Description
Technical field
The utility model relates to a kind of technical field of building structure, is specially a kind of separate type precast hollow landing.
Background technology
For a long time, the building industry labor productivity ratio of China is low, has a strong impact on and constrain the fast development of Building Trade in China.Mainly because Building Trade in China field fabrication, wet trade etc. are many, cause that many, the artificial demands of waste of material are many, construction cost is high, long construction period etc.Along with I crosses the development of market economy, the name of " housing industrialization " is fade-in ear curtain, and fast-developing, and the development of prefabrication becomes development trend gradually.Stair, as one of structural element very important in Residential structure, play an important role in the process promoting housing industrialization.In traditional architectural stair structure, the fabrication and installation of landing mainly contain: make with the overall cast in situs of stair tread, have from great, complicated construction technique, speed of application is slow, the cycle is long and high cost shortcoming; With the overall prefabrication of stair tread, have volume large, from great, make shortcomings such as requiring high and hoisting transportation inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of precast stair platform from heavy and light, easily installation is provided, and can be used as construction control platform when main structure construction, with agent structure monobloc cast, facilitate engineering construction, accelerate speed of application, shorten whole construction period, greatly improve efficiency of construction, promote the development of architectural industrialization, meet the architectural industrialization policy that current country advocates.
The technical solution of the utility model is:
A kind of separate type precast stair platform, comprise landing slab and landing beam, it is characterized in that, described landing slab and landing beam are integral prefabricated form, in landing slab and landing beam, be provided with starter bar, this starter bar is used for and being fixedly connected with of agent structure; Described landing beam is provided with stair tread mounting groove, and described mounting groove is provided with pre-buried pressure-bearing steel plate.
Feature of the present utility model also has:
Wherein, described mounting groove is " L " type mounting groove, for overlapping precast stair plate, and described landing plate and platform is beam prefabricated is integrated.
The size of mounting groove can be 100x180mm or 120x210mm etc.
Longitudinal loss of weight through hole is provided with in landing beam.
Lightening hole is provided with in landing slab; Lightening hole in described landing slab is parallel with the loss of weight through hole of landing beam or vertically arrange.
The cross sectional shape of described lightening hole or loss of weight through hole can be circle or hexagon or octagon.
The beneficial effects of the utility model are:
Compared with prior art, this landing is separate type precast stair component, is hollow-core construction, conducts oneself with dignity little, the planform of mounting groove is " L " shape, mounting groove opening size is according to concrete actual design, can flexible design, landing starter bar, realize being connected with the effective of agent structure, in a word, the utility model landing is Prefabrication in factory, overcome landing and the cast-in-place making of agent structure in the past, complicated construction technique, the shortcomings such as long construction period, overcome precast stair platform and stair tread in the past integral prefabricated, volume is large, weight is large, making requires high, the defects such as transporting and hoisting difficulty, there is convenient construction, construction quality easily ensures, speed of application is fast, short construction period, reduce the advantages such as construction costs.

Wherein, described mounting groove is " L " type mounting groove, and for overlapping precast stair plate, described landing plate and platform is beam prefabricated is integrated, the size of mounting groove can be 100x180mm.
Longitudinal loss of weight through hole 4 is provided with in landing beam 2.
Lightening hole 6 is provided with in landing slab 1; Lightening hole 6 in described landing slab be arranged in parallel with the loss of weight through hole 4 of landing beam.
Described lightening hole 6 or the cross sectional shape of loss of weight through hole 4 can be circle.
Three limits of described landing plate 1 are provided with starter bar 3; The two ends of described precast stair landing beam are reserved with overlap joint reinforcing bar 3; Described precast stair platform Prefabrication in factory.
This landing is rectangular configuration form, and size, according to the design stair standard width of a room in an old-style house, longly can be 2.4m, 2.7m, 3.0m equidimension, widely can be 0.9m, 1.2m, 1.8m equidimension, meets the modulus requirement of building 3M.
embodiment 2
The size of mounting groove can be 120x210mm etc.
Loss of weight through hole 4 or lightening hole 6 are hexagon.
