Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lightweight aerated concrete (hereinafter abbreviated as "ALCj").

This invention relates to a new space expansion method for securing a constant space necessary and sufficient for smooth passage of steam between panel products, and a device for the same.

Generally, when manufacturing ALC panels, a fairly large hardened piece of aerated concrete is cut and divided using tensioned steel wires and then cured in an autoclave, but in the cut state, the gap between the panel products is usually about 1 mm.
However, since the cutting is done using steel wire in an unsolidified state, the cut surface becomes rough and serrated, and foreign matter such as cutting powder can accumulate in the gaps. , the above-mentioned gap of about 1 mm is actually much smaller.

With this cut state in place, the panel product can be converted into a conventional (
For example, as shown in Fig. 5 of Japanese Patent Publication No. 38-21630, when the material is placed on a conveyor belt and then sent into an autoclave for curing, the heat conduction effect is almost the same as that in the state of the nodule before cutting. It takes a considerable amount of time to raise the temperature all the way to the center of the product, which reduces work efficiency.

In addition, regarding the quality of the product, the surface or peripheral area is first steam-cured, and the inner center is cured more slowly, resulting in frequent occurrence of serious defects such as cracks due to unevenness.

The present invention is intended to solve these problems, and is designed to constantly and stably maintain a constant space between panel products divided by cutting, which is necessary and sufficient to allow steam to flow evenly and smoothly. Therefore, we devised a way to easily and reliably expand the use of these products.

Hereinafter, the present invention will be specifically explained based on the illustrated embodiment. FIGS. 1 to 3 show the overall outline of the preferred expansion device, and 1 is a machine-casing type installation frame, and 2 is the same. This is a rail mounting base fixed on the top surface, and a pair of parallel guide rails 3 are laid on this base.

Reference numeral 4 denotes a tension mechanism installed on the installation frame 1, and is composed of a hydraulic cylinder 5 and an expansion arm 7 that is opened and closed by the movement of a piston rod 6 of the hydraulic cylinder 5.

In this regard, in the illustrated example, the tension mechanism 4 is provided as a set of left and right actuated at the time of graduation, and the chain-shaped product receiver described later is used to pull the stand from both ends of the connected length direction at the arrow P in the illustrated example. It is determined that the tension is to be applied evenly in opposite directions shown by , which is intended to improve workability. However, it is also possible to attach a required number of tension mechanisms other than those shown in the drawings to apply the tension from both ends or one end as described above. It is of course possible to do this, and although it is not shown in the figure,
A plurality of the above-mentioned devices are installed in parallel, and the chain-like product receivers connect the ends of the stands between each other in the several rows, for example, by link members, and then connect the ends of the stands to each other in the same manner as above by a single tension mechanism. It is also possible to pull the two parts at the same time, which further improves work efficiency and is suitable for mass production.

Incidentally, the tip of the expansion arm 7 forms a locking claw 8 for securing the product receiver to the table.

9 is the opening/closing fulcrum of the arm 7.

A chain unit A for supporting the following panel products is mounted on the guide rail 3.

That is, in Figs. 4 to 6, which show this in enlarged form, 10
The plurality of product holders arranged in parallel are tables that directly support the cut and divided products M, and have a width W that substantially matches the cut thickness T of the product M, and this The product M is placed on the tray 10 as shown in FIG.

During this work, if the accuracy of the above matching positioning is low and the product M is placed on both sides of the stand 10, there is a high possibility that the edge of the product M will be missing when a tensile force is applied afterwards. Therefore, for the purpose of preventing this, a tapered surface 11 is formed on the opposing end surfaces (seams) of the receiver base 10 to allow relief from the product M.

Reference numeral 12 denotes an ear piece extending from one end or both ends of the juxtaposed end to the base 10, and includes a latch for receiving and locking the distal end latch claw 8 of the expansion arm 7. Hole 13 is opened.

Reference numeral 14 denotes a linear guide frame having a substantially U-shaped cross section, which is integrally fixed to the back side of the table 10 by welding or other means;
As is clear from the figure, the guide rails 3 that form a pair are fitted into each other, and by contact with the rails 3, the pedestal 10
The straightness when moving and the support for the rail 3 are determined by the platform 1.
It has achieved a level of ease of installation of 0.

In addition, the supports 15 with guide frames 14 arranged in parallel are a plurality of plate wall link pieces arranged in parallel and inserted into the U-shaped interior of the guide frames 14 in order to connect adjacent ones of the stands 10 in a chain. Each of them has a set of a long hole 16 and a round hole 11 opened therein.

Reference numerals 18 and 19 denote a pair of connecting pins; one pin 18 passes through the elongated hole 16, and the other pin 19 passes through the round hole 17, and the one pin 18 passes through the long hole 16. , the adjacent pieces 15 are connected to one side of the base 10, and the other pin 19 connects the pieces 15 to each other.
However, the other receiver is connected to the stand 10.

The repetition of this regular connection results in the elongated hole 16
A plurality of supports are provided over the entire base 10 as an alternating arrangement of round holes 17 and a plurality of guide frames 1 are arranged here.
For the receiver with 4, the stand 10 is the link piece 15 and the connecting pin 1
8.19, the entire body is assembled in a restrained state as if it were a chain.

The elongated hole 16 of the link piece 15
It is for moving 0 mutually in an expanded shape,
The movement clearance S is, for example, about 3 inches, and the support is set so that a corresponding interval space L is opened between the products M placed on the table 10.

It is conceivable that the connecting pins 18 and 19 can be inserted and removed freely, but in FIG. A plurality of parallel-connected product holders are assembled as a whole into one unit body A, and the product M
According to the change in the cutting thickness T, the entire chain-like unit body A is to be replaced with a separately prepared unit body.

In that case, the guide frame 14 and the locking hole 13 of the support in another chain-like unit body may vary in size, but the width W of the stand 100 may be changed.
Of course, since they are the same, they can be attached to the guide rail 3 or the locking claw 8 as they are.

In the above configuration, when expanding the panel products M, the plurality of supports in the connected state shown in FIG.
upward, so that the seam matches the cut surface of product M,
A plurality of cut and divided products M are placed and the end locking claw 8 of the expansion arm 7 in the tension mechanism 4 of the installation frame 1 is placed.
After inserting and locking the receivers located at both ends into the locking holes 13 opened in the tabs 12 of the base 10, the expansion arms 7 are operated, and the receivers are moved in the connecting longitudinal direction of the base 10. It is sufficient to forcibly pull the chain-like unit body A from both ends so as to move and tighten the entire chain-like unit body A.

Then, due to the movement clearance S set in the elongated hole 16 of the link piece 15, the joint between the bases 10 will be the seventh
The opening is opened as shown in the figure, and a constant space L corresponding to the clearance S is maintained between the products M on the table in an expanded shape.

In this case, the support forming one end of the chain unit body A is the stand 10.
As mentioned above, the remaining supports may be pulled to move and tension the stand 10 from the other end, but preferably, the total number of stands 10 is an odd number, and the supports are placed at the center points where they are parallel. While the receiver holds the base 10 in a fixed state, the remaining receivers move and tension the base 10 from both ends in the longitudinal direction of the connection, and pull it equally in opposite directions.This method allows for a smoother expansion action. You can expect to see improvements in work efficiency and work efficiency.

Of course, it is also possible to lock the expansion arm 7 to the link piece 15 and pull it to move and tension it in the same way.

Next, FIGS. 8 and 9 show a first modification corresponding to FIGS. 6 and 5 of the above basic example. long hole 1
6 and the connecting pin 18 that passes through it, an elongated groove 16 is provided in one of the adjacent link pieces 15a that are arranged in parallel.
A is opened, and the locking snowflake 18a, which is also protruded from the other piece 15a, is inserted into and engaged with the recessed groove 15a so that it cannot be separated during movement, and the recessed groove 15a provides the above-mentioned movement clearance S. The pieces 15a may be further assembled and connected to the pedestal 10 with the guide frame 14 using separate connecting pins 21.

Also, FIG. 10 shows a second modified example corresponding to FIG. 7 of the basic example, in which the guide frame 14 is omitted and the link piece 15b is attached to the back side of the pedestal 10 by welding or the like. , are directly fixed and integrated, and the protruding ends of the adjacent holders are also connected in a chain shape to the base 10 by bolts 18b and nuts passed through the elongated holes 16b of the piece 15b. ing.

In this case, the straightness of the tube during movement of the stand 10 is guided and maintained by fitting the rail 3 and the receiver into a part of the stand 10, as illustrated in FIG.

Furthermore, as shown in the third modified example of FIG.
is integrally protruded, and its protruding tip is attached to the other support plate 1.
0 and Pole N8c and a nut, and a long hole 16c in which a movement clearance S is maintained may be opened in the piece 15c.

In addition, although not shown, a protrusion, which replaces the connecting pin 18 that passes through the elongated hole 16 of the basic example, is provided to protrude upward from the guide frame 14 and fit loosely into the elongated hole 16. In other words, the plurality of product holders can be connected by loose connecting elements such as the above-mentioned pins and bolts and elongated holes for receiving them, or protrusions and elongated grooves for inserting their holders, etc. As long as the entire structure is assembled and restrained in a chain-like manner and has a movement clearance S for subsequent tensioning,
This can be appropriately adopted in the present invention.

The remaining configurations in the various modified examples described above are substantially the same as those in the basic example, so FIGS.
Only the common reference numerals with those in FIG. 7 are written, and detailed explanation thereof will be omitted.

As described above, in the present invention, as a method of providing a certain interval space L necessary and sufficient for smooth passage of steam between ALC panel products, a certain movement clearance S corresponding to the desired interval space L is provided. A plurality of product holders connected in parallel in a restrained manner like a chain while maintaining the holder 10 are forcibly pulled from both ends or one end in the longitudinal direction of the connection so as to move and tension the table 10 according to the 8 minute play. Because of this, it is possible to stably secure a constant space L at all times, and by expanding the space L, the problem mentioned at the beginning can be completely solved.

In addition, if the tensile force is applied evenly, especially from both ends in the longitudinal direction of the connection, the above movement tension can be completed immediately, and the space expansion effect will be greatly facilitated. 10 are assembled and connected as a chain-like unit body A, even if the thickness T of the product M changes in size, you can simply prepare several sets of unit bodies A according to this in advance, and the unit can be easily changed. The body A can be replaced and installed in about 1 to 2 minutes, and its handling is simple.

Also as a space expansion device, in the configuration of the present invention, the guide rail 3 and the supports movably mounted in parallel along the guide rail 3, a plurality of stands 10, and a plurality of link pieces 1 also arranged in parallel.
5, 15a, 15b.

15c, its cradle and piece 15゜15a,
Each of 15b and 15c is a common pin and long hole,
Alternatively, the tension mechanism 4 is assembled and restrained in the overall chain shape by loose connecting elements such as protrusions and long grooves, and is forcibly moved and tensioned from both ends or one end in the longitudinal direction of the connection. Since the chain-shaped support is also equipped with a stand 10 on the rail 3 and tensioned by hydraulic pressure or mechanical force, it will automatically create a constant space L between the products M. It can be expanded and is ideal for mass production of ALC panel products.

In particular, if the configuration of the basic example described above is adopted, the straightness of the platform 10 can be ensured by the guide frame 14, and the link piece 15 can also be smoothly moved within the guide frame 14, and the chain can be moved smoothly during tension. This can be said to be an extremely effective invention, as it is possible to immediately achieve tension throughout the entire body, resulting in a more practical device.
