Depending on 21 edge of a wing of fashioned iron to the distance of the beam side concrete structure 23 of stiffness steel reinforced concrete beam 20 of property steel reinforced concrete beam 20, to enable the switching
42 end face of second end of part 40 and beam body side 232 are substantially flush；Whereby, in the adapter 40 and 50 welding of connector
Afterwards, reach in the case where fashioned iron 21 has overlapped steel bar truss floor support plate 30, the envelope template for carrying out stiffness steel reinforced concrete beam 20 is made
Industry and its subsequent concrete pouring operation.
It further, will include being set to the fashioned iron 21 relatively after the stiffness steel reinforced concrete beam 20 construction forms complete beam body
The waist muscle of two sides and concrete structure 23 outside the fashioned iron 21 and waist muscle is poured, and passes through the concrete structure 23
Define beam body side 232；At this point, the adapter 40 will be set to inside concrete structure 23 by packet, and the adapter 40
Second end 42 place beyond to the waist muscle outside, the beam body is flushed or slightly protruded from the beam body side 232
Outside side 232, second end 42 and beam body side 232 is made to form intersection, further ensures connector 50 and adapter 40 welds
Structure afterwards can go on smoothly the envelope template being arranged to casting concrete structure.
In addition, as shown in Figure 2, Figure 4 shows, on the fashioned iron 21 of the first end 41 of the adapter 40 and the stiffness steel reinforced concrete beam 20
212 weld of alar part, another weldering are equipped with a stiffener 60.Specifically, the stiffener 60 can be specification be 200mm long,
The reinforcing bar of model Ф 16 is welded in the weld of the adapter 40 with the fashioned iron 21 by bilateral fillet welding, into
The integrated structure of one step reinforcing adapter 40 and waist muscle 12.
Specifically, such as Fig. 4 and Fig. 6, the connector 50 is the L-shaped steel angle structure in cross section, the connector 50 at
Shape has longitudinal portion 501 and transverse part 502, and the joint face 51 forms on the outside in the longitudinal direction portion 501, the faying surface 52
It forms on the outside of the transverse part 502；Whereby, the connector 50 is especially by its longitudinal direction portion 501 and the adapter
40 welding, and overlapped by its transverse part 502 and the steel bar truss floor support plate 30.
In the present invention, the connector 50 after the second end 42 along beam body length direction and each adapter 40 is affixed,
One end of the connector 50 be set to shear wall on Bolted angle connection (not shown), the other end of the connector 50 then with it is huge
Angle steel on column overlaps (not shown).Wherein, specifically, the connector 50 can be the angle steel that specification is L75*7, and described
The length of connector 50 is specifically depending on the distance between shear wall and huge column.
The specific structure configuration of steel bar truss floor support plate of the present invention Yu stiffness steel reinforced concrete beam bridging arrangement is explained above, below
Conjunction please be compound refering to Fig. 2 to Fig. 6, illustrate the construction method step of aforementioned bridging arrangement.
Steel bar truss floor support plate of the present invention and the method and step of stiffness steel reinforced concrete beam lapping construction method include:
