Definitions

  • the invention relates to a formwork element for a slot wall for arrangement between a first created slot wall segment and an adjacent, to be created second slot wall segment, with a plank-shaped base body, which has a formwork side with a first formwork surface and a second formwork surface, between which a recessed relative to the two formwork surfaces Receiving bead is arranged, in which a sealing strip is arranged, which extends along the base body, according to the preamble of claim 1.
  • the invention relates to a method for producing a trench wall in the bottom of a plurality of vertical, juxtaposed slot wall segments, wherein first a first slot is created in the ground, which is filled with a curable composition to form a first slot wall segment, wherein after creating the first slot and before hardening of the mass to the first slot wall segment on at least one end face of the first slot a formwork element is arranged, according to the preamble of claim 10.
  • Diaphragm walls have been created for many decades, especially for securing construction pits.
  • individual slots are successively introduced into the soil, which are each filled with a curable material to form the slot wall. Since slot walls are often used as a sealing walls against lateral water ingress in excavations, it is necessary that the individual juxtaposed diaphragm wall segments abut tightly.
  • a so-called shuttering element after creating a first slot and filling the curable material in a side region.
  • the screed-like formwork element extends over the entire depth of the slot and provides for a defined side surface of the hardening slot wall segment.
  • the formwork element often also serves as an abutment or guide surface in forming the adjacent second slot for the adjacent slot wall segment.
  • U1 shows a formwork element, which has a along the plank-like body extending sealing strip. This protrudes to the side of the first slot wall segment whose side surface delimits the formwork element.
  • the sealing tape can be so firmly embedded in the thermosetting first slot wall segment.
  • the formwork element is detached and removed from the slot before curing to the second slot wall segment.
  • the formwork element is therefore also referred to as Abschalelement. In the free space can not penetrate hardened mass of the second slot wall segment, and thus form an intimate and tight connection to the first slot wall segment. From the EP 1 983 111 A1 goes out a formwork element of precast concrete.
  • a generic formwork element goes out of the DE 20 2011 051 438 U1 out.
  • This known formwork element can be used together with the reinforcing cage, which serves to increase the strength of the slot wall segment in the slot. It thus remains also in the slot wall, wherein the joint strip extends to the formwork side to the outside.
  • the elastic, sensitive sealing strip is damaged or even destroyed when inserting the formwork element in the slot or when digging the adjacent slot. This can affect the tightness of the diaphragm wall and thus the function as a sealing wall.
  • the invention has for its object to provide a formwork element and a method for producing a diaphragm wall, with which a slot wall with high density can be created in an efficient and reliable manner.
  • the object is achieved in that the receiving bead is covered by a cover element, wherein a receiving space is enclosed, in which the sealing strip is arranged.
  • a first aspect of the invention is thus to arrange the sensitive elastic sealing strip, which is also referred to as joint tape, in a protected receiving space, which is covered by a cover element.
  • the sealing strip which may be made of an elastic material or a thin sheet, protected during transport and insertion into the slot.
  • the cover element can then preferably be removed after creating the adjacent slot, so that hardenable mass, in particular concrete mass, flow into the receiving space and can flow around the sealing strip.
  • the cover element can jump forward or backward relative to the two shuttering surfaces, which preferably lie in one plane.
  • the cover element and the shuttering surface lie in one plane.
  • the cover element can be a rail or profile made of plastic or metal, which is removed in a separate operation. It is preferred according to the invention that the cover element is a film, a textile or a grid. These thin cover elements can be torn open after insertion into the slot and thus the receiving space can be opened. This can be done through the slot wall device which creates the adjacent slot.
  • the trench wall device may in particular be a trench wall grab. In principle, however, the use of a trench wall cutter is possible. A grid can also remain, since the hardenable mass can flow through the grid.
  • the receiving space is filled with flowable or pourable filling material.
  • the filling material is a gel, granules, sand or gravel or a mixture thereof.
  • the filling material ensures a secure covering of the sealing strip.
  • a counter-pressure in the receiving space is effected by the filling material, so that the formwork element can be used without problems even at a very thin cover element in greater depths, such as slot depths of 10 m and more.
  • the effluent fill material may be removed when creating the slot with the soil material or it may be a component of the curable composition.
  • the filler material can then be matched to the curable composition so that it supports the strength of the curable composition or at least does not sustainably reduce it.
  • a further preferred embodiment of the invention consists in that in each case one side wall section pointing from the formwork side is arranged on one side edge of the first formwork surface and the second formwork surface.
  • the formwork element with the two shuttering surfaces has a width which corresponds to the width of the created slot.
  • rearwardly facing side wall sections are arranged on the two outer side edges of the first formwork surface and the second formwork surface. These prevent or complicate a crucial flow around the coarse concrete mass and thus contamination of the formwork surface.
  • the formwork surface may serve as a guide surface for guiding the trench wall device when the adjacent second slot is created.
  • the shuttering element can be designed as a shuttering element which is removed from the slot again before the second diaphragm wall segment is set.
  • the main body has a fastening side facing away from the formwork side, to which the main body is fastened via connecting elements to a reinforcing element.
  • the reinforcement element is part of the formwork element and thus forms a unit.
  • the connecting elements may in particular be metal struts, wires or a bridging grid with which the basic body is fastened from a metal sheet to the reinforcing element made of metal, in particular welded thereto.
  • the fasteners can serve at the same time for stiffening the sheet metal body whose sheet thickness is between 1 mm to 5 mm.
  • the formwork element can thus in one operation with a steel beam, a reinforcement cage or be installed in the slot a differently shaped reinforcing element. It remains in the slot as a so-called lost formwork element.
  • a preferred embodiment of the invention is that the formwork element is formed with a length which is greater than a length of the reinforcing element and corresponds to the depth of the slot wall.
  • the formwork element can protrude downwards relative to the reinforcement element which serves to reinforce the slot wall segment.
  • the formwork element can thus serve for placing on the bottom of the slot, without the reinforcing element itself comes into contact with the bottom of the slot.
  • the reinforcing element can be arranged in the exact position within the curing diaphragm wall segment.
  • a further advantageous embodiment of the invention is that the formwork element is composed of several sections, which are fastened to each other along the reinforcing element with a defined distance.
  • the formwork element can basically be arranged on only one or both end sides of the reinforcement element.
  • the formwork element can be divided as a continuously formed screed or in sections. The sections may abut or overlap.
  • the dividing joints serve as joints.
  • the individual sections of the formwork element which may have a length of one meter to several meters, will hardly bend in this arrangement at a righting.
  • the invention further relates to a slot wall in the bottom of at least two vertical slot wall segments, wherein an inventive formwork element is arranged between the slot wall segments.
  • the slot wall is made up of a large number of such vertical slot wall segments which adjoin one another.
  • the formwork element according to the invention arranged, this particular is not pulled, but remains in the slot wall and thus firmly embedded in concrete.
  • the inventive method is characterized in that a formwork element is used according to the invention, wherein a receiving space is enclosed by a sealing strip on a formwork side.
  • a sealing strip as described above, be protected until installation and thus ensure a high tightness of the slot wall.
  • a preferred variant of the method is that after insertion of the formwork element with outwardly facing formwork side an adjacent second slot for forming an adjacent second slot wall segment is created, wherein a cover element is torn open on the formwork element for opening the receiving space and exposing the sealing strip or eliminated.
  • a cover element such as foil, geotextile, or mesh
  • cracking may be caused by the normal operation of a trench wall device as it lifts the adjacent slot.
  • a special mandrel or projection is provided on the trench wall device, which extends to the cover element and this targeted up or tears.
  • the hardenable mass flows from the adjacent second slot into the open receiving space around the sealing strip, wherein the sealing strip seals a joint between the two adjacent slot wall segments.
  • the protection of the sealing strip can be further improved by flowing filler material from the receiving space into the adjacent slot when the receiving space is opened.
  • the filling material in particular sand, granules, gravel or gel, envelops the sealing strip and also stabilizes the receiving space.
  • the filler material may be removed from the bottom or mix with the incoming curable composition.
  • the filler has a grain size which is larger than the grid openings.
  • the formwork element can be used separately in the slot. It is particularly economical that the formwork element in the first slot together is used with a reinforcing element to which the formwork element is attached. It is therefore only one operation for the insertion of the reinforcement cage and the formwork element necessary. It also eliminates a costly Abschalen and removing the formwork element from the slot.
  • a formwork element 10 is shown with a base body 12 made of a steel sheet.
  • the formwork element 10 has an approximately W-shaped shape.
  • a planar first shuttering surface 21 and a second planar shuttering surface 22 are arranged, between which a substantially U-shaped receiving bead 20 is formed, which rebounds towards the formwork side 14 to the rear.
  • an elastic sealing tape 18, also called joint tape is an elastic sealing tape, held.
  • the sealing strip 18 extends through the main body 12, so that it projects on the one hand with an inner sealing portion 17 into a receiving space 24 of the receiving bead 20 and on the other hand with an outer sealing portion 19 to a side remote from the formwork side 14 mounting side 16.
  • the sealing strip 18 may also be multi-part, in particular, the inner sealing portion 17 may be separated from the outer sealing portion.
  • the receiving space 24 is closed at the shuttering side 14 directed opening with a grid-like cover member 30.
  • the cover element 30 embodied as a grid is arranged flush with the first shuttering surface 21 and the second shuttering surface 22 and lies in a plane therewith.
  • Filter gravel is introduced as filling material 36 in the receiving space 24 thus closed.
  • the filling material 36 encloses and protects the sealing strip 18 in the receiving space 24.
  • the receiving space 24 is closed at the end faces by additional, not shown side cover elements.
  • the outer sealing portion 19 of the sealing strip 18 projecting from the base body 12 to the fastening side 16 is encompassed by a U-shaped bracket arrangement 32.
  • this open bracket assembly 32 connects the two halves of the substantially symmetrically constructed base body 12.
  • a first slot 3 is first created in a floor 5.
  • the slot 3 is filled with an only indicated hardenable mass 7.
  • the formwork element 10 according to the invention is inserted into the first slot 3, in particular when it is still filled with non-hardening supporting liquid according to the two-phase method.
  • the formwork element 10 is welded to a reinforcing cage as a reinforcing element 40 made of a steel grid via metallic connecting elements 44. In this way, the formwork element 10 can be lifted together with the reinforcing element 40 as a unit in the support liquid or in the still soft curable mass 7.
  • the formwork side 14 is located at the bottom 5 at a first end face of the slot 3, at which an adjacent second slot wall segment 2 is created.
  • the formwork element 10 has a width which corresponds to the width of the slot 3, wherein the side wall portions 28 extend away from the formwork side 14 along the longitudinal walls of the slot 3.
  • the side wall portions 28 prevent penetration of the hardenable mass 7 to the formwork side 14 of the formwork element 10.
  • the still flowable, curable mass 7 in the first slot 3 can flow around the reinforcement cage, the connecting elements 44, the open bracket assembly 32 and thus also the sealing portion 19 of the sealing strip 18 on the mounting side 16. Due to the arranged cover element 30 and the filling material 36, it is prevented that the hardenable mass 7 flows out of the first slot 3 into the receiving space 24.
  • a second slot 4 in the bottom 5 can be created in particular by means of a diaphragm wall gripper.
  • the diaphragm wall gripper can be guided along the formwork side 14 of the formwork element 10, in particular.
  • the excavation of the second slot 4 is carried out in a two-phase process with filling of the excavated slot 4 with a supporting liquid.
  • the flowable hardenable mass 7 later replaced the support suspension.
  • the grid-like cover element 30 can be torn open by the slot wall device.
  • the filling material 36 can flow from the receiving space 24 into the second slot 4.
  • Curable mass 7 from the second slot 4 can get into the tooth-shaped receiving space 24.
  • a form-locking toothing of the first slot wall segment 1 is achieved with the second slot wall segment 2, wherein the hardenable mass 7 flows around the inner sealing portion 17 of the sealing strip 18. In this way, the concrete joint between the first slot wall segment 1 and the second slot wall segment 2 is sealed by the sealing strip 18.
  • a slot wall can now be formed by creating further slot wall segments using the formwork element 10 according to the invention.
  • the formwork element 10 extends beyond the length of the reinforcement element 40 addition.
  • the formwork element 10 may be arranged on both end sides of the reinforcing element 40.
  • a one-sided arrangement according to Fig. 2 can be arranged on the opposite side of the reinforcing element 40, an additional foot element, so that the reinforcing element 40 at the bottom of a slot horizontally on the formwork element 10 and the foot element can be placed.
  • the formwork element 10 is formed by four sections 11, which are arranged adjacent to each other.
  • the sections 11 are each connected via connecting elements 44 with the reinforcing element 40.
