Embodiment approach
[0029] The implementation method of the unilateral tightening device connected by detachable triangular head bolts of the present invention is as follows:
[0030] Firstly, in the factory, drill bolt holes at the design positions of the plates to be connected (2), and drill a groove (5) at a certain distance after rotating the bolt holes 60°. When assembling, pass the bolt heads through the to-be-connected Plate (2) bolt hole, then rotate 60° and move down for a certain distance to enter the groove (5) set by the first connecting plate (201), and finally screw the washer (3) and nut (4) into the triangular head bolt (1), so that the triangular head bolt (1) and the nut (4) are assembled together, and then the nut (4) is finally screwed on one side with a torque wrench.
[0031] When the connecting device needs to be disassembled, first unscrew the washer (3) and the nut (4), then move the triangular head bolt (1) up a certain distance and rotate it by 60°, and then connect it ...

The invention discloses a single-side tightening device for detachable triangular head bolt connection. The device is composed of a triangular head bolt, a to-be-connected plate, a gasket and a nut, bolt holes of two connecting plates of the to-be-connected plate are aligned, then a bolt head of the triangular head bolt sequentially penetrates through the two connecting plates through the bolt holes, and the triangular head bolt is rotated by 60 degrees and then moves downwards by a certain distance to enter a groove formed in the first connecting plate; the gasket and the nut are connected with the triangular head bolt, and the nut is tightened to achieve unilateral tightening of the device. Single-side screwing of the bolt can be achieved through the triangular-head bolt, the triangular-head bolt is easy and convenient to produce and easy to produce in batches, the triangular-head bolt can be used for full-bolt connection between closed-section components, the connection requirement can be met, and construction convenience, economical efficiency, reliability and detachability can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of structural engineering steel structures, and in particular relates to a single-side tightening device for detachable bolt connection of industrial and civil building steel structures. Background technique [0002] At present, prefabricated buildings have been widely used in construction projects. The characteristics of prefabrication and on-site assembly effectively solve the problem of construction dust generated during the construction process. However, the current building demolition method is still dominated by extensive demolition, which has brought more environmental pollution problems to the society. Therefore, the construction industry urgently needs an environmentally friendly and clean on-site construction method. The wide application of prefabricated detachable buildings is the most It is expected to be an option to solve the current problems, and the research on new detachable connection metho...
