Implantation de façades en pierre

The external wall stones are basically required to be installed by dry hanging or back-bolt installation; conventional stone dry hanging adopts chip type dry hanging, and the chips are mainly used on the upper and lower end faces and left and right sides of the stone. This installation method is mainly suitable for The wall that is vertical to the ground, and the size should not be too large; for the inclined wall or the outer wall with large size and heavy weight, the back bolt installation method is often used.

Before setting out, you must be familiar with the design drawings, look at the plan, elevation, and section node diagrams, and understand the parts that need to be processed and the installation method of the stone; in principle, when we go to set out, the steel frame has been completed, and the size of the stone is measured according to the steel frame It is more accurate, because the steel frame is more accurate than civil engineering, and the steel frame is a relatively accurate measurement standard; of course, we cannot blindly believe in the steel frame, and we must check the steel frame in conjunction with the large-scale installation drawing. Stakeout dimensions include plane dimensions and height dimensions.

When we measure the plane size, we take the outer side of the steel frame as the basis, divide it into multiple relatively independent areas according to the different elevations according to the plan, and number the areas in a counterclockwise direction according to the plan. In order to ensure the measurement accuracy during measurement, it can be unified Measure at the height of the horizontal line. Where there are windows, the position of the window must be accurately positioned. If the window frame is not installed, we cannot measure accurately. The size of the window line and side panels must be combined with the size of the window frame joints, and more Point measurement to check the flatness of the window frame installation, the purpose is to determine the exact blanking size of the side panel.

The basis and standard for height measurement is the horizontal line. The elevation on the drawing is for reference, and the height should also be divided into areas. It can be divided reasonably according to the division style of the exterior drawing and the floor height. The positioning size of doors and windows is also very important! After the size measurement of the steel frame is completed, we draw the size drawing of the finished surface of the stone according to the installation node diagram. The division and layout of the stone should first refer to the customer’s design specification size, combined with the position of the doors and windows, and make appropriate adjustments to the plate specifications. The yield rate of stone materials must also ensure the overall effect of the design.

For the treatment of yin and yang angles, it is judged according to the design node plan whether it is necessary to add allowance for stone cutting? Because there will be errors in measurement, processing and installation, the required size for the left and right sides are positive angles should be as accurate as possible! For the treatment plan of the male corner, it is recommended to use a plate to press the plate or leave the chicken beak to skim the bottom. It is recommended to use a plate to press the inner corner and add an appropriate margin to the pressed side.

The external wall construction generally requires seams to be left, and the specific data is determined according to the design requirements. When typesetting and dividing, it is necessary to consider the seams to determine the size of the stone material.
