Description

Separable Low Noise Form

The present invention relates to a separate low noise die.

The formwork is a frame for maintaining the shape of the concrete in the building. The formwork must have rigidity to withstand the loads and pressures generated when the concrete is poured, and must have stable stability even after the concrete is laid. In addition, when the concrete is demineralized after curing for a certain period of time, the surface of the concrete must have a predetermined strength or more so that it is a suitable formwork. The construction related to this form is so large that it occupies about 10% ~ 15% of total construction cost and about 30% ~ 40% of frame construction cost. Also, as the buildings gradually become larger and larger, the work related to the formwork is an important process that determines the quality of the structure construction.

On the other hand, the form can be used as a plywood form, a Euro form, an aluminum form, a slip form, a gang form, a flying form, or a climbing form There are various kinds. Among them, the plywood formwork is the oldest formwork, and it has been used conveniently because it can be manufactured and installed according to the conditions of the site. However, there are disadvantages that many problems occur when the concrete is cast. In order to overcome the disadvantages of this plywood form, Euroform was developed in Europe. Eurofoam is made of plywood and steel frame and can be used repeatedly. It can be used on slab, beam, outer wall, etc.

However, as disclosed in the patent documents of the following prior art documents, the mold according to the prior art is not replaceable since the plywood is completely fixed to the frame completely. Specifically, the plywood has a rough surface due to the use of the plywood, which adversely affects the concrete surface. In this case, the plywood according to the related art has a problem that the plywood is fixed to the frame. In addition, the mold according to the prior art has no means for preventing noise, and there is also a problem that a large noise is generated during operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

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

FIG. 1 is a perspective view of a separate type low-noise form according to a first embodiment of the present invention, FIG. 2 is a perspective view showing a state before the panel is coupled to the separate low-noise form shown in FIG. 1, And FIG. 7 is a perspective view showing a state after the panel is coupled to the separate low-noise die.

1 to 3, the separate type low-noise dies 100 according to the present embodiment includes a first frame 113 formed in a planar polygonal shape and a second frame 113 provided inside the first frame 113 And is fixed to the inner side of the first frame 113 or between the first frame 113 and the second frame 115 and is formed of a resilient material and is fixed to the frame 110 And a coupling portion 120 on which the panel 140 can be detachably coupled to the fastening means 130.

The frame 110 serves to support the panel 140 and the coupling part 120 and includes a first frame 113 and a second frame 115 basically. Here, the first frame 113 is formed in a polygonal shape (normal rectangular shape) with respect to a plane, supports the rim of the panel 140, and the second frame 115 is provided inside the first frame 113 And crosses the first frame 113. A third frame 117 connected to the first frame 113 and the second frame 115 so that a first accommodation space 117a is formed between the first frame 113 and the second frame 115, . A fourth frame 119 connected to the inside of the edge of the first frame 113 may be provided so that the second accommodating space 119a is formed inside the edge of the first frame 113. The coupling portion 120 is received and fixed in the second accommodation space 119a formed by the first housing space 117a and the fourth frame 119 formed by the third frame 117. [

More specifically, the third frame 117 may be formed into a semicircular shape when viewed from the plane. The curved surface of the third frame 117 protruded inward from the first frame 113 is connected to the inner surface of the second frame 115, Lt; / RTI > At this time, the second frame 115 may extend in parallel from the curved surface of the third frame 117.

In addition, the fourth frame 119 may be formed in a fan shape when viewed from the plane. Generally, since the first frame 113 is vertically bent, the fourth frame 119 may be a sector having a central angle of 90 degrees with respect to a plane. Here, both ends of the fourth frame 119 may be connected to the inner surface of the first frame 113 located on both sides of the bent edge of the first frame 113, respectively.

On the other hand, although the material of the frame 110 is not particularly limited, it can be formed of metal, and it is made of aluminum which is relatively light in weight among the metals, so that the efficiency of work can be improved.

The coupling part 120 serves to detachably connect the panel 140 to the frame 110. The coupling part 120 may be disposed inside the corner of the first frame 113 or between the first frame 113 and the second frame 115 . The engaging portion 120 may be fixed to the second accommodating space 119a formed by the first housing space 117a formed by the third frame 117 or the fourth frame 119. [ When the third frame 117 is formed in a semicircular shape with reference to the plane, the engaging portion 120 fixed to the first accommodating space 117a defined by the third frame 117 is also engaged with the third frame 117 And may be formed in a semicircular shape when viewed from the plane. When the fourth frame 119 is formed in a fan shape as viewed from the plane, the engaging portion 120 fixed to the second accommodating space 119a defined by the fourth frame 119 is also engaged with the fourth frame 119 ), As viewed from the plane.

As described above, since the engaging portion 120 is fixed to the first accommodating space 117a or the second accommodating space 119a, the side surface of the engaging portion 120 is fixed to the frame 110 (the first frame 113, The third frame 117 or the fourth frame 119), and the upper and lower surfaces of the engaging portion 120 are exposed from the frame 110. As described above, the panel 140 can be detachably coupled to the exposed both surfaces (upper and lower surfaces) of the coupling part 120 using the fastening means 130. For example, the fastening means 130 may be non-fastened. In this case, the panel 140 may be disposed to correspond to the frame 110, and then the nails may be inserted into the panel 140 and the fastening portion 120 140 may be fixed to the engaging portion 120. Further, since the engaging portion 120 is formed of a material having elasticity, the nail can be easily removed. Accordingly, if the surface of the panel 140 is rough and adversely affects the concrete surface, the panel 140 can be easily replaced by detaching the nail from the engaging portion 120. In this manner, since the panel 140 can be used while being continuously replaced as needed, the use period of the form can be increased (see Figs. 2 to 3). In addition, prior to joining the panel 140, pre-work can be performed with only the frame 110, so the overall form weight is considerably lighter and the work speed can be increased.

4A through FIG. 4C, both sides (upper and lower surfaces) of the coupling part 120 are exposed from the frame 110, so that the panel 140 is fixed to one surface (upper surface, see FIG. 4A) (See Fig. 4B), or on both sides (upper and lower surfaces, see Fig. 4C). That is, the panel 140 can be fixed using both sides of the coupling portion 120. [ As described above, since the panel 140 can be fixed to both sides of the joint portion 120, the exclusive rate of the die can be increased.

Although the material of the coupling part 120 is not particularly limited, the coupling part 120 may be formed of soft PVC so that the fastening means 130 such as a nail can be easily inserted or removed. In addition, the panel 140 may be formed of a flat plate so as to support the concrete, but it is possible to improve the quality of the concrete installation surface by using, for example, a coated plywood have. In addition, the panel 140 may be aluminum, a hard fiberboard, a composite site, a steel plate, or the like.

5, the concave and convex portions 127 may be formed on both surfaces (upper and lower surfaces) of the joint portion 120 exposed from the frame 110. [ Here, concave and convex portions 127 and convex portions 125 protruding from concave and convex portions 127 are continuously repeated. As described above, by providing the concave-convex portion 127 on both surfaces (upper and lower surfaces) of the coupling portion 120, the contact force with the panel 140 can be enhanced.

A depressed groove 129 may be formed on one side (side surface) of the engaging portion 120 facing the frame 110. Here, the grooves 129 may be formed to be recessed at a certain depth from one surface of the coupling part 120, and may be formed by patterning a plurality of grooves 129 at regular intervals along one surface of the coupling part 120. By forming the groove 129 in the engaging portion 120, the weight of the engaging portion 120 itself can be reduced.

1, the engaging portion 120 is disposed in the first accommodation space 117a or the second accommodation space 119a, and then the frame 110 (the first frame 113, the third frame 113, A screw 155 may be inserted into the frame 110 through a fastening hole 150 penetrating the frame 117 or the fourth frame 119 in the thickness direction. Therefore, the coupling portion 120 can be used while being replaced as needed. Basically, since the engaging portion 120 is formed of flexible PVC or the like having elasticity, the fastening means 130 such as a nail can be repeatedly inserted or removed to replace the panel 140 several times. However, even if the engaging portion 120 is completely damaged by the fastening means 130 such as a nail, the screw 155 inserted through the fastening hole 150 is removed and the new engaging portion 120 is screwed again , The engaging portion 120 can be replaced.

Meanwhile, since the coupling portion 120 is formed of a material having elasticity as described above, the vibration of the frame 110 and the panel 140 can be absorbed and noise can be reduced. Specifically, since noise is a type of sound, human can feel it by stimulating the eardrum through the vibration of the air. At this time, the intensity of the noise is determined according to the amplitude. That is, when the amplitude increases, the noise increases, while when the amplitude decreases, the noise decreases. Therefore, when the coupling part 120 is fixed to the frame 110, the coupling part 120 absorbs the amplitude of the frame 110 and the panel 140, and the amplitude of the frame 110 and the panel 140 is small The noise can be reduced. Particularly, when the frame 110 is made of aluminum, a unique high-pitched sound is generated. However, due to the joint portion 120 formed of a material having elasticity, noise can be reduced.

FIG. 6 is a perspective view of a separate low-noise form according to a second embodiment of the present invention, and FIG. 7 is a cross-sectional view of the frame and the noise preventing member shown in FIG.

As shown in FIGS. 6 to 7, the separable low-noise form 200 according to the present embodiment has a noise-preventing member 160 in addition to the separate low-noise form 100 according to the first embodiment. Therefore, the separate type low-noise dies 200 according to the present embodiment will be described with reference to the noise preventing members 160, omitting duplicate contents of the separate low-noise dies 100 according to the first embodiment.

In the separate type low-noise dies 200 according to the present embodiment, holes 170 penetrating through the frame 110 in the thickness direction may be formed, and the noise preventing member 160 may be inserted into the holes 170. Here, the noise preventing member 160 absorbs the vibrations of the frame 110 and the panel 140 similar to the coupling unit 120, thereby reducing noise. That is, when the noise preventing member 160 is inserted into the hole 170 of the frame 110, the amplitude is reduced, and noise can be reduced. More specifically, when the vibration of the frame 110 and the panel 140 is transmitted to the noise preventing member 160, the vibration of the panel 140 and the frame 110 is absorbed by the noise preventing member 160, Can be reduced.

 At this time, the noise preventing member 160 is not limited as long as it is a material having elasticity so as to absorb vibration, but it may be formed of a silicone rubber. These silicone rubbers are not only elastic and soft but also excellent in heat resistance, cold resistance, oil resistance, and chemical resistance, and are suitable for use in a construction site.

The noise preventing member 160 may be composed of the fixing portion 161, the connecting portion 163, and the vibrating portion 165. Here, the fixing portion 161 is inserted and fixed in the hole 170 formed in the frame 110. Therefore, the fixing portion 161 is formed in a shape corresponding to the hole 170. [ The connecting portion 163 connects the fixed portion 161 and the vibrating portion 165 and extends from the fixed portion 161 and has a smaller sectional area than the fixed portion 161. [ The vibrating portion 165 is substantially oscillating and extends from the connecting portion 163, but has a larger cross-sectional area than the connecting portion 163. When the vibration of the frame 110 and the panel 140 is transmitted to the noise preventing member 160 in a state where the fixing portion 161 is fixed to the hole 170 of the frame 110, And the vibration unit 165 vibrates based on the connection unit 163. [ As a result, there is an effect that noise can be reduced by absorbing vibration of the frame 110 and the panel 140 while the vibration unit 165 vibrates. Here, the vibration unit 165 is not particularly limited, but may be formed into a columnar shape whose ends are rounded.

The first protrusion 167 and the second protrusion 169 may be formed on the noise preventing member 160 in order to fix the noise preventing member 160 to the hole 170 of the frame 110. Here, the first protrusion 167 may protrude vertically from the noise preventing member 160 to contact one surface of the frame 110, and the second protrusion 169 may protrude from the other surface of the frame 110, And may protrude vertically from the member 160. The first protrusions 167 and the second protrusions 169 are caught by one surface of the frame 110 and the other surface of the frame 110 so that the noise preventing member 160 is inserted into the hole 170 of the frame 110 Can be completely fixed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
