Description

Technical Field

[0001] This invention relates to the field of building energy conservation, and in particular to a structure for thermal break bridges suitable for roof structures of ultra-low energy consumption buildings. Background Technology

[0002] Ultra-low energy buildings have developed rapidly in recent years and represent an important direction for low-carbon and energy-saving building development. The number of design projects is gradually increasing, and the development prospects are very broad. At present, in the ultra-low energy building technology system, the roof often inevitably needs to be equipped with various equipment foundations, structural foundations, and inverted beams, which creates a large number of potential cold bridge hazards. The design of this part is still imperfect and lacks relevant structural measures.

[0003] The main feature of ultra-low energy buildings is the absence of thermal bridges. The absence of thermal bridges in the roof is closely related to the roof structure, roof waterproofing, roof insulation, and airtightness protection of ultra-low energy roofs. The continuity of thermal insulation in the roof of ultra-low energy buildings is the key to roof energy-saving design, which places high demands on the thermal break construction nodes.

[0004] Existing ultra-low energy building technologies include roofing technologies. Among them, utility model patent CN113638556A discloses a heavy equipment roofing node for a passive ultra-low energy building, comprising an equipment roof foundation, an insulation layer, and an embedded plate arranged from bottom to top. The equipment roof foundation includes a structural roof and an equipment foundation. Multiple mounting components are provided on the equipment foundation, embedded in the insulation layer. Each mounting component includes a connecting block, a heat-insulating block, and a connecting rod. The connecting block is connected to the equipment foundation, the heat-insulating block is located inside the connecting block, and one end of the connecting rod is detachably connected to the heat-insulating block, while the other end penetrates through the insulation layer and the embedded plate. This invention connects the equipment foundation to the roof structure by using mounting components with heat-insulating blocks, avoiding the thermal bridging effect caused by direct anchor bolt connections, thereby achieving a thermal insulation effect.

[0005] Existing technologies can meet the equipment installation requirements of ultra-low energy consumption building roofs to a certain extent, but their thermal insulation effect and durability still need to be improved. Existing technologies cannot adapt to various types of roof structure thermal break constructions and cannot provide effective on-site installation guidance.

[0006] The present invention provides a structure for thermal break bridges suitable for roof structures of ultra-low energy consumption buildings, which can effectively solve the above problems, ensure continuous thermal insulation of the building roof, durability of the thermal break bridge structure, continuous airtightness, and facilitate on-site construction. Summary of the Invention

[0007] In view of the problems in the background technology, and in order to solve the problems of thermal insulation performance, air tightness, waterproof sealing performance and construction and installation feasibility of the roof structure of ultra-low energy consumption buildings, improve building performance and shorten the construction period, this invention proposes a thermal break structure suitable for the roof structure of ultra-low energy consumption buildings.

[0008] A structure suitable for thermal break roofs in ultra-low energy consumption buildings is characterized by: comprising a roof structure floor slab 14 and a roof structure 15 disposed on the roof structure floor slab 14; the roof structure floor slab 14 is sequentially provided with a roof underlayment 13, a roof leveling layer 12, a vapor barrier 11, a roof insulation layer 10, a roof waterproofing layer 9, and a roof finishing layer 8; the roof underlayment 13, the roof leveling layer 12, and the roof insulation layer 10 are interrupted at the roof structure 15; the vapor barrier 11 is disposed along the outer side of the roof structure 15; this structure also... The structure includes a high-density thermal break material 1, an additional waterproof layer 2, a thermal insulation pad 3, a mortar leveling layer 4, a wear-resistant coating surface layer 5, pre-embedded mounting bolts 6, silicone building sealant 7, and crack-resistant mesh fabric 16. The high-density thermal break material 1 is installed on the outside of the roof structure 15. The thermal insulation pad 3 is installed on the upper side of the roof structure 15. The additional waterproof layer 2 is installed on the outside of the high-density thermal break material 1 and the thermal insulation pad 3. The mortar leveling layer 4 is installed on the outside of the additional waterproof layer 2. The wear-resistant coating surface layer 16... The layer is set on the outside of the mortar leveling layer 4. The pre-embedded installation bolts 6 pass through the wear-resistant coating surface layer 5, the mortar leveling layer 4, the heat insulation pad 3, and the additional waterproof layer 2. The pre-embedded installation bolts 6 extend into the roof structure 15. The silicone building sealant 7 is between the pre-embedded installation bolts 6 and the mortar leveling layer 4. The crack-resistant mesh 16 is located in the mortar leveling layer 4. The wear-resistant coating surface layer 5 is connected to the roof construction layer 8 at the bottom. Furthermore, the roof structure floor slab 14 is selected as a reinforced concrete cast-in-place floor slab, pre-... The roof structure 15 is selected from either a reinforced concrete composite floor slab or a steel frame floor slab. The roof structure 15 is selected from either a reinforced concrete structure or a reinforced concrete structure. The roof structure 15 and the roof structure floor slab 14 are connected by either prefabrication or on-site construction. Furthermore, the high-density thermal insulation layer thermal break material 1 is selected from either a high-density graphite polystyrene board or a water-repellent rock wool insulation board, with a thickness of not less than 100mm. Furthermore, the thermal insulation pad 3 is a high-strength polyurethane thermal insulation pad with a thickness of not less than 100mm.

[0009] Furthermore, the vapor barrier layer 11 is tightly and continuously laid along the roof leveling layer 12 and the outer side of the roof structure 15. The roof waterproof layer 9 is turned up on the outer side of the roof structure 15, with an upturn height of not less than 150mm. The upturned position of the roof waterproof layer 9 is tightly connected to the vapor barrier layer 11. The vapor barrier layer 11 is made of either alkali-resistant aluminum foil surface fiberglass-reinforced self-adhesive modified bitumen vapor barrier roll or alkali-resistant aluminum foil reinforced fiberglass-reinforced modified bitumen vapor barrier roll.

[0010] Furthermore, the additional waterproof layer 2 is a 4mm thick SBS waterproof membrane, and the additional waterproof layer 2 is laid with a horizontal length of not less than 200mm and is connected vertically to the roof waterproof layer 9.

[0011] Furthermore, the crack-resistant mesh 16 is placed at the inside and outside corners of the mortar leveling layer 4, with a laying length of not less than 150mm in each direction.

[0012] Furthermore, the pre-embedded mounting bolt 6 has a top protrusion of the wear-resistant coating layer 5, and silicone building sealant 7 is installed at the position where the pre-embedded mounting bolt 6 passes through the mortar leveling layer 4.

[0013] Furthermore, the pre-embedded mounting bolts and silicone building sealant 7 are used in roof structures where equipment needs to be installed, but not in other structural thermal break constructions.

[0014] Furthermore, both the heat insulation pad 3 and the high-density thermal insulation layer thermal break material 1 are manufactured in the factory according to the design dimensions to form standardized prefabricated products.

[0015] Compared with existing methods, the beneficial effects achieved by this invention are as follows:

[0016] The use of thermal insulation pads 3 and high-density thermal insulation thermal break material 1 effectively blocks thermal bridges at the roof structure locations, improving the thermal break performance of the overall roof structure.

[0017] Since the thermal insulation pad 3 and the high-density thermal insulation layer thermal break material 1 can be prefabricated and mass-produced in the factory, the construction efficiency of the thermal break structure at the roof structure on the building site is greatly improved, and the construction accuracy and quality are improved.

[0018] The addition of an additional waterproof layer 2, which extends horizontally, improves the waterproofing performance at the location of the thermal break in the roof structure.

[0019] Because the vapor barrier 11 is continuously laid on the outside of the roof structure 15 and connected to the upturned roof waterproof layer 9, the integrity of the airtightness of the ultra-low energy consumption roof is ensured, and the waterproofness and durability are enhanced.

[0020] The use of wear-resistant coating layer 5 enhances the overall weather resistance and durability of the structural broken bridge, and also improves the aesthetics of the finished product.

[0021] This invention, through the design of high-performance thermal break and waterproof structure, greatly improves the rationality, durability, thermal break and waterproof performance of building roof structure, thereby enhancing building quality. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. The specific embodiments described herein are only for explaining this invention and are not intended to limit this invention.

[0028] Specific example 1:

[0029] Reference Figure 1 This utility model provides a structure for a thermal break bridge suitable for roof structures of ultra-low energy consumption buildings.

[0030] The roof structure floor slab 14 is a precast concrete composite floor slab, and the roof structure 15 is a reinforced concrete structure, which is a foundation for roof heating and ventilation fan equipment.

[0031] The aforementioned heat insulation pad 3 is a 150mm thick high-strength polyurethane heat insulation pad, which is prefabricated in the factory to form a customized product.

[0032] The vapor barrier layer 11 is an alkali-resistant aluminum foil-faced fiberglass-reinforced self-adhesive modified bitumen vapor barrier roll.

[0033] The high-density thermal insulation layer thermal break material 1 is a 200mm thick high-density graphite polystyrene board, which is prefabricated in the factory to form a customized product.

[0034] At the construction site, the roof structure floor slab 14 and the roof structure 15 are constructed first. The reinforcement in the roof structure 15 extends into the roof structure floor slab 14 to form a firm fixation. The pre-embedded installation bolts 6 are then inserted into the roof structure 15 for secure fixing.

[0035] After the concrete structure has been cured, the roof subfloor 13, roof leveling layer 12, and vapor barrier 11 are constructed sequentially on the roof structural floor slab 14.

[0036] The roof subbase 13 and the roof leveling layer 12 are disconnected at the point where they meet the roof structure 15. The vapor barrier 11 is laid along the roof leveling layer 12 to the point where it turns up and is continuously laid to completely cover the roof structure 15.

[0037] Subsequently, the roof insulation layer 10 is constructed. The roof insulation layer 10 is made of double-layer graphite polystyrene board laid in a staggered manner up to the vapor barrier layer 11 and the vapor barrier layer 11 is pressed tightly.

[0038] The roof waterproofing layer 9 uses 4+3 thick SBS waterproof membrane, which is tightly laid along the roof insulation layer 10 and extends up 200mm to the vapor barrier layer 11, where it is tightly laid and connected.

[0039] The high-density thermal insulation layer thermal break material 1 and the thermal insulation pad 3 are respectively pasted to the side and top surface of the roof structure 15. When the thermal insulation pad 3 is laid, it presses down on the high-density thermal insulation layer thermal break material 1 and they are bonded to each other.

[0040] The additional waterproof layer 2 is laid on the outside of the high density thermal insulation layer thermal break material 1 and the heat insulation pad 3, and extends 250mm in length on the horizontal roof surface to be tightly bonded to the roof waterproof layer 9.

[0041] Apply mortar leveling layer 4 to the outside of the additional waterproof layer 2, and press anti-crack mesh 16 into the inside and outside corners of the mortar leveling layer 4.

[0042] Apply mortar leveling layer 4 to the position of the pre-embedded installation bolt 6, and seal it around the bolt with silicone building sealant 7.

[0043] Finally, the roof construction layer 8 is implemented, which is covered by roof tiles. The wear-resistant coating layer 5 is applied to cover the outside of the roof structure thermal break mortar leveling layer 4, and the roof construction layer 8 is covered at the bottom of the roof.

[0050] At the construction site, the roof structure 15 and the roof structure floor slab 14 are constructed together to form a complete roof structure system, and then maintenance is carried out.

[0051] The surface of the roof structure after curing is cleaned and then the roof subbase 13, roof leveling layer 12, and vapor barrier 11 are constructed sequentially. The vapor barrier 11 is laid along the roof leveling layer 12, extending up to the roof structure 15 and ensuring continuous and complete coverage of the roof structure 15. The roof insulation layer 10 is made of double-layer extruded polystyrene board, laid with staggered joints up to the upturned vapor barrier 11 and pressed firmly. The roof waterproofing layer 9 uses 4+3mm thick SBS waterproof membrane, tightly laid along the roof insulation layer 10 up to the upturned vapor barrier 11, extending to the top of the roof structure 15 and tightly connected to the vapor barrier 11.

[0052] The high-density thermal insulation layer thermal break material 1 and the thermal insulation pad 3 are respectively pasted to the side and top surface of the roof structure 15. When the thermal insulation pad 3 is laid, it presses down on the high-density thermal insulation layer thermal break material 1 and they are bonded to each other.

[0053] The additional waterproof layer 2 is laid on the outside of the high-density thermal insulation layer thermal break material 1 and the heat insulation pad 3, and extends 200mm in length on the horizontal roof surface to be tightly bonded to the roof waterproof layer 9. A mortar leveling layer 4 is applied to the outside of the additional waterproof layer 2, and crack-resistant mesh 16 is pressed into the mortar leveling layer 4.

[0054] Finally, the roof construction layer 8 is implemented, using slate-faced environmentally friendly modified bitumen waterproof membrane, which is continuously laid along the outer side of the topmost layer of the roof and the mortar leveling layer 4 of the roof thermal break structure to ensure complete coverage.

[0055] The above specific embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit of the technical solution of the present invention and the structure that protects the broken bridge of the building roof structure, effectively ensuring the thermal insulation and energy-saving performance, durability performance and the protection of the roof system from external rainwater erosion of the ultra-low energy consumption building roof.
