Building steel wood keel manufacture

  Steel wood keel is a new type of formwork product for building shear wall
Instead of the traditional steel pipe buckle reinforcement mode, it can be widely used in the construction of columns, shear walls and other parts
It has many economic advantages such as saving labor, materials and time, beautiful and tidy, and improves the safe construction and civilization of the construction site
Customization of high-strength steel and material configuration by designers not only simplify the construction difficulty, but also greatly improve the molding effect of concrete
The new steel clad wood shear wall reinforcement system can not only meet the reinforcement construction of ordinary shear wall in housing construction, but also has more obvious advantages in the reinforcement construction of super thick and super high shear wall
Advantages of steel wood keel: 1
Cost saving , The number of recyclable turnover times reaches more than 400, and the flat cost of the project is greatly reduced
2
High strength and stiffness , The average failure load of steel wood cube is 33217n, and the average flexural strength is 61
9pa, which is about 3 times and 5 times higher than that of traditional wood cube at the through interface The specifications of steel and wood squares are unified, and the layout drawing of steel and wood squares is deepened according to the construction drawings, which is convenient for construction, avoids a lot of on-site processing time and shortens the construction cycle
4
Environmental protection and energy saving , Steel and wood sides reduce the use of wood and protect monk forests- Secondary processing and forming can save energy; There is no on-site processing to protect the construction environment
5
Good molding , The specifications, models and dimensions of steel and wood squares are consistent, and the strength is higher than that of ordinary formwork
The deformation during construction is small
The flatness, perpendicularity, geometric size and flatness of internal and external corners of the poured concrete are beautiful Characteristics of traditional wooden square 1
High cost , The turnover times of timber are small and the residual value is unstable
In the later stage of the project, it needs to be repaired and lengthened manually, and the manual input is increased
2
Low degree and easy deformation , The traditional wood cube has small stiffness and no external beam
The wood cube is affected by moisture and is prone to deformation and warpage after water absorption
3
Large loss , During the construction process, the damage caused by workers' sawing and handling is irreversible
The damaged wood is difficult to reuse and achieve the expected turnover effect
4
Not environmentally friendly , About 1000 square meters of wood is required for every 100000 m3 building, and there will be a large amount of wood loss after the construction, resulting in damage to forest resources
5
Construction instability , The wood cube has large wet tension and dry shrinkage, low strength, low stiffness, and is easy to warp and crack Steel wood keel is a temporary support structure that makes the concrete structure formed according to pouring
It should bear the horizontal load (lateral pressure of concrete) and vertical load (self weight of building formwork, material structure and construction load) during the construction of concrete structure
The premise of using steel and timber is * * concrete engineering quality and construction safety, so that * * steel and timber has sufficient stiffness, bearing capacity and stability
Qualified raw materials and accessories must be strictly selected for the use of steel and wood cube, * * its own reliability is in line with the current reinforced concrete quality standards, and the splicing and processing of woodworking board and waste wood in the process of use must be stopped
