Problems solved by technology

The existing common prefabricated steel structure wards are built quickly, but the air / water sealing performance is poor, the heat insulation and sound insulation performance is not good, and they cannot be used for a long time, so it is difficult to reserve in advance
In 2011, Tian Feng and others invented and disclosed an inflatable mobile isolation room CN102225032 for on-site treatment of infectious disease patients. Although it can quickly form a temporary treatment space during an epidemic, the airtightness and structural safety, stability, and durability gender needs to be improved
In 2019, Liang Huiwei proposed a negative pressure isolation ward for infectious diseases CN109424220A. This ward is independently built and has good sound insulation effect, but the construction speed is slow and the air / water tightness is poor. It is difficult to be in place in time during the outbreak period. effective service

Embodiment Construction

[0043] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0044] figure 1 It is a schematic structural diagram of the 3D printing negative pressure medical cabin in the embodiment. 3D printing can realize the construction of negative pressure medical cabins with various complex shapes. According to the topology optimization analysis under the combined working conditions of medical negative pressure, structural weight, equipment load and patient load, the medical negative pressure of the annular capsule cabin type is preferred in this embodiment. cabin, but is not limited to this form. This form of medical cabin has the advantages of reasonable force, smooth space, easy disinfectio...

Abstract

The invention discloses a construction method of a 3D printing negative pressure medical cabin based on topology optimization: according to medical requirements and working conditions, computer topology optimization technology is used to carry out space optimization design to determine the optimal space shape; according to treatment equipment and treatment Conventional methods design reserved instrument cabin windows and medical cabin windows; select printing building materials according to medical equipment storage and transportation standards, service cycles and working conditions; design printing paths and processing steps; determine the thickness of building materials and hoisting points; use 3D printing The technology can be printed in layers according to the preset structural space shape, integrated printing or segmented printing as a negative pressure medical cabin. This construction method can form a continuous airtight medical space with reasonable space stress and special-shaped structure. It has the advantages of fast construction speed, good performance, high degree of mechanization, easy transportation, assembly and combination, and meets the needs of epidemic prevention and treatment under infectious respiratory epidemics. .

Description

technical field [0001] The invention belongs to the technical fields of building materials, building structures, building construction, building design, etc., and in particular relates to a construction method of a 3D printing negative pressure medical cabin based on topology optimization. Background technique [0002] Influenza viruses and coronaviruses are ubiquitous in nature and coexist with human society for a long time. They have the characteristics of strong variability, strong seasonality, fast infectivity, and wide spread. With economic development, these viruses have induced large-scale respiratory infections in recent years. Infectious epidemics lead to frequent occurrence of global events. The treatment environment and rapid allocation of medical resources for critically ill patients in respiratory epidemics have become the most critical technical links in such epidemics, which pose a high challenge to modern medical science, construction technology and managemen...
