[0040] 1. The old cellar roof has a large slope, and the old cellar pool roof is strictly prohibited from using fire. The waterproof layer is made of SBS self-adhesive waterproof roll material. The SBS self-adhesive waterproof roll material effectively bonds with the base layer, and also avoids the sliding of the rigid layer.
[0041] 2. Base treatment: The base should be clean, solid, flat, and clean. The male and female corners, pipe roots, etc. at the intersection of the plane and the vertical surface should be rounded with a radius of 50 mm.
[0042] 3. During construction, first perform the line release, and then perform the paving according to the position of the bonding and overlapping lines of the roll material. Tear off the release film while paving to ensure tight bonding.
[0043] 4. General additional reinforcement treatment of details: The additional layer is made of double-sided self-adhesive waterproof roll material. The additional layer roll material and standard prefabricated parts are used for additional reinforcement treatment at two-sided corners, three-sided male and female corners, etc., and the plane and vertical surface are evenly expanded. The method is to cut the roll material according to the shape of the details, and then paste it on one side. After checking the size and shape, the cut roll material is pasted on the base surface. The additional layer requires no air pockets and is compactly paved.
[0044] 5. Large-area roll material paving: On the treated base surface, the reference line of the paving roll material is marked according to the width of the selected roll material, and the overlapping seam size is 100 mm long and 100 mm wide. The reference line is used as the basis for roll material paving construction. When the weather temperature is low, hot air heating or asphalt coating can be used for auxiliary overlapping.
[0045] 6, paving while checking, found that the overlap is not real time repair, do not leave any hidden, site construction, quality inspectors must follow the inspection, inspection and experience collection qualified report to the general package, supervision and construction in accordance with the relevant engineering quality acceptance specification and approved construction scheme for acceptance, acceptance after the timely construction of the protective layer.
[0046] Rigid layer construction:
[0047] 1, laying steel bar net:
[0048] 1 steel production: steel must be straightened, rust removal, clean oil. On the level of netting steel, both ends should be bent hook.
[0049] 2 steel protection layer: in the intersection of the steel bar net has been formed, set 30X30X15hmm with lead wire cement mortar prefabricated block, spacing with 600X600mm is appropriate this size should be the multiple of the steel spacing and cross pad block, Meihua mortar pad should be tied firmly with steel bar net, to meet the concrete surface protection layer three 10mm requirements.
[0050] 2, installation of grid and edge form
[0051] 1 according to the pop out of the grid line and the edge line installation of grid and edge form, should be set firmly, angle line straightening.
[0052] 2 formwork and grid should have enough stiffness, smooth surface, the surface should be coated with a layer of release agent before installation.
[0053] 3 grid processing into the inverted trapezoidal, the upper wide 30mm, the lower wide 20mm.
[0054] 3, simple frame
[0055] Before pouring concrete should be simple frame, as a pedestrian access and transportation channel, strictly prohibited to step on the installation of steel bar net and formwork.
[0056] 4, pouring concrete
[0057] Waterproof layer of concrete pouring according to the grid seam warehouse, each warehouse of concrete must be continuous pouring, no construction joints are allowed, the pouring of concrete according to the principle of first far, then near, first high, then low.
[0058] 5, the concrete pouring should be hit flat, and with a flat vibrator.
[0059] Small tile construction:
[0060] 1, the process flow is: base inspection → paving preparation → after the small tile roof ridge tile → small tile → water line → inspection → cleaning.
[0061] 2. The laying sequence should follow left to right and bottom to top to avoid inconvenience during installation. Incorrect installation sequence can easily break the tiles, causing problems. Before laying the roof tiles, preparatory work should be done in conjunction with the ridgeline, which is a key difference between small blue tile installation and other installation methods. Installation can proceed by laying the small blue tiles sequentially along one gable wall to the next; or by stacking the small blue tiles in advance and laying them outwards according to the installation requirements, starting from the gable wall and working outwards; alternatively, a stack of tiles can be placed on each side of the gable wall as end caps, and then the small blue tiles can be laid symmetrically from both sides towards the center.
[0062] 3. Before constructing the tiled roof, the roof should be divided into central sections, with each individual roof section as a unit. The central section should be divided into 120mm and 240mm sections on each side. For the eaves, lines should be drawn for each individual roof section, and the eaves should be marked on the gable walls according to the tile specifications. When marking the central sections, the eaves ridges of the front and rear roofs must be on the same parallel line.
[0063] 4. Ridge construction: A structure is built along the bend of the roof or the wall, as part of the ancient architectural style. It is mainly composed of tiles and mortar, and plays a role in waterproofing and aesthetics during construction.
[0064] 5. When laying the roof tiles, proceed from right to left according to the ink lines. Before starting, locate and mark the horizontal points of the eaves, ridge, and rafters. Extend the drip tiles outwards by 20mm. The eaves tiles should extend downwards and outwards by 150mm; the narrow end of the second tile should also face downwards. Continue laying the tiles from bottom to top. The tiles must be laid straight and not crooked. The height and straightness of the ridge tiles should be coordinated with the mortar application, ensuring tight and airtight joints to prevent drafts.
[0065] 6. During the construction of overlapping tiles on the roof of ancient buildings, the tiles must be placed straight, with the tile flanges aligned with the line, and close contact between the tiles to enhance the adhesion between the tiles and the mortar, thereby increasing the waterproofing of the tile surface. The tightness of the tiles must be kept consistent, otherwise, skewing will occur. When the tiles reach the ridge, the supporting tiles should be removed promptly, mortar should be applied, and then the tiles should be inserted.
[0066] 7. When two buildings are adjacent and connected, the junction is also called a gutter. Waterproofing at the gutter location mostly uses a plaster-backed method. Sloping gutter roofing occurs at the intersection of slopes in different directions. During construction at this location, drip tiles are installed first at the eaves. When laying the tiles, the larger end of the first tile faces down, and the smaller end of the subsequent tiles faces down. Mortar is used at the bottom to increase adhesion, and the tiles must be firmly bonded. Medium-strength mortar is used for joint sealing, and it must not allow draft.
[0067] Firewall construction:
[0068] The wall material is old green brick, and the masonry form is: hollow brick masonry.
[0069] 1. Construction process: acceptance of masonry foundation or lower structure → setting out of upper part of base wall → laying bottom → cornering of wall → cornering and stringing of vertical rod structure → construction of masonry base wall → pointing and leveling → construction acceptance.
[0070] 2. Brick inner and outer wall laying: according to the number of courses and bays required in the architectural design drawings, start laying bricks from the intersection corners or joint corners of the inner and outer walls, and lay bricks to one side, and the inner and outer walls should be laid alternately, and the vertical and horizontal directions should be staggered and connected. Before starting to build the hollow wall, the brick laying test should be done in advance, and if the bricks are not uniform, an additional brick can be added to the hollow wall, but the bricks should not be cut.
[0071] 3. Brick laying: full-cut plastering method should be used for building hollow walls. In all the hollow walls, except for the two ends, no mortar should be used in the contact between the base bricks and the bricks. The hollows in the hollow walls should not be backfilled with mortar, and vertical cracks should not appear between the walls. The concrete should be watered 1-2 days in advance to keep it dry.
[0072] 4. The thickness of vertical and horizontal mortar joints and the width of vertical mortar joints should be controlled at about 10mm, but the width should not be less than 8mm and not more than 12mm, and the lines between the mortar joints should always be horizontal and vertical.
[0073] 5. The mortar filling of horizontal joints should be full, and the amount of mortar used for vertical joints should be appropriate, and cement mortar should not be used for filling, and transparent mortar joints should not be left, and alkaline cement or cement mortar should not be used directly for filling.
[0074] 6. The brick joints of hollow walls should be embedded with lime jointing agent. The masonry construction technology is: first, use the jointing agent to evenly coat and compact the brick joints along the horizontal and vertical lines, use the jointing hook to press the brick joints into a round light, form an eight-character joint, the depth of the eight-character groove is about 10-12mm, and the joint edges should be clear; then clean the dust and debris on the bricks thoroughly.
[0075] Plastering construction:
[0076] 1. First, mix ordinary lime with purple bamboo and rice straw fibers, then put them in a stone mortar and beat them until they are tough, and then use them.
[0077] 2, with steel, copper wire, square nail, etc. according to the shape of the fixed main skeleton, with steel reinforcement good basic contour, then gradually piled up, electric white plastic, complete the initial blank; with tooth feet will be piled up surface pressure solid, smooth, and draw out the line patterns; after painting fill color, the whole lime plastic complete.
[0078] 3, can choose to brush glue alum water reinforcement or using other high polymer material protection, avoid lime plastic color in light, ultraviolet radiation, etc. fade.
[0079] 4, before the plaster completely dry, avoid touching and moving, to avoid damage to the work.
