Problems solved by technology

There are obvious shortcomings in the construction process: both of them need to be further processed to meet the structural dimensions, the processing cycle is long, and it takes more manpower to fix the wooden formwork with iron nails; It is easy to be damaged, which increases the use of wood and wastes resources; steel pipes need to be straightened on a large scale after use, which seriously wastes manpower, material resources and financial resources

Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the drawings and embodiments:

[0041] In the attached drawing: wooden formwork 1, opposite tension bolt 2, longitudinal back flute 3, transverse back flute 4, mountain clamp 5, nut 6.

[0042] For this embodiment, see attached figure 1 Attached Figure 19 ; The construction method of circular structural timber formwork with steel bars as the transverse back corrugation, the steps are as follows:

[0043] Process the size of the wooden template 1 according to the size of the circular structure;

[0044] Drill holes on the wooden template 1 according to the spacing of the tension bolts 2 to be installed, and the spacing of the tension bolts 2 is determined according to the side pressure and dumping pressure of the concrete poured on the construction wall and the on-site template support parameters;

[0045] According to the size of the drawing, determine the position of the inner and outer sides of the wa...

Abstract

The invention relates to a construction method for a wood formwork with a bigger circular structure by taking a reinforcing steel bar as a lateral rear edge. The construction method comprises the following steps of: processing a size of the wood formwork according to the size of the circular structure; punching on the wood formwork according to a distance between oppositely pulling bolts, wherein the distance between the oppositely pulling bolts is confirmed according to a lateral pressure of poured concrete of a constructed wall, a pressure for pouring the concrete and set parameters for on-site formwork; confirming inner and outer two side boundary positions of the to-be-poured and formed wall and mounting the wood formwork; mounting and fixing a first longitudinal rear edge on an outer side wall of the wood formwork; mounting the reinforcing steel bar as the lateral rear edge close to the first longitudinal rear edge; arranging the lateral rear edge above the horizontal direction of closed oppositely pulling bolt holes; mounting and fixing a second longitudinal rear edge close to the lateral rear edge; and placing the oppositely pulling bolts into the holes of the wood formwork and fastening the oppositely pulling bolts. Instead of a batten, the reinforcing steel bar is taken as the lateral supporting rear edge of the wood formwork, thereby greatly saving wood, reducing consumption and cost, and increasing the rotating times of the wood formwork. Besides, the construction method is simply and easily operated.

Description

technical field [0001] The invention relates to a construction method for a relatively large circular structure formwork in construction engineering, in particular to a construction method for a circular structural wooden formwork using steel bars as the transverse back corrugation. Background technique [0002] For circular structures in construction projects, in order to meet the requirements of structural design and construction quality, the choice of formwork back flute is the key to quality control. Generally, the choice of longitudinal back flute materials is not limited, but the horizontal back flute is affected by the shape of the structure. In the current construction process, wooden squares or steel pipes are often used as the horizontal back corrugated formwork. There are obvious shortcomings in the construction process: both of them need to be further processed to meet the structural dimensions, the processing cycle is long, and it takes more manpower to fix the ...
