Description
Technical field
The utility model belongs to technical field of buildings, more particularly to a kind of Novel section steel concrete prefabricated stairs, mainly
For more high-rise assembled architectures, instead of traditional concrete prefabricated stairs.
Background technology
In more high level assembled architecture building courses, beam mainly uses concrete prefabricated stairs, mainly there is following drawback：
Drawback one：Connecting node required precision is higher, is not easy to in-site installation.
Drawback two：The connection of normal concrete precast stair is hinged, and anti-seismic performance is not strong.
Drawback three：Normal concrete precast stair pin junction does not seal, and is easy corrosion, and durability is not strong.
Invention content
The purpose of this utility model is to provide a kind of Novel section steel concrete prefabricated stairs, which has installation
It is convenient, the advantages that anti-seismic performance is good, has concrete package at connecting node, and durability is strong.
The purpose of this utility model and its technical problem underlying is solved using following technical scheme to realize：It is a kind of new
Type steel reinforced concrete precast stair, which is characterized in that including stair reinforcing bar, shaped steel, concrete staircase main body, concrete staircase master
Be distributed more stair reinforcing bars in vivo, the cant beam upper and lower end parts both sides of concrete staircase main body have been separately added into shaped steel, shaped steel with it is pre-
The built-in fitting welding of the steel frame beam or normal concrete composite beam of the steel reinforced concrete composite beam of composite beam processed.
Above-mentioned Novel section steel concrete prefabricated stairs, wherein：The upper and lower end parts of stringer are reserved with stair reinforcing bar, building
Terraced reinforcing bar anchors into the superimposed sheet of landing, and reserved stair reinforcing bar length reaches the anchorage length of shockproof requirements.
When construction, stair reinforcing bar is placed on tooling platform in factory first（Reserved protective layer）, then shaped steel be placed in
On tooling platform, then casting concrete stair main body, form Novel section steel concrete prefabricated stairs.In use, only need should
Product is lifted into the installation site in house, by shaped steel and steel reinforced concrete composite beam shaped steel or normal concrete composite beam in
Built-in fitting welding, then casting concrete wrap up connecting node.The utility model has easy for installation, and anti-seismic performance is good, connection
There is concrete package at node, the advantages that durability is strong.
The utility model has clear advantage and advantageous effect compared with prior art.By above technical scheme it is found that
The utility model has the characteristics that：
1, it solves in more high-rise assembled architectures, the drawbacks of common precast concrete stair scene is not easy to installation.Newly
For type steel reinforced concrete precast stair due to adding short steel in the end of stringer, this short steel can be folded with steel reinforced concrete
The steel frame beam of beam or the built-in fitting welding on normal concrete composite beam are closed, such type of attachment required precision is higher, Ke Yigen
It is easy for installation according to on-site actual situations adjusting position.
2, it solves the reinforcing bar in normal concrete precast stair not anchoring into inside terraced beam or gangboard, anti-seismic performance is not strong
Drawback.The reserved reinforcing bar in Novel section steel concrete prefabricated stairs end can anchor into the superimposed sheet of landing, can reach anti-
Desired anchorage length is shaken, there is preferable anti-seismic performance.
3, the not strong drawback of normal concrete precast stair junction durability is solved.The concrete prefabricated building of Novel section steel
Ladder is welded due to the short steel of cant beam end with the reinforcing bar in steel reinforced concrete ladder beam or the built-in fitting in steel reinforced concrete composite beam
It is wrapped up by cast-in-place concrete after connecing, the Anticorrosion for considering connecting node can not had to, durability is stronger.
Description of the drawings

Fig. 2 is the vertical view of Fig. 1；
It is marked in figure：1, stair reinforcing bar, 2, shaped steel, 3, concrete staircase main body, 4, built-in fitting, 5, Prefabricated superposed beam.
Specific implementation mode
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes Novel section steel concrete prefabricated stairs
Specific implementation mode, structure, feature and its effect are described in detail as after.
Referring to Fig. 1-2, a kind of Novel section steel concrete prefabricated stairs, which is characterized in that including stair reinforcing bar 1, shaped steel 2,
Concrete staircase main body 3, is distributed more stair reinforcing bars 1 in concrete staircase main body 3, above and below the cant beam of concrete staircase main body 3
End both sides have been separately added into shaped steel 2, the steel frame beam of shaped steel 2 and the steel reinforced concrete composite beam of Prefabricated superposed beam 5 or common mixed
The built-in fitting 4 of solidifying soil composite beam welds.
Above-mentioned Novel section steel concrete prefabricated stairs, wherein：The upper and lower end parts of stringer are reserved with stair reinforcing bar 1,
Stair reinforcing bar 1 anchors into the superimposed sheet of landing, and reserved 1 length of stair reinforcing bar reaches the anchorage length of shockproof requirements.
When construction, stair reinforcing bar 1 is placed on tooling platform in factory first（Reserved protective layer）, then shaped steel 2 set
In on tooling platform, then casting concrete stair main body 3, form Novel section steel concrete prefabricated stairs.In use, only need by
The product is lifted into the installation site in house, by shaped steel 2 and steel reinforced concrete composite beam shaped steel or normal concrete overlap
Built-in fitting welding in beam, then casting concrete wrap up connecting node.The utility model has easy for installation, anti-seismic performance is good,
There is concrete package at connecting node, the advantages that durability is strong.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
