Description

Technical Field

[0001] The present invention relates to the technical field of roof tiles, and in particular to a factory building waterproofing and metal plate integrated roof tile and a construction method. Background Art

[0002] Roof tiles are lightweight roofing materials constructed from a metal substrate (such as galvanized steel or aluminum-zinc alloy) coated with a colored anti-corrosion coating and then roll-formed. Their wavy and trapezoidal cross-sections enhance structural strength and optimize drainage. They are typically installed horizontally, from the eaves to the ridge. Individual tiles extend across the width of the roof, eliminating the potential for leakage from longitudinal joints. Adjacent tiles are overlapped, and sealant is applied at these joints to enhance waterproofing.

[0003] Currently, the following problems exist in the installation and use of roof tiles: First, when relying on the vertical fixing method of self-tapping screws, when the roof is subjected to wind loads, the screws can only resist the pull-out force in the vertical direction, but cannot effectively suppress the horizontal slippage of the roof tiles along the purlin direction and the warping deformation at the overlap. Secondly, in the longitudinal overlap, there is only a physical overlap of wave crest coverage and a filling of sealant, and a mechanical interlocking structure is not formed. As a result, the overlap edge is prone to high-frequency vibration under the action of wind pressure. Long-term accumulation will cause the screw holes to expand and the sealant to fatigue and crack, eventually causing local tiles to loosen or even a chain reaction. Furthermore, the sealant will harden and crack over time, especially since the metal tiles and the sealant have different degrees of thermal expansion and contraction. After repeated expansion and contraction, the sealant and the metal tiles are prone to separation.

[0004] Therefore, the vertical fixing method of self-tapping screws cannot effectively suppress the horizontal slippage and warping deformation of roof tiles, the aging and cracking of sealants and the difference in thermal expansion and contraction cause debonding, which affects the waterproofness, wind resistance and durability of the roof. These are technical problems that need to be solved by technical personnel in this field. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides a factory waterproofing and metal plate integrated roof tile and a construction method to solve the above-mentioned technical problems.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides the following technical solution: a factory waterproof and metal plate integrated roof tile, including a serrated roof tile and an inverted concave gusset plate, and the surface of the roof tile and the gusset plate are covered with a waterproof membrane.

[0007] The crests on the left and right ends of the roof tiles are equipped with interlocking plates for mutual interlocking. The gusset plates are buckled and covered at the overlap of adjacent roof tiles, and a reinforcement mechanism is provided inside the gusset plates.

[0008] The reinforcement mechanism includes a plurality of screws installed to rotate uniformly along the top of the gusset plate cover. The lower end of the screw passes through the gusset plate. The upper part of the screw is provided with a positive thread section, the lower part is provided with a negative thread section and the bottom end is provided with a self-tapping screw section. The positive thread section is engaged with a screw disk, and a pair of pull rods are hinged on the screw disk. The other end of the pull rod is hinged to the inner side of the gusset plate side wing, the negative thread section is engaged with a screw plate, and a pressure plate is provided on the screw plate.

[0009] During laying, the roof tiles are overlapped by interlocking plates, and the horizontal joints are sealed by a waterproof membrane. After the gusset plates are buckled on the overlaps, the screws are rotated in sequence so that the self-tapping screw sections pass through the interlocking plates and are fixed to the purlins. The positive thread section drives the screw disc upward so that the pull rod pulls the gusset plate side wings inward to press the roof tiles. The negative thread section drives the screw plate downward so that the pressure plate presses and locks the interlocking plates and purlins. At this time, the laterally adjacent pressure plates form an overlapping limit section to constrain lateral displacement.

[0010] As a preferred solution, a pair of sliding rods are fixedly installed at the lower end of the screw disk, and a sliding sleeve is fixedly installed at the lower end of the screw plate, which slides in correspondence with the sliding rods. The lower end of the sliding rod slides through the screw plate into the corresponding sliding sleeve, and the pressure plate is fixedly installed at the lower ends of the corresponding two sliding rods.

[0011] As a preferred solution, the overlapping limiting section formed between the laterally adjacent pressing plates is provided with a plurality of limiting columns, which are fixedly connected to one of the pressing plates and slidably connected to the other pressing plate.

[0012] As a preferred solution, the roof tiles are fixed to the purlins by screws, and waterproof caps for covering the screws and the screws are installed on the roof tiles and the gusset plates by a hot air welding process.

[0013] As a preferred solution, the roof tiles are provided with slots for the pull rods to move.

[0014] The present invention also provides a construction method for factory building waterproofing and metal plate integrated roof tiles, which is completed by combining factory building waterproofing and metal plate integrated roof tiles, and includes the following steps: S1, first installing purlins and steel wire mesh on the roof, and then laying aluminum foil and glass wool.

[0015] S2. Lay the roof tiles, and overlap and fit the ends of two adjacent roof tiles horizontally.

[0016] S3. Install the gusset plate at the overlap of the roof tiles and tighten it with the reinforcement mechanism.

[0017] S4. Install the waterproof membrane and waterproof cap by hot air welding process, close the transverse seams and cover the screws and bolts.

[0018] One or more of the above-mentioned technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention realizes multi-dimensional optimization of the roofing system by designing the waterproof membrane and roof tiles into an integrated structure, and combining the interlocking locking of interlocking plates, gussets, reinforcement mechanisms, and hot air welding processes. The waterproof membrane is directly covered on the surface of the roof tiles and seamlessly connected to them through hot air welding, eliminating the limitations of traditional sealants. At the same time, the trapezoidal wave structure of the roof tiles is used to form a mechanical locking mechanism with the gussets and reinforcement mechanisms, significantly improving the overall waterproofness, wind-slip resistance, and structural stability of the roof, effectively solving the problems of leakage, aging, and loosening of traditional roofs in complex environments.

[0019] Second, the present invention utilizes a trapezoidal interlocking design of interlocking plates, bilateral pull-on and downward pressure restrictions, and guided positioning of the slide rod and sleeve to form a multi-point coordinated mechanical locking system. This mechanical locking system can simultaneously resist vertical pullout forces and horizontal sliding forces, enhancing the fit and overall rigidity between the roof tiles, gussets, and purlins, and preventing the risk of overlap edge vibration and localized loosening caused by wind pressure.

[0020] Third, this invention uses a TPO waterproof membrane and hot air welding technology to replace traditional sealants, achieving seamless sealing of roof tile joints through fusion bonding. This process eliminates problems such as sealant aging and cracking. Furthermore, waterproof caps shield the screws and bolts, further extending the service life of metal components and ensuring long-term roof stability.

[0021] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a factory building waterproof and metal plate integrated roof tile includes a zigzag roof tile 10 and an inverted concave gusset plate 11, and both surfaces are covered with a waterproof membrane 13; the crests of the left and right ends of the roof tile 10 are provided with a mosaic plate 12 for mutual embedding, and the mosaic plate 12 is an isosceles trapezoidal structure with a larger upper part and a smaller lower part. The gusset plate 11 is buckled and covered at the overlap of adjacent roof tiles 10, and a reinforcement mechanism 2 is provided in the gusset plate 11.

[0034] like Figures 1 to 6As shown, the reinforcement mechanism 2 includes a plurality of screws 20 that are uniformly rotated and installed along the top of the gusset plate 11. The lower end of the screw 20 passes through the gusset plate 11. The upper part of the screw 20 is provided with a positive thread section, the lower part is provided with a negative thread section and the bottom end is provided with a self-tapping screw section. The positive thread section is threadedly connected to a screw disk 21. The front and rear sides of the screw disk 21 are symmetrically hinged with a pull rod 22. The other end of the pull rod 22 is hinged to the inner side of the flank of the gusset plate 11. The negative thread section is threadedly connected to a screw plate 23. A pressure plate 24 is provided on the screw plate 23. An overlapping limit section is formed between the adjacent pressure plates 24 in the horizontal direction.

[0035] like Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, the roof tile 10 is provided with a slot for the pull rod 22 to move.

[0036] like Figure 1 and Figure 2 As shown, waterproof caps 3 for covering the screws 20 are installed on the roof tiles 10 and the gusset plates 11 through a hot air welding process.

[0037] like Figures 1 to 8 As shown, during the specific work, purlins are first erected on the roof, and then steel mesh is laid on the purlins. Aluminum foil and glass wool are then laid on the steel mesh in sequence. After that, the roof tiles 10 are laid. The roof tiles 10 are completely covered from the ridge to the eaves without longitudinal joints, which helps to improve the overall waterproofness and wind resistance, while improving construction efficiency and saving materials. When laying the roof tiles 10, starting from the second roof tile 10, the current roof tile 10 is overlapped with the previous roof tile 10, and the interlocking plates 12 at the ends of the two overlapping roof tiles 10 are interlocked and limited. Then, the waterproof membrane 13 at the end of the upper roof tile 10 is fixed to the lower roof tile 10 using a hot air welding process to seal the joint. Among them, the waterproof membrane 13 can be a TPO roll, which does not contain plasticizers, so there is no problem of brittleness caused by plasticizer migration, and has the advantages of high tensile strength, good wear resistance, strong UV resistance, smooth surface, high reflectivity, and pollution resistance; the hot air welding process refers to the use of high-temperature hot air to melt the TPO roll and bond it to the roll on the lower roof tile 10, and at the same time use a rubber roller to roll it to ensure the welding quality.

[0038] Then, a gusset plate 11 is covered at the crest position of the overlapped joint of the two roof tiles 10, the tie rod 22 is located in the corresponding notch, and the pressure plate 24 is located in the upper interlocking plate 12 (such as Figure 4As shown), the screw 20 is rotated from right to left in sequence, and the screw 20 rotates through the self-tapping screw section at the bottom to penetrate the interlocking plate 12 and the purlin. After that, the screw 20 continues to rotate, and the screw plate 21 engages with the positive thread section and drives the pull rod 22 to pull the side wings of the gusset plate 11 inward so that the side wings press the roof tile 10, thereby ensuring the fit between the roof tiles 10 and between the roof tiles 10 and the gusset plate 11, and improving the overall stability and overall strength of the roof tiles 10 after overlapping. At the same time, the screw plate 23 engages with the counter-threaded section and drives the pressure plate 24 downward to push the interlocking plate 12 against the purlin, locking it tightly. The roofing tile 10 is then secured to the purlin using multiple screws. The waterproof membrane 13 on the flanks of the gusset plate 11 is then hot-air welded to the corresponding roofing tile 10. Finally, a waterproof cap 3, also made of TPO membrane, is hot-air welded to the screws and screws 20, covering them and preventing them from rusting, thereby extending their service life. It should be noted that the waterproof cap 3 is also hot-air welded to the screw mounting area.

[0039] like Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, a pair of slide rods 25 are fixedly installed at the lower end of the screw disc 21, and a sliding sleeve 26 that slides in a one-to-one correspondence with the slide rod 25 is fixedly installed at the lower end of the screw plate 23. The lower end of the slide rod 25 slides through the screw plate 23 to the corresponding sliding sleeve 26, and the pressure plate 24 is fixedly installed at the lower ends of the corresponding two slide rods 25.

[0040] like Figure 5 and Figure 6 As shown, a plurality of limiting posts 240 are provided at the overlapping limiting section formed between the laterally adjacent pressing plates 24 . The limiting posts 240 are fixedly connected to one of the pressing plates 24 and are slidably connected to the other pressing plate 24 .

[0041] like Figures 1 to 8As shown, during the specific operation, during the engagement of the screw 20 threaded section with the screw disc 21, the screw disc 21 cannot rotate under the cooperation of the pull rod 22 and the notch and the limitation of the gusset plate 11. Therefore, as the screw 20 rotates, the screw disc 21 only moves upward. When the screw disc 21 moves upward, the flanks of the gusset plate 11 are pulled inward by the pull rod 22 to fit tightly against the roof tile 10. At the same time, under the limitation of the sliding sleeve 26, the sliding rod 25 and the screw disc 21, the screw plate 23 does not rotate, and the screw plate 23 moves with the screw 20. The screw plate 23 moves downward by rotating, and the pressing plate 24 is pushed downward by the sliding sleeve 26. The pressing plate 24 pushes the interlocking plates 12 to fit tightly against each other and against the purlins. Then the remaining screw rods 20 are installed in sequence, and in the horizontal direction, the rear pressing plate 24 is superimposed on the front pressing plate 24. At the same time, the corresponding limiting column 240 slides through the overlapping limiting section of the two pressing plates 24, so that the multiple reinforcement mechanisms 2 form a whole, thereby improving the overall stability and strength of the gusset plate 11 and the roof tile 10 after overlapping.

[0042] In addition, the present invention also provides a construction method for factory waterproofing and metal plate integrated roof tiles, which is completed by combining factory waterproofing and metal plate integrated roof tiles, and includes the following steps: S1, first build purlins on the roof, then lay steel wire mesh on the purlins and lay an aluminum foil vapor barrier layer on the steel wire mesh, overlap adjacent aluminum foils, and the overlapping width meets the sealing requirements to ensure the flatness of the aluminum foil laying, and then lay a glass wool insulation layer on the aluminum foil, and the glass wool is connected to each other to avoid overlapping, which may cause the glass wool to be too thick in some areas and be collapsed to form hollows, causing uneven roof support and rust risks.

[0043] S2. The roof tiles 10 are laid on the purlins, so that the roof tiles 10 cover the entire roof from the ridge to the eaves without longitudinal joints. The adjacent roof tiles 10 are overlapped and connected in a chiseled state by the chiseled plates 12 to improve the connection quality. Then, the waterproof membrane 13 at the overlapped joints is sealed by the hot air welding process to seal the transverse joints between the roof tiles 10.

[0044] S3. Install the gusset plate 11 at the crest position of the overlapping part of the roof tile 10, and then rotate the screw 20 in sequence to fix it to the purlin. When the screw 20 rotates, the side of the gusset plate 11 will be pulled tightly against the roof tile 10 through the pull rod 22, and at the same time, the pressure plate 24 will squeeze the interlocking plate 12 and fit tightly against the purlin. The pressure plates 24 are overlapped in sequence from left to right, and slide through the overlapping limit sections of the two pressure plates 24 through the corresponding limit columns 240, so that multiple pressure plates 24 form a whole, thereby improving the overall stability and overall strength of the overlapping part of the roof tile 10.

[0045] S4. Through the hot air welding process and rubber roller rolling, the waterproof membrane 13 on the side of the gusset plate 11 is tightly adhered to the corresponding roof tile 10 to close the horizontal seam between the gusset plate 11 and the roof tile 10. Then, the waterproof cap 3 is fixed to the position of the screw and the screw 20 by the hot air welding process again to cover the screw 20 and the screw, thereby extending the service life of the screw 20 and the screw and improving the waterproof effect.
