Definitions

  • the present invention relates to a method of forming a cavity in the casting of preferably parallel earth walls, said method comprising embedding and use of a sleeve which comprises an essentially tubular male part and an essentially tubular female part, wherein the outer wall of the male part has outer threads which are in engagement with corresponding inner threads of the female part, and wherein mutual rotation of the male part and the female part causes the male part to be displaced relatively to the female part .
  • the invention moreover relates to a sleeve suitable for embedding in concrete, wherein the sleeve is essentially tubular and has a variable length, wherein the ends of the sleeve are provided with means for engagement with the preferably parallel earth walls formed for the casting, and wherein the sleeve comprises an essentially tubular male part and an essentially tubular female part, wherein the female part is slidably arranged in the male part, and wherein the outer wall of the male part has outer threads which are in engagement with corresponding inner threads of the female part, and wherein mutual rotation of the male part and the female part causes the length of the sleeve to be changed.
  • the invention also relates to manufacture and use of such a sleeve.
  • US Patent 5 405 119 thus describes an adjustable sleeve where two pipes as male part and female part may be tele- scopically displaced mutually.
  • the two pipes are fixed mutually by a clamp.
  • the ends are cups which are in intimate engagement with the boards.
  • the technique is only suitable for casting where formwork is used.
  • This type of sleeve is difficult to use, because the two parts have to be pressed vigorously away from each other to create friction against the formwork while tightening the clamp. This is difficult, and therefore the sleeve will easily be a poor fit, which involves the risk that it falls off during casting.
  • the sleeve is moreover provided with a strong rubber band, which is arranged interiorly, and which is to keep the parts together during mounting. This rubber band is in the way when the sleeve is subsequently to be used, and must therefore be removed.
  • US Patent 4 079 912 describes another adjustable sleeve where the length is adapted by screwing two threaded pipes relative to each other. The distance of the forming boards is ensured by a threaded member which extends through the sleeve.
  • the technique can be used only for casting where formwork is used, and also involves several other negative aspects . Including that the holes in the formwork for the threaded member must be drilled pre- cisely for the threaded member to be passed through them. Frequently, the formwork is so large that a person cannot both hold the sleeve and simultaneously move the threaded member through it. That is that two persons are required for mounting, which is unduly expensive. After pouring " and setting of the concrete, the threaded member must be removed for the formwork to be removed. Also the internal walls must be removed. The sleeve is provided with these to invent ingress of concrete during pouring and to stabilize the threaded member.
  • a sleeve for casting both with and without a formwork is known from US Patent 4 119 293.
  • This patent concerns a sleeve which consists of a male pipe enclosed at its ends by two female pipes which are provided with outwardly facing serrations. Interiorly in the male pipe there is a strong spring mechanism which is released by the withdrawal of a release pin, whereby the spring mechanism pushes outwardly on the female pipes. This causes the fe- male pipes to be pushed out, and the serrations are pressed into the earth walls or the formwork, and the sleeve is kept in place owing to the spring force and the tip of the engagement of the serrations .
  • the technique described is vitiated by several drawbacks, including that the spring mechanism is expensive to manufacture, and particularly that it has to be removed before the sleeve can be used.
  • the spring mechanism can moreover involve risks in the manner of a fox trap, when it is com- pressed for insertion into the male pipe and again when it is to be removed. In addition, it takes a great effort to remove the female pipes in order to withdraw the spring mechanism.
  • a further drawback is that if a stone, a root of a tree or another object is encountered, then the engagement will be very poor, and the sleeve will no be a tight fit either.
  • An object of the invention is to provide a method of forming a cavity in the casting of preferably parallel earth walls, wherein the earth wall is used as a casting form, and wherein a sleeve is embedded, which breaks through the earth wall and achieves a firm engagement with it at a desired depth.
  • Another object is to provide a method which allows the sleeve to be mounted easily by one person, and which does not require that parts of the sleeve subsequently have to be removed before the sleeve is to be used.
  • the male part and/or the female part comprises a means intended to break through the surface of the earth walls for forming an engagement with it, said means being rotated so as to saw a ring-shaped hole in the earth wall.
  • This ensures that objects that might present an obstacle to the formation of the engagement are removed by the sawing, and that a free passage by way of the hole is created for the means and thereby also for the male part and/or the female part. Since the hole is ring-shaped, it is moreover ensured that the earth wall remains intact both externally and internally in the means, which stabilizes and enhances the engagement, so that the sleeve is firmly arranged and is not dislocated during the casting.
  • the male part or the female part can be rotated simultaneously with the means in such a manner that the male part and the female part are displaced, and the means is driven into the hole in the earth wall, it is ensured that the means can be driven in in step with the sawing. That is that it takes place simultaneously, so that the hole is not made deeper than necessary, which might cause the sleeve to become loose.
  • the male part and the female part may be provided with a gripper device which is used for rotating the male part relative to the female part, so that this can take place in a user-friendly manner, as it is easier to apply the necessary force.
  • Another object of the invention is to provide a sleeve suitable for embedding in concrete, wherein the sleeve is secured in parallel earth walls in such a manner that complete engagement with said earth walls is ensured, and is also easy to install, and where no parts subsequently have to be removed in order for the sleeve to be used.
  • a further object is to provide a sleeve which is inexpensive to manufacture.
  • Another novel and characteristic aspect of the invention is that the means for engagement are intended to break through the surface of the earth wall for arranging the means at a certain depth in the earth wall, and that at least one of the means is rotated so as to saw a ring- shaped hole in the earth wall into which at least the one means is simultaneously driven.
  • the means comprise teeth which taper in a direction toward the end of the sleeve.
  • the male part and the female part may be provided with a gripper device for facilitating the mutual displacement, thereby making it easier for the user to operate the sleeve.
  • the gripper device may comprise at least one collar which extends from the sleeve and outwards, and the cross-section of the collar varies with the circumference of the collar so as to provide suitable projections which are useful for gripping in connection with the rotation.
  • the gripper device has a first collar which is positioned on the female part, and the gripper device has a second collar which is arranged on the male part near the end of the sleeve so as to facili- tate rotation of both the male part and the female part.
  • the length of the sleeve can be varied.
  • the sleeve is thus arranged between earth walls, and then its length is varied and the means are pressed into the earth wall.
  • the principle of changing the length may be embodied according to the telescopic principle, where an essentially tubular female part encloses an essentially tubular male part which is slidably arranged within the female part. It has been found to be particularly expedient if the male part and the female part are in engagement with each other by a screw mechanism. By screwing the male part relative to the female part the sleeve may be extended, and at the same time the screw movement of the ends facilitates insertion of the ends into the earth wall.
  • the ends of the sleeve with means which break through the surface of the earth, so that the means may be arranged below the surface of the earth wall.
  • These means may be constructed in different ways, e.g. as threads which are screwed into the earth wall.
  • the means are formed by serrations or teeth at the end of the sleeve.
  • the teeth which taper in a direction toward the end of the sleeve serve as a saw during the rotation of the sleeve about its longitudinal axis, so that the end of the sleeve may be arranged in- side the earth wall by a screw movement.
  • Fig. 1 shows a sleeve according to the invention
  • Fig. 2 shows the female part in detail
  • Fig. 3 shows the male part in detail
  • Fig. 4 shows the sleeve used between two earth walls.
  • Figs. 1, 2 and 3 show a sleeve 1 according to one of the embodiments of the invention.
  • the sleeve 1 comprises a male part 2 which is arranged in a female part 3.
  • the male part 2 is provided with outer threads 4 which are in engagement with inner threads 5 in the female part 3. Rotation of the male part 2 relative to the female part 3 causes the length of the sleeve 1 to be changed.
  • Fig. 4 shows the sleeve 1 used between two earth walls 6, 6 ' in a trench 7 which has been dug and is to serve as a casting form for the concrete foundation.
  • the ends 8, 8' of the sleeve 1 are provided with means 9, 9', e.g. teeth as shown in figs. 1-3, for engagement with the earth wall 6, 6'.
  • the teeth 9, 9' serve as a saw during the rotation of the sleeve 1 about its longitudinal axis, whereby the ends 8, 8' of the sleeve 1 may be arranged in the earth wall 6, 6' by a screw movement.
  • the sleeve is advantageously provided with a gripper device 10, 10' at the female part 3 and the male part 2 for facilitating the mutual displacement.
  • the gripper device 10, 10' may be constructed in different ways and is preferably provided as collars 10, 10' which extend from the sleeve 1 and outwards.
  • the collar 10 of the male part is advantageously arranged in the vicinity of the end 9' of the sleeve 1. This involves two advantages. First, a long travel of the male part 2 in the fe- male part 3 is ensured hereby. Second, in case that the earth wall 6 ' in which the male part 2 is arranged is of a much softer kind than the opposite earth wall 6, the collar 10 ' will serve as a stop and prevent the male part 2 from being screwed very far into the earth wall 6' be- fore the female part 3 has been screwed sufficiently far into the opposite earth wall 6.
  • the position of the collar 10 on the female part 3 is not so decisive, but it is advantageous that the collar 10 is far away from the end 8 of the sleeve, since, otherwise, it may be difficult to grip the collar 10 during the mounting when the ends 8, 8' of the sleeve 1 have already been screwed partly into the earth wall 6, 6'.
  • the cross-section of the collars 10, 10' vary with the circumference of the collars .
  • This variation which is shown as notches 11 in the collar 10 in figs. 1-3, also has two functions.
  • the first function is to provide a better grip of the collars 10, 10'.
  • the second function is as follows: If the male part 2 has been screwed into the earth wall 6 ' so that its collar 10 ' is in engagement with the earth wall 6 ' , it is no longer possible to grip this collar 10'. Then there is the risk that rotation of the collar 10 of the female part causes rotation of the entire sleeve 1. This may happen if the earth wall 6' is of a much softer kind than the opposite earth wall 6.
  • the construction of the collar 10, 10' in the manner shown in figs. 1-3 has shown, however, that the collar 10' when engaging the surface of the earth wall 6 ' offers a very great frictional resistance, so that the male part 2 will not tend to follow the rotation.
  • This provides precisely the intended effect that rotation of the collar 10 of the female part 3 causes an extension of the sleeve 1, whereby the end 8 of the female part with the means 9 is screwed deeper into the earth wall .
  • a typical material for the manufacture of the sleeve 1 is metal or plastics. Plastics has the advantage that it is very durable, and that it can be manufactured e.g. by injection moulding in a simple and inexpensive manner.
  • the aim of the invention is to provide a sleeve 1 where both ends 8, 8' are provided with means 9, 9' for breaking through the surface of the earth wall 6, 6'. But it is within the ability of a person skilled in the art to construct a sleeve 1 where just one of the ends is provided with these means, e.g. teeth. This might be the case if the casting form for a concrete wall or a foundation is formed by an earth wall at one side, while forming boards are used at the opposite side.

Abstract

L'invention concerne un procédé destiné à former une cavité de coulage définie par des parois de sol de préférence parallèles. Ledit procédé comprend le noyage et l'utilisation d'un manchon muni d'une partie mâle essentiellement tubulaire et d'une partie femelle essentiellement tubulaire, la paroi extérieure de la partie mâle comportant des filetages extérieurs en prise avec des filetages intérieurs correspondants de la partie femelle. La rotation réciproque de la partie mâle et de la partie femelle amène la partie mâle à se déplacer par rapport à la partie femelle. L'invention se caractérise, entre autres, en ce que la partie mâle et/ou la partie femelle comprend un organe à dents de scie destiné à traverser la surface d'une paroi en vue d'entrer en prise avec celle-ci, ledit organe tournant de manière à ménager un orifice annulaire dans la paroi. L'invention se rapporte en outre à un manchon destiné à être noyé dans du béton et présentant une forme essentiellement tubulaire ainsi qu'une longueur variable. Les extrémités de ce manchon sont pourvues d'un organe destiné à entrer en prise avec les parois parallèles formées en vue d'un coulage, ledit organe permettant de traverser la surface d'une paroi de sol en vue de la mise en place du manchon à une profondeur donnée entre ces parois de sol.
