Description

The present invention relates to an anchor ruler.

Buildings such as houses are installed on the ground via foundations. Such foundations have at least a rise to support the building above the ground. Anchor bolts for fixing the building to the foundation are buried in this rising part.

The rising part of the foundation is formed by placing concrete inside the formwork. Anchor bolts are integrally embedded in the rising part by placing concrete inside the formwork in a state of being disposed inside the formwork.

Anchor rulers are used to bury the anchor bolts in the correct position with respect to the rising edge. The anchor ruler is used by installing it on the top of the formwork.

At this time, the formwork has an outer formwork and an inner formwork, and the conventional anchor ruler straddles the upper parts of both the outer formwork and the inner formwork (outer formwork and inner formwork). It had a double-track shape having two parallel line portions so as to be installed at the same time (see, for example, Patent Documents 1 to 3).

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 18 are for explaining this embodiment.

<Structure> Hereinafter, the configuration of this embodiment will be described.

As shown in FIG. 1, a building 1 such as a house is installed on the ground 2 via a foundation 3. Such a foundation 3 has at least a rising portion 4 for supporting the building 1 at a position higher than the ground 2. Anchor bolts 5 (FIG. 2) for fixing the building 1 to the foundation 3 are embedded in the rising portion 4.

Here, the building 1 may have any structure, but in this embodiment, it is a unit building. The unit building is a building 1 that can be constructed in a short period of time by transporting a building unit 6 manufactured in advance at a factory to a construction site and assembling it on a foundation 3 at the construction site. The building unit 6 has a substantially rectangular parallelepiped shape and can be appropriately combined in the horizontal direction and the vertical direction. It is preferable to use building units 6 having the same size, but it is also possible to use a combination of building units of different sizes. In this embodiment, the building 1 has four building units 6 of the same size arranged side by side in the short side direction of the building unit 6. However, the arrangement and the number of building units 6 in the building 1 are not limited to this.

There are steel-framed and wood-based building units 6, and as shown in FIG. 3, the steel-framed building unit 6 has four pillars 7 on its skeleton. It has a unit frame with a box rigid frame structure in which the upper ends are connected in a rectangular shape by four ceiling beams 8 and the lower ends of the four pillars 7 are connected in a rectangular shape by four floor beams 9. ..

The ground 2 is the site on which the building 1 is constructed. As shown in FIG. 2, the foundation 3 has a rising portion 4 (outer peripheral rising portion) extending along the outer peripheral portion of the building 1 and a slab portion 11 provided so as to cover the ground 2 inside the rising portion 4. There are a solid foundation and a cloth foundation having only a rising portion 4 and no slab portion 11, but in this embodiment, the solid foundation is used. The solid foundation of this embodiment has, for example, a simple structure having an outer peripheral rising portion and a slab portion 11 and no other rising portion 4 (inner rising portion) inside the outer peripheral rising portion. There is. As for the inside of the outer peripheral rising portion, concrete or steel bundle members 12a and 12b are appropriately installed on the slab portion 11 so as to support the floor beam 9 of the building unit 6 from below. However, an inner rising portion may be provided integrally with the slab portion 11 on the outer peripheral rising portion or the inside of the slab portion 11.

The rising portion 4 is a vertical frame portion for supporting the building 1 at a position higher than the ground 2. The rising portion 4 has a required width and is provided so as to extend continuously. The upper end surface (top end) of the rising portion 4 is formed horizontally. In the case of this embodiment, the rising portion 4 is an outer peripheral rising portion continuously provided along the outer peripheral portion of the building 1.

The anchor bolt 5 is a bolt that is provided so as to project upward from the upper end surface of the rising portion 4 and extends in the vertical direction for fixing the lower portion of the building 1. In the case of a unit building, the anchor bolts 5 fix the lower end of the pillar 7 of the building unit 6, the floor beam 9, and the like. In this embodiment, the anchor bolt 5 is adapted to fix the vicinity of the end portion of the floor beam 9 located in the vicinity of the pillar 7.

The rising portion 4 of the foundation 3 is formed by placing concrete 14 inside the formwork 13 as shown in FIG. 4 (to FIG. 6). Anchor bolts 5 are integrally embedded in the rising portion 4 by placing concrete 14 inside the formwork 13 in a state of being arranged in advance inside the formwork 13. If necessary, the portion of the ground 2 where the foundation 3 is provided may be dug down to a required depth, and discarded concrete 2a or the like may be placed (FIG. 6).

Then, an anchor ruler 15 is used as necessary to bury the anchor bolt 5 in an accurate position with respect to the rising portion 4. The anchor ruler 15 is mainly composed of a ruler main body 17 installed on the upper portion 16 of the formwork 13 forming the rising portion 4. The upper portion 16 of the formwork 13 is a horizontal and flat surface having a uniform width extending in a band shape along the upper edge portion of the formwork 13. By installing the ruler body 17 on the upper portion 16 of the formwork 13, the ruler body 17 indicates the correct position of the anchor bolt 5 to be embedded in the rising portion 4 (or the exact position is specified). When the anchor ruler 15 is not used, the buried position of the anchor bolt 5 is measured one by one by a measure, which is troublesome and causes an error.

Here, the anchor ruler 15 of this embodiment is not composed of only one ruler main body 17, but as shown in FIG. 4, a plurality of types of ruler main bodies 17, auxiliary members as described later, and the like are used. Are used as a set, and these are appropriately combined according to the shape and size of the rising portion 4 (for example, so as to be continuously installed along the upper portion 16 of the mold 13). do. The ruler main body 17 and auxiliary members are formed by processing a metal plate having a required wall thickness into a required shape. For convenience of explanation, a specific ruler main body 17 may be referred to as an anchor ruler 15.

In contrast to the above basic configuration, in this embodiment, the following configuration can be provided.

(1) As shown in FIG.
The formwork 13 has an outer formwork 21 and an inner formwork 22.
In the anchor ruler 15 of this embodiment, the ruler main body 17 has a single wire shape installed along the upper portion 16 of the outer form 21.

Here, the outer formwork 21 is a frame member installed at a position outside the rising portion 4 of the formwork 13, and is continuously installed along the position of the rising portion 4. The upper portion 16 of the outer formwork 21 is a flange portion or the like extending from the upper edge portion of the outer formwork 21 to the side opposite to the inner formwork 22 (outside of the building 1), and is formed from the upper end surface of the rising portion 4. Is also installed in a high position.

As shown in FIG. 6 (FIG. 7), the upper end side portion of the outer form 21 is obliquely supported from the outside to the ground 2 by a support metal fitting called a supporter 25. A plurality of supporters 25 are installed along the outer formwork 21 with a required interval. Further, the outer form 21 is supported on the lower end side portion from below to the ground 2 with a required distance by a support tool called a half suspension width stopper 26 or the like.

The inner formwork 22 is a frame member installed at a position inside the rising portion 4 of the formwork 13, and is continuously installed along the position of the rising portion 4. The upper portion 16 of the inner formwork 22 is a flange portion or the like extending from the upper edge portion of the inner formwork 22 to the opposite side of the outer formwork 21 (inside the building 1), and is formed from the upper end surface of the rising portion 4. Is installed at a high position and at almost the same height as the upper portion 16 of the outer form 21. The inner formwork 22 is generally installed in parallel with the outer formwork 21 with an interval equal to the width dimension 27 of the rising portion 4 with respect to the outer formwork 21. In this case, the outer formwork 21 forms the outer surface of the rising portion 4, and the inner formwork 22 forms the inner surface of the rising portion 4. In this embodiment, the inner formwork 22 and the outer formwork 21 are installed at a distance wider than the width dimension 27 of the rising portion 4.

For example, when the foundation 3 is driven once (the rising portion 4 and the slab portion 11 are driven at once), the inner formwork 22 may have, for example, as shown in FIG. 7, an upper separator 28a, an intermediate separator 28b, or the like. By the spacing setting member (separator) of, for example, the outer mold 21 is installed in a state of maintaining the above-mentioned spacing.

The upper separator 28a is provided between the outer mold 21 and the upper portion of the inner mold 22, and the intermediate separator 28b is provided between the intermediate portion of the outer mold 21 and the lower portion of the inner mold 22. Separators such as the upper separator 28a and the intermediate separator 28b are appropriately installed at positions between a plurality of supporters 25 provided along the outer form 21.

When the foundation 3 is a cloth foundation, the inner formwork 22 is used so that the position of the lower end portion thereof is the same as the lower end portion of the outer formwork 21, but when the foundation 3 is a solid foundation. The inner formwork 22 is used in which the position of the lower end portion thereof is higher than the lower end portion of the outer formwork 21 and is the same height as the position of the upper surface of the slab portion 11 (FIG. 6).

The single wire shape is a single wire in which the main portion (difference portion) of the ruler body 17 that is a physical difference for defining the position of the anchor bolt 5 is installed along the upper portion 16 (only) of the outer form 21. It is in the shape of (single wire ruler body).

On the other hand, in the double-track shape, as shown in the comparative example of FIG. 17, the ruler main body 102 of the anchor ruler 101 (the difference portion for defining the position of the anchor bolt 5) is the outer form 21 and the inner. It has the shape of a double-track ruler that is installed along the upper portions 16 of both the outer form 21 and the inner form 22 so as to straddle both upper portions 16 of the form 22 (double-track ruler main body). ).

The two line portions 103 and 104 are connected to each other at regular intervals by a connecting portion 105 and integrated. It should be noted that the two line portions 103 and 104 are not directly connected, but are separated into separate members and integrally connected by using a separate connecting member 105 so that the interval is constant at the construction site. It is also possible. In this case, since a separate connecting portion 105 is required in addition to the two separated wire portions 103 and 104, the component configuration becomes complicated as compared with the integrated double-tracked ruler main body 102. , The work man-hours at the construction site will increase due to assembly. Also, it cannot be used in a single wire shape. The double-track anchor ruler 101 such as these is expensive, and only when making one kind of riser 4 having a predetermined width dimension as shown in FIG. 18 (a). Since it cannot be used (for example, it cannot be used when the installation interval between the outer form 21 and the inner form 22 is wider than the specified width dimension as shown in FIGS. 18 (b) and 18 (c)). At present, it is not widely used because it is not versatile and not easy to use.

On the other hand, in the anchor ruler 15 of this embodiment, as shown in FIG. 5, the ruler main body 17 does not have any double-tracked portion installed along the upper portion 16 of the inner form 22 and does not have the outer form. It is a single-line shape having only a single-line portion (difference portion) installed along the upper portion 16 of 21. That is, the ruler main body 17 of this embodiment has a simple structure in which the double-track portion installed along the upper portion 16 of the inner form 22 and the connecting portion between the double-tracks are eliminated.

The single-line-shaped ruler main body 17 includes, for example, a linear ruler (straight-line ruler 29a to 29c) as shown in FIGS. 8A to 8C. The straight rulers 29a to 29c are long members extending along the upper portion 16 of the outer formwork 21 with a substantially constant width dimension w1 as a whole. It is preferable to prepare a plurality of types (at least three types) of the straight line rulers 29a to 29c having the same basic width dimension w1 but different lengths.

In this embodiment, for convenience, the straight line rulers 29a to 29c are used in order from the shortest one. The shortest straight ruler 29a is about half the length of the longest straight ruler 29c. The remaining straight line ruler 29b is slightly longer than the intermediate length between the straight line ruler 29a and the straight line ruler 29c. In the case of a unit building, for example, it is preferable to prepare at least three types of straight line rulers 29a to 29c for each size of the building unit 6. The ruler main body 17 may have sharp corners eliminated by appropriately processing and forming a cornered portion, a rounded portion, or the like on both ends or other portions, if necessary.

(2) The ruler main body 17 having a single wire shape may have an anchor position defining portion 31 that defines a position for installing the anchor bolt 5 on one side edge portion on the inner form 22 side.

Here, the ruler main body 17 is provided with an anchor position defining portion 31 as needed. The anchor position defining portion 31 may be provided in a single number or a plurality with respect to the ruler main body 17. Even if a single or a plurality of anchor position defining portions 31 are provided, the anchor position defining portion 31 may not be used in particular if it is not necessary.

Further, the anchor position defining portion 31 may be provided for all the ruler main bodies 17, but as in this embodiment, the ruler main body 17 having the anchor position defining portion 31 and the anchor position defining portion 31 are provided. A ruler body 17 that does not exist may be provided. Whether or not to provide the anchor position defining portion 31 can be determined according to the installation position of the ruler main body 17 with respect to the outer form 21.

That is, the anchor position defining portion 31 is provided only for the ruler main body 17 installed at the position where the anchor bolt 5 is embedded, and the anchor position is specified for the ruler main body 17 installed at the position where the anchor bolt 5 is not embedded. The section 31 may not be provided in particular.

In this embodiment, a straight line ruler 29b having an intermediate length has an anchor position defining portion 31 and is installed at a position where the anchor bolt 5 is embedded. In the case of a unit building, the straight line ruler 29b provided with the anchor position defining portion 31 is used at a position straddling between the adjacent building units 6 (FIG. 4). In this straight line ruler 29b, there are two places in total, one for each building unit 6, and the anchor position defining portion 31 has a required interval according to the buried position of the anchor bolt 5 for each building unit 6. It is provided.

The other straight line rulers 29a and 29c do not have the anchor position defining portion 31, and are installed at positions where the anchor bolts 5 are not embedded. The straight line rulers 29a and 29c having no anchor position defining portion 31 indirectly define the support position of the anchor bolt 5 by being used together with the straight line ruler 29b having the anchor position defining portion 31.

The anchor position defining portion 31 may be any shape, but in this embodiment, for example, it is partially provided on the edge portion of the ruler main body 17 on the inner form 22 side (protruding toward the inner form 22 side). ) It is designed to have a protrusion 32. The protrusion amount w2 of the protrusion 32 is set to a length that does not reach the buried position of the anchor bolt 5. The edge portion on the inner formwork 22 side extends in the extension direction 33 of the outer formwork 21 and is one of the long sides of the ruler main body 17 located inside the building 1 (one side edge portion). The protrusion 32 is formed, for example, into a substantially rectangular shape in a plan view or a substantially trapezoidal shape in a plan view.

At the position of the protrusion 32, a notch is provided on the edge of the ruler body 17 opposite to the protrusion 32 as a reference (a scale) for the installation position of the anchor bolt 5 with respect to the extension direction 33 of the outer form 21. 34 is formed. The opposite edge extends in the extension direction 33 of the outer form 21 and is located outside the building 1 and has another length of the ruler body 17 (parallel to the edge on the inner form 22 side). It is a side (other side edge). A similar notch 34 (scale) is an anchor at the edge of the ruler body 17 on the outer form 21 side, if necessary, so that various positions other than the installation position of the anchor bolt 5 can be defined. A single or a plurality of portions may be provided in a portion (general portion) other than the position defining portion 31. In this embodiment, the notch portion 34 of the portion other than the anchor position defining portion 31 is not particularly provided, but for example, the installation position of the straight line rulers 29a and 29c is accurately defined with respect to the straight line rulers 29a and 29c. It can be provided for such purposes. The cutout portion 34 is, for example, a V-cut portion or the like.

The protruding portion 32 has a positioning portion 36 (which functions as a scale or a mark for accurately defining the position of the anchor bolt 5 with respect to the extension direction 33 of the outer form 21 and the width direction 35 of the outer form 21. Positioning holes or notches) are provided. In the following description, the extension direction 33 of the outer form 21 and the width direction 35 of the outer form 21 will be used as a reference. The extension direction 33 of the outer form 21 and the width direction 35 of the outer form 21 are the extension directions 33 and the extension directions 33 of the straight rulers 29a to 29c with the straight rulers 29a to 29c installed on the upper portion 16 of the outer form 21. It coincides with the width direction 35, respectively.

The positioning portion 36 may be of any shape, but in this embodiment, the positioning portion 36 has a hole shape formed inside the protruding portion 32, which is a combination of a round hole and a slit. ing. The slit of the positioning portion 36 is supposed to extend in the width direction 35. The slit of the positioning portion 36 has an edge portion (one side) on the inner form 22 side of the ruler main body 17 (general portion = portion without the protruding portion 32) with respect to the protruding portion 32 at the outer end portion of the building 1. It is formed so that it is in the same position as the edge). This makes it possible to use one side edge of the ruler body 17 as a reference for the position. The inner end of the building 1 in the slit of the positioning portion 36 is formed at a position not reaching the tip of the protruding portion 32 (however, the slit is opened to the tip side so as to reach the tip of the protruding portion 32). May be). The positioning portion 36 may be only a slit extending in the width direction 35. In this embodiment, the positioning portion 36 and the notch portion 34 are located at substantially the same position in the extending direction 33, which is approximately the middle portion of the extending direction 33 of the projecting portion 32 having a substantially rectangular or trapezoidal shape in a plan view. The ruler body 17 is formed so as to penetrate vertically in a state of substantially facing the width direction 35.

Then, as shown in FIG. 9, the anchor bolt 5 is held and arranged inside the formwork 13 on the protruding portion 32 constituting the anchor position defining portion 31 in the ruler main body 17, as shown in FIG. A metal anchor plate 37 for abutment is arranged. The anchor plate 37 constitutes a part of the set of the anchor ruler 15 as the auxiliary member described above. By configuring the anchor plate 37 separately from the ruler body 17, the ruler body 17 indirectly defines the embedding position of the anchor bolt 5, and the anchor plate 37 can be replaced with an appropriate one. For example, the burial position of the anchor bolt 5 with respect to the width direction 35 or the extension direction 33 of the rising portion 4 can be changed or adjusted, for example, the number of anchor bolts 5 to be buried in one place can be changed, for example, the diameter dimension. It becomes possible to freely use different anchor bolts 5. That is, the versatility of the ruler body 17 can be expanded. Although the anchor plate 37 is very effective for installing the anchor bolt 5, it is not always necessary to use the anchor plate 37. For example, the anchor plate 37 is based on the position of the position determination portion 36 of the anchor position defining portion 31. It is also possible to install the anchor bolt 5 by another means or jig.

As shown in FIG. 10, the anchor plate 37 is a relatively narrow member whose width direction is the extension direction 33, and is from the plate body 37a installed on the upper portion 16 of the outer form 21 and the plate body 37a. A first lateral extension 37b extending to the side of the inner form 22, a vertical extension 37c extending downward from the tip of the first horizontal extension 37b, and an inner portion from the lower end of the vertical extension 37c. It has a second laterally extended portion 37d extending to the side of the form 22. It is preferable that the anchor plate 37 is formed by processing a rounded portion in each portion to eliminate sharp corners.

The plate body 37a abuts on the upper portion 16 of the outer form 21 with a width dimension substantially the same as or narrower than the width dimension w1 of the ruler body 17 in the width direction 35.

The first lateral extension portion 37b, the vertical extension portion 37c, and the second lateral extension portion 37d are portions that project from the upper portion 16 of the outer formwork 21 to the inside of the building 1 and are anchors. A bolt holding portion for holding the bolt 5 is formed. The bolt holding portion (first lateral extension portion 37b, vertical extension portion 37c, second horizontal extension portion 37d) is wider than the length of the plate body 37a with respect to the extension direction 33 (dimensions in the extension direction 33). ) May be narrowly formed, but in this embodiment, the width of the bolt holding portion is formed to be the same as the length of the plate body 37a in the extending direction 33. As a result, the anchor plate 37 can be made into a simple shape, facilitate mass production, and increase the strength of the bolt holding portion.

A notch 37e that matches the notch 34 of the protrusion 32 is provided on the edge of the plate body 37a opposite to the bolt holding portion. The cutout portion 37e is, for example, a V-cut portion having substantially the same shape and size as the cutout portion 34. The notch 37e is provided, for example, at the center of the plate body 37a in the extending direction 33 so as to penetrate the plate body 37a up and down.

Then, with the notch 34 at the position of the protrusion 32 and the notch 37e of the plate body 37a aligned, the plate body 37a is attached to the ruler body 17 and the upper portion 16 of the outer form 21 with a fixing tool such as a vise. By fixing the outer formwork 21 so as not to rise using 38 (FIG. 9 (c)), the positions of the anchor plate 37 and the anchor bolt 5 with respect to the extension direction 33 and the width direction 35 of the outer form 21 are (finally). It is defined accurately. The fixing tool 38 such as a vise may be a general one, or may be provided as an auxiliary member described above as a part of a set of the anchor ruler 15.

The first laterally extended portion 37b and the second laterally extended portion 37d forming the bolt holding portion are formed by the vertically extended portion 37c with an upper and lower step. That is, the bolt holding portion has a stepped shape when viewed from the side. At this time, the first laterally extended portion 37b is provided substantially flush with the plate main body 37a, and is substantially the same as or longer than the protrusion amount w2 of the protrusion 32 in the width direction 35, and moreover. It is formed to a length that does not reach the buried position of the anchor bolt 5. Since the plate body 37a and the first lateral extension portion 37b are flush with each other, if the lengths of the extension directions 33 are the same, they are identified and cannot be distinguished, but the length of the extension direction 33 is the same. By making them different, they can be clearly distinguished.

The second lateral extension 37d is installed at a position lower than the plate main body 37a and the first lateral extension 37b and higher than the upper end surface of the rising portion 4. The second lateral extension portion 37d is formed to have a length exceeding the embedded position of the anchor bolt 5, and a bolt holding hole 37f for passing the anchor bolt 5 in the vertical direction is formed through. The bolt holding hole 37f is formed in a size that allows the anchor bolt 5 to be inserted (a diameter substantially the same as the outer diameter of the anchor bolt 5). It is preferable that the center of the bolt holding hole 37f is formed at the same position in the notch 37e and the extending direction 33.

Then, the anchor bolt 5 is passed through the bolt holding hole 37f formed in the second lateral extension portion 37d, and is screwed to the anchor bolt 5 with the upper and lower nuts 39 (FIG. 9A). By sandwiching the upper and lower surfaces of the second laterally extended portion 37d up and down, it is held by the second laterally extended portion 37d.

Further, a wedge mounting hole 37g for mounting the fixing wedge 41 (FIG. 11) is formed through the first laterally extending portion 37b of the anchor plate 37. Then, as shown in FIG. 9B, a ruler is inserted by inserting the fixing wedge 41 from above between the wedge mounting hole 37g provided in the anchor plate 37 and the positioning portion 36 of the protruding portion 32. The positions of the anchor plate 37 in the width direction 35 and the extension direction 33 with respect to the anchor position defining portion 31 (or the outer form 21) of the main body 17 are accurately and surely defined. The fixing wedge 41 constitutes a part of the set of the anchor ruler 15 as the auxiliary member described above.

In this embodiment, the wedge mounting hole 37g has a shape in which a round hole and a slit are combined as in the positioning portion 36. At this time, the wedge mounting hole 37g is preferably the same size and shape as the positioning portion 36, but the wedge mounting hole 37g can be slightly larger than the positioning portion 36. The slit of the wedge mounting hole 37 g extends in the width direction 35 like the positioning portion 36. In this embodiment, the wedge mounting hole 37 g is formed to have a size (the same size as the positioning portion 36) into which the fixing wedge 41 can be inserted.

The wedge mounting hole 37g and the notch 37e (and the bolt holding hole 37f) are arranged in a line in the width direction 35 at substantially the same position in the extension direction 33 of the anchor plate 37. It is formed so as to penetrate up and down.

As shown in FIG. 11, the fixing wedge 41 is composed of vertically short strip-shaped metal plates having a surface extending in the width direction 35 and a surface extending in the vertical direction (or a surface perpendicular to the extending direction 33). The middle portion in the vertical direction is a parallel portion 41a, the head portion 41b extending in the width direction 35 is provided at the upper portion, and the edge portion on the outer mold 21 side is cut diagonally so as to be narrowed at the lower portion. It has a portion 41c. The parallel portion 41a has a width substantially the same as the length of the slit of the wedge mounting hole 37g and extends vertically, and the lower inclined portion 41c is on the back side of the positioning portion 36 of the protrusion 32 (outside of the building 1). By being guided to the end portion of, the anchor plate 37 functions as a wedge and the position of the anchor plate 37 is adjusted in the width direction 35, and the parallel portion 41a of the intermediate portion is guided to the inner portion of the positioning portion 36 of the protruding portion 32. As a result, the anchor plate 37 is stably held in the correct position. In the fixing wedge 41, it is preferable to process and form a rounded shape portion 41d in each portion to eliminate sharp corners, and in particular, a rounded shape portion 41d is formed in a portion (particularly the tip portion) around the inclined portion 41c. By providing it, the effect of making it easier to enter the wedge mounting hole 37 g can be obtained.

Further, as shown in FIG. 9, when the heat insulating material 42 is integrally installed on the inner surface side (inside of the building 1) of the rising portion 4, the heat insulating material 42 is arranged in contact with the inner surface of the inner form 22. A pressing holding metal fitting 43 may be provided to hold the side surface 42a (inner side surface) of the outer mold 21 from the side of the outer mold 21 toward the side of the inner mold 22 in the width direction 35.

The pressing holding metal fitting 43 integrally integrates at least a horizontal and flat holding surface 43a and a surface 43b that extends downward from the edge of the holding surface 43a on the heat insulating material 42 side and abuts and holds the side surface 42a of the heat insulating material 42. Have in.

It is preferable that the holding surface 43a has a length of 35 in the width direction, which is substantially the same as the width dimension 27 of the rising portion 4, and is interposed between the outer form 21 and the heat insulating material 42. A bolt hole 43c through which the anchor bolt 5 is passed is formed through the holding surface 43a, and by passing the anchor bolt 5 through the bolt hole 43c, the pressing holding metal fitting 43 holds the anchor bolt 5 and is formed by the anchor bolt 5. Be retained. The pressing holding metal fitting 43 may be fixed to the anchor bolt 5 by sandwiching the upper and lower surfaces of the holding surface 43a up and down using, for example, the same upper and lower nuts 39 screwed to the anchor plate 37. good.

Further, the pressing holding metal fitting 43 integrally has another facing portion that extends downward and is abutted and held on the inner surface of the outer form 21 at the edge portion of the holding surface 43a on the side opposite to the contact surface 43b.

(3) As shown in FIG. 12, the single-line ruler main body 17 installed along the upper portion 16 of the outer form 21 forming the corner portion 51 of the rising portion 4 has a first straight line as shown in FIG. An L-shaped plan view having a portion 53 and a second straight line portion 54 orthogonal to the first straight line portion 53 may be formed.
Then, an oblique member 55 connecting the first straight line portion 53 and the second straight line portion 54 may be provided between the first straight line portion 53 and the second straight line portion 54.

Here, the corner portion 51 of the rising portion 4 is formed in a corner portion of the building 1 or the like. The corner portion 51 is normally formed at a right angle. The corner portion 51 has an outside corner, an inside corner, and the like. The outside corner is a general corner portion 51 protruding outside the building 1, and the inside corner is a corner portion 51 recessed inside the building 1. The inside corner is formed, for example, in a portion where building units 6 having different sizes are combined, or in a portion where the building units 6 are installed in a staggered manner.

The first straight portion 53 has a substantially constant width dimension w1 along the upper portion 16 of one of the outer formwork 21 of the outer formwork 21 assembled at a right angle to form the corner portion 51 of the rising portion 4. It is provided so as to extend.

The second straight line portion 54 is provided along the upper portion 16 of the other outer form 21 forming the corner portion 51 of the rising portion 4 so as to extend with a substantially constant width dimension w1. The second straight line portion 54 is integrally formed with the first straight line portion 53. The width dimension w1 of the first straight line portion 53 and the second straight line portion 54 is the same as the width dimension w1 of the straight line rulers 29a to 29c.

The corner portion (or bent portion) connecting the first straight line portion 53 and the second straight line portion 54 may be provided with, for example, a hole portion indicating the width center position of both the first straight line portion 53 and the second straight line portion 54. good.

The first straight line portion 53 and the second straight line portion 54 may have the same length, but in this embodiment, the first straight line portion 53 and the second straight line portion 54 have different lengths. Since the ruler main body 17 installed on the upper portion 16 of the outer mold 21 forming the corner portion 51 can be used by being inverted (front and back inversion, upside down, left and right inversion), the first straight line portion 53 and the second straight line portion are used. The 54 is relative, but for convenience, the long side is the first straight line portion 53 and the short side is the second straight line portion 54.

The diagonal member 55 is a reinforcing portion that is diagonally erected and connected between the intermediate portion of the first straight line portion 53 and the intermediate portion of the second straight line portion 54. The diagonal member 55 is integrally formed with the first straight line portion 53 and the second straight line portion 54. Although the diagonal member 55 is not used for directly defining the position of the anchor bolt 5, it is preferable to provide the diagonal member 55 as a reinforcing portion for maintaining the shape of the first straight line portion 53 and the second straight line portion 54. .. By providing the diagonal member 55, the ruler main body 17 installed on the upper portion 16 of the outer form 21 forming the corner portion 51 does not have a pure single wire shape, but the position of the anchor bolt 5 is defined. If the first straight line portion 53 and the second straight line portion 54, which are the physical difference portions of the above, have a single wire shape, it can be said that the diagonal member 55 has a substantially single wire shape. The width dimension of the diagonal member 55 may be the same as or different from the width dimension w1 of the first straight line portion 53 and the second straight line portion 54.

The ruler main body 17 including the first straight line portion 53 and the second straight line portion 54 is a metal corner ruler 52a, 52b having a right-angled corner portion. The corner rulers 52a and 52b include at least one for the outside corner (corner ruler 52a) as shown in FIG. 13 (a) and one for the inside corner (corner ruler 52b) as shown in FIG. 13 (b). Two types are prepared.

The corner ruler 52a for the outside corner and the corner ruler 52b for the inside corner may have the same shape, but in this embodiment, the corner ruler 52a for the outside corner and the corner ruler 52b for the inside corner are different. It has a different shape. The corner ruler 52a for the protruding corner has a shape in which the short side (second straight line portion 54) is relatively long with respect to the long side (first straight line portion 53). The corner ruler 52b for entering a corner has a shape in which the short side (second straight line portion 54) is relatively short with respect to the long side (first straight line portion 53).

Further, the corner rulers 52a and 52b may be provided with one or a plurality of the same anchor position defining portions 31 as described above, if necessary. The anchor position defining portion 31 is provided on one or both of the first straight line portion 53 and the second straight line portion 54 at the edge portion (one side edge portion) on the inner form 22 side. In general, the anchor bolt 5 is often provided at the corner portion 51 of the rising portion 4 or the peripheral portion thereof. Therefore, the corner rulers 52a and 52b are provided with the anchor position defining portion 31 at the right-angled corner portion and the periphery thereof. There is a high possibility that it will be. The anchor position defining portion 31 may not be used if it is not necessary even if it is provided.

In terms of strength, the anchor position defining portion 31 is preferably provided within the range of the triangular portion surrounded by the first straight line portion 53, the second straight line portion 54, and the diagonal member 55. Therefore, the diagonal member 55 is installed at a position (a position closer to the end than the anchor position defining portion 31) so that the anchor position defining portion 31 is included in the range of the above-mentioned triangular portion. As a result, when the corner rulers 52a and 52b are installed on the upper portion 16 of the outer formwork 21, the diagonal member 55 may partially intersect with the inner formwork 22, but the diagonal member 55 is a reinforcing portion. Since it does not follow the inner formwork 22, even if it intersects with the inner formwork 22, it does not affect the arrangement of the inner formwork 22 with respect to the outer formwork 21.

Specifically, in the corner ruler 52a for the protruding corner, the anchor position defining portion 31 is such that the protruding portion 32 projects to the inside of the triangle at a position inside the triangle within the range of the triangular portion. It is formed. In this embodiment, with respect to the corner ruler 52a for the protruding corner, the anchor position defining portion 31 is provided at one position in the first straight line portion 53, and is not particularly provided in the second straight line portion 54. However, the installation location and the number of anchor position defining portions 31 with respect to the corner ruler 52a for protruding corners are not limited to this.

Further, in the corner ruler 52b for entering a corner, the anchor position defining portion 31 is formed so that the protruding portion 32 projects to the outside of the triangle at a position outside the triangle within the range of the triangular portion. It will be. In this embodiment, the anchor position defining portion 31 is not particularly provided for the corner ruler 52b for entering a corner, but when the anchor position defining portion 31 is provided, for example, one place is provided in the first straight portion 53. It may be provided. However, the installation location and the number of anchor position defining portions 31 with respect to the corner ruler 52b for entering corners are not limited to this.

(4) As shown in FIG. 14, connection fittings 61A and 61B for connecting between a plurality of ruler main bodies 17 are provided.
As shown in the embodiments of FIGS. 15A and 15B, the connection fittings 61A and 61B have width dimensions 63a and 63b that match the width dimension 62 (FIG. 14A) of the upper portion 16 of the outer form 21. Is also good.

Here, the connection fittings 61A and 61B form a part of the set of the anchor ruler 15 as the auxiliary member described above.

The width dimensions 63a and 63b matched to the width dimension 62 (FIG. 14A) of the upper portion 16 of the outer form 21 are substantially the same as the width dimension 62 of the upper portion 16 of the outer form 21 with the connection fittings 61A and 61B. To have a width dimension. As a result, the connection fittings 61A and 61B function as locking fittings in the width direction 35 with respect to the upper portion 16 of the outer form 21.

Although not shown in particular, there are already several types of outer form 21 having different width dimensions 62 of the upper portion 16. The width dimension 62 of the upper portion 16 of the outer form 21 has at least two types, one having a relatively narrow width (for example, 45 mm) and the other having a wide width (for example, 50 mm).

Therefore, the connection fittings 61A and 61B have substantially the same width dimensions 63a and 63b (or have different width dimensions 63a and 63b) according to various width dimensions 62 of the upper portion 16 of the outer form 21. ) Are prepared in multiple types.

For example, the connection fittings 61A and 61B have a width dimension of 63a for narrow width (for example, for 45 mm) (connection fitting 61A, FIG. 15A) and a width dimension 63b for wide width (for example, for 50 mm) (for example, for 50 mm). At least two types of width dimensions 63a and 63b, such as connection fittings 61B and FIG. 15B), are provided (width dimension 63a <width dimension 63b). However, the types and width dimensions 62 of the upper portion 16 of the outer form 21 and the types and width dimensions 63a and 63b of the connection fittings 61A and 61B are not limited to the above.

In this case, for the ruler main body 17, the width dimension w1 is the same as the one having the smallest width dimension 62 among the upper portions 16 of the plurality of types of outer form 21, or the width dimension w1 is made smaller than that. Is preferable. Then, the ruler body 17 is installed in a state where the edge of the upper portion 16 of the outer form 21 on the inner form 22 side is aligned with the edge of the ruler body 17 on the inner form 22 side, and the width dimension of the upper 16 of the outer form 21 is set. The connection fittings 61A and 61B having substantially the same width dimension 63a and 63b as 62 are attached. As a result, the ruler body 17 can be installed and used without any trouble even on the outer form 21 in which the width dimension 62 of the upper portion 16 of the outer form 21 is wider than the width dimension w1 of the ruler body 17. ..

That is, when the ruler main body 17 having the same width dimension w1 as the width dimension 62 of the upper portion 16 of the outer form 21 is installed (contact arrangement from the upper side) with respect to the upper portion 16 of the outer form 21, the ruler main body 17 Both side edges of the outer mold 21 are aligned with the side edges of the upper portion 16 of the outer mold 21. Then, by attaching the connection fittings 61A and 61B having the same width dimensions 63a and 63b as the width dimension 62 of the upper portion 16 of the outer form 21, the upper portion 16 of the outer form 21 and the ruler body 17 are connected to the connection fittings 61A and 61B. The edges on both sides are partially locked and held in the width direction 35.

Further, when the ruler main body 17 having a width dimension w1 narrower than the width dimension 62 of the upper portion 16 of the outer form 21 is installed (contact arrangement from the upper side) with respect to the upper portion 16 of the outer form 21, the ruler main body Only the edge of 17 on the inner form 22 side is aligned with the edge of the upper 16 of the outer form 21 on the inner form 22 side, and the opposite edges do not match each other (on the upper 16 of the outer form 21). On the other hand, the ruler body 17 is retracted inside the building 1). Then, by attaching the connection fittings 61A and 61B having the same width dimensions as the upper portion 16 of the outer formwork 21, the upper portion 16 of the outer formwork 21 has both side edges 35 in the width direction by the connection fittings 61A and 61B. The ruler body 17 is partially locked and held by the connecting metal fittings 61A and 61B in a state where the upper portion 16 of the outer form 21 and the edges on the inner form 22 side are aligned with each other. Become.

Therefore, in either case, the ruler body 17 is correctly set with respect to the upper portion 16 of the outer form 21, so that the anchor bolt 5 can be accurately installed at the embedded position.

(5) Specifically, the connection fittings 61A and 61B are
The connection fitting main body 61a, which is abutted and arranged on the upper portion 16 of the outer form 21 and the ruler main body 17, and
It has a locking portion 61b that extends downward from both side edges of the connecting metal fitting body 61a (mounted on the ruler body 17) and locks the upper portion 16 of the outer form 21 in the width direction 35. You may.
Then, as shown in FIG. 14, the ruler main body 17 having a single wire shape has a width expansion portion having a connecting hole 65 into which the locking portion 61b is inserted, at or near both ends of one side edge portion on the inner form 22 side. 64 may be provided.

Here, the connection fitting main body 61a is a short material having a horizontal and flat surface that is abutted and arranged on the general portion of the ruler main body 17 and the width expansion portion 64. The connection fitting main body 61a has substantially the same width dimensions 63a and 63b as the width dimension 62 of the upper portion 16 of the outer form 21. The length of the connecting metal fitting body 61a in the extending direction 33 is substantially the same as or larger than the distance between the connecting holes 65.

The locking portion 61b may be integrally formed with the connection fitting main body 61a by bending or the like. As a result, the locking portion 61b becomes a planar shape that enters the connecting hole 65 (slit described later). In this case, the locking portion 61b is preferably formed to have a width substantially the same as the length of the connecting hole 65 (slit). The locking portion 61b may be such that a pin separate from the connection fitting main body 61a is attached to the connection fitting main body 61a. It is preferable that the locking portion 61b is formed with a tapered introduction tapered portion 61c or the like at the tip end portion (lower end portion) so that the locking portion 61b can easily enter the connecting hole 65. Further, it is preferable that the connection fittings 61A and 61B are formed by processing a rounded shape portion in each portion to eliminate sharp corners, but in particular, the rounded shape is formed in the peripheral portion (particularly the tip portion) of the introduction taper portion 61c. By processing and forming the portion 61d to eliminate the corners, the effect of making it easier to enter the connecting hole 65 can be obtained.

The locking portion 61b sandwiches the upper portion 16 of the outer form 21 from both sides in the width direction 35 when the connection fitting main body 61a is abutted on the ruler main body 17 or the width expanding portion 64. The upper portion 16 of the frame 21 is provided as a pair in the width direction 35 so as to be locked in the width direction 35. As a result, the connection fittings 61A and 61B function as locking fittings as described above. The paired locking portions 61b are set to be substantially the same as the width dimension 62 of the upper portion 16 of the outer mold 21 (the width dimensions 63a and 63b between the inner surfaces). The number of locking portions 61b is the same as that of the connecting holes 65 at the same position as the connecting holes 65 (two pairs or four in this embodiment) according to the number and arrangement of the connecting holes 65 (or the interval of the extension direction 33). ) Provided.

Further, the pair of locking portions 61b may have the same length as each other, but for example, as shown in other embodiments of the connection fittings 61A and 61B of FIGS. 16A and 16B, they can be easily inserted into the connecting hole 65. As you can see, the lengths may be different. That is, the locking portion 61b'on the opposite side may be shorter or longer than the locking portion 61b on one side having the specified length. As a result, for example, by inserting the relatively long locking portion (for example, the locking portion 61b) into the connecting hole 65 first, the adjacent connection fittings 61A and 61B are connected and integrated. (Stable connection is achieved), so that the relatively shorter locking portion (for example, the locking portion 61b') can be easily hooked to the opposite edge portion, and the connection fittings 61A and 61B can be more easily hooked. Can be attached to the upper portion 16 of the outer form 21 and locked in the width direction 35, and workability can be improved.

On the other hand, the ruler main body 17 is installed in a state of being abutted against the upper portion 16 of the outer form 21 and being superposed on the adjacent ruler main body 17 by a required amount. The width expanding portion 64 described above is provided in the overlapping portion between the ruler bodies 17, and the connecting hole 65 is formed through the width expanding portion 64. A connection portion between the ruler bodies 17 is formed by the width expansion portion 64 and the connecting hole 65. This connection portion is connected to each other by using connection fittings 61A and 61B.

The width expansion portion 64 is partially projected from the edge of the ruler main body 17 on the side of the inner formwork 22 so as to project inward of the building 1. The width expanding portion 64 is formed, for example, in a substantially trapezoidal shape in a plan view. Even if the protrusion amount w3 (FIG. 8 or 13) of the width expanding portion 64 with respect to the ruler body 17 (general portion) in the width direction 35 is substantially the same as the protrusion amount w2 of the protrusion 32 in the width direction 35. It is good, but it is sufficient if the connecting hole 65 can be formed, so it is preferable that the protrusion amount is smaller than w2.

The width expanding portion 64 is mainly provided at both ends of the ruler main body 17. A single or a plurality of width expanding portions 64 are provided at each end of the ruler main body 17. When a plurality of width expanding portions 64 are provided at the ends of the ruler main body 17, it is preferable that the width expanding portions 64 are provided apart by a required distance. As a result, the connecting length between the adjacent ruler main bodies 17 can be adjusted and changed by selecting and using any one of the plurality of width expanding portions 64 provided. In this embodiment, the plurality of width expanding portions 64 are provided with respect to the first straight portion 53 which is the long side of the corner rulers 52a and 52b (FIG. 13). Further, each end of the straight line rulers 29a to 29c (FIG. 8) may be provided with a plurality of width expanding portions 64, but in this embodiment, they are not particularly provided and are singular.

Then, a single or a large number of connecting holes 65 of the width expanding portion 64 that are vertically overlapped on the upper and lower sides of the adjacent ruler main body 17 are provided at positions that coincide with each other on the upper and lower sides. In this embodiment, two connecting holes 65 are provided in each width expanding portion 64 along the extending direction 33. In this embodiment, the two connecting holes 65 are the basic of the ruler main body 17. It is formed at an interval approximately equal to or wider than the width dimension w1. Further, the connecting hole 65 has a shape in which a round hole and a slit are combined. The slit is extended toward the extension direction 33 of the outer form 21. The slit is formed so as to fit the locking portion 61b.

The connecting hole 65 is substantially located at the root portion of the width expanding portion 64 expanded to the side of the inner formwork 22, that is, the edge portion of the ruler body 17 (general portion) on the inner formwork 22 side (inside). It is provided (side by side) at a position on the line along the line. As a result, when the connection fittings 61A and 61B are installed at the position of the width expansion portion 64, the locking portion 61b on the inner formwork 22 side of the connection fittings 61A and 61B is inserted into the connection hole 65, and the adjacent ruler main body is inserted. The ends of the 17 are connected and fixed to each other, and the ruler body 17 is in a state where the edge on the inner form 22 side matches the edge on the inner form 22 side of the upper portion 16 of the outer form 21. ..

Finally, to summarize the ruler main body 17, the ruler main body 17 is a member made of a flat metal plate having a required wall thickness. , It is arranged in contact with the upper portion 16 of the outer mold 21 from above. The ruler main body 17 is mainly composed of a difference portion extending along the upper portion 16 of the outer form 21 with a substantially uniform width dimension w1. The ruler main body 17 has an edge portion (one side edge portion) on the inner form 22 side and an edge portion (other side edge portion) on the opposite side thereof, and the edge portion on the inner form 22 side is an outer mold. It is installed so as to be aligned with the upper portion 16 of the frame 21. On the edge portion on the inner form 22 side, a single or a plurality of partially widened portions 64 having connecting holes 65 as connecting portions are formed at or near both ends thereof. The widening portion 64 and the connecting hole 65 are not provided on the opposite edge. Further, on the edge portion on the inner form 22 side, a single or a plurality of partial protrusions 32 having the positioning portion 36 as the anchor position defining portion 31 can be formed. The anchor position defining portion 31 does not interfere with the connection function by the width expanding portion 64 or the connecting hole 65 at the position between both ends of the ruler body 17 or between the width expanding portions 64 near the ends (where the anchor bolt 5 is embedded). It is provided as follows. Then, on the edge of the ruler main body 17 on the opposite side to the above, notches 34, which serve as reference for various positions, are formed as a single or a plurality of notches, if necessary. The notch 34 includes one for accurately defining the buried position of the anchor bolt 5. The notch 34 for accurately defining the buried position of the anchor bolt 5 is, for example, the position of the anchor plate 37 (for holding the anchor bolt 5) installed with respect to the ruler body 17 in the extending direction 33. Can be used to specify.

The ruler body 17 includes straight rulers 29a to 29c (FIG. 8) installed in the straight portion of the outer form 21 and corner rulers 52a and 52b (FIG. 8) installed in the right-angled portion of the outer form 21. There is 13).

The straight rulers 29a to 29c are long strip-shaped members having a difference portion extending almost straight. The straight rulers 29a to 29c have no portion installed along the upper portion 16 of the inner formwork 22, but have only a portion installed along the upper portion 16 of the outer formwork 21. ..

The corner rulers 52a and 52b are L-shaped members in a plan view having a difference portion in which the middle portion is bent at a right angle (or the middle portion is a bent portion at a right angle). An oblique member 55 may be integrally provided between the first straight line portion 53 forming the L-shape of the corner rulers 52a and 52b and the second straight line portion 54 (in the middle portion) so as to be diagonally connected. .. The diagonal member 55 is provided at a position that does not interfere with the functions of the connecting portion (width expanding portion 64 and the connecting hole 65) and the anchor positioning portion 31. The diagonal member 55 is preferably provided at a position closer to the end than the anchor position defining portion 31. The diagonal member 55 has the possibility of partially intersecting the upper portion 16 of the inner formwork 22, but does not extend along the upper portion 16 of the inner formwork 22. Therefore, the corner rulers 52a and 52b have no portion installed along the upper portion 16 of the inner formwork 22, but have only a portion installed along the upper portion 16 of the outer formwork 21. ing.

<Action> The action of this example will be described below.

When the foundation 3 is placed on the ground 2 with concrete 14, the outer formwork 21 and the inner formwork 22 are formed on the ground 2 so that at least the rising portion 4 (outer peripheral rising portion) matching the outer shape of the building 1 is formed. And are erected in parallel with the required spacing. At this time, the distance between the outer form 21 and the inner form 22 is generally set to be the same as the width dimension 27 of the rising portion 4, but for example, the heat insulating material 42 is integrally provided on the rising portion 4. In this case, they are installed at intervals wider than the width dimension 27 of the rising portion 4 by the thickness of the heat insulating material 42.

After installing the outer formwork 21 and the inner formwork 22 on the ground 2, next, the upper part 16 (only) of the outer formwork 21 has a single line shape so as to be continuous along the upper part 16 of the outer formwork 21. A plurality of ruler bodies 17 are installed (FIG. 5). It should be noted that at least the difference portion of the ruler main body 17 is not installed on the upper portion 16 of the inner form 22.

Then, the adjacent ruler bodies 17 are connected and fixed to each other by the connecting fittings 61A and 61B having the width dimensions 63a and 63b matching the width dimension 62 of the upper portion 16 of the outer form 21, and the rulers are connected and fixed by the connecting fittings 61A and 61B. The main body 17 is partially held or locked by the upper portion 16 of the outer form 21 in the width direction 35 (FIG. 14).

At this time, straight rulers 29a to 29c are installed on the outer form 21 forming the straight portion of the rising portion 4, and corner rulers 52a and 52b are installed on the outer form 21 forming the corner portion 51 (. FIG. 12 (a)). In order to accurately attach the ruler body 17 to the upper portion 16 of the outer form 21, the corner rulers 52a and 52b are installed first, and the straight rulers 29a to 29c are connected to the corner rulers 52a and 52b. Is preferable. The corner rulers 52a and 52b are accurately installed on the upper portion 16 of the outer formwork 21 with reference to the water thread or the like attached to the ground 2. At this time, the ruler main body 17 is aligned inside with respect to the outer form 21. That is, the positions of the edges of the ruler body 17 and the outer formwork 21 on the inner formwork 22 side are aligned with each other in the width direction 35.

The connection between the corner rulers 52a and 52b and the straight line rulers 29a to 29c and between the straight line rulers 29a to 29c is located inside the connection fittings 61A and 61B with the width expansion portions 64 overlapped vertically. This is done by simultaneously inserting the locking portions 61b to be inserted into the connecting holes 65 of the width expanding portions 64 that are vertically overlapped with each other. As a result, as described above, the locking portion 61b located on the outside of the connection fittings 61A and 61B is locked to the outer edge portion of the upper portion 16 of the outer form 21 and is located inside the connection fittings 61A and 61B. Since the stop portion 61b is locked to the inner edge portion of the upper portion 16 of the outer form 21, the ruler main body 17 is locked and held in the width direction 35 with respect to the upper portion 16 of the outer form 21 in an inwardly aligned state. .. At this time, among the plurality of types of connection fittings 61A and 61B, those having width dimensions 63a and 63b that match the width dimension 62 of the upper portion 16 of the outer form 21 are used.

The connection fittings 61A and 61B can be installed even in a position where the width expansion portion 64 and the anchor position defining portion 31 are not provided, whereby each part of the ruler body 17 is widened with respect to the upper portion 16 of the outer form 21. It can be used to partially hold or lock hold in direction 35. For example, as shown in FIG. 12 (b), with respect to the outer form 21 installed in the corner portion 51, both side portions in the vicinity of the corner portion of the corner rulers 52a and 52b (in this case, the corner ruler 52a) are provided. By attaching the connection fittings 61A and 61B so as to straddle the width direction 35, the corner rulers 52a and 52b are accurately held or locked in two orthogonal directions.

Then, the corner rulers 52a and 52b and the straight rulers 29a to 29c are appropriately widened by a fixing tool 38 (FIG. 9 (c)) such as a vise before and after locking and holding in the width direction 35. A portion other than the portion 64 and the anchor position defining portion 31 may be temporarily fixed or finally fixed to the upper portion 16 of the outer form 21.

Then, as shown in FIG. 9, the anchor plate 37 to which the anchor bolt 5 is attached is attached to the anchor position defining portion 31 of the ruler main body 17.

At this time, first, the anchor bolt 5 is inserted into the bolt holding hole 37f of the anchor plate 37, and the upper and lower surfaces of the second lateral extension portion 37d are vertically sandwiched between the upper and lower nuts 39 screwed to the anchor plate 37. Then, the anchor bolt 5 is attached to the anchor plate 37. The anchor bolt 5 adjusts the screwing amount of the nut 39 so that the protrusion amount of the upper end portion from the nut 39 on the upper side of the anchor plate 37 becomes a predetermined value.

Next, as shown in FIG. 9A, the anchor plate 37 is installed on the anchor position defining portion 31 of the ruler main body 17, and the notch portion 34 provided at the position opposite to the protruding portion 32 and the anchor. By aligning with the notch 37e provided in the plate body 37a of the plate 37, the anchor plate 37 and the anchor bolt 5 are roughly positioned in the extending direction 33 with respect to the ruler body 17.

Then, as shown in FIG. 9B, the upper part is between the wedge mounting hole 37g provided in the anchor plate 37 and the positioning portion 36 provided in the protruding portion 32 of the anchor position defining portion 31 of the ruler main body 17. By inserting the fixing wedge 41 from the anchor plate 37, the positions of the anchor plate 37 and the anchor bolt 5 with respect to the width direction 35 and the extension direction 33 are more accurately defined (positioning and temporary fixing).

Finally, as shown in FIG. 9 (c), the anchor plate 37 and the ruler main body 17 are firmly and surely booked so as not to move with respect to the outer formwork 21 by using a fixture 38 such as a vise. Fix it.

When the heat insulating material 42 is integrally installed on the rising portion 4, a pressing holding metal fitting 43 is attached to the anchor bolt 5 to press the side surface 42a of the heat insulating material 42 installed on the inner surface of the inner form 22. It is pressed in the width direction 35 by the foreground 43b of the holding metal fitting 43.

Then, in this state, the concrete 14 is placed between the outer formwork 21 and the inner formwork 22 to form the rising portion 4. As a result, the anchor bolt 5 is installed at an accurate position while being embedded in the rising portion 4. Further, when the heat insulating material 42 is installed on the inner surface of the inner form 22, the heat insulating material 42 is installed integrally with the rising portion 4 inside the rising portion 4. The concrete 14 is filled up to a position approximately at the height of the upper surface of the heat insulating material 42.

<Effect> According to this embodiment, the following effects can be obtained.

(Action effect 1) In the anchor ruler 15, the ruler body 17 (the difference portion for defining the position of the anchor bolt 5) is installed along the upper portion 16 (only) of the outer form 21 in a single wire shape. It may be a ruler. As a result, the configuration of the ruler main body 17 is greatly simplified compared to the existing double-tracked one (for example, FIG. 17), and the amount of steel used for the ruler main body 17 is reduced and the processing amount for the ruler main body 17 is reduced. By reducing the cost and minimizing the function by simplifying the configuration of the ruler body 17, the man-hours for adjustment that should be performed at the time of construction of the rising part 4 (when placing concrete 14) can be significantly reduced. Can be done.

Further, since the ruler body 17 has a single wire shape, the ruler body 17 is not affected by the distance between the outer formwork 21 and the inner formwork 22 (for example, the width of the rising portion 4). It can be widely used when forming various risers 4 having different width dimensions 27 (corresponding to the width), and is also flexible when the riser 4 and the heat insulating material 42 are integrally constructed. It will be possible to deal with it (generalization). That is, the single-line-shaped ruler main body 17 can always be used regardless of the width dimension 27 of the rising portion 4.

Therefore, the single-wire shape anchor ruler 15 is expected to be widely used in the future because the price is lower than that of the double-line shape anchor ruler, the width handling ability and versatility are high, and the usability is good.

(Action Effect 2) The ruler main body 17 having a single wire shape may have an anchor position defining portion 31 that defines the installation position of the anchor bolt 5 on one side edge portion on the inner form 22 side. As a result, by using the anchor position defining portion 31 provided on one side edge portion on the inner form 22 side of the ruler main body 17 having a single wire shape, the outer form 21 and the inner form 22 can be separated from each other. The position where the anchor bolt 5 is installed can be easily and accurately defined.

(Action effect 3) In the anchor ruler 15, the ruler main body 17 installed at the corner portion 51 of the rising portion 4 is substantially L-shaped in plan view including the first straight line portion 53 and the second straight line portion 54 (corner ruler). 52a, 52b) may be used. As a result, by simply installing one ruler body 17 used for the corner portion 51 between the upper portions 16 of the plurality of outer formwork 21 combined to form the corner portion 51 of the rising portion 4, the corner portion 51 The outer formwork 21 to be installed at a right angle can be easily extended to keep the outer formwork 21 at a right angle, and the anchor bolt 5 can be held at an accurate position around the corner portion 51. Can be done.

Further, the diagonal member 55 may be used to connect the first straight line portion 53 and the second straight line portion 54. As a result, the strength of the L-shaped ruler body 17 installed in the corner portion 51 can be secured and improved, deformation of the ruler body 17 can be prevented, and the squareness of the ruler body 17 itself can be accurately maintained. Further, a plan view L-shaped ruler body 17 whose strength is increased by the diagonal member 55 is installed (or locked and held) between the plurality of outer formwork 21 provided to form the corner portion 51. ) Therefore, the ruler body 17 described above can firmly hold the outer form 21 for forming the corner portion 51 to prevent the outer form 21 from falling over.

(Action Effect 4) The anchor ruler 15 may be provided with connection fittings 61A and 61B for connecting between a plurality of ruler bodies 17. As a result, by connecting the plurality of ruler bodies 17 to each other using the connecting metal fittings 61A and 61B, the outer formwork is formed so that the plurality of ruler body 17s are continuous along the upper portion 16 of the outer formwork 21. It can be easily installed on the entire upper portion 16 of 21. Therefore, the outer form 21 and the ruler main body 17 can be installed with high accuracy, and the rising portion 4 can be easily finished to the design dimensions, and a plurality of anchor bolts can be attached to each part of the rising portion 4. Each of 5 can be buried with high accuracy.

The connection fittings 61A and 61B may have width dimensions 63a and 63b that match the width dimension 62 of the upper portion 16 of the outer form 21. As a result, by connecting the plurality of ruler bodies 17 using the connection fittings 61A and 61B having the width dimensions 63a and 63b matching the width dimension 62 of the upper portion 16 of the outer form 21, the outer form 21 can be simultaneously connected. The ruler body 17 can be partially held in the width direction 35 with respect to the upper portion 16. That is, the connection fittings 61A and 61B can be used as locking fittings in the width direction 35 with respect to the upper portion 16 of the outer form 21.

At this time, a plurality of types of connection fittings 61A and 61B may be prepared having different width dimensions 63a and 63b according to the width dimension 62 of the upper portion 16 of the outer form 21. As a result, a plurality of types of connection fittings 61A and 61B are used properly according to a plurality of types of outer formwork 21 having different width dimensions 62 of the upper portion 16 (that is, those having the same width dimension 63a and 63b as the width dimension 62 are selected and used. By doing so, the ruler main body 17 can be used as it is even for various outer formwork 21 having different width dimensions 62 of the upper portion 16. That is, only by preparing a plurality of types of connection fittings 61A and 61B having different width dimensions 63a and 63b, the width dimension w1 of the (single wire shape) ruler main body 17 is the width dimension of the upper portion 16 of the outer form 21. Even if it is different from 62, it can be used without any problem.
