DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0019] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited to the embodiments.

[0020] As shown in the drawings, Figs. 1-3 The cantilevered steel type safety protection suspended ceiling system provided in the embodiments of the present application includes a support steel 1, a top plate suspended ceiling 2, a bottom surface suspended ceiling 3 and a vertical surface suspended ceiling 4. One end of the support steel 1 (cut from an I-beam) is installed on an outer wall 5. The top plate suspended ceiling 2 (cut from a flame-retardant polymer plate, mainly used for preventing large falling objects and playing a fireproof role in fire operation) is installed on the top of the support steel 1 through a batten 13 to form an upper hard closed layer, and the batten 13 is used for bearing the upper closed layer. The bottom surface suspended ceiling 3 is installed on the bottom of the support steel 1. The vertical surface suspended ceiling 4 is installed vertically on the other end of the support steel 1.

[0021] In the present application, the top plate suspended ceiling 2 is cut from a flame-retardant polymer plate. The bottom surface suspended ceiling 3 and the vertical surface suspended ceiling 4 have the same structure, which includes an aluminum alloy keel 14 and a PVC composite plate 15 installed between the keels. The above structure forms a double-layer three-dimensional protection system of "upper template hard closed layer + lower suspended ceiling flexible protection", so as to intercept falling objects of different particle sizes, solve the problems that the traditional single-layer protection net cannot effectively intercept falling objects of different particle sizes (large volume objects penetrate the upper layer, and small stones penetrate the lower layer), and the safety hidden danger of cross operation is large, and achieve the technical purpose of realizing hierarchical interception (preventing large volume falling objects in the upper layer, and filtering small particles in the lower layer). The use shows that the protection suspended ceiling system provided in the present application improves the high-altitude falling object interception efficiency by 80%, and reduces the accident rate by 90%.

[0022] Further, as shown in the drawings, Figs. 1-3As shown, in this invention, the left and right adjacent bottom ceiling 3s are connected by pins (the front end of the bottom ceiling 3 is equipped with a first pin 10 (U-shaped pin), the rear end of the bottom ceiling 3 is equipped with a first pin hole 11, and the left and right adjacent bottom ceiling 3s are fixedly connected by the first pin 10), and the front and rear adjacent bottom ceiling 3s are connected by hinges 6, and EPDM elastic sealing strips 7 are installed between the front and rear adjacent bottom ceiling 3s to prevent rainwater leakage; the above structure can effectively solve the problems of air leakage, dust leakage, and poor airtightness caused by wind pressure deformation in traditional protective splicing structures, and achieve the technical effect of achieving a composite protection ventilation rate of ≤15%, a dust concentration reduction of 70%, reducing the risk of deformation caused by wind vibration, and isolating construction dust from hazardous sources.

[0023] In this invention, a U-shaped buckle 9 is installed on the supporting steel 1 by bolts 8, and one or both ends of the bottom ceiling 3 are installed in the standardized U-shaped slot on the clamp 9.

[0024] Furthermore, such as Figs. 1-3 As shown, in this invention, the vertical ceiling 4 is installed on the external bottom ceiling 3 by the second pin, and the vertical ceiling 4 is vertically installed on the bottom ceiling 3 by the tightening screw buckle 12.

[0025] This invention employs a weld-free U-shaped buckle clamp (compatible with 16#-20# I-beams) connected to a standardized U-shaped slot, and U-shaped pins / pin holes for assembly. Combined with a tightening screw buckle to adjust verticality, it solves the problems of traditional welding / cutting installation damaging the I-beam structure, low reusability (<30%), and time-consuming disassembly and assembly (8h / layer). It achieves the technical effect of weld-free and cut-free non-destructive installation, increasing single-cycle efficiency by 60% (shortening to 3h / layer), supporting ≥5 turnovers, and material loss rate <5%.

[0026] Engineering tests show that the protective ceiling system provided by this invention can achieve a saving of more than 40% of steel consumption in a single project, a material loss rate of less than 5% after 5 turnovers, a 90% reduction in the accident rate of falling objects from heights, a 70% reduction in dust concentration, and a 25% reduction in overall construction costs, which meets the technical effects of green building evaluation standards (GB / T 50378).

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
