the anti-lifting buckle beam is vertical to the fixed cross beam, so that the anti-lifting buckle beam and the fixed cross beam both have long enough sliding matching ends, the requirement of sliding distance is reliably met, and the reliability of applying anti-lifting constraint on the anti-lifting buckle beam by the fixed cross beam is also ensured;
by adopting a steel structure, on the premise of providing the same constraint capacity, the cross-sectional dimension and the occupied space of the component can be reduced to the maximum extent, so that the requirement of the whole degree reducing device on the installation space is met;
by adopting the steel pipe concrete structure, on the premise of providing the same constraint capacity, the using amount of steel can be greatly reduced, so that the manufacturing cost of the device is greatly reduced, and the abrasion caused by sliding friction can be reliably reduced, so that the service life and the reliability of the anti-pulling device are greatly improved;

The arrangement of the idle stroke preventing pre-pressing elastic layer 5 is generally the construction from bottom to top in the construction of a building structure, along with the increase of the weight of the building structure above, the shock insulation rubber support 12 at the shock insulation layer is gradually compressed, so that the gap between the fixed cross beam 2 and the anti-lifting buckle beam 1 is gradually increased, and because of the existence of the gap, when the building structure is subjected to the action of overturning moment, the fixed cross beam 2 and the anti-lifting buckle beam 1 are impacted, the instant impact of the hard impact is extremely large, the fixed cross beam 2 and the anti-lifting buckle beam 1 are extremely easy to damage, so that the anti-pulling device fails, or the service life is greatly shortened, therefore, in the application, the idle stroke preventing pre-pressing elastic layer 5 is made of elastic materials, when the shock insulation layer structure is constructed, the idle stroke preventing pre-pressing elastic layer 5 is firstly in a compressed state, and along with the increase of the construction of the building structure, although the shock insulation rubber support 12 is still compressed to cause the increase of the gap between the fixed cross beam 2 and the anti-lifting buckle beam 1, the anti-idle-stroke prepressing elastic layer 5 is gradually recovered to enable the low friction layers on the fixed cross beam 2 and the anti-lifting buckle beam 1 to be always contacted, and after the construction of the building above is finished, the low friction layers of the fixed cross beam 2 and the anti-lifting buckle beam 1 are in a contact state or in a small clearance fit state or in a slight extrusion state, so that the damage caused by hard collision between the fixed cross beam 2 and the anti-lifting buckle beam 1 due to the gap is avoided or reduced, the structural safety is greatly improved, the service life is greatly prolonged, and the noise caused by impact is also greatly reduced; and prevent that idle stroke pre-compaction elastic layer 5 can also play good buffering effect, when preventing carrying to draw buckle roof beam 1 and being carried by the building structure of top and draw and form the impact to fixed cross beam 2, prevent that idle stroke pre-compaction elastic layer 5 provides the buffering, reduces and resists to carry the risk of drawing the device because of assaulting the too big damage.

Thus, elimination of backlash is further ensured.
