Articulated diagonal strut member joining method

The invention relates to a method for joining an articulated diagonal strut member; in particular, to a method for articulating a diagonal strut member of a general building structure with a building.

As shown in Figure 1, the M453702 pin-type frustration beam support device, the pin holes at both ends need to be completed in the factory. If you want to work with the site hole spacing at the site assembly stage, there will be dimensional accuracy. The problem is that it is difficult to match the on-site processing machinery at the construction site. However, after the production of the pin holes at both ends is completed in the factory, it is necessary to match the distance between the two holes on the structural members of the site. When it is large, it is easy to cause the pin-connecting hole at the end of the pin-type frustration support to be difficult to align with the fixing hole. The pin will not be able to be inserted into the pin-receiving hole smoothly, and the grinding and reaming needs to be processed on site, but this also makes the round hole and The gap between the bolts is too large, and it is impossible to stabilize the tension and pressure of the axial reversal without shaking, so that the energy dissipation effect is compromised. Therefore, the M453702 pin-connected frustum beam support device requires high precision control on site assembly and construction. It is difficult and time-consuming to construct.

The method for joining the hinged diagonal strut members of the present invention is to connect the shaft hole plate and the connecting plate on the structure into the shaft hole by means of the shaft rod, so that the shaft hole plate and the connecting plate have the function of relative rotation, and then The temporary fixing device temporarily fixes the shaft hole plate and the connecting plate and cannot rotate relative to each other, and then connects the end portion of the diagonal strut member and the shaft hole plate in an interlaced manner and is welded and fixed, and finally releases the temporary fixing device to make the shaft hole plate and the connection. The plate recovery function can be relatively rotated, so that the diagonal strut member and the structure can be hingedly connected.

The method for joining the hinged diagonal strut members of the present invention is characterized in that the shaft hole plate and the connecting plate are temporarily fixed by the temporary fixing device into a connection type of the conventional diagonal strut member, and the end portion of the diagonal strut member and the shaft hole plate are obtained. When interlaced, the length allows a large error, and the relative error can be equally distributed to both ends by adjusting the relative position. It is not only easy to install, but also meets the quality of the installation, overcoming the conventional hinge When assembling the strut, it is very difficult to precisely align the hole position.
