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 embodiments.

[0054] The construction method of large-span variable cross-section and haunched slab formwork includes the following steps:

[0055] Step 1: Making auxiliary tool for haunched board template-special platform for cutting haunched board template

[0056] The special platform for cutting the haunched board template includes a supporting frame body, a telescopic steel inclined plane, and a fixed platform for the cutting machine;

[0057] The support frame body is a steel structure, the support frame body is welded by steel square pipes, and includes four uprights and eight crossbars. Two crossbars are connected up and down between the upright and the uprights, four Two of the uprights are longer than the other two, and the two longer uprights are adjacent;

Abstract

The invention provides a construction method of a large-span variable-section haunching plate formwork. The construction method comprises the steps of manufacturing a haunching plate formwork cuttingauxiliary tool, and manufacturing a haunching plate formwork auxiliary tool. High-precision shaping and accurate positioning installation of the formwork are realized. The construction method using the technical scheme has the beneficial effects that by using the construction process and the auxiliary tools, the tight splicing of the haunching plate formwork without slurry leakage can be ensured;after formwork dismounting, no edge exists, and the appearance is good; in the subsequent construction procedure, labor investment for regulation is not needed, so that the time and the labor are saved; the construction progress can be effectively accelerated; and through the special auxiliary tools, high cutting precision and high installation precision of the haunching plate formwork can be ensured. The special auxiliary tools have the characteristics that the structure is simple, the processing is convenient, and the special auxiliary tools can be repeatedly used.

Description

Technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method and device of a large-span variable cross-section plus haunched plate formwork. Background technique [0002] In order to meet the requirements of modern buildings for storey height, self-weight, large space, free spacing and seismic resistance, a large-span floor structure with reasonable stress, economical and concise-variable cross-section and haunched floor slabs has emerged. It has the advantages of good structural integrity, high rigidity, light weight and high bearing capacity. Since the structure has no secondary beams, the force of the plate surface is directly transmitted to the main beam through the haunched plates. Therefore, controlling the positioning of the haunched plates is the focus of quality control, and the accurate positioning of the templates requires high-precision size corresponding templates. [0003] In the construction process of...
