During this time, I checked my friend's reply, and found that many friends are not very clear about the use of sharing ground concrete silo seams, so let's talk about the issues that everyone is more concerned about.
Ground concrete sub-chamber joint, also known as ground shrinkage joint, refers to a kind of linear gap left when the concrete floor is paved. The main functions of this gap are as follows:
1. Alleviate the shrinkage stress of the concrete floor: During the curing process of concrete, the ground will produce internal stress due to shrinkage, and if there is no suitable gap to release these stresses, it will lead to ground cracking. The setting of the ground concrete silo joint can effectively alleviate the stress caused by the ground shrinkage and reduce the risk of ground cracking.
2.Prevent the spread of cracks: Even if cracks appear on the ground, concrete cracks in the ground can help stop the expansion and spread of cracks. This linear gap can limit the crack to a certain range, reducing the impact on the overall ground.
3.Improve the aesthetics of the ground: the setting of the concrete sub-chamber joints on the ground can make the ground look more regular and beautiful, and at the same time, it can also reduce the appearance of cracks and maintain the overall aesthetics of the ground.
Extended description: The setting of ground concrete silo joints needs to consider many factors, including the shrinkage properties of concrete, the use environment and load requirements of the ground. Normally, the width of the ground concrete sub-chamber joint should be between 5-20 mm, and the depth is determined according to the thickness of the concrete and soil conditions.
In addition to the ground concrete compartment joint, there is also a gap called the ground concrete expansion joint, which is used to cushion and expand in the case of a large ground area and the need to accommodate large deformation. Both of these types of gaps are set to extend the service life of the concrete floor, reduce maintenance costs, and maintain the flatness and aesthetics of the ground.
Ground concrete sub-silo joint is an important technical measure in concrete ground construction, which can reduce ground cracking and maintenance costs while improving the service life and aesthetics of the ground, and is an indispensable part of concrete ground construction.
