Wherein the support bracket 120 automatically rotates out of the housing 110 by its own weight and extends into the hole 201 and is maintained in a vertical orientation when the sliding displacement apparatus 100 is placed on the foundation 200. The operator is not required to rotate the support bracket 120. After the support bracket 120 rotates to the vertical direction, the support bracket 120 can be stably kept in the vertical direction through a limiting mechanism. Referring to fig. 24, when the horizontal jack 150 pushes, the support bracket 120 of the sliding displacement device 100 is pressed against the left side wall of the hole 201 by the reverse force of the horizontal jack 150, so that the existing building and the wall 302 are translated to the right.

That is, the recovery process of the support bracket 120 of the sliding displacement apparatus 100 of the present invention is also automated, and the operator is not required to rotate the support bracket. Therefore, the support bracket 120 according to the embodiment of the present invention realizes an automatic operation in the horizontal state and the vertical state rotation processes.

The sliding displacement method for the existing building provided by the embodiment of the invention further comprises the following steps before the existing building is displaced in parallel:

Step one, please refer to fig. 1 to 3, excavating a wall 302 of an existing building until a foundation 301 of the existing building is exposed, and pouring concrete on the foundation 301 of the existing building, so that the foundation 301 of the existing building and the poured concrete form a lower tray beam 401, where the lower tray beam 401 is the foundation 200. The method also comprises the step of reinforcing the existing building before the wall 302 of the existing building is excavated.

The opening can be constructed by adopting a skip method. After the connecting beam 402 and the wall clamping beam 403 are constructed, maintenance is required to meet the strength requirement.

Referring to fig. 4, a steel support column 404 is disposed between the wall-clamping beam 403 and the lower tray beam 401. The upper ends of the steel support columns 404 and the lower embedded parts of the wall clamping beams 403 can be welded or connected through fasteners, and the steel support columns 404 and the embedded parts of the lower tray beams 401 can be welded or connected through fasteners.

The sliding component 407 in the fifth step has three modes.

The first method is as follows: referring to fig. 29, the skid assembly 407 includes a track beam 407a, a mortar layer 407b and a skid steel plate 407c sequentially arranged.

The second method comprises the following steps: glide assembly 407 includes track beam 407a and glide steel plate 407 c.

Mode three, glide assembly 407 includes only glide steel plate 407 c.

The mortar layer 407b is used for leveling the uneven surface of the track beam 407a, the thickness of the mortar layer may be not less than 20mm, and the surface is roughened and cured to the design requirement. The contact surface between the slipping steel plate 407c and the mortar layer 407b is roughened, for example, the friction coefficient between the mortar layer 407b and the slipping steel plate 407c is greater than 0.2, so as to ensure that the friction coefficient during normal translation of the dynamic friction between the mortar layer 407b and the slipping steel plate 407c is 0.04 and the friction coefficient at start-up is 0.1.

The risk of damaging the upper wall 302 due to the rigid connection of the slider 406b to the upper pallet beam 405 when the slider 406b is directly used is avoided. When the heights of the sliding feet 406 of the upper tray beam 405 and the lower tray beam 401 are not enough, the heights of the sliding feet 406 can be adjusted through the backing plates. For example: the runner 406 may be modular to 30mm, 60mm, 90mm, etc. When the runner 406 includes the vertical jack 406a, after the runner 406 is installed, the stability of the vertical jack 406a is checked and the test is performed.
