[0024] A highly stable ALC board splicing structure comprises an ALC board body 1, the cross section of the ALC board body 1 is an isosceles trapezoid as a whole, the inclined surfaces on the left and right sides of the ALC board body 1 are fitting parts 2, the fitting parts 2 are inclined at an angle of 45° to the outer facade of the ALC board body 1, and the fitting parts 2 are inclined as a whole, which can effectively increase the contact area between the ALC board bodies 1, increase the friction between the ALC board bodies 1, and increase the stability of the connection.

[0025] The two fitting parts 2 are respectively provided with a tenon 3 and a tenon groove 4, both of which are stepped, and the cross section of the tenon 3 is an equilateral right triangle. The tenon groove 4 cooperates with the tenon 3 on the adjacent ALC board body 1, and the tenons 3 on both sides of the fastening pin 5 are symmetrical. Through the cooperation of the tenon 3 and the tenon groove 4, the ALC board bodies 1 can be arranged and combined in a straight line or at a right angle, which is suitable for the installation of corners between walls in building structures.

[0026] A fastening pin 5 is embedded in the middle position of the fitting part 2 with the tenon 3, and a pin hole 6 matching the fastening pin 5 is provided in the middle position of the fitting part 2 with the tenon groove 4. The fastening pins 5 are distributed equidistantly in the longitudinal direction on the fitting part 2, and there are no less than three fastening pins 5 arranged on each fitting part 2. The fastening pins 5 can be made of high-strength steel bars to prevent them from breaking easily; the outer end surface of the fastening pin 5 and the inner end surface of the pin hole 6 are both hemispherical structures, which are convenient for reducing the resistance of the fastening pin 5 passing through the pin hole 6; the axis of the fastening pin 5 is perpendicular to the plane where the fitting part 2 is located, and the two fitting parts 2 to be spliced ​​are always kept in a parallel state during installation, so that the fastening pin 5 can be inserted into the pin hole 6 while the tenon 3 and the tenon groove 4 are also fitted, and the tenon 3 and the tenon groove 4 can further increase the contact area between the fitting parts 2, and at the same time resist the lateral shear force generated by the external force, and cooperate with the fastening pins 5 to make the adjacent ALC board bodies 1 difficult to separate, effectively improving the stability of the splicing.

[0027] A sealant layer 8 is provided on the surface of the tenon 3 and the tenon groove 4. The sealant layer 8 has a certain elasticity and flexibility. When spliced, the sealant layers 8 are squeezed against each other by pressure to produce deformation and fit closely, fully filling the gap between the ALC board bodies 1, effectively blocking moisture penetration and air circulation, and improving the waterproofness and sound insulation of the structure.

[0028] A guide groove 7 is provided on the top and bottom surfaces of the ALC board body 1. The guide groove 7 is located in the middle of the top and bottom surfaces of the ALC board body 1. The guide grooves 7 between two adjacent ALC board bodies 1 are connected. Glue injection holes 9 are provided on both sides of the guide groove 7. The two glue injection holes 9 are staggered.

After filling, excess material flows out through the glue injection holes 9 on the other side, and then the ALC board body 1 and the floor slab are reinforced again through a series of fasteners to ensure a stable connection of the ALC board body 1.

[0029] Working principle: When splicing, stand up the ALC board body 1 along the installation line defined by the upper and lower floor slabs, align the tenon 3 and the fastening pin 5 on the next ALC board body 1 to be installed with the tenon groove 4 and the pin hole 6 on the installed ALC board body 1, insert the fastening pin 5 into the pin hole 6, and make the tenon 3 and the tenon groove 4 fit together; after the installation is completed, inject foam glue and other materials into the guide groove 7 through the glue injection hole 9 to make the top and bottom surfaces of the ALC board body 1 fit with the upper and lower floor slabs respectively.
