Definitions
- the invention relates to a device for Coupling the proximal end with external thread a screw injection anchor to an also with external thread provided end of an extension tube, which Device contains a coupling sleeve, the ends of which corresponding internal thread are provided.
- Screw injection anchors are one Pipe or a hollow rod, at least at the distal end is provided with a screw wing and that (which) is rotated into the ground. While and / or after the anchor has been driven in by the Hydraulic cavity of the pipe or rod Mortar introduced by the existing in the pipe wall Holes in the between the screw wing turns enclosed soil mass is injected with the purpose to solidify this soil mass.
- Such screw injection anchors are large Scale for anchoring floor-supporting and / or water-retaining structures, for ground anchoring against "Exposure” to be secured concrete buildings and the like used.
- the coupling bush described at the beginning is a known, simple, cheap and effective means of Connect the actual anchor body with an extension tube and also for the mutual coupling of Extension tubes.
- the latter is e.g. a problem if it is to prevent the "floating" of concrete structures, such as concrete soles to be installed under the ground level.
- concrete structures such as concrete soles to be installed under the ground level.
- one must be from the top of the earth driven anchor to the depth of the anchor Concrete plant are abbreviated before excavation the construction pit required for the manufacture of the concrete plant. This is usually the last of each anchor inserted extension tube removed.
- the invention now intends for such cases to offer a cheap and effective solution without sacrificing the Impact effectiveness in driving.
- this purpose is achieved with a Generic device, which is characterized is that the coupling bush with a second coupling bush works together, one half of which first coupling bush is similar and the second half is expanded and executed in such a way that it is sealing fits over an end part of the first coupling bush, the extended coupling bushing half with at least a bayonet slot starting from the front edge of the same is provided, which with a at a point between the ends of the first coupling bush radially outwards protruding spigot works together.
- the coupling device proposed according to the invention is actually a combination of two Coupling bushings.
- One coupling socket remains in use, which corresponds approximately to the usual coupling bush, sitting in the floor as a lost part, just like this applies to the traditional socket, while the second Coupling socket with its extended and with a bayonet slot provided end under the circumstances for which the device according to the invention is recovered and can therefore be used several times.
- 1 is known per se Designated tie rod, consisting of a tube 2 with a at the distal end of the same screw wing body 3 and one that closes the hollow tube at the distal end Centerpiece 4.
- the anchor tube 2 is with a first extension tube 5 by means of an internal thread Coupling socket 6 of conventional type coupled.
- anchor tube 2 and extension tube 5 on their ends to be joined together with corresponding external thread Mistake.
- a and B are the two composing parts referred to the coupling device according to the invention, with the help of which the extension tube 5 with a second Extension tube 7 can be coupled.
- This second extension tube is sufficient after the anchor 1 to the desired Has been driven up to above the depth top edge of the earth not shown in the drawing.
- the second extension tube should then, if necessary after injecting a hydraulic mortar over the Hollow core of the anchor and the extension tubes, loosened and be taken out to be able to dig out a construction pit, the bottom of which is designated 8.
- part A of the coupling device On the top or proximal end of the first extension tube, which is also provided with an external thread, sits part A of the coupling device according to the invention.
- Part A is made from a similar coupling bush 6a formed like the coupling bush 6.
- the socket 6a is however, approximately in the middle between the socket ends two diametrically opposed holes, through which holes a pin 9 is punched the ends of which are radial on both sides of the bush 6a protrude.
- Part B of the coupling device according to the invention contains a socket 6b, which correspond to the socket 6 can and on the lower or distal end of the second Extension tube 2 screwed sits.
- a socket 6b On the socket 6b another bushing 10 is attached by welding, which is sealed by an O-ring 11 on the upper End part of the socket 6a fits.
- the further socket 10 is with two diametrically opposite one another Bayonet slots 12 provided on bayonet locks known way with the two sides projecting ends of the pin 9 can work together.
- the socket 6a of part A remains as before a socket 6, as a permanent or lost part the top end of the first extension tube.
- the pin 9 can be used to connect the armature and contribute to the construction to be anchored.
- Part B is with the second extension tube 7 with removed and is therefore, so to speak, for reuse "regained".
- the coupling device is largely made up of existing parts is assembled, such as the two sockets 6a and 6b, which only one extended Socket piece and a pin must be assigned. It it will be clear that the two sockets 6a and 6b dispenses with the attachment of threads at one end can be.
