Description

[0001] The invention relates to a kit for a parapet structure on a building, wherein the kit comprises at least the following: at least one parapet element made of metal, wherein the parapet element comprises vertically oriented, spaced-apart bars, an upper and a lower metal profile, wherein these two metal profiles are spaced apart from each other in the vertical direction, such that the upper ends of the bars open into the upper metal profile and the lower ends of the bars open into the lower metal profile, and at least one extension which engages at least the lower metal profile, wherein the two metal profiles each have a front facing the building and an opposite back facing away from the building.

[0002] Parapets are known from the prior art that are placed on top of a largely completed ceiling or floor structure. Typically, such a structure is produced by pouring a self-hardening building material such as a concrete mix.

[0003] The installation of a permanent parapet on the aforementioned ceiling or floor structure requires precise work by the fitters, involves a considerable amount of work, and is associated with the use of numerous loose parts.

[0004] One objective of the invention is to create a way to overcome the disadvantages of the prior art.

[0005] This problem is solved with a kit of the type mentioned above, in which, according to the invention, the vertical extension projects from the lower metal profile, wherein the at least one vertical extension has at least one projection, preferably in the form of a mandrel, wherein the projection projects at least 3 cm, preferably at least 10 cm, from the metal profile in the normal direction.

[0006] This kit can be efficiently manufactured in the factory and contains a small number of different components that can be pre-assembled into a single-piece parapet element without any loose parts. It can be attached to the building, for example, to a formwork structure, even before the pouring of a permanent floor or ceiling, especially one made of concrete. By pouring the concrete into the floor or ceiling, a permanent and dimensionally stable connection to the building is achieved.

[0007] The term "projects in the normal direction" means that there is a minimum perpendicular distance of 3 cm. It is not required that the projection necessarily projects at a right angle. Thus, the projection can also project obliquely or asymmetrically. The projection can connect directly or indirectly to the lower metal profile. The metal profile can, for example, have a wall thickness between 4 mm and 12 mm. The upper and lower metal profiles do not have to be identical. Any geometric shape is conceivable, including, for example, the possibility that the lower metal profile has a rectangular cross-section and the upper metal profile is a tubular profile with a round cross-section. The parapet element can also be referred to as a railing element, and the parapet as a railing. Spatial terms such as "top," "bottom," "front," "back," etc., refer to the state when mounted on the building.

[0008] The metal used can be, for example, steel, in particular S355 or S235 to S255 steel, which may be hot-dip galvanized and possibly additionally coated with plastic / painted.

[0009] In particular, it may be provided that at least the front side of the lower metal profile lies within a vertically oriented plane, hereinafter referred to as the reference plane, wherein the upper and lower metal profiles are of the same design and wherein their front sides lie within the reference plane.

[0010] Furthermore, it may be provided that the elongated appendage has at least two vertically spaced projections in the form of two spines.

[0011] In particular, it may be provided that at least two vertical extensions are formed on the parapet element, which are identical in design and are shifted parallel to each other in the horizontal direction, with the distance between the vertical extensions being between 40 cm and 160 cm.

[0012] Furthermore, it can be provided that the two standing extensions have the same distance to the center of the longitudinal extent of the lower metal profile.

[0013] In particular, it may be provided that at least the front of the lower metal profile lies within a vertically oriented plane, hereinafter referred to as the reference plane, wherein the bars each have a front facing the building (in the fixed state) which extends to the reference plane.

[0014] Furthermore, it can be provided that the bars each have a back side facing away from the building, with these back sides lying within a further plane.

[0015] In particular, it may be provided that the bars are of identical construction and evenly spaced from each other.

[0016] Furthermore, it may be provided that the longitudinal extent of the metal profiles is between 0.5 m and 2 m.

[0017] In particular, it may be provided that the vertical distance between the lower and upper metal profiles is between 1.16m and 2m.

[0018] Furthermore, it may be provided that the lower metal profile is arranged either below the at least one projection or at a distance of at least 65cm above the at least one projection.

[0019] If two or more projections are arranged one above the other, this distance is measured from the nearest projection. A distance of at least 65 cm from the bottom – depending on the floor's finished floor level (FBOK) – prevents the projection from creating an unintended climbing aid. In Austria, for example, the limit is 60 cm above the FBOK, and the distance can be chosen to ensure this value is not undercut.

[0020] In particular, it may be provided that the bars have a rectangular cross-section, wherein the width of the bars, which is oriented parallel to the longitudinal extent of the metal profiles, is less than their depth, wherein the depth is between 30 and 60 mm, in particular between 40 mm or 50 mm, and the width is between 3 mm and 8 mm.

[0021] Furthermore, it may be provided that the rods have a round cross-section with a diameter between 15mm and 30mm.

[0022] In particular, it may be provided that the outer bars are flush with the ends of the longitudinal extension of the metal profiles.

[0023] Furthermore, the kit may include at least one parapet element in which one extension engages the lower metal profile and extends downwards from the lower metal profile, preferably with a length of at least 60 cm, and more preferably at least 80 cm. If the lower metal profile is designed as a horizontal section of an L-shaped profile, with one vertical leg extending downwards from the front of the metal profile, the engagement of the extension with the lower metal profile is to be understood as allowing a mechanical connection via the vertical leg as well.

[0024] Furthermore, it can be provided that the lower metal profile is designed as a horizontal section of an L-shaped profile, with a vertical leg extending downwards from the front of the metal profile.

[0025] In particular, it may be provided that at least one projection is arranged within the lowest 30 cm of the longitudinal extent of the vertical extension and that at least one projection is spaced at least 65 cm away from the lower metal profile.

[0026] Furthermore, it may be provided that the kit includes a cement-bonded panel, namely a cement-bonded fine particleboard or a cement-bonded flat-pressed panel, which is designed to be screwed to the standing extension, wherein the length of the panel corresponds to the length of the lower metal profile and wherein the panel is designed to engage flush with the lower metal profile and to extend vertically downwards from there.

[0027] Cement-bonded particleboard or cement-bonded flat-pressed particleboard can be manufactured according to EN 13986:2004, for example. Such a board is free of voids and has a density of approximately 1250 to 1400 kg / m³. It is particularly weather-resistant, extremely stable, and can be manufactured with very high dimensional accuracy. Typical thicknesses are 4 cm or 5 cm. However, the dimensions can vary depending on the requirements.

[0028] The cement-bonded fine particleboard or cement-bonded flat-pressed board is typically pre-assembled at the factory and delivered to the construction site in a state connected to the parapet element.

[0029] In particular, it may be provided that the overall height, which is composed of the height of the plate and the distance between the lower metal profile and the upper metal profile, is at least 1.1 m.

[0030] Furthermore, it may be provided that the height of the plate is greater than the height of the rods and in particular is at least twice the value.

[0031] In particular, it may be provided that at least the front of the lower metal profile lies within a vertically oriented plane, hereinafter referred to as the reference plane, with the vertical extension extending within the reference plane.

[0032] Furthermore, it may be provided that the plate has a recess for the partial reception of the peduncle, wherein the peduncle preferably extends beyond this recess by at least 2 mm.

[0033] In particular, it may be provided that the pedicle has a thickness between 15 mm and 50 mm.

[0034] Furthermore, it can be provided that the lower metal profile is designed as a horizontal section of an L-shaped profile, with a vertical leg extending downwards from the front of the metal profile.

[0035] In particular, it may be provided that the L-shaped profile is made of metal and has a material thickness between 5mm and 10mm.

[0036] Furthermore, it can be provided that the lower metal profile has a depth between 40mm and 60mm, and wherein the vertical leg has a vertical length between 40mm and 160mm and extends along the entire length of the lower metal profile.

[0037] In particular, it may be provided that the plate is designed to engage the L-shaped leg in a form-fitting manner, wherein the upper edge of the plate facing the L-shaped profile is chamfered, so that a tolerance is given to compensate for weld seams or unevenness in the inner edge of the L-shaped profile.

[0038] The inner edge refers to the area where the two legs of the L-profile meet. Alternatively, instead of a weld, a bending radius might be present if the profile is bent; this bending radius can be compensated for by chamfering the edge. This means the edge of the panel is chamfered in such a way that the L-profile does not collide with a weld or any potentially small bending radius and can be fully slid onto the building surface.

[0039] Furthermore, it can be provided that the extension is connected to the lower metal profile via the vertical leg of the L-shaped profile by having at least one, preferably two, bores in the L-shaped profile, wherein the extension extends at least to the at least one bore and has an internal thread, so that the L-shaped profile can be screwed tightly to the extension by inserting a screw into the bore and screwing it in with the internal thread.

[0040] The L-shaped profile is screwed to the extension, which has an internal thread for this purpose, and the screw preferably ends before reaching the subsequent cement-bonded slab. The extension can protrude approximately 2 mm beyond the slab on the building side, so that any unevenness in the slab can be compensated for and the extension can lie flush and flat against the building.

[0041] In particular, it may be provided that mounting wings project from the vertical extension, forming a flush front face of the vertical extension facing the building and having a thickness of less than 50% of the thickness of the remaining vertical extension. The vertical extension has one mounting wing at the level of the vertical leg of the L-profile, such that the mounting wing is covered by the vertical leg when installed. A further mounting wing is provided at a distance of at least 30 cm below this point. Each mounting wing has holes by means of which the mounting wing can be securely screwed to the panel. The mounting wing may have a thickness of less than 50% of the thickness of the vertical extension. The width of the wing to the left and right of the vertical extension may be more than 50% of the width of the vertical extension.

[0042] Furthermore, it may be provided that the kit includes at least one parapet element in which a metallic cover plate is fully attached to the front of the lower metal profile, covering the entire longitudinal extent of the metal profile and extending from the lower metal profile along the bars to a height of at least 60 cm parallel to the bars.

[0043] In particular, the cover plate may be permanently connected to the bars, especially by welding. The upright extension need not be flush with the lower metal profile, but may also be offset upwards to reduce the lever arm when a person leans against the railing. In this case, there would be an indirect connection to the lower metal profile via the cover plate and the bars typically located behind it.

[0044] Furthermore, it can be provided that the vertical extension extends vertically upwards from the lower metal profile, wherein the vertical extension is designed as a mechanically reinforced section, in particular as a retaining plate with increased wall thickness compared to the cover plate.

[0045] In particular, it may be provided that the height of the cover plate is between 20% and 80%, in particular between 30% and 50% of the total height of the parapet element, which total height is in particular at least 1.1 m.

[0046] Furthermore, it may be provided that the kit also includes a privacy screen parapet element, which is designed as a full-surface cement-bonded panel, namely as a cement-bonded fine chipboard or a cement-bonded flat-pressed panel.

[0047] In particular, it may be provided that the height of the privacy screen parapet element corresponds to the height of the remaining parapet elements.

[0048] Furthermore, it can be provided that the privacy screen parapet element has a metallic cover at its upper end to prevent water from entering the upper end, wherein a metallic fastening element with at least one projection is formed in a lower area of ​​the privacy screen parapet element, the projection preferably being of the same type as the projections of the remaining parapet elements.

[0049] In particular, it may be provided that the longitudinal extent of each parapet element is limited by two opposite end faces into which the metal profiles open, with screw openings being formed on these end faces in such a way that adjacent parapet elements can be firmly connected to each other at their end faces by screwing two opposite screw openings together.

[0050] The screw opening can be provided with an internal thread, or it can be made without a thread.

[0051] Furthermore, it may be provided that the screw openings are positioned in such a way that the upper metal profiles of adjacent parapet elements can be connected in a flush alignment with each other.

[0052] In particular, the screw holes can be designed as vertically oriented elongated holes. The screw holes of adjacent parapet elements are screwed together before the concrete is poured – during the construction of the formwork for the floor / ceiling edge.

[0053] Furthermore, it may be provided that at least one parapet element made of metal is attached to the building by incorporating at least one projection into a floor and / or ceiling structure of the building produced by hardening a previously liquefied building material, in particular concrete, and thus firmly connecting it.

[0054] Furthermore, the invention relates to a method for constructing a parapet structure on a building using a kit according to the invention, comprising the following steps: a) Providing a number of parapet elements prepared for assembly, where said preparation means that the parapet elements are each one-piece (i.e.a) The parapet elements are formed (free of loose parts) and have at least one projection prepared for connection to the building; b) The number of parapet elements according to step a) is attached to the floor and / or ceiling formwork, the formwork being prepared to be at least partially filled with a liquefied building material, in particular concrete; c) Adjacent parapet elements are joined at their ends; d) The liquefied building material is applied to the formwork, the material being applied in such a way that the projections of the parapet elements are enclosed by the liquefied building material; e) The building material is allowed to cure for a certain period, so that after the curing period the parapet elements are firmly connected to the hardened building material via the projections.

[0055] The number of parapet elements is at least two, but can be chosen to be any higher, so that the total length of the parapet elements corresponds to the required length of the parapet of a building.

[0056] The parapet elements can be attached before being fixed with the building material according to step b), for example, by bracing them against wooden structures. The mutual connection according to step c) further increases the positional stability of the parapet elements. The parapet elements can then be optimally aligned together before they are permanently and firmly anchored by applying and allowing the building material to harden.

[0057] In addition to the parapet elements, the privacy screen parapet elements can also be attached in the same way.

[0058] All features and processes mentioned in connection with the kit or device can of course also be provided for in the course of the process.

For ease of reading, the two types were referenced with different letters "a" and "b", and this referencing continues for the components of the parapet elements. Thus, the reference 3a2u designates the lower metal profile of the parapet element of the first type "a", 3a2o the upper metal profile of this parapet element, 3b2u the lower metal profile of the parapet element of type "b", etc.
