Description

Technical Field

[0001] The utility model relates to a flat roof structure, in particular to an anti-leakage inverted flat roof structure. Background Art

[0002] An inverted roof, also known as an inverted insulated roof, is one in which the insulation layer sits above the waterproof layer. Its structural layers consist of an insulation layer, a waterproof layer, and a structural layer. The advantage of this type of roof is that the insulation protects the waterproof layer from damage such as sudden changes in outdoor temperature, UV radiation, and construction workers, thereby extending the service life of the waterproof material. Furthermore, the insulation layer of this type of roof should preferably be made of a material with low moisture absorption and strong weather resistance.

[0003] However, in the existing technology, the inverted roof structure relies on reliable waterproof materials. If the waterproof material is of poor quality, the construction process is not suitable for the on-site environment, or even the waterproof layer is not sealed and bonded with the structural layer, once the waterproof layer is damaged during the subsequent cross-operation process after completion, it will cause serious water leakage hazards. Since the waterproof layer is located below the insulation layer, the leak point cannot be found during repairs after leakage. It is very likely that the insulation layer and protective layer need to be cleaned, which is a large workload and high maintenance cost, even 5 to 10 times the cost of waterproofing. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-leakage inverted flat roof structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-leakage inverted flat roof structure, comprising a plurality of concrete roof panels, which are spliced together; a leveling layer laid on top of the concrete roof panels, a first waterproof layer laid on top of the leveling layer, a second waterproof layer laid on top of the first waterproof layer, an isolation layer laid on top of the second waterproof layer, an insulation layer laid on top of the isolation layer, and a protective layer laid on top of the insulation layer.

[0006] As a preferred technical solution of the present invention, the thermal insulation layer is made of thermal insulation materials such as extruded polystyrene.

[0007] As a preferred technical solution of the present invention, a water absorption strip is inserted into the interior of the isolation layer, a water absorption pipe is inserted into the bottom end of the water absorption strip, and both sides of the bottom end of the water absorption pipe are fixedly connected with branch pipes.

[0008] As a preferred technical solution of the present invention, the water suction pipe is connected through the leveling layer, the first waterproof layer and the second waterproof layer, and the branch pipe is located inside the leveling layer.

[0009] As a preferred technical solution of the present invention, a water-absorbing expansion strip is laid on the top of the water-absorbing strip.

[0010] As an optimal technical solution of the present invention, a waterstop steel sheet is embedded in the connection of the plurality of concrete roof panels, a micro waterstop strip is fixed on one side of the middle of the connection, and a triangular waterstop strip is fixed on the other side of the middle of the connection.

[0011] As a preferred technical solution of the present invention, a guide pipe is inserted and connected to the bottom ends of the multiple concrete roof panel connections, and an opening is opened on one side of the guide pipe, and the position of the opening is exactly opposite to the connection.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model extends the life of the waterproof layer by providing an insulation layer to protect the waterproof layer. Since the waterproof layer is protected by the insulation layer, the annual and daily temperature differences between the roof waterproof layer and the structural layer are very small, and the two are almost in a relatively constant temperature environment, which is beneficial to extending the service life of the waterproof layer, improving the indoor thermal environment, and stabilizing the indoor temperature of the top-floor room. The inverted roof structure has a waterproof layer under the thermal insulation layer and is bonded to the structural layer, which is equivalent to making a sealing layer for the concrete roof panel layer, providing good thermal protection. In this way, condensation inside the roof can be effectively prevented; it also increases the indoor heat capacity, increases the heat storage capacity, reduces room temperature fluctuations, and has a good energy-saving effect.

[0014] 2. The utility model provides water-absorbing expansion strips. When the concrete roof panel encounters water, the water enters the interior of the water-absorbing strips through the capillary-like branch pipes and the water-absorbing pipes. The water absorbed by the water-absorbing strips is absorbed by the water-absorbing expansion strips, causing the water-absorbing expansion strips to expand, thereby appearing as a bulge at the protective layer, making it convenient to find the leakage point. At the same time, micro water stop strips and triangular water stop strips are provided. When the concrete roof panel seeps water, they are adsorbed and expand, thereby squeezing the leaking gap to prevent dripping. Finally, a diversion pipe is provided. The leaking water at the connection flows into the interior of the diversion pipe through the opening and is diverted out. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a technical solution for an anti-leakage inverted flat roof structure:

[0021] Example 1:

[0022] according to Figure 1 、 Figure 2 and Figure 3 As shown, a leak-proof inverted flat roof structure includes multiple concrete roof panels 1, which are spliced together; a leveling layer 2 is laid on the top of the concrete roof panels 1, a first waterproof layer 3 is laid on the top of the leveling layer 2, a second waterproof layer 4 is laid on the top of the first waterproof layer 3, an isolation layer 5 is laid on the top of the second waterproof layer 4, an insulation layer 6 is laid on the top of the isolation layer 5, the insulation layer 6 is made of an insulation material such as extruded polystyrene, and a protective layer 7 is laid on the top of the insulation layer 6.

[0023] Furthermore, the interior of the isolation layer 5 is interspersed with a water absorption strip 8, the bottom end of the water absorption strip 8 is interspersed with a water absorption pipe 9, and both sides of the bottom end of the water absorption pipe 9 are fixedly connected with branch pipes 10. The water absorption pipe 9 is interspersed with the leveling layer 2, the first waterproof layer 3 and the second waterproof layer 4. The branch pipe 10 is located inside the leveling layer 2. A water absorption expansion strip 16 is laid on the top of the water absorption strip 8. Water enters the interior of the water absorption strip 8 through the capillary-like branch pipe 10 and the water absorption pipe 9. The water absorbed by the water absorption strip 8 is absorbed by the water absorption expansion strip 16, causing the water absorption expansion strip 16 to expand, thereby appearing as a bulge at the protective layer 7, making it convenient to find the leakage point.

[0024] Finally, a waterstop steel sheet 11 is embedded in the connection of multiple concrete roof panels 1, a micro waterstop strip 12 is fixed on one side of the middle of the connection, and a triangular waterstop strip 13 is fixed on the other side of the middle of the connection. A diversion pipe 14 is inserted and connected to the bottom end of the connection of multiple concrete roof panels 1, and an opening 15 is opened on one side of the diversion pipe 14, and the position of the opening 15 is exactly opposite to the connection. The micro waterstop strip 12 and the triangular waterstop strip 13 are adsorbed when the concrete roof panel 1 seeps water, thereby expanding, squeezing the leaking gap to prevent dripping. The leaking water at the connection flows into the interior of the diversion pipe 14 through the opening 15 and is diverted out.

[0025] In specific use, the utility model is an anti-leakage inverted flat roof structure. When constructed, the structural layers from bottom to top are: concrete roof panel 1, leveling layer 2, first waterproof layer 3, second waterproof layer 4, isolation layer 5, insulation layer 6 and protective layer 7. In the inverted roof structure, the insulation layer 6 should be made of insulation materials with low water absorption, certain strength and easy transportation and construction, such as extruded polystyrene. When the concrete roof panel 1 leaks and seeps, the accumulated water on the top of the concrete roof panel 1 will pass through The branch pipe 10 and the water absorption pipe 9 are absorbed by the water absorption strip 8, causing the water absorption expansion strip 16 to absorb water and expand. After expansion, the structural protection layer 7 above will form a bulge, which is convenient for finding the leakage point. At the same time, when the concrete roof panel 1 leaks and seeps, the micro water stop strip 12 and the triangular water stop strip 13 embedded at the connection of the concrete roof panel 1 will absorb water and expand, thereby squeezing the gap at the leakage point to prevent leakage and seepage. The leaked and seeped water flows into the interior of the diversion pipe 14 through the opening 15, and then the diversion pipe 14 is discharged.
