Specific embodiment
Embodiment 1
The full prefabricated slab of a kind of monoblock type as shown in figs. 1-7 is prefabricated including at least two pieces without support connection structure
Floor 1；Each precast floor slab 1 is both provided at least one set of non-stress Mosaic face 10 corresponded, and Mosaic face 10 includes
No.1 step 101 and No. two steps 102；The No.1 step width is A；In No. two steps of every block of precast floor slab
102 tops are both provided with several connection reinforcing bars 2, and No. two steps 102 are stretched out at the both ends of connection reinforcing bar 2, and connection reinforcing bar 2 stretches out two
Number step 102 is concordant to No.1 step outer edge, and protruding bars 2 weld respectively with additional short 20 both ends of muscle at the top of No. two steps
Afterwards, the lid pouring concrete B between two No.1 steps 101 and two No. two steps 102, makes two pieces of prefabricated chunks form entirety.
In the present embodiment, as shown in Fig. 4,6, the No.1 step of adjacent two blocks of precast floor slabs 1 is in contact, No. two platforms
Rank 102 weld with adding short muscle by connecting reinforcing bar 2 and coagulation earth mulch is used to pour such setting, is implemented without setting template
The splicing in two pieces of prefabricated chunk non-stress faces is completed with support.
Certainly, in the present embodiment, non-stress face splicing is not limited to the splicing of plate and plate, such as Fig. 5,7
Can be with the splicing of plate and bearing, i.e., the No.1 step be in contact with bearing, No. two steps top protruding bars 2 respectively with it is attached
After short 20 both ends of muscle is added to weld, between two No.1 steps 101 and two No. two steps 102 and support seat cover pouring concrete C, make
Two pieces of prefabricated chunks and bearing form entirety, be implemented without set template and support complete two pieces of prefabricated chunks have bearing it is non-by
The splicing in power face.
In the present embodiment, the non-stress bearing can be beam or wall.
Embodiment 2
A kind of embodiment as the utility model above, but be not limited thereto, as shown in Figure 7,8, which is
Two pieces of prefabricated chunks 1 have the connection of Bearing Seat Force face, form the integral prefabricated floor of plate Span Continuous stress；And the present embodiment and implementation
Example 1 difference lies in：As shown in figure 8, the No.1 step 101 of two precast floor slab is to connect to set by bearing, so
101 bottom steel bar stress 103 of No.1 step can be made to anchor into bearing, at the top of No. two steps steel bar stresses 2 by with additional bar
After the welding of both ends, the lid pouring concrete C between two No.1 steps 101 and two No. two steps 102 makes prefabricated chunk and bearing
An entirety is formed, prefabricated board lower part steel bar stress 103 in the block anchors into bearing, upper reinforcement 2 becomes the seat shoulder bar of stress
Force structure is formed, realizes connection of the prefabricated chunk in stress bearing.
In the present embodiment, i.e., single branch need to be only set in each component mounting process in the prefabricated chunk lower part at bearing
Frame positions fixation temporarily, and treating that lid pouring concrete reaches intensity can striking.
In the present embodiment, the stress bearing can be beam or wall.
Embodiment 3
A kind of full prefabricated slab of monoblock type as described in Example 1 is without support connection structure, as shown in Fig. 9,11,
Only there is one piece of prefabricated chunk 1, No.1 step 101 and the bearing of the prefabricated chunk splice, 101 bottom steel bar stress of No.1 step
103 anchor into bearing, and protruding bar 2 extends support outer by welding lengthening and meets anchorage length at the top of No. two steps, one
Number between step 101 and No. two steps 102 and support seat cover pouring concrete D；The present embodiment and embodiment 2 difference lies in：Implement
2 embodiment of example is the intermediate plate applied to precast floor slab, and the embodiment of the present embodiment is applied to the outer of precast floor slab
Edge plate, only need to be in the outside local setting template of precast floor slab, the prefabricated chunk lower part at close bearing when implementing
Single-side stand is set to position fixation temporarily, treating that lid pouring concrete reaches intensity can form removal, stent.
Certainly, in the present embodiment, it is not limited to the splicing with stress bearing, as Figure 10 can also right and wrong stress branch
The splicing of seat, i.e. the No.1 step 101 of prefabricated chunk are spliced with bearing, and protruding bar 2 is lengthened by welding at the top of No. two steps
It extends support outer and meets anchorage length, between No.1 step 101 and No. two steps 102 and support seat cover pouring concrete D；This
In embodiment the splicing of plate and stress bearing and plate with the splicing of non-stress bearing the difference is that：When plate splices with stress bearing
101 bottom steel bar stress 103 of No.1 step anchors into bearing, and plate only needs No.1 step 101 and bearing when splicing with non-stress bearing
It is in contact.
