Abstract
A floor with an integrally formed elastic keel comprises two board blocks and a keel; the keel is a hollow cross-shaped main rib which is formed by an aluminum alloy plate; a left base piece and a right base piece laterally extend on the lower portion of the cross-shaped main rib; auxiliary ribs extend on end portions of the left base piece and the right base piece; an elastic piece is arranged inside the hollow cross-shaped main rib; two ends of the elastic piece are formed in the opposite internal walls on the left side and the right side of the cross-shaped main rib; main rib insertion grooves and auxiliary rib insertion grooves are formed in the board blocks; the cross-shaped main rib and the auxiliary ribs are inserted into the matched main rib insertion grooves and the auxiliary insertion grooves in the two board blocks; the upper surface of the cross-shaped main rib is exposed out from the two adjacent board blocks. The floor with the integrally formed elastic keel can effectively avoid bulging and deformation between the two adjacent board blocks and reducing contraction joint gaps between the two adjacent board blocks.
Description
Technical field:
The utility model relates to technical field of floor, more specifically to a kind of floor with elastic keel.
Background technology:
As shown in Figure 1, there is on the market at present a kind of floor, its two adjacent plank piece A1 link together by negative and positive groove A13 and keel A2, keel A2 has main muscle A21 and auxiliary muscle A22, in main muscle slot A11 and auxiliary muscle slot A12 that main muscle A21 and auxiliary muscle A22 sleeve match on plank piece A1, its weak point is: 1, in the time of plank piece bulking, between two adjacent plank pieces, can produce larger lateral stress, this stress easily causes plank piece arch camber distortion.2,, when after the shrinkage of plank piece, easily see the larger contracting seam gap of generation between two adjacent plank pieces on plank piece surface.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and the floor with one-body molded elastic keel is provided, and it can effectively prevent two adjacent plank piece arch camber distortion, reduces the contracting seam gap between two adjacent plank pieces simultaneously.
Technology solution of the present utility model is as follows:
There is the floor of one-body molded elastic keel, comprise plank piece and keel, keel are shaped to the cross main muscle of hollow by an aluminium alloy plate, be extended with left egative film and right egative film in the lower, transverse of cross main muscle, be extended with auxiliary muscle in the end of left egative film and right egative film, shell fragment is placed in the cross main muscle of hollow, and two ends of shell fragment are molded over respectively on the relative inwall of left and right two sides of cross main muscle;
On plank piece, form main muscle slot and auxiliary muscle slot, in cross main muscle and auxiliary muscle slot matches on two adjacent plank pieces respectively main muscle slot and auxiliary muscle slot, the upper surface of cross main muscle exposes between two adjacent plank pieces.
Described shell fragment is arc-like sheet, " U " font or " V " font.
On described cross main muscle, form vertical tenon, in the vertical slot that vertical tenon slot matches on plank piece.
The top of described cross main muscle is shaped to a recess, and shell fragment is an opening to arc-like sheet down.
The beneficial effects of the utility model are:
1, it can effectively prevent two adjacent plank piece arch camber distortion, reduces the contracting seam gap between two adjacent plank pieces simultaneously.
2, it can directly be transmitted to floor surface by underground heat, and logical thermal source in the hollow bulb of keel, can be to indoor heating.

Detailed description of the invention:
Embodiment: see shown in Fig. 2 to 5, there is the floor of one-body molded elastic keel, comprise plank piece 1 and keel 2, keel 2 are shaped to the cross main muscle 21 of hollow by an aluminium alloy plate, be extended with left egative film 22 and right egative film 23 in the lower, transverse of cross main muscle 21, be extended with auxiliary muscle 24 in the end of left egative film 22 and right egative film 23, shell fragment 25 is placed in the cross main muscle 21 of hollow, and two ends of shell fragment 25 are molded over respectively on the relative inwall of left and right two sides of cross main muscle 21;
On plank piece 1, form main muscle slot 11 and auxiliary muscle slot 12, in cross main muscle 21 and auxiliary muscle 24 slot matches on two adjacent plank pieces 1 respectively main muscle slot 11 and auxiliary muscle slot 12, the upper surface of cross main muscle 21 exposes between two adjacent plank pieces 1.
Described shell fragment 25 is arc-like sheet, " U " font or " V " font.In Fig. 2,3,4,5,6, just the shape of shell fragment 25 is different, and remainder structure is identical, and in Fig. 2, shell fragment 25 is " U " font, and in Fig. 3, shell fragment 25 is arc-like sheet.
Embodiment 2, as shown in Figure 6, forms vertical tenon 21a on described cross main muscle 21, in the vertical slot 13 that vertical tenon 21a slot matches on plank piece 1.All the other are with embodiment 1.
Embodiment 3, as shown in Figure 7, the top of described cross main muscle 21 is shaped to a recess 21b, and shell fragment 25 is an opening to arc-like sheet down.All the other are with embodiment 1.
Embodiment 4, as shown in Figure 8, the top of described cross main muscle 21 is shaped to a recess 21b, and shell fragment 25 is " U " font shell fragment.All the other are with embodiment 1.
Embodiment 5, as shown in Figure 9, described left egative film 22 and right egative film 23 are separately fixed on two back-up blocks 26, and two ends of shell fragment 25 are separately fixed on two back-up blocks 26, on back-up block 26, form hollow bulb.All the other are with embodiment 1.
Operating principle: because keel of the present utility model have elasticity, in the time of adjacent two plank piece bulkings, after acting on elastomeric keel, the huge lateral stress producing between two adjacent plank pieces is eliminated, so plank piece is difficult for arch camber distortion.
In the time of the shrinkage of plank piece, having flexible keel can laterally stretch to some extent, has just in time filled up the contracting seam gap between adjacent two plank pieces, so it reduces the contracting seam gap between two adjacent plank pieces.
Logical thermal source in the main muscle 21 of keel 2 or the hollow bulb of back-up block 26, can be to indoor heating.
