Description

Frame formwork systems for the formation of corners and T-junctions using frame scarf elements with center-aligned anchor holes

The invention relates to frame formwork systems and associated frame formwork arrangements for the production of corners and T intersections of concrete walls by means of a frame panel formwork.

Frame corner systems are known in the art.

Formwork is used in particular for the manufacture of concrete walls. The formwork limits a space in which the concrete wall is to be built. This room is filled up with liquid concrete. After the concrete has hardened, the formwork is removed.

With frame panel formwork, the concrete structures to be erected can be made particularly flexible. A frame panel formwork is formed by a plurality of individual, reusable Bauelemententen, which are assembled depending on the particular desired concrete structure on the site. The most important components of a frame panel formwork are rectangular frame formwork elements, supplemented by frame formwork corner elements. Rectangular frame scarf elements are relatively light, well stackable, and can be used in any orientation standing and lying.

The individual components of a frame panel formwork usually have a facing the liquid concrete facing, and on the back of the device runs a (usually encircling) frame, which mechanically stabilizes the device. Neighboring components are connected by means of Spannschiössem, the turnbuckles attack each of the frame.

In addition to the frame panel formwork, beam formwork and steel formwork are also known. Although these can be made very robust mechanically, they are not as flexible as frame panel formworks.

The liquid concrete trapped between opposing scarf elements exerts forces on the scarf skins due to gravity, which try to force the scarf elements apart. These spreading forces are greatest in the lower formwork area. In order to prevent the formwork from being spread apart, opposite formwork elements are connected to one another by so-called tie rods. The anchor rods protrude through the formwork skins and through the concrete structure to be created; with the anchor rods anchor plates, which abut respectively on the back of the shell elements, braced against each other. After completion of the concrete structure, the anchor rods and anchor plates are removed again.

In a known frame panel formwork series, the anchor holes, through which the tie rods protrude, pass through the peripheral frame of the rectangular frame formwork elements (so-called edge anchorage). The anchor plates are supported on the frame. An anchor plate engages behind not only the frame of the frame scarf element through which the anchor rod extends, but also the frame of an adjacent Panel formwork element. In this adjacent frame scarf element, an anchor hole located below the anchor plate is not used; for the attachment of another anchor rod would be too little space.

Overall, only a part (typically half) of the anchor holes are actually used for anchor rods in these known frame scarf elements. The remaining part of the anchor holes, which would come in other orientations of the frame scarf elements used, must be closed during construction of the formwork with plugs to prevent leakage of liquid concrete.

This placement of plugs represents a considerable amount of work and thus a large cost factor in the manufacture of concrete walls. Faulty plugs hinder the setting of anchor rods and may require correction work; Missing plugs result in leakage of liquid concrete and blockage of anchor holes with hardened concrete.

A similar problem as with the incorrect placement of plugs also occurs during the pre-assembly of nut elements for unilateral anchor elements in the so-called "one-sided anchorage", also here, if necessary, correction work is necessary.

Another well-known frame formwork corner system is based essentially on a comparable edge anchorage. This system for forming a skewed, obtuse corner of a concrete wall has an inner corner element and an outer corner element and two rectangular frame shell elements which adjoin the legs of the Inneneckelements (inner leg) on. The Inneneckelement is anchored exclusively on the lateral edge of the inner leg and across to the respective adjacent Rahmenschaielement. The outer corner element has in each leg (outer leg) an anchor grid, which is used for anchoring the Inneneckelements, as well as a Edge anchor anchoring the outer edge of the opposite rectangular Rahmenschaielements.

When using this known Rahmenschalungs corner system must - especially in the outer corner element, in the corner system belonging frame scarf elements and in the frame scarf elements that are directly adjacent to the corner system - plug are placed in unneeded anchor holes, and incorrect assembly correction work is needed. The same applies to the pre-assembly of nut elements.

Object of the invention

It is therefore the object of the present invention to provide a Rahmenschalungs- corner system, with which a frame panel formwork can be constructed with less effort, in particular with a faulty placement of plugs and nuts is avoided in and on anchor holes.

Brief description of the invention

This object is achieved by Rahmenschalungs-Eck system, comprising

a) a frame formwork Inneneckelement, with two mutually angled, interconnected

Inner legs, each inner leg having on its outer side a flat formwork skin, the Schalhäute of the two inner legs enclose an angle α1, each inner leg having on an inner side a frame portion which extends along a lateral outer edge of the inner leg, which faces away from the other inner leg wherein each inner leg has at least one anchor hole passing through the Formwork skin of the inner leg runs, and whereby all anchor holes of an inner leg are removed from the

Frame portion of this inner leg are arranged,

b) a frame formwork Außeneckelement, with two mutually angled, rigidly interconnected

Outer limbs, each outer limb having on one inner side a flat form skin, wherein the two form skin skins of the outer limb enclose an angle α2, with α1 = α2,

and wherein the outer corner member is free of anchor holes,

c) two rectangular frame scarf elements, each of which is formed with a flat formwork skin on a front side of the frame formwork element, with a peripheral frame on a rear side of the frame formwork element, with at least one anchor hole which passes through the formwork skin of the frame formwork element, wherein all anchor holes of a Rahmenschaielements in a common armature hole plane are arranged, said anchor hole plane is centered between two parallel outer side edges of the rectangular Rahmenschaielements and perpendicular to the Schalhautebene, and wherein all anchor holes of a Rahmenschaielements removed from the peripheral frame are arranged, wherein the position of each anchor hole of each inner leg with respect to three lateral outer edges of the inner leg of the position of an anchor hole of a Rahmenschaielements respect to three lateral outer edges of the Rahmenschaielements corresponds and vice versa. The Rahmenschaiungs corner system according to the invention, as well as known frame corner systems Rahmenschalungs corner elements and rectangular Rahmenschalelemente. However, the positioning of the anchor holes is modified. The inventive frame formwork corner system is used to produce a corner of a concrete wall. It is further adapted to be continued on the inside and the outside with rectangular frame formwork elements with centrally aligned anchor holes; these continuing frame formwork elements are of the same type as the rectangular frame formwork elements of the frame formwork corner system according to the invention.

The anchor frame plane extends centrally between (ie, equidistant to) two of the outer edges of the rectangular frame formwork element A center anchor hole according to the invention replaces two anchor holes at opposite ends Frame sections of the prior art., Thus, the total number of anchor holes per frame formwork element can be significantly reduced.

Accordingly, the inner corner element of the frame formwork corner system according to the invention is adapted. In the mounted state, each inner leg is aligned with respect to its upper edge, lower edge and its lateral outer edge, which faces away from the other inner leg, a rectangular frame shell element. For each anchor hole in the inner leg, at exactly the same relative position (i.e., spacing) with respect to the outer edges, exactly one anchor hole is provided in the frame shell member. The same applies vice versa, i. for each anchor hole in the frame formwork element exactly one anchor hole in the inner leg is provided at identical relative position with respect to three outer edges of the frame formwork element.

As a result, all the anchor holes of the inner legs and all the anchor holes of the Rahmenschaleiemente can actually be used for an anchorage. Anchor holes in the immediate vicinity of anchor holes of an adjacent component (in particular frame scarf element), wherein only one of these two anchor holes is used for an anchor come at a Frame formwork corner system according to the invention not before. An overlap of anchor holes by anchor plates of adjacent anchor plates does not occur. In the frame formwork corner system according to the invention only anchor holes are present, which can actually be used in the construction of a frame panel formwork, and are typically in the

Frame of the invention, all anchor holes used for anchoring. In this respect, no plugs need to be set at all in the components according to the invention. An associated workload is thus eliminated. Since no plugs are set, it can not come to an incorrect placement of plugs.

In the same way according to the invention incorrect pre-assembly of nut elements in the one-sided anchorage is avoided. It is quite simple to place a nut element on each anchor hole on a formwork side (or side of the concrete wall to be created), i. be attached.

None of the anchor holes of a erfindungemäßen Rahmenschalungs- corner assembly is arranged in the frame. This gives the advantage that the anchor hole diameter - and thus the strength of the anchor rods - is arbitrary. In the prior art, the width of the peripheral frame limits the maximum anchor hole diameter. An increase in the anchor hole diameter would have to be accompanied by a general widening of the frame (with a constant frame profile), which would result in an expensive additional steel consumption in the production of the frame formwork element. When using the frame formwork corner system according to the invention therefore more costly formwork can be constructed cost. Larger anchor holes, as they are easily selectable in the invention, also allow a larger game for anchor rods, which is required for example in the manufacture of mutually tilted wall outer sides and corresponding mutually tilted formwork elements.

In many cases, a concrete wall made by a formwork is not further processed or clad before using the associated structure; in In this case one speaks of "fair-faced concrete walls." On an exposed-concrete wall, anchoring holes used for anchoring as well as stoppered anchor holes remain recognizable ("anchor pattern"). When using a frame panel formwork with Rahmenschalungs- corner elements according to the invention an improved, in particular more homogeneous anchor pattern is achieved with exposed concrete walls. Imprints of plugs can be dispensed with entirely, and the impressions of used anchor holes are conveniently located away from and centered between detectable joints. The impressions of the anchor holes used are regularly distributed over the exposed concrete wall.

In the context of the invention, all anchor holes are arranged not only outside the peripheral frame or frame section, but preferably also clearly spaced from the peripheral frame or frame portion of the component (frame formwork element or inner corner element). An anchor hole is in this sense clearly spaced from the frame when it is at least 8 cm from the frame, measured from the nearest frame inside edge to the center of the anchor hole and parallel to the scarfing plane.

Anchor holes in the sense of this invention are only those anchor holes that run through the formwork, typically approximately perpendicular through the formwork.

The present invention provides particular component systems for a

In the case of the central anchorage, all the anchor holes of a rectangular frame formwork element are each strung on an anchor plane which extends centrally between two lateral parallel outer edges and perpendicular to the scarfing plane of the frame formwork element 2007 004 225.8.

With the frame formwork corner system according to the invention and the formwork formwork T intersection system according to the invention, corners and T intersections of concrete walls can be produced, whereby the principle of the center anchorage can also be maintained in the area of the corner or T intersection. The central anchor has several advantages: 1) All anchor holes can also be used for anchorage; the setting of plugs is eliminated. This simplifies the construction of a frame panel formwork, in particular incorrect assembly is prevented. 2) The Ankerlochdurchmesser- and thus the strength of the anchorage - are freely selectable. This makes stronger anchors in particular possible without appreciable additional costs. 3) The anchor pattern on exposed concrete walls is significantly improved. All these advantages are combined with the flexibility of a frame panel formwork.

FIG. 1 shows in an exploded view a frame formwork corner arrangement according to the invention. The associated, arranged frame formwork corner system according to the invention comprises a frame formwork Inneneckelement 1, a Rahmenschalungs- Außeneckelement 2 and two rectangular Rahmenschalelemente 3, 4. In the mounted state border the Rahmenschalelemente 3, 4 directly to the Außeneckelement 2 and lie closer to the Inneneckelement (see see Fig. 3). All components of the frame formwork Eckanomdung have the same height H.

The inner corner element 1 has two inner legs 5, 6, on whose outer sides (facing the observer) in each case a planar formwork skin 5a, 6a is formed. The Schalhäute 5a, 6a abut at a common

Outside edge 7 to each other and include an angle α1 of 90 °. The two inner legs 5, 6 are constructed mirror-symmetrically to each other and formed together in one piece.

Perpendicular through the formwork skins 5a, 6a extend two anchor holes 8, 9 and 10, 11. The anchor holes 8, 9 of the inner leg 5 and are lined up parallel to a lateral outer edge 12 and parallel to the common outer edge 7; the anchor holes are (here) but closer to the outer edge 12 than to the outer edge 7. The anchor holes 10, 11 of the inner leg 6 are lined up in a similar manner.

In the frame shell elements 3, 4 anchor holes 13, 14 and 15, 16 are also formed. The anchor holes 13, 14 of the frame scarf element 3 lie on a common anchor hole plane, the center between two parallel outer edges 17, 18 of the frame shell element 3 and perpendicular to the Schalhautebene (the facing skin 3a is facing away from the viewer) of the frame scarf element 3 extends (see Fig. 9). In the same way, the anchor holes 15, 16 lie on a common anchor hole plane, which extends centrally between the parallel lateral outer edges 19, 20 and perpendicular to Schalhautebene 4a of the frame formwork element 4.

The anchor hole positions of the anchor hole 8 in the inner leg 5 and the anchor hole 13 in the frame formwork element 3 correspond to each other. This means that the distances a1, a2 and a3 of the anchor hole 8 from the three lateral outer edges 21 (upper edge), 12 (left outer edge, which faces away from the other inner leg 6) and 22 (lower edge) of the inner leg 5 are equal to the distances b1 , b2 and b3 of the anchor hole 13 from the lateral outer edges 23 (upper edge), 17 (left outer edge) and 24 (lower edge) of the frame scarf element 3.

In the same way correspond to the positions of the anchor holes 9 and 14, the anchor holes 10 and 15, and the anchor holes 11 and 16.

By corresponding anchor holes (such as anchor holes 8, 13) is an anchor with an anchor rod (not shown).

The outer corner element 2 comprises two outer legs 25, 26. On the inner sides of the outer legs (facing away from the viewer) are each flat Schalhäute 25a, 26a provided, which enclose an angle α2 of 90 °. At the back of the outer corner member 2 is reinforced by a peripheral frame 27, which also extends at an outer corner edge 28. The outer corner element 2 is mirror-symmetrical with respect to the outer legs 25, 26 constructed.

The frame scarf elements 3, 4 are also reinforced on their backs with a peripheral frame 29. The dash-dot line in FIG. 1 indicates aligned edges (see FIG. 3).

FIG. 2 shows the inner corner element 1 from FIG. 1 from the rear side. On the back of Inneneckelements 1, a circumferential frame 30 is also provided, which is additionally reinforced in the region of a corner edge 31. A part of the frame 30, namely the frame portions 30a, are needed for clamping adjacent frame scarf elements. Such a frame portion 30a extends - illustrated for the right inner leg 5 - at that lateral outer edge 12 of the inner leg 5, which faces away from the other inner leg 6.

The anchor holes 8, 9, 10, 11 are all clearly spaced from the frame 30.

It should be noted that an inner corner element made of a frame formwork T-junction system according to the invention is constructed in the same way as the inner corner element 1.

FIG. 3 shows a schematic, horizontal cross section through the frame formwork corner arrangement according to the invention of FIG. 1, at the level of the upper anchor holes.

The formwork skin 5a of the inner leg 5 of the Inneneckelements 1 lies opposite and parallel to the formwork 3a of the frame formwork element 3 and parallel (but only to a small extent directly opposite) to the formwork skin 25a of the outer leg 25 of the Außeneckelements 2. The same applies to the Schalhäute 6a, 4a and 26a. The lateral outer edges 12, 17 of the inner leg 5 and the frame shell element 3 are aligned, ie they end at a common edge plane R, which is perpendicular to the planes of the Schalhäute 5a, 3a. The same applies to the corresponding outer edges of the inner leg 6 and the frame formwork element 4 on the edge plane R '. The anchor holes 8, 13 are directly opposite, in particular, the distances a2 and b2 of the outer edges 12 and 17 are identical. The same applies to the anchor holes 10 and 15.

With the frame formwork corner system of FIG. 3, only one wall thickness WS (or a distance between the formwork skins 5a, 3a and 6a, 4a) can be constructed if the alignment at the outside edges (approximately 12, 17) is to be ensured. However, other wall thicknesses can, as shown in FIG. 4, be adjusted by means of second additional frame formwork compensation elements 32. The frame formwork compensation elements 32 are arranged between the outer legs 25, 26 and the frame formwork elements 3, 4 and widen the wall thickness WS by its width BA.

If only one compensating element 32 were used, then the wall thickness WS would change at the corner, which can also be realized with the present invention.

All components 51, 52, 53, 61, 62 have the same height H and each have a peripheral frame 54 at its rear. The Inneneckelemente 51, 52 are constructed as shown in Fig. 2.

The first inner corner element 51 has a first inner leg 55 and a second inner leg 56. Their frontal Schalhäute 55a, 56a (facing the viewer) intersect at an angle α1 of 90 °. The second inner corner element 52 has a first inner leg 57 and a second inner leg 58. Also their Schalhäute 57a, 58a (the formwork skin 57a of the first inner leg 57 is facing away from the viewer) also intersect at an angle α1 of 90 °.

The first frame formwork element 61 has a planar formwork skin 61 a, the second frame formwork element 62 a planar formwork skin 62 a and the frame formwork compensation element 53 a planar formwork skin 53 a (in each case facing away from the observer).

The Schalhäute 56a and 61a are opposite to each other and are aligned parallel to each other. Both Schalhäute have anchoring holes 63, 64 and 65, 66 whose relative positions correspond to each other: The anchor hole 63 in the inner leg 56 has spacings a1, a2, a3 to the three lateral outer edges 21 (top edge), 12 (left outer edge, from the other inner leg 55th turned away) and 22 (lower edge). The anchoring hole 65 in the first frame formwork element 61 has spacings b1, b2, b3 to the three lateral outer edges 23 (upper edge), 17 (left outer edge) and 24 (lower edge up). We have a1 = b1 and a2 = b2 and a3 = b3. In the same way correspond to the Ankeriochpositionen the anchor holes 64 and 66th

The Schalhäute 55 a and 57 a are parallel to each other and opposite. The anchor hole 67 corresponds in its relative position with respect to the distances to the outer edges 70 (upper edge), 71 (lateral outer edge facing away from the other inner leg 56), 72 (lower edge) in the formwork skin 55 a, the position of the anchor hole 69 in the formwork skin 57 a , The anchor hole 68 in the Formwork skin 55a corresponding Ankerioch in the formwork skin 57a is hidden in Fig. 5.

Furthermore, the shuttering skins 58a and 62a are parallel to each other and face each other. The anchor hole 73 of the second inner leg 58 corresponds in its relative position with respect to the distances to the outer edges 77 (top edge), 78 (right outer edge, which faces away from the other inner leg 57), 79 (lower edge) the anchor hole 75 of the second frame shutter member 62 with respect to Outside edges 80, 81, 82. The anchor hole 74 corresponds to the anchor hole 76th

The dash-dot line in Fig. 5 indicates aligned edges (see Fig. 6).

FIG. 6 shows a schematic cross section through the frame formwork T-junction arrangement according to the invention from FIG. 5, at the level of the upper anchor holes.

The frame shell elements 61, 62 directly adjoin the frame formwork balancing element 53 located therebetween. The associated formwork skins 61a, 53a, 62a lie in one plane. These formwork skins 61a, 53a, 62a bound to one side the continuous wall 84 of the T-junction to be manufactured. The three components 61, 53, 62 are engaged behind by a cross bar 85 and thus mechanically stabilized. The two Schalhäute 55a, 57a limit on both sides of the projecting wall 86 of the T-junction to be produced.

The lateral outer edges 12 and 17 of inner legs 56 and

Frame scarf element 61 are aligned on the edge plane R, as well as the outer edges 78 and 81 of the inner leg 58 and frame scarf element 62 are aligned at the edge R '. Finally, the outer edges 71 and 83 of the inner leg 55 and inner leg 57 are flush with the plane R ".

The pairwise corresponding anchor holes 63 and 65, further 73 and 75, and also 67 and 69 are immediately opposite.

The wall thickness WD of the continuous wall 84 can be adjusted by the distance between the two inner corner elements 51, 52 of the frame shell elements 61, 62 and the compensation element 53. The wall thickness WZ of the impinging wall 86, however, is determined by the width of the compensating element 53.

Different wall thicknesses WZ of the impinging wall 86 can be set in two ways: 1) for each desired wall thickness, a separate, special compensating element 53 is provided; or 2) the compensation element 53 is supplemented by one or more additional compensation elements 90, 91, 92, typically with standardized widths. This second possibility is illustrated in FIGS. 7 and 8. The additional compensating elements 90-92 are made of solid wood, for example, and are also engaged behind by the cross bar 85. In FIGS. 7 and 8, in each case all wall thicknesses were equally increased. Otherwise, the remaining components 51, 52, 61, 62, 53 correspond to the embodiment of FIG. 6.

Finally, FIG. 9 also shows a typical frame formwork element 3 with center-aligned anchor holes 13, 14, as can be used both in a frame formwork corner system according to the invention and in a frame formwork T intersection system according to the invention. Likewise, the illustrated frame scarf element 3 can continue a frame panel formwork starting from a Rahmenschaiungs corner system or -T- crossing system according to the invention. The frame formwork element 3 has a planar formwork skin 3a (facing away from the observer) on its front side and a peripheral frame 29 on its rear side. Furthermore, a reinforcing element 93 and various reinforcing struts 94 are provided on the rear side. In the reinforcing element 93 and by the formwork 3 are two anchor holes 13, 14th

All anchor holes 13, 14 are lined up on an anchor plane A, which runs between the parallel, lateral outer edges 17 and 18 with identical distances to these and perpendicular to Schalhalutebene SE. The anchor holes 13, 14 are further arranged mirror-symmetrically with respect to a cross-plane KE, which extends between the other, parallel lateral outer edges 23, 24 with identical distances to these and perpendicular to the Schalhautebene SE. The frame scarf element 3 is free of rear clamping beams, all supporting elements (frame 29, reinforcing element 93 and reinforcing struts 94) terminate in a plane parallel to the formwork skin 3a at a distance T. As a result, frame scarf elements 3 are well stackable.

The peripheral frame 29 also has some holes 95 which extend perpendicularly through the peripheral frame 3 and parallel to Schalhautebene SE. With these holes 95 could neighboring

Frame scarf elements 3 are fastened together. Furthermore, the holes 95 facilitate the stacking and unstacking of the frame scarf elements 3 with a corresponding chain suspension.

It should be noted that frame scarf elements with centrally aligned anchor holes are also possible with only one anchor hole or with three or more anchor holes, all arranged on the anchor hole plane A.

In summary, the present invention describes multi-component frame formwork systems, including

Frame scarf elements with centrally aligned anchor holes, with which based on a central anchor wall structures can be constructed, which go beyond a simple wall. An important component for all these Systems is in each case an inner corner element, which corresponds in at least one leg with its anchor hole positions a zughörigen, aligned frame formwork element with centrally aligned anchor holes. As a result, a central anchorage can be used or continued at corner points (real corners, T-intersections).
