Description

  The present invention relates to a separator that supports a concrete mold, and more particularly, to a separator fitting used for connecting separators.

  When building a concrete structure, the width, height, length, etc. of the concrete wall are determined by the formwork. The formwork is composed of a support plate that directly supports the concrete to be placed and a support that supports the support plate from the outside. In addition to plywood and steel plates, wooden panels and steel panels that are reinforced with a stile or an intermediate rail are used as the dams. Square members, pipes, and steel molds are used for the support work. Furthermore, a separator is disposed between the slats in order to maintain a space between the slats disposed facing each other across the concrete placing portion. Since the distance between the slats is the thickness of the concrete wall, the separator needs to have a length that matches the thickness of the wall.

  If the thickness of the concrete wall is not constant and the cross-sectional shape is a trapezoidal wall, etc., the length of the separator will change stepwise depending on the height from the ground, so various lengths are required. Become. On the other hand, since the lengths of the separators are not so diverse, a separator having a desired length is obtained by connecting two separators in the middle.

  FIGS. 5A and 5B are diagrams showing an example of a conventional separator fitting, wherein FIG. 5A is a plan view showing a use state, and FIG. 5B is a side view of the separator fitting. The separator coupling metal fitting 10 shown in these figures has a hexagonal column shape, and has a female screw hole 11 formed through the central axis. An external thread is engraved at the end of the separator, but its length is constant. Therefore, the length of the separator coupling fitting 10 is twice the length of the male screw formed on the separator. Therefore, when the male screw formed at the end of the reference separator 12 is screwed from one side of the female screw hole 11 and tightened, the male screw of the reference separator 12 is tightened at the center of the length of the female screw hole 11. It will be fixed. Then, a male screw formed at the end of the other adjustment separator 13 is screwed from the opposite side of the separator fitting 10. The reference separator 12 and the adjustment separator 13 are in contact at the center of the female screw hole 11.

  Pecons 14 and 14 are screwed to the other ends of the reference separator 12 and the adjustment separator 13. The peakon 14 has a truncated cone shape with a bottom surface 14a in contact with the sill plate of the formwork, and a shaft 14b penetrating through a hole formed in the sill plate and a male screw and a foam tie shaft formed at the tip of a shaft portion (not shown). It is fastened and fixed to the board. The distance between the bottom plates 14a and 14a when the peak separators 14 and 14 of the reference separator 12 and the adjustment separator 13 are fastened and fixed to the respective bottom plates is the distance between the bottom surfaces 14a and 14a of the peakon 14. Although this distance L is regarded as the length of the separator and is held at a desired interval, the following method has been used.

The length of the reference separator 12 is the distance L1 from the bottom surface 14a of the peakon 14 to the tip surface of the separator fitting 10, and the length of the adjustment separator 13 is L2 as shown. And
L = L1 + L2
The relationship holds.

  Since the distance L varies as described above, it is possible to obtain a desired length L by making the length L1 of the reference separator 12 constant and changing the length L2 of the adjustment separator 13 by cutting or the like. Become. Therefore, conventionally, the adjustment separator 13 is an all screw separator in which screws are engraved over the entire length, and this separator is cut to a required length and used.

  A high-speed cutter is used for cutting the adjustment separator 13, but since this high-speed cutter is heavy, the mold craftsman cannot carry it around and is used by being installed at a fixed position. And since only one or two units are placed even at a large construction site, in order to cut the adjusting separator 13 to a required length, it is necessary to walk to a place where a high-speed cutter is located. Furthermore, since the screw cannot be screwed only by cutting, it is necessary to chamfer with a grinder, which requires a considerable amount of time.

  As another method, there is a method of connecting using a turnbuckle described in Patent Document 1 (Japanese Utility Model Laid-Open No. 56-30255). However, this method has a narrow adjustable range. Further, a right-hand thread must be formed on one separator and a left-hand thread must be formed on the other separator, which complicates the management of the separator.

  Furthermore, there exists a coupling metal fitting shown in FIG. 6 as another method. In this case, a hole 22 through which two separators can be inserted with a slight gap is formed in a block 21 which is a main body of the coupling fitting 20, and a fastening member 23 is attached in a direction intersecting the hole 22. is there. The tightening member 23 has a rod-like shape in the center of the hole 22 and has a shape in which a nut 23b is screwed into an upper male screw 23a, a middle portion is narrowed, and a lower portion is gradually thickened.

When the two separators 12 and 13 are inserted into the holes 22 so as to be on both sides of the tightening member 23 and the nut 23b screwed into the male screw 23a formed on the tightening member 23 is turned, the lower portion of the tightening member 23 is The thick part of the plate is raised in the direction of the arrow a, the two separators 12 and 13 are moved in the direction of the arrow b to widen the interval, and the two separators 12 and 13 are pressed against the both side surfaces of the hole 22, At the same time, it is fixed and held at a predetermined length L.
Shokai 30-30255

  However, when the two separators 12 and 13 are fastened and fixed simultaneously by one fastening member 23, the separators 12 and 13 are easy to move during the fastening operation, and it is very difficult to maintain a desired length.

  The present invention has been conceived from such a situation, and an object of the present invention is to provide a separator fitting for connecting two separators, which can reliably hold a desired length.

  In order to achieve the above object, the separator fitting of the first invention of the present application is a separator fitting in which two separators, a basic separator and an adjusting separator, are connected to form a separator having a desired length. The body is formed with a female screw hole for screwing and fixing the basic separator at a fixed position by screwing with a male screw formed at an end of the basic separator, and a through hole through which the adjustment separator passes, A fastening member provided in the through hole so as to be movable back and forth in a direction crossing the through hole, and a moving member for moving the fastening member forward and backward are provided in the coupling metal body, and the adjustment separator is inserted into the fastening member.

When moving in the direction, is characterized in that said inclined surface portion is fixable axial movement of the adjusting separator in pressure contact with the adjusting separator.

  The insertion part of the tightening member is an insertion hole through which the adjustment separator can be inserted, the large diameter part through which the adjustment separator can be inserted, and the small diameter part which is continuous with the large diameter part and is smaller than the diameter of the adjustment separator. The slope portion is formed between the large diameter portion and the small diameter portion.

  Further, the separator fitting of the second invention of the present application is a separator fitting for connecting two separators of a basic separator and an adjustment separator to obtain a separator having a desired length. A female screw hole that is screwed with a male screw formed at an end to fasten and fix the basic separator at a fixed position, and a through hole through which the adjustment separator passes, and a through hole is formed in the through hole. A fastening member provided so as to be movable back and forth in a crossing direction is provided, the fastening member has an insertion hole through which the adjustment separator can be inserted, and a moving member for moving the fastening member forward and backward. The adjustment separator is inserted by passing through the overlapping portion of the through hole and the insertion hole, and when the moving member moves the tightening member in a direction intersecting the through hole, the shift between the through hole and the insertion hole causes the adjustment separator. It is characterized in that the axial movement is fixed.

As described above, the reference separator 12 and the adjustment separator 13 can be connected to obtain a separator having a predetermined length. Since the adjustment separator 13 can stop slipping at the female screw portion of the through portion 313, the adjustment separator 13 may not be a full screw separator. Although not shown, the through portion 313 may be formed with a non-slip projection as shown in the first and second embodiments, instead of the female screw.

  4A and 4B are diagrams showing a fourth embodiment of the separator fitting according to the present invention, wherein FIG. 4A is a plan view showing a usage state of the separator fitting, FIG. 4B is a cross-sectional view of the fitting main body, and FIG. FIG. 4B is a cross-sectional view taken along the line II of FIG. 4B, and FIG. 4D is a view of the separator fitting from J of FIG.

  The coupling metal body 410 of the separator coupling metal 400 has two parallel through holes. One has a female screw hole 411 at the left end, and a through hole 412 follows the female screw hole 411. The other is a female screw hole 413 on the right end side, and a through hole 414 is continuous on the left end side. Further, a screw hole 415 is formed at the center of the coupling metal body 410 in a direction orthogonal to these through holes, and a bolt as a tightening member 420 is screwed into the screw hole 415. 420 can be exposed to both through holes 412 and 414 arranged in parallel.

  Next, a method of connecting the reference separator 12 and the adjustment separator 13 with the separator fitting 400 will be described.

  First, the male thread of the reference separator 12 with the peakon 14 attached to one end is inserted through the through hole 412 of the separator fitting 400, screwed into the female threaded hole 411, and fastened and fixed, as in the third embodiment. The length L1 of the reference separator shown in 4 (a) is determined.

  Next, the peakon 14 is attached to the adjustment separator 13 for all the screws, inserted through the through hole 414, inserted into the through portion 313, and screwed into the female screw hole 413. And the length of L2 is measured with a ruler, the rotation of the adjustment separator 13 is stopped at a predetermined position, and the bolt of the tightening member 420 is rotated. Then, the tip of the bolt pushes the two separators 12 and 13 simultaneously, and the adjustment separator 13 is fixed. Since the basic separator 12 is fixed by the female screw 411, the tightening member 420 receives a reaction force from the basic separator 12 and can use this for fixing the adjustment separator 13. Therefore, the adjustment separator 13 is fixed by a larger force. As described above, the reference separator 12 and the adjustment separator 13 can be stably connected to obtain a separator having a predetermined length.

  In this embodiment, the through hole 414 and the female screw hole 413 are used, but a through hole without a screw may be used, and conversely, all may be a female screw hole. Moreover, the adjustment separator 13 can also use the normal separator which has an external thread only at an edge part.

  In the conventional separator shown in FIG. 5, every time the separator is connected, the entire thread separator is cut to a desired size, but this is not necessary in the present invention. This is because it can be fixed at any position of the entire screw separator. Moreover, as an adjustment separator, it can prepare for every 50 mm like 100 mm, 150 mm, and 200 mm, and can use the thing of the nearest length. Moreover, in the Example of this invention, although the screw is formed over the full length of a separator, it is not limited to this. The length of the screw portion may be 50 mm or 100 mm, and the screw portion other than the screw portion at the other end may be screw-free.
