Definitions

  • the invention relates to a formwork device for the production of arcuate boundaries of wall recesses with a support device for a formwork skin.
  • the object of the invention is to provide a formwork device for arches, with which all types of arches common in construction can be produced quickly and precisely.
  • the object of the invention is achieved by means of a central vertical and preferably telescopically adjustable support strut and two pivotable holder arms projecting laterally on both sides of this support strut, each with a lower and upper cross strut, which together with connecting elements form a parallelogram at the ends and which together with the vertical support strut Wear elastically deformable formlining, loosened.
  • round arches, basket arches, pointed arches and segment arches in all radii as well as isosceles and isosceles arches can be produced.
  • the production of vaults by joining several elements is also possible.
  • the holder arms according to the invention have clamps at their free ends which are always at an angle to the vertical support. Thanks to the parallel struts of the parallelogram of the holder arms, a perfect radius determination of all types of bends is always guaranteed. The ability to move the lower cross strut and various formlining clamps make it possible to cover all inclinations and types of bends with one and the same formwork device.
  • spans of 60 cm to 1.60 m can be produced without changing the system.
  • FIG. 1 shows a schematic elevation of an apparatus according to the invention
  • FIG. 2 shows view B of FIG. 1
  • Fig. 3 shows view A of Fig. 1
  • Fig. 4 shows schematically the setting of the device for a pointed arch
  • 5 shows a side view of the formwork skin in the area of the clamp
  • FIGS. 6 to 8 schematically show elevations of the formwork device according to the invention for producing different arches.
  • the essential parts of the formwork device according to the invention are the vertical support strut 1, the formlining 2 and the two protruding laterally from the support strut 1 Retaining arms 3.
  • the formwork skin 2 is elastic, but has sufficient internal stress to support the in-situ concrete or masonry that rests on it. Suitable materials for the formlining 2 are PVC, plastics, steel, wood.
  • the formlining 2 is held by clamps 4, 5 both at the top of the vertical support strut 1 and at the free ends of the holding arms 3. Instead of the clamp 4, however, a fixed connection between the formlining 2 and the support strut 1 could also be provided.
  • Each of the two holding arms 3 is formed by lower cross struts 6 and upper cross struts 7, which together with holding plates 8, 9, form a parallelogram.
  • the holding plates 8 are fastened to the vertical support strut 1 by means of a flange 10 and a tension clamp 11.
  • the upper cross struts 7 are supported by bolts 12 in the holding plates 8.
  • the lower cross strut 6 is supported by a pin 13 in a circular guide 14 in the respective holding plate 8, the circular guide 14 being formed, for example, by a slot.
  • the holding plates 9 are created by means of axes 15 on the lower and on the upper cross strut 6, 7.
  • a support plate 16, which carries the clamp 5, is rotatably mounted on each holding plate 9.
  • the clamps 4, 5 have U-shaped brackets 17, 18 which encompass the formlining 2. On the side webs of the U-shaped bracket 17, 18 inwardly directed hooks 19, 20 are formed, on which clamping parts 21, 22 engage.
  • the clamping parts 22 are formed by a clamping bar 23 and a clamping screw 24.
  • the clamping screw 24 By turning the clamping screw 24, the clamping bars 23 are moved in the direction of the double arrow of FIG. 3, whereby the formwork skin 2 is either clamped or released.
  • the clamping parts 21 are formed by rotatable levers 25 which can be pivoted in the direction of the double arrow of FIG. 2 by means of screws 26 which are supported on abutments 27, as a result of which the bracket 17 is either clamped or released.
  • 1 shows the formwork device set for formwork of a round arch.
  • the formwork device according to the invention is converted for use in formwork of a segment arch.
  • a split formlining 2 ' is preferably used, which is held at the tip of the support strut 1 by holding parts 28 which are connected in a hinge-like manner via a joint 29.
  • the formwork device according to the invention can be arranged between vertically aligned formwork panels which laterally limit the sheet to be produced.
  • vertical supports 30 can be provided, which form the outer limits for the arch.
  • a further display plate with a scale can be provided, by means of which the precise angle setting of the holding arms 3 can be adjusted.
  • the formlining 2 in the area of the clamp 5 can facilitate a scale 31 or holding arms 3 and thus the adjustment of the radius of the arc.
  • the object of the invention is based on the principle that a formwork skin suitable for this is held by 3 pieces of clamps at the top, left and right. Due to the fixed clamping of the formwork skin at the 3 clamps and through a displaceability of the support arms along the middle support as well as a displaceability of the horizontal strut, every type of arch can be manufactured quickly and precisely. Additional arrangement of the formwork skin is no longer necessary due to the arrangement of the 3 clamps.
  • Wood, plastic or metal can be used as the material for the formwork skin.
  • plan 1051A40 instead of the swivel arms arranged as a parallelogram, as shown in plan 1051A40, individual support arms, scissor-shaped (plan 1053A40) and open parallelograms (plan 1054A40), which are either fixed or slidably connected to the center support, can be used.
  • the holding arms can be attached to the upper end of the support by inverting the basic principle.
  • the multi-functionality is achieved through the adjustability of the lateral holding arms and the horizontal support.
  • the side swivel arms are now loaded on "train", a correspondingly dimensioned chain is preferably used as the holding mechanism or an adjustable sliding arm is used according to plan 1052A40.
  • the various arch radii and spans are achieved by the telescopically adjustable horizontal strut (plan 1051A40).
  • the holding arms according to the invention hold clamps at their free ends, which are always at an angle to the vertical support. Due to the displaceable cross struts of the holding arms or the horizontal alignment of the cross strut when using the individual support, a perfect radius determination of all types of bends is always guaranteed. Due to the possibility to move the horizontal cross strut as well as the holding arms, as well as various formlining clamps, it is possible to cover all inclinations and arch types with one and the same formwork device.
  • spans of 0.60 m to 1.60 m can be produced without changing the system.
  • conventional steel supports such as are used on construction sites, are used for the vertical support strut.
  • supports made especially for the purpose of support, in particular those with a central guide for moving the horizontal strut, can also be used.
  • the essential parts of the formwork device according to the invention are the vertical support strut 1, the formwork skin, the formwork skin 2 and the two displaceable holding arms 3 projecting laterally from the support strut 1.
  • the formwork skin 2 is elastic, but has sufficient internal stress to support the in-situ concrete or Bear masonry. Suitable materials for the formlining 2 are PVC, plastics, steel and wood.
  • the formlining 2 is held by clamps 4 both at the top of the vertical support strut 1 and at the free ends of the holding arms 3. Instead of the clamp 4, however, a fixed connection between the formlining 2 and the support strut 1 could also be provided.
  • Each of the two holding arms 3 is held by adjustable support devices 5, which together with the formwork clamp 4 form the arch structure.
  • the holding arms 3 are attached to the vertical support strut 1.
  • a formwork clamp 4 is rotatably or permanently mounted.
  • the terminals 4 are designed as in VARINATE A.
  • Plan 1051A40 shows the formwork device set for formwork of a round arch.
  • the formwork device according to the invention can be arranged between vertically aligned formwork panels which laterally delimit the sheet to be produced.
