Abstract

An arch-preventing and shrinkage-crack-free floor comprises wood board blocks (1) and a keel (2), wherein main ribs (21) and auxiliary ribs (22) are formed on the keel (2); main rib slots (11) and auxiliary rib slots (12) are formed in the wood board blocks (1); the main ribs (21) are inserted into the main rib slots (11); the auxiliary ribs (22) are inserted into the auxiliary rib slots (12); a main rib transverse gap (1-21) and an auxiliary rib transverse gap (1-22) are respectively reserved between each wood board block (1) and the corresponding main rib (21) of the keel (2) and between each wood board block (1) and the corresponding auxiliary rib (22) of the keel (2); the upper parts of the main ribs (21) extend to form a shielding cap (23); the shielding cap (23) covers the surfaces of the two adjacent wood board blocks (1); and a shielding cap gap (1-23) is reserved between the lower part of the shielding cap (23) and each wood board block (1). The wood floor is effectively prevented from being arched; and moreover, the shielding cap is arranged on the surfaces of the two adjacent wood board blocks, people cannot see the gap between the two wood board blocks, and then a shrinkage-crack-free effect is achieved.

Description

A kind of floor of anti-arch shrinkage crack-free

Technical field:

The utility model relates to technical field of floor, more specifically to a kind of floor of anti-arch shrinkage crack-free.

Background technology:

As shown in Figure 1, a kind of clever button floor is arranged at present on the market, form main muscle A21 and auxiliary muscle A22 on its keel A2, form respectively main muscle slot A11 and auxiliary muscle slot A12 on two adjacent plank piece A1, main muscle A21 sleeve is in main muscle slot A11, and auxiliary muscle A22 sleeve is in auxiliary muscle slot A12.Its weak point is: 1, when the bulking of floor, can produce very large compressive stress between two adjacent plank piece A1, cause the arch camber of plank piece.2, when the shrinkage of floor, can produce larger slit between two adjacent plank pieces.

The utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and a kind of floor of anti-arch shrinkage crack-free is provided, and it can effectively prevent the wood flooring arch camber, there is shielding cap on two adjacent plank piece surfaces simultaneously, allow the people can't see two slits between the plank piece, form the contraction joint-free state.

Technology solution of the present utility model is as follows:

A kind of floor of anti-arch shrinkage crack-free, comprise plank piece and keel, form main muscle and auxiliary muscle on the keel, main muscle slot and auxiliary muscle slot on the plank piece, main muscle sleeve is in main muscle slot, auxiliary muscle sleeve is in auxiliary muscle slot, leave respectively main muscle transverse slot and auxiliary muscle transverse slot between the main muscle of plank piece and keel and the auxiliary muscle, main muscle top elongation moulding has shielding cap, block cap on the surface of adjacent two plank pieces, shielding cap bottom and plank interblock leave the shielding cap slit, and the shielding cap lower width is less than main muscle width.

Form horizontal small lugs on the described main muscle, keel have hollow bulb.

Form horizontal auxiliary muscle small lugs on the described auxiliary muscle, keel have hollow bulb.

The beneficial effects of the utility model are:

It can effectively prevent the wood flooring arch camber, and there is shielding cap on two adjacent plank piece surfaces simultaneously, allow the people can't see two slits between the plank piece, forms the contraction joint-free state.

Description of drawings:

Fig. 1 is the structural representation of prior art

Fig. 2 is the structural representation of embodiment 1

Fig. 3 is the structural representation of embodiment 2

Among the figure: 1, plank piece; 11, main muscle slot; 12, auxiliary muscle slot; 2, keel; 21, main muscle; 211, small lugs; 22, auxiliary muscle; 221, auxiliary muscle small lugs 221; 23, shielding cap; 1-21, main muscle transverse slot; 1-22, auxiliary muscle transverse slot; 1-23, shielding cap slit;

The specific embodiment:

Embodiment 1: as shown in Figure 1, a kind of floor of anti-arch shrinkage crack-free, comprise plank piece 1 and keel 2, form main muscle 21 and auxiliary muscle 22 on the keel 2, main muscle slot 11 and auxiliary muscle slot 12 on the plank piece 1, main muscle 21 sleeves are in main muscle slot 11, auxiliary muscle 22 sleeves are in auxiliary muscle slot 12, leave respectively main muscle transverse slot 1-21 and auxiliary muscle transverse slot 1-22 between the main muscle 21 of plank piece 1 and keel 2 and the auxiliary muscle 22, main muscle 21 top elongation mouldings have shielding cap 23, shielding cap 23 covers on the surface of adjacent two plank pieces 1, leaves shielding cap slit 1-23 between shielding cap 23 bottoms and the plank piece 1, and shielding cap 23 lower width are less than main muscle 21 width.

Embodiment 2: as shown in Figure 2, form horizontal small lugs 211 on the described main muscle 21, keel 2 have hollow bulb 2a.All the other are with embodiment 1.

Embodiment 3, as shown in Figure 3, form horizontal auxiliary muscle small lugs 221 on the described auxiliary muscle 22, and keel 2 have hollow bulb 2a.All the other are with embodiment 1.

Operating principle: when the bulking of floor, leave the slit that allows distortion between plank piece and the keel, like this when plank piece 1 bulking broadens, the compressive stress between two adjacent plank pieces has just in time been eliminated in this slit, so plank piece 1 can arch camber.

Shielding cap 23 has been covered with plank piece 1 surface, allows the people can't see two slits between the plank piece, forms the contraction joint-free state.
