Abstract

(57) [Summary] [Purpose] In a structure in which floor members for access floors are connected to each other using a connecting tool, the connecting tool is firmly held at the same time as the connection so as not to slip out of the floor member. [Structure] A floor member A having leg plates 2a and 2b at four corners of a top plate 1 and notch openings 3 provided at corners of the top plate.
Of the board body portion having the groove portions 7 which are arranged vertically and horizontally and which fit the exposed leg plate portions 2a at the notched openings of the four floor members which are vertically and horizontally adjacent to each other and connect the floor members to each other, and on the periphery of the board body portion. Hook part that is projected and elastically deforms by hitting the cutout opening edge of each floor member when fitted to the leg plate part of the board part, and restored after passing through the cutout opening to engage with the back surface of the top plate part The floor members are connected to each other using a connecting tool B composed of 5 and 5. [Effect] When the groove portion 7 of the board portion is fitted into the leg plate portion 2a of the floor member, the hook portion 7 enters the lower side of the upper surface plate portion 1, so that the connecting tool does not come out of the floor member.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a floor structure in which a space under which a communication cable, a power line, and the like can be wired is formed, that is, a connection structure of floor members used for a so-called access floor.

[0002]

[Prior art]

 Conventionally, as a connecting structure for the floor member for the access floor, arc-shaped grooves are provided at each corner of the upper surface of a floor panel having a rectangular flat plate portion, and the floor panel is laid on the floor slab and adjacent to each other. A structure in which the groove portions of the floor panels to be connected are connected to each other to form a circumferential locking groove, and a ring-shaped connecting tool is fitted in the locking groove to connect the adjacent floor panels to each other, is a practically open 2-87851. No.

[0003]

[Problems to be solved by the device]

 In the floor panel connection structure with the above configuration, the ring-shaped connection tool is simply fitted into the arc groove on the floor panel side.Therefore, due to the looseness of the floor panel due to the unevenness of the floor slab, There is a problem that it easily floats up and comes off.

[0004]

[The purpose of the device]

 An object of the present invention is to provide a floor member connecting structure capable of securely holding a connecting member fitted to a floor member so as not to come off later.

[0005]

[Means for Solving the Problems]

 The present invention has a rectangular top plate having leg plates at least at four corners, and notched openings are provided at the corners of the top plate to expose the corners of the leg and the floor members are vertically and horizontally arranged. Of the four floor members that are vertically and horizontally adjacent to each other, the panel body portion is supported by the exposed portions from the notch openings of the leg plate portions, and regulates the mutual position of the floor members. A hook designed to be elastically deformed by hitting the cutout opening edge of each floor member when the body part is placed on the leg plate part, and restored after passing through the cutout opening so that it can be engaged with the back surface of the top plate part. The gist is a structure in which floor members are connected to each other by a connecting tool including a section.

[0006]

[Action]

 According to the above configuration, when the connecting tool is attached to the floor member, the hook portion thereof engages with the back surface of the floor member, so that the connecting member does not come off from the floor member.

[0007]

【Example】

 1 to 4 show an embodiment of the present invention. In the figure, A is a floor member for an access floor formed by bending a metal plate into a box shape. Reference numeral 1 denotes a rectangular upper surface plate portion forming a floor member, 2a and 2b are leg plate portions bent from the peripheral edge of the upper surface plate portion, and cutout openings 3 are provided at corners of the upper surface plate portion 1, The end portions of the leg plate portions 2a and 2b are exposed.

Reference numeral B is a connecting member formed of synthetic resin. This connector is formed by integrally forming V-shaped hook portions 5 projecting downwardly from the four corner portions of the board body portion 4 and then bending upward, and at the board body portion 4, the edges thereof are formed. The groove portion 6 which is parallel to the side-symmetrical axis line and vertically penetrates, and the groove portion 7 which is parallel to the symmetrical axis line which is orthogonal to the symmetrical axis line and which extends from the back surface of the board portion to approximately half the thickness of the board body, and is orthogonal to the groove portion 7. It is provided with shallow V-shaped grooves 8 and 9 provided on both the front and back surfaces of the board portion that come in contact with both axes of symmetry and a circular through hole 10 provided at the intersection of both axes of symmetry.

FIG. 1A shows a state in which four floor members A vertically and horizontally adjacent to each other are connected by a connecting tool B.

The connecting procedure is as follows: On the floor slab, four leg members that are vertically and horizontally arranged at a required interval are exposed from the cutout openings 3 at the corners of the floor member A. The board portion 4 of the connecting tool B is placed on the upper surfaces of 2a and 2b, and the groove portion 7 on the back surface thereof is positioned so as to be aligned with the leg plate portion 2a of each floor member A. In this state, the hook portion 5 is applied to the edge of the cutout opening 3, but when the board portion 4 is pressed to fit the groove portion 7 into the leg plate portion 2a, the hook portion 5 is inserted into the cutout opening 3 by the cutout portion 3. When it is tilted toward the center of the portion, it is released through the notch opening 3 at the same time, so that it returns to its original angular position by its repulsive elasticity and engages with the back surface of the top plate portion 1. Further, at that time, the leg plate portion 2b is sandwiched by the through groove portion 6 provided in the board portion 4, and the position is regulated.

By assembling the connecting tool B to the floor member A as described above, the four vertically and horizontally adjacent floor members A are connected, and the connecting tool B is firmly held so as not to come out of the floor member A. To be done.

Further, since the board portion 4 forming the connecting tool can be bent at the portions of the V-shaped grooves 8 and 9 provided in the portion corresponding to the orthogonal axis of symmetry, the unevenness of the floor slab can be prevented. A good absorption effect can be obtained against rattling of the floor material due to.

Further, in this embodiment, since the groove portion 7 provided on the back surface of the board body portion 4 is adapted to be fitted to the exposed portion of the leg plate portions 2a and 2b, the board body portion 4 is attached to the leg plate portion 2a. , 2b are more securely connected to the floor members than when they are placed on the exposed portions of the floor members. A flexible surface material such as carpet is provided on the surfaces of all the floor members connected by the above-mentioned connecting tool, and the access floor is completed.

[0014]

[Effect of device]

 As described above, according to the present invention, the floor members can be connected to each other only by placing the connecting members between the floor members adjacent to each other vertically and horizontally and pressing the connecting members. It can be held firmly so as not to come off from the member.
