★ ★ strong and weak: home appliances in the strong refers to the voltage 220 volt electrical lines, usually connected to lights, switches and sockets, for the total supply of electrical appliances. Weak electricity refers to network lines, telephone lines, cable television lines, speaker cables, and other currents with small currents. Generally, strong and weak wires cannot take a wire tube, and they cannot even run next to each other with a 6-cm spacing.
★ ★ design drawings: design drawings, sub-plans, floor plans, ceiling plans, elevations, node large sample plans, strong laying plans, weak laying plans. The floor plan is a hypothetical room with no ceilings. From above it overlooks the drawings of all room furniture layouts. The standard floor plan shows the dimensions, location distribution of all furniture and major appliances, and the location and dimensioning of all walls, windows, and doors in the room. The ground plan is also called the floor laying diagram, indicating the size, height, position, laying angle and name of the bricks or floors used in the rooms. The ceiling plan is similar to the plan, but it reflects the installation of ceilings and lights on the ceiling. The elevation view is assumed to look horizontally from one point of the room to one direction, and the position and size of the furniture and appliances seen. The large sample plot draws its internal structure and construction process for a specific construction object. Look at other names to know what it is.
★★ Clear water and mixed water: When painting wooden furniture surfaces, keep the wood color as clear water, and cover the color of the paint into mixed water. Each has its own advantages and there is no difference between good and bad.
★ ★ 45 degree grinding brick: At the corner of the kitchen or bathroom, the edge of the tile will be polished 45 poison angle. In the form of /||, it is much better than using the angle of the sun. But ... the final effect still depends on the master's skill...
★ ★ Bracket installation method: If the bathroom is used under the counter basin, the bracket is used to fix the basin instead of sticking to the marble countertop. Avoid knocking marble when it needs to be replaced for some reason.
★ ★ playing keel: ceiling, floor, wall, door, etc. have a certain degree of thickness when the large plane needs this process, the specific use of wood, light steel and other materials, with a shot or wood nails crisscross The grid-like brackets with the same spacing are laid on the floor, gypsum board, wood board, etc., which are light, smooth, and save materials.
★ ★ open trunking / dark line / dark pipe: open trunking: also called dark line. Use a cutting machine or other tool to make XXmm thick grooves in the wall and bury the wires and pipes in the inside so that the lines are not visible outside the walls and they look beautiful. It is generally required that the trunk be horizontal and vertical without slashes. Dark line: The strong/weak wire buried in the wire slot is usually wrapped in a wire tube. The rules for the use of strong electricity are 1.5 mm2 insulated copper wire for cross-sections of lighting wires, 2.5 mm2 insulated copper wire for ordinary sockets, and 4 squares for air-conditioned wires. Otherwise, when using air conditioners, it is prone to overheating and softening. The best use of cooked glue line, strong corrosion resistance. The wire tube generally uses 4 points PVC pipe on it. Underdrain: buried pipes/pipes in the in-line tank. There are many types (I hope TX will add it in detail. I know PPR tube, galvanized tube...)
★★Batch wall: Scoop out some unnecessary objects on the wall, such as protruding concrete or previously painted latex paint, to keep the wall clean. Usually before brushing putty. Some places are accustomed to brushing putty steps in the batch wall.
★★ Brush putty: Brush the putty on the wall to ensure the smooth construction of the wall. The batch is generally approved three times, dried and sanded to form a smooth surface. This step is performed before the latex paint.
★ ★ spray and roller: two methods of latex paint construction. Spraying is to install latex paint in a special sprayer and spray it on the wall. The method is simple in operation, has large pollution during construction, and is very wasteful of latex paint, but the effect is very good. Roller coating is a traditional process. The latex paint is applied on the wall with a long rod with a hair shaft to save the latex paint. There is no pollution in the construction, but the final effect depends on the master craftsmanship.
