Embodiment 1

[0041] The embodiment of the present invention discloses a method for installing and constructing a formwork for a special-shaped concrete structure, comprising the following construction steps:

[0042] Step 1: According to the design drawings, establish a steel structure model, conduct collision analysis on the steel structure model, and export the size data and position labels of the steel structure model;

[0043] Step 2: The construction site is positioned and laid out, the horizontal control line is drawn on the construction ground, and the position of the horizontal keel is determined by the spirit level;

[0044] Step 3: Binding the steel bars according to the positions marked by the positioning and lay-out lines, when the steel bars are bound, a multi-faceted steel mesh is formed by tying the steel bars in the form of broken lines, and the panels 1 are installed on both sides of the steel mesh in turn;

[0045] Step 4: Install the back corrugation on the installed pan...

Embodiment 2

[0047] On the basis of Example 1, increase:

[0048] In step 1, the reinforcement structure model is subjected to collision analysis, including structural collision analysis when the installation is completed and collision analysis during the installation process. The collision analysis during the installation process is realized by simulating the installation process with BIM software.

[0049] In step 2, the position of the main keel 2 is determined by the level meter, and the level meter determines the position of a main keel 2 by testing two points.

[0050] In step 3, the panels 1 are sequentially installed on both sides of the steel mesh, and at the same time, the panels 1 on both sides are connected and fixed by means of tension bolts.

[0051] When installing the main keel 2 in step 4, first connect the adjacent main keel 2 with the hinge 21, and then install the main keel 2 on the panel 1 as a whole. Fit, and then use the self-locking block 23 and the hinge bolt 22 to ...

Embodiment 3

[0053] On the basis of Example 2, increase:

[0054] In step 3, the HVAC pipes and the water pipes are reserved and buried during the steel bar binding process.

[0055] After the installation of the panel 1 is completed, the position and angle of the panel 1 are compounded by a level and an inclinometer, and leveled by an electronic automatic leveler.

[0056] One end of the locking block 23 is mounted on one end of the hinge 21 by the locking shaft 231 , and the other end of the locking block 23 controls the locking block 23 to rotate around the locking shaft 231 through the toggle lever 233 . 23 is pushed by the locking spring 232 and realizes the locking function by engaging with the toothed plate 211 .

[0057] After the installation of the main keel 1 is completed, the position and level of the main keel 1 are compounded, and the angle of the main keel 1 is adjusted by the toggle lever 233 .

Abstract

The invention relates to the technical field of building curtain wall construction, in particular to a special-shaped concrete structure formwork installation construction method. The construction method comprises the specific construction steps that a steel bar structure model is built, collision analysis is conducted on the steel bar structure model, positioning and paying-off are conducted on a construction site, steel bar binding is conducted according to the marked positions of positioning and paying-off, panels are sequentially installed on the two side faces of a steel bar net, and back ridges are installed on the installed panels. The back ridges are composed of main keels and auxiliary keels which are perpendicular to each other, and the main keels are hinged to each other through hinges. According to the construction method, an existing special-shaped concrete structure formwork reinforcing technology is innovated, a special-shaped concrete structure formwork reinforcing system is established, a novel wall reinforcing back ridge is designed, angle control over special-shaped concrete wall, beam and plate components is achieved, perpendicularity and flatness of formworks are controlled, construction operation is simplified, machining and construction efficiency is improved, and the construction cost is reduced. The construction precision is guaranteed, the construction cost is reduced, and the project progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of building curtain wall construction, in particular to an installation and construction method for a special-shaped concrete structure formwork. Background technique [0002] With the continuous improvement of the social economy and urbanization rate, in order to adapt to the irregular plots in the central urban area and make the buildings more artistic, irregular and special-shaped structures continue to appear, and have gradually become the mainstream of new buildings in the central urban area. As a representative one, the structure has the disadvantages of many changes in modeling design, difficulty in reinforcement of the formwork, complicated procedures and large deformation of the reinforcement of the formwork. [0003] In the related art, one method adopts the method of directly installing the curved panel and the back corrugation, which is complicated in structure, difficult to manufacture, and high...
