Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, in particular to a ceiling for a maintenance opening in a large space. Background Art

[0002] When equipment installed on the ceiling breaks down and needs repair, the ceiling can be directly entered through the inspection port, making repair work more convenient and quick. At the same time, when ventilation ducts are installed in the ceiling, they need to be cleaned and maintained regularly. If there is no inspection port, the ceiling needs to be dismantled for maintenance, which is too inefficient.

[0003] The method of making inspection openings is mostly to use wood or T-shaped keels to make inspection openings on site. This method makes the inspection openings easy to be damaged, cracked and deformed, protruding outside, and the specifications and dimensions are not uniform, which prolongs the decoration period and affects the overall appearance. Another method is to use aluminum alloy profiles, galvanized iron plates, and spray-painted to complete the open-style inspection openings.

[0004] The defects of these methods are: 1. The existing inspection openings have large joints, which cannot close the ceiling space, and the closure and decorative properties are poor. 2. The inspection openings require a more complicated method of use, which is troublesome to open, and some inspection openings require special tools to open.

[0005] When installing large-span aluminum ceilings in large spaces such as commercial public areas, the air conditioning, fire protection, winch and other equipment inside the ceiling are complicated and require a large number of inspection openings. A large number of inspection openings lead to a large number of joints on the ceiling, which affects the structural strength of the ceiling and also greatly affects the overall appearance.

[0029] The Z-shaped keel 3 is a through-length member, and its top plate is fixed to the bottom end of the suspension rod by bolts.

[0030] like Figure 4 As shown, the closed ceiling 4 is a special-shaped long plate with folded edges on both sides, one side of the folded edge is a C-shape bent inwardly, and the other side of the folded edge is a Z-shape extending outwardly.

[0031] The Z-shaped folded edge of the closed ceiling 4 is fixed to the bottom end of the flame retardant board by self-tapping screws. The C-shaped folded edge of the closed ceiling is overlapped on the bottom end plate of the Z-shaped keel 3.

[0032] like Figure 5As shown, the inspection opening is a rectangular frame composed of four hollow rectangular short columns. The inspection ceiling 6 is a special-shaped long plate with C-shaped folded edges bent inward on both sides. Three inspection ceilings are arranged at the bottom of the inspection opening, and the folded edges of the inspection ceiling and the inspection opening are fixed by self-tapping screws.

[0033] The length and width of the inspection opening are both greater than the length and width of the three inspection ceilings arranged in an arranged manner.

[0034] During installation, the inspection opening is placed on the Z-shaped keel and the equipment belt ceiling from top to bottom, and the inspection ceiling below is tightly spliced ​​with the closed ceiling and the equipment belt ceiling. Black adhesive strips are set between the joints of each ceiling for top bonding, and the joints between each ceiling are extremely small.

[0036] like Figure 6 As shown, the adapter 7 is an L-shaped plate, and its horizontal plate is longer than the vertical plate. There are upward reinforcement plates on the front and rear sides of the adapter to strengthen the structural strength of the adapter. The top of the vertical plate of the adapter has a horizontally extending lap folded edge, and the end of the horizontal plate has an inverted L-shaped lap folded edge bent inward.

[0037] The vertical plate of the adapter is overlapped on the side of the light strip, and the horizontal plate of the adapter extends toward the inspection opening. The end overlap fold of the horizontal plate is overlapped with the Z-shaped keel limited by the suspension rod.

[0038] The inspection opening is placed on the Z-shaped keel and the equipment belt ceiling from top to bottom, and the inspection ceiling below is tightly spliced ​​with the adapter and the equipment belt ceiling. Black adhesive strips are set between the joints of each ceiling for top bonding.

[0039] like Figure 3 As shown, the inspection opening is located between the light strip and the smoke exhaust port, and the gap reserved between the two is larger than the size of the inspection opening to be installed and the inspection opening ceiling.

[0040] The hanging member 8 is a hollow rectangular short column. The hanging ceiling 9 is a short special-shaped plate with folded edges on both sides, wherein the folded edge on one side is S-shaped and the folded edge on the other side is Z-shaped extending outwards.

[0041] The hanging part 8 is fixed beside the adapter 7 through a hanging rod, the S-shaped folded edge of the hanging ceiling 9 is plugged into the adapter, and the hanging part, the hanging ceiling and the adapter are fixedly connected by self-tapping screws.

[0042] The smoke exhaust port is connected to its own smoke exhaust pipe and is suspended above the building space. A smoke exhaust port ceiling is arranged below it, and the folded edges at both ends of the smoke exhaust port ceiling are overlapped by hanging rods and Z-shaped keels and fixed by bolts.

[0043] The inspection opening is placed on the hanging ceiling and Z-shaped keel from top to bottom, and the inspection ceiling below is tightly spliced ​​with the hanging ceiling and the smoke exhaust port ceiling. Black adhesive strips are set between the joints of each ceiling for top gluing.

[0044] This product is used for the inspection opening ceiling in large spaces and is suitable for ceiling installation in various situations. During installation, the joints are extremely small, there is no exposed frame, and the decorative effect is good. At the same time, the inspection openings are mostly overlapped by various ceilings, without the need for a large number of keels, with a small overall mass and not easy to deform. At the same time, the inspection opening can be pushed up by a slight push upwards, which is convenient to open and easy to use.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
