Definitions
- the invention has a structure with walls that with Concrete are built with essentially no composite, in particular tendons arranged outside the walls as well as a formwork for such a structure.
- Buildings are made of different materials, such as brick, concrete, metal, etc. the like ,. built up.
- d. H. the carrying capacity or also to increase tensile strength
- steel reinforcements can either be slack or pre-stressed exist in the structure. If a preload is applied, this way, compressive stresses are introduced into the structure Load before the building is loaded as such, must be compensated.
- Such tendons can be varied be trained.
- Such a tendon can a rod, for example made of steel, or with individual Wires.
- Such a tendon can then go out from one Plastic sheath, for example polyethylene sheath, surrounded be, the tendons in a corrosion protection medium, such as artificial greases can.
- tendons are for example in the EP 0 393 013 B1. These tendons can vary depending on Arrangement of strands of different cross-sections, such as circular, triangular, rectangular u. Like. Have.
- the tendons are fixed at their respective ends, u. on the one hand with an anchor head and on the other hand with a pulling head, which cooperate with corresponding presses during clamping.
- the tendons can either be in the walls, for example in a cladding tube, be arranged or outside the Walls are laid.
- the tensioning direction of the tendons can not only be longitudinal of a building, but also across it, for example at a bridge, be provided so that the width of a bridge is particularly easy to enlarge.
- the tensioning direction of the tendons can not only be longitudinal of a building, but also across it, for example at a bridge, be provided so that the width of a bridge is particularly easy to enlarge.
- With external tendons must pass through walls be, with no bond of the tendon to the wall of the building should occur.
- Around ensure that the tendons pass through a wall can be circular in cross-section in the formwork Pipes arranged.
- Such formwork has the disadvantage that tendons with a plurality of wires, strands or the like. can only be introduced with difficulty because one end several links usually separate individual Has tendons.
- an exact positioning of the tubular part difficult to carry out because there are no surfaces, along which a corresponding exact control and alignment is also possible.
- the object of the present invention is a structure with walls that are built with concrete and to create a formwork that allows tendons without to lead unwanted redirections through a wall, a exact alignment of the recess provided for the tendons allows and also allows the recess in the Keep the cross-section small so that there is no unnecessary weakening of the Load capacity of the building is effected.
- the structure according to the invention with walls that are constructed with concrete, with essentially composite-free, in particular tendons arranged outside the walls, z. B. with tendons constructed, at least whose Ends, especially in the walls, are fixed, and Tendons unconnected through at least one wall are guided through a continuous recess, there is essentially in that the cross-sectional area of the recess is at least one end larger than the inside, especially that the cross-sectional area of the recess increases from the inside to the outside, and the recess has at least one flat surface, which is led through the wall.
- the cross-sectional area of the recess By enlarging the cross-sectional area of the recess from the inside outside or the larger cross-sectional area is on the one hand easier passage of the tendons through the recess allows and on the other hand simply too large a dimension the recess, based on the tendons, avoided become.
- Through the at least one flat surface of the recess can be a precise alignment of the recess, for example appropriate formwork, as this Surface can be used for adjustment. Any are under walls Type of walls, e.g. B. walls, webs, cross members to understand.
- the recess has a rectangular cross section on, so accurate positioning over each of those in the Recess provided wall, while at the same time rectangular tendons a particularly low weakening the wall through the recess is present.
- the recess has a covering, in particular made of plastic, e.g. B. polyethylene, so the frictional forces between the walls of the recess and the tendons be kept particularly low.
- plastic e.g. B. polyethylene
- the formwork according to the invention for a building opposite formwork parts for a wall of the building being from one formwork part to the other formwork part a closed formwork is arranged in cross section, consists essentially in that the cross section in itself closed formwork at least at one end larger than in Inside is, in particular, that the cross-sectional area is from the inside increases towards the outside and has at least one flat surface, that leads from one formwork part to the other formwork part.
- the cross-sectional area of the self-contained Formwork enlarged from the inside out or on one Multi-part tendons can also be larger than the inside simply inserted and through through the formwork conditional recess.
- the at least one level Area that goes from one formwork part to another formwork part leads to a precise alignment of the formwork and thus the recess caused by the formwork. So can optical aids, such as laser beams and the like, are particularly simple be used.
- the wall 1 shown in Fig. 1, z. B. wall, Web, cross member, has a recess 2, the one Side 3 leads to the other side 4 of the wall 1.
- a penetration is formed in the wall, through which a tendon 5 is guided.
- This tendon has a rectangular cross section, which is slight is smaller than the central cross-sectional area 6.
- the openings of the Recess 2 have a cross-sectional area 7 that is larger than the central cross-sectional area 6.
- the lower surface 8 is flat, on which the tendon is not in contact, whereas the upper surface 9 is curved in a cylindrical shape.
- the curved surface 9 is continuously curved and is such arranged that the cross-sectional area of the recess from the outside decreases inside.
- the formation of the curved surface 9 can also be seen particularly clearly from FIG. 3, wherein Furthermore, the lower flat surface 8 can also be seen.
- the cross section of a formwork shown in Fig. 4 10 for the recess 2 clearly shows that two parts 10a and 10b are present, which are connected to one another via a weld seam 11 are connected.
- the formwork itself is made of high pressure polyethylene built up and remains in the wall after the concrete has hardened as lost formwork.
- the section of a formwork for one wall has formwork parts 12, 13 which are flat and through which the outer sides of the wall 1 be formed. These formwork parts are thin Formwork 14 connected through which the recess 2 is caused becomes.
- the formwork 14 is a lost formwork, so that the Tendons with particularly low friction in the recess can be led.
