Recently, I found that many people do not know much about the model of the bottom steel bar, if you also want to know what's going on, you can take a look at this introduction below.
A sub-rebar sub-silo joint is a reserved gap in the ground or underground structure that is used to separate and adjust the length of concrete components. It can absorb the deformation and stress caused by shrinkage and temperature changes in concrete, thereby reducing the risk of concrete cracking and failure. It is important to have an in-depth understanding of the type of sub-silo joint of the sub-rebar and its maintenance and upkeep to ensure the stability and service life of the structure.
The bottom reinforcement sub-silo joints are mainly divided into the following types:
1. Conventional joint: Conventional joint is a common type of sub-silo joint of the underlying steel bar, and its width is equal to the thickness of the concrete component. It is usually filled with rubber or polymer material to guarantee the flexibility and tightness of the gap.
2.Elastic joints: Elastic joints are composed of metal strips, rubber pads, or polymer materials and have a large stretching capacity. It can absorb a wider range of concrete shrinkage and deformation caused by temperature changes, and has better waterproof performance.
3.Steel Plate Seam: A steel plate seam is made up of two steel plates, which are connected together by bolts or welds. It has high stiffness and strength, making it suitable for places that require a large load carrying capacity.
In daily maintenance and upkeep, the following precautions are required for the sub-silo joints of the underlying reinforcement:
1. Regular inspection: Regularly check the state of the sub-silo joints of the underlying steel bars, including the width of the gap, sealing and surface wear. If damage or looseness is found, it needs to be repaired or replaced in time.
2.Cleaning and maintenance: keep the bottom steel bar compartment joints clean, and remove dust, debris and stagnant water in the cracks in time. This helps prevent clogging and corrosion of crevices.
3.Supplementary maintenance materials: If the filling material of the sub-silo joint of the bottom reinforcement is aged or damaged, the maintenance material should be supplemented in time to ensure the elasticity and sealing of the gap.
4.Avoid excessive load: set up protective plates or identification plates on the joints of the bottom steel bars to avoid excessive load on vehicles or heavy objects, resulting in damage and deformation of the gaps.
5.Temperature control: In an environment with large temperature changes, measures should be taken to control the temperature of concrete components to reduce the impact of shrinkage and expansion on the sub-silo joints of the underlying reinforcement.
It is an important step to ensure the stability and service life of the concrete structure by in-depth analysis of the type of sub-silo joint of the bottom reinforcement, and to carry out maintenance and maintenance. Measures such as regular inspection, cleaning and maintenance, timely repair and supplementary maintenance materials can effectively extend the service life of the sub-silo joints of the underlying steel bars and ensure their normal function and performance.
