Disclosed is a node type inflated rack structure formed by connecting a plurality of independent air-tight inflating units and node devices and then filling gas. The independent air-tight inflating units are mechanically connected with the node devices through connecting rods, the independent air-tight inflating units are connected with a gas source through air inlet pipes to form an air circulation pipeline, and the mechanical joints of the independent air-tight inflating units and the node devices and the air inlet joints of the independent air-tight inflating units are mutually independent.

Air is inflated to the inflating units through one-way air inlet valves, and the air is exhausted through pressure reducing valves when the pressure in the inflating units is over high, so that a function of automatically adjusting the pressure of the air in the inflating units is realized.

本发明的加工、安装及维护方式: The processing, installation and maintenance methods of the present invention:
在生产中,将独立气密的充气单元 1 和节点装置 9
作为部件个体单独进行加工,单独进行气密性检测,合格后组装。也可在工厂分体组装,然后在现场集合总装,并可自行拆装。组装时将独立气密的充气单元 1 通过连杆 6
及节点装置 9 连接成充气子架体,再由充气子架体通过连杆 6 及节点装置 9 连接成最终的充气网架体。 In production, the airtight unit 1 and the node device 9 will be independently airtight.
The individual parts are processed separately, and the airtightness test is performed separately, and assembled after passing. It can also be assembled in the factory, and then assembled on site, and can be disassembled. Independently airtight inflator unit 1 through the connecting rod 6
And the node device 9 is connected to the inflatable sub-frame body, and then connected by the inflating sub-frame body through the connecting rod 6 and the node device 9 to form the final inflated net frame body.
充气网架建筑另外设置气体源,将气体源连接主进气管 13 ,用第二支进气管 12 ,第一支进气管 11
连通独立气密的充气单元 1 和主进气管 13 。完成搭建后进行充气。主进气管 13 、第一支进气管 11 、第二支进气管 12 的直径相对于独立气密的充气单元
1 的直径而言十分细小,依附于独立气密的充气单元 1 的表面,不会对充气网架结构的外形产生影响。因此在图 1 中,这件管路不可见。 The gas grid building is additionally provided with a gas source, the gas source is connected to the main intake pipe 13, and the second intake pipe 12 is used, and the first intake pipe 11
Connect the independently airtight inflator unit 1 and the main intake manifold 13 . Inflate after completing the construction. The diameter of the main intake pipe 13, the first intake pipe 11, and the second intake pipe 12 are relative to the independent airtight inflation unit
The diameter of 1 is very small and is attached to the surface of the independently airtight unit 1 and does not affect the shape of the inflated grid structure. So in Figure 1, this pipe is not visible.
单向进气阀 7 的开启压力可设置为 2kg (该值可根据需要选择,此处仅为实施例),当充气气压在
2kg 以上时,单向进气阀 7 开启,向充气单元 1 内充气。减压阀 10 的开启压力可设置为 2.5 ± 0.2kg
(该值可根据需要选择、调整,此处仅为实施例),当充气单元 1 内的压力过大,超过 2.5 ± 0.2kg 时,减压阀 10 开启,通过减压溢气孔 5
排气(排气时,由于单向进气阀 7 是单向阀,并不开启)。当排气使得充气单元 1 内的压力减小至减压阀 10 的开启阈值以下时,减压阀 10
关闭。从而使独立气密的充气单元 1 内的气压保持在所要求的设定值的范围之内,实现自动调节充气单元内的空气压力的功能。 The opening pressure of the one-way intake valve 7 can be set to 2kg (this value can be selected as needed, here is only the example), when the inflation pressure is
When the pressure is 2 kg or more, the one-way intake valve 7 is opened to inflate the inflation unit 1. The opening pressure of the pressure reducing valve 10 can be set to 2.5 ± 0.2kg
(This value can be selected and adjusted according to needs. This is only the embodiment.) When the pressure in the gas unit 1 is too large, exceeding 2.5 ± 0.2kg, the pressure reducing valve 10 is opened and the pressure relief hole is passed through.
Exhaust (during the exhaust, since the one-way intake valve 7 is a check valve, it does not open). The pressure reducing valve 10 is when the exhaust gas causes the pressure in the charging unit 1 to decrease below the opening threshold of the pressure reducing valve 10.
shut down. Thereby, the air pressure in the independently airtight inflator unit 1 is maintained within the range of the required set value, and the function of automatically adjusting the air pressure in the inflator unit is realized.
在充气网架结构随着气温变化,出现压力增减时,或当局部出现泄漏时,也可通过上述结构自动补气或减压,保持空气压力。
When the pressure of the inflated grid structure changes with the temperature, when the pressure increases or decreases, or when a partial leak occurs, the air pressure may be maintained by the above-mentioned structure automatically replenishing or decompressing.
以上所述的仅是本发明的优选实施方式,本发明不限于以上实施例。可以理解,本领域技术人员在不脱离本发明的精神和构思的前提下直接导出或联想到的其他改进和变化,均应认为包含在本发明的保护范围之内。
