Description

Technical Field

[0001] The present invention relates to the technical field of building decoration. More specifically, the present invention relates to a connection node structure and construction method for a ceiling conversion layer under a truss structure. Background Art

[0002] Currently, in large-space decoration projects, it is often encountered that the ceiling base layer is a truss and grid structure. The suspender cannot be fixed to the base structure alone, and a corresponding conversion layer often needs to be set in the ceiling to meet the fixing of the suspender, so as to meet the requirements of national codes.

[0003] Currently, the setting method of most truss structure conversion layers is to use steel frames for hoop binding, and weld steel frames between the hoop binding parts, arranged bidirectionally to meet the standard arrangement of ceiling suspenders. However, in actual use, there are still many disadvantages. For example, adopting this installation method will lead to a cumbersome installation process and there are areas for improvement. Therefore, we propose a connection node structure and construction method for a ceiling conversion layer under a truss structure to solve the problems raised in the background art. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a connection node structure and construction method for a ceiling conversion layer under a truss structure. Through the mutual cooperation of the first bolt, the second bolt, the chemical anchor bolt, and the adapter plate, prefabricated construction is realized, and further factory standardization and batch production are realized, thereby improving production efficiency. At the same time, prefabricated assembly is carried out at the construction site, which is convenient, fast, and further improves the construction efficiency and construction quality to solve the problems raised in the above-mentioned background art.
