Abstract
The utility model provides an assembling type staircase of a steel-structure main workshop. The assembling type staircase is characterized by comprising a steel column, a steel beam, steel ladder beams, assembling type pedal plates, pre-embedded pieces and supporting angle steel, wherein the steel ladder beams are supported on a steel framework composed of the steel column and the steel beam; the supporting angle steel is welded on the steel ladder beams by blocks; the assembling type pedal plates are placed on the supporting angle steel in sequence; the pre-embedded pieces pre-embedded at the two ends of the assembling type pedal plates and the supporting angle steel are welded to fix the assembling type pedal plates. The assembling type staircase of the steel-structure main workshop is simple in connection nodes and very convenient to construct; the construction speed is increased greatly and the construction period is shortened.
Description
Technical field
the utility model relates to stair, especially relates to a kind of assembly concrete bench stair for steel work main building.
background technology
The coal-fired power plant's main building designing at present, domestic have part to adopt steel work, and the external project overwhelming majority adopts steel work.In the steel work main building of coal-fired power plant, flooring and stair adopt monolithic reinforced concrete structure.Floor plate, because be horizontal arrangement, adopts profiled sheet to make bed die, and construction is got up more convenient.But stair bench is not level, cannot adopt profiled sheet to make bed die.The height of main building stair is generally in 40m left and right, and highly higher, bench angle is different, and template is complicated, constructs very inconvenient.Especially abroad in project, because each side condition is not as domestic facility, manpower and equipment lack, and the construction of stair tends to affect the duration.If adopt steel step plate (checkered steel plate or steel grating plate), construct really more convenient, but as the main stair of main building, comfortableness is poor, the also bad solution of while fire safety problem.If brushing fireproof paint, because the current fireproof paint for people or material easily weares and teares, does not have due effect in bench position.If employing fireproof decorative top, cost can be higher.
Utility model content
The purpose of this utility model is to provide a kind of simply and easily for the assembly concrete bench stair of steel work main building, to save material, accelerates the speed of application of stair.
For achieving the above object, the utility model provides a kind of steel work main building assembling stair, it is characterized in that: comprise steel column, girder steel, steel ladder beam, assembling step plate, built-in fitting, supporting angle steel, steel ladder beam support is on the steel frame being comprised of steel column and girder steel, supporting angle steel piecemeal is welded on steel ladder beam, assembling step plate is placed on supporting angle steel successively, is embedded in the built-in fitting at assembling step plate two ends and supporting angle steel welding in order to fixing assembling step plate.
Assembling step plate adopts prefabricated trough slab.
The utility model connected node is simple, constructs very convenient.Because it has been cancelled the work of formwork and has adopted precast concrete step plate, can realize prefabricated limit, limit and install, improved greatly speed of application, saved the duration.Visible for steel work main building stair, adopt assembly concrete bench stair to there is extraordinary economic benefit and social benefit.It is a trough slab that every one-level is marked time, at different levels mark time measure-alike, template sizing, piecemeal is made, efficiency is higher.Because scantling is less, less demanding to prefabricated place in addition, at the scene just can be prefabricated.The flute profile profile of marking time is reasonable, alleviates deadweight, has saved material, has strengthened moment of inertia simultaneously, has improved the bending resistance of marking time.Stair template is complicated, expends the plenty of time, owing to having adopted prefabricated member, does not need on-the-spot formwork, has saved a large amount of formwork time.The weight of every one-level step plate is less, is convenient to install, and just bench can be placed on the supporting angle steel that is welded on steel ladder beam, and be welded to connect with it by easy boom hoisting, has improved greatly speed of application.The steel member brushing that exposes is anticorrosion and fireproof paint convenient, and in concealed location, is not easy wearing and tearing.
Accompanying drawing explanation
Fig. 1 is stair layout plans;
Fig. 2 is assembling bench longitudinal sectional drawing;
Fig. 3 is assembling bench transverse cross-sectional view.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises steel column 1, girder steel 2, steel ladder beam 3, assembling step plate 4, built-in fitting 5, supporting angle steel 6, stiffening rib 7, first steel ladder beam 3 is bearing on the steel frame being formed by steel column 1 and steel column 2, then by designing requirement, supporting angle steel 6 piecemeals are welded on steel ladder beam 3, assembling step plate 4 is placed on supporting angle steel successively, the built-in fitting 5 that is embedded in assembling step plate 4 two ends welds with supporting angle steel 6 scenes, with fixing assembling step plate 4.6 booster actions of 7 pairs of supporting angle steels of stiffening rib.Then and fireproof paint anticorrosion to the steel member brushing exposing.Prefabricated like this step plate is just arranged on steel ladder beam easily.
Claims (2)
1. steel work main building assembling stair, it is characterized in that: comprise steel column, girder steel, steel ladder beam, assembling step plate, built-in fitting, supporting angle steel, steel ladder beam support is on the steel frame being comprised of steel column and girder steel, supporting angle steel piecemeal is welded on steel ladder beam, assembling step plate is placed on supporting angle steel successively, is embedded in the built-in fitting at assembling step plate two ends and supporting angle steel welding in order to fixing assembling step plate.
2. a kind of steel work main building assembling stair according to claim 1, is characterized in that: assembling step plate adopts prefabricated trough slab.
