Description
Technical field
The utility model is related to buildings in general, specially a kind of mixed structure precast stair.
Background technology
Because cast-in-site stair have more deficiency, therefore, this area provided a variety of industrial in factory in recent years
Change the technical scheme for making stair product, used to be directly installed on building.But this stair are at present not yet by this
Field approve, itself main reason is that：Pre- stair weight is larger, and handling and installation are complicated, make the production cost of precast stair
It is higher than cast stair.Although the advantage of precast stair is a lot, is loaded and unloaded because it is present, complicated deficiency is installed, made existing pre-
Stair product processed can not be promoted the use of.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of prefabricated building of the mixed structure for being easily installed and transporting
Ladder.
To solve the above problems, technical solution adopted in the utility model is：
A kind of mixed structure precast stair, its key technology is：It includes the stair supporting plate and peace of concreting
Multiple step plates in the stair supporting plate, the step plate is section wooden or lightweight steel construction strip triangular in shape
Body, step plate is bolted in the stair supporting plate, the stair supporting plate include inclined support plate body with
And it is arranged on the support plate body two ends and horizontal-extending lower carrier and upper carrier.
As further improvement of the utility model, steel pipe skeleton, the steel pipe bone are provided with the stair supporting plate
Support column and welding that frame is arranged side by side including two or more are arranged on some support beams on the support column.
As further improvement of the utility model, suspension ring are provided with the lower carrier and upper carrier.
It is using the beneficial effect produced by above-mentioned technical proposal：
The utility model sets the support plate body of stair and step plate split, and step plate using wooden structures or
Lightweight steel construction, makes simple and convenient, lighter in weight so that the structure of stair supporting plate is simpler, smooth below thereon, pours
Simplicity, it is conveniently laying in transport, occupy little space.Step plate split design can be mitigated into the weight of stair supporting plate, stepped on
Convenient concentrate of plate is walked to arrange and transport.Whole stair supporting plate greatlys save the working time when playing sling cart and lifting is installed,
Reduce working strength.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model steel pipe skeleton.
Wherein：Carrier, the upper carriers of 1-3,1-4 support columns, 1-5 under 1 stair supporting plate, 1-1 support plate bodies, 1-2
The pre-buried connecting plate B of support beam, 1-6 service sleeves, 1-7 depressed parts, 1-8 pre-buried connecting plate A, 1-9,2 step plates, 2-1 lightening holes,
3 fixing bolts, 4 suspension ring.
Embodiment
1-2 and specific embodiment are described in further detail to utility model below in conjunction with the accompanying drawings：
A kind of mixed structure precast stair as shown in Figure 1, it includes the stair supporting plate 1 of concreting and is arranged on
Multiple step plates 2 in the stair supporting plate 1, the step plate 2 is section strip shape body triangular in shape, and step plate 2 passes through
It is bolted in the stair supporting plate 1, pre-buried connecting plate A1-8 and pre-buried connecting plate is provided with the stair supporting plate 1
B1-9, the pre-buried connecting plate A1-8 is vertically arranged, and the pre-buried connecting plate B1-9 is horizontally disposed with, and the step plate 2 passes through solid
Determine bolt 3 to be connected with the pre-buried connecting plate A1-8 and pre-buried connecting plate B1-9.
The step plate 2 is provided with lightening hole 2-1 in its longitudinal direction, can substantially reduce the weight of step plate 2, drop
The heavy burden of lowrise ladder supporting plate 1, the step plate 2 is that concreting is molded or used lighter wooden structures.
The stair supporting plate 1 includes inclined support plate body 1-1 and is arranged on the support plate body 1-1 two ends
And horizontal-extending lower carrier 1-2 and upper carrier 1-3, steel pipe skeleton is provided with the stair supporting plate 1.
As shown in Fig. 2 the steel pipe skeleton include the support column 1-4 that is arranged side by side of two or more and welding be arranged on it is described
Some support beam 1-5 on support column 1-4.Described support column 1-4 and support beam 1-5 is using pipe or square tubes soldering one
Rise, form steel pipe skeleton, because steel pipe skeleton takes more space so that the unit weight reduction of stair supporting plate 1, therefore make it
Weight reduction, convenient transport and lifting are convenient to install.
Above and below the support column 1-4 is each extended in supreme carrier 1-3 and lower carrier 1-2, described steel pipe skeleton
On bar-mat reinforcement or peg can also be set, to increase the cohesive force between steel pipe skeleton and concrete structure.
Suspension ring 4 are provided with the lower carrier 1-2 and upper carrier 1-3, for lifting by crane stair supporting plate 1.It is described
Suspension ring 4 be with the built-in fitting being embedded in lower carrier 1-2 and upper carrier 1-3 to be connected through a screw thread or weld or will
The connecting portion of suspension ring is embedded in lower carrier 1-2 and upper carrier 1-3.Wherein, by being threadedly coupled with built-in fitting, conveniently tear open
Dress, suspension ring 4 can be removed when that need not lift by crane, it is to avoid it influences the flatness of stair, it is to avoid as obstacle.
Described support column 1-4 end welding is provided with the female service sleeve 1-6 of apparatus, in lower carrier 1-
Depressed part 1-7 is provided with 2 and upper carrier 1-3, depressed part 1-7 is located at service sleeve 1-6 outside, and depressed part 1-7 is filled up
Anti-corrosion material.Service sleeve is used to make lower carrier 1-2 and upper carrier 1-3 be bolted with support beam or structural slab,
Play fixation, it is to avoid activity.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still be modified to the technical scheme described in previous embodiment, or which part technical characteristic is equal
Replace；And these modifications or replacement, the essence of appropriate technical solution is departed from the utility model embodiment technical scheme
Spirit and scope.
