Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a fitting for joining wall panels constituting a peripheral wall of a prefab room flush with each other.

(Prior Art) Conventionally, when constructing the peripheral wall of the prefab room,
A plurality of wall panels are arranged on a base frame as a base body, and are linearly or orthogonally arranged depending on the position to combine them, and are appropriately connected and reinforced by a connecting material or a connecting metal fitting. This wall panel itself has a rectangular frame structure composed of left and right vertical frames and upper and lower horizontal frames, and a surface material such as a tile or PVC steel plate is attached to the surface of such a frame body through a substrate. It is formed. Further, the wall panels are connected by connecting adjacent vertical frames to each other, and as such a connecting fitting, one having a structure shown below has been known. That is, this metal fitting is composed of a first connecting member that is fastened to one of the vertical frames with screws or the like and a second connecting member that can be fitted to the other vertical frame, and the second connecting member is the first connecting member. Even after both members were engaged with both members so that they could slide horizontally, and even after both members were attached to both vertical frames, it was possible to make some fine adjustments such as adjusting the gap between the vertical frames. .

(Problems to be solved by the invention) However, in the conventional case, the wall panel could be adjusted in the direction along the side wall, but did not have the adjustment function in the front-back direction. If they are not connected, there is a problem that a step is formed at the joint.
If this error occurs at the corners, the gap between the wall panels is formed in a strange direction.

(Means for Solving the Problems) In view of the above problems, the present invention relates to, for example, a first connecting member that is horizontally attached to two vertical frames and fixed to one vertical frame, and to the other vertical frame. A second coupling member that fits and slidably engages the first coupling member to form a coupling fitting;
An adjustment bolt is interposed between the first and second coupling members,
The adjustment bolt is configured to be able to change the interval setting between both members.

(Operation) When the adjacent wall panels are not flush with each other at the time of connecting the wall panels, the amount of projecting and retracting the second connecting member can be adjusted by changing the distance between the first and second connecting members with the adjusting bolt. It is possible to eliminate the stepped portion. In the corners,
It is also possible to adjust the direction of the gap.

And a fitting member 12 as a second coupling member that is coupled to the fastening member 11 by a bolt 10 that is screwed into. As shown in FIGS. 4 (A) to 4 (C), the fastening member 11 having the L-shaped cross section has side surface abutting portions 11a that are abutted against the side surfaces of one vertical frame 2, and both vertical frames 2a and 2b. 2 has a rear surface abutting portion 11b that horizontally abuts on the rear surface,
The rear surface abutting portion 11b is provided with a stepped portion 11c at a position corresponding to an intermediate portion between the two vertical frames 2 and 2.
The rear abutment portion 11b on one side is the side abutment portion 1
It is configured so that it can be directly attached to one vertical frame together with 1a,
The other rear surface abutment portion 11b is configured to be engageable with a vertical frame via a fitting member 12 described later. Therefore, the fixing member 1 corresponds to the position of the mounting screw hole 2b of the one vertical frame 2.
1 is provided with a screw hole 11d so that screws can be fixed. On the other hand, the above-mentioned nut 9 is welded to the rear surface abutment portion 11b corresponding to the other vertical frame 2 at a substantially central rear surface side, and the shaft hole 11e and the nut hole 9a provided in the rear surface abutment portion 11b are linearly penetrated. is doing. Two reinforcing ribs 11f and 11f are horizontally provided above and below the nut 9 through a step portion 11c so as to project to the rear surface side and the rear surface abutment portion 1
Flange 11g is formed rearward at the upper and lower ends of 1b.

On the other hand, the fitting member 12 is formed in a U-shaped cross section as shown in FIGS. 5 (A) to 5 (C), and has a shape that allows vertical frame fitting with both side surface portions 12a thereof. The folded-back portion 12b provided at the side is configured to be able to engage with the neck portion 2a on the side surface of the vertical frame 2. Further, a bolting elongated hole 12d is provided along the horizontal direction at substantially the center of the rear surface portion 12c of the fitting member 12, and the bolt 1 shown in FIG.
A round hole 12e having a diameter larger than 0 is provided so as to be connected to each other. The width of the bolt fixing elongated hole 12d is slightly larger than the diameter of the neck portion 10a of the shaft provided in the bolt 10, and the bolt 10 having the neck portion 10a engaged with the bolt fixing elongated hole 12d is horizontally oriented.
