Background technology
Due to being affected by limit for height, moulding etc., exist in designing at present and lead to the staircase of roofing in a large number and cannot do top cover, ladder
Directly exceedingly high, the as half-headed forestair of section.Even it is incubated to do waterproof to this kind of forestair, existing general place
Reason method is that, using the outer waterproof of painting type on the step plate of stair, waist slab bottom is incubated with thermal insulation mortar.But, due to building
The step plate turnover of ladder is more, inconvenience of not only constructing, and waterproof effect is poor；The thermal insulation mortar at plate bottom is easily peeled off, and is not only protected
Temp effect is undesirable, also there is potential safety hazard, affects the life of habitant.Therefore, existing forestair has construction not
Just the problem that, waterproof effect is poor, heat insulation effect is undesirable and safety is undesirable.
Utility model content
The purpose of this utility model is, there is provided one kind is without top cover forestair.This utility model conveniently can not only be applied
Work, improves waterproof effect, also has high insulating effect and safety good.
The technical solution of the utility model：Without top cover forestair, including multiple step plates being connected with each other, step plate is
L-shaped precast rc slab, is provided with cast-in-situ steel reinforced concrete swash plate below step plate；Cast-in-situ steel reinforced concrete
The upper surface of swash plate is disposed with screed-coat, heat-insulation layer, waterproof layer and protective layer from the bottom up, between protective layer and step plate
It is provided with space；Angle steel rest is provided with space, and the step plate is located on angle steel rest top surface.
In the aforesaid forestair without top cover, the both sides of the cast-in-situ steel reinforced concrete swash plate are provided with armored concrete
Flange, angle steel rest side are fixedly connected with armored concrete flange by nailing.
In the aforesaid forestair without top cover, heat-insulation layer is provided between the armored concrete flange and step plate and is turned over
Side, is provided with waterproof layer flange in heat-insulation layer flange.
In the aforesaid forestair without top cover, the upper and lower ends of the cast-in-situ steel reinforced concrete swash plate are respectively connected with rest and put down
Platform, half space are provided with gutter.
In the aforesaid forestair without top cover, the plate top surface of marking time is provided with building coats.
During aforesaid one kind is without top cover forestair, the screed-coat is the 1 of 20 thickness:3 cement sand beds；Protective layer is 20
Thick 1:2.5 cement sand bed.
In the aforesaid forestair without top cover, the angle steel rest surface is provided with zinc coat, angle steel rest be provided with multiple,
Every grade of step plate two ends respectively arrange two angle steel rests.
Compared with prior art, this utility model improve existing without top cover forestair structure, by arranging " L " shape
Precast rc slab as step plate, assembled after being carried by lifting during in-site installation, not only easy construction, and
And mark time relative to conventional cast-in-situ steel reinforced concrete and can also reduce concrete amount, reduces cost；Meanwhile, by arranging position
Heat-insulation layer and waterproof layer between step plate and cast-in-situ steel reinforced concrete swash plate is incubated and waterproof, it is to avoid conventional waterproof face
Layer carries out multiple bending with step plate, not only easy construction, additionally it is possible to lift integrity and the water resistance of waterproof layer, improves
Waterproof effect, can reach I grade of waterproof of buildings waterproof grade, and prevent heat-insulation layer from peeling off, improve heat insulation effect and peace
Quan Xing；The location and installation that step plate can be facilitated by space and angle steel rest, further facilitates construction.Additionally, this practicality is new
Type can facilitate the installation of angle steel rest, further facilitate construction by arranging nailing and armored concrete flange；By arranging
Heat-insulation layer flange can coordinate heat-insulation layer to play heat insulation effect, effectively prevent cold-heat bridge；Waterproof layer is coordinated by waterproof layer flange
Waterproof effect is played, waterproof effect is further improved；Can facilitate draining by gutter is arranged on half space, prevent from accumulating
Water phenomenon.Therefore, this utility model can not only convenient construction, improve waterproof effect, also have low cost, high insulating effect and
The good advantage of safety.
