Abstract
The utility model provides an assembling type staircase, includes inclined ladder roof beam and a plurality of marking time, the inclined ladder roof beam is steel inclined ladder roof beam, mark time including the steel U -shaped groove of marking time, place prefabricated atress component in it to the concrete filling thing has been pour. The utility model discloses it is continuous with terraced roof beam with welding seam or connecting piece to mark time, assembles the completion in mill or scene. The utility model discloses the sound insulation of marking time high advantage of light, the construction convenience of the dead weight of steel construction stair, assembly rate and concrete stair well, anti -Vibration, advantage that the travelling comfort is strong combine.
Description
Technical field
The utility model relates to building element technical field, is specifically related to a kind of assembled stair.
Background technology
In assembled architecture, assembled stair occupy very consequence in whole building system, stair are as the main vertical transportation of building and main thoroughfare when emergency evacuation, normal use and emergency evacuation on whole building have important impact, and the assemblingization of stair is also one of leading indicator of the assembling rate of assembled architecture. In steel building, although adopt traditional cast-in-situ steel reinforced concrete stair fastness, soundproof effect and non-maintaining on there is greater advantage, but reinforced concrete stairs deadweight is larger, need to carry out the complicated procedures of forming such as formwork, reinforcing bar binding and cast in situs, maintenance, exist the construction period long, concealed work is many, the poor shortcoming of quality controllability; Precast concrete stair, exists from great, need and adopts the shortcomings such as big machinery installation, joint connection in site node complexity, in extension process, is subject to certain restrictions. Assembling type steel structure stair arise at the historic moment for this reason.
Assembling type steel structure stair, have from heavy and light, make the remarkable advantages such as high, the reliable in quality of precision, easy for installation, assembling rate height, but use that comfort level is poor, the insufficient rigidity of marking time, have the defects such as the sound while walking about.
Summary of the invention
The purpose of this utility model is to provide a kind of assembled stair, has the advantage of concrete staircase and steel stair concurrently, can overcome again its stair of shortcoming separately, and have easy construction, from heavy and light, reliable in quality, uses the advantages such as comfortable.
For achieving the above object, the technical solution of the utility model is:
A kind of assembled stair, comprise inclined ladder beam and some marking time; Described in it, inclined ladder beam is steel inclined ladder beam; Described marking time comprises the steel U-shaped groove of marking time, and places precast stressed member, and built Concrete Filled thing in it.
Further, described inclined ladder beam upper and lower side is connected in the brace summer of stair landing or floor by bolt or welding method.
Mark time U-shaped one side edge length of groove of the steel U-shaped of marking time preferably, is greater than another side.
Preferably, described precast stressed member is reinforced mesh.
Preferably, described in, mark time and be bolted or be welded to connect in described inclined ladder beam, formation steel structure stairway.
The beneficial effects of the utility model:
1, the utility model adopts prefabrication ladder beam, step plate, and batch production degree is high; From heavy and light, adopt Simple mechanical to get final product installation, speed of application speed of application is accelerated greatly, be applicable to the construction feature of architectural industrialization.
2, the utility model assembled stair can be removed all loaded down with trivial details Site Template engineerings and reinforcing bar binding engineering from, save artificial and duration; Greatly reduce the concrete operation of building, do not needed concrete mixer to build, made construction environment and condition greatly.
3, the utility model assembling rate is high, and energy-conserving and environment-protective meet the trend of green building.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structure cutaway view of marking time in the utility model embodiment.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, a kind of assembled stair of the present utility model, comprise that inclined ladder beam 1 marks time 2 with some; Wherein, described inclined ladder beam 1 is steel inclined ladder beam; Described marking time 2 comprises the steel U-shaped groove 21 of marking time, and places precast stressed member 22, and build the Concrete Filled thing 23 of pea gravel concreten and cement mortar in it, forms the larger combination of rigidity and marks time.
Further, described inclined ladder beam 1 upper and lower side is connected in the brace summer 3 of stair landing or floor by bolt or welding method.
Preferably, mark time U-shaped one side edge length of groove 21 of 2 the steel U-shaped of marking time described in is greater than another side.
Preferably, described precast stressed member 22 is reinforced mesh.
Preferably, described in mark time and 2 be bolted or be welded to connect in described inclined ladder beam 1, form steel structure stairway.
Claims (5)
