Description
Technical field
This utility model belongs to cantilever stair technical field, particularly relates to a kind of staggered form cantilever stair.
Background technology
At present, " cantilever stair " is to link one of usual form between building floor.Also referred to as overlap stair,
Intersection stair or set ladder.It arranges a pair two overlapped, the most not connected stair at same staircase.At its staircase
Bench be generally single flight vertical ladder section.The most important feature of cantilever stair is, is provided with two stair in same staircase, tool
There is the function of two vertical direction fire escapes.
Common assembled cantilever stair is to be prefabricated in the factory to form, owing to for single large-scale component, its weight is 3.8 tons
To 5.5 tons, even there is heavier shears ladder, producing, transport, lifting in installation process, owing to weight is the heaviest, common crane
Or vertical hoisting equipment cannot lift by crane；Owing to single member profile size is big, position, installation position is narrow and small, installs extremely difficult；
Sectional dimension of members is little, and profile length-width ratio is excessive, and during lifting, crackle easily occurs in component.
Utility model content
Lifting and installation difficulty, sectional dimension of members is there is in this utility model for solving existing assembled cantilever stair
Little, profile length-width ratio is excessive, and during lifting, component easily occurs that the technical problem of crackle provides a kind of simple in construction, installs and uses
Convenient, the staggered form cantilever stair of raising work efficiency.
This utility model is adopted the technical scheme that by solving technical problem present in known technology:
Staggered form cantilever stair of the present utility model, described staggered form cantilever stair is provided with staggered form cantilever stair originally
Body, upper ladder beam, descending stair beam, the centre position of described upper ladder beam and descending stair beam is provided with middle ladder beam, and the two ends of middle ladder beam embed existing
Water body of wall position；Described staggered form cantilever stair body is provided with the stair of multiple intersection.
Further, the side of described stair is provided with suspension centre emaciated face mould and adjusts part.
Further, the terraced step face of described stair is arranged plane and adjust part and installing hole.
Further, described middle ladder beam is arranged on the crossover location of stair.
Further, linked together with stair by three reinforcing bars between described upper ladder beam and descending stair beam.
This utility model has the advantage that with good effect: owing to existing single cantilever stair is divided by this utility model
Become two sections, decrease the ratio of reinforcement of former bench simultaneously and reduce the thickness of former stair, to alleviate single bench weight and volume；?
On the basis of original two stair beams, ladder beam in is set at the crossover location of cantilever stair again and (i.e. forms upper, middle and lower
Three terraced beams), the profile of middle ladder beam is Chinese character pin-shaped；The reinforcing bar three of 22 is reserved with precast stair in the position that each ladder beam contacts
Root；Reserved three corresponding installing holes on precast stair；Two demoulding suspension centres are set in the side of stair, ladder step face sets
Put 4 installation suspension centres, reduce the hoisting difficulty of staggered form cantilever stair, improve the efficiency of installation.

Fig. 2 is that the emaciated face mould that this utility model embodiment provides adjusts part structural representation；
Fig. 3 is installing hole and the plane tune part structural representation of this utility model embodiment offer；
In figure: 1, staggered form cantilever stair body；2, upper ladder beam；3, descending stair beam；4, middle ladder beam；5, stair；5-1, emaciated face
Mould adjusts part；5-2, installing hole；5-3, plane adjust part.
Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows.
Below in conjunction with the accompanying drawings structure of the present utility model is explained in detail.
As it is shown in figure 1, the staggered form cantilever stair of this utility model embodiment includes: staggered form cantilever stair body 1, on
Ladder beam 2, descending stair beam 3, middle ladder beam 4, stair 5.
Staggered form cantilever stair body 1 is provided with ladder beam 2 and descending stair beam 3, and middle ladder beam 4 is arranged on ladder beam 2 and descending stair
The centre position (crossover locations of stair 5) of beam 3, is connected to stair 5 by three reinforcing bars between upper ladder beam 2 and descending stair beam 3
Together, the two ends of middle ladder beam 4 should embed cast-in-situ wall position and should arrange sleeper or reinforcing bar encryption.
As shown in Figures 2 and 3, the side of stair 5 arranges the suspension centre emaciated face mould tune part 5-1 of two demouldings, the ladder of stair 5
4 planes installed are set on step face and adjust part 5-2, the terraced step face of stair 5 arranges the installing hole 5-corresponding with three reinforcing bars
2。
Operation principle of the present utility model:
Existing single cantilever stair is divided into two sections by this utility model, reduces the ratio of reinforcement of former bench simultaneously and reduces former
The thickness of stair, to alleviate single bench weight and volume；On the basis of original two stair beams, in the friendship of cantilever stair
Fork position arranges ladder beam in (i.e. forming three terraced beams of upper, middle and lower) again, and the profile of middle ladder beam is Chinese character pin-shaped；At each ladder
The reinforcing bar three of 22 is reserved in the position that beam contacts with precast stair；Reserved three corresponding installing holes on precast stair；At stair
Side two demoulding suspension centres are set, ladder step face arranges 4 installation suspension centres.
The above is only to preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modify, belong in the range of technical solutions of the utility model.
