FIG.

In this embodiment, a three-stage wood block 2 is used.
As described above, as shown in FIG. 5,
In the method of assembling the prefabricated wooden wall 1 according to the present embodiment, first, foundation work is performed in substantially the same manner as when a normal wall or the like is constructed on the ground at the construction site. In other words, the ground at the construction site is slightly excavated, concrete material is poured, and the foundation 4 is constructed. At this time, in this embodiment, a square pillar-shaped basic wood member 5 of about 10 cm square is placed on the upper surface of the base 4. As shown in FIG. 6, the basic timber member 5 has 5 cm from each of the upper and lower sides.

When the construction of the foundation 4 and the foundation wood member 5 is completed, the left and right connection holes 2a of the wood block 2 are inserted into the connection support rods 3 projecting upward from the foundation wood member 5 as the first step. The blocks 2 are connected and arranged side by side.
Subsequently, the wooden block 2 is connected to the left and right connecting holes 2a so that the joint position of the first wooden block 2 is centered as the second wooden block from the top of the first wooden block 2. Insert 3 and stack. In the third stage, the wood block 2 to be applied to the uppermost stage as shown in FIG. 3 is similarly inserted as indicated by a dashed line. At this time, the positions of the left and right connecting holes 2a of the wood block 2 inserted into the wood connecting support bar 3 are alternately changed between the odd-numbered steps and the even-numbered steps, as shown in FIG. That is, the wooden blocks 2 of each stage are alternately stacked for each stage and stacked vertically, horizontally, and adjacently.

After the wooden blocks 2 are stacked up to the uppermost step, the nuts 3a are screwed into the screw portions 3a of the connection support rods 3 protruding from the nut chamber 2c on the upper surface of the uppermost wooden block 2. Then, the cover member 2b is fitted from above and fixed with an adhesive or the like. Then, the prefabricated wooden wall 1 is completed by burying the foundation.

The part corresponding to the corner of the wall, as shown in FIG.
A portion where the left and right ends of the wall front face are unevenly combined with a part where the left and right ends of the wall side face unevenly engage with each other so as to be alternately meshed with each other.
Is inserted and assembled.

When a flowerbed is constructed using the assembled wooden wall 1 assembled in this manner, the state shown in FIG. 8 is obtained.

As described above, the assembled wooden wall 1 according to the present embodiment is used.
Are connected to a plurality of square-pillar-shaped wood blocks 2 each having a predetermined length and having a connection hole 2a penetrating from the top surface to the bottom surface, and are inserted through the connection holes 2a of the respective wood blocks 2.

And a fixture comprising a nut 3b.

Therefore, the prefabricated wooden wall 1 of the present embodiment.
Constructs a wall in addition to providing the same effect as a conventional wall, such as preventing earth and sand in the wall from flowing out and protecting objects existing in the wall from the outside. In this case, even those who do not have advanced construction technology can easily assemble, so that the upper surface is horizontal and the wall surface can be beautifully finished by any person, and the construction can be performed at relatively low cost. In addition, since the wall surface is formed of a wooden block 2 which is a natural object, the completed wall surface has a relatively soft impression to a viewer, has a natural atmosphere and is a wall surface excellent in aesthetic appearance. Very suitable for places where aesthetics are required. In addition, since the wood block 2 is formed from wood scraps, the wood can be used effectively, leading to natural protection.

In addition, structures such as flower beds are usually
There are many places where people gather, such as parks, and there are occasions where the human body touches, such as sitting down.In such cases, the walls constructed using conventional bricks or concrete products are hard, especially children Inadvertently hitting the head or the like with the wall due to carelessness, it was easy to get injured. However, in the prefabricated wooden wall 1 of the present embodiment, since it is made of wood, it is relatively soft and injured. There is also an advantage that it is difficult.

The length of the connecting support rod 3 is calculated in advance from the height of the wall to be installed, and is set to an appropriate length such that the screw portion 3a does not project into the nut chamber 2c of the uppermost wooden block 2. It is desirable that the screw portion 3a provided on the connection support rod 3 be provided over the entire connection support rod 3, so that the extra connection support rod 3 is cut off and assembled after assembly. Can also. Further, the diameter and shape of the connection support rod 3 may be any size as long as the wooden block 2 can be supported, and the size of the connection hole 2 a may be changed according to the size of the connection support rod 3.

The wood block 2 is not limited to cut pieces such as small light wood and thinned wood, but can be made by cutting relatively large wood used for ordinary building materials. In order to provide the material at a relatively low cost, it is preferable to effectively use the offcuts. The size is not limited to the above size, but may be any size. However, it is preferable that the aspect ratio of the top surface and the bottom surface is 1: 2. In the surface processing, it is not always necessary to perform baking, chamfer coloring, or spine treatment on the surface, but in particular, by performing chamfer coloring, the wall has an aesthetic appearance that can be used for interior decoration. It is possible to prevent the wall from cracking for a long period of time by the back splitting process. Further, the nut chamber 2c and the lid member 2b of the wood block 2 provided on the uppermost stage may be omitted. In such a case, the screw portion 3a of the connecting support rod 3 is slightly projected from the upper surface, and the nut 3b is removed. What is necessary is just to screw and fix.

The base part in the description of the above-mentioned construction method may be any, and the connecting support rod 3 and the wood block 2
Can be fixed, the base timber member 5 can be omitted, and the connecting support rod 3 can be directly embedded in the base 4 and fixed.
May be omitted and only the connection support bar 3 may be fixed to the basic timber member 5. In such a case, the base wood member 5 may be appropriately changed according to the state of the installation place and the size of the wall.

In addition, the prefabricated wooden wall 1 can be used for decoration in a room. In such a case, the foundation 4 is not necessary as a matter of course. As described above, the wooden blocks 2 may be stacked and fixed with the fixture. Alternatively, only the wood blocks 2 may be connected by the connecting support bar 3 and the fixing tool.

Next, a second embodiment of the present invention will be described. FIG. 9 is a front view showing a main part of the assembled wooden wall according to the second embodiment of the present invention in a connected state. In the figure, the same reference numerals and symbols as those in the first embodiment denote the same or corresponding parts as in the first embodiment.

The structures of the prefabricated wooden wall 1 and the wood block 2 of this embodiment are substantially the same as those of the first embodiment, but differ in the method of connecting the wood blocks 2 and the connection support rod 3.

That is, as shown in FIG. 9, the prefabricated wooden wall 1 of this embodiment is connected by a connecting rod 6 made of a cylindrical wood rod having a diameter of 1 cm to 2 cm and a length of 40 mm to 70 mm. An adhesive is applied to the surface, and approximately half of each is inserted and fixed into the connection holes 2a of the wood blocks 2 adjacent vertically.

Therefore, as in the first embodiment,
It is not necessary to previously process the connection support bar 3 according to the height of the wall and prepare it, and the tightening operation with the nut 3b becomes unnecessary. Further, even when the height and width of the wall are modified during construction, it can be flexibly adapted to the wall.

When connecting the wooden blocks 2 using the connecting rods 6 of the present embodiment, the connecting holes 2a of the wooden blocks 2 do not have to penetrate, but are connected by the connecting support members 3. If possible, holes of any depth are acceptable.
Further, in the first embodiment, the wood block 2 at the top is provided with the lid member 2b and the nut chamber 2c. However, in the present embodiment, a commonly used wood block having the same shape is used. 2 can be constructed. At this time, the uppermost connection hole 2a can be buried with a putty or the like or the connection hole 2a can be formed with a depth of 3 to 5 cm from the bottom surface, so that the upper surface of the wall surface can be beautifully finished.

Further, the wood blocks 2 in which the connecting rods 6 are protruded from the connecting holes 2a up and down by less than half the height of the wood blocks 2 are arranged at even-numbered steps, and odd-numbered steps are provided with connecting holes. Even if the wooden blocks 2 having 2a are arranged and alternately stacked, the assembled wooden wall 1 similar to the second embodiment can be formed in the completed state.
