Description

Technical Field

[0001] This invention relates to the field of ultra-low energy buildings, and more particularly to a connection structure for the exterior door of the roof layer and the roof insulation and waterproofing system of ultra-low energy buildings. Background Technology

[0002] Ultra-low energy buildings implement a thermal bridge-free design concept. To minimize the impact of thermal bridges formed at various nodes on building quality, some special structures have been developed. Among them, the external installation of doors and windows is a representative example. In particular, the installation of external doors involves not only considering factors such as thermal bridges and airtightness, but also often involves connections with underground or roof insulation and waterproofing systems. The construction method is not only complex, but also greatly affects the construction progress. It requires the coordinated work of insulation construction, waterproofing construction, and external door and window construction to meet the performance requirements of waterproofing, insulation, and airtightness at this node. In practice, multi-party coordination is not only difficult to achieve, but it is also difficult to agree on the production cycle of materials on site. Moreover, due to the intersection of multiple systems, if it is necessary to replace external doors and windows later, it is necessary to damage the original building's underground external wall insulation system and waterproofing system, causing unnecessary losses.

[0003] For example, the prior art CN109653452A discloses a passive ultra-low energy consumption dry-operation roof insulation and waterproofing integrated construction method, which includes the following steps: ① leveling and sloping the roof to form a clean, dry concrete structural base layer with a slope >2%; ② applying a cold primer to the dry concrete structural base layer to form a cold primer base treatment layer; ③ cold self-adhesive installation of a self-adhesive acid and alkali resistant aluminum foil modified bitumen air-barrier membrane layer on a coated profiled steel sheet base layer or on the previous cold primer base treatment layer; ④ bonding and installing an insulation layer on the self-adhesive acid and alkali resistant aluminum foil modified bitumen air-barrier membrane layer with foaming adhesive (specifically, solvent-free single-component polyurethane foam adhesive); ⑤ bonding a self-adhesive fireproof modified bitumen waterproof membrane layer on top of the insulation layer; ⑥ laying a slate surface waterproof membrane layer on top of the self-adhesive fireproof modified bitumen waterproof membrane layer using a blowtorch hot-melt welding. The roof slope and leveling process involves using cement grout to achieve a flatness tolerance of ≤5mm. The surface should be flat, dense, and smooth, free from hollow areas, cracks, looseness, sandiness, peeling, or flaking. The moisture content of the concrete substrate should not exceed 9%. This construction method only applies to the roof's thermal insulation and waterproofing system and does not reflect the connection between the roof system and other parts of the building.

[0004] To address the aforementioned issues, this invention provides a connection structure suitable for the rooftop exterior door and roof insulation and waterproofing system of ultra-low energy consumption buildings. This further optimizes the construction process between the rooftop exterior door installation and the roof insulation and waterproofing system, ensuring the relative independence of the rooftop exterior door installation and the roof insulation and waterproofing system construction, and reducing the quality risks caused by overlapping procedures. Utility Model Content

[0005] To ensure the effective connection between the installation of rooftop exterior doors and the roof insulation and waterproofing system in ultra-low energy consumption buildings, this invention provides a connection structure suitable for rooftop exterior doors and roof insulation and waterproofing systems in ultra-low energy consumption buildings. Through a reasonable construction method, the requirements for thermal bridging and airtightness of rooftop exterior door installation are met at the same time, while forming an effective connection with the roof insulation and waterproofing system, reducing the risks caused by construction overlap.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connection structure for the exterior door of an ultra-low energy consumption building rooftop and its roof insulation and waterproofing system includes a rooftop exterior door threshold, a building roof slab, a vapor barrier membrane, a roof insulation layer, a first waterproof membrane, an upturned insulation layer, a first upturned waterproof membrane, a second waterproof membrane, a second upturned waterproof membrane, a continuous thermal insulation strip, a rooftop exterior door, an EPDM waterproof and breathable membrane, an EPDM waterproof vapor barrier membrane, an additional insulation layer, and an additional waterproof membrane.

[0016] Furthermore, the second waterproof membrane overlaps above the overlap surface between the first upturned waterproof membrane and the first waterproof membrane;

[0017] Furthermore, the second layer of upturned waterproof membrane is fully adhered to the outside of the first layer of upturned waterproof membrane;

[0018] Furthermore, the second layer of upturned waterproof membrane is overlapped on the outside of the roof layer door threshold, with an overlap width of not less than 100mm;

[0019] Furthermore, the second layer of waterproof membrane is overlapped on the second layer of waterproof membrane, with an overlap width of not less than 200mm;

[0020] Furthermore, the continuous thermal insulation strip is fixed to the outside of the roof layer door threshold;

[0021] Furthermore, the outer door of the roof layer is fixed to the continuous thermal insulation strip;

[0022] Furthermore, one end of the EPDM waterproof vapor barrier membrane is attached to the inside of the outer door threshold of the roof layer, and the other end is attached to the outer door frame of the roof layer.

[0023] Furthermore, one end of the EPDM waterproof and breathable membrane is attached to the outside of the roof layer door threshold, and the other end is attached to the roof layer door frame.

[0024] Furthermore, the additional insulation layer fills the gap between the continuous thermal insulation strip and the upward-turned insulation layer;

[0025] Furthermore, the additional insulation layer should cover the entire length of the thermal insulation strip;

[0026] Furthermore, the additional waterproof membrane covers the additional insulation layer and overlaps the outside of the second upturned waterproof membrane.

[0031] Detailed implementation method.

[0032] The embodiments of this utility model will be further described in detail below through examples and with reference to the accompanying drawings.

[0033] like Figure 1 As shown, this invention provides a connection structure for the rooftop exterior door and roof insulation and waterproofing system of ultra-low energy consumption buildings, including a rooftop exterior door threshold, a building roof slab, and a vapor barrier membrane. The vapor barrier membrane is fully adhered to the building roof slab, and when it encounters the rooftop exterior door threshold or other roof walls, it is turned up 200mm above the finished roof surface. Simultaneously with the vapor barrier membrane installation, the roof insulation layer is laid. The roof insulation layer is laid in double layers with staggered joints and is constructed using a dry method. The roof insulation layer construction is divided into sections according to the construction progress. After the insulation layer construction in the same area is completed, the first layer of waterproof membrane is immediately laid. The first layer of waterproof membrane is fully adhered to the roof insulation layer, and when it encounters the rooftop exterior door threshold or other roof walls, it is turned up to cover the bottom layer of vapor barrier membrane and terminated on the rooftop exterior door threshold or other roof walls.

[0034] After the roof insulation layer and the first layer of waterproof membrane are completed, the upper insulation layer is installed. A 200-300mm space should be reserved at the threshold of the roof door for the upper insulation layer. The roof door is then installed. The upper insulation layer is dry-bonded to the threshold of the roof door or other roof walls. Thermal bridge anchors can be used for fixation as needed. After the upper insulation layer is completed, the first layer of waterproof membrane is fully applied to the outside of the upper insulation layer. One end of the first layer of waterproof membrane covers the top of the upper insulation layer, and the other end covers the upper insulation layer. The end is then terminated on the first layer of waterproof membrane, with an overlap width of not less than 100mm.

[0035] After the first layer of upturned waterproof membrane is installed, the second layer of waterproof membrane is installed on the roof. The second layer of waterproof membrane is fully adhered to the top of the first layer of waterproof membrane, and the horizontal end is covered to cover the joint between the first layer of upturned waterproof membrane and the first layer of waterproof membrane. It is then adhered to the overlapping surface of the first layer of upturned waterproof membrane.

[0036] After the second layer of waterproof membrane is installed, the second layer of upturned waterproof membrane is installed. The second layer of upturned waterproof membrane is fully adhered to the outside of the first layer of upturned waterproof membrane. One end of the second layer of waterproof membrane is attached to the outer door threshold or other roof wall of the roof layer, and the other end covers the first layer of upturned waterproof membrane. The end is then terminated on the second layer of waterproof membrane, and the termination position should completely cover the overlapping surface of the first and second layers of waterproof membrane.

[0037] The rooftop exterior door is installed externally, with a continuous heat-insulating strip used to fix the bottom edge. One end of the EPDM waterproof vapor barrier membrane is pasted to the inside of the rooftop exterior door threshold, and the other end is pasted to the rooftop exterior door frame. One end of the EPDM waterproof vapor permeable membrane is pasted to the rooftop exterior door frame, and the other end is wrapped with a continuous heat-insulating strip before being pasted to the outside of the second layer of upturned waterproof membrane.

[0038] After the roof-level exterior door is installed, an additional insulation layer should be installed. The thickness of the additional insulation layer should be consistent with that of the upturned insulation layer, and the gap between the continuous thermal insulation strip and the upturned insulation layer should be completely filled. At the same time, it should cover the roof-level exterior door frame as much as possible.

[0039] After the additional insulation layer is completed, the additional waterproof membrane is used to completely cover the additional insulation layer, with one end overlapping the outer door frame of the roof and the other end overlapping the outside of the second layer of upturned waterproof membrane.

[0040] The above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
