At this time, when dismantling the inner formwork, for example, the inner gangform also known as al-foam more noise and dust than other structures, causing a lot of problems.

In this regard, the noise and dust generated during the disassembly of the formwork may be emitted to the outside of the building through an open area formed in the building to form a balcony or window. It causes the inconvenience of living for the residents.

In order to solve this problem, recently, a method of dismantling an internal gang form, that is, an internal formwork, is applied while blocking an opening formed in a building with a separate shielding panel.

By the way, in the prior art, since the shielding panel is a simple rectangular plate type, it is not easy to install and dismantle. In particular, when the size of the opening is large, considering that the shielding panel must be manufactured, transported and installed accordingly. Therefore, there is a need for a new concept of building opening shield that is not known.

Referring to these drawings, according to the formwork structure according to the present embodiment can be easily and effectively shielding the opening (1) of the building as a simple and effective structure that occurs in the process of dismantling the form, in particular the process of dismantling the inner gangform 40 Noise and dust external emissions can be prevented, and the assembly structure facilitates on-site installation and disassembly and assembly, thus increasing workability.

The formwork structure according to the present embodiment, which can provide such an effect, may be installed, for example, as shown in FIG. 1 may refer to, for example, a high-rise building such as a building or an apartment.

The formwork structure is detachably installed in the formwork assembly 10 installed on the inside and the outside of the wall 3 and the opening part 1 formed in the building for constructing the wall 3 of the building, and the opening part 1. It may include a building opening shield 100 to block the noise and the external emission of the branch through.

The formwork assembly 10 is a means for building the walls 3 of a building. That is, the mold assembly 10 is constructed and installed to protect from external influences while preventing the leakage of water until the concrete is hardened, as well as maintaining a predetermined shape and dimensions during the curing of concrete.

The formwork assembly 10 has an outer gang form provided in the outer wall forming form 20, the outer wall frame structure 30 is provided on the outside of the outer wall forming form 20, and the outer wall forming form 20 ( 40).

The concrete 3 is formed between the outer wall forming form 20 and the inner gang form 40 to form a wall 3.

The outer wall frame structure 30 supports the formwork 20 for forming the outer wall, and is a structure for the worker's working environment, including the chief plate 35. It can be manufactured by bolting or welding steel structures.

Looking at this, the outer wall frame structure 30 is a plurality of horizontal frame 31 which is arranged to be spaced apart from each other, is arranged to cross the horizontal frame 31, spaced apart at equal intervals, the building opening shield 100 on one side And a plurality of vertical frames 32 connected thereto.

The plurality of chieftain plates 35 are provided in the space between the vertical frame 32 and the dummy frame 33. The chief plate 35 is a foothold that the operator stands on. Chieftain plate 35 may be installed in a corresponding position in a removable structure.

On the other hand, as described above, the formwork structure of Figure 1 forms the mold so that the cast concrete can maintain a predetermined shape and dimensions, it is dismantled when the concrete curing is completed. At this time, a lot of noise and dust is generated in the process of dismantling the inner gang foam 40 generates a lot of problems.

That is, noise and dust generated during dismantling of the internal gang form 40 may be emitted to the outside of the building through the opening part 1 formed in the building for the formation of a balcony or window. Causes inconvenient living for residents. Therefore, in order to solve such a problem, a new concept building opening shield 100 is applied.

1 illustrates that the building opening shield 100 is applied to only one side of the opening 1, but this is optional. That is, the building opening shield 100 may be applied to all of the openings 1 beyond those shown. Therefore, the scope of the present invention is not limited to the shape of the drawings.

The building opening shield 100 includes first and second unit casings 110 and 120 that are spaced apart and accessible in the + R direction or the ?? R direction as shown in FIGS. 2 and 3.

Since the first and second unit casings 110 and 120 may be spaced apart and approached in the + R direction or the ?? R direction, they may be commonly applied to the openings 1 having different sizes. Of course, what is necessary is just to select the shielding panel unit 130 of the size according to it. Unlike the steel structure, the shielding panel unit 130 can be manufactured in a large size, so there is no difficulty in application.

The first unit casing 110 has a loop shape in which a first pocket 111 is formed therein but one side is open.

The first unit casing 110 is coupled to one edge surface of the opening 1. To this end, the first unit casing 110 is provided with a first coupling flange 112 that forms a place to engage with one side edge surface of the opening 1. The first coupling flange 112 may be applied in plurality.

Similarly to the first unit casing 110, the second unit casing 120 also has a loop shape with one side open. That is, the second unit casing 120 has a second pocket 121 formed therein, is connected to the first unit casing 110 to form a closed loop, and is coupled to the other edge surface of the opening 1. To this end, the second unit casing 120 is provided with a second coupling flange 122 that forms a place to engage the other edge of the opening (1). The second coupling flange 122 may be applied in plurality.

As described above, the second unit casing 120 is capable of relatively approaching or spaced apart from the first unit casing 110. In other words, since the size adjustment between the first and second unit casing (110,120) is possible, it is advantageous to apply to the opening 1 having a different size in common.

A plurality of first fixing members 141 may be applied to fix the first and second unit casings 110 and 120 with the gap adjusted.

The plurality of first fixing members 141 are fastened to the through holes 113 and 123 formed at the contact portions of the first and second unit casings 110 and 120 to fix the first and second unit casings 110 and 120. .

The shielding panel unit 130 is inserted into the first and second pockets 111 and 121 of the first and second unit casings 110 and 120.

The shielding panel unit 130 shields the inner gang form 40 by shielding the opening 1 of the building in a state in which the shielding panel unit 130 is disposed in the first and second pockets 111 and 121 of the first and second unit casings 110 and 120. To prevent noise and dust from being released during disassembly.

The first and second unit casings 110 and 120 are provided with frame supports 160 to which lower ends of the vertical frames 32 are directly connected. The frame support 160 is applied to both the first and second unit casings 110 and 120. The frame support 160 is bolted or welded to the first and second unit casings 110 and 120, respectively.

The frame support 160 is provided in the first and second unit casings 110 and 120, respectively, and the lower end of the vertical frame 32 is partially inserted to serve to move the vertical frame 32 in position. That is, according to the position of the vertical frame 32 can be assembled while moving the building opening shield 100 slightly in the + P direction or ?? P direction as shown in FIG.

A plurality of second fixing members 142 are used to fix the vertical frame 32 inserted into the frame support 160. The plurality of second fixing members 142 are inserted into the through holes 161 of the frame support part 160 to be fastened to the through holes 32a of the vertical frame 32 so that the vertical frames 32 are fixed to the frame support parts 160. do.

With this configuration, when the formwork assembly 10 is constructed by constructing the wall 3 of the building as shown in FIGS. 5 and 6, the opening 1 formed in the wall 3 of the building is opened as shown in FIG. 7. The secondary shield 100 may be installed. In this case, by installing the building opening shield 100 on the vertical frame 32 which is one component of the formwork assembly 10 as described above, the installation is convenient and can be easily dismantled later.

According to this embodiment acting on the basis of the structure as described above, it is possible to easily shield the opening 1 of the building as a simple and effective structure in the process of dismantling the form, in particular in the process of dismantling the inner gangform 40 Noise and dust emitted from the outside can be prevented, and the assembly structure facilitates field installation and disassembly, thereby increasing workability.

8 is a perspective view of a shielding panel unit of a building opening shield according to a second embodiment of the present invention, and FIG. 9 is an exploded view of FIG. 8.

In the present embodiment, the shielding panel unit 230 having a structure as shown in FIGS. 8 and 9 may be applied to the opening 1 of the building. The peripheral structure for mounting the shielding panel unit 230, that is, the structures of the first and second unit casings 110 and 120 are the same as in the above-described embodiment and thus will be omitted.

The shielding panel unit 230 may include a functional shield 240 and a pair of reinforcing non-combustible outer shells 260 coupled to both surfaces of the functional shield 240.

The reinforcement nonflammable outer shell 260 reinforces the functional shielding part 240 and does not burn by being nonflammable.

The functional shield 240 is a portion disposed between the pair of reinforcing nonflammable outer shells 260 and serves as a shielding function. Of course, it provides a sound absorption and flame retardant function in addition to the shielding function.

The functional shield 240 is a corrugated core material 241 made by flame-retardant corrugated cardboard, a shielding sheet 251 disposed on one surface of the corrugated core material 241 and bonded to the corrugated core material 241, and a corrugated core material 241. It may include a sound absorbing sheet 253 disposed on the other side of the cardboard core 241 and bonded to.

The shielding sheet 251 may be applied to a urethane material to perform a shielding function. The sound absorbing sheet 253 may be applied as a sponge material to perform a sound absorbing function. At this time, since the shielding sheet 251 can be made thicker than the sound absorbing sheet 253, it can provide a reliable shielding function.

In this way, while the shielding sheet 251 and the sound absorbing sheet 253 are responsible for the individual shielding and sound-absorbing function, the central corrugated core 241 is responsible for the shielding and sound-absorbing function at the same time, in addition to the additional flame retardant function to provide. That is, since the corrugated core material 241 is made of flame-retardant corrugated cardboard, it is light in weight and provides an advantage of lowering manufacturing costs.

Explain more. In manufacturing the functional shield 240 in the present embodiment, the flame-retardant corrugated core material 241 replaces the middle portion of the shielding sheet 251 and the sound-absorbing sheet 253, thereby manufacturing the shielding panel unit 230. And balance in terms of cost, strength, weight, workability, and the like in installation. In addition, the following features can be provided.

By adhering the corrugated core material 241 on both sides of the shielding sheet 251 and the sound absorbing sheet 253, the curving progresses after the shielding sheet 251 and the sound absorbing sheet 253 are molded, and the warping phenomenon continues. The corrugated core material 241 formed in all directions is held in an attached state, and structurally sufficient strength reinforcement can be made to withstand external impacts well.

By replacing part of the shielding sheet 251 and the sound absorbing sheet 253 with the corrugated core member 241, the lower cost of the corrugated core member 241 can be further reduced in weight while lowering the manufacturing cost. It can provide a beneficial effect.

By replacing the middle portion of the shielding sheet 251 and the sound-absorbing sheet 253 with the corrugated core material 241, when the heat, vibration and noise generated from one side is transferred to the other side, the corrugated core material 241 is shielded sheet ( 251 and the sound-absorbing sheet 253 can be significantly reduced while passing through the air layer reliably formed, thereby improving heat insulation on the other side, in particular, sound insulation.

When the shielding panel unit 230 having such a structure is applied, the shielding panel unit 230 may provide a much higher shielding function than a conventional shielding panel (not shown), as well as a sound absorption function and a flame retardant and non-flammable function. There is a growing advantage.

Even if the present embodiment is applied, it is possible to easily shield the opening part 1 of the building as a simple and effective structure to prevent the external emission of dust and dust generated in the process of dismantling the form, especially in the process of dismantling the inner gangform 40. In addition, the assembling structure facilitates field installation and disassembly and assembly, thereby increasing workability.

10 is an exploded perspective view of the building opening shield according to the third embodiment of the present invention.

Referring to these drawings, the building opening shield 300 according to the present embodiment also includes first and second unit casings 310 and 320, and pockets 111 and 121 of the first and second unit casings 310 and 320. It has a structure in which the shielding panel unit 330 is inserted.

In this case, the first and second unit casings 310 and 320 are manufactured to be separated into unit casing portions 310a, 310, 320a and 320b, respectively. In this case, there is an advantage that the internal size of the first and second unit casings 310 and 320 can be easily adjusted. The fixing of the first and second unit casings 310 and 320 is a bolting structure as described above.

Luminous patterns 380 are formed in the first and second unit casings 310 and 320. The luminous pattern 380 may be a paint or a tape. When the luminous pattern 380 is applied, there is an advantage that it is easy to determine whether the building opening shield 300 is installed even in a dark night.

An observation window 331 is formed in the shielding panel unit 330. When the building opening shielding device 300 is installed, a blocked structure is formed, but the external view may be partially enabled by the observation window 331.

Even if the present embodiment is applied, it is possible to easily shield the opening part 1 of the building as a simple and effective structure to prevent the external emission of dust and dust generated in the process of dismantling the form, especially in the process of dismantling the inner gangform 40. In addition, the assembling structure facilitates field installation and disassembly and assembly, thereby increasing workability.

As described above, the present invention is not limited to the described embodiments, and various modifications and variations can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
