Abstract

On one side of every rectangular floor board, along its length direction an inward recessed groove is cut, on the correspondent position of another side of said floor board an outward tongue is set, the forms, sizes and positions of said recessed groove and tongue must be adapted, between two floor boards the inlaying joint of recessed groove and tongue can be used for forming locking fastener. The lower groove edge of the recessed groove is extended outward and toward oblique upper direction to form hook tongue, and lower tongue edge of the tongue is extended inward and toward oblique upper direction to form hook groove, the forms, sizes and positions of hook tongue and hook groove must be adapted. Said invention utilizes the inlaying joint of recessed groove and tongue and inlaying joint of hook tongue and hook groove to make the floor boards be firmly and tightly combined together.

Description

Floor joint fastening grooving

Technical field

The present invention relates to a kind of paving structure of floor, be specifically related to a kind of adjacent two floor joint fastening groovings that floor slice is bolted together.

Background technology

Existing floor lock button tongue and groove can roughly be divided into two classes, and flat push type is installed by tongue and groove and the embedding of bottom surface formation miter angle presses down the installation tongue and groove again.The installation of these two kinds of floor tongue and grooves all need could be installed by instrument, and is very high to the ground flat degree requirement, and the high low head in 3 square metres of scopes can not surpass 3 millimeters, and at present at the premises in China, ground is impossible realize to this requirement almost.And the tensile strength of flat push type tongue and groove is also lower, the highlyest just can reach 500kg/lM, can not satisfy market demand.

Summary of the invention

Low in order to overcome existing floor lock button tongue and groove tensile strength, the deficiency that installation requirement is high the objective of the invention is to: a kind of floor joint fastening grooving is provided, and this floor joint fastening grooving is produced easy, easy construction, and tensile strength is very high.

The technical solution adopted for the present invention to solve the technical problems is as follows:

A kind of floor joint fastening grooving, it comprises the square floor of two lengths of a film, side on each square floor of length of a film, and below end face, inwardly have groove along its length direction, outwards be provided with tenon at another side opposite position place on this sheet floor, the shape of groove and tenon, size and position are all suitable, between two floors by groove and tenon inlay the formation snap close, two floors are combined closely; The following trough rim of described groove outwards and obliquely upward extends, and forms a hook strips tenon; Inwardly and obliquely upward extend on the following tenon limit of described tenon, forms the hook groove one, and the shape of this hook groove and hook tenon, size, position are all suitable.

Compared with prior art, the invention has the beneficial effects as follows:

1, installs simply, need not other instrument.

2, has very high tensile strength

Mating formation of floor of the present invention is to inlay by the groove between adjacent two floors and tenon to form, and is provided with the hook tenon in groove ends, has the hook groove at the tenon end.When the splicing laying floor, tenon is embedded in the groove, the hook tenon also is embedded in the hook groove simultaneously, realize dual-inlaid, and, they be subjected to force direction opposite, constraint restriction mutually, make between floor slice to be closely linked securely, the whole floor tensile strength that is laid to is improved, can reach 1000kg/lM.

3, applicable to irregular ground

Since between floor slice of the present invention in conjunction with firmly, make be laid to after, the floor integral rigidity strengthens, not yielding subsiding, thereby make it can be used for irregular ground.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

Figure 1 shows that floor joint fastening grooving of the present invention an embodiment, it comprises two identical rectangle floor slice I1 and rectangle floor slice II2, side on each square floor of length of a film, and below end face, inwardly have groove 4 along its length direction, another side opposite position place on this sheet floor outwards is provided with tenon 3, groove 4 is all suitable with shape, size and the position of tenon 3, between two floors by groove 4 and tenon 3 inlay the formation snap close, two floors are combined closely.In the present embodiment, groove 4 is a rectangular recess, and its outwards also extension obliquely upward of trough rim down forms a hook strips tenon 6; Described tenon 3 is and groove 4 corresponding rectangle tenons, and it inwardly and obliquely upward extends on tenon limit down, forms hook groove 5 one, and this hook groove 5 is all suitable with shape, size, the position of hook tenon 6.The hook of hook tenon 6 top is pointed shape in the present embodiment, and the bottom land of hook groove 5 with matching is corresponding pointed shape.

For the ease of installing, and to allow some leeway in order expanded with heat and contract with cold in the floor, to fall an oblique angle respectively laterally along its length direction, make adjacent both sides, bottom surface, two floors, splicing back form a bottom V-type groove 7 in the both sides, bottom surface on each square floor of length of a film.

Making of the present invention and installation process are as follows:

With specification respectively for 1288mm * 194mm * 8mm rectangle floor slice I1 and two semiproduct floor slices of rectangle floor slice II2 put the floor fluting apparatus into and slot, side on the square floor of every length of a film is left tenon 3 and hook groove 5 along its length direction, leave groove 4 and hook tenon 6 at another side, be processed into the joint fastening grooving floor.See also shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, during installation, the tenon 3 of a slice rectangle floor slice I1 is embedded another length of a film squarely in the groove 4 of plate II2 by certain angle, simultaneously, hook tenon 6 also embeds in the hook groove 5, for hook tenon 6 is embedded in the hook groove 5 smoothly, have a dummy notch 8 in hook groove 5 inboards.Then with rectangle floor slice I1 to the level of pressing to, and concordant with rectangle floor slice II2, two floor slices closely are interlocked, promptly finished two and be adjacent to mating formation of plate.Analogize in proper order, the floor slice that all are adjacent carries out identical installation, can finish mating formation of required large tracts of land floor shown in Figure 2.Floor covering layers among Fig. 2 are on the ground 9 of injustice, and the floor still keeps level straight.
