Abstract

PURPOSE:To execute fitting work efficiently by setting a bearing metal-plates having a slit with an end open, on the upper surface of a beam, to provide the frame body of an external wall panel with a bolt slot long in the horizontal direction, and by inserting the panel into the slit from an upper section, to be fixed with bolts. CONSTITUTION:On the upper surface of a beam 1, an L-shaped bearing metal- plates 3 having a slit 11 with an end open is fixed with a bolt 7. On a horizontal frame 17 at the upper and lower ends of an external wall panel 12, a plate 19 having bolt slots long in the horizontal direction is firmly fitted. After that, in a state that bolts 27 are temporarily set on the horizontal frames 17, they are inserted into the slit 11 from the lower side panel 12 and after that, the frames 17 are fixed with the bolts 27. Hence, the external wall panel 12 can be easily fitted on.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching exterior wall panels to the frame of a building.

0002

2. Description of the Related Art In buildings having a frame-panel structure in which walls are constructed by attaching exterior wall panels to the steel framework of a building, it is necessary to provide a structure for attaching the exterior wall panels to the framework. As such a structure, a method is widely adopted in which a supporting metal fitting is attached to the framework in advance and the outer wall panel is fixed to this with bolts. In this case, a bolt hole is formed in the support metal fitting, and the support fitting is tightened and fixed with a bolt inserted into the bolt hole.

0003

[Problem to be Solved by the Invention] In the mounting device using the above-mentioned support fittings, the bolt holes of the external wall panel suspended by a crane are aligned with the bolt holes of the support fittings while the panel is suspended. In this state, insert the bolt and tighten it. However, it is very difficult to insert and tighten the bolts in an unstable state where the bolt holes are aligned while the device is suspended, and the installation requires time and effort. Another problem was that the vertical height of the exterior wall panel could not be adjusted using conventional bolt holes.

[0004] The present invention aims to eliminate such conventional drawbacks.

[0005]

[Means for Solving the Problems] In order to solve the above problems, in the present invention, a slit with an open upper end is provided in a support member attached to a frame of a building, and a bolt inserted into the bottom side of the slit is attached to an outer wall. The upper end of the panel is fixed, and the lower end of the outer wall panel disposed above the outer wall panel is fixed with a bolt similarly inserted into the upper side of the slit.

[0006] In the above, it is conceivable to make the bolt hole of the outer wall panel into which the bolt is inserted into a long hole that is elongated in the horizontal direction.

[0007]

[Operation] Make the bolts protrude from the side of the exterior wall panel in advance, and while lowering the exterior wall panel suspended from above, insert the bolt at the top end of the panel into the slit in the support member, adjust the vertical height, and tighten. . Furthermore, the horizontal position of the outer wall panel can be adjusted within the range of the bolt holes in the outer wall panel.

[0008]

[Example] In the figure, 1 is H that constitutes the framework of the building.
The beam is made of shaped steel, and a support fitting 3 as a support of the present invention is attached to the upper surface of a flange 2 on the upper side of the beam 1. This support fitting 3 is made by bending a metal plate into an L shape when viewed from the side, and welding a rib plate 4 to the inside of the corner.A horizontal mounting part 6 is installed on the top surface of the beam 1 and bolts 7 is fixed. A gauge slit 9 for adjusting the gap between the panels is formed at the center in the left-right direction of the other vertical support part 8 to a certain depth from the upper end. On both sides of this gauge slit 9, slits 11, 11 for fixing the panel are similarly formed to a certain depth from the upper end.

Reference numerals 12 and 13 denote a pair of upper and lower outer wall panels, in which a frame 16 made of a C-channel frame body joined in a rectangular shape is integrally attached to the back side of a main body 14 made of concrete. Notches 18 are formed at both ends of the upper and lower horizontal frames 17 near each corner of the frame 16, and a rectangular plate 19 is attached to cover the notches 18 from the outside.
A long bolt hole 21 is formed in the left-right direction. Further, on the back surface of this plate 19, there is a nut engaging portion 2 consisting of a pair of vertically parallel elastic horizontal pieces 22 and a vertical piece 23 with the tips of each horizontal piece 22 bent perpendicularly in the mutual direction.
4 is formed. A nut 26 is attached to the engaging portion 24 so as to be engaged with the engaging portion 24 from the side in a rotated state.

In the above structure, the bolts 27 are inserted in advance from the outside into the bolt holes 21 at the upper end of the lower outer wall panel 13 of the pair of upper and lower outer wall panels 12 and 13 shown in the figure, and engaged as described above. Temporarily install this bolt 27 by screwing it into the nut 26 that was attached to the bolt 26. In this state, insert the bolt 27 at the upper end of the outer wall panel 13 suspended from above into the fixing slit 11 on one side of the support fitting 3 from above. In this state, tighten the bolts 27 to some extent, and connect the long holes 21 and slits 1 of the outer wall panel 13.
While shifting it up, down, left and right within the range 1, position it up and down, and finally tighten and fix it. Further, the bolt hole 21 at the lower end of the upper side outer wall panel 12 is aligned with the upper side of the same slit 11, and the bolt 27 is similarly inserted from the slit 11 side and screwed into the nut 26 on the back side and tightened and fixed. In this case, bolts 27 may be attached in advance in the same way as on the upper side. Further, the lower end side of the lower outer wall panel 13 in the figure is also attached in the same manner as the upper outer wall panel 12 in this figure. Furthermore, an outer wall panel is attached to the left side of each of the outer wall panels 12 and 13 in FIG.
It is fixed using. At this time, the central gauge slit 9 serves as a gauge for the joint width between the two, and the left and right positions of the outer wall panels 12 and 13 are adjusted to match the width of the slit 9.

[0011]

As described above, according to the present invention, the bolts are made to protrude from the side surface of the exterior wall panel in advance, and the bolts at the upper end of the panel are inserted into the slits of the support member while lowering the exterior wall panel suspended from above. At the same time, since all you have to do is adjust the vertical height and tighten, there is no need to align the bolt holes while inserting and tightening the bolts as in the conventional case, making the installation process very easy. It has the advantage of being able to adjust the height up and down within the range of the slit. At this time, since both the upper end of the lower side panel and the lower end of the upper side panel are attached to the same slit, even when using support metal fittings, there is no need to use separate metal fittings, and there is an effect that the number of parts can be reduced. Furthermore, since the bolt holes in the outer wall panel are elongated holes that are long in the left-right direction, the left-right position can also be adjusted.
