Description

The invention relates to a ceiling formwork system with at least one side protection for a ceiling formwork, the ceiling formwork comprising at least one formwork element with a frame. The invention also relates to a method for erecting such a ceiling formwork system.

It is known to use ceiling formwork made from formwork elements to produce concrete ceilings. In particular, frame panel formwork elements are used, which at least partially form a mold for filling in liquid concrete. In order to produce a concrete ceiling, a ceiling formwork supported by ceiling props is erected first. A desired room height can be achieved by positioning the ceiling formwork at a certain height. The standard room height in Germany, for example, is at least 2.40 meters for single-family, two-family and terraced houses, with commercial real estate having a much higher room height can have. The filling of the liquid concrete on the ceiling formwork is done by workers who have to go to the ceiling formwork. In order to protect these workers from a life-threatening fall from the slab formwork while pouring the concrete, a side protection is mounted on the slab formwork before pouring the concrete. For this purpose, side railing holders are attached to the side of the slab formwork, in which side railings are fastened. The slab formwork is secured laterally by the side railings and workers are prevented from falling off the slab formwork. As a rule, the installation of the side protection is carried out by workers who have to walk through the slab formwork.

In EP 2 757 212 A1 describes a device for mounting a safety railing on a formwork for floor slabs, which comprises at least two of the following elements: means for pivoting a first end of an extension element running predominantly in the longitudinal direction below a formwork panel or below the edges of two laterally adjacent formwork panels, means for locking the a second end of the predominantly longitudinal extension member at an edge of the form panel, the second end having means for mounting a support and attachment portion of a safety rail.

The problem is that there is an increased risk of workers falling from the slab formwork during the installation of the side protection.

The present invention is therefore based on the object of designing and developing the known side protection in such a way that it enables safe assembly.

According to the invention, this object is achieved by a ceiling formwork system having the features of patent claim 1 and by a method for erecting such a side protection according to patent claim 11 .

The subclaims indicate appropriate developments.

The object according to the invention is thus achieved by a ceiling formwork system comprising a ceiling formwork with at least one formwork element with a frame, at least one side protection mounted on the ceiling formwork in an end position, and a suspension rail. The ceiling formwork comprises at least one formwork element with a frame. The side protection has a railing. Furthermore, the side protection has a pivoting frame to which the railing is connected and which is indirectly connected to the frame of a formwork element from the underside of the ceiling formwork. The pivoting frame can be pivoted out of an assembly position about an axis of rotation A into the end position, in which end position the railing secures the ceiling formwork laterally in the area of the free edge of the at least one formwork element. The hanging bar has a horizontal alignment or orientation. According to the invention, the pivoting frame is first indirectly mounted on the frame of a formwork element from a safe ground. The pivoting frame, together with the railing attached to the pivoting frame, is then also pivoted from a safe ground out of an assembly position into an end position in such a way that the ceiling formwork is laterally secured by the railing. The lateral protection always protects the free edge of the slab formwork. In the assembly position, the swing frame is connected to the frame of the Formwork element connected indirectly, but the swing frame is not yet swung open. In the end position, the railing protrudes laterally over the slab formwork. In this case, upwards beyond the ceiling formwork means that the railing extends from the ceiling formwork, which is arranged parallel to the floor, in a direction away from the floor.

Workers therefore do not have to inspect the unsecured slab formwork to attach the side protection. When inspecting the ceiling formwork for pouring the liquid concrete onto the formwork elements, the ceiling formwork is already secured at the side. A life-threatening fall from the ceiling formwork during a first inspection of the ceiling formwork is thus effectively prevented according to the invention. A safe installation of the side protection according to the invention is guaranteed.

According to the invention, the pivoting frame is indirectly pivotably connected to the frame, namely via the suspension bar.

In this case, the suspension rail is connected to the frame and the pivoting frame is connected to the suspension rail so that it can pivot about an axis of rotation A.

The pivoting frame may include a pivoting base frame and a pivoting flap. The pivoting flap is pivotably connected about an axis of rotation B to the pivoting base frame. The swivel base frame can have two longitudinal beams. The longitudinal beams can be connected to one another by a plurality of cross beams. The cross section of the longitudinal beams, like the cross section of the cross beams, can have different geometric shapes. would be conceivable for example a cylindrical or any polyhedral shape. However, the longitudinal beams are preferably designed with a rectangular cross section and the cross beams with a square cross section. Furthermore, the longitudinal beams, like the cross beams, can be made of solid solid material. However, the longitudinal beams and the cross beams are preferably designed as hollow profiles. This has a weight advantage compared to massive production. As an alternative or in addition to this, the longitudinal beams can be connected to one another by transverse connectors. The cross-connectors are designed as flat plates. Longitudinal members, cross members and/or transverse connectors can be made of plastic or wood. However, these are preferably made of metal, for example aluminum or steel. The crossbeams and the transverse connectors can be firmly connected to the longitudinal beams, for example glued, latched, screwed or welded.

The longitudinal members can be formed in two parts, namely having a first longitudinal member part and a second longitudinal member part angled to the first longitudinal member part. The first longitudinal member part and the second longitudinal member part can be firmly connected to one another. A connection by means of a connecting element would be conceivable. It is also conceivable for the first longitudinal member part and the second longitudinal member part to be glued, latched, screwed, positively or non-positively connected to one another. However, the first longitudinal member part and the second longitudinal member part are preferably welded to one another. The angle between the first side member part and the second side member part can be 90 degrees to almost 180 degrees. However, the angle between the first longitudinal member part and the second longitudinal member part is preferably approximately 90 degrees.

A pin can protrude from each of the two first longitudinal beam parts in the region of their free ends. In principle, the pin can only be arranged on those side surfaces of the respective first longitudinal member that make it possible for the longitudinal axis of the pin arranged on one of the two first longitudinal members and the longitudinal axis of the pin arranged on the other of the two first longitudinal members to be in the common axis of rotation A lie. The side surface of the respective longitudinal support part, which is opposite the side surface having the pin, can also have a pin. Of particular importance here is that the longitudinal axes of all the pins necessarily lie in the common axis of rotation A. However, each of the two first longitudinal member parts preferably has a passage through which a pin extends. The pin extends on both sides away from the respective first longitudinal member part or projects out of the respective first longitudinal member part on both sides. Again, the longitudinal axis of the pin extending through the passage of one of the two first longitudinal member parts and the longitudinal axis of the pin extending through the passage of the other of the two first longitudinal member parts must lie in the common axis of rotation A.

In a further embodiment, the axis of rotation A can run at a distance from the two first longitudinal member parts. In this embodiment, spacer pieces are formed at the ends of the two first longitudinal beam parts, which extend essentially at right angles to the first longitudinal beam parts. The pins, which then lie in the axis of rotation A, are formed in the free end area of the spacer support pieces.

Are spacer pieces provided on the first longitudinal member parts, so these are also formed between the first longitudinal member parts and the second longitudinal member parts.

If swing frames are provided with and without spacer pieces, these swing frames can be arranged crosswise. This means that swing frames with spacer pieces can run below swing frames without spacer pieces. It is thus possible to equip the long and short sides of a slab formwork with side protection at the same time using the swing frame with and without spacer support pieces.

The identical suspension rails can be used for both versions of swing frames with and without spacers. The pivoting flap can have two side parts. The side parts can be designed as elongated plates which have a profile on their side areas. The side parts can preferably have a step on one of their longitudinal sides in the edge area for contact with the formwork element. The side parts can be made of plastic, metal or wood. However, the side parts are preferably made of metal. The side parts can be connected to one another at least via a further cross member. The cross section of the at least one further cross member can have different geometric shapes. For example, a rectangular, a cylindrical or any polyhedral shape would be conceivable. However, the cross section of the at least one further cross member is preferably designed as a square. The at least one further cross member can be firmly connected to the side parts, for example glued, screwed or welded.

A coupling element can be arranged on the further cross member. The coupling element can be permanently connected to the at least one further cross member, for example glued, screwed or welded. A securing element is articulated pivotably about an axis of rotation C on the coupling element. The securing element can have at least one lug for reaching behind one of the several cross members. The securing element preferably comprises two side plates of identical design, each of which has a nose and is connected to one another by a connecting plate. The coupling element is arranged between the two side plates of the securing element and is pivotably mounted via a further pin which extends through the side plates of the securing element and the coupling element. To prevent unintentional loosening of the rear grip on one of the several cross members, an elastic means can be provided between the securing element and the coupling element to generate a restoring force. The elastic means can, for example, be a spring or a rubber band.

The suspension bar can be designed as a carrier. The cross-section of the carrier can have different geometric shapes. For example, a rectangular, a cylindrical or any polyhedral shape would be conceivable. However, the cross section of the carrier is preferably designed as a square.

At least one hanging strap, in particular two pairs of hanging straps, can be arranged on the carrier. The suspension brackets are designed as plates that are essentially S-shaped. Each of the suspension brackets can have a first recess for receiving the pin at its end spaced apart from the carrier exhibit. The recess for receiving the pin can be shaped as a curved finger. In addition, the suspension lugs can each form a further second recess with the carrier for reaching behind a projection of the frame. The carrier and/or the suspension brackets can be made of wood, plastic or metal, for example aluminum or steel. The suspension brackets can be permanently connected to the carrier, for example glued, screwed or welded. The two first longitudinal member parts can each be positioned between one of the pairs of suspension brackets. In this case, a hanging bracket is arranged on each side of the respective first longitudinal member part. The pin extending away from the respective first longitudinal member part or the spacer pieces on both sides can be pivotably mounted in the recesses of the pair of hanging straps and can thus come to rest on both sides in a respective recess of a hanging strap.

As an alternative or in addition to the hanging straps, a securing flap can be arranged on the carrier. The safety flap can have a stop element. The stop element can be designed as an essentially crescent-shaped plate and can be made of wood, plastic or metal, for example aluminum or steel. Furthermore, the stop element can be firmly connected to the carrier, for example glued, screwed or welded. Like the suspension brackets, the stop element can form a further recess with the carrier for reaching behind a projection of the frame. Furthermore, the stop element can have a taper for engaging in a breakthrough opening of the frame. The taper can be wedge-shaped. The safety flap can also have a safety lever. The safety lever can be swiveled with the carrier related. For this purpose, the safety lever can have a further passage and a further pin can be provided on the carrier. The further pin arranged on the carrier can extend through the further passage of the safety lever. A detachment of the safety lever from the additional pin can be prevented by a cotter pin inserted into the additional pin.

The railing can have two longitudinal struts. The longitudinal struts can be connected to one another by several transverse struts. The longitudinal struts and/or the transverse struts can be made of wood, plastic or metal and can be firmly connected to one another, for example glued, screwed or welded. The longitudinal struts and/or the transverse struts can be made solid or designed as a hollow profile. A grid is formed by connecting the longitudinal struts to the transverse struts. The railing can be firmly connected to the second longitudinal support part, for example a respective longitudinal strut of the railing can be glued, screwed or welded to a respective second longitudinal support part. However, the railing is preferably plugged into the pivoting frame. For this purpose, the second longitudinal beam parts of the pivoting frame are designed as hollow profiles and the railing is inserted with one of its longitudinal struts in each case in one of the hollow profiles. For this purpose, the longitudinal struts must necessarily have a smaller outside diameter than the inside diameter of the second longitudinal beam parts designed as a hollow profile. The respective longitudinal strut can be positively and/or non-positively fixed in the respective hollow profile.

In the ceiling formwork system according to the invention, the at least one side protection is mounted on the ceiling formwork. The ceiling formwork includes at least one shell element. The at least one formwork element has a frame. The at least one side protection is mounted indirectly on the frame of this formwork element. If the floor formwork comprises a plurality of formwork elements, the one side protection can preferably be mounted on the frame of some of these formwork elements.

When the pivoting frame is fully pivoted into the end position, the first longitudinal beam parts are aligned essentially parallel to the formwork elements. In order to secure the pivoting frame on the formwork element in this position, the pivoting flap is pivoted completely in relation to the pivoting frame about the axis of rotation B in the direction of the pivoting frame. The step formed in each of the side parts of the pivoting flap comes to rest on the upper side of the formwork element, as a result of which the pivoting frame is kept supported on the formwork element. At the same time, the lug formed on each of the side plates of the securing element engages behind the closest of the plurality of cross members and latches thereto, thereby effectively preventing the step formed in each side part of the pivoting flap from slipping off the upper side of the formwork element. The side protection is thus firmly secured to the slab formwork and mounted in a fixed position.

In order to release the side protection from the slab formwork, first the rear grip of the lug formed on each of the side panels must be released from the nearest of the several crossbeams and then the pivoting flap must be pivoted away from the pivoting frame about the axis of rotation B, whereby the in each of the side parts the steps formed in the pivoting flap no longer rest on the upper side of the formwork element. The loosening of the rear grip However, the nose of the nearest of the several crossbeams can only be executed from the underside of the ceiling formwork. Therefore, the side protection cannot be detached from the floor formwork by incorrect operation by the people working on the floor formwork.

The object is further achieved by a method according to claim 11.

The method includes a step of indirectly connecting the swivel frame to the frame. Furthermore, the method has a work step of connecting the railing to the swivel frame. Furthermore, the method has a work step of pivoting the pivoting frame out of a mounting position about an axis of rotation A into an end position. Here, the swing frame is pivoted in such a way that the railing secures the ceiling formwork laterally.

Lateral protection means protection of the free edge of the slab formwork. In the end position, the railing projects upwards over the slab formwork. In this case, upwards beyond the ceiling formwork means that the railing extends from the ceiling formwork arranged parallel to the floor in a direction away from the floor.

To extend an existing ceiling formwork supported by ceiling props, individual formwork elements are each hooked into a guide bracket of a ceiling prop at two corners of their frame and then swiveled open from the safe ground.

In a step of connecting the swing frame to the frame, which is not according to the invention the swivel frame can be firmly connected to the frame, e.g. by gluing, screwing or welding. This can be done, for example, before pivoting open, when the respective formwork element to be pivoted is still on the ground. It should be noted here that the swing frame must be swung open together with the formwork element in the work step of swinging the swing frame open. With such a pivoting in one step, the weight of the formwork element and the pivoting frame must be pivoted at once.

According to the invention, the pivoting frame is connected indirectly to the frame in the step of connecting the pivoting frame, as a result of which the pivoting frame is articulated pivotably on the frame via the suspension bar, the axis of rotation A.

This connection can take place before or after the formwork element is pivoted open. The formwork element is first swiveled out alone and then the swivel frame. Pivoting open the formwork element and the pivoting frame separately from one another in the course of the work has the advantage that the weight of the formwork element and the pivoting frame do not have to be pivoted open at the same time. Pivoting open the formwork element together with the pivoting frame in one step is of course also conceivable with this variant.

Alternatively, the formwork element can be pivoted open in a first step without it being already connected to the pivoting frame. If the formwork element is positioned as a slab formwork element, then in a subsequent work step the suspension bar is connected to the frame of the pivoting element. After that, the swivel frame is connected to the suspension rail, ie it is hung in the first recesses via the pins. Alternatively, the suspension strip can also be mounted on the frame of the formwork element before the formwork element is pivoted open if the formwork element is still on the ground. With this variant, the formwork element and swing frame are swung open separately.

When securing the edge of a slab formwork, the hook-in rail is attached to the underside of any formwork element with side protection. The swing frame with the railing (the swing frame with railing here means the side protection, which is made up of first and second longitudinal beam parts, the railing and safety elements) is hooked into the suspension rail and the railing is accessible by swiveling the swing frame from below in front of the pivoting the free edge of the ceiling formwork in such a way that the railing protrudes beyond the formwork element to such an extent that there is safe occupational safety for people working on the ceiling formwork.

In a particular embodiment, the pivoting frame is articulated in the area of a formwork element via the suspension rail, which is fastened to a formwork element that is spaced apart from the edge formwork element by a further formwork element.

If a transverse side of a formwork element is to be secured by side protection, the pivoting frame can be articulated on the underside of a formwork element via the suspension bar, which is fastened to a formwork element directly following an edge formwork element.

As a result, the side protection can be mounted in an unchanged design either on the longitudinal or on the transverse side of a formwork element. whereby the free edge of the ceiling formwork can be secured on the long side of the formwork elements or on the short side of the formwork elements. If the swing frames intersect on the underside of formwork elements, while at the same time securing a slab edge, in a corner of the long and short side, spacer supports must be provided on one swing frame in such a way that it is possible for a swing frame to overlap a swing frame directly above it can reach under or on the underlying swing frame recesses must be provided at the points where two superimposed swing frames meet in the fully swung open state.

Further features and advantages of the invention result from the following description of several exemplary embodiments of the invention, from the patent claims and from the figures in the drawing.

The features shown in the drawing are presented in such a way that the configurations of the ceiling formwork system according to the invention can be made clearly visible.

1 shows a slab formwork system 100 supported by slab supports 1. The slab formwork system 100 comprises, in addition to a slab formwork 2, several elements of a side protection 3. The slab formwork 2 comprises several formwork elements 4. Two side protections 3 each are mounted on some of the several formwork elements 4.

The formwork elements 4 are designed in the form of frame panel formwork elements. The formwork elements 4 have a frame 5 and a formwork skin 6 . The formwork elements 4 are aligned with their formwork skin 6 facing upwards and joined to one another laterally. The formwork elements 4 have a longitudinal side and a transverse side. Accordingly, the frame 5 has two longitudinal frame parts 7 extending parallel to one another and two transverse frame parts 8 extending parallel to one another. The longitudinal frame parts 7 and the transverse frame parts 8 are aligned perpendicular to one another. The longitudinal frame parts 7 are twice as long as the transverse frame parts 8 . The longitudinal frame parts 7 extend on the longitudinal side of the formwork element 4. The transverse frame parts 8 extend on the transverse side of the formwork element 4.

The side protection 3 has a pivoting frame 10 , a railing 11 and a hanging rail 9 . The suspension bar 9 is arranged below the ceiling formwork 2, is covered by the formlining 6 and is in 1 indicated by a black bar (suspension bar 9). The railing 11 is connected to the swing frame 10 .

Are side protections 3 provided on the side of the transverse side of the formwork elements 4 arranged in the edge area of the ceiling formwork 2 (in 1 not shown), then the suspension rail 9 is mounted on the transverse frame part 8 of the second formwork element 4 that faces the transverse side to be protected—seen from the transverse side of the formwork element 4 to be protected.

After mounting the suspension rail 9 on the frame 5 of the formwork element 4 , the pivoting frame 10 is suspended from the ground in the suspension rail 9 and is pivoted there relative to the suspension rail 9 about an axis of rotation A. Directly after being hung in, the pivoting frame 10 is initially positioned in an assembly position. In the assembly position, the pivoting frame 10 is hooked into the suspension bar 9, but not pivoted open. From this assembly position, the pivoting frame 10 is then pivoted about an axis of rotation A into an end position. In the end position, the side protection 3 secures the slab formwork 2 laterally by the railing 11 . The side protection 3 protrudes upwards with its railing 11 in the end position over the ceiling formwork 2 .

A pin 20 is arranged in the through hole 13 and extends through the respective first longitudinal member 17 and protrudes from the respective first longitudinal member 17 on both sides beyond the side surfaces. The longitudinal axis of the pin 20 extending through the passage of one of the two first longitudinal member parts 17 and the longitudinal axis of the pin 20 extending through the passage of the other of the two first longitudinal member parts 17 lie in the common axis of rotation A. The second longitudinal member parts 18 are connected by a transverse connector 21 connected to each other. The cross connector 21 is designed as a round rod/tube.

In another in the figures 19 and 20 shown embodiment, the pin or pins 20 are not formed or arranged in the longitudinal support parts 17, but rather in the end regions of spacer support pieces, which are directed upwards at right angles, in the direction of extension of the second longitudinal support 18, and are rigidly attached to the ends of the longitudinal support parts 17. In this embodiment, the spacer pieces are also provided in the area between the longitudinal beam parts 17 and the longitudinal beam parts 18 . In the 2 embodiment shown and in FIG 19 Embodiment shown can be mounted overlapping on the underside of formwork elements 4, without each other collide. If these two embodiments are combined, the side protection can also be attached in corner areas of adjacent transverse and longitudinal sides of formwork elements 4 and side protection around the entire ceiling formwork 2 (completely) is also possible.

In the end region of the second longitudinal member 18, the pivoting base frame 14 is pivotably connected to the pivoting flap 15 about an axis of rotation B. The pivoting flap 15 has two side parts 22 which are connected to one another via two further crossbeams 23 . The side parts 22 are designed as flat plates which have a profile in one side area. The profiling is designed as a step 24 to rest on the upper side of the formwork element 4 ( 1 ) educated. One of the further crossbeams 23 connects the side parts 22 in the end area of the pivoting flap 15. This further crossbeam 23 has a coupling element 25 in its middle area. A securing element 26 is pivoted about an axis of rotation C on the coupling element 25 . The securing element 26 comprises two side plates 27 of identical design, each of which has a lug 28 and is secured by an in 2 connecting plate not shown are connected to each other. The coupling element 25 is arranged between the two side plates 27 of the securing element 26 and is pivotably mounted via a further pin 30 which extends through the side plates 27 of the securing element 26 and the coupling element 25 .

3 shows the suspension bar 9 in a perspective view. The suspension rail 9 has a carrier 31, in the end regions of which a pair of suspension straps 32 is arranged and in the middle region of which a securing flap 33 is arranged. The carrier 31 is designed as a hollow profile and has a square cross section. the Suspension brackets 32 are formed as flat, essentially S-shaped plates and have first recesses 34 on their end facing away from the carrier 31 for receiving a respective one of the pins 20 ( 2 ) on. Each of the suspension brackets 32 forms a further second recess 35 with the carrier 31 for reaching behind a projection of the frame 5 ( 1 ). The securing flap 33 has a stop element 37 and a securing lever 38, which is pivotably connected to the carrier 31, for fixing the hanging strip 9 on the frame 5 ( 1 ) on. The stop element 37 is designed as a flat, essentially crescent-shaped plate. The stop element 37 forms with the carrier 31, just like the suspension brackets 32 with the carrier 31, a further recess 35 for reaching behind the projection of the frame 5 ( 1 ). At one end, the stop element 37 has a wedge-shaped taper 39 for engaging in a breakthrough opening 40 of the frame 5 . The safety lever 38 is pivotally connected to the bracket 31 . For this purpose, the securing lever 38 has a further passage 41 and the carrier 31 has a further pin 42 . The additional pin 42 arranged on the carrier 31 extends through the additional passage 41 of the safety lever 38 .
