In addition to the professional design and installation of heating and air conditioning, the company has also adopted the integrated production, ventilation and maintenance mode of heating and air conditioning.
The influence of the knot on the flexural strength is closely related to the position of the knot on the section height of the member.
Twill is a common defect of wood, which is called twill or twist for short.
Our company is located in Pingquan City, Chengde, Hebei Province.
It is mainly divided into knots and oblique lines.
Let’s introduce the common diseases of wood structure heritage.
Let you realize your living ideal and the primitive ecological life of being close to nature and returning to nature.
We will sincerely await your inquiry and guidance.
The wood with pith core has serious cracks; The wood without pith core has slight cracks.
Therefore, when using wood, special attention should be paid to the direction of wood grain.
When making wood with low moisture content, the dry shrinkage crack is slight.
Generally, wood with high density is easy to crack because of its large shrinkage deformation.
Knots refer to the defects at the base of the branches surrounded by the trunk, which is a natural defect.
When making, the method of “core breaking and blanking” can be adopted to saw the wood from the pith core to obtain radial wood, reduce the internal stress during wood drying and shrinkage, and greatly reduce the possibility of cracks.
Knots in many cases will reduce the mechanical properties of wood, because knots destroy the uniformity and integrity of wood.
The closer the knot is to the tensile edge, the greater the influence is.
The strength anisotropy of wood is due to the existence of diagonal grain.
Twill will also make the plate easy to crack and warp, resulting in serious bending of the column.
The common diseases and defects of wood structure heritage are called wood defects, also known as wood defects, which lead to the change of normal wood material, the reduction of wood utilization value and even the complete inability of wood to use due to abnormal structure, or poor environment and other external factors.
Therefore, in addition to the professional design and installation of water supply and drainage, the company has also realized the high efficiency of building construction and decoration.

Dry shrinkage cracking the law of wood dry cracking is: generally, the cracks are radial, developing from the outside to the inside to the pith core.
Knots have the greatest influence on the tensile strength along the grain and the least influence on the compressive strength along the grain.
Due to the long-term wind and rain erosion and the destruction of man-made and natural disasters, the performance of materials and structures will inevitably weaken and damage.
During the drying process, wood deforms and shrinks due to water evaporation.

For example, the strength is very different due to the different angle between the action direction of force and the direction of wood grain.
Our company selects the best quality Russian Scotch pine and Canadian pine as raw materials to build the wooden structure house, which not only has natural material and low-carbon raw materials; Green health, energy conservation and environmental protection;; Stable structure and simple construction; It has the characteristics of anti-seismic, flame retardant, safety and comfort, and is durable, anti-corrosion, warm in winter and cool in summer, comfortable in four seasons, safe and solid fire and moisture prevention, anti-seismic, environmental protection and pollution-free, and practical landscaping.
With high-quality products, honest style and enthusiastic service, we look forward to creating a green, environmental friendly and humanistic living environment with you.
At present, our company has completed the construction works of large-scale projects such as scenic spots, municipal projects, community landscape, wood structure independent houses (villas) and has maintained long-term supply relations with foreign wood structure material suppliers such as Canada, the United States and Russia.
The existence of oblique texture reduces the tensile, compressive and flexural strength along the grain of wood.
It has modern standard workshop, professional production equipment, first-class technicians, unique production technology and world advanced anti-corrosion, insect proof, moisture-proof and flame-retardant treatment technology.
The greater the slope of texture, the greater the impact, as shown in the figure below.
And also engaged in anti-corrosion wood, carbonized wood, wood production, processing, manufacturing and sales.
When it is located in the compression area, the less the influence is.
Its main business is mobile wooden house, wooden structure house, wooden villa, heavy wooden house, light wooden house, garden viewing and other projects.
Zhanxin gardening wooden house construction expert (website: www.zxyybj.com contact: manager Lin Tel; 13801215992; 13501173599) is an enterprise integrating design, R & D, manufacturing and installation of wooden houses and wooden landscapes.
Drying shrinkage cracking is a common disease of wood structure heritage.
Our company adheres to the business and service philosophy of reputation first, people-oriented, quality first and continuous innovation.
The relationship between wood strength and twill angle.
From scheme design to construction, each step is customized for customers to build high-quality ecological wood structure buildings at a price satisfactory to customers.
is an enterprise focusing on wooden structure houses under Beijing Baohong Construction Project Management Co., Ltd.
