How to set the bridge of the elevator shaft installation project

Hello, dear, I am happy to answer for you, how to install the trapezoidal bridge of the vertical shaft Answer: First, the better step of the installation of the stepped cable tray is laid horizontally, and the standard span should be used to support, do a good job of stable foundation, and reduce the collapse of the bridge; Second, the second step of the stepped cable tray installation of the stepped cable tray and the pavement pipe and the Qingshi Road middle difference stool should have a specified small spacing, should not be laid in parallel with the pipeline below, there should be a standardized maintenance of the bridge method; 3. The third step of the installation of the stepped cable tray is that if there is a required interval between each line, optical cable cable and other routes, it cannot be paved indiscriminately; The load of the stepped cable tray and the trailer is based on the symmetry and decentralized measurement of the weight of the cable and wire. As one of the cable tray appliances, the stepped cable tray is used in many related fields.

Fourth, the actual effect of the fourth step of the stepped cable tray installation is better to support the cable, the second is to maintain the cable, and the third is to manage the cable, so when carrying out the installation of the cable tray, the specification should take its actual effect into account as the key, and carry out the installation efficiently.

The ladder bridge is generally used for the installation of the electric shaft shaft, the ladder bridge has good air permeability and heat dissipation, and the vertical installation, the cable in the ladder bridge space is easy to be fixed on the ladder.

There are two types of bridges: horizontal and vertical.

Vertical cable trays are used in cable shafts. There are also some bridge manufacturers who manufacture vertical cable shafts and vertical cable trays together, and as long as they are installed on the site, there is no need to construct cable shafts.

The control cable is laid more with trough and tray bridge.

There are many high and low voltage cables and power cables laid in electric shafts, and ladder bridges are the most suitable for them, with good heat dissipation and strong load capacity.

The stepped cable tray for the vertical shaft is because the cable is easy to be fixed on the ladder frame in the vertical space, and the stepped cable tray has the characteristics of high strength, light weight, low cost, beautiful appearance, convenient installation and good air permeability.

It is suitable for the laying of cables with large diameters, especially for the laying of high and low voltage cables with large loads.

The trapezoidal cable tray installation in the electric well needs to be bracketed, and the bracket is a bow bracket. The cable tray is divided into trough type, tray type, ladder type, grid type and other structures, which are composed of brackets, brackets and installation accessories. The bridge frame in the building can be erected independently, and can also be attached to various buildings (structures) and pipe gallery supports, which should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, all parts need to be galvanized, installed in the open air outside the building, if it is near the sea or belongs to the corrosion area, the material must have anti-corrosion, moisture resistance.

First of all, whether it is trapezoidal or trough installation, it needs to add brackets. And the bracket must be treated with anti-rust.

Secondly, the specifications and models of the installed bridge should meet the design requirements, and the vertical shaft and elevator shaft should be made of fireproof products.

Then the metal expansion bolt of the mounting bracket should be determined according to the allowable tensile and shear force and the installation hole diameter of the equipment. The bridge is connected with the bridge with galvanized bolts and the zero grounding jumper wire is installed.

Yes, the general bracket is a bow bracket.

Electric shafts can be used ladders.

cable tray.

The reasons why ladder cable trays are used in electric shaft shafts are:

1. The stepped bridge for the shaft is because the cable is easy to fix on the ladder frame in the vertical space. 2. The cascade cable tray has the characteristics of high strength, light weight, low cost, beautiful appearance, easy installation and good air permeability.

3. It is suitable for the laying of cables with large diameters, especially for the laying of high and low voltage cables with large loads.
