Abstract
A kind of steel structure stairway step plate, described step plate is formed by the steel plate bending that one piece of 2mm～3mm is thick, the cross sectional shape of step plate is that two ends are respectively with vertical right angle flanging (1) and the L-type plate of level right angle flanging (2), vertically right angle flanging (1) is positioned at horizontal plate (3) outer end of L-type plate and is folded to top, level right angle flanging (2) is positioned at vertical plate (4) top of L-type plate and is folded to outside, is machined with prepared screw-bolt hole (5) at four angles of the horizontal plate (3) of L-type plate.This utility model processing is simple, be not required to welding, can scene be the most assembled, easy for installation, deadweight is relatively light, saving steel.
Description
Technical field
This utility model relates to steel stair step plate technical field of structures.
Background technology
China carries out green building energetically, and steel construction, as the product of green building, has superior performance, can
Duration is greatly shortened, reaches industrialization and produce.Traditional steel structure stairway step plate is by welding and ladder beam
Connecting, cross sectional shape is simple L-type, and steel plate thickness is typically not less than 5mm, and steel plate upper strata is by paving
If steel fabric sheet and 50mm concrete provide integral rigidity.Fill real in order to ensure concrete, need to be to each
Level step carries out formwork, and the height of step and width, mostly all without identical, cause waste, nothing to template
Method accomplishes recycling.Additionally, due to conventional steel structure stair step is thicker, generation from great, mark time
Plate each item data surplus capacity is more, causes steel stair cost far above concrete staircase.Based on these present situations,
Current steel stair is marked time heavier, and wasteness is big, and size modulus is indefinite, it is impossible to accomplish mass production.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of processing is simple, be not required to welding,
Can the most assembled, easy for installation on-the-spot, relatively light, the steel structure stairway step plate of saving steel of conducting oneself with dignity.
The technical solution adopted in the utility model is as follows:
A kind of steel structure stairway step plate, described step plate is formed by the steel plate bending that one piece of 2mm～3mm is thick,
The cross sectional shape of step plate is the two ends L-type plates respectively with vertical right angle flanging and level right angle flanging, vertically
Right angle flanging is positioned at the horizontal plate outer end of L-type plate and is folded to top, and level right angle flanging is positioned at the perpendicular of L-type plate
Straight plate top is also folded to outside, is machined with prepared screw-bolt hole at four angles of the horizontal plate of L-type plate.
The steel plate making step plate is kept to by this utility model by the 5mm thickness checkered steel plate of prior art
The steel plate that 2mm～3mm is thick, effectively alleviates deadweight, and can meet code requirement, by steel performance
Change greatly utilization.Step plate two ends after bending, with flanging, increase cross sectional moment of inertia, make step plate fine
Bear moment of flexure shearing.This utility model can on-site consolidation, it is no longer necessary to welding, reduces cost of transportation,
Assemble flexibly and can reuse.Spillage phenomenon also will not be produced when casting concrete surface layer.
This utility model can carry out modularization, producing in serial form, and processing is simple, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
With process equipment, the direct bending of steel plate that one piece of 2mm～3mm is thick is formed shape as shown in Figure 1 and Figure 2
The step plate of shape, the cross sectional shape of step plate is that two ends carry vertical right angle flanging 1 and level right angle flanging 2 respectively
L-type plate step plate, vertical right angle flanging 1 is positioned at horizontal plate 3 outer end of L-type plate and is folded to top, water
Straight angle flanging 2 is positioned at vertical plate 4 top of L-type plate and is folded to outside, at the horizontal plate 3 of L-type plate
Four angles are machined with prepared screw-bolt hole 5.
Step plate of the present utility model plays template action, by the vertical plate height side of up-down adjustment L-type plate
To size, making to mark time meets different building height requirement, meets difference by the vertical concrete thickness of regulation and steps on
Step width requirement, the prepared screw-bolt hole that step plate is offered is to be connected for the bolt of step plate with terraced beam, spiral shell
Bolt bears shearing, it is ensured that with the compact siro spinning technology of ladder beam, concrete provides the rigidity needed for stair, meets comfortable
Degree requirement.
The problems such as this utility model can be widely used in dwelling house system, removes stair formwork erecting difficulty from, installation difficulty.
