Description

Floor support structure in building {FLOOR SUPPORT STRUCTURE FOR BUILDING}

The present invention provides a floor support structure in a building, particularly a floor support structure in a building having a concrete sphere having a fixed structure in which a floor slab is connected to an upper surface of a beam. The present invention also relates to a floor support structure of a building having a concrete sphere having a quantitative structure in which floor slabs are connected to upper surfaces of bulk and small beams.

In general, in an assembly house such as a mansion, since the floor structure is fixedly coupled to the floor slab of the concrete sphere or the concrete wall, the vibration impact sound applied to the floor or the like is a solid wave sound. There is a problem that the sound is transmitted from the floor structure to the upper and lower floors and the left and right sides as vibrating noise, which causes deterioration of the environment of the living space, deterioration of quality, and the like. In particular, in recent years, Japanese-style rooms have been reduced due to changes in lifestyle, and western-style rooms have a flooring floor that is difficult to be a cushioning material. Is changing, the vibration noise transmitted from the floor structure to the upper and lower layers and the left and right sides tends to be further increased, and the sound insulation countermeasure is a major problem.

Therefore, conventionally, countermeasures such as increasing the thickness of the floor slab or making the floor structure itself a sound insulation structure have been taken as measures for sound insulation.

However, even if the measures against such sound insulation are taken, the contact state between the floor structure and the concrete sphere, in particular the floor slab, cannot be avoided. Thus, even if the propagation of vibration noise can be reduced, there is a problem of not being a fundamental sound insulation measure. There is another problem that causes a significant increase in costs.

In order to solve such a problem, the present invention ensures insulation between the floor structure and the concrete sphere, changes the living noise from the solid wave sound to the air wave sound, and greatly improves the sound insulation performance. It is also an object of the present invention to provide a floor support structure in a new building, which enables a more simple structure to support the floor structure to the sphere more stably.

In addition, the present invention avoids the floor structure from contact with the floor slab and improves the concrete sphere itself, so that even when the floor area of the floor structure is large, the vibration noise applied to the floor structure is efficiently spread to the concrete sphere. It is possible to improve the sound insulation effect, and at the same time increase the support strength of the floor structure to the concrete sphere, so that the floor support structure in the new building can be stably supported by the concrete sphere.

Further, the adoption of the floor support structure does not reduce the effective indoor space on the floor. In addition, in the floor slab, the floor slab does not act as a load and does not need to have a sound insulation function, so that the floor slab can be made as thin as possible than the slab thickness of the conventional floor slab.

The horizontal sphere portion Fh is provided with a bottom slab Sf which partitions the living space Dw up and down (it can be thinner than the conventional one by the features of the present invention). On both left and right sides of Sf, a positive mass Bb is provided so as to integrally project downward, and is constituted of a so-called "fine structure". Moreover, the said vertical structure part Fv is the vertical concrete wall 2 and 3 which connects the concrete pillar 1 installed upright in four corners of the living space Dw, and the concrete pillar 1 arrange | positioned in parallel. ).

The floor structure Fr is provided on the floor slab Sf of the living space Dw of each floor.

Since the floor structure Fr has the same structure as each layer, the following describes one of the floor structures Fr, and the floor structure Fr is the floor slab Sf of the concrete sphere F. ) Is supported by the vertical sphere walls 2, 3, by avoiding direct contact with it.

On the bottom slab Sf of the concrete sphere F, a plurality of girder beams 5... Are arranged in parallel in parallel to each other on one plane, with a slight gap D1 in the vertical direction over the entire area thereof. Both ends of the girder beams 5... Are integrally coupled by left and right beam receivers 8, 8 extending perpendicular to the girder beams 5..., And the plurality of girder beams 5. It is formed in the closed frame shape by 8), and the floor structure Fr is reinforced.

Each girder beam 5 is formed by forming a steel plate such that its cross section is bent in a ∑ shape, thereby forming a light weight while ensuring sufficient rigidity. In addition, as shown clearly in FIG. 4, the beam receiving part 8 is formed by the angled equilateral angular shaped steel of a cross section, and has the horizontal half part 8h and its one end part. It consists of a vertical half part 8v falling down from the horizontal half part 8h, which is fixed to the upper surface of the end of the girder beam 5 through the anti-vibration rubber 14 by the bolt nut 10, and The vertical half portion 8v extends downward to cross the cross sections of the plurality of girder beams 5..., So that the plurality of anchor bolts 12 are arranged between the neighboring girders 5, 5. It is fixed to the vertical sphere walls 2 and 3, respectively. Therefore, the plurality of girder beams 5... Which are provided with the gap D1 on the bottom slab Sf are vertical through the dust-proof rubber 14 and the beam receiving part 8 with their gaps having the gap D2. Supported by the spherical walls 2, the plurality of girder beams 5... Are not in direct contact with the bottom slab Sf and the vertical spherical walls 2, 3.

It is possible to make it as thin as possible (about 10 to 15 cm), thereby making it possible to increase the indoor height of the living space Dw, and also to reduce the weight of the concrete sphere F and to improve the seismic and vibration damping performance. In addition, a significant cost reduction of the building itself can be achieved by reducing the amount of concrete and steel used.

In addition, since the bottom structure Fr can be supported by the vertical concrete wall 2 below the upper plate 7, a member for supporting the bottom structure Fr above the bottom structure Fr is provided. It does not exist, and furthermore, the finishing concrete wall 2 can be directly attached to the vertical sphere wall 2, thereby ensuring a wide indoor space. In addition, the beam receiving bodies 8 and 8 are fixed to the upper end surface of the some girder beam 5 ..., and do not protrude below the lower surface of the girder beam 5 .... The gap D1 between the girder beam 5... And the bottom slab Sf can be set to a minimum necessary limit, and as a result, the occupation height of the subfloor space does not increase.

As described above, according to the first aspect of the present invention, the floor structure and the floor slab are insulated, that is, contact between them is avoided, and the propagation to the upper and lower layers and the left and right sides of the vibration noise generated in the floor structure is reduced as much as possible. The sound insulation effect can be improved. In particular, by supporting both ends of the plurality of girder beams constituting the floor structure on the vertical concrete wall, the vibration noise applied to the floor structure is distributed and propagated in the vertical and horizontal directions of the vertical concrete wall through the plurality of girder beams, and then The effect can be improved and, in addition, the floor structure can be stably supported. In addition, the adoption of the floor support structure does not reduce the effective indoor space of the living space. Moreover, in the floor slab, since the load of the floor structure does not work and it does not need to have a sound insulation function, it becomes possible to make this floor slab as thin as possible than the slab thickness of the conventional floor slab, thereby living space It is possible to increase the effective height of the concrete, reduce the weight of the concrete sphere, improve the seismic and vibration damping performance, and reduce the amount of concrete or steel used, thereby achieving significant cost reduction of the building itself. .

A plurality of inserts 119 are integrally embedded in the side surface of the concrete receiving beam 4 opposite to the support member 117, and the attachment bolt 121 penetrating the long hole 118 through the washer 120 is provided. By fastening with screws to the insert 119, the plurality of support members 117 is fixed to the side of the concrete receiving beams 4 in a vertically adjustable position. On the horizontal half part 117h of the some supporting member 117, the said beam support 8 is mounted on the anti-vibration rubber 122, and is installed.

As shown in FIG. 16, the several girder beams 5 ... are supported by the above-mentioned bolt nut 113 between the support members 117 which adjoin each other to the beam receiving body 8. As shown in FIG. The gap D2 is formed between the ends of the plurality of girder beams 5... And the side surfaces of the concrete receiving beams 4, and the lower surface and bottom slab Sf of the girder beams 5. The space | gap D1 is formed between and, and the several girder beams 5 ... do not directly contact the concrete support beam 4 and the bottom slab Sf by this.

As shown in FIG. 11, FIG. 12, in the some girder beam 5 ..., several joists 6 ... which are formed orthogonal to them and formed by the wooden angled pillar material etc. are laid in parallel, and they On the joist line 6..., An upper plate 7 made of a flooring plate or the like is placed, and the upper plate 7 is avoided from contacting the concrete receiving beams 4.

In addition, as shown in FIG. 14, the support structure with respect to the vertical spherical wall 2 of the other end part of several girder beam 5 ... is the concrete receiving beam 4 of the one end part of the said girder beam 5 ... Since it is the same as the support structure for the description thereof will be omitted.

The plurality of girder beams 5... Which are provided with the spaces D1 on the bottom slab Sf have their concrete ends via the dustproof rubber 114 and the beam support 8 with their ends having the spaces D2. The girder beams 5...

In addition, by reducing the amount of concrete or steel used, significant cost reduction of the building itself is achieved.

In addition, since the bottom structure Fr can be supported by the concrete support beam 4 or the vertical concrete wall 2 below the upper plate 7, the bottom structure Fr is above the bottom structure Fr. A member for supporting (Fr) does not exist, and further, the finishing wall material can be directly attached to the vertical sphere wall 2, thereby ensuring a wide indoor space. In addition, the beam receivers 8 and 8 are fixed to the upper end surfaces of the plurality of girder beams 5..., So that they do not protrude downward from the lower surface of the girder beams 5. The gap D1 between the bottom slab Sf and the bottom slab Sf can be set to a minimum necessary limit, and as a result, the occupation height of the underfloor space does not increase.

As described above, according to the fourth embodiment according to the present invention, in a building having a concrete sphere having a quantitative structure in which floor slabs are connected to the upper surfaces of large and small beams, the floor structure and the floor slab are insulated, that is, their The contact is avoided, and the sound insulation effect can be improved by reducing the propagation of the vibration noise to the upper and lower floors and the left and right sides as much as possible. In particular, the girder beams constituting the floor structure are interposed between the concrete support beams or the concrete support beams. By supporting between the beam and the vertical concrete wall, the vibration noise applied to the floor structure having a large floor area is distributed and propagated to the concrete sphere through the concrete support beam on the floor slab or the vertical concrete wall, thereby further improving the sound insulation effect. And, moreover, can stably support the floor structure. In addition, the adoption of the floor support structure does not reduce the effective indoor space on the floor. In addition, since the load of the floor structure does not act on the floor slab and does not have a sound insulation function, the floor slab can be made as thin as possible than the slab thickness of the conventional floor slab. The effective height of the space can be increased, the weight of the concrete sphere can be reduced, and the seismic and vibration damping performance can be improved, and the reduction in the amount of concrete or steel used can significantly reduce the cost of the building itself. Is achieved.

Next, a fifth embodiment of the present invention will be described with reference to FIGS. 17 and 18.

In this fifth embodiment, the same reference numerals are attached to the same ones as the fourth embodiment.

In this fifth embodiment, the support structure of the girder beam 5... To the concrete support beam 4 (vertical concrete wall 2) is slightly different from the first embodiment. The ends of the plurality of girder beams 5... Arranged in parallel to each other on one plane are integrally joined by beam receivers 8 extending perpendicular to them. The beam receiving body 8 is formed by an angle-shaped equilateral shaped steel having a cross section, and its horizontal half portion 8h is provided with an anti-vibration rubber 131 by bolts and nuts 130 on the upper end surface of the girder beam 5. It is fixed through, and its vertical half portion 8v extends downwardly across the cross sections of the plurality of girder beams 5..., So that a plurality of anchor bolts are arranged between neighboring girder beams 5, 5. 132 is respectively fixed to the upper side of the concrete receiving beam (4). Therefore, the plurality of girder beams 5... Which are provided with the spaces D1 on the bottom slab Sf are provided through the dustproof rubber 131 and the beam receiving body 8 with their ends having the spaces D2. It is supported by the concrete support beam 4, and the several girder beams 5 ... do not directly contact the bottom slab Sf and the concrete support beam 4 by this.

However, this fifth embodiment also has the same operational effects as the fourth embodiment.

Next, a sixth embodiment of the present invention will be described with reference to FIG.

In this sixth embodiment, the same reference numerals are attached to the same ones as the fourth and fifth embodiments.

The sixth embodiment forms a gap s with a predetermined width between the lower surface of the concrete support beam 4 and the upper surface of the bottom slab Sf, thereby receiving the load applied to the floor structure Fr. It is a case where it is made to receive by the beam 4 (vertical concrete wall 2), and on the occasion of formation of this clearance | interval s, this concrete receiving beam 4 is made into concrete by the frame combination of a mold (not shown). When pouring with spherical body F, the foamed styropol material 140 is interposed between the concrete support beam 4 and the bottom slab Sf in advance, and thereafter, the foamed styropole 140 is formed. To be removed by incineration or the like.

As described above, according to the sixth embodiment according to the present invention, the concrete receiving beams 4 and the bottom slab Sf are brought into contactless state through the air gap s, and the vibration shocks applied to the concrete receiving beams 4 are made. Is not propagated to the small beams Bs, but is dispersed and propagated to the concrete spheres F from the concrete receiving beams 4 (vertical sphere walls 2). In addition, since the beam support can be supported on the concrete support beam or the vertical sphere wall, the girder beam can be supported on the concrete support beam or the vertical sphere wall regardless of the position of the girder beam, and also the concrete support beam of the girder beam Or the position adjustment of the up-down direction with respect to a perpendicular | vertical sphere wall can be performed precisely and easily.

As mentioned above, although the 1st Example-6th Example of this invention were described, various Examples are possible within the scope of the present invention, without being limited to these Examples.

For example, in the said Example, although the case where the floor support structure in the building which concerns on this invention was given to the collective house was demonstrated, this can be implemented also in other concrete buildings. Moreover, as a top board of a floor structure, use of a tatami floor and other well-known things other than a flooring board is possible.
