Description
Technical field
The utility model relates to a kind of floor assembly unit auxiliary connection, belongs to decorative material technology.
Background technology
Strip composite floor board and wooden floor splice the position mutually at it, all are provided with interface pair, following interface pair and assembly unit auxiliary connection, and the assembly unit auxiliary connection is in both centres of the secondary and following interface pair of interface.The utility model is related is provided in a side of the assembly unit auxiliary connection that the position is spliced on the floor mutually.
The form of structure of existing floor auxiliary connection is numerous, but it is firm all must to satisfy snapping, the flexible distortion that can not warp in floor, and splicing is convenient, and joint gap will wait technical requirements as far as possible for a short time.In recent years, accidental circular arc tenon tongue-and-groove snapping pair, because characteristics such as snapping intensity that it had is big, and good by floor research staff and customer.But, this circular arc tenon tongue-and-groove snapping pair, because its tenon and tongue-and-groove all are single arc surface structure, under its splicing state, whole tenon and tongue-and-groove arc surface cooperate and connect airtight, thereby on the floor when flexible, distortion extremely easily warps; And because it connects airtight the very little or not applying glue of position resin added, thus not firm after the splicing of floor, extremely be easy to generate loosening; And assembly unit is also very inconvenient.This is said existing circular arc tenon tongue-and-groove snapping pair, the deficiency that is come out in actual use.
Summary of the invention
The purpose of this utility model is to make improvements at the deficiency of existing circular arc tenon tongue-and-groove snapping pair, provide the distortion that is difficult for warping after a kind of splicing, splicing to stablize firm and assembly unit floor assembly unit easily auxiliary connection, to solve the secondary existing problem of existing circular arc tenon tongue-and-groove snapping.
The utility model realizes that the technical scheme of its purpose is, a kind of floor assembly unit auxiliary connection comprises tongue-and-groove that is the indent convex structure that is located on the Mosaic face of left floor and the tenon that is the evagination convex structure that is located on the Mosaic face of right floor; Interior concaved circular cambered surface and outer convex arc surface are closed mutually; Its improvement is: the outer convex arc surface of said tenon is the two arc surface structures that are connected by interior concaved circular cambered surface transition by little arc surface of evagination and outer convex arc surface; Between the interior concaved circular cambered surface of the little arc surface of evagination of tenon and interior concaved circular cambered surface and tongue-and-groove, be provided with the gap.
Can understand by above given technical scheme, because the outer convex arc surface of tenon of the present utility model is two arc surfaces, and between the little arc surface of tenon evagination and interior concaved circular cambered surface and tongue-and-groove arc surface, has the gap, both expanded and left extending space to the floor, the capacity of applying glue and the reasonability of applying glue have been improved again, and to attractive in appearance modification of tongue and groove part, thereby the distortion that is difficult for warping after the splicing, assembly unit is also very convenient; Simultaneously again owing between the great circle cambered surface and tongue-and-groove arc surface of tenon, bigger connection bonding surface is arranged, thus snapping stablize firm, thereby realized the purpose of this utility model.
The further improvement of the utility model point is:
The central angle of the interior concaved circular cambered surface of tongue-and-groove is 120 °～140 °; The central angle sum of little arc surface of the evagination of tenon and interior concaved circular cambered surface is 50 °～65 °.
Tongue-and-groove and tenon are in the middle part of left floor and right floor gross thickness respectively, and its upper edge hole leaves the distance of left floor and right floor upper surface, equal 1/4 of left floor and right floor gross thickness respectively.
More than two given further improvements, be further qualification to the utility model part important technology parameter, also be further qualification to its geometry.This is preferred through institute after the repetition test.It both can be fit to strengthening composite floor, also can be fit to wooden floor.Connecting fastness and the distortion and further facilitate technique effect such as assembly unit of being difficult for warping for the assembly unit that improves the floor, all is best.
Be provided with at the front end of tenon and be used for making things convenient for the floor to clap the inclined-plane that is merged dress.Because the existence on inclined-plane when adjacent two floors splice, can the bat of implementation level be closed connection.This just is more convenient for the assembly unit on floor.
After technique scheme was implemented, floor assembly unit that the utility model had connects stablized firmly, and the assembled floor characteristics such as distortion and assembly unit make things convenient for that are difficult for warping are conspicuous.
