Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is applicable to construct between all reinforced concrete stairs, is particularly useful for the construction of typical floor.
As illustrated in fig. 1 and 2, in the utility model, steel stair template comprises two cant beams 1 that can be erected between adjacent levels stair turntable, between two cant beams 1, parallel interval is arranged, be connected and fixed respectively by two crossbeams 2 between the two ends that two cant beams 1 are corresponding, two crossbeams 2 are parallel to each other, and form rectangular mould bases.The outside (i.e. the two ends of mould bases) of two crossbeams 2 fixedly mounts two nuts, 6, two nut 6 intervals respectively and arranges, and each nut 6 is all screwed into and regulates screw mandrel 7 pairs of mould bases to support, rotate the height regulating screw mandrel 7 can adjust mould bases.The below of mould bases from top to bottom (namely from the top of mould bases to bottom) uniform intervals arranges nine side forms of marking time; Side form of marking time is made up of side template 3 and stiffening girder 5, and back and the stiffening girder 5 of side template 3 are connected and fixed, and side form of marking time is parallel with crossbeam 2; The both sides of stiffening girder 5 are connected and fixed respectively by montant 4 and cant beam 1.The length of side form of marking time is greater than the width of mould bases.Adjacent marking time between side form on the right of mould bases outside the side of staircase body of wall (namely near) cant beam 1 adopts steel plate to connect, and namely goes up one and to mark time the bottom of side form and the top junction steel plate of next side form of marking time; Adopt steel plate 10 to carry out full envelope between the lateral surface of adjacent side form of marking time, the top of steel plate is fixedly connected with angle steel as wing limit 8, and wing limit 8 is perpendicular with steel plate 10, and wing limit 8 is parallel with cant beam 1; Wing limit 8 has several perforates, for being connected with staircase wall form.Two crossbeams 2 install 2 reinforcing bar suspension ring respectively, for lifting and the movement of steel stair template.
Cant beam 1 in the present embodiment and crossbeam 2 adopt 10# channel-section steel, and side template 3 adopts 6 steel plates, and stiffening girder 5 adopts 8# channel-section steel, and montant 4 adopts 5# angle steel, and wing limit 8 adopts 4# angle steel, and reinforcing bar suspension ring adopt 20mm reinforcing bar.Side form of marking time in the present embodiment is nine, steel stair template should be known as those of ordinary skill in the art, side form quantity of marking time, adjacent Distance geometry selection of marking time between side form can according to practice of construction need carry out changing or adjusting.
In the present embodiment, adjacent marking time between side form on the right of mould bases outside cant beam 1 adopts steel plate to connect, adopt steel plate 10 to carry out full envelope between the lateral surface of adjacent side form of marking time, the top of steel plate 10 is fixedly connected with angle steel as wing limit 8 for being connected with staircase wall form.In practice of construction process, can according to the difference in disparity items stair direction, steel plate is adopted to connect adjacent the marking time between side form outside mould bases left side cant beam 1, adopt steel plate 10 to carry out full envelope between the lateral surface of adjacent side form of marking time, the top of steel plate 10 is fixedly connected with angle steel as wing limit 8 for being connected with staircase body of wall exterior sheathing.As principle, steel stair mould upper limb limit 8 must near staircase body of wall side, with staircase body of wall exterior sheathing Connecting groups mould.
As shown in Figure 3, staircase wall form comprises body of wall exterior sheathing 19 and wall internal mould plate 16; Wall form all adopts 6 thick steel facings, steel facing has screw hole spaced apart, and the back side of steel facing adopts vertical back cord 15 to reinforce, and back cord 15 spacing is about 450mm; The surrounding at the steel facing back side adopts 4# angle steel 20 bound edge, and angle steel 20 is provided with multiple perforate.The lower side of body of wall exterior sheathing 19 is relative corresponding with wing limit 8 structure of steel stair template, perforate on the lower side angle steel 20 of body of wall exterior sheathing 19 with wing limit 8 on position of opening corresponding, during group mould body of wall exterior sheathing 19 lower side on angle steel 20 be connected and fixed by screw 21 with the wing limit 8 of steel stair template.
The construction sequence of carrying out poured up at a time between architectural stair of above-mentioned steel stair template and staircase wall form is utilized to be:
Absolute altitude, the size of the staircase 1, provided according to Architecture and structure working drawing, design the size of template, according to staircase wall internal mould plate and the exterior sheathing of size processing said structure.
2, the processing of steel stair template is completed according to design size and said structure.
3, colligation stair reinforcing bar qualified by inspection after, first by after steel stair formwork hoisting to the position of setting, pad respectively in the below of four adjusting screws 7 and establish and treat the concrete pad of concreting with label, adopt the position of crow bar adjustment stair template, adjusted the absolute altitude of marking time by adjusting screw 7, ensure the accurate of its position.
4, as shown in Figure 3, colligation staircase wall steel bar and qualified by inspection after, first prop up vertical staircase inner side template 16, and on reinforcing bar, arrange cement support, cement support interval 1000mm, in quincuncial arrangement; Then, lifting the positive facade exterior sheathing of staircase and both sides exterior sheathing successively according to joining mould drawing, after rigging out, adopting iron wire to be undertaken temporary fixed by exterior sheathing 19 and wall steel bar; Subsequently, the wing limit 8 in steel stair template is fixed by screw 21 with the angle steel 20 on exterior sheathing 19 lower side on correspondence position; Positive for staircase facade exterior sheathing and both sides exterior sheathing are connected and fixed by screw 21 mutually.
5, as shown in Figure 4, after staircase body of wall inner and outer template installs, wall bushing 18 and connecting bolt 11, main back cord 14 after adjusting mold plate verticality, tighten tapered cup nut 12 are installed successively, pad 13 is set between tapered cup nut 12 and inner and outer template, realizes fixing between inner and outer template; In work progress, main back cord 14 is installed its horizontal absolute altitude and must be ensured unanimously, simultaneously above stair step with mark time the main back cord 14 that be arranged in parallel.
6, according to the label of design, disposable integral concreting is carried out to staircase body of wall and stair;
7, after staircase concreting, when intensity reaches 1Mpa(4Mpa in winter) start to remove body of wall inner and outer template, first remove the tapered cup nut 12 on bolt 11, remove main back cord 14, connecting bolt 11 from top to bottom successively, mark time and exterior sheathing connecting screw 21, connecting screw 21 between exterior sheathing, then body of wall inner and outer template is prized gently with crowbar, make template leave body of wall, vertical transportation machinery such as recycling tower crane etc. is transported to stockyard, after tear steel stair template open.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
