What are the pouring measures for beam-column nodes?
Changchun Taiyuan fluoromica Co. Ltd. is located in Changchun high tech Industrial Development zone. It is a high-tech economic entity integrating scientific research, production and management. The company has a strong technical team. There are 1 senior experts and doctoral tutors who have been engaged in artificial lens research for more than 20 years, 1 postdoctoral researchers engaged in nonlinear control research, 1 researchers engaged in inorganic material research, and several senior engineers and engineers engaged in research of related specialties. Strong technical force has laid the foundation for the development of the company in the field of new materials.
To meet the needs of national industrial development, the company has been devoted to the research and development of fluorite mica and its products in 2004. The product is a new material with high temperature resistance, corrosion resistance, low dielectric loss, high volume resistivity, absorption of multi band beam and good transmittance of light. It is transparent, separable, elastic, aging and fragile. It is mainly used in the working environment of electric insulation, neutron test, high frequency medium, high temperature vacuum, high temperature and high pressure, strong acid and strong alkali. It can be used as a substitute for low performance materials such as polytetrafluoroethylene, natural mica and quartz glass.
Our company warmly welcome friends from all walks of life to visit, hope you know the fluorite mica and the use of fluorite mica. Our company will provide free test supplies for scientific research personnel in the high-tech field.

1. If the strength level of column grouting material exceeds the strength level of the grouting material of the slab greater than Grade II, and there are cast-in-place beams on all four sides of the column, the grouting material of the beam and beam nodes can be poured together with the beam.
2. If the strength grade of the column grouting material is one grade higher than the strength grade of the beam plate grouting material, the grouting material at the beam and beam node can be poured together with the beam.
If the above two conditions are not met, and you want to pour the grouting material at the beam-column node together with the grouting material of the beam plate, you can use the following measures;
1, increase the steel bars within the scope of the node 2, set the steel beam in the beam column node area, and the length of the steel beam should be not less than 250mm longer than the two sides of the column respectively.
3. Add longitudinal reinforcement in the node. The longitudinal reinforcement can be set around the pillar. It can also be made in the central area of ​​the node by using spiral steel reinforcement.
Some of the above measures are used;
1. Beam-column joints are grouting materials of the same strength grade, no separate pouring, no construction joints, no weak links, easy control, and reliable quality. The disadvantage is that it will increase engineering costs and increase the designer's workload.
2. Convenient construction can speed up the progress of the project and shorten the construction period.
