As shown in fig. 1 to 6, a segmental assembly type building translation rail comprises at least two rail units 1 which can be assembled and separated. Two end faces of the rail unit 1 are respectively provided with corresponding shear key grooves 12, and shear keys for bearing shearing force are arranged in the shear key grooves 12 connected with the two spliced rail units 1. In the existing building translation track splicing structure, a structure special for bearing shearing force on a plane vertical to the advancing direction is not provided. Because the absolute parallel and level of the ground can not be guaranteed in the construction process, the joint of the two track units 1 can bear larger shearing force, the damage is easy to occur, the connection is broken, the track is uneven, and the smooth operation of the translation process is influenced. The shear key can be a common rigid structure such as a pin, a shaft and the like, and a plurality of shear keys are arranged side by side. Variable stiffness materials may also be used. Each length of the unit track 1 is L, and one translation track is composed of a plurality of track units 1 and is placed on the concrete cushion 2 to form a complete translation track. The translation building 3 is pushed by a jack to slide on the translation track, and the specific structure can refer to the patent document in the background technology.

The shear key can be a combination pad 14, the combination pad 14 is a flexible sealing material, the combination pad 14 comprises a slurry bag 16 and a communicating pipe 17, and the shape of the slurry bag 16 corresponds to that of the shear key groove 12; a grouting hole 18 is formed at one end of the bonding pad 14, and a grout overflow hole 20 is formed at the other end; the slurry in the bond pad 14 solidifies to form a shear bond. Pressure grouting is required for the conjugate pad 14, the grout being a non-shrinking gel material. After the slurry in the slurry pockets 16 of the bonding pads 14 sets and reaches the required strength, a shear bond is formed that transfers shear forces between the two track units 1. The bonding pad 14 is filled with air before use to check air tightness and keep the inflated state for standby.

The adjacent shear key grooves 12 are connected through a communication groove 13 to form a shear key group; the communication groove 13 has a shape corresponding to the shape of the communication tube 17 of the bonding pad 14. Two shear key groups are symmetrically arranged in the middle of the end face of the track unit 1, and two shear key groups are respectively arranged at the two sides of the end face of the track unit. Of course, the rail unit 1 may be provided in other places as needed and in the cross-sectional shape thereof. The size and walking of the shear key groups at different positions are not necessarily the same.

The track unit 1 is provided with through holes parallel to the length direction of the track unit 1, the through holes are called reserved holes 11, steel strands 24 applied with tensioning prestress are arranged in the reserved holes 11, and the steel strands 24 penetrate through the spliced track unit 1. The length direction of the track unit 1 here refers to the direction of building translation, and is also the length direction of track splicing, and the steel strand 24 can bear the tensile force.

The preformed hole 11 is provided with a positioning hole 10 at the end face of the track unit 1, and a sleeve 23 for allowing a steel strand 24 to pass through is arranged in the connected positioning hole 10 of two adjacent track units 1. The sleeve 23 is also subjected to shear forces.

The end face of each track unit 1 is provided with a positioning hole 10, and a positioning pin 22 is arranged in the connected positioning hole 10 of two adjacent track units 1. The positioning pin 22 and the sleeve 23 are made of rigid materials. In addition, the track unit 1 is provided with a hanging ring 9, so that the track unit is convenient to mount, transport and dismount. The positioning pin 22 and the sleeve 23 can also transmit certain shearing force, and simultaneously, under the combined action of the tensioning prestress of the steel strand 24, the track unit 1 forms an integral stress system.

A translation method of a segment assembly type building translation track is characterized by comprising the following steps: the method comprises the following steps: (1) prefabricating a track unit 1; positioning holes 10 and preformed holes 11 are reserved on two end faces of the track unit 1, and a shear key groove 12 is arranged; prefabricating a bonding pad 14, wherein the bonding pad 14 is made of a flexible sealing material and comprises a slurry bag 16 and a communicating pipe 17, two ends of the bonding pad 14 are respectively provided with a grouting hole 18 and a slurry overflowing hole 20, and the shape of the slurry bag 16 corresponds to that of the shear key groove 12; (2) placing two prefabricated track units 1 on a concrete cushion 2 to be butted, placing positioning pins 22 in positioning holes 10, and placing sleeves 23 in the positioning holes 10 at the positions of reserved holes 11; placing the inflated bonding pad 14 into the shear key groove 12, and tightly bonding the inflated bonding pad with the shear key groove 12; (3) penetrating a steel hinge wire 24 into the preformed hole 11, stretching and anchoring the steel hinge wire 24, opening the grouting hole 18 of the combination pad 14 to deflate, performing pressure grouting on the grout bag 16 from the grouting hole 18 of the combination pad 14 until grout without bubbles emerges from the grout overflow hole 20, sealing the grout overflow hole 20 under the grouting pressure, and then sealing the grouting hole 18; (4) after the slurry in the slurry bag 16 of the bonding pad 14 is solidified and reaches the required strength, a shear bond is formed between the two track units 1; (5) the translation building 3 slides on the track unit 1, and the track unit 1 passing by can be disassembled and reassembled in front of the moving direction of the translation building 3.
