Description

Technical Field

[0001] This invention belongs to the field of building construction and historical building restoration technology, specifically relating to a stabilizing and limiting device for cold-laid tile roofs. Background Technology

[0002] Cold-laid tile roofs are widely found in historical buildings and traditional dwellings in southern my country. Their construction primarily involves rafters supporting dry-laid tiles, utilizing the tiles' own weight and overlapping relationships to achieve waterproofing. While this traditional roof structure is lightweight, breathable, easy to construct and maintain, its lack of effective tile fixing measures results in inherent structural instability. In practical use, relying solely on friction for fixing is insufficient to withstand wind loads or minor deformations of the building's timber structure, leading to frequent tile displacement and slippage, resulting in overlapping damage and roof leaks. Furthermore, its wind resistance is relatively weak.

[0003] To address the aforementioned issues, current repair methods typically employ traditional approaches such as partial patching, weeding and repaving, or complete tile removal and replacement. Alternatively, some solutions involve adding waterproof membrane or sheathing to transform the traditional roof into a closed, modern waterproof layer. However, these existing technologies have significant drawbacks in practical application: First, traditional repair methods only temporarily alleviate symptoms and cannot fundamentally solve the problem of tile displacement due to insufficient friction, leading to recurring leaks, extremely high maintenance frequency, high long-term maintenance costs, and frequent disruption to the building structure. Second, while modern closed-loop repairs using membranes or sheathing improve waterproofing to some extent, they disrupt the traditional roof's "breathable, adjustable, and replaceable" physical structure, increasing roof load and altering the building's original historical appearance. Furthermore, current technology lacks specialized components designed specifically for the characteristics of cold-laid tile structures that can achieve effective stability and easy disassembly and maintenance without compromising the traditional appearance. Summary of the Invention

[0004] The purpose of this invention is to provide a stable limiting device for cold-laid tile roofs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following solution: A stabilizing and limiting device for a cold-laid tile roof, wherein the cold-laid tile roof includes rafters, bottom tiles laid on the rafters, and cover tiles covering the overlap joints of the bottom tiles, comprising: A bottom tile retaining assembly is disposed on the rafter and is used to limit the bottom tile to restrict the sliding of the bottom tile along the length direction of the rafter. A cover tile retaining assembly is disposed on the rafter and is used to limit the cover tile to restrict its tilting and sliding. The bottom tile clamping assembly and the top tile clamping assembly are detachably connected to the rafters.

[0006] Furthermore, the bottom tile fastening assembly includes a U-shaped clamp, the two side walls of which are provided with wings for engaging the bottom tile fins, and the bottom plate of the U-shaped clamp is fixed to the rafter by fasteners.

[0007] Furthermore, the cover tile fastening assembly includes a hook, one end of which has a bent portion for fastening the edge of the cover tile, and the other end of which is fixed to the rafter by a fastener.

[0008] Furthermore, the hook is L-shaped.

[0009] Furthermore, both the bottom tread clamp assembly and the top tread clamp assembly are made of metal.

[0010] Furthermore, both the bottom tread clamp assembly and the top tread clamp assembly are made of galvanized flat iron.

[0011] Furthermore, the bottom tile clamping assembly and / or the top tile clamping assembly are arranged at intervals along the length direction of the rafter.

[0012] Furthermore, the fastener is a self-tapping screw.

[0013] Furthermore, the bottom tile fixing component and the top tile fixing component are located below the bottom tile or the top tile after installation, and do not protrude from the surface of the roof tiles when the roof is completed, forming a concealed structure.

[0014] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes prefabricated metal clips between the rafters and the tiles to provide slotted and hook-like positioning for the bottom and top tiles, respectively. This structure effectively overcomes the slippage and warping problems caused by insufficient friction in traditional cold-laid tiles, without altering the original tile weight and friction transmission mechanism. Experimental data shows that under wind and rain loads, this invention can control tile displacement to an extremely low level, significantly reducing leakage points caused by overlapping damage, ensuring long-term unobstructed roof drainage paths, and significantly reducing the moisture content of wooden components.

[0015] Compared to closed-off repair methods such as adding roofing membranes, this invention does not disrupt the traditional physical structure of roofs—which allows for ventilation, adjustment, and replacement—and does not increase roof thickness or load. The clamps are concealed, so they do not protrude from the roof tiles after installation, thus preserving the building's historical appearance and aesthetic value. Furthermore, the use of detachable connections such as screws ensures the reversibility of the repair measures, meeting the requirement of minimal intervention in the original components for cultural relic preservation.

[0016] This solution resolves the persistent problem of leaks caused by tile misalignment, extending the roof maintenance cycle from the traditional 1-2 years to 3-5 years. This not only reduces frequent disturbances to the building structure but also significantly lowers the overall life-cycle maintenance costs, making it a valuable tool for widespread application.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 7 As shown, this embodiment provides a stabilizing and limiting device for cold-laid tile roofs. The cold-laid tile roof includes rafters 1 arranged parallel to the roof truss slope direction, multiple rows of bottom tiles 2 laid on the rafters 1, and cover tiles 3 covering the overlap joints of adjacent bottom tiles 2. The device of this invention aims to solve the problem of tile slippage by adding a limiting mechanism without disrupting the traditional cold-laid tile construction logic.

[0022] Specifically, the device of the present invention includes a bottom tile fixing assembly 4 and a top tile fixing assembly 5. Both are disposed on the rafter 1 and are detachably connected to the rafter 1.

[0023] like Figure 2 , Figure 5 and Figure 6 As shown, the bottom tile retaining component 4 is used to limit the bottom tile 2, mainly restricting the sliding of the bottom tile 2 along the length direction of the rafter 1 (i.e., the downward direction of the roof slope).

[0024] In this embodiment, the bottom tile fixing component 4 includes a U-shaped clamp 41, which is preferably made of 1.5mm thick galvanized flat iron, providing good corrosion resistance and structural strength. The U-shaped clamp 41 has a width of 55mm and a height of 50mm, and its dimensions are designed to match the specifications of traditional residential roof tiles.

[0025] The U-shaped clamp 41 has inwardly extending wings 42 on both sides, which form a groove for engaging the fins of the bottom tile 2. The base plate of the U-shaped clamp 41 is fixed to the rafter 1 by fasteners. During installation, the U-shaped clamp 41 straddles the rafter 1, and its wings 42 on both sides support the upward-curving edge (i.e., fin) of the bottom tile 2, thereby physically preventing the bottom tile 2 from sliding downward.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the cover tile retaining component 5 is used to limit the cover tile 3, restricting the tilting and sliding of the cover tile 3.

[0027] In this embodiment, the Gewaka Guarantee Assembly 5 includes a hook 51. The hook 51 is also preferably made of 1.5mm thick galvanized flat iron. It is L-shaped or L-shaped, with a length of about 200mm and a height of about 50mm.

[0028] One end of the hook 51 is provided with a bent portion for fastening the edge of the cover tile 3. The bent portion bends upward to hook the lower edge of the cover tile 3, preventing it from tilting up due to negative pressure suction under wind force. The other end of the hook 51 (i.e. the long arm end) is fixed to the side of the rafter 1 by fasteners.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the fasteners are preferably self-tapping screws. Both the bottom tile fixing assembly 4 and the top tile fixing assembly 5 are fixed by directly nailing self-tapping screws into the wooden rafters 1. This connection method is strong and reliable, and also allows for disassembly. When roof repairs or restoration of the traditional structure are required, the fasteners can be removed simply by unscrewing the self-tapping screws, without damaging the original rafters 1, thus meeting the requirements for reversible protection of historical buildings.

[0030] like Figures 5 to 7 As shown, a concealed structure was adopted in order to preserve the appearance of the historical building.

[0031] In specific installation, the bottom tile securing components 4 and the top tile securing components 5 are arranged at intervals along the length of the rafter 1. The spacing L between two adjacent securing components is preferably controlled between 550mm and 650mm, with an optimal spacing of 600mm. This spacing is equivalent to setting one securing point every 10 tiles, which provides sufficient anti-slip resistance while avoiding material waste.

[0032] After installation, both the bottom tile retainer 4 and the top tile retainer 5 are located below the bottom tile 2 or the top tile 3. Viewed from the outside of the roof, the retainers are completely concealed by the upper tiles and do not protrude from the surface of the roof tiles when the roof is finished, thus forming a perfect concealed structure that preserves the rustic rhythm and visual effect of the cold-laid tiles.

[0033] Working principle: Traditional cold-laid tile roofs rely solely on the weight of the tiles and friction for force transmission, resulting in poor stability. This invention, through the aforementioned structure, adds additional lateral and vertical constraints without altering the original force distribution pattern.

[0034] When the roof is subjected to strong wind loads or rain erosion, the downward force on the bottom tile 2 is blocked by the wings 42 of the U-shaped clamp 41; the negative pressure suction (tendency to lift) on the top tile 3 is suppressed by the bent part of the hook 51. Since the clamp does not bear the main vertical load of the roof (which is still borne by the weight of the rafters and tiles), and only serves as a limiting function, even the use of thin metal parts can meet the strength requirements. This design effectively maintains the tight overlap between the tiles, ensures unobstructed drainage paths, and fundamentally reduces the risk of leakage.

[0035] This embodiment further demonstrates that, through precise structural limiting, the present invention significantly improves the wind resistance, earthquake resistance, and waterproof performance of traditional cold-laid tile roofs while retaining their core advantages of breathability and adjustability. It also possesses reversibility and economy, making it an innovative solution in the field of historical building restoration.

[0036] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
