referring to fig. 1-3, the present embodiment provides a wallboard external corner installation structure, which includes a connecting member, a wallboard 1 and an external corner bending plate 2. The board 2 that bends of external corner is the L type board of bending, and wallboard 1 is dull and stereotyped, and wherein 1 quantity of wallboard has two, and 1 mutually perpendicular of two wallboards is and be located two edges of the board 2 that bends of external corner respectively, and this is prior art, and this embodiment is no longer repeated.

The two wall panels 1 are identical in structure, and one wall panel 1 is illustrated in the embodiment. The edge of wallboard 1 is provided with first draw-in groove 11, owing to need not be at the fixed cardboard in wallboard 1's edge, therefore wallboard 1's width has obtained the reduction compared prior art, carries more easily, also is difficult impaired in handling. The edge of the external corner bending plate 2 is provided with a second clamping groove 21. The first clamping groove 11 and the second clamping groove 21 are matched with a connecting piece to complete connection of the wallboard 1 and the external corner bending plate 2.

Specifically, the connecting piece includes joint board 3, attaching plate 4 and connecting plate 5, and the both sides edge of connecting plate 5 is fixed respectively at the back of joint board 3 and attaching plate 4's front, and joint board 3 and attaching plate 4 realize the connection process through connecting plate 5. The width of the connecting piece is small, so that the connecting piece is convenient to transport on site and assemble on a decoration site, and the wallboard 1 and the external corner bending plate 2 are connected. In addition, the connecting piece is small in size, so that the production cost is low, the decoration cost cannot be greatly influenced even if the connecting piece is damaged, and meanwhile, the connecting piece simultaneously keeps a split structure with the wallboard 1 and the external corner bending plate 2, so that the wallboard 1 and the external corner bending plate 2 do not need to be replaced synchronously under the condition that the connecting piece is damaged and used.

The right side edge of joint board 3 passes through the deformation joint in first draw-in groove 11, and the left side edge of joint board 3 passes through the deformation joint in second draw-in groove 21 to this has accomplished wallboard 1 and the connection of external corner board 2 of bending. On this basis, the front of attaching plate 4 is pressed simultaneously and is bent the medial surface of board 2 at the back of wallboard 1 and external corner, and under the effect of connecting plate 5, joint board 3 and attaching plate 4 are bent wallboard 1 and external corner simultaneously and are bent board 2 and embrace tightly to the joint strength of wallboard 1 and external corner board 2 has been promoted to the connecting piece. In addition, the attaching plate 4 also promotes the contact area of the connecting piece with the wallboard 1 and the external corner bending plate 2, so that the connection stability of the wallboard 1 and the external corner bending plate 2 is effectively promoted.

Because there is fossil fragments 8 between this embodiment attaching plate 4 and the wall 7, consequently great space has between external corner board 2 and the wall 7 corner of bending. However, in other embodiments, if there is no keel 8, the external corner bending plate 2 is very close to the corner of the wall surface 7, and even interacts with the corner part of the wall surface 7, in order to avoid this, the inner side surface of the bending part of the external corner bending plate 2 is concave to form the avoiding groove 23, and the avoiding groove 23 avoids the corner of the wall surface 7, so as to increase the application condition of the external corner mounting structure of the wall panel.

After the wallboard 1 and the external corner bending plate 2 are assembled through the connecting piece, the connecting plate 5 is positioned between the edge of the wallboard 1 and the edge of the external corner bending plate 2.

Preferably, the edge of the board 2 that bends of external corner and the edge of wallboard 1 paste respectively at the two sides of connecting plate 5 to this reduces the external corner and bends the interval between 2 edges of board and wallboard 1 edge, and realizes through connecting plate 5 that the external corner bends board 2, mutual location between connecting piece and the 1 three of wallboard, with this ensure 3 both sides edges of joint board can fully get into first draw-in groove 11 and second draw-in groove 21, ensure that joint board 3 fully plays the joint effect.

Use second draw-in groove 21 as an example, if joint board 3 gets into second draw-in groove 21 in-process and second draw-in groove 21 inner wall between be surface contact, then joint board 3 can receive too big resistance because of the deformation degree is too big, not only is unfavorable for joint board 3's joint process, causes too big damage and the damage of connecting piece to second draw-in groove 21 inner wall easily moreover.

In order to effectively avoid this problem, the back of joint board 3 is backward the protrusion and is formed first joint rib 31 and second joint rib 32 respectively, and first joint rib 31 is pressed on 11 inner walls of first draw-in groove to leave the clearance between the back of

joint board

3 and 11 inner walls of first draw-in groove, and second joint rib 32 is pressed on 21 inner walls of second draw-in groove to leave the clearance between the back of joint board 3 and the 21 inner walls of second draw-in groove. The contact area of the inner wall of the first clamping groove 11 and the inner wall of the second clamping groove 21 and the clamping plate 3 is reduced through the first clamping rib 31 and the second clamping rib 32, so that the clamping plate 3 is in line contact with the inner wall of the first clamping groove 11 and the inner wall of the second clamping groove 21 in the clamping process, too large resistance is prevented from being applied to the clamping plate 3 in the clamping process, and the clamping process of the clamping plate 3 is more smooth.

On this basis, all leave the space between the positive and the first draw-in groove 11 inner wall of joint board 3 to and between the positive and the second draw-in groove 21 inner wall of joint board 3, in order to ensure that first draw-in groove 11 and second draw-in groove 21 have sufficient space to supply joint board 3 to deform.
