Description

The invention relates to the construction, namely, to the structures of the butt joints of the sections of driven piles.

Known butt joint sections piles comprising 5 disposed in abutting end face of each of the conical sections with a hollow sleeve disposed inside rigidly attached to its end a conical spacer, and a connecting member cylinders nonstoichiometric ⁰ 'with the slots on kon'tsam whose length exceeds the distance between the ends of the sleeves £ 1)).

The disadvantages of this compound is its low carrier ¹⁵ NOSTA ability to tensile forces and the inability to dismantle for repeated use if necessary.

The technical essence and the achieved result is a butt joint of pile sections, including end plates installed at the ends of the joined pile sections, one of which is equipped with core releases,. wound up in nests formed in another section, having plates overlapping them with openings and fixing devices (2].

Rod issues in this junction ^{30 are} made with spiral winding, which ensures their fixation in the plates. However, this compound has insufficient rigidity, because placement rod ³⁵ You are a start spiral-wound in an aperture plate requires at least a minimum clearance between the aperture and wound to besprepyatstlp

appearance of backlash in the joint and significantly reduces the stiffness of the joint. In addition, spring-loaded stops, fixing the plate after docking, also require the creation of a certain gap between them and the walls of the side groove of the plate for reliable operation of the lock when joining, which also increases the play in the joint.

This joint does not provide the possibility of dismantling in the case of extraction of piles for reuse.

The aim of the invention is to increase the stiffness of the connection and facilitate dismantling.

This goal is achieved by the fact that in the butt joint of pile sections, including end plates mounted on the ends of the joined sections of piles, one of which is equipped with rod outlets, which are inserted into nests formed in another section, having plates with holes and fixing devices that overlap them, are installed with reciprocating movement and interaction with locking devices and made in the areas of location of the core release with the lower, inclined surface, and the holes in them are made in the form of longitudinal slits, and the core outlets are provided with widened heads located at their ends at an angle to the vertical, adjacent to the inclined surface of the plates.

In addition, each locking device can be made in the form of a wedge, placed between

adjacent plates and provided with a hole through a hole formed in the wall of the head, with a nut.

Each plate can be 5

filled in the form of a single element overlapping a pair of sockets, the length of which corresponds to the width of the joined sections, provided with a shank and a nut, and the fixing device is made in the form of a hole of a bolt ¹ that interacts with the nut through the wall of the headband.

FIG. 1 shows a butt joint, side view; in fig. '2 section A-A in FIG. one; in fig. 3 section bb in fig. 2; 4 shows a butt joint using plates with two slits, top view 20; in fig. 5 is a sectional view BB in FIG. four.

Butt joint contains ogolovniki 1 and 2, mounted on the ends of the joined sections 3 and 4 piles. 25 Ogolovnik 1 contains core releases 5, and in section 4 sockets 6 are formed, which have plates 7 overlapping them with openings 8 and locking devices 9. 30

The core outlets 5 are provided with widened heads 10 at the end located at an angle to the vertical, and the plates 7 are made with the lower inclined surface 11 in the areas of the location of the core outlets 5, i.e. wedge-shaped.

Nests 6 are made in the form of skosny horizontal cavities serving as guides for plates 7, which are installed with the possibility of translational movement along them and interacting with locking devices 9. The locking device 9 for wedging plates 45 7 can be made in the form of a wedge 12 placed between the plates 7 and equipped with a pitch 13, passed through the hole 14 of the wall 15 of the head end 2 and fitted with a nut 16. 50 The locking device 9 also serves as a lock for the butt joint. Holes 8 in the plates 7 are made in the form of longitudinal slits. Each plate 7 can be made in the form of a single element, overlapping a pair of sockets 6, the length of which corresponds to the width of the joined sections

3 and 4 and has in this case two slots 8 for the corresponding core outlets 5. One of the two slots is provided with an opening 17 for the passage of the head 10 of the outlets 5.

Plate 7 is made with a shank 18 for its jamming. By means of a percussion instrument, for example a hammer (not shown). In this case, the latch plate 7 serves as a bolt 19, passed through the hole in the side wall of the end cap and interacting with the nut 20 welded to the plate 7.

Butt connection works as follows.

Before docking, unscrew the nut 1 6 and translate the wedge 12 deep into the head end 1, and the plates are pushed inside the nests 6. Then the rod outlets 5 of the head end 1 are lowered into the sockets 6 until the end heads touch each other.

Rotation of the nut 16 translates the wedge 12 into the gap between the plates 7, which slide along the guide slots 6, the slits 8 engage with the rod outlets 5 and, thanks to the inclined surface 11, provide wedging between the head 10 and the upper part of the tip 2 with simultaneous fixation of the wedging nut 16 , resulting in the disappearance of any backlash between the ends and the high rigidity of the connection.

If it is necessary to dismantle the butt joint, in case of removing sections 3 and 4 of the piles for reuse, the nut 16 is unscrewed and the wedge 12 is withdrawn from contact with the plates 7, which are then shifted into the nests 6 and come out of the engagement with the rod releases 5, after which the latter are freely removed.

In the case of the plates 7 as a single element for a pair of sockets 6 having two slots 8, these plates are pulled out of the sockets 6 so that the hole 17 coincides with the socket 6, after which the core outlets 5 are lowered into the sockets 6 until the end portions of the heads meet between themselves. After the blow of the hammer (not shown) on the shank 18, the plates 7 are engaged with the pivotal issues.

p by changing the thickness of the plates due to the inclination of the surface 11, spacer forces are created between the head 10 and the end part of the head 2.

Fixing plates 7 in the workplace 5

the position is carried out by screwing the bolt 19 into the nut 20.

If it is necessary to dismantle the butt joint, the bolt 19 is unscrewed from the nut 20, after which, 0 of the plate 7 is removed from the hammer with the rod outlets 5 and the joint is disconnected.

Technical and economic efficiency of the proposed joint is to increase the stiffness of the joint, which ensures high bearing capacity and reliability of the piles, especially when subjected to vibration operating loads and tensile forces at the joint, and the ability to dismantle the joint for reuse of piles reduces labor costs for the butt construction compounds 1.3-1.5 times.
