Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar reinforcing device applied to a wooden house or the like, and more particularly, to a pillar frame portion, which reduces a load due to an impact load at the time of an earthquake, and the portion. It relates to a structure that prevents the collapse (separation) of the and protects against vibration such as an earthquake.

[0002]

2. Description of the Related Art A major problem with conventional wooden houses is that they try to suppress the shaking force when an earthquake occurs. For example, as a seismic resistant structure in a wooden house, "joint mortise" is used to reinforce the joints and corners against rolling.
If you fix it just by itself, the joint part is weak and easy to break due to the mortise. Therefore, the plates and fired materials are directly driven into the pillars using iron bolts. In this state, the pillars shake each other due to vibration such as an earthquake, and in the worst case, the house is collapsed. Also, for vertical shaking,
Incorporating braces (slanting materials) in the wall other than studs and braces,
The seismic resistance of the wall is calculated (found by the Foundation and Building Testing Center), and the amount of wall is calculated to strengthen and reinforce the seismic resistance. However, since the braces are also fixed to columns, beams, and girths with bolts and plates, considerable stress is applied, which is a big problem for earthquakes with seismic intensity of 6 or more.

[0003]

The problem of the pillar structure in the conventional wooden house will be more concretely clarified. A concrete example thereof is shown in FIG. 9, and the reinforcing material according to the current Building Standards Law has a tenon structure in which a concave portion 105 and a convex portion 107 that connect the two columns 101 and 103 are formed and fitted. Furthermore,
Holes 109 are formed between the pillars and fixed with straight plate-shaped bolts (reinforcing material) 110 passing through the holes. With this structure, the number of shafts (column structure) is three-axis, and holes are directly passed through the columns, and they are fixed with straight plate bolts. And stresses the pillars themselves. The stress on the pillar means that the pillar itself will crack, and in the worst case,
It leads to the collapse of the house.

Therefore, a load test was performed on the column framing structure provided with the reinforcing material shown in FIG. That is, when a load F of about 1000 kg was applied downward to the tip of the beam column 103, a deformation of about 10 cm was observed at the tip. When this is expressed as a deformation rate, it became 1 / 60π, and it was found that the tenon was broken and an crack was generated for an earthquake with a seismic intensity of 6 or more.

The present invention has been developed in view of the problems found in the above-mentioned conventional column structure, and diffuses an impact load applied to a portion of the column frame structure that occurs during an earthquake to maintain the column frame structure. It is an object of the present invention to provide a column reinforcing device that prevents breakage (separation) of a component part.

[0006]

In order to achieve the above-mentioned object, a pillar reinforcing device according to claim 1 according to the present invention is provided in one column and at least four corners of another column orthogonal to this, and in the longitudinal direction of the column. A fixed plate provided with a channel-shaped fixed piece to be extended and mounting pieces formed to project from both side edges thereof is brought into contact,
A shock absorbing material is attached to the inner wall of the fixing piece of each fixing plate that abuts the four corners of the pillar, and the fixing plates are fixed to the pillar by fastening and fixing between opposing mounting pieces with fastening bolts and nuts. It is characterized in that a reinforcing plate is laid between the fixing plates of one pillar and the fixing pieces of the fixing plates of the other pillars facing the fixing plate.

With the above structure, first, the fixing plate is fastened to the column by fastening the opposing mounting pieces with the fastening bolts and nuts, and is fixed to the column through the shock absorbing material attached to the inner surface of the fixing plate. Indicates that the edge is cut off, and the impact load is absorbed here by the impact absorbing material interposed. Therefore, even if the fixing plates at the four corners are fastened with the fastening bolts and nuts, the fixing plates and the pillars are not locked (fixed) and can be displaced by a small amount. Furthermore, the fixing plates for each pillar are also in a state where the edges are cut off from each other, and since the reinforcing plate is laid across between the fixing plates of both, they are connected to each other, so that the impact load applied to the pillar frame assembly portion is applied to the multiaxial body. It can be dispersed to prevent separation of the framework.

[0008] Further, "twist" and "sledding" which are characteristics of wood
For such "distortion", since the reinforcing device of the present invention does not form a hole in the pillar or penetrate the bolt, the fixing plate is fixed so as to wrap the pillar through the shock absorbing material, The torsion and flexure of the pillars are absorbed to some extent and the pillars are not unduly loaded and the soundness is maintained for a long time.

A second aspect of the present invention for achieving the above object.
The pillar reinforcing device described in claim 1 is the pillar reinforcing device according to claim 1, wherein one or several spacers for finely adjusting a gap between the opposing mounting pieces to a predetermined gap are interposed, and this is a fastening bolt. And the fixing plate is adjustably fixed to the pillar by fastening and fixing with a nut.

As a result, "twist" which is a characteristic of wood
Fine adjustment of the gap between the mounting pieces facing each other by the "strain" such as "sledding" and the error in the outer dimension of the column based on the dryness of the wood by interposing one or several spacers. The fixing plate can be securely fixed to the pillar.

As a result, the fixing plates 5, 7, 9 and 11 are fixed so as to wrap around the columns 1A and 1B via the shock absorbing material 13, and absorb the twisting and bending of the columns, which is a characteristic of wood, to some extent. It does not apply an unreasonable load to the column and elastically absorbs the impact load applied to the column. As the material of the fixing plates 5, 7, 9 and 11, duralumin, ultra-super duralumin (product name: YH7500, made in France), stainless steel, titanium, iron, carbon fiber and the like are used.

The mounting pieces 5B, 7B, 9B and 11B have one or a plurality of fastening bolts 19 (two in the figure).
A hole is formed to pass through. In addition, other mounting pieces (5B and 7B, 7B and 9B, 5B and 11B, 9B and 11) facing each other.
B) also has a hole for passing the fastening bolt 19. Between the opposing mounting pieces 5B, 7B, 9B, 11B,
One or several spacers 15 for fine adjustment to a predetermined gap X are respectively interposed as needed, and spring washers 17, 17 for preventing loosening are interposed on both sides. A fastening bolt 19 is penetrated through each member from one side, and a nut 21 is fastened and fixed. The mounting pieces 5B, 7B, 9
The thickness between the columns 1A and 1B is L1 and L.
The spacers 15 each having a predetermined plate thickness for fine adjustment corresponding to the number 2 are interposed, and four fixing plates 5, 7, 9, 11 are provided.
Is configured to be adjustable and fixed to the pillars 1A and 1B. The material of the spacer 15 is the fixing plate 5,
The same material as 7, 9, 11 is used.

Further, the fixing plates 5, 7, of the first pillar 1A are
9, 11 and the fixing plates 5 of the other pillars 1B facing this
Triangular reinforcing plates 23 are provided on both sides between 7, 9, and 11. As shown in FIGS. 2 and 3, the reinforcing plate 23 is provided with two holes at positions corresponding to the two holes formed in the mounting pieces 5B, 7B, 9B and 11B. And, the reinforcing plate 23, as shown in FIGS.
Two upper and lower reinforcement devices 3 attached to A and a horizontal pillar 1B
The fastening bolt 1 is provided by interposing loosening spring washers 17 on both sides between the mounting pieces 5B and 7B, 9B and 11B facing each other with the one reinforcing device 3 mounted on the left end of the fastening bolt 1.
9 is penetrated from one side, and is fastened and fixed with a nut 21.

Thus, with respect to the vertical pillar 1A,
When the twisting force E that separates and contacts the horizontal pillar 1B in the clockwise or counterclockwise direction acts, the reinforcing plate 23 receives the twisting force E and exerts a reinforcing effect. That is, the structure is such that it is dispersed in a multi-axial body against an impact load and absorbs the impact. The material of the reinforcing plate 23 is also the fixing plates 5, 7,
The same material as the material of 9 and 11 is used.

The embodiment of the pillar reinforcing device 3 of the present invention is based on the above-described structure as a basic structure, and is attached to a main pillar of a wooden house by a predetermined number as required. As shown in FIG. Pillars 1B in horizontal plane and pillars 1A in vertical plane ..
-Can be attached to each joint where and are assembled. That is, when the position of the pillar is at the center, it is attached to all four sides, and when it is at the end, it is attached to one or two sides. Further, as shown in FIGS. 6 and 7, it is also attached to a joint portion extending in three directions and a joint portion extending radially in six directions. Then, the reinforcement devices 3 for these columns mutually function against the impact load due to the front, rear, left, right, and up and down vibrations caused by an earthquake.

The operation will be described based on the above configuration. When installing the pillar reinforcement device 3 of the present invention,
First, as shown in FIG. 1, the fixing plates 5, 7, 9, 11 and the spacer 15 are attached to the four corners of each pillar 1A, 1B, and the attachment pieces 5B, 7B, 9B, 11B are attached to the two fastening bolts 19.
And the nuts 21 with the spring washers 17 interposed on both sides of the spacer 15 for fastening and fixing. And each pillar 1
Mounting pieces 5B, 7B, 9B, 1 on the opposite surface sides of A and 1B
Reinforcing plates 23, 23 are inserted into the space X between 1B, respectively, and two fastening bolts 19 are passed through the holes with spring washers 17 interposed on both sides and fastened and fixed with a nut 21.

Therefore, with respect to "distortion" such as "torsion" and "sledding" which are characteristics of wood, the reinforcing device 3 of the present invention does not form holes in the columns 1A and 1B or penetrate bolts, Since the fixing plates 5, 7, 9 and 11 are fixed so as to wrap the pillar through the shock absorbing material 13, there is no excessive load on the pillar by absorbing the twist and bending of the pillar to some extent.
Soundness is maintained for a long time.

Further, when an earthquake occurs, an impact load acts on the column, and this load is fixed by the fixing plates 5, 7, 9, 11 so as to wrap the column via the impact absorbing material 13, and each fixing plate. Since the spaces are connected by the reinforcing plate 23, first, the impact absorbing material 13 absorbs the energy of the impact load, and further, the reinforcing plate 23 disperses the impact load into the multi-axial body so that the pillar is deformed more than necessary. Do not load. This effect was confirmed by the test method shown in FIG. In this test method, a load test is performed in an embodiment in which a column reinforcing device 3 of the present invention is attached to a joint portion where one end of a horizontal column 1B orthogonal to the vertical column 1A is joined. It was About 1000k at the tip of beam pillar 1B
When a load F of g is applied downward, about 2.5c is applied to the tip.
A very small deformation of m was seen. When this is expressed by the deformation ratio, it becomes 1 / 240π, which is a deformation of 1/4 or less as compared with the conventional reinforcing device shown in FIG. This proves that it has about four times the strength, and it supports the fact that even if the seismic intensity is 6 or more, the tenon of the column will not break and cracks will not occur.

To summarize the above operation, the fixing plates 5, 7,
Reference numerals 9 and 11 are such that opposing mounting pieces are fastened with fastening bolts 19 and nuts 21 and fixed pieces 5A, 7A, 9A, 1
Through the shock absorber 13 attached to the inner surface of 1A, the pillar 1A,
Since it is fixed to 1B, the edge of the column and the fixing plate are cut off, and the impact load is absorbed here by the impact absorbing material 13 interposed. Therefore, the fixing plates 5, 7,
Even if the bolts 9 and 11 are fastened with the fastening bolts 19 and the nuts 21, the fixed plate and the columns 1A and 1B are not locked (fixed) and can be displaced by a small amount. Further, the fixing plates for each pillar are also in a state where the edges are cut off from each other, and the reinforcing plate 23 is laid between the fixing plates of both, so that the impact load applied to the framing portion of the pillar is dispersed in the multiaxial body. , The function of preventing separation of the frame part is exhibited.

The above-described operation is described by using the reinforcing device 3 at one joint as a model. However, in the actual pillar structure of the wooden house, as shown in FIG.
Are columns 1A in the horizontal plane and columns 1B in the vertical plane.
Are attached to the joints with and, and when the position of the pillar is at the center, it is attached to all four sides, and when it is at the end, it is attached to one or two sides. Therefore, the impact load direction A of the impact load applied to the pillar structure of the actual wooden house vibrates in all directions such as horizontal and vertical directions, and the reinforcement devices 3 for these pillars mutually respond to the impact load due to this vibration. Exert function. Of course,
Similar effects are exerted in the frame structure shown in FIGS.

No, the soundness is maintained for a long time.

Further, when an earthquake occurs, an impact load acts on the column. The load is fixed by the fixing plates 5, 7, 9, 11 so as to wrap the column via the impact absorbing material 13, and each of the fixings is performed. Since the plates are connected by the reinforcing plate, the shock absorbing material 13 absorbs the energy of the shock load and disperses the shock load to the multi-axial body without giving unnecessary deformation or load to the column, thereby forming a framework. Effective to prevent separation of parts.

Further, with respect to the "distortion" such as "twist" and "warp" which are the characteristics of wood and the error in the outer dimension of the column based on the dryness of the wood, there is one or more gaps between the opposing mounting pieces. Fine adjustments can be made by interposing several spacers, so even if there are "distortion" such as "twist" or "warp" or an error in external dimensions, the fixing plate can be securely attached to the pillar. There is.

The present invention is not limited to the above embodiment,
