A construction method of an inclined roof formwork support system comprises the following specific steps:

the method comprises the following steps: building an inclined roof model by using BIM software, determining the arrangement position and the interval of upright rods and the bolt adjusting height according to the thickness and the inclination angle of an inclined roof plate, designing and checking the size of a primary and secondary aluminum frame of a support system, wherein the primary and secondary aluminum frame unit is 1.2m multiplied by 1.2m or 0.9m multiplied by 0.9m, and processing and shaping the aluminum frame according to a construction deepening result in a factory;

step two: set up the support frame, adopt fastener formula full hall support frame (henceforth simply called the scaffold), the shore is installed on the scaffold top, and is concrete, and the shore adopts the mode that cup joints to be connected with the scaffold pole setting. Connecting the top support with the support frame;

step five: after the template is paved, the concrete can be poured by binding the reinforcing steel bars according to the conventional method after the examination and acceptance are qualified.

It should be noted that, the technical solution of the present invention is only technically explained by using a single supporting point, that is, the technical solution and the accompanying drawings of the present invention only list a supporting system under the condition of a top brace 7, and in the actual construction process, the number of supporting points can be increased according to the size of the actually constructed sloping roof, so as to meet the actual construction requirements.

The specific working principle is as follows: in actual use, construction operation is carried out according to the steps of the construction method.

The supporting structure is formed by assembling a primary and secondary corrugated aluminum frame 201 in a unit body modularization mode, the template manufacturing process is transferred to a factory, only the template is installed and disassembled on a construction site, and the primary and secondary corrugations are formed and processed by aluminum alloy sections.

The connection of back shore 7 and primary and secondary stupefied aluminium frame 201 is that adjusting bolt 8 is articulated with spacing angle steel 5, when 4 adjusting bolt 8 groups were detained in spacing angle steel 5 altogether, spacing angle steel 5 and adjusting bolt 8 total 4 contact points, and arbitrary wherein three contact point of these 4 contact points all are not collinear, and two sets of high bolt 801's height is the same all the time moreover, and two sets of low bolt 802's height is the same all the time. When the height of the adjusting bolt 8 is finely adjusted according to actual requirements, because the adjusting bolt 8 is directly buckled in the rectangular space 501 (the space formed between the limit angle steel 5 and the primary and secondary aluminum frame 201), the primary and secondary aluminum frame 201 and the adjusting bolt 8 are sleeved like wearing a hat, the limit angle steel 5 is the hat of the adjusting bolt 8, that is, the whole primary and secondary aluminum frame 201 is buckled on the adjusting bolt 8 through the limit angle steel 5, when the actual height of the adjusting bolt 8 changes, the slope installation angle of the primary and secondary aluminum frame 201 is finely adjusted, the adjustment of the installation slope angle of the primary and secondary aluminum frame 201 is realized, that is, the adjustment of the installation slope of the template panel installed on the primary and secondary aluminum frame is realized, for example, when the height of the low-position bolt 802 is unchanged, the actual height of the high-position bolt 801 is increased, the slope angle of the primary and secondary aluminum frame 201 is increased, and vice versa. Under the condition that the actual height of the 4 groups of adjusting bolts is determined, a plane can be determined by the 4 contact points, the determined plane is an installation inclined plane of the primary and secondary corrugated aluminum frames 201, namely an actual installation inclined plane of the formwork panel 1, at the moment, the left and right, front and back movement of the primary and secondary corrugated aluminum frames 201 is limited by the limiting angle steel 5, the upward movement of the primary and secondary corrugated aluminum frames 201 is limited by the gravity of the primary and secondary corrugated aluminum frames 201 and the formwork panel 1, the downward movement of the primary and secondary corrugated aluminum frames 201 is limited by the adjusting bolts 8, the buckling connection of the 4 groups of adjusting bolts 8 and the limiting angle steel 5 and the gravity of the primary and secondary corrugated aluminum frames 201 and the formwork panel 1 limit the slight rotation of the primary and secondary corrugated aluminum frames 201, and therefore under the condition that the actual height of the 4 groups of adjusting bolts is determined, the inclined plane angle of the primary and secondary corrugated aluminum frames 201 is determined and stable.

Low level bolt 802 passes horizontal slip hole 10, and the purpose makes low level bolt 802 carry out the fine setting of sliding on the horizontal direction through horizontal slip hole 10, mainly solves roofing inclination and changes at 45 within ranges, if do not set up the fine setting of sliding, will lead to along with inclination's change, and the adjusting bolt 8 of shore 7 and 5 unable one-to-one in position of spacing angle steel lead to the unable seat of strong point on the adjusting bolt 8 of self-control shore, and the unable installation of roofing template panel 1.

After the construction is completed, the formwork is disassembled, because the primary and secondary aluminum frame 201 and the top brace 7 are directly buckled through the limiting angle steel 5, the formwork panel 1 and the primary and secondary aluminum frame are detachably connected, the primary and secondary aluminum frame 201 and the formwork panel 1 can be disassembled one by one in a unit form, and then the top brace 7 is disassembled from the scaffold so as to be used in a turnover manner.

In view of the above, the present invention achieves the intended objects.
