DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar material for decorating a space between floors and the like, and more particularly to a processed drawn log which is not cracked even after being attached by a craftsman with little knowledge and experience.

[0002]

2. Description of the Related Art A drawing log has been conventionally suitably used as a column material for elegantly decorating a space between floors. This drawn log has a spinning portion 2 formed in advance so as not to cause cracks in the process of drying the raw wood. For example, FIG.
Shipped in condition. When a floor space is completed by using such a drawn log, for example, a carpenter performs an appropriate cutting operation including the backing portion 2 and then fixes the drawn log to a panel frame or the like.

[0003]

However, at the present time, when there is a shortage of craftsmen who are familiar with the characteristics of wood, the left and right sides 1a and 1b of the drawn log sandwiching the backing portion are both fixed to a panel frame or the like. There are many cases that go wrong. And
If the left and right sides 1a, 1b of the drawn log are fixed together, the back pulling portion 2 will not be able to cope with the shrinkage of the wood by expanding in the circumferential direction. Became. The present invention has been made in view of the above problems, and an object of the present invention is to provide a floor column that does not crack afterwards even if attached by a craftsman with little knowledge or experience.

[0004]

In order to achieve the above object, a floor column according to the present invention has a backing portion cut radially outward from a center portion of a column member, and an outer peripheral portion of the column member. It is provided with an excision part cut off including the back pulling part, and an auxiliary member housed in the resection part, wherein the auxiliary member is formed by dividing the column material into right and left with respect to the back pulling part. , And is fixed to only one of the left and right sides. In the present invention, since the column material is movable with respect to the auxiliary member, the occurrence of cracks is prevented by expanding the spinning portion in the circumferential direction in response to drying of the wood. One side in the left-right direction for fixing the auxiliary member is determined by whether the floor pillars are preferably spread left or right.For example, if the floor pillars are installed between the floor and the closet, the side between the floors is fixed. Is preferred. The resection portion according to the present invention includes a first resection portion formed radially outward and a second resection portion formed radially inward continuously from the first resection portion, and the first resection portion includes a first resection portion. It is preferable that the left and right widths are wider than the two cut portions.

[0005] The auxiliary member of the present invention is preferably fixed to the column by a nail member and / or an adhesive, and when a nail member is used, it is immersed in the auxiliary member. The auxiliary member of the present invention is preferably such that its plate thickness is greater than the depth of the second cutout portion, and the left and right width of the auxiliary member is the left and right width of the second cutout portion and the left and right width of the panel frame for fixing the floor column. It is more preferable that the value is set in accordance with If the humidity at the construction site is higher than at the time of shipment, the width of the back pulling portion may be reduced. However, if the width of the second cutout portion and the width of the auxiliary member are matched, the width of the back pulling portion is reduced. It is suppressed by the auxiliary member, so that the left-right width of the first cutout is maintained at a substantially constant value or more. In the present invention, it is preferable that the difference between the left and right widths of the first cutout and the second cutout is set in accordance with the thickness of the plate covering the front and back surfaces of the panel frame. In this case, if the left and right widths of the second cut portion and the auxiliary member are made to match, the gap between the first cut portion formed on the left and right ends of the auxiliary member always exceeds a certain value irrespective of humidity fluctuation. Since it is maintained, there is no possibility that the space for fitting the plate material covering the panel frame is lost. The auxiliary member is preferably formed of wood (such as veneer), and the pillar is preferably a drawn log.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments. FIG. 1 is a plan view showing an embodiment in which a processed drawn log 1 (hereinafter, simply referred to as a log 1) is applied to a floor space 10. As shown in the drawing, the log 1 is fixed to a panel frame 11 with the spinning portion 2 as a back surface. The board members 12a and 12b are fixed to the front and back surfaces of the panel frame 11, respectively. Here, the panel frame 11 is a combination of four pillars, and is composed of left and right vertical frames 11a, 11a and upper and lower horizontal frames 11b, 11b (see FIG. 2). The log material 1 is formed with two cut portions having different left and right widths, and the auxiliary material 3 is accommodated in the narrow cut portion. And back pulling part 2
Log material 1 is divided into left and right based on
And the log right side 1c, the nail 4 is hit only on the log left side 1a to fix the auxiliary material 3 to the log material 1. In this embodiment, the nails 4 are struck at intervals of about 30 cm in the height direction of the log 1, but an adhesive may be used instead of the nails 4 or in addition to the nails 4. In any case, since the log 1 and the auxiliary material 3 are fixed to only one of the left and right sides of the log 1 (in the illustrated example, the log left 1a), the log 1 shrinks in response to drying or the like. However, there is no possibility that the movement of the back pulling portion 2 spreading in the circumferential direction is hindered by the auxiliary material 3. That is, in the illustrated example, since the side between the floors 10 is fixed, the log 1 spreads toward the opposite side (mainly the closet) of the floor between the floors 10.

The log 1 to which the auxiliary member 3 is fixed is a vertical frame 1
By hitting the nail 5 from the side of 1a, the panel frame 11
It is fixed to. Instead of hitting the nail 5, or in addition to hitting the nail 5, the vertical frame 11a and the auxiliary material 3 may be bonded with an adhesive. The vertical frame 11
The nail 4 has its head in the auxiliary member 3 in order to securely fix the a to the auxiliary member 3. The position at which the nail 5 is hit is appropriately set. For example, as shown in FIG. 1, when the nail 5 is hit on the right side 1b of the log, that is, on the opposite side of the nail 4, the tip of the nail 5 has a log. It is desirable not to reach material 1. However, even when the tip of the nail 5 reaches the log 1, if the entry into the log 1 is shallow, the circumferential movement accompanying the contraction / expansion of the log 1 is hardly hindered. When the nail 5 is hit toward the left side 1a of the log, it goes without saying that the tip of the nail 5 may reach the log 1.

Next, the processing procedure of the above-described drawn log 1 will be described. First, as shown in FIG. 3 (a), a spinning portion 2 is formed on a drawn log. The back pulling portion 2 is formed in a rectangular shape including a central portion of the drawn log and having a length exceeding the radius R. The squeezed log provided with the backing portion 2 then proceeds to a drying step, but the backing portion 2 spreads in the circumferential direction due to shrinkage of the wood due to drying, and at the end of the drying process, the substantially V-shaped backing portion 2. (FIG. 3B). afterwards,
An outer peripheral portion of the drawn log including the back pulling portion 2 is cut into a substantially rectangular shape orthogonal to the back pulling portion 2 to form a first cut portion 6 (FIG. 3B). As shown, depth L1, left and right width L2
The left and right width L2 is the same as the left and right width D1 of the vertical frame 11a of the panel frame and the two board members 12a and 12a.
The value is set to a value obtained by adding the thickness b × 2 × D2. Further, the depth L1 is set in consideration of storage of the ends of the board members 12a and 12b.

Next, the second cut portion 7 is formed by cutting the inner side in the radial direction into a substantially rectangular shape perpendicular to the back pulling portion 2 continuously to the first cut portion 6. As shown in FIG. 4A, the cutting is performed over the depth L3 and the left and right width L4, and the left and right width L4 is set to a value that matches the left and right width D1 of the vertical frame 11a of the panel frame. On the other hand, the depth L3 is set to be shallower than D3 corresponding to the thickness D3 of the auxiliary material 3 accommodated in the second cutout portion 7 (L
3 <D3). Finally, as shown in FIG. 4 (b), the auxiliary material 3 having a width D1 and a thickness D3 is housed in the second cutout portion 7, and
If the nail 4 is hit on only one of the log left side 1a and the log right side 1c, the processed drawn log material 1 according to the present embodiment is completed.

[0010] The gist of the present invention is to (a) provide a cutout in advance to facilitate fixing the floor column to another building material, and (b) add another cutout to the cutout. Auxiliary materials used for fixing to building materials must be fixed in advance. (C) However, fixing the auxiliary materials is one that does not hinder the movement of the backing part. Be changed. For example, the size and shape of the resection, the size and shape of the auxiliary material,
It is not necessary to be limited to the embodiment.

[0011]

As described above, according to the present invention,
Even if a craftsman with little knowledge or experience attaches, it is possible to realize a floor column that is less likely to crack later.
