Description

Technical Field

[0001] The present application relates to the field of architecture, and in particular to a decorative structure of longitudinally spliced ​​horizontal panels. Background Art

[0002] The roof is the outer protective component of the top layer of the building, which mainly plays the role of waterproofing and isolating the external environment. The roof of the building is exposed to wind and sun for many years. If there is a leak in the roof waterproof layer, it is easy to cause the waterproof layer to be damaged, the wall to seep, and the wall surface to corrode, affecting normal life. The structure of the waterproof coating that uses asphalt roll materials or waterproof coatings, which is widely used at present, still has many problems, such as uneven thickness and difficult to control mechanical indicators, resulting in a short service life of the roof waterproof structure. The same situation is also true for the exterior wall facade.

[0003] Therefore, roofs similar to traditional tile structures have been recognized by the market again. However, the inventors found that the existing rainproof structures installed on roofs are complex and inconvenient to disassemble and assemble, especially they cannot take into account the functional characteristics of rainproof, noise reduction when rain falls, and easy installation. At the same time, the relevant products are only suitable for laying on roofs, and cannot be laid on exterior walls. Summary of the invention

[0004] In order to solve the above technical problems, the present application discloses a decorative structure of longitudinally spliced ​​horizontal panels, which is applied to roofs or walls, and includes one or multiple horizontal panel units spliced ​​together, wherein the horizontal panel units are wedge-shaped structures as a whole, and the thinner side of the wedge-shaped structure has an upper curling edge, and the thicker side of the wedge-shaped structure has a lower curling edge.

[0015] a third bending portion connected to the second bending portion and not coplanar;

[0016] In the upper curling edge, at least the third bent portion and the lower curling edge of the corresponding transverse plate unit overlap with each other.

[0017] Optionally, among two adjacent horizontal plate units, the lower one is the first module, and the higher one is the second module. The main bodies of the roof layers of the two modules are on different surfaces and a step structure is formed at the splicing position; the main body of the roof layer of the second module protrudes out of the first bending part of the first module to form a step front edge, and the upper curling edge and the lower curling edge that cooperate with each other are located below the step front edge.

[0018] Optionally, the first bending portion of the first module extends upward to near the bottom surface of the body of the second module, the second bending portion is in contact with the bottom surface of the body of the second module and extends in the same direction, and the lower curling edge of the second module and the third bending portion of the first module overlap each other;

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] Unless otherwise specified, the relative directions such as upper and lower mentioned in this application are based on the attached Figure 2From the perspective of the wall, when the decorative structure is used on the wall, the relative directions such as up and down are converted to the inner and outer sides of the wall, which is equivalent to the attached Figure 2 Rotate the view in 90 degrees.

[0047] refer to Figures 1 to 11 The present application discloses a decorative structure of longitudinally assembled horizontal boards, which is applied to roofs or walls. The horizontal board unit includes a bottom board layer 1, a filling layer 2 and a roofing layer 3 stacked in sequence from bottom to top in its thickness direction. One of the two opposite sides of the roofing layer 3 has an upper curling edge 31 and the other side has a lower curling edge 32.

[0048] When multiple horizontal plate units are spliced, each horizontal plate unit itself extends horizontally along the roof or wall, and two adjacent horizontal plate units are spliced ​​longitudinally along the roof or wall. In the two adjacent horizontal plate units, the upper curling edge 31 of the lower one and the lower curling edge 32 of the higher one are matched and fixed to each other.

[0049] The opposite sides of the roofing layer 3 refer to the two sides of the roof or wall in the longitudinal direction. The longitudinal direction should be understood as the direction in which the water flow of the decorative structure is driven by gravity to slide down, that is, the adjacent module units are spliced ​​in sequence in the longitudinal direction; in the transverse direction, the module units themselves extend to cover a larger area to improve the efficiency of the laying construction. The functions of the upper curling edge 31 and the lower curling edge 32 are to achieve a sealed connection between adjacent module units and take into account the strength of each module unit. Therefore, the shape of the curling edge in this embodiment is not strictly limited and has more designs. Figure 4 , Figure 7 , Fig.10 as well as Fig.11 The above-mentioned figures show several exemplary designs of curling edges.

[0050] For example, in one embodiment, the roofing layer 3 is an integrated structure, specifically including a body 33 and an upper curling edge 31 and a lower curling edge 32 distributed on opposite sides of the body 33, wherein the upper curling edge 31 includes:

[0051] A first bent portion 311 connected to the body 33 and extending upward;

[0052] A second bending portion 312 connected to the first bending portion 311 and not coplanar with the first bending portion 311. Relative to the first bending portion 311, the second bending portion 312 is inclined downward toward the top surface of the body 33, or is folded back and attached to the first bending portion 311;

[0053] In the upper curling edge 31 , at least the second bent portion 312 and the lower curling edge 32 of the corresponding transverse plate unit overlap with each other.

[0054] In this design, the first bent portion 311 can effectively improve the strength of the module unit. The second bent portion 312 can achieve a sealing effect when cooperating with the lower curling edges 32 of two adjacent transverse plate units.

[0055] For example, refer to Figure 3 and Figure 6 In one embodiment, the roofing layer 3 is an integrated structure, specifically including a body 33 and an upper curling edge 31 and a lower curling edge 32 distributed on opposite sides of the body 33, wherein the upper curling edge 31 includes:

[0056] A first bent portion 311 connected to the body 33 and extending upward;

[0057] A second bent portion 312 connected to the first bent portion 311 and bent back toward the side where the lower curling edge 32 of the body 33 is located;

[0058] a third bending portion 313 connected to and not coplanar with the second bending portion 312;

[0059] In the upper curling edge 31 , at least the third bent portion 313 and the lower curling edge 32 of the corresponding transverse plate unit overlap with each other.

[0060] Compared with the previous technical solution, this embodiment increases the number of bends of the lower curling edge 32, which can further improve the strength of the module unit in principle. Accordingly, increasing the number of parts that cooperate with the lower curling edges 32 of two adjacent horizontal plate units can change the route of rainwater intrusion into the decorative structure, thereby optimizing the waterproof effect. However, the increase in the number of bends will increase the corresponding process and the requirements for precision, so the specific number of bends can be adjusted according to the needs of different buildings. Figure 4 , Figure 7 , Fig.10 as well as Fig.11 The solutions shown in all belong to this embodiment, and the difference lies in the different settings of the third bending portion 313. Fig.10 and Fig.11 The embodiment shown in FIG. 1 differs from the embodiment shown in FIG. 2 in that the lower bead 32 is different.

[0061] In the above two schemes, the upper curled edge 31 is matched with the lower curled edge 32 of the two adjacent horizontal plate units after bending. From a structural point of view, the plate structures of the two adjacent horizontal plate units are overlapped and rolled, rather than being stacked after being folded. However, from an assembly process point of view, assembly can be achieved by at least a part of the pre-folding process through nesting, docking and pressing.

[0062] Regarding the coordination of the bending portions, in one embodiment, relative to the second bending portion 312 , the third bending portion 313 droops toward the top surface of the body 33 , or is bent obliquely toward the first bending portion 311 , or is folded back and attached to the bottom surface of the second bending portion 312 .

[0063] In this embodiment, the three configurations of the third bending portion 313 actually form a semi-enclosed structure at the upper curling edge 31, which can better achieve the sealing function. The upper curling plate cooperates with the lower curling edge 32 of the corresponding horizontal plate unit to reinforce each other and better engage with each other.

[0064] The extension paths of each bent portion on the cross section can be various. In one embodiment, each bent portion in the upper curling edge 31 itself extends along a straight line or a curve.

[0065] When each bending part extends along a straight line, it is easy to produce and has good adaptability to matching tolerances, which is convenient for assembly and laying construction; when each bending part extends along a curve, it has the advantage of better matching with the lower curling edge 32 of the corresponding horizontal plate unit, and the possibility of precipitation invading the matching part is smaller. When the horizontal plate unit is subjected to force, it can be positioned with each other through the curved surface formed by the extension of the curve to avoid displacement. For example, in one embodiment, the upper curling edge 31 is a curved surface structure as a whole, and the transition between each bending part is smooth. In this embodiment, in addition to the above advantages, the curved surface also has the advantages of avoiding stress concentration and mutual wear, thereby improving the durability of the overall roof or wall.

[0066] The most important thing about the design of the multiple bends of the upper curling edge 31 is the coordination with the lower curling edge 32. In terms of coordination, in one embodiment, of the two adjacent horizontal plate units, the lower one is the first module, and the higher one is the second module. The main bodies 33 of the roofing layers 3 of the two modules are on different surfaces and form a step structure at the joint; the main body 33 of the roofing layer 3 of the second module protrudes out of the first bend 311 of the first module to form a step front, and the upper curling edge 31 and the lower curling edge 32 that cooperate with each other are located below the step front.

[0067] The upper curling edge 31 and the lower curling edge 32 of each horizontal plate unit are not only "up" and "down" in the longitudinal direction of the roof or wall, but also have a height difference in the gravity direction, thereby realizing a step structure at the splicing part. After the adjacent horizontal plate units are combined, a step shape similar to a tile is formed, thereby guiding precipitation away from the roof.

[0068] In terms of the specific coordination of the bending structure, in one embodiment, the first bending portion 311 of the first module extends upward to the vicinity of the bottom surface of the body 33 of the second module, the second bending portion 312 is in contact with the bottom surface of the body 33 of the second module and extends in the same direction, and the lower curling edge 32 of the second module and the third bending portion 313 of the first module overlap each other;

[0069] The ends of the lower curling edge 32 of the second module and the third bending portion 313 are flush with each other, or the lower curling edge 32 of the second module extends beyond the end of the third bending portion 313, and the extended portion is coplanar with the portion before extension or is further bent along the original curling trend.

[0070] The upper curling edge 31 and the lower curling edge 32 are engaged with each other through the bent portion, thereby improving the waterproof performance and the strength at the same time.

[0071] In one embodiment, a reinforcing plate 34 is sandwiched between the upper bead 31 and the lower bead 32 , and the reinforcing plate 34 further extends between the bottom plate layer 1 and the roofing layer 3 at the higher position.

[0072] The reinforcing plate 34 in this embodiment also fits between the upper curling edge 31 and the lower curling edge 32 of the adjacent transverse plate unit, and can be pressed together during the assembly process of the upper curling edge 31 and the lower curling edge 32. In addition to improving the assembly strength of the two, the reinforcing plate 34 also has the function of ensuring assembly parameters. For example, by setting the thickness, position, length, width and other parameters of the reinforcing plate 34, the matching parameters of the upper curling edge 31 and the lower curling edge 32 can be controlled.

[0073] In the setting of the bottom plate layer 1, in one embodiment, the horizontal plate unit is a wedge structure as a whole, and the bottom plate layer 1 is a corrugated structure. The amplitude of the corrugated structure changes gradually and the change trend is consistent with the thickness change trend of the wedge structure; the roof layer 3 has an upper curling edge 31 on the thinner side of the wedge structure and a lower curling edge 32 on the thicker side of the wedge structure. When multiple horizontal plate units are spliced, the upper curling edge 31 of one of the two adjacent horizontal plate units and the lower curling edge 32 of the other are fixed to each other. The corrugated structure forms a cavity at the bottom of the horizontal plate unit, so that each horizontal plate unit has a certain thickness space in the direction of gravity, which is conducive to noise reduction and heat preservation. The gradual change in the amplitude of the corrugated structure can adapt to the appearance requirements of the horizontal plate unit, so as to adjust the distance between the top surface of the building and the roof layer 3 as needed, providing a structural basis for more functions.

[0074] It is not difficult to understand that the bottom plate layer 1 needs to support the filling layer 2 and the roofing layer 3, so a certain structural strength is required. In one embodiment, the shape of the crest or trough of the bottom plate layer 1 is a triangle, a quadrilateral or an arc. Among the various shapes in this embodiment, the cross-sectional shapes are described. While ensuring the structural strength, there is also a certain internal space, so as to achieve the function of sound insulation and heat preservation. The one shown in the accompanying drawings is a trapezoid.

[0075] In terms of the arrangement of the internal space, in one embodiment, a plurality of cavities arranged at intervals are formed between the filling layer 2 and the bottom plate layer 1. The increase in the number of spaces can block the air exchange inside each space, thereby improving the sound insulation and heat preservation effects.

[0076] In the installation of the bottom plate layer 1, in one embodiment, in the corrugated structure, the vertices of all the troughs are coplanar and used to be fixed with the keel 11, and the vertices of all the crests are coplanar and carry the filling layer 2. The coplanar bearing of the vertices of the crests can improve the force-bearing performance of the bottom plate layer 1, and can also ensure the flatness of the filling layer 2, providing a basis for the laying of the roofing layer 3. Specifically, in one embodiment, in the corrugated structure, each trough part and each crest part are respectively a plane structure. The trough part and the crest part of the plane structure can increase the contact area between the bottom plate layer 1 and other components, thereby improving stability.

[0077] In terms of the details of the filling layer 2, in one embodiment, the filling layer 2 includes a leveling layer 21, a waterproof layer 22, and a noise reduction layer 23 stacked in sequence from bottom to top. The leveling layer 21 can further make up for the flatness of the bottom plate layer 1 and reduce the precision requirements for the bottom plate layer 1; the waterproof layer 22 can protect the internal structure in the event of waterproof failure of the roofing layer 3, thereby extending the service life of the roof or wall; the noise reduction layer 23 can further reduce the sound generated by precipitation and the like, thereby improving the living comfort of the building.

[0078] Corresponding to the roofing layer 3, the bottom plate layers 1 can also be interlocked with each other, but it will increase the difficulty of laying. Therefore, in one embodiment, in two adjacent horizontal plate units, the edges of the bottom plate layers 1 of the two sides directly abut or partially overlap. The bottom plate layers 1 of two adjacent horizontal plate units do not need to be very tightly connected, and the two can limit each other to prevent relative displacement.

[0079] During the construction of the roof or wall, a keel 11 is set up on the top surface of the building, and the base plate layer 1, the leveling layer 21 of the filling layer 2, the waterproof layer 22, the noise reduction layer 23 are laid in sequence, and finally the roofing layer 3 is laid. Adjacent horizontal plate units are engaged with each other through the reinforcing plate 34, the upper rolled edge 31 and the lower rolled edge 32 to achieve stable installation of the roof or wall.

[0080] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0081] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
