Electric heating floor blank based on CLT (Cross-Laminated Timber) board and manufacturing method thereof

Abstract

The invention discloses an electric heating floor blank based on a CLT (Cross-Laminated Timber) board and a manufacturing method thereof. The electric heating floor blank comprises a base plate layer (1) and a thin plate layer (4), wherein the base plate layer (1) is a CLT board formed by vertically and horizontally stacking and gluing a plurality layers of single wood boards in a crossed manner; a plurality of grooves (3) are formed in the upper surface of the base plate layer (1); the length directions of the grooves (3) are parallel to the length direction of the uppermost single wood board laminated and stacked in the CLT board of the base plate layer (1); a heating film (2) is placed in each groove (3); the thin plate layer (4) made from valuable timber sheets further covers the base plate layer (1). The manufacturing method comprises the following steps: milling a plurality of grooves on one surface of the CLT board, placing the heating films inside the grooves, and covering the grooves with the valuable timber sheets. Compared with an ordinary solid wood compound electric heating floor, the solid wood compound electric heating floor manufactured by utilizing the method has high stability, and power failure and blank deguming and cracking generated by cracking of the heating films after long-time use are avoided.

Description

technical field

[0001] The invention belongs to the technical field of floor manufacturing in the wood processing industry, and more specifically relates to an electric heating floor blank and a manufacturing method thereof. Background technique

[0002] Most of the traditional solid wood composite floors are laminated with multi-layer solid wood veneers or spliced ​​with single-layer finger-jointed boards to make core boards. After long-term use, it has been found that the solid wood composite floor made of these core boards may have the disadvantages of internal stress and processing stress, large deformation, unevenness, and poor bending resistance, or due to the use of a large amount of adhesives, the environmental performance of the product is poor. Bending and deformation are not easy to control, the pass rate is low, and the production cost is high.

[0003] CLT board is a new technology product of wood structure developed in recent years. Its full name is cross-lami...
