Description

The present invention relates to a connecting pin for a frame scaffold for connecting the ends of both pedestals corresponding to the top and bottom of two vertically stacked building frames, and a frame scaffold attachment structure using the connecting pin. It is a thing.

The framework scaffolding is installed close to the outer wall of the building to be constructed at the construction site, and is mainly used as a scaffolding when constructing the outer wall of the building. In the description of the present application, "left and right" is a direction along the horizontal direction with respect to the outer wall of the building, and "front and back" is a direction of approaching and separating from the outer wall of the building in the vertical direction.

As shown in FIG. 7, in a general building frame 1 used for a frame scaffold, the upper ends of a pair of front and rear pedestals 11 and 11 are connected to each other by a horizontal member 12, and the pedestals 11 and the horizontal The reinforcing frame 13 is attached so as to straddle the frame member 12. There are several types of building frames 1 of this type having different intervals between the pair of pedestals 11 and 11.

The pedestals 11 and 11 of the building frame 1 are made of pipes, and the upper and lower ends of the pedestals 11 are open (see reference numerals 15 and 16 in FIG. 8).

Then, in this building frame 1, a plurality of building frames 1 are laminated vertically to form a frame scaffold as shown in FIG. 9, but in order to stack the building frames 1 and 1 vertically, as shown in FIGS. 7 and 8. The ends of the pedestals 11 and 11 on each side corresponding to the upper and lower sides are connected by connecting pins 4 and 4, respectively, and are sequentially laminated up to a predetermined layer. Although not shown, the building frame stacking form shown in FIG. 9 is constructed as an integral frame scaffold having predetermined areas on the top, bottom, left and right by connecting adjacent building frames on the left and right with braces (FIG. 2). reference). Further, a cloth plate for an operator to walk is erected between the horizontal members 12 and 12 of the building frames 1 and 1 adjacent to the left and right (see reference numeral 2 in FIG. 2).

By the way, most of the height A (see FIG. 7) of a general building frame 1 on the market is standardized to 1700 mm. On the other hand, as shown in FIG. 8, the connecting pin 4 for connecting the pedestal column, which has been conventionally used, has a predetermined length U (U = about 100 mm) above and below the short portion 41 having a short and small length S (S = 25 mm). ) Are integrally formed with the insertion portions 42 and 43.

The short diameter portion 41 of the connecting pin 4 has the same outer diameter as the outer diameter of the pedestal 11 (for example, about 43 mm), and the upper and lower insertion portions 42 and 43 are inserted into the upper opening 15 and the upper pedestal 11 of the lower pedestal 11. It functions as a stopper for determining the insertion depth U (U = about 100 mm) when each of the lower openings 16 of the above is inserted. Then, from the viewpoint of making the entire connecting pin 4 compact, the length of the short portion 41 is standardized to a short and small length S (S = 25 mm) as much as possible.

In the frame scaffolding constructed by using the building frame 1 having the overall height A and the connecting pin 4 having the short portion 41 having the short and small length S, as shown in FIG. 9, each floor (per first floor) The height A'is 1725 mm, which is A (1700 mm) + S (25 mm). Since each layer of the framework scaffold is laid with a cloth plate (thickness is about 30 mm), the actual effective height of each layer is less than 1700 mm.

However, many workers are over 1700 mm tall, and such tall workers need to bend down when working or walking on the cloth boards of each level of the framework scaffolding. Therefore, there is a problem that the posture becomes cramped when working on the cloth board or walking.

On the other hand, conventionally, there has been a demand for the height of each building frame to be slightly higher than the height of a tall person. Then, as a known example in which the height of the building frame can be adjusted, for example, there is one disclosed in Patent Document 1 (Utility Model Registration No. 3017061). In this Patent Document 1, each of the front and rear pedestals of the building frame is composed of two pipes divided into upper and lower parts, and the upper and lower pipes are made into an inner pipe and an outer pipe having different diameters, and both pipes can be expanded and contracted. The overall length of the pedestal can be adjusted by inserting it into the pipe and fixing both pipes with pins at any fitting position.

Further, among the known framework scaffolds, for example, as disclosed in Patent Document 2 (Japanese Unexamined Patent Publication No. 2014-98303), small articles (for example, bolts) near the edge of the cloth plate (scaffold plate) of each layer. Etc.) are attached with scaffolding to prevent them from falling. The width strip used in Patent Document 2 is provided with a vertical hook that locks to a horizontal member and a horizontal hook that locks to a pedestal at both ends thereof. Then, by locking the vertical hooks and horizontal hooks (4 hooks in total) on each side to the horizontal member and the pedestal, respectively, this brazier can be assembled in a stable posture near the edge of the cloth plate. it can.

Utility Model Registration No. 3017061 Japanese Unexamined Patent Publication No. 2014-98303

However, as in Patent Document 1 above, in order to adjust the height of the building frame, each pedestal of the building frame is divided into upper and lower parts so that both pipes can be expanded and contracted. Although the height can be adjusted to the desired height, the number of members increases and the number of members increases due to the fact that the pedestal is divided into two upper and lower pipes and that fixing pins are required to fix both pipes. There is a problem that the work for adjusting to a predetermined length (alignment of pin holes of both pipes and insertion of pins) is troublesome.

On the other hand, in the above-mentioned Patent Document 2, a width bar for preventing small articles from falling off is assembled near the edge of the cloth board of each layer, but in order to assemble this width bar in a stable posture, the width is used. Since two assembly tools (vertical hook and horizontal hook) are attached to each end of the tree, the number of assembly tools (hooks) is large (4) and the installation work of those assembly tools is easy. In addition to being necessary, there is a problem that the assembly work becomes complicated because it is necessary to lock each assembly tool (two each) at both ends of the drawstring to the horizontal member and the pedestal respectively. It was.

Therefore, in view of the above circumstances, the present invention devises a connecting pin for connecting the pedestals of both building frames to be laminated vertically so that the building frame height of each layer can be increased to a desired height.

Insert until the lower ends come into contact, and then fit the lower opening 16 of the pedestal (upper pedestal) 11 of the second-stage building frame 1 to the upward insertion portion 53 of the connecting pin 5, and the upper pedestal 11 Can be connected to the lower pedestal 11 in a state of being raised by the length T (T = 200 mm) of the raising length portion 51. In this way, the lower pedestal 11 and the upper pedestal 11 are connected to each other by using the connecting pin 5 for the front and rear pedestals 11 and 11 of the building frame 1, and similarly, the lower pedestal 1 and the lower pedestal 1 Each of the upper building frames 1, 1 ... is connected to 1 ... At this time, the two adjacent connecting pins 5, 5, ... Are installed with the locking ribs 54, 54 on each side facing each other on the left and right (and front and back).

Hereinafter, similarly, the pedestals 11 of the building frame 1 on the upper stage side are connected by a predetermined number of stages via the connecting pin 5 on the pedestal 11 of the building frame 1 of the existing stage, and the adjacent left and right sides at the same height are further connected. By fitting the engaging grooves 61, 61 at the ends of the scaffolds 6, 6 ... Between the locking ribs 54, 54 of the connecting pins 5, 5 from above, as shown in FIGS. 2 and 3, respectively. It is possible to construct a frame scaffold with the shown braid. In this case, if the width tree 6 used has a different color for each layer, the layer of the framework scaffold can be easily identified. In the frame scaffolding of FIGS. 2 and 3, the details of the vicinity of each connecting pin 5 have a simple structure as shown in FIGS. 4 to 6.

Then, when the framework scaffolding is constructed by using the connecting pin 5 of the embodiment of the present application in this way, the following various effects can be obtained.

First, in the frame scaffolds of FIGS. 2 and 3 constructed by using the connecting pin 5, the height B of each layer is set to the height A (A = 1700 mm) of the standard building frame 1. The total height is 1900 mm including the height T (T = 200 mm) of the long portion 51 for raising the connecting pin 5, and even a tall worker (for example, a height of 1800 to 1900 mm) can work without bending on the cloth plate 2. Can be done.

Secondly, since the raising connecting pin 5 has a simple structure in which the insertion portions 52 and 53 are provided above and below the raising long portion 51, respectively, it is inexpensive as a means for raising each layer of the framework scaffold. Moreover, handling (assembly work) becomes easy.

Thirdly, in the case where the connecting pin 5 is used, a vertically oriented locking rib 54 capable of engaging and disengaging the end portion 6a of the width bar 6 is provided on the outer surface of the raising length portion 51. Therefore, the connecting pin 5 can be effectively used as a member for locking the end portion of the width bar 6 in addition to the function for merely connecting or raising.

Fourth, since the locking ribs 54 are provided at least at two positions facing each other on the outer surface of the raising length portion 51, the width bars 6 and 6 on each side of one connecting pin 5 are provided on the left and right sides, respectively. The ends 6a and 6a can be engaged (one connecting pin 5 can be efficiently used for attaching a skirt).

Fifth, if the locking ribs 54 for engaging the end of the skirting bar in the connecting pin 5 are provided at four locations at an angle of 90 ° in the circumferential direction on the outer surface of the elongated portion 51 for raising, 1 Two connecting pins 5 are used to mount two width bars 6 and 6 on both the left and right sides (angle 180 ° direction) of the connecting pin 5, and two connecting pins 5 at an angle of 90 °. It can be applied to the usage patterns in which the skirts 6 and 6 are attached, and the usage patterns for mounting the skirts increase.

Sixth, in order to mount the drawstring 6 between two adjacent connecting pins 5, 5, both ends of the drawstring 6 are attached to the opposing locking ribs 54, 54 of both connecting pins 5, 5. This can be done by fitting (dropping) the engaging grooves 61, 61 provided in the above from above. Therefore, it can be carried out with a simple configuration and a simple operation to attach the width bar 6.

Although not shown, in order to prevent the connecting pin 5 from spilling from the hand and accidentally falling when disassembling the frame scaffolding, the connecting pin 5 is attached to the raising length portion 51 portion of the connecting pin 5. While one end of a rope such as a thin chain or a thin wire is connected, a locking tool such as a hook that can be locked at an appropriate position in the structure of the building frame 1 (for example, the reinforcing frame 13) is attached to the other end of the rope. It is good to keep it.
