[0040] like Figure 1-Figure 10 As shown, an embodiment of the present application provides a roof insulation system, which is overlapped and formed on the roof of a building and waterproofs the parapet. The roof and the parapet are usually covered with a waterproof membrane 2 to play a waterproof role, and a main drainage channel 101 is usually formed on the inner side of the parapet.
[0041] In order to improve the reliability of laying the waterproof membrane 2 at the drainage part of the parapet 120, the roof insulation system also includes a drainage component 3;
[0042] The drainage assembly 3 includes a drainage pipe, a pressing sleeve 32 and a filter plate 33. The pressing sleeve 32 is inserted into the drainage pipe. The filter plate 33 is arranged at the end of the drainage pipe and covers the outside of the pressing sleeve 32. The filter plate 33 is provided with a plurality of filter holes.
[0043] The drainage pipe runs through the parapet 120 , and the waterproof membrane 2 also extends into the drainage pipe and is sandwiched between the drainage pipe and the pressure sleeve 32 .
[0044] Specifically, when installed, the drainage pipe will pass through the parapet 120 and connect to the main drainage channel 101 , so that the water inside the parapet 120 can be transported from the drainage pipe to the outside of the parapet 120 , thereby meeting the drainage requirements of the roof 110 .
[0045] The waterproofing membrane 2 laid on the roof 110 also needs to be waterproofed at the connection between the drainage pipe and the parapet 120. Usually, the waterproofing membrane 2 is laid after the drainage pipe is installed on the parapet 120. The waterproofing membrane 2 will extend into the drainage pipe, and after long-term use, it will bend due to aging and cause water leakage and failure. By further adding a compression sleeve 32 in the drainage pipe, the compression sleeve 32 can squeeze the waterproofing membrane 2 extending into the drainage pipe, so that the waterproofing membrane 2 is sandwiched between the compression sleeve 32 and the drainage pipe, so as to reduce the waterproofing membrane 2 from warping.
[0046] In addition, the compression sleeve 32 can also protect the waterproof coiled material 2 extending into the drainage pipe, thereby more effectively extending the service life of the waterproof coiled material 2 and improving the reliability of use.
[0047] Furthermore, the cross-sectional area of the drainage pipe gradually decreases along the flow direction of the water, and the outer contour of the pressing sleeve 32 matches the inner contour of the drainage pipe.
[0048] Specifically, the interior of the drainage pipe and the exterior of the pressing sleeve 32 are designed with matching conical profiles, so that after the pressing sleeve 32 is installed in the drainage pipe, the waterproof membrane 2 can be firmly squeezed onto the inner wall of the drainage pipe by the pressing sleeve 32 to improve the reliability of assembly.
[0049] Furthermore, a bent pressing plate 34 is provided at the bottom edge of the filter plate 33, and the bent pressing plate 34 is configured to press on the waterproof coiled material 2 located at the inlet position of the drainage pipe.
[0050] Specifically, the filter plate 33 can filter the water entering the drainage pipe, and the bent pressure plate 34 at the bottom of the filter plate 33 is arranged horizontally as a whole. After the filter plate 33 is assembled on the drainage pipe, the bent pressure plate 34 can press on the waterproof membrane 2 at the bottom, which can improve the laying quality of the waterproof membrane 2 on the one hand, and protect the waterproof membrane 2 on the other hand.
[0051] The filter plate 33 is detachably arranged on the drainage pipe. For example, the filter plate 33 can be installed on the drainage pipe by screws, etc., so that it is convenient for maintenance and cleaning later.
[0052] In another embodiment, the roof insulation system may further include:
[0053] At least one prefabricated insulation module 1, the prefabricated insulation module 1 comprising a plurality of insulation boards 11, two adjacent insulation boards 11 being connected to each other, the upper surfaces of the plurality of insulation boards 11 jointly forming a water guide slope 12, the water guide slope 12 extending downwardly and tilted toward the edge direction of the prefabricated insulation module 1;
[0054] The waterproof coiled material 2 is laid on the water guide slope 12 .
[0055] Specifically, the roof insulation system provided in this embodiment uses a prefabricated insulation module 1 to lay the roof 110 of the building 100 to meet the insulation requirements, and at the same time, a waterproof membrane 2 is laid on the prefabricated insulation module 1 to meet the waterproof requirements.
[0056] The prefabricated insulation module 1 is prefabricated according to the area and shape of the roof 110 of the building 100 during production. In this way, during actual paving, since the prefabricated insulation module 1 is prefabricated according to the specific roof 110, the prefabricated insulation module 1 can better match the paving requirements of the roof 110, thereby reducing the labor of workers in cutting and paving on site, thereby reducing material waste.
[0057] More importantly, the prefabricated insulation module 1 is used to directly lay the insulation board 11 on the roof 110 of the building 100, and there is no need to use perlite to find the slope during the actual construction. In this way, it is possible to avoid stopping work due to rainfall during the laying of perlite and waiting for the perlite to be completely dried before construction, thereby shortening the construction period. In addition, after the insulation board 11 of the prefabricated insulation module 1 is laid and covered with the waterproof coiled material 2, in actual use, when the waterproof coiled material 2 leaks locally, the water penetrates to the bottom of the insulation board 11, and the insulation board 11 will not diffuse the leak. In this way, when the leaking location is found in the house, it can be determined that the waterproof coiled material 2 is damaged at the top of the leaking location, which can greatly reduce the difficulty of later leak repairs.
[0058] Among them, for the insulation board 11, it can adopt the building board with insulation function used in the conventional construction process, and there is no limitation here. In addition, in order to facilitate construction, the surface of the water guide slope 12 formed by the insulation board 11 is a rough surface, and the rough surface can be achieved by coating a cement layer on the surface of the insulation board. During construction, the rough surface allows the waterproof membrane 2 to be more easily and firmly bonded to the upper surface of the insulation board 11, so as to improve the quality of construction.
[0059] When laying the insulation boards 11, two adjacent insulation boards 11 can be assembled together in an overlapping manner. For example, one edge of the insulation board 11 has an upper extension, and the other edge of the insulation board 11 has a lower extension. When the two adjacent insulation boards 11 are assembled, the upper extension of one insulation board 11 overlaps the lower extension of the other insulation board 11, thereby achieving a waterproof design at the connection between the two insulation boards 11. Alternatively, the two insulation boards 11 are assembled together in an inserting manner. For example, one edge of the insulation board 11 has a slot, and the other edge of the insulation board 11 has an insert. When the two adjacent insulation boards 11 are assembled, the insert of one insulation board 11 is inserted into the slot of the other insulation board 11, thereby achieving a waterproof design at the connection between the two insulation boards 11.
[0060] Further, the prefabricated insulation module 1 is configured to form a main drainage channel 101 between the prefabricated insulation module 1 and the parapet 120 of the building 100 after the insulation board 11 is laid on the roof 110 of the building 100;
[0061] The waterproof membrane 2 is configured to cover the surface of the main drainage channel 101 and extend to the side facade of the parapet 120 .
[0062] Specifically, in order to achieve smooth drainage of the roof 110, the prefabricated insulation module 1 adjacent to the parapet 120 of the building 100 forms a main drainage channel 101 with the parapet 120. On rainy days, rainwater falls on the water guide slope 12, and the rainwater is guided to the main drainage channel 101 by the water guide slope 12, and the rainwater is collected by the main drainage channel 101 and finally discharged through the sewer pipe.
[0063] In order to fully waterproof the roof 110 , the waterproof membrane 2 also needs to cover the surface of the main drainage channel 101 and extend to the side facade of the parapet 120 .
[0064] Furthermore, the thickness of the insulation board 11 cannot be made too thick due to the limitation of the inclination angle of the water-conducting slope 12. For a roof 110 with a large area, a plurality of the prefabricated insulation modules 1 are usually used to lay on the roof 110 of the building 100. Specifically, the roof insulation system includes a plurality of the prefabricated insulation modules 1, and a gap is formed between two adjacent prefabricated insulation modules 1;
[0065] The two adjacent prefabricated insulation modules 1 are configured such that after the insulation board 11 is laid on the roof 110 of the building 100 , the interval forms a drainage sub-channel 102 ;
[0066] The waterproof membrane 2 is also configured to cover the surface of the drainage sub-channel 102 .
[0067] Specifically, for a roof 110 with a large area, the area is usually divided, and the corresponding prefabricated insulation module 1 is laid in the corresponding area, so that the slope requirement of the water guide slope 12 can be met, and the excessive increase in the thickness of the insulation board 11 due to the large area can be avoided. A drainage sub-channel 102 will be formed between two adjacent prefabricated insulation modules 1, and the water guide slope 12 will guide the rainwater to flow into the drainage sub-channel 102, and multiple drainage sub-channels 102 are sequentially connected and converged into the drainage main channel 101 to achieve rainwater discharge.
[0068] Furthermore, the roof insulation system further comprises a drainage cover plate 13, the longitudinal section of the drainage cover plate 13 is a U-shaped structure, and the drainage cover plate 13 is arranged between two adjacent prefabricated insulation modules 1;
[0069] The waterproof membrane 2 is also laid on the surface of the drainage cover plate 13 .
[0070] Specifically, a drainage cover plate 13 is also provided in the interval formed between two adjacent prefabricated insulation modules 1. On the one hand, the drainage cover plate 13 can connect and fix the two adjacent prefabricated insulation modules 1. On the other hand, the drainage cover plate 13 can also serve to shape the drainage sub-channel 102 to carry the purpose of laying the waterproof membrane 2, which is more conducive to improving the building quality.
[0071] In order to improve the laying quality of the waterproof membrane 2, a chamfer structure is provided at the connection between the side plate and the bottom plate of the drainage cover plate 13. In addition, in order to facilitate the connection between the drainage cover plate 13 and the adjacent insulation board 11, a flange structure 131 is provided on the side plate of the drainage cover plate 13, and the flange structure 131 is overlapped on the adjacent insulation board 11.
[0072] In another embodiment, in order to improve the reliability of laying the waterproof membrane 2 on the parapet 120 at a later stage, the inner wall of the parapet 120 is provided with an upper closing groove 121 and a lower closing groove 122, and the upper closing groove 121 is arranged above the lower closing groove 122;
[0073] The waterproof membrane 2 covers the upper closing groove 121 and the lower closing groove 122 .
[0074] Specifically, after the waterproof membrane 2 covers the area where the roof 110 is located, it also needs to extend to the side wall of the parapet 120. The waterproof material is extended into the upper closing groove 121 and the lower closing groove 122 for double-layer connection and fixation, which can effectively improve the overall connection reliability and reduce the risk of the waterproof membrane 2 falling off the parapet 120 and causing water leakage during later use.
[0075] Furthermore, the waterproof membrane 2 includes an upper membrane 21 and a lower membrane 22, the upper membrane 21 is arranged on the upper surface of the lower membrane 22, the lower membrane 22 covers the parapet 120 and extends to the lower closing groove 122, and the upper membrane 21 extends into the upper closing groove 121.
[0076] Specifically, in order to improve the reliability of waterproofing, two layers of rolled materials can be laid, namely an upper layer of rolled material 21 and a lower layer of rolled material 22, wherein the lower layer of rolled material 22 is directly laid on the prefabricated insulation module 1 and also covers and extends to the parapet 120, and the upper layer of rolled material 21 is laid above the lower layer of rolled material 22 and fully covers the upper layer of rolled material 21.
[0077] To this end, the end of the lower coil 22 can be inserted into the lower closing groove 122 for fixation, and the end of the upper coil 21 can be inserted into the upper closing groove 121 for fixation.
[0078] Preferably, the upper coil 21 is provided with an overlapping portion 211 below the upper closing groove 121 , and the inner side of the overlapping portion 211 is connected to the lower closing groove 122 or the lower coil 22 .
[0079] Specifically, during actual use, the waterproof membrane 2 will expand and contract due to the influence of thermal expansion and contraction of the external environment. In order to ensure the reliability of the outermost upper membrane 21, when laying the upper membrane 21, the upper membrane 21 forms an overlapping portion 211 on one side of the parapet 120. During the later use of the overlapping portion 211, when the lower membrane 22 falls off the parapet 120 due to shrinkage, the upper membrane 21 can use the overlapping portion 211 to generate a buffer to prevent the end of the upper membrane 21 from detaching from the upper closing groove 121.
[0080] Furthermore, it also includes a closing plate 14, the longitudinal section of which is an L-shaped structure, and the side plate of the closing plate 14 is provided with an upper trough body 141 and a lower trough body 142, and the upper trough body 141 is arranged above the lower trough body 142;
[0081] The side plate of the closing plate 14 is abutted against the parapet 120 , the upper groove body 141 is located in the upper closing groove 121 , and the lower groove body 142 is located in the lower closing groove 122 ;
[0082] The waterproof membrane 2 covers the upper tank body 141 and the lower tank body 142 .
[0083] Since the construction quality between the roof 110 and the parapet 120 of the building 100 is uneven, in order to improve the laying quality of the waterproof membrane 2, a closing plate 14 can be covered on the parapet 120. The closing plate 14 can be fixed to the parapet 120 by cement or waterproof glue, and then the waterproof membrane 2 is laid outside the closing plate 14.
[0084] Similarly, a chamfered structure is provided at the connection between the side plate and the bottom plate of the closing plate 14 .
[0085] In another embodiment, after the prefabricated insulation module 1 is laid on the roof 110, in order to meet the ventilation requirements, usually, a vertically arranged exhaust pipe 15 is provided on the prefabricated insulation module 1, and a bent air outlet portion bent downward is provided at the upper end of the exhaust pipe 15, and the exhaust pipe 15 extends to the bottom of the insulation board 11. In order to ensure smooth ventilation, the drainage assembly 3 also includes a ventilation pipe 35, which is arranged on the drainage pipe, and a connecting pipe 36 is arranged on the ventilation pipe 35, and the connecting pipe 36 is located between the insulation board 11 and the roof 110 of the building 100.
[0086] Specifically, in the actual construction process, the drainage pipe can generally be installed in place when the parapet 120 is constructed. Before laying the prefabricated insulation module 1 and the waterproof membrane 2, the vent pipe 35 can be connected to the connecting pipe 36, and the connecting pipe 36 extends to the surface of the roof 110, and then covered by the prefabricated insulation module 1 above the connecting pipe 36. In later use, because the roof 110 is covered by the waterproof membrane 2, the vent pipe 35 can introduce external gas through the connecting pipe 36 into the space between the prefabricated insulation module 1 and the roof 110 to meet the ventilation and exhaust requirements of the exhaust pipe 15.
[0087] In addition, the exhaust pipe 15 is arranged to extend downwardly along the flow direction of the water flow in the drainage pipe, so that rainwater can be prevented from flowing into the space between the roof 110 and the prefabricated insulation module 1 through the exhaust pipe 15 .
[0088] The technical solution of the utility model has the following technical effects compared with the prior art: by pre-preparing at least one prefabricated insulation module according to the roof conditions of the building, the multiple insulation boards in the prefabricated insulation module will be customized for the roof of the building to be installed, so that after the multiple insulation boards are laid on the roof of the building, the upper surfaces of the multiple insulation boards will form an inclined water guide slope to meet the requirements of roof rainwater discharge, so that there is no need to use perlite for slope finding, and because of the prefabricated design, the workers' on-site cutting and paving operations are reduced, which is convenient for rapid on-site construction and assembly; and because perlite is not used, when a leak occurs, the rainwater will not flow everywhere, and the leak point can be accurately found to facilitate later repairs.
[0089] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
