[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a partition plate of a form for inserting into a box-shaped form and adjusting the size of the form when, for example, a lightweight cellular concrete (hereinafter referred to as “ALC”) panel is manufactured. is there.
[0002]
[Prior art]
Conventionally, for example, when manufacturing an ALC panel, a rectangular box-shaped formwork 1 having an inner shape length of about 600 cm, a width of about 240 cm, and a depth of about 65 cm generally corresponds to the number of panels. After setting the reinforcing steel bars (not shown), the raw material ALC slurry is injected and foamed.
Then, when the raw material ALC slurry is cured to a semi-plastic state after a desired time has passed, the semi-plastic body is taken out from the mold, and the upper surface is cut to a height of 60 cm. Cut to thickness.
[0003]
Thereafter, this semi-plastic body is charged into an autoclave and steam-cured at high temperature and pressure, and then the outer surface is cut as necessary to form an ALC panel product having a desired thickness. The maximum ALC panel length is 600 cm of the mold length. If a shorter ALC panel is required, it can be cut in the width direction in the cutting process of the semi-plastic, or a long ALC panel product is desired. It is formed by cutting into dimensions or by inserting a partition plate into the mold to adjust the length of the inner shape.
[0004]
In order to adjust the length of the inner shape of the mold by inserting the partition into the mold, for example, as shown in the front view of FIG. 2 is used. This partition plate 2 has a structure in which an iron plate 4 is fixed to a frame obtained by welding angles 5 in a lattice shape, and is screwed in a state in which the plate-like portion is suspended by an angle 6 suspended on the upper edge of the mold 1. Has been. Further, the rotating portions 2a on both sides of the plate-like portion are configured to be opened and closed by cylinders 3 respectively, and when the partition plate 2 is attached to and detached from the mold frame 1, it is opened inside to reduce the width of the partition plate 2. Therefore, the attaching / detaching work is facilitated.
[0005]
Further, as shown in FIG. 8, rubber packings 7 are attached to the three outer edge end surfaces of the lower edge end surface and the both side vertical end surfaces of the partition plate 2 that abuts the inner surface of the mold 1. The outer edge end surface of the material is in close contact with the inner surface of the mold 1 to prevent leakage of the raw material ALC slurry.
Further, as shown in FIGS. 6 and 7, a pair of L-shaped guide portions 8 are disposed at opposite positions on both ends of the upper end of the partition plate 2, and fixing bolts 9 are horizontally disposed on the vertical surfaces thereof. In addition, through holes 8a are drilled at a desired interval in the horizontal plane.
[0006]
On the other hand, reinforcing members 1a are fixed to both sides of the long side of the mold 1. In the longitudinal direction of the upper surface, guide pins 1b that are equidistant from the through-holes 8a and have thin tips are arranged in parallel. A concave portion 1c is provided on the outer surface of the upper edge of the mold 1 at a predetermined interval. When the partition plate 2 is set on the mold 1, the crane (see FIG. 2) is opened from above the desired position of the mold 1 with the both-side rotating portions 2 a of the partition plate 2 opened inward and the width thereof reduced. The guide pin 1b at a desired position is inserted into the through hole 8a of the guide portion 8 and positioned. Next, the horizontal fixing bolt 9 is rotated so that its tip is fitted and fixed in the recess 1c at a desired position, and the rotating portion 2a is closed so that the three outer edge end surfaces of the partition plate 2 are on the inner surface of the mold 1. If they are in close contact, the partition plate 2 is set on the mold 1.
[0007]
Then, a desired number of reinforcing bars (not shown) are set in the mold, and then the raw material ALC slurry is injected and foamed and cured. Then, when the desired time has passed and the resin has been cured to a semi-plastic state, the rotating portion 2a is opened inward, and the fixing bolt 9 is loosened and the partition plate 2 is pulled up and removed. However, since the side surface of the partition plate 2 is in close contact with the semi-plastic body at this time, when the partition plate 2 is pulled up, a part of the semi-plastic body adheres to the partition plate 2 and damages the end portion of the semi-plastic body. There was something to do.
[0008]
Further, as described above, rubber packings 7 are attached to the outer edge surfaces of the three sides of the partition plate 2 in contact with the inner surface of the mold 1, and the outer edge of the partition plate 2 is in close contact with the inner surface of the mold 1. However, since the mold packing 1e is interposed between the bottom plate 1d and the side plate 1f of the mold 1 as shown in FIG. There was also a problem that 1 g of a gap was formed and the raw material ALC slurry leaked out from this gap 1 g.
[0009]
