Description
Technical field
The present invention relates to a kind of building structure, especially a kind of light steel grating concrete folding stair.
Background technique
Currently, after with the national and local relevant policies put into effect development assembled architecture in succession, promote building industrialization,
Prefabrication enters a fast-developing new period, and various prefabrication structures go out like the mushrooms after rain
It is existing, such as prefabricated assembled concrete structure, prefabricated assembled lightweight steel construction, non-dismantling formwork structural system.But various systems exist
Many problems are all encountered in practical application, is widely applied to prefabrication and causes difficulty, such as assembled coagulation
Soil structure has that prefabricated rate is generally relatively low in application process, and construction technology is incomplete, the wet construction scale of construction of node connection is big
The problems such as influencing duration and cost, construction cost higher than traditional cast-in-place structural；Structure with assembled lightweight steel does not obtain in China
Be widely applied, main cause, which is client, to be had such system and misread, it is believed that lightweight steel construction system similar to board house, shaky, because
This acceptance is not high；Non-dismantling formwork structural system cannot participate in structure stress and pour to be not easy to remove after the completion to make because of template system
Building is influenced at the increase of structural elements size to use.Stair are universal in the application of prefabrication, but traditional pre-manufactured steel
Reinforced concrete stair lift weight weight, and monolithic gangboard weighs about 2-3t, and node connection is complicated, cast-in-place to be easy with precast spliced place
Existing crack；Although steel stair can be easier to realize prefabricated, for anaphase effect using poor, noise is larger.
Summary of the invention
The present invention be solve technical problem present in well-known technique and provide a kind of lifting light weight, speed of application fastly,
The light steel grating concrete folding stair of good economy performance, good integrity.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of light steel grating is mixed
Solidifying soil overlapping stair, including cement fibrolite plate stair bed die and cement fibrolite plate stair side form and light steel grating stair inclined plate bone
Frame, the light steel grating stair inclined plate skeleton are that the steel bar girder or lightgage steel joist longitudinally extended by multiple along stair is constituted,
Each steel bar girder or lightgage steel joist are connect with the cement fibrolite plate stair bed die, all steel bar girders or light
Steel joist is connected by being welded on the multiple tracks transverse direction steel plate at the top of it, the road number and the number phase of stair step of the transverse direction steel plate
Together, it is connected with stair step skeleton on the lateral steel plate, is connected with cement fibrolite plate on the stair step skeleton and steps on
Walk vertical plate；The cement fibrolite plate stair side form is connected to the light steel grating stair inclined plate skeleton and the stair step skeleton
On, a cement fibrolite plate stair bed die, two cement fibrolite plate stair side forms and multiple cement fibrolite plates
Vertical plate of marking time constitutes cement fibrolite plate stair mould, and concrete solid has been poured in the cement fibrolite plate stair mould, described mixed
Solidifying soil entity, the cement fibrolite plate stair mould, the light steel grating stair inclined plate skeleton and the stair step skeleton are folded
It is combined into entirety, forms the overlapping stair of whole stress.
Cement fibrolite plate is also connected on the stair step skeleton to mark time plate.
It is equipped in the cement fibrolite plate stair mould additional with the common stress of the light steel grating stair inclined plate skeleton
Steel bar stress.
The lightgage steel joist is using made of any one profile in channel steel, H profile steel, U-shaped steel and Fang Tong.
Multiple concrete flowing holes laterally penetrated through are equipped on the lightgage steel joist.
The steel bar girder is affixed by the junction steel plate and the cement fibrolite plate stair bed die for being welded on its bottom.
The advantages and positive effects of the present invention are: greatly reducing and applying using light steel grating concrete folding structure
The precast stair at work scene lifts weight, makes construction process economic security；Production flexibly, can prefabrication, and factory can be moved
To scene, assembled architecture can be achieved with without throwing huge fund construction precast concrete factory.In addition, in the construction stage, light steel
Grid stair inclined plate skeleton bears construction loads, and template of the cement fibrolite plate as casting concrete can accomplish that zero template makes
With, a large amount of form rentings expense can be saved, template is dismantled and have bad luck the expense of template, save installation full hall scaffold expense and
Time greatly shortens the construction period, and reduces project cost.After the completion of concreting, light steel grating stair inclined plate skeleton, Cement fibre
Plate and concrete folding are whole, common stress, light steel grating stair inclined plate skeleton play in conventional steel bar concrete component by
The effect of power reinforcing bar, overlapping can be unworthy of in stair or less with reinforcing bar, live reinforcing bar binding connection work can be greatly reduced.And
Light steel grating concrete folding stair and light steel grating concrete folding plate seam crossing good integrity, later period using effect are good.It is comprehensive
On, light steel grating concrete folding stair can achieve the requirement for taking into account economy, duration and client's acceptance, be a kind of tool
The stair type having wide application prospects.
