[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] like Figure 1-2As shown, an outdoor wood-plastic co-extruded wallboard includes a plurality of wallboard units 100 and a plurality of connectors. Adjacent wallboard units 100 are connected by the connectors. When the wallboard units 100 are connected to the connectors, a gap is left between their end faces and the connectors.

[0035] The wall panel unit 100 includes a base plate 101 and a panel 102. The panel 102 is fixedly connected to the base plate 101 and has an arched structure. The wall panel unit 100 also includes a plurality of support rods 103. The support rods 103 are arranged between the base plate 101 and the panel 102. The arched structure of the panel 102 and the support rods 103 are used to improve the structural strength of the wall panel unit 100. At the same time, the arched structure of the panel 102 is used to increase the aesthetics of the wall panel unit 100 after laying, thereby ensuring the reliability of the wall panel.

[0036] Furthermore, a connecting block 105 is provided at one end of the panel 102, and a connecting groove 104 is provided at the other end. A second groove 107 is provided at the bottom of the connecting block 105. The length of the connecting block 105 is greater than the depth of the connecting groove 104, and the height of the connecting block 105 is less than the height of the connecting groove 104. The two adjacent wall panel units 100 are connected through the cooperation of the connecting block 105 and the connecting groove 104.

[0037] A first elastic arc piece 106 is provided at one end of the connecting block 105 . When the connecting block 105 is inserted into the connecting groove 104 , the first elastic arc piece 106 abuts against the inner wall of the connecting groove 104 .

[0038] By setting the first elastic arc piece 106, the length of the connecting block 105 inserted into the connecting groove 104 is positioned, so that a gap is left between the connecting block 105 and the inner wall of the connecting groove 104 for the wall panel unit 100 to expand due to heat, thereby avoiding mutual squeezing and damage between adjacent wall panel units 100; the first elastic arc piece 106 can position the position of the connecting block 105 inserted into the connecting groove 104 without hindering the lateral expansion of the wall panel unit 100, making the connection of the wall panel unit 100 more convenient.

[0039] Furthermore, the connecting member includes a first horizontal section 201, a second horizontal section 202 and a vertical section 203, and the first horizontal section 201 and the second horizontal section 202 are connected by the vertical section 203; the length of the first horizontal section 201 is greater than the length of the second horizontal section 202, and the height of the vertical section 203 corresponds to the height of the bottom plate 101; the height of the second horizontal section 202 corresponds to the height of the second groove 107; when the two wall panel units 100 are connected, one end of the second horizontal section 202 is in the connecting groove 104, and the other end is in the second groove 107, the first horizontal section 201 is at the bottom of the bottom plate 101, and one end of the second horizontal section 202 is in the second groove 107. There is a gap between the inner wall of the connecting groove 104 and the other end and the inner wall of the second groove 107; a first groove is provided on the first horizontal section 201, and a plurality of threaded holes are provided in the first groove for connecting screws 400. The first horizontal section 201 is fixed to the wall with the screws 400. The first groove is used to accommodate the end plate of the screw 400 to prevent the top of the screw 400 from protruding from the surface of the first horizontal section 201; second elastic arc pieces 204 are respectively provided on the side walls of both sides of the vertical section 203; when the two wall panel units 100 are connected, the two second elastic arc pieces 204 respectively rest on the end faces of the bottom plates 101 of the two wall panel units 100.

[0040] The second arc-shaped spring piece is used to position the two mutually connected wall panel units 100 so that a gap is left when the connecting piece is connected to the wall panel unit 100, thereby reserving space for thermal expansion of the wall panel unit 100.

[0041] like Figure 3-4 As shown, as a further preferred embodiment of the present application, the connecting member includes a first connecting plate 301, a second connecting plate 302, a third connecting plate 304, a first splint 303 and a second splint 306, the second connecting plate 302 and the third connecting plate 304 are fixedly connected to the first connecting plate 301, the second connecting plate 302 and the third connecting plate 304 are arranged in parallel, and the second connecting plate 302 is arranged perpendicular to the first connecting plate 301; a gap is left between the second connecting plate 302 and the third connecting plate 304, the first splint 303 is arranged at the top of the second connecting plate 302, the second splint 306 is arranged at the top of the third connecting plate 304, the distance between the second connecting plate 302 and the first connecting plate 301 corresponds to the bottom plate 101, and the distance between the third connecting plate 304 and the first connecting plate 301 corresponds to the bottom plate 101.

[0042] A first positioning groove 3021 is provided on the second connecting plate 302 , and a second positioning groove is provided on the third connecting plate 304 . Support arc pieces 305 are provided in the first positioning groove 3021 and the second positioning groove. Two protrusions 3051 are provided on the support arc piece 305 , and the two protrusions 3051 are symmetrically arranged.

[0043] When the connecting piece connects two wall panel units 100, the first clamping plate 303 is in the second groove 107, the second clamping plate 306 is in the connecting groove 104, the first connecting plate 301 is at the bottom of the base plate 101, the second connecting plate 302 is against one end of the base plate 101 of one wall panel unit 100, and the third connecting plate 304 is against one end of the base plate 101 of the other wall panel unit 100. The second connecting plate 302 and the third connecting plate 304 are used to directly locate the connection position of the two wall panels; the gap between the second connecting plate 302 and the third connecting plate 304 is used to reserve space for the expansion of the two wall panel units 100 to avoid the two wall panel units 100 being squeezed against each other; the setting of the supporting arc plate 305 enhances the supporting force of the second connecting plate 302 and the third connecting plate 304 to avoid the two wall panel units 100 pushing the second connecting plate 302 and the third connecting plate 304 to move when the two wall panel units 100 are connected.

[0044] When installing the support arc piece 305, the two protrusions 3051 are squeezed relative to each other to cause the support arc piece 305 to shrink and deform, reducing the lateral opening of the support arc piece 305, and pushing the support arc piece 305 between the second connecting plate 302 and the third connecting plate 304, so that the two ends of the support arc piece 305 are respectively inserted into the first positioning groove 3021 and the second positioning groove, completing the installation of the support arc piece 305.

[0045] The above descriptions are merely some preferred embodiments of the present disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed herein is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also encompass other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
