Principle of operation

When in use, the upper diagonal draw bar 2, the lower diagonal draw bar 3 and the adjustable turn buckle assembly 4 are assembled; no matter the stress monitoring mechanism 5 is assembled on the upper inclined pull rod 2 or the lower inclined pull rod 3 in advance. The total length of the device is matched with the actual length; then, connecting the upper end of the upper diagonal member 2 with the building outer wall 100; then connecting the lower end of the lower diagonal draw bar 3 with the cantilever beam end of the cantilever beam 1, wherein the adjustable turn buckle assembly 4 may need to be adjusted in the process so as to adapt to the structural size; and then screwing up the adjustable turn buckle assembly 4 according to construction requirements, and moving the upper inclined pull rod 2 and the lower inclined pull rod 3 inwards in opposite directions for tensioning so as to enable the whole structure to be in a working bearing state. This process is common knowledge of construction and will not be described in detail.

At this time, since the adjustable turn buckle assembly 4 tensions the upper diagonal member 2 and the lower diagonal member 3 to pull the upper connecting rod segment 231 (or the lower connecting rod segment 232), the supporting compression spring 8 is compressed, the contact surface of the sliding stopper 9 and the supporting compression spring 8 contacts the second stopper 27, and the connecting cylinder 7 is under tension, as shown in the state of fig. 8, the system is in rigid connection. At this time, the marking screw 10 is also moved to the side of the long axial marking hole 14 close to the supporting compression spring 8, close to the end arc surface 25, where it cannot be forced, avoiding interference with the force between the slide stopper 9 and the second stopper 27. At this time, one end of the supporting compression spring 8 is in contact with the sliding stopper 9, and the other end is in contact with the first stop 26, so that the supporting compression spring 8 is in a compressed state and keeps the extending movement trend.

As shown in fig. 12, if the adjustable lag bolt assembly 4 becomes loose, the upper diagonal member 2 and the lower diagonal member 3 move in opposite directions, the upper diagonal member 2 and the lower diagonal member 3 are released, and the supporting compression spring 8 is in a compressed state, so as to maintain the extending movement tendency, the supporting compression spring 8 will support the sliding stopper 9 to slide along the slideway hole 73 toward the end stud member 12 side, and pull the upper connecting rod section 231 (or the lower connecting rod section 232), so that the upper diagonal member 2 and the lower diagonal member 3 handle a "false tensioning" state, although the loosening cannot be seen, the system safety is reduced because only the supporting compression spring 8 is stressed. At this time, the position change of the sliding block 9 can be observed from the axial sign long hole 14, thereby reminding workers that the system is unsafe and needs to be evacuated and treated as soon as possible. When the relative position change is found to be larger than a certain value, such as 5mm, the adjustable flower basket component 4 needs to be readjusted to meet the construction stress requirement. Of course, if the screw 10 is provided, the change in position of the slide stopper 9 can be observed more intuitively.

In summary, the tension rod stress monitoring device for the tension rod type turn buckle cantilever frame provided by the embodiment of the invention is used for high-rise and super high-rise building construction, the cantilever beam is fixedly connected to the main structure, the cantilever beam is used as a stress rod piece of the upper outer frame body to bear all loads of the outer frame body, and the oblique tension member turn buckle rod is used for achieving double safety guarantee on the frame body, so that the problems that the cantilever beam frame is not firmly connected with the main structure and the stress of the cantilever beam frame body is unreasonable are solved, the bearing capacity of the cantilever beam frame can be improved, the stability of the cantilever beam frame is improved, the safety of the frame body is guaranteed, and the frame body is simple in structure and convenient to install.
