Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for joining wall frameworks for joining adjacent wall frameworks in a wooden unit house.

[Prior Art] In wooden unit houses, the wall frameworks that make up the wall surfaces are interconnected and unitized at the assembly stage in a factory.

When connecting wall frames, it is necessary to connect the lower frame members of the wall frames to each other, and for this purpose, nails or the like are driven from the bottom surfaces of the lower frame members to perform the connection.

Alternatively, as a method of connecting the lower frame members, as shown in FIG. 5, the lower frame members 10a of the wall frame 10 are doubled, their stepped ends 10b are overlapped, and nails 11 are driven from above to join them. A method was adopted to do so.

[Problems to be Solved by the Invention] However, as in the past, in order to drive nails etc. from the lower surface of the lower frame material of a wall frame, it is necessary to first lay down the wall frame sideways and raise the lower surface of the lower frame material upward; Alternatively, it was necessary to work from underneath the wall frame while it was suspended, resulting in extremely poor workability.

Further, even when the lower frame material is made double, there are problems in that the material cost of the lower frame material increases and the processing of the joint portion is troublesome.

The present invention has been made in order to solve the above-mentioned conventional problems, and provides a method for joining form frames in wooden unit houses, which makes the assembly work of form frames extremely easier than in the past, and also ensures strong joints. is intended to provide.

[Means for Solving the Problems] In order to achieve the above object, the method for joining formwork in a wooden unit house of the present invention is a method of joining a form frame in a wooden unit house of the present invention. Fix the metal fittings on a workbench with the cutting edge facing up, place the lower end of the formwork that makes up the framework structure on approximately half the area of the top surface of the wood connecting metal fittings, and press it from above. The lower end of the other formwork is placed on the remaining half area of the wood connecting fitting and pressed against it from above, thereby joining the lower parts of the two formworks. .

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

Fig. 4 is a perspective view of a building unit composed of n-sets of walls, and Fig. 1 shows the state in which the formwork is joined using the joining method of the present invention. FIG.

In each of the above figures, the building unit 5 is composed of four formwork sets 1 and a ceiling panel 2, and the four formwork sets 1 are joined by butting adjacent formwork sets 1 against each other. Then, the ceiling panel 2 is placed on the assembled formwork 1 and joined.

The formwork 1 is made up of upper and lower frame members 1a and a plurality of vertical frame members 1b, and has an external wall plywood IC attached to the outdoor side thereof.

Adjacent formworks 1 are nailed over the entire butt portions of each other, and the lower frame members 1a are joined by wood connecting fittings 3.

As shown in FIG. 2, the wood connecting fitting 3 is made by cutting and raising a substantially rectangular metal plate at multiple locations by shearing and bending using a press molding machine or the like to form a plurality of cutting blades 3a protruding from one side. It is what it is. In the example, a diagonal cut is made in the center of the two cuts so that two cut edges 3a are formed for the cuts at - places, and the cut cuts are raised on both sides to form two cuts. It forms a blade 3a. The tip of the cutting blade 3a is formed into a sharp mountain shape by making an oblique cut in the center, so that it can be press-fitted into wood or the like.

However, various types of wood connecting fittings 3 can be used, and the cutting blade 3a may be formed by a method other than cutting and raising.

As shown in Fig. 1, the lower frame material la of the adjacent formwork l is
They are connected by this wood connecting fitting 3. That is, a wood connecting fitting 3 is attached to the lower surface of the end of the lower frame material 1a of one formwork l.
By abutting approximately half the area of the upper surface, and abutting the remaining upper surface of the wood connecting fitting 3 against the lower surface of the end of the lower frame material 1a of the other formwork 1, and pressing them together, the cutting blade 3a is
is cut into the lower frame material 1a to perform the joining.

Next, the method of joining the formwork according to the present invention will be explained with reference to FIG.

FIGS. 3(a) to 3(e) are perspective views showing the assembly procedure of wall # group according to the present invention.

In FIG. 3(a), 5 is a workbench, and the wood connecting fitting 3 is placed and fixed on this workbench 5.

In this case, the wood connecting fittings 3 are placed at corresponding locations on the corners of the formwork l, and fixed by arbitrary fixing means such as magnets.

Next, as shown in FIG. 3(b), one wall frame 1 is lifted up by a crane 6 and lowered onto the wood connecting fittings 3.

In this case, the lower end of the lower frame member 1a of the wall framework 1 is placed on a half area of the upper surface of the wood connecting fitting 3. Then, this wall frame 1 is pressed from above by any pressing means, and the cutting blade 3a of the wood connecting fitting 3 is bitten into the lower frame material 1a of the wall frame 1.

Then, as shown in FIG. 3(C), the second wall framework 1 is lifted up by the crane 6 and lowered so as to be orthogonal to the first wall framework 1. At this time, one lower end of the lower frame member 1a is placed on the remaining half area of the wood connecting fitting 3, and the other lower end is placed on the other wood connecting fitting 3. Similarly, when the wall frame l is pressed from above, the cutting blade 3a bites into the lower frame member 1a, and the lower frame members 1a of the two wall frames L are joined together.

The four wall frames 1 are successively joined by the same method (FIGS. 3(d) and (e)). The wall frames 1 are further connected at their abutting surfaces with a large number of nails. Finally, the ceiling panel 2 is placed on the assembled wall framework 1 and joined with nails, etc., to complete one building unit 4 (Figure 4).
.

A plurality of building units 4 configured in this manner are stacked or arranged side by side to form one building.

[Effects of the Invention] As explained above, the present invention connects wall frames by using a wood connecting fitting having a plurality of protruding cutting blades, which makes it easier to connect the lower frame material of the wall frame. In addition, there is no need to lay down the wall frame or double the lower frame material as in the past, and the wall frame can be joined extremely easily.

In addition, since the wood connecting metal fittings have multiple cutting blades, the connection of the wall framework can be made firmly, and after connection, the wood connecting metal fittings have the effect of fitting well along the bottom frame material. be.
