Description
Technical field
It the utility model is related to building field, more particularly to the stair of armored concrete and steel construction.
Background technology
State Council prints and distributes《On greatly developing the instruction of assembled architecture》（The Office of the State Council sends out { 2016 } No. 71）, determine big
Power develops assembled architecture, promotes construction industry industry restructuring upgrading.According to propulsion supply side structural reform and new city
The requirement of townization development, greatly develops steel construction assembled architecture（PS）, concrete assembled building（PC）Deng with development section
Can environmentally friendly NPD projects, raising building safety level, the effect for promoting neutralizing superfluous production capacity etc. to achieve many things at one stroke.It is prefabricated assembling type reinforced mixed
Xtah Crude Clay structure builds the mainstream technology as existing market, component, part standard design, factorial praluction, assembling or machine
Toolization is constructed；It is general to be designed by a full set of architectural drawing, it is good prefabricated in plant produced after carrying out Deepen Design to structural working drawing
The PC components such as the beam of concrete, column, wall, plate, stair, transport to scene and carry out prefabricated construction.
And deficiency existing for current building cantilever stair is, due to being directly integrally formed, and the pin in factory
It is more than 5 meters of stair to part ladder length, general weight all can be more than 5 tons, so production can be given（It is prefabricated）, transport, hang
Dress, installation, construction increase difficulty, it is understood that there may be security risk；Particularly lift and install, the lifting of the bigger requirement of stair weight
Equipment tonnage is higher, corresponding production（It is prefabricated）, transport, lifting, installation, construction etc. cost it is higher.
The content of the invention
In order to overcome the above problem, the utility model, which provides one kind, can reduce lifting and installation cost and easy to produce（In advance
System）, transport, construction segmented staircase structure.
To achieve the above object, the technical solution of the utility model offer is：
A kind of building cantilever stair of block assembly type, including in same layer be equipped with to the straight stair one to uplink,
Stair two, and the floor height of same layer stair one, stair two is 2.8-5.6m；The stair one, stair two are mutually arranged in a crossed manner,
Stair one are provided with bench（10）、（11）, stair two are equipped with bench（20）、（21）, in stair one and two place plane of stair
Intersecting lens is provided with support beam, is provided with two supporting surfaces in support beam, two supporting surfaces respectively with stair one, stair two
Abut so that support beam meets bearing width with stair one, the overlapping area of stair two.
The support beam, which includes a left side, to be widened and is widened with the right side, and the left side is widened to abut with stair one, the right side
Widen and abutted with stair two.
The left expanded width of the support beam extends to bench for support beam width（10）Stair harden structure under
Edge, the right expanded width of the support beam extend to bench for support beam width（20）Stair harden structure it is following
Edge.
The left expanded width of the support beam is identical with right expanded width.
Above-mentioned technical proposal is beneficial in that：
1st, the utility model provides a kind of building cantilever stair of block assembly type, is handed over using staircase boards segmentation in cantilever stair
Crunode increase support beam, which reaches, mitigates staircase boards length and weight, is producing（It is prefabricated）When both can be by a part of stair gangboard
It is separated into two sections of productions（It is prefabricated）, transport, lifting, installation, construction, flight staircases plate can have both been overcome because stair length is too long,
Production caused by weight is too big, transport, lifting, installation, the problems such as difficulty of construction is big, of high cost, while staircase boards overlap joint and
The thickness of cross beam support junction, can ensure that the vertical height of stair harden structure lower edge to walkway is not less than the state of 2.000m
Family's specification regulation requires, and during normal use meeting national regulation will using size as defined in function stair to different buildings
Ask.
2nd, the segmented staircase structure of the utility model, widens extension and the setting on inclined-plane by support beam, can improve horizontal stroke
Beam and the intersubjective contact area of hypomere, then improve stable connection, and the bearing value of crossbeam.
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, ordinary skill
Personnel's all other embodiments obtained without making creative work, belong to the scope of the utility model protection.

Embodiment
Embodiment 1
A kind of building cantilever stair of block assembly type, including in same layer be equipped with to the straight stair 1 to uplink,
Stair 22, and the floor height of same layer stair 1, stair 22 is 2.8-5.6m；The stair 1, stair 22 intersect
Set, stair one are provided with bench（10）、（11）, stair two are equipped with bench（20）、（21）, where stair 1 and stair 22
The intersecting lens of plane is provided with support beam 4, is provided with two supporting surfaces in support beam 4, two supporting surfaces respectively with bench
（10）, bench（20）Abut so that support beam 4 and bench（10）, bench（20）Contact area meet bearing width.
Setting in this way, supports stair main body using support beam, is producing（It is prefabricated）When can be by stair
Main body is separated into two sections of productions（It is prefabricated）, segmented stair can both overcome the prior art to pacify caused by stair size is too big
The problems such as difficulty is big, installation cost is high is filled, while institute's increase stair main body and the thickness of crossbeam junction can meet levels
The vertical height of stair harden structure lower edge to walkway meets not less than 2.000m and same race stair step width and height
National regulation uses different buildings size requirement as defined in function stair.
Required according to current national codes, be guarantor travel height for upper and lower floor gangboard structure lower edge to people
The vertical height of row of channels is not less than the limitation of 2.000m, and the utility model is by the setting of crossbeam and crossbeam local widening, can be real
It is existing easy to produce（It is prefabricated）, transport, lifting, installation, construction purpose on the premise of, still ensure that upper and lower floor gangboard structure
The vertical height of lower edge to walkway meets the requirement of national regulation regulation, while has the wide enough bearing for meeting each bench
Stress acts on.
Specifically, the support beam 4 include a left side widen 40 and the right side widen 41,40 and bench are widened in the left side
（10）Abut, 41 and bench are widened in the right side（20）Abut.
Specifically, 40 width are widened on a left side for the support beam 4 extends to bench for 4 width of support beam（10）Building
Gangboard structure lower edge, the right side of the support beam 4 widen 41 width and extend to bench for 4 width of support beam（20）Building
Gangboard structure lower edge.
More specifically, the left expanded width 40 and right expanded width 41 are provided with inclined-plane 43, the energy of inclined-plane 43 and bench
（10）, bench（20）Bottom surface coincide；Setting in this way, can improve the contact area of crossbeam and staircase, then carry
High stable connection.
Preferably, the left expanded width 40 of the support beam 4 is identical with right expanded width 41, and left expanded width 40
It is identical with the inclined-plane 43 of right expanded width 41.
As shown in Fig. 1,4, the inclined-plane 43 of the support beam 4 is directed towards bench（10）、（20）Lower end set, this
Sample may insure that the inclined-plane of extension section can be with bench（10）、（20）The bevel edge of bottom coincide, and further improves support beam
Supporting role.
