Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, in which the steel form described in this embodiment and the drawings is equivalent to a large steel form:

as shown in fig. 1, a method for correcting and fixing a formwork in suspension for a large steel formwork of a concrete shear wall comprises the following steps:

s11, when the pouring of the wall concrete on the current construction floor is just finished (the concrete is just poured and is not dried), arranging a wall positioning precast block A on the upper surface of the poured wall concrete; when beam concrete pouring on the current construction floor is just finished, a beam positioning precast block B is arranged on the upper surface of the poured beam concrete;

s12, when the strength of the concrete of the wall body of the current construction floor and the dried beam reaches a preset value, detaching the large steel template and the beam template, and spraying a separant;

s13, lifting the large steel formwork to a second construction floor position;

s14, determining the axis position through the wall positioning precast block A, and installing a large steel template and a beam template of a second construction floor;

s15, repeating the steps S11-S14.

In S11, the wall positioning precast block A is formed by prefabricating plain concrete with the same label as that of the wall of the current construction floor.

The width a of the wall positioning precast block A is as wide as the shear wall of the current construction floor, and the thickness b of the wall positioning precast block A is 30-70 mm.

The thickness b of the wall positioning precast block A is 50 mm.

More than 3 wall body positioning precast blocks A are arranged on the upper surface of the cast wall body concrete.

As shown in fig. 2-4, the wall positioning precast block a is arranged at the plug board and the wall bolt of the large steel formwork. The positioning precast block A is inserted into the top plate template, and the horizontal position of the positioning precast block A is arranged corresponding to the plug board and the wall-penetrating bolt of the large-scale steel template of the wall body. In fig. 3, there are also roof supports, also called roof formwork legs, arranged below the roof formwork; a concrete floor to be poured is arranged above the top plate template; in this embodiment, as shown in fig. 5, a is equal to the width of the shear wall, and b takes a value of 50mm or about; the distance between the embedded edge position of the positioning precast block A and the upper edge of the large steel template is used as the top plate concrete thickness, and in the embodiment, the top plate concrete thickness is 220 mm; the horizontal upper edge of the positioning precast block a is located at a distance of 50mm from the upper edge of the large steel formwork in this embodiment.

As shown in fig. 6-6, the beam positioning precast block B is specifically precast by plain concrete with the same reference number as that of the beam of the currently constructed floor; the top surface elevation of the beam positioning precast block B is the same as the top surface elevation of the beam floor concrete of the current construction floor. In this embodiment, as shown in fig. 9, c is 80mm, and d is 200 mm; when the beam formwork is erected, the beam bottom support is arranged on the beam positioning precast block B, and the beam positioning precast block B is perpendicular to the beam bottom support. The horizontal position of the positioning precast block B is arranged corresponding to the position of the beam bottom support.

As shown in fig. 10 to 8, in S13, when the large steel form is lifted to the second construction floor, the high-rise building construction steel form and the handling frame are used to lift the whole lifting platform device. The bottom edge of the large steel formwork is located at the top elevation position of the floor slab concrete slab, the hanging ribs penetrate through the upper edge of the large steel formwork and are fixed on the large steel formwork 1.5 meters away from the bottom edge of the large steel formwork, and after the large steel formwork is horizontally integrally lifted to a normal position, the horizontal deviation hanging height and the verticality of the large steel formwork of a single wall body are adjusted through adjusting bolts arranged 1.5 meters away from the bottom edge of the large steel formwork. And then installing the floor slab formwork. The axis position is determined through the wall body positioning precast block A, the large steel template and the beam template of the wall body of the layer are installed, the floor slab reinforcing steel bars are bound, and the process can be repeated after the ground floor slab concrete is poured.
