The aluminum veneer not under the bottom duct hanger 1 can be fixed using a conventional aluminum veneer keel support structure, which will not be repeated here.

[0053] Therefore, the utility model is an aluminum single plate ceiling structure specially used for the bottom of the air duct. By adopting the utility model, the bottom air duct hanger and the main keel are avoided through the left notch and the right notch, the left aluminum single plate and the right aluminum single plate are clamped by the secondary keel and connected to the main keel, and the left and right ends of the main keel are fixed to the structural member through ceiling hangers or other fixing parts, thereby optimizing the conventional aluminum single plate keel support structure in terms of the ceiling installation space, maximizing the net height of the bottom of the air duct, and being particularly suitable for situations where the on-site air duct cannot be adjusted and the ceiling is not allowed to be partially lowered.

[0054] The utility model can make full use of the space occupied by the original bottom duct hanger of the duct, and does not occupy other space except the thickness of the aluminum veneer. Therefore, compared with the conventional aluminum veneer ceiling structure, the net height can be increased by 50-150mm.

[0055] The advantages of the present invention are mainly reflected in the impact of the net height increase on the plan. For example, for certain projects with specified net height requirements, but the on-site difference is only 50-150mm, the use of the present invention can avoid the adjustment of the electromechanical pipeline layout plan, or the dismantling and modification of the site.

[0056] The main keel, the secondary keel, the left connecting piece and the right connecting piece of the utility model can all be assembled by bolts, and can be flexibly adjusted according to the on-site conditions, so on-site construction is relatively convenient.

[0057] In summary, the utility model of the combined aluminum single plate ceiling structure under the air duct can improve the height of the ceiling below the air duct, has a clever design, a simple structure, is easy to manufacture, has a low manufacturing cost, and is suitable for large-scale promotion and application.

[0058] It can be seen that the purpose of the utility model has been completely and effectively achieved. The function and structural principle of the utility model have been demonstrated and explained in the embodiments. Without departing from the principles, the implementation methods can be modified arbitrarily. Therefore, the utility model includes all modified implementation methods based on the spirit and scope of the claims.
