Embodiment 1

[0025] Such as figure 1 , 2 , 3, 4, 5, and 6, a floor keel, comprising a strip keel body 1 with a rectangular cross section, one end of the keel body 1 has an upper lock head 1-1, and the other end has a lower lock head 1 -2, two adjacent keel bodies 1 can be fastened and connected with the lower lock head 1-2 of the other keel body 1 through the upper lock head 1-1 of one of the keel body 1; the upper lock head 1 The sum of -1 and the longitudinal thickness of the lower lock head 1-2 is equal to the longitudinal thickness of the keel body 1.

[0026] Such as figure 1 , 3 , 4, 5, and 6, in order to ensure that two adjacent keel bodies 1 are fastened together without gaps and firm, the upper locking head 1-1 of the keel body 1 has a transverse protrusion 1-1-1 and The longitudinal notch 1-1-2, the lower lock head 1-2 of the keel body 2 has a transverse notch 1-2-1 and a longitudinal protrusion 1-2-2; the transverse protrusion of the upper lock head 1-1 1-1-1 is fastened wi...

Embodiment 2

[0032] Such as Figure 7 , 8 As shown in , 9 and 10, a floor keel includes a strip keel body 1 with a rectangular cross section, one end of the keel body 1 has an upper lock head 1-1, and the other end has a lower lock head 1-2. The two adjacent keel bodies 1 can be fastened and connected with the lower lock head 1-2 of the other keel body 1 through the upper lock head 1-1 of one of the keel body 1; The sum of the longitudinal thicknesses of the lock heads 1-2 is equal to the longitudinal thickness of the keel body 1 .

[0033] Such as Figure 7 , 9 , 10, in order to ensure the fastness of the adjacent keel main bodies, the upper lock head 1-1 of the keel body 1 has a longitudinal notch 1-1-3, and the lower lock head 1-2 of the keel body 1 It has a longitudinal protrusion 1-2-3; the longitudinal notch 1-1-3 of the upper lock head 1-1 is engaged with the longitudinal protrusion 1-2-3 of the lower lock head 1-2.

[0034] Such as Figure 7 , 9 , 10, in order to further imp...

Abstract

The invention relates to a floor keel, which comprises a strip-like keel body with a rectangular cross section. One end of the keel body is an upper tapered end, and the other end of the keel body is a lower tapered end. Every two adjacent keel bodies can be connected by the upper tapered end of one keel body and the lower tapered end of the other keel body in a buckling way. The summation of longitudinal thicknesses of the upper and lower tapered ends is equal to the longitudinal thickness of the keel body. The floor keel provided by the invention has the advantages of buckling capability, buckled surface seamlessness and the like.

Description

technical field [0001] The invention relates to a floor keel, in particular to a floor keel for floor installation. Background technique [0002] Since the reform and opening up, due to the rapid development of the national economy, people have higher requirements for interior decoration. Most of the indoor floors must be paved with floors, and they are increasingly pursuing individuality. When paving floors, it is necessary to lay floor keels on the ground, and then install The floor is laid on the floor joist. The existing floor keels are cut to the required length according to the length of the room, and when the keel length is too long, it is difficult to carry. There are gaps between them, which are prone to looseness and instability, and it is time-consuming and laborious to pave. Contents of the invention [0003] The object of the present invention is to provide a floor joist that can be fastened and has no gaps on the surface after fastening. [0004] In order ...
