Description

  The present invention relates to a scaffolding tread for erection between building frames that are erected at a predetermined interval in constructing a building scaffold.

  Conventionally, when forming a scaffold for building such as a building, it is customary to install a scaffolding tread in a horizontal state between each of the building frames facing each other with a predetermined number of intervals. And the construction of the footboard for scaffolding is intended to fix the holding metal fittings protruding at both ends thereof by hooking them on the horizontal ridge portion of the building frame.

  By the way, when the scaffolding treads are laid horizontally and in a row between the building frames in the form as described above, gaps are inevitably generated in the opposing portions of the respective end portions of the treads. It becomes. In other words, since the grip brackets are formed on both sides of the both ends of the scaffolding tread, when the projecting grip bracket is hooked on the horizontal heel part of the building frame, the edge of each scaffold tread In the meantime, a spatial gap corresponding to the protruding length of the gripping metal is generated. The existence of such a spatial gap has inevitably caused problems such as a worker getting caught in a foot and causing a serious accident or dropping work parts.

  Conventionally, as a means for solving such a problem, in order to fill the spatial gap, a baseboard-like board material having a length substantially equal to the edge length of the scaffolding tread is used. There is a configuration in which a plate-like plate material is fitted (for example, see Patent Document 1).

JP 2008-50939 A

  When the baseboard-like board material as described above is configured to fill the end space of each scaffolding tread, the scaffolding board is constructed because the baseboard board is a separate member. Since this has to be inserted later, not only is the work for constructing the scaffold complicated, but it also takes time for the work. Furthermore, the baseboard-like plate material must be stored separately from the scaffolding tread, and the storage complexity of having to prepare the quantity according to the scaffolding tread to be used is inevitably involved. It was.

  The present invention is intended to provide a novel scaffold tread that solves such conventional problems.

  The present invention has a structure as described in claim 1, that is, in a well-known scaffold tread main body 1 formed by projecting gripping metal fittings 2 on both sides of both end faces, Since the gap filling material 3 having a side-right triangular shape in which the upper surface 3a is the same horizontal plane as the scaffolding tread main body 1 is configured to be additionally fixed, the plurality of building frames A are interposed. The butt gaps (the gaps between the portions of the building frame A laid on the tubular horizontal member a) of the scaffold treads 1 arranged in a straight line are the gaps fixed to the respective scaffolds treads 1. The filling material 3 covers the gap portion, and the cover state is maintained. Therefore, an accidental drop accident of a part based on the existence of the gap portion, or a fall accident in which an operator catches the foot. Such a situation will be prevented in advance. And since this invention comprised so that the gap filling material 3 for having such an effect | action might be fixedly provided to the footboard main body 1 for scaffolding, it is a conventional product which made this another part (for example, patent document 1) The problems such as the complexity of assembling work and the complexity of parts management, which occur in the above-described (1) described, are completely solved.

  Furthermore, the present invention can be applied to a well-known scaffold tread main body 1, that is, even if the scaffold tread main body 1 is already used, only the gap filling material 3 is additionally fixed to the above. Since it is possible to implement the present invention with such operational effects, the implementation is achieved at low cost.

  The present invention has a structure as described in claim 2, that is, in a known scaffold tread main body 1 formed by projecting gripping metal fittings 2 on both sides of both end faces, at the center of both end faces, A gap filling material 3 having a side-right triangular shape in which the upper surface 3a is the same horizontal plane as the scaffolding tread main body 1 is additionally fixed, and the gap filling material 3 has a length direction.

1 and 2 show a footboard for scaffolding according to the present invention. Reference numeral 1 denotes a scaffold tread main body, and erection gripping metal fittings 2 project from both end portions in the longitudinal direction. Reference numeral 2 a denotes a fixing grip provided on the grip 2.
The scaffold tread main body 1 having the above-described form belongs to a known technique, and the present invention is characterized in that it is additionally applied to such an existing scaffold tread main body 1. .

Reference numeral 3 denotes a gap filling material having a right-sided triangular shape with the upper surface 3a as a horizontal plane, and the upper surface 3a is in relation to the center portion of the front edge 1a of the above-described scaffold tread main body 1 and the scaffold tread main body 1 It is attached so that it may be flush with the upper surface of the same. As shown in FIG. 1, the fixing means is usually fixed based on driving of the rivet 4, but in addition, it is configured to be fixed based on screwing, welding, adhesive or the like. Also good. 4a shows a driving guide hole for the separation.

  In the present invention, it is important that the attachment is additionally performed. In other words, except that the gap filling material 3 is attached at the time of manufacturing the scaffold tread main body 1, the scaffold tread main body 1 already in use is used to improve the attachment to the scaffold tread according to the present invention. Implementation is possible. This is one of the major features of the present invention.

  FIG. 3 shows an example of use showing a state in which the mounting bracket 2 for the scaffolding tread according to the present invention is latched to the tubular horizontal member a in the existing building frame A for building a scaffold. . The existing scaffold building construction frame A is erected in the required number of facing states while maintaining a predetermined interval, and a scaffolding tread is erected between the opposing building frames, so that workers can perform work. It constitutes a scaffold.

  Further, the scaffolds in the assembled state as described above are connected in the vertical direction to the required number of steps so as to be stacked to have a height corresponding to the building object. And in such a case, as shown in FIG. 4, it is necessary to attach the staircase B for scaffolding to go up to an upper scaffold board. The attachment is performed by holding the grip metal fitting b fixed to the lower end of the staircase B with respect to the tubular horizontal member a of the building frame A described above. It is configured so that the grip b of the stairs B is positioned inside the erection grip 2.

  In order that the footboard for scaffolding according to the present invention can be used as shown in FIGS. 3 and 4, the gap filling material 3, which is a gist of the present invention, has the following form. It is constituted as follows.

  That is, the lateral width L of the gap filling material 3 is set to a dimension that makes the inner ring from the interval of the gripping metal b of the staircase B so that it can be positioned between the gripping metal parts b of the staircase B. is important. Furthermore, the width M in the length direction of the gap filling material 3 does not exceed the central axis of the tubular horizontal material a in the building frame A for constructing a scaffold for latching the mounting grip 2 and the tubular horizontal material. It is configured so as to have a size such that its tip is exposed on a. This is because, when a plurality of scaffolding treads are laid side by side in the horizontal direction, the end portions of the gap filling material 3 are not in contact with each other, and are opposed to each other with an interval that is not too far away. This is to prevent the gap between the footboards for scaffolding from being generated so much.

  By the way, although it is the above-mentioned gap filling material 3, it is preferable that the width M in the length direction is about 320 mm and that the lateral width L is about 49,5 mm. It is not limited.

  Furthermore, the gap filling material 3 is formed in a tapered triangular shape, so that the lower surface of the gap filling material 3 is positioned on the upper surface side without contacting the tubular horizontal material a in the building frame A for scaffold construction. It is configured to be able to do.

  In addition, although it is the side surface shape of the said gap filling material 3, it is usual to bend and form one board | plate material as shown in FIG. 5, but it is a triangle pipe based on drawing as shown in FIG. It can also be configured to be formed in a shape. The former is mainly suitable for formation with a steel material, and the latter is suitable for formation with an aluminum material. In addition, as long as the basic conditions as described above can be covered, the present invention can be formed by any means.

The scaffold tread according to the present invention is used in the same manner as an existing tread.
When the scaffolding building frame A is installed on the tubular horizontal member a, the gap filling material 3 covers the installation space, and when the scaffolding staircase B is attached, it is fixed to the lower end of the staircase B. Since the gap filling material 3 is configured so as not to obstruct the latching of the gripping metal fittings b provided, no wrinkles are caused on the assembly of such a scaffold.

  Further, the gap filling material 3 according to the present invention is provided at the same time when the footboard for scaffolding is newly manufactured, but at the time of the implementation for the footboard that has already been distributed, It can be carried out with an adapter fixing work. That is, since the implementation of the present invention can be performed on existing treads, the economic burden for implementation is minimized.
