Modular geothermal floor

Abstract

The invention discloses a modular geothermal floor which comprises a bottom plate, a base material and a surface plate which are sequentially arranged from bottom to top. The base material is providedwith a plurality of frame units which are bonded on the bottom plate. Each frame unit comprises a rectangular frame, a metal thermal conduction net arranged at the inner bottom of the rectangular frame and a cover plate arranged at the inner top of the rectangular frame. The surface plate is bonded with the top faces of the cover plates and the top faces of the rectangular frames. The modular geothermal floor is simple in structure and convenient to mount and has the excellent thermal conductivity and stability.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a modular geothermal floor. Background technique [0002] Geothermal floor refers to the wooden floor suitable for laying of ground radiation heating system, and the heat is transferred to the living room through the board. Due to the large fluctuations in humidity in the four seasons of the geothermal environment, the climate in the northern heating period is dry in winter, the moisture content is about 4-5%, the lowest indoor relative humidity is about 30%, and the summer moisture content is about 12-13%, the equilibrium moisture content of the floor It is only 6%-7%, and the moisture content of the floor changes by about 8% a year. The main types of flooring currently on the market are: solid wood flooring, engineered wood flooring and laminate flooring. Solid wood flooring and solid wood composite flooring are favored by people because of their good touch, sound insulation, ...

AI Technical Summary

Problems solved by technology

[0003] The solid wood floor has the following defects: 1. Due to the anisotropy of the wood and the swelling and shrinkage of the wood, the floor cracks, and the largest gap can reach 3-5mm; 3. The floor is easily deformed, and the degree of deformation is also related to the width. In a dry and hot environment, due to the special fiber structure of wood and the tendency to produce Warping and twisting, the larger the aspect ratio, the more obvious the deformation; 4. Solid wood is a poor conductor of heat, the heat conduction is slow, the heat storage is good but the heat conductivity is poor, the heat on the ground is transferred to the surface through the floor, and the heat loss is relatively small Big; 5. After some solid wood floors are processed, sawing deformation grooves are set at the bottom of the floor, and its function partly disperses the change of stress, which reduces the heat conduction efficiency

The floor surface layer of multi-layer solid wood composite flooring is relatively thin veneer, and the base material is equivalent to multi-layer plywood. In an environment with low humidity, the drying shrinkage of the surface layer is much greater than the drying shrinkage of the base material. Synchronous phenomenon, the surface board and the base material produce tensile stress at the same time to ensure the same width, resulting in surface cracking, and the three-layer solid wood composite floor will also have inconsistent drying shrinkage due to the different anti-deformation capabilities of the three layers, resulting in transverse ripples on the board surface and cracking

For the stability problem, the wood fiber pores are usually dense and concentrated through the carbonization mode, and all organic matter is decomposed and denatured, which eliminates the internal stress of the wood, and no longer swells and shrinks when it is wet. It can prevent moisture and corrosion to a certain extent, and improve the overall stability. However, with the change of carbonization temperature and time, the floor loses the original elasticity of the wood, and the material becomes brittle, which cannot solve the problem of thermal conductivity of the geothermal floor.
