Description

Technical Field

[0001] The utility model relates to the technical field of suspended ceiling support structures, in particular to a woodworking suspended ceiling counter-support structure. Background Art

[0002] Large-space public buildings such as auditoriums, theaters, banquet halls, lobbies, conference halls, etc. have a common feature of high height, large span, long hangers, and more equipment pipelines in the ceiling. During the ceiling construction process, if the height of the ceiling hanger exceeds 1.5m, a ceiling counter-support must be set. Carpentry ceiling counter-support refers to the construction of the carpentry ceiling.

[0003] In order to increase the stability and load-bearing capacity of the suspended ceiling, reinforcement measures for the suspended ceiling structure are usually taken. Counter-support is achieved by adding beams, diagonal braces or other supporting components to the suspended ceiling structure. However, this method is more troublesome during actual installation. During actual installation, the inclined grooves need to be welded or fixed with bolts, which makes the installation more difficult. At the same time, the space occupied by this structure in actual use will also be larger, which makes transportation or installation more troublesome. Therefore, the above problems need to be solved.
