Factors affecting the quality of special-shaped steel formwork and how to choose

The special-shaped steel mold is a commonly used mold in construction engineering, mainly to create special-shaped buildings. This type of template is usually It adopts a customized method, so the requirements for its own quality are relatively high. So what are the factors that affect the quality of special-shaped steel formwork? Hubei Wangke Template Co., Ltd. mainly believes that there are these.

1. Adhesive quality: Mainly manifested as the performance of the synthetic resin adhesive for glue, the coordination and adjustment of each component Glue technology and other aspects.

2. The quality of the substrate: the quality of the veneer, especially the surface condition, has a great influence on the bonding strength of the special-shaped template. Therefore, sufficient attention should be paid to each process of wood segment preparation and veneer peeling, wood softening treatment should be carried out well, the peeling conditions should be controlled, and the moisture content and flatness of the veneer should be paid attention to.

3. Aging time: The length of aging time should be appropriate, and it should be able to change reasonably with climate change. The core board is integrated to reduce the stacking and separation of the core board. It is necessary to pay attention to the pressure reduction speed and the pressure reduction speed of the rubber layer, especially the more water in the slab.

4. Template gluing force: Before gluing, pay attention to the amount of glue and slab aging. In the link, the amount of glue is too large, the cost is high, and the glue layer is too thick, the internal stress increases, and it is easy to penetrate; the amount of glue is too small, which is not conducive to the infiltration of glue, and the glue layer of the special-shaped template will be incomplete.

How to choose a special-shaped steel template? The editor tells everyone as follows:

There are many types of steel templates. In daily life, we see more bridge steel models. , Cylindrical steel molds and special-shaped steel molds. Of course, each has its own purpose, and each has its own characteristics. So, how should we choose? We have already introduced the method of selecting bridge steel molds and cylindrical steel molds. Next, let me briefly talk about how to choose special-shaped steel templates.

1. When we choose this type of steel template, I recommend that everyone try to choose a medium-sized combination template.

2. Everyone knows something about it. Normally, the wall form can be assembled into a large form with a medium-sized combination formwork. Supporting and dismantling, of course, in addition to this, the entire multi-story building template can also be used to make a large template, or use an all-steel large template.

3. When no suitable steel template is found, we can make full use of the old Multi-layer boards and short residual wood squares are made into various specifications of small and medium-sized wood composite templates.

4. Judging from the current market situation, the number of arc-shaped walls is increasing day by day, and the curvature is changeable. If Once it is processed into a finalized arc template, it takes a lot of labor and materials. Therefore, we can also adjust the arc template with any radius through the adjuster. The effect is very obvious.

5. In addition to the methods mentioned above, we should also according to the company’s own conditions, as far as possible To choose the special-shaped steel template that meets the company's production.
