Sealing connection structure used for expanding and splicing different modules or capable of increasing and reducing pressure

Abstract

The invention relates to a sealing connection structure for expanding and splicing different modules or capable of increasing and reducing pressure. The sealing connection structure comprises a four-way framework, a window frame, a door frame, a flexible airtight connector and a standard flange. The four-way framework is of a three-dimensional structure with the upper surface and the lower surface sealed and the four side vertical surfaces opened. The sealing connection structure is based on the four-way framework, a plurality of window frames are mounted on the four-way framework to form connection node cabins in different forms, or a plurality of window frames and a door frame are mounted on the four-way framework to form a transition cabin. The connecting node cabin is used for building group expansion, and the transition cabin is a closed pressure increasing and reducing space; connection and mounting adjustment between the connection node cabin or the transition cabin and other cabin body modules of the building group are achieved through flexible airtight connection and standard flanges, the standard flanges are mounted on the four-way framework, and the standard flanges are connected through flexible airtight connection. The problem of splicing and grouping different cabins can be solved, so that a combined building space is conveniently built, and the requirements of people for living, working and the like are met.

Description

technical field [0001] The invention relates to the technical field of buildings in high-altitude areas, and in particular to a sealed connection structure for expansion splicing of different modules or variable pressure and pressure reduction. Background technique [0002] High-altitude areas have low temperature and severe cold all year round, thin air, low atmospheric pressure and oxygen content, and harsh geographical and climatic conditions. When people in plain areas enter high-altitude areas for living or economic and social construction, most of them will experience rapid heart rate, dizziness, and decreased physical fitness. Altitude sickness such as dehydration endangers the work efficiency and quality of life of personnel, and even causes damage to human physiological functions in severe cases. The pressurized oxygen supply buildings (groups) can effectively solve the altitude sickness of personnel. Most of the existing pressurized oxygen supply cabins are indepen...

AI Technical Summary

Problems solved by technology

The pressurized oxygen supply buildings (groups) can effectively solve the altitude sickness of personnel. Most of the existing pressurized oxygen supply cabins are independent. Under such circumstances, there is a large workload and difficulty in establishing a confined space, so the volume of the independent cabin is greatly limited, and it is difficult to meet the needs of personnel for living and office.
