Description

Post-disaster emergency classroom

Technical Field

The invention relates to a post-disaster emergency classroom, in particular to a post-disaster emergency classroom capable of quickly assembling classroom modules into a classroom after a disaster.

Background

Various disasters on the earth occur continuously, and the earthquakes are hundreds of times every year, so that mountain torrents burst and mountain landslides smell. When a large earthquake occurs, the civil houses and schools collapse. Where mountain torrents and landslides pass, civilian houses and schools are leveled into the ground. And rebuilding the school at least for half a year. Some children throw close to friends to transfer, some children remotely send out other schools, some children are expected in the ruins, the psychology of the children is difficult to adapt for a moment, and especially children who lose relatives are attacked.

Since disasters cannot be avoided, people can prepare the Chinese traditional medicine in advance without rain and silk. The method is characterized in that all components of a classroom are manufactured into modules and stored in a warehouse, in case of school damage caused by a disaster in a certain place, the modules are quickly transported to a disaster area, then the modules are quickly assembled into the classroom, children can remove psychological trauma caused by an earthquake for a few days, and the children can be happy to enter the school and recover from learning. And after the school is built, the module is disassembled and warehoused again for later use.

The modules that make up a classroom need to be created to facilitate transport and assembly, and to ensure safety and comfort.

After the structure is adopted, the classroom component modules are built in advance due to the fact that no rain, silk and muir exist, when a great disaster happens and the classroom is destroyed, the modules can be quickly assembled into the classroom, the time for students to interrupt school learning is greatly shortened, the high degree of personal care and the high degree of familiarity carelessness for the students by an old teacher are reflected, and the classroom component modules are beneficial to the nation and the people and are an initiative for profound consummate. This is one of the creations of the present invention.

After adopting such structure, owing to just can assemble the classroom with two axis, four corner shafts, four limit axles, and the classroom stands upright on the platform firmly, the assembling-process is simple, and the equipment speed is very fast, consuming time very short. This is the second creation of the present invention.

After adopting such structure, because set up left blackboard on the left front end board, set up right blackboard on the right front end board, left blackboard and right blackboard are close and the axial symmetry, and the classroom concatenation is accomplished the back, needn't look for the blackboard in addition, and the teacher just can go into the classroom and attend class, considers thoroughly, and is very practical. This is the third creation of the present invention.

After the structure is adopted, the left cover plate and the right cover plate of the front cover plate, the middle cover plate and the rear cover plate are connected by the steel wire ropes, and the front cover plate, the middle cover plate and the rear cover plate are connected by the inserted rods, so that the mechanical structure is reasonable, and the potential safety hazard of cover plate collapse is eliminated. This is the fourth creation of the present invention.

After adopting such structure, because the front shroud compresses tightly on the front end plate, because the back shroud compresses tightly on the back end plate, the apron has certain anti-wind ability. This is the fifth creation of the present invention.

After the structure is adopted, the three window holes are formed in the left side plate and the three window holes are formed in the right side plate, so that the lighting area of a classroom is large, air is circulated, and the learning environment is optimized. This is the sixth creation of the present invention.

After the structure is adopted, because the window hole is not embedded with glass but embedded with the solid transparent plate, the solid transparent plate cannot be crushed or shaken when being stacked and transported. This is the seventh creation of the present invention.

Disasters frequently occur in the world, schools are destroyed countless, classroom component modular design never appears, and the invention is pioneered and has wide application prospect.
