The stone curtain wall is a form of external decoration that is often used at home and abroad. Different building structures use different types, and each construction and use is subject to different external forces. Now in order to ensure the effect of the stone curtain wall will use the stone curtain wall construction technology, the following Xiaobian simply introduced the relevant information on the stone curtain wall construction process.
First, the composition and structure of the stone curtain wall
The stone curtain wall is mainly composed of stone panels, stainless steel pendants, steel skeletons (pillars and cross braces) and embedded parts, connecting pieces and stone patch glues. However, the direct hanging curtain wall will be installed on the main structure of stainless steel pendants, do not need to set the steel skeleton, this approach requires the main structure of the wall strength is higher, preferably reinforced concrete walls, and requires the wall flatness, verticality Better, otherwise it should be skeletonized.
Second, stone wall construction process
The stone curtain wall installation and construction shall be carried out after the acceptance of the main structure of the building. For rapid and high-quality construction, the construction and design of the stone curtain wall shall be compiled. The main contents of the construction organization design include: 1. Project schedule; 2. Handling and lifting methods; 3. Measurement methods; 4. Installation method; 5, installation sequence; 6, inspection and acceptance; 7, security measures.
According to engineering practice experience, the method of stone wall installation and construction mainly includes the following aspects.
1, embedded parts inspection, installation.
The embedded parts shall be embedded in the civil engineering construction. Before the construction of the curtain wall, the embedded parts shall be inspected and checked according to the reference axis and the midline of the project and the reference horizontal point. When there is no explicit requirement for the design, a position dimension shall be used. The operating deviation is ±20mm, and the allowable deviation of the embedded part is ±10mm.
2, measuring line.
In order to ensure that the construction and design drawings of the building stone curtain wall are consistent, the construction quality of the curtain wall installation and other construction units are coordinated and tightly combined. Accurate measurements must be taken before construction. The basis, principles, and content of the measurement line are as follows:
(1) The basis for laying the curtain wall. According to the curtain wall, door and window construction drawings, architectural drawings, structural drawings, and sub-grid large sample diagrams, combined with the elevation control points given by the civil works units, the precise placement of the curtain wall position lines and axis positions.
(2) The principle of curtain line laying. The side face of the stone curtain wall should be followed by the principle of putting the line from the whole to the local.
(3) The height measurement of the curtain wall. Layer height measurement is the first problem to be considered in measuring the line-up. The basis of the height measurement is the elevation reference point. Use steel ruler to measure.
3, metal skeleton installation.
(1) In order to ensure the accuracy of the installation position of the metal skeleton, before the metal skeleton is installed, it is also checked whether the position of the construction line is in accordance with the design requirements according to the construction layout drawing.
(2) After correcting the position of the metal skeleton, it is possible to install the iron fittings on the fixed post so that the metal skeleton can be installed.
(3) When installing the metal skeleton, firstly install the two columns of the same facade, then install the middle column in the order of pulling the line, and install the same column in the same horizontal position.
(4) Lead the control lines for the construction of the new year's cards to the installed pillars, and carefully calibrate them with level gauges.
(5) After the inspection of the verticality of the column is passed, the metal beam of the curtain wall can be installed according to the design dimensions. The Chinese medicine should be installed with special attention to the beam must be kept perpendicular to the column.
(6) Posts and beams in steel frames, one may be bolted. If welding is used, finished products should be protected on the finished and adjacent finished surfaces. Symmetrical welding is used during welding to reduce distortion due to welding. After inspection of the quality of the weld, all welds and welds need to go out of the welding slag and do anti-rust treatment, such as brush anti-rust paint.
(7) After the metal skeleton of the curtain wall is installed and completed, the supervision company shall check and accept the concealed construction before carrying out the next process.
Fourth, fire prevention, insulation material installation.
Fifth, stone veneer installation.
Six, plastic injection sealing.
Seven, cleaning and protection.
Eight, construction precautions.
Summary: The relevant information on the construction process of the stone curtain wall was introduced here for everyone. I hope this article will help you. If you still have anything you don’t understand, you can follow our website and we’ll get back to you as soon as possible.
