Connecting bolt enabling screw to be mounted afterwards and using method of connecting bolt

Abstract

The invention discloses a connecting bolt enabling a screw to be mounted afterwards and a using method of the connecting bolt. The connection bolt comprises a screw and a rectangular bar. One end of the screw is provided with threads, and the other end is provided with a through notch. The through notch extends to the screw end portion along the direction of an axis of the screw, the rectangular bar is in pin connection onto the screw through a pin shaft in the through notch, and an axis of the pin shaft is vertical to the axis of the screw. The rectangular bar and the geometric center of the pin shaft do not coincide, all or part of the rectangular bar can be placed in the through notch, and the rectangular bar can swing to a position parallel with the axis of the screw or vertical to the axis of the screw around the pin shaft. According to the connecting bolt enabling the screw to be mounted afterwards and the using method of the connecting bolt, the screw is inserted into a bolt hole after two templates are mounted in position and bolt holes are aligned, so that template edges can be fastened; and the screw can be mounted afterwards, so that the fastening mode can be simplified, and the construction progress is fastened.

Description

technical field [0001] The invention relates to a connecting bolt capable of post-mounting screw rods and a method for using the connecting bolt capable of post-mounting screw rods, especially suitable for occasions where two or more layers of components need to be fixed by bolts but there is no operating space inside. Background technique [0002] Conventional bolts all are to first thread the screw rod into the bolt hole, and after installing the object to be fastened, tighten the nut outside to realize fastening. In some cases, the object to be fastened includes multiple layers, the deformation performance of the object is not high, large deformation is not allowed, and there is no operating space on the opposite side. At this time, it is difficult to fasten the object with conventional bolts. [0003] If demolition-free formwork is used to reinforce structures such as pier columns, the formwork often adopts lap joints instead of the flange plate butt joint form commonly ...

Problems solved by technology

In some cases, the object to be fastened includes multiple layers, the deformation performance of the object is not high, large deformation is not allowed, and the opposite side has no operating space, at this time it is difficult to fasten the object with conventional bolts

[0003] If demolition-free formwork is used to reinforce structures such as pier columns, the formwork often adopts lap joints instead of the flange plate butt joint form commonly used in steel formwork, and the inside of the formwork does not have operating conditions. At this time, conventional bolts cannot be used. its fastening
