[0001]

[Industrial applications]

 The present invention relates to a method for horizontally stacking aerated concrete wall panels.

[0002]

[Prior art]

 Conventionally, as a method of horizontally stacking aerated concrete wall panels represented by lightweight aerated concrete (ALC), a plurality of aerated concrete wall panels in which insert metal fittings are embedded are laid horizontally to stand up in multiple rows. There is a construction method in which the walls of the building are constructed by stacking and fixing the adjacent ends of the horizontally arranged wall panels among the wall panels to the pillars through the mounting brackets. -23517 publication).

[0003]

[Problems to be solved by the device]

 In this construction method, the receiving angle that receives the weight of the plurality of panels is fixed to the column, but there is a problem that the portion of the panel that directly contacts the receiving angle is easily damaged. Therefore, the present inventor has made earnest studies on the structure of the panel mounting hardware that can avoid this problem, and found the fact that the receiving angle does not have to be used if a specific hardware is used in combination, and the present invention has been completed. Therefore, an object of the present invention is to propose a horizontal stacking construction method for wall panels that does not use a receiving angle.

[0005]

[Action]

 First, when a plurality of air bubble concrete panels in which insert fittings consisting of long nuts are embedded are built adjacent to each other, the third side is placed at the position where the short-side end faces come to the center in the width direction of the column. Weld and fix the hardware. The second metal piece of the first metal piece and the second metal piece that has been integrated in advance is connected to the third metal piece via a connecting pin. Then, the bolt is screwed into the insert metal fitting of the panel, and the bolt is locked to the locking portion of the first metal object. Then, the locking portion itself acts as a conventional receiving angle, and the panel is locked to the pillar. Therefore, the panel is fixed to the column by the cooperation of the bolt, the first, second and third metal fittings, and the pin.

[0006]

【Example】

 Next, the present invention which is embodied in a mode in which ALC panels are fixed to a rectangular column and horizontally stacked will be described with reference to FIG. First, in this embodiment, a plurality of air bubble concrete panels 1 are horizontally stacked so as to stand up with their in-plane directions facing upward and downward, and the wall panels are adjacent to these horizontally stacked panels 1. 2 are stacked in the same way. In this way, the outer wall of the building is formed by a plurality of rows of horizontally stacked panels. Then, among the end portions on the short side of the panels 1 and 2, adjacent end portions 1 a and 2 b are fixed to the column 4 via a set of mounting brackets 30. In addition, insert fittings (not shown) made of long nuts are embedded in predetermined positions of the wall panels 1 and 2.

The metal fitting 30 basically has bolts 35 a and 35 b screwed into the insert metal fitting, a plate-shaped first metal fitting 31, and a first metal fitting 31 extending from the first metal fitting 31 in a direction orthogonal to the first metal fitting 31. It is composed of a combination of two metal fittings 32, a third metal fitting 33 fixed to the pillar by welding so as to stick to the pillar, and connecting pins 34a, 34b for connecting the second metal fitting 32 and the third metal fitting 33. Has been done.

The first metal fitting 31 has two locking portions 31a and 31b, which are notched upward to lock the head portions of the bolts 35a and 35b near both ends thereof. ing. The second metal fitting 32 is composed of two projecting pieces extending from the first metal fitting 31 in a direction orthogonal to the first metal fitting 31, and elongated holes 32a and 32b which are long in the horizontal direction are provided through them. In this embodiment, the second metal fitting 32 is made of a metal piece having a U-shaped cross section obtained by bending both end sides of one plate-shaped body in the same direction, and the elongated hole 32 is formed on the bent piece. a and 32b are provided. The main plate portion that has not been bent is welded and fixed to approximately the center of the first metal fitting 31.

Similar to the second metal fitting 32, the third metal fitting 33 is a metal member having a U-shaped cross section formed by bending both end sides of one plate-shaped body. The bent piece portions 33a, 33b formed by bending are provided with long holes 33e (33f not shown) which are long in the up-down direction, and the main plate portion 33d which is not bent is provided with the third metal piece 33. A welding hole 33o for welding to the column 4 is provided.

When the two panels 1 and 2 adjacent to each other are fixed to the pillar 4 via the mounting hardware 30, the construction is performed in the following procedure. First, the panels 1 and 2 to be walls are temporarily arranged on a plurality of pillars 4 which are one of the structural frames of the building, and the ends 1a and 2b adjacent to each other are located substantially at the center of one pillar 4. To do so.

In this case, the openings of the insert fittings of both the panels 1 and 2 are exposed in advance, the pressing plates 36a and 36b having the long holes 36c in the horizontal direction, and the washers 37a and 37b are provided on the pressing plates 36a and 36b. After the bolts 35a and 35b are respectively applied to the openings, the bolts 35a and 35b are screwed into the insert metal fittings so that their heads protrude slightly longer than the thickness of the first metal fitting 31. In addition, the second metal fitting 32 is assembled to the first metal fitting 31 by welding.

Next, the inner peripheral side of the welding hole 33 o of the third metal piece 33 is welded to the column 4 to fix the third metal piece to the column 4. Then, the elongated holes 32a, 32b of the second metal piece 32 and the elongated holes 33e, 33f of the third metal piece 33 are made to correspond to each other by using the connecting pins 34a, 35b, the washers 37a, 37b and the nuts 38a, 38b. Connect the hardware 32, 33. Then, the third metal piece 33, the second metal piece 32, and the first metal piece 31 are fixed to the pillar 4.

In this way, after the head portions of the bolts 35a and 35b protruding from the panels 1 and 2 are locked to the locking portions 31a and 31b of the first metal fitting 31 fixed to the pillar 4, When the bolts are tightened, the ends of the panels 1 and 2 are fixed to the pillar 4. By fixing the panels 1 and 2 at the other end side in the above manner, and by stacking other panels on the upper side of these panels, they can be built as a wall of a building.

In this embodiment, unlike the prior art, a receiving angle for receiving the own weight of a plurality of panels is unnecessary, and as a result, the own weight of the panel is concentrated on the own weight receiver, and the lower end thereof is easily damaged. The problem to say is solved. Also, since the panel itself has the function of a beam, the ruler angle is no longer required as in the prior art, and the building construction efficiency can be improved.

The present invention can be carried out by changing the mode of the embodiment within the scope of not significantly impairing the effect of the invention by following the fundamental technical idea. For example, as shown in FIG. 2, a part of the first metal fitting 31 is bent to integrally form the second metal fitting 32 there, and the third metal fitting 33 is formed in an inverted L-shape in longitudinal section so as to correspond to the metal fitting. You can also do it.

[Effect of device]

 As described above in detail, the present invention enables the construction of a building that does not require the weight receiving angle of the panel and the ruler angle, and exhibits an excellent effect that the construction efficiency can be greatly improved.
