The difference between the design of concrete structure reinforcement and the design of new concrete

The design of concrete reinforcement and the design of new concrete structures are different and are different codes.

The concrete reinforcement design code is GB50367, and the concrete structure design code is GB50010, which is essentially different.

And in the reinforcement design, the reinforcement methods include concrete replacement method, steel cladding method, bamboo charcoal fiber pasting method, and rear ring beam structural column method.

First of all, there is a difference in the durability of the material, because there is a large gap between the material of the reinforced body and the reinforced material in the molding time, the reinforced material must bear a heavier load than the original body. We know that the force is transmitted to the strong place, so the reinforced component must have more energy surplus than the new structural component.

Secondly, to ensure a good connection between the old and new concrete, it is necessary to excavate part of the old concrete.

1. There are several methods for reinforcing concrete structures.

1. Strengthen the concrete by paving the steel plate; 2. The strength of concrete is low, and the concrete can be replaced for reconstruction; 3. Construct on the outside of the concrete, add external prestress, and reinforce; 4. Weld the plate to improve the bearing capacity; 5. Use fiber composite board to reinforce concrete; 6. Increase the cross-section of concrete.

Second, what do you need to know about concrete construction?

1. In the process of concrete entering the mold, it is necessary to control the dosage and try not to pour it all at once, otherwise it is easy to bring unnecessary trouble. Generally is to impact the inside of the formwork first, pour the concrete of about 2m height, pay attention to the position of the outlet simultaneously, let the height of its pouring layer, control within, avoid the existence of safety hazards.

2. When the concrete is mixed, try to use it up within 4 hours, if it exceeds this time, it is easy to lead to cold joints in the concrete, which affects the strength of the concrete. Moreover, the time of concrete pouring needs to be controlled above, and the vibrator is stirred at the junction to enhance its strength.

3. During the pouring of concrete, it is necessary to constantly stir the vibrating rod until the concrete surface is no longer bubbled, and there is no floating slurry on the surface, then the concrete can be used. In addition, after the concrete is poured, it is necessary to roughly estimate the amount to see if it is necessary to continue, so as to contact the relevant personnel in time for arrangement.

There are several methods for reinforcing concrete structures, and what you need to know about concrete construction, so let's introduce it here. There are many ways to reinforce concrete structures, and it is best to carry out construction by professionalism, so as to avoid detailed problems and affect the subsequent construction.
