Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings and examples.
The utility model relates to a cold insulation device of a low-temperature gas soil building tower, which comprises a support section bar 1, a support bending piece 2, a fixed screw rod 3, a sound absorption glass silk floss layer 4, a cold insulation gas gel layer 5, a micro-perforated plate layer 6 and a rectangular pipe fixing piece 7. The low-temperature gas soil tower-building cold insulation device has the main functions of having a good cold insulation effect, insulating low-temperature gas from contacting the concrete wall body 8 and having a good noise elimination effect. However, the support frame must first be designed. The supporting framework comprises a supporting section bar 1, a supporting bending piece 2, a fixing screw rod 3 and a rectangular tube fixing piece 7, wherein the rectangular tube fixing piece is located on a wall body and a sound absorption glass silk floss layer 4 which mainly plays a role in heat insulation, separates a cold air gel layer 5, and plays a role in connection and fixation between micro-perforated plate layers 6.
The supporting section bar 1 is arranged in the sound absorption glass silk floss layer 4, has the main function of supporting the whole weight of the device, and is fixed with the micro-perforated plate layer 6 together with the fixed screw rod 3; the rectangular tube fixing piece 7 has the main function of fixing the support section bar 1 and the wall body 8, and the overall strength is ensured. Preferably, the cross-section of the support profile 1 is rectangular so as to cooperate with the externally sleeved rectangular tube fixing 7 and to incorporate expansion bolts driven into the wall so that the upright support profile 1 can be fixed to the wall 8.
The support bending piece 2 has the main function of ensuring the flatness of the integral installation surface; it is connected with a supporting section bar 1 through a fixed screw rod 3.
The sound absorption glass silk floss 4 mainly has the function of sound absorption and can also have a part of cold insulation function;
the cold insulation gas gel 5 has the main function of cold insulation, and ensures that gas at a lower temperature cannot cause damage to a concrete wall;
the microperforated panel 6 main function is the protection cold insulation material direct contact air current, prevents to be blown away by the air current, can also play the effect of eliminating the noise simultaneously.
Preferably, the thickness of the glass filament layer is 100 ± 2 mm.

The cold insulation structure is a three-layer structure, namely the glass silk floss layer, the aerogel layer and the micro-perforated plate layer, and the structural design can meet the cold insulation requirement and has a good sound attenuation effect. Compared with the traditional pipeline cold insulation structure, the pipeline cold insulation structure can be applied to cold insulation in a large civil construction wall body 8, cold air can not be in direct contact with concrete, the temperature of the concrete wall surface is in a bearable temperature range, and the experimental time lasts for 12 hours.
Because the cold insulation structure adopts a three-layer structure, an anticorrosive layer and a moisture-proof layer are not required to be provided, and the structure can reduce the cost.
The utility model is used in the large-scale civil engineering tower for the first time, the specific structure and the cold insulation material can be designed and selected according to the actual requirements, and are determined according to different low-temperature requirements, so that the corresponding alternative structure and the alternative material can be found according to the actual application condition.
