CROSS-REFERENCES

This application claims benefit of US provisional patent serial No. 63/738,584, filed on December 24, 2024, the contents of which is incorporated herein by reference in their entirety.

TECHNICAL FIELD

This disclosure relates generally to construction, and modular construction in particular.

BACKGROUND

Traditional building construction methods usually result in errors that reduce the strength, size, and precision of multi-storied buildings. As a result, it is common for traditionally-constructed buildings to have deformations, failure of building modules to connect, slabs cracking, and difficulties to close doors and windows.

As such, the modular construction system is desirable because of the generally reduced costs and higher precision. The higher precision reduces the errors in the resulting building and improve the chance of successful module connections.

SUMMARY

The present disclosure provides a connection system for efficiently and securely connecting modular construction units. The system includes a first connection plate with a locator hole for receiving a connection pin and a bolt hole for receiving a connector. A second connection plate with a corresponding bolt hole is provided, allowing the two plates to be connected via the connector passing through their respective bolt holes. A spacer with locator holes can be positioned between the first connection plate and a third connection plate that also has a locator hole, enabling connection pins to pass through and connect the plates and spacer. Extensions on the plates allow connection to adjacent parts. This modular connection system facilitates rapid assembly and disassembly of the construction units for various applications.
