The construction method of the tree growth ring texture fair-faced concrete comprises the following steps:
(1) and processing and manufacturing the texture lining plates with the same thickness and width, and fixedly installing the processed texture lining plates on the base layer template according to a set fixing method.
The base layer template is a log plywood with the thickness of 12 mm. Specifically, the basic unit template is the template of each position of the concrete building that designs the preparation according to the template engineering deepening, for example roof beam, post can make into the typical forms, and the basic unit template selects for use 12mm thick log plywood, does benefit to the fixed of texture welt, and the deformation is more close.
The processed and manufactured texture lining plate is a fir finished plate with the thickness of 5mm, the width of 100mm, the smooth surface and clear and attractive tree growth ring texture, the thickness and the width are moderate, the fir finished plate is convenient to be tightly attached to a base layer template, and the molding of a curved surface and cambered surface special-shaped component template is also facilitated.
When the texture lining plate is processed and manufactured, a fir (finished fir is selected) meeting the set requirements is selected and sawn into a wood plate (the thickness is 8-9 mm), the annual ring textures meeting the construction requirements (the tree annual ring textures are clear) are selected and then planed and straightened, and the texture lining plate with the tree annual ring textures and the thickness of 5mm and the width of 100mm is manufactured (of course, finished products can be directly purchased in the market).
The texture lining plate is fixedly arranged on the base layer template through the shooting nails according to a set fixing method, the set fixing method is a distribution method of the shooting nails when the shooting nails are shot by using a manual pneumatic gun shooting nail shooter to fixedly arrange the texture lining plate on the base layer template, namely: the ejected shooting nails are arranged in three rows along the width direction of the texture lining plate, the distance from the shooting nail close to the edge of the texture lining plate is 20mm, meanwhile, the interval between the adjacent shooting nails in the length direction of the texture lining plate is less than or equal to 150mm, and the interval can be preferably 100 mm. Thus, the texture lining plate is firmly fixed on the base layer template.
In addition, when the texture lining plates are fixedly arranged on the base layer template, any two adjacent texture lining plates are in close contact with each other.
