Description Floor support structure in buildings

Field of the invention

The present invention relates to a floor support structure for a building, particularly a floor support structure for a building having a concrete skeleton of a regular beam structure in which a floor slab is connected to the upper surface of a beam, and a floor slab on the upper surface of a girder and a small beam. The present invention relates to a floor support structure for a building having a concrete beam frame structure to be connected.

Background art

In general, in apartment buildings such as condominiums, the floor structure is fixedly connected to the concrete slab and the slab wall of the concrete frame in a state of contact. There is a problem that vibration noise is transmitted from the body to the upper and lower floors and the adjacent rooms on the left and right sides, causing deterioration of the living space environment and quality deterioration.In particular, recently, changes in lifestyle have reduced the number of Japanese-style rooms, However, there has been a change in the occupants' occupancy from carpet floors, which function as cushioning materials, to flooring floors, which are unlikely to be cushioning materials. There is a tendency to be large, and sound insulation measures are a major issue.

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

However, even if such sound insulation measures are taken, the state of contact between the floor structure and the concrete frame, especially the floor slab, cannot be avoided, and even if the transmission of vibration noise can be reduced, drastic sound insulation measures must be taken. There is another problem that it is not possible to do so, and there is a significant increase in construction costs.

Disclosure of the invention

In order to solve such a problem, the present invention secures insulation between the floor structure and the concrete structure, changes living noise from solid-borne sound to air-borne sound, significantly improves sound insulation performance, and The objective of the present invention is to provide a floor support structure for a new building that has a simple structure and can more stably support the floor structure to the frame. Further, the present invention avoids the floor structure from coming into contact with the floor slab and improves the concrete frame itself so that even if the floor area of the floor structure is large, the vibration and noise applied to the floor structure can be improved. In order to improve the sound insulation effect, to increase the support strength of the floor structure to the concrete body, and to stably support the floor structure to the concrete body. did

Another object is to provide a floor support structure in a new building.

As a result, the sound insulation effect can be improved. In particular, by supporting both ends of a plurality of large beams constituting a floor structure on a vertical frame wall, vibration noise applied to the floor structure is reduced by a plurality of large beams. By dispersing and propagating vertically and horizontally, the sound insulation effect can be enhanced, and the floor structure can be stably supported. In addition, the use of the floor support structure does not reduce the effective indoor space on the floor. Furthermore, since the load of the floor structure does not act on the floor slab and the floor slab does not have a sound insulation function, the floor slab is made as thin as possible than the slab thickness of the conventional floor slab. As a result, the effective height of the living space can be increased, the weight of the concrete frame can be reduced, and the seismic and vibration control performance can be improved.

By reducing the cost, the cost of the building itself can be significantly reduced.

Further, the present invention relates to a building having a concrete frame with a regular beam structure in which a floor slab is connected to the upper surface of a girder and a small beam. The concrete beams are integrally laid horizontally, and the concrete beams are vertically arranged in tandem with the small beams, and a vibration-isolating rubber is interposed between the concrete beams and the floor slab. A fourth feature is that a large beam disposed on the floor slab with a gap is supported between the frame walls.

According to the configuration of the fourth aspect, the floor structure and the floor slab are insulated, that is, their contact is avoided, and the propagation of the vibration noise to the upper and lower floors and the right and left adjacent rooms is minimized. In particular, by supporting a plurality of large beams constituting the floor structure between the concrete receiving beams or between the concrete receiving beams and the vertical frame walls, Vibration noise applied to a floor structure with a large floor area can be dispersed and propagated to the concrete frame via a concrete beam on the floor slab or a vertical frame wall, further improving the sound insulation effect. Thus, the floor structure can be stably supported. In addition, the use of the floor support structure does not reduce the effective indoor space on the floor. Furthermore, since the load of the floor structure does not act on the floor slab and it is not necessary to provide a sound insulation function, the floor slab should be made as thin as possible than the slab thickness of the conventional floor slab. This makes it possible to increase the effective height of the living space, further reduce the weight of the concrete frame, improve seismic resistance and vibration control performance, and furthermore, By reducing the amount of steel used, the cost of the building itself can be significantly reduced.

It is possible to improve the sound insulation effect by reducing the number of beams.Particularly, by supporting a plurality of large beams constituting the floor structure between the concrete beams or between the concrete beams and the walls of the vertical body, the floor area is large. Vibration noise added to the floor structure can also be dispersed and propagated to the concrete frame via the concrete beam on the floor slab or the vertical frame wall, further enhancing the sound insulation effect. Can be stably supported. In addition, the use of the floor support structure does not reduce the effective indoor space on the floor. Furthermore, since the load of the floor structure does not act on the floor slab and the floor slab does not have a sound insulation function, the floor slab should be made as thin as possible than the slab thickness of the conventional floor slab. This makes it possible to increase the effective height of the living space, further reduce the weight of the concrete frame, improve seismic resistance and vibration control performance, and furthermore, By reducing the amount of steel used, the cost of the building itself can be significantly reduced.

BEST MODE FOR CARRYING OUT THE INVENTION

First, a first embodiment of the present invention will be described with reference to FIGS.

The concrete frame F with a regular beam structure, which forms the framework of an apartment house, extends in the horizontal direction, and a horizontal frame portion Fh that divides the building into multiple levels, and a horizontal frame portion that extends in the vertical direction, and And a vertical body part FV that interconnects Fh.

The horizontal frame portion Fh is provided with a floor slab Sf (which can be made as thin as possible than the conventional one), which partitions the living space Dw up and down. On both sides, a main beam Bb is protruded downward and integrally, so as to form a so-called “main beam structure”. Further, the vertical frame portion Fv includes a frame column 1 erected at the four corners of the living space Dw, and vertical frame walls 2, 3 connecting the parallel frame columns 1. I have.

A floor structure Fr is arranged on the floor slab S f of the living space Dw of each level. Since the floor structure Fr has the same structure at each level, one of the floor structures Fr will be described below. This floor structure Fr is a floor slab S of a concrete frame F. Direct contact with f is avoided, and it is supported by the vertical body walls 2,2. On the floor slab S f of the concrete frame F, a plurality of heavy beams 5 ... are arranged in parallel on one plane in parallel with each other with a slight gap D1 in the vertical direction over the entire area. Both ends of the large beam 5 ... are orthogonally connected to the large beam 5, and are integrally connected by left and right beam receivers 8, 8, and a plurality of large beam 5, right and left beam receivers It is formed in a closed frame shape by 8, 8, and the floor structure Fr is reinforced. Each pulling beam 5 is formed by bending a steel plate into a horizontal cross section ∑, and is formed to be lightweight while securing sufficient rigidity. As shown clearly in FIG. 4, the beam receiver 8 is formed of an equilateral angle steel having an angled cross section, and has a horizontal half 8h and a vertical half hanging downward from one end thereof. 8 V, and the horizontal half 8 h is fixed to the upper surface of the end of the large beam 5 via a vibration isolation rubber 14 by a port nut 10, and the vertical half 8 v is , Extending downward across the end face of the plurality of pulling beams 5, and fixed to the vertical wall 2, 2 with a plurality of anchor ports 12 between the adjacent pulling spaces 5, 5. ing. Therefore, the plurality of large beams 5 arranged on the floor slab S f with a gap D 1 are provided at both ends thereof with a gap D 2 and a vibration isolating rubber 14 and a beam receiver 8. Thus, the plurality of heavy beams 5 are not in direct contact with the floor slab S f and the vertical body walls 2, 2.

A plurality of joists 6… which are formed of a prism material such as a wood, and which are substantially orthogonal to these, are laid in parallel with each other on the plurality of pulling beams 5. A floor plate 7 made of a flooring material or the like is laid.

In particular, the vibration noise caused by the load applied to the floor structure Fr is reduced by supporting the ends of the plurality of large beams 5. … Can be dispersed vertically and horizontally along the vertical frame walls 2, 2 of the concrete frame F. In addition, since the load of the floor structure Fr does not act on the floor slab S f and it is not necessary to provide a sound insulation function, the floor slab S f is replaced with the slab thickness (2) of the conventional floor slab. (0-27 cm) as much as possible (approximately 10-15 cm), which makes it possible to increase the room height of the living space Dw, By reducing the weight of F, seismic resistance and vibration control performance can be improved, and by reducing the amount of concrete and steel used, the cost of the building itself can be significantly reduced.

Further, since the floor structure Fr can be supported by the vertical frame wall 2 below the floor plate 7, the floor structure Fr is supported above the floor structure Fr. There is no such member, and a finishing wall material can be directly adhered to the vertical frame wall 2, so that a wide indoor space can be secured. The beam receivers 8, 8 are fixed to the upper surfaces of the ends of the plurality of large beams 5, and do not protrude below the lower surfaces of the large beams 5. The gap D 1 between the floor slabs S f can be set to the minimum necessary, and as a result, the occupation height of the underfloor 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 from each other, that is, the contact between them is avoided, and the vibration noise generated in the floor structure is transmitted to the upper and lower floors and the right and left adjacent rooms. Propagation can be reduced as much as possible to improve the sound insulation effect. In particular, by supporting both ends of the plurality of large beams constituting the floor structure on the vertical body wall, the vibration noise applied to the floor structure is increased and decreased above and below the vertical body wall via the plurality of large beams. The sound can be effectively dispersed by laterally dispersing the sound, and the floor structure can be stably supported. In addition, the use of the floor support structure does not reduce the effective indoor space of the living space. Furthermore, since the load of the floor structure does not act on the floor slab, and the floor slab does not have a sound insulation function, it is necessary to make the floor slab as thin as possible than the slab thickness of the conventional floor slab. Enabled, this As a result, the effective height of the living space can be increased, the weight of the concrete frame can be reduced, the seismic resistance and vibration control performance can be improved, and the use of concrete and steel materials can be reduced. However, significant cost reduction of the building itself is achieved.

In the middle part of the suspension rod 22, a tension adjusting hardware with a vibration isolating rubber 26, that is, a turnbuckle 25 is interposed, and the length of the suspension rod 22 is adjusted by adjusting the turnbuckle 25. That is, the tension is adjusted.

However, since the middle part of the large beam 5 is suspended and supported by the hanging rod 22, the deflection of the large beam 5 can be prevented, especially when the span of the large beam 5 is long. The main load applied to 5 is received by the left and right vertical body walls 2 and 2 as in the first embodiment, and the large beam 5 is prevented from contacting with the floor slab S f, and vibrates to the upper and lower floors and the left and right adjacent rooms Noise propagation can be reduced as much as possible.

Since the floor structure Fr has the same structure on each floor, the support structure of the floor structure Fr will be described below with reference to FIGS. 11 and 12 and FIGS. In detail, this floor structure Fr is prevented from being in direct contact with the floor slab Sf of the concrete frame F, and is arranged in parallel between the vertical frame wall 2 and the concrete receiving beam 4 or at an interval. Between the concrete receiving beams 4.

On the floor slab S f of the concrete frame F, a plurality of heavy beams 5 ... are arranged in parallel on one plane in parallel with each other with a small gap D1 in the vertical direction over the entire area. Both ends of the pulling beams 5 are fixedly supported between the concrete receiving beams 4 or between the concrete receiving beams 4 and the vertical wall 2 as clearly shown in FIG. Since the supporting structure of the large beam 5 on the concrete beam 4 is the same as the supporting structure of the vertical beam wall 2, the supporting structure of the large beam 5 on the concrete beam 4 will be described in detail below. .

As is clearly shown in FIG. 15, the beam receiver 8 is formed of an equilateral angle steel having an angled cross section, and has a horizontal half 8 h and a vertical half 8 V hanging downward from one end thereof. The horizontal half 8 h is fixed to the upper surface of the end of the large beam 5 by the port nut 11 1 via anti-vibration rubber 1 14, and the vertical half 8 V Extends upward so as to face the side surface of the concrete beam 4, and another anti-vibration rubber 115 is interposed between them.

On the other hand, as shown in FIGS. 15 and 16, a plurality of support members 117 are fixed to the side surface of the concrete receiving beam 4 so as to be vertically adjustable. Each support member 117 is made of an equilateral angle steel having an angled cross section, and a vertically long elongated hole 118 is formed at the center of the vertical half portion 117V. On the side of concrete beam 4, A plurality of inserts 1 19 are embedded in the body in opposition to the support member 17, and the mounting port 1 2 1 penetrating the elongated hole 1 1 8 through the washer 1 2 0 is attached to the insert 1. By screwing the support member 1 19, the plurality of support members 1 17 are fixed to the side surface of the concrete receiving beam 4 so as to be vertically adjustable. On the horizontal half 1 117 h of the plurality of support members 1 17, the beam receiver 8 is mounted via anti-vibration rubber 122, as shown in FIG. 16. In FIG. 8, between the adjacent support members 117, a plurality of heavy beams 5 are suspended and supported by the aforementioned port nuts 113. An air gap D2 is formed between the ends of the plurality of large beams 5 and the side surface of the concrete beam 4, and between the lower surfaces of the large beams 5 and the floor slab S f. Is formed with the gap D1, whereby the plurality of large beams 5 do not directly contact the concrete receiving beam 4 and the floor slab Sf.

As shown in FIGS. 11 and 12, a plurality of joist beams 6 are laid in parallel with each other on the plurality of large beams 5. On these joists 6, a floor plate 7 made of a flooring plate or the like is laid, and this floor plate 7 is prevented from contacting with the concrete receiving beam 4. A floor structure Fr is composed of a plurality of large beams 5, left and right beam receivers 8, 8, a plurality of joists 6, and a floor plate 7.

As shown in FIG. 14, the support structure of the other ends of the plurality of large beams 5... To the vertical frame 2 is supported by the one end of the large beams 5. Since the structure is the same, the description is omitted.

The plurality of large beams 5 arranged on the floor slab S f with the gap D 1 are provided at both ends thereof with the gap D 2 to form the vibration isolating rubber 1 14 and the beam receiver 8. Are supported between the concrete beams 4 or between the concrete beams 4 and the vertical wall 2 through the concrete beams 4, so that the plurality of large beams 5 contact the floor slab S f. There is nothing.

As described above, in the living space Dw, both ends of the plurality of large beams 5… constituting the floor structure Fr are connected to the small beams B via the support members 117 and the beam receivers 8, 8. between the concrete beam 4 on s or between the beam 4 and the beam B b Each of the plurality of heavy beams 5 supported on the body wall 2 is prevented from contacting the floor slab S i, and the vibration and impact acting on the floor structure Fr is not propagated to the floor slab S f. .

The plurality of large beams 5 are supported on the floor structure Fr by supporting both ends thereof between the concrete receiving beams 4 arranged in parallel with each other or between the concrete receiving beams 4 and the vertical wall 2. The vibration noise caused by the load can be distributed to the concrete receiving beam 4 on the small beam B s or the vertical frame wall F h on the large beam B b via a plurality of large beams 5. Even when the area is widened across the small beams B s, the large beams 5 are supported by the concrete receiving beams 4, so that the vibration and noise applied to the floor can be reduced through the concrete receiving beams 4. And the sound insulation effect can be further enhanced. In addition, the load of the floor structure Fr should not act on the floor slab S f (the load acting on the floor slab S f from the concrete receiving beam 4 via the anti-vibration rubber 9 corresponds to the small beam B s), and does not propagate the sound to the floor slab S f), and does not have a sound insulation function. Therefore, this floor slab S f is larger than the slab thickness (20 to 27 cm) of the conventional floor slab. It is possible to make it as thin as possible (approximately 10 to 15 cm), which makes it possible to increase the indoor height of the living space Dw, and furthermore, to reduce the weight of the concrete frame F, In addition, the vibration control performance can be improved, and the cost of the building itself can be significantly reduced by reducing the amount of concrete and steel used.

Further, since the floor structure Fr can be supported below the floor plate 7 and on the concrete support 4 or the vertical frame wall 2, the floor structure Fr is located above the floor structure Fr. There is no member for supporting the body Fr, and the finishing wall material can be directly adhered to the vertical body wall 2, so that a wide indoor space can be secured. The beam receivers 8 are fixed to the upper surfaces of the ends of the plurality of large beams 5 and do not protrude below the lower surfaces of the large beams 5. The gap D1 between the floor slab Sf and the floor slab Sf can be set to the minimum necessary, and as a result, the occupation height of the underfloor space does not increase.

As described above, according to the fourth embodiment of the present invention, in a building having a regular beam concrete skeleton in which a floor slab is connected to the upper surface of a large beam and a small beam, The body and the floor slab are insulated, that is, their contact is avoided, and the transmission of vibration noise to the upper and lower floors, the right and left adjacent rooms can be reduced as much as possible, and the sound insulation effect can be improved. Is supported between concrete beams or between the concrete beams and the vertical frame walls to reduce the vibration noise applied to the floor structure with a large floor area. It can be dispersed and propagated through the concrete beam on the floor slab or the concrete frame via the vertical frame wall to further enhance the sound insulation effect, and furthermore, the floor structure can be stably supported. Further, the use of the floor support structure does not reduce the effective indoor space on the floor. Further, since the load of the floor structure does not act on the floor slab and the floor slab does not have the sound insulation function, it is necessary to make the floor slab as thin as possible than the slab thickness of the conventional floor slab. This makes it possible to increase the effective height of the living space, further reduce the weight of the concrete frame, improve seismic resistance and vibration control performance, and furthermore, By reducing the amount of steel used, the cost of the building itself can be significantly reduced.

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

In the fifth embodiment, the same components as those in the fourth embodiment are denoted by the same reference numerals.

The fifth embodiment is slightly different from the first embodiment in the structure for supporting the heavy beams 5 to the concrete receiving beams 4 (vertical body walls 2). The ends of the plurality of large beams 5 arranged in parallel on one plane are connected together by a beam receiver 8 extending perpendicular to them. The beam receiver 8 is formed of an equilateral angle steel having an angled cross section, and its horizontal half 8 h is provided on the upper surface of the end of the large beam 5 by means of a port nut 130 through vibration isolating rubber 13 1. And the vertical half 8 V extends downward across the end face of the plurality of heavy beams 5... Between the adjacent large beams 5, 5. It is fixed to the upper side of the concrete receiving beam 4 with the anchor ports 13 2 respectively. Therefore, the plurality of large beams 5 arranged on the floor slab S f with the air gap D 1 at their ends having the air gap D 2 and the vibration isolating rubber 13 1 and the beam receiver 8 are provided. Is supported by the concrete beam 4 via the slab, whereby the plurality of heavy beam beams 5 are brought into direct contact with the floor slab S f and the concrete beam 4. There is no.

Thus, the fifth embodiment has the same operation and effect as the fourth embodiment.

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

In the sixth embodiment, the same components as those in the fourth and fifth embodiments are denoted by the same reference numerals.

In the sixth embodiment, a gap s is formed at a predetermined width between the lower surface of the concrete beam 4 and the upper surface of the floor slab S f, and the load applied to the floor structure Fr is reduced by the concrete beam 4 ( In this case, the concrete beam 4 is struck together with the concrete frame F by the framework of a formwork (not shown). At the time of forming and forming, the styrofoam material 140 is interposed between the concrete receiving beam 4 and the floor slab S f in advance, and then the styrofoam 140 is removed by incineration or the like.

As described above, according to the sixth embodiment of the present invention, the concrete beam 4 and the floor slab Sf are in a non-contact state via the air gap s, and the vibration impact applied to the concrete beam 4 is small. The concrete beam F is dispersed and propagated from the concrete receiving beam 4 (vertical frame wall 2) to the concrete frame F without being propagated to the beam Bs. In addition, since the beam receiver can be supported on the concrete beam or the vertical frame wall, the beam can be supported on the concrete beam or the vertical wall regardless of the position of the large beam. It is possible to accurately and easily adjust the vertical position with respect to the concrete beam or the vertical body wall.

Although the first to sixth embodiments of the present invention have been described above, the present invention is not limited to those embodiments, and various embodiments are possible within the scope of the present invention.

For example, in the above embodiment, the case where the floor support structure in the building according to the present invention is applied to an apartment house has been described, but this can be applied to other concrete buildings. Further, as the floor plate of the floor structure, a flooring plate, a tatami floor, or other known materials can be used.
