Description

Technical Field

[0001] The utility model belongs to the technical field of wall panels, and particularly relates to a multi-purpose co-extruded wood-plastic wall panel and fence. Background Art

[0002] Wood-plastic wall panels and fences are one of the most important products in the field of wood-plastic composite materials, and there is a rich variety. However, the current wood-plastic wall panels and fences have a single structure, and products of the same specification (wall panels or fence panels) cannot be used interchangeably. Wall panels can only be installed on the wall, and fence panels can only be installed as fences, resulting in the need to produce different wall panel or fence molds for products with the same installation effect. The above situation leads to a large number of wall panel or fence specifications in wood-plastic enterprises, high investment and production costs, and is not conducive to intensive and large-scale production. Content of the Utility Model

[0003] In order to make up for the deficiencies of the prior art, the utility model provides a multi-purpose co-extruded wood-plastic wall panel and fence, which can achieve multiple different installation effects for products of the same specification, so as to solve technical problems such as single color and single installation effect.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] In the first aspect, a multi-purpose co-extruded wood-plastic wall panel includes a wall panel main body. The head and tail sections of the wall panel main body are respectively a plug-in part and a slot part that is in plug-in fit with the plug-in part. A tenon is provided on the plug-in part. A slot that matches the tenon is provided on the slot part.

[0006] Screw grooves and nail grooves are respectively formed on the tenon and the inner wall of the slot. The orientations of the screw grooves and the nail grooves are opposite. First co-extruded layers and second co-extruded layers are respectively provided on both side surfaces of the wall panel main body.

[0007] Further, tapered limiting teeth are provided on both side walls of the slot.

[0008] Further, an integrally formed limiting frame is provided on the slot part. The limiting frame is L-shaped. A slot that matches the tenon is formed between the inner side surface of the limiting frame and the end surface of the wall panel main body.

[0009] Further, the screw groove is divided into a guiding groove at the inner end and a limiting groove at the outer end. The width of the limiting groove is greater than that of the guiding groove.

[0010] Further, the wall panel main body includes a plurality of Great Wall piers connected end to end in sequence, and the head and tail sections are respectively a plug-in part and a slot part.

[0011] In the second aspect, a fence includes an upper cross beam, a lower cross beam, two columns and a plurality of wall panel main bodies. The wall panel main body adopts the wall panel main body as described in the first aspect.

[0012] Each of the wall panel bodies is connected by sequentially plugging the head and tail. The upper cross beam and the lower cross beam are respectively fixed at the top and bottom of each wall panel body. The two ends of the upper cross beam and the two ends of the lower cross beam are respectively fixed to two columns.

[0013] Furthermore, the upper cross beam and the lower cross beam are both provided with limiting grooves. The top and bottom of each wall panel body are respectively embedded and fixed in the limiting grooves of the upper cross beam and the lower cross beam. Installation grooves are provided on the opposite side surfaces of the two columns. The two ends of the upper cross beam and the two ends of the lower cross beam are both embedded in the installation grooves of the two columns.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The utility model can realize that the same specification product can be installed on the wall as a wall panel or installed as a fence as a fence panel. When used as a wall panel, both the front and back sides can be installed and used, realizing a free choice.

[0016] 2. The utility model respectively sets a first co-extrusion layer and a second co-extrusion layer on the two side surfaces of the wall panel body. Different colors can be realized for the first co-extrusion layer, the second co-extrusion layer, and the core layer. At the same time, screw grooves and nail grooves are respectively provided on the inner walls of the tenon and the slot, and the directions are opposite. When the first co-extrusion layer or the second co-extrusion layer faces the outside, the user can drive screws or nails in the corresponding screw grooves or nail grooves to complete the fixation of the wall panel body. By using different colors for the first co-extrusion layer, the second co-extrusion layer, and the core layer, the customer can choose the color exposed to the outside according to their own preferences, so that the wall panel body has a variety of colors and can meet the needs of more customers.

[0017] 2. The utility model sets tapered limiting teeth on the two side walls of the slot. When the tenon on the wall panel body is inserted into the slot, it can be guided by the two limiting teeth, so that the tenon can quickly and centrally enter the slot. At the same time, the setting of the limiting teeth reserves an expansion gap for the tenon in the slot. When the tenon expands due to heat or water absorption, it will break through the limiting teeth and enter the reserved expansion gap, thereby avoiding the deformation of the slot part of the wall panel body caused by the lack of expansion gap.

[0027] The present utility model will be further described below with reference to the drawings.

[0028] Embodiment 1

[0029] As Figure 1 and 2 shown, a multi-purpose co-extruded wood-plastic wall panel includes a wall panel main body 1. The wall panel main body 1 includes a plurality of Great Wall piers connected end to end in sequence, and the head and tail sections are respectively an insertion part 1-1 and a slot part 1-2 that is inserted and matched with the insertion part 1-1. During installation, between two adjacent wall panel main bodies 1, the insertion part 1-1 on one wall panel main body 1 is inserted and matched with the slot part 1-2 on the other wall panel main body 1 to realize the connection of the two wall panel main bodies 1.

[0030] The specific structure is that a tenon 2 is provided on the insertion part 1-1. A limiting frame 3 formed integrally is provided on the slot part 1-2. The limiting frame 3 is L-shaped, and a slot matching with the tenon 2 is formed between the inner side surface and the end surface of the wall panel main body 1. During installation, the tenons 2 of adjacent wall panel main bodies 1 are inserted into the corresponding slots, thereby realizing the connection between two wall panel main bodies 1.

[0031] Furthermore, tapered limiting teeth 4 are provided on both side walls of the slot. When the tenon 2 on the wall panel main body 1 is inserted into the slot, it is guided by the two limiting teeth 4, so that the tenon 2 can quickly and centrally enter the slot. At the same time, the setting of the limiting teeth 4 reserves an expansion gap for the tenon 2 in the slot. When the tenon 2 expands due to heat or water absorption, it will break through the limiting teeth 4 and enter the reserved expansion gap, thereby avoiding the deformation of the slot part 1-2 of the wall panel main body 1 caused by the lack of expansion gap.

[0032] As Figure 2 and 3 shown, a first co-extruded layer 5 and a second co-extruded layer 6 are respectively provided on both side surfaces of the wall panel main body 1. The wall panel main body 1 is the core layer. The core layer, the first co-extruded layer 5 and the second co-extruded layer 6 all adopt different colors, and customers can face the first co-extruded layer 5 or the second co-extruded layer 6 to the outside according to their own preferences.

[0033] Furthermore, a screw groove 7 and a pneumatic nail groove 8 are respectively formed on the tenon 2 and the limiting frame 3. Among them, the screw groove 7 is divided into a guiding groove at the inner end and a limiting groove at the outer end. The width of the limiting groove is greater than that of the guiding groove, which is used to adapt to the size of the tail end of the screwed-in screw and prevent the tail end of the screw from being exposed outside the wall panel main body 1, affecting the appearance of the wall panel main body 1.

[0034] As Figure 4 shown, when the user chooses to use the first co-extruded layer 5 as the exposed wall surface for front installation, the screw groove 7 faces the outside, and the user drives a screw into the screw groove 7. When the screw is driven in, the head of the screw is guided and positioned through the guiding groove. After the screw is completely driven in, the tail end of the screw sinks into the limiting groove, ensuring the appearance of the surface of the wall panel main body 1. The driving in of the screw realizes the fixing of the wall panel main body 1 with the first co-extruded layer 5 as the exposed surface on the wall.

[0035] As Figure 5 shown, when the user chooses to use the second co-extruded layer 6 as the exposed wall surface for reverse installation, the pneumatic nail groove 8 faces the outside, and the user drives a pneumatic nail into the pneumatic nail groove 8. After the pneumatic nail is completely driven in, the tail end is completely sunk into the pneumatic nail groove 8, ensuring the appearance of the wall panel main body 1 while realizing the fixing of the wall panel main body 1 with the second co-extruded layer 6 as the exposed surface on the wall.

[0036] Embodiment 2

[0037] As shown Figure 6 in the figure, a fence includes an upper cross beam 9, a lower cross beam 10, two columns 11 and multiple wall panel bodies 1. Among them, the wall panel body 1 adopts the wall panel body 1 described in Embodiment 1. Each wall panel body 1 is connected by sequentially plugging the head and tail. The upper cross beam 9 and the lower cross beam 10 are respectively installed at the top and bottom of each wall panel body 1 to define the relative positions of each wall panel body 1 in the vertical direction. Both ends of the upper cross beam 9 and both ends of the lower cross beam 10 are fixed to the two columns 11 respectively.

[0038] The specific structure is, as shown Figure 6 in 7 the figure, both the upper cross beam 9 and the lower cross beam 10 are provided with limiting grooves. The top and bottom of each wall panel body 1 are respectively embedded and fixed in the limiting grooves of the upper cross beam 9 and the lower cross beam 10. Installation grooves are provided on the opposite side surfaces of the two columns 11. Both ends of the upper cross beam 9 and both ends of the lower cross beam 10 are embedded in the installation grooves of the two columns 11.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
