Description

  TECHNICAL FIELD The present invention relates to a scaffolding skirting erected on a scaffolding board side edge of a framework scaffold that is installed along an outer wall or the like to be constructed or constructed at a construction site or a construction site.

  In the field of construction work and civil engineering construction work, temporary framework scaffolds are provided for workers to walk and temporarily place tools along the walls to be constructed and constructed. This scaffold is usually fitted with a baseboard called a toeboard along the outer edge of the scaffolding board to prevent workers from stepping on or dropping tools. It is.

  Conventionally, such scaffolding skirting boards are disclosed in Patent Documents 1 to 3. For example, Patent Document 1 discloses an inverted U-shaped locking bracket for fixing a baseboard body having a channel-shaped cross section to a scaffold plate, a retaining bracket for the same, and a hook bracket for fixing to a building frame. There is a proposal for a skirting board. Patent Document 2 proposes a skirting board in which a scaffold plate and a skirting board are clamped by a hook member that can move up and down and fixed by inserting a screw shaft. Further, Patent Document 3 proposes a type of baseboard in which an inverted U-shaped locking metal fitting is inserted into a locking clamp projecting from both end portions of the scaffolding plate and pinched and fixed on a shaft.

  By the way, the size of the scaffolding board is originally standardized by the standard, but the actual situation is that the length, width, thickness, and height differ depending on the manufacturer and the production time (lot). It is. On the other hand, the conventional baseboard is generally structured to be fastened and fixed firmly. Therefore, the conventional skirting boards are not good in workability, and many of them do not cope with the difference in dimensions.

  For example, in the case of Patent Document 1, since the locking metal fittings and retaining metal fittings are firmly fixed to each other by a shaft body, the length direction (horizontal direction) dimension between the scaffolding board and the baseboard is not correct. If this happens, not only will these axially attached states become unstable, but it will also be insufficient because the structure depends only on the resilient force of the spring body as a measure to prevent the baseboard from rising or lying down. It is. Also in Patent Documents 2 and 3, the hook member, the locking metal fitting, and the holding metal fitting absorb the difference in dimensions in the longitudinal direction and the height direction because the focus is on the fastening force. However, there is a problem that there is no sufficient adjustment mechanism for making it unstable and the installation state of the skirting board becomes unstable.

  Further, when the scaffolding skirting boards are stored in a warehouse or the like, a large number of scaffolding skirting boards of several hundred to several thousand pieces must be stored at a time. However, in the scaffolding skirts described in Patent Documents 1 to 3, since various metals and hook members are in the way, it is difficult to stack the skirting boards in the vertical direction or to line them up in the horizontal direction.

  An object of the present invention is to propose a structure of a scaffolding skirting board that can firmly cope with a difference in dimensions of a scaffolding plate and the like and that can be easily attached.

  Another object of the present invention is to lock not only the longitudinal ends of the skirting board but also the substantially central part thereof, thereby ensuring that the skirting board is loosened or dropped off due to lifting or lying down. The object is to propose a structure of scaffolding baseboard with high safety that can be prevented.

  Still another object of the present invention is to propose a scaffolding skirting board that can be properly stacked, arranged and arranged in the vertical and horizontal directions.

While examining the above-mentioned problems that conventional skirting boards have, the inventors have easy attachment to a scaffolding plate and a latch clamp, and have a high degree of freedom in variable adjustment of the attachment state, and the attachment. We have succeeded in developing scaffolding baseboards that are stable and solid. That is, the present invention attaches a locking bracket that slides in the vertical direction and displaces in the horizontal direction to both ends of the base plate in the longitudinal direction with respect to the base plate body, and the base portion in the longitudinal direction of the base plate Includes an oblique slide frame fixed to the outer surface thereof, a fastening tool that is fitted in the oblique groove in the frame and can be moved in an oblique direction, and an upper side edge of the scaffolding plate and the baseboard at the fastening position by the fastening tool. was placed fixing member comprising a fixing plate which is bent so as to be locked to the preparative, Ri Do three point support mechanism, the locking bracket has a bifurcated locking groove at the bottom, A scaffolding baseboard having a long hole-like slide hole through which an elastic bolt is inserted in a central trunk portion and a head portion protruding outward at an upper portion .

(5) The fixing plate of the fixing bracket is provided so as to be accommodated in the box-shaped panel except for the grip portion,
However, a more preferable solution can be provided.

The scaffolding skirting board according to the present invention has the following effects.
(1) The mounting to the scaffolding plate and the latching clamp is easy, and the mounting state is stable. And in the case of such attachment work, attachment with a one-touch feeling is possible, without requiring a special tool.
(2) It has a high adjustment function that allows it to be fitted to any scaffolding plate with different accuracy depending on the manufacturer and lot, while maintaining a high level of mounting and safety.
(3) In addition to the longitudinal ends on both sides of the skirting board, it is in the form of a three-point support that is provided with an anti-lifting metal fitting in the substantially central part, and adopts a clamp (fixing metal fitting) that slides diagonally. As a result, the mounting state does not loosen or lie down so that it does not float or fall off.
(4) Since the locking bracket and the fixing bracket are provided so as to fit within the end face of the skirting board thickness range consisting of box-shaped panels or within the panel, the scaffolding skirting boards are loaded properly in the vertical and horizontal directions.

It is a side view of the fixing metal fitting attached to the center part of the baseboard which concerns on this invention. It is the front view (a) and side view (b) of the diagonal slide frame which concern on this invention.

  The scaffolding skirting board according to the present invention slides up and down in contact with both longitudinal ends of the baseboard body 1 composed of a channel-shaped box-shaped panel having an opening on the outer surface side, in particular with the end face. , A pair of left and right engaging metal fittings 3 and 3 ′ which are fitted into a latching clamp C projecting from the end of the scaffolding plate 2, and at the substantially central part of the baseboard body, in the vertical (lifting) direction thereof, It is characterized in that the baseboard is erected and fixed to the side edge of the scaffolding plate 2 (and thus the building frame F) by three-point support by the fixing bracket 4 that restrains the movement in the left-right (lateral slide) direction. It is one of.

In addition, another feature of the present invention is that there are scaffolding plates having different dimensions due to differences in manufacturers, whether the used fittings are unused, or the like. Even in the case, it is a configuration in which an adjusting mechanism is provided so that these mounting states always match well.
Hereinafter, based on these features, a specific configuration of the baseboard according to the present invention will be described with reference to FIGS.

  The scaffolding skirting board according to the present invention is detachably mounted on the horizontal frame F2 of the building frame F formed by combining the horizontal frame F2 between the vertical members (leg columns) F1 via the latch clamp C. In particular, the scaffold plate 2 is used by standing along the outer edge.

In such a skirting board, the locking metal fittings 3 and 3 ′ slide in the vertical direction in contact with both longitudinal end faces and are also displaced in the horizontal direction corresponding to the longitudinal direction of the skirting board. It is pivotally supported under impact by way of a locking bolt 5b constituting the mounting bolt 5 and a spring 5a. Accordingly, the locking metal fittings 3 and 3 'can be moved against the elastic force of the spring 5a in either the vertical direction or the horizontal direction. It is effective in absorbing the level difference caused by the above without causing a slide failure or instability in the engaged state.

As shown in detail in FIG. 3, the locking metal fittings 3 and 3 ′ have a bifurcated locking groove 3 a in the lower part and a long hole through which the elastic bolt 5 is inserted in the central body part. This is an inverted L-shaped two-pronged wedge-shaped metal fitting that has a cylindrical slide hole 3b and that has a metal fitting head portion 3c protruding outward at the top. Moreover, this fitting, the longitudinal end surface of the skirting body 1, by the locking bolts 5b via a spring 5a, movably and in two directions of the vertical direction and the skirting longitudinal direction (horizontal direction) Tamahatsu It can be installed.

Reason for sliding the anchor fitting 3, 3 'in the vertical direction, the posture shown in FIG. 3, by depressing the fitting head 3c with a finger, the locking groove 3a provided on the lower from the end face of the scaffold board 2 It falls on the protruding latching clamp C (placed on the horizontal frame F2 of the building frame F) and sandwiched, and the baseboard is attached to the scaffolding plate in an upright state. In the present invention, when the locking metal fittings 3 and 3 'are sandwiched and locked by the latching clamp C, the metal fittings themselves are only pivotally supported by the elastic bolts 5 under the impact. This operation can be performed very easily in that the above-described locking operation can be accomplished without using a tool by simply pressing down the metal fitting head 3c with a finger.

Moreover, as is apparent from FIG. 4, the locking metal fittings 3 and 3 'are elastically supported via the spring 5a and are displaced in the longitudinal direction (horizontal direction) of the skirting board. So, for example, even when the size of the scaffolding plate 2 is larger than the length of the baseboard body, it can be pivotally supported even in a state slightly separated from the end face of the baseboard, and at the same time, it can be smoothly moved up and down in this position. The point is that it can be slid. As a result, according to the locking metal fittings 3 and 3 ', as described above, the intended purpose required for the metal fittings can be sufficiently achieved even if the dimensions of the scaffolding plate 2 are different. In addition, when the shape of the metal fitting head 3c is substantially trapezoidal in a plan view, as shown in FIG. 4, the longitudinal direction (horizontal direction) of the skirting board can be displaced in the right or left direction.

  Reference numeral 6 shown in the drawing also functions as a guide plate for assisting the sliding of the locking metal fittings 3 and 3 'in the vertical direction, and 7 is a gap plate that shields the connecting portions of the baseboards. These locking metal fittings 3, 3 'are sized so as to be within the thickness range of the baseboard made of a box-shaped panel.

  In the present invention, the above-mentioned locking metal fittings 3, 3 ′ hold the skirting board main body 1 upright mainly on the outer edge on the scaffolding plate 2 by the action of the locking groove 3 a having the wedge effect of the metal fittings. Although it is useful for forming a wall, it is not possible to completely prevent the fixing of the baseboard, that is, the movement in the vertical direction and the horizontal direction (longitudinal direction) only by the metal fittings 3 and 3 ′. Therefore, in the present invention, the above-described fixing bracket 4 for preventing such movement is necessary.

Such fixing fitting 4, in the substantially central portion of the skirting body 1 of the box-shaped panels, there is for arranged to fit into the box-shaped panel, for securely fixing the baseboard to the scaffolding plate 2 Is. The fixing bracket 4 prevents the skirting board from slacking or moving in both the vertical direction (preventing lifting) and the longitudinal direction (preventing horizontal displacement). As described above, the feature of the fixing bracket 4 is to be able to cope with the case where the size of the scaffolding plate 2 is different, and to fix it firmly without using a tool. In other words, to achieve a structure with good workability.

  In the present invention, as the fixture 4 that can meet such a demand, in the present invention, an oblique slide frame 9 fixed to the outer side surface of the skirting board main body 1 as shown in FIGS. 2 and 5 and the inside of the slide frame 9 in an oblique direction. A fastener 10 composed of a wing nut and a bolt that slides and reciprocates, and the upper and lower ends are bent in opposite directions, with the abutment portion 11a at the top and the gripping portion 11b at the bottom. A fixed plate 11 is used.

  The oblique slide frame 9 is provided with an oblique groove 9a formed in a box shape having an inclination of approximately 30 to 45 ° with respect to the horizontal direction, and the fastening tool is provided in the oblique groove 9a. Ten bolt heads are slidably fitted and accommodated. On the other hand, the fixing plate 11 has a bolt insertion hole for receiving the fastening tool 10 in the upper portion thereof, and at the same time the holding portion 11b is held by the lower surface of the scaffold plate 2, and at the same time, the fixing plate 11 is at a tightening position. The abutting portion 11a is bent so as to abut against the folded upper side edge 1a of the skirting board main body 1 when moving up to the upper limit.

  Then, at the tightening position (the position shown by the solid line in FIG. 2B and FIG. 5A), the skirt nut 8 of the tightening tool 10 is tightened with fingers without using a tool. The main body 1 is in a state where it is firmly erected and fixed on the scaffolding plate 2 without being displaced in the vertical and horizontal directions at all.

  In particular, in the present invention, since the fixing metal 4 is fastened with an oblique slide mechanism, the tightened state is not loosened as compared with the vertical slide or horizontal slide structure, and the wing nut 8 is used. Because it is fastened, a strong tightening force can be obtained without using a tool, and with the adoption of the above-mentioned three-point support method, the baseboard can be firmly fixed, and safety can be improved. It will contribute to securing.

In the present invention, the locking brackets 3, 3 'are elastically pivotally supported on the end faces in the longitudinal direction via the springs 5a. Therefore, when the scaffolding baseboard is stored, the locking brackets 3, 3' are stored. By simply sliding ′ upward, it can be fitted on the end face within the thickness range of the baseboard made of a box-shaped panel. When the fixing plate 11 is stored, the wing nut 8 is loosened, the fixing plate 11 is slid upward, and the wing nut 8 is tightened again. As a result, the fixing plate 11 always fits in the box-shaped panel regardless of the position. As described above, the scaffolding skirting board of the present invention can fit the locking metal fittings 3 and 3 ' on the end face within the thickness range of the skirting board made of the box-shaped panel, and the fixing plate 11 in the box-shaped panel. Can fit. As a result, the scaffolding skirting can be properly loaded and aligned in the vertical direction and the horizontal direction, and the storage area of these metal fittings can be reduced.

  The scaffolding skirting board of the present invention can be used not only in construction work sites and civil engineering work sites, but also in other fields that use scaffolding frames such as other construction sites, event venues, and landscaping work.
