Stone curtain wall is a form of peripheral decoration often used at home and abroad. Different building structures adopt different types, and bear different external forces during construction and use. Now, in order to ensure the effect of stone curtain wall, we will use the construction technology of stone curtain wall. Let's briefly introduce the relevant information about the construction technology of stone curtain wall

stone curtain wall is a form of peripheral decoration commonly used at home and abroad. Different building structures adopt different types, and both construction and use bear different external forces. Now, in order to ensure the effect of stone curtain wall, we will use the construction technology of stone curtain wall. Let's briefly introduce the relevant information about the construction technology of stone curtain wall

I. composition and structure of stone curtain wall

stone curtain wall is mainly composed of stone panels, stainless steel hangers, steel frameworks (columns and transverse braces), embedded parts, connectors and stone seam glue. However, the direct dry hanging curtain wall installs stainless steel hangers on the main structure without setting a steel skeleton. This practice requires that the wall strength of the main structure is high, preferably reinforced concrete wall, and that the wall flatness and verticality are good, otherwise the skeleton method should be adopted

II. Construction process of stone curtain wall

the installation and construction of stone curtain wall should be carried out after the acceptance of the main structure of the building. In order to carry out the construction quickly and with high quality, the construction organization design should be prepared for the installation and construction of stone curtain wall. The main contents of the construction organization design include: 1. Project schedule; 2. Handling and lifting methods; 3. Measurement method; 4. Installation method; 5. Installation sequence; 6. Inspection and acceptance; 7. Safety measures

according to the engineering practice experience, the installation and construction methods of stone curtain wall mainly include the following aspects

1. Inspection and installation of embedded parts

the embedded parts should be embedded during the construction of civil engineering. Before the construction of curtain wall, the embedded parts should be checked and checked according to the datum axis, center line and datum horizontal point of the project. When there is no clear requirement in the design, the operating deviation of the position and size of a piece is ± 20mm, the allowable elevation deviation of embedded parts is ± 10mm。

2. Measurement and setting out

in order to ensure that the construction of building stone curtain wall is consistent with the design drawings, and ensure the engineering quality of curtain wall installation and the coordination and tight combination of other construction units. Accurate measurement and setting out must be carried out before construction. The basis, principles and contents of measurement and setting out are as follows:

(1) basis of curtain wall setting out. According to the construction drawings, architectural drawings, structural drawings and detailed drawings of curtain walls, doors and windows, and in combination with the elevation control points given by the civil engineering unit, the location line and axis position of the curtain wall shall be accurately set out

(2) principle of curtain wall setting out. The setting out of the side face of the stone curtain wall should follow the principle of setting out from the whole to the part

(3) floor height measurement of curtain wall. Floor height measurement is the first consideration in surveying and setting out, and the basis of floor height measurement is the elevation datum point. Use a steel ruler to measure

3. Metal framework installation

(1) in order to ensure the accuracy of the installation position of the metal framework, before the installation of the metal framework, check whether the construction setting out position meets the design requirements according to the construction setting out drawing

(2) after checking the correct position of the metal skeleton, the iron parts on the fixed column can be installed for the installation of the metal skeleton

(3) when installing the metal skeleton, first install the columns in two sections of the same elevation, and then install the middle columns by pulling the line in sequence, and make the columns on the same floor installed at the same horizontal position

(4) lead the control line of each construction new year film to each installed column, carefully check it with a level, and calibrate and correct those who do not meet the requirements

(5) after the verticality of the column is checked and qualified, the metal beam of the curtain wall can be installed according to the design size. When installing traditional Chinese medicine, pay special attention to that the beam must be vertical to the column

(6) one of the columns and beams in the steel framework can be connected by bolts. If welding is used, the finished decorative surface below and adjacent to it shall be protected. Symmetrical welding shall be adopted during welding to reduce the deformation caused by welding. After the weld quality is qualified, all welding spots and welds need to go out of the welding slag and do anti rust treatment, such as painting anti rust paint

(7) after the metal framework of the curtain wall is installed, the next process can be carried out only after the concealed works are inspected and accepted by the supervision company

IV. installation of fire prevention and thermal insulation materials

v. installation of stone veneer

VI. sealant sealing

VII. Cleaning and protection

VIII. Construction precautions

summary: here is the relevant information about the construction technology of stone curtain wall. I hope this article is helpful to you. If there is anything else you don't understand, you can follow us and we will answer it for you as soon as possible
