Specific embodiment
As shown in Figure 1-Figure 3, the improved full prefabricated board structure fabrication process of the present invention is as follows:
As Figure 1-Figure 2, the frame that template uses four splicing steel forms to surround, each splicing steel form are cope plate
The splicing steel form that item 3, middle template item 2 and lower die lath 1 form, middle template item 2 it is upper and lower be respectively set upper mold lath 3, under
Template item 1, the face corresponding with middle template item 2 of upper mold lath 3 uniformly open up semicircle orifice 10, lower die lath 1 and middle template item 2 respectively
Corresponding face uniformly opens up semicircle orifice 10 respectively, and corresponding semicircle orifice 10 forms preformed hole.According to the size and principal rod of plate
Spacing and diameter determine size and the aperture of upper mold lath 3, middle template item 2 and lower die lath 1.In order to splice conveniently, answer
So that the aperture of preformed hole is slightly larger than the diameter of principal rod, forms the structure of Fig. 1.
As shown in Fig. 2, first arranging four lower die laths 1 in bottom, lateral stressed muscle 4 and longitudinal stress muscle 5 are intersected
It is arranged in corresponding semicircle orifice 10, lateral stressed muscle 4 and longitudinal stress muscle 5 are knot of the both ends to bending on the inside of template
The bottom edge of structure, lateral stressed muscle 4 and longitudinal stress muscle 5 is arranged in the preformed hole between middle template item 2 and lower die lath 1, horizontal
Be arranged in the preformed hole between upper mold lath 3, middle template item 2 to the bending segment of principal rod 4 and longitudinal stress muscle 5, laterally by
Vertical section between power muscle 4 and the bottom edge and bending segment of longitudinal stress muscle 5 is located on the outside of template item；Then by four middle template items
2 lie horizontally extend into inside 5 bending part of lateral stressed muscle 4 and longitudinal stress muscle respectively, then are stood in corresponding lower template
On item 1, finally four upper mold laths 3 are mounted in corresponding on template item 2 again, with bare electromagnet by lower die lath 1, in
Template item 2 and upper mold lath 3 are fixed up.
As shown in figure 3, casting concrete on the basis of Fig. 2 template and steel bar arrangement, after concrete setting 2 hours,
Bare electromagnet, upper mold lath 3, middle template item 2 and lower die lath 1 are removed, the side of full prefabricated board 6 is washed away with giant,
Keep its side surface coarse, continue to conserve, after concrete reaches expected intensity, completes the production of full precast slab.
As shown in Figure 4-Figure 6, the concealed beam formula connection structure between improved full prefabricated board of the invention and full prefabricated board and company
It is as follows to connect method:
As shown in figure 4, Z-shaped hook 8 is welded on angle steel 7, the steel angle structure with hook is formed.
As shown in figure 5, two pieces of full prefabricated boards 6 are lifted into predetermined position, keep the longitudinal stress muscle 5 on corresponding position exposed
The close dislocation lap joint in part form closing ring together, then the angle steel 7 with hook 8 is passed through into closing ring, is hung over by hook 8
On closing ring, then angle steel 7 and closing ring bound together.
As shown in fig. 6, expansive concrete 9 is poured between two pieces of full prefabricated boards 6, after concrete reaches expected intensity,
Complete the connection between two pieces of full prefabricated boards 6.
Force-transmission mechanism of the invention: the moment of flexure between full prefabricated board and full prefabricated board protrudes into two pieces of prefabricated board phases by angle steel
Exposed steel bar transmitting that mutually overlapped, two pieces of full prefabricated board exposed steel bars pass through angle steel and angle because of the mutual changing of the relative positions that transmitting moment of flexure generates
Expansive concrete among steel prevents；Shearing between full prefabricated board and full prefabricated board passes through expansive concrete and prefabricated board edge
Frictional force and prefabricated board exposed steel bar transmitting.It connects more reliable.
Embodiment the result shows that, the present invention: 1. full precast slab uses steel template, makes more environmentally friendly, conveniently；②
By exposed steel bar and Bolted angle connection between full precast slab, site operation speed is fast, the connection between full precast slab
Securely, power transmission is reliable；3. due to by the way of prefabricated and cast-in-place combination, the wet construction amount at the scene of reducing reduces field fabrication
Template number, energy conservation and environmental protection accord with the demand for development of green building, and the present invention has very big application space.
