Description

  The present invention relates to a reinforcing member for a column and a horizontal member, and more specifically, includes a first plate fixed in contact with the outer surface of the column and a second plate fixed in contact with the outer surface of the horizontal member. The present invention relates to a reinforcing member for a column and a horizontal member using a hardware having the metal member, and a joining structure of the column and the horizontal member using the reinforcing member.

  Nowadays, which is said to be an active period of earthquakes, there is a high interest in housing safety. In conventional wooden buildings, in order to improve safety and earthquake resistance, bracing members are arranged diagonally from the joints of horizontal members perpendicular to the pillars to the joints, or earthquake resistant walls using structural plywood are installed. There are methods of disposing them, or placing a firewood or a cane.

  However, if a seismic wall using bracing or structural plywood is placed diagonally between the column and the horizontal member, it will be difficult to provide a window or doorway. If it is preferentially provided, it becomes difficult to dispose a seismic wall using bracing material or structural plywood. In addition, seismic walls using bracing and structural plywood must be placed in a well-balanced manner throughout the wooden building, thus limiting the plan plan. Moreover, it cannot be said that the strength of the joint is sufficient with a wooden wand.

  Therefore, it is known to use hardware for reinforcement. Generally, as shown in Patent Document 1, there is a method of attaching an L-shaped hardware to a joint portion of a horizontal member orthogonal to a column. The method of attaching the L-shaped hardware to the joint portion of the horizontal member orthogonal to the pillar is not preferable in design because the metal is exposed as an external appearance, although the attachment is easy. In addition, this is a substitute for wooden bracing, and there is a problem that the reinforcing strength is limited.

  Therefore, as shown in Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5, there is a method of using a metal object embedded in a horizontal member. The method shown in Patent Document 2 and Patent Document 3 is a method with high design that increases the bonding strength between the pillar and the horizontal member, and can be used by processing a domestic material pillar or horizontal member, There is a problem that the bending moment due to the horizontal force of the joint is incompatible. For horizontal moments during earthquakes and typhoons, it is necessary to install braces and wands to increase resistance stress. The method shown in Patent Document 4 and Patent Document 5 is a rigid connection method, and is manufactured by embedding hardware in a pillar or horizontal member made of structural laminated material, and the hardware is not exposed, so that the design is possible. Is expensive. In addition, large span wooden structures can be constructed.

JP 2002-38588 A Japanese Patent Laid-Open No. 10-25811 JP 2005-200907 A JP 2013-57168 A Japanese Patent No. 5682057

  However, since the process of embedding the hardware shown in Patent Document 4 and Patent Document 5 described above in a horizontal member is complicated, it requires processing at a processing plant having a special machine, such as a small factory or construction site. It cannot be easily processed. In addition, there is a problem that the cost is high. In addition, the “Law on the Promotion of the Use of Wood in Public Buildings” aimed at realizing a 25% reduction in CO2 was promulgated on May 26, 2010, and the promotion of the use of domestic timber in public buildings was encouraged. However, the method of embedding the hardware shown in the above-mentioned Patent Document 4 and Patent Document 5 in the pillar and the horizontal member is that the pillar and the horizontal member are mainly constructed of a structural laminated material, Structural laminated wood is mainly made from foreign materials, and the proportion of domestically used materials is low. In addition, it is optimal for large public buildings, but not suitable for residential or small-scale buildings. When using horizontal members and columns that do not embed hardware (conventional wooden frame construction method, which is one of the conventional methods), the horizontal members and columns are tenon and tenon (here, through holes and holes) This is a pin joint that is joined using bolts and the horizontal force is borne by braces, etc., but this pin joint is utilized and braces, etc. In order to improve safety and earthquake resistance without using steel, it is necessary to consolidate the joint with reinforcing hardware. Also, a larger bending moment due to the vertical force acts on the center of the pin-joint horizontal member than in the rigid joint. Since this bending moment is proportional to the square of the length of the horizontal member, the portion near the center of the horizontal member is supported by the reinforcing member, and the distance between the fulcrum of the horizontal member is shortened to bend the horizontal member. It is necessary to increase the moment resistance. In addition, when an earthquake or strong wind receives a large load in the lateral direction and there is no bracing, a bending moment is generated at the joint between the column and the horizontal member or the column. In such a case, the column bending moment is strengthened by reinforcing the joint between the column and the horizontal member with a reinforcing member and providing a long reinforcing member so as to be as long as possible from the joint between the column and the horizontal member. It is necessary to increase resistance and prevent column breakage.

  Therefore, L-shaped hardware can be considered as a candidate for a reinforcing member that can be easily attached at a construction site. However, although it is possible to make the metal object rigid by adding a reinforcing rib or the like, the support point of the horizontal member cannot be brought close to the center of the horizontal member unless the dimension of the L-shaped metal object is increased. However, if the dimension of the L-shaped hardware is lengthened, there is a problem that the hardware is exposed and the design is deteriorated. In addition, since the hardware is manufactured by a mold, welding, or the like, it is not easy to change the length of the reinforcing member as appropriate according to the mounting location.

  The present invention makes it possible to attach hardware on a construction site without embedding it in a horizontal member, increase the reinforcement strength, contribute to the promotion of the use of wood, have a decorative face of wood, and maintain the design of the use location, It is an object of the present invention to provide a reinforcing member for a column and a horizontal member that can easily change the length of the reinforcing member as appropriate.

  In order to achieve the above object, the column and horizontal member reinforcing member according to the present invention includes a first plate that contacts the outer surface of the column, extends to a predetermined support point, and is fixed to the column. A first hardware having a second plate abutting on the outer surface of the plate and extending to a predetermined support point and fixed to the horizontal member, wherein the first hardware is a support point of at least one of the column and the horizontal member. An attachment portion for attaching an additional reinforcing material for extending the wire is provided.

Both the first hardware and the second hardware are in contact with only the outer surface of the pillar and the horizontal member. Therefore, the present invention can solve the problem that, as in Patent Documents 2, 3, 4, and 5, since the reinforcing member is embedded in the wood, complicated processing of the wood must be performed in the factory in advance. Moreover, the cross-sectional defect | deletion by the process for embedding a reinforcement member in a timber can be decreased. In addition, even existing wooden buildings can be easily reinforced. In addition, by attaching the first hardware and the second hardware, the joint between the column and the horizontal member can be consolidated, and the support points of the column and the horizontal material can be extended to a predetermined support point. Corresponding vertical stress at the horizontal member at the opposite ends pin joints between columns (beams), the maximum bending moment WL ^2/8 at the center portion of the horizontal member (beam) (W is the vertical load on the horizontal member, L is the length between the support points of the horizontal member between the corresponding columns), so in the present invention, if an additional reinforcing material is attached and the support point of the horizontal member is extended (see X1 → X2 in FIG. 8), The length between support points (L) in which the bending moment of the horizontal member is proportional to the square of the length between the horizontal member support points can be shortened, and the effective increase of the bending moment resistance of the horizontal member Become. If an additional reinforcing material is attached to the column and the supporting point of the column (see Y1 → Y2 in FIG. 8) is extended, the section modulus of the Y2 point portion of the column is increased by the reinforcing material fixed to the column. The bending moment resistance of the column due to the force (wind, seismic force) will increase. In addition, using the same first hardware, it is possible to easily change the support position of the pillars and horizontal members simply by changing the dimensions of the reinforcing material according to the location of the building or the reinforcing member. it can. For example, a short reinforcing material may be used in a place where only a small amount of reinforcement is required, and a longer reinforcing material may be used in a place where a large amount of reinforcement is required. The material of the reinforcing material may be wood or a composite material (wood strength equivalent product) whose surface is injection-molded with FRP (fiber reinforced plastic), but if it is made of wood, it is easy to change the size of the reinforcing material because no mold is required. .

  In the column and horizontal member reinforcing member of the present invention, a third plate that abuts the outer surface of the horizontal member and clamps the horizontal member with the second plate, and an outer side of the column. A second metal fitting having a fourth plate abutting on the surface and fixed to the column is provided.

  Since the horizontal member is sandwiched between the first hardware and the second hardware, the fixing force of the first hardware to the horizontal material is increased, and the horizontal material is prevented from being split. In addition, since the first and second hardware that sandwich the horizontal member are both fixed to the pillar, the tenon of the horizontal member that is pin-joined by covering and other methods as a conventional wooden shaft construction method is used as the pillar. The joint portion bending moment resistance is increased by the fitting joint effect that bites in and the pull bolt type joint effect by joining the first hardware, the second hardware, and the column. In addition, since the reinforcing material is attached to the first hardware, the fixed column is the composite column, and the sandwiched horizontal member is the synthetic horizontal member. Bending moment resistance increases. The axial force of the joint is borne by the column, and the shear force is borne by the tenon of the column, the first hardware and the second hardware, the bolts, coach screws, and horizontal members. It becomes a rigid joint state and the strength increases.

  Further, in the column and horizontal member reinforcing member of the present invention, the reinforcing material is a first wood fixed to the column, a second wood fixed to the horizontal member, the first wood and the second. It is comprised by the 3rd wood arrange | positioned between woods, The said 1st metal fittings are the 5th board, the 6th board, the one end of the said 5th board, and the said 6th between the said 1st-3rd wood. A seventh plate for connecting one end of the plate; an eighth plate for connecting one end of the seventh plate to the first plate; and a ninth plate for connecting the other end of the seventh plate to the second plate. The first plate, the second plate, the seventh plate, the eighth plate, and the ninth plate form a polygonal cavity, and the first wood is the first plate and the fifth plate. The second wood is attached to the second plate and the sixth plate.

  Even if the reinforcing material is exposed, it is the same wood as the pillar and the horizontal member, so that the design is higher than that of the hardware. It also contributes to promoting the use of wood. Since the first hardware is not only the L shape of the first plate and the second plate but also a polygon, the reinforcing strength is increased. Further, the fifth plate and the sixth plate become ribs erected from the corners of the polygon, and the reinforcing strength is further increased.

  Further, in the reinforcing member of the pillar and the horizontal member of the present invention, the third wood is sandwiched between the seventh plate and a third hardware for connecting the first wood and the second wood is provided. It is characterized by.

  Thereby, since the 3rd hardware has connected the 1st wood and the 2nd wood, the tension of the reinforcement member which prevents that the angle of a pillar and a horizontal member spreads is strengthened. Further, since the third wood is sandwiched between the third metal plate and the seventh plate of the first metal plate, the central portion of the third metal plate having bent portions at both ends is prevented from being lifted by tension.

  Further, the reinforcing member of the pillar and the horizontal member according to the present invention includes the fourth wood that covers the third hardware and connects the first wood, the third wood, and the second wood. To do. When the first wood and the second wood are made longer in order to support a position as far as possible from the connecting portion between the pillar and the horizontal member, the wood placed between the first wood and the second wood is multistage (third wood). And the fifth wood), the reinforcing strength can be increased. The fourth wood also serves as a covering material for preventing the exposure and rusting of the third hardware (the fourth hardware when the wood is multi-staged).

The first wood 21 as an additional reinforcing material is attached to the pillar 91 to extend the support point of the pillar 91 (see Y1 → Y2 in FIG. 8), so the section modulus of the pillar 91 fixed by the first wood 21 is increased. This increases the resistance to bending moment of the column due to horizontal force (wind, seismic force). The section modulus of the beam 92 is also increased by the second timber 21, the third timber 23, and the fourth timber 24, and the section coefficient of the pillar 91 is also increased by the second timber 22, the third timber 23, and the fourth timber 24. . Moreover, the same 1st metal fitting 1 is used, without producing a new metal mold | die, The dimension of the 1st wood 21 and the 2nd wood 22 is suitably changed according to the attachment place of a building or the reinforcement member 100. It is possible to easily change the support positions of the columns 91 and the beams 92. For example, an additional reinforcing material can be shortened in a place where only a small amount of reinforcement is required, and a longer first wood 21 or second wood 22 may be used in a place where a large amount of reinforcement is required. Even if the first wood 21 and the second wood 22 are exposed, they are the same wood as the pillars 91 and the beams 92, so that the design is high compared to the exposure of hardware. It also contributes to promoting the use of wood. The material of the fourth wood 24 of the present embodiment is wood because it has a high designability, but is not limited to wood. For example, a paint having a high designability is sprayed on a composite material injection-molded with an FRP material. May be.

  Since the beam 92 is sandwiched between the first hardware 1 and the second hardware 3, the fixing force of the first hardware 1 to the beam 92 is increased, and the beam 92 is prevented from being split. Furthermore, since both the first hardware 1 and the second hardware 3 sandwiching the beam 92 are fixed to the column 91, the tenon of the beam 92 that is pin-joined by capping as a conventional wooden frame construction method is used as the column. The joint portion bending moment resistance is enhanced by the fitting joint effect that bites into 91 and the pull bolt type joint effect by joining the first hardware 1, the second hardware 3 and the column 91. In addition, since the reinforcing material is attached to the first hardware 1, the fixed column 91 is a composite column and the sandwiched beam 92 is a composite beam. Increases resistance. The axial force of the joint is borne by the column 91, and the shearing force is borne by the tenon of the column 91 and the bolts, coach screws, and beams 92 used for the first hardware 1 and the second hardware 3, so The joint becomes a semi-rigid joint and the strength increases. Moreover, it attaches and uses similarly to the corresponding pillar 91 side.

  The reinforcing member 100 of the present embodiment can also be applied to the column 91 in which both the beam 92 and the beam beam 93 are orthogonally joined and pin-joined. FIG. 9 is a perspective view showing this as a modification of the first embodiment. In this modification, the beam 92 and the beam beam 93 have the same height. For this reason, if no measures are taken, the bolts B1 to B4 on the beam 92 side penetrating the pillar 91 and the bolts B1 to B4 on the beam beam 93 side will hit. Therefore, the first hardwood spacer 51 thicker than the diameter of the bolt is inserted between the first hardware 1 on the side beam 93 side and the second wood 22 and the beam beam 93, and the second hardware 3 on the side beam 93 side is inserted. The second hardwood spacer 52, which is thicker than the diameter of the bolt, is inserted between the three plates 31 and the beam beam 93, so that the contact between the bolts can be avoided. In addition, the method of avoiding contact | winning of bolts is not limited to this, For example, you may make the bolt hole H1 into a long hole.

  FIG. 10 is a second modification of the first embodiment showing a case where the beams 92 are on both sides of the column 91. In such a case, the bolts B1 to B4 penetrating the reinforcing members on both sides across the column 91 can be fastened together.

Moreover, the space which attaches the reinforcement member 100 of this embodiment can be attached to the beam 92 and the beam beam 93 up and down, right and left eight directions. FIG. 11 is a perspective view showing this as a third modification of the first embodiment.
