The intermediate region of lower edge reinforcing bar 2 is welded as a whole by the web member reinforcing bar 3 of continuous undaform constitutes the plane steel bar girder of monolithic,
Lateral surface replaces to be welded and fixed and be integrated with the 1/ lower edge reinforcing bar 2 of reinforcing bar that winds up respectively at the inflection point of 3 undaform of web member reinforcing bar, full mistake
Journey is produced by automation equipment and is completed.The wind up both ends of reinforcing bar 1 and lower edge reinforcing bar 2 are welded with common support reinforcing bar 4, each
The upper end of support reinforcing bar 4 is aligned welding with the reinforcing bar that winds up, and the length of the lower end of support reinforcing bar 4 exceeds lower edge reinforcing bar certain distance,
And extended lower edge reinforcing bar 2 with the welding of the contact position of lower edge reinforcing bar namely 4 lower end of support reinforcing bar and be welded to 13 top flange of girder steel
Surface.
As shown in figure 3, precast concrete fagging 5 is prefabricated into thin plate by armored concrete, precast concrete fagging 5 is along vertical
It is disposed to extend and is loaded in plane steel bar girder in plane steel bar girder, precast concrete fagging 5 is along own level extending direction
It is provided with multiple circular holes uniformly at intervals and punches 8 to mitigate the weight of prefabricated board, is embedded with along its length in precast concrete fagging 5
It is punched 8 W type stiffener 9 with each circular hole of S-shaped pile warp, W type stiffener 9 punches 8 settings around each circular hole, so that circle
Hole punch 8 be located at each inflection point of W type stiffener 9 at around.
The punch upper and lower surfaces of the precast concrete fagging 5 between 8 of every adjacent circular holes are provided with a reinforcing bar card
Slot 10 simultaneously constitutes a pair of of reinforcing bar card slot 10, a pair of of 10 upper and lower position face of reinforcing bar card slot, every circular hole punch 8 lower section concrete
Native 5 lower surface of fagging is additionally provided with multiple fagging supports 6.End template 11 is fixedly connected on precast concrete support by fagging support 6
5 bottom surface of plate.
The lower surface center of each fagging support 6 is provided with bolt connecting hole 7, passes through end template 11 by bolt and is connected to spiral shell
Bolt connecting hole 7, so that template 11 with precast concrete fagging 5 by being detachably connected.
As shown in Figure 4, Figure 5, each precast concrete fagging 5 successively passes perpendicularly through each plane reinforcing bar truss installa-tion and connects
Connect, every plate plane steel bar girder wind up reinforcing bar 1 and lower edge reinforcing bar 2 correspondence be inlaid in a pair of of reinforcing bar card slot 10, web member reinforcing bar 3
Pile warp reinforcing bar card slot 10 forms clamping at the inflection point of undaform, and the reinforcing bar 1 that winds up is connected to the steel of 5 upper surface of precast concrete fagging
In muscle card slot 10, lower edge reinforcing bar 2 is connected in the reinforcing bar card slot 10 of 5 lower surface of precast concrete fagging, at the same make one it is pre-
A plane steel bar girder is connected at each reinforcing bar card slot 10 of concrete fagging 5 processed, then multiple precast concrete faggings 5 with it is more
Arrange plane steel bar girder assembly connection.
As shown in figure 5, end template 11 is made of wood glue plate, bamboo slab rubber, plastic formwork or other light materials,；End template
11 are provided with through-hole in the position of corresponding bolt connecting hole 7, facilitate penetrating for bolt.The through-hole and precast concrete of end template 11 support
7 co-axially align of bolt connecting hole of plate 5 is simultaneously connected end template 11 and precast concrete fagging 5 by bolt.The plane of multi-disc
The lower end of the support reinforcing bar 4 of steel bar girder is welded on 13 top of girder steel, so that entire floor support plate is assembled on girder steel 13.
In Fig. 3, precast concrete fagging 5 is arranged at the paddy inflection point of 3 undaform of web member reinforcing bar.But in actual implementation, in advance
Concrete fagging 5 processed may be arranged at the peak inflection point of 3 undaform of web member reinforcing bar, at paddy inflection point.
Work progress of the invention is specific as follows:
For plane steel bar girder after factory process, multiple be stacked together transports building-site, saves transport
Space；Precast concrete fagging 5 can be prefabricated in the factory, then stack and transport building-site, can also be prefabricated at the scene.
End template 11 purchases existing finished product raw material, cuts and punches by design size.Building-site first presses design drawing
Multiple plane steel bar girders are vertically placed, then precast concrete fagging 5 is slightly tilted, enable precast concrete fagging 5
The design position of plane steel bar girder is penetrated, that is, is winded up in the region that reinforcing bar 1 or lower edge reinforcing bar 2 and web member reinforcing bar 3 surround, rotation
Precast concrete fagging 5 makes fagging support 6 downwards to the ground.
The position of precast concrete fagging 5 is adjusted, until the upper and lower string reinforcing bar of steel bar girder is directed at precast concrete fagging
After reinforcing bar card slot 10 on 5, precast concrete fagging 5 is become placing vertically from slant setting, steel bar girder is upper and lower at this time
The just accurately clamping in the reinforcing bar card slot 10 of precast concrete fagging 5 of string reinforcing bar repeats this movement, in plane steel bar girder
In be sequentially placed into multiple precast concrete faggings 5, to complete the assembly of plane steel bar girder Yu precast concrete fagging 5.
End template 11 is placed on to the lower section of fagging support 6, and by the reserved spiral shell of the connecting hole of end template 11 and fagging support 6
Bolt connecting hole 7 is aligned, and is then penetrated bolt and is tightened, end template 11 and precast concrete fagging 5 are connected, so far completed
The assembly of entire floor support plate.
It after entire floor support plate assembly, is lifted on girder steel 13, the support reinforcing bar 4 and girder steel of steel bar girder weld, so
The casting concrete above floor support plate afterwards.After concrete setting, end template 11 and connection bolt are removed, floor support plate is completed
Construction.It finally unscrews bolt to dismantle end template 11, end template 11 and bolt can reuse.
