Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ALC (lightweight cellular concrete) wall panel mounting structure.

[0002]

2. Description of the Related Art Conventionally, an ALC wall panel in a structure is attached by a structure as shown in FIGS. On the upper surface of a steel beam 100 as one of the structural skeletons, an L-shaped angle 101 as one of base steel materials for adjusting the ingress and egress of the ALC wall panel 110 is placed on its horizontal piece 102. The ingress and egress (front-back position) of the ALC wall panel 110 is adjusted by shifting the mounting position of the L-shaped angle 101 back and forth. The outer dimensions of the L-shaped angle 101 are, for example, about 65 mm × 65 mm, and the thickness is about 6 mm.

A fillet weld a is formed between the rear edge of the horizontal piece 102 and the upper surface of the steel beam 100 by downward welding.
The L-shaped angle 101 is welded and fixed to the steel beam 100 by forming a fillet weld b between the lower surface of the horizontal piece 102 and the front edge of the steel beam 100 by upward welding. The reason why the fillet welds a and b are formed at the two front and rear positions in this way is that the L-shaped angle 101 is not disengaged even if a downward or upward force is applied to the L-shaped angle 101. It is. On the front surface of the vertical piece 103 of the L-shaped angle 101, a vertical cover plate 104 as one of mounting hardware is fixed by welding, and an upper layer ALC is attached to the vertical cover plate 104.
The wall panel 110 is placed.

Then, in the wet construction method (insertion stitch construction method), joint recesses 111 on the side end surfaces of the ALC wall panel 110 are used.
, A joint reinforcing bar 105 passed through a vertical cover plate 104 is inserted, and a mortar 106 is filled.
Attach the wall panel 110. This ALC wall panel 11
When 0 is particularly long, a progress plate (not shown) as one of the mounting hardware is hooked on the vertical piece 103, and the ALC wall panel 110 is mounted on the progress plate with bolts.

In the dry construction method (locking construction method), a sander plate (not shown) as one of mounting hardware is hooked on the vertical piece 103, and the sander plate is mounted on the sander plate by AL.
Attach the C wall panel 110 with bolts.

That is, in both the wet and dry construction methods, the vertical piece 103 functions as a ruler surface that regulates the ingress and egress of the ALC wall panel 110, and the mounting hardware (vertical plate 104, inazuma plate, sander plate, etc.). Acts as a fixed surface for fixing

[0007]

As described above, the conventional A
In the mounting structure of the LC wall panel, an L-shaped angle 101 has been exclusively used as a base steel material. This is because it has been considered that a vertical piece having a certain height is indispensable in order to adjust the ingress and egress of the ALC wall panel 110 and secure wind resistance, and the L-shaped angle 101 increases rigidity. It seems that it is easy to obtain.

However, the conventional ALC wall panel mounting structure has the following problems. The L-shaped angle 101 includes both horizontal and vertical plates 10.
2,103 and generally having a length of about 5 to 6 m, it was considerably heavy and was disadvantageous in workability, handling, transportability and the like. The material cost of steel also increased. The L-shaped angle 101 connects the vertical piece 103 to the steel beam 10
0, the steel beams 10 protrude forward from the front end.
Since it is placed on the zero, the center of gravity may protrude from the steel beam 100. Therefore, the L-shaped angle 1 in this state
When welding 01 to the steel beam 100 by welding, it was necessary to perform welding while paying attention to stability so that the L-shaped angle 101 did not fall off the upper surface of the steel beam 100. The fillet weld a can be formed by downward welding that is easy to work from inside the structure, but the fillet weld b must be formed by upward welding that is difficult to perform from a welding scaffold assembled outside the structure. was there. In addition, since upward welding easily causes welding defects, it has been difficult to secure welding strength.

[0009] It has been proposed that a mounting hardware is directly fixed to a steel beam without providing a base steel material such as an L-shaped angle and an ALC wall panel is mounted on the mounting hardware.
It was difficult to adjust the lateral position of the LC wall panel, and the workability was considerably poor.

[0010] An object of the present invention is to solve the above-mentioned problems and to provide an AL
By reducing the weight of the base steel material for adjusting the entry and exit of the C wall panel, the workability, handling, transportability, cost, etc. can be improved, and the stability of the base steel material when placed on the structural frame is improved. An object of the present invention is to provide an ALC wall panel mounting structure capable of performing the welding fixing operation easily and safely.

[0011]

In order to achieve the above object, an ALC wall panel mounting structure according to the present invention comprises a flat flat bar as a base steel material for adjusting the entrance and exit of the ALC wall panel on a structural frame.

Further, the application of this mounting structure is not limited to a specific construction method, and can be applied to, for example, a rocking construction method (dry construction method) and an insertion reinforcing construction method (joint reinforcing bar + mortar).

The mode of welding and fixing the flat bar to the structural frame is not particularly limited, but it is preferable to provide at least one notch in the flat bar and to perform downward welding between the cut surface of the notch and the structural frame. .

The notch includes a U-shaped or V-shaped external notch cut out from the trailing edge of the flat bar, a circular hole, an oval hole cut out so as to penetrate an intermediate portion of the flat bar, and the like. Examples include a square hole, a triangular hole, and an internal notch such as a short slit. The internal notch is preferable in that the strength of the flat bar is less reduced and the flat bar can be prevented from bending.

The following two types of embodiments (1) and (2) can be exemplified as the mounting hardware.

The mounting hardware is constituted by three pieces of an L-shaped hardware integrally including a fixed plate and an upper panel mounting plate, a self-weight receiving plate, and a lower panel mounting plate. And fix it by welding. The mounting hardware is composed of two pieces: an L-shaped hardware integrally including a fixing plate and an upper panel mounting plate, and an L-shaped hardware integrally including a self-weight receiving plate and a lower panel mounting plate. The two pieces are welded together or fixed to the flat bar. The mounting hardware is constituted by one piece integrally including the fixing plate, the upper panel mounting plate, the weight receiving plate, and the lower panel mounting plate.

(2) A fixing plate for fixing the mounting hardware to the flat bar, an upper panel mounting plate for mounting the upper ALC wall panel with bolts, and a lower ALC

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show A of the first embodiment.
Fig. 3 shows a mounting structure of an LC wall panel. ALC wall panels 21 and 2 are provided on the upper surface of the steel beam 1 as one of the structural frames.
A flat bar 2 having a flat plate shape as a base steel material for adjusting the ingress and egress of the base 2 is placed, and its front and rear positions are adjusted and fixed by welding. More specifically, a plurality of oblong internal cutouts 3 are formed at predetermined intervals in the longitudinal direction of the flat bar 2 at substantially the center of the flat bar 2 in the front-rear width direction. A fillet weld A is formed by downward welding between the trailing edge of the flat bar 2 and the upper surface of the steel beam 1, and a plug weld B is formed between the cut surface of the internal notch 3 and the upper surface of the steel beam 1. Are formed by downward welding, so that the flat bar 2 is fixed to the steel beam 1. The front and rear width of the flat bar 2 is 65 mm to 75 mm, and the thickness is 6 to 8 mm.

Since the flat bar 2 does not have a vertical piece like the conventional L-shaped angle, even if the flat bar 2 is slightly thicker than the horizontal piece of the conventional L-shaped angle in order to secure the strength, the conventional L-shaped angle is used. It can be reduced in weight compared to a character angle. By reducing the weight of the base steel material, workability, handleability, transportability, and the like can be improved. Further, the cost can be reduced by saving the material of the base steel material.

The flat bar 2 is placed on the steel beam 1 in a state where at least half of its front-rear width is in contact with the upper surface of the steel beam 1 and its front end portion protrudes forward from the front end of the steel beam 1. As described above, since there is no vertical piece on the front end side, the center of gravity does not protrude from the steel beam 1. Therefore,
Flat bar 2 has high stability at the time of placing, and fillet weld A
And the welding work of the plug welding part B can be performed easily and safely. Further, the required welding strength can be reduced by an amount corresponding to the weight reduction of the base steel material itself, so that the welding portions of the fillet welded portion A and the plug welded portion B can be replaced with the conventional fillet welded portions a and fillet welded portions. b can be less than the welding location.

Since the internal notch 3 does not protrude forward of the front end of the steel beam 1 and is located near the front end of the upper surface of the steel beam 1, the plug welding portion B formed in the internal notch 3 is formed as shown in FIG. In addition, the fillet weld b in the conventional example of FIG. Therefore, the plug welded portion B functions as a conventional fillet welded portion b with respect to the force applied to the flat bar 2. And, unlike the fillet welded portion b by the conventional upward welding, the plug welded portion B can be formed by downward welding which is easy to work from the inside of the structure, so that there is no need to form a welding work scaffold outside the structure. It can be easily formed without a skilled worker.
