Multifunctional compound disaster relief portable shelter

Abstract

The invention discloses a multifunctional compound lightweight portable shelter suitable for a disaster relief portable shelter. According to the special use requirements of the disaster relief portable shelter, four plate bodies of the portable shelter each consist of two flame retardant layers, two waterproof layers, one thermal insulation layer and one sound insulation layer, and are mainly divided into a summer thermal insulation type and a winter insulation type. The plate bodies are each composed of one layer of 3mm ultra-thin type fireproof coating layer, one layer of 2mm-thick color steel plate, one layer of 2mm-thick centrifugal glass wool spraying layer, one layer of 25mm-thick phase change material (PCM) and one layer of 2mm-thick color steel plate and 3mm ultra-thin type fireproof coating from outdoor to indoor in sequence, and the total thickness is 55 mm. Through the reasonable design of windows of the portable shelter, the fundamental improvement of the functions such asventilation and smoke extraction is realized. The novel disaster relief portable shelter has the characteristics of flame retardance, sound insulation, heat insulation, waterproof, lightweight and ventilation, flexible installation and the like, and the problems of low thermal comfort of personnel and poor indoor thermal environment in an existing disaster relief portable shelter can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a multi-functional composite disaster relief movable prefabricated house. Background technique [0002] The light prefabricated house is an environmentally friendly and economical simple house with light steel as the skeleton and sandwich panels as the enclosure material. It has the characteristics of thin structure, light weight, and quick installation. These temporary buildings played an important role in our country's earthquake relief process, providing a timely living environment for the affected people. Take the 5.12 Wenchuan Earthquake Rescue in 2008 as an example. The disaster occurred in summer. Affected by the post-disaster reconstruction project, the affected people had to live in prefabricated houses for a long time. [0003] However, due to the poor thermal performance and low thermal inertia of the current lightweight prefabricated house panels, they do ...

AI Technical Summary

Problems solved by technology

[0005] Poor thermal insulation performance: Compared with traditional brick-walled houses, prefabricated houses mostly use 50-120 mm color steel sandwich panels, which are easy to install and are conducive to mass transportation and quick use in disaster areas. Single and poor air permeability, when the solar radiation intensity is high during the day, the temperature inside the prefabricated house is higher than that outside, and the "greenhouse effect" is obvious

[0006] Weak sound insulation effect: Since the affected people need to live in the prefabricated houses for a long time, the existing prefabricated houses are thin and have no sound insulation function. Larger, causing great inconvenience to the rest and normal work and rest of the victims of the disaster

[0007] Insufficient ventilation and smoke exhaust capacity: During the disaster relief period, special personnel were responsible for eating and drinking arrangements, so they seldom lived and cooked in the prefabricated houses. Water, etc., and at the same time cause air pollution in the limited space in the prefabricated house. It is also necessary to design the ventilation and smoke exhaust function of the prefabricated house

[0008] The fire performance needs to be improved: the sandwich panels of the existing prefabricated houses are mainly extruded from rigid polyurethane, which has poor fire performance, and when polyurethane burns, it will release dense smoke containing hydrogen cyanide
