Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a roof waterproof and heat insulation structure comprises a roof layer 1, wherein a multilayer structure is arranged on the upper side of the roof layer 1, and comprises a foam concrete layer 11, a waterproof layer 12, a drainage layer 2 and a protective layer 13 from bottom to top. The cross section of the roof layer 1 is square, the top surface of the foamed concrete layer 11 is divided into two parts, the dividing line is a line formed by connecting the middle points of the shorter two sides of the two opposite sides of the roof layer 1, each top surface of the foamed concrete layer 11 is an inclined plane, one side of the inclined plane close to the dividing line is the highest side, and the other side of the inclined plane far away from the dividing line is the lowest side. The drainage layer 2 is also divided into two drainage layers, each drainage layer 2 is provided with a foam concrete top surface corresponding to the drainage layer, and the cross section of each drainage layer 2 is equal to the cross section of the corresponding foam concrete top surface.

As shown in fig. 3 and 4, the drainage sheet 2 (shown in fig. 2) is divided into a drainage sheet layer 21 and a drainage net 22, the drainage sheet layer 21 is composed of a plurality of unit plates 3, and the unit plates 3 are arranged on the upper surface of the foamed concrete layer 11 in a rectangular array. A drainage groove 23 is formed in one side, away from the foam concrete layer 11, of the drainage plate layer 21, and the drainage groove 23 is formed by a plurality of branch grooves in a staggered mode; the drainage net 22 is composed of a plurality of branch lines, and the drainage net 22 is embedded in the drainage groove 23. The square surrounded by the branch grooves is in a rhombus shape, the lengths of two diagonal lines of the rhombus are different, and one longer diagonal line is vertical to the side edge of the unit plate 3 which is parallel to the horizontal edge. The cross section of the branch groove is in a major arc shape, and the cross section of the branch line is larger than that of the branch groove. The drainage net 22 has a partial structure exposed outside the drainage grooves 23, so that rainwater penetrating through the protective layer 13 can be better adsorbed, and the rainwater drainage speed penetrating through the protective layer 13 is improved. Drainage channel 24 has been seted up on drainage sheet layer 21 upper surface, and drainage channel 24 is located drainage sheet layer 21 and is close to the side department that foam concrete layer 11 is far from the parting line. The drain groove 24 is parallel to the side and has the same length as the side. The drainage groove 24 is connected with the drainage groove 23, and the bottom surface of the drainage groove 24 is provided with a drainage hole 25. When rainwater penetrating through the protective layer 13 flows to the edge of the roof along the drainage grooves 23, the rainwater flows into the drainage grooves 24 and is collected, and finally is drained from the drainage holes 25 in a centralized manner, so that the drainage effect is better.

As shown in fig. 5 and 6, the strap 31 is integrally formed on both the higher side and the lower side of the unit panel 3, and the thickness of the strap 31 is equal to half of the thickness of the unit panel 3. The strap 31 on the side where the height of the cell plate 3 is high is located at the upper end of the side, and the strap 31 on the side where the height of the cell plate 3 is low is located at the lower end of the side. The length of the strap 31 is equal to the length of the side to which it is attached. A row of drainage through holes 32 are formed in the side face, with the higher height, of the unit plate 3, and the straight line, where the opening of the row of drainage through holes 32 is located, of the side face coincides with the straight line formed by connecting the midpoints of the two shorter sides of the side face. The other end of the drainage through hole 32 is positioned in the drainage groove 23 of the unit plate 3 near the lower edge of the unit plate 3. When rainwater flows to between two bridging plates 31 along the gap between two bridging plates 31, the rainwater can flow to the cell plate 3 in being close to the drainage groove 23 on lower limit through drainage through hole 32 in, can be better discharge the rainwater. Filling grooves 33 are formed in the left side and the right side of the upper surface cotton of the unit plate 3, and the depth of each filling groove 33 is smaller than half of the thickness of the unit plate 3. The sealant 34 is filled between the two adjacent left and right unit plates 3 and the filling groove 33. The sealant 34 can well seal the gap between the two adjacent left and right cell plates 3, and the width of the top surface of the sealant 34 is increased through the filling groove 33, so that the sealing effect is better. If the sealant 34 is filled in the horizontal sides, since the surface of the sealant 34 is likely to be recessed after solidification, rainwater is likely to accumulate in the grooves on the upper surface of the sealant 34, and the drainage efficiency is reduced, so that the horizontal sides are not filled with the sealant 34.

When raining, the rainwater permeates protective layer 13, flows to drainage layer 2 department, and drainage net 22 can be fine adsorb the rainwater to adsorb the rainwater that permeates protective layer 13 in drainage groove 23, and flow along drainage groove 23 downstream, discharge in the last outlet 25 from drainage groove 24. When rainwater permeates between the two adjacent upper and lower bridging plates 31, the rainwater can be stored between the lower bridging plate 31 and the unit plate 3 and flows into the drainage groove 23 along the drainage through hole 32. And two left and right adjacent overlapping plates 31 are sealed by sealant 34, so that rainwater is not easy to penetrate between the two left and right adjacent overlapping plates 31.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
