Abstract
A kind of inflation prestressing force depression bar of the invention is mainly used in building engineering field steel structure net rack depression bar and uses, and it is lightweight, and workman is easy for installation, and bearing strength is high, can give full play to the tensile property of steel；The present invention is mainly made up of power transmission lid, stack shell, aerated film, barrier film, separation, air inlet pipe, connecting bolt, and its main operational principle is：First pressure-air is input into multiple air inlet pipe, then air inlet pipe is closed, pressure-air enters in multiple separations, multiple separations apply the impartial compression of all directions to stack shell, stack shell is set to bear the ring-type tension and vertical tension of equalization, after stack shell is subject to outside axial compressive force, outside axial compressive force first passes to power transmission lid, power transmission lid is again uniformly transferred pressure to the pressure-air in separation, sub-fraction pressure transmission is to stack shell, therefore outside axial compressive force load is mainly undertaken by pressure-air, stack shell mainly undertakes the tension that pressure-air is transmitted, the tensile strength of steel is thus given full play to.
Description
Technical field
Used present invention is mainly used for building engineering field steel structure net rack depression bar.
Background technology
Current steel structure net rack axial compression member is all solid or hollow steel pole, and its compression is all undertaken by steel,
Not only steel consumption is more, and weight is big, and workman is not convenient for installing, while the pull resistance of steel can not be given full play to
Energy.
The content of the invention
Instant invention overcomes drawbacks described above, it is lightweight, and workman is easy for installation, and bearing strength is high, can give full play to steel
Tensile property；It is of the invention main by power transmission lid（1）, stack shell（2）, aerated film（3）, barrier film（4）, separation（5）, air inlet pipe（6）、
Connecting bolt（7）Composition；Upper and lower two power transmission lids（1）With stack shell（2）Welding, power transmission lid（1）Center weld have connecting bolt
（7）, air inlet pipe（6）It is welded on power transmission lid（1）Upper and and separation（5）Communicate, aerated film（3）Middle part have barrier film（4）, barrier film
（4）By aerated film（3）It is separated into multiple separations（5）；Main operational principle of the invention is：First to multiple air inlet pipe（6）Input
Pressure-air, then closes air inlet pipe（6）, the multiple separations of pressure-air entrance（5）It is interior, multiple separations（5）To power transmission lid（1）、
Stack shell（2）Apply the impartial compression of all directions, make stack shell（2）The ring-type tension and vertical tension of equalization are born, it is this
Vertical tension is exactly to stack shell（2）Vertical pre-tensile stress is applied with, works as stack shell（2）It is outside after by outside axial compressive force
Axial compressive force first pass to connecting bolt（7）And power transmission lid（1）, power transmission lid（1）Pressure is uniformly transferred to separation again（5）It is interior
Pressure-air, sub-fraction pressure transmission is to stack shell（2）, therefore the axial compressive force load of outside mainly holds by pressure-air
Load, stack shell（2）The tension that pressure-air is transmitted mainly is undertaken, the tensile strength of steel has thus been given full play to；Need explanation：
Power transmission lid（1）Thickness be that thick middle surrounding is thin and gradually transition；Aerated film（3）It is with ductility, gas impermeable material system
Make.

Specific embodiment
The content of the invention has been described in detail specific embodiment of the invention, is not repeated herein, and needs explanation：Power transmission lid 1
Thickness be that thick middle surrounding is thin and gradually transition, the concentration that this design preferably can transmit connecting bolt 7
Compressive load passes to pressure-air and stack shell 2, can avoid stress concentration phenomenon；When depression bar accidental destruction, separation 5 can be with
Releasing by parts pressure-air, it is to avoid larger personnel's injury；Connecting bolt 7 is connected with the connected ball of rack, plays transmission outside
The effect of axial compressive force.
Claims (1)
