Description

Device for constructing an outer corner of a ceiling formwork, ceiling formwork, horizontal support, support head, height adjustment element and bracing adapter and method for constructing an outer corner of a ceiling formwork

The present application claims the priority of German Patent Application No. 10 2021 126 176.7, the content of which is incorporated herein by reference in its entirety.

The invention relates to a device for producing an outside corner of a ceiling formwork according to the preamble of claim 1 .

The invention also relates to a ceiling formwork, having a plurality of ceiling panels, according to the preamble of claim 26.

The invention also relates to a horizontal support, a support head, a height adjustment element and a bracing adapter according to claim 27 for a device for producing an outer corner of a ceiling formwork.

The invention also relates to a method for constructing an outside corner of a ceiling formwork according to the preamble of claim 28.

Ceiling formwork is known from the general state of the art in a variety of designs.

Slab formwork is usually made up of slab panels that are placed on slab supports and thus form a surface for concreting a slab. Known ceiling formwork is mostly constructed from above, that is, the person who erects the ceiling formwork stands on a level in which the concreting process is to take place and lays out the ceiling panels there.

Also known are solutions with formwork tables that are brought prefabricated to the concreting location in order to form the ceiling formwork there.

For ergonomic and safety reasons, it is preferable to erect slab formwork from below or from the floor. This reduces the risk of falling. When assembling the ceiling formwork, the ceiling panels are hung on one side from below on a support head of a ceiling support and then swung up into the intended horizontal position, also referred to below as the concreting position. Since the ceiling panels have to be swiveled into an overhead position, additional aids are generally used for this purpose, which are intended to enable or facilitate the swiveling of the ceiling panels. After the concreting process and the hardening of the created ceiling, the ceiling panels are detached from the ceiling in order to be available for subsequent concreting after stripping.

For further prior art, reference is made to DE 10 2020 109 575 A1.

There are special requirements with regard to the structure of a ceiling formwork or the attachment of a ceiling formwork panel for a ceiling formwork in the area of external corners or on cantilevered ceiling edges, especially if a building column runs in these areas.

In these cases, the ceiling formwork is made from ceiling panels in the conventional way as far as possible. At least two ceiling panels are arranged in such a way that they form a first connecting edge and a second connecting edge of the outer corner running orthogonally thereto. To construct an outside corner, especially if a building pillar runs in this area, an individual construction made of floor supports is erected on which horizontal beams are placed. Then timbers are placed on the horizontal beams, which serve as a base for placing a ceiling formwork panel. If a building pillar runs in this area, the ceiling formwork panel has a corresponding opening for the building pillar. Such constructions often also require work from above, so that improvements are desirable for safety reasons alone.

The object of the present invention is to provide a device for constructing an outer corner of a ceiling formwork that solves the disadvantages of the prior art, in particular that can be erected easily, quickly and safely.

According to the invention, this object is achieved by the features of claim 1 .

The present invention is also based on the object of creating a ceiling formwork having a plurality of ceiling panels which are supported and held in position by ceiling supports and which solves the disadvantages of the prior art, in particular can be erected easily, quickly and safely.

This object is achieved by claim 26 according to the invention.

Furthermore, the invention is based on the object of creating a horizontal support, a support head, a height adjustment element and a bracing adapter which support an advantageous construction of an outer corner of a ceiling formwork.

According to the invention, this object is achieved by claim 27 . The present invention is also based on the object of creating a method for constructing an outer corner of a ceiling formwork, in particular in an area in which a building column runs, which solves the disadvantages of the prior art, in particular a simple, quick and safe construction of the outside corner allowed.

According to the invention, this object is achieved by claim 28 .

The device according to the invention for constructing an outer corner of a ceiling formwork has at least a first ceiling panel and a second ceiling panel, which are arranged in such a way that a first connection edge and a second connection edge running orthogonally thereto are formed on the outer corner. The device according to the invention also has at least one ceiling formwork panel and a plurality of horizontal beams which carry the at least one ceiling formwork panel. According to the invention, the device also has a plurality of support heads, with the support heads and the horizontal supports being designed in such a way that a first axial end of the horizontal supports can be detachably fixed to one of the support heads and can be moved from an assembly position to a concreting position in which a longitudinal axis of the horizontal support is plane-parallel to of the slab formwork, can be pivoted upwards, with a first number of support heads being positioned adjacent to the first connection edge and a second number of support heads being positioned adjacent to the second connection edge, and with a first number of horizontal beams being fixed to the first number of support heads and in the concreting position run in a first plane, with the longitudinal axes of the first number of horizontal beams extending in a first direction, starting from the first connecting edge, and with a second number of horizontal beams being fixed to the second number of support heads and running in the concrete position in a second plane, wherein the two planes run plane-parallel to one another and the second plane runs below the first plane, and wherein the longitudinal axes of the second number of horizontal supports extend, starting from the second connection edge, in a second direction that runs orthogonally to the first direction.

The device preferably has at least one vertical support with at least one receiving device for fixing a stop-end formwork of the outside corner, the vertical support being able to be connected to one of the horizontal supports.

The solution according to the invention offers a safe solution for forming from "below" in the corner area of a building with or without a building pillar.

The device according to the invention makes it possible to attach ceiling formwork panels easily, quickly and safely, even in the area of the outer corners of a ceiling formwork. The device according to the invention is particularly advantageous in the case of installation situations at outside corners if a building pillar runs in the area of the outside corner. It should be noted that when the orientation or the position of components, in particular also of axes, are described below, the orientation and the position, unless otherwise stated, refers to the intended use of the respective components. The intended use is to be understood as meaning that the components are used in the way intended for the production of ceiling formwork, i.e. they are in a position and orientation that is referred to as a concreting position in which the ceiling is concreted can. This means that as a rule the position is the final position in which a horizontal beam supporting the ceiling formwork panel generally runs horizontally.

In the assembled position, a longitudinal axis of the horizontal beam runs generally at an angle to the plane in which the ceiling formwork runs.

The ceiling panels used within the scope of the invention can be made of any suitable material, in particular wood, plastic or metal.

The device according to the invention has a plurality of support heads and a plurality of horizontal supports which are designed such that a first axial end of the horizontal support can be detachably fixed to one of the support heads and pivoted up from an assembly position into a concreting position.

As a rule, it is provided that the horizontal beam in the assembly position is hung from below in at least one, preferably in two support heads and then pivoted up, preferably with an assembly aid or a swivel-up aid, for example a formwork aid.

It is advantageous if a bracing chain is hung on the horizontal support and the bracing chain runs at an angle of 45° to 80°, preferably 60°, to the plane in which the ceiling panels or the ceiling formwork panel is arranged.

In the raised concreting position, the horizontal beam can be supported by one or more additional floor props that have suitable support heads. This can be one of the support heads according to the invention or another conventional support head. The other floor props are placed in the area of the second axial end of the horizontal beam.

According to the invention it is provided that a first number of support heads are positioned adjacent to the first connection edge and a second number of support heads are positioned adjacent to the second connection edge.

The first number of support heads is preferably positioned directly on the first connection edge or engages in it. Preferably, the second plurality of support heads are positioned adjacent the second mating edge such that the second plurality of support heads do not engage the second mating edge but are positioned, preferably closely, adjacent the second mating edge.

It is also possible for the second number of support heads to engage directly in the second connection edge and for the first number of support heads to be positioned at a distance from the first connection edge. It is also possible for both the first and the second number of support heads to engage directly in the respective connection edge or be positioned adjacent to the respective connection edge. The feature "positioned adjacent" includes both an adjacent positioning and a direct engagement in the respective connection edge.

The feature of a first number and a second number of support heads is to be understood such that it can also be just one support head, but preferably the first number of support heads and the second number of support heads each comprise a plurality of support heads.

The first number of support heads and the second number of support heads can be identical. However, the first number of support heads preferably differs structurally from the second number of support heads, in particular with regard to the design of the upper side of the support heads.

According to the invention, a first number of horizontal beams are fixed to the first number of support heads and run in the concreting position in a first plane, with the longitudinal axes of the first number of horizontal beams extending in a first direction starting from the first connection edge. The longitudinal axes of the first number of horizontal supports preferably extends in a direction orthogonal to the first connecting edge. According to the invention, it is further provided that a second number of horizontal beams are fixed to the second number of support heads and run in the concreting position in a second plane, with the longitudinal axes of the second number of horizontal beams extending in a second direction, starting from the second connection edge is orthogonal to the first direction. The longitudinal axes of the second number of horizontal supports preferably also run orthogonally to the second connecting edge.

The first number of horizontal beams differs from the second number of horizontal beams in that they are used in different positions within the scope of the device according to the invention, i.e. the first number of horizontal beams runs in the first plane and the second number of horizontal beams in the second level. Structurally, the horizontal supports of the first number and the second number can be identical or a horizontal support that is arranged in the first level can also be used in the second level. The conceptual distinction between the first number of horizontal supports and the second number of horizontal supports relates, within the scope of the invention, to their arrangement in the corresponding plane in the device. Of course, it is also possible in principle that the first number of Structurally differ horizontal beams and the second number of horizontal beams, but this is optional.

According to the invention, it is further provided that the first plane, in which the first horizontal supports run, runs plane-parallel to the second plane, in which the second horizontal supports run. The second level is below the first level, that is to say offset vertically downwards and is therefore formed further away from the ceiling formwork panel. This means that the second level is further away from the ceiling formwork panel in the vertical direction than the first level.

The arrangement of the first horizontal beam and the second horizontal beam in two different levels has the advantage that the horizontal beams of the two levels do not get in each other's way.

According to the invention, it can preferably be provided that the device has at least one vertical support with at least one receiving device for fixing a stop-end formwork of the outside corner. The vertical support can be connected or is connected, preferably detachably connected, to one of the horizontal supports.

The horizontal beams running in the second plane are preferably arranged in such a way that they support the horizontal beams running in the first plane. This can preferably be achieved in that the horizontal beams running in the second plane are correspondingly supported or pushed upwards by support heads or ceiling supports.

The respective support heads are primarily used to support the associated horizontal beams. However, the flow of forces can also run from the horizontal beams running in the first plane via the horizontal beams running in the second plane into a support head or in a ceiling support which supports the horizontal beam running in the second plane.

It is particularly advantageous if the second number of support heads are designed in such a way that they are not only designed to fix the second number of horizontal supports, but also, preferably by means of a corresponding upward extension, i. H. in the vertical direction, are designed in such a way that a correspondingly projecting section of the support heads also directly supports or engages under a horizontal beam that runs in the first plane. The second number of support heads is preferably positioned as closely as possible adjacent to the second connection edge of the second ceiling panel, but preferably does not engage in it.

In principle, however, it is also possible for the second number of support heads to be designed in such a way that they do not engage on a horizontal beam of the first level, but rather on the second connection edge. The second number of support heads can also be designed in such a way that they engage both on a first horizontal beam and on the second connecting edge.

The second number of support heads may also include a group of support heads that engage the second connection edge and a group of support heads that engage horizontal beams of the first level. In principle, it is also possible that the second number of support heads is designed in such a way or a group of the number of second support heads is designed in such a way that they only serve to fix the second number of horizontal supports and press them from below against the first number of horizontal supports .

The vertical support can preferably be connected to a horizontal support in such a way that the vertical support runs orthogonally to the longitudinal axis of the horizontal support. When the horizontal support is in the concreting position, the vertical support preferably runs orthogonally to the plane of the ceiling formwork or the ceiling formwork panel, so that the receiving device of the vertical support can be used in a particularly advantageous manner to fix a stop-end formwork of the outer corner.

The device according to the invention preferably has at least two vertical supports which are each connected to one of the horizontal supports. Provision can also be made for two vertical supports to be connected to a horizontal support. Provision can be made for each horizontal support to be connected to at least one vertical support. However, to define a stop-end formwork, it may be sufficient if some of the horizontal beams are each provided with one or two vertical beams.

The vertical beams can be fastened both to the horizontal beams that run in the first plane and to the horizontal beams that run in the second plane. The vertical beams are preferably connected both to horizontal beams that run in the first plane and to horizontal beams that run in the second plane.

It is advantageous if the support heads are designed as support heads for ceiling props.

In principle, it is also conceivable that the support heads are designed as components of the ceiling formwork panels or are fixed to the ceiling formwork panels in some other way. However, it has turned out to be particularly advantageous for realizing the device according to the invention if the support heads are designed as support heads of ceiling props.

The support heads can each be formed in one piece with one of the ceiling supports. It is particularly advantageous if the support heads are detachably connected, preferably screwed, to the ceiling supports. It is also advantageous if the first number of support heads have a first receiving area on their upper sides which can be brought into engagement with the first connecting edge and have a second receiving area to which at least one of the horizontal supports can be fixed.

It has proven to be advantageous if the first number of support heads have a first receiving area on their upper side, which can be brought into engagement with the first connection edge. This is preferably done in such a way that the support head is designed as a support head of a ceiling support and is immovably fixed to the first connection edge or the first ceiling panel. Although the support head is preferably locked, there is preferably a few millimeters of clearance in order to minimally displace the support head in different directions. Such support heads are known from the prior art and are used, for example, in order to hang another ceiling panel on a ceiling panel and then to place this in a concrete layer and to support the ceiling panels. The support heads of the first number of support heads are preferably designed in such a way that they have a second receiving area on the upper side, on which at least one of the horizontal beams can be fixed, in particular hooked, and then pivoted up from an assembly position into a concreting position.

The first number of support heads may be support heads already in use to support the first ceiling panel.

However, it can also be provided that one or more of the support heads of the first number are not primarily used to support the first ceiling panels, but are placed specifically in order to be able to fix one of the horizontal beams.

It can be advantageous if a first axial end of a horizontal beam of the first number, which runs in the first plane, is fixed to two support heads. It can be provided that the first support head is a support head that is already used in the existing structure, i.e. that it is a support head of a ceiling prop that supports the first ceiling panel, and the second support head with the help of a ceiling prop like that it is ensured that the horizontal beam can be hooked in or that the second support head is positioned appropriately. Such a structure is particularly suitable if the horizontal support, as will be explained in more detail below, is designed as a support frame.

The first horizontal beam, which is fixed in the first plane, is preferably attached in such a way that a longitudinal edge or a longitudinal beam of the horizontal beam in the concreting layer runs adjacent and preferably parallel to the second connection edge. Another support head or a ceiling prop with a support head is preferably positioned after the horizontal beam has been swiveled up into the concreting position in such a way that the support head engages under or into both the horizontal beam and the adjacent second connecting edge of the second ceiling formwork panel.

It is advantageous if a support head, which is brought into engagement with a second axial end region of a horizontal beam running in the first plane after being pivoted up, is positioned in such a way that the support head and thus also the floor prop that carries the support head are opposite the second axial end of the horizontal support is indented, that is positioned displaced towards the first axial end of the horizontal support. It has proven to be advantageous if the support head does not engage at the end of the second axial end of the horizontal support, but is offset somewhat inwards.

It is advantageous if the second number of support heads have a first receiving area on their upper sides which can be brought into engagement with one of the horizontal supports running in the first plane and have a second receiving area on which at least one of the horizontal supports running in the second plane can be fixed .

In principle, it is conceivable to design the first number of support heads and the second number of support heads to be identical. Furthermore, it is also possible to fix the second number of support heads in a suitable manner on the second connecting edge.

However, it has proven to be particularly suitable if the second number of support heads is designed differently from the first number of support heads, in particular in such a way that the top of the second number of support heads has a first receiving area which engages with one of the first Plane running horizontal beam can be brought. The first receiving area is preferably designed in such a way that it can be brought into engagement with a longitudinal edge or a longitudinal beam of the horizontal beam. The second number of support heads are preferably positioned on the horizontal beam running in the first plane in such a way that the support heads are positioned as adjacent as possible to the second connection edge. This means that if the horizontal beam has two or more longitudinal edges or longitudinal beams, the support head is preferably positioned on the longitudinal edge or longitudinal beam that runs closer to the second connection edge.

It is also advantageous if the second number of support heads have a second receiving area on which at least one of the horizontal supports running in the second plane can be fixed.

The second receiving area is preferably positioned vertically below the first receiving area in such a way that a horizontal support inserted into the second receiving area runs in the second plane below the first plane. The second receiving area of the second number of support heads is preferably configured identically to the second receiving area of the first number of support beams, so that one or two horizontal supports can be suspended there. Although the function of the second receiving areas is preferably identical, the configuration or the appearance of the components can differ.

The second number of support heads is preferably positioned on one of the horizontal beams running in the first level in such a way that one of the horizontal beams on the second level, which is hung on the support head, is as close as possible to the building column or rests against it when of the horizontal beams has been swung up into the concreting position.

The second number of support heads is preferably positioned on the horizontal beam running in the first plane in such a way that the support heads are secured against lateral displacement.

It is advantageous if the horizontal supports have support head positioning receptacles which extend at least along a section of at least one of the longitudinal edges of the horizontal support and which are designed to accommodate a support head in a form-fitting manner.

The second receiving area of the support heads can preferably be designed in such a way that two horizontal beams can be hung side by side in the receiving area. Provision is preferably made for each horizontal support to be fixed to two support heads, preferably in such a way that each horizontal support occupies one half of the receiving area of a support head.

The second number of prop heads, which engage a horizontal beam running in the first plane, are preferably supported by a ceiling prop.

According to the invention, it can be provided that the at least one receiving device for fixing the stop-end formwork has a receiving shoe whose orthogonal distance from the vertical support can be adjusted and fixed.

It has proven to be particularly suitable if the receiving device has a fastening element which is connected to the vertical support and is preferably designed as a bore, bushing or sleeve. However, the fastening member can also be designed as a bolt. The fastening member is preferably non-detachably connected to the vertical support, preferably welded. The receiving shoe can preferably have a complementary configuration, for example a spindle, rod or bolt which can be inserted into the bore, bushing or sleeve, or can have a sleeve-shaped connecting member which can be pushed onto a bolt if the fastening member is used as a Bolt is formed. The receiving shoe is preferably detachably connected to the attachment member.

Provision is preferably made for the position of the receiving shoe to be adjustable relative to the fastening element and thus also relative to the vertical support. The setting can preferably be done in a grid or continuously. It is preferably provided that the distance can be changed in the horizontal direction and thus orthogonally to the extent of the vertical support, so that a stop-end formwork that can be fastened using the receiving shoe can be changed in its position in a direction orthogonal to the vertical support.

Before installing the stop-end formwork, the receiving shoe is preferably positioned accordingly, for example in a grid of 1 cm to 2 cm, in particular 1.5 cm, if the distance to the edge of the ceiling to be cast should not fit.

The fixation of the receiving shoe on the fastening element can preferably take place via a cotter pin, in particular a linch pin, or in another way, for example with the aid of nuts.

To adjust the receiving shoes, the cotter pins can then be unlocked from the receiving shoe, the desired distance can be set and the changed position can then be locked again with the cotter pins. If nuts are used for adjustment, they can be screwed onto a spindle, for example, in order to adjust the position.

In a particularly preferred embodiment, it can be provided that the receiving shoe has a spindle whose longitudinal axis, when the receiving shoe is installed as intended, extends in a direction orthogonal to the vertical support. It can be provided that the vertical support has a through hole, which can be provided by a sleeve, for example. The spindle can be passed through this through hole. Two nuts are preferably provided, which are preferably an adjusting nut and a lock nut.

An embodiment of the receiving device such that it has a spindle and two nuts (locking nut and adjusting nut) for setting a horizontal distance between the receiving shoe and the vertical support enables a particularly advantageous stepless adjustment of the distance. The desired position of the receiving shoe can be set quickly and fixed reliably.

In this embodiment, the through hole, which is preferably designed as a sleeve, represents the fastening element.

It is advantageous if the at least one vertical support has a plurality of receiving devices arranged vertically one above the other. It has proven to be suitable if the vertical support has a plurality of receiving devices arranged vertically one above the other, ie the vertical support has a plurality of receiving devices offset along its longitudinal axis. This configuration provides several attachment points for the stop-end formwork, so that stop-end formwork of different heights can also be fixed in a suitable manner. It is advantageous if the vertical support has at least two, preferably three, four or five receiving devices arranged vertically one above the other.

It can be advantageous here if not every receiving device has a receiving shoe, but rather a receiving shoe, each adapted to the end formwork to be fixed, is mounted only in some of the fastening members of the receiving devices.

It can be advantageous if only two receiving devices have a receiving shoe or if a receiving shoe is inserted and fixed in only two fastening members of the receiving devices.

In particular, it can be provided that the vertical supports have at least two, preferably three, four or five fastening members, which are provided in particular by through holes or sleeves, but only some of the fastening members serve to fix a receiving shoe or are part of a receiving device.

It is advantageous if the receiving devices or the fastening members are arranged vertically one above the other at a grid spacing of 10 cm to 20 cm, in particular 15 cm. It can be provided that a lowermost receiving shoe or a lowermost fastening element is inserted or arranged at a distance of 15 cm above the lower end of the vertical support facing the horizontal support.

Due to the fact that the vertical supports have a plurality of fastening elements, it can also be taken into account whether the vertical support is arranged on a horizontal support which runs in the first plane or in the second plane. If the vertical support is arranged on a horizontal support which runs in the second plane, at least the lowermost attachment member will typically not be occupied by a receiving shoe.

For slab thicknesses of 20 to 30 cm, ie if the slab to be cast has a height of 20 to 30 cm, it can preferably be provided that, in the case of a vertical support which is fixed to a horizontal support on the first level, the two lowest fixing members are fitted with a receiving shoe are provided and thus serve as a receiving device. Furthermore, with this slab thickness it can be provided that with a vertical beam that is attached to a horizontal beam of the second level, the second lowest and the third lowest fastening members are provided with a receiving shoe. With a slab thickness that is greater than 30 cm, in particular with a slab thickness of 35 to 40 cm, provision can be made for a vertical beam that is connected to a horizontal beam on the first level to be provided with a receiving shoe on the bottom and the third-bottom fastening element are. Correspondingly, it can be provided that, in the case of a vertical support that is connected to a horizontal support of the second level, the second-lowest and the fourth-lowest fastening element are provided with a receiving shoe.

For the production of slabs with a slab thickness of 20 to 40 cm, it can be particularly suitable if the vertical supports have four fastening members arranged one above the other, which are preferably fitted with receiving shoes, as described above. The vertical beams, which are connected to the horizontal beams of the first and the second level, are preferably of identical design and are only equipped with receiving shoes at different positions.

According to the invention, it can be provided that a substructure, preferably a beam running in the horizontal direction, for the stop-end formwork can be fixed to the receiving shoe.

It is advantageous if two or more than two locating shoes are fixed to each vertical support and each of the locating shoes accommodates a substructure, preferably a beam running in a horizontal direction, for the stop-end formwork. It is preferably a wooden beam. For this purpose, the pick-up shoes are preferably designed as wooden pick-up shoes. It is particularly useful when the pick-up shoes are designed to pick up a wooden beam with a cross-section of 100 x 100 mm. The stop-end formwork can then be fixed to the wooden beam.

According to the invention, it can preferably be provided that the receiving devices and the fastening members are arranged below half the height of the vertical support. This has turned out to be particularly suitable for reasons of stability.

It is advantageous if the at least one vertical support is designed as an outer post.

A design of the vertical support such that it serves both to fix a stop-end formwork or a substructure for a stop-end formwork and as an outer post has proven to be particularly suitable. In order to form the vertical support as an outer post, it can be provided that the vertical support has a plurality of holders for side paneling vertically above the receiving devices, ie in the longitudinal direction of the vertical support above the receiving devices. This can preferably be L-shaped brackets in which Side planking can be used from above. Two or more, in particular three brackets are preferably provided for a corresponding number of side skins.

The vertical support can preferably be a tube, in particular a polygonal tube, particularly preferably a square tube, which can have struts or reinforcements in the lower area.

It is advantageous if the vertical support is connected to an associated horizontal support before it is swiveled up from the assembly position into the concreting position. In this way, the vertical support can be pivoted together with the horizontal support into the intended final position.

It is particularly advantageous if the height of the stop-end formwork or the ceiling thickness is set before the vertical support is installed or at least before the vertical support is pivoted up together with the horizontal support. This is preferably done in that the receiving shoes are connected to the corresponding fastening element or inserted into it, depending on the thickness of the ceiling.

According to the invention, it can also be provided that the horizontal supports are designed as support strips and/or as support frames.

It has turned out to be particularly suitable if the horizontal supports are designed as support strips and/or as support frames. It is particularly preferable if the horizontal supports are designed both as support strips and as support frames.

In the context of the invention, a carrier strip is preferably to be understood as an element which is essentially formed by a strip or a longitudinal carrier, ie an element which extends essentially in the longitudinal direction.

In the context of the invention, a carrier frame is preferably to be understood as an element which has a greater width than the carrier bar, ie has an extension orthogonal to the longitudinal axis which is greater than the corresponding extension of the carrier bar in this direction. However, it is also provided for the support frame that the extent in the longitudinal direction is significantly greater, preferably at least three times as large, as the extent in the width direction.

The carrier frame can preferably have at least two longitudinal members and at least two cross members connecting the longitudinal members.

The support frame preferably has two longitudinal supports and more than two cross supports, in particular more than three cross supports, preferably four, five or six cross supports. In the context of the invention, it is preferably provided that the length of the carrier strips and the carrier frame is identical.

The carrier strip and the carrier frame preferably have a length of 1,500 mm to 2,500 mm, preferably 1,800 mm to 2,100 mm, in particular 1,940 mm. The carrier frame preferably has a width of 250 mm to 1,000 mm, in particular 250 mm to 400 mm, more preferably 300 mm to 400 mm, in particular 340 mm. The above values are measured from the center axis to the center axis of the two beams.

Due to the fact that the horizontal supports are designed both as support strips and as support frames, the circumstances when constructing an outside corner can be addressed in a particularly advantageous manner. It is thus possible to take the position of the building column into account and, for example, to use one, two, three or more support frames, which are positioned in a first plane, together with a support strip, so that, for example, the distance between a first connection edge and an opposite end of the Outside corner or the position of a building pillar, can be set or filled out particularly well.

The horizontal beams can be selected and positioned accordingly in the second level, so that the available space in the second level can also be filled with the horizontal beams as completely as possible or without large gaps.

Within the scope of the invention, it is also possible that only horizontal supports that are designed as support frames are used, or only horizontal supports that are designed as support strips are used.

The use and the number and the arrangement of the support strips or the support frame can be different in the first and the second level, in particular depending on the position of a building column.

In a particularly advantageous embodiment of the invention, it can be provided that at least one of the support frames and at least one of the support strips has connecting members in order to fix the support strip to the support frame laterally and at a distance from a longitudinal member of the support frame, such that the surfaces of the support strip and the support frame run plane-parallel in one plane.

At the same time, this configuration ensures that the longitudinal axis of the at least one carrier bar and the longitudinal axis of one of the longitudinal carriers are arranged parallel to one another. It has turned out to be particularly suitable if the support frames and the support strips are designed in such a way that they can be connected to one another, as a result of which the lateral extension of the support frames can be increased further. The carrier bar is preferably connected to the carrier frame in such a way that the axial ends of the carrier frame and the carrier bar lie in one plane, so that the carrier frame is lengthened laterally, i.e. in width, without an overhang occurring in the longitudinal direction. It is of particular advantage if the carrier frame and the carrier bar can be connected to one another in such a way that the distance between the carrier bar and a longitudinal edge of the carrier frame, in particular a longitudinal member of the carrier frame, can be adjusted steplessly or in a grid. It is thus possible to position the carrier strip in such a way that the surface of the outer corner, which is predetermined by the circumstances, can be filled out as evenly as possible, for example from a first connection edge to a building pillar, in particular with as few large gaps as possible.

It is advantageous if the connecting members of the carrier bar are designed as sleeves and the connecting members of the carrier frame are designed as rods, with the rods being able to be inserted into the sleeves and the position of the rods being able to be fixed relative to the sleeves.

In principle, the connection between the carrier strip and the carrier frame can be made in any way. However, it has turned out to be particularly advantageous if the carrier strip has sleeves or also bores, which are also regarded as sleeves within the scope of the invention, and the connecting members of the carrier frame are designed as rods. Each carrier strip preferably has at least two sleeves, for example two, three, four or five sleeves, which can be connected to a corresponding number of rods of a carrier frame.

According to the invention it can be provided that the position of the rods can be adjusted relative to the sleeves, preferably in steps or in a predetermined grid. As a result, the distance between the carrier bar and the carrier frame can be adjusted in a particularly advantageous manner.

According to the invention it can also be provided that the rods can be pulled out of the support frame and the position of the rods can be fixed relative to the support frame.

In principle, it is possible to store the rods separately from the support frame and to connect them to the support frame if necessary. However, it has turned out to be particularly suitable if the support frame is designed in such a way that the rods can be pulled out of the support frame. The rods can preferably be accommodated in the crossbeams of the support frame and can be pulled out of them. For this purpose, the crossbeams can have corresponding, preferably tubular, areas. It is advantageous if the rods can be pulled out of the support frame and the position of the rods can be fixed relative to the support frame, in particular relative to the cross member.

It is thus possible to pull the rods as far out of the support frame, in particular the crossbeams, as is advantageous given the circumstances. The front ends of the rods are then inserted into the corresponding sleeves of the carrier strip and also fixed there. The fixation can preferably take place via split pins, in particular via linchpins.

It is advantageous if the support rails are mounted on the support frame or connected to them before the support frame is pivoted up from the mounting position into the concreting position. Thus, the pair consisting of a support frame and a support bar can be swiveled up together into the concreting position.

In order to be able to reliably mount a carrier strip on a carrier frame, it is preferably provided that the carrier strip and the carrier frame are first placed next to one another, preferably using trestles. Then the fixations, preferably lynch pins, are removed from the support frame so that the rods placed therein, which are preferably bolt rods, can be pulled out. The fixings, in particular the linch pins, are then removed from the carrier bar and the rods are pushed through the sleeves of the carrier bar. After pushing through the rods or inserting the rods into the sleeves of the carrier bar, the fixation or the linch pins are reattached to the carrier bar in such a way that the rods are fixed relative to the sleeves.

After the bars are secured in the sleeves, the desired distance between the support bar and the support frame can be adjusted. The rods are then fixed or secured relative to the support frame, preferably with the fixations, in particular with the aid of the linch pins.

The rods preferably have transverse bores arranged in a grid, which serve both to attach the rods to the sleeves, preferably using the fixations, in particular the linch pins, and to determine the position of the rods relative to the support frame, preferably also using the fixations, in particular of linch pins to fix or secure.

The carrier frame and the carrier bar are preferably made of aluminum. The bolt rod is preferably made of steel. The bolt rod is preferably 200 mm to 400 mm, in particular 250 mm to 350 mm, particularly preferably 290 mm to 310 mm, extendable from the support frame.

A pair formed by the carrier frame and the carrier bar is also referred to below as an extended carrier frame. The distance between the carrier frame and the carrier bar of an extended carrier frame is preferably 200 mm to 400 mm, in particular 250 mm to 350 mm, particularly preferably 300 mm.

The expanded support frame can be, for example, the first horizontal support, which is swung up into the first or second level. However, the expanded support frame can also be the second horizontal support, which is pivoted up into the same plane adjacent to the horizontal support that was pivoted up first. Likewise, it can also be provided within the scope of the invention that the extended support frame is a third, fourth, fifth, etc. horizontal support that is swung up. The horizontal beams that have been swung up in front of the extended support frame can preferably be support frames. The task of the extended support frame is primarily to close a gap to an outer edge of the outer corner of the ceiling formwork or to a building pillar as far as possible or to ensure that the gap does not exceed a defined distance of preferably a maximum of 300 mm. The gap or distance is measured in the first or second plane in a direction orthogonal to the longitudinal axis of the particular horizontal beam positioned in the plane. The above values are important to prevent people from failing.

It is advantageous if the first axial end of the extended support frame is supported by three support heads, with two support heads supporting the support frame and one support head supporting the support bar or the elements being correspondingly fixed in the support heads.

If a support frame has already been swiveled up before the extended support frame is installed, it is preferably provided that a longitudinal support of the extended support frame is inserted into the same support head in which a longitudinal support of the previously swiveled up support frame is already inserted, i.e. the two are attached to each other Adjoining longitudinal beams of the two support frames share a support head. Furthermore, it is preferably provided that a separate support head and thus preferably also a separate ceiling support supports the second longitudinal member of the carrier frame, which runs adjacent to the carrier strip, or the second longitudinal member is fixed there. Furthermore, a third support head is preferably provided, in which the support strip of the extended support frame is fixed. The slab props for the second and the third support head are adjusted to the position of the second longitudinal beam or the support strip. The extended support frame is preferably provided with a vertical support or is detachably connected.

After pivoting up into the concreting position, the extended support frame is preferably supported by at least one further support head, which engages in the area of the second axial end of the extended support frame. It should be noted that the support head or heads that support the second axial end can have a relatively simply designed surface which is essentially intended to engage in the horizontal support in order to support the pivoted-up horizontal support, for example a support frame, a support bar or also an extended support frame.

Within the scope of the invention, it can be provided that the second axial end of each pivoted-up horizontal beam is supported by its own support head or its own ceiling support. If the first horizontal beam pivoted up and the second horizontal beam pivoted up are support frames, it is preferably provided that the support head or the ceiling support, which is provided for supporting the second axial end of the second horizontal beam, is preferably positioned in such a way that the support head also supports the second axial end of a horizontal support that is pivoted up first. The support head is preferably positioned so that the two adjacent longitudinal beams of the two horizontal beams, which can for example be support frames, are supported by the same support head. Correspondingly, a third support head, which is intended to support a third horizontal beam, and each additional support head for additional horizontal beams can be positioned.

In the context of the invention, it is preferably provided that with an extended support frame, the support bar of the extended support frame and the longitudinal member of the support frame, which runs adjacent to the support bar, are each supported or braced by their own support head or a corresponding ceiling support.

The support heads of the first number and the second number as well as the support frames and the support strips are preferably designed in such a way that both the support frames and the support strips can be fixed to the support heads of the first number and the support heads of the second number.

Within the scope of the invention, it can be provided that, depending on the positioning, a longitudinal member of a support frame rests centrally on a support head or preferably only occupies 50% of the width of the support head, so that the support head can accommodate one longitudinal member of two adjacently positioned support frames.

According to the invention, it can also be provided that for the connection of two horizontal supports positioned side by side and running plane-parallel to one another in one plane, in particular for the connection of two support strips or for the connection of a support strip to a support frame, a bracing adapter is provided which connects the two horizontal supports in the area of their connects first axial ends to one another, with the guying adapter having a starting point, in particular a guying eyelet for fixing a guying chain or a lashing strap. It has been shown that it can be advantageous to combine two carrier strips to form a pair of carrier strips. The pair of carrier bars is arranged in such a way that the two axial ends of the carrier bars each lie in one plane and the surfaces of the carrier bars also run in one plane. The carrier strips of the pair of carrier strips preferably run parallel and at a lateral distance from one another.

It has been found to be particularly advantageous if a bracing adapter is provided to connect two support strips to form a pair of support strips or to connect a support strip to a support frame. The anchoring adapter connects the two carrier bars or a carrier bar and a carrier frame to one another in the area of their first axial ends. The guying adapter has a starting point, in particular a guying eyelet, for fixing a guying chain.

This results on the one hand in a good connection between the two support rails or between one support rail and one support frame, and on the other hand the guying adapter enables the pair of support rails or the extended support frame to be swiveled up together, easily and safely into the concreting position.

Provision can be made for the two carrier bars or the carrier bar and the carrier frame to be additionally connected to one another with the aid of further connecting members, in particular sleeves and rods. However, this is not absolutely necessary. It may be sufficient for the two support rails or the support rail and the support frame to be connected to one another only with the aid of the guying adapter. A corresponding stability of the pair of support rails can be achieved in the concreting position in that corresponding support heads or ceiling supports are placed, preferably in the area of the second axial ends, in order to support the pair of support rails or the extended support frame.

It has turned out to be particularly suitable to fix a guy chain in the attachment point, in particular the guy eyelet. In principle, however, it is also possible to use another anchoring element, for example a tension belt, for anchoring.

According to the invention, it can be provided that the two horizontal beams, which are connected to one another by means of the guying adapter, run in the same plane and are fixed in different, preferably adjacently positioned support heads.

The guying adapter can preferably be designed in such a way that it has a rod or several rods, in particular two rods, with fixations that enable the rod or rods with the two support strips or a support strip and a support frame to be connected steplessly or in a grid connect to. For this purpose, it can preferably be provided that the rod or the rods pass through corresponding bores or sleeves in the carrier strips or the carrier frame are inserted, in particular in such a way as has already been described with respect to the bolt rods. The desired position can then be fixed with the aid of fixations, for example cotter pins, in particular linchpins. The rod or rods of the guy adapter can or can preferably have suitable transverse bores for this purpose, which are preferably arranged in a grid.

Instead of one rod, the anchoring adapter can preferably have two parallel rods. This has turned out to be advantageous for reasons of stability. The function remains the same.

On the rod or rods of the guy adapter, the attachment point, in particular a guy eyelet, is attached, preferably in the middle, for fixing a guy chain. The starting point can be formed, for example, by providing two mutually parallel plate-shaped elements which extend away from the rod or rods in a direction orthogonal to the longitudinal axis of the rod or rods, with the front ends of the two plate-shaped elements are connected to each other by means of a bolt, to which the tensioning chain can then be fixed.

It is advantageous if at least one of the crossbeams has a recess, in particular an opening, for attaching a swivel-up aid.

It has turned out to be particularly suitable if the crossbeams are designed to enable or simplify the attachment of a swivel-up aid. For this purpose, the cross members can preferably have a recess, in particular an opening. The opening may preferably be of a size which also allows it to be gripped with one hand.

The recess for attaching an upward pivoting aid, in particular a formwork aid, is preferably arranged on one of the crossbeams that run in the area of the second axial end. Preferably, the recess for attaching a swivel-up aid is formed on the cross member, which runs adjacent to the second axial end of the support frame. Provision can also be made for several cross members to be provided with corresponding recesses.

According to the invention, it can also be provided that at least one of the support frames has a bracing element with a starting point for fixing a bracing chain in the region of its first axial end.

It has proven to be particularly suitable if at least one of the support frames, preferably all support frames or generally all horizontal supports are designed in the area of their first axial ends in such a way that a starting point, preferably a guy eyelet for fixing a guy chain, is formed. It can also be provided that two starting points, in particular two anchoring eyes, are designed so that two anchoring chains can be fixed to a support frame.

According to the invention, at least one height-adjustment element can be provided, the height-adjustment element being connectable to at least one of the horizontal supports running in the second plane in such a way that a surface of the height-adjustment element provided for attaching the ceiling formwork panel runs in one plane with the surfaces of the ceiling formwork panel provided for attaching it first level running horizontal beams.

It has been shown that it is advantageous if a height adjustment element is used which is connected to the horizontal beams running in the second plane and which has a corresponding height such that a surface of the height adjustment element intended for attaching the ceiling formwork panel is in one plane runs with the surfaces of the horizontal beams running in the first level provided for attaching the ceiling formwork panel. The height adjustment element or elements thus make it possible to compensate in a simple manner for the surfaces of the horizontal beams that run in the second plane to have a vertical distance from the plane in which the ceiling formwork panel is positioned.

The height compensation elements make it possible for the horizontal beams, which are arranged in the first level, to be of identical design to the horizontal beams, which run in the second level. It is therefore not necessary to keep different horizontal supports for each of the two levels, but the same horizontal supports can be used in both levels.

Depending on the circumstances, the height adjustment elements can be attached to a corresponding position on the horizontal beams. The height compensation elements are preferably positioned in such a way that they run orthogonally to the longitudinal axes of the support strips or the longitudinal axes of the support frames. The height adjustment elements thus run plane-parallel to the crossbeams of the support frames. The height adjustment elements can be positioned in any way on the surface of the horizontal support, in particular the surface of the support frame and/or the support rails of the second level.

It has turned out to be particularly advantageous if the horizontal supports or the support frames and the support strips have nail strips, which can preferably be displaced along the longitudinal axes of the horizontal supports.

It is also advantageous if the height compensation elements are designed in such a way that they can be fastened in the nail strips of the horizontal supports or the support strips with the aid of nails.

In one embodiment, the height compensation elements can also have nail strips. The nail bar is preferably made of synthetic material or plastic.

In a particularly advantageous embodiment, it can be provided that the nail strips of the support strips or the support frame can be displaced along the longitudinal axis of the support frame or the support strips, so that the nail strips can be brought into a position in which the height compensation elements are to be fixed.

It has turned out to be advantageous for all horizontal supports if they have nail strips, it being advantageous if in particular the nail strips of the horizontal supports are displaceable, as already explained above. The movability of the nail strips not only has advantages for fixing the height adjustment elements on the horizontal beams, which are positioned in the second level, but is also advantageous for fixing the ceiling formwork panels, which are also nailed to the nail strips of the horizontal beams, which run in the first level. can be connected.

The nail strips can preferably be pulled out of the horizontal beams and replaced. The horizontal supports preferably have grooves in which the nail strips can be moved. In particular, it can be advantageous if the longitudinal supports of the support frame or the support strip have corresponding grooves within which the nail strips can be moved.

The fixing of a height compensation element is shown below by way of example using a horizontal support, which is designed as a support frame. For this purpose, the support frame can preferably be placed on a trestle and the height compensation element positioned in such a way that the height compensation element is in the desired position after the support frame has been swiveled up, for example positioned in such a way that after the support frame has been swiveled up, the height compensation element runs approximately flush with the edge of a building .

It is advantageous if the height adjustment elements can be pulled out in order to change the extent of the height adjustment elements along their longitudinal axes.

Because the height adjustment elements can be pulled out, their position can be optimally adjusted.

It is advantageous if a head part of the height compensation elements is designed in such a way that the head part can be brought into engagement with one of the support heads.

It has proven to be advantageous if the front, axial, extendable end of the height adjustment elements, ie the head part, is designed in such a way that it can be inserted into the first number and the second number of support heads. The fact that the head part of the height adjustment element can be connected to an adjacent support head results in additional stability or additional support for the ceiling formwork panel.

Insofar as two horizontal beams, which are each provided with a height adjustment element and which are then to be connected to one another, are pivoted up separately, the height adjustment elements should preferably be mounted in such a way that they do not collide with one another when pivoted up.

The height adjustment element is - as described - preferably fixed by nails on the support frame or the support bar. If the nail bar is not in a position in the carrier frame or in the carrier bar in which the height adjustment element is to be attached, the nail bar can be moved accordingly. The position of the nail strip can preferably be fixed by screws relative to the carrier frame or the carrier strip, in particular in a rail or a groove of the carrier frame or the carrier strip. For this purpose, the screws are preferably screwed into the side members or orthogonally to the longitudinal members in order to fix the nail bar in the desired position.

As an alternative or in addition to the height adjustment elements, squared timbers of a suitable height can also be used in order to bridge a distance between the surface of the horizontal beams on the second level and the surface of the horizontal beams on the first level. The squared timber can be connected accordingly with the nail strips of the horizontal beams, which run in the second level.

The horizontal beams are preferably positioned to form an outside corner of the slab formwork in such a way that the gaps between two horizontal beams are less than or equal to 300 mm.

This construction creates such a small grid of openings (due to the grid-like structure of the horizontal beams when several of the horizontal beams are arranged orthogonally) that no workers can fall through from above and safety is significantly increased. This is particularly important if the outside corner is constructed from below and the formlining is laid onto the grid-like structure from above.

According to the invention, it is preferably provided that at least two horizontal beams are arranged in each of the two planes. It is advantageous if the horizontal beams running in the second plane are supported by support heads or floor props in the same way as the horizontal beams running in the first plane.

According to the invention, it can be provided that the horizontal supports, in particular the support strips and the support frames, are provided with anchoring eyelets in which anchoring chains can be fixed.

According to the invention, it can also be provided that after all horizontal beams have been swiveled up and after all support heads or ceiling supports have been set, a fall protection device, in particular side planking, as well as the ceiling formwork panel and the end formwork can be installed. The side paneling or the fall protection can preferably be pushed into the corresponding receptacles of the vertical beams, preferably from the side or from above.

It is advantageous if the substructure, in particular the beams for the stop-end formwork, are pushed in laterally far enough for each beam to be supported by at least two mounting shoes, each of which is assigned to a vertical support. Preferably, at least two beams are positioned vertically one above the other for each stop-end formwork, correspondingly in receiving shoes.

The receiving shoes are preferably U-shaped or designed as U-receptacles. The beams are preferably fixed on one side in the receiving shoes, preferably with nails.

The ceiling formwork panel is cut in a basically known manner, in particular in such a way that it takes into account the position and the shape of a building column. The ceiling formwork panel is then fixed to the nail strips of the horizontal beams with nails.

The beams for the stop-end formwork and also the side paneling or the side protection boards are preferably only fixed with nails in the respective receptacles when the ceiling formwork panel is fixed to the nail strips.

A fine adjustment of the substructure, in particular the beams for the stop-end formwork, can then be made if the distance to the planned edge of the slab is not yet correct. After the distance has been set, the stop-end formwork, in particular the formlining, is installed and preferably fixed to the substructure or the beams with nails or screws. To adjust the end formwork it can be provided that after the beams have been set, in particular in a grid dimension, wedge angles, in particular wooden wedge angles, are then hammered in between the beams and a bottom of the receiving shoes for fine adjustment. As a result, the distance between the stop-end formwork and the vertical beams can be changed again and the distance to the edge of the slab can be readjusted again. The stop-end formwork can be dismantled in reverse order. The same applies to the dismantling of the beams and the side paneling as well as the dismantling of the horizontal beams.

The device according to the invention is suitable both for constructing an outside corner in which the structural pillar is indented and for constructing an external corner in which the structural pillar is positioned directly at the edge, for example also in a corner of the building ceiling. Differences can arise in the positioning of the floor props or the support heads.

The device according to the invention enables the construction of an outside corner regardless of the position at which the building column is positioned in the area of the outside corner.

The device according to the invention for constructing an outside corner is of course also suitable if no building pillar runs in the area of the outside corner.

Provision can optionally be made for two floor supports to be connected to one another in the lower area by a squared timber, for which purpose known bracing clamps can be used.

The present invention also relates to a slab form comprising a plurality of slab panels supported and held in position by props, an outside corner of the slab form being made by means of an apparatus according to any one of claims 1 to 25.

The present invention also relates to a horizontal beam, a support head, a height adjustment element and a bracing adapter for a device for producing an outer corner of a ceiling formwork according to one of Claims 1 to 25.

The present invention also relates to a method for constructing an outer corner of a ceiling formwork, in particular in an area in which a building column runs, according to which at least a first ceiling panel and a second ceiling panel are arranged in such a way that a first connecting edge and a second connecting edge running orthogonally thereto of the outer corner are formed, after which a plurality of horizontal beams positioned and at least one ceiling formwork panel is placed.

According to the invention, it is provided that a plurality of support heads are positioned, after which a first axial end of the horizontal beam is detachably fixed to one of the support heads and pivoted up from an assembly position to a concreting position, in which a longitudinal axis of the horizontal beam runs plane-parallel to the floor formwork, wherein a first number of support heads are positioned adjacent to the first connection edge and a second number of support heads are positioned adjacent to the second connection edge, and wherein a first number of horizontal beams are fixed to the first number of support heads and run in a first plane in the concreting position, wherein the Longitudinal axes of the first number of horizontal beams extend in a first direction starting from the first connection edge and a second number of horizontal beams are fixed to the second number of support heads and run in a second plane in the concreting position, with the two planes running plane-parallel to one another and the second plane runs below the first plane, and wherein the longitudinal axes of the second number of horizontal supports extend, starting from the second connection edge, in a second direction which runs orthogonally to the first direction.

It is advantageous if at least one of the horizontal supports is connected to a vertical support and, after the horizontal support has been pivoted up, a stop-end formwork of the outer corner is fixed to the vertical support.

Features that have been described in connection with one of the objects of the invention, namely given by the device, the ceiling formwork, the horizontal beam, the support head, the height adjustment element, the guying adapter and the method, can also be advantageously implemented for the other objects of the invention. Advantages that were mentioned in connection with one of the objects of the invention, namely given by the device, the ceiling formwork, the horizontal beam, the support head, the height adjustment element, the guying adapter and the method, can also be understood in relation to the other objects of the invention .

It should be pointed out that the horizontal supports, in particular in the design as a support strip, as a pair of support strips, as a support frame and as an extended support frame, are newly developed components which, taken on their own, also represent an invention independently of the device according to the invention. in particular with the features shown for the respective elements in Figures 3, 4, 5 and 6. In particular, the way in which a support strip and a support frame are connected is an invention in its own right, both with the aid of the connecting links and with the aid of a bracing adapter.

The device according to the invention, as shown in the exemplary embodiments, preferably has at least two vertical supports 16 . In principle, it is possible to provide each horizontal support 9, 10 with one, optionally also with two, vertical supports 16. However, it has been shown that it is not necessary for each of the horizontal supports 9, 10 to be provided with a vertical support 16. In particular, it can be sufficient if a minimum distance between the vertical supports 16 is greater than 400 mm, in particular greater than/equal to 435 mm.

In particular, it can be sufficient if two vertical beams 16 are positioned on each of the two sides of the outside corners 1, which form an outside corner of the building. The substructure, in particular the beams 22, can thus be fixed in an advantageous manner.

In the exemplary embodiments, it is provided that the at least one vertical support 16 is designed as an outer post.

In the exemplary embodiments, the vertical supports 16 have at least one, preferably at least two, in particular three, side protection receptacles 26 which are intended to accommodate side protection 27 or fall protection.

The side protection mounts 26 are preferably hook-shaped, in particular L-shaped, preferably of the type shown in FIG. Figures 1, 2 and 34 show an advantageous arrangement of the mounted side protection 27. The side protection 27 can preferably be side protection boards, for example with a cross-section of 12 x 4 cm or 15 x 4 cm. It can also be advantageous if two side protection boards 27 are doubled, for example with the dimensions 2×15×3 cm.

In the exemplary embodiments, it is provided that the horizontal supports 9, 10 are preferably designed as support strips 9 and/or as support frames 10.

A particularly advantageous embodiment of a carrier bar 9 is shown in FIGS.

A particularly advantageous embodiment of a support frame 10 is shown in FIGS. 3, 4 and 5.

In a particularly advantageous embodiment, which is also shown in the exemplary embodiments, it can be provided that one of the support frames 10 is connected to one of the support rails 9 . A carrier frame 10, which is connected to a carrier bar 9, is also referred to as an extended carrier frame 28 below. An extended support frame 28 can be used in the same way as a support bar 9 or a support frame 10.

In the figures 15 and 16 a particularly advantageous connection between a support frame 10 and a support bar 9 is shown. For this purpose it is provided that the carrier frame 10 and the carrier strip 9 each have connecting members 29, 30. Using the connecting members 29, 30, the carrier bar 9 can be fixed laterally and at a distance to a longitudinal member 10a of the carrier frame 10 such that the surfaces of the carrier bar 9 and the carrier frame 10 run plane-parallel in one plane. An extended support frame 28 is thus formed in a particularly advantageous manner.

In the exemplary embodiment, it is provided that the connecting members of the carrier strip 9 are designed as sleeves 29 . The connecting members of the support frame 10 are designed as rods 30 or as bolts. The rods 30 are preferably designed in such a way that they can be inserted into the sleeves 29 and the position of the rods 30 relative to the sleeves 29 can be fixed.

In the exemplary embodiments, in particular in FIGS. 15 and 16, a particularly advantageous embodiment of the rods 30 is shown. The rods 30 can be pulled out of the support frame 10 . The extended position of the rods 30 can be fixed relative to the support frame 10 . In order to fix the position of the rods 30 relative to the sleeves 29 or to the support frame 10, provision can be made for the rods 30 to have bores, not designated in any more detail, through which fastening elements, in particular cotter pins 31, can be pushed. For this purpose, the sleeves 29 or the support frame 10 has corresponding bores, not shown in detail, through which the cotter pins 31 can also be passed in order to fix the rods 30 relative to the sleeves 29 or to the support frame 10 .

In the exemplary embodiment, it is provided that the support frame 10 has at least one rod 30, preferably at least two rods 30, in particular exactly two rods 30, with the aid of which and with the aid of corresponding sleeves 29 on the support strip 9 an extended support frame 28 can be produced. A possible installation of a correspondingly expanded support frame 28 is shown in FIG.

The use of connecting members 29, 30, in particular in the form of sleeves and rods, to produce an extended support frame 28 has proven to be particularly suitable in the manner shown in the exemplary embodiment. In principle, however, it is also possible to connect a carrier bar 9 and a carrier frame 10 to one another in some other way in order to form an extended carrier frame 28 . In particular, it is also possible to use a rod 30 independently and to connect the rod to the carrier strip 9 or the carrier frame 10, preferably by means of suitable sleeves 29.

However, it has been found particularly suitable if the support frame 10 is designed in such a way that the rod 30 is received in the support frame 10 so that the rod 30 is available at any time in order to produce an extended support frame 28 . In particular, it can be provided that the rod 30 runs in a bore of a cross member of the support frame 10 that is explained in more detail below, especially when the rod 30 is not required to produce an extended support frame 28 .

In the exemplary embodiment, a further advantageous possibility is shown as an alternative or in addition to connecting two horizontal beams 9, 10 to one another. In this regard, reference is made in particular to the illustration in FIGS. 27 and 30.

To connect two horizontal supports 9, 10 positioned side by side and running plane-parallel to one another in one plane, in particular to connect two support strips 9 (see Figure 27) or to connect a support strip 9 to a support frame 10 (see Figure 30), a guy adapter 32 may be provided.

The bracing adapter 32 can be designed as shown in FIG. 11 or preferably as shown in FIGS. 27b to 27e. As shown in the exemplary embodiments, it is preferably provided that the bracing adapter 32 connects two carrier strips 9 or a carrier strip 9 and a carrier frame 10 to one another in the region of their first axial ends, which are intended for hanging on the connection edges 6, 7. The guying adapter 32 has a guying point 33, in particular a guying eyelet, for fixing a guying chain 34.

Two carrier strips 9 connected to one another are also referred to below as a pair of carrier strips 35 .

A bracing adapter 32 is shown as an individual part in FIG. A particularly advantageous bracing adapter 32 is shown as an individual part in FIGS. 27b to 27e.

However, the exemplary embodiment is not limited to such a design of the bracing adapter 32 .

The design of the guying adapter 32 with a guying point, in particular a guying eyelet 33, makes it possible in a particularly advantageous manner to attach one of the guying chain 34 in order to be able to swing up the pair of support rails 35 or the extended support frame 28 safely from an assembly position into the concreting position. Corresponding anchoring chains 34 are shown in the exemplary embodiments, for example also in FIG. 28 and in FIG. 29, in which a pair of support rails 35 is shown in the assembly position (FIG. 28) and the concreting position (FIG. 29).

FIGS. 31 and 32 show the expanded support frame 28 shown in FIG. 30 with a bracing adapter 32 in the concrete position. A bracing adapter 32 according to FIG. 11 is shown, but it can preferably also be a bracing adapter 32 according to FIGS. 27b to 27e.

FIG. 32 shows a finished construction of horizontal supports 9, 10, with a support frame 10 and a pair of support strips 35 running in the first plane 14 and a support frame 10 and a support strip 9 being arranged in the second level 15. Instead of a support frame 10 and a support strip 9, an extended support frame 28 could also be arranged if necessary.

In the exemplary embodiments, it is provided that the horizontal beams 9, 10, which are connected to one another by means of the guying adapter 32, are fixed in different, preferably adjacently positioned support heads 11, 12 in the first plane. For this purpose, reference is made to the illustration in FIGS. 29, 31 and 32 as an example.

The support heads 11, 12, the support frames 10 and the support strips 9 are designed in the exemplary embodiments such that both the support frame 10 and the support strips 9 on the support heads 11, 12 can be set. This means that the support heads 11 , 12 are designed both to fix the support frame 10 and to fix the support strips 9 .

As already mentioned, FIGS. 3 to 5 show a particularly advantageous structure of a support frame 10. For this purpose, it is provided that the support frame 10 has at least two, preferably exactly two, longitudinal supports 10a and at least two cross supports 10b connecting the longitudinal supports 10a.

In the exemplary embodiment, it is provided that a carrier frame 10 has three to eight, preferably four to six, crossbeams 10b. The cross member 10b can be designed differently. It can be provided that a portion of the cross member 10b has bores for receiving connecting members for producing an extended support frame 28, in particular for receiving rods 30 and bolts. Furthermore, part of the crossbeam can have a recess 36, in particular an opening, for attaching a swivel-up aid (not shown) in order to swivel the support frame 10 from an assembly position into the concreting position.

FIGS. 3 to 5 show in detail a further advantageous, fundamentally optional embodiment, in which a bracing element 37 with a starting point for fixing a bracing chain 34 is provided in the area of the first axial end of the support frame 10 . Analogous to the anchoring point 33 of the anchoring adapter 32, one of the anchoring chains 34 can be attached to the attachment point in a particularly advantageous manner.

The horizontal beams 9, 10 shown in the exemplary embodiments have supporting head positioning receptacles 38 in a particularly advantageous manner. A support head 11, 12 can be positively accommodated with the aid of the support head positioning receptacles 38. A relative displacement of the support head 11, 12 along the longitudinal axis of the horizontal beams 9, 10 is thus avoided or largely avoided by the support head positioning receptacles 38. The support head positioning receptacles 38 preferably extend, as shown in Figures 3 to 7, along a section of the longitudinal members 10a of the support frame 10 or along a section of the support strip 9. In the exemplary embodiment, it is provided that the support head positioning receptacles 38 are essentially extend over the entire length of the longitudinal members 10a and the support strip 9. The support head positioning receptacles 38 are positioned in a grid so that a support head 11, 12 can be positioned between two support head positioning receptacles 38.

In the exemplary embodiments, at least one height compensation element 39 is preferably, but optionally, provided. The height compensation element 39 can be connected to at least one of the horizontal beams 9, 10 running in the second plane 15 in such a way that a surface of the height compensation element 39 intended for attaching the ceiling formwork panel 8 runs in one plane with the surfaces of the ceiling formwork panel 8 intended for attaching in the first Level 14 running horizontal beams 9, 10. In a particularly simple embodiment, the height compensation element 39 can be a block or a block, in particular squared timber, as is shown in FIG. 32, for example.

In a particularly advantageous embodiment, however, the height compensation element 39 is designed in the manner shown in FIG. 10 by way of example. However, such a height compensation element 39 is not limited to the precise configuration according to FIG. Nevertheless, a representation as shown in FIG. 10 is particularly advantageous for forming a height compensation element 39 .

In the exemplary embodiment, it is preferably provided that the height adjustment elements 39 can be pulled out in order to change the extension of the height adjustment elements 39 along their longitudinal axes. This is shown by way of example in FIG. In a particularly advantageous manner, it is provided that a head part 40 of the height adjustment elements 39 is designed in such a way that the head part 40 can be brought into engagement with one of the support heads 11, 12. This is shown in FIG. 24, for example.

A particularly advantageous installation of a height compensation element 39 on a horizontal support 9, 10 is shown in FIGS. 19 to 21. FIGS. 19 to 21 show the assembly of a height compensation element 39 on a support element 10. In the same way, however, assembly on an extended support frame 28 or a pair of support strips 35 and, if appropriate, only on one support strip 9 can also be provided.

To mount the height compensation element 39, it can be advantageous if the horizontal supports 9, 10 have nail strips 41. The nail strips 41 are preferably designed in such a way that they can be displaced along the longitudinal axes of the horizontal supports 9, 10. With the aid of nails 42 (see FIG. 21), the height adjustment element 39 can be connected quickly and easily to the horizontal support 9, 10 in the desired position by driving the nails 42 into the nail strip 41 accordingly.

In principle it is possible for any number of horizontal supports 9 , 10 to be arranged in the two levels 14 , 15 . However, it has proven to be advantageous if at least two horizontal beams 9, 10 are arranged in each plane 14, 15, as is shown by way of example in FIG. 2, FIG. 23, FIG. 31, FIG. 33 and FIG . Two horizontal supports 9, 10 can also be connected to one another to form a unit, for example as an extended support frame 28. To support the horizontal beams 9, 10 ceiling supports 13 are used at suitable positions. It can also be provided that ceiling supports 13 are repositioned during the construction process or are only temporarily positioned.

The exemplary embodiment also applies as a disclosure for a ceiling formwork 2, which has a plurality of ceiling panels, in particular also the ceiling panels 4, 5, which are supported by ceiling supports 13 and held in position.

The exemplary embodiment is also intended to serve as an isolated disclosure for advantageous horizontal beams 9, 10, in particular of the type shown in FIGS. 3 to 7. Furthermore, the exemplary embodiment is also intended to disclose a vertical support 16, in particular according to FIG. 12, support heads 11, 12, in particular according to FIGS. 8 and 9, for a height compensation element 39 according to FIG. 10, a bracing adapter 32 according to FIGS. 27b to 27e and a bracing adapter 32 serve according to FIG.

The exemplary embodiment also serves as a disclosure of an advantageous method for constructing an outer corner 1 of a ceiling formwork 2, in particular in an area in which a building column 3 runs, with the features of the method according to the invention.

Individual exemplary embodiments are discussed in more detail below. It should be noted that the exemplary embodiments are to be understood in such a way that the features disclosed in a specific exemplary embodiment are optional on the one hand and can also be used in other exemplary embodiments if necessary.

It should also be pointed out that, even if a feature has been described as advantageous in one exemplary embodiment, this feature does not necessarily have to be present, but only as an option.

In general, it is advantageous to hang a support frame 10 on two support heads 11 or on two support heads 12 that are positioned adjacent to one another. In FIG. 12a, the carrier frame 10 is suspended in an already existing support head 11 of the structure. The second support 11 is placed in such a way that the support frame 10 fits in accordingly. A guy chain 34, as shown in FIG. 14b, is then hung on the guy element 37. The support frame 10 can then be swung up from the assembly position (FIG. 14a) into the concreting position (FIG. 14d). In this case, FIG. 14c shows an intermediate position.

In the assembled position, the vertical support 16, more precisely the fastening element 19 of the vertical support 16, is connected to a corresponding fastening area of the horizontal support 10. For this purpose, the horizontal support 10 can have suitable bores. The exact position is preferably chosen so that there is still enough distance from the outer edge of the building to the receiving shoe 21 for the Forehead formwork 18 is present. The receiving shoe 21 can preferably be a wooden receiving shoe. The vertical support 16 is preferably mounted on the longitudinal support 10a of the support frame 10 of the first level 14 which runs closer to the ceiling panel 5 .

It is advantageous if the height of the stop-end formwork 18 or the ceiling thickness is set in advance before the vertical support 16 is installed. This can be done via the receiving device 17 or the receiving shoes 21 . Depending on the thickness of the ceiling, the receiving device 17 is inserted into the corresponding hole 23 or generally into a suitable guide in the vertical support 16 .

To swivel up the horizontal beams 9, 10, for example the support frame 10, as shown in FIGS. 14a to 14d, the use of a swiveling-up aid, not shown in detail, which is also referred to as a formwork aid, is suitable. After pivoting up (see FIG. 14d), a ceiling support 13 with a support head 12 or another suitable support head can be positioned to support the carrier frame 10. It can be advantageous if the anchoring chain 34 is subsequently tightened. It is advantageous if the upward pivoting aid is attached to the last transverse strut 10b, which faces away from the first axial end of the support frame and preferably has a recess 36 suitable for this purpose. It is advantageous if the swivel-up aid is held in position until a (preferably engaged) support head 12 is positioned accordingly.

In the illustration according to FIG. 14d, in which the carrier frame 10 runs in the concreting position and is supported by support heads 11, 12, provision is preferably made for two anchoring chains 34 to be attached.

Figures 15 and 16 show the assembly of the extended support frame 28. For this purpose, it is preferably provided that a support bar 9 and a support frame 10 are placed next to each other, preferably as shown on trestles not designated in detail. A cotter pin 31, for example a spring clip, can then be removed from the support frame 10 and the rod 30 placed therein, for example a bolt rod, can be pulled out. Correspondingly, a cotter pin 31 on the carrier strip 9 can be removed so that the bolt rod 30 can be pushed through the sleeve 29 of the carrier bar 9 and pinned with the cotter pin 31, for example a linch pin. The desired width of the extended support frame 28 is then preferably set, i.e. the orthogonal distance between the support bar 9 and the facing longitudinal member 10a of the support frame 10 10 to be fixed. The design of the splints 31 or the manner in which the rod 30 is fixed to the carrier frame 10 or the carrier bar 9 can be arbitrary; . By selecting an appropriate Hole in the rod 30, the distance between the support frame 10 and the support bar 9 can be varied.

FIG. 17 shows the expanded support frame 28 in the position for concreting, as it was assembled in FIGS. 15 and 16.

In order to pivot the expanded support frame 28 up from the assembly position into the concreting position, it is preferably provided that a guy chain 34 is positioned centrally on the support frame 10 and is preferably hooked into the guy element 37 . Another anchoring chain 34 is preferably attached to a suitable point, not specified, of the carrier strip 9 in the region of the first axial end of the carrier strip 9, for example a bracket.

It is advantageous if a longitudinal beam 10a of the support frame 10 is suspended in the support head 11, in which the support frame 10 pivoted up first is already suspended. For the second longitudinal beam 10a of the support frame 10 and also for the support strip 9, a separate support head 11 is then positioned with the aid of corresponding ceiling supports 13. The two additional support heads 11 with the ceiling supports 13 are placed in such a way that the second longitudinal beam 10a of the support frame 10 and the support strip 9 fit in accordingly.

The extended support frame 28, preferably the support strip 9 of the extended support frame 28, can be provided with a vertical support 16. The vertical support 16 can be mounted in the manner already described for mounting on a support frame 10 . The carrier strip 9 can have corresponding fastening surfaces, in particular bores.

The extended support frame 28 can be swung up in a manner analogous to that already described with regard to the support frame 10 . It may be advantageous to use a second upward pivoting aid, which is preferably attached to the last or penultimate recess (of the cross member 10b), relative to the end facing away from the first axial end of the extended support frame 28.

After the extended carrier frame has been swiveled up into the concreting position, the extended carrier frame 28 can be supported in the area of the outer edge of the building by ceiling supports or support heads.

It should be pointed out that the horizontal beams 9, 10 pivoted up in the first plane 14 can be supported by conventional support heads. The use of support heads 12, which are designed in such a way that horizontal beams 9, 10 can be hung, which run in the second plane 15, is only necessary at the points where the assembly or hanging of horizontal beams 9, 10, the should run in the second plane 15 is provided. The support heads 12 are preferably designed in such a way that they can be detachably connected to a ceiling support 13, for example using preferably four screws and preferably four corresponding nuts.

The support heads 12 are mounted below the horizontal beams 9, 10, which run in the first plane 14. The support heads 12 are preferably positioned in such a way that a horizontal beam 9, 10, which is hooked into the support heads 12, is as close as possible to a building column 3 (if a building column 3 is present) when the horizontal beam 9, 10 is swiveled up. This is shown by way of example in FIG.

In the embodiment shown in FIGS. 14a to 14d, FIG. 17, FIG. 22 and FIG. 23, the support head 12 is positioned adjacent to the second ceiling panel 5 on the support frame 10 of the first level 14. A displacement of the support head 12 in the longitudinal direction relative to the support frame 10 is prevented by the support head positioning mounts 38 of the support frame 10 .

In the figures 19 to 21 the assembly of a height compensation element 39 is shown. For this purpose, it is provided that a support frame 10 is placed on trestles that are not designated in any more detail. The height adjustment element 39 is positioned on the support frame 10 in such a way that after the support frame 10 has been swiveled up, the height adjustment element 39 is preferably flush with the edge of the building. The height compensation element 39 is fixed to the support frame 10 by the nails 42 . For this purpose, the carrier frame 10 has a nail bar 41, as already described. If the nail bar 41 is not in the desired position in the support frame 10 in which the height adjustment element 39 is to be attached, the nail bar 41 can be loosened, moved laterally and fixed again with screws 43 (see FIG. 20).

The height compensation element 39 is pivoted up together with the support frame 10 .

The support frame 10 shown in FIG. 22, which runs in the second plane 15, can preferably in turn be provided with a vertical support 16, which is connected to the support frame 10 in the manner already described before pivoting up into the concreting position. It is advantageous if the vertical support 16 is connected to the support frame 10 in such a way that the vertical support 16 is positioned as close as possible to the building column 3 when the support frame 10 is swung up into the concreting position.

The carrier frame 10 is hung on two supporting heads which are positioned adjacent to one another in order to be pivoted up. Tensioning chains 34 are preferably used again, as described, accordingly. After the carrier frame 10 has been swiveled up, as shown in FIG. 22, a correspondingly suitable support head, which can be a conventional support head, which is connected to a ceiling support 13, can be positioned and then the swivel-up aid can be removed.

FIG. 23 shows an illustration according to FIG. 22, with a further support frame 10, which is also connected to a vertical support 16, being swung up. The vertical support 16 is fixed to a longitudinal support 10a which is adjacent to the ceiling panel 4 . The second pivoted support frame 10, which runs in the second plane 15, also has a height-adjustment element 39, which is arranged in such a way that the two height-adjustment elements 39 run on the same straight line. Provision can be made here for the head part 40 of the last pivoted-up height-adjustment element 39 to be pulled out and hung in a support head, in particular a support head 11 . The support head 1 1 can be positioned using a corresponding ceiling support 13 after the support frame 10 has been pivoted with the height adjustment element 39 in the concreting position. This is shown accordingly in FIG. 23 and enlarged in FIG.

After the horizontal beams 9, 10 have been placed in the concreting position, as shown in FIG. 23, the fall protection (side protection 27), the ceiling formwork 2 and the end formwork 18 can be installed.

In order to assemble the side protection 27 or the fall protection, it is provided that these are pushed from a safe position into the side protection mounts 26 of the vertical support 16 and then nailed. Then the substructure or the beams 22 of the stop-end formwork 18 is pushed into the receiving shoes 21 and preferably also fixed with nails. In this regard, reference is made to FIG. 2, which shows the assembled side protection 27 and the assembled beams 22. FIG. The ceiling formwork panel 8 is then cut to size and assembled, preferably from formwork panels. Nails are preferably provided, with which the ceiling formwork panel 8 is fixed to the nail strips 41 of the horizontal beams 9, 10, which are located in the first plane 14. After the ceiling formwork panel 8 has been installed, the beams 22 and the side protection 27, in particular the side protection boards 27, can be completely fixed with nails.

The stop-end formwork 18 can then be mounted on the beam 22 and preferably fixed using nails 42 and screws 43 . The result is shown accordingly in FIG.

After the ceiling has been filled, the ceiling formwork panel 8 and the other elements can preferably be removed again in the reverse order. In the figures 27a, 28 and 29 is shown as an example of how two carrier bars 9 are combined to form a pair of carrier bars 35 . This is illustrated by the use of the bracing adapter 32 according to FIG. Alternatively, the bracing adapter 32 according to FIGS. 27b to 27e can also be used for this purpose. In order to mount the bracing adapter 32, sleeves 29 of the carrier strips 9 can be used (or a correspondingly different fastening element which is suitable for fixing the bracing adapter 32). Cotter pins 31 can be provided, in particular tube flap cotter pins, with which the sleeves 29 are provided. The cotter pins 31 can be loosened in order to be able to insert the bracing adapter 32 into the sleeves 29, as shown in FIG.

As shown in FIG. 11, it can be provided that the bracing adapter 32 has a rod 32a with bores 32b, so that the bracing adapter 32 can be connected to the carrier strips 9 in different positions using the cotter pins 31 . The cotter pins 31 can be attached to the carrier strip 9 in or on the outside. For this purpose, the carrier strip 9 has corresponding bores in the sleeves 29 that are not designated in any more detail.

It is advantageous if the guy chain 34 is hung on the guy eyelet 33 of the guy adapter 32 . In addition, a bracing chain 34 can also be hung on the outermost carrier bar 9 or a bracing chain 34 can be hung on both carrier bars 9 . The pair of carrier strips 35 is then swiveled up into the concreting position, resulting in the representation according to FIG. A vertical support 16 is preferably mounted on the support strip 9 of the pair of support strips 35, which runs closer to the edge of the building, before it is pivoted up.

FIG. 30 shows the assembly of an expanded carrier frame 28, in which the carrier strip 9 and the carrier frame 10 are connected to one another using the guy adapter 32 according to FIG. Alternatively, the use of a bracing adapter 32 according to FIGS. 27b to 27e can also be provided here. The installation of the anchoring adapter 32 can be carried out analogously to the installation of the pair of carrier strips 35 already described.

The bracing adapter 32 shown in FIGS. 27b to 27e differs from the bracing adapter 32 according to FIG. 11 in that two rods 32a are provided, which have corresponding bores 32b. It is thus possible to fix the anchoring adapter 32 to two connecting members or sleeves 29 of a carrier strip 9 or a carrier frame 10. Thus, for example, the two sleeves 29 of the two support rails 9 lying at the front in the image direction of FIG. 27a can each be connected to a rod 32a of the bracing adapter 32 according to FIGS. 27b to 27e.

The bracing adapter 32 according to FIGS. 27b to 27e can be used in each of the exemplary embodiments instead of the bracing adapter 32 according to FIG. FIGS. 31 and 32 show the expanded support frame 28 according to FIG. 30 in the concrete position. A vertical support 16 is mounted on the longitudinal support 10a of the support frame 10 of the extended support frame 28 which is closer to the ceiling panel 4 .

FIG. 32 shows the use of a height-adjustment element 39. In FIG. 32, the height-adjustment element 39 is designed as squared timber. However, it can also be a height compensation element 39 according to FIG. If necessary, a cantilevered area of the squared timber can be supported by a ceiling support 13 with a cross head.

The positioning of the support heads 11, 12 in Figures 31 and 32, which are positioned using the ceiling supports 13 (not visible in the figures) after the horizontal beams 9, 10 have been pivoted up, has proven to be particularly suitable, although the ceiling supports 13 can also be positioned elsewhere.

In the exemplary embodiments, the ceiling supports 13 are only partially provided with reference symbols for reasons of clarity. Particularly in the case of the ceiling props 13, which are positioned after the horizontal beams 9, 10 have been pivoted into the concreting position, the design of support heads can be arbitrary, unless it is intended that further horizontal beams 9, 10 should be hung on these support heads for pivoting up. Insofar as the reference numeral 11 or 12 was used, it is a matter of support heads on which horizontal supports 9, 10 are hung for swiveling up and/or support heads into which a first axial end of the horizontal supports 9, 10 is suspended. Such support heads usually also have ceiling supports 13, at the upper end of which the support heads 11, 12 are mounted. For reasons of clarity, however, only the reference number 11 or 12 was used here in most cases.

If necessary, so-called bracing clamps and a squared timber can be used in all exemplary embodiments for positioning the ceiling supports 13, so that the ceiling supports 13 do not fall over before horizontal beams 9, 10 are hung in them.

Figures 1, 2, 14a to 14d, 17, 22 and 23 show the structure of an outer corner 1 based on a situation in which a building pillar 3 is positioned in the corner of the building.

Figures 26, 28, 29, 31 and 32 show the structure of an outside corner 1 when the building pillar 3 is slightly indented from a corner of the building.

The basic structure is identical here.

FIGS. 33 and 34 show the structure of an outer corner 1 of a ceiling formwork 2 when a building column 3 is positioned in the center of the outer corner 1 . FIG. 35 shows a construction of an outer corner 1 of a ceiling formwork 2 when no structural column 3 is provided. In principle, the assembly of the horizontal beams 9, 10, which run in the first and in the second plane 14, 15, can proceed in the same way as was described with regard to an outer corner 1, in which a building column 3 runs in the outer corner 1.

As has already been described, the ceiling formwork panel 8 and the other elements can be mounted on the structure of an outer corner 1 and a ceiling formwork 2 shown in FIG. The same applies to the representation of the embodiments according to Figure 35.
