Description

35 40 45 50 55 60 65 70 447 004 2 It has proved possible to produce tracks of good quality. tetpmed so-called battery procedure. This is characterized by that you make several tracks in one large form at once. Thereby the cost of molding and molding work will be less. Still however, the problem remains to get these paths linear. This has solved, according to the invention, in such a way that the webs are formed of parallel adjacent pipes. These are stirred outer sides then become lateral boundary surfaces in the shape of betdngen. By placing these tubes on a beam bed sheep through the beams also a lower limiting surface. Beam- the bed consists of a frame of strong beams, the length of which on the frame can be 5-10 meters and the width 1-2 m. This can well fi as depending on the capacity of the lifting devices- in manufacturing (trucks or traverses). inside the frame beams run at equal distances, ie parallel to the long side. The pipes are then placed so that the beams will form the underside of the mold. The invention now provides an order in which the pipes are attached and aligned so that the linearity of the pipes is at least as good as that of the beams. On the tubes, which have an almost circular section, sound the part of the periphery that is to form the lower part is flattened something. This flattening is done between 30 - 90 degrees of cent- rumvínkeln. In the middle of this leveling, a rail is attached, which is shaped like an upside-down T. The rail runs interrupted, however, at intervals at equal distances. These interruptions occurs, for example, once per meter to a length of 5 cm.

This can be varied within wide limits and the dimensions given here are introduced only for understanding the function. On beam- the bed between the beams is at the same distance as the broken rail, placed washers, the upper edge of which is placed edge to edge with the upper edge of the beams. The tiles are fitted with a Y-shaped recess with the opening positioned so that the leg of the T-shaped rail fits into the interior of the Y-shaped recess. The widening part of the Y- the mold is used to guide the rail, since the oil line tubes may have prevented easy insertion.

Figure 2 shows a picture of the tray, which is between the beams in order to, together with the the tubes created upside-down T-rail, answer to that the mold tubes are guided in the correct position vertically and horizontally.

In addition, it is important that good alignment is obtained between form pipes and beams, so that no concrete can drain out. This causes soiling, but also, if concrete is allowed to seep out that the concrete product obtained has a so-called "beard".

Figure 1 shows a section showing the function of the above said rail and washer with recess. Above two adjacent the parallel beams (1) have been placed a pipe (3) with flattened periphery in the lower part (ll). On this tube, the T-rail (4) can be seen, which runs along with certain interruptions the tube (3).

Figure 2 shows the tray (5) seen from above. The washer (5) is provided with the Y-shaped recess (6) divided in the interior the part (7) and the widening outer part (8).

It is, of course, of the utmost importance that the beam bed of strong beams and that a careful adjustment of the flatness is done. This entire beam bed is then placed on three or more stock trestles, which in turn are provided with vibration generating devices, all for the purpose of supplying ensure a good casting.

10 15 20 25 44-7 004 PATENT CLAIMS Device for casting elongate bodies of concrete (9) with high linearity in a form of so-called battery design, where the molds consist of pipes (3) with a substantially circular cross-section, which are placed at the top between beams (1), which within a frame run parallel to the long sides of the frame, the beams (1) form lower boundaries and two parallel tubes (3) form side boundaries of the mold, the device being characterized in that the tubes (3) change substantially circular cross-sections in the lower part so much that the distance between two beams (l) is bridged by a flat piece (ll) and provided at the bottom with a longitudinal rail (4), the cross-section of which is an upside-down T and whose running along the pipe (3) is interrupted in a number of places with equal distances, between the beams (1) fasteners (5) are fastened, which have a Y-shaped recess (6-8) and the washers (5) are fastened so that all the openings on the recesses face in the same direction in the longitudinal direction of the beams o ch are placed so that their upper surface is in the same plane as the upper surface of the beams (1) and the distance between the washers (5) shall be the same as between the breaks in the rail (4) on the pipes (3), which are then put in place between the beams (1) and the end surfaces of the rails (4) are pressed against the recesses of the washers (5), thereby forcing the rail (4) of the tube (3) into the inner part (7) of the recess, whereby a control of the tube (3) takes place in vertical and horizontal led. ._ _....-___....__._____.._.______.._ V, _-> .__ -_ _ PQOR QUALITY ':.-_- ~ _.-. »., _ - '_: Tulfm, _-_- ~~' -».: -. r. - «n. _.
