Description

Technical Field

[0001] The invention belongs to the technical field of gymnasium brackets, and in particular relates to a multifunctional grid bearing device for an auditorium. Background Art

[0002] During the construction of the auditorium, the steel structure frame of the gymnasium is generally built using the structure of the prior art solution with patent number "CN201821909717.8" and patent name "A truss splicing steel structure frame for auxiliary installation of gymnasium ceiling suspension". During the truss splicing steel structure frame, the load-bearing beams, fulcrum beams, steel plates and other components in the truss are generally fixed together by welding to form the steel structure frame of the auditorium.

[0003] The steel structure frame of the auditorium is formed by welding together the load-bearing beams, support beams and steel plates in the truss, which is not easy to disassemble and maintain, and the difficulty of disassembly and maintenance is quite great.

[0004] On the other hand, in order to better illuminate the auditorium, it is often necessary to screw a transverse bearing body for carrying the lighting lamp on the upper part of the auditorium's pillars. The transverse bearing body is a bearing component used to laterally carry the lighting lamp. After the lighting lamp is installed on the transverse bearing body, the transverse and longitudinal curvatures of the lighting lamp can be changed by rotation. After achieving the optimal lighting direction and maintaining a constant state, constant lighting can be achieved.

[0005] Nowadays, the transverse bearing body often includes a load-bearing member, on which the main body of the lamp is installed. The main body of the lamp is installed after the approximate lighting range is changed. A semi-pearl-shaped light-transmitting safety shell with an open bottom that buckles the main body of the lamp is also installed on the load-bearing member. This is used to perform blocking protection on the entire main body of the lamp, thereby increasing the service life of the main body of the lamp.

[0006] However, when the transverse bearing body is installed on the upper part of the column of the auditorium, a large amount of particulate impurities are diffused in the air in the auditorium, and a lot of dirt will accumulate on the wall surface of the semi-beaded transparent containment with an open bottom, thereby hindering the lighting brightness of the main body of the lighting lamp and greatly reducing the lighting function. Summary of the invention

[0007] In order to solve the defects in the prior art, the present invention proposes a multifunctional grid bearing device for an auditorium, wherein the top wall of the column is connected to the ball head structure via a detachable connector, and the ball head structure is detachably connected to the lower wall of the ceiling of the auditorium and connects the trusses to form a grid-type steel structure frame of the auditorium, so that the components of this type of steel structure frame are detachable from each other, easy to disassemble and maintain, and easier to disassemble and maintain; a rotatable ratchet plate and a semi-beaded light-transmitting safety shell with an open lower portion fixed to the ratchet plate are provided on the load-bearing member. A descaling portion is provided on one side of the load-bearing member away from the camera area of ​​the main body of the lighting lamp, so that the semi-beaded light-transmitting containment shell with an open lower portion can be efficiently descaled without being detrimental to lighting; a water storage box is provided to supply deionized water to the descaling device, and the water supply timing is the same as the rotation timing of the semi-beaded light-transmitting containment shell with an open lower portion, thereby improving the descaling continuity and descaling function of the semi-beaded light-transmitting containment shell with an open lower portion; the movable strip is provided as a detachable and connected middle strip and side strip, so that the descaling device is more convenient to replace or maintain.
