Description
【Technical field】
The utility model is related to a kind of building elements, and in particular to a kind of lightweight assembled stair belong to assembled architecture
Component technology field.
【Background technology】
Stair are one of indispensable facilities in building.The stair of the prior art are often through cast-in-place mode-field
It makes, i.e., by template built, wiretie is poured to be formed with cement mortar again, often low there is structural strength, it is impossible to
Realize prefabricated, and own wt weight, many defects such as of high cost.
Therefore, in order to solve the above technical problems, a kind of lightweight assembled stair it is necessory to provide innovation, existing to overcome
There is the defect in technology.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide a kind of simple in structure, light weights, at low cost and just
In the lightweight assembled stair that high-volume is prefabricated.
To achieve the above object, the technical solution that the utility model is taken is：A kind of lightweight assembled stair, including extremely
The transversary beam that few twice main body cant beam connects main body cant beam at least 2, in being provided with several on the main body cant beam
Rank；It is gone along with sb. to guard him using expanded metal lath the bottom of the main body cant beam；It is filled in the cavity that the main body cant beam, step and expanded metal lath surround
There is lightweight concrete layer.
The lightweight assembled stair of the utility model are further arranged to：The expanded metal lath can be replaced by sieve.
The lightweight assembled stair of the utility model are further arranged to：The step is concrete prefabricated step, and by
Expanded metal lath exempts to tear open for bed die to be poured, and wall thickness is 30~50mm.
The lightweight assembled stair of the utility model are further arranged to：The both ends of the main body cant beam are equipped with and mark time, institute
It states main body cant beam and marks time as integrated precast structure.
The lightweight assembled stair of the utility model are further arranged to：The lightweight concrete layer can be by modified polyphenyl
The mixture of grain and light concrete substitutes.
The lightweight assembled stair of the utility model are further arranged to：The outer surface of the expanded metal lath is equipped with a decorative cover
Layer.
The lightweight assembled stair of the utility model are further arranged to：The cavity by the bottom of the steps triangular cavity
Cavity composition between adjacent body cant beam.
The lightweight assembled stair of the utility model are further arranged to：The main body cant beam is prefabricated for armored concrete
Beam is obliquely installed in 30~60 °.
The lightweight assembled stair of the utility model are also configured to：The main body cant beam is specifically provided with three.
Compared with prior art, the utility model has the advantages that：
1. the lightweight assembled stair of the utility model are in non-weight bearing area light filling concrete, so as to significantly reduce
The weight of stair, and the cracking resistance of external impact force can be resisted
2. large-scale industrialized prefabricated, the shortening architecture construction time can be used in the lightweight assembled stair of the utility model,
And convenient for batch production
3. the lightweight assembled stair sound construction of the utility model, good appearance are at low cost.
【Description of the drawings】
Fig. 1 is the sectional view of the lightweight assembled stair of the utility model.
Fig. 2 is that the lightweight assembled stair of the utility model are not filled by the schematic diagram of lightweight concrete.
Fig. 3 is that the lightweight assembled stair of the utility model are not filled by the sectional view of lightweight concrete (along main body cant beam side
To).
Fig. 4 is the bottom view of the lightweight assembled stair of the utility model.
【Specific embodiment】
It please refers to shown in Figure of description 1 to attached drawing 4, the utility model is a kind of lightweight assembled stair, including extremely
The transversary beam 8 that few twice main body cant beam 1 connects main body cant beam 1 at least 2.In the present embodiment, the main body is oblique
Beam 1 is specifically provided with three, is armored concrete precast beam, is obliquely installed in 30~60 °.The two of the main body cant beam 1
End is equipped with and marks time 6, the main body cant beam 1 and marks time 6 as integrated precast structure.
In being provided with several steps 2 on the main body cant beam 1.The step 2 is concrete prefabricated step, and by expanded metal lath
3 exempt to tear open and pour for bed die, and wall thickness is 30~50mm.All steel is formed by main body cant beam 1, transversary beam 8 and step 2
Concrete structure " rectangle trellis " stair.
It is gone along with sb. to guard him using expanded metal lath 3 bottom of the main body cant beam 1.The expanded metal lath 3 can also be substituted by sieve.Further
, the expanded metal lath 3 can serve as template use, and be connected with main body cant beam 1, can realize " bottom filling " moulding by casting.The steel
The outer surface of expanded metals 3 is equipped with an architectural surface (not shown).
Lightweight is filled in the cavity 4 (i.e. non bearing structure space) that the main body cant beam 1, step 2 and expanded metal lath 3 surround
Concrete layer 5 with the self-strength of lightweight concrete, after filling calculates the non-bearing space obtained, realizes prefabricated components
Appearance and functional use.The cavity 4 is by the cavity groups between the triangular cavity of 2 bottom of step and adjacent body cant beam 1
Into.The lightweight concrete layer 5 can be substituted by the mixture of modified polyphenyl particle and light concrete.
The lightweight assembled stair of the utility model are made using following construction method：
1), prefabricated at least twice main body cant beam 1；And prefabricated several grades of steps 2.
2), step is placed on main body cant beam 1.
3), in the bottom supporting expanded metal lath 3 or sieve of main body cant beam 1.
4), lightweight concrete 5 is filled in the cavity surrounded by main body cant beam 1, step 2 and expanded metal lath 3；Expanded metal lath 3
The lightweight concrete of package can resist the cracking resistance of external impact force, and be existed using expanded metal lath 3 in different materials compound tense
The cushioning effect of shrinking percentage difference is played in certain section.
5), in expanded metal lath 3 or one layer of architectural surface of appearance surface construction of sieve, so as to make the appearance looks elegant of stair.
Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection domain it
It is interior.
