Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a wood-plastic profile and a lighting system. Background Art

[0002] Many existing buildings' exterior walls, fences and other facade wall structures have gradually reduced the use of wooden boards, and are increasingly using wood-plastic board structures. The advantages are reduced consumption of wood resources, relatively low material costs, and reduced time costs due to assembly line processing. They are not easily affected by moisture, rot or deformation, have a long service life, good flame retardancy, relatively high safety, high plasticity, can have various styles of templates, and are more decorative. There are also many existing patented technologies for wood-plastic profiles.

[0003] For example, a large-scale wood-plastic sound insulation partition wall panel profile disclosed in Chinese patent application number 201410643364.1 includes a wall panel, characterized in that a rectangular hole is provided in the middle of the core of the wall panel, and a plurality of square holes are symmetrically provided on the left and right sides of the core of the wall panel, and a rectangular protrusion is provided in the middle of each of the four sides of each square hole, a rectangular plug is provided at the left end of the wall panel, and a right-facing open groove adapted to the rectangular plug is provided at the right end of the wall panel, and a plurality of trapezoidal teeth are symmetrically provided on the upper and lower sides of the right-facing open groove.

[0004] For example, Chinese patent application number 201410644188.3 discloses an assembled wood-plastic double-sided wall panel profile, which includes a wall panel, characterized in that: a right-hand opening groove is provided at the right end of the wall panel, and an arc-shaped protrusion is provided on the right side of the lower side of the right-hand opening groove, a plurality of arc teeth are provided on the upper surface of the wall panel, a rectangular plug adapted to the right-hand opening groove is provided at the left end of the wall panel, and an arc-shaped groove adapted to the arc-shaped protrusion is provided on the bottom surface of the rectangular plug, and a small rectangular hole and four large rectangular holes are provided in the core of the wall panel from left to right.

[0005] For example, Chinese patent application number 200920123876.X discloses a wood-plastic profile for wall cladding, comprising a body, wherein a boss I and a boss II are provided on the outer side of the body, a through groove is provided between the boss I and the boss II, and a connecting structure is formed on the outer sides of the body at the boss I and the boss II, which correspond to each other. The connecting structure comprises an embedding groove provided on the outer side of the boss I, a protrusion I formed at the bottom of the groove, a protrusion II provided on the outer side of the boss II corresponding to the embedding groove, and a hollow groove formed at the bottom of the protrusion II corresponding to the protrusion I. The protrusion II is embedded in the embedding groove while the protrusion I is embedded in the hollow groove to achieve connection.

[0006] The wood-plastic profiles involved in the above-mentioned existing patented technologies have achieved good results, but there are still deficiencies in the design of lighting. In particular, in many occasions, the facade structure requires lighting facilities. Then, many existing practices are to drill many holes in the main structure of the profile for the installation of lighting facilities. This not only destroys the profile structure, but also makes the operation very troublesome.

[0007] Or some existing methods use floors or interior facades for lighting, that is, setting light strips in the concave position on the front of the board or setting lamp bodies in the internal grooves, such as the Chinese patent application number 202221666140.9 discloses a wood-plastic wall panel with a good lighting effect that can be worn with light strips, including a wood-plastic wall panel body, a connecting strip fixedly connected to the middle of the top of the wood-plastic wall panel body, a connecting slot provided in the middle of the bottom end of the wood-plastic wall panel body, a fixing groove provided in the middle of one side of the wood-plastic wall panel body, and a fixing strip fixedly connected to the middle of the other side of the wood-plastic wall panel body. Users can pass the light strip through the wood-plastic wall panel through the light strip perforation and transmit the light through the prismatic glass cover on the installation cavity and refract it through the prismatic glass cover, thereby increasing the beauty of the light transmitted out of the light strip in the installation cavity and improving the beauty of the overall decoration of the indoor wood-plastic wall panel. The above-mentioned method is not suitable for exterior facades. On the one hand, the lighting effect is not suitable for external use. On the other hand, the excessive number of parts is not conducive to the use of large exterior walls. It is prone to failure and the cost of installation and maintenance is too high.

[0041] The present invention will be described in further detail below with reference to the accompanying drawings.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0043] Example 1, as Figure 1-12 As shown, a wood-plastic profile is suitable for use on the surface of a building structure, for example, a building facade, such as an exterior wall, a fence, a fence, etc., or can also be used as a horizontal building surface, for example, as a floor surface. The wood-plastic profile of this embodiment is mainly used for facade use, and the effect of use on the facade is very good. Of course, it is not limited to facade use.

[0044] The wood-plastic profile specifically includes two or more main wall parts 1 arranged at intervals, and the two adjacent main wall parts 1 are connected as a whole through a secondary connecting basic wall part 2. The main wall part 1 and the secondary connecting basic wall part 2 are both made of wood-plastic materials. The main wall part 1 occupies a larger volume, uses more materials, and has a larger length. In simple terms, most of the area that the observer can see is mainly the main wall part 1. On a profile, there can be 3, 4, 5 main wall parts 1, etc., generally more than two but not too many, and the secondary connecting basic wall part 2 plays the role of connecting the main wall parts 1, connecting multiple main wall parts 1 into a wall monomer, that is, connecting them into a whole piece of wood-plastic profile. Among them, the secondary connecting base wall part 2 extends in two directions. Taking the facade as an example, the profile is upright. On the one hand, the secondary connecting base wall part 2 extends upright in the up and down directions, and on the other hand, the secondary connecting base wall part 2 needs to extend in the left and right directions, that is, the entire profile is continuous in the horizontal direction, and at least a part of the main wall part 1 protrudes from the secondary connecting base wall part 2 and forms a three-dimensional expansion side support wall 3. For example, a part of the main wall part 1 protrudes forward from the secondary connecting base wall part 2, or a part protrudes backward from the secondary connecting base wall part 2, or a part protrudes forward and backward from the secondary connecting base wall part 2, then this protruding part forms a three-dimensional expansion side support wall 3, this wall structure protruding forward and / or backward The structure makes the wall that originally looks relatively flat have an expanded structure in the direction of intersection, which can realize a three-dimensional structural design and a three-dimensional structural sense. The three-dimensional expanded side support wall 3 as a whole is preferably perpendicular or approximately perpendicular to the secondary connecting foundation wall part 2, because the three-dimensional expanded side support wall 3 is usually a flat board wall structure, but at some splicing positions, the side of the three-dimensional expanded side support wall 3 will have an abnormal deformation, and it is not a flat board. Of course, the three-dimensional expanded side support wall 3 as a whole can also be slightly tilted to the left or right and be in a non-vertical intersection with the secondary connecting foundation wall part 2. The acute angle formed by this intersection between the two is roughly controlled between 60 degrees and 90 degrees, that is, it will not be too tilted. Excessive tilt will have a greater impact on strength and support. Therefore, basically, the three-dimensional expansion side support wall 3 and the secondary connection foundation wall part 2 are in a cross shape, or the three-dimensional expansion side support wall 3 is slightly tilted to the left or right and then tilted to cross with the secondary connection foundation wall part 2. In this way, there is a structural extension in the horizontal left and right directions. No matter how much it tilts, there is also sufficient structural extension in the horizontal front and back longitudinal directions. The profile itself is extruded and naturally extended in the up and down directions, so the three-dimensionality of the entire structure is better.Furthermore, at least one of the three-dimensional expansion side support walls 3 is formed with a through side assembly groove 30 for inserting and installing other workpieces. After the side assembly groove 30 is extruded and formed into the profile, it is in a vertical through-type style when used in the facade, and the side assembly groove 30 is arranged on the side of the three-dimensional expansion side support wall 3, such as on the left and / or right side, that is, not on the front side. The front side is the front or back position that can be directly observed, and the side here is the surface where the left and right sides are located relative to the front and back directions, or the two sides next to the front side. In this way, the side assembly groove 30 cannot be observed from the front or is very difficult to observe, that is, it is a concealed slot. The other workpieces can be light strips, fluorescent decorative strips, or a part that can expose the side assembly groove 30 and is located New Year decorations, ribbons, etc. between the main wall parts 1, or some reinforced installation connectors, such as some reinforced aluminum profiles, are inserted into the side assembly groove 30, and decorative billboards are installed on its side, etc., which can all be applied. The most important point of this design is that the side assembly groove 30 is a concealed slot, which is basically not observable. In terms of aesthetics, it is very good. In this embodiment, we strongly recommend the use of light strips for the workpiece, which have a very good effect when used on the facade. Like traditional facade walls, lamps are directly exposed and illuminated from the front, and the installation of lamps also requires the intervention of aluminum alloy profiles, etc. and usually holes are punched in the profile itself for installation. The appearance and lighting effects are not so good, and the profile itself needs further processing during construction. The present application is different. The side assembly groove 30 is a concealed groove. The groove is not visible or difficult to see from the front, and the light bar is also concealed in the side assembly groove 30, that is, the light bar itself is not visible or difficult to see, which is very beautiful. The structure other than the wall itself will not be seen. It is simple and clear. Moreover, such a structure allows the light bar to emit light from the side. The advantage of this light-emitting method is that part of it can illuminate the front area, and part of it can illuminate the front side or rear side of the adjacent three-dimensional expansion side support wall 3 and the auxiliary connection base wall part 2. Reflecting light will make the wall and light more compatible, so that both the light and the wall itself can be well displayed. This can be achieved thanks to the material of the wood-plastic board itself. Although the wood-plastic board has wood components, the fluidity of the plastic is better during the molding process. The so-called outer surface is almost made of plastic, so the finish and glossiness are better, and it has a good reflective effect on light. At the same time, colored components or components suitable for reflective light can be added to the plastic components, so the color of the light and the luminous effect can be effectively controlled.Of course, the side assembly groove 30 is a through groove in the molding direction of the wood plastic board. If it is used in the facade, it is a through groove extending up and down, because the extrusion molding process of the wood plastic board is completed in a straight direction, and the cross section is the same, that is, when viewed from the facade, the straight groove extending up and down forms two upper and lower groove end outlets, but because light needs to be emitted from the side, a corresponding notch structure and a limiting structure need to be formed on the side of the side assembly groove 30. Specifically, the three-dimensional expansion side support wall 3 is also formed with a groove located on the side assembly groove. The slots on the side of the side assembly slot 30 are located at the side limiting wall c for limiting the position of the workpiece in the side assembly slot 30. The side limiting wall c only blocks a portion of the slots on the side of the side assembly slot 30, thereby forming a side opening 301. That is, the side limiting wall c blocks a portion of the slots on the side of the side assembly slot 30 to reduce the size of the slots, and then forms a new side opening 301 through the side limiting wall c. The side opening 301 is connected to the side assembly slot 30 on the side and is further outward. Traditional facades either have direct lights that are too dazzling, or the light will be dim if the power is reduced. In particular, the lighting effect on the exterior wall itself is also relatively poor. The lighting effect is not very good, and there are many redundant external structures, which require more operating costs and the effect is also average. The cost of the profile in this embodiment mainly lies in the design of the profile structure, the production and testing of the corresponding mold, and the selection and adjustment of the plastic component in the wood-plastic material. However, this cost increase is very low compared to the on-site operation and the use of redundant components such as traditional wood, wood-plastic or aluminum profiles. In addition, the damage to the profile itself is less, and the use effect is very good. In addition, the price of the wood-plastic material itself is relatively low. Therefore, both in terms of production and use, it has specific economic and social significance.

[0045] Furthermore, the three-dimensional expansion side support wall 3 is integrally connected to a suspended wall portion 4 on the side away from the secondary connection base wall portion 2. The main wall portion 1 is in the shape of a long through hole and the hole wall at the through hole position at least includes the three-dimensional expansion side support wall 3 and the suspended wall portion 4. The suspended wall portion 4 is actually the main wall surface of the main wall portion 1, and is also the main wall surface where the profile can be directly observed. Because the three-dimensional expansion side support wall 3 is extended and extended beyond the secondary connection base wall portion 2, a three-dimensional suspension feeling is formed. The structure itself is more beautiful while ensuring stability. When the facade is in use, the main wall portion 1 extends in the vertical direction and is in the shape of a through hole. The through hole t in the main wall portion 1, which is in the shape of a long through hole, also extends in the vertical direction. It can be seen that the cross section of the main wall portion 1 is as closed as possible, that is, the figure on the horizontal projection plane formed by the vertical projection is a figure surrounded by the front, back, left and right. The figure surrounded by the figure is stretched in the vertical direction to form the three-dimensional structure of the main wall portion 1 of this entity. The main components of this surrounded structure, that is, the three-dimensional expansion side support wall 3 and the floating wall portion 4, which can serve as the hole wall. In addition, according to the actual use situation, the closed loop of the entire structure is completed by adding a solid entity. The details will be further explained later. Then the most important design above is the design of the three-dimensional expansion side support wall 3 and the optimization of the side structure, especially the concept of the side assembly groove 30, which can change the installation method and decorative effect of the traditional decorative structure design, save installation costs, reduce structural damage, etc. It is safe and stable to use and more beautiful. It is a very good design improvement.

[0046] The realization of the entire concept also requires the intervention of the following specific plans. The following orientations are all orientations observed when the profile is used as a facade building structure. For example, the left side of the main wall part 1 on the far left is integrally connected with a female plug-in wall part 51, and the right side of the main wall part 1 on the far right is integrally connected with a male plug-in wall part 52 for plugging and cooperating with the female plug-in wall part 51, or the left side of the main wall part 1 on the far left is integrally connected with a male plug-in wall part 52, and the right side of the main wall part 1 on the far right is integrally connected with a female plug-in wall part 51 for plugging and cooperating with the male plug-in wall part 52. The structural design here is mainly for the purpose of plug-in splicing between each profile. This splicing structure is also a commonly used structure for existing profiles. For example, a male plug-in wall part 52 is integrally connected to the right side of the main wall part 1. The male plug-in wall part 52 can be a straight-line flat plate structure and is integrally connected to the right side wall of the rightmost three-dimensional expanded side support wall 3 of the rightmost main wall part 1. The female plug-in wall part 51 can be a concave structure with an opening facing left and is integrally connected to the left side wall of the leftmost three-dimensional expanded side support wall 3 of the leftmost main wall part 1. This left-facing opening is a plug-in interface for the male plug-in wall part 52 to be inserted for splicing, and the front and rear parallel plates in this concave structure are shorter, or the plate near the front is shorter, and the plate near the back is longer. This plate near the back can be called a positioning reinforcement plate j, because in the process of profile splicing, the profile is preferably further connected to the inner wall or the wall keel. The positioning reinforcement can be further strengthened, and this can be achieved by further fixing the positioning reinforcement plate j to the inner wall or the wall keel, and a positioning reinforcement groove j1 is formed on the front side of the positioning reinforcement plate j and on the part of the short plate that exceeds the front left and right. The positioning reinforcement plate j is located at the middle position on the left and right of the bottom of the positioning reinforcement groove j1, and is further recessed backward and extends up and down to form a locking member preset groove j11. The locking member is a screw or a round nail, etc., which can be nailed into the positioning reinforcement plate j through the locking member preset groove j11 and then nailed to the inner wall or the wall keel, and the head of the nail falls in the positioning reinforcement groove j1, so that the entry of the male plug-in wall part 52 is not affected during splicing, and the flatness is guaranteed. Then the upper and lower parts can be in the same positioning reinforcement groove j1, and multiple nails can be nailed in separately up and down and penetrate into the wall or the wall keel, so that the profile can be further strengthened and positioned, thereby ensuring the stability of the installation structure.Another structure of the female plug-in wall portion 51 is that the female plug-in wall portion 51 is a straight-line and nearly flat structure of the positioning reinforcement plate j, which also has a positioning reinforcement groove j1 and a locking member preset groove j11. However, the left side and rear portion of the leftmost three-dimensional expansion side support wall 3 itself forms a concave structure with an opening facing left, that is, this plug-in interface is formed on the three-dimensional expansion side support wall 3, and at this time, the female plug-in wall portion 51 is integrally connected to the left end of the rear plate in this concave structure. This structure saves on the use of profile materials, is relatively more beautiful, and has a more compact structure. The front and rear plates of the concave structure can further form a latching tooth on the plate surface located within the plug-in interface, so that the male plug-in wall portion 52 can be better locked after insertion. Because the wood-plastic board still has a certain plasticity, it can also be better assembled. Of course, this latching tooth is very small and does not affect the insertion of the male plug-in wall portion 52. This structure is suitable for the facade structure of a single-sided wall. Here, the front part is used as the wall body, and the positioning reinforcement plate j is designed to be positioned at the back, including the male plug-in wall part 52 and the female plug-in wall part 51. They are both positioned at the back in order to be close to and further connected with the rear inner wall or the wall keel, etc., so the profile has the visual effect of only one side of the wall.

[0047] Preferably, at least one of the main wall portions 1 has two three-dimensional expansion side support walls 3 spaced apart from each other. The front ends of the two three-dimensional expansion side support walls 3 are integrally connected to the floating wall portion 4. Here, I mainly recommend the design of two three-dimensional expansion side support walls 3. This structure has a better effect and uses less materials. Furthermore, the rear ends of the two three-dimensional expansion side support walls 3 are integrally connected to a rear reinforcement connecting wall portion 6. The rear reinforcement connecting wall portion 6 is a straight-line flat plate. The floating wall portion 4, the two three-dimensional expansion side support walls 3, and the rear reinforcement connecting wall portion 6 are surrounded and connected. This structural design forms a closed surrounding structure, and also forms the aforementioned through hole t.

[0048] Next, we introduce two different implementation plans, which are mainly designed for different facade building requirements:

[0049] The first type is that the secondary connecting foundation wall part 2 is in a straight line and is located at the rear end of the main wall part 1. The main wall part 1 has two three-dimensional expansion side support walls 3. Furthermore, the secondary connecting foundation wall part 2 and the rear reinforced connecting wall part 6 are kept in the same straight line as much as possible or the front and rear positions are consistent as much as possible. It can be understood that the secondary connecting foundation wall part 2 and the rear reinforced connecting wall part 6 are both in the same rear position, so that the structures of the suspended wall part 4 and the two three-dimensional expansion side support walls 3 in the main wall part 1 are almost all on the front side of the exposed structure of the secondary connecting foundation wall part 2. In this way, the main wall part 1 is in a state of completely protruding forward, so such a structure is used as a single wall surface, such as the single-sided facade such as the exterior wall of a house, that is, a structure used as one side wall surface, for example, according to the above, the front side wall is used here.

[0050] Furthermore, at least one of the three-dimensional expanded side support walls 3 on the right side of the main wall part 1 has a side assembly groove 30 and / or at least one of the three-dimensional expanded side support walls 3 on the left side of the main wall part 1 has a side assembly groove 30, and the side assembly groove 30 is located in front of the secondary connecting basic wall part 2. Here, the side assembly groove 30 is set on the left side or the right side of the main wall part 1. Of course, it can be set on both the left and right sides, so that the design is based on actual user needs, or based on some installation effects, such as lighting effects.

[0051] The specific design of the side light strip assembly groove 30 is as follows: the main body of the side assembly groove 30 is rectangular and the part close to the side opening 301 is arc-shaped. The side opening 301 on the three-dimensional expanded side support wall 3 on the right side of the main wall part 1 is on the right side of the side assembly groove 30 connected thereto and is in the middle of the front and back of the side assembly groove 30. The side opening 301 on the three-dimensional expanded side support wall 3 on the left side of the main wall part 1 is on the left side of the side assembly groove 30 connected thereto and is in the middle of the front and back of the side assembly groove 30. The front and back length of the side assembly groove 30 is greater than the front and back length of the side opening 301. Here, the rectangular main body and the arc-shaped arched part of the side assembly groove 30 are connected left and right. Such a design is suitable for some lamp structures on curved surfaces, etc., and the lighting effect is relatively good. Of course, the side assembly groove 30 can also be completely rectangular, or C-shaped with the opening facing left or right. Like the aforementioned design, the outer side of a side assembly groove 30 requires two side limiting walls c spaced front and back to form a relatively regular structure of the side assembly groove 30 and the side opening 301, and it is basically symmetrical front and back, and the side limiting wall c itself is also a relatively regular design.

[0052] Some proportional parameters of the above-mentioned estimated regular structure can refer to the following settings: the left and right wall thickness of the three-dimensional expansion side support wall 3 without the side assembly groove 30 is 0.3 to 0.6 of the left and right wall thickness of the three-dimensional expansion side support wall 3 with the side assembly groove 30, the left and right width of the side assembly groove 30 is 0.3 to 0.5 of the left and right wall thickness of the three-dimensional expansion side support wall 3, the left and right width of the side opening 301 is 0.25-0.4 of the left and right width of the side assembly groove 30, the front and rear thickness of the suspended wall part 4 is 0.8-1.2 of the front and rear thickness of the rear reinforced connection wall part 6, and the front and rear thickness of the secondary connection base wall part 2 is The front and rear thickness of the connecting wall part 6 is 0.6-1, the front and rear width of the three-dimensional expansion side support wall 3 is 0.6-1 of the left and right width of the floating wall part 4, the front and rear width of the three-dimensional expansion side support wall 3 is 0.6-1 of the left and right width of the rear reinforcement connecting wall part 6, the left and right width of the secondary connecting basic wall part 2 is 0.4-0.6 of the left and right width of the rear reinforcement connecting wall part 6, the front and rear width of the side assembly groove 30 is 0.4-0.6 of the front and rear width of the three-dimensional expansion side support wall 3, the front and rear width of the side opening 301 is 0.45-0.7 of the front and rear width of the side assembly groove 30, and the floating wall part in the same main wall part 1 is 0.6-1 of the left and right width of the rear reinforcement connecting wall part 6. 4 and the rear reinforcement connecting wall part 6 is 8-18mm, and the maximum distance between the left and right two three-dimensional expansion side support walls 3 in the same main wall part 1 is 18-30mm. For example, the left and right wall thickness of the three-dimensional expansion side support wall 3 without the side assembly groove 30 is 3.63mm, and the left and right wall thickness of the three-dimensional expansion side support wall 3 with the side assembly groove 30 is 7.07mm. The left and right width of the side assembly groove 30 is 2.79mm, the upper and lower width of the side assembly groove 30 is 11mm, the left and right width of the side opening 301 is 0.94mm, and the upper and lower width of the side opening 301 is 6.57mm. The suspended wall part The front-to-back thickness of the suspended wall portion 4 and the rear reinforced connecting wall portion 6 are both 3.7mm, the front-to-back thickness of the secondary connecting foundation wall portion 2 is 3mm, the maximum spacing between the suspended wall portion 4 and the rear reinforced connecting wall portion 6 in the same main wall portion 1 is preferably 13.1mm, the maximum spacing between the left and right three-dimensional expansion side support walls 3 in the same main wall portion 1 is preferably 24.81mm, the front-to-back width of the three-dimensional expansion side support wall 3 is 20.5mm, the left and right widths of the suspended wall portion 4 and the left and right widths of the rear reinforced connecting wall portion 6 are 24.81mm, and the left and right widths of the secondary connecting foundation wall portion 2 are 13.09mm. These dimensions mainly involve the dimensions of the left and right middle structures of the profile. The left and right sides of the plug-in parts will have slight shape deformation, which can be adjusted appropriately. The main purpose is to ensure that the dimensions of the middle structure are designed reasonably.

[0053] However, the side assembly groove 30 can also be a special-shaped groove body, and the side limiting wall c can be only one, so that it is easy to form a special-shaped groove. For example, the three-dimensional expansion side support wall 3 extends to the right to form an arc-shaped or inclined outward expansion plate w, and the outward expansion plate w is connected to the side limiting wall c extending in the direction of the three-dimensional expansion side support wall 3 at one end away from the three-dimensional expansion side support wall 3, so that a barbed groove can be formed. In this way, this concealed groove can be used to install other workpieces. In addition, the floating wall part 4 can be a straight-line flat plate or a curved plate that arches forward. In addition, a side assembly groove 30 can be formed on a single three-dimensional expansion side support wall 3, or more side assembly grooves 30 can be formed spaced apart from each other in the front and back. Of course, they are all equipped with a side opening 301 and a side limiting wall c.

[0054] Preferably, the portion where the secondary connecting base wall portion 2 is integrally connected to the three-dimensional expansion side support wall 3 is also integrally connected with a support reinforcement wall 7 extending backward. The front-to-back length of the support reinforcement wall 7 is less than the front-to-back length of the three-dimensional expansion side support wall 3. The support reinforcement wall 7 enhances the strength of the rear side and ensures the stability of the entire structure. The front-to-back length of the support reinforcement wall 7 is preferably no more than half of the front-to-back length of the three-dimensional expansion side support wall 3. Generally, the front-to-back length of the support reinforcement wall 7 is selected to be one-quarter to one-third of the front-to-back length of the three-dimensional expansion side support wall 3. The above design is mainly for single-sided walls, and the front-to-back width of the support reinforcement wall 7 is 4.5mm.

[0055] Then the next is the second type, the secondary connecting basic wall part 2 is in a straight line shape and is located in the middle of the front and back of the main wall part 1, at least one three-dimensional expansion side support wall 3 is located in the front part of the secondary connecting basic wall part 2 and has a side assembly groove 30, at least one three-dimensional expansion side support wall 3 is located in the rear part of the secondary connecting basic wall part 2 and has a side assembly groove 30. This structure is suitable for double-sided facade use, that is, the secondary connecting basic wall part 2 divides the main wall part 1 into two halves, front and back. In fact, the secondary connecting basic wall part 2 divides the three-dimensional expansion side support wall 3 into two halves, front and back, and the end of the secondary connecting basic wall part 2 is integrally connected to the front and back middle position of the outer wall of the three-dimensional expansion side support wall 3. Then, the side assembly grooves 30 can be set on the front or rear wall of the three-dimensional expansion side support wall 3, or the side assembly grooves 30 can be set separately, and more than one side assembly groove 30 can be set on the front or rear wall. Of course, it is also necessary to be equipped with side openings 301 and side limiting walls c, and these structures can follow the structural design of the previous single wall. In this structure, for example, the front side is a floating wall part 4, then the rear reinforced connecting wall part 6 on the rear side is actually used as the floating wall part 4 on the rear side. In this way, parts of the main wall part 1 exist on the front and back sides, and there are floating wall structures on the front and back sides, which can be used on both sides and are very suitable for use as walls, fences, etc. In this structure, the male plug-in wall part 52 and the female plug-in wall part 51 are both arranged in the middle front and back position of the main wall part 1. For example, the male plug-in wall part 52 is integrally connected to the middle front and back position of the leftmost three-dimensional expansion side support wall 3, and the female plug-in wall part 51 is integrally connected to the middle front and back position of the rightmost three-dimensional expansion side support wall 3. Since it is to be used on both sides here, there is no further fixed structure on the front or rear side. Generally, after splicing, it is further fixed to the building structure on the leftmost and rightmost sides. The front and rear sides are at most supported by some support frames at the bottom, etc. Then the splicing here is simply to plug in the left and right, then the male plug-in wall part 52 can be a straight-line plate and the head of one end deviating from the three-dimensional expansion side support wall 3 is a shape similar to a bullet head, and the female plug-in wall part 51 can also be straight-line and rectangular, and the front and back middle part of the female plug-in wall part 51 forms an opening facing left or right to match the male plug-in wall part 52.

[0056] On the basis of the above two profile structure design schemes, it can be further updated. The surfaces of the main wall part 1, the secondary connecting foundation wall part 2 and the suspended wall part 4 are covered with a layer of integrally connected plastic protective film s. The part of the plastic protective film s located on the surface of the suspended wall part 4 is a brushed film. The plastic protective film s is a separate layer of plastic film without wood components. Because the wood-plastic board has wood components, it is still easy to absorb moisture, which leads to changes in performance, especially in very humid conditions. Therefore, on the one hand, the plastic protective film s plays a role in structural peripheral protection. On the other hand, it improves the waterproof performance of the wood-plastic board itself. This is particularly suitable for use in humid environments. The part of the plastic protective film s located on the surface of the suspended wall part 4 is a brushed film. Artificial texture is formed on the plastic protective film s through existing equipment such as drawing rollers, making it look like wood grain. The main purpose is to improve the aesthetics of the profile. Of course, if it is used as a non-facade floor, it also has a certain anti-slip ability. Furthermore, by applying the wire drawing to the plastic protective film, there's no need to apply wire drawing to the WPC board, which would damage the board's surface structure. This prevents performance degradation caused by surface damage. Because the WPC board's surface is primarily composed of plastic, wire drawing exposes the wood component, making it more susceptible to moisture. Therefore, the above design offers enhanced protection. Furthermore, plastic materials are easier to control for light reflection, including effects such as glazing. By varying the composition, different desired effects can be achieved. The plastic protective film can be applied to the exterior surface of the WPC profile after it has been formed. More preferably, the protective film is extruded from liquid plastic around the WPC board while the WPC board is being extruded into the profile. While the extrusion equipment used for both is different, they can be installed together. Alternatively, other companies can also implement the above structure. The plastic protective film should be as thin as possible, such as 0.5 mm.

[0057] Furthermore, at least one of the three-dimensional expansion side support walls 3 and / or at least one of the suspended wall parts 4 is coated with a fluorescent layer y that can absorb light and then emit light. Some existing fluorescent materials can store light after absorbing it and then automatically emit light in a dark environment. Therefore, this fluorescent layer can absorb light during the day or when the light bar is on, and can still emit light when it is dark or when the light bar is turned off, making the profile more controllable to light and saving energy. The fluorescent layer can actually be the aforementioned plastic protective film s. A fluorescent layer can be formed by adding a fluorescent component to the plastic protective film s. Of course, the fluorescent layer can also be applied separately. For example, if the wood-plastic board does not have a plastic protective film s, a fluorescent layer can be applied separately, and a fluorescent layer can also be applied on top of the plastic protective film s. This separate fluorescent layer can be a thin film made of existing materials.

[0058] Through the structural design of the above profiles, the performance of the profiles themselves and the effect of use are greatly improved, which has a major breakthrough in economic and social benefits.

[0059] Example 2, as Figure 13 、 14 As shown, a lighting system includes at least one piece of the wood-plastic profile described in Example 1, wherein at least one of the side assembly grooves 30 is installed with a light strip d. The characteristic of this embodiment is that based on the profile of Example 1, a self-formed lighting system for the vertical wall is formed through on-site installation. This lighting system integrates the two functions of wall and lighting, that is, the light strip is installed in the side assembly groove 30.

[0060] Furthermore, the light strip d is a flexible light strip, inserted into at least two side mounting grooves 30 of a wood-plastic profile. The light strip d is a conventional flexible, bendable, waterproof light strip, which not only provides a lighting effect but also has the effect of connecting the profiles in series. This description only involves inserting one such light strip into two or more side mounting grooves 30 of a wood-plastic profile. Of course, different profiles can also be inserted into the grooves for connection. That is, at least one light strip d is continuously inserted into the side mounting grooves 30 of at least two mutually joined wood-plastic profiles. This not only effectively achieves lighting, but also provides structural connection and overall structural stability. Of course, due to the different slot positions, since the light strip typically emits light from one side, it is necessary to bend at the upper or lower end when the light strip is inserted in a circuitous manner, and also to twist at the bend position. This is to ensure that the light strip's light output side is close to the outer exit of the side mounting groove 30, that is, close to the side opening 301. Then the end of the light strip is a wire, and this end can finally be connected to the upper slot or lower slot of the side assembly groove 30, that is, the wire can be connected to the corresponding power supply or other electrical equipment on the upper or lower side. Of course, the light strip can be more particular about the present application, and the light-emitting surface can be continuously changed from the front. For example, the first section is inserted into a side assembly groove 30 and is front-emitting. The next one is used as a transition section for bending. The transition section does not need to be provided with a light-emitting lamp. Then the next section is the reverse light-emitting section. In this way, during the series connection process, one side of the light-emitting surface can always be facing the side opening 301 according to actual needs. In this way, there is no need for a screwing operation, and the stability of the structure will be better. Of course, the different designs of the light-emitting side can be continuously changed, or according to actual needs, the light body can be set on the side where the light-emitting surface needs to be changed.

[0061] The installation of the above structure can be that the profiles are first plugged in from left to right in sequence for splicing, and then the light strips are passed through the upper and lower winding paths, and finally the wiring is performed. If it is a single-sided profile, then during the splicing process, each profile also needs to be further positioned and fixed to the inner wall through locking parts. Of course, the left and right sides also need to be further installed and fixed to some building keels on the side. These are existing conventional designs and will not be repeated here.

[0062] However, since the profile of this application is provided with a light bar, some protection is actually required, especially on the upper and lower sides, to prevent the light bar from being exposed on the upper or lower side of the side assembly groove 30. At the same time, in order to prevent rainwater from entering, some protection is required. It is necessary to provide cover plates g on the upper and lower sides to cover the upper and lower notches of the upper and lower side assembly grooves 30 and the light bar. The cover plates g can be L-shaped plates or U-shaped plates and can be covered on the upper and lower sides. Of course, the left and right sides of the cover plates g need to be further connected and fixed with the building keels on the side, etc., and it is also necessary to ensure that the cover plates g do not squeeze the light bar too tightly, otherwise the light bar will be crushed. Alternatively, a rectangular plate can be used, and a raised structure can be formed on the plate surface. The raised structure can be inserted into the through hole t to ensure the stability of the connection. Of course, some recesses and exits can be formed on the lower side of the rectangular plate for the upper or lower part of the light bar to be placed in and the wires to be led out.

[0063] In addition, the two profiles are not only spliced together on the left and right sides by plugging the male and female parts into the wall, because sometimes the profile height will be designed to be shorter according to transportation requirements. At this time, in order to meet the requirements of the facade height, the profiles also need to be butt-connected between the upper and lower parts. Since the profiles of the present application are formed by extrusion, the upper and lower parts are relatively flat, so they can be stacked up and down for connection. The stacking position can be connected by applying glue, or the connection can be reinforced by external plate locking parts. Of course, these further strengthening connection structures are not necessarily required. For example, the aforementioned single-sided profiles, then since they can strengthen the positioning between themselves and the building, the upper and lower splicing of this type of profile does not require further strengthening of the connection at the stacking position, but only needs to be supported up and down. In addition, there will be external strengthening connection structures such as keels on the left and right sides of the buildings themselves. So for double-sided profiles, there is no big problem in further strengthening the left and right sides after stacking up and down, and it is easy to achieve.

[0064] In this way, the wall formed by a single profile or multiple profiles is better integrated through the light strips, forming a high-quality lighting facade system, which is very suitable for use in today's society and has made great contributions to cost control, social and economic benefits, etc.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
