Description
Technical Field
The invention relates to a connecting method of a stair and a support and a polytetrafluoroethylene plate stair sliding support, and belongs to the field of concrete structures.
Background
The traditional cast-in-place stair adopts rigid connection, and the rigidity is increased, and the stair is damaged greatly due to the large rigidity during the earthquake, so that huge damage to a house is caused.
Disclosure of Invention
The invention aims to provide a connecting method of a stair and a support and a polytetrafluoroethylene plate stair sliding support, so that a stair support platform only bears pressure and does not transmit bending moment, a platform plate and the stair can freely deform and translate, seismic force is consumed, damage caused by an earthquake is reduced, and the defects of the prior art are overcome.
In order to achieve the purpose, the invention provides the following technical scheme:
a method for connecting stairs with support features that a sliding support is arranged between the stair boards and support, and the "putting" principle of anti-seismic fortification is used to disconnect the stair board structure from the lower support structure, so the platform only bears pressure but does not transfer bending moment, resulting in free deformation and translation of floor slab and stairs.
Preferably, set up sliding support and mean that stair step board and support platform, surface course all break off, can not form rigid connection promptly, set up the polytetrafluoroethylene board between stair step board and support platform and realize that support platform supports the stair step board, be located and form the expansion joint between surface course and the stair step board of support platform upper end, set up the polyphenyl board between the expansion joint and realize platform floor and stair free deformation and translation.
The utility model provides a polytetrafluoroethylene board stair sliding support, includes the terraced roof beam, and the both wings board of this terraced roof beam is layer board and terrace plate respectively, and the surface course setting sets up the terraced board in the terrace plate top on the layer board, and sets up the polytetrafluoroethylene board between layer board and terraced board, form the expansion joint between terraced board and the surface course, set up the polyphenyl board between the expansion joint.
Preferably, the supporting plate is suspended on the ladder beam, and the width of the supporting plate is equal to that of the step on the ladder board.
Preferably, the width of the polytetrafluoroethylene plate is equal to that of the step on the step plate, the polytetrafluoroethylene plate is bonded on the supporting plate, and the step plate is placed on the polytetrafluoroethylene plate.
Preferably the polystyrene board has a height equal to the thickness of the top layer.
Compared with the prior art, the stair support platform can only bear pressure, does not transmit bending moment, can freely deform and translate the platform plate and the stair, consumes earthquake force, and reduces damage caused by earthquake.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
The labels in the figures are: 1-ladder beam, 2-supporting plate, 3-platform plate, 4-surface layer, 5-ladder plate, 6-polyphenyl plate, 7-polytetrafluoroethylene plate and 8-step.
Detailed Description
The support structure in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a method for connecting stairs with support features that a sliding support is arranged between the stair boards and support, and the "putting" principle of anti-seismic fortification is used to disconnect the stair board structure from the lower support structure, so the platform only bears pressure but does not transfer bending moment, resulting in free deformation and translation of floor slab and stairs.
Wherein set up sliding support and mean stair board and support platform, surface course all break off, can not form rigid connection promptly, set up the polytetrafluoroethylene board between stair board and support platform and realize support platform to the support of stair board, be located and form the expansion joint between surface course and the stair board of support platform upper end, set up the polyphenyl board between the expansion joint and realize platform floor and stair free deformation and translation.
The polytetrafluoroethylene plate stair sliding support comprises a ladder beam 1, wherein two wing plates of the ladder beam 1 are a supporting plate 2 and a flat plate 3 respectively, a surface layer 4 is arranged above the flat plate 3, a ladder plate 5 is arranged on the supporting plate 2, a polytetrafluoroethylene plate 7 is arranged between the supporting plate 2 and the ladder plate 5, an expansion joint is formed between the ladder plate 5 and the surface layer 4, and a polystyrene plate 6 is arranged between the expansion joints.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms while ensuring the essential characteristics of the invention. All changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
