Cabin roof splicing structure of prefabricated cabin and combined prefabricated cabin using same

Abstract

The invention relates to a combined prefabricated cabin and a cabin roof splicing structure of the prefabricated cabin. The cabin roof splicing structure of the prefabricated cabin comprises a left cabin roof and a right cabin roof which are joint in a butted mode, I-steel bearing beams extending in the length direction of a cabin body are arranged at the butt joint positions of two cabin roof frameworks, upper wing plates and lower wing plates of the two bearing beams are respectively joint in a butted mode, webs of the two bearing beams are connected and fixed together through fastening bolts arranged in the length direction of the webs at intervals, and a supporting piece with the thickness matched with the distance between the two webs is fixedly arranged between the webs of the two bearing beams. Because I-steel is adopted as the bearing beams at the butt joint positions of the two cabin roofs and the bearing beams are fixedly connected together through the fastening bolts mounted on the webs of the bearing beams, the overall strength and the bending and deformation resistance of the cabin roofs can be guaranteed; because the supporting piece between the two webs plays a role in auxiliary positioning and auxiliary supporting in the butt joint process of the I-steel bearing beams, not only is butt joint installation facilitated, but also it can be guaranteed that the bolt connection can meet a high pre-tightening force requirement, and thus the reliability, the tightness and the rigidity of connection of the two bearing beams are improved.

Description

technical field [0001] The invention relates to a prefabricated cabin. Background technique [0002] The prefabricated cabin is an emerging modular house similar to a container. It has also been widely used in the construction of substations in the power industry because of its detachable and mobile characteristics. The prefabricated cabin of the secondary equipment is an important part of the standard distribution substation. As the carrier of the secondary equipment of the substation, the secondary equipment of the substation enters the cabin and completes the integrated debugging before leaving the factory. The construction period of the substation is shortened and the investment cost is reduced. [0003] The prefabricated cabin of secondary equipment has high requirements on appearance, strength, rigidity, sealing and heat preservation, etc. In order to save internal space and improve utilization rate, it is now necessary to provide a combined cabin type composed of dou...

Problems solved by technology

[0003] The prefabricated cabin of secondary equipment has high requirements on appearance, strength, rigidity, sealing and heat preservation, etc. In order to save internal space and improve utilization rate, it is now necessary to provide a combined cabin type composed of double cabins Prefabricated cabins, and no columns are allowed between the two cabins. After the prefabricated cabins of this structure are subjected to impact force during transportation and hoisting, the structure will be stressed, and the load-bearing beams on the span of 12 meters must be very high. strength, and when this prefabricated cabin is subjected to external forces such as strong winds and snowstorms during use, the top is very prone to deformation.
