Description

Anti-sagged melamine acoustic panel unit for ceiling and wall and method constructing the melamine acoustic panel unit to ceiling and wall}

The present invention relates to a unit structure for preventing wall sagging and ceiling sag integrated melamine sound absorbing material, and a method for constructing walls and ceilings using the same.

Melamine sound absorbing material is a synthetic foam of melamine resin is a collection of fine pores made of an open cell (Open Cell) structure. Melamine sound absorbing material is excellent in sound absorption, non-flammable non-burning in the case of fire, and especially light weight has the advantage of easy installation. It is widely used as sound absorbing material for wall finishing and ceiling in indoor storage, gymnasium, broadcasting station, and multipurpose indoor space.

The shape of a sound absorption material is a square plate shape normally.

The sound absorbing material unit structure of the present invention can be used in a dry space, a humid space such as a swimming pool, a concrete wall, or a ceiling, and it is also possible to precisely construct a pattern, and even a non-skilled worker can be easily and firmly constructed. It is a technical field.

BACKGROUND ART Various types of sound absorbing materials for walls and ceilings such as indoor storage rooms, gymnasiums, broadcasting stations, and multipurpose indoor spaces are commonly used. Melamine sound absorbers or polyurethane sound absorbers, polyester sound absorbers, polyester styrene absorbers and the like. Since the sound absorbing material is formed by a foam, the function and properties of the sound absorbing material are almost similar.

For convenience of description in the present invention will be described mainly for the melamine sound absorbing material of the square plate, but because the melamine sound absorbing material having the same installation concept as installing on the wall and ceiling, both the polyurethane sound absorbing material and similar sound absorbing materials belong to this.

The plate-like melamine sound absorbing material is a sound absorbing material and at the same time a finishing material for concrete walls. Finishing materials should maintain a vertical level on the concrete wall, be firmly attached, and at the same time easy to attach. This requirement holds true for the ceiling as well.

Melamine sound absorbing material is a synthetic foam of melamine resin is a collection of fine pores made of an open cell (Open Cell) structure. Melamine sound absorbing material is excellent in sound absorption, non-flammable non-burning in the case of fire, and especially light weight has the advantage of easy installation. Disadvantages are that the sound absorption by the micropores is the main function is not having its own supporting strength and tearing well. Since it does not have its own supporting strength, it is impossible to install it independently on concrete walls or ceilings. There is a need for a separate support to support it.

When used for concrete walls, there is a wall that can support the melamine sound absorbing material, which can prevent sagging.However, when used for ceiling, there is no strength to support the self-weight of the melamine sound absorbing material. There must be a means.

This will be described by dividing it into a case of using the concrete wall and a case of the ceiling.

1) In case of installing melamine sound absorbing material on concrete wall

Since melamine sound absorbing material is the finishing material of concrete wall, the melamine sound absorbing material should be installed while maintaining the wall vertically, so that the pattern of sound absorbing material is elaborate and the appearance is beautiful. However, concrete walls are not vertical enough to install sound absorbers. To make a vertical plane, you usually need to finish it. Finishing is the creation of the vertical surface of the wall. Finishing is usually done with cement mortar or plywood or gypsum board.

It is divided into a method of installing a melamine sound absorbing material by forming a vertical surface of plywood or gypsum board, and a fabric method of forming a vertical surface of cement mortar and installing a fabric sound absorbing material.

Melamine sound absorbing material installed on the concrete wall is supported by the concrete wall and firmly supported by adhesive or support, so it does not affect the wall pattern due to the deflection phenomenon. In the case of the ceiling, however, the melamine sound absorbing material does not have strength enough to beat its own weight, causing a large deflection. When the sound absorbing material contains moisture, this sagging phenomenon is severely generated and there is a high risk of falling down. For this reason, melamine sound-absorbing material is used only in a small space in the drying space on the ceiling.

 end. Supporting method by plywood or gypsum board (10)

The support method 10 by plywood or gypsum board is a method of forming the vertical surface of the concrete wall C by the plywood or gypsum board 14.

In order to install the plywood or gypsum board 14, first, an under floor support beam 12 is installed in a lattice form on the concrete wall C. The plywood or gypsum board 14 is installed thereon, and then the melamine sound absorbing material M is installed on the plywood or gypsum board 14 by the adhesive 16. [See Fig. 1]

The problems with this approach are listed below.

  A) construction problems

   ⒜ In order to bond melamine sound absorbing material (M), plywood or gypsum board 14 should be installed first.

The size of plywood or gypsum board 14 currently used is usually 120 cm x 240 cm.

Plywood or gypsum board 14 of this size is too heavy. It also has to be raised high above the wall, so it is not easy to handle and difficult to install. There is a problem that construction is inefficient because it is not easy to handle.

   (2) Melamine sound-absorbing material (M) is bonded to the plywood or gypsum board 14 by drawing the joints of the vertical and horizontal. The adhesive 16 should be applied to the front of the melamine sound absorbing material (M). In this state, it is virtually impossible to precisely fit the joints of the aspect. Sophistication is necessary to fit the joints of both sides. If there is a slight error in such sophistication, there is a problem in that as the enlarged to the whole wall adversely affects the pattern of the wall to damage the appearance.

If sophisticated construction is carried out in order to precisely fit the melamine sound absorbing material (M) to the joints of the vertical and horizontal, there is a problem that the workability according to the working time is inefficient because it takes too much time.

On the contrary, if the tolerance of the vertical and horizontal lines is allowed to improve the efficiency of construction, it is only a small error at the starting point of adhesion, but the error is gradually increased when it is expanded to the whole wall. This deviates or twists and the appearance is not beautiful. In this way, if the precise construction is not made in terms of the pattern, there is a problem that the appearance is greatly damaged due to the pattern of the wall.

Melamine sound absorbing material (M) is installed in the concrete wall (C) of the multi-use facility, such as gymnasium, indoor swimming pool, performance hall, theater, hotel, meeting room, and so on, even more so.

  B) process problems

The work process is complicated because the joist 12 is first installed on the concrete wall C, and then the plywood or gypsum board 14 is installed thereon, and then the melamine sound absorbing material M is attached thereto using the adhesive 16. Construction is inefficient and uneconomical

 I. Fabric method

The fabric method 20 is a method of reinforcing the support strength of the melamine sound absorbing material (M) wrapped around the plate-shaped melamine sound absorbing material (M). The fabric 22 is a woven fiber made of melted acrylic and drawn into long fibers and is made of a material such as a sofa cloth.

However, even if the melamine sound absorbing material (M) is given some degree of support strength by the fabric 22, it is not able to be independently supported on the wall (C) by itself. This lack of strength, which cannot stand independently during construction, is reinforced by a plastic joiner 24. The plastic joiner 24 is installed vertically and horizontally to support the fabric sound absorbing material 26 while maintaining the elaboration of the pattern. [See Fig. 2]

The problem with this method is as follows.

  A) Construction and process problems

Since the fabric method 20 is a method of finishing the concrete wall C with a plastering surface to form a vertical surface and supporting the fabric sound absorbing material 26 by a plastic joiner 24 installed in a lattice shape thereon, in terms of patterns, Compared to the support method of plywood or gypsum board 14, there is an improvement, but the process of finishing the concrete wall (C) in the vertical plane, the process of wrapping the melamine sound absorbing material (M) with the fabric 22, and the plastic joiner ( 24) installation process must be required and the work of wrapping the melamine sound absorbing material (M) with the fabric 22 is not only cumbersome, but also the complicated work process of the joiner 24 is not easy and the work time is complicated and the work process is complicated. The work is inefficient and uneconomical.

In addition, if the finishing of the concrete wall (C) does not form a vertical surface as a whole or in part, the vertical surface must be formed separately from plywood or gypsum board 14 to maintain the pattern, so that the fabric sound absorbing material 26 and plastic joining process In addition to the process of you 24, the process of plywood or gypsum board 14 is added, so that the work becomes inefficient and inefficient overall.

2) When installing melamine sound absorbing material (M) on the ceiling

In the case of installing the melamine sound absorbing material (M) on the ceiling in a dry indoor space without moisture is the same as the installation of the wall (C). However, even if the melamine sound absorbing material (M) is installed in a dry indoor space has been limited. The reason is that the melamine sound absorbing material (M) has not solved the sag problem because it does not have the strength to withstand its own weight.

This is why the current melamine sound absorbing material (M) is not installed in the ceiling of the humid pool.

The maximum size of melamine sound absorbing material (M) used for ceiling of dry indoor space is 60cm x 60cm T = 2.5cm or more. Melamine sound absorbing material (M) is a standard that can support its own weight. When the aspect ratio exceeds this standard, a sag phenomenon occurs and it is impossible to use it.

There is a need for a separate reinforcing means that can prevent sagging of the melamine sound absorbing material (M).

On the other hand, can the melamine sound absorbing material (M) of 60cm x 60cm T = 2.5cm size that can be used in the dry space be used for the ceiling of humid indoor space such as swimming pool? The question arises.

When the melamine sound absorbing material (M) of 60cm x 60cm T = 2.5cm contains moisture, the weight of the melamine sound absorbing material (M) cannot withstand its weight and sag occurs. The greater the deflection, the greater the risk of falling down. In fact, melamine sound absorbing material (M) is rarely used in the ceiling of the swimming pool because of the risk of falling.

Even if a melamine sound absorbing material (M) having a size of 60cm x 60cm T = 2.5cm can be installed on the ceiling, the larger the size is, the better it is in terms of economy and workability.

The object of the present invention is to form a unit structure of a plate-shaped melamine sound absorbing material having a maximal standard of efficient construction while precisely installing the plate-shaped melamine sound absorbing material, and to be used for walls and ceilings even in a humid pool or rainy season. It is another purpose to form a plate-like melamine sound absorber unit structure that can be used without limitations if it is a standard that is efficient for construction, and it is a plate-like melamine sound absorber unit that does not sag at all even when installed in a humid rainy season or a swimming pool. Another purpose is to form a structure, and the other purpose is to have a beautiful aesthetic by keeping the pattern constant by the plate-shaped melamine sound absorber unit structure which can be precisely constructed, and the plate-shaped melamine sound absorber unit structure has a reinforcement plate structure. Integral with melamine sound absorbing material As the unit screen by the weight of the lightweight construction is to be effective, economical and easy to handle is in use, there is another purpose.

The plate-like melamine sound absorbing unit structure of the present invention can be used in a dry space, in a humid space such as a swimming pool, or in a concrete wall or ceiling, and it is also possible to precisely construct a pattern, and it is easy to install even in an unskilled worker. The construction is made to be done.

Referring to the plate-like melamine sound absorbing material unit structure of the present invention in detail.

The plate-like melamine sound absorbing unit structure of the present invention, whether used in concrete walls or ceilings, is a structure that is precisely constructed, and even if unskilled workers are easy to construct and can be firmly constructed without sag, the unit structure is of the same concept. Structure.

For convenience of explanation, it will be divided into walls and ceilings.

1) Plate-shaped melamine sound absorber unit structure 100a used for concrete wall (C)

 end. Plate-shaped melamine sound absorbing material unit structure 100a

  판 The plate-shaped melamine sound absorbing material unit structure 100a is composed of a plate-like melamine sound absorbing material 110 and a reinforcing plate structure 120, as shown in FIG. 3, and the reinforcing plate structure 120 and the plate-shaped melamine sound absorbing material 110 which are both members. ) Is the same size, the reinforcing plate structure 120 formed on the back is formed with a reinforcing plate protrusion 122 protruding by d up than the plate-shaped melamine sound absorbing material 110, the plate-shaped melamine sound absorbing material 110 formed on the front ) Is a configuration in which the sound absorbing material protrusions 112 protruding downward from the reinforcing plate structure 120 are formed while the contact portions of both members are firmly adhered with the adhesive 127.

The reinforcing plate structure 120 is sufficient to have a light weight while having a supporting strength as a strength support material.

Honeycomb box 123 is a lightweight and excellent support strength. Honeycomb box 123 is the most preferred material as the reinforcing plate structure (120).

However, a material such as thin plywood or similar materials may be used as the reinforcing plate structure 120.

The reinforcement plate structure 120 is a structure in which the aluminum foil 124 or the flame retardant vinyl 125 is sealed. In order to prevent moisture from penetrating the reinforcing plate structure 120, the supporting strength of the reinforcing plate structure 120 is maintained as it is.

  ⒝ The reinforcement plate structure 120 is a structure sealed with aluminum foil 124 or flame retardant vinyl (125). In addition, by adhering the plastic net 126 having a mesh of 0.5 mm or less on the front and rear surfaces thereof, the fixing and holding force of the staple 132 is reinforced. The load of the plate-shaped melamine sound absorbing material unit structure 100a is completely suspended on the staple 132. And since the plastic mesh 126 surrounds the plate-shaped melamine sound absorber unit structure 100a, the plastic mesh 126 evenly supports the weight of the plate-shaped melamine sound absorber unit structure 100a. Unlike the staples 132 wholly support the self-weight of the plate-shaped melamine sound absorbing material unit structure 100a, since the plastic net 126 shares its support, the fixing and supporting force of the staples 132 is further reinforced.

 I. Different from the prior art

The plate-shaped melamine sound absorbing material unit structure 100a is a unitized unit structure, which is formed in a unit unit structure to facilitate handling by deviating from the method of pasting an adhesive to a conventional plywood. Unlike the prior art, the unit unit structure is a structure in which the reinforcing plate structure 120 is integrally bonded to the plate-shaped melamine sound absorbing material 110, and the reinforcing plate structure 120 is made of the same material as the honeycomb box 123. The aluminum foil 124 or flame retardant vinyl 125 is enclosed and sealed. The installation work is a structure in which the work is completed by directly fixing the plate-like melamine sound absorbing unit structure (100a) to the joist.

Simply by fixing the reinforcing plate protrusion 122 of the plate-like melamine sound absorbing material 110 with the staples 132 in a state facing the horizontal joists 130, the pattern and the fixing is made at the same time.

Since the reinforcing plate structure 120 as a supporting material is formed to simultaneously perform the role of light weight and moisture blocking, it is possible to be installed at the same time not only in a humid pool but also in a dry space, and is light in weight, so that the construction is easy and the pattern is easy to fit. There is an advantage that even a skilled worker can be constructed.

In addition, the plate-shaped melamine sound absorbing unit unit structure 100a of the present invention, unlike the fabric method 20, even if the concrete wall (C) does not finish finishing because the horizontal surface joist 130 leveling the vertical plane is efficient construction.

2) Plate-shaped melamine sound absorbing material unit structure 100b used for ceiling of swimming pool

 판 As shown in FIG. 8, the plate-shaped melamine sound absorbing material unit structure 100b is composed of a plate-shaped melamine sound absorbing material 110 and a reinforcing plate structure 120. In the relationship between the two members, the size of the reinforcing plate structure 120 is While the reinforcement plate structure 120 which is larger than the plate-shaped melamine sound absorbing material 110 and formed on the rear side of the plate-like melamine sound absorbing material 110 is formed in the reinforcing plate protrusion 122 protruding by four directions d, the contact portions of both members are formed. Is a configuration that is firmly bonded with the adhesive 127.

Reinforcement plate structure 120 is the same as the configuration described in the configuration of the wall (C).

That is, the reinforcing plate structure 120 is sufficient to have a light weight while having a supporting strength as a strength support material. As long as the unit unit structure can be formed of a thin plywood or similar material that can play a role.

Honeycomb box 123 is a lightweight and excellent support strength. It is the most preferable material as the reinforcement plate structure 120.

The reinforcement plate structure 120 is a sealed structure surrounded by aluminum foil 124 or flame retardant vinyl 124. In order to prevent the reinforcing plate structure 120 is corroded or damaged by moisture.

 ⒝ Also, the shape of the plate-shaped melamine sound absorbing material 110 is formed by the upper and lower layers 114 and 116, but the lower layer 116 is formed to have the same size as the size of the reinforcing plate structure 120 protruding by four directions d and the upper layer. 114 is smaller than the reinforcing plate protrusion 122 protruding by four directions d, and is a structure of another embodiment in which the reinforcing plate structure 120 and the lower layer 116 are integrally formed by the adhesive 127.

The plate-shaped melamine sound absorbing material unit structure of the present invention unitizes the melamine sound absorbing material and the reinforcing plate structure rule so that the weight is light and easy to handle, so that the construction is efficient and economical.

The plate-shaped melamine sound absorber unit structure of the present invention is a structure that is reinforced to have a maximum standard without sagging by the reinforcement plate structure and the structure of fixing the plate-shaped melamine sound absorber unit structure of the maximum standard directly to the joist, as well as the construction work is simple As the melamine sound-absorbing material unit structure of the plate is fixed to the joist, the pattern is made precisely, so even the unskilled workers can install it easily and the construction is efficient and economical.

Since the reinforcement plate structure is formed as a closed unit that blocks moisture and is formed as a light unit weight structure, it can be used in a humid space such as a dry space, a swimming pool, a concrete wall, or a ceiling.

The support strength of the reinforcement plate structure is large enough to support not only the self-weight of the melamine sound absorbing material in the plate shape but also the weight with moisture, so that it does not cause sagging and deformation even when the walls and ceilings of a space such as a swimming pool are damp. There is.

The present invention is a useful invention in which the pattern of the wall and the ceiling can be kept constant by the plate-shaped melamine sound absorbing unit unit structure, and the appearance is beautifully constructed.
