Abstract

The utility model relates to a reinforced floor with three lock catches, which comprises high density base materials in the middle and a wearable layer and a waterproof layer on an upper side and a lower side. The reinforced floor with three lock catches is characterized in that two pairs of tongue and groove-rabbet structures which are arranged reversely are arranged on one opposite group of side edges of the floor, wherein the lower part of one edge is provided with the tongue and groove, the concave upper edge of the tongue and groove is shorter, the lower edge is longer, and two concave parts are arranged on the lower edge. The other pair of rabbets is arranged above the tongue and groove, and the rabbets and the tongue and groove share one edge. The lower part is provided with the rabbets, the shapes of which are matched on the other corresponding side edge. The lower part of the other corresponding side edge is provided with rabbets of which the shapes are matched with one another, two opposite bulges are formed on the lower edges of the rabbets, two groups of lock catch structures are formed by the bulges and the concave parts on the tongue and groove, and the other pair of tongue and grooves is arranged above the rabbets. Pressure born by the splicing parts of the reinforced floor is distributed uniformly, and the possibility of damage caused by excessive partial pressure is reduced; at the same time, the generation of high and low differences of the floor is prevented farthest, and the damage of the floor is not easily caused when the high density base materials in the middle are swelled due to water absorption.

Description

Three snap close consolidated floors

Technical field

The utility model relates to a kind of consolidated floor, particularly a kind of consolidated floor that has the multiple fastener structure.

Background technology

The appearance of the consolidated floor of exempting to glue together greatly facilitates the laying of consolidated floor, still, how to keep the smooth of the floor of splicing, and avoids or reduces piece, prolongs the application life on floor, is the problem of a puzzlement industry always.

The applicant discloses a kind of twin-lock button consolidated floor in Chinese patent application 02219971.3, changed the laterally zygomorphic structure of original floor tongue and groove, on a lateral edges on floor, be provided with tenon, relative opposite side edge is provided with tongue and groove, wherein the top of tongue and groove spill is shorter, bottom head, tenon and tongue and groove form fit are provided with two groups of buckle structures in the long bottom of this tongue and groove-tenon combination.This structure makes lays more conveniently, simultaneously, has suppressed the generation and the expansion of piece by the twin-lock buckle structure, has played certain effect.Yet in floor splicing place, it is excessive that local pressure often takes place, and because the one-sided stressed upper and lower displacement friction that causes causes the progressively wearing and tearing of splicing place; On the other hand, the floor is owing to reason such as make moist, be heated can cause expansion, the longitudinal dilatation situation difference on adjacent floor, can cause the difference of height on floor, and the waterproofing course of floor surface and wearing layer are thinner, middle high density base material easily absorbs water and expands, and causes the floor to damage, and this is to have a strong impact on the consolidated floor one of the main reasons in application life.

Summary of the invention

The utility model purpose provides a kind of consolidated floor, both has been convenient to assembly unit, and is not fragile again, prolongs the application life on floor.

For achieving the above object, the technical solution adopted in the utility model is: a kind of three snap close consolidated floors, the high density base material in the middle of comprising and the wearing layer and the waterproofing course of upper and lower surface, on one group of relative side of floor, be provided with two pairs of tongue and groove-tenon structures that oppositely are provided with, wherein Yi Bian bottom is a tongue and groove, the top of tongue and groove spill is shorter, bottom head, in bottom, be provided with two spills, the tongue and groove top is another right tenon, the shared one side of tenon and tongue and groove, on another side of correspondence, the bottom is provided with the tenon of form fit, and the bottom of tenon is provided with two relative projectioies, constitute two groups of buckle structures with the spill on the described tongue and groove, the top of tenon then is provided with another right tongue and groove.

In the technique scheme, the also corresponding tongue and groove-tenon structure that is provided with two pairs of described reverse settings on another opposite side on floor makes the floor extend splicing all around in planar range and lays.

In the technique scheme, described tongue and groove is interior narrow, outer wide configuration, and correspondingly, described tenon is the configuration that head is narrow, root is wide; The length of described tenon slightly is shorter than the degree of depth of tongue and groove, forms the gap when making the floor assembly unit.

In the technique scheme, the last edge lengths of last tenon is less than 2/3 of the length of side on the following tongue and groove, and goes up the top of tenon and horizontal direction angle between 8 °～15 °; This angle is good with 10 °.

Because in following a pair of tongue and groove-tenon structure, the top of tongue and groove is short, the following length of side, when splicing, the floor of tenon one side slightly is inclined upwardly, and the big portion of tenon can be inserted in the tongue and groove, and top edge contacts with the tongue and groove top, the floor is pressed downwards, tenon can slip in the tongue and groove easily, on the other hand, above the length of a pair of tongue and groove-tenon structure less, suitably select the gradient of tenon top earlier, promptly can not influence the splicing on floor.After splicing was finished, because the effect of two buckle structures, adjacent floor was by crosswise fixed, can not throw off, simultaneously, last tongue and groove-tenon group has guaranteed that the floor can not take place to be offset up and down, make after laying the location in flakes, connect closely between the floor, phenomenons such as crack can not take place.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

Because the utility model is short original, down long tongue-and-groove structure above be provided with another to reverse tongue and groove-tenon structure, increased the contact area of floor splicing place, the pressure that is born is more evenly distributed, reduced the possibility that causes damage owing to local pressure is excessive;

2. owing to increased by one group of tongue and groove-tenon structure that oppositely is provided with in addition at former tongue and groove-tenon superstructure, make each side on floor that a tenon and a tongue and groove all be arranged, thereby the mutual restriction power between the floor is strengthened, reduced the floor causes expansion owing to reason such as make moist, be heated possibility, farthest avoided the generation of floor difference of height, thereby the high density base material imbibition in the middle of avoiding causes the damage on floor.
