Description

Technical Field

[0001] The utility model belongs to the technical field of grid structures, and in particular relates to a grid structure arch connecting piece. Background Art

[0002] The spatial structure formed by multiple rods connected by nodes in a certain grid form is used in the construction of building vaults because of its advantages such as small spatial force, light weight, high rigidity and good seismic performance.

[0003] At present, in the existing grid structure, the connection between some connecting rods is often achieved by welding. This connection method causes the grid structure to be inconvenient to transport due to its large transportation volume, and it is also unable to adapt to arch structures of different shapes.

[0004] Therefore, in order to address the problems that most of the existing grid structures use welding to connect the connecting rods, which makes the transportation volume large and inconvenient and cannot be adjusted according to the different shapes of arch structures, a grid structure arch connecting piece is designed. The connecting piece is used to connect the connecting rods to each other, which is convenient for transportation and can be improved according to the size of the arch. Utility Model Content

[0007] Preferably, a grid structure arch connecting part is designed to replace the traditional welded grid, so as to reduce the transportation volume of the grid structure during transportation and improve the transportation efficiency. The connecting components can be rotated, and the grid structure is assembled and can be adjusted according to the arch structure to improve the versatility.

[0008] Preferably, the connecting assembly includes a No. 1 connecting rod and a No. 1 connecting column; one end of the truss column is connected to the No. 1 connecting rod, and the No. 1 connecting rod is movably connected to the No. 1 connecting column, and the truss column is connected to the No. 1 connecting piece or the No. 2 connecting piece through the connecting assembly.

[0009] Preferably, a rotating shaft is fixedly connected to the outer side of connecting column No. 1, and a rotating plate movably sleeved on the outer side of the rotating shaft is fixedly connected to the bottom end of connecting rod No. 1. The rotating plate sleeved on the outer side of the rotating shaft can drive connecting rod No. 1 to rotate on connecting column No. 1, thereby facilitating adjustment of the angle of the grid column connected thereto.

[0010] Preferably, both ends of the grid column are fixedly connected with a No. 2 connecting column with a surface fixed connection thread structure, and the No. 2 connecting column is screwed into the inner side of the No. 1 connecting rod. The grid column is connected to the connecting assembly by screwing the No. 2 connecting column into the No. 1 connecting rod.

[0011] Preferably, a threaded structure is fixedly connected to the outer side of the No. 1 connecting column, and a No. 2 connecting rod matching the No. 1 connecting column is fixedly connected to the three side surfaces of the square No. 1 connecting piece. The three surfaces of the square No. 1 connecting piece for connecting the No. 2 connecting rod are all flat, and the remaining flat surface can be installed on the foundation to form an edge without cutting.

[0012] Preferably, the hexagonal columnar No. 2 connecting piece is fixedly connected to six No. 3 connecting rods arranged in a ring, and the No. 1 connecting column is screwed to the inner side of the No. 3 connecting rod. The hexagonal columnar No. 2 connecting piece has multiple side faces and can be used to install multiple grid columns and combine them into a relatively stable triangular structure.

[0013] Preferably, the No. 1 connecting piece and the No. 1 connecting piece are bonded with a building roof panel cut into a suitable shape, the No. 2 connecting piece and the No. 2 connecting piece are bonded with a building roof panel, and the No. 1 connecting piece and the No. 2 connecting piece are bonded with a building roof panel. Since there is a plane between the No. 1 connecting piece and the No. 2 connecting piece, the building roof panel can be easily installed.

[0014] Beneficial effects of the utility model:

[0015] By designing a grid structure vault connection piece, the grid columns are connected by connecting pieces No. 1 and No. 2, replacing the traditional welding method. This connection method facilitates the decentralized transportation of the grid structure. This transportation method enables more parts to be transported in one transportation than in the past, thus improving transportation efficiency.

[0016] The No. 1 connecting rod and the No. 1 connecting column are connected by a rotating shaft. By rotating the No. 1 connecting rod, the angle between the No. 1 connecting rod and the grid column screwed into the No. 1 connecting rod can be changed, so that the angle of the grid column can be adjusted according to the vault structure, thereby improving the versatility of the grid structure.

[0017] The connecting parts are divided into No. 1 connecting parts and No. 2 connecting parts. Since No. 1 connecting parts have more flat surfaces, they are used to form the edge positions of the truss structure. There are more No. 3 connecting rods connected to No. 2 connecting parts, which can connect multiple truss columns. BRIEF DESCRIPTION OF THE DRAWINGS
