[0027] The features and performance of the airtight joint applicable to the prefabricated pressurized space of the present application will be further described in detail below in conjunction with the embodiments.
[0028] As Figure 1 、 Figure 2 、 Figure 3 shown, an embodiment of the present application provides an airtight joint applicable to a prefabricated pressurized space, which includes a first beam body 100 and a second beam body 200 with a rectangular cross-section. On two opposite sides of the first beam body 100, a first ear plate 110 and an airtight ear plate 300 extending along its length direction are respectively provided. On the first ear plate 110, first threaded blind holes 120 arranged at intervals along its length direction, a first sealant strip groove 130 extending along its length direction, and first bolt through holes 140 arranged at intervals along its length direction are provided. The first threaded blind holes 120, the first sealant strip groove 130, and the first bolt through holes 140 are arranged in sequence as they are away from the first beam body 100. The openings of the first threaded blind holes 120 and the first sealant strip groove 130 are arranged towards the same side. The first sealant strip groove 130 is used to accommodate a sealant strip 150 that presses against the second ear plate 210;
[0029] On two opposite sides of the second beam body 200, there are respectively provided a second ear plate 210 and an airtight ear plate 300 extending along its length direction. On the second ear plate 210, there are provided second bolt through-holes 220 and second threaded blind holes 230 arranged at intervals along its length direction. The second bolt through-holes 220 are used to be connected to the first threaded blind holes 120 one by one through bolts 330, and the second threaded blind holes 230 are used to be connected to the first bolt through-holes 140 one by one through bolts 330. On the airtight ear plates 300 of the first beam body 100 and the second beam body 200, there are respectively provided second sealant strip grooves 310 extending along the length direction. The second sealant strip grooves 310 are used to accommodate a sealant strip 150;
[0030] On the airtight ear plate 300 of the first beam body 100, the openings of the second sealant strip grooves 310 are arranged on the same side as the openings of the first threaded blind holes 120 and the first sealant strip grooves 130. On the airtight ear plate 300 of the second beam body 200, the openings of the second sealant strip grooves 310 are arranged in two opposite directions with respect to the second threaded blind holes 230. When each of the first threaded blind holes 120 and each of the first bolt through-holes 140 of the first beam body 100 are connected to the corresponding second bolt through-holes 220 and the corresponding second threaded blind holes 230 of the second beam body 200 through bolts 330, the openings of the second sealant strip grooves 310 on the airtight ear plates 300 of the first beam body 100 and the second beam body 200 are arranged on the same side. The first beam body 100 and the second beam body 200 are made of stainless steel.
[0031] The airtight node applicable to the prefabricated pressurized space provided by the embodiment of the present application connects the first threaded blind holes 120 and the first bolt through-holes 140 on the first ear plate 110 provided on the side of the first beam body 100 to the second bolt through-holes 220 and the second threaded blind holes 230 on the second ear plate 210 provided on the side of the second beam body 200 through bolts 330, and enables the sealant strip 150 accommodated in the first sealant strip groove 130 provided on the first ear plate 110 to press against the second ear plate 210. It is possible to stably connect the first ear plate 110 and the second ear plate 210 together by using double-row bolts 330 that respectively pass through the first bolt through-holes 140 on the first ear plate 110 and the second bolt through-holes 220 on the second ear plate 210 and then connect to the corresponding second threaded blind holes 230 on the second ear plate 210 and the first threaded blind holes 120 on the first ear plate 110 without damaging the airtightness of the node, avoiding the transfer of air inside and outside the node through the bolt holes, and at the same time reducing the difficulty of installation and disassembly and improving the loading and unloading efficiency.
[0032] By connecting the first ear plate 110 and the second ear plate 210 with bolts 330 arranged in two rows at intervals on both sides of the first sealing strip groove 130, it can ensure uniform compression of the sealing strip 150 accommodated in the first sealing strip groove 130, increase the service life of the sealing strip 150, and at the same time make the straight-through sealing strip 150 closely fit the second ear plate 210 to improve airtightness. In addition, connecting the first ear plate 110 and the second ear plate 210 with bolts 330 arranged in two rows at intervals can also prevent the sealing strip 150 from being stressed unilaterally, thus avoiding airtight defects caused by the deflection of the first beam body 100 and the second beam body 200 on both sides.
[0033] On the opposite sides of the first beam body 100 and the second beam body 200, airtight ear plates 300 are respectively provided. A second sealing strip groove 310 is provided on the airtight ear plates 300. When each first threaded blind hole 120 and each first bolt through hole 140 of the first beam body 100 are connected to the corresponding second bolt through hole 220 and the corresponding second threaded blind hole 230 of the second beam body 200 through bolts 330, the openings of the second sealing strip grooves 310 on the airtight ear plates 300 of the first beam body 100 and the second beam body 200 are arranged facing the same side, which can facilitate the setting of the sealing strip 150 in the second sealing strip groove 310 to press against other connecting parts on both sides of the airtight node suitable for the assembled pressurized space to achieve airtight connection.
[0034] The bolts described in the embodiments of the present application include bolts, screws and other similar connecting parts.
[0035] In other alternative embodiments, a sealing strip groove for accommodating the sealing strip 150 can also be provided on the second ear plate 210 of the second beam body 200; in other alternative embodiments, sealing strip grooves can also be respectively provided on the first ear plate 110 of the first beam body 100 and the second ear plate 210 of the second beam body 200 to respectively accommodate both sides of the sealing strip 150.
[0036] The embodiments described above are some embodiments of the present application, rather than all embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.
