(2) piled bricks is built by laying bricks or stones:

Cleaned out at piled bricks position, roof, use 1:3 cement mortar screeding, build piled bricks by laying bricks or stones, piled bricks is perpendicular to roof, and pre-buried piled bricks is connected with iron wire with purlin, and build height by laying bricks or stones and be as the criterion with roof pitch after installing roof tile, slope angle controls at 15 °;

(3) purlin is installed:

A. purlin flitch in roof makes;

B. purlin is connected with eaves and hammers into eaves by 5 cun of steel nail horizontal directions;

C. other position adopts two purlin form, and purlin is connected with the piled bricks 10# iron wire colligation imbedded in advance;

D. colligation is overlapped at piled bricks position between purlin and purlin;

E., after the whole installation of purlin, by the purlin of middle piled bricks to eaves purlin hanging wire, wedge wedge shape wood bottom purlin, its purlin angle is adjusted, make the parallel tiling of purlin, fastening iron wire;

(4) roof tile is installed:

A. roof tile adopt 1.8m grow up waveform asbestos shingle or composite tile and other be suitable for watt;

B. tile is connected with purlin: install from bottom to top; Add cover twice waterproof apron with 5 cun of steel nails to hammer into purlin and be connected with purlin by tile, the vertical lap length of tile is 250mm ~ 300mm, along purlin direction shingle lap 1 ripple; Tile chooses eaves 200mm;

C. ridge tiles is installed: electricity consumption is drilled on waveform tile and ridge tiles and is fixed after punching;

(5) waterproof gasket cement is sealed:

Bian Shou angle, slope; Seal waterproof gasket cement between ridge tiles and pantile, corner, roof is played glue and is fixed.

Adopt the present invention of technique scheme, compared with prior art, its outstanding feature is:

Waterproof and thermal insulation structure of the present invention is equivalent to add a cover the brick joisted roof of one deck at deck, and the integrated cost of its material and construction is low, and ageing resistace is strong, and by the asbestos shingle quality of existing market supply, its aging time limit is at least more than 20 years; Owing to have employed built on stilts herringbone structure form, can ensure that deck is cool in summer and warm in winter, and good looking appearance; Be highly resistant to the impact of the unfavorable factors such as natural rain, snow, wind, frost, solar radiation, temperature Change, ensure that building interior has a good environment for use.

Detailed description of the invention

The present invention is further elaborated for the embodiment provided below in conjunction with accompanying drawing, but embodiment does not form any restriction to the present invention.

See Fig. 1 to Fig. 4, a kind of construction method of flat roof water-proof insulation construction, carry out in the steps below:

(1) surveying setting-out:

1. first on roof 1, carry out surveying setting-out, measure corner, roof whether in same level, whether uprightly measure roof.

2. accurately find out the position on roof corresponding to load bearing wall 2, eject 240mm × 240mm square piled bricks 3 position line with the line of ink marker, prolong load bearing wall 2 direction and arrange, the distance controlling between piled bricks 3 center and piled bricks 3 center is being not more than 1.5m.For the one-storey house of 8 meters of spans, per pass load bearing wall 2 is arranged 5 place's piled bricks 3.

(2) piled bricks is built by laying bricks or stones:

Roof piled bricks 3 position is cleaned out, uses 1:3 cement mortar screeding, build 240mm × 240mm piled bricks 3 by laying bricks or stones, build by laying bricks or stones perpendicular to roof 1, and pre-buried 10# iron wire, build height by laying bricks or stones and be as the criterion to install the rear roof pitch of roof tile 4, slope angle should control at about 15 °.For the one-storey house of 8 meters of spans, the height of middle piled bricks 3 is for exceeding eaves absolute altitude 1.2 meters.

(3) purlin is installed:

1. roof purlin 5 adopts 40mm × 80mm × 4m flitch to make, and selects flawless, without distortion, without insect pest, moisture content is the high-quality flitch of 8% ~ 12%.

2. purlin 5 and eaves connect employing 5 cun of steel nail 9 horizontal directions and hammer into eaves (nail is parallel with roof), and its object is for increasing roof wind loading rating.

3. other position adopts two purlin form, to make watt to have between purlin 5 more multi-link like this, to make watt to bear larger pulling force between purlin 5.Purlin 5 is connected with piled bricks 3 and adopts 10# iron wire 7 colligation to connect.

4. the type of attachment between purlin 5 and purlin 5 is for carry out overlap joint colligation at piled bricks 3 position.

5. purlin 5 is all after installation, by the purlin 5 of middle piled bricks 3 to eaves purlin hanging wire, wedges wedge shape wood 8, adjust, make the parallel tiling of purlin 5, fastening iron wire to its purlin 5 angle bottom purlin 5.Its object is to increase watt and the lifting surface area of purlin, reduces the pressure of purlin corner angle, the application life to increase watt.

(4) roof tile is installed:

1. roof tile 4 adopt the large waveform asbestos shingle of 1.8m × 0.7m or composite tile and other be suitable for watt.

2. tile is connected with purlin: carry out from bottom to top installing (roof tile can go up people), and method that cover twice waterproof apron hammers into purlin connects to adopt 5 cun of steel nails 8 to add, and vertical lap length is 250mm ~ 300mm, and prolonging purlin direction spacing is 0.7m.Every sheet watt overlap joint 1 ripple.Watt choose eaves 200mm.

3. ridge tiles is installed: electricity consumption is drilled on pantile and ridge tiles 6 and is fixed after punching, prevents mounted tile and ridge tiles 6 breakage.

(5) waterproof gasket cement is sealed:

Bian Shou angle, slope; Seal waterproof gasket cement between ridge tiles 6 and pantile, corner, roof is played glue and is fixed.Bian Shou angle, slope requires neat, fair line, and tile fixedly requires firm, attractive in appearance.

The foregoing is only the better feasible embodiment of the present invention, not thereby limit to interest field of the present invention, the equivalent structure change that all utilizations manual of the present invention and accompanying drawing content are done, be all contained within interest field of the present invention.
