In FIGS. 1 to 4 and 13, reference numeral 1 denotes a core member that forms a core material Cm used in an example of the security panel SP of the present invention, and has the following configuration. That is, the core member 1 is formed by bending a long steel plate having a thickness of at least 0.6 m and a width of about 60 to 70 mm into a substantially L-shaped cross section to form a vertical side 1a and a horizontal side 1b. On the side 1a, a narrow groove 1c is formed at a pitch of about 50m and having a depth of about 1/2 of the height of the vertical side 1a, and a cut-out of about 15 mm on one side is formed in an intermediate portion of each cut groove 1c. The hole 1d is formed. Here, on the lower side of the cut and raised hole 1d, a cut and raised piece 1e is projected in a horizontal posture from the vertical side 1a. The dimension values of the core member 1 are merely examples, and the core member 1 used in the security panel SP of the present invention has a core member form other than the above numerical values, or a core member using a core member of another material and shape. The material Cm may be used.

As described above, the core member 1 that forms the vertical and horizontal members 1v and 1h cut to a fixed length such that the positions of the narrow grooves 1c are aligned with the members 1v and 1h is, for example, a plurality of the core members 1. Is a vertical member 1v, and its horizontal side 1b is positioned downward (the narrow groove 1c is directed upward) and vertically arranged horizontally, while the horizontal member 1h corresponding to the arranged vertical member 1v is attached to its horizontal side 1b. In the arrangement, the narrow groove 1c of the horizontal member 1h is placed in each of the narrow grooves 1c of the vertical members 1v arranged in parallel. The vertical and horizontal members 1v and 1v are combined as shown in FIG. 1 to show the main part in a planar shape, FIG. 2 shows the main part in a front state, and FIG. 3 shows the main part in a side state. The whole 1h forms the core material Cm in a lattice shape.
[0014]
In the core member Cm formed as described above, the vertical sides 1a of all the core members 1 used are used as the vertical members 1v and the horizontal members 1h, and are assembled in a lattice shape. , Lower horizontal sides 1b, 1b, and each cut-and-raised piece 1e is located in a state protruding inward from the peripheral wall surface of each lattice, so that approximately 1/2 of the lattice viewed from a plane. In this case, the components of the core member 1 made of a steel sheet exist in a substantially uniform distribution state, and the core material Cm having a high cone resistance is formed.
[0015]
As illustrated in FIG. 4, the core material Cm sandwiches the upper and lower surfaces of the lattice surface between, for example, a surface outer skin 2 and a rear surface outer skin 3 made of a steel plate, and has the left and right side surfaces of the core material Cm. The upper and lower end surfaces are sandwiched between left and right side frame members 4 and 5 attached to the outer skins 2 and 3 corresponding to the respective surfaces, and upper and lower end frame members 6 and 7. , Positioned between the front and back skins 2, 3. Reference numeral 2a denotes a mortar injection hole provided at a corner of the surface outer skin 2, and this injection hole 2a may be provided anywhere on the outer skin. Further, as the material of the outer skins 2 and 3, a metal plate other than a steel plate may be used.
[0016]
Here, the structural examples of the left and right side frame members 4 and 5 and the upper and lower end frame members 6 and 7 and the heat shielding function in the above-described security panel SP of the present invention are shown in FIGS. 4 and 7 to 10. It explains while doing. The top and bottom sides of the left and right side frame members 4 and 5 in FIGS. 4, 7 and 8 are shown upside down, but in the security panel SP of the present invention, the top and bottom directions of the side frame members 4 and 5 are the same. Alternatively, the present invention can be applied to any orientation of FIGS. 7 and 8 without any problem.
[0017]
In FIG. 4, the left side frame member 4 includes a first vertical frame member 4a having a substantially U-shaped cross section, a second vertical frame member 4b having a substantially step-shaped U-shaped cross section, and a casing sandwiched between the two members 4a and 4b. It is formed by a heat shielding member 4c made of an inorganic material such as a calcium oxide plate, and is formed on the side frame 4 having a concave groove 4d on the outer surface with a sectional structure shown in FIG.
[0018]
On the other hand, the right side frame member 5 in FIG. 4 is sandwiched between a third vertical frame member 5a having a substantially crank-shaped cross section, a fourth vertical frame member 5b having a substantially stepped U shape, and both members 5a and 5b. The side frame 5 is formed by a heat-insulating member 5c made of an inorganic material such as a calcium silicate plate, and has a cross-sectional structure shown in FIG. I have.
[0019]
In the left and right side frame members 4 and 5, the heat shielding members 4c and 5c are inserted between the upper and lower vertical frame members 4a and 4b, and similarly between the vertical frame members 5a and 5b. The purpose of this is to prevent a heat bridge phenomenon between the front outer skin 2 and the rear outer skin 3 to which the side frames 4 and 5 are attached. It is optional to use an inorganic material other than the above-described heat shield members as the heat shield members 4c and 5c.
[0020]

The fact that the inner side of the outer skin is bent is the same as the heat shielding members 4c and 5c in the side frame members 4 and 5 and suppresses a heat bridge between the front and rear outer skins 2 and 3 at the same time. This is because the letter-shaped portion is buried inside the filled mortar Mo to enhance the heat bridge suppressing effect.
[0022]
With the core material Cm placed inside the outer skin as described above, the core material Cm is attached to the front and back outer skins 2, 3, the left and right side frame members 4, 5, and the upper and lower end frame members 6, 7. When covered with the outer skin formed by the above, a gap g remains between the L-shaped portions 6a, 6b and 7a, 7b in the upper and lower end face frame bodies 6, 7, and the foam mortar Mo cannot be injected into the outer skin. .
