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, have various forms according to form of structure or material difference.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 transport 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, formed by precasting steel ladder beam and prefabricated reinforced concrete step, described precasting steel ladder beam is made up 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 made up 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.

Detailed description of the invention
Now further illustrate by reference to the accompanying drawings implementation process of the present invention.
A kind of combination assembled stair of the present invention, formed by precasting steel ladder beam 2 and prefabricated reinforced concrete step 1, described precasting steel ladder beam 2 is made up of two type steel support cant beam 2-1 and angle steel crossbeam 2-2, and angle steel crossbeam 2-2 interval is connected between two type steel support cant beam 2-1, described two support cant beam 2-1 inner side evenly interval correspondence be connected with angle seat 2-3, this angle seat 2-3 has bottom surface 2-3a, side 2-3b, is horizontally disposed with and supports cant beam 2-1 inner side and be connected by the bottom surface 2-3a of each angle seat 2-3, described prefabricated reinforced concrete step 1 is made up of ┓ type unit steel concrete stage 1-1, and this ┓ type unit steel concrete stage 1-1 has vertical each other horizontal step face 1-1a and vertical supporting surface 1-1b, in erecting bed, by tilting by setting shaped steel ladder beam 2, after its upper and lower two ends fixed installation, again the horizontal step face 1-1a of first order ┓ type unit steel concrete stage 1-1 is arranged on two type steel support cant beam 2-1 corresponding angles steel support 2-3 of shaped steel ladder beam, its vertical supporting surface 1-1b supports on the ground, then, successively the horizontal step face 1-1a of ┓ type unit steel concrete stage 1-1 is arranged on corresponding angles steel support 2-3 from bottom to top, its vertical supporting surface 1-1b correspondence is supported on its prime ┓ type unit steel concrete stage 1-1, finally, fill mortar 3 at the relevant connection gap location of installing, be the combination assembled stair of moulding.
The length of described ┓ type unit steel concrete stage 1-1 is corresponding with the spacing of two type steel support cant beam 2-1 of shaped steel ladder beam 2.
The external surface of described ┓ type unit steel concrete stage 1-1 posts face brick 1-2.
Two type steel support cant beam 2-1 of described shaped steel ladder beam 2 are by channel-section steel, i iron or other cross section section steel manufactures.
