The present invention has been made in consideration of the above circumstances, and provides a joint structure of an outer wall panel and a joint structure of a building unit capable of improving the appearance of the joint of the building unit or the outer wall panel. The purpose is to provide.

[0005]

According to a first aspect of the present invention, an outer wall material is installed on a surface of an outer wall panel, and the outer wall material extends to a joint portion of the outer wall panels which are joined to each other. The outer wall panels are joined by fixing a joining material different from the outer wall material in a housed state to the both recesses of the outer wall panel to be joined without forming a recess.

According to a second aspect of the present invention, an outer wall material is installed on the surface of the building unit, and the outer wall material is not extended to form a recess at the joint of the building units that are joined to each other. Then, a joining material different in material from the outer wall material is fixed in the recessed portions of the building unit to be joined in a housed state, and the building units are joined together.

According to a third aspect of the present invention, an outer wall material is installed on the surface of the building unit, and the outer wall material is not extended to form a recess at the joint of the building units that are joined to each other. The bracket is fixed across the both recesses of the building unit to be joined, and a joining material different in material from the outer wall material covers the bracket and is housed in the both recesses, and is attached to the bracket. It has been fitted.

According to a fourth aspect of the present invention, an outer wall material is installed on the surface of the building unit, and the outer wall material is not extended to form a recess at the joint of the building units that are joined to each other. Separate brackets are fixed to the recesses of the building unit to be joined together, and a joining material different in material from the outer wall material covers the brackets and is housed in the recesses. Then, it is fitted to both the brackets.

According to a fifth aspect of the invention, in the invention according to the second aspect, the bracket is formed at a position where the fitting portion for fitting the joining material is accommodated in the joint of the building unit to be joined. It was done.

According to a sixth aspect of the present invention, in the invention according to the first aspect or the second to fifth aspects, the outer wall material and the recess are covered with a continuous coating layer, and the bonding material is used. Is made of non-combustible material.

[0011]

The invention described in claim 1 has the following effects.
Since the joining material is fixed in the recessed portions of both outer wall panels to be joined in a housed state and the both outer wall panels are joined, the joining material is substantially flush with the outer wall material of the joined outer wall panels. The amount of protrusion can be reduced. Therefore, this joining material has a sense of unity with the outer wall surface of the joined outer wall panel, and can improve the appearance of the joined portion of the outer wall panel.

The invention described in claim 2 has the following effects. The joining material was fixed in the recesses of both building units to be joined in a housed state, and both building units were joined, so that the joining material is in a state substantially flush with the outer wall material of the joined building units. The amount of protrusion can be reduced. Therefore, this joining material has a feeling of unity with the outer wall surface of the joined building unit, and can improve the appearance of the joined portion of the building unit.
