Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, more particularly, to a seven-character corner. BACKGROUND

[0002] The seven-character corner refers to using a whole gypsum board to make an L-shaped cut at each corner of the suspended ceiling, rather than splicing two gypsum boards together. The main purpose of this is to prevent the expansion and contraction of the gypsum board from causing cracks at the corners in the future. Using a whole gypsum board increases material consumption, but greatly reduces the possibility of cracking at the top. However, even so, the corners of the gypsum board are still prone to cracking after long-term use. Since the seven-character corner is generally a whole board, it needs to be replaced in its entirety once damaged. Therefore, there is an urgent need for a seven-character corner that is stronger and less likely to be damaged.

[0003] Patent Document 1 (Publication No. CN203755521U) discloses a suspended ceiling frame, which includes a base frame profile and a decorative piece profile. The base frame profile is provided with a surrounding structure, and the decorative piece profile is fixedly installed in the surrounding structure by a hook and a toothed claw hook. The two ends of the base frame profile and the decorative piece profile are cut into 45° angles and spliced into a rectangular frame, and the four corners of the rectangular frame are fixedly connected by corner codes. The suspended ceiling frame uses a surrounding claw hook structure for firm connection, which aims to prevent the profile from falling off. However, this structure cannot improve the strength of the profile and cannot prevent the profile from being damaged.

[0004] Patent Document 2 (Publication No. CN206903034U) discloses a positioning and supporting suspended ceiling structure, which includes a main ridge horizontally arranged between walls, and a hanging rod connected to the roof and arranged vertically. The hanging rod is connected to the main ridge, and the end of the main ridge is lapped onto a corner code installed on the corresponding wall. An installation seat is installed on the end of the main ridge. A back plate vertically arranged on the installation seat has a eternit plate installed on one side. A supporting seat is installed on the wall. A sub-ridge is horizontally installed below the end of the main ridge, one end of the sub-ridge is connected to the eternit plate, and the other end is inserted into a connecting slot provided in the supporting seat. The eternit plate and the sub-ridge form a frame at both ends of the main ridge, and a gypsum board is attached to the outside of the frame. The purpose of this suspended ceiling structure is to ensure that the overall suspended ceiling structure has sufficient supporting strength, and to improve the space inside the suspended ceiling, making it easy to arrange pipelines inside the suspended ceiling. However, this structure cannot improve the strength of the gypsum board and cannot prevent the gypsum board from being damaged. SUMMARY
