To build a wooden house, you must first choose the right materials. A good wooden house mainly depends on the choice of wood when building a wooden house. At present, there are two types of wood suitable for building wooden houses.

hardwood

and

cork

First, hardwood-the classification of wood for building wooden houses mainly includes the following categories:

1, oak

Appearance: the wood grain is straight, and the structural pores are medium or thick;

heartwood

Light brown,

sapwood

Narrow and almost white;

tangible property

Hard material, high strength and toughness; Excellent wear resistance, generally not.

warping

Deformation, good steam bending performance; Heartwood is very durable.

Machinability: Machinability and Red

oak

Similar, but more easily broken; Good turning performance and difficult manual processing;

nail

Good tenon joint performance, although the pores need to be filled with fillers before processing; The adhesion performance is satisfactory; Easy coloring and surface treatment, smooth effect can be obtained without special surface filling; Long-term contact with metals will lead to dark color;

2、

Carya cathayensis

wood

Appearance: dense texture, generally straight wood grain and rough structure; Heartwood is light or reddish brown, sapwood is white.

Physical characteristics: heavy material, hardness, strength, seismic performance,

crushing strength

Very high; Good durability, difficult deformation and low corrosion resistance.

Machinability: turning performance and machinability are good, but

hand tool

Processing difficulties;

viscose

Good tenoning and nailing performance; Good coloring performance, and good glossy surface can be obtained after sanding.

3、

Ash genus

Appearance: the texture is straight and the structure is even. Heartwood is grayish brown and sometimes red.

Physical properties: the bending properties of wood are different, but overall it is good. When steaming wanqu, the stitches are easy to fall off. This kind of wood has high strength, elasticity,

impact toughness

Hardness is better in similar balsa wood, especially the impact toughness is excellent.

Machinability: tool wear is moderate, and wood is easy to be processed by hand. When nailing on hardwood, it is necessary to drill holes in advance. ligneous

come to a deadlock

Sex, skin color and

Polishing performance

Everything is fine.

4、

Acer wood

Appearance: the wood grain is straight, the texture structure is fine, and the texture is even and delicate; The sapwood is almost white, red in some cases, and the heartwood is light brown.

Physical properties: high weight, high hardness, high strength and high toughness; Medium impact resistance, low corrosion resistance and average durability; The steam bending performance is satisfactory.

Machinability: good machinability and outstanding turning performance, but easy to predict, irregular texture may cause fragmentation; Before nailing and tenoning, it is recommended to fill the pores with fillers; Good adhesion, smooth surface after treatment.

5、

birch

Appearance: generally straight, the texture is tight and uniform, and some textures are staggered. The heartwood is light brown or dark brown red, and the sapwood is nearly white.

Physical properties: heavy and hard material, high strength and good seismic performance; Easy deformation and poor corrosion resistance.

Machinability: easy to machine with mechanical tools, but difficult to machine by hand; Warp is easy to occur, so it is best to fill the pores with fillers before fixing with nails and glue. Good surface can be obtained by dyeing and polishing.

Second, cork-wood classification For the construction of wooden houses, there are mainly the following types:

1、

fir

Appearance: the wood grain is basically straight and very uniform, with medium or thick structure; Heartwood is white or yellowish brown, and the boundary with sapwood is not obvious;

Physical properties: light, soft and average hardness; Low strength, poor seismic performance and poor corrosion resistance;

Machinability: good manual or mechanical machinability and easy turning; Excellent gluing, nail holding and tenoning performance; Good coloring, painting and polishing performance;

2. Pinus ponderosa

The sapwood is white, the heartwood is light brown, the texture is dense, the resin is less and hard. In North America, it is used in buildings, sleepers and plates, and it is one of the important timber trees. Resistant to barren and drought.

3. Larix gmelinii

Larch wood is heavy and solid, with high compressive and bending strength, corrosion resistance and high technological value. It is an excellent material for poles, sleepers, bridges, columns, vehicles and buildings. At the same time, because deciduous pine trees are tall and straight, the crown shape is beautiful, the root system is very developed and the smoke resistance is strong.

4. engelmann spruce, alpine fir and black pine

Engelmann spruce, black pine, high fir. The main characteristics of SPF: good strength.

Light weight, high stability, easy drying and stable size,

The coating has good coloring and adhesion, easy processing and strong nailing force. Sun protection coefficient

After kiln drying, the moisture content is below 19%, which makes the strength and toughness of wood reach the best level, which not only strengthens the ability of moisture-proof and insect-proof, but also is more stable, not easy to crack and beautiful for a long time. Mainly used for corner materials of compartments, indoor wiring boards, splicing boards, tongue-and-groove wallboard, diagonal beams or structural materials, bookshelves, laminates, indoor wallboard, etc.

The above two kinds of wood have their own advantages and disadvantages when building wooden houses, so it is necessary to choose suitable wood according to geographical environment and many objective conditions.
