Description

[Detailed explanation of the invention] (Target of the invention/Field of industrial application) This invention relates to the improvement of temporary supports used in construction works, etc., and is used for passages for workers in construction works, scaffolding for temporary frames, etc. Ru.

(Prior art) Conventionally, for example, Japanese Patent Laid-Open Publication No. 1973-
As described in Japanese Patent No. 61139, four U-shaped receiving members for connecting a stay are welded to the outer circumferential surface of a cylindrical support main body. However, with this support, it takes time and effort to weld the four U-shaped receiving members to the support main body, which increases manufacturing costs, and the maximum number of support members that can be attached is limited due to the circumferential size of the support main body. There is.
Furthermore, even if the support is installed upright, the stay may not be connected to the support member. In this case, the support member serves as a step for people to put their feet on, but in the conventional support member described above, the support member Since it is not continuous all the way around, there is a risk of tripping, and the tread surface is not flat and uneven, making the footing of the worker unstable.
Moreover, there was a risk of causing pain to the soles of the feet.

As another conventional example, as seen in Japanese Patent Publication No. 54-36407 or Japanese Patent Application Laid-Open No. 55-49457, a ring-shaped flange member is welded to the outer peripheral surface of the support column body, and a stay is connected to the flange member. A large number of engagement holes are provided for this purpose. In these struts, the outer periphery of the flange member is circular, so when welding multiple flange members to one strut body, it is difficult to align the circumferential position of each engagement hole, and special It requires jigs and tools and is time-consuming.
Furthermore, when these pillars are laid down and stacked on a roof or the like, there is a risk that they will roll because the outer periphery of the flange member is circular, so it is necessary to tie them with wire or the like to prevent them from rolling.

(Purpose of the invention) The present invention was made in view of the above-mentioned circumstances, and is capable of connecting a large number of stays when installed upright, and also serves as a step when the stays are not connected. The object of the present invention is to provide a temporary support support that is free from the risk of rolling even when placed on its side and is inexpensive to manufacture.

(Structure of the invention) In the present invention, a plate-shaped flange member is fixed to the outer peripheral surface of a cylindrical support main body, and the flange member is provided with an engagement hole for connection with other members such as a stay. In addition, the flange member is characterized in that linear side portions are formed at a plurality of locations on the outer periphery of the flange member.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the strut 1 shown in FIGS. 1 and 2, 2 is a cylindrical strut body, and ring-shaped end plates 3 are provided on both end surfaces of the strut body 2, and plate-shaped end plates 3 are provided on the outer peripheral surface 2a. The flange members 4, 4 are fixed by welding. The flange members 4, 4 have a regular octagonal outer circumferential shape, and a round hole 5 is provided in the center thereof, and the support main body 2 passes through this round hole 5 and is welded to the entire circumference. A rectangular engagement hole 7 is provided between each side portion 6, 6... of the outer periphery of the flange member 4 and the round hole 5 for inserting a wedge, for example, for connection with another member such as a stay. There is. The flange members 4 are manufactured, for example, by press punching a metal plate, and are fixed to the support main body 2 at fixed positions so that the circumferential positions of the respective flange members 4 are at the same angular position. When fixing this flange member 4, by laying down the support main body 2 and placing one side 6 of both flange members 4, 4 on a flat surface plate, it is possible to easily align them to the same angular position. I can do it.

A method of using the above-mentioned support column 1 will be explained. As shown in FIG. 3, columns 1, 1, . . . are vertically erected, and a stay 8 is installed between each column 1. In FIGS. 4 and 5, the stay 8 has connection parts 10, 10, which are approximately L-shaped in side view, welded to both ends of a tube 9, and the middle of the horizontal part 10a of the connection part 10 is A rectangular through hole 11 is provided for inserting a wedge 12, which will be described later. Further, the length of the horizontal portion 10a is determined from each side 6 of the flange member 4 to the support main body 2.
The length is approximately the same as the length to the outer circumferential surface 2a.
A wedge 12 is inserted into the connecting portion 10 across the respective through holes 11 and the engagement hole 7 while in contact with the flange member 4 . As is clear from FIG. 4, the through hole 11 of the horizontal wall portion 10a is located at the tip portion 10b.
The side closer to the side 6 of the engagement hole 7 of the flange member 4 comes into contact with the wedge 12, respectively, and the engagement hole 7 and the through hole 11 meet this condition. The size and location meet the requirements.

The wedge 12 connects the flange member 4 and the connecting portion 10.
are attracted to each other, so that the tip portion 10b and the outer circumferential surface 2a and the vertical portion 10c and the side portion 6 are in contact with each other, or in a state where they are close to contact. That is, if the dimensional accuracy of the flange member 4 and the connecting part 10 is high, they will come into contact at the same time, and if the dimensional accuracy is low, they will come into contact after some distortion occurs in each part, or they will come into contact with a very small gap. Therefore, rotation of the stay 8 in the horizontal plane is restricted by the contact between the side portion 6 and the vertical portion 10c.

In this way, by connecting the plurality of stays 8 using each side 6 and the engagement hole 7,
The assembled product becomes strong. Since the side portions 6 and the engagement holes 7 can be formed in any number, it is possible to connect a large number of stays 8, and by making the dimensions and shapes of the engagement holes 7 various. Therefore, it is also possible to connect stays 8 having different shapes. In addition, when installing the struts 1, it is desirable to match the circumferential angular position of each strut 1, but this can be easily done by aligning the sides 6 of the flange member 4. It can be adjusted to Stay 8
If not connected, each flange member 4 becomes a formal step. When the support column 1 is laid down for storage or temporary storage, it is stable if the sides 6 of the flange member 4 are in contact with the storage area so that there is no risk of it rolling over. In manufacturing this strut 1, since the flange member 4 has a regular octagonal shape, it can be effectively stamped from a flat iron plate, and there is no wastage of material.
The angular position in the circumferential direction when fixing to can be easily adjusted, and since the outer peripheral surface 2a is welded all the way around, the strength is increased.

6 and 7 show other embodiments of the stay. The stay 13 shown in FIG. 6 has a wedge 15 fixed to the end of a tube 14.
are fitted into the engagement hole 7 and connected. The stay 16 shown in FIG. 7 has a guide groove 1 through which a wedge can be inserted.
A tip fitting 17 having a diameter of 7a is fixed to the tip of the tube 18, and with this tip fitting 17 engaged in the engagement hole 7, a wedge 19 is driven between the guide groove 17a and the engagement hole 7. It is designed to be connected.

In the above embodiment, a regular octagonal flange member 4 is used, but the flange member 4 may be a rectangle, a square, or another regular polygon. Further, although not shown, the engagement hole formed in the flange member may have a shape that reaches as far as the outer circumferential surface 2a of the column main body 2.

(Effects of the invention) The invention has the following unique effects.

Since the plate-like integral flange member provided with the engagement hole need only be fixed to the support main body, the manufacturing cost is extremely low.

An arbitrary number of engagement holes can be provided in the plate-shaped flange member, thereby making it possible to connect a large number of stays. The member can be fixed, and an engagement hole of the required size can be formed therein.

The engagement hole provided in the plate-like flange member can have various dimensions and shapes, thereby making it possible to connect stays of different shapes.

The flange member fixed to the strut body is made of a plate-like integral piece, so it serves as a step when the stay is not connected to the flange member. It is safe because there is no chance of stepping on the foot, and since the tread surface is flat, the feet of the worker are stable, and since the tread surface is not uneven, there is no pain to the soles of the feet.

When installing a large number of columns in parallel, it is desirable to match the circumferential angular position of each column.
In this case, alignment can be easily performed by aligning the linear sides of the flange members of each support.

When fixing a flange member with multiple engagement holes to a strut body, the mounting angle of the flange member in the circumferential direction relative to the strut body must be adjusted. By aligning the side portions and fixing them in place, the mounting angle can be adjusted accurately.

When the column is placed on its side, the straight sides of the flange member hold the column in a stationary position and there is no risk of it rolling.

Furthermore, according to the present invention, since the plate-shaped flange member is provided with linear side portions at a plurality of locations on the outer periphery, each plate-shaped flange member is The engagement holes provided in the plate-shaped flange members must be aligned in the vertical direction, and in this case, the plurality of sides of each plate-shaped flange member must be aligned and fixed in such a way that the orientations of all sides are the same. This allows the engagement holes of each plate-shaped flange member to be easily and accurately aligned concentrically.
