Description
Technical field
The present invention relates to a kind of stair method for prefabricating, the prefabricated profiled stair of this method are mainly used for assembled architecture.
Background technology
With the development of modern industrial technology, building house can be manufactured in batch completely as machine production.As long as
Prefabricated house component, transport to assemble in site and get up just into i.e. assembled architecture.Assembled architecture refers to prefabricated
The building that component is formed in assemble in site.This building has the characteristics that：
1. substantial amounts of building subassembly is machined by Workshop Production, component species mainly has:Side fascia, lining, overlapping
Plate, balcony, air-conditioning plate, stair, precast beam, prefabricated post etc..
2. the substantial amounts of assembling work in scene, greatly reduces than original cast-in-place operation.
3. using building, finishing integrated design, construction, perfect condition is that finishing can synchronously be carried out with main body construction.
4. the informationization of standardization and the management of design, component get over standard, production efficiency is higher, and corresponding component cost is just
It can decline, coordinate the digital management of factory, the cost performance of whole assembled architecture can be higher and higher.
5. meet the requirement of green building.
Stair are as one of component more important in assembled architecture, with layer function above and below connection, therefore to stair
Method for prefabricating research is of great significance.
The content of the invention
Present invention purpose in this is to provide a kind of stair method for prefabricating, and the prefabricated profiled stair of this method are ensureing building
The lighter in weight of stair while terraced load-bearing capacity.
To achieve the object of the present invention, the stair method for prefabricating provided realizes stair using reinforced concrete mating mold
It is prefabricated, for assembled architecture, which comprises the following steps that：
S1：Rule in stairway die, indicate the region for laying lightweight module, and by prefabricated profiled lightweight mould
Block is laid in region；
S2：Reinforcing bar is laid around lightweight module, the reinforcing bar extends stairway die along stairway die length direction；Institute
State and gap is left between reinforcing bar and the region for laying lightweight module, or the reinforcing bar is used to lay lightweight with described
The outer surface contact in the region of module；
S3：The casting concrete into stairway die, makes concrete fill up whole stairway die；
S4：Stand, stand 12~24h, treat that stair are molded；
S5：Molding stair are taken out, dry shaping.
This method indicates the region for laying lightweight module in advance, and lightweight module is laid in region, and gently
Reinforcing bar is laid around matter module, finally casting concrete again.First lay lightweight module and reinforcing bar, after-pouring concrete.By mixed
Interval between solidifying soil light filling module, between lightweight module and reinforcing bar and between reinforcing bar, and be placed in stairway die
Reinforcing bar and lightweight module are coated by concrete, and the ability of weighing of stair, lightweight are ensure that under the action of reinforcing bar and concrete
Module is filled in stair, reduces the dosage of concrete, reduces the weight of stair.
Specifically, when carrying out step S3, stairway die is swung.During casting concrete, swinging stairway die makes concrete
Filling evenly, more fully, efficiently avoid the situation for occurring cavity in stair.
Specifically, described in step S1 be used to lay and leave between the region of lightweight module and stairway die inner wall between
Every.The interval between region and stairway die inner wall can be filled in concreting process, so that by lightweight module
All it is coated in concrete, has not only protected lightweight module, but also prevent the landing of lightweight module.
Specifically, the region for being used to lay lightweight module described in step S1 is at least one layer, every layer include one or
More sub-regions；It is spaced and lays between more sub-regions.
The beneficial effects of the invention are as follows：By between Concrete Filled lightweight module, between lightweight module and reinforcing bar and
Interval between reinforcing bar, and the reinforcing bar and lightweight module that are placed in stairway die are coated by concrete, in reinforcing bar and concrete
Under the action of ensure that the abilities of weighing of stair, lightweight module is filled in stair, reduces the dosage of concrete, reduce building
The weight of ladder.It efficiently avoid the situation for occurring cavity in stair.

Embodiment
Claimed technical solution of the invention is described in further detail with reference to attached drawing herein.
As shown in Figure 1,2 and 3, claimed technical solution of the invention is a kind of method for prefabricating of stair, this method
The prefabricated of stair is realized using reinforced concrete mating mold, for assembled architecture.Realized using existing stairway die, tool
Body step is as follows：
S1：Rule in stairway die 1, indicate the region 2 for laying lightweight module, and by prefabricated profiled lightweight
Module is laid in region 2；
S2：Reinforcing bar is laid, reinforcing bar 3 is laid around lightweight module, reinforcing bar 3 extends along the length direction of stairway die 1
Stairway die 1, the end cap 11 at corresponding 1 both ends of stairway die, which is equipped with, is used for the through hole that reinforcing bar 3 passes through；Extend stairway die
1 reinforcing bar 3 is connecting pin, due to being connected with other components, such as wall, and another stair.Reinforcing bar 3 lays lightweight module with being used for
The interval 4 of 5cm, 8cm or 13cm can be left between region 2, can not also be stayed, reinforcing bar 3 is laid lightweight module with being used for
Region 2 outer surface contact；
S3：The concrete being stirred is poured into stairway die 1 from top to bottom, concrete is filled up whole stairway die 1,
Fill up interval 4 at the same time；
S4：Stand, after concrete fills up stairway die 1, stop pouring, stand a period of time, such as 12h, 18h, or
24h, treats that stair are molded；
S5：Molding stair are taken out, dry shaping.
In order to enable the concrete poured to fill up whole stairway die 1, hollow situation is avoided the occurrence of, in casting concrete
During swing stairway die 1, make the Concrete Filled poured evenly.
In order to enable the concrete poured all to coat lightweight module, avoid lightweight module from being exposed in air, prevent
Only it slides, and when being indicated to region 2, is left between the left and right inner wall of region 2 and stairway die 1, upper and lower inner wall
6cm, 10cm or 15cm interval.Therefore step S1 can also be in the above method：A layer concrete first is poured to stairway die 1,
The bottom 12 of stairway die 1 is pre-formed a layer concrete, realize the interval between 1 bottom inner wall of region 2 and stairway die,
Then rule again in stairway die 1, indicate the region 2 for laying lightweight module, and by prefabricated profiled lightweight module
It is laid in region 2.Region 2 only need to be from having interval between 1 or so inner wall of stairway die, the height of the lightweight module of placement is small
It can be achieved that there is interval between region 2 and 1 or so inner wall of stairway die and upper inner wall in the height of stairway die 1.
The region for being used to lay lightweight module in sign is at least one layer, and every layer includes one or more subregions；It is multiple
3cm, 7cm or 10cm is spaced between subregion to lay.
The stair of any type structure can be prefabricated into using above method, as band marks time 5, without marking time 5；Band rest ledge
6, without rest ledge 6.
The lightweight module laid in region 2 can be gypsum module, foam concrete module, haydite concrete module,
Air entrained concrete module or EPS modules.It is pre-formed, is directly laid in region 2.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, those of ordinary skill in the art are to this hair
The modification or equivalent substitution that bright technical solution is made, without departing from the spirit and scope of technical scheme, contain
Cover in scope of the presently claimed invention.
