Technical Field

The invention relates to the technical field of plate splicing, in particular to a splicing piece.

Background

In the prior art, in order to manufacture splicing pieces of pure solid wood structures such as solid wood platens, solid wood doors and the like with large areas, a plurality of solid wood plates are usually bonded by strong glue, and then veneers are paved, or the solid wood plates are connected by a tenon-and-mortise structure and reinforced by strong glue. That is, the solid wood splice in the prior art inevitably uses industrial glue, which is obviously not environment-friendly enough.

Disclosure of Invention

The invention aims to solve the technical problem of providing a seamless splicing piece which is spliced only by using a mortise and tenon structure and does not need to be reinforced by adopting industrial viscose glue.

In order to solve the technical problems, the technical scheme of the invention is as follows: a seamless splicing piece comprises a first component and a second component which are spliced with each other, wherein a first tenon and a first mortise which are as long as the end surfaces are arranged at one end of the first component, which is used for connecting the second component, and a second tenon and a second mortise which are as long as the end surfaces are arranged at one end of the second component, which is used for connecting the first component; the shape structures of the first tenon and the second tenon are completely the same, and the shape structures of the first mortise slot and the second mortise slot are completely the same; the first mortise slot and the second mortise slot are both obliquely arranged U-shaped slots and comprise slot bottoms and two face slot walls, wherein one face is a flat slot wall, the other face slot wall is provided with a convex part, so that the whole U-shaped slot is of a structure with a wide inner part and a wide outer part and a narrow middle part, the tenon structures of the first tenon and the second tenon correspond to the structure of the U-shaped slot and comprise a top part and two outer walls, one of the outer walls is a flat outer wall, and the other outer wall is provided with an inner concave part; the first component and the second component are pressed and spliced in a positive and negative symmetrical mode, the first tenon is completely embedded into the second mortise, and the second tenon is completely embedded into the first mortise.

Among the above-mentioned technical scheme, because the mortise slot structure in first mortise slot and second mortise slot has the interior narrow characteristics in the middle of the outer width, the tenon structure of first tenon and second tenon is corresponding with the structure in U-shaped groove, and the solid has certain elastic deformation usually, just so can press the concatenation with first component and second component according to positive and negative symmetry's mode, make first tenon imbed the second mortise slot completely, the second tenon imbeds first mortise slot completely, two components will be very firm after the concatenation through two mortise structures, need not to adopt the industry viscose to consolidate. Moreover, as the shape structures of the first tenon and the second tenon are completely the same, and the shape structures of the first mortise slot and the second mortise slot are completely the same, the processing of the first component and the second component is very simple, the precision of the mortise structures on the two components can be ensured, and the seamless splicing is facilitated; moreover, the tenon and the mortise can be machined on a long strip-shaped plate, and then the first member and the second member, or even more members, can be obtained by cutting according to the size.

As an optimized technical scheme, the bottoms of the first mortise slot and the second mortise slot are arc bottoms, and the tops of the first tenon and the second tenon are arc tops.

According to the preferable technical scheme, the first tenon and the first mortise slot are positioned in the middle of the end face of the first component, and the flat slot wall of the first mortise slot is also the flat outer wall of the first tenon; the second tenon and the second mortise are positioned in the middle of the end face of the second component, and the leveling groove wall of the second mortise is also the leveling outer wall of the second tenon. The design ensures that the tenon and the mortise are interdependent in structure, and the structure is very ingenious and compact.

As an optimized technical scheme, the arc bottom of the first mortise slot and the arc top of the first tenon are connected through the flat slot wall/the flat outer wall to form an S shape, and the arc bottom of the second mortise slot and the arc top of the second tenon are connected through the flat slot wall/the flat outer wall to form an S shape.

Preferably, the first mortise slot and the second mortise slot are provided with a plurality of convex parts, and the cross-section lines of one slot wall are wavy lines; the cross-section lines that first tenon and second tenon all have a lateral wall are the wavy line, have a plurality of interior recesses. This structure can further enhance the fastening of the two members after splicing.

Preferably, the depth of the first mortise slot and the second mortise slot is slightly larger than the length of the first tenon and the length of the second tenon. Just so can guarantee that the tenon inserts completely to fourth of twelve earthly branches inslot, avoid influencing the inseparable laminating of first component and second component terminal surface because there is burr or piece in the groove of fourth of twelve earthly branches.

Preferably, the opening of the U-shaped groove is in interference fit with the root of the tenon structure. Therefore, the obvious gap can not be seen at the joint of the surfaces of the two spliced components.

In one embodiment, the first member and the second member are both solid wood plates.

In one embodiment, the first member and the second member are both plastic plates.
