Building blocks are called square blocks, also known as wooden blocks, building blocks, construction engineering blocks, mouth materials, formwork supports, square block supports, etc. Each place has a different name. According to the actual needs of the construction site, the logs are cut into square strips of certain specifications and shapes, which are used for formwork support on construction sites. The formwork support in structural construction plays a role in fixing the formwork and wood used for house decoration.
Building blocks have strong nail holding ability and are suitable for construction projects, but not all types of building blocks are suitable for engineering. The commonly used types of building timber in construction projects include: camphor pine building timber, fir building timber, larch building timber, white pine building timber, etc.
The role of building wood in construction projects
Its application in construction engineering refers to the use of building blocks as corrugated wood for concrete formwork in civil engineering, which serves to reinforce the formwork.
In residential decoration, building blocks are commonly used as wooden keels, including in floor decoration, playing a very important role. In terms of construction, square timber is used as the material for the roof and keel pillars. In addition, building blocks are often used as the backbone of many furniture items.
Architectural square timber not only maintains the natural color of wood, but also is practical and durable, which is highly favored by people. It has made significant contributions to the construction project, fully realizing its value and playing a good role.
Selection method:
In home decoration, the production of wooden blocks accounts for a large part, so the selection of wooden blocks is particularly important. The selection of high-quality wood has a significant impact on the quality of home decoration. Therefore, when purchasing wooden blocks, careful selection should be made and quality should be emphasized. A moisture content of 8% to 12% is suitable for wooden blocks, as it will not cause cracking, warping, or other phenomena during use. Usually, the moisture content of wooden blocks is related to the drying method used. The steam drying effect is very good, and there are instruments available for testing. In addition, there are some simple and feasible methods:
1. Hand weight method: You can weigh the wooden blocks by hand, and those with higher moisture content are definitely heavier.
2. Hand touch technique: Place your hand on a wooden square and feel its humidity.
3. Knocking method: You can try using long nails to drive into the wooden square. If it is easy to nail, it indicates that the wood is relatively dry; Otherwise, the humidity will be relatively high.
4. Shake method: The finished wood can be shaken forcefully from one end. If the quality is not up to standard, it is easy to fall in half from the middle.
5. Eye observation method: How many knots does a wooden block have from beginning to end? If the scar is black, it cannot be used. It is easily damaged during installation.
