Definitions
- the invention relates to a trench shoring device (shoring box) consisting of a basic box of shoring panels, which is kept at a distance by spreading elements, the top edge of which has a stump edge which is relatively stable against impacts from an excavator shovel, in particular a square pressure spar, and a cutting edge on the bottom edge of each shoring panel to drive the basic box down into the ground, and with at least one level of shoring plates of an additional box arranged in alignment on the basic box.
- a trench shoring device consisting of a basic box of shoring panels, which is kept at a distance by spreading elements, the top edge of which has a stump edge which is relatively stable against impacts from an excavator shovel, in particular a square pressure spar, and a cutting edge on the bottom edge of each shoring panel to drive the basic box down into the ground, and with at least one level of shoring plates of an additional box arranged in alignment on the basic box.
- DE 20 57 263 C3 describes a device for supporting trench walls with at least two supporting walls consisting of wall sections arranged one above the other.
- the walls are kept at a distance with the help of cross struts.
- the lowest pair of supporting walls (simplified: "basic box”) has a cutting edge to be driven into the ground at the lower edge, while the upper edge of the plate opposite the cutting edge acts as a stump edge, e.g. is designed as a four-bar spar.
- the stacking boxes consisting of pairs of plates, which are to be arranged essentially vertically flush on floors above the basic box of plates, have a blunt (straight or slightly curved) end profile or the aforementioned stump edge, that is to say no cutting edge, both on the upper edge and on the lower edge.
- the shoring plates of the extension boxes differ from the shoring plates of the basic boxes essentially only in that a cutting edge is present or not.
- the cutting edge enables the basic box to be pressed into the ground.
- the top box does not need this cutting edge, since it lies on the basic box, which has already cut the soil to the width of the trench.
- the main disadvantage of using special stacking elements or boxes is that they are only used for stacking, that is to say only in the case of relatively deep trenches.
- the basic box on the other hand, is always required.
- the top box is only in rare cases, but then at least one top box is needed for each basic box. If the building contractor wants to be ready to be able to fulfill orders flexibly, he has to keep almost as many top-up boxes as basic boxes in his warehouse, even though the top-up boxes do even at normal trench depths are not needed.
- the invention has for its object to provide a trench shoring device that can do without the stacking box, which is to be described as rather uneconomical according to the foregoing, even if the height of the basic box is not sufficient to block the respective trench due to the required trench depth.
- the solution according to the invention for the trench shoring device with at least one floor of stacked elements on a basic box is that the ⁇ ufstockele duck of the shoring panels as well as the shoring panels of the basic box are designed.
- Coupling means such as protective rails and / or screw connections, are preferably provided on the butting line of cladding panels, which preclude sliding against one another when driving in and, if appropriate, separation during the dismantling of the cladding panels.
- the trench shoring device therefore essentially consists only of the basic boxes with shoring plates, which have a cutting edge suitable for driving into the ground on one longitudinal edge.
- the basic box When excavating a trench, the basic box is first driven into the ground with the cutting edge downward. An extension box is then placed on the basic box.
- the stacking box can alternatively be positioned with the cutting edge up and the cutting edge down.
- the cutting edge of the extension box and the upper edge of the basic box should be connected using a protective rail, i.e. a coupling element, which protects the cutting edge and prevents the cutting edge from slipping off the upper edge of the basic box.
- the extension box with its blunt end edge rests on the likewise blunt end edge of the shoring plates of the basic box, bolted or screwed, possibly one-side welded, connecting lugs are sufficient as a coupling element between the basic box and the mounting box which prevent the stock box from slipping and which are of particular importance when dismantling, ie when pulling the boxes out of the ground (after the trench has been completed).
- a protective rail is applied to a pair of shoring panels which are arranged one above the other with a cutting edge and which is to be made up essentially of a (preferably pressure beam-like) edge profile which, starting from one of its surfaces, adjusts itself along the length of the profile has recess extending into the profile body, into which the cutting edge is to be inserted approximately in a form-fitting manner.
- a protective rail is important in the event that an extension box is positioned with the cutting edge pointing upwards, because the box is generally pressed into the ground by means of the excavator shovel provided for excavating the trench. If one were to act directly on the cutting edge with the excavator shovel, bending of the cutting edge would be unavoidable. It is therefore important to provide a protective rail on each cutting edge for a sheeting to be closed with a cutting edge.
- the protective rail should preferably extend over the entire length of the respective plate or cutting edge. However, in individual cases, e.g. For reasons of economy, it may be advisable to position a shorter protective rail only where the excavator blade presses or even hits the plate.
- the entire length of the protective rail provided according to the invention should have a recess into which the cutting edge is to be inserted essentially in a form-fitting manner.
- this means that the recess can be formed continuously like the nut shape of the cutting end of a base plate.
- the shape of the hat should optionally extend over the entire length of the protective rail.
- the part of the nut shape which is form-fittingly adapted to the cutting edge can have interruptions along the length of the rail if the interruptions do not impair the stability and the fixed position of the rail on the cutting edge.
- the cutting edge consists of a one-sided bevel, which is to be used when using the inner side of the trench, of the respective plate edge, it is sufficient for a complete recess on the opposite side of the plate opposite the cutting edge, at sufficient intervals, in individual tabs of the protective rail to spread over the cutting edge.
- the protective rail in the narrower sense is placed on the upper edges of the ten of a shoring box if the cutting edges of the uppermost stacking box are on a two- or multi-story shoring box.
- the rear side or top side of the edge profile of the protective rail which is opposite the recess which the cutting edge is to receive in a form-fitting manner, should preferably be approximately as blunt as the opposite edge of the shoring plate. Since in this case the protective rail is machined directly with the excavator shovel when the shoring box is driven into the ground, it must be so stable that it itself (and specifically not the cutting edge underneath) is bent or otherwise damaged by the excavator shovel can.
- a rail that overlaps the cutting edge in a form-fitting manner over its entire length can be made relatively thin in the anvil part, on which the excavator shovel directly impinges, so that the thickness of the anvil part is small compared to the expansion of the rail in the direction of the adjacent plate plane.
- This ratio can preferably be in the range between values of 1: 5 to 1:15.
- a protective rail or coupling element at the transition from one another
- the protective rail should preclude a direct mutual contact of shoring plates placed one on top of the other by means of a compensation plate (e.g. in one piece) lying between the butt lines.
- a protective rail extending over the entire length of the two plates is also preferably provided, although it may also be sufficient to support only individual parts with one or more partial protective rails against one another.
- the protective rails designed as clamps are, according to further inventions Not only designed for mutually supporting the sheeting plates, but they should preferably also include connection elements which, when dismantled, allow the box located below, together with an overlying box, to be pulled out of the trench by gripping the upper box.
- the protective rails or clamps which formally overlap the cutting edges or die edges, preferably with the aid of bores leading through the cutting edges or plates, are to be firmly connected to the respective plate edge or cutting edge.
- the invention creates a modular system which consists only of base plates or base boxes and coupling elements (e.g. protective rails).
- the conventionally required extension plates, which apart from the cutting edge are practically identical to the base plates, are completely unnecessary.
- the building contractor therefore only needs the usual base plates in his warehouse and, in the event that a pair of base plates is not sufficient for a trench depth, only the coupling elements additionally.
- a decisive advantage of the invention also consists in the fact that in the case of a shoring with a basic box and a single extension box, the latter is to be arranged with the cutting edge facing upwards and the cutting edge is perfectly sealed against the damaging effects of the excavator shovel with the aid of the protective rail positively resting on the rail is secure.
