EP3662116B1 - Ceiling formwork and method for producing a ceiling element - Google Patents

Description

The invention relates to a method for producing a ceiling element.

From the WO 2016/177979 A1 such a ceiling formwork for the production of ceiling or floor panes is already known in which a permanent formwork panel is used. In this state of the art, a number of ceiling supports are initially built on which the longitudinal and transverse beams are supported. The lost formwork panels, with which the ceiling or floor pane is cast, are placed on this structure. The lost shuttering panels form a lower layer of the finished ceiling or floor pane. The use of lost shuttering panels has numerous advantages, including, for example, the higher quality of the surface, the simplification of reworking on the ceiling pane and the lower effort involved in stripping. However, the handling of the lost shuttering panels in the prior art is disadvantageous, which is associated with a certain safety risk.

In the prior art, different types of frame constructions for remote uses, not for lost formwork, are also known.

EP 1 384 837 A1 discloses a frame construction that can be hung in brackets from uprights and brought into an inclined intermediate position during assembly.

FR 2 957 957 A1 discloses a frame structure with posts, a frame and formwork panels. During assembly, the frame is first folded on one side at the uprights 55 and then upwards.

EP 1 375 781 A1 likewise shows a frame construction consisting of an outer frame part and an inner frame part which can be pivoted with respect to the outer frame part.

Accordingly, the object of the present invention is to alleviate or eliminate at least individual disadvantages of the prior art. The aim of the invention is, in particular, to provide a method with which the use of lost ceiling tiles is made simple and safe.

This object is achieved by a method according to claim 1. Preferred embodiments are given in the dependent claims.

• Anordnen von zwei Deckenstützen auf einem Boden,
• Verbinden eines ersten Endbereichs eines Deckenschalungsrahmens mit den zwei Deckenstützen derart, dass der Deckenschalungsrahmen in einer vom ersten Endbereich in Richtung eines zweiten Endbereichs nach unten geneigten Zwischenstellung angeordnet ist,
• Verbinden einer verlorenen Deckenplatte mit dem in der Zwischenstellung angeordneten Deckenschalungsrahmen,
• Hochschwenken des zweiten Endbereichs des Deckenschalungsrahmens samt verlorener Deckenplatte,
• Abstützen des zweiten Endbereichs des hochgeschwenkten Deckenschalungsrahmens mit zumindest einer weiteren Deckenstütze und
• Gießen des Deckenelements samt verlorener Deckenplatte auf dem Deckenschalungsrahmen.

In the method according to the invention, at least the following steps are carried out:

• Arranging two slab props on a floor,
• Connecting a first end region of a ceiling formwork frame to the two ceiling supports in such a way that the ceiling formwork frame is arranged in an intermediate position inclined downward from the first end region in the direction of a second end region,
• Connection of a lost slab to the slab formwork frame in the intermediate position,
• Swiveling up the second end area of the slab formwork frame including the lost slab,
• Supporting the second end area of the pivoted-up ceiling formwork frame with at least one further ceiling support and
• Pouring the ceiling element including the lost ceiling panel on the ceiling formwork frame.

In this way, the casting of the ceiling element can advantageously be prepared from the ground. The lost ceiling panel is arranged on the ceiling formwork frame, while the ceiling formwork frame is arranged in the intermediate position inclined from the first in the direction of the second end region towards the floor. In the intermediate position, the ceiling formwork frame is easily accessible from the ground in order to attach the lost ceiling panel to the ceiling formwork frame. In the intermediate position, the ceiling formwork frame is preferably arranged at an angle of at least 10 degrees, in particular at least 20 degrees, preferably at least 30 degrees, to a horizontal plane through the connection points of the first end region of the ceiling formwork frame with the ceiling props. Only then is the second end area of the ceiling formwork frame, together with the permanent ceiling panel arranged on it, pivoted upwards from the ground level and finally supported with the at least one further ceiling support, so that the ceiling formwork frame with the permanent ceiling panel is arranged in the (especially horizontal) position of use. This brings the essential advantage with the fact that when building the ceiling formwork from the ground, a closed work surface is first created on the top of the lost ceiling slab, which workers only have to enter afterwards in order to carry out further work on the lost ceiling slab, for example to provide reinforcement or to lay cables. Accordingly, work safety can be increased significantly. In contrast to this, in the prior art, the lost ceiling panels had to be arranged on formwork supports that were already in a horizontal position of use. However, this presupposed that the workers had to go to the formwork girders in order to arrange the lost ceiling panels on the ceiling formwork elements from above. During this time, however, there were sometimes even large openings or gaps in the formwork structure, which could impair work safety. In addition, projections of the panels over the edge of the formwork structure often posed a risk to workers. The panels could also be damaged by the projections. In contrast, the present method enables a safe and simple production of ceiling elements with at least one lost ceiling panel, ie one remaining in the ceiling element. The ceiling element is manufactured by adding concrete to the lost ceiling slab. A ceiling element (or correspondingly a floor element) is thus obtained, which can advantageously have a finished underside. Any reworking can therefore be reduced. In addition, the formwork can be made easier to prepare for the next casting process. The cleaning of the formwork can also be simplified.

For the purposes of this disclosure, the location and direction information, such as "above", "below", "horizontal", "vertical", relate to a horizontal state of use of the ceiling formwork frame for pouring the ceiling element. Of course, the ceiling formwork frame can, however, also be arranged inclined to the horizontal in order to produce an inclined ceiling element.

A ... panel is preferably used as the lost ceiling panel. The lost ceiling panel is preferably made from a material from the group consisting of plaster of paris, wood, wood composite material, plastic, steel, aluminum and / or a combination thereof. The Lost ceiling panels can have reinforcements, such as glass fibers, or reinforcement.

In a preferred application, the lost ceiling plate has markings on the upper side (ie on the side facing away from the floor) which preferably illustrate a line plan for the ceiling element in order to allow the installation of lines, such as electrical lines or pipelines, on the lost before concreting To facilitate ceiling panel.

According to a preferred embodiment, the lost ceiling panel is inserted into a holder of the ceiling formwork frame for connection to the ceiling formwork frame. With this design, the lost ceiling panel can be connected to the bracket of the ceiling formwork frame in the intermediate position without tools. The holder preferably has a support surface for placing the lost ceiling plate on. The support surface preferably has a section each along two transverse and two longitudinal sides of a ceiling formwork frame that is rectangular in plan view. It is particularly preferred if the bearing surface extends continuously along the two transverse and the two longitudinal sides of the ceiling formwork frame. Accordingly, a circumferential support is preferably provided for the lost ceiling plate. In the state connected to the ceiling formwork frame, the lost ceiling panel advantageously does not protrude beyond the longitudinal and transverse sides of the ceiling formwork frame. Due to the lack of overhangs, the safety during shuttering and stripping and the quality of the cast ceiling element are increased.

In addition, the holder preferably has a holding web which protrudes upward from the support surface. The retaining web preferably has one section each along the two transverse and two longitudinal sides of the ceiling formwork frame. It is particularly preferred if the retaining web extends continuously along the two transverse and the two longitudinal sides of the ceiling formwork frame. The wall thickness of the lost ceiling panel corresponds essentially to the height (ie the vertical extent) of the retaining web, so that the top (ie the side facing the concrete) of the lost ceiling panel is essentially flush with the upper side of the retaining web. The lost ceiling panel is preferably arranged loosely in the holder of the ceiling formwork frame. Due to the dead weight of the lost ceiling panel, a secure arrangement on the ceiling formwork frame can be guaranteed.

In order to facilitate the construction of the ceiling formwork in preparation for pouring or concreting the ceiling element, it is advantageous if the ceiling formwork frame is held independently in the intermediate position, with the second end area of the ceiling formwork frame and the lost ceiling panel being spaced from the floor. This means that the slab formwork frame can be positioned in the intermediate position without manual support of the second end area (and without placing the second end area on the ground) before the ceiling formwork frame is pivoted upwards into the position of use via its second end area. For this purpose, the slab formwork frame can have support sections or support receptacles on opposite longitudinal sides in which corresponding pins or noses are received or held on the heads of the slab supports in the intermediate position of the slab formwork frame inclined to the horizontal.

In an alternative embodiment, especially in the case of low room heights, the second end region of the ceiling formwork frame can be placed on the floor in the intermediate position.

In order to swivel up the ceiling formwork frame including the lost ceiling panel from the ground, it is advantageous if the second end area of the ceiling formwork frame including the lost ceiling panel is pivoted up from the intermediate position with a mounting rod. The assembly rod can have an engaging element at a free end which can be brought into engagement with a transverse frame element at the second end region in order then to displace the ceiling formwork frame upwards with the aid of the assembly rod.

In order to ensure safety when working on the lost ceiling slab before pouring, an excavation protection is preferably provided between the ceiling props and the ceiling formwork frame, with which the ceiling formwork frame in the swiveled-up position of the ceiling formwork frame against lifting off Slab props is secured. A corresponding anti-lifting device can be provided between the further ceiling supports and the ceiling formwork frame. The excavation safety device preferably has a retaining lug on the ceiling support (or alternatively on the ceiling formwork frame) and a retaining flange on the ceiling formwork frame (or in the alternative design on the ceiling support), which are brought into engagement with one another when the ceiling formwork frame is pivoted up, so that a vertical relative movement is locked between the retaining lug and the retaining flange.

In order to absorb the load when the ceiling element is being poured, it is advantageous if the ceiling formwork frame has two longitudinal sides and two transverse sides, with at least one transverse rib extending substantially in the direction of the transverse sides being provided. Preferably, a plurality of transverse ribs or transverse girders that are spaced apart from one another in the longitudinal direction of the ceiling formwork frame, in particular that run parallel to one another, are provided. The ceiling formwork frame is preferably elongated in the longitudinal direction (i.e. in the direction of the longitudinal sides).

To produce large-area ceiling elements, in a preferred embodiment, at least two ceiling formwork frames, each with a lost ceiling panel, are arranged next to one another in the pivoted-up position before the ceiling element together with the lost ceiling panels is poured onto the ceiling formwork frame. Preferably, two adjacent longitudinal or transverse sides of two ceiling formwork frames can be supported on two common ceiling supports.

In a particularly preferred embodiment, an intermediate space between facing side surfaces of the lost ceiling panels is filled with a filling compound after the ceiling element has been poured. The space is in particular designed as a negative shape of adjacent retaining webs of the ceiling formwork frame. By filling the gap after concreting, an essentially flat underside of the ceiling element can be achieved. It is particularly advantageous that the reworking on the ceiling element can be done particularly easily and quickly. In the manufacture of ceiling elements with reusable Formwork, on the other hand, it is often necessary to grind off protruding concrete beads or concrete burr (ie excess concrete material) in the area of adjacent formwork panels in order to produce a flat underside. In contrast, with the method described above, the gap can be filled with filling compound, for example filler compound, with significantly less effort. If, during concreting, a concrete ridge or a concrete flag is created in the space between the lost ceiling panels, this can be hidden within the filling compound.

In a further preferred embodiment, a sealing tape is placed along adjacent edge areas on the tops of the lost ceiling panels prior to casting. The sealing tape makes it possible in particular to cover the gaps between the lost ceiling tiles due to tolerances and to prevent the lower ceiling surface from being soiled. Depending on the design, a gap can also be closed between the lost ceiling plate and the ceiling formwork frame. Swiveling the frame away can also be made easier.

The slab formwork frame preferably has an elevation along its longitudinal sides and / or transverse sides, i.e. an upward curvature. The elevation can be several millimeters to centimeters, for example. As a result, in the position of use the lost ceiling panel can be in an upwardly curved state, the panel preferably being arranged on bearing surfaces in the ceiling formwork frame for the lost ceiling panel. This enables the formation of a slight curvature in the cast or resulting ceiling, as a result of which statically induced subsidence in the finished ceiling can subsequently be compensated for in a simple manner without any action. This elevation enables a significant weight reduction in the dimensioning of the ceiling formwork frame with regard to the evenness of the finished ceiling element.

After the ceiling element of the ceiling formwork frame has hardened, the ceiling props or the at least one further ceiling prop can be removed or transferred to an inclined rest position. After that, the slab formwork frame in the Intermediate position can be arranged. The slab formwork frame can then be detached from the slab props remaining in the supporting position and removed.

Fig. 1 shows a ceiling formwork 1 for concreting a ceiling element 2 (see Fig. 12 , 14th ). The ceiling formwork 1 has two ceiling supports 3 for supporting a first (longitudinal) end region 4 of a ceiling formwork frame 5 and two further ceiling supports 6 for supporting a second end region 7 of the ceiling formwork frame 5. A lost ceiling plate 8 is arranged on the ceiling formwork frame 5, which thus remains in the ceiling formwork element 2 after concreting. Accordingly, the ceiling plate 8 is designed as permanent formwork.

In the exemplary embodiment shown, the ceiling formwork 1 has three further ceiling formwork frames 9, on which further permanent ceiling panels 10 are arranged. The other ceiling formwork frames together with other lost ceiling panels 10 are supported on additional ceiling supports 11. The further ceiling formwork frames 9 are preferably configured in accordance with the ceiling formwork frame 5 and the further lost ceiling panels 10 are configured in accordance with the lost ceiling panel 8. The ceiling supports 3, further ceiling supports 6 and additional ceiling supports 11 can also be of identical design.

The structure of the ceiling formwork 1 is based on the Figs. 2 to 5 emerged. In the first step, the two ceiling props 3 are placed on a floor 12 (cf. Fig. 1 ), which is formed, for example, by the floor below of a building to be erected using the ceiling formwork 1. Such ceiling props 3 are well known in the prior art. In the embodiment shown, each ceiling support 3 has an upper ceiling support part 13 and a lower ceiling support part 14, which are vertically adjustable relative to one another in order to adjust the height (ie the vertical extension) of the ceiling support 3 depending on the application. The ceiling prop 3 has a locking device 15 for locking the upper ceiling prop part 13 in different height positions relative to the lower ceiling prop part 14. The locking device 15 can have a bracket 16 which can be inserted through corresponding holding openings 17 of the upper ceiling support part 13 which are spaced apart from one another in the vertical direction. At the upper end area of the ceiling support 3, a head part 18 is also provided, which is set up for a detachable connection to the first end area 4 of the ceiling formwork frame 5. In addition, an anti-lifting device can be provided on the heads of the ceiling supports 3 on which the ceiling formwork frame 5 is supported, with which the ceiling formwork frame 5 is secured against lifting off the ceiling formwork frame 5 when the ceiling formwork frame 5 is pivoted up.

Like in particular from Fig. 2 and Fig. 6 As can be seen, the ceiling formwork frame 5 in the embodiment shown is rectangular in plan view with two opposite longitudinal sides 19 and two opposite transverse sides 20 formed. Longitudinal frame parts 21 are provided on the longitudinal sides 19 and transverse frame parts 22 are provided on the transverse sides 20. In addition, the ceiling formwork frame 5 has several transverse ribs 23 which extend parallel to the cross frame parts 22 on the transverse sides 20 of the ceiling formwork frame 5.

After the arrangement of the ceiling props 3 in their vertical support position on the floor 12, the first end region 4 of the ceiling formwork frame 5 is suspended in the head parts 18 of the ceiling props 3. In this case, the ceiling formwork frame 3 is arranged in an intermediate position that is inclined downwards from the first end region 4 to the second end region 7. Depending on the design, the ceiling formwork frame 5 can be held independently in the intermediate position.

In the next step, cf. Fig. 3 , the lost ceiling panel 8 is connected to the ceiling formwork frame 5 arranged in the intermediate position. For this purpose, the lost ceiling plate 8 is placed in a holder 25 of the ceiling formwork frame 5, which is shown in detail Fig. 6 , Fig. 10 emerges. The holder 25 has a support surface 26 for placing the lost ceiling panel 8 on, and a holding web 27 for framing the lost ceiling panel 8 on the longitudinal and / or transverse side.

In the next step, the ceiling formwork frame 5 together with the lost ceiling panel 8 with the aid of the assembly rod 24 in the horizontal position of use according to FIG Fig. 4 swung up. The second end area 7 of the ceiling formwork frame 5 is supported with the two further ceiling supports 6. For this purpose, the head parts 18 of the further slab props 6 are connected to the second end region 7 of the slab formwork frame 5.

In Fig. 5 A further intermediate position of the ceiling formwork frame 5 is shown, which is preferably assumed when at least two ceiling formwork frames 5 are positioned next to one another (as in Fig. 1 shown). In this embodiment, the second end region 7 of the ceiling formwork frame 5 is initially supported in the swiveled-up position only with the first of the two further ceiling supports 6 and is preferably secured with the aid of the assembly rod 24. Then the adjacent further ceiling formwork frame 9 is arranged in the swiveled-up position. Finally, the second of the further slab props 6 is connected to the free corner areas of the slab formwork frame 5 or the further slab formwork frame 9.

In this way, the slab formwork 1 is as in Fig. 1 shown constructed. In the position of use, the ceiling element 2 including the lost ceiling panel 8 (and, depending on the design, a number of additional ceiling panels 10) is finally cast. The ceiling element 2 therefore has a concrete layer 28 on the top, on the underside of which the lost ceiling slab 8 (and any other ceiling slabs 10, cf. Fig. 11 ) is arranged. In order to ensure a permanent bond between the lost ceiling slab 8 and the concrete layer 28, the ceiling slab 8 preferably has a material that bonds itself to the concrete of the concrete layer 8 in the liquid state. Alternatively, the ceiling plate 8 can have a roughened upper side or depressions or elevations, for example, noses, forming surface structures, by means of which the ceiling plate 8 is held with the concrete layer 28 by a form fit.

When concreting, an intermediate space 29 is formed between facing side surfaces 30 of the lost ceiling panels 8, 10. After the ceiling element 2 has been poured, the space 29 can be filled with a filling compound 31 (see Fig. Fig. 11 and Fig. 14 ). The advantage here is that a concrete ridge 32 in the joint area of adjacent ceiling formwork frames 5, 9 can be hidden within the filler compound 31, so that there is no need for time-consuming grinding of the concrete bead 32, as in the case of reusable formwork with several formwork panels abutting one another.

In the Figures 12-14 an alternative embodiment is shown, with only the differences to the embodiment of FIG Figs. 1 to 11 explained.

In this embodiment, before the ceiling element 2 is cast, at least one sealing tape 33 is arranged only along adjacent edge regions 34 on the upper sides 35 of the permanent ceiling panels 8, 10. The sealing tape 33 therefore bridges the gap 29.
