Definitions
- the present invention relates to a bottom ring for a mould for casting a concrete pipe, which bottom ring is adapted to form an end face of the concrete pipe.
- Background Art DE 202 16 186 Ul shows in Fig. 6 a concrete pipe, which has an end face and is arranged to be assembled with another concrete pipe provided with an end face, with intermediate load-distributing strips which have a first portion embedded in the concrete pipe, and a second portion projecting from the end face of the concrete pipe.
- the load-distributing strips here consist of sand-filled plastic tubes.
- the object of the present invention is to provide a simple bottom ring for a mould intended for casting a concrete pipe provided with partially embedded load- distributing strips, especially a bottom ring of this type, which in a very simple way can be manufactured by modifying an existing bottom ring for a mould intended for casting a concrete pipe without partially embedded load-distributing strips.
- a bottom ring which is of the type stated by way of introduction and characterised in that it has at least two through slots which extend in the circumferential direction of the ring and are distributed in the circum- ferential direction and hold rubber strips for partial embedding in the concrete pipe during casting of the concrete pipe, said slots having a smaller width than a first portion of the rubber strips, which is adapted to be embedded in the concrete pipe, and a greater width than a second portion thereof, which is adapted to project from the concrete pipe, the bottom ring holding the rubber strips suspended from the slots.
- the rubber strips have between their first portion and second portion two opposite shoulder portions, by means of which the rubber strips are suspended from the slots.
- Fig. 1 is a vertical sectional view and shows a portion of a concrete pipe provided with a partially e bed- ded rubber strip.
- Fig. 2 is a top plan view and shows a bottom ring according to the invention intended for a mould for casting the concrete pipe according to Fig. 1.
- Fig. 3 is an enlarged sectional view taken along line III-III in Fig.
- Fig. 4 is a top plan view and shows an alternative embodiment of a bottom ring according to the invention.
- Fig. 5 corresponds to Fig. 1 but shows the concrete pipe with the rubber strip embedded in a different position.
- Fig. 6 corresponds to Fig. 2 but shows a bottom ring according to the invention intended for a mould for casting the concrete pipe according to Fig. 5.
- Fig. 7 is an enlarged sectional view taken along line VII-VII in Fig. 6 and shows the bottom ring with a rubber strip arranged therein. Description of Preferred Embodiments Fig.
- FIG. 1 shows an end portion of a concrete pipe 2 provided with a socket end 1 and an opposite end portion of a concrete pipe 4 provided with a spigot end 3.
- the two concrete pipes 2 and 4 are to be assembled end face to end face with an intermediate load-distributing means, which here consists of three circular-arc-shaped rubber strips 5.
- the three circular-arc-shaped load-distributing strips 5 are partially embedded in the concrete pipe 2 and are uniformly distributed in the circumferential direction thereof.
- Each of the strips 5 has in the shown example an extent of about 60°.
- Each strip 5 has a first portion 5' embedded in the concrete pipe 2, and a second portion 5" projecting essentially axially from the radially inner end face 6 of the concrete pipe 2.
- the first portion 5' is made of a vulcanised rubber material with a hardness of 35-70 IRHD.
- the second portion 5" which has a cross-section tapering away from the first portion 5', consists of a softer core of unvulcanised rubber material, which is externally enclosed by a layer of vulcanised rubber material.
- a mould which comprises a bottom ring 8 according to the invention.
- a bottom ring 8 is shown in Figs 2 and 3, the bottom ring 8 in Fig. 3 being shown with a rubber strip 5 arranged therein.
- the bottom ring 8 is circular and has a horizontal inner annular part 8' and a horizontal outer annular part 8", which are connected to each other by means of a vertical annular frame part 8'".
- a rubber strip 5 is placed in each slot 9. As shown in Fig.
- the strip 5 has between its first portion 5' and second portion 5" on each side a shoulder portion 10, by means of which the strip 5 is suspended from the bottom ring 8 in the slot 9 in such a manner that its first portion 5' is located above the inner annular part 8 ' of the bottom ring 8 and therefore will be embedded in the concrete pipe 2.
- Fig. 4 shows an alternative embodiment of a bottom ring 11 according to the invention. The bottom ring 11 differs from the bottom ring 8 according to Fig.
- the slots 12 and 13 on the two circles are slightly offset relative to each other in the circumferential direction.
- the slots 12 on the inner circle are located opposite to the corresponding slots 13 on the outer circle.
- FIG. 5 shows the concrete pipe 2 with the load- distributing means consisting of the three strips 5 arranged in such a manner that the first portion 5 ' of the respective strips 5 is embedded in the concrete pipe 2, and the second portion 5" thereof projects essentially axially from the radially outer end face 14 of the concrete pipe 2 to be pressed against the radially outer end face 15 of the concrete pipe 4.
- the bottom ring 16 shown in Figs 6 and 7 differs from the bottom ring 8 shown in Figs 2 and 3 only by the slots 9 being formed in the outer annular part 8" of the bottom ring 16, not in the inner annular part 8' thereof, and the bottom ring 16 having an annular flange 17 which projects from the underside of the outer annular part 8" and by means of which the bottom ring 16 can be placed on a base in such a manner that the outer annular part 8" is held at a sufficient distance from this base to make room for the projecting second portion 5" of the rubber strip 5.
- the rubber strip 5 has at the level of the slot 9 a slightly smaller width than the slot.
- a bottom ring 8, 11 or 16 can be manufactured in an extremely simple way by modifying an existing bottom ring for a mould intended for casting a concrete pipe without partially embedded load-distributing strips simply by the slots 9 or 12 and 13 being formed in the existing bottom ring. No further modifications or corrections of the bot- torn ring need be made.
