Description

One-body form constructing a form

The present invention relates to a unitary formwork, and more particularly, to a unitary formwork forming an integral structure with the concrete to be cast using an air panel to be soundproofed and insulated through a space filled with air.

As a building panel used for sound insulation and heat insulation in the conventional building field, a product using styrofoam, glass sole, urethane, and the like are still widely used.

By the way, chemicals such as styrofoam are easy to burn, there is a problem that not only is a large amount of waste induced, but also difficult to process the generated waste.

Of course, there were products using flame retardant materials, but these products were very expensive, causing problems of large increase in construction cost.

In addition, since the product using the air tube is in the form of a single air bag is limited to drilling or cutting, there was a considerable difficulty in the installation work.

In order to solve this problem, a plurality of air bags isolated by the inventor of the present application, such as Korean Patent Application No. 10-2001-0001069 (Publication No. 2002-0059910) can be generated to obtain insulation and sound insulation effects. Architectural air panels were created.

On the other hand, not only the conventional styrofoam construction panel or air tube construction panel but also the building air panel was to be installed on the concrete wall or pillar of the hardened building.

In other words, after the concrete was cast and hardened to form the walls or pillars of the building, the installation or fixing of the building air panels on the walls or pillars required a separate installation process.

For this reason, a lot of manpower and time are required for the installation of construction air panels, which causes a problem of rising construction costs.

In addition, there has been a problem that deformation does not occur while maintaining a solid installation state such as a gap is generated between the wall and the pillar over time after installation.

The present invention is to solve the above problems, more specifically, the installation is not only simple, but also maintain a solid installation state, excellent insulation effect, as well as thin and excellent sound insulation effect, integral with the concrete to be poured The purpose is to provide a unitary formwork that takes place.

In the integrated form of the present invention, a plurality of columnar protrusions are formed toward the upper side, and a blocking wall is provided between the columnar protrusions and the protrusions so that a space is formed between the protrusions and the protrusions, and formed in the space forming body. It consists of a flexible sheet of synthetic resin that is bonded to the upper end of the projection to block the space between the projection and the body and integrated with the space-forming body, and a soundproof sheet that is adhered to the blocking sheet to absorb sound waves from the air. An air panel; It consists of a fixing means for connecting and fixing a pair of air panels installed to be spaced apart by a predetermined interval so that the concrete is poured inside, characterized in that to form a structure integrally with the concrete poured and filled inside.

In addition, the air panel is characterized in that the fixing force reinforcing means is further formed so that the bonding force with the concrete to be poured is firm.

Here, the fixing force reinforcing means is characterized in that it consists of a plurality of concrete inlet grooves formed in the air panel so that a portion of the concrete to be poured is hardened.

In addition, the fixing force reinforcing means is characterized in that the irregularities formed on the surface of the air panel.

In addition, the fixing force reinforcing means is characterized in that the hair is formed, or made of a fabric with a fine groove is formed on the surface of the air panel.

In addition, the projection of the space-forming body is a columnar shape of the hollow inside, characterized in that the lower portion of the space-forming body is attached to the soundproof sheet to increase the sound insulation effect by absorbing air propagation sound.

In addition, a synthetic resin panel is attached to the lower portion of the soundproof sheet attached to the lower portion of the space-forming body.

In addition, the height d2 of the blocking wall may be smaller than or equal to the height d1 of the protrusion.

In addition, the air panel has a structure in which the space forming body and the blocking sheet form one cell and a plurality of cells are stacked.

In addition, the barrier wall of the space-forming body is formed to be thin so as to have excellent absorption efficiency of the vibration due to the air propagation sound impingement, but has a "T" -shaped cross section so that the upper end portion has a large area to facilitate adhesion with the barrier sheet. It features.

In addition, the blocking wall of the space-forming body is formed mostly thin so as to have excellent absorption efficiency of vibration caused by the air propagation sound impingement, but has a thin blocking wall with a wide blocking wall having a wide upper end to be firmly adhered to the blocking sheet. Positioned while forming the zone is characterized in that the vibration absorption efficiency of the thin barrier wall is excellent and the transmission of the vibration to the side by the barrier wall is wide at the top end.

Integral formwork of the present invention is provided with a fixing force reinforcing means that can be firmly integrated with the hardened concrete as the pour concrete is hardened, and harden by pouring concrete to the form in the state using the air panel during construction of the formwork Concrete and air panels are firmly integrated.

This is because the blocking sheet of the flexible synthetic resin material is bonded to the upper end of the space forming body in which a plurality of columnar protrusions protrude, and the space between the protrusions and the protrusions is blocked, so that an insulation effect can be obtained, and the blocking sheet is flexible to absorb primary The remaining air propagation sound is absorbed, and the sound-absorbing sheet absorbing air propagation sound is adhered to the blocking sheet, so that the air absorption sound is first absorbed to obtain a thin and excellent sound insulation effect. It can maximize the effect of insulation and sound insulation by triple.

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

However, the accompanying drawings are only examples to illustrate the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

The present invention relates to a formwork using an air panel having an insulation and sound insulation effect.

Therefore, in the present invention, the heat insulation effect and the sound insulation effect are obtained through a plurality of spaces filled and isolated as in the prior art.

By the way, the air panel constituting the present invention is thinner than the conventional, has the purpose of making the sound insulation effect is excellent as well as double, triple as well as excellent thermal insulation effect.

The inventor of the present application devised a structure as shown in FIG. 1 after a long research and effort.

In the air panel of FIG. 1, a plurality of columnar protrusions 11 are formed upward, and a blocking wall 12 is provided between the columnar protrusions 11 and the protrusions 11 so that the protrusions 11 are formed. And a space forming body 10 having a space formed between the protrusions 11.

In addition, the sheet is bonded to the upper end of the projection 11 formed in the space forming body 10 to block the space between the projection 11 and the projection 11 and the blocking sheet of flexible synthetic resin material which is integrated with the space forming body 10 ( 20) is provided.

Moreover, the soundproof sheet 30 which improves a sound insulation effect by absorbing the air propagation sound adhering on the blocking sheet 20 and hits is provided.

In FIG. 1, the blocking wall 12 formed in the space forming body 10 connects the protrusions 11 and the protrusions 11 to prevent deformation of the space forming body 10, and thus firmness of the space forming body 10. It acts to secure the ship.

In addition, the barrier wall 12 is of a wall type to isolate the space between the protrusion 11 and the protrusion 11 so that when a breakage occurs, heat is transferred, or an air field is transferred to a specific part of the space, Prevents affecting space.

The height d2 of the blocking wall 12 is preferably formed to be equal to or smaller than the height d1 of the protrusion 11.

Since the projection 11 of the space-forming body 10 has a columnar shape, it is easy to block the space located between the projection 11 and the projection 11 with a sheet.

That is, the blocking sheet 20 is bonded to the upper end surface of the protrusion 11 using an adhesive or the like to block the space between the protrusion 11 and the protrusion 11 while being integrated with the space forming body 10.

In the present invention, in the manufacture of the structure using the concrete, as shown in Figure 3, because it is placed in the use of the formwork (1) is in contact with the concrete of the state before hardening, the blocking sheet 20 and the space-forming body 10 is firm It is particularly important that concrete is prevented from flowing into the space between the protrusions 11 and the protrusions 11. The protrusions 11 have a columnar shape to provide a wide contact surface, thereby obtaining a firm adhesive state.

The space-forming body 10 as described above may be made of elastic (non-osmotic) polyethylene (polyethylene), polypropylene (polypropylene), fluorine plastic (fluor plastic), and the like, inorganic flame retardant material, glass flame retardant material, mineral flame retardant material , Metal flame retardant, carbonized flame retardant and organic flame retardant are preferably used.

The reason why the barrier sheet 20 is implemented as a flexible synthetic resin material is to absorb the airborne sound remaining after the soundproof sheet 30 adhered to the barrier sheet 20 is primarily absorbed.

That is, when the residual air propagation sound is transmitted to the blocking sheet 20, the blocking sheet 20 is flexibly moved to absorb the remaining air propagation sound again.

As the material of the barrier sheet 20, polyethylene, polypropylene, fluoroplastic, or the like is suitable.

In the case where the blocking sheet 20 and the space forming body 10 are bonded to each other, the spaces formed between the protrusions 11 and the protrusions 11 of the space forming body 10 are completely closed. It may be.

To this end, the top surface of the blocking wall 12 should be wide and flat so that the blocking sheet 20 can be firmly adhered to both the top walls of the respective blocking walls 12 and the projections 11.

As described above, if each space is implemented in a completely closed form, even if concrete is introduced between the blocking sheet 20 and the space forming body 10 at a specific point, the concrete is prevented from spreading to neighboring points. can do.

However, it is never easy to secure such a structure, and this leads to an increase in manufacturing cost due to the need for high precision.

Therefore, at least one of the bonding portions of the blocking sheet 20 and the space forming body 10 is bonded to the edge of the space forming body so that there is no gap, so that the poured concrete is located inside the edge of the space forming body 10. Preventing the inflow into the space between the projections and the projections, the adhesion of the blocking wall 12 and the blocking sheet 20 located inside the edge can be made without a great problem even if not completely made.

In Figure 1, the thickness of the barrier wall located at the edge of the space-forming body 10 is so thick that the barrier sheet can be firmly bonded.

When all of the blocking walls 12 and the blocking sheet 20 are completely bonded and integrated, the soundproofing effect is lowered because it impedes the absorption of the remaining sound waves.

Therefore, the bonding portion positioned at the edge of the bonding portion of the blocking sheet 20 and the space-forming body 10 is completely bonded so that there is no gap, and the blocking sheet 20 and the space-forming body 10 inside thereof are not bonded. It is desirable to have nothing present.

The soundproof sheet 30 of FIG. 1 is located in a position where air propagation sound is first contacted with the air panel 100 so that most air propagation sound that is hit is absorbed.

The soundproof sheet 30 may use a variety of materials already known.

In a specific example, a nonwoven fabric, a plastic film, or the like can be used.

In bonding the soundproof sheet 30 to the blocking sheet 20, it is most preferable to adhere the adhesive sheet through an adhesive or the like, but may also be bonded in a velcro manner.

Meanwhile, the present invention arranges the pair of air panels 100 to face each other as shown in FIG. 3 and connects the pair of air panels 100 through the fixing means 2 to produce the formwork 1. When the concrete is poured into the formwork 1, the hardened concrete and the air panel 100 are integrated to obtain a solid installation state.

For this reason, the air panel 100 of the present invention is provided with a fixing force reinforcing means.

That is, a fixing force reinforcing means is formed in the air panel 100 so that the hardened concrete and the air panel 100 can be firmly integrated.

Such fixing means can be implemented in various forms.

Specifically, the fixing force reinforcing means may be a fabric attached to the lower portion of the air panel 100 and the hair is formed.

That is, the concrete and the air panel 100 to be hardened due to the wool formed on the fabric is to be tightly integrated.

As another form, it may be a fabric attached to the lower portion of the air panel 100 and formed with fine grooves.

In other words, the concrete is introduced into the fine groove present in the fabric to harden to obtain a solid integration.

In addition, the fixing force reinforcing means may be implemented in a form having a plurality of concrete inlet groove 41 formed in the air panel 100 so that a portion of the concrete to be poured is inserted and cured.

4 is smaller than the concrete filling space 42 so that concrete can be introduced into the concrete filling space 42 formed in the projection of the space forming body 10 constituting the air panel 100 and the concrete filling space 42. It shows a structure having a concrete inlet groove 41 formed.

Concrete inlet groove 41 as described above may be formed by the blocking plate 20 and the space forming body 10 as shown in FIG.

In addition, the fixing force reinforcing means may be implemented in the form of irregularities formed on the lower portion of the air panel 100.

The protrusion 11 of the space-forming body 10, which is a component of the present invention, is embodied in a columnar shape with an empty inside as shown in FIG. 1, and the sound-absorbing effect is absorbed by absorbing air propagation sound in the lower portion of the space-forming body 10. The height is preferably bonded to the soundproof sheet (50).

According to such a structure, the effect which the residual air propagation sound which passed the blocking sheet 20 is absorbed also by a process can be expected.

Of course, as the thickness of the projection 11 is thinner, the absorption effect of air propagation sound is increased, but the rigidity of the building air panel is relatively lowered.

Therefore, it is desirable to determine the thickness of the projection considering two things.

If the soundproof sheet 50 is not firm in the above structure, as shown in FIG. 5, a hard synthetic resin panel 60 is adhered to the lower portion of the soundproof sheet 50 to prevent concrete from flowing into the empty space of the protrusion 11. It is preferable.

In the present invention, when the blocking wall 12 of the space-forming body 10 is implemented to absorb vibrations by air propagation sound can increase the sound insulation effect.

However, when the blocking wall 12 of the space-forming body 10 is implemented to be thin enough to absorb vibrations caused by air propagation sound, the blocking sheet 20 and the blocking wall 12 may not be smoothly bonded.

Therefore, in the implementation of the barrier wall 12, when the thinner is implemented so as to have a good absorption rate of vibration due to air propagation sound, the barrier wall 12 has a large area at the upper end as shown in FIG. It is preferable to implement in the "T" shape.

Of course, as shown in Figure 8, the blocking wall 12 of the space-forming body 10, the upper portion is formed to be mostly thin so that the absorption efficiency of vibration due to the air propagating sound hitting, but firmly bonded to the blocking sheet 20 It is also possible to implement such that the wide barrier wall 12 is positioned while forming a zone with the thin barrier wall 12 inside.

That is, the vibration absorbing efficiency is improved by the thin blocking wall 12, and the upper end portion is blocked by the vibration is not transmitted to the side by the wide blocking wall 12.

FIG. 7 shows that the blocking walls 12 are not all made of a “T” shape, but rather the “T” shape blocking walls 12 are located while forming a zone.

In implementing the air panel 100 constituting the formwork 1 of the present invention, as shown in FIG. 5, the space-forming body 10 and the blocking sheet 20 form one cell, and a plurality of cells are stacked. It can be implemented to have a structure.

Such a structure has a disadvantage in that the thickness of the building air panel 100 is increased, but the sound insulation and insulation effect can be greatly increased.

The present invention can be used for the construction for soundproofing and insulation in the construction field, such as the construction of buildings such as industrial factories, warehouses, or internal wall construction of houses.
