Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete opening panel that enhances the design effect of the outer wall of a building.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, an integrally molded concrete opening panel generally has an opening 1 only in the central portion of the panel surface and a frame 3 around the opening 1. is there. This is because when the bottom side of the panel is removed to form a gate shape, the legs on both sides of the opening 1 are in a single-supported state, and the thinner it becomes, the lower the leg strength (rigidity) becomes, resulting in deformation during loading and construction. This is because it becomes easier. For this reason, in the concrete opening panel, the legs are formed in a connected state, and the rigidity is secured. In the conventional concrete opening panel, such frame shape prevents the panel from being damaged (twisted, bent, etc.) during transportation.

[0003]

However, when the conventional concrete opening panel is used for the outer wall of the building for the purpose of diversifying the design, the panel body is exposed at the lower end of the opening 1 after installation. At the same time, the opening area of the opening 1 is restricted within this limit, resulting in an opening that impairs the feeling of openness in terms of design. Further, as shown in FIG. 5, there is also a piece assembly type concrete opening panel that connects the horizontal member 5 and the left and right vertical members 7, 9, but when this is used, the panel has a lower end. Although it has an open gate shape, the assembly of each piece is complicated and the working time is greatly increased.

The present invention has been made in view of the above situation, and by devising a panel joint portion, it can be constructed so that only joints other than the leg portions can appear between adjacent panels so as to form an integrally molded gate-shaped concrete. (EN) Provided is an apertured panel, which is intended to maintain strength and improve design.

[0005]

A concrete opening panel according to the present invention for achieving the above object is a concrete opening panel in which a central portion of a panel body is cut out including a lower side to form a gate shape. The auxiliary beam member is laid across the lower end surfaces of both leg portions forming the gate shape. In addition, the concrete opening panel is a concrete opening panel in which the center part of the panel body is cut off including the lower side to form a gate shape, and the mounting metal fittings connected to the frame or the lower adjacent panel side are formed into a gate shape. It may be characterized in that it is fixed to the lower ends of both legs.

[0006]

The panel main body is integrally formed in a gate shape, and the auxiliary beam members are erected on the lower end surfaces of the legs, so that the rigidity of the legs is increased and the weight is less likely to be damaged by external force.
Since the mounting brackets are arranged at the lower ends of both legs of the panel body, and the mounting brackets are integrally connected with the holding metal on the upper side of the lower adjacent panel, the appearance of the joint between the upper and lower parts of the panel is on the appearance. Only the opening has an open appearance and has an excellent appearance.

As shown in FIG. 1, the panel body 11 has an integrally formed gate shape in which the central portion is cut off including the lower side, and the openings 13 are formed with legs 15 and 17 on both sides. Legs 15,
An auxiliary beam member 19 having an L-shaped cross-section in a direction orthogonal to the longitudinal direction is fixed to the lower end surfaces 15a and 17a of the both ends 17, and the horizontal side 19a of the auxiliary beam member 19 has a lower end surface 15a,
By being fixed to 17a, the standing piece 19b is in a suspended state. The vertical piece 19b has a pair of mounting brackets 2 with screws.
1 is fixed, and the mounting bracket 21 has a screw insertion direction in a direction orthogonal to the front and back surfaces of the panel body 11.

By the way, the panel main body 11 to which the auxiliary beam member 19 is fixed is fixed to the frame beam 23 by two sets of holding hardware 25. A part of the holding hardware 25 is the panel body 1
1 is used as a jig for suspending a concrete panel 27 disposed below 1. The holding hardware 25 includes a ruler member 29, a flat plate fastener 31, and a locking fastener 33. The ruler member 29 is a steel material having an L-shaped cross section, and is fixed by welding in a pair in the longitudinal direction of the frame beam 23. The horizontal piece 29a is fixed to the ruler member 29 by welding, so that the vertical piece 29a
b is erected. In addition, the ruler member 29
Has a length that can also be used as a holding metal for a panel adjacent to the side of the panel body 11.

On the other hand, a horizontally long mounting hole 35 is formed in the upper portion of the flat plate fastener 31, and the mounting bolt 37 inserted in the mounting hole 35 is mounted on the leg portion of the panel body 11 by the mounting bracket 2.
It is designed to be screwed into 1. Also, flat fastener 3
A pair of vertically long mounting holes 39 are formed in the lower part of the plate 1, and mounting bolts 41 for fixing the locking fasteners 33 of the lower adjacent panel to the panel 27 are inserted into the mounting holes 39. The seat plate 43 of the locking fastener 33 has a pair of mounting holes 45 through which the mounting bolts 41 are inserted. That is, the mounting bolt 41 is inserted and screwed into the concrete panel 27, so that the flat plate fastener 31 and the locking fastener 33 are fastened together. The seat plate 43 is provided with a locking piece 47 projecting from the standing piece 29b of the ruler member 29, and the locking piece 47 has a notch 49 for locking the standing piece 29b.
Are formed.

A construction procedure of the concrete opening panel constructed as above will be described. After the ruler member 29 is positioned and welded and fixed to the frame beam 23, the flat plate fastener 31 and the locking fastener 33 are overlaid on the upper part of the concrete panel 27 arranged below and temporarily fixed by the mounting bolt 41. In this state, the concrete panel 27 is lifted, the notch 49 of the locking fastener 33 is aligned with the standing piece 29b of the ruler member 29, and is lowered to be engaged. After engaging the lower concrete panel 27 as described above, the panel body 11
Hang up. Then, the mounting bracket 21 at the lower end of the leg portion of the panel body 11 is aligned with the mounting hole 35 of the flat plate fastener 31, and the mounting bolt 37 is tightened and fixed with a predetermined torque, and the mounting bolt 41 is tightened and fixed. Panel body 1
1. After the concrete panel 27 and the skeleton beam 23 are assembled through the holding metal fitting 25, each connection part of the holding metal fitting 25, and each bolt, washer, etc. in contact with these are further spot-welded, After fixing and locking, the installation work of the concrete opening panel is completed.

According to the above concrete opening panel, the panel is mounted by the mounting metal fitting 21 arranged below the panel body 11 via the holding metal 25, so that the leg portion 15 appears between the upper and lower sides of the panel. , 17 joints, it is possible to obtain an appearance with an open feeling and a good design. In addition, since the panel body 11 can be integrally formed in a gate shape, it can be mounted on the body extremely easily and quickly as compared with the piece assembly type. Further, since the auxiliary beam members 19 are installed on the lower end surfaces 15a and 17a of the leg portions 15 and 17, the rigidity of the legs is increased, and the panel damage during transportation can be prevented. Further, the leg portion 1 is formed by using the auxiliary beam member 19 as a cross member having an L-shaped cross section as in the above-described embodiment.
Even if it is attached to the frame while being installed between Nos. 5 and 17, it does not stand out in appearance, and can be used as a jig for attaching equipment materials such as a sash.

In the above embodiment, the auxiliary beam member 19 and the mounting bracket 21 are fixed to each other, but this prevents the auxiliary beam member 19 and the mounting bracket 21 from being used alone. For example, the mounting bracket 21
When used alone, the mounting member 21 is directly fixed to the leg portions 15 and 17. Therefore, the auxiliary beam 1
9 is detachable, and may be attached only during transportation as described above and may be detached at the construction site, and can be used as a so-called temporary beam material. Further, it goes without saying that a configuration in which the panel body 11 is stretched vertically and horizontally as an opening panel is also possible. Furthermore, although the mounting member 21 is connected to the locking fastener 33 by the flat plate fastener 31, the flat plate fastener 31 can be directly locked to the ruler member 29 as an internal type. In this case, the flat plate fastener 31 and the locking fastener 3
It is necessary to shift the positions of 3 and arrange them.

[0013]

As described in detail above, in the concrete opening panel according to the present invention, since the auxiliary beam member is installed over the lower end surfaces of both legs, the panel body can be integrally formed in a gate shape. Moreover, the rigidity of the legs is improved, the damage due to its own weight and external force does not occur, and it is possible to prevent the panel from being damaged during transportation. Also, if the mounting brackets connected to the body side are fixed to both legs so that they can be hidden,
Easy and quick installation on the body,
Only the joints of the legs appear between the top and bottom of the panel, and the openings can be excellent in design.
