Example Embodiment

[0026] Example 1

[0027] Such as Figure 1-5 As shown, a formwork reinforcement support method for an inverted flared arc shear wall includes the following steps:

[0028] 1. Lay out the line according to the drawing size and install the inner formwork 1, which is temporarily fixed by the top floor formwork;

[0029] 2. Then install the shear wall reinforcement;

[0030] 3. After the concealed acceptance of the steel bar is completed, install the outer formwork 2. During the installation of the outer formwork 2, use the steel wire to temporarily fix the inner formwork 1 and steel bars;

[0031] 4. Install the square timber corrugated 3 on the inner formwork 1 and the outer formwork 2, and install a number of pairs of tension bolts 4 at intervals, and fix the square timber corrugated 3, the inner formwork 1 and the outer formwork 2 through the tension bolts 4. 4 There are arcs made of steel bars with a diameter of 25mm on the inside of the mountain-shaped cards on both sides;

Abstract

The invention relates to a formwork strengthening and supporting method of an inverted-horn-shaped arc-shaped shear wall. The formwork strengthening and supporting method comprises the following steps that a line is placed according to drawing sizes and an inner formwork is installed; then shear wall reinforcing steel bars is installed; after conceal inspection of the reinforcing steel bars is finished, an outer formwork is installed; square wood bars are installed on the inner formwork and the outer formwork, a plurality of opposite-pulling bolts are installed at intervals, and the square wood bars, the inner formwork and the outer formwork are fixed by the opposite-pulling bolts; a central stand column is erected at an arc-shaped central point by using scaffolding tubes; holes are formed and steel stranded wires penetrate through the inner formwork and the outer formwork, after the steel stranded wires penetrate through the outer formwork, the scaffolding tubes are further arranged on the outer side of the outer formwork, after bypassing the scaffolding tubes the steel stranded wires penetrate back to be fixed on the central stand column by using lock buckles; penetrating of steel stranded wires is repeated symmetrically until all steel stranded wires are run out; and the reinforcing condition of a supporting system is checked and reinforcing for the supporting system is finished. The formwork strengthening and supporting method can greatly reduce supporting or even do not need supporting, so that relative measure fee is reduced.

Description

Technical field [0001] The invention belongs to the technical field of civil construction, and particularly relates to a form reinforcement support system for an inverted trumpet-shaped arc-shaped shear wall. Background technique [0002] With the current economic development, the shapes of buildings are becoming more and more novel, especially landmark buildings and public buildings. In order to achieve architectural effects, various large cantilever and large arc shapes are used in buildings. This kind of structure is visually bright, but there are great difficulties in construction, and it also greatly increases the construction period and construction cost. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a form reinforcement support system for an inverted trumpet-shaped arc shear wall, which solves the problems of large cantilever and large arc shape construction, which are difficult, construction period and construct...
