Description

STAND AND SYSTEM TO SUPPORT THE SITE FOR WATERPROOFING

The invention relates to a base for supporting an object to a waterproof structure, the base comprising a fastening response for fixing the object and a support member for supporting the base to the waterproof structure, the support member being a flange adapted to be installed between two waterproofing layers of the waterproofed structure. The invention also relates to a system for supporting an object on a waterproof structure. Water-insulated structures, such as roofs, are used, for example, for the installation of solar power plants. Other structures can also be installed on the roofs, such as antennas and base stations. Typically, on sloping roofs, solar power plants are installed via a pedestal. The base comes into direct contact with the waterproofing or a platform, such as a concrete slab, is placed under the base. In addition, depending on the application, a thin release strip is installed between the base and the waterproofing or the concrete slab and the waterproofing, which at the same time improves the friction between the waterproofing and the base or the concrete slab. Finally, concrete slabs or similar weights are placed on the base to achieve a sufficient counterweight to keep the solar power station in place on the roof. The 2 bad aspects of the installation are the almost pointy additional load coming to the roof and + the structural parts attached to the roof surface that prevent the flow of water z on the roof. The extra weight can cause damage to the 3 waterproofing and the structures under the waterproofing. = 30 In the worst case, the weight N of the solar power plant and installation can block the ventilation grooves of the roof under the waterproofing, open the 5 seams of the creams and cause depressions and ponds on the roof surface.

The object of the invention is to provide new types of stands and a system for supporting an object on a waterproof structure. The characteristic features of the stand and the system according to the invention appear from the appended protection requirements.

The invention will now be described in detail with reference to the accompanying drawings, which illustrate some embodiments of the invention. Figure 1 shows a first embodiment of a stand according to the invention mounted on a waterproofing, Figure 2a shows a top view of a second embodiment of a stand according to the invention, Figure 2b shows a partial enlargement of a second application of a stand according to the invention seen from the side. Figure 1 shows an arrangement according to the invention in which one stand 10 according to the invention is mounted. The stand 10 comprises a fastening stop 11 for fastening the object and a support member 12 for supporting the stand 10 on the waterproof structure. First, the support member 12 is a flange 13 which is large enough. In this case, the weight of the solar power plant is distributed over a large area. This avoids the formation of point loads. The weight of a solar power plant is usually about 20 - 25 kg / m ?. The solar power plant 25 comprises several solar collectors, which are supported by several stands. Preferably the flange has a diameter of + 300 to 600 mm, preferably 350 to 450 mm. In the application of Figure 1 = the diameter of the round flange is 400 mm. a

N 5 30 Curved shapes are preferably used, thus avoiding sharp N angles. Thus, when the stand is loaded, the force S on the flange does not cause a sharp angle depression in the waterproofing. In the embodiment shown, the flange is round, but may be oval, oval, or a rectangle rounded at the corners. The round stand is easy to install. On the other hand, different dimensions can be used to optimize the load-bearing capacity of sloping roofs, more generally with waterproof structures.

In addition to a sufficient size, a sufficient material strength is provided in the flange. In this case, the load-bearing capacity of the stand is sufficient without bending the stand. Thus, the attachment to the roof is guaranteed to remain without damage to the waterproofing. The strength of the material depends in part on the material used, but the aim is to keep the flange as even as possible without harmful protrusions. Attaching the stand is also new and surprising. As shown in Figure 1, the base 10 is installed as part of the waterproofing, here between the bitumen creams 14 and 15. The base and system are also suitable for PVC roofs. Adhesion is improved by openings 16 in the flange, here holes. Through the holes, the bitumen extends through the base. If necessary, additional bitumen is extruded during installation and under and over the flange, thus ensuring that the components adhere to each other. Larger holes allow mechanical attachment to the base if necessary. The open area formed by the holes is about 10 to 20% of the area of the stand. This ensures adequate infection.

S S 25 The adapter piece of the stand can be moved so that the body of the solar power plant coming on top of it can be fitted to it and the heat movement in the frame can move freely. In the application of Fig. 1, there is a platform 17 in the middle of the flange 13, to which a support 18 is fitted with a bolt 3 connection. At the same time, when installed, the oval hole is preferably oriented according to the maximum thermal expansion. In this case, seasonal temperature changes do not stress the adhesion of the flange to the waterproofing. Here, too, the two flanges of the support have oval holes.

In Figure 1, a first bitumen cream is first installed on the roof substructure, which is preferably a multi-layer roofing cream 14 to be welded on both sides.

The welding bitumen penetrates through the openings 16 through the flange 13.

If necessary, additional bitumen is used.

Thereafter, a second double-sided weldable multilayer underlayment 15 is preferably installed, which is welded to the flange 13 and the first underlay 14. Here, the surface layer consists of a surface cream 19, which at the same time forms the visible surface of the roof.

The choice of surface cream is mainly influenced by the appearance, but also by other properties.

After installation, the waterproofing must be kept clean, only the platform and support will remain visible, but will be covered when the solar power plant is installed.

The stand is sure to stay in place without additional weights.

With a suitable manufacturing technique, instead of a product welded from parts, the flange and the platform can, for example, be deep-drawn or pressed or otherwise formed from a sheet into one piece.

The structure and form of the support may also vary.

Preferably, a support according to each application is attached to the universal flange.

Figure 2a shows a modification of the stand 10 according to the invention. o Also in this flange 13 there are openings 16, but the platform has been replaced with O 25 threaded rod 20. The object to be supported can thus be attached to the threaded rod 2.

In Fig. 2b, a threaded rod 20 is provided with two nuts 21 and two washers 22 with rubber or plastic bags z 23.

The nuts can be used, firstly, to adjust the height of the attachment point to the desired level and, secondly, to press the object to be supported = 30 between the nuts.

The puzzles bring some flexibility to the attachment.

N In addition, angle brackets, 5 which are attached to a threaded rod, can be used for support.
