
To sum up, the construction method of aluminum alloy bridge is introduced to you. 
I believe that after reading the above content, you can better understand the bridge construction.
