Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for mounting a concrete panel in which a mounting member such as an insert nut is embedded to a pillar of a frame.

[0002]

[Prior art]

 For example, as a mounting structure of a panel in which a lightweight cellular concrete panel (hereinafter referred to as “ALC panel”) is mounted on a pillar of a skeleton to form an outer wall, a structure shown in FIG.

This is a configuration in which a ruler angle 2 is vertically welded to a column 1 and welded, and a horizontally long ALC panel 3 is attached thereto. An insert nut 4 is embedded in advance at a predetermined position near each end of each ALC panel 3, and a mounting plate 5 called an "inner plate" is fixed to the insert nut 4 with a bolt 6, and the mounting plate 5 is fixed with a ruler. It is designed to be welded to glue 2.

[0004]

[Problems to be solved by the device]

 By the way, the thickness of the pillar 1 varies variously depending on the design specifications of the building. However, in the above configuration, since the ruler angle 2 is directly welded to the column 1, the dimension between the ruler angles 2 also differs depending on the thickness dimension of the column 1. If the dimensions are different, the dimensions of the mounting plates 5 are also different, and the dimensions of the insert nuts 4 embedded in the ALC panel 3 are also different. For this reason, if the conventional ALC panel mounting structure is adopted, it is necessary to change the embedding position of the insert nut 4 into the ALC panel 3 according to the design specifications of the building. Accordingly, there is a problem that various ALC panels 3 must be manufactured.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a concrete panel mounting structure capable of mounting a standardized concrete panel even if the column has different thickness dimensions. is there.

[0006]

[Means for Solving the Problems]

 In the mounting structure of the present invention, an auxiliary metal object is welded and fixed to the pillar of the skeleton, a ruler angle is welded to the welding surface portion of the auxiliary metal object, and the concrete panel is ruled by a mounting member embedded in the concrete panel. It is fixed to the angle. In this case, the welding surface portions formed on the auxiliary metal piece are opposed to each other with a predetermined distance.

[0007]

[Action]

 Two ruler angles extend vertically and are welded to the welded surface of the auxiliary metal object fixed to the pillar, and the concrete panel is fixed to the ruler angle via a mounting member. Here, since the welding surface portions of the auxiliary metal are opposed to each other with a predetermined spacing dimension, the dimension between the two ruler angles welded here is always irrespective of the column thickness dimension. Be constant. Therefore, the position of the mounting member embedded in the concrete panel may always be constant and can be standardized.

[0008]

[Effect of device]

 As described above, according to the concrete panel mounting structure of the present invention, the position of the mounting member of the concrete panel may be constant regardless of the size of the column, so that the specifications of the concrete panel can be standardized. Produce an effect.

【Example】

 An embodiment in which the present invention is applied to a lateral wall construction method when an ALC panel is constructed as an outer wall of a building will be described with reference to FIGS. 1 to 4.

FIG. 1 shows a state in which the ALC panel 11 is attached to the body as seen from the outside of the building. In the case of this embodiment, square steel is used as the pillar 12 of the skeleton, and a plurality of auxiliary hardware 13 are intermittently fixed thereto. The fixed interval is, for example, 600 mm to 900 mm when the width of the ALC panel 11 is 600 mm.

As shown in FIG. 4, the auxiliary metal 13 is made of so-called hat-shaped steel having base portions 13a extending in opposite directions on the opening side of the U-shaped cross section, and has a predetermined distance D (this embodiment). Has a pair of welding surface portions 13b facing each other at about 50 mm), and the length dimension is about 100 mm in this embodiment. The bottom portion 13a is welded to the surface of the pillar 12 on the outer wall side of the building, and is fixed in a form that extends vertically along the pillar 12.

A ruler angle 14 made of L-shaped steel is fixed to each of the welding surface portions 13b of the auxiliary metal piece 13 in a form of extending vertically by welding.

On the other hand, the ALC panel 11 has a standardized specification, and as shown in FIG. 3, two insert nuts corresponding to mounting members are provided inwardly displaced from both ends in the longitudinal direction by a predetermined dimension X. 15 are buried respectively. These insert nuts 15 are embedded at the time of manufacturing the ALC panel 11. For example, the insert nuts 15 are integrated with a reinforcing bar (not shown) inside and are housed in the molding die. It is manufactured by pouring and solidifying foamy cement slurry.

A bolt 16 is screwed into each of the insert nuts 15, and two stepped mounting plates 17 called “inner plates” are fixed to both ends of the ALC panel 11 by this. As shown in FIG. 2, these stepped mounting plates 17 are welded together with the tip end of the ruler angle 14 sandwiched between the ruler angle 14 and the ALC panel 11. As a result, it is attached to the pillar 12.

The stepped mounting plate 17 is fixed by a bolt 16 via a square washer 18, and the bolt insertion hole 17a formed in the stepped mounting plate 17 is vertically long and Even if interlayer displacement occurs in the body due to strong wind or strong wind, the ALC panel 11 is prevented from being subjected to excessive force.

Next, a work procedure for fixing the ALC panel 11 to the body with the above configuration will be described.

First, the auxiliary metal fitting 13 is intermittently welded and fixed to the pillar 12 of the skeleton. Next, two ruler angles 14 are welded to both welding surface portions 13b, 13b of each auxiliary metal 13 so as not to be tilted by using a downward swing or the like. On the other hand, bolts 16 are screwed into the insert nuts 15 near the both ends of the ALC panel 11, and two stepped mounting plates 17 are loosely attached. Then, the ALC panel 11 is hoisted by a crane or the like, the bolts 16 are fastened to the pillars 12, and the stepped mounting plates 17 are welded to the ruler angle 14 to complete the mounting of the ALC panel 11.

In the present embodiment described above, the dimension D between the two welding surface portions 13b of the auxiliary metal 13 is a standardized constant value, so the distance between the two ruler angles 14 welded here is also the column 12 It is a constant value regardless of the thickness of. Therefore, the embedded positions of the two insert nuts 15 provided on the ALC panel 11 can be fixed regardless of the thickness of the column 12.

For example, FIG. 5 shows a state where the ALC panel 11 is attached to the pillar 20 thicker than that shown in FIG. 2, and it is possible to use the ALC panel 11 having the same specifications as in the case of FIG. It's clear.

This means that ALC panels of the same specifications can always be used even if there are circumstances in which the thickness of the pillars differs according to the design specifications of the building, and that many types of ALC panels can be used. This means that there is no need to manufacture and put into inventory. As a result, the specifications of the ALC panel can be standardized and mass-produced, and the manufacturing cost can be reduced and product management can be rationalized accordingly.

The present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented by being modified as follows, for example.

(1) In the above-described embodiment, the configuration in which the square steel is used as the column 12 is shown, but the present invention is not limited to this, and the same can be applied to the case where the H-section steel is used as the column. For example, the structure is as shown in FIG. 6, and the auxiliary metal fitting 13 may be welded to one surface of the H-shaped steel 21 and the ruler angle 14 may be welded to the welding surface portion 13b. Since the other points are the same as those in the above-mentioned embodiment, the same parts are designated by the same reference numerals and the description thereof will be omitted.

(2) In the above embodiment, an example was shown in which the insert nut 15 was embedded in the ALC panel 11 as a mounting member, but the present invention is not limited to this, and an anchor bolt is embedded as a mounting member (not shown). May be.

Besides, the present invention can be applied to not only the ALC panel but also a mounting structure of a precast concrete panel, and various modifications can be made without departing from the scope of the invention.
