BEST MODE FOR CARRYING OUT THE INVENTION The technical idea of the present invention is specifically realized in the embodiments.

The construction method of the present invention in Embodiment 1 is a case where a fence is constructed using wooden blocks. The wooden block keeps alive by repeating expansion and contraction due to changes in temperature in summer and winter, drying and swelling. The expansion and contraction is a slight amount for each wooden block, but there is a fear that it will be a great destructive force that can not be ignored on the many walls and walls of the building. There is a gap between the wooden blocks, and if there are many blocks, rainwater will enter through the gaps. Therefore, it is necessary to waterproof the walls and walls to prevent rainwater from entering.

In the embodiment of the present invention, horizontal grooves are provided on the plane and bottom of a plurality of stacked wooden blocks, vertical grooves are provided on the left and right side surfaces, and a splint is inserted in the grooves to form a slight gap between the wooden blocks. It is made to absorb the expansion and contraction caused by chilling and swelling by using a slight gap between wooden blocks, and the piers sandwiched between each wooden block prevent rainwater from entering from the outside. It can protect the walls of walls and buildings from stretching and rainwater due to seasonal changes.

As a method of stably finishing a wall having a certain area by stacking wooden blocks on a foundation, a pillar bolt can be connected to an anchor bolt driven into concrete and the pillar bolt can be extended through the connecting bolt. I am doing it. A bolt hole is provided in the center of the wooden block, and a pillar bolt is passed through this hole to stack the wooden blocks in several stages. At the top of the pillar bolt, a washer is put on the wooden block and fastened with the fixing screw of the wooden block, but elastic rubber packing or spring may be put under the washer to absorb expansion and contraction. .

The crosspieces of the wooden blocks adjacent to each other in the vertical direction and the vertical grooves of the wooden blocks adjacent to each other on the left and right are passed through the crosspieces so that the surfaces of the blocks coincide with each other. Under the same conditions, put a wooden bar with a smaller expansion coefficient than the material of each wooden block into the groove, and finally put a washer on the prop bolt through the elastic rubber packing or spring to make the wooden block. If the block fixing screw is fastened, the absorption effect of the vertical expansion and contraction is effective, and in the wet season, the wooden block expands to bring the pier into close contact, which enhances the waterproof effect.

The width of the pier inserted between the wooden blocks is
It has a width more than twice the depth of the groove to enhance the waterproof effect. If the width of the pier is more than twice the depth of the groove, the gap between the upper and lower wooden blocks and the gap between the left and right wooden blocks can be formed, so that the pier will close and expand effectively in the wet season to provide effective waterproofing. That is, when the wooden block expands in the wet summer, the pier is sandwiched between the blocks, so that rainwater can be prevented from entering.

As the material of the wooden block, cedar wood having a large expansion coefficient may be used, and in comparison with this, the wood material having a smaller expansion coefficient, such as cypress, is a preferable material. The expansion coefficient of the material of the wooden block is different from that of the material of the wooden block, and a slight expansion of the wooden block forms an air layer in the gap between the wooden blocks between the wooden blocks to improve heat retention. It is possible to prevent the distortion by absorbing the expansion and contraction by the gap.

At the position where the fence bends from a straight line, the corners are triangular,
You can rectify the bend by standing up square, hexagonal, etc. timbers as pillars and building the corners by applying the side of the wooden block to the side of the timber.

The construction method of the present invention in Embodiment 2 is a case where a house is constructed using a wooden block. Anchor bolts are driven into the concrete foundation at regular intervals, post bolts are connected to this, and post bolts are connected via connecting bolts for extension. Through the post bolts in the bolt holes of the wooden block 1a, wooden blocks are piled up. The tip of the pillar bolt is fixed to the beam to support the wall.

If the wooden block 1a has a horizontal groove on the plane and the bottom surface in the longitudinal direction and vertical grooves on the left and right side surfaces, and if the wall of the wooden block 1a is constructed with the pillar bolts, the horizontal groove and the left and right of the wooden block above and below the wall are formed. The vertical grooves of the wooden blocks adjacent to each other are the same, and the width of the pier that is a little wider than the groove width between each wooden block can prevent flooding, and also absorb the expansion and contraction in the gap between the blocks to provide a stable wall surface. There is an effect composed of.

The wooden block 1a according to the third embodiment has horizontal grooves on its plane and bottom surface and vertical grooves on its left and right side surfaces.

The wooden block 1b of the fourth embodiment is a case where the structure of the wooden block 1a is characterized by having a vertical groove on the front surface or the back surface. The sides of the wooden blocks can be connected at right angles to this vertical groove, and a partition can be provided on the wooden block wall or the wall of the building.

Example 1 A case where a fence is constructed using wooden blocks by the construction method of the present invention. The wooden block 1a has horizontal grooves on the plane 2 and the bottom surface 3 in the longitudinal direction, vertical grooves 4 on the left and right side surfaces, and the pillar bolts 10 are connected to the anchor bolts 7 driven into the concrete foundation 6 for connection. The prop bolt is extended through the bolt 9, and the prop bolt is passed through the bolt hole 17 of the wooden block 1a, and the wooden blocks are stacked in several stages to construct a fence.

The horizontal groove of the wooden blocks adjacent to each other vertically and the vertical groove of the wooden blocks adjacent to each other on the left and right are made to coincide with each other, and the pier having the expansion coefficient of the material smaller than that of the material of each wooden block is used. Then, the washer is inserted into the post bolt and the fixing screw of the wooden block is fastened, and the upper cover 11 of the fence is fixed on this with the cover fixing screw nail to make the wooden block fence.

The width of the crosspiece 10 to be inserted into the horizontal grooves 2 and 3 and the vertical groove 4 between the wooden blocks is more than twice the depth of the groove. If the width of the pier is more than double the depth of the groove, the gap between the upper and lower wooden blocks and the gap between the left and right wooden blocks can be formed slightly. Even if the wooden block expands, the gap can absorb the expansion and contraction. If cedar wood having a large expansion coefficient is used as the material of the wooden block, a wood material having a smaller expansion coefficient than that, for example, cypress, etc., is used to form the pier. It is possible to prevent the warp by using the material of the wooden board having the expansion coefficient smaller than that of the material of the wooden block to absorb the slight expansion and contraction of the wooden block and absorb the entire expansion in the gap between the wooden blocks.

At the position where the fence bends from a straight line, the corners are triangular,
You can rectify the bend by standing a pentagonal or hexagonal timber as a pillar and building a corner by applying the side of the wooden block to the side of the timber.

[Embodiment 2] A case where a house is constructed using a wooden block by the construction method of the present invention. The pillar bolts 8 are connected to the anchor bolts 7 which are driven into the concrete foundation 6 at regular intervals, and the pillar bolts 8 are further connected via the connecting bolts 9 so that the pillar bolts are extended to the bolt holes 17 of the wooden block 1a. Is a pillar bolt 8 and a crosspiece is passed through the horizontal groove and the vertical groove, and a wooden block is piled up on it.
It constitutes a wall supported by a pillar bolt, and the tip of the pillar bolt is fixed to the beam.

When the wall of the wooden block 1a is constructed by the pillar bolts 8, the horizontal grooves 2 and 3 of the upper and lower wooden blocks of the wall and the vertical grooves 4 of the adjacent wooden blocks on the left and right are aligned with each other. The pier 10 is inserted in the groove between them. The width of the pier put in it is slightly larger than the groove width to form a small gap between the upper and lower wooden blocks and a gap between the left and right wooden blocks, so this pier can prevent water from entering. The gap between them absorbs the expansion and contraction, forming a stable wall surface.

[0032]

The effects of the present invention are as follows.
With the configuration of the invention described in (1), the following effects are exhibited.

In the expansion and contraction construction method and the structure of the wooden block shown in the embodiment of the present invention, since the gap between the wooden blocks is formed by the interposition of the wooden blocks between the wooden blocks, the wooden blocks are swelled due to temperature difference or swelling in summer and winter. It is possible to construct a stable wooden block wall surface that absorbs the expansion and contraction that occurs without difficulty and does not cause distortion.

Under the same conditions, by inserting a pier with an expansion coefficient different from that of the material of the wooden block between the wooden blocks, the pier can be closed in the wet season of summer to enhance waterproofness. The length of the bolts can be extended, and it is a method that can be used even if the wooden block wall or the wall of the house is raised. The pier is hardly noticeable from the outside, and it is possible to create a waterproof wall surface without losing the original wood texture of the wooden material of the wooden block.

Since a wooden block wall is constructed by arranging a prism on the corner and applying a side surface of the wooden block to the prism, a curved wall can be elegantly made.

In the construction method of the present invention, an air layer is formed between the wooden blocks having a large expansion coefficient by combining the materials having a smaller expansion coefficient than the materials of the wooden blocks, between the wooden blocks having a large expansion coefficient. It Therefore, the structure of the wooden block of the present invention can prevent the wall surface from being distorted and enhance the waterproof property of the wall surface in the wet summer, and the heat retention is good due to the air layer contained in the wall surface in the dry season of winter. Is.
