The thickness of interlayer is 20 ~ 24mm, internal layer and outer field thickness are 6 ~ 8mm, the thickness of such interlayer is approximately internal layer or outer field 3 times, this mode makes the interlayer be made up of honeycomb paper core can improve the mechanical strength of whole construction formwork well, due to template and concrete combine together form body of wall after avoid removing and a part as body of wall uses, the intensity therefore by improving construction formwork can ensure the application life of body of wall entirety.
In the construction formwork of above-mentioned free removal, described skin is silicic acid cover plate.Because shaping rear internal layer and body of wall combine together, outer just nature uses as a metope of whole body of wall, also calcium silicate board is adopted by skin can to improve globality and as intensity due during wall and surface, there is the performance of fire-proof and damp-proof, can extend well shaping after application life of body of wall.In addition, color spraying can also be carried out to superficies, promote aesthetic property.
In the construction formwork of above-mentioned free removal, described superficies adopt water resistance putty to whitewash.
Because concreting is fused to whole body of wall with whole template on internal layer, therefore after body of wall fusion is shaping, outer field surface can use as the metope of whole body of wall, by adopting water resistance putty to whitewash the waterproof and dampproof performance that can improve superficies at superficies, body of wall application life so also can be extended.
Compared with prior art, calcium silicate board uses as internal layer by the construction formwork of this free removal, can combine together with internal layer after making concreting on internal layer, thus construction formwork is used as a part for the body of wall after shaping, eliminate the process of dismounting, thus also just eliminate because of dismounting the infringement that body of wall causes, in addition, the connection area between body of wall and template can be increased by the shrinkage pool on internal layer surface, improve bonding strength, template is not easily separated with body of wall.
