• Problems in installation of Jiangmen bridge and conduit

    Jiangmen bridge line pipe summed up some problems according to the daily equipment of construction brothers. Assuming that the following situations can be avoided, most errors in equipment process can be avoided. Welcome to our lively comments! 1. The whole length of metal cable tray and its bracket is not solidly grounded (2 places); 2. The elastic joint is not set according to the standard requirements; 3. The cable tray and bracket are not fixed, and the bridge bracket is not grounded jumper; 4. There is no fireproof blocking for crossing the fire compartment; 5. There is no electrochemical corrosion protection between the aluminum alloy bridge and the steel support Insulation treatment; 6, bridge elbow, tee, etc. are not used with the bridge

  • What are the purchasing methods of Jiangmen bridge conduit

    In the project, the cable tray is generally called "bridge", but the specific structural characteristics are not pointed out. The price of cable tray with different types and different production data varies greatly, and the disorder of structure type will bring problems in heat dissipation and mechanical protection at the operation site. Therefore, in the planning stage, the planning personnel should reasonably select the structural features of the cable tray according to the engineering environmental characteristics and skill requirements, and clearly express them in the type label and data sheet of the plan. 1. The selection of raw materials for Jiangmen bridge is generally divided into iron, glass fiber reinforced plastic, aluminum alloy and stainless steel. According to the different construction requirements, choose No

  • External causes of aging of Jiangmen Bridge

    The cable tray is mainly insulated by the outer layer of the cable. If the protection is not good, the external gas will be corroded for a long time, the insulation function will gradually decline, and the aging, embrittlement or falling off will not play an insulating role. The insulation on the outside of the cable is made of plastic and rubber. Sometimes aging is found. What is the reason? Then, this small series of problems of Jiangmen bridge are analyzed. 1. The insulation is affected by tide. In general, this kind of situation is more common, which usually occurs in directly buried or pipe fabric cable joints. For example, disqualification of cable joints and joints in wet weather will cause the joints to enter or mix with water vapor, and

  • Matters needing attention in welding of Jiangmen Bridge

    The construction site is the primary consideration of bridge equipment welding. Because the main girder has a certain temperature difference, camber, warpage and horizontal bending will change. Therefore, when welding in the workshop, it is better to choose the equipment Jiangmen bridge, so as not to form too big temperature difference. Bridge inspection should be carried out in the morning or at night. The orientation of the pad also affects the equipment and welding of the bridge. Because the camber of the main beam is affected by the self weight elements, the bearing of the main beam cushion is good, and the equipment is at or near the end of the main beam. In addition, bridges with smaller components should be installed on the finished beams. In order to make the equipment work normally, the equipment should be placed on the rear plate of the bridge

  • How to care for the passivation film effect of Jiangmen bridge pipe

    Generally, most of the equipment we use is of special structure, so the effect is not so strong. Therefore, we need to pay attention to avoid the oxidation phenomenon of the equipment and adopt corresponding measures to control it. Generally, when this happens, passivation or pickling process is mostly used to avoid oxygenation, so that the anti-corrosion function of C can be advanced. It can be seen that this method is still very important and plays a key role. In general, we need to choose this process when using hot-dip galvanizing, which also conforms to the aesthetic standards of other developed countries. In this case, we don't have to worry about the service life of our bridge

  • How to maintain Jiangmen bridge pipe

    Daily maintenance: use clean soft cloth to wipe surface dust regularly. Do not use wet cloth or hard objects to wipe Jiangmen bridge surface and mirror glass. Avoid contact with acids, alkaline chemicals and greasy substances. Regular repair: generally, it can be repaired once a quarter. After wiping the dust on the surface with a soft cloth, wipe it evenly with a special polishing wax, and then wipe the surface with a clean soft cloth. Hardware accessories and metal handle can be wiped with less oil and monotonous to allow flexible rotation, rust and oxidation resistance. It should be avoided to be placed in high temperature and high humidity area, and the indoor monotonous ventilation should be insisted. Avoid contact with corrosive liquids such as alcohol, nail polish and other surfaces. Should be used

  • How to improve the bearing capacity of Jiangmen Bridge

    Now, the profit margin of cable tray is gradually tightening, which is closely related to the price rise of raw materials. Therefore, in order to complete the better development, it is necessary to carry out some technological innovation, such as forward carrying ability. Next, Jiangmen bridge to the following three common cable tray said. 1. The structural strength of steel cable tray profile is higher than that of general plane plate. Jiangmen bridge generally adopts mechanical pulling or limiting technology, and then changes the plane plate shape of cable tray to advance the strength. For example, corrugated structure is selected for the bottom plate, side and cover plate of the main structure of cable tray, or

  • How to distinguish the merits and demerits of Jiangmen bridge conduit

      1) Confirmation direction: according to the layout plan of the construction, combined with the setting conditions of air-conditioning pipelines and electrical pipelines, convenient repair, and the density of cable route, the best route of Jiangmen bridge of Huixian line is recognized. Indoor, it is necessary to erect along the wall, column, beam and floor of the building as far as possible. If it is necessary to use induction pipe gallery, it should be erected in parallel above one side of the pipeline, and downlead should be considered If there is no other pipe support for borrowing, it is necessary to set up a prop by itself. 2) load Accounting: calculate the cable component per unit length on the vertical section of the trunk line of the convergence line bridge. 3) draw the plan and section of cable tray, and part of it
