It goes through.

An apparatus for manufacturing an inorganic exposed corner panel according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view for explaining attachment of a side plate to a mold according to the present invention, and FIG.
It is a perspective view for demonstrating attachment of a lid to the type | mold.

The mold A is provided with a surface mold 1 forming the surface of an inorganic exposed corner panel having an L-shaped cross section and an end portion provided on the peripheral edge of the surface mold 1 and forming the peripheral edge of the inorganic exposed corner panel. A mold 2 including a mold 2a and a side mold 2b is provided. In addition, the side plate 5 can be detachably fixed to the inner surface of the end frame 2a at both ends of the mold body 2 in a flush manner. The side plate 5 is formed of a substantially triangular plate 51 and a flange plate 52 attached to two sides of the plate 51. Flange plate 5
2, two bolt insertion holes 52a are provided. The end form 2a is provided with four bolt holes 21 which are internally threaded at positions matching the bolt insertion holes 52a. Similarly, a plurality of bolt holes 21 are formed in the side frame 2b.
Is provided. The side plate 5 and the mold A are detachably fastened by inserting a bolt (not shown) through the bolt insertion hole 52a and screwing the bolt into the bolt hole 21.

The cover 4 is provided with a plurality of bolt insertion holes 4a at positions corresponding to the plurality of bolt holes 21 provided in the mold 2, and the cover A is formed on the mold A with bolts (not shown). 4 can be detachably fastened.

Since the apparatus for manufacturing an inorganic corner panel of this embodiment is constructed as described above, the side plate 5 is fastened to the mold A by bolts, and a predetermined amount of the inorganic curable composition is applied to the mold A.
Can be prevented from flowing out of the mold by the side plate 5 when it is put into the mold. Further, after the inorganic curable composition is formed into the shape of the outer corner panel, the side plate 5 is removed, and the lid 4 forming the back surface of the inorganic outer corner panel is easily placed and fixed on the mold frame 2 to fix the inorganic curable composition. By curing the composition and removing the lid 4, the inorganic exposed corner panel can be released. Further, the inorganic curable composition adhered in contact with the side plate 5 can be removed from the side plate 5 before being cured.

Next, a method of manufacturing the inorganic exposed corner panel will be described. FIG. 3 is a schematic cross-sectional view showing a state in which the inorganic curable composition is put into the mold of FIG. 1, and FIG. 4 is a schematic cross-sectional view showing a state in which the inorganic curable composition of FIG. is there. The inorganic curable composition 6 which is a raw material of the inorganic exposed corner panel is charged in a state where the side plate 5 is attached to the mold A. The mold A is provided with a mold 2 including an end mold 2a and a side mold 2b on a surface mold 1 having an uneven pattern on the surface.
The amount of the inorganic curable composition 6 that satisfies the mold A exceeds the upper end of the end mold 2a at the valley of the mold A. Therefore, as shown in FIG. 3, the inorganic curable composition 6 is held in the mold A by providing the side plate 5 indicated by a dashed line. Next, as shown in FIG. 4, using a spatula or a roller, the inorganic curable composition 6 is formed into an out-of-corner panel shape, and then the side plate 5 is removed, and a lid 4 that forms the back surface of the inorganic out-of-corner panel Is mounted on the mold frame 2 and fixed, and the inorganic curable composition 6 is cured, whereby the inorganic exposed corner panel 6a can be manufactured.

Next, a method for manufacturing a foamed inorganic exposed corner panel will be described. FIG. 5 is a schematic cross-sectional view showing a state in which the inorganic curable composition charged into the mold of FIG. The foamable inorganic curable composition 6 is charged into a mold A having a surface mold 1 and a mold frame 2 for forming a concavo-convex pattern on the inorganic exposed corner panel, and the inorganic curable composition 6
Is formed in the shape of a corner panel, and a foaming allowance 9 is formed on the upper surface of the inorganic curable composition 6, the lid 4 is placed and fixed, the inorganic curable composition 6 is foamed, and the inorganic curable composition is formed. 6 can be manufactured by the procedure of hardening the foamed inorganic material.

Here, the foaming margin 4 needs to have an appropriate shape according to the shape of the inorganic exposed corner panel and an appropriate size according to the expansion ratio. Unless a foaming allowance having an appropriate shape and dimensions is provided, the obtained foamed inorganic material corner panel locally has a different specific gravity and strength. In other words, a product having a specific gravity and a strength distribution which are locally greatly different from each other in the foamed inorganic material corner panel is produced. Unless a foaming allowance having an appropriate size is provided, an excessive foaming pressure is generated in the mold A, and the thickness of the panel becomes thicker than the intended size, and when the panel is severe, the mold A is damaged. Will occur.

Accordingly, before the foaming of the inorganic curable composition 6 proceeds, the inorganic curable composition 6 is formed into a shape of an outgoing corner panel, and a foaming allowance 9 is formed on the back side of the inorganic outgoing corner panel. Foaming is an effective means for ensuring the quality of the inorganic corner panel.

FIG. 6 is a schematic sectional view for explaining a method of forming the foaming allowance 9 in FIG. Here, the inorganic curable composition 6 is scraped and formed into the shape of the corner panel by reciprocating several times in the longitudinal direction using the contact plate 7, and the foaming margin 9 is formed on the back side of the inorganic corner panel. Is formed.

Next, another method for forming the foaming allowance 9 will be described. In this method, the foaming margin 9 is dropped and the lid 8 is used to form. FIG. 7 is a schematic cross-sectional view for explaining another method for forming the foaming allowance in FIG. 5, and FIG. 8 is a schematic cross-sectional view for explaining the foaming allowance in FIG. The inorganic exposed corner panel of the present invention can be formed by molding the inorganic curable composition 6 into the shape of an exposed corner panel, forming a foaming allowance 9 on the back side of the inorganic exposed corner panel, and foaming the same. However, it is desirable to perform vibration degassing. This is because, if not defoamed, when the inorganic curable composition 6 is poured into the mold A, air is trapped or entangled between the surface mold 1 and the inorganic curable composition 6, thereby causing inorganic matter to escape. This is because defects that impair the appearance of the corner panel frequently occur. In addition, as a method of defoaming, a method of giving vibration to the mold A in a horizontal or vertical direction is effective.

As shown in FIG. 7, a method for forming the foaming allowance 9 while shaking and defoaming is to drop the lid 8 on the back side of the inorganic curable composition 6 in the mold A by shaking and removing. While foaming
It is effective to secure the foaming allowance 9 to the mold body A by dropping, and to form the foaming allowance 9 at the same time as defoaming. Further, as shown in FIG. 8, after stopping the vibration, the drop-off lid 8 is taken out, the lid body 4 is placed, and the inorganic curable composition 6 is foam-cured to thereby form a foamed inorganic material corner panel having excellent quality and appearance. Can be manufactured.

As described above, when the dropping lid 8 is dropped into the mold body A, the inorganic curable composition 6 is fluidized by applying vibration, and defoaming can be performed with energy saving. The appearance quality of the corner panel can be ensured, and the drop lid 8 can be dropped efficiently with a small force.

FIG. 3 shows a state in which the upper surface of the inorganic curable composition 6 shown in FIG. It is more effective that the upper surface of the inorganic curable composition 6 is free (that is, it is a space).

For example, as horizontal vibration, the excitation acceleration is 2G.
Table 1 shows the results of the evaluation of the appearance of the inorganic exposed corner panel in the case where the molds A and 6G were provided. The material rheological properties at this time are about 140 to 160 mm in a slump flow test, and the material includes a SiO ₂ —Al ₂ O ₃ -based reactive powder containing SiO ₂ and Al ₂ O ₃ as constituent components, An inorganic curable composition containing a metal silicate and water was used.

[0034]

[Table 1]

As is apparent from Table 1, the excitation acceleration is 2
It can be seen that even with G, if the upper surface of the inorganic curable composition 6 is not constrained, it exhibits the same appearance as the vibration acceleration of 6G in the constrained state. The difference in the appearance of the defoamed state is that, in general, in the case of an inorganic material, it is possible to improve the fluidity by applying vibration (for example, a vibration that is often performed with concrete which is a general inorganic material). This is considered to be caused by compaction and defoaming due to the above.) However, in the state where the upper side of the material is constrained, the degree of improvement in the fluidity is different, and this is considered to occur.

That is, in order to perform vibration defoaming with less energy, the inorganic curable composition 6 is charged into the mold A, vibrated and defoamed, then dropped while foaming with the lid 8. It is preferable to form the margin 9 and remove the drop lid 8 before fixing the lid 4 to the mold A. Here, if the drop lid 8 is detachably fixed to the lid body 4, the inorganic curable composition 6
Can be dropped without leaking. further,
The drop lid 8 can be dropped so as to match the angle of the surface mold 1.

The force required to drop the dropping lid 8 is smaller when the fluidity of the inorganic curable composition 6 is improved. For example, drop the lid 8 on the lid 4
Is fixed, and when vibrating, the lid 4
(With a surface pressure of about 9.8 kPa).
On the other hand, if vibration is not applied, it cannot be dropped unless force is applied. That is, when dropping the lid 8 into the mold A,
Excitation is an effective means in productivity and energy efficiency.

FIG. 9 is a side view showing another embodiment of the apparatus for manufacturing an inorganic exposed corner panel according to the present invention. Form 2 of Form A
The lid 4 is placed on the upper surface of the base 10, and the surface mold 1 and the lid 4 are fastened by tightening the bolts 10 a of the clamp 10. Further, the side plate can be similarly fastened to the mold body A by a clamp. In other words, by using a clamp such as the clamp 10 that can fasten the surface mold 1 and the lid 4 from outside thereof, the bolt insertion holes 51a and 4a and the bolt holes as shown in FIGS. There is no need to provide the mold 21, the cover 4, and the side plate 5, so that the manufacturing cost of the manufacturing apparatus of the inorganic exposed corner panel can be reduced. Further, the arm of the clamp 10 which is in contact with the back surface of the front mold 1 is connected to the front mold 1
If a pivotal support structure such as a hinge is provided between the arm and the arm provided with the bolt 10a,
The mold body A and the lid body 4 can be easily fastened.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like that do not depart from the gist of the present invention. Are also included in the present invention.

For example, the foaming allowance 9 is changed to the inorganic curable composition 6
May be applied to the mold A with a spatula, or may be formed by squeezing with a roller. Further, first, the inorganic curable composition 6 is formed in conformity with the upper surface of the mold 2, and before the lid 4 is placed, a spacer having a height corresponding to the foaming allowance 9 is placed on the mold 2. The cover 4 may be placed and fixed after compensating for the height of the formwork 2.

The cover 4 may be provided with a rib structure for reinforcement. Further, it is effective that the rib is provided with an opening at a valley of the lid 4 so that water condensed on the lid 4 flows out.

When the viscosity of the inorganic curable composition 6 is relatively low (about 170 mm or more in a flow test), the net-shaped or film-shaped back surface is used to keep the material in the shape of the corner panel. A reinforcing material may be added.
