Installation of metal

2. Installation of metal
 
 
2.1. Measurement sheets
 
Over the length of the sheet usually takes a long slope. If the slope of the roof, there are projections (see. Fig. 4), it is necessary to consider a step (400 mm - type 1 and 350 mm — type 2 and 3) that in places of transition into sheets of different length coincided pattern tiles.

If the slide has a stepped shape or the length of a slope b m, the installation of the roof can be used sheets of different length. When covering the slope with two or more sheets, consider nahlest- 130 mm. In exceptional cases, when ordering sheets should report on additional joint it.
The recommended length of a shaped roof is listed in Table 1.

Table 1: Metal .
 
Sheets of 1/1025 in some long have additional transverse bending, which facilitates installation and prevents the spread of the edge of the sheet, which should be considered when ordering sheets type 1/1025 of different lengths on the same slope. If the roof has a complex shape, or you decide to use a tile-type 1/1025 best carefully measure the entire roof, and for the calculation of the length of roofing sheets to refer to specialists.
 
 
2.2. Calculation sheets.
 
Calculate the number of sheets in the following way; the length of the cornice is divided by the useful width of the profile sheet and rounded up to a full unit (multiplied by the number of ramp). Useful width of the last sheet = total width of the ramp. Width (nominal) metal cm. In Table 1. The measurements of hip roof, cut a sheet of metal or trapezoidal form, can not be used in the mirror — the opposite slope of the transverse corrugation pattern. Qualified personnel for the calculation of roofing Weckman help calculate the flow-sheet for your roof.
 
2.3. Waterproofing flooring and ventilation slats.
 
Under the sheets need to use the lower deck waterproofing, preventing the ingress of condensation on the roof structure. Flooring rastilayutsya overlap in the direction of the ridge, since the area of ​​the eaves. Secure the flooring to the rafters, for example, rivets. Overlap flooring — an average of 150 mm. Do not pull tight flooring between the rafters, leave about 20 ... 30 mm free deflection. On both sides of the ridge (ridge tent) pull in an excess of more than 150 mm floor (see. Division 2.4). Flooring stretch zone eaves so that condensation does not trickled down to the wall structure and to freely air jet could pass to the upper deck (see. Figure 5).
In the area of ​​gable overhang: Deck stretch over a distance of 200 mm from the outermost point of the wall structure (see. Figure 5).

2.4.1 Ventilation lathing.
 
Above deck waterproofing in places rafters nailed ventilation slats so that the stream of air from the eaves to freely pass between the flooring and roofing sheets.
The air is removed from the eaves through the ventilation ridge (ridge tent) or short skate buildings (up to 10 m.) Through the end of the shaped ridge. When roofing abutment at the junction of the roof with the wall, ventilation is carried out by the scheme, for example, as shown in Figure 9.
 
2.4.2. Lower deck ventilation.
 
Zone eaves should ensure the smooth direction of the air stream from the eaves in podnastilovoe ventilation space, which is then removed through the wind attic windows. The roof structure where insulation is directed along the ramp to skate gidronastil not stretched to the ridge is left uncovered at the ridge (approx. 100 mm) and the ingress of water into the structure prevents the ventilated ridge seal " TOP - ROLL " (see. Figure 7) or ventilation horse (see. Fig. 8). To prevent the infiltration of moisture on the crate under the horse nailed a strip of waterproofing material.

For a hip and gable roof in the same manner set ventilation horse. The lower ventilation gap under the floor for the entire length of the structure must be at least 100 mm.
 
 
2.5.   Crate
 
When selecting the thickness of the batten should take into account the height of the profile sheet and the corresponding length of the fastener (when fastening with the wave profile). Minimum cross-section boards — 32h100 mm (Fig. 5). Overlooking the cornice board should be thicker than the other. For molded tiles of type 2 and 3 — 10 mm thicker in tile type 1 - 15 mm thick. Interval installation batten for the fitting of the roof corresponds to the multiplicity of shingles. Boards attached a rafters hot dip galvanized nails 2,8h75 mm (2 pcs./Chiasm).
Warning! Not to beat a horse, leave enough ventilation gap (see Fig.10).

When installing two or more sheets, use the bar under the joint.
 
2.6 Stacking sheets
 
During installation should be carefully walk on the metal, since the sheet can not withstand heavy loads! When walking on the profile sheet, to advance in the field crates: along the — in bending waves across the — for pleated profile. When installing the sheets, the capillary groove of each sheet must be served, followed by leaf. Stacking sheets start from left to right or vice versa. When installing metal roofing from the right side, the edge of the next sheet slips under the latest wave of the previous page (capillary groove on the right edge of the wave), which facilitates installation and prevents slipping of the last sheet, due to its cross-crimping.
Sheets placed the eaves, with the projection of the cornice 45 mm. Installation should begin by strengthening the first sheet with one screw in the middle at the ridge, in the trough of the wave. Then lay the second sheet and seal overlap with one screw at the top of the first wave of a transverse fold. Check that the transverse folds well-joined and bottom edges make a smooth line. Two sheets fasten together with screws in the joint it 4,8h2,8 mm under each transverse fold. Secure thus 3 — 4 sheets together and align with the help of tracer cord bottom edge of the eaves. Only after this sheet is attached to the crate. Installing these sheets continue attaching the sheet first a the previous list and only then fastened to the furring.
 
Mounting plates for horizontal lap (see. Figure 12).

2.7. Fixture sheets.
 
The recommended length screws 4.8 x 50; 4.8 x 65 or 4.8 x 80 mm for fastening on the top of the wave. screws 4.8 x 28 mm are used for fastening the roofing sheet on the bottom of the wave, from the eaves to the overlap and for mounting brackets (see. Figure 14). For fastening roofing sheets using the screws provided with seals (EPDM rubber). Expedient fixing screws than nails, as the reliability of fastening screws twice.
To avoid dents in the sheet, the screws should not be tightened. For screwing the screws using an electric drill with stepless speed regulation and reverse motion.

V - shaped bracket razzhelobki installed as follows (see. Fig. 15).
Start the installation with laying gidronastila razzhelobki along the direction razzhelobki and attach to the rafters. Then waterproofing flooring installed across the roof (see. Section 2.3).
Install ventilation slats on the slope (eg. 32h50 mm), leaving approximately 50 mm to the support unit. Wooden flooring razzhelobki start from the reference node at a distance of approximately 50 mm thickness is used planks (32h100mm) is the same as that of the sheathing. Next, a crate adjacent rays at intervals corresponding multiplicity of tiles.
Strengthen several screws from the eaves at the junction razzhelobki to the sheathing. Overlap strips for razzhelobki - not less than 200 mm, and the overlap seams are sealed with mastic.
Fasten roofing sheets to the crate and lay the seal between the roofing sheet and strip razzhelobki.
The distance between the edges of the roofing sheets have razzhelobki about 200 mm.

2.9 pass-through output
 
Recommended setting through terminals as close as possible to the ridge/upper ledge. Around the fire hatch, ventilation and lance pipes are supporting bars and the necessary additional boards (solid wood construction, sm.ris.11). All joints should be carefully sealed. Overlap the basics of fire and ventilation hatch lance roofing sheets similar-lap sheets. The set of conclusions through (VILPE-fans, air outlets, air and sewage) includes seal, base with seal, seal of roof penetrations of meteoustoychivoy EPDM rubber (detailed assembly instruction attached to the kit).
Do not allow large snow loads on the output, if necessary, to remove the snow.
If the distance from the ridge to the withdrawal of more than a meter, it is recommended installing ice and snow breakers over the output.
 
2.10 ice and snow breakers
 
For safe operation of the roof we recommend installing ice and snow breakers in places of possible snowmelt. Ice and snow breakers mounted in the wall zone of the bearing structure. Prior to installation of roofing sheets, set parallel to the slope of the board additional support, such as 50x100 mm, for fixing bases ice and snow breakers. Attach the base plate mounting bases ice and snow breakers (4 pcs./Set) at a distance of 750 mm from each other on the bottom of the wave 8mm screws or bolts and washers. Between the roofing sheet and laid the basis for fixing the sealing tape Zx30. Install the oval/or round tubes (2 pcs./Set) for fixing the fundamentals, and secure the edges of pipes consoles 8h35 mm (see. Fig. 17).
