Description

windows for piping

technical field

The invention relates to a pass-through for pipelines. In particular, the present invention relates to a window for a pipeline configured to penetrate a seam roof.

Background technique

Buildings often provide windows or openings for pipes which penetrate the roof of the respective building. The windows interrupt the continuity of the roof and are generally constructed to maintain the integrity of the roof against rain and snow. As a result, different structures have been developed to seal windows, outlets or openings in roofs.

For example, document WO 2004/003311 A1 discloses a base plate for piping of roofs with profiled profiled coverings, in particular roofs assembled from profiled covering elements, comprising a collar and a flange, the collar enclosing The pipe, the flange is in contact with the roof covering. The flange is intended to be fitted and secured under the covering element such that only the collar protrudes from an aperture formed in the covering element, the flange is formed to conform to the contour of the covering element, the upper surface of the collar has a groove for sealing material A number of parallel annular grooves surround the collar.

Seamed roofs require other systems and methods to seal openings provided in sheet metal roofs, which essentially consist of flat panels joined together by raised seams. For example, document US4497151 describes such a standing seam metal roof assembly formed from elongated metal plates. The pitch angles of such seamed roofs are typically in the range of 13° and 50° to provide sufficient water flow.

For example, document US5027576 discloses an arrangement for sealing an opening in a roof by installing a baffle in the roof to provide a through going ducting channel, the roof having at least one raised seam intersecting the opening, the baffle The size of the plate is such that it extends beyond the perimeter of the opening in substantially all directions, thereby defining an overlapping region extending substantially around the entire perimeter of the opening, the arrangement comprising cover members for covering and sealing the baffle, raised A region where seams and openings converge; support and reinforcement members for positioning on the surface of the top panel opposite the baffle and at least partially in the overlap region; and fastening means for extending through the covering in the overlap region members, baffles, roofs and support and reinforcement members and fasten them together. The proposed solution for sealing the opening in the roof is complex and requires significant manpower to securely attach the arrangement to the roof. For different roofs with different pitch angles a specific structure is necessary.

In view of the foregoing, it would be beneficial to provide a window for piping configured to penetrate a roof such as a seamed roof having a pitch angle of between 13° and 50°. In this context, a seamed roof is a roof with a generally flat or smooth weatherproof covering. Besides metal sheets, such roofing materials are, for example, stone, fiber-reinforced cement or felt. Seamed sheet metal roofs are usually made by joining strips of sheet metal using standing folded seams.

Furthermore, there is a need for a compact window. Such windows should be suitable for uncomplicated, cost-effective industrial production.

detailed description

The window is especially designed for use in roofs or roof covering elements shaped to provide a profile similar to a seamed roof. Due to the simple and compact structure, the installation of the window can be carried out quickly. The same window can be used on different roofs, each with a different pitch angle.

In Fig. 1, a first perspective view of a window 1 for tubing according to at least some embodiments of the present invention is shown. The window 1 comprises a collar 2 providing an annular opening 3 for a conduit (not shown). The collar 2 is formed so that the window 1 is available for any slope of the roof in the range between 13° and 50°. In other words, the window 1 can be used for different seam roofs with slopes in the range between 13° and 50°, for example 35°. This is also supported by the annular form of the opening 3 . The plane defined by the upper and lower edges of the opening 3 is inclined relative to the plane formed by the flange 4 at an angle α between 25° and 35°, preferably 30°. The collar 2 also includes a rim 9 comprising four connectors 10 configured to be attached to a roof covering sheet seal (not shown). The body of the window 1 is usually made of plastic material, such as polypropylene.

The opening 3 of the collar 2 is configured to provide an opening for tubing having a diameter of 160 mm or less.

Furthermore, the window comprises a substantially flat flange 4 configured to be attached to a portion of a roof with a slope in the range between 13° and 50°. The window can be placed on top of the roof cladding, preferably the fixing of the window 1 to the seamed roof is carried out by screw fasteners. According to some embodiments, the flange 4 may additionally be covered on the bottom surface with a sealing material such as silicone. The flange 4 comprises a protrusion 6 on the side facing the ridge. The upper edge (not shown) of the arcuate part tightly fixed to the pipe is set between the protrusion 6 and the collar 2 .

The window 1 is made in one piece by injection molding.

Due to the combination of the form of the collar 2, the annular form of the opening 3 and the angle of inclination of the plane of the opening 3, the window 1 can be used for seamed roofs with any slope in the range between 13° and 50°. The windows are designed to be installed after the weatherproofing material is installed.

In Fig. 2, a second perspective view of a window 1 for tubing according to at least some embodiments of the present invention is shown. Between the protrusion 6 and the collar 2, a groove 7 is arranged to receive an arched portion (not shown) tightly attached to the pipe, thereby preventing water from penetrating to the upper edge 9 of the collar opening. The distance from the bottom of the groove 7 to the upper edge 9 of the collar opening defines the damming height of the window. When the window is tightened on the roof to ensure the function of the seal on the bottom surface of the flange, the bottom of the groove 7 should not reach the upper surface of the weatherproofing.

In FIG. 3 , a window for a conduit is shown in accordance with at least some embodiments of the present invention. The window 1 comprises a collar 2 which provides an opening for tubing (not shown). The window 1 also includes a generally flat flange 4 configured to be attached to a portion of a roof. The window 1 preferably comprises a thermoplastic elastomer seal 5 bonded to its bottom surface along the flanged edge. The integral seal 5 is produced simultaneously with the main body of the window in a two-component injection molding process. The width of the integral seal 5 at the ridge-facing edge of the flange 4 is generally greater than the width of the integral seal 5 at the sides and edges facing the eaves. The seal arrangement is configured to increase the durability of the seal 5 and provide a tight seal especially where the water loading is greatest.

In an alternative, a separate seal and window fabricated from a single plastic part could be used.

Furthermore, the plane A-A formed by the opening 3 is set at an angle α in the range between 25° and 35° relative to the plane B-B formed by the flange 4 . According to a certain embodiment, the inclination angle α is 30°. In addition, the form of the opening is preferably elliptical, the collar 2 is formed so that, without changing the window, for different pitch angles of the roof (for example, for any pitch angle in the range between 13° and 50° ), the pipeline can be installed basically in the vertical direction.

In FIG. 4 , a schematic view of the opening 3 of the collar 2 of the window 1 for the pipeline is shown in the plane A-A. The figure is illustrative and does not limit the scale of the openings. The opening 3 is substantially elliptical, with its smaller width denoted x, the edges closer to each other being in the direction of the roof slope. The distance x preferably allows pipes with a diameter of 160 mm or less to pass through the opening 3 . The maximum width of the opening, denoted y, is the distance between the upper and lower edges of the opening. The opening 3 is shaped to allow the passage of the pipes and to set it vertically regardless of the pitch angle of the roof and flange part 4 in the range between 13° and 50°.
