Definitions
- a trench shoring unit of this type is known from DE-OS 25 02 567.
- the connection between the steel plates and the legs of the U-profiles is based on spot welding.
- trench shoring units of this type have a relatively high weight, the production proves to be very complex and time-consuming.
- the object of the invention is to remedy this and to provide a trench shoring unit which is significantly reduced in its own weight, but on the other hand has quite comparable stability values and, moreover, is easier to manufacture.
- the legs of the U-profile have mounting holes for the strut pins.
- the struts it proves to be advantageous for the struts to engage, with an intermediate layer, over the parting line of two adjoining coupling strips, which overlap the flanges, are designed as an H-profile and, on the other hand, are overlapped by the strut shoe.
- Such a configuration enables individual trench shoring units to be added to a higher-level unit; For example, if you want to switch from hem lining to full lining.
- the trench shoring unit E which can preferably be used as a lightweight shoring system for gas and water pipes, consists of two mutually congruent walls W, which are held together by means of end struts 1 and, if necessary, tension cables, chains or the like arranged diagonally in space.
- the unit E hangs on a pulling harness Z for insertion and removal.
- Each of the walls W is composed of several identical partial walls 2 arranged one above the other. These are preferably cuts to length of a flat, extruded aluminum box profile.
- the cross section results particularly clearly from FIG. 6.
- There the parallel profile walls are connected to one another via support webs 3 running inside the box. The latter are shaped at the same time.
- the chambering is such that cavities H of approximately the same size are vertically adjacent to one another.
- short longitudinal ribs 4 which are directed towards one another on the inside of the profile walls, also act to reinforce the wall.
- the longitudinal edges of the partial walls 2 form a groove 5 on one side and a tongue 6 on the other side. 5 and 6 thus bring the upper and lower ends of the respective cavities H.
- Their cross section is roof-shaped with a roof apex line lying in the longitudinal center plane x-x.
- the thickness of the webs forming the groove 5 or tongue 6 corresponds to the thickness of the support webs 3 and that of the profile walls.
- the roof slopes that form the groove 5 and the tongue 6 extend as far as the inner surfaces 7 of the profile walls hollow part walls 2. Then they form a horizontally extending support shoulder 9 reaching to the outer surfaces 8 of the profile walls.
- the support shoulders extend over the entire length of the part walls 2. Due to the orientation of the support shoulders 9 perpendicular to the longitudinal center plane xx, the profile wall stands on the profile wall .
- the partial walls 2 are positively immersed in depressions 10 on lateral shoe lasts 11.
- the chambering is closed like a lid. No soil and no moisture can penetrate there.
- the shoe lasts 11 are fixed by welding. On the spring side (6) they only extend to the support shoulder 9.
- the shoe lasts 11, which practically form vertical belts, have a T-shaped foot on the trench wall side.
- the one, shorter T-leg 12 delimits the recess 10 on the trench wall side; the other T-leg 13 projects beyond the T-web 14 oriented perpendicular to the trench wall in the opposite direction.
- This T-web 13, which is approximately twice as long, is stiffened by vertical ribs 15 facing away from the trench wall.
- the flanges F are formed by the legs a, b of a U-section 17.
- the legs mentioned run parallel, in the direction of extension of the T-web 14. Their ends are bent inwards, ie directed towards each other, so that basically from one C profile can be spoken.
- the U-web c forms, together with the T-web 12 of the shoe last 11 and the T-web 14, the shoe engagement space, that is to say the depression 10 for the head ends of the partial walls 2.
- the legs a, b of the U-profile 17 are equipped with fastening holes 18 for plug pins 19 of the struts 1. These holes enable the plug-in bolts 19 to be inserted in a horizontally oriented manner.
- the fastening holes 18 extend over the entire height of the shoe lasts 11. They are at the same vertical distance from one another.
- On a partial wall 2 there are about three mounting holes 18 each.
- the socket pins 19 are each secured by means of a split pin 20 against withdrawal. The end of the plug pin 19 opposite this securing zone forms a gripping handle 21 which projects beyond the general cross section of the plug pin 19.
- Both ends of the strut 1 have a strut shoe 22. It is formed by a U-shaped profile section, the web of which is firmly connected to the threaded part of the strut end 1 ⁇ .
- the strut shoe 22 overlaps the U-legs a and b of the flanges F.
- the U-legs of the strut shoe 22 have openings 22 ⁇ lying congruent with the fastening holes 18.
- a plurality of trench shoring units E can be combined to form a superordinate unit, so that the trench walls can be supported up to the level of the base 23.
- the cross section of these coupling strips 25 results from FIG. 8. They are assigned to the U-profile 17 in a manner that overlaps.
- These coupling strips are H-profiles.
- the H-bridge divides two U-rooms open in the opposite direction. While the U-legs 26 facing the trench wall cover the U-profile 17 of the shoe lasts 11 on the outside, the U-legs 27 of the coupling bar 25 running in the opposite direction protrude into the U-space of the strut shoe 22.
- the U-legs 27 jump back by the amount of a leg thickness in relation to the legs 26, so that one and the same shoe size can be used.
- the legs a, b run in alignment with the respective U-leg 27.
- the plug holes of the coupling bar 25 have a diameter which corresponds to that of the row of holes in the shoe lasts 11.
- the holes in the U-legs 27 are placed so that the shoe can not be arranged at the level of the joint 24 between two walls W, but only in the area of these walls.
