Background
The biosafety laboratory can ensure that the worker is not infested with the test subject when treating the test subject containing the pathogenic microorganisms and their toxins. The biological safety laboratory can be divided into four grades, wherein the first grade is the lowest grade, and the fourth grade is the highest grade according to different harm degrees of microorganisms and toxins thereof. When a new outbreak infectious disease occurs, besides all the huge requirements of epidemic prevention hospitals, shelter hospitals and isolation fields, the biological safety laboratory capable of carrying out virus detection experiments may have serious defects, so how to build a high-grade biological safety laboratory which is short in construction period, fast in installation and convenient to dismantle is very important. At present, most of the existing biosafety laboratories adopt traditional prefabricated building structures, and the traditional prefabricated building structures can bring about the problems of long construction period, difficult construction and difficult demolition. Therefore, the development of a high-grade biosafety laboratory which is short in construction period, rapid in installation and convenient to dismantle is urgently needed.
At present, with the technological progress and the improvement of the use requirements of people on the functions of buildings, more and more membrane structure buildings step into the vision of people. Membrane structures can be broadly classified into skeletal supported membrane structures, tensioned membrane structures, and inflatable membrane structures, in terms of support. The framework-supported membrane structure is a structural form in which steel is used as a main supporting framework and a membrane material is fixed outside the framework-supported membrane structure. The tension film structure is composed of film material, steel cable and support column, and uses the steel cable and support column to introduce tension into the film material to achieve stable structure form. The inflatable membrane structure is a structural form that membrane materials are fixed on the periphery of an enclosure structure, the air pressure in a room is raised to a certain pressure through an air supply system, so that pressure difference is generated between the interior and the exterior of a building, and air is used as a supporting element of a membrane surface to resist external force. At present, the scheme of constructing a high-grade biological safety laboratory by using a framework support type membrane structure is not reported, but the scheme of constructing a virus detection laboratory by using an inflatable membrane structure is reported, for example, a Chinese patent with the publication number of CN214210556U discloses a gas membrane structure virus detection laboratory and a biological safety laboratory, the biological safety laboratory also adopts a traditional prefabricated building structure, the design point is mainly that a plurality of gas membrane structure virus detection laboratories are arranged in the biological safety laboratory, the gas membrane structure virus detection laboratory comprises an inflatable membrane, an operation space is formed after the inflatable membrane is inflated, a transfer hole penetrates through the inflatable membrane, and the inflatable membrane is provided with a first sealing element; and the sample transfer box is provided with a second sealing piece in sealing fit with the first sealing piece, and the first sealing piece and the second sealing piece are in sealing fit so as to seal a gap between the sample transfer box and the transfer hole. However, by arranging a plurality of gas film structure virus detection laboratories and then placing the gas film structure virus detection laboratories in the biological safety laboratory, the gas film structure virus detection laboratories are very easy to burst when being subjected to external force, so that the mode of arranging a plurality of gas film structure virus detection laboratories and then placing the gas film structure virus detection laboratories in the biological safety laboratory is unsafe and is not recommended to use.
