[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is intended to reduce the density of trees in a mountain forest and to support the growth of forest trees. The present invention relates to a panel that uses thinned wood for the purpose of being used for.

[0002]

2. Description of the Related Art Conventionally, it has been considered that thinned wood is a wood that has limited opportunities for effective use because it has problems in thickness and shape. However, recently, effective use of these thinned timbers has been studied. For example, concrete weirs for mountain protection work, which was previously considered unconformable with the surrounding natural environment because the surface of the concrete is bare. An attempt is made to use the artificial structure constructed in nature as much as possible to the surrounding natural environment by covering the surface of the building with a panel made of thinned wood.

Conventionally, based on the above viewpoint,
It has already been attempted to use thinned wood as a covering panel on the surface of concrete weirs or the surface of earth retaining walls, but in the conventional method of using thinned wood of this type, these thinned wood are placed on the back surface. It is assumed that it will be used as a formwork material such as concrete wall surfaces. For this reason, a large number of thinned woods are first arranged in parallel in the horizontal or vertical direction, and the thinned woods are integrally connected in the vertical or horizontal direction by the connecting metal fittings, and the thinning material is applied to the back surface by the connecting metal fittings. It is configured as a formwork panel that also provides adhesion to the concrete being set up.

[0004]

As described above, in the conventional method of coating the surface of a concrete structure with a thinning material, a large number of thinning materials arranged in parallel are vertically and horizontally passed through connecting metal fittings, respectively. While being integrally connected to
Since the formwork panel is constructed so as to obtain the adhesive force with the concrete placed on the back side by the above-mentioned connecting metal fittings, after the concrete dam is completed, the thinning materials forming the panel will be firmly cemented with concrete. Even if it is good to be fixed, there is a problem that if the thinned wood forming the panel is damaged, the thinned wood that has been damaged cannot be easily removed and replaced with new thinned wood. .

For example, when a debris flow occurs in the Tanigawa due to damage from wind and flood, it is conceivable that rocks from the debris flow collide with the surface of the panel and damage the thinned wood material forming the panel surface. As a matter of course, in such a case, it is necessary to immediately remove the thinned wood from the damaged part from the panel surface and attach a new thinned wood to the part.

However, in the conventional panel as described above,
Since each thinned timber is integrally fixed without being detached from each other, when performing repair work as described above, remove only the thinned timber from the damaged part on the panel surface and replace it with a new one. The task of replenishing thinned wood is not easy, and not only all thinned wood that forms the panel surface must be removed, but also the concrete wall surface must be refurbished and replaced with new thinned wood. Large-scale repair work will be required.

[0007]

SUMMARY OF THE INVENTION In order to solve the problems of the panel using the conventional thinned wood as described above, the present invention is to connect the thinned wood with the vertical connection structure and the thinned wood and the concrete surface. By improving the connection structure with, even if the thinned wood forming the panel is damaged, only the thinned wood that has damaged can be easily removed and replaced with new thinned wood. The purpose is to provide such panels.

The panel using the thinning material according to the present invention is
As a concrete means for achieving the above-mentioned object, it is constituted by vertically stacking a pillar having a predetermined length and a panel material using a large number of thinned wood in a cross shape in parallel with the pillar. Is a panel wall structure, the panel material is provided with dovetail grooves at a predetermined interval on the back surface,
Each dovetail groove is fitted to the pillar, and a wedge is driven into both side surfaces of the pillar in the dovetail groove of each panel material, thereby forming an arihozo by the pillar cross section and the wedge in the dovetail groove, and each panel. The material and the pillar are integrally fixed to each other.

[0009]

In the panel according to the present invention, a large number of panel materials made of thinned wood, in which columns are erected at a predetermined interval on the foundation of a concrete weir or an earth retaining wall and dovetail grooves are provided on the back surface, The dovetails on the back side of each of the books are stacked in order from the bottom to the top so that the dovetails fit into the tubular body. At that time, the pillar itself does not have a cross section like an alihozo shape, but when the dovetail groove and the pillar are fitted, the wedges are driven from above into both side surfaces of the pillar in each dovetail groove. Since the cross section of the support pillar is an ali-hozo shape having inclined surfaces by wedges on both side surfaces, it is firmly fixed to the inside of the dovetail groove.

Further, the dovetail groove and the support post are integrally fixed by fitting the above-mentioned wedges after they are fitted to each other, but the support post itself is not in the cross-sectional shape of the arihozo from the beginning, so that each of them is in a fixed state. When mounting the panel material to the column, the dovetail groove can be very easily fitted to the column,
It is possible to easily and efficiently attach the panel material to the column.

The pillar for supporting the panel material is fixed to the concrete cast on the back surface thereof, but the tubular body and the panel material are only connected by fitting of the dovetail groove and the arihozo. Therefore, if it is not fixed by extra nails or bolts, if the thinning material that forms the panel surface is damaged by debris flow, etc., the panel material of the damaged part and the panel material above it It is possible to easily remove a part of the panel material including the damaged panel material from the concrete wall surface by pulling up and along the pillar.

Further, when the dovetail groove of the panel material is removed from the support as described above, the wedge is also easily removed from the support, so that only the support is exposed as it is on the concrete wall surface. By fitting another dovetail groove of another new panel material to the body and driving a new wedge between the dovetail groove and the support, the new panel material can be easily attached.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a panel using a thinning material according to the present invention will be explained with reference to an embodiment shown in the drawings. FIG. 3 and the upper and lower surfaces 2 are flat surfaces, and is made up of a panel material 1 made of a thinned material of a predetermined length, and a support 6 for supporting a back surface 3 of the panel material 1.

On the back surface 3 of the panel material 1, a plurality of dovetail grooves 4 are provided at appropriate intervals in a direction intersecting the length direction of the panel material 1, and each dovetail groove 4 is provided.
, Are respectively fitted to a plurality of the pillars 6 which are erected on a foundation part for constructing a concrete weir or a retaining wall.

As shown in FIG. 2, the column 6 basically has a tubular body 7 communicating with each dovetail groove 4 of the panel material 1 and a plurality of tubular bodies 7 having lengths. And a connecting fitting 8 for connecting in the direction. In addition, the tubular body 7
Is made of box-shaped steel with a rectangular cross section,
Is made of grooved steel having an outer diameter that is inserted into the inside of the tubular body 7, and the connecting metal fitting 8 has a concrete wall projecting in the direction orthogonal to the length direction at the opening side of the grooved steel. It has 5 separator connecting pieces 9.

The connecting metal fitting 8 includes a lower connecting metal fitting 8a fixed on the base 10 by bolts or the like.
An intermediate connecting fitting 8b for connecting the tubular body 7 in the vertical direction,
The upper connecting fitting 8c is attached to the upper end of the uppermost tubular body 7, and the lower connecting fitting 8a has the separator connecting piece 9 protruding from the lower end of the channel steel and the lower surface of the separator connecting piece 9 as well. A bracket 11 for contacting with the rear surface of the base 10 to stably fix the lower connecting fitting 8a on the base 10 is provided. Further, the middle connecting fitting 8b has a shape in which the separator connecting piece 9 is projected from the middle portion of the channel steel, and the upper connecting fitting 8c has a shape such that the separator connecting piece 9 is projected from the upper end of the channel steel. ing.

On the other hand, wedges 12 are driven into both side surfaces of the pillar 6 fitted in the dovetail groove 4. This wedge 12
Is formed by bending a metal plate having a length H that fits in the dovetail groove 4 into an inverted J shape. At one end of the metal plate, a curved bending portion 13 that abuts the side surface of the support column 6 is formed. A locking piece 1 that is provided and engages with the back surface of the support column 6 at the other end in the same direction as the bending direction of the curved bending portion 13.
4 has a bent shape.

Next, the process for forming the panel wall surface by the panel material 1 will be described.
Eventually, it will be provided on the front and back surfaces of the concrete wall 5, but before the concrete wall 5 is constructed, a panel for forming the form of the concrete wall 5 with each panel material 1 in advance. Assemble as a face. When assembling the panel material 1 into a panel surface shape, the lower connecting fitting 8a is arranged and fixed at a predetermined interval on the foundation base 11, and the tubular body 7 is fitted on the lower connecting fitting 8a. After that, the tubular bodies 7 are connected to each other by the intermediate portion connecting fittings 8b, and the columns 6 having a predetermined length are erected.

After the pillars 6 are erected on the foundation base 11, the panel materials 1 provided with the dovetail grooves 4 on the back surface are fitted so that the dovetail grooves 4 on the back surface are fitted to the pillars 6, respectively. hand,
From bottom to top, stack horizontally from top to bottom. At this time, since the pillar 6 has a quadrangular cross section, the pillar 6 can be easily inserted into the dovetail groove 4 of the panel material 1.

In this way, one panel material 1 is arranged so that the dovetail groove 4 and the support pillar 6 are fitted with each other, and then, as shown in FIG. Inverted J-shaped wedges 12 are respectively driven into the gaps 15 between the both side surfaces of the dovetail groove 4 and the both side surfaces of the support column 6. When the wedge 12 is driven, the wedge 12 is brought into contact with the pillar side face 6a above the dovetail groove 4, and the tip portion 13a having a larger thickness due to the curved bending portion 13 is brought into contact with the pillar side face 6a, and the other end is engaged. Apply the stop piece 14 in a sideways shape so as to engage the back surface 6b of the column,
The side edge of the wedge 12 is hit with a hammer and pushed into the dovetail groove 4.

When the pair of left and right wedges 12 are driven into the dovetail groove 4 along the column side surfaces 6a, the post 6 is inserted into the dovetail groove 4.
Since the dovetail-shaped cross section is formed by the wedges 12 on both side surfaces thereof, the pillar 6 and the dovetail groove 4 are firmly fixed to each other. Therefore, thereafter, the panel materials 1 are sequentially stacked along the support columns 6 from the lower side to the upper side by the same procedure to form a panel wall surface having a predetermined area. After constructing a pair of parallel panel wall surfaces so that their back surfaces face each other, concrete is placed between both panel wall surfaces as a formwork to construct a dam.

[0022]

According to the present invention, the respective panel materials are stacked on the prearranged support pillars so that the respective dovetail grooves are fitted to the support pillars. In addition, since the cross section of the pillar is not in the shape of an antler, the panel material can be efficiently assembled to the pillar by a remarkably simple operation of fitting the respective dovetail grooves of the panel material to the pillar.

Further, after assembling one panel material to the support, a wedge is driven into the gap between the support and the dovetail groove, so that the support and the wedge dovetail are formed in the dovetail groove. , At that stage, the panel material will be firmly fixed to the column. Therefore, by repeating the same steps, the panel material can be assembled to the column without using nails or bolts.

Since a wedge is usually driven to tighten the inside of the gap, it requires a force for driving, or the upper end of the wedge that cannot enter the inside of the gap remains and protrudes. Become. On the other hand, the wedge in the present invention is for forming an alihozo corresponding to the inclined side surface of the dovetail groove on both side surfaces of the pillar, so that in the triangular gap between the side surface of the pillar and the inclined side surface of the dovetail groove, It will be driven in a sideways shape so that the side of the wedge will be inserted,
It can be pushed to a position where it is completely hidden inside the dovetail groove without requiring a great amount of force, so that the upper and lower panel materials can be stacked without any gap therebetween.

Further, as shown in the embodiment, when the wedge is made of a metal plate which is bent in an inverted J shape, the tip portion 13a whose thickness is increased by the curved bending portion 13 is formed.
By contacting the pillar side surface 6a and engaging the locking piece 14 at the other end with the pillar back surface 6b, an alihozo inclined surface corresponding to the inclined surface in the dovetail groove can be formed on the pillar side surface 6a. When driving the wedge into the dovetail groove, the locking piece 14 can be pushed downward in a state of being engaged with the back surface 6b of the support column. Therefore, after the wedge is inserted into the dovetail groove, the wedge piece is pushed into the dovetail groove. It can be stably fixed in the dovetail groove while being held integrally with the support column without moving, and a predetermined arizo effect can be exhibited.

The pillar for supporting the panel material is fixed to the concrete cast on the back surface thereof, but the pillar and the panel material are simply connected by the engagement of the dovetail groove and the arihozo, Since it is not fixed by extra nails or bolts, if damage occurs to a part of the thinned wood that forms the panel surface due to debris flow, etc., the panel material of the damaged part and the panel material above it It is possible to easily remove only a part of the panel material including the panel material damaged by pulling it up along the support pillar from the concrete wall surface.

Further, when the panel material is removed from the column as described above, the wedge is also easily removed from the column, so that only the column is projected and exposed on the concrete wall surface, and another new panel material is added to this column. By fitting the dovetail groove of and driving a new wedge between the dovetail groove and the column,
Replacement and repair work for installing new panel material can be easily done.

In addition, as shown in the embodiment, when the column is composed of a combination of a tubular body and a connecting fitting,
The length of the columns can be extended sequentially according to the height at which a predetermined number of panel materials can be stacked at the site, so it is not necessary to stand and fix columns with a large height from the beginning, which simplifies the work. And work time can be shortened. In addition, since the connecting metal fitting that adds the tubular body has a separator connecting piece of concrete wall, if you proceed with the work to assemble the front panel surface and the rear panel surface at the same time, the front panel The surface and the rear panel surface can be connected to each other by the separator connecting piece, and the column can be stably erected.
