Definitions

  • the invention relates to a circuit element in the manner of a hollow block component with end faces lying at an angle of 45 ° to one another for use in conjunction with essentially cuboid formwork elements, the lengths of which are integral multiples of a certain grid dimension.
  • Formwork elements of this type are known, for example, from US Pat. No. 4,439,967, the end walls and intermediate webs of the formwork elements also corresponding to European Patent Application 83 1 00 967.5. can be trained. If you erect a building with walls that are only at right angles to each other with rectangular blocks or formwork elements, you can lay a network with a grid length corresponding to the grid dimension over the construction plan and you will then find that all joints between the blocks or formwork elements are under the threads of the network lie. Difficulties only arise when building with sloping walls and keeping the grid dimension.
  • the latter is particularly important in the case of formwork elements which are provided with matching grooves and projections on their upper and lower surfaces, so that they can be plugged together to form a wall formwork which is sealed on both sides.
  • the size and arrangement of the grooves and protrusions is adapted to the grid size.
  • the formwork elements can be separated in a grid dimension, and the divided webs then again matched the end walls of the formwork elements, as well as these have upper and lower recesses and can optionally remain open to hollow chambers in adjacent formwork elements or can be closed using suitable locking pieces will.
  • the formwork elements that are used for inclined walls have to match as closely as possible those for the longitudinal and transverse walls.
  • the known formwork elements for the production of angled transitions between diagonally abutting walls have the disadvantage that when using formwork elements with lengths in the grid dimension, both for the longitudinal and transverse walls and for the inclined walls result in one or the other gaps, i.e. the corners of the sloping walls do not lead to the corner points of the longitudinal and transverse walls falling into the grid of the grid.
  • the gaps have to be sealed temporarily and in time-consuming manual work, so that wall cladding is sealed on both sides.
  • Another disadvantage is that there are continuous joints at the corners from top to bottom. However, it is desirable to lay them together, i.e. with joints staggered from row to row.
  • the invention has for its object to provide a formwork element of the type mentioned, by which the disadvantages mentioned above are eliminated, so that longitudinal and transverse walls can be produced in conjunction with walls inclined at 45 ° and as a result of the smooth transitions spiral stairs can be simplified.
  • a formwork element with two legs of different lengths that enclose an angle of 135 °, the lengths of which on the shorter outside are products of a whole number and the grid dimension plus a length allowance, which is equal to the multiple grid dimension of the longer leg, multiplied by the factor o, 0 36.
  • the new formwork element with its two legs extends a bit from the longitudinal and transverse wall into the sloping wall. It therefore only requires two different formwork elements with legs of the same length, but a bend once to the right and in the other case to the left, in order to move the formwork elements over the corners between the longitudinal wall and the inclined wall and between the transverse wall and the inclined wall with rows of staggered joints, i.e. to be able to put together.
  • a prerequisite for this success is that both the longer and the shorter leg of the angular new formwork element are designed with the same length allowance.
  • the normal pattern of the grooves and protrusions should be from the free ends of the legs of the formwork element up to a distance corresponding to the length allowance at the kink of the formwork element be introduced.
  • there may then be further grooves and projections which, as seen from the kink point, must match in both legs, like the normal grooves and projections.
  • the aforementioned proportionality factor of o, o36 for dimensioning the length allowance relative to the length of the larger leg of the formwork element is based on the assumption that a relatively short inclined wall, as is often used for chamfering the corners of stairwells and for bay windows, is twice the length corresponds to the larger leg of the new angular formwork element.
  • the sloping wall in every second row of the formwork elements can be produced from two formwork elements which adjoin one another with their larger legs. In the rows of formwork above and below In this case, the sloping wall is formed at the ends by the short legs of angular formwork elements and cuboidal formwork elements arranged between them in grid dimensions.
  • the specified factor of o, 0 36 can be using the Pythagoras equation of an isosceles, right-angled triangle with the inclined wall are calculated as the hypotenuse. The exact amount is
  • the known formwork elements of the type mentioned have a grid dimension of 125 mm of the grooves and projections on the top and bottom sides of a grid dimension of 25o mm for the division of the hollow chambers, intermediate webs and end walls.
  • For the invention can be based on the smaller pitch of the grooves and projections.
  • the relatively large pitch of 25o mm for the inner hollow chambers and webs means that one would normally have to keep a relatively large distance from the corners of the bay window with bay windows.
  • the staircase in the 900 area of the corner has two identical and two mirror-symmetrical steps, the width of which on the outer edge is equal to the length of the larger leg of the formwork element and the surface of which is a right-angled triangle with the outer edge as a cathete. If the steps with the top and bottom are of the same design, in this case a single shape is sufficient for this step to produce all the steps in the spiral area. In this area, the levels usually have several different cuts.
  • the building shown in FIG. 1 in a partial section has an outer longitudinal wall 10 and transverse wall 12 and an inner longitudinal wall 14 and transverse wall 16. While the two inner walls 14, 16 abut one another at right angles, an inclined wall 18 extends between the outer walls 10 and 12. through which the more normal as from the walls 1 0 , 12 formed corner is chamfered. Said walls bear steps that indicated by dashed lines in 9 0 0- region of the corner and are labeled with 2 0, 22, 24 and 26th As can be seen, steps 2o and 24, and steps 22 and 26 each have the same surface. Levels 2o and 24 on the one hand and 22 and 26 on the other hand are mirror-symmetrical.
  • the staircase has eispielsfall B 'between the parallel walls 1o and 14 and between the parallel walls 12 and 16 have a width of one meter.
  • the outer walls 1 0 , 12 consist of known formwork elements made of insulating foam, which are stacked together in rows and then poured out with concrete.
  • the usual length of the formwork elements used for the outer walls 1 0 , 12 can be, for example, one meter, the division into inner hollow chambers and intermediate webs offering the possibility of cutting through the rectangular formwork elements with a grid dimension of 25o mm in order to obtain shorter formwork bodies, which are also are stable in themselves and can be completed at each end.
  • two new angular formwork elements 28 and 3o are used, each having a long leg 32 and a short leg 34 and differing only in that the short leg 34 in one case to the right and in the other case to the right is angled to the left of the long leg 32. Because of the agreement, it is sufficient to describe the formwork element 3o with reference to FIG. 2.
  • the formwork element is 3o in a known manner from two parallel side walls 36 and 38 by end walls 4 0, 42, a dual intermediate web 44 and a simple gutter 46 in the long leg 32 and a double gutter 48 in the bend are interconnected.
  • the end walls and intermediate webs have upper and lower recesses in a known manner, so that concrete can flow from one hollow chamber to the next and from one formwork element to another.
  • the recesses in the end walls 4 0, 42 can be closed by means not shown closure pieces which are to be brought into engagement with the end walls, in known manner.
  • the pattern of the rib-shaped projections 5o shown on the top of the side walls 36, 38 and a corresponding pattern of matching grooves on the bottom of the side walls 36, 38 are also known.
  • the projections 5o and corresponding grooves have a grid dimension a of e.g. 125mm.
  • the length of the larger leg 32 is preferably 4 times the grid dimension a plus a length allowance d entered next to the kink.
  • the short leg 34 has the length of a grid dimension a plus the same length allowance d, which is also arranged next to the kink.
  • the length allowances d have a dimension of 18 mm each for the lengths of the legs 32 and 34 mentioned in the example.
  • the outer corner of the formwork element 3o is rounded in the manner shown over the kink angle of 45 °, the pattern of the ribs 5o and corresponding grooves being matched to that of the straight regions of the legs. With respect to the bisector, there is mirror symmetry with respect to the ribs and grooves.
  • Two dividing lines 52 and 54 are entered in FIG. 2, in which the longer leg 32 can optionally be severed.
  • the dividing line 52 is at a distance of 2a from the end of the longer leg 32.
  • two individual, shorter formwork elements are formed, the end walls of which can optionally be closed by the closure pieces mentioned, because the separation of the double intermediate web 44 results in the middle two end walls which correspond to the end walls 4o and 42.
  • the intermediate web 46 is a special feature in that it is spaced apart from the neighbors by only essentially one grid dimension beard double intermediate webs 44 and 48 is arranged, while in the normal cuboid formwork elements, the centers of the intermediate webs are at a distance of 2a.
  • the additional simple intermediate web 46 offers a simple possibility of making a window reveal after the severing at the dividing line 54 and the closing of the recesses in the intermediate web 46 at a relatively close distance of only slightly more than the grid dimension a.
  • the width and height of the formwork element 3o are twice as large with the double grid dimension 2a as in the known formwork elements. Since the rest of the design corresponds to these, further views are not necessary.
  • the invention and the exemplary embodiment deal with the particularly frequent case of relatively short oblique turns which meet the adjacent longitudinal and transverse walls at 45 °. It is understood that the teaching of the invention can also be used at other angles, for example 6 0 ° and 3 0 °, a different length allowance to be calculated in the same way being taken into account. It is also evident that the invention is not limited to the fact that the two legs of the angular formwork element have an aspect ratio of 4: 1 without taking into account the length allowance d.
  • the larger leg could be longer or shorter in the grid dimension and the shorter leg could be chosen longer in the grid dimension, however, if the inclined wall 18 is extended by inserting cuboid formwork elements between the two long legs of the angular formwork elements 28, 3o, the calculation the length allowance with the proportionality factor of o, o36 half the multiple of the pitch of the sloping wall is to be used.
  • the short leg can also be shortened to dimension d.
