Abstract
The invention discloses a combined assembled type stairway, and belongs to the field of building structures. The combined assembled type stairway is composed of a prefabricated section steel ladder beam and prefabricated reinforced concrete steps, wherein the prefabricated section steel ladder beam is composed of two section steel supporting sloped beams and angle steel supports which are evenly spaced and are correspondingly connected with the inner sides of the two supporting sloped beams, and the bottom faces of the angle steel supports are horizontally arranged; the prefabricated reinforced concrete steps are composed of inverted-L-shaped unit reinforced concrete benches, and the inverted-L-shaped unit reinforced concrete benches are provided with horizontal pedal faces and vertical supporting faces perpendicular to the horizontal pedal faces; on the scene, the horizontal pedal faces of the inverted-L-shaped unit reinforced concrete benches are arranged on the corresponding angle steel supports of the section steel ladder beam, the vertical supporting face of the first level of inverted-L-shaped unit reinforced concrete bench is supported on the ground, and the other levels of inverted-L-shaped unit reinforced concrete benches are sequentially supported on the next level inverted-L-shaped unit reinforced concrete benches, the relevant connection gaps are filled with mortar, and therefore the stairway is formed. The stairway is firm, durable in use, convenient to dismount and capable of being repeatedly used.
Description
Technical field
A kind of combination assembled stair of the present invention, belong to building structure field.
Background technology
Stair are the important ingredients of building, according to form of structure or material difference, have various forms.Conventional stair mostly are reinforced concrete stairs or steel stair now, reinforced concrete stairs is divided into again cast-in-situ steel reinforced concrete stair and prefabricated reinforced concrete stair, it is complicated that the constructions such as support and template, assembling reinforcement, cast-in-situ concrete are set up at cast-in-situ steel reinforced concrete stair scene, curing time is long, the prefabricated reinforced concrete stair once prefabricated straight stairs that adopt, make complexity, inconvenience and transportation difficulty are installed more.Though steel structure stairway is can prefabrication on-the-spot install involve great expense, functional performance is poor, trouble is installed.Existing stair form can not meet industrialization of construction industry for building operations modularization, prefabricated, standardized demand.
Summary of the invention
The object of this invention is to provide a kind of combination assembled stair, prefabricated and install to realize the batch production of architectural stair, not only improve efficiency of construction and quality, be more conducive to promote modularization, the standardization of assembled architecture.
The present invention is achieved by the following technical solutions:
A kind of combination assembled stair of the present invention, by precasting steel ladder beam and prefabricated reinforced concrete step, formed, described precasting steel ladder beam is comprised of two type steel support cant beams and angle steel crossbeam, angle steel girder space is connected between two type steel support cant beams, described two support cant beam inner sides evenly interval correspondence are connected with angle seat, and the bottom surface of each angle seat is horizontally disposed with; Described prefabricated reinforced concrete step is comprised of ┓ type unit steel concrete stage, and this ┓ type unit steel concrete stage has vertical each other horizontal step face and vertical supporting surface; At the scene, shaped steel ladder beam is by setting tilting installation, from bottom to up, the horizontal step face of ┓ types at different levels unit steel concrete stage is arranged on the corresponding angles steel support of shaped steel ladder beam, the vertical supporting surface of first order ┓ type unit steel concrete stage is supported on ground, the vertical supporting surface correspondence of all the other stages at different levels is supported in its next stage ┓ type unit steel concrete stage, fills after mortar moulding stair at the relevant connection gap location of installing.
The length of described ┓ type unit steel concrete stage is corresponding with the spacing of two type steel support cant beams of shaped steel ladder beam.
The external surface of described ┓ type unit steel concrete stage posts face brick.
Two type steel support cant beams of described shaped steel ladder beam are by channel-section steel, i iron or other cross section section steel manufactures.
A kind of combination assembled stair of the present invention, precasting steel ladder beam and prefabricated reinforced concrete step are all prefabricated in the factory, on-the-spot installation, reduce on-site construction processes and work difficulty, reduce situ wet workload, save the construction period; Prefabrication precision is higher, and modularization, standardization more easily realize; Shaped steel ladder beam and other members of structure have good connectivity; When being prefabricated in the factory, steel concrete step plate face brick paving can be completed, without secondary patch block; Remaining basically stable in shaped steel ladder beam and step bottom, reduces taking headroom; This combination assembled stair are sturdy and durable, easy accessibility, can reuse, not only environmental protection but also save cost.
