[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer wall unit and an outer wall construction method, and more particularly, in the construction of an outer wall of a high-rise building such as a large building, while using a large number of outer wall panels filled with a core material between front and back metal skins. In particular, the present invention relates to a technique for significantly improving the workability and, in particular, for preventing deformation and breakage caused by applying a great load to the connection portion between the connection concave portion and the connection convex portion of the upper and lower outer wall panels.
[0002]
[Prior art]
Recently, to construct the outer wall of the building, as shown in FIG. 2, the core material 3 is filled between the front and back metal skins 1 and 2, and the connection concave portion 4 is provided on one of the upper and lower portions, and the connection convex portion 5 is provided on the other side. The use of the outer wall panel 6 formed with the structure has been widely used because the appearance of the building can be remarkably enhanced and the heat insulation and weather resistance can be sufficiently enhanced.
[0003]
By the way, each of the outer wall panels 6 as described above is fixed to the wall base with the fixture 17 and requires a huge amount of scaffolding. In a large building, a large amount of work is required and the construction period is prolonged. Yes, in high-rise buildings, it is difficult to construct a scaffold, and construction may be difficult.
[0004]
[Problems to be solved by the invention]
As a means for solving such a problem, a construction method in which a large number of outer wall panels are attached to a unit frame, a wall unit is assembled, and the wall unit is lifted and connected by a crane has been considered and proposed.

The unit frame 7 is configured by connecting them equally, and a plurality of horizontally long outer wall panels 6 are fixed to the trunk edge 15 of the unit frame 7 by a fixing tool 17. The outer wall panel 6 is, for example, one having a horizontal dimension of 3960 mm and a vertical dimension of 910 mm, which is, for example, pasted up to seven on the top and bottom. The height of the outer wall unit A is set to a height corresponding to the height of each floor of the high-rise building. Such an outer wall unit A can be assembled at an arbitrary place such as a construction site of a high-rise building or a factory.
[0015]
As shown in FIG. 2, the outer wall panel 6 is filled with a core material 3 made of an inorganic material such as rock wool between the front and back metal skins 1 and 2 and connected to the upper side with a connection recess 4 on the other side. The convex part 5 is formed. A fixed recess 20 is formed in the front portion on the connection concave portion 4 side, and a cover portion 21 is formed on the front portion on the connection convex portion 5 side. Then, the fixing tool 17 is driven into the fixing recess 20 to fix the upper portion of the outer wall panel 6 to the trunk edge 15, and the connection convex portion 5 of the upper outer wall panel 6 is fitted and connected to the connection concave portion 4. In this case, the cover 21 is engaged with the fixing recess 20 to hide the fixing tool 17. A watertight packing 22 is interposed at such a connecting portion in the vertical direction to ensure sufficient watertightness.
[0016]
As shown in FIGS. 1 and 3, a receiving member 23 formed with a fitting recess 9 allowing sliding is fixed to the upper end portion of the vertical frame 16 by a bolt 24 and protrudes upward.

Thus, the bolt 28 and the guide pin 29 which are the fitting convex part 10 are connected to the sliding groove 25 of the fitting concave part 9 which permits sliding while maintaining the vertical direction. In this case, the adjustment bolt 31 is protruded downward by judging the degree of fitting between the connection concave portion 4 and the connection convex portion 5 of the upper and lower outer wall panels 6 and 6 between the upper outer wall unit A and the lower outer wall unit A. Fine adjustment in the vertical direction is performed, and the adjustment bolt 31 is applied to the receiving material 36 and temporarily fixed before the connection concave portion 4 and the connection convex portion 5 are completely connected. Thus, when the upper and lower outer wall units A, A are connected, it is possible to reliably prevent the load of the upper outer wall unit A from being applied to the lower outer wall unit A. The connection recesses 6 and 6 can be connected to the connection protrusions 5 in a predetermined manner, and it is possible to avoid applying a great load to the connection locations, so that the connection locations of the upper and lower outer wall panels 6 and 6 can be reduced. Deformation and damage can be reliably prevented.
[0020]
In this case, the temporary fixing means 13 is located on the indoor side, and is provided at a position where the connection between the upper and lower connecting concave portions 4 and the connecting convex portions 5 can be visually observed when the temporary fixing means 13 is operated. According to such a configuration, when performing fine adjustment of the fine adjustment portion 14 in the temporary fixing means 13, the upper and lower outer wall panels 6, 6 are visually inspected with respect to the connection state between the connection concave portions 4 and the connection convex portions 5. Fine adjustment can be performed, and the connection concave portions 4 and the connection convex portions 5 of the upper and lower outer wall panels 6 and 6 can be connected in a predetermined manner.
[0021]
6 shows a horizontal cross-sectional view, FIG. 7 shows an enlarged cross-sectional view, and shows a watertight connection structure of the outer wall units A and A in the lateral direction.
[0022]
A side end piece 40 is bent at a lateral end of the outer wall panel 6 so as to face the core member 3 with a space therebetween, and a receiving piece 41 is bent following the side end piece 40. A seal packing 42 is interposed between the side end piece 40 and the core material 3. Both ends of a flat U-shaped housing 43 are press-fitted into the back portions of the left and right seal packings 42, 42. The side end pieces 40, 40 of the adjacent outer wall panels 6, 6 are filled with a modified silicone resin 44 as a caulking agent. The housing 43 is supported via a support piece 46 on a column member 45 having substantially the same height as the outer wall unit A. Such a frame 43 and the pillar material 45 are installed in each floor unit. In this case, the column member 45 is attached to the structure 33 side, and the housing 43 is connected by a housing connecting material (not shown).
[0023]
By the way, in the outer wall unit A, a plurality of outer wall panels 6 at the upper and lower intermediate portions are not attached, and a sash 39 is inserted into this portion to form a window and a window glass is inserted to form a continuous window in a high-rise building. It is also possible.
