[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0021] Please refer to Figures 1 to 5 The graphite extruded board for building energy-saving insulation can include a board body 10, a grid layer 20, an I-shaped filling strip 30 and a U-shaped filling strip 40. The board body 10 is formed with a plurality of arrayed conical protrusions 12 on one side, and the graphite extruded board is formed with the side of the board body 10 on which the conical protrusions 12 are formed facing the building wall when the graphite extruded board is bonded to the building wall. The grid layer 20 is fixed on the side of the board body 10 on which the conical protrusions 12 are formed by hot pressing, so that the grid layer 20 and the board body 10 form a composite structure. The opposite sides of the board body 10 are both formed with U-shaped grooves 11. When the graphite extruded boards in the same row are installed on the building wall, one of the graphite extruded boards can be first bonded and fixed to the building wall, then the I-shaped filling strip 30 is inserted into the U-shaped groove 11 of the board body 10 of the graphite extruded board, and then the board body 10 of the other graphite extruded board is inserted into the I-shaped filling strip 30 by means of the U-shaped groove 11, so that the two graphite extruded boards are aligned. Thus, the I-shaped filling strip 30 can be used to fill the U-shaped grooves 11 on the facing sides of the adjacent two board bodies 10, and the I-shaped filling strip 30 is clamped and connected between the adjacent two board bodies 10, so that the graphite extruded boards can be positioned and assembled when combined and spliced. In the plurality of graphite extruded boards in the same row, the board bodies 10 of the graphite extruded boards at both ends are not adjacent to the U-shaped grooves 11 on the sides of the other board bodies 10, and the U-shaped filling strip 40 can be used to fill the U-shaped grooves 11. The joint between the U-shaped groove 11 and the I-shaped filling strip 30 or the U-shaped filling strip 40 can also be coated with adhesive.

[0022] In the embodiment, the grid layer 20 includes a plurality of transverse fibers 21 and a plurality of longitudinal fibers 22, and the transverse fibers 21 and the longitudinal fibers 22 can both be glass fibers. The plurality of transverse fibers 21 and the plurality of longitudinal fibers 22 are cross-connected to form a grid structure having a plurality of mesh holes 23 on the surface, and the plurality of mesh holes 23 on the grid layer 20 are respectively sleeved outside the plurality of conical protrusions 12 on the board body 10. The length and width of the conical protrusion 12 are both smaller than the length and width of the mesh hole 23, and the protrusion height of the conical protrusion 12 is smaller than the thickness of the grid layer 20. When the graphite extruded board is connected and fixed to the building wall by means of the adhesive, the grid layer 20 can be used to improve the pullout resistance of the anchorage point, and in addition, the conical protrusions 12 formed on the surface of the board body 10 can increase the mechanical engagement area, thereby improving the bonding strength in cooperation with the adhesive.
