Problems solved by technology
The edge of the formwork cut by this process is not straight, which will cause the two formworks to be unable to be spliced tightly on the construction work surface, and then the slurry will leak. Manual adjustment is required, which is time-consuming and labor-intensive, and affects the construction process
[0004] In addition, in the existing technology, the formwork installation accuracy only depends on the personal experience of the construction workers, and there is no corresponding auxiliary construction tools

Embodiment Construction
[0053] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific examples.
[0054] The construction method of large-span variable-section plus haunch plate formwork includes the following steps:
[0055] Step 1: Auxiliary tools for making haunched board templates - a special platform for cutting haunched board templates
[0056] The special platform for cutting and adding the armpit template includes a support frame body, a telescopic steel slope, and a fixed platform for a cutting machine;
[0057] The support frame body is a steel structure, and the support frame body is welded by steel square tubes, including four columns and eight cross bars. Two of the uprights are longer than the other two, and the longer two uprights are adjacent;
[0058] The fixed platform of the cutting machine is welded and connected to the supporti...

The construction method of large-span variable cross-section and haunched slab formwork adopts the production of haunched slab formwork cutting auxiliary tools and haunched slab formwork auxiliary tools to realize the high-precision forming and accurate positioning and installation of the formwork. The beneficial effect of the technical solution of the present invention is that: using the construction technology and auxiliary tools described in the present invention, it can ensure that the formwork of the armpit plate is tightly spliced without leakage, and there is no edge after the formwork is removed and the appearance is good. In the subsequent construction procedures It does not need manual adjustment, saves time and effort, and can effectively speed up the construction process; through special auxiliary tools, it can ensure high cutting accuracy and high installation accuracy of the armpit plate template; the special auxiliary tools have simple structure, convenient processing, and can be characteristics of repeated use.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method and device for a large-span variable-section plus axillary plate formwork. Background technique [0002] In order to meet the requirements of modern buildings for storey height, self-weight, large space, free intervals and earthquake resistance, a long-span floor structure with reasonable force, economical economy, and simplicity—variable cross-section and axillary floor slabs emerged as the times require. It has the advantages of good structural integrity, high rigidity, light weight and high bearing capacity. Since there is no secondary beam in this structure, the force on the slab surface is directly transmitted to the main beam through the haunched slab. Therefore, controlling the positioning of the formwork of the haunched slab is the focus of quality control, and the accurate positioning of the formwork requires a corresponding formwork with hig...
