As in the above-mentioned conventional flooring structure, the flooring structure is constructed by arranging a plurality of flooring members each having a floor base material such as a floor base body, and a support member provided below the floor base material to support the floor base material. . After installing the floor structure in this way, a worker walks on the floor structure and places a flooring material such as flooring on the floor structure. In the work of arranging such floor finishing materials, if the position of the flooring members is likely to shift, the work efficiency will be reduced. Further, for example, it may be necessary to remove some floor members from the floor structure. In this work of removing the floor member, if the floor member is difficult to remove, the work efficiency will be reduced. As described above, it is desired to improve the workability of placing floor finishing materials, removing flooring members, and the like.

The present invention has been made in view of these circumstances, and its purpose is to provide a bed structure that can provide good workability.

A flooring structure that solves the above problem is a flooring structure that includes a plurality of flooring members arranged adjacent to each other on a base, the flooring members including a floor base material and a floor base material below the floor base material. a support member provided on a side to support the floor base material; the floor structure further includes a connecting member connecting at least two adjacent floor members; a connection base that is disposed between the matching support members to separate the floor members in plan view; a connection frame provided on the connection base so as to surround each of the support members; and a connection base and the connection. and an insertion part formed by a frame part and into which the supporting member can be inserted and removed in the vertical direction.

According to this configuration, the support member inserted into the insertion portion of the connection member is surrounded by the connection frame portion of the connection member, so that it is possible to suppress relative displacement of support members of adjacent floor members. . Thereby, it is possible to suppress relative positional displacement of adjacent flooring members. For this reason, for example, when placing the floor finishing material on the floor placing structure, it becomes easier for the worker to walk on the placing floor structure, and the workability of placing the floor finishing material becomes good. Furthermore, for example, if it becomes necessary to remove some of the bed members from the bed structure, the support member can be easily removed from the insertion part of the connection member by lifting the bed member. Good workability can also be obtained in the work of removing the flooring member.

In the above bed structure, it is preferable that the insertion portion opens downward, and the support member is in contact with a base on which the bed member is placed.
According to this configuration, since the connecting member does not affect the height of the floor base material, it is possible to suppress the thickness of the floor structure, for example.

In the above-mentioned bed structure, it is preferable that the support member is made of a rubber-based material.
According to this configuration, for example, transmission of vibration from the floor base material to the base can be suppressed.

In the above-mentioned bed structure, it is preferable that the connection member is made of a rubber-based material or a fiber-based material.
According to this configuration, a buffering function can be provided to the connecting member. Thereby, for example, it is possible to suppress the generation of abnormal noise caused by contact between the connecting member and the supporting member.

In the above-mentioned bed structure, it is preferable that the connection frame portion has a narrow portion narrower than the width of the connection base.
According to this configuration, since the connection frame part is more easily deformed than the connection base part, the support member can be easily inserted into and removed from the insertion part by utilizing the deformation of the connection frame part.

In the above bed structure, it is preferable that the connection member has an endless annular structure formed by the connection base and the connection frame, and the inner side of the endless annular structure is configured as the insertion part.

According to this configuration, by suppressing excessive deformation of the insertion portion, relative displacement of at least two support members connected to the connection member can be further suppressed.
The above-mentioned floor placement structure includes three of the floor placement members adjacent to each other, the shape of the floor base material of the three of the floor placement members is a rectangular shape in plan view , and the support member of the three of the said floor placement members is corner support members attached to four corners of the base material, and intermediate support members attached between a pair of adjacent corners of the floor base material, and at least three as the connection members. A connecting member capable of connecting the flooring members is provided, and each corner support member of two of the three flooring members and an intermediate support member of one flooring member are connected by the one connecting member. It is preferable to have a structure that is similar to the above.

According to this configuration, the first gap is formed between the pair of floor members in which the corner support member is connected to the connection member and the floor member in which the intermediate support member is connected to the connection member. Further, a second gap is formed between the pair of floor members to which the corner support member is connected to the connection member. The first gap and the second gap extend to intersect in a T-shape when viewed from above. By complicating the position of the gap in this way, the vibration transmission path between adjacent bed members becomes complicated, and the vibration of the bed structure becomes more likely to be damped.

According to the present invention, good workability can be obtained.

Flooring members 11 that are adjacent to each other in the X-axis direction and the Y-axis direction are spaced apart from each other in a plan view. In the floor structure 61 configured in this manner, there is no portion where adjacent floor members 11 overlap.

In the floor structure 61, the gap between the adjacent floor members 11 is composed of a first gap S1 extending along the X-axis direction and a second gap S2 extending along the Y-axis direction. There is. The first gap S1 is a gap between adjacent flooring members 11 in the Y-axis direction. The second gap S2 is a gap between the floor members 11 that are adjacent to each other in the X-axis direction.

The first gaps S1, S1 located on both sides of the connecting member 51 in the X-axis direction are located on the same straight line along the X-axis direction. On the other hand, the second gap S2 is not located on both sides of the connection member 51 in the Y-axis direction, but is located on one side of the connection member 51 in the Y-axis direction. In other words, in the floor structure 61 of this embodiment, each of the short sides (the second side 21b and the fourth side 21d of the floor base material 21) of the floor members 11 adjacent to each other in the Y-axis direction are aligned along the Y-axis direction. are not located on the same straight line.

In the floor structure 61, the connection member 51 is in contact with the support member 31. The connecting member 51 disposed on the outer periphery of the floor structure 61 may be brought into contact with a wall surface of a wall installed around the floor structure 61.

Next, a method of constructing the floor structure 61 will be explained.
As shown in FIGS. 5 and 6, the floor placement structure 61 is constructed by placing the connection member 51 on the base B, and inserting the support member 31 of the floor placement member 11 into the insertion portion 54 of the connection member 51 from above. It can be formed by repeating the work of sequentially arranging the members 11. The connection base portion 52 of the connection member 51 serves as a spacer for spacing the supporting members 31 of adjacent flooring members 11, so that adjacent flooring members 11 can be arranged with a predetermined spacing between them. Note that the portion of the sound absorbing member 41 that is pressed by the connecting member 51 is compressed and deformed.

A floor finishing material (not shown) is arranged on the upper surface side of the floor structure 61 arranged in this way. Examples of floor finishing materials include flooring, cork boards, tiles, tatami mats, carpets, resin sheet materials, and rubber sheet materials.

Next, the main functions of the floor structure 61 will be explained.
In the floor structure 61 , adjacent floor members 11 are connected by a connecting member 51 . The connection member 51 has a connection base 52 , a connection frame 53 , and an insertion portion 54 . According to this configuration, the support member 31 inserted into the insertion portion 54 of the connection member 51 is surrounded by the connection frame portion 53 of the connection member 51, so that the support members 31 of the adjacent floor members 11 are relative to each other. Misalignment can be suppressed. Thereby, it is possible to suppress relative displacement of the floor members 11 that are adjacent to each other. Therefore, for example, when placing the floor finishing material on the placing floor structure 61, it becomes easier for the worker to walk on the placing floor structure 61, and the workability of placing the floor finishing material becomes good. Further, for example, when it becomes necessary to remove some of the floor members 11 from the floor structure 61, the supporting member 31 can be easily removed from the insertion portion 54 of the connecting member 51 by lifting the floor member 11. Therefore, good workability can be obtained in the work of removing the floor placement member 11.

Next, the functions and effects of this embodiment will be explained.
(1) The floor member 11 includes a floor base material 21 and a support member 31 that is provided below the floor base material 21 and supports the floor base material 21. The floor structure 61 further includes a connecting member 51 that connects the floor members 11 adjacent to each other. The connection member 51 has a connection base 52 that is disposed between the support members 31 adjacent to each other and separates the floor member 11 in a plan view. The connection member 51 has a connection frame 53 connected to the connection base 52 so as to surround each of the support members 31 adjacent to each other. The connection member 51 is formed by a connection base 52 and a connection frame 53, and has an insertion portion 54 into which the support member 31 can be inserted and removed in the vertical direction.

According to this configuration, good workability can be obtained due to the above-mentioned effects.
(2) The insertion portion 54 of the connection member 51 opens downward, and the support member 31 is in contact with the base B on which the floor member 11 is placed. In this case, since the connecting member 51 does not affect the height of the floor base material 21, the thickness of the floor structure 61 can be suppressed, for example. Further, by configuring the vibration transmission path between the floor base material 21 and the base B with the support member 31, it is also possible to fully exhibit the buffering performance of the support member 31, for example.

(3) It is preferable that the support member 31 is made of a rubber-based material. In this case, for example, transmission of vibrations from the floor base material 21 to the base B can be suppressed.
(4) The connecting member 51 is preferably made of a rubber-based material or a fiber-based material. In this case, the connecting member 51 can be provided with a buffering function. Thereby, for example, it is possible to suppress the occurrence of abnormal noise caused by contact between the connecting member 51 and the supporting member 31. Further, for example, when the connection member 51 and the wall surface around the floor placement structure 61 are used in contact with each other, it is possible to suppress the generation of abnormal noise due to the contact.

(5) In the connecting member 51, the connecting frame portion 53 has a narrow portion 53a that is narrower than the width of the connecting base portion 52. In this case, since the connection frame portion 53 is more easily deformed than the connection base portion 52, the support member 31 can be easily inserted into and removed from the insertion portion 54 by utilizing the deformation of the connection frame portion 53. Therefore, better workability can be obtained.

(6) The connection member 51 has an endless annular structure formed by the connection base 52 and the connection frame 53, and the inner side of the endless annular structure is configured as the insertion part 54. In this case, by suppressing excessive deformation of the insertion portion 54, relative positional displacement of each support member 31 can be further suppressed. That is, this is particularly advantageous when it is desired to give priority to suppressing the relative displacement of each floor member 11 connected to the connecting member 51.

(7) The floor structure 61 includes three floor members 11 adjacent to each other. The shape of the three floor base materials 21 is rectangular in plan view. The support members 31 of the three floor members 11 include corner support members 32 attached to four corners of the floor base material 21 and intermediate support members attached between a pair of adjacent corners of the floor base material 21. 33 respectively. The floor structure 61 includes a connecting member 51 to which at least three floor members 11 can be connected. The floor structure 61 has a structure in which each corner support member 32 of two of the three floor members 11 and the intermediate support member 33 of one floor member 11 are connected by one connection member 51. have.

In this case, a first gap S1 is formed between the pair of floor members 11 to which the corner support members 32 are connected to the connection members 51 and the floor members 11 to which the intermediate support members 33 are connected to the connection members 51. be done. Further, a second gap S2 is formed between the pair of floor members 11 to which the corner support member 32 is connected to the connection member 51. The first gap S1 and the second gap S2 extend so as to intersect in a T-shape when viewed from above. By complicating the position of the gap in this way, the transmission path of vibrations in the adjacent floor members 11 becomes complicated, and the vibrations of the floor structure 61 are more likely to be damped.

In addition, in a structure in which not only the corner support members 32 but also the intermediate support members 33 are connected to the connection members 51, it is possible to increase the number of connection members 51 used per predetermined floor area. The buffering function can be made more effective.
