Description

[Detailed Description of the Invention] [Technical field] The present invention is to join outer wall panels that can form a wall body having excellent rigidity, by which the upper and lower floor outer wall panels and the lattice beams can be firmly joined using joining metal fittings. Regarding the structure.

[Background technology]

A building of a dry method in which walls, floors, roofs, etc. are formed using panel bodies is often used. Also, in such a building, the dimensions of each part are determined with a module pitch, which is usually set between 80 and 100 cm, as a reference pitch.

However, conventionally, such a panel body, for example, an outer wall panel forming an outer wall of a house, has a relatively small width, for example, 1
A standard pitch width or a standard pitch width of 2 is often used.

On the other hand, in order to form the outer wall of a house by using such a narrow outer wall panel, conventionally, after forming a skeleton using columns, beams, etc., the outer wall panel is assembled to this skeleton, or The outer wall panel was directly assembled by the joining metal fittings without using the skeleton.

However, the one using the frame structure is inferior in economic efficiency because of increased construction man-hours and member costs.

Further, the above-described joining metal fitting SA has been conventionally used, for example, in the 20th embodiment.
As shown in the figure, wing pieces SC and SD for supporting the outer wall panels PA and PB are laterally provided on the U-shaped base body SB in upper and lower two stages.

On the other hand, with the maintenance of production equipment, roads for transportation, etc.,
In order to improve the construction efficiency and the quality, a large outer wall panel having a width dimension of 3 times or more of the reference pitch is being used.

However, the joint metal SA is made up of narrow width outer wall panels PA, P.
Although the metal fitting SA can be used in B, the metal fitting SA is open on the side and inferior in rigidity, so that the force acting on the joining metal fitting SA becomes excessive in the case of a large and large outer wall panel. Also, the outer wall panel is not continuous between the top and bottom, and the outer wall panel P
A large bending stress acts on A and PB due to the axial force from the roof and the like, which makes it difficult to use for such a large panel.

When using a larger outer wall panel, the height between the outer wall panels may become large in order to increase the size between the ceiling and the floor panel above it for noise prevention and ventilation above the ceiling. . In such a case, the above-mentioned problems are exacerbated.

[Purpose of device]

The present invention is based on the fact that the lattice beams, which are interposed between the outer wall panels above and below the floor, are joined together with the outer wall panels.
The purpose of the present invention is to provide a joint structure for the outer wall panel that allows the outer wall panel and the lattice beam to be firmly connected together, increasing the rigidity and strength of the house and allowing the dimensions of the ceiling and floor to be relatively freely set. I am trying.
