Description
Technical Field
The invention relates to the technical field of modular buildings, in particular to a grouting connecting node for a steel modular building.
Background
In recent years, modular construction of building structures has received great attention from the construction industry due to its many advantages over traditional construction methods, including: the construction process is faster and safer, the predictability of the completion time is better, the quality is better, fewer field workers, less resource waste and lower sensitivity to the environment. Modular buildings are made up of components and units (called modules) that are factory-made off-site, transported and assembled on-site to form the entire building.
In modular buildings, the connections between the modular units play a very important role, as they guarantee the structural integrity, the overall stability and the strength of the whole building. While a welded connection may provide rigidity between adjacent modules, this type of connection is generally not used on a job site because it requires high skill, requires a large amount of space, and is time consuming to inspect after welding. The existing inter-module connection technology of modular steel buildings can be divided into three different types: 1. connection between modules using tie bars, 2 connection between modules using connectors, and 3 connection between modules using bolts. The above-described inter-module connection technique does not require field welding, but still requires highly skilled labor and working space, and is not suitable for inter-module connection of modular steel buildings.
Therefore, there is an urgent need for a grout joint for steel modular construction to solve the problems existing in the prior art.
