  However, the above-mentioned conventional wall structure is required to further improve the ability to discharge water that has entered between the structure and the wall material to the outside.

  An object of the present invention is to provide a wall structure and a method for constructing a wall, which can further improve the ability to discharge water entering between a structure and a wall material to the outside.

The wall structure according to the first aspect of the present invention includes a structure,
A drainer attached to the structure,
A wall member having a first gap with the upper surface of the draining portion, and a wall member attached to the structure with a second gap between the wall and the structure;
A wall member disposed on the upper surface of the drainer, and a wall structure,
The eye plate member,
A fixing piece attached to the structure,
A joint that is arranged on the upper surface of the drainer, extends along the wall material, and at least partially enters the first gap from the structure side;
The joint has a first joint and a second joint separated from each other in a direction in which the draining portion extends along the wall material,
The distance between the first joint portion and the second joint portion is defined by a first opening located in the first gap and opening to the front surface side of the wall material, A second opening that opens between the back surface and the structure,
A first end of the first joint facing the second joint and a second end of the second joint facing the first joint are sealed, and the first opening is closed. And a side wall surface for communicating the second opening with the second opening.

  In the wall structure of the first aspect, at least a part of the joint portion enters the first gap between the lower end of the wall material and the upper surface of the draining portion. Thereby, the water that has entered between the structure and the wall member is likely to stay on the joint extending from the structure side to the lower end of the wall member, not on the upper surface of the drainage portion. When the amount of water staying on the joint increases, the water flows to the second opening via the first joint and the second joint of the joint. Then, the water is discharged to the outside from the first opening communicating with the second opening by the side wall surfaces formed at the first end and the second end. For this reason, it is difficult for the water to collect on the upper surface of the drainage portion, and it is difficult for the water to flow to the side of the drainage portion through the upper surface of the drainage portion. The water can be prevented from flowing to. As a result, the water hardly stays between the structure and the wall material.

  Therefore, in the wall structure according to the first aspect of the present invention, it is possible to further improve the ability to discharge water that has entered between the structure and the wall material to the outside.

  As a second aspect of the present invention, it is desirable that the fixing piece has a flat plate shape and extends upward from the draining portion.

  In this case, a flat fixing piece covers the structure above the draining portion. Thus, the water that penetrates between the structure and the wall material and drips along the structure is suitably guided by the fixing piece onto the first joint and the second joint. As a result, the water hardly stays between the structure and the wall material.

  As a third aspect of the present invention, it is preferable that the first joint and the second joint are formed integrally with the fixing piece.

  In this case, since there is no need to align the first joint and the second joint, the construction work can be simplified.

  As a fourth aspect of the present invention, in the direction in which the draining portion extends along the wall material, one end of the joint portion is located at a position coinciding with one end of the draining portion, or one end of the draining portion. It is desirable to be in a position that exceeds.

  In this case, it is possible to more reliably suppress the water from flowing to the lower surface side of the draining portion by the joint portion.

  As a fifth aspect of the present invention, it is preferable that the first end of the first joint and the second end of the second joint are sealed by a sealing member.

  In this case, the operation of sealing the first end portion and the second end portion with the sealing member at the time of on-site construction can be easily performed. As a result, the water stopping performance is improved, and the construction work can be simplified.

  As a sixth aspect of the present invention, it is desirable that a slit is formed at the lower end of the wall material. And it is desirable that the wall member has a locking piece that can be inserted into the slit and is attached to the structure via a lower end support member that can be fixed to the fixing piece.

  In this case, the first joint portion and the second joint portion do not directly support the lower end of the wall material. For this reason, the deformation of the first joint portion and the second joint portion can be suppressed, and the deformation of the first opening and the second opening can be suppressed. As a result, it is possible to further improve the ability to discharge water that has entered between the structure and the wall material to the outside.

  As a seventh aspect of the present invention, it is preferable that a joining portion extending in the vertical direction is formed between two wall materials adjacent to each other in the direction in which the draining portion extends along the wall material. The first opening is desirably located below the lower end of the joint.

  In this case, water dripping along the joint of the wall material can be smoothly guided to the first opening, and the water can be smoothly discharged to the outside from the first opening. As a result, the water hardly stays between the structure and the wall material.

  According to an eighth aspect of the present invention, there is provided a drainage device disposed between a first end of a first joint and a second end of a second joint in a first gap and communicating with a first opening. Further, it is desirable to provide.

  In this case, the appearance of the first opening can be improved by the drainage device. Further, the water passing through the first opening can be smoothly discharged to the outside, and the backflow of the water due to the blowing of wind and rain can be prevented.

The construction method of a wall according to a ninth aspect of the present invention includes a structure,
