BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a security panel and its core material used for producing a side wall of a safe room or the like that requires fire resistance and cone resistance.
[0002]
[Prior art]
Conventionally, when manufacturing the surrounding wall of a vault, which requires fire resistance and cone resistance, it is manufactured by forming a steel plate into a box shape and pouring mortar mixed with cone resistant material into the box. In general, a wet type security panel is used, and the mortar ensures the fire resistance and heat resistance of the security panel and also provides the anti-theft property by providing the cone resistance.
[0003]
In a conventional wet-type security panel, a mortar is filled in a panel skin formed of a steel plate in a box shape and solidified to form a security panel. For this reason, in the case of a wet manufacturing method security panel, it was necessary to prepare and stock the panel in advance in order to quickly respond to demand. However, a wet-processed security panel filled with mortar mixed with conical-resistant material tends to increase the weight of the panel itself, so handling such as stock storage and loading / unloading at the storage location is difficult. There was a problem that it was not easy.
[0004]
Therefore, recently, instead of mortar mixed with cone-resistant materials, etc., a dry panel such as an asbestos slate system panel previously formed as a block panel as a refractory material is used as a core material, and this core material is covered with a steel plate Things came to be used. Since the fireproof material (core material) by the dry panel is relatively lightweight, when making a security panel to be used for the side wall of a vault, etc. using this, compared to the conventional security panel of the mortar filling type wet manufacturing method, While it can be manufactured at work sites such as vaults and is relatively lightweight, it is easy to handle and has excellent fire resistance, but the outer surface of the dry panel core is covered with an iron plate. Since it is formed on the security panel simply, it is inferior in conical resistance, and it was easily perforated together with the iron plate by a sharp tool such as a drill or an instrument.
[0005]
Moreover, when producing a security panel using an off-the-shelf dry panel as a refractory material, usually two refractory materials covered on one side by an iron plate are brought into contact with each other on the surfaces of the refractory material that are not covered by the iron plate. The abutting surfaces are bonded and combined with an adhesive to form a single security panel. However, since the adhesive is used on the entire abutting surface, it takes time to dry the adhesive. There is also a problem.
[0006]
In view of such prior art, the applicant of the present invention uses a lightweight refractory material reinforced with a cone-proof material as a core material, covers the outer periphery with a metal plate, and does not use an adhesive on the contact surface. A security panel of a dry manufacturing method in which the panel can be easily produced on-site by configuring the above has been previously proposed (see, for example, Patent Document 1 and Patent Document 2).
[0007]

JP 2000-291340 A (page 2 to page 3, FIG. 5)
[Patent Document 2]
JP 2002-97844 A (page 3-4, FIG. 6)
[0008]
However, even if the security panel of the conventional dry manufacturing method has a structure in which a refractory core material made of a ready-made dry panel is reinforced with a steel cone resistant material, the core material itself made of the dry panel has low cone resistance. For this reason, it was found that there are some aspects that the overall security resistance of the security panel is not sufficient.
[0009]
[Problems to be solved by the invention]
Therefore, in the present invention, the advantage of the high-cone resistance of the wet manufacturing method security panel is further improved by using the steel core material, while the weight problem due to the mortar core material, which is a difficulty of the wet manufacturing method security panel. The challenge is to provide a security panel that reduces the risk.
[0010]
[Means for Solving the Problems]
The structure of the security panel of the present invention, which has been made to solve the above-mentioned problems, is formed by forming longitudinal narrow grooves at equal pitches in the length direction of an elongated metal plate having a substantially L- shaped cross-section, and each thin panel. A plurality of plate-like core members cut and raised between the grooves are arranged in parallel with the fine grooves facing upward, while the fine grooves are directed downward with respect to the parallel arranged core members, and A plurality of plate-like core members arranged in parallel in a direction orthogonal to the core member are assembled into a planar grid-like core material by fitting the opposing narrow grooves of both core members, and this grid-like core material Is covered with a metal plate-made outer skin member, and the inside of the outer skin member is filled with lightweight mortar.
[0011]
The configuration of the core material for the security panel according to the present invention is such that a longitudinal narrow groove is formed at an equal pitch in the length direction of an elongated steel material having a substantially L- shaped cross section, and a cut and raised hole is formed between each narrow groove. The plurality of provided plate-like core members are arranged in parallel with the fine grooves facing upward, while the fine grooves are directed downward and perpendicular to the core members with respect to the core members arranged in parallel. A plurality of plate-shaped core members arranged in parallel are assembled in a planar lattice shape by fitting the opposing narrow grooves of both core members.

[0013]
1 to 4, reference numeral 1 denotes a core member that forms the core material Cm of the security panel SP of the present invention, and has the following configuration as an example. 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. In 1a, a narrow groove 1c is formed by a notch having a depth of about 1/2 of the height of the vertical side 1a at a pitch of about 50 m, and one side is cut and raised about 15 mm in the middle of each of the notches 1c. A hole 1d is formed. Here, in the lower side of the cut and raised hole 1d, the cut and raised piece 1e protrudes from the vertical side 1a in a horizontal posture. In addition, the dimension numerical value of the said core member 1 is an example, Comprising: Of course in the present invention, the form of the core member 1 other than the said numerical value may be sufficient.
[0014]
The core member 1 is composed of a strip steel plate having a length of about 3 m or 4 m, for example, by forming each component from the vertical side 1a to the cut piece 1e by pressing to form a core material Cm. The vertical member 1v and the horizontal member 1h are cut to the respective lengths. The lengths of the vertical member 1v and the horizontal member 1h correspond to the height and front width of the security panel of the present invention. In the cutting, the members 1v and 1h are cut so that the positions of the narrow grooves 1c from the end surfaces of the members coincide (see FIG. 13).
[0015]
As described above, a plurality of core members 1 are formed as an example to form the vertical and horizontal members 1v and 1h that are cut to a predetermined length so that the positions of the narrow grooves 1c are aligned with the members 1v and 1h. Is the vertical member 1v, the horizontal side 1b is positioned downward (that is, the narrow groove 1c is directed upward), and the horizontal member 1h corresponding to the arranged vertical member 1v is horizontally aligned. 1b is positioned upward (that is, the narrow groove 1c is directed downward) and is arranged in a horizontal orientation. In this arrangement, each narrow groove 1c of the vertical members 1v arranged in parallel is arranged with the horizontal member 1h Inserting the narrow groove 1c, the main part of the planar shape is shown in FIG. 1, the main part in the front state is shown in FIG. 2, and the main part in the side state is shown in FIG. The members 1v and 1h as a whole form a lattice material Cm.
[0016]
The core material Cm for the security panel of the present invention formed as described above is assembled in a lattice shape with the vertical sides 1a of all the core members 1 used as the vertical members 1v and the horizontal members 1h. Each vertical side 1a is reinforced by the upper and lower horizontal sides 1b and 1b, and each cut-and-raised piece 1e is located in a state of projecting inward from the peripheral wall surface of each lattice. The area of approximately 1/2 of the lattice has the components of the core member 1 made of a steel plate in a substantially uniform distribution state, and is thus formed in the core material Cm having high cone-proof performance.
[0017]
As shown in FIG. 4, the core material Cm is sandwiched between the upper surface and the lower surface of the lattice surface by the surface skin 2 and the back surface skin 3 made of steel panels, and the left and right side surfaces and the upper and lower sides of the core material Cm. In the form in which the end face is sandwiched between the left and right side frame bodies 4 and 5 attached to the outer skins 2 and 3 corresponding to the respective faces, and the upper and lower end face frame bodies 6 and 7, the table, It is positioned between the back skins 2 and 3. In FIG. 4, 2a is a mortar injection hole provided at the corner of the surface skin 2, but this injection hole 2a may be provided anywhere in the skin.
[0018]
Here, a configuration example of the left and right side frame bodies 4 and 5 and the upper and lower end frame bodies 6 and 7 will be described with reference to FIG. 4 and FIGS. 7 to 10 and FIG. 4, 7, and 8, the left and right side frame bodies 4 and 5 are shown upside down, but in the present invention, the side frame bodies 4 and 5 have the top and bottom directions shown in FIG. 7 and 8 can be applied without any problem.
[0019]
In FIG. 4, the left side frame 4 includes a first vertical frame member 4a having a substantially U-shaped cross section, a second vertical frame member 4b having a substantially U-shaped cross section, and a cage sandwiched between both members 4a and 4b. It is formed by a heat shield member 4c made of an inorganic material such as a calcium oxide plate, and is formed on a side frame 4 having a cross-sectional structure shown in FIG.
[0020]
On the other hand, the right side frame body 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. It is formed of a heat shield member 5c made of an inorganic material such as a calcium silicate plate, and is formed on a side frame 5 having a side ridge 5d that can be fitted in the groove 4d on the outer surface in the cross-sectional structure shown in FIG. Yes.
[0021]
In the left and right side frame bodies 4 and 5, the heat shielding members 4c and 5c are inserted between the upper and lower vertical frame members 4a and 4b and between the vertical frame members 5a and 5b, respectively. This is to block the heat bridge phenomenon between the front surface skin 2 and the back surface skin 3 to which the side frames 4 and 5 are attached.
[0022]
Next, as shown in FIG. 4 and FIGS. 9, 10, and 14, the upper and lower end face frames 6 and 7 have cross-sectional L-shaped portions 6a and 6b (end faces) corresponding to the upper and lower symmetrical orientations. In the frame body 7, the same L-shaped portions 7a and 7b) are formed in the form of being joined and integrated by a thin connecting portion 6c having a substantially square cross section near the middle portion and both ends (the connecting portion 7c in the end face frame body 7). The upper L-shaped portion 6a (7a) is joined to the front surface skin 2, and the lower L-shaped portion 6b (7b) is joined to the back surface skin 3, so that It is formed on the upper and lower end face frames 6 and 7.
[0023]
In the upper and lower end frame bodies 6 and 7, the upper and lower L-shaped portions 6a and 6b and 7a and 7b are joined by the thin connecting portions 6c and 7c. The reason is to suppress the heat bridge phenomenon between the front and back skins 2 and 3 with the same meaning as the thermal members 4c and 5c.
[0024]
With the core material Cm placed inside as described above, the core material Cm is formed by the front and rear skins 2, 3, the left and right side frame bodies 4, 5, and the upper and lower end surface frame bodies 6, 7. If the outer skin is covered with the outer skin, gaps g remain between the L-shaped portions 6a, 6b and 7a, 7b of the upper and lower end face frames 6, 7, and the foam mortar Mo cannot be injected into the outer skin.
[0025]

At this time, the vertical frame members 4b and 5b and the L-shaped portions 6b and 7b are adjusted in contact with each other, and the contact portions between the members 4b and 5b and 6b and 7b are also joined by butt welding or the like.
[0027]
The heat shield members 4c and 5c are temporarily fixed to the upper surfaces of the vertical frame members 4b and 5b with a double-sided tape or the like. The upper vertical frame members 4a and 5a in the side frame bodies 4 and 5 are placed on the upper surfaces of the temporarily installed heat shield members 4c and 5c, and are screwed to the lower frame members 4b and 5b through the heat shield members 4c and 5c. Fix with etc.
[0028]
At the time of the fixing, the engagement between the vertical frame members 4a and 5a and the upper L-shaped portions 6a and 7a in the upper and lower end face frame bodies 6 and 7 is adjusted, and the contact portion between the members is welded or the like Join. After this joining, the surface skin 2 is placed on the frame members 4a and 5a and the L-shaped portions 6a and 7a at the positions, and attached by plug welding or the like.
[0029]
The core material Cm is adjusted in the outer skin by welding or the like so that the core material Cm is positioned in the center of the outer skin made of the steel sheet as described above and is adjusted using a liner (not shown). Temporarily fix. Then, the gap g between the upper and lower end face frames 6 and 7 is closed by sticking aluminum tapes 8 and 9, and the foam mortar Mo is injected and filled into the outer skin from the mortar injection hole 2a of the surface outer skin 2 and cured. By doing so, the security panel SP of the present invention is manufactured.
[0030]
The security panel SP of the present invention manufactured as described above is joined to the groove 4d of the side frame 4 on the right side of one security panel SP1, as shown in FIG. This is done by fitting the ridge 5d of the side frame 5 on the left side of the other security panel SP2. At this time, the gap between the joint surfaces of the concave grooves 4d and the ridges 5d is filled with a heating foaming agent to prevent hot air from blowing out. The heating foaming agent can be interposed between the heat shield members 4c and 5c and the vertical frame members 4a and 4b and 5a and 5b.
[0031]
When the security panel of the present invention is placed on the floor F illustrated in FIG. 12, for example, the panel base 10 having a substantially concave cross section supporting the panel from below is placed on the floor F by anchor bolts 11 or the like. The lower part of the security panel of the present invention (the lower end face frame body 7 part) is inserted into and supported by the recess of the base 10. Reference numeral 12 denotes a gypsum board as a heat shield provided on the standing wall of the panel base 10. In the above, the core member 1 and the outer and outer skins 2 and 3 can be formed of a plate made of stainless steel or other appropriate alloy in addition to those made of steel plate.
[0032]
【The invention's effect】
The security panel and the core material of the present invention having the above structure have the following effects.
First, the core material of the panel is formed by assembling a steel plate processed core member into a grid shape, so it is lighter than the core material with reinforcing bars assembled in a grid shape, and the grid core material is a steel plate bending process Since it has been given a form that ensures fracture resistance by cutting and raising, it has high fracture resistance.
[0033]
Since the lattice-shaped core material uses the core member having the same shape as the vertical and horizontal members, the number of parts is reduced, which is advantageous in terms of material cost and processing cost.
[0034]
In addition, since the lattice-shaped core material is formed of vertical sides and horizontal sides, and has cut and raised holes and cut and raised pieces, the contact surface with the mortar to be injected and filled increases, It is possible to provide a security panel that can realize a strong integration of the above and further improve the fire resistance and the fracture resistance such as the cone resistance.
