Art
The invention belongs to building engineering field, and in particular to a kind of stair construction method.
Background technology
Stair are the vertical transportation facilities in building, its quality for it is normal use and emergency case process have to
Close important effect.At present stair are generally dissipated using wooden template and spell construction, and formwork rigidity stability is poor, Jing often occur race mould,
The phenomenons such as displacement, affect construction quality；And the formwork time is long, installation and removal inconvenience may make when concrete strength is inadequate
Into destruction, construction is complicated, and efficiency is low；It is less that plank sheathing makes material source, welding and relatively costly.Therefore, wooden template is used
The method that scattered spelling carries out stair construction has much room for improvement.
The content of the invention
The present invention provides a kind of stair construction method to solve the above-mentioned problems in the prior art.This can make
Obtain stair constructing operation simply and stair quality and reduces cost can be improved.The technical solution used in the present invention is：
A kind of construction method of compoboard stair, comprises the following steps：
1) size of stair is determined, main width including stair, length, step number of marking time, the width marked time.
2) steel form of corresponding size and quantity is made, including bottom integral plate (1), stair exponent number Central Standard are stepped on
Step template (2), template (3) of marking time on, template (4) of marking time under；The bottom overall steel is made according to stair size
Plate (1), the bottom integral plate two ends bending, the upper end after bending is used to be connected with upper mounting plate plate, and lower end is used for flat with lower
Platen is connected, the top and bottom length after bending respectively with mark time the width phase of template (4) under template of above marking time (3) and one
When；
3) stair template is installed：Each adjacent Central Standard is marked time between template (2), Central Standard template (2) with
Be fixedly connected between the bottom integral plate (1), template of marking time by (3) and under mark time template (4) respectively with it is corresponding in
Ministerial standard template (2) of marking time is fixedly connected；The mark time both sides of template (2) of each Central Standard are right-angled trapezium, and trapezoidal is oblique
The slope on side is consistent with stair slope, and the slope of bottom integral plate (1) is consistent with stair slope；
4) guarantee stair template during lifting can fixed hoisting ring (6) in place of held stationary, lift by crane ring diameter
Lifting load requirement must be met.
5) the stair template lifting for connecting step (3) is in place, template of above marking time (3) and under mark time template (4) and bottom
The anchor hole of portion integral plate junction should reserve anchor hole aligned in position with upper mounting plate beam and lower platform beam respectively, use crab-bolt
Template of marking time by (3) and under template (4) of marking time be separately fixed on upper mounting plate beam and lower platform beam, cut away after the completion of lifting
Suspension ring；
6) casting concrete：Mark time template penetration concrete from the intermediate standard of stair template the top, upper level is marked time
After template is poured completely, under gravity, concrete automatically flows into next stage and marks time in template, until whole stair template is poured
Till full.
The present invention has the advantages and positive effects that：
(1) punching block panel stiffness stability is strong, and concrete is unlikely to deform, and presentation quality is good, it is ensured that construction quality；
(2) steel form can be mounted directly in place, simple to operate without the need for dismounting, saving work as permanent formwork during construction
When, construction safety；
(3) timber, environmental protection are saved；
(4) steel form and concrete can bond integral cooperation, so as to effectively increase the bearing capacity of stair.

Specific embodiment
Embodiments of the invention are described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the stair process of the present invention is as follows：
(1) size of stair is measured and is checked, main width including stair, length, step number of marking time, marked time
Width etc..
(2) template is made.According to data make corresponding size and the steel form of quantity, the steel form includes integral plate
1st, stair exponent number Central Standard being marked time template 4, high-strength bolt 5a, the crab-bolt of mark time under template 3, of mark time in template 2,
5b and hoisting ring 6.
Template concrete construction method is as follows：
First the bottom integral plate 1 is made according to stair size, the integral plate two ends are marked time up and down template width
Degree carries out bending at position, and bending angle is consistent with the slope of stairs, and in the bolt position being connected with the template 2,3,4 of marking time
Open bolt hole in place；
Make respectively the standard mark time template 2, on mark time template 3 and under mark time template 4, and open spiral shell in relevant position
Keyhole, as shown in Figures 2 and 3；
To be connected with the high-strength bolt 5a between the standard form 2, between standard form 2 and the bottom steel plate 1,
The template 3,4 of marking time up and down is connected respectively with the standard form 2, is now not connected to mark time up and down template 3,4 and bottom steel
Plate 1；
Hoisting ring 6 is welded in relevant position, lifting ring diameter must meet lifting load requirement, and welding position must carry out moment of flexure
Mechanics Calculation, it is ensured that stair template being capable of held stationary during lifting.
(3) installation form.Steel form is lifted it is in place, template of marking time up and down and the anchor hole of steel plate junction should with it is upper and lower
Anchor hole aligned in position is reserved on landing beam, template of marking time up and down is separately fixed on upper and lower landing beam with crab-bolt 5b, lifted
After the completion of cut away hoisting ring.Note fitting stair step absolute altitude, original position and levelness in model sheetinstallat work progress
When adjustment.
(4) casting concrete.From the template penetration concrete of marking time of stair template the top, upper level template of marking time is poured
Man Hou, under gravity, concrete automatically flows into next stage and marks time in template, till whole steel form is poured completely.Pour
After the completion of building, 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 for dismantling template, steel
Template is stayed in stair as permanent template, the arrangement of reinforcement in the steel plate of concrete base can replace concrete, is effectively improved
The bearing capacity of concrete.
The present invention has the advantages and positive effects that：Punching block panel stiffness stability is strong, and concrete is unlikely to deform, outward appearance matter
Measure, it is ensured that construction quality；Steel form can be mounted directly as permanent formwork, during construction it is in place, without the need for dismounting, operation letter
It is single, save man-hour, construction safety；Save timber, environmental protection；Steel form and concrete can bond integral cooperation,
So as to effectively increase the bearing capacity of stair.
Although being described to the preferred embodiments of the present invention above in conjunction with accompanying drawing, the invention is not limited in
The specific embodiment stated, above-mentioned specific embodiment is only schematic, be not it is restricted, this area it is common
Technical staff in the case of without departing from present inventive concept and scope of the claimed protection, may be used also under the enlightenment of the present invention
To make many forms, these are belonged within protection scope of the present invention.
