It is desirable that the distance D ₅ between the reinforcing rib 32 of the post-bonded metal fitting 30B and the inner surface 46a of the foundation mold 45 when contacting a is a preset size (FIG. 18). (A)).

The installation jig 96 is formed as described above (FIG. 18).

[C] Joint structure of foundation and pillar

(1) The flange portion 31 of the post-bonding metal piece 30B is brought into contact with the fixing plate 102 of the installation jig 96, the holding notches 18 and 18 are aligned with the screw holes 103 and 103, and the butterfly bolt 110 is screwed. It is screwed and tightly connected to the hole 103, and the column-joined metal fitting 30B is attached to the installation jig 96 (FIG. 19).
(A)). At this time, the reinforcing ribs 3 of the pillar-joined metal fitting 30B are attached to the center lines 97a, 97a of the base body 97 (that is, the center lines of the pillars).
It is attached so that the positions of 2 are the same (Fig. 18).
(A)).

(2) As in Example 2, the ground is leveled,
At the planned foundation construction position where the discarded concrete was struck, a predetermined marking is made on the discarded concrete. In addition, the stake out is generally a concrete foundation 50 to be constructed.
Distribute from the center line of (cloth foundation) and hit the form line.

Subsequently, the side plate 46 on the outside of the form is assembled on the discarded concrete in accordance with the marking position. Further, in this embodiment, a steel form having a height of 600 mm is adopted, but the height and the material are appropriately selected and used according to the foundation 50 to be constructed. Further, the present invention can be applied in the same procedure (not shown) even if an auxiliary mold is appropriately added to the upper surface of a ready-made steel mold and used.

(3) The laser beam leveler is positioned on the inner surface of the side plate 46 in accordance with the position of the upper surface 51 of the foundation 50 to be constructed, and is connected to draw the line of the upper surface 51. Then, the height H is above the line of the upper surface 51.
_A line is drawn at the position of ₅ (here, H ₅ = 50 mm).

Next, the stopper 111 made of wood chips is fixed to the inner surface 46a of the side plate 46. At this time, the upper surface 112 of the stopper 111 is aligned with the line of height H ₅ (FIG. 19A). The stopper 111 is fixed by, for example, screwing a hook screw toward the stopper 111 from the outer surface 46b side of the side plate 46. At this time, the side plate 4
It is desirable to preliminarily form a through hole through which the hook screw can pass (not shown).

(4) The reinforcing bars for the foundation are arranged in the usual manner, and the side plates inside the formwork are assembled (not shown).

(5) Subsequently, the installation jig 9 in which the column-joining metal fittings 30B, 30B are attached in the mold 45 at the corner portion.

At this time, the lower portion 2 of the pillar-joined metal fitting 30B is inserted between the reinforcing bars for corners, and the basic reinforcing bars can be inserted into the locking notches 15 and 15 of the lower portion 2.
In addition, since it is possible to omit the metal fixtures for fixing the base other than the pillar-joint metal fittings 30B, the anchor bolts, etc., only the pillar-joint metal fittings 30B are inserted between the corner reinforcing bars, and each member does not interfere in the formwork. The rebar and the post-bonding metal fitting 30B can be easily accommodated.

(6) Subsequently, the positions of the center lines 97a and 97a of the installation jig 96 are aligned with the positions of the columns to be constructed. That is, the position of the reinforcing rib 32 of the pillar-bonded metal 30B is
Align it with the position of the pillar that was planned to be built in advance.

When the alignment is completed, the side plate 46 and the guide protrusion 107 are fixed by screwing a hook screw or the like toward the guide protrusion 107 from the outer surface 46b side of the side plate 46.
At this time, if a gap is formed between the inner surface 46a of the side plate 46 and the end surface 108 of the guide protrusion 107, spacers are appropriately interposed (not shown). Also in this case, it is desirable that the side plate 46 is previously provided with a through hole through which the hook screw can pass (not shown).

(7) Next, concrete is poured into the corner mold 45 and other molds. At this time, it is desirable that the concrete is cast in several times or quietly so that the position of the column-joined metal 30 is not displaced in the corner portion.

(8) After the concrete has solidified, the butterfly bolts 110, 110 are removed, and the installation jig 96 is removed from the column-joining metal parts 30B, 30B (FIG. 20 (b)).
When the stopper 111, the form 45, and other forms are removed, the concrete foundation 50 is constructed. At this time, the upper portion 3 of the pillar-bonded metal piece 30, 30 projects from the upper surface 51 of the foundation 50 (see FIG. 4).

In the above, a drainer 52 is formed on the outer peripheral side of the upper surface 51 of the foundation 50 (FIG. 20 (b), FIG. 21).
The drainer 52 makes it difficult for rainwater to collect on the upper surface 51 of the foundation 50, and makes it difficult for the pillars and the base to absorb the rainwater.
It can be formed by attaching a rod-shaped magnet in advance at a planned construction position on the inner surface 46a of the side plate 46 on the outer side of the foundation formwork and pouring concrete (not shown).
Further, instead of the rod-shaped magnet, a steel rod may be fixed by a magnet or other means, or wood or resin material having a similar shape may be used.

(9) Then, similarly to the second embodiment, the copper plate 56 is attached to the lower end portions of the lower surface 54 and the side surface 55 of the column 53 to be used.
And the lower end (column base) of the column 53 is placed directly on the upper surface 51 of the foundation 50 (without the base) (see FIG. 5,
Figure 21). At this time, the side surface 55 of the pillar 53 and the pillar-joint metal 30

[D] Other Embodiments

(1) In the installation method of the above embodiment,
Although the stopper 111, the guide protrusion 107, and the side plate 46 are fixed by hook screws, they may be fixed by other screws or nails, or by other commonly used means (not shown). Further, although the stopper 111 is made of a piece of wood, it may be made of a block magnet. In this case, the stopper 111 is attached and held to the steel side plate 46 without using other fixing means. You can also do it.

Although the installation jig 96 is used in the installation method of the above-described embodiment, the attachment jig 34 or the like can be used as in the second embodiment (not shown). Further, although the pillar-bonded metal fitting 30B is used, the pillar-bonded metal fitting structure of the foundation and the pillar is constructed by the same installation method using the pillar-bonded metal fittings 30, 30A, 48, 80 and the like of the above-mentioned Examples 1 and 3. It can also be configured (not shown).

(2) In the pillar-bonded metal piece 30B of the above-described embodiment, a through hole can be formed instead of the holding notch 18 (not shown). Further, other examples of the other post-bonded metal fittings are the same as the above-mentioned Examples 1, 3, and 4.

Further, in the pillar-joint metal fitting 30B, the width of the lower portion 2 of the flange portion 31 is made narrower than that of the upper portion 3 because the width 2 × D ₀₂ of the lower portion 2 of the flange portion 31 has a predetermined concrete cover thickness. This is because it was made as small as possible so that it could be secured. Therefore, when the plate material 1 made of a zinc steel plate is used as in the present embodiment, rust is unlikely to occur, so that an excessive cover thickness is not necessary, and the width of the lower portion 2 of the flange portion 31 is set to the upper portion. In this case, the steps 29, 29 may be omitted, and the pillar-shaped metal fitting 30B of Embodiment 1 may be formed (FIGS. 1 to 3).

(3) In the installation jig 96 of the above embodiment, the end surface 108 of the guide protrusion 107 is the side plate 4 of the form 45.
If it can contact the inner surface 46a of 6, the locking protrusion 104 has a width D.
It is also possible to form it shorter than _{4 and} to form it so as not to contact the inner surface 46a of the mold 45 (not shown).

Further, in the installation jig 96 of the above embodiment, the installation jig 96 is constructed by combining the block-shaped stopper 111 of the mold 45 and the block-shaped locking projection 104 placed thereon. Although held at a predetermined position, if the installation jig 96 can be held at a predetermined position from concrete pouring to solidification manifestation, the stopper 111 and the locking projection 104 are held.
The shape of is arbitrary.

Further, in the installation jig 96, the guide projection 107 has a block shape, but the side plate 46 of the mold 45 is different.
Other shape structures (not shown) can be used as long as they can abut the inner surface 46a.

Further, in the installation jig 96, one corner of the base body 97 is chamfered 100, so that the rebar of the corner of the form 45 can be visually observed from the chamfered portion 100.
Although preferred, the chamfer 100 may not be formed (not shown).

In the installation jig 96, the fixing plate 102 is made of metal, but it may be made of resin or wood having high hardness. Further, the screw hole 103 can be formed directly on the side surface of the base body 97 without using the fixing plate 102.

Further, in the installation jig 96, the pillar-joint metal 30B is attached using the butterfly bolt 110, but other bolts may be used (not shown). Further, various pins can be used, and in this case, instead of the screw hole 103, a hole for a pin is formed (not shown).

Further, through holes 57, 57 for driving screws for fixing the base are formed on the other edge side of the plate material to form a base metal receiving object 76 (FIG. 25).

[C] Joint structure of foundation and pillar

(1) Installation jig 96 as in the fifth embodiment
(See FIG. 18). Fixing plate 1 for installation jig 96
The flange portion 31 of the pillar-joined metal piece 30 is brought into contact with 02, the holding notches 18, 18 and the screw holes 103, 103 are aligned with each other, and the butterfly bolt 110 is screwed and tightly connected to the screw hole 103, so that the pillar-joined metal piece 30 is fixed. Attach to the installation jig 96 (Fig. 27)
(A) (b)). At this time, the reinforcing ribs 32 of the pillar-joined metal fitting 30 are attached so that the positions thereof coincide with the center lines 97a, 97a of the base body 97 (that is, the center lines of the pillars) (FIG. 27).
(A)).

(2) As in the second embodiment, the ground is leveled,
At the planned foundation construction position where the discarded concrete was struck, a predetermined marking is made on the discarded concrete. In addition, the stake out is generally a concrete foundation 50 to be constructed.
Distribute from the center line of (cloth foundation) and hit the form line.

Subsequently, the side plate 46 on the outside of the form is assembled on the discarded concrete in accordance with the marking position. Further, in this embodiment, a steel form having a height of 600 mm is adopted, but the height and the material are appropriately selected and used according to the foundation 50 to be constructed. Further, the present invention can be applied in the same procedure (not shown) even if an auxiliary mold is appropriately added to the upper surface of a ready-made steel mold and used.

(3) A laser beam leveler is used to position the inner surface of the side plate 46 in accordance with the position of the upper surface 51 of the foundation 50 to be constructed, and tie it to draw a line on the upper surface 51. Then, the height H is above the line of the upper surface 51.
_A line is drawn at the position of ₅ (here, H ₅ = 50 mm).

Next, the stopper 111 made of wood chips is fixed to the inner surface 46a of the side plate 46. At this time, the upper surface 112 of the stopper 111 is aligned with the line of height H ₅ (see FIG. 19A). The stopper 111 is fixed by, for example, screwing a hook screw toward the stopper 111 from the outer surface 46b side of the side plate 46. At this time, it is desirable to previously form a through hole through which the hook screw can pass in the side plate 46 (not shown).

(4) Reinforcing bars for the foundation are arranged as usual, and side plates inside the formwork are assembled (not shown).

(5) Subsequently, the installation jig 96 having the column-joining metal parts 30, 30 attached is inserted into the corner frame 45, and the locking projections 104, 104 of the installation jig 96 are
If placed on the upper surface 112 of the stoppers 111, 111,
The pillar-bonded metal parts 30, 30 are installed at a predetermined height in the mold 45 (see FIG. 19B).

At this time, the lower portion 2 of the pillar-joined metal 30 is inserted between the corner reinforcing bars, and the basic reinforcing bars can be inserted into the locking notches 15 and 15 of the lower portion 2. In addition, since it is possible to omit the metal fixtures for fixing the base other than the pillar-joint hardware 30, anchor bolts, etc., only the pillar-joint hardware 30 is inserted between the corner rebars, and each member does not interfere in the formwork. The rebar and the pillar-joint metal fitting 30 can be easily accommodated.

(6) Then, the positions of the center lines 97a and 97a of the installation jig 96 are aligned with the positions of the columns to be constructed. That is, the positions of the reinforcing ribs 32 of the pillar-joined hardware 30 are aligned with the positions of the pillars to be constructed which have been marked out in advance.

When the alignment is completed, the side plate 46 and the guide protrusion 107 are fixed by screwing a hook screw or the like toward the guide protrusion 107 from the outer surface 46b side of the side plate 46.
At this time, if a gap is formed between the inner surface 46a of the side plate 46 and the end surface 108 of the guide protrusion 107, spacers are appropriately interposed (not shown). Also in this case, it is desirable that the side plate 46 is previously provided with a through hole through which the hook screw can pass (not shown).

(7) Next, concrete is poured into the corner mold 45 and other molds. At this time, it is desirable that the concrete is cast in several times or quietly so that the position of the column-joined metal 30 is not displaced in the corner portion.

(8) After the concrete has solidified, the butterfly bolts 110, 110 are removed, and the installation jig 96 is removed from the column-joining metal parts 30, 30 (see FIG. 20 (b)).
When the stopper 111, the form 45, and other forms are removed, the concrete foundation 50 is constructed. At this time, the upper portion 3 of the pillar-bonded metal piece 30, 30 projects from the upper surface 51 of the foundation 50 (see FIG. 4).

In the above, the drainer 52 is formed on the outer peripheral side of the upper surface 51 of the foundation 50 (see FIG. 20 (b), FIG. 21).
reference). The drainer 52 makes it difficult for rainwater to collect on the upper surface 51 of the foundation 50, and makes it difficult for the pillars and the base to absorb the rainwater. On the inner surface 46a of the side plate 46 on the outer side of the foundation formwork,
It can be formed by attaching a rod-shaped magnet in advance at the planned construction position and pouring concrete (not shown). Further, instead of the rod-shaped magnet, a steel rod may be fixed by a magnet or other means, or wood or resin material having a similar shape may be used.

(9) Then, similarly to the second embodiment, the copper plate 56 is provided on the lower end 54 of the lower surface 54 and the side surface 55 of the column 53 to be used.
And the lower end (column base) of the column 53 is placed directly on the upper surface 51 of the foundation 50 (without the base) (see FIG. 5,
See FIG. 21). At this time, the side surface 55 of the pillar 53 and the flange portion 31 of the pillar-joined metal piece 30 come into contact with each other, and a screw (or a screw bolt) is driven through the through holes 25, 25 of the flange portion 31 to connect the pillar-joined metal piece 30 and the pillar 53. Join (see FIG. 5).

(10) Subsequently, the tip of the horizontally placed metal receiving object 76 is brought close to the column-bonding metal object 30 (FIG. 25).
The reinforcing rib 32 is inserted into the notch groove 79 of the metal receiving object 76, and the protrusions 87 and 87a of the metal receiving object 76 are inserted into the notches 75a and the through holes 75b of the column joint metal object 30, respectively.

With the projections 87, 87a of the receiving object 76 in contact with the side surface 55 of the pillar 53, the base end of the receiving object 76 is hit with a hammer or the like to strike the projections 87, 87a of the receiving object 76 into the pillar 53. . At this time, the protrusions 87, 87a of the receiving object 76
Since the tip is formed in a convex taper shape, it is guided to the notch 75a and the edge of the through hole 75b of the post-joint metal fitting 30, and is easily driven into the post 53 at the correct position.

The remaining part 75c of the pillar-bonded metal object 30 is driven into the recess 8 of the metal object 76 by being driven.
7b, the bottom 79a of the cut groove 79 of the receiving object 76
Is engaged with the notch groove 75 of the reinforcing rib 32 of the pillar-joined metal fitting 30, and the metal receiver 76 is integrated with the pillar-joined metal fitting 30 into the pillar 53.
Fixed to.

(11) In this way, the adjacent pillars 5 are
The pillar-bonding hardware 30, 30 is fixed to the side surfaces 55, 55 of the column 3, respectively, and the receiving metal 76 is fixed to each of the pillar-bonding hardware 30 (side surface 55 of the pillar 53) (FIGS. 28 (a) (b)). . In addition, the corner 50 of the foundation 50 has the same structure (FIG. 28).
(C)). In this case, in the pillar 53 at the corner, the flange 31 of the pillar-joined metal piece 30 is fixed to the adjacent side surfaces 55, 55, respectively. In this case, the through hole 2 formed in the flange 31 is used.
Since 5 and 25 are arranged in a zigzag pattern, there is no possibility that the screws, which are inserted into the through holes 25 and are punched into the pillars, interfere with each other in the both-column joint metal pieces 30 and 30.

Subsequently, bases 58 and 58 (see FIG. 5) having notches 62 are installed between the pillars 53 and 53, and the base 5
The lower surfaces 59a, 59a of both end portions of 8 are placed on the receiving object 76. At this time, the reinforcing ribs 42 of the post-joined metal fitting 30 are fitted into the notches 62 of the base 58 (see FIG. 6).

Then, a through hole 61 (FIG.
A pin (not shown) is driven into the through hole 26 of the reinforcing rib 32 of the post-joint metal fitting 30, and a square nail or a flat nail (not shown) is inserted into the through-hole 74 of the post-joint metal fitting 30. ) Is inserted and driven into the side surface 55 of the pillar 53, the other end of the square nail is driven into the upper surface 59 of the base 58, and the concrete base 50, the pillar 53, and the base 58 are integrated via the pillar-joined metal 30. Is joined to (Fig. 28 (a))
(B)). At this time, by using nails in addition to the pins, it is possible to increase the pulling-out proof strength of the column-joint metal fitting 30, so it is preferable to use both, but it is also possible to use either the pins or the nails. . Further, a gap having a height H ₂ is formed between the lower surface 59a of the base 58 and the upper surface 51 of the foundation 50 (FIG. 28 (a)).

(12) Subsequently, the lower ends of the braces 63 are arranged along the reinforcing ribs 32, and the through holes 27, 27 of the reinforcing ribs 32 are formed.
Drive a screw toward the braces 63 to make the braces 63
Through the pillar-jointed metal fittings 30 to the concrete foundation 5
0, pillar 53, and base 58 are integrally joined (see FIG. 28).
(A)).

[D] Other Embodiments

(1) In the above embodiment, the braces 63
The column-joined metal fittings that are used to fix the
For both 1 and the reinforcing rib 32, it is also possible to use the pillar-joined metal fitting 30A that is formed in a short shape in accordance with the upper surface 59 of the base 58 using the upper portion 3 (FIGS. 26A and 26B). In this case, the shape of the plate material 1 used for manufacturing the pillar-bonded metal fitting 30A is also shortened in correspondence with the upper portion 3 (not shown), but the installation method (attachment to the installation jig 96) is the same. is there.

(2) In addition, in the above-mentioned embodiment, if there is no obstacle in the bar arrangement of the concrete foundation 50, the opening 2

Seventh Embodiment Another embodiment of the present invention will be described with reference to FIGS. In each of the above examples, among the steel materials for construction,
The column-joining metal used for joining the foundation and the column has been described, but it is an example of a building steel material for other uses.

[A] Manufacture of architectural steel 115

(1) A vertically long rectangular plate material (for example, a zinc steel plate having a thickness of 2.3 mm) 1, a portion having a predetermined width D ₀ (about D ₀ = 35 mm) from the left and right side edges 5 and 6 is a predetermined flange portion 7. , 8 and the vertical lines (the side edges of the flange planned portions 7 and 8) located at the width D ₀ from the left and right side edges 5 and 6 are the first folding line 11 and the second folding line 12, respectively.

The center from the left and right side edges 5 and 6 of the plate material 1 is defined as a vertical center line 10, and the inner side of the first fold line 11 or the second fold line 12 on both sides of the vertical center line 1 is a reinforcing rib. Scheduled sections 13 and 14 will be used. The distance between the vertical center line 10 and the first folding line 11 or the second folding line 12, that is, the reinforcing rib planned portion 13,
The width of 14 is D ₁ (D ₁ = about 55 mm) (FIG. 35).
(A)).

(2) At both ends of the plate material 1, through holes 24, 24 for joining are formed in the planned flange portions. The through holes 24, 24 of both flange planned portions 7, 8 are formed symmetrically with respect to the longitudinal centerline 10. Further, at both end portions of the plate member 1, the through holes 2 are also formed in the rib preliminarily strips 13 and 14 symmetrically with respect to the vertical center line 10.
8 and 28 are drilled. The plate material 1 having the above-described shape is integrally formed by press working (FIGS. 35 (a) and 35 (b)).

(3) Subsequently, the plate material 1 is processed in the same manner as in Example 1.

That is, the plate material 1 is folded along the fold lines 11 and 12, the planned flange portions 7 and 8 are folded toward the front surface 1a (folded so as to be convex toward the rear surface 1b side), and the planned flange portions 2 and 8 and the reinforcing ribs are planned. Bending is performed so that the portions 13 and 14 are at a right angle (FIG. 35 (c)). After the processing, the planned flange portions 7 and 8 are formed substantially parallel to each other.

Subsequently, the plate material 1 is folded along the vertical center line 10 so as to be convex toward the front surface 1a, and both the reinforcing rib planned portions 1 are formed.
The plates 3 and 14 are formed in a V shape, and the entire plate 1 is formed in a substantially M shape (inverted W shape) (FIG. 35 (d)).

Then, the both planned reinforcing ribs 13 and 14 are pressed so as to overlap each other. As a result, both flange planned parts 7 and 8
Is formed in a flat plate shape, and the flange portion 30 is composed of both flange planned portions 7 and 8. Further, the reinforcing rib 31 is composed of the overlapping portions of the reinforcing ribs 13 and 14 which are overlapped with each other. Above,
The construction steel material 115 having a T-shaped cross section in which the flange portion 31 and the reinforcing rib 32 are arranged at a right angle is configured (FIGS. 36 and 3).
5 (d)).

[B] Use of building steel material 115

(1) The building steel material 115 thus formed can be used, for example, by laterally arranging it as a large floor pull (FIG. 30). In this case,
It is used by being erected and fixed between the steel bundling members 117 and 117 formed so as to be vertically movable by the upper and lower bolt shafts 116 and 116. In this case, the building steel material 115 is arranged with the reinforcing ribs 32 facing downward, and the through holes 28 of the reinforcing ribs 32 of the building steel material 115 are arranged.
Then, the bolt 119 is inserted into the through hole of the angle member 119 at the upper end of the steel bundle 117 and is fixed with the nut 120 (FIG. 30 (b)). Since the bundling member 117 is made of steel, the building steel material 115 as a large pull can be easily joined. In addition, a nail or the like is driven into the flange portion 31 of the building steel material 115 from the through holes 24, 24 to previously fix the wood piece 121, and the wooden joist 122 is erected and fixed to this (FIG. 30 (a)).

Ninth Embodiment Another embodiment of the present invention will be described with reference to FIGS. 38 and 39. In this embodiment, the beams 81 and the tube columns 13 are mainly used.
The present invention relates to a building steel material 115 used for joining with 9.

[A] Manufacture of architectural steel 115

(1) With a vertically long rectangular plate material (for example, a zinc steel plate having a thickness of 2.3 mm) 1, a portion having a predetermined width D ₀ (about D ₀ = 35 mm) from the left and right side edges 5 and 6 is a planned flange portion 7. , 8 and the vertical lines (the side edges of the flange planned portions 7 and 8) located at the width D ₀ from the left and right side edges 5 and 6 are the first folding line 11 and the second folding line 12, respectively.

The center from the left and right side edges 5 and 6 of the plate 1 is defined as a vertical center line 10, and the inner side of the first fold line 11 or the second fold line 12 on both sides of the vertical center line 1 is a reinforcing rib. Scheduled sections 13 and 14 will be used. The distance between the vertical center line 10 and the first folding line 11 or the second folding line 12, that is, the reinforcing rib planned portion 13,
The width of 14 is D ₁ (D ₁ = about 55 mm) (FIG. 38).
(A)).

(2) At both ends of the plate material 1, the rib-preliminary piece 1
Through holes 137 and 137 for attachment (for pin insertion) are bored in 3 and 14 symmetrically with respect to the vertical center line 10. In addition, at both end portions of the plate material 1, the longitudinal centerline 1
Through hole 13 for mounting (for inserting screws) symmetrical to 0
8, 138 are drilled. Plate material 1 having the above shape
Are integrally formed by press working (FIG. 38 (a)).
(B)).

(3) Subsequently, the plate material 1 is processed in the same manner as in Example 1.

That is, the plate material 1 is folded along the folding lines 11 and 12, and the planned flange portions 7 and 8 are folded toward the front surface 1a (folded so as to be convex toward the rear surface 1b), and the planned flange portions 7 and 8 and the reinforcing ribs are planned. A bending process is performed so that the portions 13 and 14 are at a right angle (FIG. 38C). After the processing, the planned flange portions 7 and 8 are formed substantially parallel to each other.

Subsequently, the plate material 1 is folded along the vertical center line 10 so as to be convex toward the front surface 1a, and both the reinforcing rib planned portions 1 are formed.
The plates 3 and 14 are formed in a V shape, and the entire plate material 1 is formed in a substantially M shape (inverted W shape) (FIG. 38 (d)).

Subsequently, the both reinforcing rib planned portions 13 and 14 are pressed so as to overlap each other. As a result, both flange planned parts 7 and 8
Is formed in a flat plate shape, and the flange portion 31 is composed of both flange planned portions 7 and 8. In addition, the reinforcing ribs 32 are formed by the overlapping portions of the reinforcing ribs 13 and 14 which are overlapped with each other. Above,
The flange portion 31 and the reinforcing rib 32 are arranged at a right angle to form a building steel material 115 having a T-shaped cross section (FIGS. 39 and 3).
8 (d) (e)). In addition, overlapping reinforcement ribs 1
The through holes 137 and 137 communicate with each other at 3 and 14.

[B] Use of building steel 115

(1) The building steel material 115 thus formed is used, for example, for joining the beam 81 and the pipe column 139.

A housing portion 141 corresponding to the flange portion 31 and a housing portion 142 corresponding to the reinforcing ribs 32 are formed on the lower surface 140 of the pipe column 139 used for joining so that the building steel material 115 can be housed therein. . Further, a through hole 143 through which the pin 144 is inserted is formed (FIG. 39 (a)).

On the upper surface 82a of the beam 81, the lower surface of the flange portion 31 of the steel material 115 for construction is brought into contact with the position where the tube column 139 is fixed, and screws are dropped from the through holes 138 and 138 (FIG. 39 (b)). , The beam 81 and the building steel material 115 are joined (FIGS. 39 (a) (c)). Then, at the joining position of the beam 81, the housing 141, so as to cover the building steel material 115,
The tube column 139 is erected on the beam 81 while being accommodated in 142.

(2) Then, the through hole 14 of the tube column 139.
The pin 144 for joining is fitted in 3 and the through holes 137 and 137 of the reinforcing rib 32 are penetrated. As described above, the beam 81 and the tube column 139 are joined to each other through the building steel material 115.

(3) In the above, the upper surface 82 of the beam 81
Although the example in which the lower surface 140 (tree end) of the pipe pillar 139 is joined to a (side surface) has been described, the joint structure in which the side surface of one member is joined to the mouth end of another member is also applied to other joint portions. Can be used. For example, it can be used to join a shed beam and a shed bundle, a beam and a stud, a post and a bridge (not shown).

If the building steel material 115 is made strong (thick material is thick and the reinforcing ribs 32 are large), it can be used for joining a base and a through column (not shown).

[0236]

As described above, according to the present invention, the locking portion of the horizontal reinforcing bar for the foundation is formed in the lower portion, and the column-joining metal article capable of fixing the column and the braces is formed in the upper portion. If buried, there is an effect that the column and the braces can be structurally and integrally joined to the concrete foundation.

When a reinforcing rib is integrally connected to one surface of the flange portion of the pillar to form a substantially T-shaped plane, and the pillar-joined metal article is constructed, the flange portion is attached and fixed to the pillar. , It has the effect of firmly joining the foundation and the pillar. Further, in this case, there is an effect that the reinforcing rib can be utilized as a fixing member for bracing.

Therefore, especially if the lower part of the pillar-bonded metal is buried in the corner part of the concrete foundation,
It is possible to secure the required adhesion cover thickness with concrete and to easily store it without interfering with the pillar-joining metal fittings that join the reinforcing bars for the foundation and the pillar that is the upper structure.

Further, since the lower surface of the column can be directly joined to the upper surface of the concrete foundation, the column base is fixed and the function of the base as a structure for bearing the load is reduced, so that the cross section of the base is reduced. Alternatively, the base can be made of a weak material. Further, the base itself may be omitted in the portion where the wall or floor is not constructed. Therefore, it is possible to omit the base that has conventionally required high-strength structural wood, and to use a base such as thinned wood or laminated wood,
The effect is that effective use of resources can be realized.

[0240] Further, both end portions of a plate material having a predetermined through hole or the like are bent at right angles to form a flange planned piece, and a central portion is bent into a V shape to form two reinforcing rib planned pieces. After that, when further bending is performed so that the central portion overlaps with each other to construct a steel material for construction such as a flat T-shaped pillar-joint metal fitting, the pillar-joint metal fitting can be manufactured only by a pressing step, which facilitates mass production. effective. Further, since the reinforcing ribs can be formed by stacking two plate materials, there is an effect that a structurally stronger pillar-jointed metal product can be formed as compared with the thickness of the plate materials. In addition, since it can be manufactured by pressing using a plate material that has been processed with through holes etc. and subjected to rust prevention in advance, it is possible to eliminate the rust prevention process after product completion and reduce the manufacturing cost There is.

Further, by using the installation jig having a cross section substantially the same as the pillar to be constructed, and attaching the pillar-jointing metal piece to this in a detachable manner and holding it in the formwork, the pillar-jointing metal piece is placed at a predetermined position. There is an effect that it can be installed easily and accurately.
