Description

Technical Field

[0001] The utility model relates to the technical field of stair sliding support structures, in particular to a stair sliding support. Background Art

[0002] Traditional sliding bearings are made by gluing polytetrafluoroethylene pads to the concrete surface. Each staircase needs to be divided according to the sliding bearing platform. The next step can only be constructed after the previous platform is cast and the pad is glued. In factory projects, the floor height is high and the first floor staircase will be in the form of three runs. Considering the setting time of concrete, the staircase construction is cumbersome and will seriously lag behind the overall construction progress.

[0003] In addition, most construction parties believe that pads are of little significance in practical applications, the construction is complicated, and the safety officer cannot detect whether the pads were used during the construction process after the construction is completed. Therefore, in order to reduce working hours, they choose not to install pads and directly carry out construction, which poses a huge safety hazard. Utility Model Content

[0009] A stair section formwork is placed on the upper end surface of the first pad after the sliding support pad, the pad lower section formwork and the supporting steel bars are cast and constructed. A concrete layer is also cast between the stair section formwork and the sliding support pad.

[0010] As a further improvement, the width of the sliding support pad is the same as the step width, and the length is the same as the ladder board width, and the sliding support pad is a 5mm thick polytetrafluoroethylene plate.

[0011] As a further improvement, at least one row of three overflow holes are provided on the sliding support pad, and at least two pairs of mutually symmetrical fixing holes are provided on the contour edge of each overflow hole.

[0012] As a further improvement, the distance between two fixing holes is not less than 100 mm, and the closest distance between each fixing hole and the adjacent side thereof is not more than 50 mm.

[0017] The beneficial effects of the utility model are:

[0018] Traditional sliding bearings require pouring concrete first, and then laying polytetrafluoroethylene plates after the bottom concrete solidifies. After it is stabilized, the next step is constructed and then poured, which prolongs the construction period. The utility model embeds supporting steel bars in the upper staircase floor deck of the upper staircase, and the supporting steel bars support the lower section template of the pad and the sliding bearing pad. The sliding bearing pad is provided with overflow holes, and pads are provided on the upper end surface of the sliding bearing pad. The staircase template is finally set at the upper end of the location fast, so that the pouring process in the construction steps of the sliding bearing can be continuous, and there is no need to wait for the bottom concrete to solidify before laying the polytetrafluoroethylene plate to form a partition and then placing the step steel bars and pouring. During the pouring process, the setting time of the upper and lower concrete layers of the sliding bearing pad can be guaranteed to be consistent, and the construction period can be greatly shortened.
