Description

A structural block to keep adi abatic and to prevent noises, and a method

The present invention relates to a structural agent having a function of eliminating vibration between floor insulation and sound insulation or sound absorption of a building, and in particular, it is manufactured in a plate shape to provide excellent thermal insulation performance, sound insulation as well as sound absorption, and economical and ease of construction. It relates to a structural agent and a method for producing the same.

In order to remove the vibration sound generated between the floors in the current multi-storey building, the sound between the floors and the sound absorbing must be made at the same time as the vibration is transmitted by the impact.

However, sound insulation is a simple blockage of sound transmission, so the higher the mass per unit area or the higher the frequency of sound, the greater the degree of sound blockage, and sound absorption is usually used to reduce noise in the room. The air in the hole is mainly made of porous material so that the air is vibrated by the sound waves of the noise, and the resulting friction causes the sound energy to be converted into thermal energy, thereby absorbing it.

However, the noise between floors is a phenomenon that occurs when the vibration sound transmitted from the upper floor is moved to the lower floor, which produces the best effect when the porous material is exposed to the outside, but in the structure between the floors of the building, it is exposed to the outside. Impossible is to use a panel with pores to remove the vibration sound.

Therefore, various panels having such pores are used, but the disadvantage of these is that a separate insulation construction is required, and if you want to construct a panel having such pores and styropol for insulation at the same time, it is effective by the use restriction of these structural agents. Appropriate construction for insulation and noise reduction is required.

In addition, even in such construction, there are many problems in removing vibration sound as well as a problem of heat insulation.

Therefore, sound insulation and sound absorption are simultaneously performed by using an elastic body (such as styropole) having an air layer at the same time as the sound insulation, but the air layer is in an independent state, and the sound of vibration in the air layer is changed into resonance due to friction caused by vibration. The disadvantage is that it can cause another noise.

Therefore, in recent years, it has been developed that the sound insulation and sound absorption for noise reduction by overlapping the materials capable of cushioning and sound absorption, but due to the high characteristics of the material, practical use is impossible due to the economical efficiency, and all of these are impossible to insulate. Therefore, there is a disadvantage that a separate insulation means is required.

Therefore, in order to solve this problem, the present invention foams particles having a plurality of pores with excellent thermal insulation performance at high magnification to maximize the size of the cell (maximum porosity), and then, After passing through the membrane forming the cell in an expanded state, it is destroyed, matured, sucked into the inhaler, and injected into the molding machine through a valve, and then formed by molding the particles having the cell by swelling and being fused together by steam. As the vibration sound transmitted from flows between the destroyed membranes of the cell, the vibration sound is absorbed. In addition, this distortion is possible to compress more, thereby increasing the sound absorption rate, as well as to increase the strength and density, as well as excellent sound insulation and sound absorption performance.

In addition, by forming a bone that is indented to a certain depth on one side of the plate-shaped styropol to be formed so as to form a vent by such a bone as the vibration noise is moved along the passage to remove the vibration noise, and also These valleys are divided into a top plate and a bottom plate to each other to correspond to each other to form a single ventilation path connected to the sound absorption as well as sound insulation and heat insulation.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First of all, Styropol in the present invention is a petrochemical product, which is called EPS (Expandable Poly-Styrene Foamable Polystyrene) resin.

First, Styropol obtains PS through polymerization reaction of SM (Styrene-Monomer) decomposed in naphtha of petrochemical, and is injected into the granular state through various processes such as blowing agent (pentane gas, etc.) which is capable of foaming. It becomes Beed-Resin, and it is processed by making it expand in the molding machine by the constant pressure by steam heat (forming temperature = 108 ℃ ~ 116 ℃) by sorting it by size after first primary photoblocking.

Thus, styropol is easily foamed (expanded) by pentane gas when steam heat is applied, and when foaming, pentane gas is blown away, and these particles are adhered to each other by the steam heat, so that one block is blocked. It is molded into).

Therefore, generally used sheet material such as styropol is produced by cutting the block to a certain thickness with a hot wire, and those having a certain shape is foamed directly by using steam heat in a separate molding machine, various shapes according to the shape of the molding machine It is processed into

In addition, when the individual particles such as styropol are viewed under a microscope, a plurality of fine cells such as a honeycomb structure are formed by the membrane inside the particles, and the inside of the particles is expanded while being formed by steam heat. The surface and the membranes constituting the cell are permeated, and as the heat of vapor is permeated, it expands and carries gas.

By aging for a certain time in the molded state as described above, the vapor lamp will have a cell that is sealed while being blown away with the gas lamp and thus will have a significant restoring force after aging after foaming.

Therefore, the present invention is intended to prevent resonance caused by the cells in which vibration noise is sealed by destroying the films of the sealed cells.

To this end, in the present invention, the foaming ratio is firstly expanded to 50 times to 110 times at high magnification, and presses the particles 200 while passing through the pressurizing rollers 30 which are rotated while being in close contact with each other. The space 101 is formed by destroying the films 101 constituting the (100).

At this time, the means for pressurization is to facilitate the pressurization by the friction using the elastic roller, and any one of the pressure rollers to be rotated to be engaged must be composed of the elastic roller.

However, such a pressurization is possible even if the pressure roller 30 is not necessarily engaged with each other.

When pressurized in this way, the restoring force is about 20% to 30% of the restoring force immediately. If the restoring force is too small, the film 101 constituting the cell 100 is destroyed so that the cell 100 is blocked. As the space 102 of the blown film 101 is blocked, vibration sound cannot be moved, so that a sound absorbing effect may be lost.

Then, when the particle 200 pressurized by the inhaler 40 is sucked in a restored state to some extent and is injected into the molding machine 60 through the valve 50 or the like, the steam 200 is still injected by the molding machine 60. Complete foaming is performed by the remaining gas and the like, and the molding is completed while being fused to each other.

At this time, the temperature of the steam heat used is also in the range of about 110 ℃ ± 6 ℃, the pressure is to be a high pressure steam pressure of about 3kg / cm ₂ , under such conditions, the steam is injected into the molding machine (6) and foaming is made You will get the shape you want as you build.

As such, the mold formed in the molding machine 60 undergoes a aging process and is completed.

Therefore, in the molded state, the films 101 of the cell 100 are destroyed, and the destruction of these films 101 causes the vibration sound to move along the space 102 of the cell 100 when the vibration sound is transmitted to the upper surface. The vibration sound is gone.

That is, the vibration sound is dissipated as the vibration sound moves in the destroyed space 102 as the connection between the film 101 constituting the cell 100 and the film 101a is broken.

In addition, after the primary foaming of the particles 200 by steam heat and aged for a certain period of time after passing through the pressure roller 30 in the hopper 20 by pressing the particles 200, the cell 100 is expanded to the maximum crusher The membranes 101 and 101a constituting the cell 100 are formed to burst, and then are aged again in a aging cycle for a second period of time, so that the burst is maintained at a certain interval, and then the inhaler 40 is removed. Into the molding machine 60 through the valve 50 can be molded to the desired product by steam heat.

This approach has the advantage of gaining completeness of machining.

In other words, when roughly aged in the first foamed state by steam heat, the membranes 101 and 101a have a certain strength in the expanded state, so that the membranes 101 and 101a are easily destroyed when pressurized. In this state, since not all of the film is destroyed, gas or the like still remains.

Therefore, when molding with steam heat in the molding machine 60 is to be molded again while the particles are fused by the expansion of the particles 200 are molded.

In addition, when pressurized by passing through the pressure roller 30, the particles are completely flattened, but as soon as 20-30% is restored while passing through the pressure roller 30, in the process of secondary aging 50 Restoration of -60% is achieved, and when it is put into the molding machine and heated by steam heat in that state, it is formed while expanding by 80-90%.

Therefore, even in a foamed state at a high magnification, the density can be greatly formed, so that sound insulation as well as sound absorption are possible.

Therefore, the sound absorption rate is increased, as well as the tissues of the cells being destroyed can be closely adhered to, thereby increasing the density, and the sound insulation is also excellent.

Normally, the surface of the particles is formed of substantially fine holes, which allows free entry of steam. The surface of these particles is substantially indestructible, and the membranes of the cells formed inside the particles are destroyed.

In this case, when the compressed plate member 10 formed in the state in which the membranes of the cell are compressed and destroyed is used as a single plate, the vibration sound is transmitted to the bone 11 by forming a valley 11 having a predetermined depth on the bottom surface. As it is moved by and disappeared, and the bone 11 is formed to cross each other or communicate in a radial form by vibrating sound flows along this connected bone 11 to be extinguished.

In addition, when overlapping the single plate formed with the valleys 11 in a plurality of layers, the valleys 11 correspond to each other to form a single passage 12 so that the movement of noise with respect to the vibration sound is free.

In addition, the bone 11 or the air passage 12 is the compressed plate member 10 again in the state in which the vibration sound is first removed in a state where the membranes 101 and 101a of the cell 100 of the compressed plate member 10 itself are destroyed. It is possible to remove the vibration sound from the outside, so that the complete vibration sound can be removed, and the density of the foam can be formed largely even in the foamed state at high magnification due to the destruction of the film constituting such cells. By doing so, the workability is also easy.

In addition, when the compression plate material is used in overlap, the degree of breakage of the cell is changed according to the degree of compression, so that different compression plate materials having various compression characteristics are superimposed so that sound insulation as well as sound absorption are excellent.

At this time, by overlapping the compression plate member to form a coupling protrusion and a coupling recess, respectively, it is possible to simply overlap by engagement.

That is, for this configuration, as shown in Figs. 7 to 9, the compression plate member 10 is embodied as the upper plate 10a and the lower plate 10b, and then each of the upper and lower plates is recessed at a predetermined depth. The bone 11 is formed and the bone 11 is in communication with each other to induce extinction by the natural flow of the noise of vibration and by overlapping these bones to create a single aeration passage 12 By forming it, the vibration sound can be easily removed.

At this time, the shape of the concave bone 11 can be implemented in various forms and can be changed in the range that can be molded into a mold by steam heat using styropol and the like.

In addition, the bone 11 is to be formed in a zigzag or be zigzag bent or angular form, such that the bone 11 can be to cross each other.

The bone 11 formed as described above is formed so that one air passage 12 to be sealed is connected by overlapping the compression plate 10 corresponding to each other.

At this time, to form a checkerboard irregularities 13 to increase the binding force of the lightweight foam concrete on the upper surface (10a) of the upper plate (10a) of the compressed plate material 10, that is to cover the uneven portion ( 13) is not limited to the shape of the checkerboard can be in the form of a variety of patterns and to be implemented in various forms in the form of recesses and protrusions to strengthen the binding strength of lightweight foam concrete.

In this case, an adhesive or a separate auxiliary means may be used for binding the overlapping compression plate member 10. However, in the present invention, the upper plate 10a may correspond to portions of the compression plate member 10 that are in close contact with each other. By forming the coupling protrusions 14 and the lower plate 10b corresponding thereto, the coupling recesses 15 may be formed so that the coupling protrusions 14 and the coupling protrusions 15 may be easily engaged by engaging the coupling protrusions 14 and the coupling recesses 15.

The coupling protrusion 14 and the coupling recess 15 may be used in a variety of means so that the coupling does not occur easily after coupling.

In addition, the upper plate 10a and the lower plate 10b of the compression plate member 10 is formed by different foaming magnification of the upper plate 10a and the lower plate 10b, the degree of destruction of the film forming each cell 100 By making the different from each other it is possible to excellent the effect of sound insulation or sound absorption.

In addition, when the coupling protrusion 14 and the coupling recess 15 are engaged with each other, the sound insulation sheet 16 having a high density of materials may be formed in a middle layer between the coupling protrusions 14 and the coupling recesses 15, thereby improving the effect of sound insulation.

When the structural agent is constructed, it is usually installed on the upper side of the concrete sleeve in the same way as the floor construction, and since the lightweight foamed concrete is constructed on the upper side of the structural agent, the joint part of the compressed sheet material is poured when the lightweight foamed concrete is poured. As shown in FIG. 11, an outward jaw 17 is formed on one side of the upper plate of the compressed plate material and an inward jaw 18 is formed on the other side corresponding thereto, as shown in FIG. By overlapping with each other, when the lightweight foam concrete is poured, it prevents permeation and at the same time prevents the escape of the impact sound caused by the gap of the joint.

At this time, the outwardly facing and the inwardly facing jaw (19, 19a) is formed to prevent the left and right from being separated from the left and right coupled state by engaging with each other.

In order to prevent the escape of the impact sound can be superimposed in a variety of forms.

Therefore, the compressed plate should be directed downward to the top of the bottom layer where the concrete slab is formed over 180 mm, or if the upper and lower plates are bound together by the coupling protrusion and the recess to correspond to each other, then the upper side of the compressed slab Light-weight foam concrete, which is poured about 40 mm above the uneven part of the upper plate exposed, can be directly poured by the inward jaw 18 and the outward jaw 17 without any additional process. After the heating or cold and hot water coil pipe is formed, it is processed by finishing mortar and the construction is completed by the floor finishing material, and the construction is completed to meet the construction standards by the building method.

When the impact occurs on the bottom surface of the upper layer in the completed construction state as described above, the impact is transmitted to the lower layer while being transmitted to the lower layer with a vibration sound, the film constituting the cell of the structural agent is destroyed because it is destroyed while passing through the destroyed film Vibration noises passing through the rescue structure are dissipated as they are moved by or overlapped by the structure's overlapping vents.

In other words, it is first dissipated as it is moved to the space by the destroyed tissue of the membrane constituting the cell of the structural agent, and then moved along the aeration or valley of the compressed plate, and is moved to the air layer of the aeration or valley, and is consumed as heat energy by friction. Complete sound absorption is achieved, and in particular, the vibration sound is blocked by the elastic force of the cell of the structural agent, so that the noise between the layers is not transmitted while being transferred by the membrane, the bone or the vent of the destroyed cell, and the noise is removed. To lose.

In addition, the styropol is excellent in thermal insulation performance due to its own cell structure, which satisfies thermal insulation at the same time, so that sound insulation and sound absorption can be used at the same time, thereby enabling construction at a low price.

Although the present invention has been described as a raw material for EPS as a raw material of the structuring agent, the same effect occurs even when using EPP or fried foamed resin.

Therefore, the vibrational sound is firstly removed while the membrane constituting the cell of the structural agent is destroyed by passing through the destroyed membrane and then secondarily removed by bone or aeration, so that sound absorption is possible and the sound insulation is possible by elastic force. Vibration generated by aeration or bone is eliminated from the aeration and bone to eliminate the complete noise.Insulation performance of the styropol can be formed with high density even when foamed at high magnification by breaking by compression. Since it is possible to maintain excellently, it is possible to make the most economical and constructability excellent in the floor impact sound standard set value and insulation standard value of MDU.
