I-shaped Honeycomb Beam and monolithic porous node of the edge of a wing of good connecting plate 6 for rectangular steel pipe.By all companies of welding of frame system
7 lower part of coupled column outer steel pipe short column of fishplate bar 6 and basis realization are affixed, and top is higher by basic 0.5m or so, then will be in steel pipe
Casting concrete is close at connecting plate 6.The coupled column rectangular steel pipe lower part that both ends weld connecting plate 6 is passed through into connecting plate 6 and height
The coupled column outer steel pipe short column 7 on ground connects out, and after all coupled column rectangular steel pipes connect, casting concrete 10 is formed
The edge of a wing is the I-shaped combination bottom column of concrete-filled rectangular steel tube.Monolithic porous node is installed, the connection of node newel post 5 is passed through
The realization of plate 6 and bottom column is reliably connected, by high-strength bolt 11 by I-shaped Honeycomb Beam that the edge of a wing is steel pipe and monolithic porous
Node connection, carries out welding appropriate to junction after connection, is installed other Vierendeel girders successively, while by rectangle in beam
The unbonded prestressing tendon arranged in steel pipe is put into steel pipe.Then the connection of two layers of steel member is equally completed with bottom.The bottom of to
Presstressed reinforcing steel 13 in layer beam carries out stretching tensioning, and anchoring temporarily is on the node rectangular steel pipe edge of a wing, and then casting concrete is extremely
Two layers of capital, it is ensured that fill up concrete 10 in column, beam and node, and guarantee the connectivity of concrete.Then construction upwards successively,
Complete three layers of connection.The unbonded prestressing tendon being arranged in two layers of beam rectangular steel pipe is arranged and is stretched tensioning, then
Two layer concretes are poured to three layers of capital, are sequentially completed the construction of top layer, bottom-up every layer of tensioning is pre- after concrete curing
Stress rib 13, it is reliable to anchor, the pre-stress construction of general frame is completed, this construction method is known as whole post stretching.Frame shape
At post-stress muscle 13, as conventional prestressed concrete frame, it is ensured that whole stress.Advantage is to construct layer by layer
Uninterruptedly, short construction period.
Embodiment 3:
Coupled column is the cross coupled column that the edge of a wing is concrete-filled rectangular steel tube in the present embodiment, and node is cross steel pipe
Monoblock type node, it is other same as Example 2.
The above-mentioned beam column edge of a wing is the construction method of the group frame system of concrete-filled rectangular steel tube:
First by design in factory's blanking, weld prefabricated institute's steel member in need, including one end be welded with connecting plate 6,
The other end is embedded in the coupled column outer steel pipe short column 7 in basis, and both ends weld the coupled column rectangle steel tubing string of connecting plate 6, both ends weldering
I-shaped Honeycomb Beam and monolithic porous node of the edge of a wing of good connecting plate 6 for rectangular steel pipe.By all companies of welding of frame system
7 lower part of coupled column outer steel pipe short column of fishplate bar 6 and basis realization are affixed, and top is higher by basic 0.5m or so, then will be in steel pipe
Casting concrete is close at connecting plate.The coupled column rectangular steel pipe lower part that both ends weld connecting plate 6 is passed through connecting plate 6 and is higher by
The coupled column outer steel pipe short column 7 on ground connects, and after all coupled column rectangular steel pipes connect, casting concrete 10 forms the wing
Edge is the cross or I-shaped combination bottom column of concrete-filled rectangular steel tube.Monolithic porous node is installed, node side is passed through
The realization of the connecting plate 6 of column 5 and bottom column is reliably connected, by high-strength bolt 11 by I-shaped Honeycomb Beam that the edge of a wing is steel pipe and whole
The connection of body formula node, carries out welding appropriate to junction after connection, is installed other Vierendeel girders successively, while will be in beam
The prestressing without bondn steel wire arranged in rectangular steel pipe is put into steel pipe.Then the company of two layers of steel member is equally completed with bottom
It connects.Stretch tensioning to the compressor wire in bottom-layer beam, anchoring temporarily on the inside of the node rectangular steel pipe edge of a wing on, then pour
Concrete is built to two layers of capital, it is ensured that fill up concrete in column, beam and node, and guarantee the connectivity of concrete, maintenance reaches
Two times tensioning is carried out to compressor wire after some strength and reaches control stress for prestressing.Form bottom prestressing combination frame body
System.Then the construction second layer will ensure that this layer of steel construction has connected in tensioning lower layer compressor wire, really to top layer successively
During stretch-draw prestressing force steel wire biggish deformation does not occur for guarantor's system.This construction method is known as two layers of methods.This is applied
Work method is not related to the binding of reinforcing bar, steel member whole prefabrication, and construction has good continuity and continuity, significantly
Shorten construction period.When span is larger, need tensioned prestressing bar 13 in fine strain of millet, in this way due to the jack for tensioning compared with
Greatly, tensioning can not be realized on the inside of the node concrete-filled rectangular steel tube edge of a wing, presstressed reinforcing steel 13 needs guiding through web in monoblock type node
Realize stretch-draw anchor in outside.When both direction requires tensioned prestressing bar, presstressed reinforcing steel 13 will arrange in advance, upper layer steel
After frame is formed, presstressed reinforcing steel 13 is stretched in interim tensioning, pours this layer concrete 10, and maintenance carries out this layer after reaching some strength
The two times tensioning of presstressed reinforcing steel 13.
