Definitions

  • the invention relates to a method for manufacturing a concrete building component with a number of plate-like parts standing at a mutual angle.
  • a component is for instance a building element with the cross section of a number of stair steps.
  • Prefabrication of concrete elements with a relatively small wall thickness and a number of plate-like parts standing at a mutual angle has up to the present not been possible to a sufficient level of quality.
  • the invention now has for its object to provide a method with which such a concrete building component can be manufactured in one operation.
  • each section is successively filled under optimum conditions and each section thereby acquires a good quality.
  • the total building component will therefore likewise have the desired good quality.
  • the method of claim 2 is preferably applied. It has been found that with applying of this step the desired quality can be achieved under practically all conditions. Air inclusions in the mould which can result in cavities in the component are effectively prevented.
  • the invention likewise relates to and provides a device for manufacturing a concrete building component having a number of plate-like parts standing at a mutual angle.
  • this device comprises a frame, a mould mounted hingedly on the frame and having a mould space with corresponding plate-like sections which corresponds with the shape of the building component, which mould space has a pouring opening at the top, a concrete pouring device disposed above the pouring opening, drive means for tilting the mould into a desired pivot position and control means for the drive means.
  • the mould is placed each time in the correct pivot position with the drive means so that the section of the building component being poured at any moment is filled under optimum conditions.
  • the device according to the invention preferably comprises the step of claim 6.
  • the respective optimum pivot positions of the mould can be predetermined and input into the program memory of the control means. During production the correct sequence of pivot positions is hereby adjusted each time in well reproducible manner.
  • Fig. 1 shows an example of a concrete building component which can be manufactured with the method and a device according to the invention.
  • Fig. 2 shows a cross section of a device according to the invention for manufacturing the building component of fig. 1.
  • Fig. 3 shows the device of fig. 2 in another operating position.
  • Fig. 4 shows the device of fig. 2 in the position for removal of the formed building component.
  • the building component 1 shown in fig. 1 is a comparatively thin-walled element with a stair-like cross section of three treads.
  • the building component 1 can for instance be used in the building of a stadium.
  • the building component 1 has a number of plate-like parts 2-7 standing at a mutual angle.
  • the parts 2, 4 and 6 form the treads and the parts 3, 5 and 7 form the rise portions of the stair profile.
  • a protruding edge 8 is formed as an extension of each part 2, 4, 6.
  • Fig. 2 shows a device 10 with which the building component 1 of fig. 1 is manufactured.
  • the device 1 comprises a frame 11.
  • a mould designated integrally with 12 is connected hingedly at 18 to the frame 11.
  • Mould 12 consists of a left mould part 15 and a right mould part 16, each supported by respectively a left mould support construction 13 and a right mould support construction 14.
  • the two mould parts can also pivot relative to each other on the pivoting point 18 in order to enable removal of the formed building component from the mould. This removal will be further described with reference to fig. 4.
  • Mould 12 comprises between the left and right-hand mould parts 15, 16 a mould space with plate-like sections corresponding with the plate-like parts 2-7 of the component 1 for forming.
  • plate-like sections are designated with the same reference numerals as the corresponding plate-like parts of the component.
  • the whole mould 12 is pivotable on the hinge 18 by drive means, which here take the form of hydraulic jacks 20, 21.
  • the concrete building component 1 is formed as follows. In the position shown in fig. 2 a quantity of concrete sufficient to fill the plate-like section 2 is poured into the mould space via the pouring opening 7. As can be seen, the plate-like section 2 is practically vertical, so that the supplied concrete can effectively displace the air out of section 2. As soon as the correct quantity has been poured into the mould space the poured concrete is compacted with vibrating equipment (not shown) mounted against the mould.
  • the whole mould 12 is tilted into the position shown in fig. 3.
  • the section 3 herein comes to lie, in view of the shape of the element, at a minimal angle relative to the vertical. For good operation this minimal angle generally amounts to a maximum of 45°.
  • the mould 12 is herein positioned such that the straight line 30 between the pouring opening and the plate-like section 3 for filling encloses a minimal angle with the vertical.
  • the mould 12 is then tilted back again into the position shown in fig. 2 and section 4 is poured.
  • section 5 the mould is tilted once again into the position of fig. 3 and, for the sections 6 and then 7 the mould is again placed in the position of fig. 2.
  • the end surface at the position of the pouring opening 7, which end surface forms a side wall of the section 7, is finished and the concrete is given the opportunity to cure.
  • the tilting also has the effect that concrete which may not have flowed fully downward during pouring of a particular section is released again by the tilting and flows further.
  • platforms 27 and 26 are arranged on respectively the left-hand mould support 13 and the right-hand mould support 14. Platform 26 is horizontal in the position of fig. 2 and platform 27 is horizontal in the position of fig. 3. These platforms are used by the personnel filling the mould.
  • the pivot position of fig. 3 can be determined by a suitable dimensioning of the jack 21. This pivot position can just be reached in the end position of jack 21. This possibility is provided here because only two positions are required since the sections of the component 1 stand only at two different angles.
  • an angle sensor can be connected to the mould and the drive means 19 can be controlled by a control device (not further shown) such that a position detected by the angle sensor is adjusted in each case.
  • precisely the quantity of concrete is carried into the mould space as is required to fill a particular section.
  • This can be determined in simple manner by providing the concrete pouring device (not shown) with a weighing device.
  • the volume of a particular section can be determined simply by calculation and the weight of the required quantity of concrete can therewith be determined.
  • the control device (not shown here) is preferably a programmed control device which controls the successive operating commands for pivoting the mould into the correct position and feeding the correct amount of concrete. Switch-on of the vibrating means can likewise be carried out by the control device.
  • the tensioning devices such as 28 are first released.
  • the right-hand mould part 15 is hingedly connected at 23 to support arm 22. Due to the described pivoting movement of support arm 22 on the hinge 18, wherein the end of the locking pin position 24 is displaced to 25, the pivoting point 23 and thus the whole right-hand mould support with mould will move downward relative to the left-hand mould support through a distance at least equal to the protruding edges 8.
  • the right-hand mould part can then be pivoted clockwise by retracting the jack 21.
  • the left-hand mould part is pivoted counterclockwise so that the position of fig. 4 is eventually obtained.
  • the formed concrete building component 1 can then be removed simply from the mould.
