Abstract
The utility model discloses a kind of steel construction cast-in-place concrete stair, including two steel stair supports for being used to support step plate, the steel stair support is triangle frame, two steel stair supports are placed through tie-beam connection parallel, a swash plate is equipped between two cant beams of two steel stair supports, being erect on the swash plate has polylith to be used for step plate riser, swash plate in front of step plate riser is provided with a through hole, the step plate riser is provided with a bolt hole, being set up between through hole and bolt hole has a stay bolt, the stay bolt and swash plate are at a right angle, a space groove for being used for placing concrete is formed between every piece of step plate riser and swash plate, fill concrete in the space groove, rubber antiskid layer is equipped with positioned at concrete upper surface.The steel construction cast-in-place concrete stair design structure is simple, and step plate riser is mashed up with concrete, plays and the bearing capacity marked time greatly improved after strengthening cast-in-place concrete, moreover it is possible to play a part of antidetonation noise reduction to entirely marking time.
Description
Technical field
Building field is the utility model is related to, specifically a kind of steel construction cast-in-place concrete stair.
Background technology
Existing steel structure stairway step plate is direct casting concrete in steel plate bending part, and moulding is coarse single, unsightly,
Cast-in-place concrete and steel are marked time, and cementability is poor, and big city has been grown or shaken to the time separates concrete and steel plate, can not
Steel plate and concrete is allowed to link into an integrated entity, original skid resistance of marking time is poor, can not meet due antiskid function of marking time.Therefore it is directed to
Above mentioned problem is the object of the utility model research.
Utility model content
The purpose of this utility model is to provide a kind of steel construction cast-in-place concrete stair, the steel construction cast-in-place concrete building
Terraced design structure is simple, and step plate riser is mashed up with concrete, plays and holding of marking time greatly improved after strengthening cast-in-place concrete
Loading capability, moreover it is possible to play a part of antidetonation noise reduction to entirely marking time.
The technical solution of the utility model is：A kind of steel construction cast-in-place concrete stair, including two stepped on for support
The steel stair support of plate is walked, the steel stair support is triangle frame, and two steel stair supports are placed through tie-beam connection parallel,
A swash plate is equipped between two cant beams of two steel stair supports, being erect on the swash plate has polylith to be used for step plate riser, is located at
Swash plate in front of step plate riser is provided with a through hole, and the step plate riser is provided with a bolt hole, through hole and bolt hole it
A structure of an essay is provided with a stay bolt, and the stay bolt and swash plate are at a right angle, and one is formed between every piece of step plate riser and swash plate and is used to pour
The space groove of concrete is filled, fill concrete in the space groove, rubber antiskid layer is equipped with positioned at concrete upper surface.
The utility model has the advantage of：First, the steel construction cast-in-place concrete stair design structure is simple；Second, mark time
Plate riser is mashed up with concrete, plays and the bearing capacity marked time greatly improved after strengthening cast-in-place concrete, moreover it is possible to entirely stepping on
Step plays a part of antidetonation noise reduction；Third, concrete upper surface is equipped with rubber antiskid layer, good antiskid effect；Fourth, the steel construction
Cast-in-place concrete stair is so designed that safety coefficient height, and stability is good, long lifespan.
Brief description of the drawings
Fig. 1 is the steel construction cast-in-place concrete stair schematic diagram in embodiment.
Embodiment
For features described above and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below, but the utility model is not limited to this.
With reference to legend 1, a kind of steel construction cast-in-place concrete stair, including two steel stair supports for being used to support step plate
5, the steel stair support 5 is triangle frame, and two steel stair supports 5 are placed through tie-beam connection, two steel stair supports 5 parallel
Two cant beams between be equipped with a swash plate 4, being erect on the swash plate 4 has polylith to be used for step plate riser 1, positioned at step plate riser
The swash plate in 1 front is provided with a through hole 7, and the step plate riser 1 is provided with a bolt hole 6, a structure of an essay for through hole 7 and bolt hole 6
Provided with a stay bolt 3, the stay bolt 3 is at a right angle with swash plate 4, and one is formed between every piece of step plate riser 1 and swash plate 4 and is used to pour
The space groove of concrete 2 is filled, fill concrete 2 in the space groove, rubber antiskid layer 8 is equipped with positioned at concrete upper surface.
The steel construction cast-in-place concrete stair design structure is simple, and step plate riser is mashed up with concrete, plays reinforcement cast-in-place concrete
The bearing capacity marked time greatly improved afterwards, moreover it is possible to play a part of antidetonation noise reduction to entirely marking time, the laying of concrete upper surface
There are rubber antiskid layer, good antiskid effect, the steel construction cast-in-place concrete stair is so designed that safety coefficient height, and stability is good, the longevity
Life length.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
