Description

[Technical field]

[0001] The present invention relates to a floor panel fixing bracket used for fixing floor panels onto a folded plate roof, etc. [Background technology]

[0002] For example, in order to install scaffolding for outdoor units of air conditioning equipment installed on the roof or for walkways for maintenance of solar panels, a technique is known in which a floor panel material is placed on top of an H-shaped steel beam and the flange of the H-shaped steel and the floor panel material are sandwiched and fixed between a lower bracket and an upper bracket (see, for example, Patent Document 1).

[0003] Also known is a technology that reduces weight by using a channel material that is open at the top instead of H-shaped steel, and fixing the channel material and floor plate material between lower and upper metal fittings using bolts that are erected from the internal space of the channel material. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-144553 A Summary of the Invention [Problem to be solved by the invention]

[0005] When the floor plate is fixed by a bolt extending from the internal space of the channel, the position of the bolt can be moved in the longitudinal direction of the channel, but cannot be moved in a direction perpendicular to the longitudinal direction, making it difficult to set the position of the floor plate in the direction perpendicular to the longitudinal direction with a high degree of freedom.

[0006] In other words, the floorboard could not be fixed unless the long hole in the floorboard was aligned directly above the folded-back portion of the channel material, which required the time-consuming task of shifting the floorboard to adjust its position.

[0007] The present invention has been made in consideration of the above points, and has an object to increase the degree of freedom in positioning floorboard materials. [Means for solving the problem]

[0008] In order to achieve the above objectives, The present invention relates to A floorboard fixing fitting for fixing a floorboard to a channel material having a bottom wall, a pair of side walls rising from both sides of the bottom wall, and folded back portions folded inward from upper edges of the side walls, the floorboard being fixed to the channel material with long holes in the longitudinal direction of the channel material that are successively provided at predetermined intervals in a direction perpendicular to the longitudinal direction, A clamp that presses the floorboard material from the top side toward the bottom side; A receiving metal fitting that is engaged with the channel material; a screw member and a nut for tightening the clamping metal fitting and the receiving metal fitting in a direction in which they approach each other; Equipped with The above clamps are a pair of abutment portions that abut on an upper surface of the floor plate material on both sides of the slot of the floor plate material; a screw hole through which the screw member is inserted, and a recess between the pair of abutting portions that fits into the slot in the floor panel material; The above brackets are a locking portion having an outer dimension in a first direction shorter than a gap distance between the end edges of the folded portion of the channel material and an outer dimension in a second direction intersecting the first direction longer than the gap distance, the locking portion being locked to the folded portion of the channel material when the first direction is oriented in the longitudinal direction of the channel material; a nut holding portion that holds the nut slidably in the second direction; a connection portion having an outer dimension capable of rotating within the gap distance and connecting the locking portion and the nut holding portion; The present invention is characterized by having the following.

[0009] With this, since the nut is provided so as to be slidable in the second direction, the floor plate can be fixed to the channel even if, for example, the slot in the floor plate is not directly above the channel. Effect of the Invention

[0010] The present invention allows greater freedom in positioning of floorboard materials. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, as an embodiment of the present invention, an example in which floor panel materials are fixed onto a folded plate roof will be described in detail with reference to the drawings.

[0013] Scaffolding or the like installed on a roof is configured by fixing floor board material 101 onto channel material 211 with floor board fixing brackets 300 as shown in Fig. 1. The channel material 211 is fixed to a seam portion 232 of a folded plate roof 231 with a gripping bracket 221, a bolt 222, and a nut 223 as shown in Fig. 2.

[0014] In the floor plate material 101, slots 101a are provided in the longitudinal direction of the channel material 211 (the direction of arrow A in FIG. 1) and are successively provided at predetermined intervals in a direction perpendicular to the longitudinal direction (the direction of arrow B in FIG. 1).

[0015] The channel member 211 has a bottom wall 211a, a pair of side walls 211b rising from both sides of the bottom wall 211a, and folded-back portions 211c folded inwardly from the upper edges of the side walls 211b.

[0016] The floorboard fixing bracket 300 comprises a clamping bracket 310 and a receiving bracket 320, which sandwich the floorboard material 101 and the folded portion 211c of the channel material 211 between them, and is configured to fix the floorboard material 101 by tightening with a screw member 330 and a nut 340.

[0017] As shown in Figs. 2 and 3, the clamping metal fitting 310 has a pair of abutting parts 311 that abut against the upper surface of the floorboard material 101 on both sides of the long hole 101a of the floorboard material 101, and a recessed part 312 that fits into the long hole 101a of the floorboard material 101 between them. The abutting parts 311 are formed with holes 311a and notches 311b that avoid the anti-slip protrusions (embossments) provided on the upper surface side of the floorboard material 101, so that the floorboard material 101 can be held down more reliably. The recessed part 312 is formed with a screw hole 312a, through which a screw member 330 is inserted and which is prevented from falling off by a retaining washer 350. In addition, a hanging claw part 311c is provided on the edge of the abutting parts 311 on the opposite side to the recessed part 312, so that the floorboard material 101 can be fixed at the side in the width direction, i.e., near the end of the long hole 101a, as described later.

[0018] As shown in FIG. 4, the receiving metal fitting 320 has a locking portion 320a, a nut holding portion 320b, and a connecting portion 320c that connects the locking portion 320a and the nut holding portion 320b.

[0019] The locking portion 320a is set such that an outer dimension in a first direction (arrow C direction in FIG. 4) is shorter than the gap distance between the edges of the folded-back portion 211c of the channel material 211, and an outer dimension in a second direction (arrow D direction in FIG. 4) intersecting the first direction is longer than the gap distance. This allows the locking portion 320a to be inserted between the folded-back portions 211c of the channel material 211 when the D direction is oriented in the longitudinal direction of the channel material 211, and allows the locking portion 320a to be locked to the folded-back portions 211c of the channel material 211 when the C direction is oriented in the longitudinal direction of the channel material 211.

[0020] The nut holding portion 320b holds the nut 340 so as to be slidable in the D direction. More specifically, as shown in Figs. 4 and 5, the nut holding portion 320b has an upper wall portion 321 that covers the upper side and both sides of the nut 340, and a pair of side wall portions 322. The dimension between the opposing inner surfaces of the side wall portions 322 is set to a dimension that allows the two-face width of the nut 340 to be loosely fitted and prevents the nut 340 from rotating. In addition, the upper wall portion 321 is formed with an elongated hole 321a through which a screw member 330 that screws into the nut 340 is inserted and which can move with the sliding of the nut 340. In addition, a step portion 322a that supports the nut 340 so as to be slidable along the lower surface of the upper wall portion 321 is provided on the inner surface of the side wall portion 322.

[0021] Further, below the nut holding portion 320b, a recess 322b is formed into which the upper edge of the side wall 211b of the channel material 211 fits when the locking portion 320a is in a position separated from the folded-back portion 211c of the channel material 211, that is, when the receiving fitting 320 is deeply inserted between the folded-back portions 211c. This makes it possible to prevent the receiving fitting 320 from falling over or rotating when the locking portion 320a of the receiving fitting 320 is in a temporary placement state where it is inserted between the folded-back portions 211c.

[0022] The connecting portion 320c has an outer dimension that allows it to rotate within the gap distance between the edges of the folded-back portion 211c of the channel material 211, and connects the locking portion 320a and the nut holding portion 320b, so that the locking portion 320a and the connecting portion 320c form a substantially T-shaped shape, and the nut holding portion 320b and the connecting portion 320c form a substantially inverted T-shaped shape. More specifically, for example, the cross-sectional shape on a plane perpendicular to the axial direction of the screw member 330 includes portions corresponding to the vertices of a rectangle, and one length of the diagonal line of the rectangle is set to be shorter than the gap distance between the edges of the folded-back portion 211c of the channel material 211, and the other length of the diagonal line of the rectangle is set to be longer than the gap distance of the channel material 211. This prevents the locking portion 320a of the receiving bracket 320 from rotating beyond an angle of approximately 90 degrees after it is inserted between the folded-back portion 211c of the channel material 211, and prevents it from rotating when the screw member 330 is tightened.

[0023] As described above, floor plate 101 can be fixed by fitting recess 312 of clamp 310 into long hole 101a of floor plate 101, so that a plurality of floor plates 101 can be easily installed side by side with no gaps.

[0024] Furthermore, since the nut 340 is arranged to be slidable in a direction perpendicular to the longitudinal direction of the channel material 211, the floor panel material 101 can be fixed even if the long hole 101a of the floor panel material 101 is not directly above the floor panel material fixing bracket 300, i.e., the channel material 211.

[0025] Furthermore, by providing the claw portion 311c on the edge of the abutting portion 311 of the pressing bracket 310 opposite the recess 312 as described above, the floorboard material 101 can be fixed at its side in the width direction as shown in Fig. 6. That is, the claw portion 311c can be fitted near the end of the elongated hole 101a of the floorboard material 101, and the portion of the floorboard material 101 that extends from the end of the elongated hole 101a to the side in the width direction can be held down.
