A, paving floor tile floor
1, paving floor tile floor practice is as follows (which has waterproofing requirements of the floor, waterproofing practices refer to the indoor waterproofing construction practices)
2, construction process
(1) process:
basic level treatment → find elevation, springboard line → plastering leveling layer of mortar → spring paving control line → paving bricks → hooking, wiping seam → maintenance → skirting board installation Wipe the seam → maintenance → skirting board installation
(2) grass-roots level processing:
Clean up the debris on the concrete grass-roots level, and pick off the mortar with a burin, and use a steel wire brush to clean up the floating slurry layer. If the grass-roots level has oil stains, 10% fire alkali water should be brushed, and use water to wash out the alkali on it in time.
(3) find the elevation, bullet line:
According to the +50cm horizontal elevation line on the wall, measure down the elevation of the surface layer, and bullet on the wall.
(4) wipe the leveling layer mortar:
①Sprinkling wet:
In the cleaned grass-roots level, use a spray can to sprinkle water evenly on the ground level once.
② plaster cake and standard rib:
From the level of the surface layer has been popped under the amount of leveling layer to the skin of the elevation (surface layer elevation minus the thickness of the brick thickness and bonding layer), plaster cake spacing l.5m, plaster cake on the flat is the elevation of cement mortar screed, and then from the side of the room began to erase the standard rib (also known as punching tendon). Room with a floor drain, should be radial from all around to the direction of the floor drain to erase the standard tendon, and find a good slope. Plaster cake and standard reinforcement should use dry mortar, thickness should not be less than 2cm.
3 load file (i.e., in the standard reinforcement between the cement mortar):
Clean erase standard reinforcement of the residual slurry, paint a cement paste (water-cement ratio of 0.4 ~ 0.5) bonding layer, with the brush with the spread mortar. Then according to the elevation of the standard bar, with a small spade or wooden spatula will have been mixed cement mortar (with a ratio of 1:3 ~ 1:4) paved in the standard bar between the wooden spatula, patted with a wooden spatula, small wooden bar scraping, and then rubbed with wooden spatulas, so that its paved mortar and the standard bar to find flat, and with a large wooden bar to check the smoothness horizontally and vertically, and at the same time check whether the elevation and flooding slope is correct, watering maintenance after 24h.
(5) play paving brick control line:
When the compressive strength of leveling layer mortar reaches 1.2MPa, start on the control line of the people playing brick. In advance according to the design requirements and brick plate specification size, determine the gap width of the plate paving, when the design is not specified, tight paving gap width should not be greater than lmm, false seam paving gap width should be 5 ~ 10mm. in the room points, from the longitudinal and horizontal two directions row size, when the size is less than the whole brick multiples, will be used for the corners of the non-whole brick, transverse parallel to the doorway of the first row should be a whole brick, will be a non-whole brick row In the position against the wall, vertical (vertical doorway) should be divided in the room in the center, non-whole brick symmetrical discharge in the two wall edges. According to the determined number of bricks and the width of the seam, on the ground to play longitudinal and horizontal control lines (every 4 bricks to play a control line).
(6) laying bricks:
In order to find a good location and elevation, should start from the doorway, longitudinal first paved 2 to 3 rows of bricks, as a standard reinforcement for the longitudinal and transverse horizontal elevation line, auxiliary should be backed up from the inside to the outside of the operation, the person shall not step on the freshly paved bricks on the face of the brick, each brick should be followed by the line, the operating procedures are:
① paving before the brick slab into a half of a bucket of water in the soaked and wet, after drying When there is no bright water on the surface, it can be used.
② leveling layer on the sprinkling of water to moisten, uniformly painted plain cement paste (water-cement ratio of 0.4 ~ 0.5), do not paint too large an area, paving how many brush how much.
③ Combined layer thickness: the use of cement mortar paving, the thickness of 10 ~ 15mm.
④ Combined layer combination of materials mixing: the use of cement mortar combined with the layer, with the appropriate ratio of 1:2.5 (cement: sand) dry mortar. Should be mixed with the use of the first set before the end, to prevent the impact of bonding quality.
5 laying, the back of the brick facing up to wipe the bonding mortar, laying to have brushed a good cement slurry leveling layer, brick flute slightly above the horizontal elevation line, find the right, find the straight, find the square, with a rubber mallet to beat the solid, the order of the order from the inside back out laying to achieve the mortar is full, close to each other, solid, and the floor drain, with the abrasive wheel saw will be processed into the brick and the floor drain to coincide with the. Pave the floor tile is best to pave a room at a time, large area construction, should be taken in sections, parts of the paving.
6 dial seam, trimming: paved 2 to 3 lines, should always pull the line to check the straightness of the seam grid, such as exceeding the provisions should be immediately trimmed, the seam will be straightened, and patted with a rubber hammer. This work should be completed before the bonding layer condensation.
(7) hooking and rubbing:
Surface paving in 24h for rubbing, hooking work, and use the same variety, the same grade, the same color of cement. Selected according to the design requirements.
①Hooking: 1:1 cement mortar hooking, the depth of the seam should be 1/3 of the thickness of the brick, require the seam mortar is dense, flat, smooth. With the hook with the remaining cement mortar clear away, wipe clean.
② rubbing the seam: the requirement of straight seams, in the paving and repairing the brick layer with a slurry pot to the seam water slurry, and then dry cement sprinkled on the seam, and then rub rubbed with cotton gauze, will be full of slit rubbing. Finally wipe the cement paste on the surface layer clean.
(8) maintenance:
After 24h of paving the brick, sprinkle water to maintain, the time should not be less than 7d.
Two, fine stone concrete floor
1, fine stone concrete floor practice is as follows
2, the construction process
(1) Process:
Finding elevation, playing the level of surface layer → grass-roots level → treatment → Sprinkle water and wetting → plaster cake → plastering standard tendon → brush plain cement paste → plastering layer calendering → maintenance
(2) find elevation, play the surface level line:
according to the existing +50cm horizontal elevation line on the wall, measure the level of the ground floor layer, and then play it on the surrounding wall surface.
(3) grass-roots level treatment:
First, clean the dust, and then shovel the paste skin sticking to the grass-roots level, brush off the oil with alkaline water, and finally rinse the grass-roots level with clean water.
(4) plaster cake:
According to the surface level elevation line has been popped up, horizontal and vertical lines, with the same ratio of soybean concrete mix plaster cake, horizontal and vertical spacing of 1.5m, the elevation on the gray cake is the surface elevation.
(5) erase the standard bar:
The larger area of the room in order to ensure the flatness of the room floor, but also to do the standard bar (or called punching bar), to do a good job of the gray cake as a standard erase bar standard bar, with a ruler to scrape the flat, as a pouring of fine gravel concrete thickness of the surface layer of the standard.
(6) brush plain cement paste combined layer:
Before laying the fine stone concrete surface layer, in the wet grass-roots level on the brush a 1:0.4 ~ 0.5 (cement: water) plain cement paste, do not brush the area is too large, with the brush with the paving of fine stone concrete, to avoid a long time the cement paste drying lead to the surface layer of hollow drum.
(7) wipe the surface layer, calendaring:
①When the surface layer of gray surface water absorption, with a wooden spatula rubbing, smoothing, dry cement sand mix and fine stone concrete slurry mix, so that the surface layer to achieve the combination of tight.
②The first smoothing: use the iron trowel to gently smoothing again until the slurry.
③ second wipe: when the surface layer of mortar after the initial set, the ground surface layer on the footprints but walk up to not sink, with an iron trowel for the second wipe, the pits, sand holes filled and smoothed, pay attention to the pressure shall not be missed.
④Third smoothing: when the surface mortar before the final set, that is, people step on slightly footprints, with iron spatula calendaring no smudging, can be used to smudge the iron spatula for the third time calendaring, this time to smudge, smudging all smudging texture flattening and calendaring to achieve the surface of the surface of the layer of dense and smooth.
(8) Maintenance:
The surface layer will be watered and maintained after 24h of smoothing, not less than 2 times a day, and the maintenance time is at least 7d (the room should be closed for maintenance period).
