Abstract
The utility model provides an assembly type concrete stairway provided with a sliding support. The assembly type concrete stairway comprises a prefabricated concrete stairway section and the sliding support, wherein the prefabricated concrete stairway section comprises a prefabricated step section, an upper supporting part and a lower supporting part extend along the horizontal direction and are respectively arranged at two ends of the step section, the sliding support is fixed on a building body, an edge of the sliding support is provided with an L-shaped pit, and an end portion of the upper supporting part of the prefabricated concrete stairway section is provided with a protrusion matched with the pit so that the upper supporting part of the prefabricated concrete stairway section is supported on the sliding support. According to the scheme of the assembly type concrete stairway, due to the fact that the sliding support is adopted, on the premise that a requirement for a housing industrialization overall assembly type is met, stress conditions of the assembly type concrete stairway are improved through a change in the connecting method between the assembly type concrete stairway and a main body structure so as to ensure that the functions, including rescue and evacuation, of the assembly type concrete stairway are achieved at the time of an earthquake, and adverse effects on the main body structure are reduced.
Description
Technical field
The utility model relates to technical field of buildings, refers to especially a kind of assembly concrete stair that adopt sliding support.
Background technology
Stair are important building structural elements.Existing concrete staircase mainly adopts the cast in situs formula, comprising: stringertype stairway, slabtype stairway, cantilever are marked time board-like and suspension type, and front two kinds are widely used in building field.
Because the stair bench is irregularly shaped for what tilt, and build that site space is narrow and small, operating difficulties, cause traditional cast in situs formula concrete staircase to have significant limitation.The formula of cast in situs simultaneously concrete staircase can cause rough surface uneven due to Action of Gravity Field, and final products are often very large with the design size deviation.In cast-in-place concrete structure, stair adopt the method for main body reserved steel bar after-pouring usually, thereby cause stair can't utilize at the construction field (site), can not play the effect of construction occasional passage.
The utility model content
The technical problems to be solved in the utility model be to provide a kind of build and use more convenient and the assembly concrete stair of employing sliding support.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of assembly concrete stair that adopt sliding support, comprising: precast concrete stair section, sliding support; Wherein said precast concrete stair section comprises prefabricated step section, and the two ends of described step section are respectively equipped with upper support section that along continuous straight runs extends and lower support section; Described sliding support is fixed on Lou Tishang; The edge of described sliding support is provided with L shaped depression, and the end of the upper support section of described precast concrete stair section is provided with the suitable projection of this depression so that the upper support section of described precast concrete stair section is supported on described sliding support.
Wherein, described sliding support top is provided with the polytetrafluoroethylene (PTFE) backing plate, and described lower support section bottom is provided with along continuous straight runs and is provided with at least two pre-embedded steel slabs, and described pre-embedded steel slab interval arranges; The pre-embedded steel slab of the position of described polytetrafluoroethylene (PTFE) backing plate and the position of described pre-embedded steel slab suitable so that described lower support section can slide with respect to described sliding support.
Wherein, be provided with between lower support section's sidewall of described precast concrete stair section and described sliding support and fill the flexible material isolation strip.
The beneficial effect of technique scheme of the present utility model is as follows:
Such scheme provides the employing sliding support, guaranteeing to satisfy under the prerequisite of the whole assembling requirement of housing industrialization, improve the stress condition of stair self by the connected mode that changes stair and agent structure, guaranteeing it in earthquake time performance rescue, the function of evacuating, and reduce the adverse effect to structure.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A section enlarged drawing in Fig. 1;
Fig. 3 is the right view of Fig. 2.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, a kind of assembly concrete stair that adopt sliding support of embodiment of the present utility model comprise: precast concrete stair section 4, sliding support 5; Wherein said precast concrete stair section 4 comprises prefabricated step section, and the two ends of described step section are respectively equipped with upper support section that along continuous straight runs extends and lower support section; Described sliding support 5 is fixed on Lou Tishang; The edge of described sliding support 5 is provided with L shaped depression, and the end of the upper support section of described precast concrete stair section is provided with the suitable projection of this depression so that the upper support section of described precast concrete stair section is supported on described sliding support.As shown in Figure 1, the upper surface of described sliding support 5 is provided with polytetrafluoroethylene (PTFE) backing plate 2, and the soffit along continuous straight runs of described lower support section is provided with at least two pre-embedded steel slabs 1, and described pre-embedded steel slab 1 interval arranges; The pre-embedded steel slab 1 of the position of the position of described polytetrafluoroethylene (PTFE) backing plate 2 and described pre-embedded steel slab 1 suitable so that described lower support section can slide with respect to described sliding support by this polytetrafluoroethylene (PTFE) backing plate 2.Like this this precast concrete stair section 4 can be installed conveniently.
As shown in Figure 3, be provided with between the sidewall of the lower support section of described precast concrete stair section 4 and described sliding support 5 and fill flexible material isolation strip 3.As shown in Figure 3, also be provided with between this pre-embedded steel slab 1 and fill flexible material isolation strip 3.
In use, only need L shaped projection with the upper support section of this precast concrete stair section 4 to be fixed on L shaped depression on this sliding support 5, then the lower support section of precast concrete stair section 4 is slided into the precalculated position and can complete assembling.
The assembly concrete stair of the employing sliding support that the utility model embodiment proposes, its lower end can and be connected in that between the sliding support of agent structure, occurred level slides, avoided structure when relative storey displacement occurs, stair because of as bearing diagonal stressed occur self destroy in advance and on the impact of agent structure rigidity.The local polytetrafluoroethylene (PTFE) backing plate that arranges of the upper surface at sliding support that the utility model adopts can be used good with the steel plate sliding capability and other good efficient sliding material replacement of self compressive property.In sum, the utility model is the precast concrete stair according to the design of housing industrialization, form of construction work and assembling mode of construction adapt, and are particularly suitable for anti-seismic performance and require high and avoid stair to the demanding building in agent structure adverse effect aspect.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
