Abstract

The utility model discloses a lock buckle type tenon groove floor. A triangle locking type structure with a tenon head and an elbow concave tenon groove is used by the lock buckle type tenon groove floor. An appropriate gap is left in a junction surface of the tenon head and the tenon groove. When assembled, an inclined surface of the triangle clock buckle is in favor of the tenon groove being easily led in by the tenon head. When a slitting tendency appears, the slotting extension can be effectively restrained by the binding force of the inclined surface of the triangle clock buckle and the elbow. When floors which are made by using the utility model are used, the laying close joint character can be improved, and not only are assembly and many times of disassembly easy, but also the requirement of mechanical strength of base materials is reduced simultaneously. When an alpha angle of the triangle lock buckle is 30-65 DEG and a beta angle is 20-35 DEG, the effect is better.

Description

Bayonet type tongue-and-groove floor

The utility model relates to a kind of tongue-and-groove floor, particularly relates to a kind of bayonet type tongue-and-groove floor.

Plug in construction is generally adopted on existing tongue-and-groove floor.During laying construction, tend to influence the close joint on floor, produce and lay piece because the constructor lays factor such as technical ability, laying experience.And because structural defective, As time goes on, piece can increase to tens, and even 1～2 millimeter.In addition, the floor just is difficult to carry out again dismounting in case laying finishes.ZL98223590.9 has disclosed a kind of hook-type tongue-and-groove floor, although it can improve laying efficient, improve the close joint of laying, because it emphasizes that too tenon combines the adhesion on inclined-plane with the tongue-and-groove hook-type, therefore to the having relatively high expectations of floor base material mechanical strength, cost rises.And it adopts no gap to cooperate, and damages structure again during dismounting easily on the floor.

The purpose of this utility model is: provide a kind of the improvement to lay close joint, not only be easy to assembly unit but also the suitable repeatedly bayonet type tongue-and-groove floor of dismounting.

Task of the present utility model is achieved in that a kind of bayonet type tongue-and-groove floor of being made up of panel layer and assembly unit layer, and the assembly unit layer adopts the bayonet type insert structure that has tenon and elbow spill tongue-and-groove.Adopt the chain of triangulation buckle structure that is epirelief with the tenon at tongue-and-groove bonding surface place, spill tongue-and-groove corresponding with it then is recessed triangular shape, leaves suitable gap between the bonding surface of tenon and tongue-and-groove.When assembly unit or dismounting, the inclined-plane of triangle snap close helps tenon and successfully imports tongue-and-groove, and when occurring cracking trend, and the adhesion on triangle snap close inclined-plane and elbow can suppress the expansion of cracking again effectively.When the α angle of chain of triangulation buckle structure is 30～65 °, when the β angle was 20～35 °, effect was better.

The utility model had both guaranteed suitable adhesion owing to adopted the chain of triangulation buckle structure, improved the close joint on floor, had reduced the requirement to the base material mechanical strength simultaneously again;

Leave suitable gap between the triangle snap close of tenon and the bonding surface of spill tongue-and-groove, not only be easy to assembly unit but also suitable repeatedly dismounting;

The chain of triangulation buckle structure adopts 30～85 ° α angle and 20～42 ° β angle, has better assembly, dismounting effect;

Adopt suitable chamfer length, both be convenient to install, have suitable resistance again, restricted the generation or the expansion of piece.

Below, in conjunction with the accompanying drawings, introduce the utility model in detail.

Accompanying drawing is a structural representation of the present utility model.

Embodiment one

The bayonet type tongue-and-groove floor of adopting composite material to make is made up of panel layer 5 and assembly unit layer.One side of assembly unit layer has tenon 4, adopts the chain of triangulation buckle structure that is epirelief with spill tongue-and-groove 7 bonding surface places on the tenon 4.The opposite side on bayonet type tongue-and-groove floor is a spill tongue-and-groove 7, is corresponding recessed triangular shape.During laying, apply glue respectively in tenon 4 and spill tongue-and-groove 7 and carry out assembly unit, the inclined-plane of triangle snap close helps tenon 4 and successfully imports spill tongue-and-groove 7, until panel layer 5 tight close joints.At this moment, leave suitable gap between the bonding surface 6 and 2 of tenon 4 and spill tongue-and-groove 7.And when occurring cracking trend, the elbow 3 at spill tongue-and-groove 7 recessed triangle places can suppress the expansion of cracking again effectively.If the floor needs dismounting at short notice, can directly carry out assembly unit, needn't be in tenon 4 and spill tongue-and-groove 7 spreading glue.

Embodiment two

The bayonet type tongue-and-groove floor of adopting various timber directly to make is made up of panel layer 5 and assembly unit layer.One side of assembly unit layer has tenon 4, adopts the chain of triangulation buckle structure that is epirelief with spill tongue-and-groove 7 bonding surface places on the tenon 4.The α angle of chain of triangulation buckle structure is 30～85 °, and the β angle is 20～42 °, and the angle of tenon end 8 and panel layer 5 is greater than 65 °.The opposite side on bayonet type tongue-and-groove floor is a spill tongue-and-groove 7, is corresponding recessed triangular shape.During laying, will carry out assembly unit in the tenon 4 embedding spill tongue-and-grooves 7.It had both helped tenon 4 and had successfully imported spill tongue-and-groove 7 triangle snap close suitable length in conjunction with the inclined-plane, made tenon 4 have suitable adhesion with the inclined-plane 6 and 2 that combines of spill tongue-and-groove 7 again.When panel layer 5 close proximity, leave suitable gap between the bonding surface of tenon 4 and spill tongue-and-groove 7.

Claims

1. bayonet type tongue-and-groove floor of forming by panel layer (5) and assembly unit layer, the assembly unit layer adopts insert structure, one side on floor is tenon (4), relative opposite side is for having the spill tongue-and-groove (7) of elbow (3), inclined-plane (2) on the inclined-plane (6) of tenon (4) and the spill tongue-and-groove (7) is complementary, it is characterized in that adopting the chain of triangulation buckle structure that is epirelief with the tenon (4) at tongue-and-groove bonding surface place, spill tongue-and-groove corresponding with it (7) then is recessed triangular shape, leaves suitable gap between the bonding surface (6) of tenon (4) and spill tongue-and-groove (7) and (2).

2. bayonet type tongue-and-groove according to claim 1 floor, the α angle that it is characterized in that described chain of triangulation buckle structure is 30～85 °, the β angle is 20～42 °.
