Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a structure for mounting an ALC panel to a beam in a dry method for fixing a C panel.

[0002]

2. Description of the Related Art As a method of fixing an ALC panel 1 (hereinafter referred to as a panel) for a floor or a roof to an upper surface of a steel beam 2, a reinforcing bar and mortar are conventionally used for joints.
A mounting structure (not shown) by a so-called wet method is common, but in recent years, for example, as shown in FIG. 5, a part of a steel beam using bolts 11, washers 12, and nuts 13 penetrating the panel 1 is used. Is carried out between the lightning plate 10 and the panel 1 to omit mortar filling, a so-called dry method.

[0003]

However, such a dry method requires a lot of man-hours for drilling and digging holes in the panel 1 for the bolts 11, repairing the holes, and uses a large number of mounting brackets. There is a problem that costs are high. In addition, as shown in FIG. 5, it was necessary to tighten the lightning plate 10 holding the steel beam 2 on the back side of the panel 1 while correcting the lightning plate 10 so that the lightning plate 10 would not be displaced by rotation. further,
As shown in FIG. 5, when the panel 1 is fixed by two points at both ends in the longitudinal direction, the panel 1 can be fixed even after the bolt 11 is fastened.
Since there is a possibility of rattling on the steel beam 2, a method of fixing the panel 1 at four points at both ends has been used. However, this method requires a large number of mounting steps and requires a large number of fittings and the like.

[0004] In addition, when the panel 1 is fixed on the steel beam 2, the space between the steel beams 2 is different from that of the plate-like floor base material, and the panel 1 is long and its width is compared. As shown in FIG. 6, when a large load is applied to the central portion of the panel 1, the panel 1 is often bent as shown in FIG. The lower surface 1a of the end of the panel 1 is liable to be rubbed or sometimes chipped when the lower surface 1a of the end of the panel 1 hits the edge of the upper surface of the steel beam 2, and the lower surface 1a of the end of the panel 1 is easily damaged.
There is a problem that dust of the panel 1 is scattered downward. In particular, the ALC panel 1 is porous and very fragile, unlike other materials. Therefore, when a floor panel or the like is fixed on the steel beam 2, there is a problem unique to the ALC panel.

[0005] It is an object of the present invention to solve the above problems and to improve the efficiency of installation of a panel on a steel beam by a dry method, to damage the lower surface of the panel and to disperse dust of the panel. It is an object of the present invention to provide a structure for mounting a panel without beams on a beam.

[0006]

According to the present invention, in order to solve the above-mentioned problems, an adhesive tape is interposed between a lower surface of a floor or roof panel and an upper surface of a steel beam, and the panel is connected to the steel beam. The structure to attach the panel fixed to the top to the beam was adopted.

The operation of the present invention will be described below. The use of adhesive tape to secure the panel on the steel beam eliminates the need for conventional panel drilling and digging work, as well as repairing the holes, improving the efficiency of construction. In addition, parts such as bolts and lightning plates can be eliminated. This shortens the construction period and reduces costs.

In addition to the fact that the panel is fixed on the steel beam by a surface instead of a point, the thickness of the adhesive tape adjusts the unevenness of the surface of the steel beam and buffers the dust or the like. The rattling during panel mounting has been reduced.

Further, since the adhesive tape is interposed as a cushioning material between the end of the steel beam and the lower surface of the panel, the lower surface of the panel end is likely to be generated when a load is applied to the center of the panel and the panel is bent. Chipping or rubbing can be prevented. As a result, damage to the lower surface of the panel and dust are less likely to occur. In addition, since the adhesive tape serves as a cushioning material between the steel beam and the panel, it also has an effect of making it difficult to transmit the impact generated on the floor to the downstairs.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS. As shown in FIG. 1, an attachment structure is provided in which the panel 1 is fixed on the steel beam 2 with an adhesive tape interposed between the lower surface of the floor or roof panel 1 and the upper surface of the steel beam 2. As the adhesive tape, a double-sided adhesive tape 3 or a planar fastener is preferable.
Above all, the double-sided adhesive tape 3 is more preferable in terms of mounting workability and cost.

As shown in FIG. 2, when the weight is applied to the central portion of the laid panel 1, the lower surface of the panel 1 does not interfere with the end of the steel beam 2 to disperse dust. It is desirable that the adhesive tape be attached to the end of the steel beam 2 as much as possible.

The thickness of the adhesive tape is 1.0 to 3 m.
m is preferred. If it is less than 1.0 mm, the effect as a cushioning material is reduced, and if it is more than 3 mm, it is not preferable in terms of cost and handling. The material of the double-sided pressure-sensitive adhesive tape includes polyester, polyethylene, acrylic and the like, but acrylic is preferable in terms of adhesive strength and durability, and width of 20 mm or more is preferable in terms of adhesive strength. The material of the sheet fastener is polyester, polyethylene, polypropylene, nylon or the like, but nylon is preferable in terms of durability, and the width is 20.
mm or more is preferable in terms of adhesive strength.

The joints on the steel beams 2 between the panels 1 are filled with a foamed polyethylene-based backup material 5 and an acrylic emulsion-based filler material 4.
Fillers 4 are filled between the joints in the long direction of the panel 1 as needed.

Next, a method of configuring the mounting structure of the present invention will be described. When the double-sided adhesive tape 3 is used, as shown in FIG.
Only after the double-sided adhesive tape 3 is adhered to the lower surface of the panel 1 on one side, the release paper 5 on the steel beam 2 side is peeled off, the panel 1 is inclined, and the new panel 1 is brought close to the panel 1 already laid. Lay it. According to this method, the front lower end of the new panel 1 can be easily laid and fixed at a predetermined position without adhering to the steel beam 2, which is preferable in construction.

After the double-sided adhesive tape 3 is attached to the back surface of the panel 1 with a setback portion a as described above, the panel 1 is attached to the panel 1 using an anchor (not shown) of a panel with a built-in anchor for lifting or a suction disk. It is also preferable to lay a new panel 1 close to the already laid panel 1 by lifting it horizontally.

Here, the set-back portion a is preferably provided about 10 mm in order to prevent the double-sided adhesive tape 3 attached to the panel 1 from adhering to the end of the double-sided adhesive tape 3 of another panel 1. . In addition, it is more preferable to stick the double-sided adhesive tape 3 to the panel 1 than to the steel beam 2 in advance from the viewpoint of work safety.

When a planar fastener is used, a planar fastener having both surfaces of a planar fastener having hook-shaped engaging elements and a planar fastener having loop-shaped engaging elements is engaged with the front end of the panel 1. Set back part a
After sticking only on one side, the panel 1 may be laid in the same manner as the double-sided adhesive tape 3. Further, in this planar fastener, a planar fastener having a hook-shaped engaging element and a loop-shaped engaging element are respectively pasted on the lower surface of the panel 1 or on the steel beam 2 to engage the panel 1 with the steel beam 2. May be.

Further, in a state where at least one surface is not adhered to the panel 1 or the steel beam 2, a double-sided adhesive tape provided with a peeling thread 5a as shown in FIG. After laying the panel 1 with a fastener interposed between the panel 1 and the steel beam 2, the peeling thread 5a
It is also desirable to fix the panel 1 and the steel beam 2 while pulling off the release paper 5 by pulling.

Hereinafter, the present invention will be described more specifically based on examples.

Embodiment 1 Thickness 100 mm, width 606 mm, length 20
