Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing a wall joint used for connecting temporary scaffolding and an ALC outer wall in repair, renovation, and construction among various construction works, particularly on the ALC outer wall side.

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 component material is not expected to have feed strength, such as ALC panels, when building a new building, it can be connected to the connecting fittings in the same way as described above using a bag nand etc. that is attached directly to the frame, but when repairing or renovating a new building, You can take the above method at any time. Therefore, the hanging wall of the wall opening, Ii
using a wall and connecting with steel pipes, or in close proximity, j
++・81f, the current method is to use a method of installing a support between the building wall, or even a method of directly drilling a hole in the wall and sewing it together with a backing plate on the inner wall using a bolt. .

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

This invention solves the above-mentioned drawbacks, and the presence or absence of openings in the wall,
Alternatively, the purpose is to provide an extremely simple method for fixing the external wall side of the ALC external wall connection, which is not affected by the presence or absence of adjacent buildings and the condition of the internal wall finish, etc. A fixing metal fitting is driven into the ALC panel mounting joint pressure part of the outer wall from the side joint sealing part so as to sandwich the joint mortar containing the joint reinforcement of the joint part.

The details will be explained below based on the drawings.

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

Figure 1 0), (In Ron, the fixing metal fittings are in the middle.

q A pair of plate members 2 rotatably supported by hinges etc.
, and 3 to (14). Each plate member 2.3 has a penetration portion 2a with the bottle 4 as a boundary.

3a and arm portions 2b, 3b. One of the penetration parts 2a is formed straight, while the other penetration part 3a has a joint between it and the straight penetration part 2a that includes a joint bar 13 in the ALC panel mounting joint pressure part, which will be described later. In order to constitute the space 5 in which the mortar 16 is inserted, it is formed into, for example, a dogleg shape, a C shape, or an L shape. Also, penetration part 2
It is preferable to provide tapered blades 2 a' and 3 a' at the tips of a and 3 a to facilitate driving into the ALC channel.

The arm portions 2b and 3b are each provided with a locking hole 6.7 that overlaps with the joint mortar sandwiched therebetween.

Conversely, by overlapping the locking holes 6.7, the joint mortar 16 is sandwiched between the penetration parts 2a and 3a (see FIG. 1(b)).
At the rear end of one of the b13b (2b in the drawing), a means 8 for connecting with a fixing device (not shown) of the scaffold 1iijl is provided. In the drawing, a cap nut is provided as the connecting means 8 along the axis of action with the joint mortar to prevent force from being applied due to eccentricity. It is also possible to provide connection means 8 such as , hooks, turnbuckles, etc. Note that 9 is a reinforcing sill for driving.

Next, a method of fixing the outer wall side of the ALC outer wall joint using the fixing fitting 1 having the above-described structure will be explained based on FIGS. 2 and 3.

In FIG. 2, first of all, the configuration of a general ALC outer wall will be explained. The h L C/: flannel 12 is temporarily fixed to the through angle 11 (not shown) identified in The ALC outer wall is constructed by passing it through the panel mounting hardware 14 welded to the angle 11 and inserting it into the panel base portion 15, and then injecting joint mortar 16 into the joint joint. This ALC outer wall ALC panel 12 installation installation joint part 1
7, the fixing metal fitting 1 is driven into the side joint sealing part 18 so as to sandwich the joint mortar 16 including the joint reinforcing bars 13 of the joint part 17, thereby fixing the outer wall side of the ALC outer wall connection.

This will be explained in more detail with reference to FIG.

Attach the ALC panel 12 to the mounting joint 17. First, from behind the arm portion 2b of the plate-like member 2 of the fixing fitting 1, as shown by arrow A, insert the penetration portion downward from the side joint sealing portion 18 into the panel mounting hardware 14. The joint mortar 2a is driven in so that it contacts the outer periphery of the joint mortar 16 containing the joint reinforcing bars 13 (FIG. 3, (&)). Next, as shown by the arrow B, the reinforcing ear 9 portion of the plate-like member 3 is rotated around the bin 4, and the joint mortar 16 is inserted between the penetration portion 28 and the penetration portion 28.
(Figure 3, (b)). Furthermore, by continuing to hit the reinforced ear 9 part, the arm part 2b is created.

The locking holes 6.7 provided in 3b overlap, and the penetration part 2a,
(Insertion of joint mortar 16 by 3m is completed.

Bolting this overlapping locking hole 6.7 KJ:

is fixed, and the fixing device (4) of the scaffold 11 (not shown) is fixed.
By connecting them by the connecting means 8, a 9) peg is constructed (FIG. 3(C)).

In the embodiment shown in the drawings, the fixing fitting 1 is driven from the horizontal joint sealing part 18 toward the bottom surface of the panel mounting hardware 4; On the other hand, it is also possible to drive the fixing metal fitting 1, and in this case, it is likely that the tapered blades 2j, 3a' are tapered upside down as opposed to the illustration.

As explained above in detail +r (tl), according to the method of fixing the outer wall +1ill in the wall joint for the ALC outer wall of the present invention, it is possible to fix the outer wall +1ill on the ALC outer wall without depending on the presence or absence of the wall+f+i opening, etc. By simply inserting the 17ii simple fixing fittings into the ALC exterior wall, where 71A material and strength cannot be expected, the joint mortar containing the joint reinforcing bars is sandwiched, allowing for a strong fixation on the exterior wall side. can.

Furthermore, when construction is completed (12≦scaffolding), the fixed metal can be easily pulled out, damage disposal is easy, and the fixed metal can be used repeatedly.
