Embodiment 1
An embodiment of the present invention will be described with reference to FIGS.
[0027]
[1] Configuration of Column Base Fixing Hardware 30
(1) The pedestal fixing hardware 30 forms the base 1 having a substantially T-shaped cross section formed by protruding the reinforcing rib 7 in the axial direction at the center of the flange 6. In the base 1, a line located on the upper surface 38 of the concrete foundation 37 to be buried is defined as a horizontal center line 4, a part buried in the foundation 37 is defined as a lower part 2, and a part protruding above the foundation is defined as an upper part 3. (FIG. 1 (b), FIG. 4 (a)). Further, the pedestal fixing hardware 30 has been subjected to a rust prevention treatment (for example, zinc plating).
[0029]
Further, an opening 8 serving as a mark of the horizontal center line 4 is formed in the flange 6 of the upper portion 3 from both side edges of the flange 6 to an intermediate portion. In the flange 6 of the upper part 3, through holes 18, 18 for fixing to the pillars 40 are arranged in parallel in the vertical direction and have different heights on the left and right. It is formed incorrectly (FIG. 1 (b)). Further, through holes 19 are formed in the reinforcing ribs 7 of the upper portion 3 for joining with the horizontal members. When the bracing is to be fixed, the upper portion 3 is extended to 3a, and a through hole 20 is formed in the flange 6 for fixing the bracing (FIG. 1C, chain lines 3a, 20). Each through hole 18, 19, 20 is formed in accordance with the shape of a fixing means to be inserted such as a bolt, a pin, a nail, or the like.
[0030]
Openings 9 and 10 formed by cutting out the entire flange 6 are formed in the middle part and the lower end part of the lower part 2, respectively. Due to the openings 8, 9 and 10, the lower part 2 of the flange 6 is divided into flange members 11, 12 and 13, which are at an angle of approximately 45 degrees from the vertical line 14 in the middle part outward ( (The side opposite to the reinforcing rib 7). Here, the bending of the flange members 11 and 12 is performed in order to eliminate the possibility of cracks in the foundation concrete and to secure a sufficient cover thickness of the concrete on the side surface portion of the foundation, and the bending angle is 30 to 90 degrees. (Better 45 to 90 degrees) is adjusted to achieve the above purpose. The lowermost flange piece 13 is a small piece, and is considered to have little effect on cracks and the like, and is not bent in order to give priority to workability when installing the column base fixing hardware 30.
[0031]
Further, along the bending line 14 of the flange member 12, circular through holes 15, 15 are bored vertically in parallel. Further, through holes 16, 16 are formed in the reinforcing ribs 7 of the lower portion 2 at a height corresponding to the flange member 12.
[0032]
The openings 8, 9, 10 and through-holes 16 connect the concrete at this point and increase the adhesion within the concrete foundation 37. In addition, the reinforcing bars 35 for the foundation can be inserted through the openings 9 and 10, so that there is no problem in the arrangement of the reinforcing bars 35 for the foundation (FIG. 1 (b), (c) chain line illustration 35). .
[0033]
(2) The column base fixing hardware 30 having the above-described configuration is formed by forming a plate material having a predetermined shape in which predetermined through holes 15, 16, 18, 19, and the like, and openings 8, 9, 10, and the like are formed in advance. Reinforcing rib pieces 7a, 7a are formed on both sides of a vertical center line (ridge line of the reinforcing rib 7), and flange pieces are formed outside the reinforcing rib pieces 7a (see FIG. 1A). By pressing the plate material, the boundary between the reinforcing rib piece 6a and the flange piece 7a is bent at 90 degrees, and then the reinforcing rib pieces 7a, 7a are bent at an angle of 90 degrees along the longitudinal center line 5, and the two reinforcing ribs are further bent. It is formed by pressing work so that the pieces 7a, 7a overlap. Therefore, the reinforcing rib 7 is formed from the stacked reinforcing rib pieces 7a, 7a, and the flange 6 is formed from the flange pieces 6a, 6a separated by sandwiching the reinforcing ribs 7a, 7a. It is desirable that the rust prevention treatment be completed in the state of the plate before bending.
[0034]
(3) Notches 22 are formed in the upper part 3 of the flange 6 and the upper part 2 of the reinforcing rib 6 with the column base fixing hardware 30 in accordance with the lower surface position of the horizontal member for securing roots (first lower horizontal member). , 23 are respectively formed, and the receiving plate 24 is attached to the notches 22, 23. The receiving plate 24 has a notch 25 that fits into the notch 22 of the flange 6 and a projection 26 that fits into the notch 23 of the reinforcing rib 6 at the center at the insertion-side edge. .
[0035]
[2] Fixed hardware 32
[0036]
The fixing hardware 32 is the same as the column base fixing hardware 30, and forms the base 1 having a substantially T-shaped cross-section formed by protruding an axial reinforcing rib 7 at the center of the flange 6. The length of the base 1 has different specifications depending on whether the upper end is fixed to the upper surface of the beam or when it is projected from the beam.
[0037]
In the fixing hardware used when joining a beam (upper horizontal member) to the side surface at the center height of the through column, a through hole for fixing the beam to the center of the reinforcing rib 7 of the base 1 is formed. The upper and lower flanges 6 are provided with through holes for fixing to the columns 40. Further, in the fixing hardware 32 used when the beam 47 is joined to the side surface of the upper end portion of the column 40, a through hole for fixing the beam 47 is formed in the upper end portion of the reinforcing rib 7 of the base 1, and a hole thereunder is provided. The flange 7 is provided with through holes for fixing it to the column 40, respectively. Each through-hole is formed in accordance with the shape of a fixing means for inserting a bolt, a pin, a nail, or the like (not shown).
[0038]
The fixing hardware 32 is formed by bending a plate material having a through hole by a press (not shown) in the same manner as the column base fixing hardware 30.
[0039]
[3] Frame structure 50
[0040]
(1) The formwork 34, 34 for the foundation is erected in accordance with the construction position of the foundation 37, and corresponds to the position of the column base fixing hardware 30 (the position of the column 40, etc.) on the formwork 34, 34 for the foundation. Then, an installation jig (not shown) temporarily fixing the column base fixing hardware 30 is temporarily fixed to the upper end portions of the base formwork 34, 34 in accordance with the blackout position. Usually, it is arranged so that one pillar 40 is sandwiched between two pillar base fixing hardware 30. Therefore, in the straight part, it arrange | positions at the opposing side surface 41,41 of the pillar 40 (FIG. 3 (a)), and arrange | positions in the corner part on the adjacent side surface 41,41 of the pillar 40 (not shown).
[0041]
In parallel with the installation of the installation jig to which the column base fixing hardware 40 is temporarily fixed, or before or after the installation jig, the reinforcing steel bars 35 for the foundation are arranged in the formwork 34. At this time, if necessary, a reinforcing bar is inserted through the openings 9 and 10 of the column base fixing metal 30, so that interference between the base reinforcing bar 35 and the lower portion 3 of the column base fixing metal 30 can be prevented.
[0042]
After that, concrete is poured into the molds 34, 34, and after solidification has developed, the mold 34 and the installation jig are removed, and the construction of the foundation 37 is completed. The upper part 3 protrudes (FIGS. 3B and 4A). If necessary, the upper surface 38 of the base 37 is trimmed.
[0043]
In the above description, the installation jig may be configured by attaching a support for supporting the column base fixing hardware 30 to a form fitting fixed to the form 34 (not shown).
[0044]
(2) Subsequently, the receiving plate 24 is inserted and attached to the column base fixing hardware 30 (FIGS. 3B and 4A). The receiving plate 24 is arranged at a position of about 5 mm from the upper surface of the foundation.
[0045]
Subsequently, the column 40 with the copper plate attached to the lower surface 42 is directly placed on the upper surface 38 of the foundation 37, and the side surface 41 of the column 40 and the flange 6 of the column base fixing metal 30 abut. , 18, a wood screw (screw) or a screw bolt is driven in to join the column base fixing hardware 30, 30 to the column 40 (FIGS. 3 (c) and 4 (b)). The column 40 is made of laminated wood, and has no cutout or mortise in the column base, so that there is no cross-sectional defect.
[0046]
In the above, since the short pillar 43 is erected in a portion where the distance between the adjacent pillars 40 is long, the pillar base fixing hardware 30, 30 is previously installed at a position corresponding to the position of the short pillar 43 in advance. The short column 43 is fixed to the column base fixing hardware 30.
[0047]
In addition, since the copper plate is sandwiched between the lower surface of the column 40 and the upper surface 38 of the foundation 37 in the above, it is possible to prevent the column 40 from absorbing moisture from the opening (lower surface 42). In addition, small irregularities are formed on the copper plate so that gaps are formed. The copper plate can be wound around the entire lower end including the lower surface, and another material can be used instead of the copper plate.
[0048]
(3) Next, between the pillars 40 or the short pillars 43, a laterally-fixing lateral member (first lower lateral member) 45 having cutouts 46 formed at both joint ends in accordance with the column-base fixing hardware 30, The notch 46 is fitted to the column base fixing hardware 30. Subsequently, a pin is driven from the side surface of the horizontal member 45 for root consolidation to penetrate the through hole 19 of the reinforcing rib 7. The upper surface of the short column 43 is formed flush with the upper surface of the horizontal member 45 for consolidation. Since the short pillars 43 are used, the length of the horizontal members 45, 45 for stiffening can be reduced to a short length (for example, 90 mm), so that the work is easy and the cost is reduced.
[0049]
(4) Subsequently, fixing hardware 32 for the beam is fixed to the intermediate portion of the column 40, and a beam 47 having a notch (having the same shape as the notch 46) formed on the joint surface between the columns 40, 40 is erected. Then, a pin is driven in from the side surface of the beam 47 to penetrate the through hole 19 of the fixing hardware 32, and the beams 47 are joined to the column 40. Similarly, beams 47 for the second floor are erected and fixed to the upper end of the column 40 via the fixing hardware 32.
[0050]
(5) Subsequently, in the portion where the wall is strengthened (the portion where structurally necessary wall rigidity is required), the columns 40, 40, the portion for enclosing the horizontal support member 45, the beam 47, and the column 40 , 40 and beams 47, 47, a wall panel 49 is fixed.
[0051]
As described above, the frame structure 50 of the present invention is constructed (FIG. 11). This frame structure 50 forms a two-story building (FIG. 14).
[0052]
(6) The above-mentioned frame structure has the same member specifications as above,
○ Structural panel: Structural plywood, thickness 9mm
○ The interval between the center pillars 40, 40: 3640 mm
○ The height between the horizontal support 45 and the beam 47 on the second floor: 5370 mm
When a horizontal load Q is applied to the second floor beam (FIG. 12),
Q = 41.0kN
Was obtained (FIG. 13).
[0053]
(7) In the above, when the bracing 52 is fixed instead of or together with the wall panel 49, bolts are inserted into the reinforcing ribs 7 into the through holes of the bracing 49 and the reinforcing ribs. (See FIGS. 5 and 9). The shape and size of the through-hole shall be suitable for the fixing means (nails, screws, bolts, etc.) used.
[0054]
[3] Another embodiment
(1) In the above embodiment, the column base fixing metal is formed by bending a plate material. However, if it can be formed in a T-shaped cross section, the flange 6 and the reinforcing rib 7 are formed as separate members by welding and integrally formed. (Not shown).
[0056]
(2) In the above embodiment, as shown in FIG. 5, the joist-receiving horizontal members 54 may be erected to form a raised floor type (FIG. 14). Also, here, the brace 52 can be inserted into the cross on the raised floor portion (see FIG. 8). Further, a wall panel 49 can be fixed to the raised floor portion instead of the bracing 52 (FIG. 16).
[0057]
(3) In the above-described embodiment, it is desirable to use the column base fixing hardware 30. However, if the column base can be fixed to the foundation 37 with the same or higher strength, another metal can be used (FIG. Not shown). Further, similarly, the fixing hardware 32 may have another structure (not shown).
[0058]
【The invention's effect】
According to the present invention, since the lower surface of the column abuts on the foundation and is fixed to each other with the column base fixing hardware, there is an effect that the base can be omitted and a strong frame structure can be constructed with a simple column base fixing metal.
[0059]
Also, when the second lower horizontal member is installed above the first lower horizontal member, a joist can be installed on the second lower horizontal member and the first floor can be constructed. Thus, the column base can be more firmly fixed to the foundation between the two horizontal members, and there is an effect that the space below the second lower horizontal member can be effectively used as a floor space.
