Description
Technical field
The utility model relates to a kind of precast stair, particularly relates to a kind of for the industrialization of construction industry pin-connected panel precast stair structure in building.
Background technology
Industrialization of construction industry refers to the large industrial mode of production by modern manufacture, transport, installation and scientific management, that replace low-level in traditional architecture industry, dispersion with the handicraft mode of production that is poor efficiency.So the preparation of industrialization of industrialization of construction industry pin-connected panel precast stair should meet the theory of industrialization of construction industry, there is the unified feature of producing, being convenient to transport, be convenient to lifting, Accelerating The Construction speed, raising construction precision and reduce resource consumption.
But a large amount of building operations problem investigation finds, under industrialization of construction industry background, the precast stair weight of global formation is comparatively large, and hoisting difficulty is large; Further, the precast stair of global formation takes up room comparatively large, transport and installation comparatively difficulty.These factors govern the development of industrialization of construction industry, specifically there is following shortcoming and defect:
1. transport is more difficult, and cost is higher.The precast stair of global formation takies volume greatly, out-of-shape, and free spaces a large amount of in transportation is wasted, and causes the waste of resource;
2. lifting difficulty.When highrise building lifting weighs the body formed precast stair of the one-tenth of several tons, by wind impact is comparatively large, just can cannot lift because rocking violent, bringing extreme difficulties to construction when wind-force reaching more than three grades;
3. inconvenience is installed.The precast stair of global formation will take large quantity space when installing, and causes working space narrow and small, affects construction speed;
4. the seismic measures of common precast stair mainly concentrates in the design of the shock-resistant node that stair two ends are connected with platform, and ignores the possible distortion power consumption potentiality of stair itself, affects anti seismic efficiency.
Utility model content
For above-mentioned technical problem, the utility model is intended to solve the problems of the technologies described above to a certain extent.
The purpose of this utility model be to provide a kind of dismantled and assembled, cost is low, easy construction, can repetition produce and the good industrialization of construction industry pin-connected panel slab type stairway structure of anti seismic efficiency in batches.
For solving the problem, the utility model adopts following technical scheme:
A kind of precast splice type slab type stairway, comprise the stepped gangboard component of the several piece of splicing successively from left to right, described stepped gangboard component is reinforced concrete member, comprises stair tread and is positioned at the several longitudinal stringer below stair tread.
Further, the junction of adjacent steps shape gangboard component is provided with the rubber abaculus that can mutually be fitted together in couples, comprise recessed piece and projection, the two can be fitted together to dimensionally, and the shape of described recessed piece and projection is corresponding with the side edge shape of described stepped gangboard component.
Further, described recessed piece all adopts arc transition with the corner of projection, has both been convenient to install, and also prevents stress in use procedure from concentrating and fatigue damage.
Compared with prior art, the beneficial effects of the utility model are:
1., by stair are split as several parts, will promote scale and the repetition of production to meet industrialization spirit, also more economical;
2., due to component shape rule, single quality is less, will effectively reduce transport difficulty and cost of transportation;
3. due to the fractionation of parts, hoisting difficulty also can reduce greatly, can be divided into and repeatedly transport on a small quantity in the weather that wind-force is stronger;
4. parts fractionation and re-assembly and will provide a large amount of working spaces when mounted, reduce install difficulty;
5. the rubber abaculus between monomer members makes there is certain mobile space between component, can effective loss seismic energy.Component can not damage when earthquake simultaneously in addition, alleviates the impact of earthquake on staircase structure
6., under the condition ensureing stress performance, stair deadweight can be alleviated, reduce construction costs.

Detailed description of the invention
Be described in further detail utility model object of the present utility model below in conjunction with the drawings and specific embodiments, embodiment can not repeat one by one at this, but therefore embodiment of the present utility model is not defined in following examples.
As shown in Figures 1 to 8, a kind of precast splice type slab type stairway, comprise three blocks of stepped gangboard components spliced successively from left to right: stepped left gangboard component 1, stepped middle gangboard component 2 and stepped right gangboard component 3, described stepped left gangboard component 1, stepped middle gangboard component 2 and stepped right gangboard component 3 are reinforced concrete member, comprise stair tread 6 and be positioned at the stringer 7 of two longitudinal directions below stair tread 6, described stepped left gangboard component 1, stepped middle gangboard component 2 and the stepped upper right side of right gangboard component 3 and the extension of lower-left end are individually fixed on stair plaform.
Further, what the junction of described stepped left gangboard component 1, stepped middle gangboard component 2 and stepped right gangboard component 3 was paired is provided with the rubber abaculus that can mutually be fitted together to, comprise recessed piece 5 and projection 4, the two can be fitted together to dimensionally, and the shape of described recessed piece 5 and projection 4 is corresponding with the shape of the side of described stepped left gangboard component 1, stepped middle gangboard component 2 and stepped right gangboard component 3.The connecting portion of two adjacent gangboard components is respectively arranged with corresponding rubber abaculus, recessed piece 5 and projection 4 are fitted together to mutually, the mutual slip between stepped gangboard and dislocation can be prevented, again can effective loss seismic energy, and component can not damage when earthquake simultaneously, alleviate the impact of earthquake on staircase structure.
