TECHNICAL FIELD
[0001] The utility model belongs to the technical field of color steel tile, especially relates to a double-layer structure color steel tile and building. BACKGROUND
[0002] Color steel tile is also called color corrugated tile, which is made of color coated steel plate and formed into various corrugated plates by cold rolling, and is widely used in the roof of civil buildings, warehouses, special buildings and large-span steel structure houses.
[0003] At present, the main form of the corrugated shape of the color steel tile on the market is as shown in the accompanying drawings Figure 1 and Figure 2 , which is a single-layer plate structure 1', and the profile line of the corrugated shape 11' in the cross section perpendicular to the axis is an isosceles trapezoidal structure, the isosceles trapezoidal structure includes an upper base end and a waist, and the lower base end is designed as an opening, and the upper base end is arranged at the protruding end of the corrugated shape; when installed, the joints of the plates 1' and 1" are overlapped with each other, and are fixed by screws, for example, the left end screw in the accompanying drawing Figure 2 is the case of the overlapping of the plates. The color steel tile with the structure has the advantages of quick construction and rainproof (water guide) to a certain extent, but has the following problems: firstly, the color steel plate needs to be fixed by screws during construction, but the main material of the color steel plate is iron plate, which is prone to rust at the screw hole, so that the color steel plate gradually rusts around the screw hole with the increase of the use time, and the color steel plate leaks rainwater; secondly, the rainproof level is limited, because the height of the corrugated shape is small, when the rainfall is large, the height of the rainwater may exceed the height of the corrugated shape, at this time, the rainwater may seep into the joint between the plates, causing the color steel plate to leak water, which is a common phenomenon at present; thirdly, the color steel tile is mostly used in the roof, but the temperature of the color steel tile is kept high for a long time due to the direct irradiation of sunlight, which may cause the temperature in the house to rise rapidly, and a high-power air conditioner is needed to reduce the temperature in the house, resulting in high energy consumption in winter; fourthly, when the color steel tile leaks rainwater, the roof needs to be replaced or waterproofed again, which is high in cost. CONTENT OF THE UTILITY MODEL
[0004] The main purpose of the utility model is to provide a double-layer structure color steel tile and building, and the technical problem to be solved is to provide a double-layer structure color steel tile and building, which has high rainproof level, is not easy to rust, has long service life and low cost; and the double-layer structure color steel tile of the utility model has good heat preservation effect and low energy consumption, and is more practical.
[0005] The purpose of the utility model and the technical problem are solved by the following technical scheme. According to the double-layer structure color steel tile provided by the utility model,
[0006] The first layer plate is provided with a plurality of first corrugations parallel to each other; the profile line of the first corrugation in the cross section perpendicular to the axis is a first isosceles trapezoidal structure; the first isosceles trapezoidal structure comprises a first lower base and a first waist, and a first upper base is designed as an opening; the first lower base is arranged at the protruding end of the first corrugation;
[0007] The second layer plate is provided with a plurality of second corrugations parallel to each other; the profile line of the second corrugation in the cross section perpendicular to the axis is a second isosceles trapezoidal structure; the second isosceles trapezoidal structure comprises a second lower base and a second waist, and a second upper base is designed as an opening; the second lower base is arranged at the protruding end of the second corrugation; the first corrugation is sleeved on the outer side of the second corrugation, so that the first layer plate and the second layer plate are connected together.
[0008] The technical problems of the present application can also be further realized by the following technical measures.
[0009] Preferably, the double-layer structure color steel tile further comprises a screw; the screw is arranged on the second corrugation and is used for fixing the double-layer structure color steel tile on a frame; the first corrugation is wrapped on the outer side of the screw.
[0010] Preferably, the double-layer structure color steel tile further comprises a rubber gasket; the rubber gasket is arranged between the screw and the second corrugation.
[0011] Preferably, the double-layer structure color steel tile, wherein the thickness of the rubber gasket is 2mm-15mm.
[0012] Preferably, the double-layer structure color steel tile, wherein the first waist and the first lower base form a first included angle; the second waist and the second lower base form a second included angle; the first included angle and the second included angle are both 30°-60°.
[0013] Preferably, the double-layer structure color steel tile, wherein the first included angle is equal to the second included angle.
[0014] Preferably, the double-layer structure color steel tile, wherein the opening size of the first upper base in the profile line is smaller than the size of the second lower base; the size difference between the second lower base and the first upper base is 10-20mm.
[0015] Preferably, the double-layer structure color steel tile, wherein the height of the trapezoidal structure is 25-35mm, and the lower base width is 65-70mm; the distance between the adjacent two corrugations is 125-150mm.
[0016] Preferably, the aforementioned double-layer structure color steel tile further comprises a functional layer; the functional layer is arranged between the first layer plate and the second layer plate.
[0017] The purpose of the double-layer structure color steel tile and the building is achieved by the following technical scheme.
[0018] The double-layer structure color steel tile and the building have at least the following advantages:
[0019] The double-layer structure color steel tile and the building comprise a first layer plate and a second layer plate; during installation of the color steel tile, the second layer plate is first fixed on a base on which the color steel tile is to be installed, and then the first layer plate is installed above the second layer plate; the key point of the technical concept of the double-layer structure color steel tile and the building is that the corrugations arranged on the first layer plate and the second layer plate have a unique wave shape; the profile line of the first corrugation in a cross section perpendicular to the axis of the first corrugation is a first isosceles trapezoidal structure, which only comprises a first lower base (a longer base of the trapezoid) and two first legs, and a first upper base (a shorter base of the trapezoid) is designed as an opening, that is, the corrugation arranged on the first layer plate is a reversed isosceles trapezoidal structure, which is downwardly open and has a structure of large head and small foot; the overall structure of the second layer plate is the same as that of the first layer plate; this structure design can enable the first layer plate (the upper layer plate) to be installed without any connecting components such as screws, but only need to be connected by inserting the reversed isosceles trapezoidal structure of the second layer plate into the reversed isosceles trapezoidal structure of the first layer plate through the opening of the upper base of the reversed isosceles trapezoidal structure of the first layer plate, so that the first layer plate and the second layer plate are connected together; since the corrugation structures of the two layer plates of the color steel tile of the double-layer structure color steel tile and the building have the reversed trapezoidal structure of large head and small foot, the first layer plate can be firmly connected with the second layer plate to form an integral structure even if the first layer plate is not fixed by a connecting component.
[0020] 1. The first layer plate, that is, the outer layer plate on the upper side, is in long-term contact with rainwater and is easy to be corroded, but the first layer plate of the double-layer structure color steel tile and the building does not need to be installed by punching with screws, thereby avoiding the problem of rain leakage due to corrosion of the screw holes; at the same time, since the outer layer color steel tile does not need to be punched during installation, the service life of the color steel tile is greatly improved compared with traditional color steel tiles.
[0021] 2. After the double-layer corrugated steel roofing is installed, there is a certain distance between the first and second layers. Even under extreme conditions of heavy rainfall, if the amount of rainwater exceeds the height of the first corrugation on the first layer, it will not cause leaks inside the house. Specifically, when the amount of rainwater exceeds the height of the first corrugation on the first layer, only a small amount of rainwater will seep in at the overlap between the two first layers. However, the amount of rainwater that seeps in is extremely small and is almost impossible to exceed the overlap between the two second layers. Therefore, even if a small amount of rainwater seeps in, the second layers are sufficient to drain it smoothly, preventing leaks inside the house. Thus, it can greatly avoid or reduce the need for secondary waterproofing on the roof due to leaks, significantly saving costs.
[0022] 3. Because there is a certain distance between the first and second layers, when the temperature of the first layer rises due to sunlight, its heat needs to pass through the air layer between the two layers to be conducted to the inner layer. On the one hand, the heat conduction takes a long time, and on the other hand, its temperature also decreases after conduction. Therefore, it can better stabilize the indoor temperature, reduce the energy consumption of air conditioning for cooling / heating, and has an energy-saving effect.
[0023] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0029] The utility model provides a double -deck structure color steel tile, such as the following Figure 3 To the following Figure 4 As shown in the figure, it includes:
[0030] The first layer board 1 is provided with a plurality of first corrugations 11 which are parallel to each other; the profile line in the cross section perpendicular to the axis of the first corrugation is a first isosceles trapezoidal structure; the first isosceles trapezoidal structure includes a first lower base and a first waist, and the first upper base is designed as an opening; the first lower base is arranged at the protruding end of the first corrugation;
[0031] The second layer board 2 is provided with a plurality of second corrugations 21 which are parallel to each other; the profile line in the cross section perpendicular to the axis of the second corrugation is a second isosceles trapezoidal structure; the second isosceles trapezoidal structure includes a second lower base and a second waist, and the second upper base is designed as an opening; the second lower base is arranged at the protruding end of the second corrugation; the first corrugation is sleeved on the outer side of the second corrugation, so that the first layer board and the second layer board are connected together.
[0032] In the above technical solution, the trapezoid includes an upper base, a lower base and two waists; the upper base and the lower base of the trapezoid are strictly executed according to the definition of the trapezoid; the longer base is the lower base, which is actually located at the top end of the corrugation, that is, arranged at the upper end of the layer board; the shorter base is the upper base, which is actually located at the bottom end of the corrugation, that is, arranged at the lower end of the layer board; the upper base is designed as an opening in the above technical solution, that is, the trapezoidal structure of the utility model only includes the face corresponding to the lower base and the faces corresponding to the two waists, and the trapezoidal structure is actually a square structure surrounded by three faces.
[0033] In some specific embodiments of the utility model, the double -deck structure color steel tile further includes a screw 3; the screw is arranged on the second corrugation and is used for fixing the double -deck structure color steel tile on the frame or any substrate to be installed; the first corrugation is covered on the outer side of the screw; it is used for protecting the screw hole from directly contacting rainwater and causing rust and other problems, so that the color steel tile of the utility model has a long service life.
[0034] In some specific embodiments of the utility model, the screw is preferably a lengthened screw, so that a longer section is reserved above the second layer board, so that the first layer board has a thicker air layer between the second layer board, so that it can better stabilize the indoor temperature and save energy consumption.
[0035] In some specific embodiments of this utility model, the double-layer structure color steel tile further includes a rubber washer 4; the rubber washer is disposed between the screw and the second corrugation; on the one hand, the washer is used to protect the screw head from direct contact with the second layer plate, avoiding damage to the layer plate and / or disengagement caused by direct hard contact between them; on the other hand, the rubber washer can also make the screw tightly fixed between the second layer plates, improving its installation firmness.
[0036] In some specific embodiments of this utility model, the thickness of the rubber gasket is 2mm to 15mm. In some application scenarios, the thickness of the air layer between the first and second layers can be adjusted by adjusting the thickness of the rubber gasket to achieve a suitable temperature stability and better energy saving. The material of the rubber gasket can be selected according to conventional settings in the art; for example, a silicone rubber gasket can be selected. This utility model does not specifically limit this choice.
[0037] In some specific embodiments of this utility model, the first waist and the first lower bottom end form a first included angle, as shown in the attached figure. Figure 4 Angle α is shown; the second waist and the second lower bottom end form a second included angle, as shown in the attached figure. Figure 4 The β angle shown is 30° to 60°. This design ensures that the bottom dimension of the second layer is larger than the top dimension of the first layer, allowing the first layer to be securely fastened to the second layer. This prevents the first layer from detaching from the second layer under external forces, such as wind, which could damage the double-layer structure of the corrugated steel sheet. If the angle is too large, the reliability of the first layer's connection to the second layer may be affected, potentially leading to the first layer being blown off by wind within the dimensional tolerance range. Conversely, if the angle is too small, it increases manufacturing difficulty and affects rigidity. Preferably, both the first and second angles are 30° to 60°. The angles can differ, as long as the first layer is securely connected to the second layer.
[0038] In some specific embodiments of this utility model, the first included angle is equal to the second included angle; the purpose of this setting is, on the one hand, to make the first trapezoidal structure and the second trapezoidal structure fit together well, and on the other hand, to make the air layer thickness between them uniform; at the same time, the equal included angles also allow the two types of panels to be manufactured using the same angle control parameters, which is more convenient in terms of production line switching and debugging.
[0039] In some specific embodiments of the utility model, the size of the opening of the first upper end of the contour line is smaller than the size of the second lower end; the size difference between the second lower end and the first upper end is 10-20mm, for example, the size of the upper opening of the first layer plate is 38mm, and the size of the lower width of the second layer plate is 50mm. The technical purpose of such arrangement is to ensure that the first layer plate is firmly fixed by being clamped with the second layer plate, and on the other hand, it is convenient for on-site assembly, so that the first layer plate can be combined with the second layer plate under smaller deformation and smaller force; in some use scenarios, the first layer plate can also be combined with the second layer plate by being inserted at the end first and then being pushed along the length direction of the corrugation.
[0040] In some specific embodiments of the utility model, the height of the trapezoidal structure is 25-35mm, and the lower width is 65-70mm; the distance between the two adjacent corrugations is 125-150mm; the technical purpose of such arrangement is to ensure that the mechanical properties of the color steel tile are better, and on the other hand, it is better to guide water and prevent leakage.
[0041] In some specific embodiments of the utility model, the double-layer structure color steel tile further comprises a functional layer, for example, a heat preservation layer, a sound insulation layer, and the specific function can be set according to actual needs, and the utility model does not make specific limitation on this; the functional layer is arranged between the first layer plate and the second layer plate; the functional layer can be arranged as an integral structure with the first layer plate in advance, or it can be arranged during on-site construction, and the utility model does not make specific limitation on this.
