Abstract

The utility model discloses a can prevent warping laminate flooring, it is including the surface course of bamboo wood material, the laminating of surface course lower surface has the filling layer, wherein, the filling layer mould the piece by multi-disc plastic piece or stone and constitute, each plastic piece or stone are moulded and are had the clearance between the piece. The lower surface of the filling layer is attached with a buffer layer made of a soft material, and the lower surface of the buffer layer is attached with a non-setting adhesive and a release paper layer. And a transverse reinforcing rib is embedded in the middle of the filling layer. The plastic block or the stone-plastic block forming the filling layer is in a solid shape, a hollow shape or an irregular shape. The utility model discloses combine the surface course and the filling layer of bamboo wood material together for the floor when keeping floor grade sense, the consumption of the wood material that has significantly reduced is favorable to the environmental protection. And gaps are formed among the plastic or stone-plastic blocks forming the filling layer, so that the floor warping phenomenon caused by inconsistent coefficients of thermal expansion and cold contraction of the filling layer and the surface layer in the use process of the composite floor can be prevented.

Description

A laminate floor that resists warping

Technical field:

The utility model relates to the technical field of building decoration materials, in particular to a composite floor laid on the ground for use.

Background technique:

At present, the floors seen in the market are mainly divided into several types such as marble floors, plastic floors, and wooden (bamboo) floors. These types of floors have their own advantages and disadvantages. Among them, the wood (bamboo) floor has a high sense of grade, but it needs to consume a large amount of wood (bamboo) materials, which is easy to aggravate the damage to forest resources and is not conducive to environmental protection; secondly, the wood (bamboo) floor has poor bending resistance , If you do not pay attention during the construction process, it is easy to break, causing unnecessary waste; third, the wooden (bamboo) floor is relatively hard, lacks comfort, and has poor impact resistance and cushioning performance; fourth, the wooden (bamboo) floor The construction is difficult during laying, and it is easy to generate debris when it is lifted off the ground, which affects environmental sanitation.

Utility model content:

The purpose of this utility model is to provide a composite floor that can prevent warping in view of the deficiencies of the prior art. It has a high-grade sense, and at the same time, it will not warp and deform during use, and it is comfortable to use , Laying is convenient.

In order to achieve the above purpose, the warp-preventable composite floor of the present invention includes a surface layer made of bamboo and wood, and a filling layer is pasted on the lower surface of the surface layer, wherein the filling layer is made of a plurality of plastic blocks or stone plastics. There are gaps between each plastic block or stone plastic block.

The lower surface of the filling layer is laminated with a buffer layer made of soft material, and the lower surface of the buffer layer is laminated with a self-adhesive layer and a release paper layer.

The middle part of the filling layer is inlaid with transverse reinforcing ribs.

The plastic blocks or stone plastic blocks constituting the filling layer are solid, hollow, or irregular in shape.

The utility model has the beneficial effects that: it combines the surface layer and the filling layer made of bamboo and wood, so that the floor can greatly reduce the consumption of wood (bamboo) materials while maintaining the sense of floor quality, which is beneficial to environmental protection. There are gaps between the multiple plastic or stone plastic blocks that make up the filling layer, which can prevent the floor warping caused by the inconsistent thermal expansion and contraction coefficients between the filling layer and the surface layer during use of the composite floor.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Accompanying drawing 1 is the combination schematic diagram of the present utility model;

Accompanying drawing 2 is the exploded schematic diagram of one of the utility model embodiment;

Accompanying drawing 3 is the exploded schematic view of the second embodiment of the utility model.

Detailed ways:

The following descriptions are only preferred embodiments of the present utility model, and do not therefore limit the protection scope of the present utility model.

See accompanying drawing 1 and shown in accompanying drawing 2: composite floor of the present utility model includes surface layer 10, filling layer 20, buffer layer 30, self-adhesive and release paper layer 40. Wherein, the surface layer 10 is made of wood chips, wood chips, artificial wood, artificial bamboo and other materials. The filling layer 20 is attached to the lower surface of the surface layer 10 and is composed of multiple plastic sheets or stone plastic sheets added with stone powder. The presence of the filling layer 20 improves the strength and impact resistance of the product. Since the thermal expansion and contraction coefficients of the filling layer 20 and the surface layer 10 are inconsistent, in order to prevent the composite floor from warping during use, there is a certain gap between each plastic sheet or stone plastic sheet. The cushioning layer 30 is attached to the lower surface of the filling layer 20, and it is made of EVA, non-woven fabric and other materials, and mainly plays the role of cushioning and sound insulation. Self-adhesive and release paper layer 40 are attached to the lower surface of buffer layer 30, which can facilitate the laying of composite flooring.

As shown in accompanying drawing 3: two transverse bamboo reinforcing ribs 50 are inlaid in the middle of the filling layer 20 to increase the strength of the strip-shaped composite floor, and the rest are the same as the first embodiment.
