The anti-corrosion pine sylvestris is also widely used in the construction of outdoor wood structure landscape, outdoor wood ware, anti-corrosion wood floor, wood structure house construction, etc. As a modern wood structure, glulam has obvious advantages.
The processing and production can be prefabricated in the factory, which saves time and can be reused in the future. Low carbon and environmental protection, green environmental protection, energy saving, shock resistance and durability, and healthy and comfortable. A glulam building differs from a reinforced concrete building in that a solid piece of wood will scorch, but not burn.
If you remove the charring, you'll still have a solid structure, and when a concrete building fires, the rods in the concrete can expand and cause the concrete to explode. For steel, fire will melt it. It can avoid the influence of knots and cracks in the wood, carry out reasonable grading, use the amount of wood, and improve the wood utilization rate and material strength.
The boards or small squares with parallel wood grains are firstly terminated or edged in the length or width direction to form laminates, and then laminated and glued wood materials in the thickness direction.
