Detailed Description

As illustrated in fig. 1, a roofing stone flashing structure, including the roof, parapet 1, waterproof coiled material 3 is laid at roof upside and parapet 1 inboard, lay the isolation layer on waterproof coiled material 3, establish the waterproof protective layer on the isolation layer, establish the cement mortar layer on the waterproof protective layer, establish concrete area 4 above the cement mortar layer concrete area 4 be the inclined plane form, establish grout layer 5 at concrete area 4 upper surface, establish cement mortar anchor coat 6 on grout layer 5, establish plain lime plaster layer 7 on cement mortar anchor coat 6, establish the stone material sheet layer above plain lime plaster layer 7, at handing-over department of adjacent stone material sheet layer, the handing-over department of stone material sheet layer and parapet to and establish resistant sealed glue 2 of waiting in the gap of stone material sheet layer and roof handing-over department.

The waterproof coiled material on one side of the parapet wall is 250mm higher than the roof, the head of the waterproof coiled material is fixed on the parapet wall by a metal batten nail, and a sealing material is arranged at the interface.

The isolation layer is a 0.4mm thick polyethylene film or a waterproof coiled material.

The stone slab layer comprises three parts, namely a vertical plate 10 combined with the parapet, an inclined plate 9 combined with the concrete area, and a flat plate 8, wherein the vertical plate 10 is parallel to the parapet, the flat plate 8 is parallel to the roof, and the inclined plate 9 is in a slope shape. The thickness of the waterproof protective layer is 5-7 mm. The thickness of the plaster layer 7 is 2 mm. The cement mortar bonding layer 6 is 25 mm-35 mm.

The construction process comprises the following steps:

1. the waterproof coiled material is paved according to the design requirement, the height of the coiled material at the flashing part of the parapet wall is larger than 250mm, the head of the coiled material is fixed by a metal pressing strip nail, and the coiled material is sealed by a sealing material.

2. Before the stone is paved, a polyethylene film with the thickness of 0.4mm is adhered on the coiled material or a layer of coiled material is paved dry to be used as an isolating layer.

3. Setting a waterproof protective layer: the cement mortar is mixed with the binder, evenly coated on the isolation layer, watered and maintained after final setting until the cement mortar has higher strength. Cement mortar is adopted for plastering to form a cement mortar layer with the thickness of 5-7 mm, a concrete area with splayed corners is plastered by fine aggregate concrete above the cement mortar layer, and the surface is rubbed and rubbed with hair by a wood trowel.

4. And popping up three positioning lines of the stone waterproof protective layer on the waterproof protective layer according to the roof slope. The highest point of the roof is used as a standard, a horizontal line is shot upwards at positions 100mm and 250mm respectively, a horizontal line is shot outwards at positions 250mm from the parapet wall, and the stone is guaranteed to be accurately installed.

5. And processing the unit plates of the stone plate layer according to the actual situation on site.

6. The stone slabs need to be blanked according to a blanking drawing, and in order to ensure the consistency of patterns and colors of the stones, each outgoing stone must be numbered. The upper edge of the opposite face stone and the outer edge of the plane stone are processed into circular arcs during processing, so that collision and damage are prevented. And after the processing is finished, coating stone protective liquid on six exposed surfaces of the stone.

7. Stone slab layer made of granite is paved and adhered to flashing

(1) Before paving and pasting, cleaning sundries on the surface of the base layer, brushing the sundries with a steel wire brush, removing adhesive substances such as mortar and the like on the base layer with a chisel, cleaning the adhesive substances, and watering and wetting the base layer one day before paving and pasting.

(2) When the mortar is paved, a spraying pot is used for wetting the base layer, a layer of cement paste with the water-cement ratio of 0.4-0.5 is brushed, the brushing area is not too large, and the mortar is paved along with brushing.

(3) The bonding layer is made of 1:2 or 1:3 cement mortar and cement mortar with the consistency of 25 mm-35 mm, the cement mortar is uniformly mixed by a mortar mixer, the water adding amount is strictly controlled, the mixed mortar is held by hand to form a cluster, the cluster is preferably held by hand or is scattered by hand, and the thickness of the mortar is controlled to be 1 mm-3 mm higher than the top surface elevation of the ground when the plate is placed on the bonding layer. After paving, the materials are stricken off by a strickle, and then are compacted and smoothed by a trowel, so that the paving area is not too large.

(4) According to the layout, the stone materials are symmetrically laid from the highest point of each surface to two sides, after 3-4 units of the stone materials on the plane and the outer edge vertical surface are laid and attached, the inclined plane stone materials are laid and attached upwards, and after the inclined plane stone materials are finished, the upper vertical surface stone materials are laid and attached at intervals of not less than 12 hours.

(5) Laying in a trial mode: and (3) moving the stone plate to align with the longitudinal and transverse control lines, horizontally placing the stone plate on the paved dry and hard mortar binding layer, knocking the top surface of the stone plate or knocking a wood base plate on the stone plate by using a rubber hammer, after the mortar is compacted to the paving height, lifting and moving the stone plate aside, checking whether the surface of the mortar is completely matched with the stone plate or not, if a void is found, filling the mortar, and then paving and pasting the stone plate formally.

(6) And (3) formal paving: uniformly scraping 2 mm-thick plaster on the back of the stone plate, aligning the stone plate to the paving position to enable the periphery of the plate to fall down simultaneously, tapping the stone plate or a wood cushion block by using a rubber hammer to enable the stone plate to be flat and solid, checking the flatness of the stone plate according to a horizontal line and a horizontal ruler, and reserving a gap with the width of 8-10mm between every two stone plates.

8. Waxing

When the compressive strength of the cement mortar combined layer reaches 1.2Mpa, after each process is finished, the surface of the surface layer is cleaned by oxalic acid or clear water, dried, wiped clean, dipped with finished wax by cloth or clean hemp silk and thinly and uniformly coated on the surface of the stone plate. After the wax is dried, the oilstone is replaced by a wood block wrapped with linen or fine canvas, and the wood block is arranged on a millstone of a millstone machine for polishing until the surface of the plate is smooth and bright.

9. Sealing caulking

(1) And silicone weather-resistant sealant is embedded in gaps among flashing stone plates, gaps between the vertical face stone plates and the parapet walls and gaps between the vertical face stone plates and the adjacent plane pavement.

(2) The sealing surface is cleaned by toluene, and special attention should be paid to not allow the solution to be diffused out of the joint. The gauze used for cleaning is required to be replaced in time after being dirty, so that the cleaning effect is ensured. Finally, wiping off the trace of the evaporated solvent by using dry and clean gauze, and keeping the sealing surface dry.

(3) In order to prevent the sealing material from polluting the decorative surface and prevent the interface between the sealing glue seam and the surface layer from being flat and straight when in use, a protective paper tape is stuck before glue injection, and the paper tape is noted to be flat and straight.

(4) Injecting glue: should be uniform, dense and full, and the gluing method should be paid attention to avoid waste.

(5) And (3) trimming a glue seam: after glue injection, a small shovel is used for exerting pressure on the glue seam along the glue injection direction, redundant glue is scraped off, and the glue seam is scraped into an inner arc shape, so that the glue seam is smooth.

(6) Removing the paper adhesive tape: after the adhesive joint is finished, the protective adhesive tape is timely removed, the surface of the plate is not polluted by the torn adhesive tape, and the adhesive mark stuck to the construction surface is timely cleaned.
