DETAILED DESCRIPTION
[0016] The present application will be further described below in combination with the drawings and embodiments. Referring to Figure 1 The composite floor is one of the floors. However, the composite floor changes the natural structure of the floor material artificially to achieve a floor with certain physical properties meeting the expected requirements. The composite floor often refers to the reinforced composite wood floor and the solid wood composite floor in the market. The composite floor changes the natural structure of the floor material artificially to achieve a floor with certain physical properties meeting the expected requirements. Most of the existing floor heating solid wood composite floors have the problem of thermal deformation due to the concentration of expansion stress of wood after heating, resulting in warping and cracking of the floor. The traditional floor relies on the heat conduction of wood itself, and the heat transfer is slow, which is not conducive to the purpose of high heat conduction. In order to solve the above problems, a floor heating solid wood composite floor is proposed, which comprises a panel layer 1, a substrate layer 2 and a bottom layer 3 which are sequentially laminated and fixedly connected from top to bottom, The metal heat-conducting net 11 is embedded in the panel layer 1 along the thickness direction of the panel layer 1, and is located in the central plane of the panel layer 1 and parallel to the length direction of the substrate layer 2, and a plurality of expansion joints 21 not penetrating the thickness of the substrate layer are formed in the substrate layer 2; The right side of the substrate layer 2 is provided with a locking structure 4, the locking structure 4 comprises a mortise 42 formed in the right side and a tenon 41 provided on the side of an adjacent composite floor for cooperating with the mortise 42, the tenon 41 is protruded upward at the end to form a limiting boss 411, and the shape of the mortise 42 is complementary to the tenon 41 to realize three-dimensional engagement. The lower surface of the bottom layer 3 is fully covered with a composite moisture-proof aluminum film 31; a stable composite floor structure is formed by the panel layer, the substrate layer and the bottom layer arranged from top to bottom, and the heat conduction efficiency is improved by the metal heat-conducting net, and the thermal stress is released in time by the expansion joint, so that the problems such as floor cracking caused by thermal deformation are avoided, and the adjacent composite floors are tightly matched during installation by the locking structure, so that the problems such as falling off are avoided.
[0017] It should be noted that the metal heat-conducting net 11 (heat-conducting path) and the expansion joint 21 (stress release path) intersect but do not overlap in the composite floor to avoid weakening the structural strength.
[0018] Further, the metal heat-conducting net 11 is uniformly distributed in the panel layer 1 for connecting and guiding the upper and lower layers of the composite floor; the metal heat-conducting net 11 can maximize the heat conduction effect of the composite floor by being uniformly distributed.
[0019] In addition, the metal heat-conducting net 11 can be distributed in a diamond-shaped structure in addition to the distribution form in the embodiment, so that the structure can be used in some special environments, such as further improving the strength of the composite floor.
[0020] It should be noted that the top of the mortise 42 is concave upward to form a limiting clamping groove 421 with an arc, and the limiting clamping groove 421 cooperates with the limiting boss 411; the tenon 41 is orderly clamped by the mortise 42, and the clamping process is the installation process of the adjacent two floor heating solid wood composite floors, and two adjacent solid wood floors are used in the cooperation of the tenon 41 and the mortise 42 of the composite floor in the installation process, so further explanation is made here.
[0021] Further, the arc of the limiting slot 421 means that when the tenon 41 gradually enters the mortise 42, the limiting boss 411 is close to the limiting slot 421, and in order to ensure that the limiting boss 411 can enter the mortise 42, the limiting boss 411 has a certain deformable property, thereby ensuring that it can be horizontally clamped / fallen in the mortise 42 with small gap, and the limiting boss 411 can ensure the stability of the tenon 41 clamped in the mortise 42.
[0022] It is worth mentioning that the moisture-proof aluminum film 31 and the bottom layer 3 are fixed by hot melt adhesive bonding; the hot melt adhesive bonding can ensure the stable bonding of the bottom layer 3 and the moisture-proof aluminum film 31, and the setting of the moisture-proof aluminum film 31 can ensure that the entire floor heating solid wood composite floor will not be affected by moisture during the contact with the ground after installation, thereby ensuring that the heat conductivity of the entire composite floor is relatively well protected.
[0023] In addition, in order to further improve the overall structural strength of the composite floor, in the embodiment, the substrate layer 2 is composed of 5-9 layers of cross-laminated solid wood veneers, and the above structure is provided to resist the deformation of the floor heating thermal stress. When the wood is subjected to dry-wet / cold-hot alternation, different direction expansion stress will be generated, and the structure can effectively improve the deformation resistance and improve the overall heat conduction uniformity.
[0024] It should be noted that the expansion joint 21 is parallel to the surface layer veneer grain direction, and the transverse expansion stress is absorbed by the vertically textured veneer layer, and the expansion joint 21 only needs to release the residual stress.
[0025] In addition, the metal heat conducting net 11 is made of aluminum material.
[0026] It should be noted that the embodiments of the present application are illustrative rather than limiting, and therefore the present application is not limited to the embodiments described in the specific embodiments, and any other embodiments derived by those skilled in the art from the technical solutions of the present application also belong to the scope of protection of the present application.
