Embodiment 1

[0030] as Figure 1 As shown, a wood connection method using the dry shrinkage rate of wood, comprising a first wood piece 1 and a second wood piece 2, the first wood piece 1 taken from hardwood, the second wood piece 2 taken from coniferous wood (cork), the dry shrinkage rate of the first wood piece 1 is greater than the dry shrinkage rate of the second wood piece 2, comprising the following steps:

[0031] Step 1: Dry the first wood piece 1 and the second wood piece 2 respectively, drying to the same moisture content;

[0032] Step 2: On the first wood piece 1 and the second wood piece 2 are opened the same connection port 3 and the connection block 4, the connection port 3 and the connection block 4 have the same shape;

[0033] Step 3: Connect the first wood piece 1 with the second wood piece 2 through the connection port 3 with the connection block 4;

[0034] Step 4: Dry the connected first wood piece 1 with the second wood piece 2.

[0035] The method described in the prese...

Embodiment 2

[0037] as Figures 2 through 6As shown, a wood dryer for drying the wood parts connected using the method described in Example 1, comprising a drying cadre 5, the drying cadre 5 comprising a mounting table 51, a drying table 52 and a base 53, the base 53 is provided above the chute 531, the mounting table 51 is disposed within the chute 531, the drying table 52 is fixed above the mounting table 51, the drying table 52 includes a drying plate 521, a support column 522 and a transmission 523, Support column 522 and transmission parts 523 are provided between the drying plate 521 and the mounting table 51, the bottom of the drying plate 521 is provided with a transmission groove 5211, the transmission 523 includes a transmission wheel 5231 that can be combined with the transmission groove 5211, the transmission part 523 is connected by the transmission wheel 5231 and the transmission groove 5211 and the drying plate 521 transmission, the drying plate 521 is set into a ring, the suppo...

Embodiment 3

[0043] The difference between the present embodiment and Example 2 is that: the drying tray 521 is provided with a sensor 5212 for detecting the moisture content of the wood.

Abstract

The invention relates to the technical field of wood connection, in particular to a wood connection method utilizing wood drying shrinkage, comprising a first wood piece (1) and a second wood piece (2), and combining the first wood pieces ( 1) Dry to the same moisture content as the second wood piece (2), and then respectively set up connection ports (3) on them, and then dry again after connecting through the connection ports (3). Due to the different dry shrinkage rates, the cork The dry shrinkage rate is larger and the degree of deformation is larger, so the connection between the first wood piece (1) and the second wood piece (2) will be clamped, so as to achieve the purpose of connection and fixation. This method uses the physical properties of wood The characteristics make the connection fixed, no drilling and other connecting parts are required, and the original dryer in the factory can be used for wood drying to achieve the purpose of reducing costs.

Description

Technical field [0001] The present invention relates to the field of wood joining technology, in particular to a wood joining method using the dry shrinkage rate of wood. Background [0002] At present, China's building structure main materials concrete, steel, brick masonry, etc. are high energy-consuming materials, the situation forces us to look for more energy-saving and environmentally friendly building materials, wood into the line of sight of choice, in Western developed countries, wood structure is the main form of residential housing, a large demand for wood also stimulates the development of forestry. North America in order to meet their own needs at the same time, but also a large number of exports of wood to other countries, which for the development of modern light wood structure system architecture in China to create good conditions, wood due to the limited natural size, or the needs of structural structure, and with splicing, length and node connection and other m...
