Several points for attention in KTV decoration construction

I believe many people like to go to ktv. If you look at ktv carefully, you will find that the decoration of ktv is really not very simple, and the exposed walls and other equipment look very complicated, involving a lot of complicated decoration knowledge. Let's take a look at some matters needing attention in KTV decoration construction.

A, KTV decoration construction matters needing attention

1, to avoid the quality problems of KTV decoration and construction.

(1) ground elevation, generally in the bathroom, washroom, bathroom, etc. Mainly because the floor epithelial standard is too high; The waterproof layer is too thick; If the pressure felt concrete is too thick, the floor elevation should be carefully checked during construction, and the thickness of each construction should be strictly controlled to prevent it from exceeding the height.

(2) The flooding is too small or the local slope is reversed, the installation elevation of the floor drain is too high, the basic treatment is uneven, and there are pits, resulting in local water accumulation; Poor slope finding at the grass-roots level leads to too small or inverted slope.

(3) The ground is uneven, there is a small height, the thickness of bricks is inconsistent, there is no strict selection, or the brick surface is uneven, or there is no leveling and compaction when paving, or there are too many people, which is not conducive to maintenance. To solve this problem, we must first choose the right brick, and the substandard and irregular bricks must not be used.

(4) kicking and hollowing on the surface,

The main reasons for the hollowing of the surface layer are that the grass-roots are not clean, water is not permeable and early dehydration is caused. The master here was premature, and bonding mortar failed to reach the strength and was vibrated by external force, so that the block and the bonding layer were separated into empty drums. (5) When the black edge is less than the whole brick, mortar shall be used to repair it, instead of cutting half a block or small strips to form a black edge, which will affect the impression. The solution is to cut and lay bricks according to the rules.

2. Protection of finished KTV decoration products

(1) The completed project should be well protected, such as the door frame and door bolt should be nailed to protect the iron sheet to prevent knocking; Materials should be transported in narrow trucks to reduce collisions, and feet should be wrapped in rubber, plastic or cloth.

(2) When cutting bricks, the following boards should be padded.

(3) When working on the surface of the paved cylinder brick or cement brick, it is forbidden to throw heavy objects such as steel and iron pieces on the ground.

(3) It is forbidden to pollute the surface during the construction of paint slurry.

3. Building safety

(1) When using the portable electric cutting machine, the grounding wire and the leakage protection switch should be connected, and the trial operation should be carried out before use.

Only after passing the inspection can it be operated. (2) When working in the dark at night and expanding construction, 36V low-voltage running lights should be used for lighting.

(3) When the derrick and double cages are used for vertical transportation, the loading and unloading signals should be contacted, and the loading and unloading operations can be carried out only after the cages are balanced.

Second, the wall tile technology

1, process

Grass-roots treatment → hanging vertically, setting square, finding rules → pasting ash cake → plastering bottom mortar → elastic line framing → arranging bricks → soaking bricks → tiling bricks → jointing and wiping the joints of face bricks.

2, concrete wall operation method

(1) Basic treatment: wall leveling, steel brushing, watering and wetting.

(2) Hang vertically, set square, find rules and paste ash cakes: according to the specifications and sizes of ceramic tiles, make ash cakes at fixed points.

(3) Wipe the bottom mortar, brush a layer of 107 glue cement slurry, add 10% water, wipe the bottom mortar, and water it for maintenance the next day.

(4) The elastic lines are arranged in rows of bricks.

(5) soaking bricks, inlaying decorative tiles,

(6) Tile jointing and seam wiping

Third, the floor tile project

1, clean up the grassroots and find the law.

Clean up the base, and the surface mortar skin should be shoveled and swept clean.

Clean the mortar dirt on the concrete floor. 2. Sweep plain cement slurry together

On the cleaned base, thoroughly water it, sprinkle it with plain cement, and then sweep it evenly with a broom. The size of the pulp sweeping area should be determined according to the speed of priming and spreading ash, and it should be spread with sweeping.

3, around the room from +50cm below the horizontal line screed to the bottom gray epithelial elevation, paste the ash cake.

4, file, floor tile

Check the clearance size of the laid room, find a good square, and pop up the founder vertical control line on the leveling layer. When laying floor tiles, the dimensions should be arranged in the vertical and horizontal directions of the room, and the joint width should not be greater than 1cm. When the size is less than the multiple of the whole block, you can cut half a brick for the corner.

Fourth, the wooden sound-absorbing board wall construction technology

1, keel

During wall construction, the keel should be installed according to the design and construction drawing, and the keel should be leveled. The keel surface should be smooth and level, without corrosion and deformation. The arrangement size of the keel must adapt to the arrangement of the sound-absorbing board.

The wooden keel spacing should be less than 300mm, and the light steel keel spacing should be no more than 400 mm, and the installation of the keel should be perpendicular to the length direction of the sound-absorbing board. 2. Install sound-absorbing board

The sound-absorbing board follows the principle from left to right and from bottom to top; The gap is upward; When installed vertically, the notch is on the right side; If some solid wood sound-absorbing boards have requirements for patterns, each facade should be installed from small to large according to the pre-programmed numbers on the sound-absorbing boards.

3. Fixation of sound-absorbing board on keel

(1) Wooden keel is installed with nail. The sound-absorbing board is fixed on the keel at the tongue and groove with nail, and the nail must be 2/3? The above-mentioned embedded wooden keels shall be evenly distributed and have a certain density, and the number of nails connected with each sound-absorbing board and each keel shall not be less than 10? A.

Construction procedure for pasting foamed wallpaper: draw vertical lines → cut paper → seal water → brush glue → paper wall → seam → catch up with bedding face → arrange paper seams → brush glue face.

2, wallpaper construction technology

(1) When drawing vertical lines, wait for the primer to dry before drawing vertical lines. The starting position should start from the internal corner of the wall and be smaller than the wallpaper 1 ~ 2 cm.

(2) Paper-cutting: This process is very important and directly affects the quality of wall pasting.

Stuffy water: Foamed plastic wallpaper can expand to about 1cm after absorbing water. If the dry wallpaper is put on the wall immediately after painting, there will be many wrinkles and it will not survive. So first soak the foamed wallpaper in the sink, shake off the excess water after taking it out of the sink, and let it stand for 20 minutes to fully expand the wallpaper.

(4) Glue-brushing: Glue-brushing on the back of the wall and wallpaper at the same time.

(5) Sticking: It is the most important process in the wallpaper pasting project, which directly determines the quality of the wall.

3, local repair method (after waiting for paper wall glue dry)

(1) paper edge "opening": due to uneven gluing or premature drying of glue solution, it can be re-glued and compacted after gluing.

(2) There are bubbles on the paper: We can use our paper cutter to cut the bubbles, squeeze out gas or excess glue, and then flatten and compact them. (3) Stubble exposed at the joint: If stubble exposed at the joint is caused by drying shrinkage, latex paint can be used to find color.

(4) Wrinkles appear on the paper surface: the paper web can be lifted and pasted again before the adhesive is dry.

(5) Wallpaper damaged by collision: lines and colors can be hollowed out and filled, and patterns, patterns and gaps should be matched.
