Description

Anti-pulling seam splicing grounding plate

The technical field is as follows:

the utility model relates to a concatenation floor field specifically is a prevent pulling out seam concatenation board.

Background art:

splice floor wide application fitment trade, install in ground mostly, can make room space grow, present floor all adopts tenon fourth of twelve earthly branches structure to carry out the connection between the floor, but current tenon fourth of twelve earthly branches structure is not suitable for the connection between the floor, produces the joint phenomenon easily in the use, so-called joint pulling is wooden furniture concatenation department splits the seam promptly, has not only reduced the pleasing to the eye degree on floor, influences customer's result of use, makes the unable reutilization in floor moreover.

The utility model has the following contents:

the utility model aims at solving the existing problem, and provide one kind and prevent that the floor from producing the pulling joint phenomenon, the stretching resistance between the reinforcing floor guarantees the pleasing to the eye degree on floor, can also let the floor obtain the pulling joint of preventing of reutilization and piece together the ground board.

The technical solution of the utility model is as follows:

the utility model provides a prevent pulling out seam and piece together ground board, includes a pair of mortise-tenon joint's floor A and floor B at least, floor A one side has the tongue-and-groove, floor B one side have with tongue-and-groove complex tenon, the shaping has multistage upwards sunken ladder groove on the roof of tongue-and-groove, shaping direction inclined plane between the minimum one-step in ladder groove and the tongue-and-groove roof, the top surface shaping of tenon has the ladder lug with ladder groove lock, the shaping of the lower part in tongue-and-groove has spacing lug, the shaping of the lower part of tenon has with spacing lug complex spacing recess, spacing lug has ridge form sand grip to the shaping on the vertical side of spacing lug and spacing recess.

Preferably, the upper and lower edges of the floor boards a and B are chamfered at 45 °.

Preferably, the depth of the stepped groove is gradually deepened upward.

Preferably, the width of the limiting bump is 1/3 of the width of the mortise.

Preferably, the side surfaces of the limiting bump and the limiting groove are in line contact.

Preferably, the upper edge and the lower edge of the mortise and the tenon are in circular arc transition.

Preferably, the stepped groove has at least 3 steps.

Preferably, the step groove and the step convex block are both formed with a retaining slope which is attached to each other.

The beneficial effects of the utility model reside in that: utilize ladder groove and ladder lug cooperation, increase area of contact between the floor, improve the pulling force between the floor, adopt the width to be the cooperation of 1/3's of tongue-and-groove width spacing lug and spacing recess piece, can reach spacing effect, can guarantee the thickness of tenon afterbody again, improve its compressive property, avoid being pressed absolutely, influence the result of use.

Description of the drawings:

FIG. 1 is a schematic cross-sectional view of the floor A and the floor B of the present invention after being spliced;

FIG. 2 is a schematic cross-sectional view of the floor A of the present invention;

fig. 3 is a schematic cross-sectional view of the floor B of the present invention;

in the drawings: 1. a floor A; 2. a floor panel B2; 3. mortises; 4. a tenon; 5. a stepped groove; 6. a stepped projection; 7. a limiting bump; 8. a limiting groove; 9. a convex strip; 10. a backstop slope.

The specific implementation mode is as follows:

as shown in fig. 1-3, the anti-pulling joint splicing board at least comprises a pair of tenon-and-mortise connected floor a1 and floor B2, floor a1 one side has mortise 3, floor B2 one side has tenon 4 matched with mortise 3, the top wall of mortise 3 is formed with multi-step upwards-recessed step groove 5, the top surface of tenon 4 is formed with step convex block 6 buckled with step groove 5, the lower part of mortise 3 is formed with limit convex block 7, the lower part of tenon 4 is formed with limit concave groove 8 matched with limit convex block 7, the vertical side surfaces of limit convex block 7 and limit concave groove 8 are relatively formed with ridge convex strip 9, after the floor is buckled, the highest position of convex strip 9 forms line contact, this structure ensures that the lower parts of two floors are mutually matched, so that the whole tenon-and mortise structure is stressed more uniformly and stably, if a surface contact structure is adopted, the two side faces are not jointed due to the influence of the ground levelness or the floor side face verticality, so that the spliced floor tenon-and-mortise structure is unstable in stress, slips and separates, and even the tenon 4 is broken.

Specifically, the upper and lower edges of the floor panel a1 and the floor panel B2 are chamfered at 45 °.

Specifically, the depth of the stepped groove 5 is gradually deepened upward.

Specifically, the width of spacing lug 7 is 1/3 of tongue-and-groove 3 width, and the spacing lug 7 and the spacing recess 8 that adopt the 1/3 of width for the tongue-and-groove 3 width cooperate, can reach spacing effect, can guarantee the thickness of tenon 4 afterbody again, improve its compressive property, avoid being broken by the pressure, influence result of use.

Specifically, the side surfaces of the limiting bump 7 and the limiting groove 8 are in a line contact type.

Specifically, the upper edge and the lower edge of the mortise 3 and the tenon 4 are in arc transition.

Specifically, the stepped groove 5 has at least 3 steps.

Specifically, the stopping slope 10 that the looks laminating all is formed on ladder groove 5 and the ladder lug 6, prevents to loosen and takes off the separation between the floor.

During splicing and installation, the floor B2 is horizontally placed on the ground, the stepped convex block 6 faces upwards, the mortise 3 on one side of the floor A1 is buckled with the tenon 4 of the floor B2, and the floor A1 is flattened until the side faces of the limiting convex block 7 and the limiting groove 8 form line contact.

The above description is only a preferred embodiment of the present invention, and all other embodiments obtained by those skilled in the art without any creative effort shall fall within the protection scope of the present invention.
