The middle of the upper part of the keel is provided with a convex rib with a barb part and convex ribs distributed on two sides of the convex rib with the barb part, at least one inserting groove is formed on the keel, the cushion block consists of a main body part which has equal height with a keel cube and an inserting tenon matched with the inserting groove on the keel, and the inserting tenon on the cushion block is inserted in the inserting groove on the keel. In a fixer used with the locking catch block, one side of a block body is provided with a left groove, a right groove and a middle groove which are matched and sleeved with the left convex rib, the right convex rib and the middle convex rib of the keel respectively; and the left groove and the right groove are provided with flanges. The locking catch block can conveniently assemble a plurality of wood floor blocks together, the assembly is convenient and simple, and the wood floor is not easy to deform after assembling.

Description

technical field [0001] The invention relates to the technical field of floor keels, and more specifically relates to a combined locking floor keel component and an installation tool suitable for use on floors and wall panels. Background technique [0002] The traditional wooden floor is composed of wooden boards and keels. The adjacent two boards are matched by Yin and Yang grooves. The keel is usually made of square wooden strips. When using them, the wooden strips are nailed to the ground, and the wooden floor is nailed to the square wooden strips In fact, this is not only complicated to install, it is easy to damage the structure of the house, but it will also cause excessive stress on the wooden floor, which is likely to cause deformation of the wooden floor. [0003] Patent application number 200510019219.7 and announcement number CN1908341A disclose a combined locking floor joist. Such as figure 1 Shown is a structural schematic diagram of the connection between the ...

Problems solved by technology

[0004] 1. Keel B As the wooden floor users want the width of each wooden unit block to be as wide as possible, and to appear generous and decent, each wooden unit block A adopts a small unit type keel B according to figure 2 The way shown is to install and fix, obviously it cannot meet the requirements of making the wooden floor not deformed and firm

[0005] 2. At the same time, the wooden floor is still showing a thinner trend. Lock the buckle block B with a small unit, such as figure 2 The way shown is to install and fix, and there is no guarantee that the wooden floor will not be deformed
