2) make the steel form of corresponding size and quantity, comprise bottom integrated steel plate (1), a stair exponent number Central Standard marks time template (2), template (3) that is marked time, template (4) of marking time under; Described bottom integrated steel plate (1) is made according to stair size, the bending of described bottom integrated steel plate two ends, upper end after bending is used for being connected with upper mounting plate plate, lower end is used for being connected with lower platform plate, and the top and bottom length after bending is suitable with the mark time width of template (4) under template of above marking time (3) and respectively;
3) stair template is installed: marked time by each adjacent Central Standard between template (2), between Central Standard template (2) with described bottom integrated steel plate (1) and be fixedly connected with, by mark time template (3) with under template (4) template (2) of marking time with corresponding Central Standard respectively of marking time be fixedly connected with; The mark time both sides of template (2) of each Central Standard are right-angled trapezium, and the slope of trapezoidal hypotenuse is consistent with stair slope, and the slope of bottom integrated steel plate (1) is consistent with stair slope;
4) guaranteeing that stair template can held stationary part fixed hoisting ring (6) in lifting process, hoisting ring diameter must meet lifting load requirement.
5) by stair template hoisted in position that step (3) connects, on mark time template (3) and under mark time template (4) and bottom integrated steel plate junction anchor hole should respectively with reserved anchor hole aligned in position on upper mounting plate beam and lower platform beam, with crab-bolt by mark time template (3) and under template (4) of marking time be separately fixed on upper mounting plate beam and lower platform beam, cut away hoisting ring after having lifted;
6) concreting: to mark time template penetration concrete from stair template intermediate standard topmost, upper level mark time template build full after, under gravity, concrete automatically flows into next stage and marks time in template, until whole stair template build full till.
The advantage that the present invention has and good effect are:
(1) steel form rigidity stability is strong, and concrete is not yielding, and presentation quality is good, ensure that workmanship;
(2) steel form is as permanent formwork, can direct installation in position during construction, without the need to dismounting, simple to operate, saves man-hour, construction safety;
(3) timber is saved, protection of the environment;
(4) steel form and concrete can be bonded to overall co-operation, thus effectively improve the bearing capacity of stair.
Accompanying drawing explanation
Fig. 1 is the structural representation of this combined staircase;
Fig. 2 is that standard is marked time template schematic diagram;
Fig. 3 is template schematic diagram of marking time up and down;
In figure: 1-integral plate, 2-standard are marked time template, 5a, high-strength bolt, 5b-crab-bolt, 6-hoisting ring, 7-bolt hole, the 8-anchor hole of marking time under template, 4-that template, 3-mark time.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
See Fig. 1, stair process of the present invention is as follows:
(1) size of stair is measured and checked, mainly comprise the width of stair, length, step number of marking time, the width etc. of marking time.
(2) template is made.According to the steel form of data make corresponding size and quantity, mark time under template 3, that template 2, that described steel form comprises integral plate 1, a stair exponent number Central Standard is marked time is marked time template 4, high-strength bolt 5a, crab-bolt 5b and hoisting ring 6.
Template concrete construction method is as follows:
First make described bottom integrated steel plate 1 according to stair size, bending is carried out in template width position of marking time up and down, described integral plate two ends, and bending angle is consistent with the slope of stairs, and opens bolt hole at the bolt position place be connected with described template 2,3,4 of marking time;
Make respectively described standard mark time template 2, on mark time template 3 and under to mark time template 4, and open bolt hole in relevant position, as shown in Figures 2 and 3;
Be connected between described standard form 2, between standard form 2 with described bottom steel plate 1 with described high-strength bolt 5a, described template 3,4 of marking time up and down is connected with described standard form 2 respectively, does not now connect mark time up and down template 3,4 and bottom steel plate 1;
At relevant position welding hoisting ring 6, hoisting ring diameter must meet lifting load requirement, and moment of flexure mechanical calculation must be carried out in welding position, guarantees that stair template can held stationary in lifting process.
(3) installation form.By steel form hoisted in position, the anchor hole of template of marking time up and down and steel plate junction should with reserved anchor hole aligned in position on upper and lower landing beam, with crab-bolt 5b, template of marking time up and down is separately fixed on upper and lower landing beam, after having lifted, cuts away hoisting ring.Note in model sheetinstallat work progress carrying out suitable adjustment to stair step absolute altitude, original position and levelness.
(4) concreting.From stair template template penetration concrete of marking time topmost, upper level mark time template build full after, under gravity, concrete automatically flows into next stage and marks time in template, until whole steel form build full till.After having built, concrete surface is automatically smooth, and outward appearance is good.
(5) concrete curing.Note the destruction artificial to concrete, until can normally use, without the need to dismantling template, steel form is stayed in stair as permanent template, can replace the arrangement of reinforcement in concrete at the steel plate of concrete base, effectively improves concrete bearing capacity.
The advantage that the present invention has and good effect are: steel form rigidity stability is strong, and concrete is not yielding, and presentation quality is good, ensure that workmanship; Steel form, can direct installation in position during construction as permanent formwork, without the need to dismounting, simple to operate, saves man-hour, construction safety; Save timber, protection of the environment; Steel form and concrete can be bonded to overall co-operation, thus effectively improve the bearing capacity of stair.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of form, these all belong within protection scope of the present invention.
