Description

TECHNICAL FIELD [0001] The present invention relates to a concrete panel for floor construction of a building, a method for manufacturing the same, and a floor construction structure including the same. [0002] Conventionally,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete panel for floor construction of a building, a method of manufacturing the same and a floor construction structure including the same, more specifically, The present invention relates to a concrete panel for floor construction of a building that can be firmly and simply installed on the floor of a building, a method of manufacturing the same, and a floor construction structure including the same.

In building multi-storied buildings such as multi-family houses (villas, etc.) and apartments, it is common that almost all work is done at the construction site. However, in the case of an apartment or the like, a prefabricated method using a PC method may be used.

The construction method of general multi-story building will be briefly described as follows.

First, foundation work such as earthwork and earth compaction is going on. Then, a skeletal structure of the building is formed by using a steel frame such as an H-beam and an I-beam on the ground. Specifically, a plurality of steel frame frames are installed vertically and horizontally, and then steel frame frames are welded or brazed together to form a skeleton structure of the building.

Next, bricks are installed between the vertically installed steel frame frames or the formwork is installed to connect the reinforcing bars to each other. Then, the concrete is laid and cured to construct the wall. Then, a horizontally installed steel frame is laid out with a formwork (typically 'Euroform'), a reinforcing bar is connected to the frame, and concrete is laid and cured to construct a slab. In this way, after concrete pouring and curing, after a certain period of time, if the form is dismantled, one layer is constructed. Then, by repeatedly installing the formwork, pouring concrete, and curing work several times, we construct several layers. The building thus constructed is divided into walls and slabs so as to accommodate several generations, and has a multi-layered structure, and at the same time, is divided into several living spaces in one layer.

At this time, in constructing the slab floor of the building, it is important to block noise and vibration between the floor (lower and upper floors). The shocks from the upper floors, especially the shocks caused by the severe fluctuations of the children in the apartments, cause severe damage to residents living in the lower floors. Accordingly, the installation of a shock absorber for impact absorption and a sound insulating material for exhausting noise can be said to be essential for the floor construction work of the building.

In order to prevent noise and vibration between these layers, sound insulation / cushioning materials such as rubber material and synthetic resin foam are generally installed at the bottom of the slab. For example, in Korean Patent No. 10-0166993 (Patent Document 1), a rubber material is laid on a floor base slab, and a polyethylene (PE) foamed sponge is laid thereon to form a barrier layer. Then, A method of constructing a floor structure for preventing floor impact noise by adhering a floor layer (floor material) on a sponge is proposed.

Korean Patent Laid-Open No. 10-2006-0038862 (Patent Document 2) discloses a foamable material having a foam expansion ratio of 5 to 200 times and a foam having a diameter of 10 to 3,000 탆, which can be used as an anti- A thermoplastic flame retardant foam having a cell has been proposed.

However, the floor construction according to the related art disclosed in the above Patent Documents 1 and 2 has a problem in that it can not effectively block the noise and vibration applied in the upper layer even if the sound insulation / damping material is installed. As a result, residents living in the lower floors are severely damaged by noise and vibration.

Further, as disclosed by the present inventors, Korean Patent No. 10-0757011 (Patent Document 3) and Korean Patent Registration No. 10-0954827 (Patent Document 4) disclose a floor construction structure for providing soundproofness and dustproofness through a hollow portion . However, although it has a soundproof and dustproof property by the hollow portion, it is pointed out that the installation work is somewhat complicated.

On the other hand, the floor construction structure according to the prior art is intended to purchase heating pipes in the finished mortar in heating. However, this causes a problem of a large amount of energy consumption because the thermal conductivity is low.

Korean Patent No. 10-0166993 Korean Patent Publication No. 10-2006-0038862 Korean Patent No. 10-0757011 Korean Patent No. 10-0954827

The buffer member 220 has elasticity, which is inserted into the post 210 to provide a buffering force. The buffer member 220 is not limited as long as it has elasticity. The buffer member 220 can be, for example, a coil spring (a normal spring structure), but is selected from a disc spring according to a preferred embodiment of the present invention. In the figure, a dish spring is shown as a preferred embodiment of the cushioning member (220).

The buffer member 220 is preferably formed of a dish spring in which a plurality of dish members 222 are stacked. The plate member 222 is an elastic metal member, and it may be made of a material such as carbon steel, stainless steel (SUS), aluminum alloy steel, and steel. At this time, a buffer hole 220a is formed at the center of the plate member 222, and the post 210 is inserted into the buffer hole 220a. Referring to FIG. 11, two dish members 222 are stacked in opposite directions to form one spring set, and one or more such spring sets may be stacked.

Fig. 11 illustrates a cushioning member 220 composed of three spring sets. Specifically, FIG. 11 shows a state in which six dish members 222 are used, and two dish members 222 stacked in opposite directions form one spring set. .

12 and Fig. 13 show one dish member 222. Fig. As shown in Figs. 12 and 13, the plate member 222 has a buffer hole 220a formed at the center thereof, and a plate 222a in the shape of a cap in the circumferential direction with respect to the buffer hole 220a, Is formed at a predetermined angle. Therefore, when receiving an external force such as an impact applied from the outside, the freshly shaped dish 222a spreads at a predetermined angle to buffer the external force, which also has a sense of stability. Two of these plate members 222 are stacked in a direction opposite to each other by a single spring set, and have an effective buffering force. That is, such a diaphragm spring implements a more stable buffering force than a coiled spring, which is also structurally robust and preferred for the floor construction of the present invention. Fig. 14 is an assembled cross-sectional view of the shock absorber unit 200. Fig. 14 shows a state in which two dish members 222 are stacked in the opposite direction as a buffer member 220, that is, a dish spring composed of one spring set.

The support plate 230 is installed on the cushioning member 220 to support the thermally conductive metal plate 500. At this time, the support plate 230 is formed with an insertion hole 230a through which the upper end 210a of the post 210 is inserted. 15 is a rear perspective view of the support plate 230. FIG.

As shown in FIG. 15, a guide part 232 may be provided on the back surface of the support plate 230. The guide part 232 may be formed integrally with the support plate 230 or may be installed as a separate member on the support plate 230 through welding or the like. The guide part 232 guides the upper end 210a of the post 210 so as not to be separated from the insertion hole 230a of the support plate 230. [ Therefore, the insertion hole 230a of the support plate 230 extends to the guide part 232, and the guide part 232 may have a cylindrical shape.

14, it is preferable that the upper end 210a of the post 210 is inserted into the insertion hole 230a of the support plate 230 so as to have a step difference d. Specifically, it is preferable that the upper end 210a of the post 210 is positioned at a predetermined distance d from the distal end 230a-1 of the insertion hole 230a. For example, when a strong impact is applied to the upper portion of the support plate 230, the upper end 210a of the post 210 is detached from the insertion hole 230a by the contraction of the cushioning member 220, And can be pressed onto the metal plate 500. The step (d) can prevent such a phenomenon. That is, when a strong impact is applied to the support plate 230, the step (d) forms an extra exit / exit path of the end 210a so that the upper end 210a of the post 210 and the thermally conductive metal plate 500 So that compression bonding can be prevented. The step (d) may be formed at a distance of, for example, 0.2 to 3 mm. The step (d) may be formed at a distance of 0.5 to 2 mm for another example. Specifically, when an impact is applied, the upper end 210a of the post 210 may flow in the range of 0.2 to 3 mm (or a range of 0.5 to 2 mm) inside the insertion hole 230a).

Referring to FIG. 14, a stopper 240 may be formed on the post 210. The stopper 240 protrudes at right angles from the post 210 as shown in Fig. 14, and is closely attached to the lower end of the buffer member 220. [ The stopper 240 supports the buffer member 220.

However, the thermal conductive metal plate 500 is provided according to the present invention, When the heating pipe 400 is provided on the lower side of the conductive metal plate 500, the thermal conductivity is effectively improved. More specifically, the metal plate 500, which has a higher thermal conductivity than the conventional finishing mortar, can effectively conduct and discharge heat, thereby achieving a high heating effect even with a low energy consumption amount. Further, a heat insulating material 300 is provided on the lower side of the heating pipe 400, so that the heat of the heating pipe 400 can be transferred only to the upper part by heat insulation.
