Enlarged section of cover beam
The reinforcement technology for the enlarged cross-section of the cover beam can be said to be a reinforcement technology for the protective structure of concrete. Concrete strength, stiffness and flexural strength. By increasing the cross-section and layout of the components, the stability and shear resistance of the components can also be improved, and cracks can be repaired. This reinforcement technology has been widely used in the reinforcement of plates, beams, and columns. According to the mechanical characteristics of the component, the requirements of the object, the geometric size of the component and the convenience of the structure, the foundation and the top plate can be designed to be wound on one, two, three or four sides.
The use of steel bars and steel bars are divided into cross-sections, steel bars or both to ensure the normal use of reinforced concrete. In order to place the steel bars reasonably and ensure the normal use of the steel bars, according to the structural requirements of the steel bars and the protective layer, the cross-sectional size has been increased. Combine new and old concrete.
The disadvantage of improving the segmented reinforcement technology is that there are many wet workers on site and a long maintenance period. This technique increases the size of the cross-section and sometimes affects the appearance and cleanliness of the house.
If you want to shorten the time, you can shorten the maintenance period to 3-7 days instead of tape. The construction period is tight, the section is small, and it is very convenient. The disadvantage is the high price. There are many types of irrigation materials and templates.
