2. Description of the Related Art Conventionally, as a telescopic structure of this type, a male screw is cut on an outer peripheral surface of a base portion of an outer tube, and a short operating ring having a female screw cut on an inner peripheral surface is screwed to the male screw portion. A pin protrudes from the outer peripheral surface of the inner tube, and a tip end of the pin protruding from a long hole formed in the male screw portion along the axial direction is supported by an end peripheral edge of the operation ring.

However, in this configuration, since the outer tube is directly threaded, the mortar or the like that falls from the gap of the mold is solidified by the threaded portion, and the mortar and the like are subsequently solidified. Could hinder proper use. Moreover, in this state, it is impossible to replace only the telescopic structure, and the entire concrete support rod including the outer pipe and the inner pipe must be replaced with a new one, which increases the cost of concrete placing work.

[0004] In addition, the operating ring screwed to the outer tube must be rotated around the outer tube having a relatively large diameter.
When the spacing between the supporting rods is not sufficient and the working place is narrow, the operation ring turning operation is not always easy. There is no suitable tool for such operation, and the length of the thread to be slid for a certain screwing distance is large, requiring extra force to overcome frictional resistance There was also a problem.

Accordingly, an object of the present invention is to telescopically fit a connecting pipe shorter than the outer pipe around the outer pipe base.
The connecting pipe and the inner pipe are connected by pins, and brackets are protruded from the base of the outer pipe and the tip of the connecting pipe, and adjustment bolts of long legs are inserted into the round holes and the female screw holes formed in these brackets. Another object of the present invention is to solve various problems of the conventional support rod expansion / contraction structure at once by adopting a screwed configuration.

SUMMARY OF THE INVENTION A concrete form supporting rod telescopic structure according to the present invention, which has been made to achieve this object, comprises an inner pipe, an outer pipe, a connecting pipe, a connecting pin, and an adjusting bolt. A plurality of pin holes are formed in the inner tube at appropriate intervals in the axial direction, and a connecting pin that can be selectively set in the pin hole is attached to a base side of the connecting tube. Along the entire length in the axial direction, a long hole is formed, and a free rotation of the leg portion of the adjusting bolt is allowed from a base side portion of the outer tube slidably housed inside the connecting tube. To this end, a first bracket provided with a round hole without a female screw is mounted so as to protrude outward through the elongated hole. A second bracket protrudes from the distal end portion of the connecting pipe in the same direction as the first bracket.
A female screw hole concentric with the round hole is drilled in the outer protruding portion of the bracket, and a male threaded leg is inserted into the round hole with the head facing the connecting pipe base side. The connection pipe and the inner pipe are relatively slid with respect to the outer pipe by rotating the adjustment bolt having the tip end side of the leg screwed into the female screw hole when the connection pin is set. It is configured to be.

[0007] In order to prevent the gap between the connecting pipe and the inner pipe in the relatively extended state of the inner and outer pipes from rattling in the direction intersecting the axis of the pipe in the telescopic structure, the inner peripheral side of the connecting pipe at the base side is provided. It is desirable that a very short tubular spacer having a thickness substantially equal to the thickness of the outer tube be fixed to the surface. In that case, the connecting pin is inserted through the outer tube, the spacer and the inner tube. The spacer also acts as the base end of the slot. That is,
The elongated hole extends from a portion near the end face of the second bracket facing the base of the connecting pipe to the base end of the connecting pipe, but is closed by the spacer just before the end. In the above description, the `` base '' of the outer tube and the connecting tube refers to the portion facing the inner tube, and the `` base '' of the inner tube refers to the portion facing the outer tube and the connecting tube.

[0008] The above-mentioned connecting pin is stable both in a posture perpendicular to each tube and in a posture parallel to each tube. In addition, when the connection pin is inserted into the inner tube pin hole, "twisting" occurs. It is convenient for use if it is provided outside the connecting pipe by appropriate means so as not to occur. Further, the inner pipe may be a single pipe, but in order to accommodate the size of the gap between the formwork and the ground (or including the hardened concrete surface which has already been cast in the preceding work). The inner pipe itself can also have a telescopic double pipe structure. This is the same for the outer tube.

According to the present invention, the distance between the receiving plate at the tip of the inner tube and the seat plate at the tip of the outer tube is slightly longer than the distance between the mold and the ground. First, an operation of selecting an appropriate position from the plurality of pin holes of the inner tube and inserting and setting the connecting pin so as to reduce the size is performed first. Next, the support rod is positioned between the formwork and the ground, and the head of the long leg-shaped adjustment bolt is tightened using, for example, a torque wrench with a built-in ratchet mechanism. The frame is supported by the supporting rod without swinging to the ground.

[Advantage of the Invention] Since the expansion and contraction structure of the present invention is configured as described above, the adjustment bolt is located below the first bracket and is directly deposited on the thread of the bolt even if mortar or the like falls from above. Never. Even if the screw thread of the adjustment bolt is damaged, only the bolt needs to be replaced, and an increase in the construction cost for the supporting rod can be suppressed. And since the inner pipe can be expanded and contracted by turning the small bolt head with a torque wrench etc. compared to the outer pipe etc.
Formwork setting work can be performed efficiently even in narrow places. Furthermore, regardless of the degree of expansion or contraction, the outer pipe is sandwiched between the inner pipe and the connecting pipe to maintain the "triple pipe" structure. In comparison, the connection strength between the inner and outer pipes is remarkably improved.

1. A base of an inner pipe (30) having a receiving plate (31) attached to a tip thereof for supporting a concrete form (K) via a thick material (B), and a seat plate (14) provided at a tip. In the telescopic structure, the base is slidably fitted to the base of the attached outer tube (10), and both bases are connected to each other by a screw mechanism and a pin so that the base can be relatively expanded and contracted and the relative positional relationship is fixed. A plurality of pin holes (33) are drilled in the inner pipe (30) at appropriate intervals in the axial direction,
A connecting pin (40), which can be selectively set in the pin hole, is attached to the base side of the connecting pipe (20), and the connecting pipe (20) has an elongated hole ( At the base of the outer tube (10), which is slidably housed inside the connecting tube (20), a leg (52) of an adjusting bolt (50) is provided. Round hole (1
A first bracket (11) provided with 2) penetrates the elongated hole (23) and is mounted so as to protrude outward. The distal end of the connecting pipe (20) is attached in the same direction as the first bracket (11). 2nd bracket
