Description

Description: [Industrial field of application] The present invention is applied to an inorganic surface material suitable for use in an industrialized house such as a prefabricated house in which a frame of a building is mainly formed by joining panels. Regarding the joint structure of the panel.

[Prior Art] Generally, in an industrialized house such as a detached prefabricated house,
Labor-saving and simplification of construction work at the site is achieved by standardizing the body, exterior and interior-related members and the like. In recent years, construction methods have been adopted in which the walls and partitions are formed by preliminarily forming the interior groundwork at the factory, etc., so that at the site, the structure is formed by simply abutting and joining these panels. Has been.

By the way, in such a single-family prefabricated house, when a window or an opening serving as a doorway is formed in a wall or partition, a method using a small wall panel as shown in FIG. 7 is generally used. Has been.

FIG. 7 shows an example in which an opening serving as a doorway is formed in a part of the partition, and a small wall panel is attached to the upper part of the opening.

In the figure, reference numeral 1 is a small wall panel, which is attached to an upper end portion between partition panels 2 and 3 which serve as a partition, and an opening portion 4 serving as a doorway is formed in a lower portion of the small wall panel 1. ing. Here, small wall panel 1 and partition panel
Frame body 1 in which core material etc. are assembled into a rectangular contour
On the surface of a, 2a, 3a, the inorganic surface material 1b, 2b, 3 to be the interior base beforehand
An inorganic surface material-attached panel in which b is attached is used.

The small wall panel 1 is arranged so that both end faces thereof are abutted with the end faces of the partition panels 2 and 3, respectively, and is joined almost straight.

Further, the partition panel is provided at the lower end of the small wall panel 1.
Opening uprights (half-divided materials) 5,6 are arranged along the end faces of 2,3, and the small-wall panel 1 is supported by these opening uprights (half-divided materials) 5,6. Has been.

[Problems to be Solved by the Invention] However, such a small wall joint structure using an inorganic surface material-attached panel has the following disadvantages.

That is, since the small wall panel 1 and the partition panels 2 and 3 are joined in a state where their respective end surfaces are butted against each other, it is not possible to obtain sufficient joining resistance between the two.

Therefore, as shown in FIG. 7, it is inevitable to support the lower end surface of the small wall panel 1 by using the opening parts (half members) 5 and 6. However, although it is possible to prevent the small wall panels from slipping vertically downward due to the weight of the small wall panels by using such opening cubics (half-divided members) 5,6, the vertical upward blowing force due to an earthquake, etc. No resistance can be given to.
Therefore, the conventional small wall joint structure is not necessarily strong against the blowing force.

In addition, by using such opening cubics (semi-divided members) 5 and 6, it is necessary to prepare so many kinds of members, which leads to an increase in cost, and these There was also dissatisfaction that complicated the construction work.

The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a joint structure for an inorganic surface material-attached panel that has a high proof strength not only against slippage due to its own weight but also against a vertically upward blowing force.

[Means for Solving the Problems] The present invention has a structure in which side end surfaces of an inorganic face material-applied panel in which an inorganic face material is attached to the surface of a frame body assembled in a rectangular contour are joined together. On the joint side end surface of each inorganic face material-attached panel, opposing notch grooves are provided so as to penetrate in the thickness direction of each panel, and these notch grooves are formed by aligning holes with each other to form the inorganic face material-attached panel. A solution means is that the joining-side end surfaces are joined to each other, and further, a fitting member reaching the cutout groove of each inorganic surface material-attached panel is fitted into the hole formed by the cutout groove.

[Operation] According to the joining structure of the inorganic face material-attached panel of the present invention, the notch grooves provided on the end face on the joining side of each inorganic face material-attached panel are aligned, and the fitting member is fitted into the hole formed thereby. Since it has a fixed structure, the fitting of the fitting member and the hole stabilizes not only the inorganic surface material-attached panel slips off due to its own weight but also the vertical upward blowing force. Is. Therefore, the panel with the inorganic surface material is
It is joined with high joint strength, eliminating the need to use the opening cubic (half-divided material).
