Description

The present invention relates to a fixture for a stake, in particular, it is easy to adjust the height and inclination of the stake, and it is possible to use piles of different diameters and materials, such as wooden piles or reinforcing steel piles, depending on the construction site. It relates to a tension fixture.

2. Description of the Related Art At the site of civil engineering or building construction, the work of setting up the stakes for setting the standards of the height, position, direction, etc. of the building to be constructed is performed before or during the construction work. This consists of driving a plurality of piling materials (pile pilings) at predetermined intervals outside the territory defined on the basis of construction drawings, and attaching a horizontal piling board or the like to each pile using a level.

Conventional timbering was installed by driving a wooden board called a timbering board (trailing board) to a wooden stake with a nail. However, there is a problem that it is not easy to dismantle the nailed stakes, and it is difficult to reuse the stakes and stakes. In addition, there was a restriction that the stakes had to be made of wood because the nail was used to fix the plank.

In addition, as construction progresses, it may be necessary to temporarily remove and reinstall the finishing board in order to adjust the height and angle of inclination of the finishing board. In addition, after removing the nails from the stake board and adjusting the height, etc., the pile and the stake board must be fixed again with nails, which is a laborious and complicated work.

In addition, since it is not easy to drive wooden piles into frozen ground or bedrock, metal piles (for example, reinforcing rods) are sometimes used instead of wooden piles. In such a case, since nails cannot be used to attach the finishing board, it is necessary to attach the finishing board to the reinforcing steel pile by some means other than nails. are fixed to rebar piles. For this reason, many proposals have been made regarding fixtures for fixing the sticking board to the reinforcing steel pile (for example, Patent Documents 1 to 3). The technical content of conventionally proposed fixing tools for tie-up will be described below.

In Patent Document 1, a plate material support pipe (rectangular box body) into which a plate is inserted is fixed in a predetermined direction to a pile support pipe in which a vertical pile is fitted, and a set screw is attached to the vertical pile support pipe to support the plate material. A "survey pole assembly clamp" is disclosed in which the tube is provided with a nail hole or set screw.

Patent Document 2 discloses a piling device having a piling member made of metal or hard resin, a cylindrical portion fitted to the piling member so as to be vertically movable, and a dragonfly portion attached perpendicularly to the piling member. ing. Further disclosed is a configuration that allows the registration mark portion to rotate with respect to the pile.

In Patent Document 3, a tip sticking plate holding portion having a U-shaped cross section for gripping a sticking plate, a pile gripping portion connected to the center of the back surface of the gripping portion, and a connection that rotatably connects the two. A tie-down fixture is disclosed that includes a portion.

However, these patent documents deal with the problem of the present invention, which will be described later, that is, to adjust the height and inclination of the piling board, so that the piling board can be easily removed from the pile and attached. It does not suggest any solutions to the fixtures for tie stakes that can be used even if they are greatly changed.

Japanese Utility Model Laid-Open No. 5-2014 JP-A-2004-37154 JP 2018-185189 A

As described above, in civil engineering and construction work, as the construction progresses, there are cases in which it is necessary to temporarily remove the trimming board and adjust the height and inclination angle of the trimming board. In such a case, the fixture for stakes described in Patent Document 1 can use reinforced piles, so that piles can be driven into the frozen ground surface and hard ground, and the fixtures for stakes can be used to fix stakes. can also be fixed to rebar piles.

However, the fixing of the nailing fixture and the nailing board must be nailed through a nail hole formed in the nailing fixture. For this reason, in order to adjust the height of the cutting board, it is necessary to pull out the nails of the cutting board and fix the nails, and there is a problem that it is difficult to reuse the cutting board.

Since the tying device described in Patent Document 2 can use reinforced piles, it can be used even on a frozen ground surface or hard ground like the tying fixture of Patent Document 1. However, since the trimming board is held in the cylinder and fixed by fastening the cylinder to the pile member with the height adjustment screw provided in the trimming device, it is necessary to fine-tune the height and inclination of the trimming board. Even in such a case, loosening the adjusting screw causes the sticking device itself to come off the pile, making it impossible to finely adjust only the sticking plate. Moreover, there is a problem that the structure is complicated, the weight is high, and the cost is high.

In the fixing device for tying described in Patent Document 3, similar to the fixing device for tying up in Patent Document 1 and the tying device described in Patent Document 2, reinforced piles can be used, so that the frozen ground surface and hard ground can be used. It can also be used on the ground. However, since the knife sticking board is held by the knife sticking board holding plate formed in the knife sticking fixture, there is a problem that only the knife sticking board that fits within the width of the knife sticking board holding plate can be used. In addition, the structure is such that the reinforcing bar pile is held by a hollow cylindrical gripping plate. , there is a problem that the structure is complicated, the weight is high, and the cost is high. In addition, there is a problem that the retaining plate for the nail plate may come off from the welded portion and break depending on how it is handled on site.

As described above, the techniques described in Patent Documents 1 to 3 have the problem that they cannot easily cope with the fine adjustment of the height and inclination of the finishing board that occurs in accordance with the progress of construction work such as construction work. I have a problem like

A wide variety of piles are used, such as wooden piles (wooden round bars), reinforcing rods, iron pipes, iron bars, hard resin pipes, and the like. In addition, it is not uncommon for the diameter to vary greatly within the range of about 15 to 60 mm.

On the other hand, a large number of fixtures are used at one construction site and are relatively expensive. It is required to be used repeatedly at the construction site. A problem in reusing such a fixing device for a stake is the problem of adaptability to changes in the diameter of the stake.

In the prior art, as a method of detachably attaching a piercing fixture to a piercing pile, the piercing pile is inserted into a tubular member (sheath pipe, hereinafter referred to as a sleeve) provided in the piercing fixture, and the sleeve is inserted. A bolt or butterfly screw is screwed into the screw hole of the female screw provided on the side surface and fixed by pressing. As for the cross-sectional shape of the sleeve, as seen in the examples of Patent Documents 1 to 3, a circular one is used in most cases.

In order to use a thick pile, the diameter of the sleeve must be increased to some extent. However, the following problems are conceivable when a large-diameter sleeve is fixed to a thin pile. That is, in order for the pressing force of the locking screw to act properly, the axial center of the sleeve and the axial center of the piling pile must be aligned. hits the sloping surface of the pile, causing the pile to slip laterally and the tightening force to become insufficient.

In an actual field work, it is not always easy to align the sleeve and the pile so that their axial centers are aligned, which increases the labor of the work (there is a problem of alignment). Also, if the pile is thin with respect to the diameter of the sleeve, even if it is pressed so that the shaft center is aligned, the tip of the locking screw (usually a thick bolt-like screw is used) is flat. When a strong lateral force (especially an impact force) acts on the fixing fixture for finishing, the pile shifts sideways, and the pressing force of the locking screw does not work, causing the fixture for finishing to slide down. occurs (there is a problem of lateral displacement).

According to the experience of the present inventors, if the diameter of the pile is about 2/3 or more of the diameter of the sleeve, lateral displacement is not a big problem. was found to be a major problem. If the sleeve is cylindrical in this way, the pile and the sleeve contact at one point (straight line), which is likely to cause skidding.

Therefore, if the cross-sectional shape of the sleeve is changed so that the contact state between the sleeve and the pile is changed, it is conceivable that the responsiveness to changes in the diameter of the pile of the fixture for stakes can be greatly improved.

Therefore, the first object of the present invention is to facilitate the adjustment of the height and inclination of the cutting board and to reuse the cutting board, that is, to save labor and resources in the cutting work and to improve work efficiency. To provide a fixing tool for a tie which can contribute to In addition, in the tie-up fixture that fixes the tie-up board to the tie-up stake, the structure of the part where the tie-up fixture and the tie-up stake come into contact has been improved so that the diameter of the tie-up pile can be changed significantly. To propose a structure of a fixing tool for a tie-up which can deal with both (no problems such as position alignment and lateral displacement).

In order to solve the above problems, the present applicant has conceived the following. In other words, if the cross-section of the sleeve through which the pile is inserted is not circular, but has a pentagonal shape with a tapered tip, even if the diameter of the pile is significantly smaller than that of the sleeve, when the pile is pressed by the screw for locking the pile, the pile will not move. Since it fits into the tapered tip, there is no sideways movement. In addition, since the pile is supported on both sides of the tip, it is in two-point contact, and even if a strong lateral force acts on it, it will not slip laterally.

A nail sticking board is arranged so as to come into contact with the pile which is pressed and fixed by a sticking pile locking screw for pressing and fixing the pile, and the sticking board in such a state is pressed and fixed by the sticking board locking screw. structure. As a result, it is possible to independently perform the fixing of the stake with the fixing fixture for the finishing stick and the fixation of the fixing board with the fixing fixture for the finishing stick, making it easy to finely adjust the height and inclination of the finishing board. It can be carried out.

Based on the above idea, the nail sticking fixture of the present invention is a nail sticking fixture made of a metal frame having a V-shaped tip for detachably fixing a nailing board to a nailing pile. ,
A threaded hole for retaining a pinion pile formed in the back surface of the frame, and a threaded hole for retaining a pinion pile inserted through the threaded hole for locking a pinion pile and inserted into the front end side of the frame . a screw for locking a peg pile to be pressed and fixed;
A screwing member extending upright from the upper part of the back surface of the frame, a threaded hole for locking the nail plate formed in the screwing member, and a threaded hole for locking the nail plate. and a nail sticking plate locking screw for pressing and fixing the nail sticking plate abutting on the nailing pile.

In the above-mentioned fixing device for a tie-up, the frame has a pentagonal horizontal cross-section, is axially symmetrical with respect to the center line of the horizontal cross-section, and has the tie-up on the vertical center line of the back surface of the frame. It is desirable that the screw hole for locking the plate and the screw hole for locking the stake pile are formed vertically.

A finishing fixture of the present invention is a finishing fixture made of a metal frame for detachably fixing a finishing board to a finishing pile ,
The frame body includes a frame body side part made of a pair of band plates arranged facing each other at a distance equal to or larger than the diameter of the pile.
A front end portion of the frame connected to one end of the side surface of the frame and having a V-shaped tip, a rear portion of the frame formed of a band plate connected to the other end of the side surface of the frame, and a frame. A screw hole for locking a pinion pile formed in a rear portion, and a screw hole for locking a pinion pile, which is inserted through the screw hole for locking a pinion pile, and presses and fixes the pinion pile inserted through the front end side of the frame. a locking screw, a flat plate or U-shaped screw-fastening member extending to the upper part of the rear surface of the frame, a screw hole for locking the plate-hanging plate formed in the screw-fastening member, It is characterized by further comprising a tie plate locking screw which is inserted into the tie plate locking screw hole and presses and fixes the nail stake plate abutting on the tie stake.

The horizontal cross section of the frame body is a tapered pentagonal shape, and is axially symmetrical with respect to the center line of the horizontal cross section. It is desirable that screw holes for engaging the stake pile are formed at the top and bottom.

According to the fixing tool for nail sticking of the present invention, the height and inclination angle of the nail sticking plate can be easily adjusted, and the nail sticking work can contribute to labor saving, resource saving, and improvement of work efficiency. Fixtures can be provided.

In addition, when using the fixing device for a piling of the present invention, the piling pile pressed by the locking screw comes into contact with both sides of the front end of the V-shaped frame, so that a lateral force acts on the piling pile. However, there is absolutely no concern about sideways slippage. Also, if the pile is thin, the pile will go deep into the tip of the V-shaped frame, and if the pile is thick, it will stay in a shallow position. Since it is fixed on both sides of the tip of the frame, it can be used without any problem even if the diameter of the pile is greatly changed.

In other words, the ability to cope with large changes in the diameter of the stake pile is ensured, and as a result, the fixture for stake stakes of the present invention can be applied to any type of stake pile with a single fixture. , it has become possible to greatly expand the versatility of the fixture for hanging.

Preferred embodiments of the present invention will now be described with reference to the drawings of examples. 1A and 1B are diagrams showing the shape of the fixture for binding according to the present embodiment, FIG. 1(a) being a plan view, FIG. 1(b) being a side view, FIG. d) is a perspective view.

As shown in the figure, this fixture for binding is composed of a frame 1 and a screwing member 2. As shown in FIG. The frame body 1 has the function of inserting the pierced pile 10 into its interior and holding the pile by the pierced pile locking screw 11 .

This frame 1 has a pair of frame side portions 3a arranged facing each other at an interval equal to or larger than the diameter of the pile (see FIGS. 2 and 3) (assuming the expected maximum diameter). , 3b, a frame front end portion 4 formed at one end of the frame side portions and having a tapered V shape when viewed from above, and the other end portions of both frame side portions are connected. It is provided with an upright plate-like frame body rear portion 5 for sealing so as to form a sleeve. In addition, a screw hole 6 for engaging a stake pile is formed in the vicinity of the center of the back surface portion 5 of the frame body.

The frame body 1 is formed so that its horizontal cross section has a pentagonal shape with a tapered tip. It is pressed and fixed by a screw 11 for engaging a tip stake pile which is screwed into the . What is important in this case is that the pentagonal shape is axially symmetrical with respect to a normal line (upright line) passing through the center of the base (in this case, the back surface of the frame body 5). As a result, the central axis of the screw 11 for locking the pierced pile and the central axis of the pierced pile 10 are aligned with each other.

In the present embodiment, each of the frame body side portion 3, the frame body front end portion 4, and the frame body back portion 5 uses a band plate having a width of about 20 mm and a thickness of about 3 mm, and is made vertically. ing.
The material constituting the frame body 1 does not necessarily have to be a band plate except for the frame body back portion 5, and may be formed of, for example, a round bar or square bar. In addition, in this embodiment, the pair of frame body side portions 3a and 3b are parallel to each other, but this need not be the case. .

The screw-fixing member 2 is a plate-like member having a screw hole, and has a function of pressing and fixing the nail plate 12 by means of a nail plate locking screw 13 screwed thereto. The screwing member 2 is a plate-shaped member that stands upright on the extension of the frame rear surface portion 5 of the frame 1, and has a screw hole 7 for locking the binding plate in the vicinity of the center thereof.

In this embodiment, the screwing member 2 has a groove-shaped (U-shaped) cross-section formed by the flat frame portion 8 and the rising portions 9 formed on both side ends thereof. From the viewpoint of stably supporting the trimming board 12, the height of the frame plane portion 8 is preferably about the same as the width of the trimming board 12. As shown in FIG. Its thickness should be sufficient to form a female thread that is screwed into the locking screw.

In the present embodiment, the frame 1 and the screwing member 2 are integrally formed, but this is not always necessary. It may be joined by attaching, screwing or other means. However, it is preferable that the axial centers of the threaded hole 6 for locking the stake pile and the screw hole 7 for locking the threaded plate are arranged in the same vertical plane.

The rising portion 9 (sleeve portion 9) of the screwing member 2 in this embodiment is intended to reinforce the flat portion 8 of the frame body because the reaction force of the screw presser acts thereon. good too. Moreover, if necessary, it may be reinforced with a reinforcing member of another shape.

FIGS. 2A and 2B are diagrams showing a state in which a finishing board 12 is attached to a finishing pile 10 using the finishing tool of this embodiment, FIG. 2(a) is a plan view, and FIG. It is a side view. As can be seen in FIG. 2, the top-end pile 10 is pressed from behind by a top-end pile locking screw 11 (in this embodiment, a thumbscrew is used), and the frame tip of the frame 1 is pressed. 4, and is fixed in contact with the frame 1 at two points P1 and P2 shown in FIG. 2(a).

As described above, there is absolutely no concern about lateral slippage because the piling pile 10 is fixed by two-point contact. In addition, in a state in which the blade 12 is placed on the frame 1, the blade 12 is pressed from behind by a screw 13 (a thumbscrew in this embodiment) for locking the blade 12, and is pressed against the surface of the blade 10. fixed.

Since the axial center of the screw 13 for locking the pegboard is configured to coincide with the central axis of the cross section of the peg pile 10 , the pressing force acts on the axial center of the peg pile 10 cross section. Moreover, it is desirable that the tip of this screw be flat and perpendicular to its axis. As a result, even if the angle is not particularly adjusted, the trimming board 12 can be fixed in a state perpendicular to the axis of the trimming pile 10.例文帳に追加

Furthermore, if the tip of the screw is flat, it is possible to obtain the effect of preventing the rotation of the piercing board 12 pressed by the piercing pile 10 . In the case of the gate-type finishing board, since the finishing board is fixed by two or more stakes, the problem of rotation does not occur. However, in the case of the dragonfly-shaped tongs, since they are fixed by one pile, there is a concern that the tongs tongs 12 may wobble when a force is applied to turn them around the piles.

If the tip of the screw is convex, there is a possibility that it will wobble because it will hold the knife board at one point. An effect similar to that of supporting at two points can be obtained, and wobble can be avoided.

Furthermore, although not included in the configuration of this embodiment, a T-shaped or Y-shaped pressing member is detachably attached to the tip of the locking screw so as not to rotate in conjunction with the screw. By adopting this method, it is possible to more reliably prevent the sticking board from wobbling.

3A and 3B are diagrams for explaining the state of fixation in the frame when the fixing device for tying according to the present invention is used for tying piles having different diameters. FIG. 3(a) is for thin tying piles. , Fig. 3(b) shows the case of a thick pile. Each is a horizontal cross-sectional view of the frame at the height of the axis line of the screw 11 for hooking pile locking.

As can be seen in FIG. 3, the piling pile 10 is pressed by the tip of the piling pile locking screw 11 and comes into contact with the inside of both inclined surfaces of the V-shaped frame tip portion 4 of the frame body to be fixed. be done. At that time, the screw hole for fastening the stake pile is provided so that the central axis of the screw 11 for fastening the stake pile coincides with the normal line (upright line) X passing through the center of the back surface portion 5 of the frame. there is Further, both inclined surfaces of the frame tip portion 4 are formed axially symmetrical with respect to the normal line X. As shown in FIG.

Therefore, regardless of the thickness of the pile 10, the center line of the cross section of the pile is positioned so as to match the normal line X. That is, by inserting the peg 10 into the frame 1 and pressing it with the peg-pile locking screw 11, the center of the peg-pile locking screw 11 can be aligned with the peg-pile without any special positioning operation. 10 will abut on the center line of the cross section.

This principle applies exactly the same regardless of the thickness of the stake, thus facilitating the task of fixing the stake fixture to the stake. Thus, it is one of the important characteristics of the fixture for stakes of the present invention that the center of the stake can be automatically held down without special positioning operation.

FIG. 4 is a construction state diagram of a nail stake using the nail stake fixture of the present invention at a civil engineering construction site as an example. The piling pile 10 is a reinforcing rod, and the piling board 12 is hung on the two piling piles 10 in a gate shape. In FIG. 4, two tiered piercing boards 12 are fixed to piercing piles 10 by piercing fixtures, and the inclination of the upper tiered piercing board 12 to the ground surface is measured with a level. When the angle of inclination of the piercing board 12 is slightly different, the piercing board 12 can be adjusted while maintaining the fixation of the piercing pile 10 and the piercing fixture by loosening the piercing board locking screw 13. Adjustment can be easily performed.
