Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a decorative column using ALC, and can be used for manufacturing a decorative pouch column for a building, for example.

[0002]

[Background Art] A decorative pouch pillar of a building is conventionally composed of a core material such as a square steel pipe and a panel made of lightweight cellular concrete (ALC) arranged on the four circumferential side surfaces of the core material. The panel was attached to the four sides of the core with brackets and other mounting hardware.

[0003]

According to such a conventional decorative pouch column, there is a problem that the structure is complicated because a mounting hardware such as a bracket is required, and the ALC panel is used as a mounting hardware. Since it has to be attached to the core material, much work is required for this work, and there is a problem in workability.

An object of the present invention is to provide a method for manufacturing a decorative column, which has a simple structure and facilitates manufacturing.

[0005]

According to the first aspect of the present invention, a core material is placed in a column-forming mold, and then a concrete slurry is poured into the mold to cure the slurry. A feature is that a pillar material containing a core material is made in the mold, the pillar material is taken out from the mold, and the pillar material is autoclaved to manufacture a decorative pillar.

According to a second aspect of the present invention, a core material is placed in a mold for partially molding a column, and then concrete slurry is poured into the mold, and the slurry is hardened. Make a pillar partial material with a core material in the mold, take out this partial material from the mold, and then cure the partial material by autoclave to make a pillar partial member, combine multiple partial members and make up It is characterized by manufacturing pillars.

[0007]

In the first aspect of the present invention, a concrete column is manufactured by placing concrete slurry in a mold in which a core material is placed, taking out the column material by hardening the slurry, and curing it in an autoclave. It is possible to manufacture a decorative column by the same operation as the production of a lightweight cellular concrete in which a concrete slurry is poured into a mold and the material obtained by this is an autoclave curing.

According to the second aspect of the invention, since a decorative column is manufactured by joining a plurality of partial members made by casting concrete slurry into a mold and curing an autoclave of partial materials, it is a case of a large decorative column. However, by dividing this into a plurality of partial members for manufacturing, the manufacturing work can be facilitated.

[0009]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a house 1 to which a decorative pillar according to the present embodiment is applied. The decorative pillar is a front porch pillar 4 provided to support a front roof 3 on a front porch 2 of the housing 1. Is.

FIG. 2 shows a core member 5 embedded inside the entrance porch pillar 4. The core material 5 includes a main bar 6 that is long in the vertical direction,
It consists of a top plate 7 and a base plate 8 provided at both ends of the main reinforcement 6, and an auxiliary reinforcement 9 extending in a branch shape from the main reinforcement 6, and these are made of metal. As shown in FIG. 3, the core material 5 is put in a column molding mold 10 having a length corresponding to the length of the core material 5. The mold 10 includes a bottom plate 11, a front plate 12 and a rear plate 13 on both end sides of the core member 5, left and right side plates 14 and 15 of the core member 5 (side plate 15 is not shown in the drawing),
And the upper plate 16 shown in FIG.

A pattern sheet 17 is previously attached to the bottom plate 11, the side plates 14 and 15, and the upper plate 16. The pattern sheet 17 is formed with a pattern corresponding to the pattern due to unevenness to be formed on the surface of the completed entrance porch pillar 4.

As shown in FIG. 3, the form 1 with the upper plate 16 removed
After arranging the core material 5 in 0, the raw material slurry of lightweight cellular concrete is placed in the mold 10. This raw material slurry contains cement and silica as main components, and further contains air bubbles. After the raw material slurry has been cast, the mold 10 is covered with the upper plate 16.

This raw material slurry is aged for a predetermined time to be primarily hardened. As a result of this curing, as shown in FIG.
Within 0, a pillar material 18 containing a core material 5 is made. An uneven pattern formed by the pattern sheet 17 is formed on the surface of the pillar material 18. After that, the mold 10 is attached to the upper plate 16 and the front and rear plates 1.
2, 13 and the side plates 14, 15 are disassembled to disassemble, and the pillar material 18 is taken out from the inside.

After that, the pillar material 18 is carried into a pressure cooker to which high temperature steam is supplied for autoclave curing, and the pillar material 18 is cured in the pressure cooker at a high temperature and a high pressure.

The pillar material 18 carried out from the pressure cooker is sent to the painting process and the surface is painted. As a result, as shown in FIG. 5, the entrance porch pillar 4 made of lightweight cellular concrete with the core material 5 embedded therein is completed. The entrance porch pillar 4 has the entrance porch 2 and the entrance roof 3 shown in FIG. 1 by the top plate 7 and the base plate 8 exposed to the outside.
To be joined to.

In this embodiment, the pillar material 18 is made by placing concrete slurry in the mold 10 in which the core material 5 is arranged as described above, and the pillar material 18 taken out from the mold 10 is subjected to autoclave curing. Since the entrance porch pillar 4 is manufactured by the above, compared to the conventional decorative pillar in which the panel made of lightweight cellular concrete is attached to the four circumferential side surfaces of the core material with the bracket or the like mounting hardware, the bracket or the like mounting hardware is unnecessary. Therefore, simplification of the structure can be achieved, and since it is not necessary to attach a panel made of lightweight aerated light concrete, the labor of the operation can be omitted and the manufacturing can be simplified.

6 to 9 show another embodiment of the present invention. In this embodiment, when the entrance porch pillar has a large width, the pillar is manufactured by manufacturing the partial members divided into two in the width direction and connecting them.

In FIG. 6, a core material 25 is put in the mold 30. The core member 25 is composed of a main bar 26, a top plate 27, a base plate 28, and an auxiliary bar 29, and has the same structure as the core member 5 of the above-described embodiment divided in two in the width direction. The formwork 30 includes a bottom plate 31, front and rear plates 32, 33.
And side plates 34, 35 (the side plate 35 is not shown in the drawing) and the upper plate 36 shown in FIG. The pattern sheet 37 is attached to the bottom plate 31 and the side plates 34 and 35.

When the core member 25 is put into the mold 30 from which the upper plate 36 has been removed, the main bars 26 are at the same level as the upper surface opening height of the mold 30, that is, the upper surfaces of the front and rear plates 32 and 33. The formwork 30 is a formwork for partially molding a pillar obtained by dividing the entrance porch pillar into two in the width direction.

A light-weight cellular concrete raw material slurry is poured into the mold 30, and thereafter, the upper plate 36 is put on the mold 30 as shown in FIG. 7, and the raw material slurry is cured for a predetermined time to be temporarily hardened.

As a result, a column-shaped partial material 38 containing the core material 25 is completed in the mold, and this partial material 38 is taken out from the mold 30. Then, the partial material 38 is subjected to autoclave curing in the pressure cooker.
Then, the partial member 39 of the column shown in FIG. 8 is produced, and this partial member 39 is taken out from the pressure cooker and sent to the coating process for coating.

Two partial members 39 produced in this way are made, and these are superposed so that the main bars 26 exposed on the surface are aligned with each other, and are joined to each other. As a result, the entrance porch pillar 24 made of a lightweight air bubble confill containing the core material 25 is completed. The painting operation may be performed after the two partial members 39 are joined together.

FIG. 9 shows a specific structure for connecting the two partial members 39. A step portion 28A is formed on the base plate 28 of each of the partial members 39. When the partial members 39 are overlapped with each other, the joining plate 40 is inserted into the recess formed by these step portions 28A, and the joining plate 40 is Each base plate 28 is connected with a bolt 41. The same coupling is performed on the side of the partial member 39 on the top plate 27 side.

As a result, the two partial members 39 are attached to the core member 2
The top plate 27 and the base plate 28, which form part 5, are joined together.

According to this embodiment, the same effect as that of the above embodiment can be obtained, and even if the entrance porch pillar 24 has a large width, it is divided into two in the width direction. Since it is manufactured by combining 39, a large entrance porch pillar can be easily manufactured.

Further, since the partial members 39 are joined to each other at the top plate 27 and the base plate 28 of the respective core members 25, the joining strength can be increased.

In each of the embodiments described above, the core members 5, 25
Was formed by the main bars 6 and 26, the top plates 7 and 27, the base plates 8 and 28, and the secondary bars 9 and 29, but the shape and configuration of the core material is not limited to this, and These are arbitrarily determined according to the size, shape, and the like. Further, the decorative columns manufactured according to the present invention are not limited to the entrance porch columns, and the manufacturing method of the present invention can be applied to, for example, a decorative column for supporting a balcony of a building, and the use of the decorative columns is arbitrary.

Further, when the decorative column is constituted by connecting a plurality of partial members, these partial members are not limited to those divided in two in the width direction of the column, and for example, three in the width direction. It may be divided or divided, or may be divided into a plurality of pieces in the length direction.
