Construction technology and standards of new hollow plastic formwork foundation beam

When installing the foundation beam, we chose to use a new type of hollow plastic formwork for construction. This new type of formwork is lightweight and durable, and can improve construction efficiency and reduce costs, so it is very popular. Using this hollow plastic formwork for construction can not only improve work efficiency, but also reduce pollution to the environment, which is in line with the concept of sustainable development.

First of all, the installation of the foundation beam must be carried out after the soil at the bottom of the beam reaches the designed compaction degree. This is to ensure the firmness and stability of the foundation beam. Next, we use concrete (cement mortar ratio 1:3) for pouring. Concrete is a commonly used building material with high strength and good durability, which can provide solid support for the foundation beam.

After the concrete is poured, the hollow plastic formwork is installed according to the specific span requirements. For parts with small beam width, we will install the outer formwork, eject the two side lines at the cushion position, and then adjust the size and elevation of the formwork, and then support and fix it. This installation method can ensure the stability and accuracy of the formwork and lay a solid foundation for subsequent construction.

When the beam width is more than 4 meters, the construction personnel need to arch the bottom of the beam according to the ratio of 1/1000 to 3/1000 of the beam span, first the main beam and then the secondary beam. This arching method can effectively reduce the stress and deformation at the bottom of the beam and improve the stability of the beam. When adding pads, construction workers need to ensure that the spacing between support columns is 600 mm to 1000 mm, and use pads, shear braces and horizontal tie rods to reinforce the pillars to ensure the firmness and stability of the support. After the installation is completed, the construction workers must calibrate the elevation, size and beam centerline to ensure the quality and safety of the construction.

Such an installation method can not only ensure the stability and accuracy of the foundation beam, but also provide reliable support and guarantee for the construction of the project. The use of new hollow plastic formwork for construction not only improves construction efficiency and reduces costs, but also conforms to the concept of sustainable development, which has positive significance for promoting the development of the construction industry.

Through careful planning and rigorous construction, we believe that the installation of the foundation beam will provide a solid guarantee for the smooth progress of the entire project and lay a solid foundation for the stability and safety of the building. At the same time, we will continue to explore new building materials and construction technologies to make greater contributions to the sustainable development of the construction industry.
