Description

Deckenschalungssvstem

The invention relates to a slab formwork system with a plurality of grate elements, each consisting of a plurality of mutually parallel longitudinal members and at least, a mounted on vertical supports or lay on, transverse to the longitudinal members extending cross member.

In the case of such slab formwork systems, a grate structure based on vertical supports, the outer contour of which corresponds at least substantially to the slab formwork to be created, is constructed in a first assembly Schmitt from grate elements, which consist in particular of longitudinal and transverse beams connected to one another. In a second assembly step is then applied to this rust structure from above either consisting of individual formwork panels surface formwork or even an array of hollow stones or cassettes, as they are often processed in ceiling structures in southern Europe.

A disadvantage of the known slab formwork systems is the fact that especially when using hollow stones or cassettes stripping of the generated ceiling can be done only after a substantially complete hardening of the concrete, so that the grate elements used including the associated vertical supports during the entire curing process without another up to fourteen days, must be left on site. Accordingly, during the curing process, it is not possible to use the ten grate elements or vertical supports otherwise, for example, to create another floor of a building to use, which increases the amount of material to be operated in an undesirable manner.

To avoid this disadvantage, it is known to use slab formwork systems, which are constructed of a plurality of individual, not interconnected transverse and longitudinal members, ie without the use of complete grate elements, in which case additional Schnellausschalprofile be used, which are supported on the bottom side and after the removal of said longitudinal and transverse beams can still be left on site, so as to continue to support a formwork, hollow stones or cassettes after a first hardening period. In such systems is a disadvantage that their structure and in particular the introduction of Schnellausschalprofile is associated with a certain risk, since the fitter must move in the activities mentioned in the plane that he just created, which requires that this level is still incomplete is, so there is a danger of falling.

An object of the invention is to provide a slab formwork system, which on the one hand allows the creation of slab formwork with low material costs and on the other hand ensures increased safety of the installer during installation.

This object is achieved in that at least two adjacent grate elements are mounted spaced apart such that between such mounted grate elements from above a Schnellausschalprofil can be introduced.

According to the invention is therefore intended to allow the use of quick Ausschalprofilen even when using grate elements. In this way, a shell level to be created from rust elements of the underlying level can be completely created, so that then the already completely created level can be safely entered by a fitter during the subsequent introduction of Schnellausschalprofile from above, since the created rust structure already sufficient Fall protection represents. Consequently, according to the invention, the installer enters the formwork level to be created for the first time when all the grate elements of the level to be created have already been mounted, which means that he is not exposed to any dangers when creating the grate structure. During the subsequent introduction of Schnellausschalprofile the created level - as mentioned - due to the already complete, usually seamless rust structure are entered safely. In this respect, it is achieved according to the invention that it is also possible with a comparatively high level of safety for the installer during dismantling to disassemble the grate elements used, including the vertical supports coupled therewith, at a relatively early point in time of the hardening process, since the quick-release profiles then supported on the bottom side still provide sufficient support of the formwork, the hollow stones or cassettes.

The use of quick-release profiles according to the invention thus makes the entire process of creating and dismantling a formwork both quicker, cheaper and safer. With regard to the cost aspect, it should be mentioned in particular that the grate elements used according to the invention, including the associated vertical supports, can already be dismantled in practice one or two days after the creation of a ceiling, so that considerable savings in terms of the otherwise usual service life of up to fourteen days of the total amount of material to be operated. It is preferred if the quick selvedge profile has a length corresponding to the longitudinal members of the grate elements, since such a quick selvedge profile can then be used without problems within the grid dimensions of the slab formwork system.

Furthermore, it is advantageous if the cross members of the grate elements protrude with their ends over the longitudinal members connected to them. In concrete terms, such a cross member protrudes perpendicularly to the outermost longitudinal member of a grate element above it, which means that the quick release profile according to the invention can be supported on this projecting section of the crossmember. Such a support on cross members requires advantageously that the Schnellausschalprofile can be easily inserted from above into a grate element structure without having to be supported from the beginning by means of vertical supports on the ground. Immediately after the introduction of Schnellausschalprofile they do not have to absorb relevant forces, so that a support on the cross members of the already mounted grate elements is completely sufficient. Only before the grate elements are then dismantled after creating a ceiling and after completion of a first curing period, the Schnellausschalprofile must be supported on the bottom side by means of vertical support, since after disassembly of the grate elements, of course, no support can be given by the cross member.

It is particularly preferred if the quick shuttering profile can be supported at its two end regions on the ends of cross members of adjacent grate elements. This then implies that a quick cutout profile ultimately rests on a total of four mutually facing end sections of the four cross members of two adjacent grate elements. The quick shuttering profile can each have at its two ends a coupling section which engages over cross members of grate elements or engages between cross members of grate elements such that the relative position between the quick shuttering profile and cross members is fixed in the longitudinal direction of the quick shuttering profile and / or perpendicular thereto. In this way it is ensured without the use of any separate parts alone by placing a Schnellausschalprofils on the corresponding cross member sections, that the desired relative position between Schnellausschalprofil and grate elements does not change unintentionally. It is particularly preferred in this case if the coupling section engages between cross members of adjacent grate elements. Such an intervention ensures, in particular, that the relative position between the quick shuttering profile and the cross members is fixed perpendicular to the longitudinal direction of the quick shuttering profile.

It is particularly advantageous if the cross members are designed such that they can be released by a linear downward movement or a pivoting away from the coupling portion. In this case, after a first hardening period of, for example, one to two days, the quick-release profiles present in the formwork can be supported on the bottom side by means of vertical supports, whereupon the vertical supports coupled to the grate elements can be dismantled and the grate elements thus freed can simply be lowered or swiveled linearly , It thus results in an extremely simple disassembly of the grate elements at the end of the first curing period, which also represents the beginning of the second curing period, then take over the supporting at this time bottom side quick release according to the invention a supporting function. The upper side of a mounted quick-release profile is preferably arranged above the plane in which the upper sides of the longitudinal members extend. This means that the tops of the quick release profiles ultimately come to lie between individual formwork panels or between individual hollow stones or cassettes and form a direct contact surface for the introduced concrete. It is desirable that the distance between the top of a mounted quick release profile and the tops of the side rails corresponds to the thickness of formwork panels mountable on the side rails to provide a flush, stepless transition between the tops of the quick release rails and the formwork panels.

In order to provide support for the quick release profiles prior to the start of the second curing period, their undersides are provided with at least one or two connecting elements for connection to an upper end of vertical supports. These connecting elements are preferably provided at a distance from the coupling sections, which serve for coupling the quick shuttering profiles with the cross members of the grate elements.

It is particularly advantageous if longitudinally aligned cross members of two adjacent grate elements can be mounted on a head of a vertical support at different distances from one another. In this case, a first distance of the cross member may be selected so that the distance of the adjacent outer side member of the adjacent grate elements corresponds to the normal grid spacing of two side members of a grate element. A second, likewise realizable distance is made up of the sum of the mentioned measure and the width of the upper side of a quick shuttering profile. In the advantageous use of the second distance it is ensured that between two A shuttering board of the same size can be fitted flush in parallel with each other, in which it can also be used for a slab formwork area using the grate elements without the use of quick shuttering profiles. When using the first distance, however, formwork panels of a different size must be used for shuttering surfaces which are located between mutually parallel, adjacent quick shutter profiles, so that here then shuttering panels must be provided in at least two different sizes.

Further preferred embodiments of the invention are described in the subclaims.

The invention will now be described by way of example with reference to the drawings; in these show:

Fig. 4 is a view according to FIG. 3 obliquely from above, and Fig. 5 is a side view of a vertical support with according to FIGS.

3 and 4 supported thereon cross member to which in turn a Schnellausschalprofil is supported.

Fig. 1 shows a grate structure, which consists of a plurality of grate elements 2, 2 ', 2 "and 2'". Each of the grate elements 2, 2 ', 2 ", 2'" consists of a total of five longitudinal support 4, which are connected by means of cross members 6 firmly together. The longitudinal members 4 of each grate element 2, .2 ', 2 ", 2'" extend perpendicular to the cross members 6 and are substantially equidistant from each other. The upper sides of the cross member 6 are respectively coupled at the two opposite ends of the longitudinal members 4 with the underside, wherein the cross member 6 extend beyond the respective outermost longitudinal members 4 of each grate element 2, 2 ', 2 ", 2'" something out to to form such a support surface for Schnellausschal- profiles 8, 8 ', 8 ".

The cross member 6 are supported on the bottom side by means of vertical supports 10.

Between the adjacent grate elements 2 ', 2 "a Schnellausschalprofil 8' is introduced, which extends parallel to the respective outermost, mutually facing longitudinal members 4 of the grate elements 2 ', 2". This Schnellausschalprofϊl 8 'is supported with two provided at its front end portions coupling portions 14 (Fig. 2) on a total of all four cross members 6 of the grate elements 2', 2 ".

Another quick shuttering profile 8 "is arranged, for example, between the grate element 2" and the grate element 2 '", which shows that a quick shuttering profile 8" can also be inserted between such grate elements 2 ", 2'". can be brought, the side members 4 extend perpendicular to each other.

According to FIG. 1, other quick-release profiles 8 are also used, but will not be discussed in more detail here.

1 is supported on the bottom side by means of separate vertical supports 12. Such support of quick shuttering profiles 8 must be made before vertical supports 10 and grate elements 2, 2 ', 2 ", 2'" are dismounted after a first curing period. During the first curing period, in which the grate elements 2, 2 ', 2 ", 2'" are still mounted, those vertical supports 12 which are suitable for supporting Schnellausschalprofϊlen 8, 8 ', 8 ", not yet required.

The vertical supports 10, the vertical supports 12, the grate elements 2, 2 ', 2 ", 2'" and the Schnellausschalprofile 8, 8 ', 8 "are each formed identical to each other.

FIG. 2 shows a three-dimensional view of a quick shuttering profile 8, which in each case has a coupling section 14 at its two end-side end regions, which extends substantially vertically downwards starting from the end faces of the quick shuttering profile 8.

The two coupling portions 14 each have an outer abutment surface 16, wherein the inner sides of the abutment surfaces 16 are spaced apart such that the two cross members 6 of a grate element 2 find space between them such that a displacement of the Schnellausschalprofils 8 in its longitudinal direction relative to the cross members 6 is not possible. Furthermore, the coupling sections 14 each have two engaging tabs 18, which can engage between adjacent transverse beams 6 of two adjacent grate elements 2, so as to prevent a shifting of the quick shuttering profile 8 perpendicular to its longitudinal direction and parallel to the shuttering plane to be created.

The described design of the two coupling portions 14, it is thus possible to introduce a quick Ausschalprofil 8 from above between two adjacent grate elements 2 and support on the cross members 6 of these grate elements 2 such that an undesirable relative movement between the grate elements 2 and the Schnellausschalprofil 8 is avoided. The fact that said coupling can be accomplished by an exclusively linear movement of Schnellausschalprofils 8 vertically downwards, it is possible in an analogous way to solve rust elements 2 by a linear movement of the same downward from a Schnellausschalprofil 8, after the vertical supports 10 of the grate elements 2 were removed. Likewise, of course, a pivoting of the grate elements 2 about a parallel to the cross members 6 extending axis is possible.

On its underside, the quick shuttering profile 8 has two connecting elements 20, via which the quick shuttering profile 8 can be supported on the bottom side by means of vertical supports 12. The connecting elements 20 are designed such that a vertical support 12 can be detachably connected to the quick-cut profile 8.

FIGS. 3 to 5 show the manner in which a quick shuttering profile 8 'can be placed on two cross members 6 of two adjacent grate elements 2', 2 "according to FIG. The underside of the coupling portion 14 rests on the upper sides of the two mutually parallel cross member 6, wherein the stop surface 16 abuts the end portions of the side walls of the cross member 6, so that a displacement of the Schnellausschalprofils 8 'in the direction of arrow A is impossible (see FIG 4 and 5).

The engaging tabs 18 (Figure 5) engage in the space between the two cross members 6 so that the quick release profile 8 'can not be displaced in the direction of the double arrow B (Figure 4).

In particular, from Fig. 3 it can be seen that the top of the Schnellausschalprofils 8 'is disposed in a higher plane than the tops of the side members 4, which is associated with the advantages already described.

The quick shuttering profile 8 'is supported on the bottom side by a vertical support 12 (FIG. 3), which is shown only in sections.

The way in which the cross member 6 are supported on the vertical support 10 (see Fig. 5) is not the subject of this application and is therefore not explained in detail here.
