Description

[0001]
[Field of the Invention]
The present invention relates to a mounting structure of a base steel material for mounting an ALC panel when an outer wall, a roof, a floor, etc. of a building is configured with an ALC panel, and in particular, a base steel material for mounting an ALC panel having a thickness exceeding 1.6 mm is a steel frame. It is related with the attachment structure in the case of fixing to a pillar or beam.
[0002]
[Prior art]
Conventionally, when an ALC panel is attached to a pillar or beam of a steel frame of a building to form an outer wall, roof, floor, etc., the ALC panel is not directly attached to the steel frame (column or beam) of a building. In order to easily and accurately attach the ALC panel, it is common to attach a base steel material for ALC panel mounting to a steel frame in advance and attach the ALC panel to the base steel material with a predetermined mounting bracket or the like.
[0003]
Normally, a long angle steel is used for the ALC panel mounting base steel, and the mounting structure of this steel frame is shown in FIG. 5, and the ALC panel mounting base steel is attached to the flange 2-1 of the steel frame 2 as shown in FIG. 1 is superposed and the front side and the back side of the overlapped portion are welded at a length of 50 mm and 30 mm at intervals of 600 mm, respectively, and as shown in FIG. 6, the flange 2-1 of the steel frame 2 and the ALC panel There is a structure in which the mounting base steel material 1 is fixed by bolts 5 and nuts 6. Further, as shown in FIGS. 7 (A) and 7 (B), a pilot hole 1-1 penetrating to the back surface is provided at a predetermined position of the base steel material 1, and the base steel material 1 is attached to the steel frame 2 with a launching rod 3 There is a structure (A) and a structure (B) in which a base steel material 1 processed to be thinly thin so as not to disturb the hammering is attached to the steel frame 2 by a firing hammer 3 (see Patent Document 1).

[Problems to be solved by the invention]
However, the conventional mounting structure of the base steel material for mounting an ALC panel has the following problems.
That is, in the mounting structure by welding shown in FIG. 5, (1) the equipment to be used such as a resistor is large, and it takes a lot of time and labor to prepare for the work, (2) the quality tends to vary depending on the skill, (3) ▼ Slag removal and rust prevention treatment is required, ▲ 4 ▼ Power is required and exhaust gas is generated from the generator, ▲ 5 ▼ Cannot be constructed in rainy weather, ▲ 6 ▼ Spark curing is necessary, ▲ 7 ▼ There are many problems such as poor construction efficiency and 8 high construction costs.
[0006]
In addition, the bolt / nut mounting structure shown in FIG. 6 requires that the steel frame and the base steel material be prefabricated in advance for bolt penetration, and preparation work such as detailed meetings in advance is separately performed. There is a problem that it is difficult to standardize under the condition that the shape and dimensions differ from building to building, and the cost is high.
[0007]
7A and 7B, the mounting structure using the launching rod 3 has a thickness that does not hinder the hammering or the pilot hole 1-1 that penetrates the base steel material 1 to the back surface at a predetermined position. It is necessary to carry out processing such as thinning in advance at the factory, and in this case as well as the mounting structure with bolts and nuts, it is difficult to standardize under conditions with different shapes and dimensions for each building, so the cost is high There is a problem of sticking.
[0008]
On the other hand, in the case of a structure in which a base steel material with a thickness of more than 1.6 mm is attached to a steel frame by a conventional launching rod without providing a pilot hole or processing a thin thickness, In FIG. 8, since the steel material swells to the outside, a gap 7 is generated between the base steel material 1 and the steel frame 2 as shown in FIG.
[0009]
The present invention has been made to solve such problems of the prior art, and in particular, a base steel material for mounting a thick ALC panel having a thickness exceeding 1.6 mm can be simply and quickly, and efficiently. It is intended to propose a mounting structure for an ALC panel mounting base steel that can be mounted on a steel frame or beam at low cost.
[0010]
[Means for Solving the Problems]
A mounting structure for an ALC panel mounting base steel according to the present invention is a mounting structure for fixing an ALC panel mounting base steel having a thickness exceeding 1.6 mm to a column or beam of a steel frame, and for mounting the ALC panel. The base steel for mounting the ALC panel without gaps in the base steel and the steel frame column or beam without using a pilot hole or machining, with a metal or hard resin disk-shaped stopper member on the shaft. It is characterized by being configured by fixing.
[0011]
In the present invention, the launching rod having a disk-shaped stopper member in the shaft portion is used because the disk-shaped stopper member is used for the hammering even when the thickness of the ALC panel mounting base steel material exceeds 1.6 mm. This is to suppress the bulge around the base steel material and the steel frame body from rebounding due to impact. The disc-shaped stopper member is fitted into the substantially middle portion of the shaft portion, and a plurality of locations are temporarily fixed to the shaft portion by welding or the like, or are fitted and fixed slightly tightly. The thickness and outer diameter of the disc-shaped stopper member are preferably 1 to 3 mm and 10 to 30 mm, respectively. That is, if the thickness is less than 1 mm, the strength is weak and does not function as a stopper, while the thickness exceeding 3 mm is not necessary for strength. Further, when the outer diameter is less than 10 mm, the stopper function is not achieved, and on the other hand, the size exceeding 30 mm is not practical. The material is not particularly limited, but may be any material as long as it is not damaged by impact at the time of striking, for example, a metal such as stainless steel, iron or aluminum, or a hard resin such as reinforced plastic. Furthermore, it is preferable to use a galvanized kite in consideration of corrosion resistance.

The disk-like stopper member 3-3 can have a spring property at the time of striking by having a curved shape so as to be convex toward the head side.
[0014]
Next, a mounting structure example of the base steel material for mounting the ALC panel using the launching rod 3 will be described with reference to FIGS.
The first embodiment shown in FIG. 2 is an example of a mounting structure of a base steel material for mounting an ALC panel when a vertical outer wall is configured with an ALC panel. First, the thickness is set on the beam flange 2-1 of the steel frame 2. A long ALC panel mounting base steel material 1 made of angle steel exceeding 1.6 mm is temporarily fixed using a tool (not shown). At this time, the position adjustment of the ALC panel mounting base steel material 1 is completed so as to be a fixed distance from the finished position of the outer wall surface of the ALC panel. Subsequently, the launcher with a disk-shaped stopper member shown in FIG. 1 (for example, head diameter 10 mm, shaft diameter 4.5 mm, shaft length 22 mm) 3 is set in a dedicated hammer (not shown), This launching rod 3 is driven from the side of the ALC panel mounting base steel 1 into the center of the width of the overlapping ALC panel mounting base steel 1 and beam flange 2-1 (FIG. 2A). At this time, the shaft portion 3-1 of the launching rod 3 passes through the base steel material 1 and the flange 2-1, and at the same time, the disc-like stopper member 3-3 moves to the head 3-2 side and moves to the head 3-2. By being pressed down and used as a spacer, the base steel material 1 and the bulge around the beam flange 2-1 are restrained from rebounding due to impact at the time of striking. Therefore, as shown in FIG. The beam flange 2-1 is fixed without a gap.

[0015]
The second embodiment shown in FIG. 3 and FIG. 4 is an example of the mounting structure of the base steel material for mounting the ALC panel when the lateral wall is configured with the ALC panel. First, the other beam flange 2-1 of the steel frame 2 is shown. A base steel material (hereinafter referred to as “primary fastener”) 11 for mounting a primary ALC panel having a short length (for example, length of 100 mm) made of angle steel having the same thickness as above as 1.6 mm on both sides of the lower surface is referred to as a tool. Temporarily fix using. At this time, considering the attachment of the secondary base steel material (long) 12 for attaching the ALC panel, the position adjustment of the primary fastener 11 in the left-right direction (panel longitudinal direction) is completed. Then, similarly to the above, the launching rod 3 with a disk-like stopper member is set in a dedicated hammering machine (not shown), and the firing hammer 3 is placed at the center of the width of the overlapped primary fastener 11 and flange 2-1. Driving is performed from the primary fastener 11 side (FIG. 3A). At this time, similarly to the above, the shaft portion 3-1 of the launching rod 3 passes through the primary fastener 11 and the flange 2-1, and at the same time, due to the action of the disk-like stopper member 3-3, the primary portion from the rebound due to the impact at the time of hammering. Since the swell around the flanges of the fastener 11 and the beam flange 2-1 is suppressed, the primary fastener 11 and the beam flange 2-1 are fixed without a gap as shown in FIG. In this case, the primary fastener 11 is fastened at two locations to prevent rotation. Then, this operation is performed at a desired interval (for example, 900 mm) in the length direction of the base steel material 1 to complete the attachment of the primary fastener 11.
[0016]
Next, as shown in FIG. 4, a secondary base steel material 12 for attaching an elongated ALC panel made of angle steel having a thickness exceeding 1.6 mm is attached to the primary fastener 11 previously attached to the tool (see FIG. 2). In a state of being temporarily fixed using (not shown), the firing hammer 3 is driven from the secondary base steel material 12 side by the same method as described above (FIG. 4A). At this time, the shaft portion 3-1 of the launching rod 3 penetrates the secondary base steel material 12 and the primary fastener 11, and at the same time, due to the action of the disc-like stopper member 3-3, the secondary base is prevented from being rebounded by the impact at the time of driving. Since the swell of the steel material 12 and the primary fastener 11 around the heel is suppressed, the primary fastener 11 and the secondary base steel material 12 are fixed without a gap as shown in FIG. In this case, it will be fixed one place at a time. And this operation | work is performed for every primary fastener 11 in the length direction of the secondary base steel material 12, and the attachment of the base steel material for ALC panel attachment is completed.
After that, as before, the ALC panel is mounted on the base steel material 12 one by one using the specified mounting bracket as before, sealing work between the ALC panels, finishing work on the surface of the ALC panel, and exterior wall work. Complete.
