Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for joining tile wall panels in a unit construction method and a joining tool used therein.

[Conventional technology]

Recently, bathrooms and other units have been made into units in order to streamline construction at construction sites and shorten the construction period.

Bathroom unitization involves producing components such as ceilings, side walls, floors, etc. in a factory, then transporting them as is to a construction site and assembling them at a predetermined location. The present invention relates in particular to the joining of tile wall panels constituting side walls.

Figures 5 and 6 are diagrams showing the structure of a unitized tile wall panel, in which a frame is formed by welding a vertical frame 1 and a horizontal frame 2 of hollow square steel pipes, and a base material such as an asbestos cement board 3 is used. is fixed, and a surface material 4 such as a semi-porcelain tile book is attached to the surface using an adhesive 5 such as Niboxy resin. The tile walls and base panels formed in this way are set up adjacently and connected to each other using gel through coaxial horizontal communication holes 6 previously drilled in both adjacent vertical frames 1. to form a continuous side wall.

[Problem that the invention seeks to solve]

It is not easy to assemble such a tile wall motherboard immediately before the side wall of an already completed building frame. In this case, the tile wall panel is erected with a slight gap between the vertical frame 1 and the side wall of the frame, and with the vertical frame 1 facing the side wall of the frame.

As mentioned above, the first method for joining tile wall panels is to perform gel joining on the back side of the tile wall panels with a space large enough for a person to work.In other words, after assembling the tile wall panels well in front of the side walls of the structure, the predetermined However, this is not only time-consuming, but may even be impossible depending on the space available at the site.

The second method shown in FIG. 7 is an improvement on the above method, in which one working hole 7 is previously drilled in the base material 3 of both tile wall panels near the communication hole 6 of the vertical frame 1 to be joined. . Therefore, some of the tiling at the position of the working hole 7 is omitted. Insert both hands holding the gelt 8 and nut 9 into the working hole 7, fit into the communicating hole 6 on the back side of the tile wall/9 panel, and connect them. After joining, the working hole 7 is closed with the tile 4. However, in this case, two working holes 7 are required for each joint location, so a large number of working holes 7 are required, and there is a drawback that it takes a lot of time to close the holes.

FIGS. 8 and 9 show a third method in which one working hole 7 is provided for one joining location, in which the 8th
The figure shows a plane connection similar to that in FIG. 7, and FIG. 9 shows a corner connection.

In Fig. 8, a case nut 10 (a nut built into a box-shaped case to prevent the nut from turning inside the box) is shown.
is fixed to one vertical frame 1 by means such as welding. In FIG. 9, an angle member 11 to which a case nut 10 is welded is placed, for example, by welding to the vertical frame 1 of the tile wall panel on the right, and the vertical frame 1 of the tile wall panel on the left is attached to the case nut 10.
are combined with gelt 8. This third method is undesirable because it requires a case nut 10 and in particular uses welding, which is the most skilled and time-consuming process.

The present invention aims at providing a method and a joining tool which eliminates the drawbacks of the above-mentioned methods and in particular improves the third method.

[Means for solving problems]

A first aspect of the present invention that solves the above-mentioned problems is to install tile wall panels adjacent to each other by adhering tiles to a base material having a frame on the edge of the back side, and to attach the tile wall panels to each other through the frame. This method involves forming in advance a U-shaped bar-shaped joining tool consisting of a threaded part and a rotation stopper arranged substantially parallel to each other, and a bent part that connects the two. In the vicinity of the coaxial communication hole formed in the frame, one working hole is formed in the part of the base material where tiling of one of the tile wall panels is omitted, and from the surface side of the tile wall panel. Guide the joining tool to the back side through the working hole, insert the threaded part into the communication hole of the adjacent frame to expose the tip of the threaded part from the frame, tighten the nut to the threaded part, and tighten both screws. Tile wall A, in which the working hole is covered with tiles after the tile wall panels are closely joined together. This is a method of joining flannel.

Further, the second invention provides a U-shaped rod and a nut that is screwed into the threaded portion from the threaded portion and the rotation stopper that are arranged substantially parallel to each other, and the bent portion that connects the two to each other. This is a joining tool used to join the tile walls/walls and flannel provided.

[Example] The present invention will be described in detail below with reference to FIGS. 1 to 4. In the present invention, the structure of the tile wall/9-nel vertical frame 1 is the same as that shown in Fig. 7 (second method), and the number of working holes is also the same as that shown in Figs. 8 and 9 (third method). Similarly, there is one joint for one joint. However, the joining tool (corresponding to the prior art bolt) is different. Therefore, the joining tool will be mainly explained here.

As shown in the figure, the coupling tool 12 has threaded portions 1 that are substantially parallel to each other.
3. A substantially U-shaped steel rod consisting of a rotation stopper 14 and a bent part 15 connecting the two, and a nut 1 screwed into the threaded part 13
6. The rotation stopper 14 may have the same length as the threaded part 13, but it is preferably longer than the threaded part 13 because it also serves as a grip for the worker to grasp with his/her hand. Further, when the rotation stopping portion 14 is short, an extension tool (not shown) can be used to cut a thread in the core portion and screw it into the core portion.

1 and 2 show the case of planar coupling. In the figure, for example, in the tile wall panel on the left, one tile 4 near the communication hole 6 is omitted during factory production, and a working hole 7, which is slightly smaller in area than the tile 4, is drilled in the base material 3 of that area. There is. Two tile wall panels are erected adjacent to each other just in front of the frame wall surface, and the rotation stopper 14 of the joining tool 12 is grasped with one hand and guided into the working hole 7, and the connecting tool 12 is inserted into the communication hole 6 of both tile wall panels. Insert the threaded part 13 through. A nut 16 is tightened at the tip of the threaded portion 13 exposed from the vertical frame 1 to tightly connect both tile wall panels to each other. When the nut is hooked, the rotation stopper 14 sometimes comes into contact with the back surface of the vertical frame 1 to prevent rotation of the joining tool, so that the above-mentioned joining operation is easy and reliable. When the bonding is completed, the work hole 7 is closed with the tile 4 using adhesive.

FIG. 3 shows a corner bond. FIG. 4 is a diagram showing a case where a tile wall panel is joined to another irregularly shaped panel 17 (for example, made of FRP).

〔Effect of the invention〕

Since the present invention is constructed as described above, there is no need to weld the case nut to the vertical frame or angle member as shown in FIGS. 8 and 9. In the above description, the vertical frames are connected to each other to connect the tile wall panels in the horizontal direction, but the horizontal frames can also be provided with similar communication holes and connected in the vertical direction.

Furthermore, the edges of the base material may be bent toward the back side to form seven run sections, and the seven run sections may constitute each frame to join the tile wall panels. Embodiments also allow tile wall panels to be easily combined with other tile wall panels or with non-tiled panels.
