BACKGROUND

A spatial grid structure has become a promising spatial structure owing to its reasonable stress, economical materials, beautiful and diverse shapes and covering a large space. Joints are key components of the spatial grid structure. A bolted spherical joint is widely used in the spatial grid structure because of its advantages of convenient and fast field installation, short construction period, and high installation efficiency.

However, due to lower redundancy of the spatial grid structure, the failure of the joint is likely to lead to continuous collapse of a corresponding whole structure. In the earthquake, the failure of the joint is mainly caused by low-cycle fatigue cumulative damage, and seismic performance of the whole structure is also closely related to energy dissipation capacity of the joint. In addition, due to the influence of machining accuracy, an existing bolted spherical joint member is not coaxial with a bolt ball, which leads to the difficulty of on-site installation, and the forced installation thereof is easy to cause an internal stress in the structure, which makes an actual working condition of the structure inconsistent with the design.

The threaded cap 4 is screwed onto the rod body 22.

For the direction-adjustable bolted spherical joint for collapse resistance and earthquake resistance disclosed in the disclosure, when the direction-adjustable bolted spherical joint for collapse resistance and earthquake resistance is used, the connecting rod 2 is inserted into the threaded barrel 3, the connecting rod 2 inserted into the threaded barrel 3 is connected into the bolt ball 1, and the threaded cap 4 is screwed onto the connecting rod 2 to make the threaded cap 4 abut against the end of the threaded barrel 3. As such, the threaded barrel 3 realizes tensile capacity between the connecting rod 2 and the bolt ball 1; the threaded cap 4 realizes compression resistance of the connecting rod 2, increases locking strength of the direction-adjustable bolted spherical joint, and realizes the collapse resistance and earthquake resistance of the bolt ball 1; and the ball head 21 at the end of the connecting rod 2 abutting against the threaded barrel 3 prevents the connecting rod 2 from being pulled out, thereby realizing the tensile function.

In an illustrated embodiment, the threaded barrel 3 includes a barrel body 31, which is disposed in the connecting hole 11 and is crewed into the bolt ball 1. The ball head 21 is disposed to abut against an end of the barrel body 31 disposed in the bolt ball 1, i.e., an end of the barrel body 31 facing away from the threaded cap 4.

In order to achieve direction adjustable, a bearing surface of the threaded barrel 3 abutting against the end of the connecting rod 2 and is spherical, and an inner wall of the threaded barrel 3 is conical, so that the connecting rod 2 can rotate around the end in all directions and absorb energy.

In an illustrated embodiment, the rod body 22 is fixedly connected to a threaded section 24 disposed on the rod body 22, and the threaded cap 4 is screwed onto the threaded section 24.
