Description

[Detailed Description of the Invention] This invention is applicable to repair, renovation,
This article relates to the method of fixing the ALC outer wall, especially the wall joints used to connect the temporary scaffolding and the ALC outer wall during construction.

In general, when connecting walls in temporary construction, if the external wall components are made of reinforced concrete, etc., which can be expected to have high material strength, hole-in anchors, etc. are driven into the wall surface regardless of whether it is a new construction, repair, or renovation. It is constructed by tightly connecting a frame, a steel pipe, etc. with a connecting fitting whose one end is connected.
On the other hand, if the external wall components are not expected to have material strength such as ALC panels, when building a new building it is possible to connect them to the connecting fittings in the same way as described above using cap nuts, etc., which are attached directly to the building frame. The above method cannot be used. Therefore, it is possible to use hanging walls or waist walls of wall openings and connect them with steel pipes, etc., or to install protrusions between them and the walls of adjacent buildings. Currently, methods such as sewing together bolts together with the backing plate are used.

However, the process of connecting walls during repairs and renovations is not only complicated, it is also difficult to secure the specified quantity of connections due to restrictions on wall openings and adjacent buildings, and due to the interior finish. There are drawbacks such as the troublesome process of dealing with damage when removing scaffolding, including repair work.

This invention solves the above-mentioned drawbacks, and does not depend on the presence or absence of openings in the wall, the presence or absence of adjacent buildings, and the condition of the interior wall finish.
The purpose is to provide an extremely simple method for fixing the external wall side of a wall connection for an ALC external wall, and the structure is such that the ALC panel mounting joint of the ALC external wall is rotatably supported in the middle part, and the joint part A fixing fitting having a penetration part consisting of a pair of plate-shaped members shaped so as to be able to hold the joint mortar is used, and the penetration part of the fixing fitting is driven into the horizontal joint sealing part of the joint part, and the joint reinforcing bar of the joint part is driven in. By sandwiching and fixing the joint mortar containing the
A feature is that the wall joint is fixed to the ALC outer wall via the fixing fitting.

The details will be explained below based on the drawings.

First, the fixture used in this invention will be explained based on FIG. 1.

In FIGS. 1A and 1B, the fixture 1 is comprised of a pair of plate-like members 2 and 3 rotatably supported by a pin 4 or the like at an intermediate portion. Each plate member 2,
3 are penetration parts 2a, respectively, with the pin 4 as a boundary.
3a and arm portions 2b, 3b. One of the penetration parts 2a is formed straight, but the other penetration part 3a is formed between the straight penetration part 2a and the inside, as will be described later.
In order to constitute the space 5 in which the joint mortar 16 containing the joint reinforcing bars 13 is inserted in the ALC panel mounting joint portion, it is formed into, for example, a dogleg shape, a C shape, or an L shape. Moreover, the penetration parts 2a, 3a
It is preferable to provide tapered blades 2a' and 3a' at the tips of the blades to facilitate driving into the ALC panel.

The arm portions 2b and 3b are provided with locking holes 6 and 7, respectively, which overlap with each other while sandwiching the joint mortar.

In other words, by overlapping the locking holes 6 and 7, the joint mortar 16 is sandwiched between the penetration parts 2a and 3a (see FIG. 1B).

Further, at the rear end of one of the arms 2b and 3b (2b in the drawing), a means 8 for connecting to a scaffold-side fixing device (not shown) is provided. In the drawing, a cap nut is provided as the connecting means 8 in alignment with the axis of action with the joint mortar to prevent eccentric force from being applied. It is also possible to provide coupling means 8 such as , turnbuckles or the like. Note that 9 is a reinforcing sill for driving.

Next, using the fixing fitting 1 having the above-mentioned configuration,
The method of fixing the ALC exterior wall joint to the exterior wall will be explained based on FIGS. 2 and 3.

In FIG. 2, first, the configuration of a typical ALC outer wall will be explained. An ALC panel 12 is temporarily fixed to a through angle 11 fixed to a beam (not shown), etc., and joint reinforcing bars 13 are welded to the through angle 11 in advance. The ALC outer wall is constructed by passing it through the panel mounting hardware 14 and inserting it into the panel joint part 15, and then injecting joint mortar 16 into the joint joint. At the ALC panel 12 attachment joint part 17 of such an ALC outer wall, the fixing metal fitting 1 is driven into the side joint sealing part 18 so as to sandwich the joint mortar 16 containing the joint reinforcing bar 13 of the joint part 17. The outer wall side of the wall connection is fixed.

This will be explained in further detail based on FIG.

At the ALC panel 12 mounting joint part 17, first, from behind the arm part 2b of the plate member 2 of the fixing fitting 1, as shown by arrow A, cross joint sealing part 1
8 to the bottom surface of the panel mounting hardware 14, the penetration part 2a
The joint reinforcing bars 13 are inserted so that they are in contact with the outer periphery of the joint mortar 16 containing the joint reinforcing bars 13 (FIG. 3, a). Next, as shown by arrow B, the reinforcing ear 9 portion of the plate-shaped member 3 is rotated around the pin 4 so that the joint mortar 16 is sandwiched between the penetration portion 3a and the penetration portion 2a. (Figure 3, b).
By continuing to press the reinforcing ear 9, the locking holes 6 and 7 provided in the arms 2b and 3b overlap,
The insertion of the joint mortar 16 between the penetration parts 2a and 3a is completed.

By bolting these overlapping locking holes 6 and 7, the outer wall side of the ALC outer wall wall connection is fixed, and the wall connection is constructed by connecting a fixing device on the scaffolding side (not shown) with a connecting means 8. (Figure 3c).

In addition, in the embodiment of the drawing, the side joint sealing part 1
8 toward the bottom surface of the panel mounting hardware 14, but the fixing hardware 1 can also be driven toward the top surface of the panel mounting hardware 14, not limited to the illustration. In this case, It is desirable that the tapered blades 2a' and 3a' be tapered upside down, opposite to that shown in the drawings.

As explained in detail above, according to the method of fixing the outer wall side of the wall joint for ALC outer walls of the present invention, extremely simple fixing fittings can be easily attached to the ALC outer wall regardless of the presence or absence of wall openings. You cannot expect the material/strength to improve just by hammering it into the material.
Since joint mortar containing joint reinforcing bars is sandwiched against the ALC exterior wall, the exterior wall can be firmly fixed. Furthermore, when the scaffolding is removed after construction is completed, the fixing metal fittings can be easily pulled out, damage disposal is easy, and the fixing metal fittings can be used repeatedly.
