[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1 and 2As shown, a beam-type staircase sliding support comprises an upper pier 3 mounted on a beam 2 of a lower platform 1 (the lower platform is a floor). The left side of the upper pier 3 is flush with the left side of the beam 2, and the right side protrudes beyond the right side of the beam 2 (the beam 2 is 400 mm wide in the left-right direction). The upper pier 3 is constructed of reinforced concrete, with a height of 300 mm, a length of 1550 mm in the front-to-back direction, and a width of 500 mm in the left-to-right direction. A pad 4 is provided on the top surface of the upper pier 3. The pad 4 has the same shape and size as the top surface of the upper pier 3. The pad 4 is a 5 mm thick polytetrafluoroethylene sheet with high strength, good wear resistance, and a low coefficient of friction. The polytetrafluoroethylene sheet is secured to the top surface of the upper pier 3 with flat-head bolts. The stair section 5 of the beam-type staircase is arranged in a left-to-right direction, with the left end being the lower end. The lower end of the stair section 5 slides on the polytetrafluoroethylene sheet and is positioned to the left, while the upper end is mounted on the upper platform using conventional techniques. A connecting stair section 6 is provided on the lower platform 1. The connecting stair section 6 is a brick structure or a reinforced concrete structure. The connecting stair section 6 is connected to the stair section 5 of the beam type staircase. The connecting stair section 6 is aligned with the stair section 5 of the beam type staircase in the width direction. The steps and steps of the connecting stair section 6 are consistent with the steps and steps of the stair section 5 of the beam type staircase. The lower end of the right side of the connecting stair section 6 is affixed to the turning pier 3, and there is a 50mm wide gap between the upper end and the stair section 5 of the beam type staircase. The gap is filled with a buffer body 7, which is a polystyrene board.

[0023] In this embodiment, an upper pier 3 is utilized, and a pad 4 is laid on the top surface of the upper pier 3, so that the lower end of the stair section 5 of the beam-type staircase slides onto the pad 4, thereby achieving the arrangement of the lower end of the stair section 5 of the beam-type staircase at the upper pier 3. When the stair section 5 of the beam-type staircase deforms during an earthquake, the stair section 5 of the beam-type staircase slides on the pad 4, leaving room for deformation. The connecting staircase 6 not only connects the stair section 5 of the beam-type staircase with the lower platform 1, but also limits the sliding range of the lower end of the stair section 5 of the beam-type staircase. The provision of a buffer between the connecting staircase 6 and the lower end of the stair section 5 of the beam-type staircase can prevent the stair section 5 of the beam-type staircase from being damaged by hard contact with the connecting staircase 6 when it deforms.

[0024] Example 2

[0025] like Figure 3 As shown, the difference from Example 1 is that: there is a stair lateral limit upper pier 8 on the upper pier 3 corresponding to the air-facing side (i.e., the front side) of the stair section 5 of the beam-type staircase, and the height of the stair lateral limit upper pier 5 is 300 mm, the thickness in the front-to-back direction is 200 mm, and the left-right direction is aligned with the upper pier 3. There is a 50 mm wide gap between the stair lateral limit upper pier 8 and the stair section 5 of the beam-type staircase, and the gap is filled with a buffer body 7, which is a polystyrene board.

[0026] In this embodiment, the stair lateral limit upper pier 8 is set to limit the lateral sliding range of the stair section 5 of the beam type staircase, and the buffer body 7 is set between the lower end of the stair section 5 of the beam type staircase and the stair lateral limit upper pier 8 to prevent the stair section 5 of the beam type staircase from being damaged by hard collision with the stair lateral limit upper pier 8.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
