Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a sound-insulating fireproof partition wall structure constructed using fireproof panels.

0002

[Prior Art] Conventionally, a general sound-insulating and fire-resistant partition wall structure has been constructed by attaching frames such as lightweight steel bases or studs at regular intervals to runners attached to the ceiling and floor. This method involves attaching fire-resistant panels from both sides and inserting sound-absorbing material between the two fire-resistant panels, or using self-supporting panels and panels without using lightweight steel foundations or studs. It was built using the self-supporting construction method.

0003

[Problems to be Solved by the Invention] However, the sound insulating partition wall structures constructed by such a furring base construction method or a self-supporting construction method have the following drawbacks.

[0004] Furnace base construction method: There is a standard for determining fire resistance performance, in which the average temperature of the furring edge is 400°C or less and the maximum is 500°C or less in a prescribed fire resistance test (JISA-1304). Since the rim exists inside the partition wall, the facing material is required to have fire resistance performance that satisfies this standard by substantially covering only one side of the rim. In addition, in the impact test in the fire resistance test, after heating for 2 hours, a 10 kg shaped weight was dropped from a height of 1 m onto the test surface to detect cracks that reached the hollow layer where the shell rim was located. It is required that this does not occur. In order to satisfy these two conditions,
The facing material on one side of the rim must have both fire-resistance and shock-resistance properties, so it must be quite thick, or it must be made impact-resistant by covering the back side or inside of the facing material with lath, wire mesh, etc. Performance must be increased.

Regarding sound insulation performance, since the front and back side materials are directly attached to the rim, the rim forms a "sound bridge", and the sound insulation performance can be obtained even if sound absorbing material is inserted into the hollow part. has its limits.

In terms of wall rigidity, there is an advantage that the facing material can be made of a relatively thin material in order to maintain rigidity against in-plane and out-of-plane deformation by the furring base being integrated with the facing material. This advantage cannot be fully utilized in order to ensure the above-mentioned fire resistance performance and sound insulation performance. In addition to the above-mentioned drawbacks, the furring base construction method requires a process of assembling the base, which increases the construction period and costs.

[0007] Freestanding construction method: Since there is no shell edge, the criterion for fire resistance testing is the temperature of the back side opposite to the heating side (260
℃ or less). In addition, in the impact test in the fire resistance test, it is sufficient as long as there are no holes that reach the back surface. Therefore,
Both double-sided and single-layer panels can be said to be construction methods that relatively easily provide fire resistance.

Regarding sound insulation performance, in the case of a single layer,
In order to obtain the necessary sound insulation performance as sound propagates through solid materials, extremely thick walls are required, or measures such as installing a vibration layer inside the face material are required. becomes.

On the other hand, in the case of double-sided cladding, the hollow layer can prevent solid sound from propagating, and the necessary sound insulation performance can be obtained with a relatively thin panel structure. In addition, by inserting sound absorbing material into the hollow layer, higher performance sound insulation performance can be obtained.
Judging from the perspective of sound insulation, it can be said to be an advantageous construction method.

[0010] Regarding wall rigidity, the facing material itself must have the necessary rigidity against external forces in both single-layer and double-sided walls. For this reason, the thickness of the facing material is often increased, which increases the weight of the facing material, and the workability during transportation and construction becomes extremely poor. In the case of double-sided panels, there is a method of integrating the ribs and ribs with the facing material in order to maintain the rigidity of the facing material, and this can be said to be a good method in terms of providing rigidity without increasing the weight too much. However, in a panel in which the ribs and ribs are integrated with the face material in advance, the total thickness of the panel increases by the amount of the ribs and ribs, which deteriorates the efficiency of transportation. Moreover, cutting workability becomes poor at the portions of the ribs and ribs. On the other hand, when attaching stiffeners and ribs to the facing materials at the construction site, the work becomes complicated, which not only increases the burden on the workers, but also causes problems such as lengthening of the construction period and deterioration of the accuracy of the installation work. arise. In addition to the above, in the case of a single-layer partition wall, there is a further drawback that electrical wiring and piping cannot be installed inside the partition wall.

Furthermore, a common drawback is that conventional sound-insulating fireproof partition walls generally use ceramic materials such as asbestos slate boards, calcium silicate boards, fiber gypsum boards, gypsum boards, and extruded boards as facing materials. However, these materials cannot be expected to hold screws as well as wood or metal. For this reason, when attaching hooks, shelf boards, etc. to partition walls, it is necessary to install a reinforcing plate with screw holding power on the back of the mounting part in advance, or to devise some kind of device to increase the holding force of the jig itself. It is necessary to use a dedicated fastening jig.

[0012] Therefore, the object of the present invention is to solve the drawbacks or problems in the conventional art by providing a lightweight fireproof panel constructed by attaching a fireproof panel made of a fireproof plate lined with a metal plate to an upper runner and a lower runner. The object of the present invention is to provide a sound-insulating, fire-resistant partition wall structure.

[0013]

[Means for Solving the Problems] In order to achieve the above-mentioned object, according to the present invention, a sound-insulating fireproof partition wall structure includes a fireproof panel consisting of a fireproof plate lined with a metal plate, an upper runner and a lower runner. It is characterized by being lightweight, with sound-absorbing material inserted between both fireproof panels.

[0014] In addition, the sound insulating fireproof partition wall structure of the present invention uses a fireproof panel in which a metal plate is lined with a fireproof plate, and a metal plate is attached to the lower runner or upper runner installed on the floor slab surface and the lower surface of the ceiling slab or the lower surface of the beam. The walls are constructed by attaching the panels so that they are on the inside. At this time, a furring base such as lightweight steel base studs is not used. Furthermore, to further improve fire resistance, sound insulation performance, and rigidity, it is possible to add plates made of ceramic materials to the surface of fireproof panels, and when inserting sound absorbing materials inside partition walls for the purpose of sound insulation and heat insulation. It can also be used to hold the sound absorbing material in place by bending and raising the "U" or "V" shaped notch provided in advance on the metal plate on the back of the panel and inserting this protrusion into the sound absorbing material. .

Furthermore, in the sound-insulating and fire-resistant partition wall structure of the present invention, the rigidity of the entire fire-resistant panel is greatly increased by the metal plate bonded to the back surface of the fire-resistant plate of the fire-resistant panel, so when used as a partition wall, It has sufficient load-bearing performance against applied out-of-plane forces, in-plane forces, and impact forces, and the amount of deformation caused by these external forces can be kept small. In addition, since the total thickness of the fireproof panel is just the thickness of the facing material and the thickness of the metal plate, the thickness of the entire partition wall can be made thinner, and the thickness of the entire fireproof panel can be reduced by using the metal plate. Due to the increased rigidity, there is no need to provide a furring base, and as a result, both sides of the partition wall are acoustically and thermally insulated, resulting in excellent sound insulation and fire resistance performance, and the completion of the partition wall. The number of work steps required up to this point is reduced, and the construction period can be shortened. Furthermore, since a metal plate is provided on the back side of the fireproof panel, the screw holding force is extremely strong, and there is no need to provide a reinforcing plate at the screw fastening part or use a special fastening jig.

Furthermore, since the sound-insulating fire-resistant partition wall of the present invention does not require a furring base, a sound-absorbing material for increasing sound insulation and heat insulation properties can be inserted into the partition wall without any gaps over the entire wall surface. By bending the U-shaped or V-shaped notches in the metal plate on the back of the fireproof panel and sticking the sound-absorbing material into these to hold them in place, work efficiency during partition wall assembly can be improved, and the partition wall can be completed. The sound-absorbing material does not slip down even after installation, and the initial performance of sound insulation and heat insulation can be maintained for a long period of time.

Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

When installing the sound-absorbing material 9 by inserting it into the hollow layer of the sound-insulating fireproof partition wall structure 1, as shown in FIG. The sound absorbing material 9 can be held by piercing. In this way, by piercing the sound absorbing material 9 with the protrusion 6, the sound absorbing material 9 is fixedly held inside the fireproof panel 2 without falling off. Therefore, by attaching such a sound absorbing material 9, the workability during assembly of the sound-insulating fireproof partition wall structure is improved, and the initial performance can be maintained for a long period of time even after the sound-insulating fireproof partition wall structure is completed.

[0026] As a result, the adjacent panels are firmly joined together, and the in-plane force and out-of-plane force applied to the wall surface can be transmitted to the entire wall surface, resulting in a more durable partition wall. Furthermore, compared to a method using a joiner or the like, the number of members constituting the partition wall can be reduced, improving work efficiency and at the same time having the effect of preventing unevenness.
