Piquetagem cilíndrica

As colunas são produtos de pedra decorativa relativamente independentes. A maioria das colunas são colunas independentes, que consiste em um cabeçalho de coluna, corpo da coluna e base da coluna; algumas colunas no lobby estão conectadas à galeria de corridas de cavalos.

A engenharia civil do cilindro pode ser redonda ou quadrada. Before setting out, you should check the civil engineering drawings and decoration design drawings to find the civil engineering dimensions of the cylinder and the size of the finished decorative surface. See the node diagram to understand the construction method.

The plane size of the square civil construction can be directly measured with a tape measure. Considering that civil construction errors are inevitable, several points can be selected for measurement according to the height of the civil construction columns; visually judge the size of the error, and if necessary, it is best to complete the stone decoration Put the surface on the ground, or fix a wooden formwork (finished surface) on the top of the column, check the distance from the completed surface to the civil work with a hanging hammer (that is, check the verticality of the column), and judge whether the construction space is sufficient based on the construction node diagram ? For circular civil construction, you can use a tape measure to measure the circumference of the civil construction cylinder, then calculate the diameter, and finally use the finished surface to detect.

The height of the column is another key parameter. It is inaccurate to directly measure the civil construction, and it needs to be calculated according to the elevation and the horizontal line of the site. The elevation of the lower bottom surface of the column base generally has a horizontal line that can be calculated by reference. The elevation of the upper end surface of the column head should be checked on the ceiling drawing, and a reference point can be found on the civil wall for measurement.

According to the size of the interface between the column head and the ceiling and the interface between the column base and the ground, it is judged whether to increase the margin in height. When the horse gallery is connected with the columns, it is necessary to consider the reasonable contact between the arc plate of the column body and the horse gallery in combination with the section of the horse gallery to facilitate processing and construction; the height of the column body can be considered by dividing the column body into three sections.

The parts in the circumferential direction should be divided reasonably according to the diameter and the processing characteristics of the arc plate. For the arc plate whose civil works are square, it is recommended to divide into four pieces.
