ある。(Means for Solving the Problems) The present invention involves setting a large number of independent reinforcing wire meshes vertically within the same formwork with the spacing between the reinforcing wire meshes within 37 mm, and pouring lightweight aerated concrete slurry into the formwork. When manufacturing lightweight aerated concrete panels with a thickness of 37 mm or less by curing and semi-curing, cutting into many panels and curing in an autoclave, the slurry temperature at the outer edge of the formwork is lower than that of the lightweight aerated concrete slurry. The lightweight foam is characterized by controlling the position of the reinforcing wire mesh by heating the outer edge of the formwork to a temperature range 15°C to 20°C higher than the slurry temperature in the center when injection into the formwork is completed. This is a method for controlling the position of a reinforcing wire mesh during the production of a concrete panel precursor.

There is a need to. If the temperature is lower or higher than this range, the reinforcing wire mesh will be displaced. The temperature of the slurry in the center when the lightweight aerated concrete slurry is poured into the formwork will vary depending on the slurry raw materials, but in most cases the temperature will be between approximately 40℃ and 50℃. shows.

が極めて少なくなる。(Function) The heating temperature at the outer edge of the formwork is such that the slurry temperature at the outer edge of the formwork is 15°C to 20°C higher than the slurry temperature at the center when the lightweight aerated concrete slurry has been poured into the formwork. When the temperature is controlled within the range, the displacement of the reinforcing wire mesh becomes extremely small. Even if the temperature is lower or higher than this range, the slurry contains air bubbles, which may cause a large flow from the center to the outside, or a large flow from the outside to the center. , the reinforcing wire mesh will be displaced. Generally, the outer edge of the formwork is provided with an extra edge where there is no reinforcing wire mesh, and this extra edge is removed by cutting with piano wire, so that both sides of the outer product are cut with piano wire. If this extra end is provided, the reinforcing wire mesh in the portion adjacent to the extra end will be greatly displaced, but due to the above-mentioned effect, even the reinforcing wire mesh in the portion adjacent to the extra end can be easily removed by the present invention. When controlled according to the following, the displacement of the reinforcing wire mesh becomes extremely small.

て静置する。 This raw material slurry was held between set rods 1, which served as supports, as shown in FIGS. 1 and 2, and a metal lath 2, which served as a reinforcing material, was held between them so that the mutual spacing l was 37 mm. Note that the initially set distance So from the metal lath 2 on the formwork 3 side is 50 mm. The raw material slurry 4 is injected into the mold 3 in which a large number of metal laths 2 are arranged up to the height of line A shown in FIG. 1 and left to stand still.

As can be determined as Measurements can be made with a non-contact displacement meter 5 that can be electrically and continuously measured using eddy currents attached to the eddy current. The sensing part 6 of the displacement meter 5 protruded 10 mm into the side surface of the mold, and was covered with an acrylic resin plate so that the sensing part 6 did not come into direct contact with the raw material slurry 4. Since the sensing part 6 protrudes 10 mm from the side of the formwork in this way, the distance X between the outermost metal lath 2E and the outermost metal lath 2E that can be sensed by the displacement meter 5 is longer than the distance S between the side surface of the formwork and the outermost metal lath 2E. The value is 10mm less. Therefore, the above-mentioned distance S=X+10 mm.

メタルラスの変位量を上記の手段で測定した。 This heating from the side continued for one and a half hours, with time measurement starting from the time when the raw material slurry was injected to the height shown by line A, after which heating by the heating element was discontinued. In addition, the set rod 1 is used to transfer the raw material slurry to A.
After 40 minutes from the time of injection to the height shown by the line, it was removed and experimented. In addition, in the end, it becomes a lightweight aerated concrete block with the height of line B shown in Figure 1.
After 1 to 2 and a half hours have elapsed after the heating element was de-energized, when the hardness reached 30, which is suitable for the cutting process using piano wire, the mold was removed from the mold and cut into the specified shape. It was cut into panels of 37 mm thickness and cured in an autoclave. In the process of manufacturing panels in this manner, the amount of displacement of the metal lath in the formwork was measured by the above-mentioned means.

The outer edge of the formwork is heated to a temperature range of 15℃ to 20℃ higher than the slurry temperature in the center when the lightweight aerated concrete slurry is finished pouring into the formwork, and the reinforcing wire mesh is heated at the outer edge of the formwork. A method for controlling the position of a reinforcing wire mesh during the production of a lightweight aerated concrete panel precursor.
