FLAT ROOF STRUCTURES SUPPORT

Description

[0001] The space available on a flat roof is often used to install technical building equipment or roof terraces above the flat roof. Such objects, which are permanently mounted above the flat roof, are permanently supported on the flat roof by means of a flat roof support. For inspection purposes, the flat roof support protrudes at least 50 cm above the top edge of the flat roof structure. Such flat roof support is custom-made and consists of a hollow cylindrical tube with plates welded to both ends. After the plates are welded on, ventilation openings are inserted into the tube to allow for subsequent galvanization of the flat roof support on its inside as well. Nevertheless, applying the zinc layer is difficult. It is not possible to control whether the zinc reaches every point inside the hollow cylindrical tube of the roof support.As a result, it is uncertain whether the roof structure support is adequately protected against corrosion.

[0002] DE 31 48 046 C2 discloses an anchoring post for fastening to a building roof. It consists of a tube welded to an anchoring plate and open at the top. It has a welded-in ring with an internal thread, into which a cap with a tubular external thread is screwed.

[0003] A two-part roof structure support is known from JP 4 653 578 B2.

[0004] The invention is based on the object of providing a durable flat roof structure support.

[0005] This object is achieved by a flat roof structure support having the features of claim 1.

[0006] A further object of the invention is to provide a method for producing a flat roof superstructure support for permanently supporting an object to be permanently mounted above a flat roof on the flat roof, with which a durable flat roof superstructure support can be produced.

[0007] This object is achieved by a method having the features of claim 11.

[0008] The flat roof structure support according to the invention comprises a lower tubular element and an upper tubular element. The lower tubular element is formed separately from the upper tubular element. The base of the flat roof structure support is arranged on the lower tubular element. The head of the flat roof structure support is arranged on the upper tubular element. The lower tubular element has an upper tubular element end. The upper tubular element end faces away from the base arranged on the lower tubular element. The upper tubular element has a lower tubular element end. The lower tubular element end faces away from the head arranged on the upper tubular element. The lower tubular element end is open at its upper tubular element end. The upper tubular element end is open at its lower tubular element end. The flat roof structure support comprises a connecting device for connecting the lower tubular element to the upper tubular element.

[0009] Because the flat roof superstructure support comprises at least the lower tubular element and the upper tubular element as components, and because the two tubular elements are each open at the ends facing each other when assembled, corrosion protection, in particular full-surface corrosion protection, can be easily applied to the inside of the tubular elements. The insides are thus easily accessible, and the corrosion protection can be applied without obstruction. A subsequent visual inspection to determine whether the inside is completely protected against corrosion is readily possible. Due to its two-part design, the flat roof superstructure support according to the invention can be reliably manufactured with full-surface corrosion protection. This is not possible with the prior art.

[0010] Due to the flat roof support structure's construction, which consists of a lower tubular element and an upper tubular element, the flat roof support structure can also be easily thermally insulated on the inside. To do this, an inner insulation element is inserted into the interior of the upper or lower tubular element before the lower tubular element is connected to the upper tubular element using the connecting device. Only then is the upper tubular element or the lower tubular element connected to the other tubular element using the connecting device. This is also not possible with the current technology. Depending on the installation situation, a decision can be made on site whether or not an inner insulation element should be installed.

[0011] Furthermore, the flat roof superstructure support according to the invention allows for adjustment of the support height due to the separate design of the lower and upper tubular elements. The design of the flat roof superstructure support with a lower tubular element and an upper tubular element allows for relative movement of the lower tubular element relative to the upper tubular element to adjust the support height. The support height can be adjusted flexibly and easily on-site at the construction site.

[0012] The inventive design of the flat roof superstructure support, with its lower tubular element and the upper tubular element formed separately from the lower tubular element, enables the flat roof superstructure support to be used for a wide variety of applications. Unlike in the prior art, it is no longer necessary to manufacture each flat roof superstructure support specifically for a specific application; instead, the flat roof superstructure support according to the invention can be adapted to the respective operating conditions with regard to support height and thermal insulation. The flat roof superstructure support according to the invention provides a standard support. The introduction of such a standard saves time and money in the planning and production of the flat roof superstructure support. Statics and thermal insulation no longer have to be calculated individually for each specific construction project, but can be calculated once for the flat roof superstructure support according to the invention.The standardized design of the flat roof support allows for cost-effective, large-scale production. The flat roof support according to the invention can be produced in advance and delivered quickly and cost-effectively when needed. The tedious and time-consuming search for a metalworker who can custom-make the flat roof support for a specific construction project is eliminated.

[0013] A professional and permanently tight seal for the flat roof superstructure support penetrating the roof waterproofing was previously impossible. Due to its separation into a lower and an upper tubular element, the flat roof superstructure support according to the invention enables simple and reliable sealing of a transition between the flat roof superstructure support and the flat roof. Due to the separation into an upper and lower tubular element, when installing the flat roof superstructure support according to the invention, the lower tubular element can first be fixed to the flat roof and then a sealing element, in particular a tubular sealing element, preferably a shrink tube, can be slipped over the lower tubular element or the upper tubular element such that the lower tubular element or the upper tubular element completely penetrates the sealing element.The sealing element can then later be pulled to the transition between the lower pipe element and the flat roof or the upper pipe element and the flat roof, where it can fulfill its sealing function. In particular, the sealing element can be shrunk there by heating. The part of the sealing element protruding from the roof waterproofing can be expediently shrunk onto the upper pipe element or the lower pipe element by heating. This enables very simple and efficient sealing of the transition between the flat roof structure support and the flat roof. This allows the flat roof structure support to be integrated into the roof waterproofing in a professional and standard-compliant manner. The use of a tubular sealing element is not possible in the current state of the art due to the limitation of each end of the tubular support by a plate projecting beyond the outer surface of the pipe.

[0014] Advantageously, the lower pipe element can be connected to the upper pipe element using the connecting device in such a way that the lower and upper pipe elements define a common cavity. This cavity can be used to accommodate an insulation element for thermal insulation of the flat roof structure support. With previous one-piece supports, the support cavity could only be filled with foam, which inevitably resulted in larger cavities. Due to air convection, these cavities significantly reduce the thermal insulation value of the structure. The cavity described here, defined by the lower and upper pipe elements, can be easily filled with an insulation element designed as an insulation core. This ensures flawless insulation of the cavity.

[0015] The cavity defined by the lower and upper pipe elements can be easily protected from corrosion when the two pipe elements are separated. In particular, corrosion protection can be easily applied when the two pipe elements are separated.

[0016] The upper tubular element and the lower tubular element can be connected to one another using the connecting device without the need for a material connection. This enables a simple and quick connection of the lower tubular element to the upper tubular element. In particular, the upper tubular element and the lower tubular element can be connected to one another using the connecting device without the need for tools.

[0017] The connecting device expediently comprises a screw connection. Preferably, a first part of the screw connection is formed on the lower tubular element, and a second part of the screw connection is formed on the upper tubular element. Preferably, the lower tubular element and the upper tubular element can be connected to one another by means of the screw connection without the need for tools.

[0018] The flat roof superstructure support has a support height measured in its longitudinal direction. The flat roof superstructure support is specifically designed so that the support height can be adjusted by a relative movement of the lower tubular element and the upper tubular element to each other. In particular, the support height can be adjusted by gradually turning the screw connection in the loosening direction or gradually turning the screw connection in the closing direction. The adjustability of the support height allows the flat roof superstructure support to be quickly and easily adapted to different application conditions with regard to the required support height. Tolerances of ± 2 cm are permissible in the shell construction. The quick height adjustment via the screw connection makes it easy to compensate for shell construction tolerances. This eliminates the need for recalculating the statics. This saves time and money.In particular, there's no need to place an order for a custom-made product. This saves the time-consuming and costly search for a metalworker. The flat roof support can be stored and kept in stock for various purposes. This allows for rapid deployment.

[0019] The flat roof structure support advantageously has a locking element for blocking relative movement between the upper tubular element and the lower tubular element. This allows the connection between the upper tubular element and the lower tubular element to be secured by means of the connecting device. In particular, after setting the desired support height of the flat roof structure support, relative movement between the lower tubular element and the upper tubular element can be prevented, thus fixing the flat roof structure support at the desired support height. Advantageously, rotation of the upper tubular element relative to the lower tubular element can be prevented by means of the locking element. In particular, the screw connection between the lower tubular element and the upper tubular element can be secured against rotation by means of the locking element.

[0020] According to the invention, the flat roof structure support has an inner insulating element for thermal insulation. The inner insulating element is arranged in both the upper tubular element and the lower tubular element. The insulating element preferably extends in the longitudinal direction of the flat roof structure support from the base to the head of the flat roof structure support. The inner insulating element enables good thermal insulation of the flat roof structure support. Due to the at least two-part design of the flat roof structure support, the inner insulating element can be easily inserted into an open end of the lower tubular element or the upper tubular element. During the subsequent connection of the lower tubular element and the upper tubular element to one another, the inner insulating element can be inserted into the other tubular element.According to the invention, the inner insulation element protrudes from the lower pipe element in such a way that, when connecting the lower pipe element to the upper pipe element, the upper pipe element can be slipped over the inner insulation element. In particular, the inner insulation element is a soft insulation core. This allows for easy height adjustment of the roof structure support. The insulation element, designed as a soft insulation core, can be compressed to the required height and completely fill the cavity defined by the upper and lower pipe elements.

[0021] In particular, both the upper and lower pipe elements are fully galvanized. In particular, the upper and lower pipe elements are fully galvanized on their inner surfaces. This ensures good corrosion protection. Because the flat roof structure support is designed in at least two parts, with a lower pipe element and an upper pipe element, and because the lower and upper pipe element ends are each open, galvanizing can be carried out and checked easily. The zinc can be introduced into the two pipe elements through the upper and lower pipe ends, respectively. A visual inspection can then be used to easily determine whether the entire inner surface of the respective pipe element is completely protected against corrosion by zinc. It can also be checked whether the outer surface of the respective pipe element is completely protected against corrosion by zinc.With the previous one-piece supports, galvanizing was carried out via a small galvanizing opening and a small vent opening. This made it virtually impossible to check whether the cavity was completely galvanized and could not be performed on site.

[0022] In an advantageous development of the invention, the flat roof structure support comprises a sealing element. In particular, the sealing element is tubular. Preferably, the sealing element is a shrink tube. The sealing element serves to seal the transition between the flat roof structure support and a flat roof, in particular against liquid. Because the flat roof structure support comprises a lower tubular element and a separately formed upper tubular element, the sealing element, in particular the tubular sealing element, can first be slipped over the lower tubular element or the upper tubular element during assembly of the flat roof structure support. In this case, the lower tubular element or the upper tubular element can be inserted through the sealing element.After assembling the lower pipe element and the upper pipe element and / or after mounting the lower pipe element on the flat roof, the sealing element can be easily moved to the transition between the lower pipe element or the upper pipe element and the flat roof, where it can provide a seal. In particular, the sealing element can be heated at the transition point between the lower pipe element or the upper pipe element and the flat roof, and can form a seal against both the flat roof and the lower pipe element or the upper pipe element. This enables efficient and simple sealing of the transition between the flat roof and the flat roof structure support. It can also be provided that the sealing element seals a connection point between the lower pipe element and the upper pipe element, in particular in addition to sealing the transition between the flat roof structure support and the flat roof.

[0023] The flat roof support advantageously comprises an outer insulation sleeve for thermal insulation. In particular, the outer insulation sleeve encloses at least the upper pipe element. The outer insulation sleeve expediently completely encloses the flat roof support in the circumferential direction along the longitudinal direction of the flat roof support. In particular, the outer insulation sleeve extends from the flat roof to the head of the flat roof support. This allows for good thermal insulation of the flat roof support in a simple manner. It can also be provided that the outer insulation sleeve encloses both the upper and lower pipe elements.

[0024] According to the inventive method for producing a flat roof superstructure support for the permanent support of an object to be permanently mounted above a flat roof, when installing the flat roof superstructure support on the flat roof, the lower tubular element is first fastened to the flat roof by its base. In a subsequent process step, the upper tubular element is connected with its lower tubular element end to the upper tubular element end of the lower tubular element. This type of assembly enables the production of the upper tubular element and the lower tubular element in such a way that efficient and reliable corrosion protection of the two tubular elements is possible. The corrosion protection can be applied in the factory before the flat roof superstructure support is installed. In this case, it is not necessary to create ventilation openings in the flat roof superstructure support, as is the case with the prior art.The open design of the pipe elements at their ends allows for sufficient air exchange during the production of corrosion protection, for example by galvanizing.

[0025] The assembly method according to the invention also allows for the simple insertion of an insulating element into the interior of the lower or upper pipe element. This allows the flat roof structure support to be thermally insulated in a simple manner.

[0026] The inventive manufacturing method for flat roof superstructure supports makes it possible to design the flat roof superstructure support with an adjustable height. This allows for adaptation to different operating conditions with regard to the support height of the flat roof superstructure support. This enables a standardized manufacturing process with a unique design regarding statics and thermal insulation. The inventive method eliminates the need for time-consuming and costly custom production of the flat roof superstructure support.

[0027] The method according to the invention also enables simple sealing of the transition between the flat roof superstructure support and the flat roof. Before the upper pipe element is connected to the lower pipe element, a sealing element, in particular a tubular sealing element, preferably a shrink tube, can be slipped over the lower pipe element or the upper pipe element and later pulled to the transition location. The sealing element can act as a seal there. In particular, the sealing element can be shrunk there by heating. This enables an efficient and simple method of sealing the transition between the flat roof and the flat roof superstructure support.

[0028] According to the method according to the invention, before the lower pipe element is connected to the upper pipe element, an inner insulation element is inserted into the lower pipe element for thermally insulating the flat roof structure support. Expediently, after the lower pipe element has been fastened with its base to the flat roof, the inner insulation element is inserted into the lower pipe element for thermally insulating the flat roof structure support. According to the invention, the inner insulation element is inserted into the lower pipe element in such a way that the inner insulation element protrudes from the lower pipe element and then, when the lower pipe element is connected to the upper pipe element, the upper pipe element is slipped over the inner insulation element. Expediently, the inner insulation element is then received in the upper pipe element.In particular, the inner insulation element, once housed inside the flat roof support, extends from the base of the flat roof support in the longitudinal direction of the flat roof support to the head of the flat roof support. This enables simple and efficient thermal insulation of the flat roof support. In particular, the inner insulation element is a soft insulation core. This allows for easy height adjustment of the roof support. The insulation element, designed as a soft insulation core, can be compressed to the required height and completely fill the cavity defined by the upper and lower pipe elements.

[0029] The method is expediently expanded in that, before the lower pipe element is connected to the upper pipe element, a sealing element, in particular a shrink tube, is slipped over the lower pipe element or the upper pipe element to seal the transition between the flat roof structure support and the flat roof. This allows the transition between the flat roof and the flat roof structure support to be easily sealed using the sealing element. In particular, it is provided that, after the lower pipe element has been secured with its base to the flat roof, the sealing element is slipped over the lower pipe element or the upper pipe element to seal the transition between the flat roof structure support and the flat roof.

[0030] In particular, the method involves adjusting the support height of the flat roof structure support, measured in the longitudinal direction of the flat roof structure support, by moving the upper tubular element relative to the lower tubular element. The support height is advantageously adjusted by a connecting device, which is particularly designed as a screw connection. Advantageously, a first part of the screw connection is arranged on the lower tubular element, and a second part of the screw connection is arranged on the upper tubular element. In particular, following adjustment of the support height, the upper tubular element is secured against movement relative to the lower tubular element by means of a locking element. This ensures that the support height is permanently and securely adjusted.

[0031] In particular, both the upper and lower pipe elements are fully galvanized before the lower pipe element is connected to the upper pipe element. It is advisable to fully galvanize both the upper and lower pipe elements before installing the flat roof support. In particular, the inner surfaces of the lower and upper pipe elements are fully galvanized. This allows for easy and reliable corrosion protection of the flat roof support, both on the inside and outside.

[0032] An embodiment of the invention is explained below with reference to the drawing. It shows: Fig. 1 a schematic sectional view of a flat roof superstructure support mounted on a flat roof with an object arranged thereon and supported by the flat roof superstructure support.

[0048] The flat roof structure support 1 comprises a connecting device 8. The connecting device 8 serves to connect the lower tubular element 4 to the upper tubular element 5. The connecting device 8 can connect the upper tubular element 5 to the lower tubular element 4 in such a way that the flat roof structure support 1 formed thereby can absorb the weight of the object 40 arranged on the flat roof structure support 1. The connecting device 8 is designed in particular such that the flat roof structure support 1 can absorb at least a weight of 500 kg, preferably at least a weight of 1000 kg. The lower tubular element 4 can be connected to the upper tubular element 5 by means of the connecting device 8 in such a way that the lower tubular element 4 and the upper tubular element 5 delimit a common cavity 9.In the assembled state of the flat roof superstructure support 1, the common cavity 9 extends in the longitudinal direction 50 from the base 2 to the head 3. The upper tubular element 5 and the lower tubular element 4 can be connected to one another by means of the connecting device 8 without a material connection. The lower tubular element 4 and the upper tubular element 5 can be connected to one another on site at the construction site by means of the connecting device 8.

[0049] In the exemplary embodiment, the connecting device 8 comprises a screw connection. It can also be provided that the connecting device 8 is formed exclusively by a screw connection. In the exemplary embodiment, a first part 10 of the screw connection is formed on the lower pipe element 4. A second part 20 of the screw connection is formed on the upper pipe element 5. One of the two pipe elements 4, 5 comprises an external thread and the other of the two pipe elements 4, 5 an internal thread.

[0050] However, it can also be provided that the connecting device 8 does not comprise a screw connection, but rather a different type of connection. For example, it can be provided that the connecting device is designed as a plug-in connection. In this case, a groove or a fold can be provided on at least one of the two tubular elements 4, 5, against which the other tubular element rests when the flat roof structure support 1 is assembled.

The locking element 11 prevents a relative movement between the upper tubular element 5 and the lower tubular element 4. In the exemplary embodiment, the locking element 11 secures the two tubular elements 4, 5 against relative movement by means of frictional force. To do this, the locking element 11 presses on the inner tubular element 4, 5, in the exemplary embodiment on the lower tubular element 4. In the exemplary embodiment, the locking element 11 is screwed through a side wall of the upper tubular element 5, in particular through a side wall of the base body 22 of the upper tubular element 5, and presses on the outside of the side wall of the lower tubular element 4, in particular on the outside of the side wall of the base body 17. In the exemplary embodiment, the locking element 11 is a screw.The locking element 11 acts in a transverse direction, in particular perpendicular to the longitudinal direction 50.

[0052] The locking element 11 is screwed through the side wall of the base body 22 of the upper tubular element 5 in a direction perpendicular to the longitudinal direction 50. In the exemplary embodiment, the locking element 11 is a component of the connecting device 8.

[0053] The flat roof structure support 1 has a support height h measured in the longitudinal direction 50.
