example 1
As shown in fig. 1 and 2, an OSB composite core board comprises a core board body 1, wherein the core board body 1 is formed by stacking a fiber mesh fabric 11, an OSB board 12, a splicing board 13 and an OSB board 12 which are sequentially arranged from top to bottom, wherein the splicing board 13 comprises a surrounding frame on the periphery, and an OSB board strip 130 and a heat insulation board strip 131 which are obliquely and sequentially arranged in the surrounding frame at intervals. It should be noted that the dimensions of the enclosure frame are consistent with the dimensions of the OSB panel, so that the sides remain flat after compounding. The fiber mesh cloth 11 is provided with at least one layer so as to be matched with other building materials for use. The OSB board laths 130 and the heat-insulation board laths 131 which are obliquely arranged are sequentially obliquely arranged at intervals, so that better vertical and lateral mechanical resistance can be ensured, and the heat-insulation board laths 131 filled in the middle of the OSB board laths 130 are increased in heat insulation and sound insulation performance.
Specifically, in this embodiment, the OSB board slats 130 and the heat insulation board slats 131 are both obliquely arranged in the enclosure frame at an angle of 45 °, and the enclosure frame is sequentially spliced by four splicing slats 132 to form a square frame. The insulation panel strips 130 may be cut from a glass insulation cotton board. For firm fitting, the OSB composite core panel may be compounded by gluing or adhesively bonding fasteners such as gun nails, screws, and the like. The OSB panel strips are strips 100mm wide and 18mm thick. The thickness of the OSB board 12 is also 18 mm.
The OSB composite core board can be used for manufacturing an assembled composite heat-insulation wallboard. The wall board comprehensively considers the structural bearing performance, the heat preservation and sound insulation performance and the assembling performance of the wall body.

The technical effect of heat preservation and sound insulation is enhanced by asymmetric reverse 45 degrees. Specifically, the center distance between two adjacent OSB battens 130 of the splice plate 12 is 400mm, and the heat-insulating cotton board battens 131 are filled between the OSB battens to form two +/-45-degree enhanced function plates. The two functional boards are respectively placed on two sides of the heat preservation layer, so that the vertical load of the wallboard is born by the 18mm OSB boards on the two sides, and the horizontal loads in two directions are born by the splicing plates of the +/-45-degree battens, so that the wallboard has good vertical and lateral mechanical resistance. Meanwhile, the heat insulation cotton filled in the middle of the splice plates increases the heat insulation and sound insulation performance of the wallboard.
