Description

  The present invention relates to a metal fitting for extending a construction sheet useful for stretching various construction sheets used in the construction, repairing, dismantling, painting, and the like of buildings.

  In construction sites, etc., a steel pipe (hereinafter referred to as a single pipe) that surrounds a construction building is assembled with a scaffold, and the scaffold is a sheet-like material (hereinafter referred to as a cloth, net, net, etc.) A construction sheet or simply a sheet). The scaffold includes scaffolds such as one-side scaffolds and framework scaffolds in addition to single-tube scaffolds.

  The sheet stretched on the scaffold formed of a single pipe is provided with a tension eyelet on the outer periphery of the sheet at an equal pitch. Since it is a method of binding, there are problems that it takes time to bind and that troublesome work is also required to remove the sheet. Conventionally, a construction sheet tensioning method improved in this respect and a tensioning tool used in this method have been proposed in Patent Documents 1 to 3 and the like.

  Adopting such a method of stretching the sheet allows the sheet to be stretched in a tensioned state, so that not only the appearance is good, but the lighting and ventilation are also good, especially in people in condominiums and offices. It was suitable for stretching a net-like sheet to be stretched on a scaffold for repairing while living or using the office.

  However, the rail-like tensioning tool disclosed in the above-mentioned Patent Documents 1 to 3 is provided with a slider that allows the eyelet of the seat to be hooked on the rail-like main body, so that the eyelet of the seat is attached to the slider. Although it was a technique that eliminated the binding work with the string only by hanging, the problem to be solved still remained in order to attach the rail-shaped main body to the horizontal single pipe of the scaffold. That is, since the rail-shaped extension tool is provided with a long hole at an appropriate pitch in the length direction, and the long hole must be attached to a horizontal single pipe through a wire, a rope or a belt with a buckle, etc. There remains a problem in the work of attaching or removing the rail-like extension tool to the single pipe of the scaffold by means of a rope or wire.

  On the other hand, when laying construction sheets, there are meter-sized sheets (width is in meter units) and inch-sized sheets (width is in inches), so which size sheet should be stretched? It is known that the installation interval of single pipes for assembling scaffolds is also different.

  In view of this point, the inventor of the present invention can first attach the construction sheet to a pin without wrinkles, and slide the stretched sheet like a curtain so that it can be opened and closed. Not only can it be installed, but it can also be installed with the same member, even if it is a vertical single pipe with a different standing pitch, such as a meter-size seat scaffold or an inch-size seat scaffold. Patent Document 4 proposes a seat tensioning tool comprising a joint rail having a structure that enables the rail and a rail bracket for supporting the rail on a single pipe.

  However, with the previously proposed sheet tension tool, there are still insufficient points to stretch and stretch the sheet on the scaffold, so in the present invention, any sheet of meter size or inch size can be used. It is possible to mount a rail body that can be hooked, and of course, to provide a seat tensioning bracket having a structure that enables position adjustment in the vertical direction to stretch the tensioning sheet. As a result, the idea was completed.

  In order to solve the above-mentioned problems, the present invention is intended to solve the above-described problem of the present invention.

A mounting member having a rail mounting portion formed so as to mount a longitudinal end portion of a rail body having a slider capable of locking the eyelets of the upper and lower ends of the sheet is provided on the outside. It is.

In the above configuration, the front surface of the bracket and the back surface of the mounting member can be coupled by bolting. Further, the portion of the mounting member where the eyelet pin is provided extends to the lower side of the forming member with a left-right width including the eyelet pin, and is bolted to the bracket in an elongated hole formed in the extended portion, and the mounting member is attached to the bracket. There is a form of positioning by moving up and down with respect to.
Further, the eyelet pins may be provided with two pairs of eyelet pins, each having a pair of left and right pairs of upper and lower ends on the tip side of the hook-like member or hook-like member.

  In the present invention, a bracket made of a generally U-shaped or inverted U-shaped member is provided on the front surface of the fixed portion of the clamp formed so that the movable portion is a jaw opening and closing type and can be fixed to a single pipe for scaffolding. A pair of left and right hook-shaped eyelet pins for engaging the outer edge eyelets at the upper and lower ends of two adjacent sheets on the front surface of the bracket; Since the seat mounting bracket is configured by providing an attachment member provided with a rail attachment portion formed so as to attach an end portion in the length direction of the rail body provided with a slider capable of locking the eyelet of the end portion, It can be attached to both vertical single pipes of the scaffolding with different standing positions assembled for meter size and inch size construction sheets that differ slightly in the width direction. , Be a sheet of either of the width size can be stretched the sheet to the scaffold in a taut in the same specification.

The nut 5b is tightened by adjusting the position in the vertical direction.

  5 to 7, the rail support portion 6a can be finely adjusted in the left-right direction with the auxiliary piece 61a protruding in a wing shape on the upper and lower sides and the rail body R mounting position. A mounting hole 62a formed by a horizontally long hole is provided so as to be able to. Here, in order to absorb the difference due to the difference in the standing position that the standing position of the vertical member 1v differs depending on the type of the sheet 2 (meter size and inch size), the mounting hole 62a by the long hole is Is formed.

  The first example of the inventive metal fitting MC described with reference to FIGS. 5 to 7 is a metal fitting having downward eyelet pins 6b for engaging the eyelets 2a on the lowermost side of the stretched sheet 2. FIG. The second example of the present invention MC shown in FIGS. 8 and 9 differs from the metal fitting MC of the first example in the following points.

  That is, in the second example of the inventive hardware MC shown in FIGS. 8 and 9, first, in addition to the two downward eyelet pins 6b and 6b, the pin 6b, Two upward eyelet pins 61b and 61b are provided below 6b. Next, it does not have the structure of the adjustment part 6C of the attachment position provided with the metal fitting MC of the first example of FIGS. In these two points, the second example of the inventive metal fitting MC of FIGS. 8 and 9 is different from the metal fitting of the first example of FIGS. 8 and 9, the same reference numerals are used for the same members and parts as those in the examples of FIGS. 5 to 7.

  The second example of the inventive fitting MC of FIGS. 8 and 9 includes a single pipe that forms the vertical member 1v corresponding to the position where the uppermost horizontal rail 3h is provided in the scaffold Ws of FIGS. The clamp 4 is attached and fixed. 1 and 2 is supported by the bracket MC of FIGS. 8 and 9 except for the eyelets 2a in the middle portion excluding the eyelets 2a at both outer ends of the uppermost side of the seat 2 stretched on the scaffold Ws of FIGS. The eyelet pin P of the horizontal rail 3h is locked, and the eyelet 2a at the outer end is locked to the upward eyelet pin 61b of the metal fitting MC.

  In this way, the eyelets 2a on the uppermost side and the lowermost side of the sheet 2 in which two sheets in FIG. 1 and FIG. 2 are connected in tandem are respectively connected to the uppermost and lowermost horizontal rails 3h and the inventive bracket MC. Lock to eyelet pins P, 6b, 61b.

  In the stretched state of the sheet 2, in order to stretch the two sheets 2 connected in series on the scaffold Ws, in this embodiment, the horizontal rail 3h supported by the lowest bracket MC is pulled downward. Fixed (moved downward and fixed).

  For this reason, the seat 2 is lowered by loosening the nut 5b and pulling down the mounting member 6 attached to the bracket 5 of the clamp 4 via the long hole 6d and the bolt nuts 5a and 5b through the hole 6d. Uplift and then tighten the nut 5b to fix this state. 6 and 7 show a state in which the position of the attachment member 6 is lowered to the maximum with respect to the clamp 4 and the bracket 5.

  In this way, the tandem connecting sheet 2 stretched on the scaffold Ws has the upper and lower eyelets 2a engaged with the eyelet pins P of the upper and lower horizontal rails 3h on the scaffold Ws, respectively. Since the eyelets 2a at both the left and right outer ends of the upper and lower sides of the seat 2 are engaged with the downward eyelet pins 6b and the upward eyelet pins 61b provided in the mounting member 6 of the inventive metal fitting MC at the lower end, The supported horizontal rail 3h at the lower end can be adjusted and moved downward together with the mounting member 6 on the metal fitting MC so as to be positioned and fixed, so that the seat 2 can be stretched on the scaffold Ws. It becomes possible.

  In order to adjust and displace the lowermost horizontal rail 3h by the rail body R having the eyelet pin P that engages the eyelet 2a on the lower end side of the seat 2 downward on the metal fitting MC while the seat 2 is stretched, The action part (front end side) of the ratchet type tension machine TM is connected to the connection hole 6e provided in the adjusting part 6c of the inventive metal fitting MC, and the rear part of the tension machine TM is coupled to the lowermost fixed horizontal member 1h. In this state, the tension machine TM is installed between the metal fitting MC and the horizontal member 1h. As shown in FIGS. 1 and 2, the tension machine TM is arranged at both left and right outer ends of the lower end portion of the tandem connection sheet 2, and operates both the left and right machines TM at the same time in the full width of the sheet 2. The vertical tension is applied, that is, the mounting member 6 of the inventive metal fitting MC is applied to the clamp 4 and the bracket 5 so as to be pulled down together with the horizontal rail 3h.

  In the present invention, the seat 2 stretched on the scaffolding Ws is engaged with the eyelets 2a on the upper and lower ends thereof on the eyelet pins P of the horizontal rail 3h and the eyelet pins 6b and 61b of the inventive metal fitting MC that supports the rail 3h. Therefore, when the tension of the tensioning machine TM is released and the eyelets 2a at the outer ends of the upper and lower ends of the seat 2 are removed from the eyelets pins 6b and 61b of the bracket MC, the eyelets 2a are locked to the eyelets pins P of the horizontal rail 3h. The sheet 2 can be opened in the horizontal direction as if it were a curtain between the upper and lower horizontal rails 3h, 3h.

  The first example and the second example of the inventive metal fitting MC described with reference to FIGS. 5 to 7, 8, and 9 are useful metal fittings used when the sheet 2 is stretched on the flat surface of the scaffold Ws. The convenience of the bracket MC in the present invention is also useful for the bracket when the sheet 2 is stretched at the corner portion of the scaffold Ws that turns 90 degrees, and is therefore stretched at the corner portion of the scaffold Ws below. An example of the inventive metal fitting MC that is useful when applied to the sheet 2 will be described with reference to FIGS.

A third example of the inventive metal fitting MC shown in FIGS. 10 to 12 is a corner metal fitting having a height adjusting function, and corresponds to the first example of the inventive metal fitting MC described above with reference to FIGS. It is.
Further, the fourth example of the metal fitting MC for corners shown in FIGS. 13 and 14 corresponds to the second example of the metal fitting MC that does not have the height adjusting function described above with reference to FIGS.

In each of the inventive brackets MC in the corresponding relationship, the difference between the inventive bracket MC of the example described with reference to FIGS. 5 to 9 and the inventive bracket of the examples of FIGS. The two points are that the planar shape of the bracket 5 attached to 42 is different, and therefore the planar shape of the attachment member 6 attached to this bracket 5 is also different.
4 to 6 and the third embodiment of the present invention MC shown in FIGS. 10 to 12 are height-adjusted even though there is a difference in use between the flat section and the corner section. 7 and FIG. 8, the second embodiment of the present invention fitting MC and the fourth embodiment of the present invention fitting MC of FIG. 13 and FIG. 14 are also for the flat portion and the corner portion. Even though there is a difference, there is a common point that it does not have a height adjustment function.

  Therefore, the third example of the inventive metal fitting MC shown in FIGS. 10 to 12 and the fourth example of the inventive inventive metal fitting MC shown in FIGS. 13 and 14 are also shown in FIGS. 5 to 7 and FIGS. The same reference numerals are used for the same members and parts as those of the inventive metal fitting MC described in the above.

  Since the present invention sheet mounting bracket is as described above, it is extremely useful as a bracket for stretching a construction sheet stretched on a scaffolding formed of a single pipe or the like in a state of being pinned to the scaffolding. .
