Embodiment Construction

[0029] The present invention will be further described below in combination with specific embodiments.

[0030] A method for determining the quantity of nails required for drawing on an earthy wall, in the present embodiment, the nails are specifically U-shaped nails; comprising the following steps:

[0031] (1) The cutting area is 1m 2 hanging net, weigh its mass m 1 , and then multiplied by the acceleration of gravity to get its gravity G 1 ;

[0032] (2) Take a hanging net with a certain area, immerse it in a measuring cylinder equipped with water, measure the water volume increased by the water in the measuring cylinder, which is the hanging net volume of the certain area; then weigh the certain area. The quality of the hanging net of the area, the quality of the hanging net is divided by the volume of the hanging net to obtain the density ρ of the hanging net of the definite area 1 ; Measure the thickness d of the hanging net of described definite area by vernier cali...

Abstract

The invention provides a method for determining the number of nailed nails required for drawing on a soil wall space. The method comprises the steps that (1) hanging nets with an area of 1 m<2> are cut and obtained, the mass is weighed as m1, and then m1 is multiplied by gravity acceleration to obtain gravity G1; (2) the hanging net with a certain area is picked, the mass of the hanging net is divided by the volume of the hanging net to obtain the density rho1 of the hanging net with the certain area, and the thickness d1 of the hanging net with the certain area is determined by a vernier caliper; (3) a fresh attachment is picked, the density rho2 of the attachment is measured by a cutting-ring method, and the thickness z2 of application of the attachment is in the range of 0.5-1.0 cm; (4)the mass m2 of the attachment body after application to the soil wall space per unit area is determined; (5) the mass m3 of pigment per unit area is determined; and (6) the total gravity G of materials required for drawing on the soil wall space is determined. According to the technical scheme, high process quality, reliable results and other effects can be achieved by the method for determiningthe number of the nails.

Description

technical field [0001] The invention relates to a method for determining the quantity of nails required for painting on an earthy wall surface. Background technique [0002] In my country, there are many earthen houses, that is, houses made of adobe masonry. The walls of these houses are generally made of mud. Some earthen houses have been around for a long time and have strong historical protection value. With the rise of modern art, painting on the wall has become a fashion. However, the soil wall surface has low adhesion, so it is impossible to directly apply paint for painting. Painting on this wall surface requires prior treatment of the wall surface, such as hanging nets and smearing attachments that are new soil. U-shaped nails are required to hang the nets. It is nailed into the soil wall to prevent it from falling off. The number of U-shaped nails is very important to the firmness of the hanging net and paint. If the number of U-shaped nails is not enough, it is e...
