Wood floor without pressing strip and construction method

The invention relates to the technical field of wood floors, in particular to a batten-free wood floor and a construction method thereof. The batten-free wood floor comprises a concrete threshold stone and a wood floor body, a first keel is connected to the outer side of the concrete threshold stone, a second keel is arranged on the other side of the first keel, and the wood floor body is arranged on the first keel and the second keel. A wedging groove is formed in the upper end face of the first keel, a sliding clamping groove is formed in the bottom end of the wood floor body, a T-shaped wedging block is connected into the sliding clamping groove, the lower end of the T-shaped wedging block is arranged in the wedging groove, an inclined threaded hole is formed in the upper end face of the first keel, and a connecting bolt is arranged in the inclined threaded hole. The wood floor is provided with the first keel, the second keel, the wood floor body, the T-shaped wedging block, the wedging groove, the inclined threaded hole and the connecting bolt, it is guaranteed that the wood floor body is flush with the horizontal plane of a door passing brick under the condition that a wood floor pressing strip is not used, meanwhile, it is guaranteed that the wood floor body cannot deviate, and the installation flatness and wedging degree of the wood floor body are improved.
