Problems solved by technology

[0002] At present, the installation method of the sliding bearing device of civil building stairs is realized by pouring concrete after directly laying two plastic sliding sheets on the steel bars of the raft, the rest platform of the stairs, and the floor ladder beam. The disadvantages of this device are: The plastic sliding sheet will directly press on the steel bar of the floor ladder beam after bearing the concrete, which will easily cause the deformation of the two plastic sliding sheets when pouring concrete, and cannot achieve the sliding effect of the sliding support device of the stairs, which will easily cause structural safety hazards

Embodiment 1

[0024] Please refer to figure 1 As shown, a sliding bearing device for stairs includes a floor beam and a stair tread, and also includes a support plate 1 and a support plate 2 2, and a connecting piece 3 is fixedly installed on the supporting plate 1, and the connecting piece 3 is welded and fixed with the steel bars of the floor ladder beams and kept in a horizontal state, and the support plate 2 is fixedly installed with the steel bars of the stair treads, and the support plate 1 and the support plate 2 2 are provided with a support for dragging the stair treads Sliding mechanism, said sliding mechanism comprises oil paper one 4, sliding sheet one 6, oil paper two 5 and sliding sheet two 7 which are laid out in order from bottom to top, and sliding sheet two 7 is embedded in the concrete interior of the stair tread.

Embodiment 2

[0026] Please refer to figure 2 As shown, a further preferred solution based on Example 1, the support plate 1 is provided with a limiting groove 1 8 for installing the sliding piece 6, and the support plate 2 2 is provided with a sliding piece 2 7 for installation. The limit groove two 9. Utilize limit groove one 8 and limit groove two 9 can carry out position limitation of slide piece one 6 and slide piece two 7 respectively, can prevent slide piece one when relative sliding (slide piece one 6 and slide piece two 7) 6 slides relative to support plate one 1, sliding piece two 7 and support plate two 2.

[0027] In a further preferred solution in this embodiment, the first sliding sheet 6 and the second sliding sheet 7 are both plastic sheets, and the use of plastic sheets can greatly save construction costs.

Embodiment 3

[0029] Please refer to figure 2 As shown, a construction method of a stair sliding bearing device includes the following steps: firstly drill holes at the four corners of the support plate 1, secondly connect the connecting piece 3 with screws inside each hole, and then connect the end of the connecting piece 3 The upper part is welded on the steel bar of the floor ladder beam, and ensure that the support plate 1 is in a horizontal state, the support plate 2 and the steel bar of the stair step plate are fixed and installed, and the oil paper 4 and the sliding piece 1 are laid on the inside of the limit groove 8 again. 6. Oil paper 2 5, sliding piece 7, ensure that the sliding piece 2 7 is installed in the limit groove 2 9 on the support plate 2 2, and finally pour the concrete for the floor ladder beam, and then pour the stairwell shear wall and the stair step slab of concrete.

Abstract

The invention discloses a stair sliding support device and a construction method, and belongs to the technical field of building construction. The stair sliding support device comprises a floor stair beam, a stair plate, a first supporting plate and a second supporting plate, a connecting piece is fixedly installed on the first supporting plate, the connecting piece and a reinforcing steel bar of the floor stair beam are welded and fixed and are kept in a horizontal state, the second supporting plate and a reinforcing steel bar of the stair plate are fixedly installed, and a sliding mechanism for bearing and dragging the stair plate is arranged between the first supporting plate and the second supporting plate. The first supporting plate is fixed with the reinforcing steel bar of the floor stair beam through the connecting piece and is kept in a horizontal state, the second supporting plate is fixedly installed with the reinforcing steel bar of the stair plate, the sliding mechanism is arranged between the first supporting plate and the second supporting plate, and distance sliding is achieved through the sliding mechanism; and the sliding effect can be well guaranteed through the structure, and the deformation condition of the sliding piece during concrete pouring is avoided, so that the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a stair sliding support device and a construction method. Background technique [0002] At present, the installation method of the sliding bearing device for civil building stairs is realized by pouring concrete after directly laying two plastic sliding sheets on the steel bars of the raft, the stair rest platform, and the floor ladder beam. The disadvantages of this device are: The plastic sliding sheet will directly press on the steel bar of the floor ladder beam after bearing the concrete, which will easily cause the deformation of the two plastic sliding sheets when pouring concrete, and cannot achieve the sliding effect of the sliding support device of the stairs, which will easily cause structural safety hazards. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art, so a kind of stair sliding s...
