Definitions
- the invention relates to an expansion frame for sheeting panels according to the preamble of claim 1.
- Spreading frames of this type are known from the patent specification DE 22 57 881.
- the supports of the known spreading frames have two walls running at a distance from one another at right angles to the trench, between which the end regions of the spreaders are pivotably mounted and small angles.
- the end regions of the spreaders have cylindrical stub axles on both sides, some of which are supported in bearing shells which are fastened to the inner sides of the support walls.
- the bearing shells of the known spreading frames are open to the trench when the ner construction device is used as intended, so that the lateral surfaces of the cylindrical stub axles facing the shoring plates are accommodated in the bearing shells.
- the bearing eyes for the stub axles are formed by the bearing shells and by cylindrically curved ends of leaf springs which press the stub axles into the bearing shells.
- the leaf springs are preloaded into the supports in such a way that they stabilize the vertical position of the supports and the horizontal position of the spreaders.
- the supports of the expansion frame are firmly connected to the shoring panels in the longitudinal center of the shoring panels, so that a so-called center-supported shoring unit is created.
- the spreading frames can also be arranged on the two lateral ends of the shoring panels to form edge-supported ner building units.
- the spreading frames can also be independent devices if the supports have guide channels on both sides, in which the lateral edges of the shoring panels are slidably guided.
- the object of the invention is to provide a spreading frame for sheeting panels which can be taken apart and assembled with little assembly effort.
- the two supports of the expansion frame or the two shoring panels of a shoring unit, the shoring panels of which are connected to a shoring unit via at least one expansion frame should be easily separated from one another so that the expansion frames or shoring units take up less space during storage and transport.
- one end of the lower and the upper struts can be lifted out of the bearing shells of this support, so that the supports of the expansion frame are separated from one another.
- the supports of the expansion frame and the shoring plates of the shoring units connected to the supports can be transported in a space-saving manner or stored.
- the spreaders can remain attached to a support of the spreading frame. So that the spreaders can be folded down by 80 ° or 90 °, any stabilizers attached to the respective supports must also be loosened between the support and the spreaders.
- the end regions of the struts are mounted between two walls of one of the supports, and the bearing shells are fastened to the mutually facing inner sides of said walls.
- the securing parts are expediently bolts which can be inserted into bores made above the bearing shells and above the end regions of the struts in the walls of the supports.
- the stabilizers can also be fastened to the supports of the expansion frame by means of such plug bolts.
- the bearing shells for receiving the stub axles of the lower struts, which absorb compressive forces have a hollow cylindrical region whose diameter - with little play - corresponds to the cylinder diameter of the stub axles.
- the hollow cylindrical area can extend at least from the lowest point on the outside of the bearing eye to over half the height of the axle stub. It thus forms a bowl-shaped area for absorbing the compressive forces which act on the outside of the bearing eye, that is to say from the center of a spreader towards the free end thereof.
- the bearing shells for receiving the stub axles of the upper struts, which absorb tensile forces have a hollow cylindrical region, the diameter of which - with little play - corresponds to the cylinder diameter of the stub axles.
- the hollow cylindrical area can extend at least from the lowest point of the bearing eye on the inside of the bearing eye to over half the height of the axle stub. It thus forms a bowl-shaped area for absorbing the tensile forces which act towards the inside of the bearing eye, that is to say towards the center of a strut.
- Each hollow cylindrical region of the bearing eyes can extend over an angular range from 100 ° to 180 °, preferably 120 ° to 140 °, in order to absorb the forces safely.
- Stabilizers can be articulated between the end regions of the spreaders and the supports, the stabilizers being articulated to the supports by means of plug bolts.
- the assembly of a spreader frame is then carried out in a simple manner exclusively by inserting plug-in bolts into the holes provided on the supports.
- the end regions of the spreaders can be formed by spreading parts provided with an internal thread, into which spreading parts provided with an external thread can be screwed.
- the length of the struts can be varied and the dimensions of the spreader frame can be adapted to the respective requirements.
- Fig. 1 is a sectional view of an expansion frame according to the invention.
- FIG. 2 is a front view of a support of the invention
- FIG. 3 a sectional view of the support according to FIG. 2,
- FIG. 4 a perspective view of a support and the individual parts of the expansion frame according to the invention to be fastened to this support,
- FIG. 5 a perspective view of a support with attached to it
- FIG. 6 is an enlarged view of a support member with end portions of the lower and upper struts mounted therein.
- Fig. 1 shows a shoring unit with two shoring plates 6 and 7, which are kept running distance from a spreading frame.
- the spreading frame 1 has two essentially vertical supports 2 and 3, which are kept at a distance by a lower spreader 4 and an upper spreader 5.
- the spreaders 4 and 5 are pivoted through small angles in the bearing eyes of the supports 2 and 3.
- Stabilizers 8 ensure that the spreaders 4 and 5 are at right angles to the supports 2 and 3 and the pivoting range of the spreaders 4 and 5 remains limited to 5 °.
- the stabilizers 8 consist essentially of strong springs that are only expandable or compressible by a small amount. In this way, the shoring panels can alternately be pulled out of the trench by a small amount without dismantling the shoring unit.
- the end regions 9 and 10 of the spreaders 4 and 5 are pivotally mounted via cylindrical stub axles 11 between the walls 15 and 16 of the supports 2 and 3 in bearing shells 12 and 13 which are open towards the top. These bearing shells 12 and 13 are fixed on the inside of the walls 15 and 16. So that the cylindrical stub shaft 1 1 does not slip out of the open bearing shells 12 and 13 unintentionally, easily attachable and easily removable securing parts 14 are provided which overlap the end regions 9 and 10 of the spreaders 4 and 5.
- the securing parts 14 can be screw bolts, for example, which can be screwed into the walls 15, 16.
- the securing parts 14 are advantageously bolts which are attached in the walls 15 and 16 of the supports 2 in the bearing shells 12, 13 and above the end regions 9, 10 of the spreaders 4 and 5. Bores 14 'can be inserted.
- the stabilizers 8 are also fastened with detachable bolts 20 in the supports 2 and 3. These socket pins 14 and 20 can be secured against unintentional removal by split pins or the like.
- the bearing shells 12 for receiving the stub axles 11 of the lower, pressure-transmitting struts 4 have a hollow cylindrical region 17 which - with little play - corresponds to the cylinder diameter of the stub axles 1 1 and which differs at least from the bottom Place extends over half the height of the stub shaft 1 1 on the outside of the bearing eye.
- the bearing shells 13 have a hollow cylindrical region 18 which corresponds to the cylinder diameter of the stub axle 1 1 and which is at least extends from the lowest point of the bearing eye on the inside of the bearing eye to over half the height of the stub axle 11.
- the hollow cylindrical regions 17 and 18 advantageously extend over an angular range from 100 ° to at most 180 °, preferably 120 ° to 140 °.
- This configuration of the bearing shells ensures reliable storage of the lower struts. 4 absorbing compressive forces and the upper struts 5 absorbing tensile forces.
- the spreading ends with the stub axles 11 can be lifted out of the bearing shells 12, 13. So that the spreaders 4 and 5 attached to the other support 3 of the expansion frame can fold down, the stabilizers 8 are to be released there by pulling out the plug bolts 20.
