The lock body 4 is removed from the support rope 2, the form panel 52 is removed from the concrete layer 10, and a surplus portion of the support rope 2 is cut.SELECTED DRAWING: Figure 1

Description

The present invention provides an interval between repaired objects, for example, when a formwork panel is arranged at a fixed interval with respect to the revetment in order to cover the damaged wall of the revetment with a concrete layer and repair it. The present invention relates to a repair panel support suitable for supporting a panel to be disposed and a repair method using the repair panel support.

For example, the quay of a harbor and the wall of a revetment are gradually eroded or damaged by aging, wave power, or collision of ice blocks, and a part of the wall is beaten. If this state is left unattended, there is a risk that the quay will collapse, or the road will collapse and the car will fall. Therefore, in order to repair the eroded or damaged wall surface, it is necessary to perform a construction for covering the wall surface with a concrete layer.
FIG. 6 shows a repair method of the prior art. In order to support the formwork panel 52 at regular intervals facing the repair wall 51A of the revetment 51, a plurality of drills are inserted into the repair wall 51A at appropriate intervals. A metal support rod 53 having at least a base end side 53A and having a thread groove formed therein is drilled, and the distal end side 53B is inserted into the insertion hole 51B and fixed with mortar. Measuring the distance from the repair wall 51A, a support nut 53 is screwed with a receiving nut 54 as a mold receiving member to support the mold panel 52, and a fastening nut 55 that supports the mold panel 52 is externally screwed. Then, by holding the form panel 52 at a constant interval, a space is formed between the repair wall surface 51A by a metal like a so-called separator, and concrete is placed in the space to form a concrete layer 56. It is something to repair with.

Not found.

  In the above-described method of supporting the formwork panel 52 with the metal support bar 53, the support bar 53 inserted into the repair wall surface 51A remains embedded in the concrete layer 56, so the problem of explosion of the concrete layer 56 due to rusting. It takes a lot of time to fasten the receiving nut 54 to the support bar 53 while adjusting the distance from the repair wall surface 51A. It is dangerous because the extra part of the support bar 53 protrudes from the concrete layer 56. Since most of the portions are extended in the lateral direction along the repair wall surface 51A, it is necessary to transfer the formwork panel 52 to each repair portion having a certain width, which increases the construction cost and requires a long construction period. There are a number of drawbacks.

  The present invention has been made in view of the above-mentioned drawbacks of the prior art, and since it does not use any metal material, there is no explosion of the concrete structure due to rusting, and the overall weight can be reduced, so it is excellent in workability. An object of the present invention is to provide a repair panel support that is excellent in strength because the concrete layer is securely attached to the repair wall and a repair method using the repair panel support.

The means of the present invention according to claim 1 configured to solve the above-mentioned problem is fixed to a support rope composed of a non-rusting fiber bundle having tensile strength and severability and to one end side of the support rope. A support shaft made of a non-rusting material that is inserted into and fixed to the repaired object, and a panel that is inserted into a panel disposed opposite to the repaired object and extends to the outer surface side of the panel. A concrete layer formed by filling mortar into a concrete filling space formed by supporting the panel to the repaired object at predetermined intervals with respect to the repair object. After the molding, the locking body is removed from the support rope, and the panel is removed from the concrete layer.

  And the said support rope is good to provide one or more concrete latching blocks in the middle of the longitudinal direction.

  Moreover, it is good for the said support rope to cut | disconnect a surplus part after removing the said panel from the said concrete layer.

  Moreover, it is good to provide the wire for a lead for inserting in the said panel at the other end side of the said support rope.

  Further, the locking body is provided with a support rope insertion hole penetrating in the axial direction substantially at the center of the shaft body, and the wedge insertion with a taper taper from the base end side toward the tip end side along the support rope insertion hole. A synthetic resin locking main body having a configuration in which a hole is provided and having a front end surface serving as a panel contact surface, and a wedge for press-fitting the support rope to the locking main body by press-fitting into the wedge insertion hole It is good to comprise.

  The wedge may have a shape in which an insertion / removal projection is formed on the base end side.

  The wedge may be connected to the locking body by a connecting material.

Further, the means constituting the present invention according to claim 8 is a method of inserting and fixing a support body provided on one end side of a support rope made of a non-rusting fiber bundle having tensile strength and severability to a repaired object, The other end side of the support rope is inserted into a panel disposed opposite to the repaired object, and a locking body is detachably attached to the other end side of the support rope extending outside the panel in contact with the panel. By providing the support, the panel is supported at a predetermined interval to form a mortar filling space, filling the mortar filling space with mortar and solidifying the concrete layer, and then forming the locking body. The support rope is removed, the panel is removed from the concrete layer, and the remaining portion of the support rope extending from the concrete layer is cut.

(1) Panels are supported at fixed intervals with respect to the repaired object by a support rope composed of a bundle of non-rusting fibers having tensile strength and severability and a non-rusting anchoring body, and a mortar is formed in the space formed. Since the concrete layer is formed by filling the concrete layer, there is no explosion of the concrete layer due to rusting, and a highly durable concrete layer can be formed on the repair surface.
(2) Since the support rope is provided with one or more concrete locking blocks in the middle in the longitudinal direction, the concrete layer can be supported more firmly.
(3) Since the support rope cuts the extra part after the concrete layer is formed, the scenery is not damaged, fishing lines are not entangled, and it does not become an obstacle to a ship to come and go.
(4) Since the lead wire for inserting into the insertion hole of the panel is provided on the other end side of the support rope, the support rope can be easily and quickly inserted into the insertion hole of the panel, so that the workability is excellent.
(5) Since the support cable inserted into the panel is configured to fix the locking body with the wedge, the operation of supporting the panel can be easily and quickly performed, and the operation of removing the locking body from the support cable is also possible. Since it can be performed easily, it is excellent in workability.
(6) Since the wedge has a protrusion for insertion / removal formed on the base end side, the work of press-fitting into the locking main body and the work of pulling out the reverse can be reliably and efficiently performed.
(7) Since the wedge is connected to the locking main body by the connecting material, it is possible to reliably prevent a situation where the wedge is lost during transportation or a situation where the wedge is dropped during the work, so that cost reduction and workability can be improved.
