Description

  The present invention relates to a joint joint for upper and lower piles and a joint joint for members.

  For example, in the method of rotary press-fitting of steel pipe piles, methods using welding and screw-type joints have been proposed as methods for joining the upper and lower piles, but both require labor and are troublesome to join. There is a problem.

  Therefore, the inventor uses a male joint having an outer peripheral deformed portion and a female joint having an inner peripheral deformed portion, and these are attached to the lower end portion of the upper pile and the upper end portion of the lower pile, The deformed parts are fitted together so that they can rotate together, and in the fitted state between the deformed parts, a pin is inserted from the side so as to pass over the meat part of the male and female joints, and the joints do not separate in the separating direction. We are considering adopting a fitting joint that is jointed like this.

  However, a problem with the fitting joint as described above is how to ensure the integrity of the upper and lower piles when the joint portion is pulled or bent.

  In view of the above-described problems, the present invention provides a joint having a structure in which a fitted joint portion can maintain firm integrity against pulling, bending, and the like while being of a male-female fitting type. This is the issue.

Said subject is equipped with the male and female fitting type fittings attached to the lower end of the upper pile and the upper end of the lower pile,
The male joint has an outer peripheral deformed part, the female joint has an inner peripheral deformed part, and both joints are made to rotate together by fitting these deformed parts,
The pin for jointing the male and female joints in the fitted state between the deformed parts is a joint for joints of upper and lower piles inserted from the side so as to pass over the meat part of both joints,
The male and female joints are inclined at the peripheral surface so as to be taper-fitted,
The male and female joints are provided with one or more pairs in the fitting direction so that a pair of contact holes for deeply fitting these joints from the taper-fitted state is opened to the side,
The pin is solved by a joint joint for upper and lower piles, which can be inserted into the pin insertion hole in a state in which both joints are brought in using the insertion hole.

  In this joint, the male and female joints are configured to be taper-fitted, and the male and female joints are provided with one or more pairs of inlet holes in the fitting direction. Pins can be inserted after the male and female joints are pushed firmly in the mating direction using holes, and the mated joints maintain firm integrity against pulling and bending. can do.

  In this joint, the pin and the hole for inserting the pin are inclined at the peripheral surface so as to be inserted into the taper fitting state, and by inserting the pin into the insertion hole, the joint is further fitted deeply. And even better.

  In this case, the male and female joints can be fitted more deeply by inserting the pins, and the fitted joints can maintain firm integrity against pulling and bending.

  In addition, in a structure in which the pin and the insertion hole are tapered and are fitted more deeply by inserting the pin, the male and female joints are inserted with the pin inserted and the male and female joints joined. The pair of inlet holes may be at least partially in communication with each other.

  In this case, the joint between the male and female joints can be easily separated. That is, the male and female joints jointed with the pins are more deeply fitted by the driving of the pins, so that it is difficult to separate them simply by extracting the pins. However, since the pull-in holes of the pair of male and female joints are in communication with each other at least partially in a state where the pins are jointed, the male and female joints can be displaced in the separation direction by using the pull-in holes. Thereby, the male and female joints brought deeply can be easily separated. In some cases, the separation of the male and female joints may be necessary in the work of pulling and disassembling the pile after years of use.

Moreover, said subject is equipped with the male and female fitting type joint attached to the lower end part of an upper pile, and the upper end part of a lower pile,
The male joint has an outer peripheral deformed part, the female joint has an inner peripheral deformed part, and both joints are made to rotate together by fitting these deformed parts,
The pin for jointing the male and female joints in the fitted state between the deformed parts is a joint for joints of upper and lower piles inserted from the side so as to pass over the meat part of both joints,
The male and female joints are inclined at the peripheral surface so as to be taper-fitted,
The pin and the hole into which the pin is inserted has a peripheral surface inclined so as to be inserted into a taper fitting state, and the joint is deeply fitted by inserting the pin into the insertion hole. It is also solved by joints for joints of upper and lower piles.

  In this joint, the male and female joints can be deeply fitted by inserting the pins, and the fitted joint portion can maintain firm integrity against pulling, bending, and the like.

In addition, the above-mentioned problem is provided with a male and female fitting-type joint attached to one member and the other member,
The pin for jointing the male and female joints in the mated state of the male and female joints is a joint joint between members inserted from the side so as to pass over the meat part of both joints,
The male and female joints are inclined at the peripheral surface so as to be taper-fitted,
The male and female joints are provided with one or more pairs in the fitting direction so that a pair of contact holes for deeply fitting these joints from the taper-fitted state is opened to the side,
The pin can also be solved by a joint joint between members, wherein the pin can be inserted into the pin insertion hole in a state where both joints are brought in using the insertion hole.

In addition, a male and female fitting type fitting to be attached to one member and the other member is provided,
The pin for jointing the male and female joints in the mated state of the male and female joints is a joint joint between members inserted from the side so as to pass over the meat part of both joints,
The male and female joints are inclined at the peripheral surface so as to be taper-fitted,
The pin and the hole for inserting the pin are inclined so that the tapered fitting state is inserted, and the joint is deeply fitted by inserting the pin into the insertion hole. This is solved by a joint joint between the members to be connected.

  That is, these joints can be widely used not only for joints of upper and lower piles but also for joints between members, so that the fitted joint portions can maintain firm integrity against pulling or bending.

  Since the present invention is as described above, the fitted joint portion can maintain firm integrity with respect to pulling, bending, and the like while being of a male-female fitting type.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  The joint of the embodiment shown in FIG. 1 to FIG. 3 is used for jointing upper and lower piles used for driving by a rotary press-fitting method, etc. 1 is a female joint made of cast steel, etc. 2 is also cast steel 4 and 7, the female joint 1 is preliminarily welded to the upper end of the lower pile 4 whose base end is made of steel pipe or the like. The male joint 2 is attached and used in advance by welding or the like to the lower end portion of the upper pile 5 whose base end portion is made of a steel pipe or the like.

  The male joint 2 has a proximal half 2a with an outer circular shape and a distal half 2b with an outer peripheral drum shape, and the female joint 1 has a distal half 1a with an inner circular shape. The base end side half 1b is formed in an inner drum-like profile, the outer periphery circular base end side half 2a of the male joint 2, the inner periphery circular front end side half 1a of the female joint 1, and The outer peripheral drum-like distal half 2b of the male joint 2 and the inner peripheral drum-like proximal half 1b of the female joint 1 can be fitted with each other.

  In this fitted state, the joints 1 and 2 are engaged by the engagement in the rotational direction between the outer peripheral drum-like distal half 1b of the male joint 2 and the inner peripheral drum-like proximal half 1b of the female joint 1. , So that you can rotate around.

  Further, a step 2c provided between the base end half 2a and the tip end half 2b in the male joint 2 and a step 2c provided between the base end half 1b and the tip end half 1a in the female joint 1 are provided. The step 1c thus formed can withstand compressive force by abutting each other in the fitted state.

  Further, as shown in FIG. 3, the insertion holes 6 and 6 through which the joint pins 3 are inserted from the side in a state where the male and female joints 1 and 2 are fitted are formed into the drum-like fitting portions of the male and female joints 1 and 2. The male and female joints 1 and 2 are provided in a penetrating state so as to extend across the meat of the joints 1 and 2 so as to extend along the boundary portion of the straight portion. Is made to be jointed in the retaining state.

  The male and female joints 1 and 2 are configured such that the peripheral surface portions of the base end side half portions 1b and 2a and the tip end side half portions 1a and 2b are inclined and taper-fitted. The male and male joints 1 and 2 are fitted in such a way that a pair of insertion holes 7a and 7b for deeply fitting the joints 1 and 2 from the taper-fitted state opens sideways. The pins 3 and 3 can be inserted into the insertion holes 6 and 6 by using the insertion holes 7a and 7b to bring the joints 1 and 2 into the inserted state. That is, in a state where the male and female joints 1 and 2 are simply fitted, the structure in which the groove 6b on the male joint 2 side and the groove 6a on the female joint 1 side constituting the insertion hole 6 are large and the pin 3 cannot be inserted. Therefore, in this embodiment, as shown in FIG. 1, in the female joint 1, the pin insertion holes 6 and 6 and the insertion hole 7a are provided at the same height position. 2, the height positions of the grooves 6 b and 6 b for the pin insertion holes 6 and 6 and the insertion hole 7 b are different. In addition, the chamfering hole 7b is chamfered to call in the urging tool 8 at the upper and lower portions thereof.

  Furthermore, in the present embodiment, the peripheral surfaces of the pins 3 and 3 and the insertion holes 6 and 6 are inclined so as to be inserted into the tapered fitting state, and the pins 3 and 3 are inserted into the insertion holes 6 and 6. Thus, the male and female joints 1 and 2 brought in through the draw-in holes 7a and 7b can be further brought into closer engagement with each other.

  The joint of the upper and lower piles 4 and 5 using the above-mentioned joint is arranged above the lower pile 4 after the driving of the lower pile 4 is finished, as shown in FIGS. Then, it is lowered to the side of the lower pile 4, and the male and female joints 1 and 2 are taper-fitted. In this fitted state, as shown in FIG. 4B, the vertical displacement between the groove 6b on the male joint 2 side and the groove 6a on the female joint 1 side constituting the insertion hole 6 is large, and the pin 3 can be inserted. There is no state.

  Therefore, the pulling tool 8 is inserted into the pulling holes 7a and 7b of the male and female joints 1 and 2 and bent, and the male joint 2 is moved to the female joint 1 side by lever principle. As shown in FIG. 5C, the displacement of the grooves 6a and 6b of the pin insertion hole 6 is reduced to such an extent that the pin 3 can be inserted.

  Thereafter, as shown in FIGS. 5 (a) and 5 (d), the pin 3 is driven and inserted into the pin insertion hole 6, and the male and female joints 1 and 2 are further brought closer by taper fitting between the pin 3 and the insertion hole 6. Put it in a crowded state. In this way, the joint portions of the upper and lower piles 4 and 5 can be firmly integrated with respect to pulling and bending.

  In this fitted state, the drawing holes 7a and 7b of the male and female joints 1 and 2 are partially in communication with each other as shown in FIG. 2 can be decomposed as follows. That is, as shown in FIG. 6 (a), first, the pin 3 is pulled out. However, if the pin 3 is just pulled out, the male and female joints 1 and 2 are strongly drawn in, so it is difficult to separate them.

  Therefore, by using the above-described drawing holes 7a and 7b, as shown in FIGS. 6B and 7C, the drawing tool 8 is inserted into the drawing holes 7a and 7b, and the drawing tool 8 is inserted. Bending is applied, and the male and female joints 1 and 2 are relatively displaced in the separation direction by the principle of leverage. As a result, the male and female joints 1 and 2 that have been attracted strongly can be separated and the upper and lower piles 4 and 5 can be separated as shown in FIG.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the case where one pair of the entrance holes 7a and 7b is provided around the joint of the male and female is shown, but a plurality of the entrance holes 7a and 7b may be provided in the circumferential direction.

  Further, in the above embodiment, a case is shown in which a pair of the drawing holes 7a and 7b are provided in the fitting direction of the male and female joints. You may be made to be able to fit more deeply.

  In the above-described embodiment, the pair of access holes 7a and 7b of the male and female joints 1 and 2 are at least partially communicated with each other in a state in which the pin 3 is inserted and the male and male joints 1 and 2 are jointed. In the case where it is impossible to separate the male and female joints 1 and 2 or when other separating means are provided, the pair of access holes 7a, 7b may not be in communication with each other.

  Further, in the above embodiment, the pin 3 and the insertion hole 6 are taper-fitted so that the male and female joints 1 and 2 are further pushed in by the insertion of the pin 3. The taper fitting with the hole 6 may be omitted, and the male and female joints 1 and 2 may not be brought in by inserting the pin 3.

  In the above embodiment, the male and female joints 1 and 2 are provided with a pair of feeding holes 7a and 7b so that they can be brought in by the feeding tool 8, but the feeding holes 7a and 7b are omitted. The male and female joints 1 and 2 may be brought into the structure only by taper fitting between the pin 3 and the insertion hole 6.

  Furthermore, the joint of the present invention is not limited to the joint of the upper and lower piles used in the rotary press-in method, but can be used for the joint of the upper and lower piles in other driving methods, and is not limited to the case where the piles are connected to each other. In such a case, a co-rotation mechanism by fitting of deformed portions may be provided or may not be provided.
