Description

  In the present invention, when a concrete structure is constructed, a water stop plate embedded in the joint portion of the concrete is suspended before a concrete is placed and supported to a reinforcing bar such as a water stop plate hanging tool. It relates to the fixing structure of objects.

  When fixing an object to a bar, various means are required as the fixing structure. For example, a concrete structure such as a reinforced concrete structure is constructed by first arranging a pair of frame plates in parallel to form a concrete formwork, and then placing concrete in the formwork. (See Patent Document 1 Fig. 1). At the time of construction, when concrete is placed in a superimposed manner, for example, as shown in FIG. 11, a water stop plate A is embedded in the joint portion of the concrete C, and the water stop plate A Prevents water from entering and passing through the joint interface. This water stop plate A needs to be supported and fixed at a required position before the concrete C is placed.

As shown in FIG. 11, as a supporting and fixing water stop plate hanging tool, there is a conventional one in which a horizontal member 2 is installed between the longitudinal bars 1, 1 and the horizontal member 2 is provided.
The water stop plate suspending tool 30 has an upper end portion of the piece-like main body 31 inserted into the horizontal member 2 and attached to a required position by a nut 32, and an inverted U-shaped gripping portion 33 is provided at the lower end portion. The upper edge of the water stop plate A is inserted into the grip portion 33 and the butterfly bolt 34 is screwed into the grip portion 33 to be supported and fixed. The water stop plate hanging tool 30 is provided at a required interval in the length direction of the water stop plate A (in FIG. 11, the front and rear oblique directions), and the water stop plate A is supported and fixed over the entire length of the interface of the joint portion. (See Patent Document 1 FIGS. 1 to 5).

Japanese Utility Model Publication No. 61-108758 JP-A-9-86086

  The above-described conventional water stop plate suspending tool 30 is attached to the horizontal member 2 by screwing of the nut 32, and the support fixing of the water stop plate A is also screwed by the butterfly bolt 34. The screwing of the nut 32 and the butterfly bolt 34 is cumbersome and takes a long time because it reduces workability.

  This invention makes it a subject to provide the fixing structure of the thing to reinforcing bars, such as a water stop board suspending tool which can suspend and support the water stop board A easily under the said actual condition.

In order to achieve the above object, according to the present invention, an object is fixed to a reinforcing bar by a double clip that can grasp the object with a simple operation.
That is, first, as shown in Patent Document 2 and the like, the double clip is a well-known one that has existed in the past, and by bending an elastic thin plate into a triangular cross-section, the double clip is separated from both ends of the back plate. A pair of opposing sandwiching plates that are extended are formed, a clip main body provided with a bearing portion and a tip edge sandwiching portion on each of the sandwiching plates, a metal wire bent into a substantially U shape, and both It consists of an open / close lever formed with a knob, an arm, and a rotary shaft by bending the tip end outward in the width direction, and the rotary shaft on the open / close lever rotates in the bearing on the clip body side. The structure inserted freely is common.
In this double clip, when the pair of open / close levers are raised and moved closer (gripped), the pair of clamping plates are opened (the leading edge clamping unit is opened), and a part of the object is put into the clip body through the opening. When the grip of the pair of opening / closing levers is released, the pair of sandwiching plates are closed to sandwich a part of the object, and the operation is general and easy.
For this reason, if an object is attached to a double clip, the object can be easily fixed to a reinforcing bar through the double clip.

Next, according to the present invention, a hole through which the reinforcing bar penetrates is formed in each of the pair of sandwiching plates of the double clip, and the periphery of the through hole comes into contact with the reinforcing bar by a force for closing the pair of sandwiching plates. The double clip was fixed to the rebar.
This action can be performed at an arbitrary position in the longitudinal direction of the reinforcing bar, and its fixing operation is easy. For this reason, the thing attached to the double click via a double clip can be easily fixed to the arbitrary positions of a reinforcing bar.

  The structure of the structure for fixing an object to a reinforcing bar according to the present invention is a structure having a double clip for fixing an object to a reinforcing bar, wherein the double clip is attached to the object, and the elastic thin plate has a triangular cross section. A clip body in which a back plate and a pair of opposing holding plates extending from both end edges of the back plate are formed by bending, and a bearing portion and a leading edge holding portion are provided on each of the holding plates; The clip comprises: a pair of opening and closing levers formed by bending a metal wire into a substantially U shape and further bending both ends thereof in the width direction to form a knob portion, an arm portion, and a rotating shaft portion. A pivot shaft on the opening / closing lever side is pivotally inserted into the bearing on the main body side, and a hole through which the reinforcing bar penetrates is formed in each sandwiching plate of the pair of double clips. It is possible to adopt a configuration in which the peripheral edge of the through hole by the force being closed is plates double clip in contact with the reinforcing bar is fixed to the reinforcing bar.

As a specific configuration of this configuration, the reinforcing bar is a horizontal support rod provided on the vertical bar, and the above-mentioned object is a water stop plate attached to the support rod, and the water stop plate is used as the support rod. A water stop plate hanging tool for fixing an object to the rebar to be supported by suspension, one double clip holding the upper edge of the water stop plate, and the other double clip attached to the support rod And a connecting rod for connecting the double clips, the double clips having the above-mentioned double clip configuration, and a hole through which the support rod passes is formed in the pair of holding plates of the other double clip. Thus, it is possible to adopt a configuration in which the periphery of the through hole is in contact with the support rod and the other double clip is fixed to the support rod by a force for closing the pair of sandwiching plates.
With this configuration, the operation of attaching the double clip to the horizontal member 2 serving as a support rod and the operation of grasping and supporting the water stop plate A are extremely easy.

In each of the above-described configurations, a support plate that extends outward from the open edge and then bends toward the back plate side is provided on one of the holding plates of the pair of the other double clips. A through hole of the same size on the same axis as the through hole of one of the sandwiching plates can be formed, and both the through holes can have the same size as the thickness of the support rod (rebar).
If comprised in this way, since the position with respect to the support rod (rebar) of a double clip is fixed by one clamping plate and support plate which the support rod (rebar) penetrated, the double clip will be with respect to the support rod (rebar) It is difficult to tilt, and the connecting rods of both double clips are also difficult to tilt with respect to the vertical direction, and can stably support objects such as a water stop plate.
The double clip may have a pair of open / close levers as in the general case, but if one of the double clips is also used as a connecting rod, the number of parts is reduced and the structure is also reduced. Smarter and cheaper.

  In the present invention, as described above, the horizontal member 2 and the water stop plate A are grasped and supported by the double clip, so that the suspension support operation of the water stop plate and the like is simple.

  1 to 4 show a water stop plate suspending tool as an embodiment according to the present invention, and this water stop plate suspending tool 10 is formed on a structural longitudinal bar 1 made of a deformed reinforcing bar or the like as in the prior art. Similarly, a horizontal non-structural support rod (the above-mentioned reinforcing steel horizontal member) 2 made of deformed reinforcing bars etc. is provided by tying it with a number line, etc., and is attached to the support rod 2 to support the water stop plate A by suspending it. There is one double clip 12 that holds the upper edge of the water stop plate A, the other double clip 11 that is attached to the support rod 2, and a connecting rod 13 that connects the double clips 11 and 12. The water stop plate A is made of rubber, vinyl chloride, a thin steel plate or the like, as in the conventional case, and the cross-sectional shape thereof is arbitrary as in the conventional case.

  The upper and lower clips 11, 12 have the same basic shape, and a pair of opposing sandwiching plates 15 a extending from the back plate 14 and both end edges of the back plate 14 by bending the elastic thin plate into a triangular cross section, 15b (generic symbol 15) is formed, a clip body 17 provided with a tip edge clamping portion 16 having a bearing portion 16a on each of the clamping plates 15, a metal wire is bent into a substantially U shape, It is composed of an opening / closing lever 18 having a knob 18a, an arm 18b, and a rotating shaft 18c formed by bending both distal ends outward in the width direction.

The connecting rod 13 is formed by punching an elastic thin plate, a metal wire or the like, has an H shape, and serves as one of the opening / closing levers of the clips 11 and 12. A rotation shaft portion 13c is formed. When the H-shaped arm portion 13b is appropriately bent in the middle (by making it a U-shape), when the following water stop plate A is suspended, the upper and lower clips 11, 12 are substantially on the same vertical line. Can be located.
The connecting shaft 13 and the opening / closing lever 13 can be raised and lowered with respect to the clip body 17 by inserting the rotating shaft portion 13 c of the connecting rod 13 and the rotating shaft portion 18 c of the opening / closing lever 18 into the bearing portion 16 a of the clip body 17. ing. The opening / closing lever 18 and the rotating shafts 18c, 13c of the connecting rod 13 may be bent inward in the width direction.

Holes 19a and 19b through which the support rod 2 passes are formed in a pair of holding plates 15 of the clip 11 attached to the upper support rod 2, respectively. Further, a support plate 20 that extends outward from its open edge and then bends toward the back plate 14 side is provided on one clamping plate 15a of the clip 11 by bending the same material. 20 also has a hole 21 through which the support rod 2 passes.
The one holding plate 15a and the through holes 19a, 21 of the support plate 20 have the same shape that is slightly larger than the cross-sectional shape of the support plate 20, and when the support rod 2 passes through both the through holes 19a, 21, The clip 11 is positioned with respect to the support rod 2 through both the through holes 19a and 21. That is, as shown in FIG. 4B, one clamping plate 15 a and the connecting rod 13 are fixed substantially perpendicular to the support rod 2.

  The through hole 19b of the other holding plate 15b has an elliptical shape that is long in the vertical direction. When the support rod 2 is passed through, the other holding plate 15b faces the one holding plate 15a through the through hole 19b. It can be moved by the elasticity of the elastic thin plate. Therefore, as shown in FIG. 4 (a), the support rod 2 is inserted through the one clamping plate 15a and the through holes 19a and 21 of the connecting rod 13, and further, as shown in FIG. 18 and the connecting rod 13 open both the clamping plates 15a and 15b, insert the support rod 2 into the other clamping plate 15b through the through hole 19b, and close both the clamping plates 15a and 15b. In the state where the connecting rod 13 is fixed substantially perpendicular to the support rod 2, the other holding plate 15b moves on the support rod 2, and finally comes into contact with the upper and lower edges of the inner periphery of the through hole 19b. Thus, the movement of the other clamping plate 15b is prevented, and the clip 11 is fixed to the support rod 2. The vertical length of the through-hole 19b is in contact with the inner peripheral upper and lower edges of the through-hole 19b when the both clamping plates 15a and 15b are closed, and the movement of the other clamping plate 15b is prevented by the contact. As appropriate, it is set by experiment or the like.

  The water stop plate suspending tool 10 of this embodiment has the above-described configuration. Next, the operation of the water stop plate suspending tool 10 will be described. It inserts in the support rod 2 of the installation upper position of the water stop plate A through the through-holes 19a, 19b, and 21. In this inserted (installed) state, the water stop plate A is suspended by the water stop plate hanging tool 10.

  First, the both holding plates 15a and 15b of the lower clip 12 are opened, and the upper edge of the water stop plate A is put into the both holding plates 15a and 15b and supported. Next, both the clamping plates 15a and 15b of the upper clip 11 are opened, and the clip 11 is moved so that the connecting rod 13 is substantially on the vertical line of the water stop plate A, and then both the clamping plates 15a and 15b. Close. Then, with one holding plate 15a and the connecting rod 13 of the clip 11 being fixed substantially perpendicularly to the support rod 2, the other holding plate 15b moves on the support rod 2, and eventually the through hole 19b. Abutting on the inner peripheral upper edge, the movement of the other clamping plate 15b is blocked by the abutment, and the clip 11 is fixed to the support rod 2. That is, the water stop plate A is supported by being suspended in the vertical direction by the water stop plate hanging tool 10. In this state, concrete C is placed.

  As in the conventional method, the concrete C is first placed up to the middle height of the water stop plate A (concrete joint portion) as shown in FIG. The water stop plate A is suspended and supported (attached) by the water stop plate hanging tool 10 at the position of the concrete joint on the horizontal portion after being added or assembled. Concrete C is further placed between the frames to form a vertical portion.

  As shown in FIG. 5, the support plate 20 can be omitted. In the water stop plate hanging tool 10 ′, when the clip 11 is fixed to the support rod 2, the clip 11 (connection rod) is caused by friction between the inner peripheral edge of the through-hole 19a of one clamping plate 15b and the support rod 2. 13) In order to maintain the vertical state of 13), the clip 11 may be inclined with respect to the support rod 2 due to the movement of the other clamping plate 15b, but this inclination is not enough for the suspension support of the water stop plate A. There is no effect.

  In the above-described embodiment, one opening / closing lever 18 is also used by the connecting rod 13, but as long as it does not get in the way, it can have a pair of opening / closing levers 18 like a general double clip. In this case, the end of the rolling bar 13 is fixed to the clamping piece 15 of the clip body 17 by welding or the like.

Although the said embodiment was the aspect which attaches the water stop board A to the support rod 2, this invention is employable for the various structures which fix (attach) an object to a reinforcing bar.
For example, in the placement of the concrete C, when placing the horizontal portion, the vertical portion, etc. and the concrete in an overlapping manner, the level plate indicating the placement top surface position can be adopted (fixed) to the reinforcing bar structure. .
As shown in FIGS. 6 to 10, the structure in which the level plate is attached to the vertical stripe 1 is such that, in the other double click 11, the support plate 20 is further extended and the extended portion is used as the level plate L.

  As shown in FIGS. 7 and 8, the double click 11 with the level plate L opens both sandwiching plates 15a and 15b and penetrates the clip 11 through the vertical bars 1 through the through holes 19a and 19b. After moving C to the upper limit position for placing, both the clamping plates 15a and 15b are closed. Then, similarly to the above, the periphery of the through-holes 19a, 19b is in contact with the vertical bars 1 due to the force of closing the pair of sandwiching plates 15a, 15b, and the double clip 11 is fixed to the vertical bars 1, The level plate L is fixed to the longitudinal bars 1.

At this time, as shown in FIG. 8, if the through hole 21 of the support plate 20 having the level plate L is made approximately the same as the diameter of the vertical bar 1, the level plate L is set to the vertical bar 1 as described above. It can be positioned at a right angle.
However, as shown in FIGS. 6 and 7, even when the through hole 21 ′ is larger than the diameter of the vertical bar 1, as described above, when the clip 11 is fixed to the vertical bar 1, In order to maintain the horizontal state of the clip 11 by friction between the inner peripheral edge of the through-hole 19a and the vertical bar 1, the clip 11 may be inclined with respect to the vertical bar 1 due to the movement of the other clamping plate 15b. The inclination is not so large that the height of the level plate L varies.

As shown in FIGS. 9 and 10, the level plate L may be extended to the opening / closing lever 18 side.
In the embodiment shown in FIG. 1, instead of the lower double clip 12, a clothespin-shaped gripping tool or the structure of the gripping portion 33 shown in FIG. 11 can be used.
Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
