Problems solved by technology

[0002] Before the present invention, the structure of the keel was mostly a hollow skeleton, and the upper end surface of the hollow skeleton had convex edges with the two side walls, and the card was mounted on the upper end of the hollow skeleton, and was clamped with the two side walls. The defects of its existence were: 1. When the floor is damp and arched, the card will fall off or break due to excessive force, so the keel is not strong and durable; 2. Because its structure is too complicated, installation is inconvenient, time-consuming and labor-intensive, and the cost is too high

Abstract

The invention relates to a metal wood floor keel with card and pothook types, characterized in that it comprises keel and card; said keel is groove and between the upper face of it and side wall is T-shaped; said card is i-section and pothook is set on the upper face with parallel to the upper face of keel, the cervix of card is clipped at the upper face of groove. The invention is provided with following merits that 1, improving the phenomenon that the floor arches and falls off easily when it is affected with damp and it is firm and durable; 2, assembling expediently, saving labor and shortcutting, assembling with many methods, good foot feeling after assembling, economic and wide application.

Description

technical field [0001] The invention belongs to keels, in particular to a card-hook type metal wood floor keel. Background technique [0002] Before the present invention, the structure of the keel was mostly a hollow skeleton, and the upper end surface of the hollow skeleton had convex edges with the two side walls, and the card was mounted on the upper end of the hollow skeleton, and was clamped with the two side walls. The defects of its existence were: 1. When the floor is damp and arched, the cards are overstressed and cause falling or breaking, so the keel is not strong and durable; 2. Because its structure is too complicated, installation is inconvenient, time-consuming and labor-intensive, and the cost is too high. Contents of the invention [0003] The object of the present invention is to provide a card hook type metal wood floor keel, which overcomes the above-mentioned defects, changes the phenomenon that the floor is easy to fall off or break when the floor is...
