Strengthening method of beam column slab component

Concrete beams and slab members are the most widely used structural members in the current project. The flexural members of beams and slabs are strengthened by insufficient bearing capacity, including two aspects of the positive and inclined section.

How to thickening concrete beams by post installed anchor

Beam thickness strengthening method must ensure that the new and old concrete has higher bond strength. The main points are as follows: the base course of the original component joint surface should be solid, the surface is rough and clean, the shrinkage stress of the new cast concrete is small, and the bond performance is good.

Structural Strengthening for Bridges

Although there are many ways to strengthen the bridge and improve the bearing capacity of the bridge, the basic principles are all the same, and all of them follow the basic principle of mechanics. From the angle of external factors and internal conditions of bridge structure to strengthening for improving the bearing capacity.

Main reasons of cracking in the concrete members

According to the investigation data, the cause of structure cracking in engineering practice is about 80% of the cracks caused by "deformation" or cracks caused by "deformation" as the main factor, and about 20% of the cracks caused by the "load" factors.
