Description

Wood floor core and sound insulation wood floor

Technical Field

The utility model relates to the technical field of wood floor cores, in particular to a wood floor core and a sound insulation wood floor.

Background

With the rapid development of socioeconomic performance, more and more occasions are increasingly concerned with noise requirements, such as sound insulation and deformation resistance of floors. When the existing floor has better deformation resistance, a plurality of layers of sub-board assemblies are adopted to form a core board in a conventional mode, and then the core board is compounded with an upper layer and a bottom layer to obtain the floor. The core board with the structure is formed by assembling multiple layers of sub boards, but because the wood grain of each sub board is consistent, when the width or length direction of the core board is stressed, the deformation resistance of the core board is not ideal, and a large deformation phenomenon exists. For example, chinese patent discloses a sound insulation timber apron chinese patent No. (CN 201922418785.5), a sound insulation timber apron from top to bottom includes wood layer, puigging and substrate layer in proper order, evenly be provided with a plurality of sections in the puigging and be arched supporting seat, supporting seat arched top with wood layer butt, the bottom of supporting seat with the substrate layer links to each other, between supporting seat and the supporting seat and in the supporting seat all fill and have sound insulation material. The scheme has the sound insulation effect and can not sink when the floor surface is used for a long time.

Although above-mentioned scheme is through setting up a plurality of arched supporting seats in the sound insulation layer, the top and the solid wood layer butt of supporting seat, and the bottom and the base plate layer of supporting seat link to intussuseption between supporting seat and supporting seat is filled with sound insulation material and is played good sound insulation effect, but not well solves above-mentioned technical problem, and the phenomenon of bending deformation still exists in the sound insulation timber apron, can't guarantee the planarization of acoustic celotex board bulk connection.
