For buildings used for machine rooms or record room, there are special requirements for floor loadings, such as higher load design values than ordinary office buildings. Therefore, it is necessary for the ordinary housing to be transformed into a computer room or record room to use or extend the original machine room.

• The floor of the machine room is strengthening with a reinforced concrete layer. Strengthening method: floor increase bearing capacity;According to the requirements of the load-bearing capacity of the machine room, the reinforced concrete reinforcement layer on the floor of the building is arranged in the form of reticulate form, and the reinforced concrete structure is extended on the circumference of the floor, so that the load of the floor is satisfied with the load-bearing requirements of the machine room. 
• The bottom of the floor of the machine room is filled with channel steel. Strengthening method: the bottom increases the load;The load can be added to the roof of the next floor of the machine room to increase the load, so that the load of the area of the machine room can reach the load bearing requirement of the new equipment, which is suitable for the extended equipment of the equipment room of the machine room which has been put into use for many years. 
• Underfloor adding channel steel in machine room. Strengthening methods: additional loading;Under the movable floor, the tank steel frame is added to the bearing beam, and the storage battery box is fixed on the channel steel so that the load of the floor can be reduced to the purpose of enlarging the load-bearing purpose of the machine room. 
• The floor surface of the machine room is thickened with steel plate. Strengthening method: dispersed bearing;The unit load of the floor of the machine room can not reach the requirement, and the load can be distributed by adding thick steel plate on the floor surface of the machine room, so that the load of the equipment can be distributed evenly on the wider ground of this layer, so as to meet the load demand of the floor.

• Pasting unidirectional carbon fiber fabric in the machine room.The carbon fiber fabric is evenly coated under the floor and bonded to the floor and beam as a whole, and the weight of the floor is transferred to the beam through the tensile of carbon fiber to improve the weight bearing method of the floor.Compared with other machine room load-bearing reinforcement schemes, carbon fiber reinforcement has high quality, high strength and high strength, and can be pasted in multi layers. After reinforcement, it does not increase the weight of the original component, and does not affect the structure shape. It is not only to improve the bearing capacity of the structure but also to strengthen the stiffness of the structure. It is widely used to reinforce the floor of the floor at present, but each scheme has its advantages. The selection of the scheme is mainly based on the project situation and the construction environment of the machine room.
