Abstract
The two badly bleeding stair of a kind of two circular hollow steel column supporting, by two circular hollow steel columns, stair girder steel, stringer, landing beam, tread, landing slab, railing forms, it is characterized in that: load-bearing steel column adopts two circular hollow posts, steel column and infrastructure adopt and are rigidly connected, the structural system that connection beam forms twin columns frame stability is set between two circular hollow steel columns, stair girder steel, landing beam adopts the real abdomen girder steel of H type, stringer adopts grooved girder steel, stair girder steel, landing beam and circular hollow steel column adopt ring set gusset plate bolt to splice at position, upper lower flange, web place is connected with vertical stiffener bolt on circular hollow steel column, all with bolts between stringer and stair girder steel, between tread and stringer.The utility model reasonable stress, good looking appearance, antiseptic property are good, the durability of structure also can be protected, and assembly operation is convenient, and cost economic, practicality is superpower.
Description
Technical field
The utility model relates to the new arrangement structural system of vertical channel-staircase in civil buildings and industrial building, is particularly useful for Power Plant Buildings structure thing as grey storehouse stair, the absorption tower stair of desulfurization building, the part stair etc. in main building.
Background technology
Stair are as the vertical channel in building, and its position, structural shape and space layout have a certain impact to building using function tool, and the convenience etc. of its constructing operation also plays certain influence effect to the completion time of project of building simultaneously.
Traditional staircase is generally made up of the platform post of main load-bearing four pillars, inclined ladder section, stair stringer, half space, half space beam and its necessity; Often adopt monolithic reinforced concrete structure, the vertical passageway in building prior to agent structure construction, according to layout demand, will make template, formwork, assembling reinforcement, cast concrete, curing concrete, reaching concrete hardening the length of time can form removal use.For concrete staircase, construction period the safety devices such as banister still need and by the time enter the interior decoration phase and can install, the construction period must install interim substitute.Such stair make trouble, and the construction period is long, and dead load is large, and owing to considering the endurance quality requirement that structure uses, stair concrete and rebar consumable quantity is very large.In order to make, stair are safe and reliable, layout is more flexible, structure stress is more reasonable, and construction more succinctly facilitates, and achieves the goal with regard to needing a kind of new version.
Utility model content
The purpose of this utility model transforms existing stair layout and version, according to the design feature of stair, under the prerequisite meeting using function requirement, adjustment stair load-carrying members form and structure model selection, make that stair using function is more perfect, structure stress is more reasonable, bench assembling is more convenient, and cost is more economical.
For achieving the above object, the utility model provides a kind of two circular hollow steel column supporting two badly bleeding stair, by two circular hollow steel columns, stair girder steel, stringer, landing beam, tread, landing slab, railing forms, it is characterized in that: load-bearing steel column adopts two circular hollow posts, steel column and infrastructure adopt and are rigidly connected, the structural system that connection beam forms twin columns frame stability is set between two circular hollow steel columns, stair girder steel, landing beam adopts the real abdomen girder steel of H type, stringer adopts grooved girder steel, stair girder steel, landing beam and circular hollow steel column adopt ring set gusset plate bolt to splice at position, upper lower flange, web place is connected with vertical stiffener bolt on circular hollow steel column, all with bolts between stringer and stair girder steel, between tread and stringer.
The utility model adopts two steel column acting in conjunction to bear the load of total, and circular hollow steel column cross section isotropism, reasonable stress, good looking appearance, antiseptic property are good, the durability of structure also can be protected.Bench and half space, around two steel columns, are absolute construction system, structural elements produce in factory, and step plate can arrange tread plate or adopt special substance, and adopt flexible bolt to be connected with stringer, overall structure Assembling can complete.This kind of staircase structure had both been applicable to be arranged in be closed in building, also can be arranged in outdoor.Monolithic stability realizes by arranging necessary horizontal support with agent structure, and structure stress is reasonable, and arrange dexterous, between steel beam column, major part is with bolts, and assembly operation is convenient, and cost economic, practicality is superpower.
