Hollow rod internal pressurization truss structure
The invention relates to a hollow rod internal pressurization truss structure. The hollow rod internal pressurization truss structure comprises an upper transverse support rod (1), a lower transversesupport rod (7), a right supporting point (5), a left supporting point (8), a middle upright support rod (11), side upright support rods (12) and oblique support rods (13), and is characterized in that the upper transverse support rod (1), the lower transverse support rod (7), the middle upright support rod (11), the side upright support rods (12) and the oblique support rods (13) are all hollow rods; and all the hollow rods are filled with a medium for applying an internal pressure. By means of application of an internal pressure to a building cavity, the strength of a structural body is enhanced without increasing the size and weight of the material of the structural body. If the medium applying the pressure is gas, the increased gas weight is negligible. If the medium is liquid with a relatively large volume weight, the medium can be selectively used under the situation that counterweight is needed such as the structures of tunnel protection bodies, well pile casings, trunks and thelike.
本发明涉及一种中空杆内加压桁架结构，包括上横支撑杆（1）、下横支撑杆（7）、右支点（5）、左支点（8）、中立支撑杆（11）、侧立支撑杆（12）及斜支撑杆（13），其特征在于：所述的上横支撑杆（1）、下横支撑杆（7）、中立支撑杆（11）、侧立支撑杆（12）及斜支撑杆（13）均为中空杆，中空杆内均充有介质，施加内压力。本发明通过给构筑物空腔施加内压，提高了结构体的强度，而不增加本身材料的体积和重量，若施加压力的介质是气体，增加的气体重量可以忽略不计；若介质是容重较大的液体，可以选择使用在需要配重的情况如隧道防护体、井护筒、围井等结构。
