Description

  The present invention relates to an anchor bolt support, and in particular, when a concrete foundation is constructed using a formwork, the anchor bolt is supported until the concrete placed over a pair of formwork is hardened. The present invention relates to an anchor bolt support.

  Anchor bolts for fixing structural members are embedded in the concrete foundation of the building structure. The anchor bolt is positioned and held at an arbitrary position before placing concrete. As means for holding the anchor bolt, for example, an anchor bolt support 50 shown in FIG. 4A is known (for example, Patent Document 1). The anchor bolt support 50 includes a plate-like support plate 51 that is arranged across a pair of molds 60 that are arranged to face each other, and a holder that is provided at the center portion of the support plate 51 and holds the anchor bolt B. A portion 52 and a plate support 56 for fixing both end sides of the support plate 51 to the mold 60 are configured. The holding portion 52 includes a cylindrical support tube portion 53 having an insertion hole 53a through which the anchor bolt B can be inserted, and a fixing screw 54 screwed in a radial direction at a substantially central portion in the height direction of the support tube portion 53. It has. That is, the anchor bolt B can be pressed and fixed by inserting the anchor bolt B into the insertion hole 53a of the support cylinder portion 53 and then tightening the fixing screw 54.

  However, according to the anchor bolt support 50 described above, the anchor bolt B that is elongated in the vertical direction must be inserted into the insertion hole 53a of the support cylinder portion 53 from below the support plate 51 in the mold 60. First, it took time to assemble. More specifically, the anchor bolt B is generally bent at the lower end portion so as to increase the pulling strength and is L-shaped or J-shaped. Therefore, the anchor bolt B is inserted into the insertion hole 53a of the support cylinder portion 53. At this time, the anchor bolt B must be inserted from the lower opening of the support cylinder 53, and as a result, it is inserted in a place where it is difficult to see, and in the narrow formwork 60, and workability is deteriorated. It was. Further, when the anchor bolt B is moved below the support cylinder portion 53, the lower end of the anchor bolt B may come into contact with the base portion (not shown) of the concrete foundation. According to this, the plate support 56 is removed. The support plate 51 had to be lifted once, and the poor workability was promoted.

  On the other hand, an anchor bolt support 70 as shown in FIG. 4B is also known in order to eliminate the above-described problems (for example, Patent Document 2). In the anchor bolt support 70, a holding portion 72 is provided at the center portion of the support plate 71. The holding portion 72 includes a positioning portion 73 that is positioned by contacting the upper and lower portions of the outer peripheral surface of the anchor bolt B, and a support wall portion 74 that faces the positioning portion 73 and has a screw hole (not shown). And a fixing screw 75 that is screwed into the screw hole and presses and fixes the anchor bolt B by a tightening operation. According to the anchor bolt support tool 70, the anchor bolt B can be inserted from the gap between the positioning portion 73 and the support wall portion 74, that is, the groove-shaped notch 76 opened to the side. The fitting operation of B becomes easy, and the anchor bolt B can be disposed without lifting the support plate 71, so that the workability can be improved.

  However, according to the anchor bolt support tool 70 described above, the anchor bolt B is supported only at a total of three points, that is, the upper and lower two contact points in the positioning portion 73 and the tip of the fixing screw 75, and these Since these three points are all located on the same vertical plane, the support of the anchor bolt B may be unstable, that is, the anchor bolt B may be displaced in a direction deviating from the vertical plane. It was. In order to regulate the displacement of the anchor bolt B, it is possible to form a recess 73a in the positioning portion 73 as shown by a two-dot chain line in FIG. 4B. When the anchor bolt B is inserted into the recess 73a or when the anchor bolt B is relatively removed from the recess 73a when removing the anchor bolt support 70, the anchor bolt B is moved in the axial direction of the fixing screw 75. As a result, the axial displacement amount of the fixing screw 75 becomes long, and a lot of time is required for the tightening operation and the detaching operation.

  Further, since the anchor bolt B is supported at three points, the anchor bolt B must be disposed so that the upper end of the anchor bolt B is positioned at least above the positioning portion 73 on the upper side, and thus the height of the anchor bolt B is increased. The height cannot be set at a low position (for example, the upper end of the anchor bolt B slightly protrudes from the support plate 71), which is inconvenient. As the height of the positioning part 73 on the upper side is lowered, the lower limit position of the anchor bolt B can be lowered, that is, the degree of freedom in the height of the anchor bolt B can be increased. Since the contact point of the upper positioning portion 73 approaches the tip of the fixing screw 75, the support state of the anchor bolt B becomes further unstable.

  Further, since the anchor bolt B is pressed and fixed at the tip of the fixing screw 75, it becomes difficult to generate a large holding force, and the anchor bolt B is lowered (or dropped) by its own weight even though it is held. There was concern. Furthermore, when the fixing screw 75 is tightened too strongly, the peripheral surface of the anchor bolt B is damaged or deformed by the concentrated pressing force applied to the anchor bolt B, or the support for supporting the fixing screw 75 is performed. The wall 74 may be deformed.

  In view of the above, the present invention has an object to provide an anchor bolt support that can improve the workability when supporting an anchor bolt and can support the anchor bolt in a stable state. Is.

The anchor bolt support of the present invention is
"A support plate that is supported in a state of being stretched over a pair of molds,
A notch formed in the support plate and capable of inserting an anchor bolt from the side;
An abutting portion that is formed along an inner edge of the notch portion, is erected from an upper surface of the support plate, and is capable of abutting on the anchor bolt inserted into the notch portion;
An annular surrounding portion that surrounds the anchor bolt and the contact portion in a face-to-face state, and a bundling member that has a screw portion that reduces the space surrounded by the surrounding portion by tightening operation. ''
It is characterized by this.

  Here, the shape of the “anchor bolt” is not particularly limited. For example, the anchor bolt can be applied to an anchor bolt whose lower end portion is bent and has an L shape or a J shape as a whole. The “contact portion” may be formed integrally with the support plate, but may be formed as a separate member and integrally formed by welding or bonding to the upper surface of the support plate.

  According to the anchor bolt support of the present invention, the anchor bolt is supported with respect to the support plate that spans the upper surfaces of the pair of molds. More specifically, the support plate is formed with a notch that opens to the side, and a bar-shaped anchor bolt that is long in the vertical direction extends from the side opening to the inside of the notch so as to intersect the support plate. (Ie, inside the support plate). By enabling the anchor bolt to be inserted from the side in this way, for example, even an anchor bolt having an overall L shape or J shape can be inserted very easily. Further, the anchor bolt can be arranged at an arbitrary position without the lower end of the anchor bolt contacting the base portion of the concrete foundation and without lifting the support plate.

  In addition, since the abutment portion formed along the inner edge of the notch portion is erected on the upper surface of the support plate, when the anchor bolt is inserted horizontally to the depth of the notch portion, the outer peripheral surface of the anchor bolt is The anchor bolt hits the contact portion and is positioned. The anchor bolt thus positioned is held by the binding member. More specifically, since the bundling member is provided with an annular surrounding portion, if the surrounding portion is fitted from above the anchor bolt in a state where the anchor bolt and the abutting portion abut each other, The contact portion is surrounded by an annular surrounding portion. When the operation screw portion provided on the binding member is tightened, the space surrounded by the surrounding portion is reduced, and the anchor bolt and the contact portion are bound. That is, the anchor bolt is fixed to the support plate.

  Thus, by using the binding member, the anchor bolt is sandwiched by the surrounding portion of the binding member together with the contact portion, and is supported by a plurality of surfaces or a plurality of lines. Therefore, it is possible to increase the stability of the anchor bolt, increase the holding force, and suppress the anchor bolt or the like from being damaged due to the fall of the anchor bolt due to its own weight or excessive tightening. In addition, although the surrounding part of the binding member is formed in an annular shape, it is inserted from the upper end side of the anchor bolt, so that it is visible and works in a relatively large space, increasing the burden on the operator. There is nothing.

In the anchor bolt support of the present invention,
“The notch has a triangular shape with the open side as the base, and the abutting portion is made of a wall-like member having a V-shape in plan view.”
It is good also as a structure.

  According to the anchor bolt support of the present invention, the shape of the notch formed in the support plate is a triangle with the open side as the base (that is, the shape of the inner edge of the notch is V-shaped). It is possible to widen the insertion opening and guide the anchor bolt toward the center of the notch. Therefore, the operation of inserting the anchor bolt into the notch can be further simplified. Further, the abutment portion is made of a wall-shaped member (a member having a height) having a V-shape in plan view (cross-sectional shape), and the support portion of the anchor bolt is made of a bar having a circular cross-sectional shape. Therefore, regardless of the diameter of the anchor bolt, the outer peripheral surface of the anchor bolt and the abutting portion can be brought into line contact in two directions in the vertical direction, and the stability of the anchor bolt can be further enhanced. Further, by forming the abutting portion in a V shape, the strength of the abutting portion can be increased and deformation and the like can be suppressed. If the vertical width of the surrounding portion of the bundling member is formed to be relatively large (for example, if it matches the height of the contact portion), the stability of the anchor bolt can be greatly increased.

Furthermore, in the anchor bolt support of the present invention,
“The abutting portion is formed only with respect to the tip portion of the notch portion,
When the anchor bolt is abutted against the contact portion, at least a part of the anchor bolt protrudes from the space between the contact portions.
You may comprise as follows.

  According to this, in a state where the anchor bolt is abutted against the contact portion, a part of the anchor bolt (a portion on the side opposite to the contact portion) protrudes from the space surrounded by the V-shaped contact portion. The surrounding portion of the binding member can be brought into direct contact with the outer peripheral surface of the anchor bolt. Therefore, even when the contact portion is formed in a V shape, the surrounding portion can be brought into direct contact with at least a part of the anchor bolt, and a force is applied so that the anchor bolt and the contact portion are in pressure contact with each other. Is possible.

  As described above, according to the present invention, since the notch portion is formed in the support plate, for example, even an L-shaped or J-shaped anchor bolt can be inserted very easily. Further, since the surrounding portion of the binding member is inserted from the upper end side of the anchor bolt, the work can be visually recognized by a worker and the work is performed in a relatively wide space, and the workability can be greatly improved. In addition, since the anchor bolt is clamped by the bundling member together with the contact portion, the anchor bolt can be supported in a stable state, and the holding force can be increased, so that the anchor bolt can be dropped or excessively moved. It is possible to suppress breakage due to the tightening. Furthermore, since the anchor bolt can be held even when the anchor bolt is disposed at a relatively low position, the height at which the anchor bolt can be installed can be widened, and the usability can be improved.

It is the perspective view which looked at the anchor bolt support of this embodiment from diagonally forward. It is the disassembled perspective view which decomposed | disassembled the anchor bolt support tool and was seen from diagonally forward. It is a conceptual diagram which shows the usage method in an anchor bolt support tool. (A) is a perspective view which shows a 1st prior art, (b) is a perspective view which shows a 2nd prior art.

  Hereinafter, the anchor bolt support 1 which is embodiment of this invention is demonstrated. As shown in FIG. 1, the anchor bolt support 1 supports the anchor bolt B until the cast concrete is hardened when a concrete foundation is constructed using the mold 60, and a pair of molds is used. A support plate 2 spanning the frame 60; a holding means 3 for holding the anchor bolt B with respect to the support plate 2; and a plate fixing means 4 for fixing both ends of the support plate 2 to the mold frame 60. Configured. In addition, the mold 60 includes a standing main body wall portion 61, a top plate portion 62 extending outward in the horizontal direction from the upper end of the main body wall portion 61, and a folded portion 63 suspended from the outer edge of the top plate portion 62. By arranging the pair of molds 60 so that the main body wall portions 61 face each other, a space for pouring concrete is formed between the pair of molds 60. ing.

  As shown in FIG. 2, the support plate 2 is made of a metal plate-like member, and a notch 6 is formed in the center portion in the bridging direction (longitudinal direction). The notch 6 has a triangular shape that opens on one side and has the open side as a base. The size of the open side of the notch 6 is larger than the diameter of the anchor bolt B, and the anchor bolt B can be inserted into the support plate 2 from the side.

  The holding means 3 will be described in detail. As shown in FIG. 2, the holding means 3 includes a contact portion 7 that can contact the anchor bolt B inserted into the notch portion 6, and a bundle that binds the anchor bolt B and the contact portion 7 in a state of abutting each other. And a member 8. The abutting part 7 is formed along the inner edge of the notch part 6 and is erected from the upper surface of the support plate 2. By inserting the anchor bolt B to the back side of the notch part 6, the abutting part is formed. 7 can be brought into contact. The contact portion 7 is made of a wall-like member having a V-shaped plan view (cross-sectional shape), and is fixed to the upper surface of the support plate 2 by welding. Further, the abutting portion 7 is disposed only with respect to the tip portion of the notch portion 6, and when the anchor bolt B abuts, substantially half of the anchor bolt B is surrounded by the V-shaped abutting portion 7. It is provided so as to protrude from the remaining space (see FIG. 3B). The height of the contact portion 7 is not particularly limited, but is set to 25 mm in this example.

  On the other hand, the bundling member 8 has a frame member 9 in which the tip end portion 9a is arcuate and the other portion is flat, and an arc shape arranged inside the frame member 9 so as to face the tip portion 9a. And a fixing bolt 11 screwed through the base side of the frame member 9 and having an axially leading end portion rotatably connected to the pressing piece 10. That is, when the fixing bolt 11 is tightened by holding the knob portion 11 a of the fixing bolt 11, the pressing piece 10 can be moved toward the distal end portion 9 a of the frame member 9 without rotating. That is, an annular surrounding portion is constituted by the tip portion 9 a of the arc-shaped frame member 9 and the pressing piece 10, and the fixing bolt 11 is operated to operate the tip portion 9 a of the frame member 9 and the pressing piece 10. It is possible to reduce the interval. Note that the height of the frame member 9 and the pressing piece 10 is equal to the height of the contact portion 7 protruding from the upper surface of the support plate 2, and the front end portion 9 a of the frame member 9 before the tightening operation is pressed. The distance from the piece 10 is larger than the length of the diameter of the anchor bolt B plus the thickness of the contact portion 7. Since the bundling member 8 of this example has the same configuration as that of a bundling tool (so-called “hose band”) used when connecting a hose to a water supply pipe, a commercially available hose band can also be used. is there. Here, the fixing bolt 11 corresponds to the screw portion of the present invention.

  Subsequently, the plate fixing means 4 will be described in detail. As shown in FIGS. 1 and 2, the plate fixing means 4 supports the support plate 2 spanned between a pair of molds 60, and is an attachment member 15 formed by bending a metal plate material. And a mounting bolt 16 and a supporting bolt 17 made of a thumbscrew. The mounting member 15 is suspended from the flat base portion 18 placed on the top plate portion 62 of the mold 60 and the inner end portion of the base portion 18, and is hooked on the upper inner surface of the main body wall portion 61. An inner support portion 19, an outer support piece 20 that hangs down from an outer end portion of the base portion 18 and faces the turned-up portion 63, and a standing piece 21 that is erected from one side end portion of the base portion 18. The upper support piece 22 extends horizontally from the upper end of the standing piece 21 and is positioned above the base portion 18. A first screw hole 23 formed through the outer support piece 20 is provided at the center position of the outer support piece 20, and the mounting bolt 16 is orthogonal to the main body wall portion 61 of the mold 60. It can be screwed in the direction. Further, a second screw hole 24 formed through the upper support piece 22 is provided at a position closer to the tip than the center of the upper support piece 22, and the support bolt 17 is parallel to the main body wall 61. It can be screwed in any direction.

  Further, the base portion 18 includes an extending portion 25 that extends in a straight horizontal direction from the central portion of the inner end portion, and both side end portions of the extending portion 25 are provided as inner latching portions 19. A pair of bent pieces 26 are formed to be bent downward. That is, at the inner front end portion of the base portion 18, it is cut in the width direction leaving the extending portion 25, and then a pair of bent pieces 26 are formed by bending both sides of the extending portion 25 downward. Thus, the inner end face of each bent piece 26 can be brought into contact with the main body wall 61.

  Next, a method for using the anchor bolt support 1 will be described with reference to FIGS. 1 to 3. First, the attachment members 15 are attached to the pair of molds 60, respectively. Specifically, the plate-like base portion 18 is placed on the top plate portion 62 of the mold 60 so that the inner latching portion 19 faces the inside of the mold 60. Then, the inner latching portion 19 hanging from the inner end portion of the base portion 18 is hooked on the main body wall portion 61 of the mold frame 60, and the outer support piece 20 hanging from the outer end portion of the base portion 3 becomes the mold frame. It will be in the state facing 60 folding | turning part 63. FIG. Thereafter, when the mounting bolt 16 screwed into the first screw hole 23 of the outer support piece 20 is tightened, the tip of the mounting bolt 16 comes into pressure contact with the folded portion 63, and the mounting member 15 is fixed to the mold frame 60. The

  Thereafter, the end portions of the support plate 2 are supported with respect to the pair of left and right mounting members 15 fixed to the respective molds 60. Specifically, the support plate 2 is inserted between the base portion 18 and the upper support piece 22 in the attachment member 15. The base 18 and the upper support piece 22 are connected via the standing piece 21, but the standing piece 21 is connected only to one end side of the upper support piece 22, and the relative side of the standing piece 21 is opened. Therefore, the end side of the support plate 2 can be inserted from the open side.

  After both ends of the support plate 2 are inserted into the pair of attachment members 15, the support bolts 17 screwed into the second screw holes 24 of the upper support piece 22 are tightened. Then, the tip of the support bolt 17 comes into pressure contact with the upper surface of the support plate 2, and the support plate 2 is fixed to the mounting member 15. That is, both ends of the support plate 2 are supported with respect to the pair of molds 60.

  Subsequently, the anchor bolt B is attached to the support plate 2. Specifically, as shown in FIGS. 3A and 3B, the anchor bolt B is anchored from the side opening portion of the support plate 2 to the inside of the cutout portion 6 so as to intersect the support plate 2. Insert bolt B in the horizontal direction. In addition, since the notch part 6 is exhibiting the triangular shape which makes an open | release side a base, it can guide toward the back | inner side of the notch part 6 while widening the insertion opening | mouth of the anchor bolt B. FIG. And if the anchor bolt B is inserted to the back side of the notch part 6, the outer peripheral surface of the anchor bolt B will contact | abut to the contact part 7, and the anchor bolt B will be in the state positioned. In particular, the abutting portion 7 has a V shape in plan view, and the support portion of the anchor bolt B has a circular cross-sectional shape, so that the outer peripheral surface of the anchor bolt B is not affected by the diameter of the anchor bolt B. It will be in line contact with the contact portion 7 at two locations, and the anchor bolt B is restricted from both moving in the longitudinal direction of the support plate 2 and moving in the width direction.

  Next, the positioned anchor bolt B is held by the binding member 8. That is, as shown in FIG. 3C, the anchor bolt B and the contact portion 7 are inserted between the tip portion 9 a (arc-shaped portion) of the frame member 9 and the pressing piece 10 in the binding member 8. Thus, the binding member 8 is fitted from above the anchor bolt B. According to this, the pressing piece 10 can be brought into contact with the back side of the contact portion 7, and the tip end portion 9 a of the frame member 9 can be brought into contact with the outer peripheral surface of the anchor bolt B. Thereafter, the fixing bolt 11 provided on the binding member 8 is tightened. Then, the distance between the tip portion 9a of the frame member 9 and the pressing piece 10 is shortened, and the anchor bolt B and the contact portion 7 are sandwiched, that is, the anchor bolt B is fixed to the support plate 2. It becomes a state.

  Thus, according to the anchor bolt support 1 of this example, since the notch 6 is formed in the support plate 2, the anchor bolt B can be inserted very easily regardless of the type of the anchor bolt B. it can. In addition, the work is performed in a relatively large space that is visible from above, and the workability can be greatly improved.

  Further, according to the anchor bolt support 1 of the present example, the anchor bolt B and the abutting portion 7 are sandwiched between the distal end portion 9a of the frame member 9 and the pressing piece 10, so that the anchor bolt B is in a stable state. In addition to being able to support it, it is possible to increase the holding force and to suppress damage due to dropping or excessive tightening of the anchor bolt B. Further, the anchor bolt B can be held even at a relatively low position, and the usability can be further enhanced.

  Moreover, according to the anchor bolt support 1 of this example, since the contact part 7 consists of a V-shaped wall-shaped member, it is two places with respect to the anchor bolt B irrespective of the magnitude | size of the diameter of the anchor bolt B. Line contact is possible, and the stability of the anchor bolt B can be further enhanced. Further, the strength of the contact portion 7 is increased, and damage to the contact portion 7 can be suppressed.

  Further, according to the anchor bolt support 1 of the present example, the anchor bolt B protrudes from the space surrounded by the V-shaped contact portion 7, so that the outer peripheral surface of the anchor bolt B is placed at the tip of the frame member 9. The portion 9a can be brought into direct contact, and as a result, the anchor bolt B and the contact portion 7 can be reliably brought into pressure contact.

  Further, according to the anchor bolt support 1 of the present example, the knob portion 11a of the fixing bolt 11 protrudes outward in the width direction of the support plate 2 (see FIG. 3C). Even when the height is close to the support plate 2, the knob portion 11 a can be operated without interfering with the support plate 2. Therefore, the attaching operation of the binding member 8 is further facilitated.

  Furthermore, according to the anchor bolt support 1 of this example, the binding member 8 is inserted from above with the anchor bolt B butted against the contact portion 7, so the axial displacement amount of the fixing bolt 11 is shortened. Therefore, it is possible to shorten the work time in the tightening operation and the detaching operation.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the said embodiment, although what provided the attachment member 15 was shown as a means to support the support plate 2 to the formwork 60, it hold | maintains with the plate support tool 56 which consists of a clamp member as shown in FIG. 4, or a magnet.
