Detailed implementation mode

[0033] Example 1

[0034] As Figure 1-7 shown, an energy-saving thermal insulation precast concrete roof composite system is composed of multiple energy-saving thermal insulation precast concrete roof panels.

The upper part and the periphery of the thermal insulation layer 1 are covered with a concrete layer 2. The middle of the thermal insulation layer 1 is provided with concrete ribs 3 along the length direction and the width direction, and the outside of the thermal insulation layer 1 is provided with concrete ribs 3 along the width direction. Among them, the thickness of the thermal insulation layer 1 is much larger than the thickness of the concrete layer 2, ensuring the effect of light self-weight of the roof panel.

[0035] As Figure 1-3 shown, a plurality of ring-shaped steel bars 8 are evenly distributed along the width direction on the inner side of the energy-saving thermal insulation precast concrete roof panel. The through hole orientation of the ring-shaped steel bar 8 is parallel to the width direction of the energy-saving thermal insulation precast concrete roof panel. One end of the ring-shaped steel bar 8 is exposed along the inner side of the energy-saving thermal insulation precast concrete roof panel, and the exposed part is bent obliquely downward; an inclined inner inclined surface 6 is formed on the inner side of the bottom surface of the energy-saving thermal insulation precast concrete roof panel.

[0036] As Figure 5-6 shown, among two energy-saving thermal insulation precast concrete roof panels spliced along the length direction, the ring-shaped steel bars 8 in the left energy-saving thermal insulation precast concrete roof panel and the ring-shaped steel bars 8 in the right energy-saving thermal insulation precast concrete roof panel are arranged in an alternating manner. The inner inclined surfaces 6 of the two energy-saving thermal insulation precast concrete roof panels are butted together and form a triangular notch. The horizontal steel bars 14 pass through the exposed parts of all the ring-shaped steel bars 8 in the two energy-saving thermal insulation precast concrete roof panels. The bottom of the triangular notch is laid with a thermal insulation filler 11, and the upper part is poured with cast-in-place concrete 12. The thickness of the thermal insulation filler 11 is the same as the bottom thickness of the thermal insulation layer 1.

During construction, the energy-saving heat-insulating precast concrete roof composite system is connected to the load-bearing wall 13 through the anchoring steel bars 10, and then concrete is poured into the through holes 7 to form an integral structure after solidification.

[0040] An inclined outer step 5 is formed on the outer side of the bottom surface of the energy-saving heat-insulating precast concrete roof slab; the outer side of the outer step 5 is a stepped structure made of concrete and forms an integral structure with the concrete layer 2; the inner side of the outer step 5 is the heat-insulating layer 1.
