Description

Technical Field

[0001] The invention relates to the technical field of building installation equipment, in particular to a bolt device installed on an arc structure. Background Art

[0002] In construction, tension bolts are often used to penetrate two plates to fix the two plates. When fixing curved surface structures, tension bolts are often used directly to fix them. However, in actual use, when using existing tension bolts to fix curved surface structures, the following problems exist: (1) The hexagonal head and nut of the tension bolt cannot be completely pressed against the surface of the curved surface structure, causing the local surface pressure of the contact part of the curved surface structure to be too large, which is prone to deformation; (2) The total length of the tension bolt cannot be dynamically adjusted according to the required tension spacing length, so that the total length of the tension bolt is generally much larger than the required tension spacing length, resulting in the end of the tension bolt protruding too much from the surface of the curved surface structure, which is easy to collide with other objects during use; (3) The existing tension bolt cannot be used on curved surface structures where the center axes of the two screw holes are not on the same straight line.
