Preferably, the two daughter board connections are bonded by an adhesive layer.
Preferably, the length and width of the second rectangular groove are half of the length and width of the first rectangular groove, respectively.
Preferably, each corner of the second rectangular groove is provided with a through hole.
As a further preference, the through hole is a circular hole.
Preferably, the center of the through hole is located at a corner of the second rectangular groove, and the second rectangular groove with the circular through hole at four corners is bone-shaped.
Preferably, the finger-joint structures are communicated through straight grooves, the straight grooves are perpendicular to the first rectangular grooves and the second rectangular grooves, and the heights of the straight grooves are consistent with those of the first rectangular grooves.
Preferably, the width of the straight groove is smaller than the length of the second rectangular groove.
Preferably, the plurality of finger structures are evenly distributed between the two sub-boards.
Compared with the prior art, the utility model has the advantages of convenient processing, single-side cutting, one-step in-place and seamless butt joint of the front side and the back side; the finger joint contact area is large, the bonding fastness is good, and the bending strength is high; the method provides a new solution for the long strip-shaped plate for the suspended ceiling, and saves the die opening cost.

Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art based on these embodiments are all included in the scope of the present invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
As shown in figures 1 and 2, the finger joint board for the suspended ceiling comprises two symmetrically arranged sub-boards 1, wherein the sub-boards 1 are connected through a plurality of finger joint structures 2, and the joints of the two sub-boards 1 are adhered through adhesive layers. A plurality of finger joint structures 2 are evenly distributed between the two daughter boards, and the number of the finger joint structures 2 can be set according to the requirement.
As shown in fig. 3, the finger-joint structure 2 is a stepped groove formed by overlapping a first rectangular groove 21 and a second rectangular groove 22, wherein the length and the width of the second rectangular groove 22 are both smaller than those of the first rectangular groove 21, and the sum of the heights of the first rectangular groove 21 and the second rectangular groove 22 is equal to the thickness of the daughter board 1.
