Abstract
A kind of mechanical package formula precast rc slab formula stair provided by the utility model, belong to assembled architecture technical field, including precast stair main body and choose ear two parts, the precast stair main body is integrally formed by both ends platform and middle part bench, the close stairwell side of one end platform for choosing ear and precast stair main body or both ends platform is detachably connected, it platform interior and chooses the ear place of being detachably connected and is provided with built-in fitting, choose ear and be internally provided with the connector to match with the built-in fitting.The upper left type, upper right type precast stair and the precast stair main body without the total 4 kinds of different models of upper left type, upper right type precast stair for choosing ear that the utility model can make band choose ear share one set of die, to reduce mould-type, mold space is saved, cost is reduced.
Description
Technical field
The utility model belongs to assembled architecture technical field, and in particular to a kind of mechanical package formula prefabricated reinforced concrete
Cranked slab stairs.
Background technology
It is precast rc slab with widest form currently, applied to the precast stair in assembled architecture
Formula stair (hereinafter referred to as precast stair).At this stage, the precast stair type kind of different engineerings is different, same engineering
It will appear various types of precast stairs, conventional scissors ladder, double race stair etc. there is also positive and negative stair, lead to precast stair
Mold type is various, and the number of turnover is few, has increased considerably the cost of prefabricated components.
The structure of existing precast stair is as shown in Figure 1, include by both ends platform (12-1,12-2) and middle part bench 12-3 structures
At precast stair main body 12 and positioned at the side of the precast stair main body, platform chooses ear 11 close to what stairwell side was arranged；
Traditional precast stair is chosen ear 11 and is molded with 12 one-time-concreting of precast stair main body, and mostly use formwork erection in process of manufacture
Production, i.e., side where choosing ear is as cast top surface.To upper right type stair 1, (relative to people's walking position upstairs, stair shaft is in stair
The left side, that is, choose ear on the left side of stair) (such as Fig. 1 (a) shown in) and upper left type stair 2 are (terraced relative to people's walking position upstairs
Well chooses ear on the right of stair on the right of stair) (shown in such as Fig. 1 (b)), it is necessary to mating 2 kinds of precast stair molds；When not
The precast stair that setting is chosen ear and is only made of precast stair main body is needed to need to match to upper left type stair and upper right type stair
Cover other 2 kinds of precast stair molds.
Utility model content
The utility model provides a kind of mechanical package formula precast rc slab formula building for the purpose of solving the above problems
Ladder, the stair can make band choose the upper left type of ear, upper right type precast stair, total without upper left type, the upper right type precast stair for choosing ear
The precast stair main body of 4 kinds of different models of meter shares one set of die reduces cost to reduce mould-type.
The utility model proposes a kind of mechanical package formula precast rc slab formula stair, including precast stair main body
With choose ear two parts, the precast stair main body is integrally formed by both ends platform and middle part bench, which is characterized in that described to choose ear
Be detachably connected with one end platform of precast stair main body or the close stairwell side of both ends platform, platform interior and choose ear can
It is provided with built-in fitting at dismantling connection, chooses ear and is internally provided with the connector to match with the built-in fitting.
Compared with prior art, the utility model has the beneficial effects that：
By choosing being detachably connected for ear and precast stair main body, 4 kinds of model stair share one set of die, it is possible to reduce mould
Has processing capacity, while the mold of this kind of form can be saved and make mold materials dosage；The stairway die process-cycle can be shortened, choose ear
Mold has the general possibility on various criterion model component；Both ends platform reinforcing bar length is consistent, reduces scale blanking procedure, letter
Change precast stair production process；It chooses ear portions and reinforcing bar tailing can be used, realize resource-effective utilization.The application of the utility model,
Process can be simplified, mold space is saved, reduce mold type, reduce cost.
Description of the drawings
Fig. 1 is the precast stair floor map that existing band chooses ear；Wherein, Fig. 1 (a) is upper right type precast stair, Fig. 1
(b) it is upper left type precast stair.
Fig. 2 is the utility model precast stair floor map.
Fig. 3 is that ear and main body connection diagram are chosen in the utility model precast stair.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is further described in detail the utility model, but the utility model is protected
Shield content is not limited to the embodiment：
The utility model proposes a kind of mechanical package formula precast rc slab formula stair floor map such as Fig. 2 institutes
Show, now illustrated by taking upper right type stair as an example, the combination of upper left type stair is same.The upper right type precast stair by
Ear 11 and 12 two parts of precast stair main body composition are chosen, precast stair main body is by both ends platform (12-1,12-2) and middle part bench
12-3 is integrally formed, and the close stairwell side a of one end platform or both ends platform of choosing ear 11 and precast stair main body is detachable
Connection；It platform interior and chooses the ear place of being detachably connected and is provided with built-in fitting 13, choose ear and be internally provided with and match with built-in fitting 13
Connector 14 chooses the close building that ear 11 is fixed on 12 cuddy board of precast stair main body by the built-in fitting 13 and connector 14
Stair shaft side a.
After fractionation, chosen used by the upper right type and upper left type precast stair of the utility model ear can sharing die, and
It is smaller with respect to precast stair main body and other prefabricated components to choose the rebar sizes being arranged inside ear, usable precast stair main body or
The reinforcing bar tailing of other prefabricated components makes.In addition, the ear of choosing can be also combined with the precast stair main body of other sizes
Constitute different precast stairs, it is only necessary to ensure that these precast stair main bodys have the cuddy board of equal length and thickness,
To meet the needs of sizes stair.
Similar, precast stair main body can share one used by the upper right type and upper left type precast stair of the utility model
Mold, and mold bottom surface is tablet, it is easy to operate during casting concrete, and mould processing technology can be simplified, reduce mould
Tool processing former material usage amount.The mold also may be directly applied to the precast stair for being not provided with choosing ear.
Various ways can be used in the stair main body of this precast stair and the connection chosen between ear, are not limited to connect by bolt
It connects, is welded by weldable materials such as pre-embedded steel slabs, or connected by tenon structure.In the present embodiment precast stair main body 12
Built-in fitting 13 be embedded nut, it is bolt to choose the connector 14 that the inside of ear 11 is arranged, and ear will be chosen by embedded nut and bolt
Mounted on precast stair main body close to stairwell side a, it is whole to form prefabricated building body.The present embodiment precast stair is given birth to using formwork erection
Production, precast stair main body and the specific installation process for choosing ear are as follows：At the surface of precast stair body end platform junction
It manage-chooses ear and is connect with the bolt of precast stair body end platform and choose the reserved bolt hole of ear and block-choose ear and prefabricated building
The piece processing of phosphor bodies cuddy board-precast stair splicing is completed.
