Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a joint support pillar among the pillars for erecting an antenna device, a lighting device, etc. at a high place in the event of an emergency disaster.

BACKGROUND ART In the event of an emergency disaster, it is often necessary to temporarily erect antenna devices, lighting devices, etc. at high places in disaster-stricken areas.

Conventionally, when erecting a joint support column as a support for this type of construction, as shown in Fig. 2, the plurality of strut elements constituting the joint support column 1 are placed approximately horizontally in advance in a wide area on the ground. and splice it together,
The erection device 20 is attached to the top thereof. After that, a plurality of branch lines 2 are attached in three or four directions to the required locations of the joint support column 1, and the other ends of the branch lines 2 in two or three directions adjusted to a predetermined length are attached to, for example, a branch line pile 5.
etc., and raise the remaining branch line to pillar 3.
The pillars were erected by pulling them up using winches or the human power of many people. Alternatively, as shown in FIG. 3, a push-up device consisting of a link mechanism 9 using a lever 8 is used to push up the first support column 11 on which the device is installed on the top of the support column 7 erected on the substrate 6. , the joint support column 1 was erected by repeating the work to connect the next second column element in the completely raised state.

Problems that the invention aims to solve: However, in the event of an emergency, the above-mentioned pillar erection requires easy, reliable, and quick work, and at the same time, there are usually strict restrictions on the installation location. The work of erecting jointed support columns required a large amount of manpower and man-hours, as well as requiring a large space.

Means to Solve the Problems The present invention was developed in view of the above points, and its purpose is to easily and reliably erect the necessary joint support columns even in limited narrow spaces, and in a short period of time. The purpose is to provide a joint support column.

The structure of the present invention to achieve the above object is that in a joint support column formed by sequentially connecting a plurality of column elements, the upper part of each column element has a groove in the end face thereof in a direction perpendicular to the column axis. A fitting part is provided, and a pin that can be fitted into the groove of the fitting part is provided at the lower part, and a support column is vertically suspended above the substrate in order to erect the plurality of pillar elements. Then, in order to sequentially guide each of the support pillar elements, the support pillar elements are pressed in a direction perpendicular to the pillar axis using a plurality of guide rollers and screws inside, and the support pillar elements are pressed in a direction perpendicular to the pillar axis by the friction of the pressing surface. a hollow cylindrical guide portion having a fixture for fixing the strut element;
Consists of branch lines extending in multiple directions.

It is characterized by

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail by way of example with reference to the drawings.

FIG. 1 is a front view showing the main parts of an embodiment of the present invention, in which 11 is a column element of a joint support column being erected;
13 is a guide part with a hollow cylinder shape inside which guides and supports the pillar element 11 in sequence; 13 is a fixture for the pillar element; one or more of them are disposed on the guide part 12; By pressing in orthogonal directions, the friction of the pressing surface is used to temporarily fix the column element 11 during column erection so that it does not slip off, and to prevent the joint support column 1 from rotating after column erection. It is something. Reference numeral 14 denotes a cushioning material fixed to the fixture 13 in order to increase the friction between the column element 11 and the fixture 13 to prevent it from falling off when the column is erected, and to prevent damage to the outer surface of the column element 11 when it is fixed. Reference numeral 15 denotes guide rollers for lifting up the support column element 11, and a plurality of guide rollers 15 are provided at at least two locations on the upper and lower sides of the guide section 12. Reference numeral 16 denotes a support column for maintaining the height necessary for the pillar erection work of the guide part 12, and its lower end is connected to a base plate 17.
It is fixed or inserted so that it hangs vertically. 18 is a first branch line stretched in three or more directions for hanging the guide part 12 and the support column 16 on the ground surface; FIG. 1 shows the branch line in only two directions; This is a branch pile driven into the ground 23 for the purpose of construction. A fitting portion 11a is provided at the upper end of each of the strut elements 11 of the joint support column, and a groove having a half-moon or semi-elliptical cross section is provided on the upper end surface thereof, perpendicular to the column axis. Further, a pin 11b is disposed at the bottom of each element perpendicularly to the column axis and fitted into the groove,
The fitting portion 11a of the next column element to be spliced is fitted, and the pin and groove have a structure that allows them to fit into each other.

Next, the operation of this embodiment will be explained. To erect the joint support column shown in this example, the substrate 17
The guide part 12 fitted to the support column 16 vertically erected above is installed at a predetermined position on the ground surface 23, and the branch piles 19 are equally distributed at three or four places around it and driven into the ground surface 23. Using branch wires 18, the support columns 16 and guide portions 12 are stretched in three or four directions so that they are stably suspended.

Next, the first support element corresponding to the element located at the top of the support element 11 is inserted into the hollow hole of the guide part 12 from the lower part of the guide part 12 along the guide roller 15, so that the upper end of the element penetrates. By the way, a required device 20 (for example, an antenna device,
Alternatively, attach 20) in FIG. 4 and a plurality of second branch lines 21 (21 in FIG. 4) using a lighting device or the like, then lift the first support element to a predetermined height and attach it to the guide part A fixture 13 is used to secure this element so that it does not slip down. Next, the upper fitting part of the second strut element is fitted into the lower part of the first strut element, and the fixture 13 is loosened to lift the second strut element. This operation is repeated the necessary number of times in order, and when the desired height is reached, the lowest support element is installed on the board 17 as shown in FIG.
While fixing the spliced support column 1, the second branch lines 21 stretched in multiple directions are expanded using the branch line piles 22 to complete the erection of the column.

As mentioned above, a joint support column of a predetermined height can be erected in a short time even in a limited narrow space by simple operation. For the said device attached to the upper end of this joint support column, the guide part 1
By loosening the fixture 13 of No. 2, rotating this support to direct it in a predetermined direction, and then fixing it again, wireless communication or light projection can be performed. In addition, after the pillar is erected, the support pillar 16 and the base plate 17 are both connected to the support pillar 1.
In addition to fixing the base of the joint support column, the extension of the first and second branch lines is effective in stabilizing the joint support column.

It goes without saying that the device attached to the upper end of this joint support column may be any of various portable devices that utilize such a column.

Effects of the Invention As explained above, the present invention utilizes a support column vertically installed on a substrate, a guide section equipped with a guide roller and a fixing device, and a multi-direction tension branch line, so that a joint support column can be installed in a limited narrow space. Also, the pillar can be erected easily, reliably, and in a short time, and the extension of the first and second branch lines is effective in stabilizing the joint support pillar after the pillar is erected.
