Definitions

  • the invention relates to a spreading strut for forming a Sp Dreckhornens for shoring devices according to the preamble of claim 1 and with this spreading strut formed Sp Schwarzrahmen and shoring devices which have such Sp Schwarzrahmen.
  • Grabenverbauvoriquesen usually have shoring, which consist of two opposing, large-scale Verbauplatten, which support the trench walls. Such bogies can either be installed individually or strung together. In adjoining shingles the edges of the shoring are usually performed in opposing columns. Between the supports bending rigid expansion frame are arranged in height displaceable. For this purpose, the supports have horizontally extending linear guides.
  • the supports with the vertical linear guides are usually integrated in the shoring panels. On each side edge of a Verbauplatte such a linear guide is arranged.
  • the expansion frames are based on several, a vertical distance from each other having support points relative to the linear guides.
  • the support points are usually formed by rollers.
  • a shoring device with edge-guided shoring panels is for example from the European patent EP 0 619 853 B1 known.
  • the Sp lanternrahmen two mutually parallel struts. These struts are connected by vertically extending and at different heights on the linear guide supporting carriage with each other. On each side of the Sp Schwarzrahmens a carriage between an upper and lower Sp Schwarzstrebe is arranged.
  • Sp Drettillhornen which have the shape of an inverted U.
  • the two lateral legs of the inverted U are formed by the two carriages.
  • At the upper end of each carriage one end of the expansion strut is flanged.
  • Such a Sp Schwarzrahmen allows a greater installation height of internals, especially pipes, which are installed in the channel, which is supported by the shoring device.
  • the object of the invention is to develop a simple and inexpensive Verbauvorraum such that below a Sp Drhyroids a larger installation space remains.
  • a connecting strut is attached to the ends of the spreading strut, which extends transversely to the spreading strut and is arranged at the lower end of one of the fastening elements.
  • the fastening elements are arranged at the ends of the expansion strut, in each case with the interposition of a connecting strut extending transversely to the expansion strut.
  • connection strut extends vertically, wherein the expansion strut extends horizontally.
  • the guide member which is usually formed by the carriage, is arranged in a predetermined by the position of the linear guide height. Since the expansion strut now no longer extends directly between the guide members, but offset upwards between the attached to the guide links connecting struts, the clear space below the expansion strut can be significantly increased.
  • the spreading strut can be raised, for example, by 1 meter.
  • the connecting struts can simply be removed from the ends of the spreading strut and the guide members can be flanged directly to the end of the spreading strut.
  • the system according to the invention is therefore extremely variable. It can be carried out either with direct attachment of the guide members at the ends of the spreader strut with normal passage height or when using the connection struts with increased passage height.
  • the expansion strut and the connecting strut are usually made of metal profiles, usually made of steel.
  • the ends of the expansion strut are bolted or welded to the connecting struts.
  • the screw allows variable conversion of the expansion strut according to the invention by removing the connecting struts.
  • the fastener may be on the connecting strut a flange plate with through holes for connecting screws.
  • the holding element of the guide member may be formed by a complementary flange plate.
  • the Spstrestrebenende may have a flange plate which is formed corresponding to that on the connecting strut. So the spreading strut can firstly directly and secondly under embglagung the connection bars according to the invention are screwed to the guide element.
  • an additional fastening element can be arranged at the upper end of the connecting strut. For example, if additional sheathing panels must be placed to realize a deeper trench, a head portion can be attached to the additional fastener which holds the additional shoring panels.
  • the invention relates to a spreader frame with two guide members, which are connectable to the sliding guide in each case with a linear guide a Verbauvorraum, and with a spreading strut described above.
  • a connecting strut is attached to each end of the spreading strut, which extends transversely to the spreading strut and at the lower end of which one of the fastening elements is arranged.
  • Fasteners and retaining elements consist - as mentioned - preferably from flange plates with matching hole patterns for passing through fastening screws.
  • the guide members of the expansion frame according to the invention are preferably formed by carriages.
  • the carriages have vertically spaced-apart rollers, which are intended to unroll on a guide surface of a vertical linear guide of a shoring device.
  • the linear guides are either provided on the sides facing each other by separate supports, which respectively support the edges of Verbauplatten, or integrated into the Verbauplatten.
  • the guide member may have a retaining body which engages positively in a guide channel of the linear guide. This retaining body transmits tensile forces on the expansion frame and prevents tilting of the lining plate, in which the lower end of the lining plate is pushed towards the trench center.
  • the lower end of the connecting strut is secured to the upper end of the guide member to allow an optimal increase in the space below the expansion strut. This extends the Connecting strut from the guide member from vertically upwards.
  • the above-mentioned additional fastener at the upper end of the connection strut can cooperate with an additional holding element, which is arranged on a head part.
  • the headboard can be inserted in an additional linear guide.
  • the additional linear guide can be arranged in practice on an additional Verbauplatte, which serves to increase the Verbaufeldes.
  • the invention relates to a shoring device with two opposite, large-scale Verbauplatten on which vertical linear guides are arranged.
  • a spreader frame of the type described above is inserted between two mutually opposite linear guides.
  • the linear guides are preferably formed by supports connected to the lining plate.
  • a support can either receive and support a vertical edge of the lining plate or be fixedly connected to a vertical edge of the lining plate.
  • an additional lining plate can be plugged onto the opposite lining plates, which each have an additional linear guide, in which one of the head parts is guided displaceably.
  • the head part which is arranged at the upper end of the connecting strut, thus supports the additional Verbauplatte and fixes them vertically above the lower Verbauplatte and aligned with this.
  • the in the Fig. 1 Shoring device shown consists of two large Verbauplatten 1,2, which are arranged opposite one another and serve to support the walls of a trench. At the vertical edges of Verbauplatten 1,2 vertical supports 3,4,5,6 are arranged. The supports 3 - 6 are firmly connected to the Verbauplatten 1,2 in the illustrated embodiment. In alternative embodiments of the invention (not shown), the supports are formed separately and have guide channels in which the edges of the Verbauplatten can be supported.
  • Each support 3-6 has a linear guide 7-10 in its upper region.
  • the linear guides 7-10 have two mutually parallel guide webs 11,12, which form guide surfaces and between which a guide channel is formed.
  • On the guide surfaces roll rollers in a known manner.
  • In the guide channel engages a retaining body in a known manner.
  • the rollers and the retaining body are each arranged on a carriage 13-16, which forms a lateral guide member for the Sp Schwarzrahmen and in conjunction with Fig. 6 will be described below.
  • the in the Fig. 1 and 2 shown shoring device has two identical Sp Schwarzrahmen 17 and 18.
  • Each expansion frame 17 and 18 has a two-part expansion strut 19 and 20, respectively.
  • a connecting strut 21-24 is attached at the two ends of each spreading strut 19,20 .
  • the ends of the spreading struts 19, 20 have flange plates which are screwed to wall sections of the connecting struts 21-24.
  • One of the outer wall of the connecting strut 22nd (please refer Fig. 3 ) formed in the lower region flange plate 35 forms the arranged at the end of the expansion strut 19 fastener and is bolted to a complementary flange 36 at the upper end of the carriage 14.
  • connection struts 21-24 By the vertically extending connection struts 21-24 ( Fig. 1 ), the clear height below the expansion strut 19,20 is significantly increased. If such a large clearance height is not required, the connecting struts 21-24 can be removed between the ends of the spreading struts 19,20 and the carriage 13-16 and the carriages 13-16 are screwed directly to the ends of the spreading strut 19, 20.
  • the device according to the invention is additionally advantageous for larger installation depths.
  • the upper, facing the trench wall portion of the outer wall of the connecting strut 22 forms a flange plate 37, which forms an additional fastening means.
  • the additional attachment means 37 cooperates with an additional holding means 38 of the head part 26.
  • This additional holding means 38 is formed by a flange plate 38 arranged on the head part 26, which lies on the side of the head part 26 facing towards the trench center. All flange plates 35-38 are preferably formed by steel plates, which are part of the steel profiles that make up the respective components.
  • the head part 25,26 serves to stabilize additional Verbauplatten 27,28, which are attached to the upper edge of the lower Verbauplatten 1,2.
  • the additional Verbauplatten 27,28 have additional linear guides 29,30, which are supported against the head parts 25,26 and are also engaged behind this.
