Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building decoration engineering, and specifically relates to a suspended ceiling expansion joint structure. BACKGROUND

[0002] The house ceiling is an important part of indoor decoration, and the decoration effect directly affects the decoration effect of the whole building space. The house ceiling decoration is divided into direct type and suspension type, wherein the direct type is directly coated with decorative materials on the floor bottom surface, and is generally used in places with low decoration requirements. The suspension type, also known as suspended ceiling, is a common construction method in current indoor decoration engineering, which allows the indoor to have the functions of heat preservation, heat insulation and sound insulation.

[0003] In the decoration engineering, the suspended ceiling material commonly used is gypsum board, which has the characteristics of light weight and easy construction. At present, in order to facilitate production and installation, a plurality of small gypsum boards are often connected to form a whole large gypsum board, and the plurality of small gypsum boards are fixed by abutting against each other. The gypsum boards that are heated and expanded will be pressed against each other, and deformation stress will be generated in the gypsum board, which can easily damage the structure of the board. The gypsum boards that shrink when cold will separate from each other, which can cause the surface to crack and fall off, and there is a safety hazard. Therefore, the expansion joint must be reserved for the gypsum board used for suspended ceiling to avoid cracking due to thermal expansion and cold contraction.

[0004] After searching, the publication number CN207144278U discloses a suspended ceiling expansion joint structure, which comprises a fixed suspended ceiling and a movable suspended ceiling, and a expansion allowance groove is arranged between the fixed suspended ceiling and the movable suspended ceiling. The fixed suspended ceiling comprises a first hanging rod and a first hanging frame. The first hanging rod is fixedly connected with the ceiling, and the first hanging frame is connected with a first time keel. A gypsum board is fixedly connected with the first time keel through a screw. The movable suspended ceiling comprises a second hanging rod and a second hanging frame. The second hanging rod is fixedly connected with the ceiling, and the second hanging frame is connected with a second time keel. A gypsum board is fixedly connected with the second time keel through a screw. A clamping plate is also fixedly connected with the second time keel through a screw. One end of the clamping plate is fixed on the second time keel, and the other end of the clamping plate is overlapped on the first time keel to completely cover the expansion allowance groove. The cracking of the ceiling is avoided. The ceiling surface can freely expand and contract, the expansion point is left at the inside corner position, the construction is convenient, and the labor and materials are saved. The structure is simple to construct, and the actual use effect is very good. However, the suspended ceiling expansion joint structure has the following defects: although the suspended ceiling expansion joint structure can control the cracks, there is no connection between the adjacent gypsum boards, which leads to poor stability of the gypsum boards. Therefore, it is particularly important to improve the existing expansion joint structure and design a new suspended ceiling expansion joint structure to solve the above technical defects and improve the practicality of the overall expansion joint structure.
