Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a concrete pile head reinforcing bar for reinforcing the head of a concrete pile.

<Prior art> Concrete pile P used as a foundation of a building is
As shown in FIG. 5, it has a hollow structure in which an inner cavity H is formed, and it is used by being driven until it reaches a hard bedrock R.

However, since the distance to the bedrock R varies, it may be necessary to cut the extra protruding portion L after the driving in some cases. When cut, reinforcement of the head is required due to a problem in strength.

As shown in FIG. 6, the reinforcement of the head portion is carried out by hooking the reinforcement bar 1 on the top of the concrete pile P with the support rod 2, setting it in a suspended manner in the inner cavity H, and attaching it to the lower end of the reinforcement bar 1. Concrete is placed in the inner cavity H up to the receiving member 3.

By the way, conventionally, this reinforcing bar 1 is made on site. That is, the reinforcing bar is bent to form a spiral hoop muscle 4, and this hoop muscle 4 is usually welded to four main bars 5.

<Problems to be solved by the invention> However, the reinforcing bar 1 made on site in this way has variations in the spacing of the hoop muscles, variations in the arrangement of the main bars 5 or variations in welding, etc. It was insufficient.

In view of this, the present invention aims to provide a concrete pile head reinforcing bar that can be easily assembled by anyone and can always ensure stable quality.

<Means for Solving the Problems> The concrete pile head reinforcing bar according to the present invention includes a plurality of main bars, a plurality of annular hoop bars, and a plurality of restriction holes in order to achieve the above object. A base end regulating member for regulating the arrangement state of the main bar at the base end of the main bar by fitting the base end of the main bar into each of the restriction holes, and a plurality of insertion holes are provided. The front end regulating member that regulates the arrangement of the main muscles regulated by the base end regulating member on the tip side of the main muscle by inserting the It has a rope-shaped member such as a wire rope to be lowered and a synthetic fiber rope, and a locking member for locking the whole in a state of being suspended in the inner cavity of the pile and to the pile head.

<Operation> The concrete pile head reinforcing bar according to the present invention can always be obtained with stable quality by assembling each member produced in advance in the factory on site. That is, the arrangement of the main bars is determined by the base end regulating member and the tip side regulating member, and the distance between the hoop muscles is accurately determined by the attachment distance to the rope-shaped member. Since each hoop bar and rope-shaped member are joined at the factory, the main bar must be inserted into the insertion hole of the tip side regulation member and then fitted into the regulation hole of the proximal end regulation member for assembly work on site. All you need to do is let it work. That is, these assembling do not require any fixing work such as welding. Therefore, anyone can easily perform the work, and accurate work can be obtained without variations in quality depending on the skill level of the worker. Further, since the rope-shaped member is used as a member for connecting the hoop muscles, even if the rope-shaped member is attached to the hoop muscles at the factory, it can be folded and packed in a small size during transportation, which is convenient for transportation.
Further, at the time of construction, it can be easily set in the lumen by placing it on the pile head and unpacking it, so the construction method is good.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS.

10 is a concrete pile head reinforcement and 4 main reinforcements 1
1, 11, ... 4 annular hoop muscles 12, 12, ...
.., the base end regulating member 13, the tip side regulating member 14, the wire (rope-shaped member) 15, and the horizontal bar (locking member) 21.

The base end regulating member 13 has a tray 17 that performs the same function as that of the receiving member 3 described above, and is a member for regulating the arrangement state of the main bars 11 at the base end of the main bars 11.
That is, four arms 19 are radially projected from a central block 18 arranged at the center of the upper surface of the tray 17, and a restriction hole 16 for fitting the main bar 11 is formed at the tip of each arm 19. There is. Further, the central block 18 is provided with a lower fixed streak 20 having a T shape as a whole in an upwardly projecting manner, and the hoop streak 12 at the lowermost stage is joined thereto. The tray 17 is formed of a bottom plate 17a smaller than the inner diameter of the inner cavity H, and a peripheral wall 17b that extends upward from the peripheral edge of the bottom plate 17a so that the upper end portion has a diameter substantially equal to the inner diameter of the inner cavity H. ing.

The distal end side regulating member 14 is for regulating the arrangement state of the main bars 11 regulated by the proximal end regulating member 13 on the distal side of the main bar 11, and is similar to the regulating hole 16 in the proximal end regulating member 13. The four insertion holes 22 are provided in the arranged state. Specifically, the circular muscle 14a is bent at four bends 2
2b is formed in combination with the annular muscle 14c, and the insertion portion 22 is formed by the curved portion 22b of the annular muscle 14c and the annular muscle 14a. Since the distal end side regulation member 14 is formed by the combination of the annular muscles 14c and 14a, it also functions as the fifth hoop muscle.

The wires 15 are for positioning and supporting the hoop muscles 12 and the tip side regulation member 14 at a predetermined interval, and in this example, the three wires 15 have a central angle of approximately 120 °. 12 are evenly arranged and used. Then, the intervals of the hoop muscles 12 are determined by joining the hoop muscles 12 to the three wires 15 at a predetermined interval.

Then, the horizontal bar 21 as the locking member is provided with the annular muscle 14a,
It is joined to the upper side of 14c. That is, the circular muscle 14
The horizontal bar 21 is welded to the upper side of a, 14c with both ends projecting sufficiently outward from the circular muscles 14a, 14c, and hooked on the pile head to pierce the pile head reinforcing bar 10 as a whole. It is for hanging to H.

Since each of these members is manufactured in a factory in advance and the other portion 25 excluding the main bar 11 is integrated, the main bar 11 and the other part 25 are separately packaged during transportation as shown in FIG. It

The installation of the pile head reinforcements 10 at the site is performed first in the other part 2
5 is packaged and is hung in the inner cavity H by being hooked on the top of the concrete pile P by the horizontal bar 21. Then, the main bar 11 is unpacked, the main bar 11 is passed through the insertion hole 22 of the distal end side regulation member 14, and the base end portion thereof is fitted into the regulation hole 16 of the base end portion regulation member 13. The belt 26 packed in this state is cut, and the base end portion regulation member 13 is dropped into the inner cavity H (see FIG. 3). At this time, the base end regulating member 1
When 3 does not descend due to its own weight, the main bar 11 is pushed downward to descend. Then, when the wire 15 is fully stretched and is no longer lowered, the installation of the pile head reinforcing bar 10 is completed (see FIG. 4).

According to this embodiment configured as described above, each member is factory-produced in advance and the other portions 25 other than the main bar 11 are integrally combined, so that the consistent quality is always obtained. That is, the assembling work at the site is minimized, and the main bar 11 is inserted into the insertion hole 22 of the distal end side regulation member 14 so that the regulation hole 1 of the proximal end portion regulation member 13 is inserted.
6 and the other part 25 can be set in the inner cavity H by simply cutting the packing belt 26 of the other part 25. For this reason,
Anyone can easily perform the work, and accurate work can be obtained without variation in quality depending on the skill level of the worker. Also,
It can be installed very quickly, which is advantageous in terms of process.
Further, since the wire 15 is used as a member for connecting the hoop muscles 12, it is possible to carry out very small packing without hindering the packing, which is advantageous for transportation.

In the above embodiment, the base end restricting member 13 is joined to the lowermost hoop muscle 12 by the T-shaped lower fixing muscle 20 having an overall shape protruding from the central block 18 provided at the center of the tray 17. However, if the lower end of the wire 15 is directly joined to the saucer 17 without using the lower fixing bar 20, it becomes more advantageous in transportation.

Then, in the example described above, the wire 15 is used as the wire-shaped member.
Although the case where three wires are used has been described, the member is not limited to the wire 15 as long as it has a predetermined strength and is flexible and does not expand and contract, and the number of wires may be three or more.

Further, the example using the four main muscles 11 and the four hoop muscles 12 has been described, but the number of these is not limited to four.

<Effect of the Invention> The concrete pile head reinforcing bar according to the present invention has the contents as described above, and the assembly work on site is minimized by assembling each factory-produced member on site. It does not require any fixing work such as welding. Therefore, it is a work that anyone can easily carry out, and an accurate work can always be obtained without variations in quality depending on the skill of the worker. Further, since the rope-shaped member is used as a member for connecting the hoop muscles, it can be folded and packed in a small size during transportation, which is convenient for transportation. Furthermore, at the time of construction, it can be easily set in the lumen by placing it on the pile head and unpacking it.
Good workability.
