Preparation before installation of marble windowsill
1. Marble windowsill: stone windowsill.
2. The variety, material and color of the marble windowsill should be selected according to the design. Wood products should be dry, the moisture content should be controlled within 65438 02%, and they should be treated with anticorrosion, and deformation is not allowed.
3. The general bracket or hanger is made of angle steel or flat steel for installation and fixation; Generally, the structure of marble windowsill board is directly installed on the whisker surface of the wall under the window and stabilized with mortar or fine stone concrete.
Main tools for installing marble windowsill
1. Power tools: electric welding machine, electric stone saw, hand drill.
2. Hand tools: large planer, small planer, small saw, hammer, angle cutting ruler, rubber hammer, ruler board, No.20 lead wire and small iron wire, molten iron level, box ruler and screwdriver.
Installation conditions of marble windowsill
1, marble windowsill is installed under the window wall, and the structural construction should be based on the selection of windowsill varieties, and wooden bricks or iron pieces should be embedded. 2. When the length of the windowsill is greater than 1500mm, in addition to placing wooden bricks or iron pieces at both ends of the window, 3 water bricks or iron pieces should be added every 500mm. The transonic window sill plate shall be provided with a fixed bracket according to the design requirements.
3, the installation of marble windowsill board must be carried out after the window frame installation. If the windowsill board is connected, it should be done after the decoration layer of the wall and the ground is completed.
Installation technology of marble windowsill
1. Positioning marking: according to the elevation and position of the lower window frame required by the design, mark the elevation and position line of the window sill.
2. Check the embedded parts: After positioning and marking, check whether the embedded parts in the installation position of the windowsill board meet the connection structure requirements of design and installation, and correct any errors.
3. Bracket installation: When the windowsill bracket is needed structurally, the embedded parts of the fixed bracket should be checked before installation, and the bracket should be installed according to the designed structure after confirming the correct elevation and position.
4. Installation of marble windowsill board: find a good position according to the design requirements, pre-install, meet the requirements in elevation, position and wall size, and the joints are smooth and tight. After the fasteners are correct, they will be formally fixed and installed according to their structural fixing methods.
Precautions for installation of marble windowsill
1. Marble window sill plate cannot be inserted into the cap groove under the window. Before construction, the installation of windowsill board should be checked. During construction, it should be pre-installed and fixed after meeting the requirements.
2. The bottom pad of the windowsill board is not firm: the ash is not tightly screwed; The leveling strips of wooden and metal windowsills are inconsistent, and the elevation is uneven; During construction, each working procedure shall be carefully completed and leveled. Pad, tighten and fix firmly. Brackets should be installed across the empty windowsill board to make the brackets bear uniform force.
3. Pay attention to the unevenness and straightness of several spliced windowsills, and the length and width deviation and thickness of the processed windowsill are inconsistent. Attention should be paid to using the same specification in the same part during construction.
