The machine room is a place for the operation of electronic information equipment. These equipment often have large volume and high weight, so the machine room should have high load bearing capacity, meet the load bearing requirements of the equipment, and have a certain seismic resistance. But now many buildings are not built for the computer room, and the load can not meet the requirements of the computer room. At this time, the buildings in the engine room should be load-bearing and strengthening.

The importance of load-bearing strengthening in the machine room

When the weight of the cabinet, air conditioning, ups and other equipment is larger than the floor load, in order to ensure the safety of the building itself and the seismic requirements of the general engine room, you need to make a load-bearing frame for the cabinet, air conditioning, UPS battery cabinet and precision air conditioning. The load bearing bracket can disperse the floor slab to meet the design requirements of floor load capacity.

Because the machine room and other buildings are different, the machine room should develop in the direction of comprehensive, regularized and standardized when the bearing capacity is strengthened in the design and calculation of the load-bearing and strengthening of the machine room. It can refer to the calculation principle, determine the calculation method or carry on the research.

• the original component and the new part work together, at the same time it can reach the ultimate state of the bearing capacity; 

• the original component can fully play the role, and then add part of the bearing capacity to reduce; 

• the load capacity of the original component is reduced, and the post addition part fully plays a role.

Design requirements for load-bearing strengthening in machine room

Therefore, it is required that the relevant equipment such as air conditioning, UPS and battery pack in the engine room should meet the requirements of the ground load of the computer room, and design according to the specific conditions of the equipment. If a steel frame is required for bearing treatment, a detailed plan and explanation will be required. The design of equipment for distribution cabinet and fresh air blower needs to be welded by angle steel to make and install fixed support.

Load-bearing strengthening content in machine room

 The equipment density in the computer room is large, and there are special requirements for the bearing capacity of the building floor. For the functional interval of individual machine room, it is necessary to consider the load-bearing reinforcement of the floor, especially large equipment such as UPS, battery and precision air conditioning. In the layout of the engine room, the load-bearing capacity of large equipment should be mainly considered and the heavy equipment should be placed on the load-bearing beam of the engine room as far as possible. 

Requirements for ground bearing and reinforcement of the machine room

There are a lot of heavy equipment inside the computer room to reinforce the ground when placed. For example, air conditioners, minicomputers, storage cabinets, network cabinets, server cabinets, etc. These devices need to make chassis base, and the base requires the load bearing of the equipment.

The method of strengthening the load-bearing

Now the reinforcement method can be divided into： steel plate strengthening, FRP strengthening, the structural strengthening, the dismantling and strengthening of the load-bearing wall, and post installed anchor. The common methods in the machine room are the strengthening of the steel and the reinforcement of carbon fiber. The acceptance and reinforcement works of the engine room must be installed after the acceptance of the construction is qualified.
