Description

The invention relates to a formwork and drainage element for manufacture development of structural parts from in-situ concrete, in particular for manufacturing of vertical building sections arranged in the ground.

For numerous applications, structural parts are immediately future location made of concrete. The so-called "in-situ concrete" can are formed with different types of scaffolding or formwork, e.g. B. to a floor slab for a building, to a retaining wall or to a lane. First, however, the excavation for the emergency manoeuvrable excavation pit or terrain modeling, which the Fastening the formwork elements in the grown soil closes.

In order to prevent the development of pressing water, there is one Drainage of the floor on the outside of the concrete is necessary. Therefore must be installed on the structure after completion in the ground cut a drain before filling, preferably drainage layers and drainage pipes. Appropriate construction cal requirements are laid down in various standards, at for example in the German standard DIN 4095.

For the practical implementation of this standard, for example vertical sealing of walls against seepage water according to DE 196 09 267 A1 suitable. A concrete fitting for drainage tion of buildings is the subject of DE 36 17 471 A1. Finally becomes a combined formwork and drainage element for production  of in-situ concrete building parts arranged in the ground in the Document DE 296 16 080 U1 described.

Provided both the formwork and the drainage work properly To be carried out properly will be a long-term and effective protection of the respective structure. However, it is disadvantageous the considerable amount of work and costs incurred by the technolo Machining and resting times in the excavation cycle Formwork / concrete entry / formwork / drainage / filling ent stands.

The object of the invention is to provide a device which for at least two different steps in creating the Sections of building components made of in-situ concrete arranged in the ground can be used while meeting the requirements of DIN 4095 Fulfills.

This task is solved by using a formwork and drainage element Hollow body is designed and a first vertical, the construction Workpiece associated section, which at its upper and lower longitudinal edge each in approximately horizontal Ab cuts passes through a second vertical, to the first vertical section with approximately parallel section are connected to each other, the upper horizontal section meh has more openings, while the lower horizontal section is fully designed.

Here, the first vertical Ab assigned to the building part cut in a manner known per se as formwork for the concrete used. The decision required so far below  However, len can be omitted. The one in the top horizontal section designed openings allow the inclusion in the ground penetrating surface water into the cavity and can follow to act as drainage. Thanks to the full surface design tion of the lower horizontal section can from the cavity absorbed water can be stored and forwarded. Purpose moderate designs are the subject of claims 2-6.

The proposed technical solution thus realizes the work steps shuttering and drainage with just one component. The conventional cycle of excavation / formwork / concrete entry / off peeling / drainage / filling is advantageously shortened, the There is no need to remove formwork.

An embodiment of the invention is described below with reference to Drawing described:

The formwork and drainage element 1 is used for the production of steep building from in-situ concrete, for. B. for a retaining wall, a road or - as shown in the drawing - for a floor plate 2 of a building. Following excavation of the site, the Ele are elements 1 according to the intended contour of the structural component in the natural ground mounted, being shown in the drawing only one element. 1 The attachment in the ground can be done in a conventional way with ground anchors. An advantageous BEFE stigung is achieved if the element 1 has guide sleeves 3 for receiving floor anchors, not shown. In each case, the element 1 is only used to form vertical, in the earth richly arranged building sections 2 , but not for building sections that are above the Erdden dens after completion. The formwork and drainage element 1 is designed as a hollow body and has a first vertical section 4 . This section 4 is assigned to the building part 2 and acts as formwork wall for its vertical area. Section 4 merges into approximately horizontal sections 5 and 6 on its upper and lower longitudinal edges. Sections 5 and 6 are connected to one another on the side opposite section 4 by a second vertical section 7 . This connecting section 7 runs approximately parallel to the first vertical section 4 .

The lower horizontal section 6 is designed over the entire surface. In the upper horizontal section 5 , however, several openings 8 are provided which are suitable for receiving leachate. It is also expedient if the second vertical section 7 facing away from the structural part 2 also has a plurality of openings 9 . These openings 9 are particularly suitable for receiving pressurized water. The openings 8 and 9 are preferably assigned filter elements which are not shown in the drawing.

The stability of the formwork and drainage element 1 is improved if stiffening ribs 10 are arranged in the interior or on the vertical end faces which run steeply 2 perpendicular to the building. These stiffening ribs 10 can have different geometrical contours. It is essential for the functionality of the element 1 , however, that a flow cross-section is guaranteed.

For connection to other elements or for connection to existing drainage elements, the element 1 has on its vertical, perpendicular to the structural part 2 end faces Koppelele elements, which are not shown in the drawing. The coupling elements can be designed differently, but they must always ensure a watertight connection of the element 1 with further elements 1 or with drainage pipes known per se.

After the concrete filling has been poured in and hardened sufficiently, building part 2 is filled in accordance with DIN 4095. Element 1 remaining in the ground is now effective as a drainage element. Thus, a combination of the formwork and drainage functions is achieved by just one component, which results in considerable labor and cost savings.
