Specific implementation mode
As shown in Fig. 1-Figure 12, the utility model concealed beam formula connects full precast concrete harden structure, making and assembly method
It is as follows：
As shown in Figure 1, template uses the frame that surrounds of four splicing steel forms, it is each splice steel form be upper mold lath 3,
1 structure setting up and down of middle template item 2 and lower die lath, is arranged preformed hole, relatively between opposite upper mold lath 3, middle template item 2
Middle template item 2 and lower die lath 1 between preformed hole is set.According to the spacing of the size of plate and longitudinal reinforcement or transverse steel and
Diameter determines size and the aperture of upper mold lath 3, middle template item 2 and lower die lath 1.For the convenience of splicing and tight, answer
Make the aperture of preformed hole in template slightly larger than longitudinal reinforcement or the diameter of transverse steel, forms the structure of Fig. 1.
As shown in Fig. 2, first arranging four lower die laths 1 in bottom surrounding, longitudinal reinforcement 5 and transverse steel 4 are arranged
In preformed hole, longitudinal reinforcement 5 and transverse steel 4 are structure of the both ends to bending on the inside of template, longitudinal reinforcement 5 and lateral steel
The bottom edge of muscle 4 is arranged in the preformed hole between middle template item 2 and lower die lath 1, the bending of longitudinal reinforcement 5 and transverse steel 4
Section is arranged in the preformed hole between upper mold lath 3, middle template item 2, the bottom edge and bending segment of longitudinal reinforcement 5 and transverse steel 4
Between vertical section be located on the outside of template；Then four middle template items 2 are lain horizontally and is lifted on by corresponding lower die lath 1, then
