Abstract
The utility model discloses a modularized steel corrugated plate step structure. The modularized steel corrugated plate step structure comprises profile steel ladder beams and steps which are arranged between the profile steel ladder beams and are regularly arranged, wherein the steps are detachably arranged between the two profile steel ladder beams as modularized step units; each modularized step unit is provided with two side plates and one kicking baffle; the two side plates are oppositely arranged and respectively provided with a connecting mechanism which is connected with the profile steel ladder beams; the kicking baffle is arranged at the front ends of the two side plates; a space enclosing structure between the kicking baffle and the two side plates is provided with a corrugated plate for walking. By adopting the corrugated plates with specific corrugations, a landing slab has excellent anti-shearing and fatigue-proof properties, and is light in self weight and good in rigidity. Due to modularization of the steps, the overall staircase is assembled on site through bolts, and each unit is light in weight without the need of using hoisting equipment, thus being time-saving, effort-saving and economic. Furthermore, the steps and the ladder beams are connected through the bolts, so that on one hand, a great amount of on-site welding workload can be reduced, on the other hand, the staircase is directly assembled without welding, thus being unlikely to deform, and easily ensuring the overall quality.
Description
Technical field
The utility model relates to the construction steel structure technical field, especially relates to a kind of modular ripple slab tread structure.
Background technology
The construction steel structure field especially in similar field at present, traditional steel stair is marked time the normal checkered steel plate that adopts by cold roll forming, and then the mode by welding is connected in aggregates with terraced beam.Because marking time of bending forming touched face length with shaped steel ladder beam, so welding capacity is large, often easily causes welding deformation, distortion etc., and total quality is not too high.What checkered steel plate was made marks time, the large and rigidity disproportionate of weight, economy deficiency.Also have a bit, because welding capacity is large, for ensuring the quality of products, stair are all that factory makes an integral body and transports on-the-spot the installation to usually, cause monomer members weight large, and scene needs the lifting appliance such as crane to install.And scene often just starts to install stair in the engineering later stage, build a lot of places and seal, cause stair that difficulty is installed.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, provide a kind of simple in structure, easy for installation, operation is less, the modular ripple slab tread structure of economical rationality.
To achieve these goals, the utility model adopts following technical scheme:
Modular ripple slab tread structure, this ripple slab tread structure is by shaped steel ladder beam and be located between shaped steel ladder beam and regularly arranged marking time forms, it is characterized in that,
Described marking time removably is assembled between amphitypy steel ladder beam with the modularization unit of marking time;
The described modularization unit of marking time has:
Two side plates of positioned opposite, its be provided with shaped steel ladder beam between the bindiny mechanism that is connected;
Be installed on the skirt baffle plate of biside plate front end;
Space enclosing structure between skirt baffle plate and two side plates is equipped with the corrugated sheet for walking.
Wherein, described bindiny mechanism is cavernous structure/hanging structure, and shaped steel ladder beam has the pilot hole/mount hole with cavernous structure/hanging mechanisms coupling, and modularization is marked time and adopted the bolt splicing to install/articulate installation between unit and shaped steel ladder beam.
Wherein, described corrugated sheet is by the cold rolling moulding of hot rolled plate.
Wherein, the section of described corrugated sheet is shape in echelon, and the wavelength of each trapezoidal ripple is 188mm, and wave height is 40mm.
Wherein, the thickness of described corrugated sheet is 1.5～3mm.
Wherein, the width of the described unit of marking time is 250～300mm.
Wherein, it is vertical that the ripple of described corrugated sheet moves towards direction and shaped steel ladder beam arranged direction.
Compared with prior art, the utlity model has following beneficial effect: the utility model adopts modules of composition such as a kind of corrugated sheet of specific waveforms and skirt baffle plate to mark time.Due to the corrugated sheet of landing slab plate employing specific waveforms, it has good shearing resistance, fatigue performance, and from heavy and light, good rigidity.And the modularization of marking time, whole stair are to lead at the scene the limit bolt to assemble, the very light in weight of each unit, installed without lifting appliance.Time and labour saving is very good on economy.And, mark time and be bolted with terraced beam, one has reduced a large amount of Site Welding workloads, and two because of welding, and direct-assembling forms, not yielding, and total quality is more easily to be guaranteed.
The accompanying drawing explanation
Fig. 1 is modular ripple slab tread structure assembled state figure.
Fig. 2 is the mark time structural representation of unit of modularization in modular ripple slab tread structure.
Fig. 3 is that in modular ripple slab tread structure, corrugated sheet does not cut previous structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figures 1 to 3, modular ripple slab tread structure, this ripple slab tread structure is by shaped steel ladder beam and be located between shaped steel ladder beam 5 and regularly arranged marking time forms, described marking time removably is assembled between amphitypy steel ladder beam with the modularization unit of marking time, demountable structure comprises the bolt mounting structure and articulates mounting structure, and the bolt mounting structure is selected in this case; The modularization that width the is 250～300mm unit of marking time has: positioned opposite and as two side plates 2 of terraced beam junction plate, its be provided with shaped steel ladder beam between the bindiny mechanism that is connected, this bindiny mechanism is for being located on side plate for the use of assembling bolt 4, and for side plate, it adopts square plate; Be installed on the skirt baffle plate 3 of biside plate front end, the lower edge of two side plates is stretched out slightly in order to mutually be connected with the modularization unit of marking time in its underpart; Space enclosing structure between skirt baffle plate and two side plates is equipped with the corrugated sheet 1 for walking, this corrugated sheet section is shape in echelon, the wavelength of each trapezoidal ripple is 188mm, wave height is 40mm, thickness is 1.5～3mm, it is vertical with shaped steel ladder beam arranged direction that the ripple of corrugated sheet moves towards direction, and whole corrugated sheet is by the cold rolling moulding of hot rolled plate.
Referring to Fig. 1, the unit of marking time described in the utility model, adopt modularization making, and a unit is a module, adopts the mode of on-the-spot bolt splicing, and abandoning tradition welded and installed mode, so removed all drawbacks of bringing because of welding manner from.
The foregoing is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not break away from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
