1. There are many types of work: civil engineering, water supply and drainage, heating and ventilation, air conditioning, strong and weak electricity, communication, fire fighting, decoration, curtain wall, windows, etc. all enter the site almost at the same time, so it is difficult to arrange assembly line operation. Lobby and corridor are the only places for all types of work, and the lofting, construction, inspection, debugging and renovation of all types of work will affect the dry hanging of marble and the paving and maintenance of the ground. Measures and plans must be taken during construction.
2. There are many suspended ceilings: the suspended ceilings in general star-rated hotels are large in area and complex in shape, and the acceptance of concealed works is a major feature of construction. There are many links and departments in the overall test and acceptance of water, electricity, fire fighting, spraying and other equipment in the suspended ceiling, which affects the flow operation of the project. To deal with these problems, corresponding measures should be taken.
3. There is a lot of stone work: floor paving, stair paving, wall surface, cylindrical dry hanging, kicking, edging, arc plate and so on. In terms of types, there are: marble, granite and artificial stone, microcrystalline stone, etc.
1. Construction deployment
1. Excellent management personnel and on-site daily management team are selected, and the positions of personnel are clearly defined.
2. Provide enough skilled workers: carpenters, oilers, bricklayers, electricians, hydraulic workers, wallpaper workers, coolies and security guards.
3. The machines and tools are well equipped.
second, the construction process
because the hotel decoration project has a guest room part and a public part, according to the construction characteristics, considering the difficulty of decoration, the supply of materials and the sequence of personnel entering the site, it is appropriate to carry out the construction in different areas. In order to complete the decoration project with high quality and high efficiency in the case of shortening the construction period, reducing logistics and reducing labor, managers at all levels and professional foremen need to unify their thinking and coordinate their pace, carefully arrange the reasonable interpenetration of working procedures, have foresight in staffing, materials and tool plans, and strive to control the quality, construction period and materials.
General principles of engineering decoration sequence:
1. Base course first, then facing;
2. Go up first and then down (that is, the wall body and the ground are born with flowers);
3. Pipeline (water and electricity) before sanitary ware and lamps;
4. The furniture is centrally processed off-site;
5. Work that is easy to be defiled or difficult to protect, such as wallpaper, carpet and glass, shall be arranged later as far as possible.
III. Preparation before entering the site
1. Before construction, we should fully determine the construction drawings and main material samples with the owner, and organize drawing study and joint review to lay a foundation for the smooth decoration project.
2. Before construction, make a detailed material plan according to the engineering quantity, and complete the ordering of main materials according to the capital and project progress.
3. The management personnel are stationed at the site.
4. Make arrangements for temporary water and electricity facilities and site on the construction site, so as to facilitate the smooth construction.
5. Arrange workers' meals, accommodation and transportation.
6. Purchase the bulk materials and appliances needed in the preliminary project.
7. The first batch of workers arrived: electricians, welders, carpenters, hydraulics, storehouses, bricklayers, coolies, security guards, etc.
8. handle all the procedures for local construction permission and the registration procedures for workers.
9. Materials enter the site.
11. The second batch of workers enter the site: carpenters, hydraulic workers, electricians, bricklayers, coolies, oilers and wallpaper workers.
iv. wallpaper pasting technology
1. construction sequence: clean the wall without hollowing, brush the bottom oil, scrape the putty, and polish and seal the wallpaper with glue for generations, and post it clockwise to cut the seam.
2. Precautions: both the wall and the back of the paper must be painted with glue, which is thin and uniform, without binding edges. After the back of the paper is painted with glue, the glue surface and the glue surface should be overlapped to avoid the glue drying quickly and facilitate the wall mounting. After brushing glue for 5-11mm, it will swell by 1.5%-1.8%, shrink by 1.2%-1.8% after drying, and naturally tighten after drying. The first wallpaper should be posted with elastic lines, and the length of mosaic should be paid attention to when cutting paper, leaving enough margin.
V. Construction of wall and floor tiles
1. Construction sequence: The wall area is being inspected, and the grass-roots treatment line is selected to soak and stick bricks to wipe joints.
2. Precautions: The base course must be firm, flat, square, vertical and free from hollowing, and the reserved parts should be chiseled in advance. Choose bricks carefully, the color should be consistent, and the pattern should find the right splicing direction. The corners shall be cut neatly, and the sides shall be pressed against the front, avoiding the line of sight. The jointing cement shall be dense and lower than the brick plane, and the upper, lower, left and right sides shall be smooth. No bulge or deflection. Corner founder, seam in advance, elastic line, patched brick should be greater than or equal to 51mm, and cut brick up and down not less than half a brick.
VI. Stone paving construction
1. Stone paving on the ground: Before construction, the concrete cushion should be cleaned and wetted with water. If the cushion is found to be empty, it should be pried over and the empty part should be leveled again; Anti-seepage treatment should be done at the bottom of white marble on the ground.
2. Construction method:
① According to the site test of the construction drawings, be familiar with various parts, sizes and practices, and find out the relationship between the edges and corners of the hole.
(2) Trial arrangement and trial spelling: before laying, try spelling the stone plates in different places according to the pattern color and texture, and arrange them in two directions by numbers, and then put them in order according to the numbers. In two mutually perpendicular directions indoors, spread two pieces of dry sand, the width of which is greater than that of the plates, and the thickness is not less than 3cm, and arrange the plates according to the drawings, so as to check the gaps between the plates and check the relationship between the plates and the walls and column holes.
③ according to the test arrangement results, control the crosshairs perpendicular to each other in the main parts to control the position.
(4) before paving, clean the cushion layer, sprinkle water to wet it, sweep the pro-cement slurry, determine the thickness of the ground bonding layer according to the horizontal line, and pull the crosshair to lay the bonding layer (generally using 1: 4 hard cement mortar), then spread it from the inside to the door, and pat it for leveling.
⑤ The stone slabs should be laid from inside to outside, and numbered according to the trial spelling. When placed, the four corners will fall at the same time, and the slabs will be hammered with a rubber, leveled with a spirit level, lifted after correction, and poured with cement slurry and installed in place. After paving the first block, it shall be laid in sequence to both sides and backward direction. When gaps are found, plates shall be lifted, mortar shall be filled before installation, and joints between plates shall be strict, generally leaving no gaps.
⑥ after paving for 1-2 days and nights, tick off the seam, select mineral pigments with similar colors to the stone and mix them with cement evenly to prepare cement paste, tick off the seam with a tick-off chisel, and then clean it with cotton yarn.
3. Quality requirements:
① Bonding with the base should be firm, without hollowing.
② the surface is neat, the color is consistent, the seams are straight, and the patterns are naturally spliced.
③ The edges and corners of the plate are square, and there are no cracks, cracks and corners.
4. Allowable deviation:
① The allowable deviation of surface flatness is 1mm, and it shall be checked with a 2-meter ruler.
(2) The allowable deviation of seam flatness is 2mm, and 5 meters shall be pulled for inspection, which is less than 5 Milla sideline.
(3) joint height difference is not more than 1.5mm ..
(4) plate gap width is not greater than 1mm when there is no requirement in the design.
VII. Stair engineering construction:
① Stair handrails should be installed on the stair wall, step facing, metal railings and wall handrails after passing the inspection. Wooden handrails should be made and installed by setting out in situ according to the design requirements and the actual situation on site. The elbow of the handrail should be an integral elbow. The groove depth at the bottom of the handrail is 3-4mm, and the width is the same as that of the flat iron. The installation of the handrail should be carried out from bottom to top. First, the starting elbow should be equipped according to the slope of the column, and then the handrail should be connected. The joint should be anchored by dark tenon or iron, and bonded with glue, and the end should be connected with the wall and column with flat iron.
(2) metal stair railings and handrails shall be installed according to the design requirements, and the installation spacing position of railing uprights shall pop up. The uprights at both ends of the stair starting point and platform should be installed first, and then the other uprights should be installed by the same method. Handrails shall be installed by welding, starting from the starting elbow and then connecting with straight handrails. The interface shall be cut correctly according to the required angle and filed flat. When installing, the starting elbow shall be fixed by spot welding with railing uprights, and welding can be carried out only after the elbow is installed. After the elbow is installed, the uprights at both ends of the handrail shall be temporarily fixed by spot welding, and at the same time, one end of the straight handrail shall be butted with the elbow and fixed by spot welding. Then, the handrail shall be fixed by spot welding with each upright, and welded and polished formally after passing the inspection.
VIII. Carpet paving
1. Construction sequence: floor cleaning, peripheral nailing, smooth laying of primer, hot stitching and cleaning.
2. Precautions in construction: The floor must be flat and dry, and the carpet should be spliced with grain, color and shading. Use flat-fell seam ironing belt to connect the edges, and the surrounding nails are firm and evenly distributed. The joint of the wall is even, and there is no wave. The door is located in the middle of the crack of the door, and there is no gap from the outside. The blank holder is firm and tidy. The fluff should be straightened out. Keep it clean and free of oil stains and other sundries.
