Many people have recently paid more attention to the practice of double-layer two-way steel bar sequential joints, due to today's abundant time, the following we have prepared a relevant introduction, I hope to help you.
Double-layer two-way reinforcement sub-silo joint refers to the sub-silo joint of two layers of longitudinal steel bars and two layers of transverse steel bars in the concrete structure, the purpose of which is to prevent cracking caused by temperature and shrinkage in the concrete.
Set location and spacing requirements:
1. Location: In general, the double-layer two-way steel bar sub-silo joints are set in the stress concentration area of the concrete structure, such as the corner of the column and the wall, the junction of the beam and column, etc. These locations are susceptible to temperature and shrinkage, so it is necessary to set up a bin seam.
2.Spacing requirements: The spacing of the sub-bin seam should be calculated according to the size and design requirements of the specific structure, and the following aspects can be generally referred to:
a.Structure size: The spacing of the sub-silo joints can be determined according to the size of the structure, and it is generally recommended to set the sub-silo joints at 1 3 places that do not exceed the small size of the structure to ensure the overall force balance of the structure.
b.Material properties: The spacing of the sub-silo joints should also take into account the material properties of concrete and steel bars to ensure the strength and stability of the concrete structure.
c.Temperature and shrinkage: The spacing of the silo seam should also consider the temperature and shrinkage of the structure to ensure that the silo seam can play a role in alleviating cracking.
Discussion angle: 1. Structural stability: Double-layer two-way steel bar silo joints can effectively disperse the force of concrete structure, reduce the internal stress caused by temperature and shrinkage, and improve the stability of the structure.
2.Prevents cracking: Splitting joints can reduce cracking in concrete structures because it relieves internal stresses caused by temperature and shrinkage, allowing the concrete to be more evenly distributed when stressed.
3.Economy: Reasonable setting of sub-silo joints can reduce the maintenance and repair costs of concrete structures, and at the same time prolong the service life of the structure.
4.Engineering construction: In the construction process, it is necessary to set up the silo joints in strict accordance with the design requirements to ensure that the position and spacing of the silo joints meet the requirements to avoid construction quality problems.
5.Concrete quality control: Reasonable setting of silo joints can improve the quality control of concrete structures, as it can reduce the problem of cracking in concrete, thus ensuring the overall stability of the structure.
6.Follow-up maintenance: The setting of the sub-silo joint also facilitates the subsequent structural maintenance and overhaul work, as it can provide easy access for inspection and repair.
The setting position and spacing requirements of double-layer two-way steel bar sub-silo joints in concrete structures are very important, which can effectively prevent the cracking problem of concrete structures and improve the stability and service life of the structure. Therefore, in the design and construction process, the above elements need to be fully considered to ensure that the setting of the sub-silo joint meets the actual needs.
