When increasing the floor area to expand the area where OA equipment can be installed, if the entire floor surface is configured with a single floor panel, the weight of the floor panel will be extremely large, resulting in poor workability of the floor surface. The problem arises that it gets worse. In addition, when the entire floor surface is composed of a single floor panel, it is difficult to construct floor surfaces of various sizes and shapes. As a measure for solving such problems, it is conceivable to configure the floor surface with a plurality of floor panels. In this case, the floor surface is constructed by arranging adjacent to each other a plurality of floor panels having grooves for wiring wiring formed on the upper surface.

When a floor is configured with a plurality of floor panels, it is necessary to use a plurality of types of floor panels with different widths in order to improve the degree of freedom in designing the size and shape of the floor. When a plurality of floor panels selected from a plurality of types of floor panels are arranged adjacent to each other, the grooves formed on the upper surface of each floor panel communicate with each other at the abutting portion where the floor panels of different types are abutted. There is a risk that it will be in a state where it is not If the grooves of a plurality of floor panels are not in communication with each other, the degree of freedom in laying wiring is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to improve the degree of freedom in wiring when constructing a floor surface of a building with a plurality of floor panels.

A floor panel according to one aspect of the present invention is a floor panel used to construct a floor surface. The floor panel has a rectangular planar shape having a pair of first sides extending in a predetermined first direction and a pair of second sides extending in a second direction perpendicular to the first direction. The upper surface of the floor panel for forming the floor surface has a plurality of first grooves extending over the entire length in the first direction and opening upward, and at least one second groove that opens and intersects the first groove. The first grooves are arranged along each side edge of the pair of first sides and have a shape that opens in the direction in which the end surface of the floor panel in the second direction faces. include.

According to this floor panel, the upper surface of the floor panel for forming the floor surface has a plurality of first grooves extending over the entire length of the pair of first sides and a plurality of grooves extending over the entire length of the pair of second sides. At least one second groove is formed intersecting with the first groove. At this time, the plurality of first grooves includes first edge grooves arranged along each edge of the pair of first sides. Wiring to be connected to OA equipment can be routed using the first groove including the first marginal groove formed on the upper surface of the floor panel and the second groove intersecting with the first groove. .

Floors of various sizes and shapes can be easily constructed by constructing a floor surface using a plurality of types of floor panels with different set dimensions defined by the lengths of a pair of first sides and a pair of second sides. , the degree of freedom in designing the size and shape of the floor surface can be improved. In this case, the case where the floor surface is configured using a plurality of types of floor panels specified by the floor panel having the first groove including the first marginal groove and the second groove formed on the upper surface is referred to as a floor panel. Three patterns with different parts to be matched with each other are considered.

In the first butting pattern, it is assumed that a plurality of floor panels are arranged such that the first sides of the floor panels are butted against each other. In this case, a communicating groove is formed by combining the first marginal grooves in the abutting portion of the first sides of the floor panel, and a second groove intersecting with the first marginal groove is formed on the upper surface of each floor panel. It extends over the entire length of the second side. As a result, the communication groove formed by combining the first marginal grooves formed in the abutting portion of the first sides of the floor panel and the second groove intersecting the first marginal groove are used to improve the floor surface. Since the wiring can be arranged freely in the planar direction, the degree of freedom in wiring arrangement can be improved.

In this case, the first marginal groove of one floor panel and the first marginal groove of the other floor panel are orthogonal to each other and communicate with each other to form a communication groove. A second groove that intersects the edge groove extends the full length of the second side. As a result, the first edge grooves of the floor panels intersect perpendicularly and communicate with each other, and the second grooves intersecting the first edge grooves are used to achieve the floor surface direction. Since the wiring can be arranged freely, the degree of freedom of wiring arrangement can be improved.

In the floor panel described above, the second grooves are arranged along each side edge of the pair of second sides and have a shape that opens in the direction in which the end face of the floor panel in the first direction faces. The configuration may include marginal grooves.

In this aspect, the second groove formed in the top surface of the floor panel includes a pair of second marginal grooves arranged along respective margins of the pair of second sides. It is assumed that a floor surface is constructed using a plurality of types of floor panels specified by a floor panel having a first groove including a first marginal groove and a second groove including a second marginal groove formed on the upper surface. do.

The floor panel unit 2 includes a plurality of floor panels 4, a connecting member 5 for connecting the plurality of floor panels 4, a plurality of fixing members 6 arranged corresponding to each floor panel 4, and floor beams 8. and a plurality of vibration-isolating materials 7 provided in the

A plurality of floor panels 4 straddle between two floor beams 8 adjacent to each other, and are supported by the floor beams 8 from below while being arranged adjacent to each other in the X-axis direction and the Y-axis direction. be done. The floor panel 4 is composed of, for example, a floor slab, an ALC (autoclaved lightweight aerated concrete), a hollow extruded cement board, a precast concrete board, or the like. A floor panel 4 made of a hollow extruded cement board has a hollow portion, and the hollow portion is filled with a sand-like inorganic material.

The floor panel 4 is a board having a rectangular planar shape having a pair of first sides 41 extending in a predetermined first direction D1 and a pair of second sides 42 extending in a second direction D2 orthogonal to the first direction D1. It is a shaped member. In the example of FIG. 1, the floor panel 4 is bridged between the two floor beams 8 so that the pair of first sides 41 extend in the X-axis direction and the pair of second sides 42 extend in the Y-axis direction. . In this state, the plurality of floor panels 4 are provided on each floor joist 8 while being adjacent to each other in the X-axis direction along the horizontal plane.

FIG. 1 shows an example in which the vibration isolator 7 is arranged on the upper flange 81 of the pair of flanges 81 of the floor beam 8 at positions corresponding to the four corners of each floor panel 4 in plan view. there is

The upper surface 43 of each of the plurality of floor panels 4 constitutes the floor surface of the building. The upper surface 43 of each floor panel 4 has a plurality of first grooves 44 extending over the entire length of the pair of first sides 41 extending in the first direction D1 and opening upward, and a pair of second grooves 44 extending in the second direction D2. and at least one second groove 45 extending over the entire length of the side 42, opening upward, and intersecting the first groove 44 is formed. Using the first groove 44 and the second groove 45 of each floor panel 4, wiring to be connected to OA equipment can be routed. A plurality of floor panels 4 having first grooves 44 and second grooves 45 formed in the upper surface 43 are arranged adjacent to each other to form a floor surface. By configuring the floor surface with a plurality of floor panels 4 in this way, the weight of each floor panel 4 can be reduced compared to the case where the entire floor surface is configured with a single floor panel, so wiring can be arranged. It is possible to improve the workability of the floor surface. In addition, by constructing a floor surface with a plurality of floor panels 4, it is possible to easily construct floor surfaces of various sizes and shapes, thereby improving the degree of freedom in designing floor surface sizes and shapes. becomes possible.

A plurality of first grooves 44 formed in the upper surface 43 of the floor panel 4 are arranged along each edge of the pair of first sides 41, open upward, and extend along the end surface of the floor panel 4 in the second direction D2. It includes a pair of first marginal grooves 441 having a shape that opens in the facing end face direction. Further, when the pair of second sides 42 is longer than the pair of first sides 41, the plurality of first grooves 44 are arranged at predetermined equal intervals between the pair of first edge grooves 441 in the second direction D2. and further includes at least one first intermediate groove 442 that opens upward.

The second grooves 45 formed in the upper surface 43 of the floor panel 4 are arranged along each edge of the pair of second sides 42, open upward, and face the end surface of the floor panel 4 in the first direction D1. It includes a pair of second marginal grooves 451 having a shape that opens in a direction.

As described above, the plurality of floor panels 4 are arranged such that the pair of first sides 41 are arranged on the flanges 81 of the respective floor beams 8 and one sides of the pair of second sides 42 are butted against each other. They are arranged adjacent to each other, and in this state are supported by the floor beams 8 from below. In a state in which a plurality of floor panels 4 are arranged adjacent to each other on each floor joist 8 in this manner, the pair of first marginal grooves 441 of each floor panel 4 communicate with the first marginal communication grooves 4411. A first intermediate communication groove 4421 is formed in which the first intermediate grooves 442 communicate with each other, and the abutting portion where the second sides 42 of the floor panels 4 are abutted is formed by the combination of the second edge grooves 451. Abutment communication groove 4511 is formed.

In a state in which a plurality of floor panels 4 are arranged adjacent to each other on each floor joist 8, the connecting member 5 is connected to at least the first marginal communication groove 4411 of the first marginal communication groove 4411 and the first intermediate communication groove 4421. The floor panels 4 are configured to be connectable by being inserted from above into the respective communication grooves of the floor panels 4 and fixed to each of the plurality of floor panels 4 by fasteners such as fastening bolts. The connecting member 5 extends in the longitudinal direction of at least each of the first marginal communication groove 4411 and the first intermediate communication groove 4421 and forms a space that opens upward. It is inserted into the communicating groove.

As a result, the first marginal communication groove 4411 in which the pair of first marginal grooves 441 of each floor panel 4 communicate with each other and the first intermediate communication groove 4421 in which the first intermediate grooves 442 communicate with each other are formed. , the first marginal communication groove 4411 and the first intermediate communication groove 4421, at least the connecting members 5 inserted into the communication grooves of the first marginal communication groove 4411 can integrate the plurality of floor panels 4. . By integrating the plurality of floor panels 4, it is possible to maintain the state of communication between the first grooves 44 of each floor panel 4, and also maintain the positional relationship between the second grooves 45 of the adjacent floor panels 4. be done. As a result, the wiring can be laid freely in the planar direction of the floor surface of the building by using the first grooves 44 and the second grooves 45 formed on the upper surface 43 of the plurality of floor panels 4. The degree of freedom of the rope can be improved.

Further, as described above, in the floor structure 1 to which the floor panel unit 2 is applied, the vibration isolator 7 is provided between the floor beams 8 and the plurality of floor panels 4 . Therefore, the vibration isolator 7 is elastically deformed according to the vibration of each floor panel 4 , thereby lowering the resonance frequency of each floor panel 4 . Vibration propagation to 8 can be suppressed. As a result, it is possible to improve the blocking performance of the floor impact sound (hereafter referred to as "heavy floor impact sound") having a frequency that serves as an index for the floor structure 1. FIG.

Here, in order to lower the resonance frequency of the floor panel 4 and efficiently improve the performance of blocking heavy floor impact noise, it is better to soften the vibration isolator 7 . However, if the weight of the floor panel 4 and the load applied to the floor panel 4 compress the vibration isolator 7 beyond the allowable value, it may not be possible to improve the ability to block heavy floor impact noise. Therefore, it is necessary to set the softness of the vibration-isolating material 7 based on the load received by the vibration-isolating material 7 and the allowable load of the vibration-isolating material 7 indicating the allowable value. When the vibration-isolating material 7 is softened within a range in which the load received by the vibration-isolating material 7 does not exceed the allowable load, if the softness exceeds a certain level, the plurality of floor panels 4 will break when an impact is applied to each floor panel 4. A phenomenon occurs in which each of 4 vibrates independently with rotation and twist. When a plurality of floor panels 4 vibrate individually, vibration in a predetermined frequency band (octave band center frequency 63 Hz), which is an index of the ability of the floor structure 1 to block heavy floor impact sound, becomes large.

Therefore, the plurality of floor panels 4 are integrated by connecting the connecting members 5 inserted into at least the communicating grooves of the first edge communicating groove 4411 and the first intermediate communicating groove 4421 . Integrating the plurality of floor panels 4 by the connecting members 5 in this way can suppress the plurality of floor panels 4 from vibrating due to individual rotation and twisting.

A communicating hole 521 is formed.

The bending strength of the connecting member 5 can be increased by forming the connecting member 5 having a pair of side plate portions 52 rising from both side ends of the mounting plate portion 51 . In addition, the bending strength of the connecting member 5 can be further increased by using the connecting member 5 further including the bent portions 53 protruding inward from the upper ends of the pair of side plate portions 52 . As a result, deformation of the connecting member 5 can be suppressed when the plurality of floor panels 4 are connected and integrated, so that the effect of connecting the plurality of floor panels 4 by the connecting member 5 can be enhanced.

It has a height dimension for restricting upward projection from the first edge groove 441 and the first intermediate groove 442 that constitute the communication groove. A stepped portion 46 is formed at the upper edge of the first groove 44 and the second groove 45 of the floor panel 4 . A lid member 9 is placed on the stepped portion 46 of the floor panel 4 to close the first groove 44 and the second groove 45 from above. The lid member 9 is placed on the stepped portion 46 so as to be flush with the upper surface 43 of the floor panel 4 . The lid member 9 placed on the stepped portion 46 is supported from below by the bent portion 53 of the connecting member 5 . A floor finishing material such as a tile carpet is laid on the upper surface 43 of the floor panel 4 and the lid member 9 .

Further, the pair of side plate portions 52 of the connecting member 5 are formed with communication holes 521 communicating with the second groove 45 when the mounting plate portion 51 is mounted on the bottom surface of the first groove 44 . . By inserting the connecting member 5 into at least the first edge communication groove 4411 of the first edge communication groove 4411 and the first intermediate communication groove 4421 formed by communicating the first grooves 44 of each floor panel 4 A plurality of communication holes 521 communicating with the second grooves 45 of each floor panel 4 are formed in the pair of side plate portions 52 when the mounting plate portion 51 is placed on the bottom surface of the first groove 44 . Each communication hole 521 is formed at an appropriate position that can communicate with the second groove 45 of each floor panel 4 in the longitudinal direction of the pair of side plate portions 52 . By forming the communication holes 521 in the pair of side plate portions 52 of the connecting member 5 in this way, the state of communication between the second groove 45 and the first groove 44 in the upper surface 43 of each floor panel 4 is changed to that of the pair of side plate portions 52 . can be suppressed from being blocked by As a result, in a state in which the connecting member 5 is inserted into at least the first edge communication groove 4411 of the first edge communication groove 4411 and the first intermediate communication groove 4421, wiring using the first groove 44 and the second groove 45 is performed.
