Description

[Detailed Description of the Invention] The present invention relates to a soundproof ceiling structure using a soft soundproof sheet.

Soft sound insulation sheets, such as sheets made by mixing soft vinyl chloride compound with heavy metal powder or heavy metal compound powder, have a high areal density and have excellent sound insulation properties despite being relatively thin. By combining it with sound-absorbing materials, excellent soundproofing effects can be obtained, and it has come to be widely used in soundproofing construction.

However, when applying soundproofing to the ceiling,
It is necessary to house the above-mentioned sound-absorbing material in a lattice-like frame formed by the field edge, and to extend a soft sound-insulating sheet in contact with this, that is, on the upper surface of the field edge. In this case, there was a problem with the construction method of the soft sound insulating sheet at the part of the hanging tree that connects and supports the field edge, and a reliable and easy mounting structure with good sound insulation properties was desired. That is, if there is a gap between the sound insulation sheet and the hanging tree, noise will leak and the sound insulation effect will be reduced, so sufficient care must be taken when constructing the space. To give an example of a construction method, for example, a cross-shaped cut is made in the fishing rod part of a soft sound insulating sheet, and the four triangular pieces created by the cut are pushed outward, and the fishing rod is inserted into the square hole obtained. Using this, press the triangular piece mentioned above into tight contact with the side of the fishing tree. However, this construction method is complicated and uncertain, and the conventional nailing method is used to connect the fishing tree and the edge, and large nails are used to reach the deep part of the edge of the field. As a result, the end of the fishing log often cracks due to nailing, and there has been a demand for improvement in the method of connecting the fishing log and the edge.

This invention solves the problem of installing the soft sound insulation sheet on the fishing tree part by using metal fittings that connect the fishing tree and the field edge.The present invention is easy to install and has excellent sound insulation effect on ceiling soundproofing. It provides a structure and also prevents the end of the fishing rod from cracking due to nailing.

To explain the present invention based on the drawings, Fig. 1 is a perspective view of an example of a mounting bracket used in the present invention, in which the mounting bracket 1 is made of a steel plate with an appropriate thickness, a fishing rod attachment part 2, a field edge attachment part 3 and an intermediate constricted portion 4, and each mounting portion is provided with an appropriate number of wood screw holes 5. To install the soft sound insulation sheet using this mounting bracket, as shown in the installation structure explanatory diagram in FIG. Cut a notch 9 about the width of the mounting bracket on the side of the field edge at the corresponding location, insert the mounting bracket 1 into this notch 9 up to the constriction 4, and attach the fishing rod attachment part 2 and the field edge attachment part 3, respectively. Attach the fishing tree to the side of the field edge using the wooden screw hole 10. At this time, the fishing tree 7 is attached with an appropriate distance between the lower end surface and the upper surface of the field edge 8, and the soft sound insulating sheet 6 is spread over the field edge 8 without any trouble by covering the sound absorbing material using this gap. be done.

According to the above-mentioned mounting structure, as shown in FIG. 2, the cut is extremely short, about the width of the mounting bracket, and the cut of the cut 9 is in contact with the constriction 4 of the mounting bracket, and the elasticity of the soft sound insulating sheet prevents the constriction. The area is pressed to maintain a sealed state, and there is no noise leakage, providing excellent sound insulation. Alternatively, you can cut a straight line in the corresponding location of the soft sound insulation sheet, insert the mounting bracket, and fasten it to the fishing tree or field edge with wooden screws, and then fix the required locations of the soft sound insulation sheet to the field edge using an appropriate method. , construction is easy and reliable. In addition, since the mounting bracket and the fishing rod or edge are attached using a plurality of wooden screws, small-sized wooden screws are sufficient, and therefore there is no risk of cracking of the end of the fishing rod. It goes without saying that this mounting structure can be used not only for soundproofing construction, but also for mounting general fishing trees and wild edges.

FIG. 3 shows a perspective view of another example of the mounting bracket,
It is attached to the joint part of the field edge, which is bent at a right angle, and is attached to both sides of the field edge which intersect at right angles, and has the effect of reinforcing the joint part of the field edge. have

Since the present invention has the above-mentioned configuration, the soft sound insulating sheet can be easily installed, the performance of the soft sound insulating sheet can be fully exhibited without fear of reducing the sound insulation effect, and the end of the fishing tree can be prevented from cracking. That is, in the conventional soundproofing construction using gypsum board and sound-absorbing material, compared to the soundproof ceiling structure according to the present invention shown in FIG. It is necessary to stack two tiers of fences 8 for nailing, which lowers the ceiling and creates a feeling of pressure, but in the case of the present invention, as shown in the cross-sectional view of Fig. 4, The field edge only needs to be one step, and unlike plasterboard, soft sound insulation sheets have the advantages of excellent sound insulation, easy construction, earthquake resistance, and water resistance, so there is no risk of damage due to vibrations, rain leaks, etc. .
