Detailed Description
Fig. 1, 2 and 3 show a mold for manufacturing a sound absorption plate, which comprises a bottom plate 1, side plates 2, an upper plate 4 and mounting bolts 3.
Fig. 2, 4, 5 show that bottom plate 1 is U-shaped and trilateral opening, and one of them opening upwards places on vibration platform, and two blocks of curb plates 2 are placed in 1 two sides of bottom plate (preceding, two back sides) and with these two side shutoff, and upper plate 4 sets up and fixes through construction bolt 3 on bottom plate 1 and curb plate 2, and bottom plate 1 is equipped with round steel 6, and round steel 6 is used for prefabricating the mounting hole of acoustic baffle.
The bottom surface of the bottom plate is provided with 4 rows of grooves 5 which are arranged in the direction vertical to the side plates at equal intervals, a reinforcing mesh is placed in the combined bottom plate during manufacturing, the upper plate 4 covers the combined bottom plate and the reinforcing mesh, and the upper plate 4 is connected with the stop block 13 of the bottom plate 1 by using the mounting bolt 3 until the upper plate and the bottom plate are screwed down to form a complete sound absorption plate die. The rear side plate 2 is fixed by the extrusion of the upper and lower dies after the bolt 3 is fastened. And finally pouring ultrahigh-strength concrete, vibrating, forming, maintaining and removing the mold.
The bottom plate 1 is a supporting die for manufacturing the sound absorption plate, and the bottom plate 1 is a U-shaped plate consisting of a lower plate, a left plate and a right plate. The bottom plate 1 is provided with 4 rows of grooves 5, the grooves 5 are parallel to the chimbs 9 of the U-shaped groove, the 4 rows of grooves 5 are equidistantly arranged, the grooves 5 (vertical side plate direction, equidistantly arranged), the curve pattern of the grooves 5 is y/a + z/c =1, wherein a =1, c =3, -1 < y < 1, 0 < z < 3, the grooves are used for making sound-absorbing plate surface protrusions, reducing the reflection of the sound-absorbing plate surface. Round steel 6 sets up in the protruding 8 positions of bottom plate 1, and round steel 6 is used for prefabricating the mounting hole of sound absorption face. Four stop blocks 7 are arranged on the two sides of the bottom plate 1 in the direction vertical to the groove, and the stop blocks 7 are provided with threaded holes; the stop dog 7 is used for limiting the side plates 2 on the two sides, so that the bottom plate 1 and the side plates 2 form a complete square-shaped combined bottom plate, and the threaded hole in the stop dog is used for fastening the upper plate 4.
Fig. 4 and 6 show that the side plate 2 is composed of a convex plate 21 with two concave sides in the middle and two sections of side plate round steel 22, the convex part of the side plate 2 is provided with the side plate round steel 22, the side plate 2 is placed on the side of the stop blocks 7 on the two sides of the bottom plate 1 and forms a square-shaped combined bottom plate with the bottom plate 1, the side plate round steel 22 is used for prefabricating connecting holes of the sound absorbing plate and the supporting column, and blind holes are formed in the formed holes for installing bolts.
