AI Technical Summary
When existing high corrosion-resistant and algae-resistant colored stone metal roofing tiles are installed by stacking them in layers, it is impossible to guarantee a tight fit between the tiles, which leads to rainwater penetration and reduces the waterproof effect.
The metal roofing sheet is equipped with a mating structure consisting of clearance grooves, sealing blocks, epoxy resin strips, sealing channels, cones, overflow holes, and positioning stickers. The epoxy resin strips are bonded together, and the sealing blocks are embedded to ensure a tight seal between the roofing sheets. At the same time, the use of slots, inserts, through grooves, and through holes enables the rapid positioning and fixing of the roofing sheets.
This achieves a sealed fit between the metal tiles, improving waterproofing and ensuring smooth rainwater flow and efficient installation.

Technical Field
[0001] This utility model relates to the field of colored stone metal tiles, and in particular to highly corrosion-resistant and algae-resistant colored stone metal tiles. Background Technology
[0002] High-corrosion-resistant and algae-resistant colored stone metal roofing tiles are a type of roofing material produced using advanced technology. They use high-corrosion-resistant aluminum-zinc coated steel sheets as the base material, with sintered colored sand fixed to the surface using a water-based acrylic adhesive. Finally, a highly weather-resistant acrylic resin is applied as the outermost layer, forming a new type of high-grade roofing material. These tiles not only possess environmentally friendly, waterproof, fire-retardant, sound-absorbing, and impact-resistant properties, but also, due to their special surface materials and processes, exhibit high corrosion resistance and algae-resistant functions. They can maintain their durability in humid or polluted environments, effectively preventing corrosion, oxidation, and algae growth.
[0003] High corrosion-resistant and algae-resistant colored stone metal tiles are mainly fixed to the roof by screws, clamps, and adhesives. Screw fixing requires pre-drilling holes in the roof to ensure accurate hole positions. Clamp fixing usually consists of two parts: one part is located at the bottom of the tile, and the other part is fixed to the roof structure. They can also be fixed to the roof by adhesives or concrete.
[0004] To ensure waterproofing, high corrosion-resistant and algae-resistant colored stone metal tiles need to be stacked layer by layer during installation. However, it is difficult to guarantee a tight fit between the stacked metal tiles during installation, which makes it easy for rainwater to seep into the lower layer of the roof during rainy weather, thereby reducing the effectiveness of the metal tiles. Therefore, a high corrosion-resistant and algae-resistant colored stone metal tile is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high corrosion-resistant and algae-resistant colored stone metal tile, which aims to improve the problem that in the prior art, it is difficult to ensure the tightness of the fit between the tiles when the high corrosion-resistant and algae-resistant colored stone metal tiles are stacked and installed in stages, thus reducing the waterproof effect.

[0013] As a further description of the above technical solution:
[0014] The outer wall of the metal tile has a slot, and an insert is fixedly connected to the outer wall of the metal tile. The upper surface of the metal tile has a through groove, and the surface of the insert has a through hole.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3 This utility model provides an embodiment of a high corrosion-resistant and algae-resistant colored stone metal tile, comprising a metal tile 1, an avoidance groove 2 on the upper surface of the metal tile 1, an epoxy resin strip 4 inside the avoidance groove 2, the epoxy resin strip 4 being made of epoxy resin wrapped in a plastic bag, and the shape of the epoxy resin strip 4 being adaptable to the curvature of the metal tile 1, thereby facilitating its embedding into the avoidance groove 2, a sealing block 3 being fixedly connected to the bottom of the metal tile 1, a sealing groove 5 being opened at the bottom of the sealing block 3, a pointed cone 6 being fixedly connected to the inner wall of the sealing groove 5, several sets of pointed cones 6 being arranged, and several sets of pointed cones 6 being evenly distributed on the inner wall of the sealing groove 5, the pointed cones 6 being able to pierce the plastic bag of the epoxy resin strip 4, causing the epoxy resin to overflow from the inside of the plastic bag, an overflow hole 7 being opened on the surface of the sealing block 3, several sets of overflow holes 7 being arranged, and several sets of overflow holes 7 being evenly distributed on the outer wall of the sealing block 3, the overflow hole 7 allowing epoxy resin to overflow into the avoidance groove 2.
[0033] Reference Figures 3-5The outer wall of the sealing block 3 is adapted to the inner wall of the clearance groove 2, and the inner wall of the sealing groove 5 is adapted to the outer wall of the epoxy resin strip 4. The inner wall of the clearance groove 2 is fixedly connected with a positioning sticker 8. The positioning sticker 8 is a double-sided adhesive sticker and there are several sets. Several sets of positioning stickers 8 are evenly distributed inside the clearance groove 2, which can adhere to the epoxy resin strip 4 and fix it inside the clearance groove 2. By fixing the epoxy resin strip 4 with the positioning sticker 8, it can be connected to the metal tile 1 when the metal tile 1 is installed on the roof, avoiding direct fixation to the surface of the metal tile 1, which would cause the bag to break during transportation.
[0034] Reference Figures 1-3 The outer wall of the metal tile 1 has a slot 9, which is located on the right outer wall of the metal tile 1. A plug 10 is fixedly connected to the outer wall of the metal tile 1, and the outer wall of the plug 10 is fixedly connected to the left outer wall of the metal tile 1. The outer wall of the plug 10 is adapted to the inner wall of the slot 9. By inserting the plug 10 into the slot 9, the metal tiles 1 can be connected in pairs. The upper surface of the metal tile 1 has a through groove 11, and the surface of the plug 10 has a through hole 12. The central axis of the through groove 11 and the central axis of the through hole 12 are on the same horizontal line. After the plug 10 is inserted into the slot 9, the through groove 11 and the through hole 12 are aligned, which makes it convenient to fix the connected metal tiles 1 with cement.
[0035] Working principle: When installing metal tiles 1, after two metal tiles 1 are joined together, another set of metal tiles 1 is needed to complete the stacking installation. Epoxy resin strip 4 is placed inside the clearance groove 2. At this time, the adhesive force of the positioning sticker 8 can fix it and prevent the epoxy resin strip 4 from shifting inside the clearance groove 2. Then, the sealing block 3 is inserted into the clearance groove 2. After the sealing block 3 is gradually inserted into the clearance groove 2, the sharp angle of the cone 6 can pierce the epoxy resin strip 4. After the top metal tile 1 continues to approach the bottom metal tile 1, the sealing block 3 is completely embedded inside the clearance groove 2, and the epoxy resin is squeezed out from the epoxy resin strip 4. After the epoxy resin overflows from the overflow hole 7, it can bond the stacked metal tiles 1, thereby ensuring the sealing between the metal tiles 1. Repeat the above steps to install the metal tiles 1 step by step, thereby ensuring the smooth flow of rainwater and achieving the purpose of waterproofing.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
