Description

TECHNICAL FIELD The present invention relates to a construction method for attaching a wall panel to a building frame such as a steel beam.

<Prior Art> As a construction method for attaching the upper-layer wall panel and the lower-layer wall panel to the building frame, construction methods using various fasteners and mounting bolts have been conventionally implemented and proposed.

For example, in Japanese Examined Patent Publication No. 63-54101, as shown in FIG. 8, an L-shaped ruler angle 62 mounted on a steel beam 61 and a groove for meshing with the L-shaped ruler angle 62 are provided, and a cavity 63 having a rectangular cross section is provided. Tabs 64 and the flat tabs attached to the upper wall panel P ₂
A lower mounting wall panel using a first mounting member composed of 65 and a second mounting member mounted on the lower wall panel P ₁ and formed of an insert piece 66 inserted into the gap 63. Attach P ₁ to the building frame and upper wall panel
Install P ₂ .

<Problems to be solved by the invention> In the above installation work, in order to follow the interlayer displacement and to have a certain wind pressure resistance performance, the interconnection and the entrance adjustment of the upper and lower wall panels, and the height adjustment Each adjustment and connection work such as adjustment becomes complicated. Therefore, the construction time is prolonged and the construction cost is increased.

<Means for Solving the Problems> The present invention is a construction method for attaching a flat metal upper piece attached to a lower wall panel and a lower piece attached to a lower wall panel to a base metal attached to a steel beam. In the first step, first, the upper metal piece attached to the lower wall panel is brought into contact with the vertical metal piece of the side surface substantially L-shaped attached to the steel beam. Next, the standing piece and the mounting piece are sandwiched in the gap provided in the lower metal member to temporarily fix the lower wall panel. Then, while suspending the upper layer wall panel to which the mounting bolt is loosely mounted in advance, the bolt shaft of the mounting bolt is engaged with the bolt shaft insertion groove provided in the back plate of the lower metal member. Then, while suspending the wall panel, the mounting bolts are fitted into the bolt mounting holes and positioned with respect to the lower hardware.

Finally, the lower bolt is mounted on the upper wall panel by tightly connecting the mounting bolt and the mounting bolts fitted into the other bolt mounting holes.

<Operation> The vertical piece of the base metal piece attached to the steel beam and the flat upper metal piece attached to the wall panel of the lower layer are sandwiched in the gap of the lower metal piece, and the back of the lower metal piece is attached to the upper wall panel. Since the face plate is bolted, the connection between the upper part of the lower wall panel and the lower part of the upper wall panel and the attachment of the upper wall panel to the building frame (steel beam) are almost completed at this point. The holding state of the upper metal object can follow the so-called in-plane displacement without restricting the upper part of the lower wall panel from swinging in the in-plane direction. On the other hand, when mounting the lower-layer metal panel on the upper-layer wall panel, the upper-layer wall panel is hung so that the bolt shafts of the mounting bolts previously mounted on the upper-layer wall panel engage with the bolt shaft insertion grooves of the lower-layer metal panel. In this case, the mounting bolt is fitted into the bolt mounting hole by using the bolt shaft insertion groove as a guide. By tightening this mounting bolt and the mounting bolts inserted in the other mounting holes, the upper wall panel is completely mounted on the frame. In this way, the mounting work can easily attach the upper wall panel and the lower wall panel.

<Example> Next, a wall panel mounting construction of the present invention will be described with reference to the drawings. Prior to the description of the construction, the structure of each mounting hardware and the like will be described.

FIG. 1 is a perspective view showing an attachment metal piece used in the construction method of the present application, that is, a lower metal piece 1 attached to a lower wall panel. FIG. 2 is a sectional view taken along the line AA in FIG.

This lower hardware 1 includes a back plate 11 and both side portions 11a, 11 of the back plate 11.
It is formed in a generally U-shaped cross section by the sleeve plates 12 and 13 projecting substantially perpendicularly from b. Further, the sleeve plates 12 and 13 are formed with substantially vertically elongated notch grooves 14 and 15 by opening the lower sides 12a and 13a thereof. Further, a support plate 16 is installed between the sleeve plates 12 and 13. The support plate 16 has a substantially L-shaped side surface by a vertical piece 16a and a horizontal piece 16b. Moreover, the vertical piece 16a includes side edges 14a of the cutout grooves 14 and 15 facing the rear plate 11,
They are installed in the state of being respectively arranged in 15a. Therefore, a gap 17 is formed between the cutout grooves 14 and 15 between the inner surface 11c of the back plate and the outer surface 16c of the vertical piece. Further, the horizontal piece 16 of the support plate 16
A screw portion 18 of the level adjusting bolt is provided at the center of b directly or by attaching a nut. A level adjusting bolt (not shown) is screwed into this screwing portion 18, and its tip is pressed against a mounting piece of a base metal piece described later to adjust the height position of the upper wall panel through the lower metal piece 1. A plurality of, for example, two bolt mounting holes 11d and 11e are formed in the rear plate 11 in a lateral loose shape. That is, both bolt mounting holes 11d,
The lower bolt 1 is mounted by inserting a mounting bolt into 11e and screwing the mounting bolt into the upper wall panel.

A bolt shaft insertion groove 19 is formed in at least one of the bolt mounting holes 11d and 11e by opening the upper end 11f of the back plate 11.

The width of the lower metal piece 1 is narrower than the standing piece of the base metal piece 2 between the cutout grooves and larger than the plate width of the upper metal piece 3. That is, the upper metal fitting 3 is the narrowest and the base metal fitting 2 is the widest.

The mounting construction method of the present invention using the lower hardware 1 having the above configuration will be described.

As shown in FIG. 3, first, the base metal piece 2 having a substantially L-shaped side surface is fixed to the flange of the steel beam H by the mounting piece 21 and the standing piece 22. Then, the flat plate-shaped upper metal 3 attached to the lower wall panel P ₁ is arranged such that the attachment piece 3a thereof abuts the standing piece 22.

Next, the lower metal piece 1 is held in the gap 17 with the standing piece 22 and the mounting piece 3a being substantially overlapped with each other. This allows the underlying wall panel
P ₁ will be temporarily fixed to the steel beam H via the base metal 2. And with respect to the upper wall panel P ₂ which drop-off suspended from above, the bolt mounting holes 11d, screwed mounting bolts V that fitted to 11e.

Meanwhile To attach the lower hardware 1 to the upper wall panel P _2, as shown in FIG. 4, previously mounting bolts V into the upper layer of the wall panel P ₂
Is loosened somewhat (the bolt shaft Va is made longer than the thickness of the back plate 11) and screwed. Then, when the wall panel P ₂ is suspended, the bolt shaft Va of the mounting bolt V is engaged with the bolt shaft insertion groove 19. Then, when the wall panel P ₂ is suspended, the mounting bolt V is inserted into the bolt mounting hole 11e as it is. Then another bolt mounting holes 11d fitted mounting bolts V into cuttings, wall panels P ₂ bolt holes (not shown)
Screw the mounting bolt into the inside. And both mounting bolts V,
Tighten V. As a result, the lower hardware 1 is attached to the upper wall panel P ₂ while holding the base metal 2 and the upper metal 3 between them.

As another embodiment of the lower hardware 1 used in the construction method, the one shown in FIG. 6 is used. This lower hardware 1 '
The vertical piece 16a of the support plate 16 is provided with screwing portions 4a and 4b of a holding bolt (see FIG. 7). The threaded portions 4a, 4b are nuts n, n aligned with the through holes 16c, 16d of the vertical piece 16a and fixed by means such as spot welding. The lower hardware 1 '
As shown in FIG. 7, the holding bolts 5 are attached to the threaded portions 4a and 4b.
Are screwed together and the tip 5a of the bolt shaft is pressed against the standing piece 22 of the base metal piece 2. That is, as the holding bolt 5 presses against the standing piece 22, the back plate 11 (inner surface 11c) and the standing piece 22 are sandwiched,
As a result, the upper hardware 3 is securely held between the back plate 11 and the standing piece 22. After these installations are completed, the required parts such as the contact parts of the lower metal part and the base metal part are welded to join them together.

<Effects of the Invention> As described above, according to the mounting construction method of the present invention, particularly when constructing the upper wall panel, the mounting work of the lower metal piece on the wall panel becomes extremely easy, and the mounting construction time and cost are further reduced. Work safety is secured. Further, structurally, the height direction adjustment of the upper wall panel can be easily performed by using the level adjusting bolt. Furthermore, since the upper metal piece is sandwiched between the lower metal piece and the base metal piece, the upper metal piece can be slid in the in-plane direction, and thus can sufficiently perform the following function with respect to wind pressure and interlayer displacement.
