Problems solved by technology

[0002] Traditional wooden floor keels usually use square wooden strips. When in use, the wooden strips are nailed to the ground, and the wooden floor is nailed to the square wooden strips. This is not only complicated to install, but it is easy to damage the structure of the house, and it will also make the wooden floor If the stress is too large, it is easy to cause deformation of the wooden floor

Embodiment 1

[0019] Embodiment 1: Refer to Fig. 1 and Fig. 4 . The keel 1 of the present invention is rectangular, on one side of the surface of the keel 1 there is a longitudinal main rib 2 with a T-shaped cross-section; 4. On the surface of the keel on both sides of the transverse main rib 4, at least one, or two or more transverse auxiliary ribs 5 parallel to the transverse main rib 4 may be arranged on each side.

[0020] In this embodiment, the transverse main ribs 4 and the transverse auxiliary ribs 5 are arranged side by side and have the same length. The cross section of the lateral auxiliary rib 5 is a raised boss, and the surface of the raised boss is arc-shaped.

[0021] The present embodiment is installed at the joint of three boards, as shown in Figure 4. When installing, first splice the transverse seams between two adjacent plates 6, insert the transverse main ribs 4 and transverse auxiliary ribs 5 in the keel 1 into the corresponding grooves of the plates 6, and then inse...

Embodiment 2

[0022] Embodiment 2: Refer to Fig. 2 and Fig. 5 . The keel 1 described in this embodiment is rectangular, and a longitudinal main rib 2 with a Γ-shaped cross section is provided on one side of the surface of the keel 1. On the keel surface on both sides of the longitudinal main rib 2, one is arranged on each side, and two can also be arranged. Or a plurality of longitudinal auxiliary ribs 3 parallel to the longitudinal main ribs 2; on the other side of the keel surface, a transverse main rib 4 with a T-shaped cross-section perpendicular to the above-mentioned longitudinal main ribs 2 and longitudinal auxiliary ribs 3 is provided, and two sides of the transverse main ribs 4 On the surface of the side keel, each side is provided with one or two or more transverse auxiliary ribs 5 parallel to the transverse main ribs 4 .

[0023] In this embodiment, the longitudinal main ribs 2 and the longitudinal auxiliary ribs 3 are arranged side by side and have the same length; the transvers...

Embodiment 3

[0025] Embodiment 3: refer to image 3 and Figure 6. The structure and usage method of this embodiment are basically the same as those of Embodiment 2, except that the cross-section of the longitudinal main rib 2 of this embodiment is T-shaped.

[0026] In the above embodiments, nail holes for fixing the keel can be provided in the vertical direction of the keel 1 so that the keel can be nailed to the ground, wall or top surface. The keel 1 can be set in different thickness series to facilitate the adjustment of the floor height. The cross-sections of the longitudinal auxiliary ribs 3 and the transverse auxiliary ribs 5 can be T-shaped, Γ-shaped, rectangular, triangular, arc-shaped, polygonal, etc., or raised bosses whose surface is arc-shaped. It can be set on one side of the main reinforcement, or on both sides, or not. Which one to use depends on the installation position of the plate.

Abstract

The invention relates to an integrated lock buckle floor keel, which is characterized in that: one edge of keel has one longitudinal main bar; anther end has the transverse main bar vertical to the longitudinal one; at least one of the left and right side walls of longitudinal and transverse main bars has one protruded edge. The inventive keel can lock the longitudinal and transverse joints between two nearby plates at the same time, to avoid slit between them, to improve the mounting quality.

Description

technical field [0001] The invention relates to a floor keel, in particular to a combined locking floor keel suitable for use on floors and wall panels. Background technique [0002] Traditional wooden floor keels usually use square wooden strips. When in use, the wooden strips are nailed to the ground, and the wooden floor is nailed to the square wooden strips. This is not only complicated to install, but it is easy to damage the structure of the house, and it will also make the wooden floor If the stress is too large, it is easy to cause deformation of the wooden floor. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned background technology, and propose a combined locking floor keel that can make the installation of wooden floors and wall panels convenient and fast, with good installation quality and no deformation or warping. [0004] In order to achieve the above object, the present invention ad...
