Definitions
- the invention relates to a formwork element of a flat joint formwork with means for detaching or detaching adherent Concrete masses and circulating concrete in sections Production of a diaphragm wall.
- Diaphragm walls are an important component in basic construction and serve, for example, as construction pit enclosures, retaining walls for jumps in the terrain or as sealing walls for dams and landfills. It is characteristic of the design of diaphragm walls that an open bottom slot is constantly stabilized by refilled support. As is known, diaphragm walls are produced step by step in individual construction sections, each section forming a concreting unit. The diaphragm wall sections are usually separated from one another by storage structures. In the past, steel shuttering pipes were used as support structures, which were recovered after the concrete had stiffened, which means that the pipes could not be pulled until the concrete had set. Extremely heavy pullers had to be used to pull.
- a formwork of an end joint is a Section of a diaphragm wall described.
- the formwork for the end connection point of mold wall sections, which comprises a plate and a box mounted thereon, in cross section a longitudinal joint for inserting the connection point has and constructed from at least two parts and for successive connection in Is equipped with connecting elements in the longitudinal direction characterized in that the box faces each part reset a corresponding end of the plate and that the connecting elements from a connector are formed, which is essentially the same cross section has like the box and with the plates in question each of the parts is connectable by going into the break area the boxes are inserted in such a way that the Overlaps end areas of the plates.
- EP 0 402 247 B1 describes a method and a device to remove a seal adhering to the concrete wall section cast in the floor. The procedure is characterized in that facing away from the concrete Side of the seal a joint using a tool is carried out at a location above the joint Place is connected to the seal.
- a formwork element Flat joint formwork with means for pressing the formwork element of the hardening concrete in section-by-section production described a diaphragm wall in which the base body of the formwork element arranged on the concrete side elongated recesses is provided, in which hydraulic or pneumatically actuated pistons are arranged, the Seal the recesses on surfaces facing the concrete.
- the invention has for its object a new formwork element a flat joint formwork with means for detachment or blasting off adhering concrete masses and in particular of circulating concrete in the section-by-section production specify a diaphragm wall, as well as a rational Process for its expansion, which are known to each other Means and processes through special efficiency and uncomplicated Handling when detaching or blasting more adherent Mark concrete masses and thereby the construction progress promote and that when sealing diaphragm wall sections overcome the resulting difficulties better and facilitate the progress of the work.
- the release agent or blasting agent are designed in the form of a spreading device, and that the formwork element has a base body arranged on the concrete side and surface parts forming vertical guide elements has, between which one on average one horizontal plane U-shaped, with the back shaped and non-positively against the concrete mass, for receiving the spreader with a vertical passage trained Pressure body in the horizontal direction between the Surface parts of the guide elements, with these in a form-fitting manner, is displaceably arranged.
- Figure 1 shows a formwork element of a flat joint formwork 8 with means for detaching or blasting off adhering Concrete masses 10 and (not shown) from circulating concrete the section-wise production of a diaphragm wall.
- the Formwork element has a base body 1 with a concrete side arranged and vertical guide elements 2 forming Surface parts 3, between which one on average one horizontal plane x-x U-shaped, with the back formund non-positively against the concrete mass 10, for Inclusion of a spreading device 4 with a vertical Passage 5 formed pressure body 6 in a horizontal Direction between the surface parts 3 of the guide elements 2 and is arranged such that it can be displaced in the positive connection.
- the formwork element is together with one from above loosely usable expansion body 4 as an integrating functional unit the flat joint formwork 8 is formed. Further One embodiment provides that the spreading device 4 on the one hand with a horizontal axis in a friction-locked system on the base body 1 of the flat joint formwork 8, and on the other hand on the inner wall of the pressure body 6 for blasting of the formwork element or base body 1 of adhesive Concrete mass 10 is formed.
- FIG 3 shows an advantageous embodiment of the invention, several spreaders 4 preferably in cooperation with a lifting device 12 to one another Unit 9 connected in the form of a push-off carriage are.
- the spreading device 4 can be a hydraulic one or pneumatic piston / cylinder unit. It but should not be ruled out with the invention, that the spreader 4 also with an electromechanical Spindle drive can be formed.
- the formwork element of a flat joint formwork 8 is particularly suitable for Use in the construction of a diaphragm wall and for sections Progress by incorporating one according to claims 1 up to 6 trained, which can be assembled from formwork elements Flat joint formwork 8 and thus solves in an optimal manner the task at the beginning.
