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.

A pop-up book is essentially a three-dimensional, movable or folding book, although there are many other subcategories, including transformations, volvelles, tunnel books, flaps, pull-tabs, pop-outs and pull-downs. That`s quite the list of technical terms for the simple yet intricate task of immersing the reader, or rather the observer, in a story.
What are the pouring measures for beam-column nodes?
At present, grouting materials are widely used in the world for the installation of mechanical equipment and reinforcement repair projects. The technical performance of grouting materials in China is gradually increasing, and the price of grouting materials is also accepted by people. Beam-column node grouting material pouring In the ordinary circumstances, in order to facilitate the construction, it is possible to negotiate with the designer that the grouting material at the beam-column node is cast together with the beam. The specific measures are as follows;
