Description

[Detailed Description of the Invention] The present invention relates to a mounting bracket to be embedded inside a lightweight aerated concrete panel.

The purpose of this invention is to provide an embedded lightweight aerated concrete panel that can be attached to the reinforcing cage inside the lightweight aerated concrete panel with high positional accuracy, and that can increase the strength of the lightweight aerated concrete panel attached to the building frame. Our goal is to provide metal fittings.

Conventional lightweight aerated concrete panels (hereinafter referred to as
It's called an ALC panel. ) As for the structure of the embedded fitting for installation, for example, as shown in Fig. 4a, a long nut 5 is installed in advance.
A mounting bracket welded to the anchor iron plate 11 is welded to the reinforcing bar 4, and this is buried to form an ALC panel, or as shown in Fig. 4b, a channel steel 12 with a long nut 5 welded in advance is installed. There are some that are welded to reinforcing bars 4 and buried to form an ALC panel.
However, although these structures are extremely strong against external forces such as those shown by arrows M in Figures 4c and 4d, if there is a manufacturing error in the reinforcing bar cage, it may cause damage to the surface of the panel. This directly affects the positional accuracy of the metal fittings in the direction, and furthermore, in the example shown in FIG. 4b, the embedded metal fittings and the reinforcing bars may not come into good contact with each other, making welding impossible.

Therefore, with this invention, it is possible to increase the strength of ALC panel attachment to the building frame, and furthermore, the ALC panel can be attached to the building frame.
We have devised an embedded fitting for ALC panels that can be attached to the reinforcing cage inside the panel with high positional accuracy.

The configuration of the present invention will be explained with reference to FIG.

Straddling the two reinforcing bars 4, 4 arranged on both the upper and lower sides of the ALC panel 1, a plane part 7 perpendicular to the panel surface and a pair of flange planes bent at right angles from both side edges thereof. A cross-section channel steel embedded fitting consisting of portions 8, 8 has a square end face oriented in a direction perpendicular to the panel thickness direction, and the upper and lower surfaces of the flange flat portions 8, 8 are attached to reinforcing bars 4, 4, respectively. It is fixed by side welding. A long nut 5 for mounting is welded toward the upper surface of the square-shaped outer surface of the vertical plane portion 7 of the embedding fitting, and one end thereof is open to the upper surface of the ALC plate 1.

In addition, in this embodiment, the long nuts 6 for lifting the panel during construction are attached to the outer surface of the flat part 7.
It is welded with an opening facing the edge surface of the ALC panel 1. The embedded metal fittings and long nuts 5 for attachment are provided at required locations of the ALC panel 1, for example, at the four corners as shown in FIG. 1, and the ALC panel is constructed.

This ALC panel has the above-mentioned configuration, and when the bolt 9 is screwed into the long nut 5 and attached to the main body frame 10 as shown in FIG. 3, the external force acting on the long nut 5 through the bolt 9 is The embedded metal fitting 3 is composed of a vertical plane part 7 and two flange plane parts 8 orthogonal thereto.
It has high rigidity in the dimensional direction, and is fixed to the reinforcing bars 4, 4 arranged on both the upper and lower sides, so there is no risk of deformation or movement due to external forces in the in-plane or out-of-plane directions, and the operation The external force caused by this is distributed over the entire panel via the reinforcement bars 4,
Without local forces acting on the ALC panel,
This prevents damage to the mounting bracket and ALC panel.
Further, as a feature of the present invention, in addition to the above-mentioned effects, there is an effect that the mounting brackets can be arranged with high positional accuracy. With conventional embedded metal fittings, the positional accuracy in the in-plane direction of the panel was directly affected by manufacturing errors in the reinforcing bar cage. However, according to the embedded fitting of the present invention, the manufacturing error of the reinforcing bar cage can be absorbed by the width x of the flange flat portion 8 in FIG. 2, and the mounting fitting can be mounted with high positional accuracy. Furthermore, since there is no need for forced positioning such as bending or adding reinforcing bars, there is also the effect of greatly improving work efficiency.

The embedded metal fitting of the present invention has a cross section of the above embodiment.
It is not limited to shapes, but perpendicular 3
It may also be a flat H-shaped steel. The point is that the end portion to be welded to the reinforcing bar has a flat surface with a width sufficient to absorb production errors of the reinforcing bar basket, and has a structure with high three-dimensional rigidity.
