Abstract

The utility model relates to a clamping type keel for solid wood floors, which comprises the keel (1) and a group of spring fasteners (2) which are provided with upper and lower clamping boards (2-1, 2-2), wherein, the upper part of the keel (1) is provided with a T-shaped sliding slot (8) along an axial cord direction; the lower clamping boards (2-2) of the spring fastener (2) are arranged inside the sliding slot (8) in the method of movable fit. The clamping type keel for solid wood floors also comprises a group of pressing boards (6) which are provided with installing holes (5). The lower parts of both sides of the keel (2) are provided with clamping slots (3) for connecting the pressing boards (6). One end of each pressing board (6) is provided with a flanging (6-1) corresponding to the clamping slots (3). In addition, the flanging (6-1) of each pressing board (6) is clamped into the clamping slots (3). Tongue-and-groove floors of the solid wood, which are arranged by using the clamping type keel for solid wood floors are unable to generate up and down movements, are free from noise, and pavement quality is good. Iron nails are replaced by clamping type connection by the clamping type keel for solid wood floors. The floors can be expanded freely without deformation or warpage, and are also convenient for installation, disassembly, and renewing for permanent use.

Description

Wooden floor cassette keel

Technical field

The utility model relates to the keel that a kind of wood floors assembly unit is used, and particularly a kind of can grooved and tongued floor can being connected to each other through it cooperates all-in-one-piece wooden floor cassette keel.

Background technology

The installation of existing wooden tongue-and-groove joint floor all needs perforating on the ground earlier, and fixing rough ground is spread wooden tongue-and-groove joint floor after levelling then, and its shortcoming is: the construction technology complexity, and the dismounting difficulty, efficiency of construction is lower.Chinese patent CN2379544Y discloses a kind of wooden floor cassette keel, form by keel and elastic card, though overcome above-mentioned shortcoming, but still there is following defective, because the planeness of the original ground before the construction and the construction requirement that levelness does not reach the wooden tongue-and-groove joint floor piece, cause wooden tongue-and-groove joint floor flawless, when floor surface bears pressure, make wooden tongue-and-groove joint floor on original ground, produce upper and lower motion easily, thereby the generation sound badly influences the mat formation effect and the quality of mating formation of wooden tongue-and-groove joint floor.

Summary of the invention

The purpose of this utility model provides a kind of wooden floor cassette keel, and the wooden floor that uses it to install can not produce upper and lower motion, noiselessness, and the quality of mating formation is good.

The technical scheme that realizes above-mentioned purpose is: a kind of wooden floor cassette keel, comprise keel and one group of snak link with upper and lower clamp, keel top is provided with "T"-shaped chute along axis direction, the following clamp of snak link is arranged in the chute movingly, also comprise one group of pressing plate with installing hole, two side lower parts of keel have the draw-in groove that connects pressing plate, and an end of pressing plate has the flanging corresponding with draw-in groove, and the flanging of pressing plate is stuck in the draw-in groove.

After adopting technique scheme, increased by one group of pressing plate, and have the draw-in groove that connects pressing plate at keel two side bottoms, and the flanging of pressing plate is stuck in the draw-in groove, has installing hole on the pressing plate, pressing plate can be fixed on the ground by screw, and by pressing plate keel are fixed on the ground, can prevent effectively that wooden tongue-and-groove joint floor from installing the back because the caused keel of pressure-bearing move up and down, eliminated noise, even the ground out-of-flatness fixingly after levelling also can reach the good effect of mating formation.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～5, a kind of wooden floor cassette keel, comprise keel 1 and one group of snak link 2 with upper and lower clamp 2-1,2-2, keel 1 top is provided with "T"-shaped chute 8 along axis direction, the following clamp 2-2 of snak link 2 is arranged in the chute 8 movingly, also comprises one group of pressing plate 6 with installing hole 5, and two side lower parts of keel 2 have the draw-in groove 3 that connects pressing plate 6, one end of pressing plate 6 has the flanging 6-1 corresponding with draw-in groove 3, and the flanging 6-1 of pressing plate 6 is stuck in the draw-in groove 3.Snak link 2 is made by spring steel, and can slide in chute 8.

As shown in Figure 1, the bottom center of described chute 8 is provided with convex tendon 1-1 along axis direction, and the following clamp 2-2 of snak link 2 is bearing on the convex tendon 1-1.Adopt this structure can avoid installing in the wooden tongue-and-groove joint floor process, because chute 8 is darker, snak link 2 is fallen into the inconvenience that is brought in the chute 8.

As shown in Figure 5, the installing hole 5 on the pressing plate 6 is the oval hole, is convenient to adjust the installation site.

Shown in Fig. 1,3, the cross section of the draw-in groove 3 of 1 liang of side lower part of keel is " レ " shape.This structure is convenient to realize the clamping of pressing plate 6 and keel 1, and is rational in infrastructure, quick for installation, and can dismantle at any time.

The used keel of the utility model can adopt the plastic-steel material to make, and have not only guaranteed the intensity of keel, and can be a large amount of forest reserves of country's saving.

Installation process of the present utility model is as follows: when laying wooden tongue-and-groove joint floor, lay earlier moisture sealer on the ground, again keel 1 are placed on the moisture sealer through levelling, the following clamp 2-2 of snak link 2 is packed in the "T"-shaped chute 8 of keel 1, wooden tongue-and-groove joint floor 7 intersections are placed on the keel 1, the last clamp 2-1 of snak link 2 is placed two adjacent installations joint close behind the raised line of piece grooved and tongued floor and the seam crossing between the groove bottom that looses, the both sides of diffusing piece grooved and tongued floor can be on snak link 2, following clamp 2-1, under the acting in conjunction of 2-2, and be fixed in tightly on the keel 1.Flanging 6-1 with pressing plate 6 snaps in the draw-in groove 3 of keel 1 then, with screw 4 pressing plate 6 is fixed on the ground, and again keel 1 is fixed on the ground by pressing plate 6, can effectively prevent the upper and lower motion after grooved and tongued floor 7 pressure-bearings, has eliminated noise.

The utility model connects with cassette and replaces iron nail, can make floor free wxpansion and indeformable warpage, is convenient to installation and removal renovation, the permanent use again.
