The present application claims priority to German Patent Application No. 10 2020 200 318.1, filed Jan. 13, 2020, which is incorporated herein by reference in its entirety.
The present invention relates to a method of assembling a ceiling formwork, a scaffold used in such a method, and the use of a mounting means in such a scaffold.
For the concreting of building ceilings, their shape is initially specified by a ceiling formwork representing the surface of the building part. Such ceiling formwork is usually formed by formwork elements in the form of formwork panels. When assembling such a ceiling formwork, a first formwork panel is first arranged at a so-called connection point or anchor point, at which further formwork panels are arranged and successively the entire ceiling formwork is provided. The term “attachment point” is usually taken to mean an existing interior wall, an existing column or the like. The first formwork panel can be attached or arranged at such an attachment point, for example, by means of a wall bracket or the like.
It has now become apparent that there is a further need to improve the assembling of such ceiling formwork.
Against this background, it is an object of the present invention to provide an improved method for assembling a ceiling formwork. These and other objects, which will still be mentioned when reading the following description or which may be recognized by the person skilled in the art, are solved by the subject matter of the independent claims. The dependent claims further develop the central idea of the present invention in a particularly advantageous manner.
A method of assembling a ceiling formwork according to the invention comprises at least the following steps: Providing a scaffold arranged adjacent to an area where a ceiling formwork is to be provided; arranging a mounting means for a first ceiling panel member on the scaffold; arranging the first ceiling panel member on the mounting means; arranging at least one support beam member below the first ceiling panel member to hold the first ceiling panel member in a horizontal position.
In other words, the present invention now proposes that a ceiling formwork no longer starts from a wall or column inside the building as an anchor point, as has been the case in the past, but from a scaffold located outside the building. The assembling of the ceiling formwork is therefore no longer carried out according to the inside to the outside, but according to the outside to the inside. The present invention is based on the realization that the assembling of a ceiling formwork at the edge of a building is comparatively costly and complicated. One of the reasons for this is that, in the case of assembling from the inside to the outside, compensating elements/finishing panels and projections over the outside of the building must be provided at the edge area of the building and thus in the area of the fall-off edges, wherein work in this area may generally only be carried out using personal protective equipment. The proposed approach from the outside to the inside means that these compensation areas are now shifted to the inside of the building, where they are easier to control and work can basically be carried out without personal protective equipment. In addition, the proposed approach has the advantage that, by starting at the scaffold, it is possible to carry out length compensation inside the building without any major planning effort. In contrast, planning according to the previous method from the inside to the outside is relatively time-consuming, since planning has to be done from a fixed starting point and the outside areas only allow a small amount of length compensation. Furthermore, the present invention is based on the realization that in many cases a scaffold is already available, which can be used for assembling a ceiling formwork. As a result, the assembling of a ceiling formwork can be considerably simplified and, moreover, made safer by the present invention.
The term scaffold is to be understood broadly in the present context and includes all scaffold structures, which in particular also include facade scaffolds, climbing scaffolds, working scaffolds, platforms, etc. In addition, the term mounting means is also to be understood broadly and includes all means configured to attach or arrange a ceiling panel member to a scaffold, wherein an arrangement of a ceiling panel member can be made directly/indirectly on the mounting means or indirectly/indirectly via a further element. Such a further element can thereby be, for example, a longitudinal strip, a head element or the like. In particular, means can be used as mounting means which allow the ceiling panel element to be suspended from above and/or to be pivotably fastened.
Preferably, the support beam member is disposed at an edge portion of the ceiling panel member, wherein the support beam member is configured to be used as a support beam member for a ceiling panel member adjacent to the ceiling panel member.
Advantageously, at least one further support beam member is arranged below the ceiling panel member. In this context, it is preferred that the further support beam member is arranged adjacent to the scaffold and/or adjacent to a building edge. In practice, it is preferred that respective support beam member are arranged in the corner areas or transition areas to an adjacent ceiling panel member in order to be able to provide the most even load distribution possible. However, depending on the application and requirements, more or fewer support beam member can also be used.
Preferably, the mounting means is configured to be arranged on a vertical post of the scaffold, wherein the mounting means for attachment to the vertical post of the scaffold preferably comprises at least one scaffold clamp element or one scaffold clamp element. The arrangement of the mounting means or means on a vertical post of the scaffold thereby has the advantage that the mounting means can be comparatively easily fixed to an intended height at which the ceiling formwork is to be arranged. Alternatively or additionally, the mounting means can further comprise at least one leveling device with which fine adjustment of the height can be performed. This can be done, for example, by means of leveling screws or the like.
Furthermore, it is preferred that the mounting means comprises at least one arcuate projection element with which the ceiling panel member is engaged and can subsequently be pivoted into a horizontal position. Such an arcuate projection element may, for example, take the form of an arcuate toothed element oriented upwardly. In such an embodiment, the ceiling panel member includes a corresponding reception into which the projection element can be inserted. From such a suspended position, the ceiling panel member can subsequently be pivoted to a horizontal position. An advantage of such an arrangement is in particular that such a hanging and pivoting can be carried out by only one person. Alternatively or additionally, instead of the reception, the ceiling panel member can also comprise a corresponding projection element, for example a straight or an arcuate toothed element, which can be inserted into a reception of a mounting means provided on the scaffold, preferably from above. Such a mounting means can be provided, for example, by a rosette element arranged on the vertical post of the scaffold and having corresponding receptacles into which corresponding projection elements, for example in the form of locking head elements, of the ceiling panel members can be inserted. This allows the ceiling panel member to be suspended from above, for example, so that the ceiling panel member can also be mounted more easily on the scaffold side.
In a preferred embodiment, a plurality of mounting means are arranged on the scaffold to which at least one longitudinal beam member is attached, and wherein the longitudinal beam member is configured to attach, preferably pivotally attach, a plurality of ceiling panel members. The longitudinal beam member may, for example, comprise a series of arcuate projections or arcuate teeth to which a plurality of ceiling panel members may be arranged along the entire longitudinal side. The ceiling panel members can thus be arranged or fastened directly to the fastening means or indirectly via another member, such as a longitudinal beam member or a. Alternatively or additionally, a plurality of projections, for example in the form of locking head elements or the like, can also be provided on the ceiling panel member, which can be brought into engagement with correspondingly designed fastening means, for example rosette elements, on the scaffold.
Furthermore, the present invention further relates to a scaffold comprising: at least one mounting means configured to preferably pivotally mount at least one ceiling panel member to the scaffold, directly or indirectly via an intermediate member, such as a longitudinal beam, wherein the mounting means is preferably arranged on a vertical post of the scaffold, and wherein the mounting means preferably comprises at least one scaffold clamp member and/or a scaffold clamp member. In this context, it is preferred that the mounting means comprises at least one arcuate projection element or tooth with which the ceiling panel member is engageable and pivotable to a horizontal position. Furthermore, it is preferred in this context that a plurality of mounting means are provided on the scaffold to which at least one longitudinal beam member is attachable to which, preferably pivotally, a plurality of ceiling panel members are attachable. As already explained above, the ceiling panels can thus be arranged directly on a mounting means or indirectly on the scaffold, for example by means of a longitudinal beam member. With respect to the further possible embodiments, the above explanations apply.
Finally, the present invention relates to a use of a mounting means for arranging at least one ceiling panel member on a scaffold described above. With respect to the possible design of the mounting means and/or the scaffold, the above explanations also apply here.
Further features, advantages and possible applications of the present invention will be apparent from the following description, the embodiment example and the figures. Therein show:
The mounting means 30 shown further comprises at least one arcuate projection element. Such an arcuate projection element may, for example, be formed as an arcuate toothed element oriented upwardly. In such an embodiment, the ceiling panel member 40 includes one or more corresponding receptacles into which the projection member may be inserted. From this suspended position shown in
As shown in
As can be clearly seen in the figures, the assembling of the ceiling formwork is no longer carried out from the inside to the outside, but from the outside to the inside. It is therefore no longer necessary to provide compensating elements/finishing panels and cantilevers beyond the outside of the building on the outside, i.e. in the area of the fall edge. By proceeding from the outside to the inside as shown, the compensation areas are now moved to the inside of the building, where they can be more easily controlled and work can basically be carried out without personal protective equipment. As a result, the present invention makes the assembling of a ceiling formwork considerably simpler and, moreover, safer.
However, the present invention is not limited in this respect to the foregoing preferred embodiments as long as it is encompassed by the subject matter of the following claims. In particular, the present invention is not limited to a direct/immediate arrangement of the first ceiling panel member on the mounting means.
