the opposite surfaces of the middle wood-accumulating plate 1 and the side wood-accumulating plates 2 form the finger-joint surfaces 3, so that the middle wood-accumulating plate 1 and the side wood-accumulating plates 2 positioned at two sides of the middle wood-accumulating plate 1 are fixed in a finger-joint matching mode, and the middle wood-accumulating plate 1 and the side wood-accumulating plates 2 with shorter lengths can jointly form a long plate with longer lengths in a finger-joint mode, so that the surplus materials of other wooden toys can be selected as the original plates 5 of the middle wood-accumulating plate 1 and the side wood-accumulating plates 2;

wherein, the finger joint surface 3 is a coating surface at the same time, the finger joint surface 3 is coated with a colloid (not shown in the drawing), in this embodiment, the colloid can be selected from epoxy resin glue and other strong glue, compared with the colloid coated on a flat surface, more colloid can be attached, thereby increasing the gluing area between the middle wood board 1 and the side wood boards 2 at both sides, further enhancing the stability of the whole structure, meanwhile, when the arch bridge component 8 formed by the above structure falls from a high position and collides with the ground, or collides with foreign objects due to other reasons, the surfaces of the middle wood board 1 and the side wood boards 2 can be subjected to larger external acting force, so that the stress in the middle wood board 1 and the side wood boards 2 is increased, at this time, the colloid at the finger joint position with a large area can disperse the stress in the middle wood board 1 and the side wood boards 2, therefore, stress concentration is prevented, excessive deformation of the middle wood-laying plate 1 and the side wood-laying plate 2 is avoided, and cracking along wood grains is avoided, compared with the prior art, the arch bridge assembly 8 of the rainbow arch bridge building block has higher strength, and can resist severe collision through the requirement of a 12M + toy drop test, so that the possibility of cracking under severe collision is greatly reduced, and the rainbow arch bridge building block is more suitable for being played and used by children with good naturalness in the 0-3 year old;

constitute the contained angle between the wood grain on the long-pending plank of middle part 1 and the wood grain on the long-pending plank 2 of lateral part, view the wood grain on long-pending plank 1 of middle part and the long-pending plank 2 of lateral part on the whole and be not perpendicular to arched bridge subassembly 8's surface, but relative arched bridge subassembly 8 surface is the tilt state, so when arched bridge subassembly 8 collides with the foreign object, can avoid the direct transmission along the wood grain direction of external force footpath, make the long-pending plank 1 of middle part and the long-pending plank 2 of lateral part be located near the wood grain part and can bear bigger stress simultaneously, thereby can further improve arched bridge subassembly 8's structural strength, avoid taking place the fracture with the wood grain department, also can reduce simultaneously original panel 5 and wet the inflation and air-dry the possibility of taking place the fracture along the wood grain direction when contracting.

As shown in fig. 2 to 5 and 7 to 9, further, the middle wood stacking board 1 and the side wood stacking boards 2 are isosceles trapezoids, when manufacturing, the middle wood stacking board 1 is inverted, so that the middle wood stacking board 1 can be clamped by the waist portions of the two side wood stacking boards 2, and when the middle wood stacking board 1 and the side wood stacking boards 2 are in a certain height, the area of the contact surface between the middle wood stacking board 1 and the side wood stacking boards 2 can be maximized by connecting the waist portions, and in this embodiment, to enable seamless connection between the middle wood stacking board 1 and the side wood stacking boards 2, the included angle formed by the two waist portions of the middle wood stacking board 1 and the upper bottom and the lower bottom thereof is configured to be consistent with the included angle formed by the two waist portions of the side wood stacking boards 2 and the two waist portions of the middle wood stacking board 1 can be seamlessly connected with the waist portions of the side wood stacking boards 2, meanwhile, the middle wood-stacking boards 1 and the side wood-stacking boards 2 are connected in a finger joint mode through the finger joint faces 3 on the waist, so that the side wood-stacking boards 2 are inclined relative to the middle wood-stacking boards 1 in the placing positions, and an included angle can be directly formed between wood grains on the middle wood-stacking boards 1 and wood grains on the side wood-stacking boards 2.

As shown in fig. 2 to 3, further, the finger joint surface 3 is formed on the waist portion of the middle wood board 1 and the side wood board 2, and by the above arrangement, the middle wood board 1 and the side wood board 2 can have a larger area of the finger joint surface 3, thereby ensuring the stability in direct connection.

As shown in fig. 6, further, the finger joint surface 3 includes a plurality of finger grooves 301 arranged at intervals, and finger protrusions 302 are correspondingly formed between two adjacent finger grooves 301, in this embodiment, the distance, the width, the depth, and the shape between each finger groove 301 are all the same, and the distance, the width, the length, and the shape between each finger protrusion 302 are respectively the same as the shape and the depth of the finger groove 301, so as to ensure that each finger protrusion 302 on the finger joint surface 3 of the middle wood board 1 can be completely inserted into the finger groove 301 on the finger joint surface 3 of the side wood board 2, and also ensure that the finger protrusions 302 on the side wood board 2 can be completely inserted into each finger groove 301 on the finger joint surface 3 of the middle wood board 1, and can eliminate the height difference of the outer edge of the finger joint, and ensure the flatness of the finger joint.

As shown in fig. 6, further, the finger-joint surfaces 3 are formed by milling, and during manufacturing, the finger-joint surfaces 3 of the middle wood-laminated board 1 and the side wood-laminated boards 2 are kept opposite to the cutting edge of the milling cutter 6, and the milling cutter 6 is moved to machine the finger grooves 301 and the finger protrusions 302.

As shown in fig. 6, further, two side walls of the free end 302a of the finger protrusion 302 incline towards each other to form a wedge shape, and the inner wall of the corresponding finger groove 301 close to the bottom side of the groove inclines towards each other to form a wedge shape matching with the free end 302a of the finger protrusion 302, so that the contact surface between the finger groove 301 and the finger protrusion 302 is increased, and the connection between the middle wood stacking board 1 and the side wood stacking board 2 is more stable.

Further, the colloid coats on the surface that indicates groove 301 and indicate protruding 302, based on indicate protruding 302 and indicate the wedge structure of groove 301 for the area of the attachment surface of colloid obtains increasing, and then makes the connection position of middle part long-pending plank 1 and the long-pending plank 2 of lateral part can obtain higher intensity, guarantees further to reduce the possibility that middle part long-pending plank 1 and lateral part long-pending plank 2 ftractures when taking place comparatively violent collision.

As shown in fig. 9, further, the outer walls of the middle wood floor 1 and the side wood floor 2 are provided with a plurality of groups of cutting lines 4 in a scribing manner, and each group of cutting lines 4 is spaced from each other, it should be mentioned that the cutting lines 4 of each layer on the middle wood floor 1 are consistent with the cutting lines 4 of the same layer on the side wood floor 2, and based on the above arrangement, the number of subsequent sawing times can be reduced, so that the middle wood floor 1 and the side wood floor 2 can be rapidly sawn into a plurality of arch bridge assemblies 8 at the same time.
