Description

Technical Field

[0001] This invention relates to the field of building waterproofing and thermal insulation technology, and in particular to a spliced ​​thermal insulation and waterproofing building membrane. Background Technology

[0002] Waterproof membranes are indispensable waterproofing materials in building construction. They are mainly used on building roofs, walls, basements, and other parts to prevent rainwater and groundwater from seeping in. At the same time, some waterproof membranes also have thermal insulation functions, which can reduce building energy consumption and improve the comfort of building use.

[0003] However, existing building waterproof membranes have many shortcomings in use and cannot meet the multiple needs of modern buildings for waterproofing, insulation, and ease of construction. Traditional waterproof membranes are mostly spliced ​​by overlapping, with the overlaps only fixed by adhesive, resulting in poor sealing performance. After long-term use, due to factors such as temperature changes, rainwater erosion, and building settlement, the overlaps are prone to cracking and delamination, leading to rainwater infiltration, affecting the structural safety and service life of the building. Poor splicing sealing and prominent leakage risks are also issues. Therefore, a spliced ​​thermal insulation waterproof membrane is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a spliced ​​thermal insulation and waterproof building membrane in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a first roll body and a second roll body, wherein the first roll body and the second roll body are stacked sequentially from top to bottom and are provided with a waterproof surface layer, a thermal insulation layer, a moisture-proof buffer layer and an adhesive bottom layer, and a splicing component is provided at the connection point on one side of the first roll body and the second roll body.

[0006] The splicing assembly includes a concave splicing portion on one side of the first roll body and a convex splicing portion on one side of the second roll body. The convex and concave splicing portions are sized to match, and both ends are fixedly connected to an integrally formed reinforcing wing plate. A groove is formed at the upper end of the concave splicing portion, and two sealing protrusions are symmetrically installed above the groove on the surface of the concave splicing portion. A positioning boss, matching the size of the groove, is fixedly installed at the bottom of the convex splicing portion. Fastening bolts are threaded to the four corners inside the convex splicing portion, with the ends of the four fastening bolts connected to the inside of the concave splicing portion. Sealant is applied to the connection between the concave and convex splicing portions. The groove and the positioning boss are positioned opposite each other, and both the groove and the positioning boss... The design is trapezoidal, with four equidistant positioning posts fixedly installed inside the groove. The positioning boss has four positioning holes matching the size of the positioning posts. Two sealing grooves are symmetrically opened on both sides of the positioning boss at the bottom of the convex splicing part. Waterproof sealing strips are fixedly connected inside the two sealing grooves. The sealing strip is embedded inside the sealing groove and fits against the waterproof sealing strip. Installation grooves of the same size are opened at the four corners of both the convex and concave splicing parts. The fastening bolts are threaded into the installation grooves. Metal reinforcing edges are fixedly installed on the front and rear sides of the outer walls of both the convex and concave splicing parts. The thickness of the metal reinforcing edges is the same as that of the roll material body, and the metal reinforcing edges are made of thin stainless steel.

[0007] In practical applications, by setting up a double sealing structure (sealing strip and waterproof sealing convex strip + sealant) and fastening bolts in conjunction with the trapezoidal splicing surface, the splicing contact area is increased, effectively blocking rainwater and water vapor penetration, completely solving the problems of poor sealing and easy leakage of existing roll material overlaps, and improving waterproof reliability. At the same time, positioning posts are set in the groove and locked with the positioning holes at the bottom of the positioning convex platform to form a mechanical locking structure, which is conducive to achieving double locking and fixing when splicing two roll materials while improving their sealing effect.

[0008] Furthermore, the thermal insulation layer includes an inner thermal insulation core material and an outer thermal insulation coating. The lower surface of the adhesive substrate is covered with a protective film. A tear-off tab is provided at one corner of the edge of the protective film. The thermal insulation layer is fixedly connected to the waterproof surface layer and the moisture-proof buffer layer by adhesive. A number of vent holes of the same size are provided between the thermal insulation layer and the moisture-proof buffer layer. A conical protective cap is provided at the upper end of the vent hole near the thermal insulation layer. A one-way vent valve is provided at the lower end of the vent hole near the moisture-proof buffer layer. The one-way vent valve is made of rubber and is flush with the lower surface of the moisture-proof buffer layer. The end of the conical protective cap is in contact with the bottom of the waterproof surface layer.

[0009] In practical applications, the one-way vent valve allows water vapor to be discharged only from the thermal insulation layer toward the moisture-proof buffer layer. The discharged water vapor can be dispersed along the gap between the lower surface of the moisture-proof buffer layer and the upper surface of the bonding substrate. This prevents rainwater and water vapor from penetrating back into the thermal insulation layer without affecting the bonding effect between the bonding substrate and the building base. At the same time, it prevents the vent holes from becoming blocked, effectively avoiding blockage and rainwater penetration.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By setting up splicing components and adapting the convex and concave splicing parts, quick alignment can be achieved during splicing without complex positioning, improving construction efficiency. The splice joint is equipped with a double sealing structure (sealing strip and waterproof sealing convex strip + sealant), and fastening bolts cooperate with the trapezoidal splicing surface to increase the splicing contact area, effectively blocking rainwater and water vapor penetration, completely solving the problems of poor sealing and easy leakage of existing roll material overlaps, and improving waterproof reliability. At the same time, positioning posts are set in the groove and engage with the positioning holes at the bottom of the positioning boss to form a mechanical locking structure, which is conducive to achieving double locking and fixing when splicing two rolls of material, while improving their sealing effect. Compared with the problem of poor sealing caused by traditional bonding with adhesive alone, reinforcing wing plates are added to the ends of the convex and concave splicing parts. The reinforcing wing plates are integrally formed with the roll body, further improving the mechanical strength of the splice joint, resisting the settlement of the base layer, thermal expansion and contraction, and external pulling force, avoiding misalignment and cracking at the splice joint, making splicing convenient and sealingly strong.

[0012] 2. Ventilation holes, conical protective caps, and one-way ventilation valves are installed inside the roll material. The protective caps are integrally formed with the ventilation holes. The conical structure prevents dust and debris from entering the ventilation holes. A one-way ventilation valve is installed at the lower end of the ventilation hole near the moisture-proof buffer layer. The one-way ventilation valve is made of rubber, and its top interface is tightly connected to the bottom of the ventilation hole. The outlet of the one-way ventilation valve is located on the lower surface of the moisture-proof buffer layer and does not penetrate the bonding substrate. It is only flush with the lower surface of the moisture-proof buffer layer, ensuring that the one-way ventilation valve only allows water vapor to be discharged from the thermal insulation layer towards the moisture-proof buffer layer. The discharged water vapor can be dispersed along the gap between the lower surface of the moisture-proof buffer layer and the upper surface of the bonding substrate. This not only prevents rainwater and water vapor from back-permeating into the thermal insulation layer, but also does not affect the bonding effect between the bonding substrate and the building base layer. At the same time, it prevents the ventilation holes from being blocked, effectively avoiding blockage and rainwater penetration.

[0013] 3. The thermal insulation layer employs a composite structure. The inner insulation core material can be flexibly selected in terms of material and thickness according to the insulation requirements of different regions and building parts. The outer ceramic insulation coating effectively reflects solar radiation heat, achieving a dual effect of thermal insulation and heat preservation. It is suitable for different climates, including extremely cold and hot regions, and for various building parts such as roofs, walls, and basements, offering strong versatility. The adhesive bottom layer features a peelable protective film, eliminating the need for additional adhesive during construction; simply peel off the protective film to apply the insulation directly, simplifying the construction process, reducing construction difficulty, and improving construction efficiency. When the membrane is damaged, the damaged area can be replaced individually without large-scale removal, reducing maintenance costs and minimizing the impact on normal building use. The waterproof surface layer uses modified asphalt material, combined with a wear-resistant and anti-aging coating, enhancing waterproofing, wear resistance, and UV resistance. The moisture-proof buffer layer effectively blocks water vapor penetration, preventing the insulation layer from becoming damp and moldy. All layers are connected using a high-temperature resistant adhesive, ensuring structural stability, adaptability to extreme climatic conditions, extending the membrane's service life, and reducing building maintenance costs.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Reference Figure 1-6 A spliced ​​thermal insulation waterproof membrane for buildings includes a first membrane body 1 and a second membrane body 2. The first membrane body 1 and the second membrane body 2 are stacked from top to bottom and are provided with a waterproof surface layer 14, a thermal insulation layer 13, a moisture-proof buffer layer 12 and an adhesive bottom layer 11. A splicing component 3 is provided at the connection point on one side of the first membrane body 1 and the second membrane body 2.

[0024] The splicing assembly 3 includes a concave splicing portion 31 on one side of the first roll body 1 and a convex splicing portion 32 on one side of the second roll body 2. The convex splicing portion 32 and the concave splicing portion 31 are sized to match, and both the convex splicing portion 32 and the concave splicing portion 31 are fixedly connected to an integrally formed reinforcing wing plate 33 at their ends. The upper end of the concave splicing portion 31 has a groove 37, and two sealing protrusions 38 are symmetrically installed on the surface of the concave splicing portion 31 above the groove 37. The bottom of the convex splicing portion 32 is fixedly installed with a positioning boss 39 that matches the size of the groove 37. Fastening bolts 35 are threaded to the four corners inside the convex splicing portion 32, and the ends of the four fastening bolts 35 are connected to the inside of the concave splicing portion 31. The connection between the concave splicing portion 31 and the convex splicing portion 32 is coated with sealant 36. The groove 37 and the positioning boss 39 are positioned opposite each other, and both the groove 37 and the positioning boss 39 are... The design is trapezoidal, with four equidistant positioning posts 371 fixedly installed inside the groove 37. The positioning boss 39 has four positioning holes 391 that match the size of the positioning posts 371. The bottom of the convex splicing part 32 has two symmetrical sealing grooves 392 on both sides of the positioning boss 39. Waterproof sealing strips 393 are fixedly attached inside the two sealing grooves 392. The sealing strip 38 is embedded in the sealing groove 392 and is attached to the waterproof sealing strip 393. The four corners of the convex splicing part 32 and the concave splicing part 31 have mounting grooves 351 of the same size. The fastening bolts 35 are threaded into the mounting grooves 351. Metal reinforcing edges 34 are fixedly installed on the front and rear sides of the outer walls of the convex splicing part 32 and the concave splicing part 31. The thickness of the metal reinforcing edges 34 is the same as that of the roll material body, and the metal reinforcing edges 34 are made of thin stainless steel.

[0025] In practical applications, when splicing two rolls of material, the positioning boss 39 at the bottom of the convex splicing part 32 on one side of the second roll body 2 is first aligned with the groove 37 at the upper end of the concave splicing part 31 on one side of the first roll body 1. After the positioning boss 39 and the groove 37 are aligned, the positioning post 371 set in the groove 37 is inserted and limited by the positioning hole 391 at the bottom of the positioning boss 39, which initially improves the tightness of the connection between the two rolls. After the convex splicing part 32 and the concave splicing part 31 are aligned, the two sealing protrusions 38 at the upper end of the concave splicing part 31 are embedded and engaged with the two sealing grooves 392 at the bottom of the convex splicing part 32, so that the sealing protrusions 38 squeeze the waterproof sealing strip 393 in the sealing groove 392, thus securing the two rolls together. After initial sealing, sealant 36 is sprayed at the joint between the convex splice 32 and the concave splice 31 to further improve the sealing effect. Reinforcing wing plates 33 are added to the ends of the convex splice 32 and the concave splice 31. The reinforcing wing plates 33 are integrally formed with the roll material body. After splicing, the reinforcing wing plates 33 of adjacent roll materials are fixedly connected by fastening bolts 35 to further improve the mechanical strength of the splice, resist the settlement of the base layer, thermal expansion and contraction and external force pulling, and avoid misalignment and cracking at the splice. At the same time, a double sealing structure (sealing convex strip 38 and waterproof sealing strip 393 + sealant 36) is set up. With the trapezoidal splice surface, the splice contact area is increased, effectively blocking rainwater and water vapor penetration, and completely solving the problems of poor sealing and easy leakage of existing roll material overlaps.

[0026] When laying waterproof membrane, the operator first cleans the surface of the building substrate to ensure that the substrate is flat, dry, and free of debris. If there are cracks or depressions in the substrate, they need to be repaired and leveled in advance. Peel off the tear ears 151 of the protective film 15 at the bottom of the membrane body, and peel off the protective film 15 as a whole. Align the adhesive underlayer 11 with the substrate laying position, and melt the hot-melt modified asphalt adhesive layer by heating to bond it tightly to the substrate. During the laying process, ensure that the membrane is flat, free of air bubbles and wrinkles. Embed the convex splice part 32 of the adjacent membrane body into the concave splice part 31, so that the trapezoidal positioning boss 39 and the groove 37 are engaged. Simultaneously, the sealing protrusion 38 and the waterproof sealing strip 393 in the sealing groove 392 are precisely fitted to ensure the splicing is aligned and sealed. Then, polyurethane sealant 36 is filled into the gap between the sealing groove 392 and the sealing protrusion 38 and compacted to form a double sealing structure. After the roll material is laid, the surface of the roll material is compacted to ensure that the roll material is tightly bonded to the base layer and adjacent roll materials. The splicing is inspected, and if there are gaps, sealant 36 is added in time to ensure reliable sealing. If the roll material is partially damaged, only the damaged part needs to be cut, a new roll material segment needs to be replaced, and the roll material needs to be re-sealed. There is no need for large-area removal.

[0027] A plurality of through-holes 391 are provided along the length direction on the positioning boss 39 at the bottom of the convex splicing part 32. Positioning posts 371 corresponding to the positioning holes 391 are provided at the bottom of the groove 37 of the concave splicing part 31. The positioning posts 371 and the positioning holes 391 are interference-fitted. During splicing, the positioning posts 371 are embedded into the positioning holes 391, forming a mechanical locking structure. Simultaneously, reinforcing wing plates 33 are added to the ends of the convex splicing part 32 and the concave splicing part 31. The reinforcing wing plates 33 are integrally formed with the roll body. After splicing, the reinforcing wing plates 33 of adjacent rolls are fixedly connected by fastening bolts 35. Furthermore, metal reinforcing edges 34 are added to both sides of the roll body (the outer sides of the convex splicing part 32 and the concave splicing part 31). The metal reinforcing edges 34 are thin. Made of stainless steel, it is fixedly connected to the roll material body by a high-temperature resistant adhesive, and the thickness of the metal reinforcing edge 34 is the same as the thickness of the roll material body, which does not affect splicing and laying. The metal reinforcing edge 34 can enhance the mechanical strength of the roll material edge, avoid damage and curling during construction, handling and laying, and improve the waterproof performance of the roll material edge, extending its service life. The groove 37, positioning boss 39, sealing boss 38, sealing groove 392 and waterproof sealing strip 393 are all trapezoidal in shape, which facilitates interlocking and splicing without position conflict. The applicant has taken this into consideration. The waterproof sealing strip 393 is made of butyl rubber, and the outer wall of the fastening bolt 35 is coated with a waterproof coating, so that the convex splice part 32 and the concave splice part 31 are connected tightly.

[0028] Furthermore, refer to Figure 1-6 The thermal insulation layer 13 includes an inner thermal insulation core material 132 and an outer thermal insulation coating 131. The lower surface of the adhesive bottom layer 11 is covered with a protective film 15. A tear-off ear 151 is provided at one corner of the edge of the protective film 15. The connection between the thermal insulation layer 13 and the waterproof surface layer 14 and the moisture-proof buffer layer 12 is fixedly connected by adhesive. A number of vent holes 41 of the same size are opened between the thermal insulation layer 13 and the moisture-proof buffer layer 12. A conical protective cap 4 is provided on the upper end of the vent hole 41 near the thermal insulation layer 13. A one-way vent valve 42 is provided on the lower end of the vent hole 41 near the moisture-proof buffer layer 12. The one-way vent valve 42 is made of rubber and is flush with the lower surface of the moisture-proof buffer layer 12. The end of the conical protective cap 4 is in contact with the bottom of the waterproof surface layer 14.

[0029] In practical applications, ventilation holes 41 are provided inside the roll material between the thermal insulation layer 13 and the moisture-proof buffer layer 12. Each ventilation hole 41 has a conical protective cap 4 at its upper end and a one-way ventilation valve 42 at its lower end. The top interface of the one-way ventilation valve 42 is sealed to the bottom of the ventilation hole 41, and its outlet is located on the lower surface of the moisture-proof buffer layer 12, flush with the lower surface of the moisture-proof buffer layer 12 and not penetrating the adhesive underlayer 11. This ensures that the one-way ventilation valve 42 only allows moisture to escape from the thermal insulation layer. Layer 13 is discharged towards the moisture-proof buffer layer 12. The discharged water vapor can be dispersed along the gap between the lower surface of the moisture-proof buffer layer 12 and the upper surface of the bonding substrate 11. This not only prevents rainwater and water vapor from penetrating back into the thermal insulation layer 13, but also does not affect the bonding effect between the bonding substrate 11 and the building base. At the same time, it prevents the vent hole 41 from being blocked. The mechanical protection structure of the vent hole 41 is optimized. The conical protective cap 4 is integrally formed with the vent hole 41 and is set at the upper end of the vent hole 41, that is, on the side close to the thermal insulation layer 13.

[0030] The thermal insulation layer 13 is a composite structure, including an inner thermal insulation core material 132 and an outer thermal insulation coating 131. The inner thermal insulation core material 132 can be made of extruded polystyrene board, rock wool board, or polyurethane foam board of different thicknesses to meet the insulation requirements of different regions and building parts. The outer thermal insulation coating 131 uses a ceramic thermal insulation coating, which can effectively reflect solar radiation heat, improve the insulation effect, and achieve flexible adaptation of thermal insulation performance. Extruded polystyrene board has good thermal insulation effect and low water absorption, making it suitable for roof waterproofing and insulation. Rock wool board has excellent fire resistance and high temperature resistance, making it suitable for industrial buildings or scenarios with high fire protection requirements. Polyurethane foam board has high thermal insulation efficiency and is lightweight, making it suitable for wall waterproofing and insulation. It can be flexibly selected according to actual insulation needs and adapted to different regional climate conditions. The lower surface of the bonding substrate 11 is covered with a peelable protective film 15. During construction, simply peel off the protective film 15, and the roll material can be directly laid on the building substrate surface without additional adhesive, simplifying the construction process. The construction process is streamlined to improve efficiency. The bonding layer 11 uses a hot-melt modified asphalt adhesive layer with high bonding strength, ensuring a tight bond between the membrane and the substrate and preventing detachment. The waterproof surface layer 14 uses a modified asphalt waterproof layer, which has excellent waterproof performance, high and low temperature resistance, and anti-aging properties, effectively blocking rainwater and groundwater penetration. The upper surface of the waterproof surface layer 14 has a wear-resistant and anti-aging coating made of acrylic anti-aging paint, which improves the wear resistance and UV resistance of the membrane surface, extending the membrane's service life and making it suitable for outdoor exposure. The moisture-proof buffer layer 12 uses a polyethylene moisture-proof film, which has excellent moisture-proof and water-resistant properties, effectively preventing moisture from penetrating into the thermal insulation layer 13, preventing the insulation layer from becoming damp and moldy, and ensuring long-term stable thermal insulation performance. An adhesive layer is provided between the moisture-proof buffer layer 12, the thermal insulation layer 13, and the bonding layer 11. The adhesive layer uses a high-temperature and water-resistant adhesive to ensure a tight connection between the layers and prevent delamination.
