It is excessive, waste of material is serious, be unfavorable for marketing while transporting and hoisting be also relatively difficult.
Utility model content
The purpose of this utility model is to solve the defects of above-mentioned existing, there is provided a kind of low cost, be easily installed and
The hollow stair of marking time of the precast concrete of transport.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of hollow stair of marking time of precast concrete, including landing, precast stair plate and be located on precast stair plate
Stair step, the landing, which includes going upstairs, platform and goes downstairs platform, is poured into a mould in one end of the platform of going upstairs
There is upper strata crossbeam, lower floor's crossbeam is cast with one end of the platform of going downstairs, the precast stair plate rides upon upper strata crossbeam
With between lower floor crossbeam, the stair step is located on precast stair plate, it is characterised in that：Also include loss of weight tube filler and node is consolidated
Determine part, the loss of weight tube filler is laterally located in stair step, is vertically lifted at interval of being equipped with 1 in 4~6 section stair steps
Hole, the vertical hole for hoist that reinforcing bar is worn in stair step are fixed with precast stair plate, in inserting for reinforcing bar and the vertical hole for hoist
Gap filling adhesive is connect, the node fixture is respectively provided at connection end and the lower floor's horizontal stroke of upper strata crossbeam and precast stair plate
The connection end of beam and precast stair plate, the node fixture are made up of cross loop bar and anticreep ring set, the cross loop bar
One end is installed in upper strata crossbeam or lower floor's crossbeam, one end grafting of the other end and precast stair plate, the anticreep ring set difference
It is arranged the connection end of upper strata crossbeam and precast stair plate and the connection end of lower floor's crossbeam and precast stair plate, the precast stair
The connection end end face of plate and upper strata crossbeam is provided with buffer gap, and fastening block is provided with the buffer gap.
As preferable technical scheme, the section of the loss of weight tube filler is hexagonal cross-section, in the internal face of loss of weight tube filler
Provided with waterproof coating.
The beneficial effects of the utility model are：Concrete consumption can be reduced, the deadweight of staircase boards is reduced, is readily transported and shows
Field construction, cost is relatively low, is advantageous to marketing.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the hollow stair of marking time of precast concrete of the utility model；
In figure：1- landings, 1-1- go downstairs platform, 2- precast stairs plate, 3- stair of platform, 1-2- of going upstairs are stepped on
Step, 4- upper stratas crossbeam, 5- lower floors crossbeam, 6- losss of weight tube filler, the vertical holes for hoist of 7-, 8- nodes fixture, 8-1- crosses loop bar,
