Who has used plastic building formwork? How is the effect? What are the advantages and disadvantages?

Answers are as follows:

One, the advantages of plastic construction template are:

1, smooth and clean. Template splicing tight and flat, demolded concrete structure surface degree, finish are more than the existing technical requirements of the water template, without the second plaster, labor and materials.

2, lightweight and easy to install. Light weight, process adaptability, can be sawed, planed, drilled, nailed, can be composed of any geometric shape, to meet the needs of various shapes of building support mold.

3, easy demolding. Concrete does not stain the surface of the board, no need for mold release agent, easy to remove the mold, easy to remove dust.

4, stable and weatherproof. High mechanical strength, in the -20 ℃ to +60 ℃ temperature conditions, no shrinkage, no wet swelling, no cracking, no deformation, dimensional stability, alkali corrosion resistance, fire retardant and waterproof, rodent and insect resistance.

5, conducive to maintenance. Template does not absorb water, without special maintenance or storage.

Second, according to my understanding of the shortcomings are:

1: the quality is too heavy.

2 Strength is not very satisfactory.

3, a bit of a wood square.

Plastic building template construction process

1, the top plate plastic building template support: sub-flute spacing based on the thickness of the plate to determine the general construction conditions, less than 150 thick floor plate sub-flute spacing (center distance) of 350 ~ 400mm; 150 ~ 250 thick floor plate sub-flute spacing (center distance) of 300mm. Compared with the normal use of bamboo plywood formwork, the spacing of the secondary flute is increased by 50mm, the flatness of the concrete surface deviation is smaller, and really achieve the effect of clear water concrete.

2, shear wall plastic construction template support: wall height 2800, wall thickness 300, for example, the use of 12mm template, vertical secondary rib spacing (center distance) for 250mm; the use of 15mm template, vertical secondary flute spacing (center distance) for 300mm. compared with the normal use of bamboo plywood template, the spacing of the secondary flute, the smoothness of the surface of the concrete deviation is basically the same, but the concrete surface is smooth and clean, to achieve the effect of fair-faced concrete. The surface of the concrete is smooth and clean, achieving the effect of clear-water concrete, and the quality of view is better.
