Description

[0001] The present invention relates to a hollow body having a buffer layer and a hollow slab including the hollow body,

The present invention relates to a hollow body having a buffer layer and a hollow slab including the same, and more particularly to a hollow slab having a buffer layer disposed between an upper unit and a lower unit of a hollow body used for hollow slabs, The present invention relates to a hollow body having a buffer layer and a hollow slab including the buffer layer so that rigidity can be increased by constructing upper and lower units of the body in a diaphragm structure.

The wall structure of the apartment house is superior to the floor impact, workability and economical efficiency, but is relatively disadvantageous to the heavy impact sound due to the large influence by the vibration of the vertical member (wall). In addition, the laminated structure is advantageous for heavy impact sound because of reduction of vibration caused by reduction of vertical members and flexural rigidity of beams, but it is often disadvantageous to increase of floor height, workability and economy. In addition, the flat plate structure is advantageous for the reduction of floor height, variability and long span. However, since the details of the structure for securing the vibration performance due to long span, the weight of the bottom plate and the shearing performance are complicated, Is rather disadvantageous.

In recent years, various methods have been put into practice to increase the strength of the building by increasing the thickness of the slab to increase the height of the building or to secure a spacious living room, or to hollow the inside of the slab in order to improve the weight and sound insulation performance .

Such a hollow core slab has a hollow structure or a lightweight structure buried in the center thereof. As the weight of the panel is reduced, the weight of the slab is reduced, and the hollow core slab has comparatively excellent sectional performance. Such a hollow slab has a long span The advantages of the flatslab are advantageous for reducing the interlayer noise.

The hollow slab can be divided into a ball type and a crater type, and the method applied in Korea is not much different from the conventional method, and there is a technical difference in development of a device for preventing buoyancy.

In recent years, applications of hollow slabs using decks and removable dies have also increased. Specifically, the hollow slab is provided with a slab formwork on the site, the formwork is supported by a supporting member such as a horseshoe, a slab bottom reinforcing bar and a lower wire mesh are disposed on the slab formwork, a hollow body is disposed on the lower wire mesh, The upper wire mesh and the upper reinforcing steel are placed on the hollow body, and then the slab concrete is installed.

These hollow slabs are known to have better performance than impact slabs in comparison with conventional slabs, but the performance of the hollow slabs is lowered in the 63 Hz band. In addition, countermeasures to prevent buoyancy are required, and the cost may increase depending on the manufacturing method.

In addition, the hollow slab has many advantages such as fireproof performance, lowering of workability due to buoyancy of hollow body when concrete is poured, manufacturing cost increase due to increase of factory production of unit module such as wire mesh processing, And the efficiency of the house is reduced. In order to reduce the interlayer noise, a hollow slab system that can be applied to a column type is required. However, in the case of the hollow slab developed in the past, performance is lowered in some frequency bands (63-125 Hz) In many cases, the efficiency of construction is deteriorated when applied to an apartment flat.

Therefore, it is necessary to develop a long-span, lightweight floor system that dramatically reduces floor-to-floor noise and improves construction efficiency in order to switch to a column type that is superior in structure, construction and interlayer noise compared to a wall type.

FIG. 1A is an exploded view for explaining a hollow body according to the first embodiment of the present invention, and FIG. 1B is a perspective view of the hollow body of FIG.

Referring to FIGS. 1A and 1B, a plurality of hollow bodies 100 according to the first embodiment of the present invention are installed at regular intervals between an upper reinforcing bar and a lower reinforcing bar. The hollow body 100 according to the embodiments of the present invention includes a lower unit 110, a lower unit 110, and a lower unit 110 installed on a form bottom surface or an upper portion of the lower reinforcing bar before hollow slab construction, And an upper unit 120 coupled to the lower unit 110 at an upper portion thereof and having a hollow therein. That is, the hollow body 100 has an outer appearance of a hexahedron in which the inside is hollow, and has a structure in which the top and the bottom of the hexahedron are separated. Accordingly, the hollow body 100 is composed of the lower unit 110 and the upper unit 120 having hollows therein, and can be used in the construction of the hollow slab type slab.

In addition, the lower unit 110 and the upper unit 110 of the hollow body 100 are formed of the diaphragm 112 formed to cross the inner hollow, and the rigidity is improved. The diaphragm 112 of the hollow body 100 according to the embodiments of the present invention is not limited to a specific structure and may be adjusted according to various conditions and environments such as the size and length of the hollow body 100. [ However, in the case where the diaphragm 112 is present, the stiffness of the hollow body 100 will be relatively higher due to the wall structure, the wall, and the column, as compared with the case where the diaphragm 112 does not exist in the hollow body 100.

In the embodiments of the present invention, the hollow body 100 includes a buffer layer 130 located between the upper unit 120 and the lower unit 110 and composed of a cushioning material absorbing vibration and noise.

The buffer layer 130 is made of a material capable of absorbing vibration and noise. The buffer layer 130 may be formed in the form of a plate, a bar extending in the longitudinal direction, or the like.

For example, when the buffer layer 130 is formed in the form of a plate, the buffer layer 130 may be bonded to the lower unit 110 and the upper unit 120 in an edge region where the lower unit 110 and the upper unit 120 contact with each other. . That is, the upper unit 120 is adhered to the upper surface edge of the buffer layer 130 along the periphery of the plate-shaped buffer layer 130, and the lower unit 110 is bonded to the lower edge of the buffer layer 130.

In another example, the buffer layer 130 is formed in a plate shape, and the coupling hole 134 formed by penetrating one region of the buffer layer 130 is located, and the lower unit 110 and the upper unit 120 are connected to the buffer layer 130 And a first coupling means 114 and a second coupling means 116 which can be coupled through the coupling hole 134. Meanwhile, the first coupling means 114 and the second coupling means 116 may be coupled to each other by a combination of a male-male coupling and a bolt-nut coupling. The first engaging means 114 according to embodiments of the present invention are formed at a point where the diaphragm 112 of the lower unit 110 intersects and the second engaging means 116 is formed at a position where the diaphragm of the upper unit 120 And the first coupling means 114 and the second coupling means 116 may be coupled to each other through the coupling hole 134 of the buffer layer 130. [ Accordingly, the rigidity of the hollow body 100 can be greatly increased due to various coupling structures.

As described above, when the bottom surface (or the ceiling surface) is constructed by the hollow slab method, the hollow body 100 is provided with the buffer layer 130 made of a separate buffer material to further absorb vibration and noise, .

FIG. 2A is an exploded view for explaining a hollow body according to the second embodiment of the present invention, and FIG. 2B is a perspective view of the hollow body of FIG.

Referring to FIGS. 2A and 2B, the hollow body 100 according to the second embodiment of the present invention has a rectangular parallelepiped structure longer in one direction than the hollow body shown in FIGS. 1A and 1B. The overall structure and structural characteristics of the hollow body 110 are substantially the same as those of the hollow body 110 except for the overall appearance, size and length of the hollow body 110.

The lower unit 110 and the upper unit 120 are hollow and have a diaphragm 112 formed across the hollow. The number of diaphragms in the hollow body 100 according to the second embodiment will be larger than the number of diaphragms of the hollow body 100 according to the first embodiment. The number of the diaphragms 112 is increased so that the number of the coupling holes 134 of the buffer layer 130 is increased and the number of the coupling holes 134 is increased. The number of the coupling means 114 and 116 for coupling the lower unit 110 and the upper unit 120 through the through holes may be increased.

The number of the diaphragms 112 and the number of the coupling means 114 and 116 can be controlled to increase the strength and reduce the interlayer noise even if the size or shape of the hollow body 100 changes. Meanwhile, since the size and shape of the hollow body 100 can be changed, the hollow body 100 can be applied to the construction in various environments.

FIG. 3 is an exploded view for explaining a hollow body according to the third embodiment of the present invention, and FIG. 4 is a rear view of the hollow body of FIG. 3 coupled.

3 and 4, the hollow body according to the third embodiment of the present invention has the same shape and structure as the hollow body described above, with the lower unit 110 and the upper unit 120 having hollows therein .

The buffer layer 132 according to the third embodiment of the present invention has a shape corresponding to the inner hollow of the lower unit 110 and the upper unit 120, That is, the buffer layer 132 is made of a material such as styrofoam that can absorb vibration and noise while being filled in the hollows of the lower unit 110 and the upper unit 120. When there is a diaphragm in the hollow of the lower unit 110 and the upper unit 120, the buffer layer is individually filled in the hollows separated by the diaphragm. When the diaphragm is absent, the lower unit 110 and the upper unit 120 will be filled.

For example, when the buffer layer 132 is filled in the hollows of the lower unit 110 and the upper unit 120, the lower unit 110 is provided with an inner bottom surface 110 for coupling the lower unit 110 and the upper unit 120, And the upper unit 120 is provided with a fourth coupling means 116 provided on the inner upper end surface thereof. The third coupling means 114 and the fourth coupling means 116 may be coupled to each other through the coupling holes provided in the buffer layer 132 to increase rigidity.

Generally, a plurality of hollow bodies 100 spaced apart from each other at regular intervals are bundled into a group. In this case, it is necessary to keep the gap between the hollow bodies constant and at the same time to bond the hollow bodies together, so that the floating of the specific hollow body by buoyancy during the construction is prevented.

Therefore, in the embodiments of the present invention, the hollow body 100 may further include spacers 140 and 142 for simultaneously realizing the spacing and coupling between the hollow bodies 100.

The first gap member 140 has a configuration (hook) that is fitted in the gap hole 126 provided in the side surface 127 of the upper unit 120 so as to be inserted into the gap hole 126 of the adjacent upper unit 120 So that the coupling between the hollow bodies 100 can be maintained while maintaining the spacing in a manner to be fitted. For example, the first spacers 140 may be formed in a ladder shape.

The second gap member 142 is positioned in a region where the lower unit 110 and the upper unit 120 are in contact with each other to maintain the gap between the adjacent hollow bodies 100 and the coupling. That is, the second spacers 142 may be in the form of a bar to be connected to the adjacent hollow body 100 at a middle height of the hollow body 100.

Although the first gap member 140 and the second gap member 142 are separately described, the first gap member and the second gap member may be replaced with each other, Only the second spacers can be applied.

5 and 6, a hollow body 100 according to an embodiment of the present invention has an opening and has an opening in which the lower unit 110 and the upper unit 120 are connected to each other, A belt 160 coupled to the upper unit 120 and a belt 160 positioned between the belt 160 and the lower unit 110 or between the belt 160 and the upper unit 120, And further includes a gap bar 150 extending to the adjacent hollow body to adjust the gap.

The hollow body 100 according to another embodiment of the present invention has an opening and includes a lower unit 110 and an upper unit 120 in an edge region where the lower unit 110 and the upper unit 120 contact with each other, And a gap bar 150 for extending the gap between adjacent hollow bodies 100 through one side of the band plate 160 to control the gap between the hollow bodies 100 do.

By using the spacing bars 150 having the same length as that of the strip 160 provided in the hollow body 100 at the same position in the hollow body 100 or maintaining the same interval at the time of construction, Construction is possible.

The fixed frame portion 172 has the same structure as that of the hollow body 100 to stably fix the hollow body 100 so that the hollow body 100 does not move. And has a structure for stably fixing and supporting to other fixtures. The space frame portion 176 refers to a space that surrounds the hollow body 100. The space occupied by the space frame portion 176 allows the installer (user) to efficiently install electric wires and other facility pipes using the space.

On the other hand, since the purpose of the hollow slab to achieve weight reduction is the top priority, the material of the frame portion 170 is preferably made of a relatively light material.

Particularly, the frame part 170 according to the embodiments of the present invention is divided into upper and lower parts, and the lower end part and the upper end part are assembled (combined). As shown in the figure, the upper and lower sides of the fixed frame portion 172 may be divided based on the cut line in the middle of the fixed frame portion 172. The lower end portion of the frame portion 170 including the support frame portion 174 is stably fixed to the mold and only the lower end portion of the fixed frame portion 172 is provided in the region where the hollow body 100 is to be positioned, The body 100 is easily seated in the corresponding region of the fixed frame portion 172. [ When the upper end of the fixed frame part 172 is assembled from the upper part in a state where the hollow body 100 is seated, the hollow body 100 is also fixed and the remaining space of the fixed frame part 172 Area) can facilitate other construction work.
