Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing a pillar, which is a main structural member of a house or other wooden building, at a predetermined position.

[0002]

2. Description of the Related Art A relatively small-scale building is often made of wood. Especially for residential applications, wooden houses are in great demand because they are comfortable to live in. As is well known, in traditional wooden houses, timber is also used for the pillars that mainly carry the vertical load. Even in a one-story house, the pillars that must support roofs including roof tiles, etc. are made of materials with sufficient strength against the load from above, and the foundation foundation at the bottom and the beams at the top (beams: horizontal bridges) Fixed to.

[0003] By the way, even in a column where a downward load is exclusively applied everyday, an upward load, that is, a force for pulling out the column is applied in the event of a large earthquake. In addition to the pull-out load due to direct vertical movement, even if it shakes in the horizontal direction, a large pull-out load is concentrated on the pillar on one side due to the inertial action of the house. Of course, in order to deal with such a situation, the pullout load is widely reinforced, and in the case of three or more stories, the stipulated reinforcement is obligatory. That is, the lower horizontal wooden base and the lower part of the pillar are firmly tied to the concrete foundation or the foundation by using the hole-down hardware and the corresponding hole-down anchor bolt or washer bolt.

In FIG. 3 (a), the hole down hardware (21) is combined with the hole down exclusive anchor bolt (22) to form the pillar (3).
Fig. 3 is a perspective view showing a state where the base is fixed to the base (2).
(b) is a perspective view of a hole down hardware (21 ') having a different shape, which is combined with the hole down anchor bolt (22). Anchor bolts (22) for hole downs for general houses are often used with an outer diameter of 16 mm, and the tip is a male thread of M16.

As shown in FIG. 3 (a), such anchor bolts (22) dedicated to hole down are planted at predetermined positions when the foundation (1) is made. Then, the hole down anchor bolts (22) and anchor bolts (7) protruding from the concrete foundation (1) from the lower surface side of the wooden foundation (2) are inserted so that the foundation (1) is The base (2) and foundation (1) are firmly fixed by placing them on the upper surface of the anchor bolt (7), applying a washer to the tip screw part of the anchor bolt (7) and tightening with a hexagon nut (8).

After assembling the pillar (3), the hole-down hardware (21) is inserted into the pillar (3) through the vertical through hole under the pillar (3), and the pillar (3) is firmly fixed with a hexagon bolt or a lag screw (24). After mounting, screw in the hexagon nut (23) at the tip of the hole down anchor bolt (22) to firmly fix them. As a result, the pillar (3) is firmly fixed directly to the foundation (1) by sandwiching the base (2) and has sufficient strength against pull-out stress. Also in FIG. 3 (b), only the hole-down hardware (21 ') having a different shape is used, and the anchor bolt (7) is used for the base (2) in the same process as described above.
The foundation (1), but also the anchor bolts (2
The pillar (3) and foundation (1) are firmly fixed by 2). As a result, the columns (3), the base (2), and the respective parts of the foundation (1) are firmly fixed, and the column lower end has sufficient strength against pull-out stress.

Then, as shown in FIG. 4 (a), a horizontal member (4:
Beams, etc. are also combined and fixed, and braces (5) and studs (6) for wall reinforcement are attached to complete the wooden frame (framework). A reinforcing plate (25) is attached to the pillar portion as needed for attachment reinforcement. The hole-down hardware (21 ') is properly attached to the pillar, which is a key point. Another example of the arrangement of hole-down hardware, pillars, braces, etc. is shown in Fig. 4 (b). In this example, columns (3) and beams (4)
The reinforcing plate (25) and the reinforcing triangular plate (26) are also used for reinforcing the fixing force of the.

Besides, the hole-down hardware is not fixed directly to the foundation but fixed to the base with washer bolts. Figure 5 (a) shows the hole-down hardware (21) with the washer bolt (2
FIG. 6 is a perspective view showing a state of being fixed to the base (2) by 6).
Fig. 5 (b) shows an example of a bolt with a washer dedicated to the base. For general houses, iron bolts with an outer diameter of 16 mm are often used, and one end is formed into a square washer with a side of 80 mm and a washer with a thickness of 9 mm, and the other end is threaded with an M16 male screw. The washer bolts (26) are used to bind the base (2).

That is, the bottom of the base of the column (3) to which the hole-down hardware (21) is attached is previously dug into the ground, and the bolt with the washer is inserted into the through hole from the lower surface, and the wooden base is inserted.
Place (2) on top of concrete foundation (1)
Anchor bolt protruding from (1) and inserting the base (2)
Place the washer on the tip screw part of (7) and tie it with a hexagon nut (8) to firmly fix the base (2) and the foundation (1). Then, after combining the pillars (3), firmly attach the hole down hardware (21) to the pillar (3) with hexagon bolts (24), etc.
Fasten the end of the bolt with washer (26) inserted in the lower part of the above with a hexagon nut (8) to fix them firmly. As a result, the pillar, the base, and each part of the foundation are firmly fixed and have sufficient strength against pulling stress. Of course, the hole-down hardware with different shapes (21
′) Can be used as well. Then, the beams and the like are combined and fixed to complete a predetermined wooden frame (framework). As described above, even when the hole-down hardware and the washer bolt are used, the columns, the base, and each part of the foundation are fixed with sufficient strength in the same manner as described above, and have sufficient strength against pull-out stress.

[0010]

By the way, in the conventional method for reinforcing the column fixing force using the above hole down hardware, many screws must be fixed, which is complicated and requires a lot of man-hours. In addition, if the beam is not significantly reinforced against pull-out stress, or if it is reinforced from the side with a reinforcing plate such as a triangular plate, a sufficient pull-out stress is applied due to an earthquake, etc., and sufficient strength is obtained. However, on the other hand, it was necessary to fix screws at many points, and the number of man-hours increased and the addition of members led to a large increase in the work cost that cannot be ignored.

The present invention has been made in view of the various circumstances related to the mounting and reinforcement of a column as described above, and a method of reinforcing the fixing force of a column having a higher reinforcement effect against the pulling stress at a lower cost than the conventional one. The purpose is to propose a new.

In this way, it is extremely easy to secure the columns firmly between the upper and lower bridges, while having sufficient strength against the strong stress of pulling out the columns and the stress of pulling out the rod-shaped wooden beam (4) upwards. can get.

[0017]

The method of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 (a) is a side view showing a pillar portion for explaining a frame portion of a wooden structure to which a wooden pillar is fixed by applying the present invention, and FIG. 1 (b) is an enlarged view for explaining a superstructure thereof. FIG. 2 is a perspective view, and FIG. 2 is an enlarged perspective view for explaining the lower structure of the same.

In the portion shown in FIG. 1 (a), a conventional concrete foundation (1) is first constructed, and various wooden members including columns (3) are fixed on the foundation (1). The foundation (1) was constructed in the same manner as the conventional one by anchoring anchor bolts (7) for fixing the base (2). Then, a pair of locking connecting members (11H, 11L) and a biasing connecting member (12) are used as reinforcing members (10) for fixing the pillar (3) together with other members on the foundation (1). . The locking connection members (11H, 11L) used in the examples have a structure similar to that of an existing brace used as a construction material, for example, as a bracing for reinforcing wall surfaces.

The reinforcing member (10) connects the pair of rod-shaped locking connecting members (11H, 11L) to each other in the middle, and adjusts the interval between both locking connecting members by a screw action to reinforce. Material (1
0) As a whole, it is composed of a biasing connecting member (12) for giving a tension. The locking connection members (11H, 11L) in Fig. 1 are
One end is formed in a washer shape as a locking end portion (11a, 11a) that is fixedly engaged with the base (2) or the rod-shaped beam member (horizontal member; 4). The other end of the pair of locking connection members (11H, 11L) has a screw shape in which male screws are screwed as the coupling end portions (11b, 11b '), but these male screws are in opposite directions. It is threaded (one is a reverse thread).

The urging connecting member (12) for joining the two locking connecting members (11H, 11L) in the middle is, so to speak, an intermediate connecting screw,
Female screws (12a, 12a ') in opposite directions are screwed on the same shaft at both ends of an integral metal member such as iron. In the example shown in the figure, through holes are used in the middle part, which is more commonly used than before, and female screws (for example, 12a 'are reverse screws) in opposite directions are screwed at opposite positions on the same axis at both ends of the frame part. It has the same shape as the one done.

A method of reinforcing the fixing force of the wooden column using the reinforcing member (10) will be described. First, the concrete foundation (1) is applied exactly as in the past. At a predetermined position of the square bar-shaped wooden base (2) that is placed and fixed on this foundation, that is, in the vicinity of the site where the pillar is to be fixed (for example, 50 to 10
A through hole (2h) slightly larger than the diameter of the rod-shaped part of the locking connection member (11H, 11L) described above is preliminarily opened (in the mounted posture) in the vertical direction. Further, a similar through hole (4h) is previously formed in the horizontal member (4) at a corresponding position right above the through hole (2h) during assembly.

Then, when the wooden base (2) is placed and fixed on the foundation, one of the locking connection members (11H, 11L), for example, the one having a right-hand thread at the tip is used as the locking end. Insert the base (2a) into the through hole (2h) so that the part (11a) faces downward.
Align the anchor bolts (7) and place them on top of the foundation (1). Then, the hexagonal bolt (8) is screwed into the threaded portion of the tip of the anchor bolt protruding from the upper surface of the base (2) through a washer, and the base (2) is firmly fixed to the foundation (1). Next, after assembling the wooden pillars (3) in place and standing them up, the upper end of each pillar (3) and the wooden beam member, which is usually a square bar shape.
Attach (4: Horizontal material).

After that, one left end of the locking connecting member left-threaded (11H) is inserted into the through hole (4h) of the rod-shaped wooden beam (4) from the connecting end of the end. Locking end (11
a) is brought into contact with the upper surface (abutment surface: 4b) of the rod-shaped wooden beam (4) to hang it down. Then, both locking connection members (11
H, 11L) The connecting end parts (11b, 11b ') at the tip are screwed together with the urging connecting member (12) as a tension applying member and the screw part (12a, 12a'), and urging and connecting as a connecting screw. By rotating the member (12) in a predetermined direction, both locking connection members (11H, 11L) approach each other according to the rotation, and the respective locking end portions (11a) are moved to the base (2).
The lower surface (2b) and the upper surface (4b) of the rod-shaped wooden beam (4) are in close contact with each other.

Further, by rotating the biasing connecting member (12) and tightening the screw to an appropriate position, the metal reinforcing member in which the biasing connecting member (12) and both locking connecting members (11H, 11L) are integrated The member (10) is firmly fixed in a state in which the base (2) and the beam (4) are pulled together with the pillar (3) interposed therebetween. Pillar in this way
The fixing of (3) and the reinforcement of the fixing force are completed.

In the above-mentioned fixed state, the upper and lower engaging connecting members (11H, 11L) and the central urging connecting member (12) are integrated with respect to the stress in the direction of pulling out the column (3). The metal reinforcing member (10) is directly attached to the base (2) and the bar-shaped wooden beam.
(4) is firmly fixed, and the base (2) is an anchor bolt.
It is firmly fixed to the concrete foundation (1) by (7). Therefore, the rod-shaped wooden beam (4) and the base (2) do not separate due to the drawing stress, and naturally the column (3) sandwiched between the two does not loosen.

As described above, the fixed state of each part of the embodiment is extremely strong by the reinforcement, and the column (3) is securely fixed.
It should be noted that the method of the present invention, of course, firmly fixes the pillar at a predetermined position, but from a different point of view, it includes the base, the pillar standing on this, and the beam member (horizontal member) that is combined with the upper end of the pillar. This means that a series of members that have been fixed are firmly fixed. In the embodiment, since the metal member having the same diameter and the same material as the metal bolt specified for fixing the hole-down hardware is used, the same pull-out strength as that when the hole-down hardware is used is obtained. The reinforcement effect is that the column is fixed to the base in the same way as when using the hole-down hardware, and the effect further extends to the beam part and exceeds the hole-down hardware.
It is a much better reinforcing method.

Further, at the same time, the construction is extremely simple compared with the case of using the hole-down hardware, the material cost is not increased, and it can be considered to be the same in terms of cost considering that a separate upper reinforcing member is unnecessary. In addition, if the use of hole-down hardware is obligatory by laws and regulations, it may be used in combination with fixing by hole-down hardware, which will reinforce the fixing of the beam portion and further strengthen the column fixing.
The effect of the method of the present invention is not limited to the reinforcement of the fixing force of the column, and the compressive force of the column and the tensile biasing force of the metallic reinforcing member are in a balanced state, and as a result of this, the foundation, the column and the beam member are used. It also has the effect of preventing the deformation of the frame structure, and also has the effect of increasing the strength of the entire frame structure and thus of the entire building.

As described above, according to the method for reinforcing the wooden column fixing force of the present invention, the rod-shaped wooden base (2) fixed on the concrete foundation (1) and the wooden column on the rod-shaped wooden base (2).

L) The rod-shaped wooden base (2) is urged so that they come close to each other.
The wooden columns (2) are fixedly reinforced between the rod and the wooden beam (4).

According to these methods, the engagement between the upper and lower bases of the pillars and the horizontal members is a very simple process, and the urging can be done very simply by rotating the connecting portion with a screw and with a low man-hour. Depending on the conditions, a part or all of the braces of the existing commercially available products can be diverted to the reinforcing member, and in this case, it is more advantageous in terms of cost.

The essential point of the technical idea of the present invention is that the horizontal members extending vertically correspond to the pillars that are sandwiched between them and fixed and urged, and the reinforcing member is composed of three parts. Therefore, the same method can be applied not only to the pillars on the first floor of a wooden building, but also to the pillars on the second and third floors, increasing the strength against pull-out stress of corresponding parts such as pillars and beams. it can.

That is, a pair of metal long locking connection members are vertically connected to corresponding positions of the upper and lower rod-shaped wooden beam members that face each other and sandwich the wooden column and extend correspondingly. Part, and the remaining coupling ends of both locking connection members are fixed by the urging connection member (12) and urged toward each other, thereby fixing the wooden column between the rod-shaped wooden beam members. It is also beneficial to do so.

[0034]

As described above, in each method of the present invention, the reinforcing member is composed of three parts, and the horizontal members extending vertically are fixed and urged together with the pillars sandwiched therebetween. By each of the above-mentioned processes, it is possible to obtain a notable strength against the pull-out stress applied to the building including not only the pillar but also the upper beam. At the same time, it also has an effect of preventing deformation of the frame structure composed of the base, the pillars, and the beam members. In addition, the work itself is very easy to lock with the bases and the horizontal members above and below the pillars, and the urging is simple only by screwing the connecting part with a rotating screw, the material is cheap, and the necessary cost is extremely low. .
