The invention relates to a tensioning device for shoring machine-dug line trenches or comparing by means of shoring panels and arranged on it! iiderlagarn for receiving the shoe · ha that can be supported horizontally against the shoring panels and central ice Spindle drive longitudinally adjustable tendon arm,

A bsßannte jig aestsht from i to each other / erbindbarei Rohrabschnittsn, of which the respective outer tube sections are ausgabildst as (flutter for receiving a Gemindespindel whose äußecss LimSwitch- carries sinen Klotz _t which are held in a U-profile posts sindf dio in turn fixedly attached to the Versauplatten »The block is firmly connected to the assigned post by means of bolts,

The invention is seen in the fact that the abutments are steel posts with slotted box profile. trained ', and the Tendon shoes «form-fitting over their entire length Ability to lead »With this training, the tension members can • serve as both tension and compression members. '

It is advantageous that the steel posts with the shoring « panels can be detachably connected conditionally be connected in one piece with the lining panels »This results in lower costs in the production of the lining panels»

According to a further embodiment of the invention, it is provided that jsd8S tensioning member consists of two spindles with mutually opposing threaded parts, a pipe covering the spindles with a nut part arranged in the ffiitte with opposing pipe sections and pressure housings arranged at the ends of the spindles with a larger cross-section than that soiuie tube of a shoe bastaht _t similar to a dumbbell with two sus axialsn _s by aine push rod connected slices odar blocks is formed "won which represents a block in the other block in Druekgahsuss and the steel post on a form-locking receiving sine bar!"

More details of the invention emerge from the following Description of an embodiment according to the invention based on the drawing. In this show:

Ois clamping device 1! consists , as the drawing shows, of Spanngiiodern 4 _; this in turn from kiubx spindles 5 _p ß with opposing thread parts 7j8. a tube 9 covering the spindles 5 ₅ 6 with opposing geiaind sections 10, 11 arranged in its width and arranged at the ends of the spindles 5 _P 6

Printing houses 12 stand by. The Oruckgahäuses 12 u / iron big one »compared to the fiohr 5 larger cross-section and have a box-shaped, obsnly open professional pressure housing serves to accommodate a shoe 13, which is similar to a dumbbell made of ziL'si with an axial distance and through Aine kuvza push rod (Fig. 3) rigidly connected to each other with blocks 15, 16 or discs. Each block 16 is introduced into the pressure vessel through an opening 17 on the side and is protected against filling dirt.

In order to tension the verbatj plates 2, at least two brackets are usually required. As shown in Fig. 1, they can be aiasckuiiSig, as shown in FIG.

can be pulled out of the trench.

The tendons 4 can, which is known per se, “in a uniform Length to be made. In limited IfIaBe can be the length of the tendon 4 by twisting the tube 9 and change the spindle 5,6 accordingly,

To further lengthen the Spsnngliedes additional 4 l / he "length guide elements 21 are provided ,, Bai the known Spanngliedem passed such Vsrlä'ngerungselemente from flanged Rohrstücksn, which attached by means of screws on the tubular body of the clamping member iuurden _o In practice, it ermiss to jsdoch always tuisdsr as . disadvantageous that the screws required for this static or were lost.

The erfindungsgsmäße Uerlängerungselement21 is, wis Figure 3 2eigt _{o f} other hand, from a block 22, which has the same dimensions laie the jig 16 of the shoe 13 has, a pressurized gas häuss 23 is dsm pressure housing 12 and a Zuüschenverbindurig 24 ,, the entwe'dsr as .shown as a rigid bolt bztu. can also be designed as a tube or as a further tension member with adjustable spindles.

The extension element brauefit; thus only to be inserted with its block 22 in the pressure housing II of the tensioning element 4 in order to lengthen it . Several elongation elements 21 can also be connected to one another in the same direction

u / arrierio If necessary, they can also be secured by bolts or other locking devices that can be attached in a suitable manner

In any case, no screws are used to elongate the tendon * it is rather a plug-in connection «

In the pressure housing 23 can then be shown in a known manner Insert shoe 13 "

In operation, two tendons 4 are inserted into the steel posts 3 which are adjacent to the building platform 2 or part of the same, and at the required height? For example, by means of retaining bolts on 25, the tube 9 _S, which is provided with corresponding attack bolts 26, is then rotated _{5 for} as long; until the tendons 4 exert the required compressive stress on the Usrbaupiatten 3.
