Specifically, the inside corner fastener 3 may be fixed to the wall surface 4 by a fastener, for example, a self-tapping screw is used to fix the inside corner fastener 3 to the wall surface 4 in fig. 1. Alternatively, the inside corner fixing member 3 may be fixed to the wall surface 4 by means of gluing, for example, by fixing the inside corner fixing member 3 to the wall surface 4 using a structural adhesive, which is not limited in the embodiment of the present disclosure.

According to the wallboard internal corner fixing structure, the first wallboard 1 and the second wallboard 2 are respectively fixed on the wall surface 4 at the internal corner position through the internal corner fixing piece 3, and the first wallboard 1 and the second wallboard 2 are connected with the internal corner fixing piece 3 in an inserting mode, so that the wallboard internal corner fixing structure is convenient to install and easy to operate; after the wallboard is fixed, in the seam between first wallboard 1 and second wallboard 2, socket joint recess 31's second groove lateral wall 312 is arranged, can play the decorative joint effect to the height of second groove lateral wall 312 does not exceed the thickness of second wallboard 2, and second groove lateral wall 312 can not bulge the surface of wallboard like this, thereby can not be to skirting line and the apex angle line installation conflict of wallboard, reduced skirting line and apex angle line the degree of difficulty of wallboard reentrant corner installation.

As shown in fig. 1 and 2, the second wall plate 2 is prefabricated with a plugging groove 21 on the side end surface of the female corner side, and the plugging groove 21 is matched with the plugging protrusion 32. When the second wall plate 2 is mounted on the female angle fixing member 3 by the engagement of the insertion groove 21 with the insertion protrusion 32, the second wall plate 2 can be restrained from moving in the thickness direction, and the second wall plate 2 can be firmly fixed to the wall surface 4. Also, when the first wall plate 1 is mounted in the socket groove 31, the first wall plate 1 can be restrained from moving in the thickness direction, and the first wall plate 1 can be firmly fixed to the wall surface 4. Therefore, the first wallboard 1, the second wallboard 2 and the internal corner fixing piece 3 are inserted and installed mutually more firmly, the wallboard cannot deform even if slightly sinking, and the deformation resistance is strong.

In one embodiment, in the above-mentioned wallboard internal corner fixing structure, referring to fig. 3, the groove bottom wall 313 extends in the width direction to form the fixing base plate 33, the fixing base plate 33 is parallel to and spaced from the plugging protrusion 32, and the fixing base plate 33 can abut against the wall surface 4 and be fixedly connected with the wall surface 4 by a fastener. During installation, only the fixed bottom plate 33 is required to be abutted against the wall surface 4 on one side of the internal corner, then the internal corner fixing piece 3 is moved to the wall surface 4 on the other side of the internal corner, the internal corner fixing piece 3 can be abutted against the wall surfaces 4 on two sides of the internal corner rapidly, and then the internal corner fixing piece 3 is fixedly connected to the wall surface 4 at the position of the fixed bottom plate 33 by using a fastener, so that the internal corner fixing piece 3 can be installed rapidly at the internal corner.

In one embodiment, referring to fig. 3, the fixing base plate 33 is provided with a countersunk nail groove 331 on a side facing away from the wall surface 4, the groove bottom wall 313 is provided with a first supporting protrusion 34 on a side facing the wall surface 4, the first supporting protrusion 34 is located at one end of the groove bottom wall 313 in the width direction, and the top end of the first supporting protrusion 34 is flush with the outer bottom wall of the countersunk nail groove 331.

When the female angle fixing member 3 is fixed using a fastener such as the self-tapping screw described above, the nut of the self-tapping screw can be hidden in the countersunk nail groove 331, avoiding the nut protruding to the second wall plate 2. In addition, the first supporting protrusion 34 and the outer bottom wall of the nail sinking groove 331 are abutted against the wall surface 4 together, so that the contact surface with the wall surface 4 is increased, and the internal corner fixing piece 3 can be more firmly fixed on the wall surface 4.

Preferably, as shown in fig. 3, the end of the fixing base 33 in the extending direction is provided with a second supporting protrusion 35 facing the wall surface 4, and the top end of the second supporting protrusion 35 is flush with the outer bottom wall of the rivet setting groove 331. Thus, on the side facing the wall surface 4, the outer bottom wall of the nail sinking groove 331 is located between the second supporting protrusion 35 and the second supporting protrusion 35, and the outer bottom wall and the second supporting protrusion are abutted against the wall surface 4 together, so that the internal corner fixing piece 3 is abutted against the wall surface 4 more stably.

Further, referring to fig. 3, a nailing line 332 is provided on the bottom wall of the countersunk nail groove 331. When the female angle fixing member 3 is fixed by using the tapping screw, the tip of the tapping screw can be fixed in alignment with the nailing line 332, preventing the nut from protruding out of the fixing base plate 33 due to the warping of the tapping screw during the fixing process.
