Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating joints in construction methods for pre-built houses, etc., for eliminating joints that form between exterior wall panels or between exterior wall panels and sashes.

Conventionally, this type of joint treatment method has been carried out by driving gaskets 3 into joints 2 that occur between outer wall panels 1, 1, etc., as shown in FIG.

Therefore, in this treatment method, the gasket 3 inevitably protrudes from the outer wall panels 1, 1 at intervals of 1 m or 2 doors, spoiling the appearance, and if the gaps between the joints 2 are misaligned, the gasket 3 cannot be installed reliably. The problem was that I couldn't do it.

The present invention eliminates the drawbacks of such conventional methods and completely eliminates the exposure of joint areas, and
To provide a new joint treatment method that can reliably perform joint treatment regardless of the size of the gap between the joint parts.

The method of the present invention will be explained based on a diagram showing an embodiment. In FIG. 2, ii and il are two shaft members formed of a C channel and forming a framework of a lightweight steel structure , 12, 12 are external wall panels made of a front member 13, a back member 14, and a heat insulating material 15 such as foamed plastic sandwiched between both members 13, 14. In the section, there is a mounting bracket 16 as shown in the figure that holds down the back member 14, and a bolt 1 screwed into the mounting bracket 16 and interposed between both shaft members ii and 1i.
7 is fixed to the outer surface of the shaft member ILII.

Reference numeral 18 denotes a decorative plate attached to the surface of the surface member 130, the end portion 19 of which is bent toward the back surface of the surface plate 13.

Now, with the above structure, both exterior wall panels 12.12
To explain the method for treating the joints 20 that occur between the surface members 13 and 13, first, as shown in FIGS. and insert it into the back side of the joint 20.

Trapezoidal support holes 22 as shown in the figure are bored in this support plate 21 at intervals of about 2507ffffi, and when the support plate 21 is brought to the center of the joint 20, When the wide side part of the trapezoidal support hole 22 is inserted into the tip of the bolt 17 screwed into the mounting bracket 16 and then the support plate 21 is pulled downward, the narrow part of the trapezoidal support hole 22
It is locked and fixed by the threaded part of.

These locking portions may be provided at approximately three locations per joint 20: the upper end, the lower end, and the middle.

After installing the support plate 21 in this way, the fifth
As shown in the figure, the backing plate 23 bent to have a W-shaped cross section is inserted into the back side of the joint 20 diagonally from the joint 20 in the same manner as described above, with the bottom of the W-shape facing outward. Bring it to the center.

This backing plate 23 is provided with perforated holes at a pitch of approximately 250ffi777, and when the tapping screws 24 are screwed into the perforated holes from the outside, as shown in FIG. , the above-mentioned support plate 21 is connected to the tapping device 2
4, it bends and hits the shaft members ii, ii on the back side.

Then, if you turn it again as if screwing it in, this time,
The backing plate 23 floats forward, that is, outward, and comes into close contact with the back surface of the top plate 13, specifically, the end portion 19 of the decorative plate 18, and the seventh
As shown in the figure, close the joint 20 part.

After attaching the backing plate 23 in this way, as shown in FIG. 8, the joint 20 is filled with putty 26 using a trowel 25 or caulked, and if necessary, the putty 26 is applied as shown in FIG.
The paint 27 is sprayed onto the outer surface of 6 and the outer surface of the surface member 13 to finish.

Before this spraying, it is desirable to handle the surface of the trowel 281/i so that it is smooth. Also, when filling the putty 26, remove dirt, oil, etc. from the joints 220 with thinner, etc. It is desirable to remove the putty 2.
Epoxy resin is most suitable for No. 6.

In the above structure, the shape of the backing plate 23 is not limited to the above one, but by making it W-shaped, a rib effect is produced and high strength can be obtained. , high watertightness can be obtained.

Further, the support plate 21 is for supporting the tip of the tapping pin 24, and as will be described later, there is no need to provide it if there is an alternative.

Fig. 10 and the following show other embodiments of the present invention. Fig. 10 shows a method in which a backing plate 23 having a generally flat plate shape as shown in the figure is used, and two tapping screws 24, 24 are screwed in diagonally. , the tip thereof is supported by the back members 14, 14 of the outer wall panels 12, 12, specifically, the U-shaped panel frame 29 fitted between the back member 13 and the back member 140. FIG. 11 uses a backing plate 23 having a generally trapezoidal shape.

Moreover, FIGS. 12 to 14 show an embodiment in which the approximately ■-shaped backing plate 23 is used, and the backing plate 23 in FIG.
It is fixed to the side wall 31 with another screw 30.

The present invention has the above-described configuration, and the method of the present invention includes inserting a backing plate into the joint portion to close the joint portion, and screwing screws into the backing plate from the outside. By rotating the tip of the screw in contact with the supporting part on the back side of the backing plate, the backing plate is floated and supported, and then the joint part is filled with putty from the outside. It is characterized by applying caulking or caulking and finishing by applying paint to the outer surface if necessary, so unlike the conventional gasket filling, the joint part does not protrude and the appearance is beautiful. In particular, by spraying paint on the surface of the putty and exterior wall panels, it is possible to completely eliminate the exposure of the joints, and the bottom joints can be created with caulking. In addition, since the joint portions do not protrude in this way, it becomes easy to perform surface work such as tiling.

In addition, in the present invention, even if there is a considerable error in the gap between the joints, the work can be carried out without any inconvenience, and the work is extremely easy because the method of the present invention can be worked entirely from the outside.

In addition, if a support plate is provided on the back side of the backing plate as in this embodiment, the gap between the frame channels can be closed by this support plate, and blow-through can be prevented in the event of a fire. It is possible to obtain a fire protection effect.
