Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shock absorbing unit for floor construction of a building, and a bottom construction structure of the structure including the shock absorbing unit.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing unit for floor construction of a building and a floor construction structure including the same. More particularly, the present invention relates to an impact absorbing unit for floor construction, And a floor construction structure of a building 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, the formwork is laid on the horizontally installed steel frame, the reinforcing bars are connected to the concrete frame, and the concrete is laid and cured to construct the slab.

As mentioned above, once concrete is poured, cured, and the mold 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 floor of the building, it is very important to block the noise and vibration between the layers (lower and upper layers). The impact on the floor, especially the shock caused by the severe fluctuations of children in multi-storey buildings such as apartments, causes severe damage to residents downstairs. Accordingly, the installation of the shock absorber (shock absorber) for shock absorption and the sound insulating material for exhausting the noise can be said to be essential for the floor construction work of the building.

To this end, sound insulation / cushioning materials such as rubber material and synthetic resin foam are generally installed on the slab bottom of the building. 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 sound insulation through a hollow portion . However, it is pointed out that the installation work is somewhat complicated although the hollow portion has the sound insulation.

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

In addition, the shock absorbing unit 200 separates the thermally conductive metal plate 500 and absorbs shocks applied to the upper portion of the impact absorbing unit 200, thereby effectively blocking noise and vibration. At this time, the impact absorption unit 200 may be fixed to the isolation wall 20 of the concrete panel 100.

14 to 17 show an embodiment of a shock absorbing unit 200 according to the present invention.

14, a shock absorbing unit 200 according to the present invention includes a first substrate 210; A support rod 220 mounted on the first substrate 210; A resilient buffer member 230 inserted into the support rod 220; And a second substrate 240 provided on the buffer member 230. At this time, the shock absorbing unit 200 according to the present invention includes a plurality of support rods 220 for a sense of stability. The impact-absorbing unit 200 configured as described above effectively absorbs shocks applied from the upper portion, and buffers the shock to block noise and vibration.

Each component constituting the shock absorbing unit 200 according to the present invention may be selected from, for example, a metal material and / or a plastic material, but its modification is not particularly limited. Hereinafter, exemplary embodiments of the respective components constituting the shock absorbing unit 200 according to the present invention will be described.

The first substrate 210 is in the form of a plate, such as a circular or polygonal (square, etc.), which is fixed on the floor structure of the building. At this time, the floor structure may be selected from, for example, the concrete panel 100 as described above. More specifically, the first substrate 210 may be secured to the isolation wall 20 and / or the reinforcement 35 of the concrete panel 100. The first substrate 210 may be fixed to the concrete panel 100 through an anchor bolt 142 (see FIG. 12). For this, a bolt hole 210a into which an anchor bolt 142 can be inserted may be formed on the first substrate 210. More specifically, at least one bolt hole 210a is formed in the first substrate 210, and an anchor insert 144 is formed in the isolation wall 20 and / or the reinforcement portion 35 of the concrete panel 100 So that the anchor bolt 142 penetrates the bolt hole 210a and then is fastened to the anchor insert 144 and fixed to the concrete panel 100 on the first board 210. [

The support rods 220 have a plurality of support rods 220 for stability. That is, a plurality of support rods 220 are provided on the first substrate 210. For example, three to six support rods 220 may be provided on the first substrate 210, and four support rods 220 are arranged and spaced at predetermined intervals. The support rods 220 may have a shape of, for example, a cylindrical shape or a polygonal columnar shape.

The buffer member 230 has elasticity, which is inserted into the support bar 220 to provide a buffering force for shock absorption. The buffer member 230 is not limited as long as it has elasticity.

At this time, when the shock is applied to the upper portion of the shock absorbing unit 200, the length of the shock absorbing member 230 to be shrunk is preferably about 0.1 mm to 4 mm. More specifically, when an impact is applied to the upper portion (upper layer), the buffer member 230 is shrunk (buffered). At this time, the buffer member 230 is subjected to an impact load of about 0.1 mm to 4 mm .

For example, assuming that the total length (height) of the cushioning member 230 is about 5 cm (= 50 mm) (initial length = about 5 cm) before the impact is applied, (230) is shrunk to about 0.1 mm to 4 mm, and the length (height) after shrinkage is about 46 to 49.9 mm. At this time, when the shrinking length (shrinkage force) is less than 0.1 mm, the shock absorbing function (buffer function) may be insignificant. If the shrinkage length (shrinkage force) exceeds 4 mm and is excessively shrunk, it may be undesirable because shock (shrinkage) shaking may be felt in a person. Considering this point, the length of the buffer member 230 to be contracted is preferably 0.5 mm to 3.5 mm, or 1 mm to 3 mm. When it is cushioned in such a range, it is preferable because it has excellent shock absorbing function (buffer function) and does not give a feeling of shrinking (shock) to a person. In this case, the impact load is an arbitrary impact load that can be applied at the upper portion after the floor construction, and is not particularly limited, and in one example, it may be an impact load such that a person weighing 100 kg can jump by about 30 cm from the floor .

In the present invention, the cushioning member 230 is not limited as long as it can have the contracting force in the above range. The cushioning member 230 may include, for example, a coil spring (spring structure) have.

According to a preferred embodiment, the buffer member 230 is selected from a plurality of the gusset members 235. 15 shows a cross sectional structural view of a cushioning member 230 including a plurality of gusset members 235 as a preferred embodiment of the cushioning member 230. As shown in Fig.

Referring to FIG. 15, it is preferable that the buffer member 230 is an elastic body formed by stacking a plurality of gusset members 235 in detail. The lid member 235 may be a resilient metal member or an elastic plastic member, and may be made of a metal material such as carbon steel, stainless steel (SUS), aluminum alloy steel, and steel.

A buffer hole 235a is formed at the center of the arm member 235 and a support rod 220 is inserted into the buffer hole 235a. More specifically, the lid member 235 includes a buffer bore 235a at the center where the support bar 220 is inserted and a rib-shaped elastic disc 235b formed in the circumferential direction with respect to the buffer bore 235a. . At this time, as shown in FIG. 15, the scalloped elastic disc 235b has a sloped shape formed at an angle? With respect to the horizontal reference line L. As shown in FIG. Although the elastic disc 235b is not particularly limited, it may be formed obliquely so as to have an angle [theta] of, for example, about 2 to 45 degrees from the horizontal reference line L. [

The buffer member 230 may be formed by laminating a plurality of the lid members 235 as described above. 15, two lid members 235 are stacked in opposite directions to form one elastic body set. One or two or more elastic body sets may be stacked to form the buffer member 230 have. 15, two lid members 235 stacked in mutually opposite directions form one elastic body set, four elastic body sets are stacked on top and bottom, and a total of eight lid members 235 are stacked. 230). Therefore, when an impact is applied to the upper portion, the shade member 235, that is, the shank elastic member 235b formed obliquely at a predetermined angle (θ) spreads (spreads) to absorb and cushion the shock. This gusset member 235 implements shock absorption (buffering) more securely than a coiled spring, which is also structurally robust and preferable to the present invention.

Referring to FIG. 14, the second substrate 240 is mounted on the buffer member 230 to support the thermally conductive metal plate 500. At this time, the second substrate 240 has a plate shape such as a circular or polygonal (rectangular or the like) shape, and a guide hole 245 is formed therein. That is, a guide hole 245 through which the upper end 221 of the support rod 220 is inserted is formed in the second substrate 240. The number of the guide holes 245 may be the same as the number of the support rods 220. For example, as shown in FIG. 14, when the number of the support rods 220 is four, the number of the guide holes 245 may be four. Accordingly, when an impact is applied to the upper portion of the second substrate 240, the second substrate 240 can be moved up and down along the support rod 220.

16, the upper end 221 of the support rod 220 is inserted into the guide hole 245 of the first substrate 240 so as to have a step difference d. More specifically, the upper end 221 of the support rod 220 is preferably positioned at a predetermined distance d from the distal end 245a of the guide hole 245. For example, when a strong impact is applied to the upper portion of the second substrate 240, the upper end 221 of the support rod 220 is separated from the guide hole 245 by the contraction of the buffer member 230, The thermally conductive metal plate 500 may be squeezed. The step (d) can prevent such a phenomenon. That is, when a strong impact is applied to the second substrate 240, the step (d) forms an extra entrance / exit path of the distal end 221 so that the upper end 221 of the support rod 220 and the thermally conductive metal plate 500 Can be prevented. The step (d) may be formed at a distance of, for example, 0.2 mm to 6 mm. The step (d) may be formed at a distance of, for example, 0.5 mm to 4 mm. Specifically, when an impact is applied, the upper end 221 of the support rod 220 may flow in the range of 0.2 mm to 6 mm (or in the range of 0.5 mm to 4 mm) inside the guide hole 245).

The height adjusting member 250 is used to adjust the level between the shock absorbing units 200.

A plurality of the shock absorbing unit 200 according to the present invention may be installed on the floor of the building, and in some cases, the floor of the building may not be leveled. At this time, at least the level of the shock absorbing unit 200 can be adjusted through the height adjusting member 250. The height adjusting member 250 is, for example, a ring shape, and is fitted into the support rod 220. For this purpose, the height adjusting member 250 may be formed with a fitting hole 255 through which the support rod 220 is inserted. In one example, the height adjusting member 250 may be one or more than two. The number of the height adjusting members 250 can be determined according to the height variation. That is, depending on the height difference between the shock absorbing units 200, a height adjusting member (not shown) may be interposed between the first substrate 210 and the buffer member 230 and / or between the second substrate 240 and the buffer member 230 250) can be installed in an appropriate number to adjust the height.

17, support portions 212 and 242 may be formed on the surfaces of the first substrate 210 and the second substrate 240 that are in contact with the buffer member 230. Referring to FIG. That is, the first support 210 may be formed on the upper surface of the first substrate 210, and the second support 242 may be formed on the lower surface of the second substrate 240. The supporting portions 212 and 242 may be integrally formed from the first substrate 210 and the second substrate 240. The support portions 212 and 242 may have a ring shape and may have the same outer diameter as the intake member 235 constituting the buffer member 230. At this time, the second support portion 242 formed on the second substrate 240 has a communication hole communicating with the guide hole 245, and the upper end of the support rod 220 is fitted in the communication hole.

The cushioning member 230 can be stably brought into close contact with the first substrate 210 and the second substrate 240 by the support portions 212 and 242 and the support portions 212 and 242 The height adjustment function can also be combined. In addition, in the case of the second support 242 formed on the second substrate 242, the length of the guide hole 245 can be extended to guide the upper end 221 of the support rod 220 in a stable manner . More specifically, the second support portion 242 may be formed with a communication hole as described above, so that the length of the guide hole 245 formed in the second substrate 240 can be extended. Accordingly, it is possible to effectively prevent the upper end 221 of the support rod 220 from being detached from the guide hole 245 of the second substrate 240.
