Row is removed and is recycled and reused, and plastic flexible pipe 7 is then embedded in the floor of the composition of concrete and rebar truss 1, cost
It is low, convenient to assemble and disassemble, and save the wasting of resources.
The embodiment of the present invention also provides a kind of construction method of above-mentioned type steel bar truss floor support plate composite structure, this is applied
Work method includes the following steps:
A, it is fastened with abutment 61 in one end of wirerope 6, in other end winding at ring 62, the opening of the ring 62 is logical
63 sealing of fastener is crossed, to form the perforation for squeezing into chock.
B, plastic flexible pipe 7 is hung on steel bar girder 1, and one end on wirerope 6 with ring 62 is passed through from the bottom to top
Back cord 5, end template 2 and plastic flexible pipe 7 and then end template 2 and back cord 5 are from top to bottom sequentially passed through in sides adjacent, tense steel
Cord 6 makes the abutment 61 on 6 one end of wirerope be resisted against the lower end of back cord 5,62 part of ring on 6 other end of wirerope
It is exposed to the lower end of back cord 5, then by squeezing into chock in the ring 62 on wirerope 6, to tighten wirerope 6, keeps chock steady
Admittedly the lower end of back cord 5 is resisted against, to be fixed together back cord 5, end template 2 and steel bar girder 1 to form assembled steel reinforced purlin
Frame.
C, the backbar 12 at several 1 both ends of type steel bar truss is fixedly mounted on girder steel (not by welding manner
Diagram) on, and the adjacent end template 2 on type steel bar truss 1 is subjected to alignment splicing, and to two adjacent back at spelling
Insertion installation L-type steel pin, supports L-type fashioned iron using the L-type steel pin, the L-type fashioned iron is made to be resisted against phase in through-hole on stupefied 5 side wall
Lower surface at the 2 pairs of spellings of adjacent two end templates, the splicing brim height for docking two neighboring end template 2 maintain an equal level.
D, L is unloaded after concreting is completed and meets demoulding standard in the upper surface casting concrete of end template 2
Then fashioned iron pin and L-type fashioned iron knock out 5 lower end of back cord and are placed on the chock in ring 62, by drawing supporting on 6 one end of wirerope
Block piece 61 removes end template 2 and back cord 5 to extract wirerope 6 out, completes the construction for pouring build floor.
In conclusion the present invention by between adjacent end template 2 to installing supporting element on two adjacent back cords 5 at spelling
3, and backing plate 4 is supported in the lower surface of adjacent end template 2 using supporting element 3；So that carrying out casting concrete on end template 2
When, since backing plate 4 plays counter-active effect to two adjacent end templates 2, end template 2 after bearing concrete self gravity,
Can be mutually aligned and maintaining an equal level at spelling between adjacent end template 2 guarantees the planarization of the soffit after pouring demoulding, and
And can facilitate after the completion of pouring and recycling is removed to end template 2 and back cord 5, save cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
