Description

[Detailed description of the invention] This invention relates to an apparatus for manufacturing soundproof panels.

A conventional soundproof panel made of G, R, and C and having the number of frames 'a=A is known as shown in FIG. However, no equipment has been realized that can efficiently manufacture such soundproof panels with simple operations and therefore provide all products at low cost, and there is a demand for such equipment.

The purpose of this invention is to meet the above-mentioned demands, and furthermore, the number of frames made of KG, R, and C is the bottom plate.

In addition to the side panels, it has an eave plate that protrudes inwardly from the upper end of the side plate, and this allows the internal sound absorbing material to be held in place.
C) 1. What is the manufacturing equipment for the soundproof panel metal whose bending part is reinforced by forming it by bending? In order to achieve the above-mentioned objects, the present invention includes first and second side plates that are in instant contact with each edge of a rectangular substrate and have the same length as each edge, and are arranged so that they can all stand up. 1. A shorter No. 8.4 side plate is pivotally supported on the edge of the second side plate opposite to the substrate edge, and the entire forming form is constructed by extending the protrusions along the free edge of the @8゜4 side plate. The substrate is attached at the center of the support base frame of approximately the same shape located below it, and 7)

This receiving plate 22 is supported by a suitable support (not shown).
@18, removably mounted on 18'.

The manufacturing Ik assembly assembled as described above.

It can be detachably attached to a vibration table (not shown).

The process of manufacturing one example of the soundproof panel shown in Figures 11-18 using the above-mentioned apparatus will be explained with reference to Figures 8-10.

Apply a release agent to the entire surface of the molding frame 1 and the receiving plate 22 that have been developed as shown in Figure 8. A glass net 87 is laid on top of the mold release agent, and a feeder (not shown) is placed on top of it. A large number of crow short fibers approximately 2 cm in length are uniformly mixed in an almost horizontal direction,
Sheet-like G and R having a constant width and a thickness equal to the height of the protrusions 8 and 8'.

C mortar 31 is continuously added to create a state as shown in the fourth figure. At this time, the glass net 87 may be omitted if necessary.After this, a perforated plate of an appropriate amount not shown above and an appropriate amount of metal are placed on the surface of the G, R, C mortar 81. , rji installed below the support base frame 11
The mortar on the molding frame is removed by V vibration using a vibration source such as a sound table wave vibration motor. [Sl, remove the perforated plate and weight after finishing the cutting.

At this time, in the case where the class net 87 is laid as described above, the glass net 87 may be damaged due to vibration.
, R, C will be buried inside the mortar.

As shown in temporary No. 5I24, the receiving plate 22 is removed together with the mortar on it, and a sieve with a height of 3°8'i4.4' of the side plate is placed on the mortar in the part corresponding to the substrate shown by the chain line. A sound-absorbing moon 32 made of an appropriate material is placed on the corner part, which is slightly lower than F and has an isosceles triangular notch r with two sides #1 equal to the height of the front bC side plate.

Glass net 85 (Figure 11) on top of the sound absorption 182? Further, as shown in Fig. 6, punch metal 88 made of SUS was attached to cover the upper surface and 5 sides of the 4 sides of the mounting 2.

This metal 38 upper part 41Q4 has sound absorption, lJ'82
A through hole 84 is provided at a position 1K corresponding to the notch.

Net 85 may be omitted if necessary.

Then, as shown in FIG. 7, the first side plates 8, 8'.

The second side plate 4.4"k is raised in sequence, and this raising action is performed by sequentially moving the first supporting member 1111.fill and the second supporting members 14 and 14' upward in FIG. Then, using a holding member (not shown), the first.
Hold the second side plate in this state.

The side plate 42 (FIG. 12) of the frame plate 86 is formed on the outside of the measuring part metal 88 by this operation.
Combines with 8.

After that, as shown in Fig. 8, the third and fourth side plates 5゜5'+6
．． 6' to the internal force in J order, and by this operation, the eave plate 48 of the frame plate 86 is attached to the same edge of the top metal 88 (Fig. 12).
is formed, and the tongue of the interior member is held by this eave plate 48.

As shown in detail in Figure 9, the locking tools 2B, 2B' are provided near both edges of the same plane of the first and second side plates.
￥L Both side plates 8', 4' have the same VC bell, connecting tool 250 with 7 parts extending horizontally above the through hole 84, both hanging leg pieces 24
, 24' are fixed by fasteners such as bolts (not shown), and this connector 25 prevents the side edges of both side plates from warping and opening. A branch piece 26 is provided protruding from approximately the center of the horizontal part of the joint 25 to the same corner, and a hollow cylinder 27 as shown in FIG. 10 is fixed to the back surface of this branch piece 26. A bolt 28 is inserted into the hole communicating with the 27 hollow cylinders, and an embedded nut 29 is screwed into the lower part of the I-seat 28.

The lower end of this embedded nut 29 is widened towards the end, and its half shape is polygonal.91stly, the corner member 80 is for forming the upper surface of the corner part of the soundproof panel. No isosceles triangle t, punching metal 88
It is placed on top, and both sides thereof are in contact with the edges of the eighth and fourth side plates.

After that, G and R are inserted into the corner space from the through hole 84.

Fill the first and second side plates of C mortar to a height of 1.

Thereafter, the whole manufacturing apparatus is separated from the shaking table and sent to a curing chamber, the mortar is hardened by steam curing, and the mold is broken out to form a soundproof panel as exemplified in Ill-1B.

When warming up, remove the two nuts 28 from the embedded nuts 29 that are integrally embedded in the corners of the frame plate 86,
Thereafter, the screw hole of this embedded nut 29 is used as a bolt hole used for lifting or attaching the product. Note that this soundproof panel is just one example, and it goes without saying that other soundproof panels can be manufactured using this apparatus.

The present invention is as described above, and the first and second side plates are vertically disposed adjacent to the edge of the substrate.

Further, an 8th and 4th side plate is pivotally supported on the edges of the first and second side plates so as to be able to stand up, forming a molding frame, and the substrate of such a molding frame is attached to the support base frame.

In addition, the 2nd side plate is the 1st 2nd side plate pivoted on the support base frame.
The supporting members, some of which are fixed to the 1st and 2nd side plates, are supported by the support base frame, and the free edges of the 8th and 4th side plates are provided with protrusions.
fff41, erecting the 2nd side plate.

By rotating the 8th and 4th side plates, a single mortar sheet can be used to create as many bottom plates, side plates, and frames of the soundproof panel.

Since the eaves plate is automatically formed and expanded, the soundproof panel can be manufactured efficiently.In addition, each part of the bottom plate, side plate and eaves plate is formed into an integral sheet shape.

Since it can be cast with C mortar, the bent part is extremely strong compared to conventional panels that are made into one piece by sequentially filling the bottom and side panels. It is suitable for mass production because it can be accomplished by simple operation of the second support member.

Another effect is that the product can be provided at a low price.
