Description

BACKGROUND OF THE INVENTION
The present invention relates to a connection assembly between a cross-sectionally U-shaped guide profile of a retaining wall support element and a spreader flexibly mounted in the guide profile.
A connection assembly of this type is known from DE
3,909,110 Al. With this connection assembly it may happen that due to the high force of pressure applied by the dredger or pile driver that forces the retaining wall slabs into the soil, the compression spring unit loaded at the given moment is too weak, and the spring connection is thereby disconnected. The dredger operator often fails to notice that the spring is overloaded, which may lead to undesirable failure as well as leading to deformations and distortions which are also undesirable.
The known prior art offers no other effective possibilities for reinforcing the compression spring units.
In case of overload of the compression spring unit, there is no provision made for a rigid stop of the lateral legs on the guide profile. Another prior art drawback is that the attaching bolts, which are required for connecting the support shoe with the guide profile, are relatively expensive in terms of manufacture and installation, and frequently are lost in the soil. Furthermore, they are highly exposed to corrosion.

SUMMARY OF ~HE INVENTION
It is an object of the present invention to provide a connection assembly for increasing the spring force acting on the support plate without substantially enlarging the construction of the support shoe, and for permitting the support shoe to be extended as far as possible within the elastic range.
The above object is accomplished according by providing a connection assembly between a cross-sectionally U-shaped guide profile having a longitudinal axis of a retaining wall support element and a spreader having a free end flexibly mounted in the guide profile having a bridge comprising a support shoe comprising an oblong support profile with an H-shaped cross section. The oblong support profile has a longitudinal axis parallel with the longitudinal axis of the guide profile and projecting into the axis. The H-shaped cross section of the support profile is an H-shaped bridge and forms a support plate. The support plate has an upper side facing the spreader and the upper side supports a receiving device for the free end of the spreader. The support plate has a bottom side facing the guide profile and the bottom side supports each side of a longitudinal center plane of the spreader, the longitudinal center plane vertically crossing the longitudinal axis of the support plate. A lower compression spring unit supports itself on the bridge of the guide profile, and the lower compression spring unit has a length greater than the height of the lower lateral leg parts of the H-shaped support profile. The lower lateral leg parts are formed by flanges of the I-beam or H-bridge of the support profile and extend from the bottom side of the support plate.
209238~
The lower lateral leg parts are a spaced distance from the guide profile so as to provide a clearance space, the guide profile forming a box-shaped pocket for receiving the support shoe. The box-shaped pocket is formed by an upper pair of walls and by a lower pair of walls formed by walls disposed in each case on the bridge with a small spacing between each wall of the pair of walls and on flanges of the guide profile. The guide profile has~on its bridge in the center plane of the pocket the plate extending perpendicular to the longitudinal axis of the pocket. A bearing bushing is rigidly joined to the bridge and has a longitudinal axis being directed perpendicular to the longitudinal axis of the guide profile.
A cylinder is received in the bearing bushing and engages the bearing bushing on the bottom side of the support plate of the support profile. An upper compression spring unit for each lower compression spring unit is mounted on the top side of the support plate in alignment with the lower compression spring unit. The upper compression spring unit has a length greater than the height of upper lateral leg parts of the support profile. The upper lateral leg parts extend from the top side of the support plate and are formed by the H-flanges of the support profile. A holding angle has two legs, with one leg of the holding angle being detachably connected with the respective pair of walls, the leg positioned in the spacing between the walls of each pair of walls. The other leg of the holding angle is an overlapping abutment for gripping the respective upper compression spring unit positioned on the top side of the support plate.
The connection assembly no longer necessitates using a bolt bearing for the support shoe on the guide profile, but makes use of a box-shaped pocket for receiving the support 20~238~
shoe. In this way, guide profiles that project beyond the inner surface of the retaining wall support elements and attaching bolts as well as complicated recesses for inserting the attaching bolts are avoided in these retaining wall support elements where the guide profile is already integrated into the body of the retaining wall element.
However, the important advantage of the invention is that when the support shoe is stressed, two compression spring units loadable in each case with pressure diagonally relative to each other will act via corresponding lever arms of the support plate. These spring units will elastically absorb the motion of the support plate, permitting the absorption of a considerable impact force. Contrary to the prior art devices, the lateral legs of the support profile in the present invention provide lateral support for the compression spring units, and no longer function as a stop means. No provision need be made for a rigid stop means.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings which discloses an embodiment of the present invention. It should be understood, however, that the drawings are designed for the purpose of illustration only and not as a definition of the limits of the invention.
In the drawings, wherein similar reference characters denote similar elements throughout the several views:
FIG. 1 shows a longitudinal section view through a connection assembly according to line I-I in FIG. 2;
FIG. 2 shows a cross section according to line II-II
in FIG. l; and FIG. 3 shows a cross section according to line III-III in FIG. 1.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Turning now in detail to the drawings, when a ditch is blocked, two retaining wall support elements 1 are positioned opposite to each other in each case and are kept spaced apart by the spreaders 4. The retaining wall support elements 1 are alternately driven into the soil by means of a pile driver or a power shovel. In this connection, the spreaders assume relative to the retaining wall support element an inclined angular position deviating from a right angle. This angular position may not exceed a defined angular amount, e.g., 7, as the retaining wall geometry is changed otherwise.
The drawing shows a retaining wall element 1, for example a retaining wall slab or a support in which a U-shaped guide profile 2 is integrated, and this profile is arranged perpendicular to the bottom of the ditch. A support shoe 3 is supported in guide profile 2 and fastened on the respective end of a spreader 4. The guide profile 2 does not project beyond inner surface 5 of the retaining wall element 1. A
box-shaped pocket 10 is formed by means of an upper and a lower pair of walls 6, 7 disposed vertically on bridge 8 and 2~92385 transversely to flanges 9 of the guide profile 2. Each pair of walls 6 and 7 are spaced a small distance from each other to form a pocket therebetween. The pockets receive the support shoe 3. In the vertical center plane transversely to the pocket 10, a bearing bushing 11 is fastened on the bridge 8 of guide profile 2.
Support shoe 3 substantially comprises a support profile 12 having an H-shaped cross section; the bridge of this profile forms a support plate 13 and its flanges form the upper and lower lateral leg parts 14 and 15, respectively.
The outside dimensions of support profile 12 are selected in such a way that lower lateral leg parts 15 are positioned a spaced distance from guide profile 2 to provide a clearance.
On the underside 16 of support plate 13, a cylinder 17 (e.g., a tube) is fastened transversely to the longitudinal direction of this plate. The cylinder corresponds to bearing bushing 11 and is held within the bearing bushing. The bearing bushing does not require any special surface coating or treatment.
on the top side 18 of support plate 13, a receiving device 19 in the form of a sleeve is fastened to the free end of spreader 4. Spreader 4 is locked on receiving device 19 by means of a locking bolt 20 or the like, as shown in FIG. 3.
On both sides of the longitudinal center plane of spreader 4, extending through the axis of cylinder 17, are disposed lower compression spring means 21 spaced from each other on the underside 16 of the support plate. Spring means 21 is supported on bridge 8 of guide profile 2.
~:~ 209238S
Upper compression spring means 22 is mounted in each case on the top side 18 of support plate 13. Upper compression spring means 22 are aligned with each respective lower ¢ompression spring means 21. The upper compression spring means are supported in each case on a leg 23 of a holding angle member 24. The other leg 25 of angle member 24 is inserted into the space between the pairs of walls 6 and 7, respectively, and detachably connected with these walls by means of a bolt 26 or the like. Each compression spring unit 21 or 22 preferably includes oppositely wound screw compression springs arranged concentrically within each other.
In each case the inner compression spring 27 supports an outer compression spring 28. In this connection, the inner compression spring 27 is in each case shorter in length than the length of the outer compression spring 28 surrounding it.
However, the inner spring i8 longer in length than the height of the lateral leg part 14 or 15 of the support profile 12, with this part being directed away from the support plate 13.
The uppermost coil of each outer compression spring 28 resting against support plate 13 is drawn into the clearance space limited by the inside diameter of compression spring 28. The uppermost coil of each inner compression spring 27, at the end resting against support plate 13, is bent by 90 into the longitudinal center plane of the compression spring 27, forming the bow or spring anchor 30.
Spring 27 projects through a slot (not shown) in support plate 13, and is detachably fastened onto this plate by means of a clamping plate member 31 or the like.
In a practical method of application of the invention, holding angle members 24 are loosened, and support 209238~
shoe 3 is inserted into pocket lO so that cylinder 17 i6 received and held by bearing bushing 11. Subsequently, holding angle members 24 are plugged in against the force of upper compression spring means 22 and then locked into place.
During the reciprocal driving of the retaining wall elements 1 into the ground, support shoe 3 pivots around the axis of its cylinder 17. Simultaneously, support plate 13 supports itself on guide profile 2 by means of lower compression spring unit 21 and by means of upper compression spring means 22 (by means of holding angle member 24). Upper spring means 22 is arranged diagonally relative to lower spring means 21. This double arrangement of compression spring means 21, 22 simultaneously supporting themselves provides an elastic resistance or force counteracting the driving force of the dredger. This unique resistance force is also noticeable by the operator of the dredger.
The novel connection assembly of the invention does not require any critical tolerances or expensive surface treatments. All fastening means can be easily mounted and detached, and secured on the retaining wall parts by means of chains or the like in such a way that they will not be lost in the soil. The simple support of the support plate replaces the costly support used heretofore, with bearing bolts inserted in the guide profile, and is of greater overall strength.
While only a single embodiment of the present invention has been shown and described, it is to be understood that many changes and modifications may be made thereunto 2~92385 without departing from the spirit and scope of the invention as defined in the appended claims.
