Abstract

It is formed on wooden rafters (1) anchored to the substrate by anchoring brackets (14). The rafters (1) are placed perpendicular to the wall of the house on the suburbs (5) built on the perimeter structure of the building and on wooden posts - braces (2) with a gradient from the cladding to the interlayer trough (3) formed along the inlets (8) of the rainwater from trough plates (9) nailed perpendicular to the rafters (1). On the rafters (1) there is also a wooden decking (7) on the entire roof surface. A final layer (10) of sheet metal or other roof covering is placed on the structure thus formed. At the level of the new truss, a wooden side hatch (11) is created around the perimeter of the building, protected from the outside by a weatherproof covering (12). Ventilation grilles (13) are fitted into the side flap (11). The braces (2) are made of prisms and are laid on wooden plank slippers (4) placed on the roof in the longitudinal direction of the roof at specified spacing. The entire roof surface is covered with thermal insulation (6).

Description

Roof with an interstitial collecting gutter

Technical field

The solution applies to roofs of buildings with flat sloping roof surfaces.

BACKGROUND OF THE INVENTION

On family houses as well as residential or industrial buildings are used flat roofs, which waterproofing and eventually. thermal insulation covering, mainly cardboard, follows the building roof cladding. The advantages of such roofs are simple technology and low-cost investment. Their disadvantage is insufficient roof slope. On such a roof there are places from which rainwater does not run out but stands to evaporate. As a result of sunlight, alternating day and night temperatures and the effects of frost, such roofs become bulged and cracked over time. A more preferred solution is low gabled or hipped roofs, which tend to guarantee rainwater run-off to gutter corners on the perimeter of the building. Such a roof is usually covered with a covering with a longer life. It is a sheet metal, tiles, etc. Gable or hip roofs used in buildings where rainwater outflows are designed and constructed in the central part of the roof and pass inside the building would render these outflows inoperable. They would have to be replaced by drains made again on the outside of the building, which is not an optimal solution.

The essence of the technical solution

The above-mentioned disadvantages are eliminated by the present technical solution, which is based on the fact that the roof is designed as inverted wooden beams - rafters anchored into the foundation and placed perpendicular to the house wall on the perpendiculars built on the circumferential attic of the building. a cladding to the inter-roof drainage trough, which is formed on the roof surface along the rainwater inlets. It is made up of gutter boards nailed perpendicular to the stored rafters. Roof rafters made of wood panels are nailed to the rafters over the entire roof area. A final layer of sheet metal or other roofing material is deposited on the wooden structure thus formed. At the level of the new truss, a wooden side flap is created along the perimeter of the building with gaps between its boards, protected from the outside by a weather-resistant covering. Ventilation grilles are fitted in the side flap in certain sections. The struts are made of wooden prisms and are laid on wooden plank slippers, laid on the roof underlay in the longitudinal direction of the roof at specified spacing. The roof is equipped with thermal insulation, which covers the entire surface of the roof base.

The advantage of the technical solution stands out especially in reconstructions of flat roofs of older apartment buildings with insulation of cardboard. From these roofs, rainwater pipes are routed inside the house and their outlets are usually in the central part of the roof of the building.

BRIEF DESCRIPTION OF THE DRAWINGS

The roof according to the invention is shown in the attached fig. 1. Its central trough intersects, in the left part the first three fields show the construction of the roof, in the next three fields the thermal insulation is placed and the lower part represents the roof flap. The right half shows the finished roof with the final layer. Ventilation shafts, lift engine rooms and roof hatches are not shown in FIG. 1.

Ob. 2 shows Detail A of FIG. 1

EXAMPLES

An exemplary embodiment is a roof with a wooden truss anchored to the substrate formed on wooden beams - 10x10 cm cross-sections 1 perpendicular to the wall of the house on wooden props - struts 2. with a slope of about 3 ° from the cladding to the interstitial gutter The rafters 1 are anchored to the roof underlay by means of anchoring angles 14 with which they are connected by nails. The spacing of the anchoring angles 14 is determined as necessary. The anchoring bracket 14 is chemically attached to the roof substrate. mortar and threaded rods, screws, respectively. steel anchors. The struts 2 are made of wooden prisms. The rafters 1 are associated with so-called. a carpentry joint to the barb and attached to them with nails. The struts 2 are laid and secured on wooden plank slippers 4, placed on the roof underlay in the longitudinal direction of the roof with spacing of approximately 2 m. It secures the nail joint. The distance of two adjacent struts 2 on one slipper 4 is about 1 m. The slope of the roof structure to the inter-roof collecting gutter 3 is also formed by means of sidings 5 mounted on the circumferential attic and fastened to it by anchoring elements. Thermal insulation 6 of polystyrene or mineral wool of at least 10 cm thickness is laid on the roof substrate. A wooden roof flap 7 of 2.5 cm thick slabs with a maximum gap of 7 cm between the slabs is nailed to the rafters 7 over the entire roof area. The inter-roof gutter 3 is made along the inlets 8 of rainwater with nailed gutter boards 9 of a thickness of 2.5 cm. The boards are directed perpendicularly to the laid rafters 1. On this wooden construction a final layer 10 of coils of galvanized or plastic coated sheet is deposited. . Ventilation ducts of the ventilation system and roof outlets are raised above the level of the new roof covering and trimmed around the perimeter. Possible elevator shafts are also edged along the perimeter at the level of the new roof. Along the perimeter of the building, at the level of the truss, a wooden side flap 11 of 2.5 cm thick boards is formed on which the roofing 12 is formed of anodized sheet metal. Ventilation grilles 13 with dimensions 15 x 15 cm with spacing of approx. 2 m are mounted on the side of the roof.

Another exemplary embodiment is a roof with two parallel guided interstitial gutters 3. Here, according to the invention, the roof is inclined from the edge of the building to the closer inter-roof gutter 3. A low gabled roof is formed between the gutters.

Another variant is a roof on which rainwater inlets 8 are connected and an inter-roof collecting trough 3 is attached thereto closer to one edge of the building.
