Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a joint structure for connecting a cross beam member to the upper end of a pillar such as an illumination pillar or a sign pillar.

[Conventional technology]

As shown in FIGS. 7 and 8, a conventional one of this kind has a flange (C) of a joint short pipe (B) which is previously inserted and fixed to the upper end of a columnar body (A), an illuminating lamp, a signboard, and the like. Radial ribs (F) (F) on the flange (E) of the beam member (D) to which the
(F) ... is welded and reinforced to reinforce the flanges (C) and (E) with butt bolts (G) (G) (G).
・ It was fixed by connecting with.

[Problems to be solved by the invention]

However, with this connection, the flanges (C) (E) and the ribs (F) (F) (F), etc. project to the outer surface, which is not aesthetically pleasing, and may be caught during handling of the connection work. There was an occasion. In addition, reinforcing ribs (F) (F) (F)
・ It took time because we had to weld ... Further, during the connecting work, the beam member (D) and the joint short pipe (B) must be butt-horizontally maintained without a gap, so that the work is difficult and the work efficiency is poor.

The present invention solves such a problem and has a beautiful appearance with a substantially smooth surface with no protrusions or steps at the seam, and the connection is a simple work of just bolting with an insertion method. (EN) Provided is a joint structure of columns and beam members that can be connected.

[Means for solving problems]

In order to achieve the above-mentioned object, in the joint structure of the strut and the beam member of the present invention, one end of the opening is closed by the lid (4), and a plurality of bolts are inserted into the outer peripheral surface near both ends at regular intervals. Holes (5), (5), (5), (5) are drilled, and the joint short pipe (2) that is inserted and fixed in the through hole (3) in the upper part of the column (1) and the pipe body (6a) at one end ), A plurality of bolt mounting holes (7), (7), (7), (7) that match the bolt insertion holes (5) (5), (5) (5) on the outer peripheral surface of (6b), Nuts (8), (8), (8) fixed to the inner wall surfaces of the bolt mounting holes (7), (7), (7), (7)
The beam member (6) to which (8) is attached and the tube bodies (6a) and (6b) at one end of the beam member (6) are tightly fitted to the joint short pipe (2), and the bolt insertion hole
Align (5), (5), (5) and (5) with the bolt mounting holes (7), (7), (7) and (7) and insert the bolts (9), (9), (9) and (9). The nuts (8), (8), and (8) (8) are screwed together.

[Action]

Insert one end of the beam member (6) until it hits the lid (4) of the joint short pipe (2), and align the alignment marks (10) and (10 ').
The bolt insertion holes (5), (5), (5), (5) of (2) and the bolt mounting holes (7), (7), (7), (7) of the beam member (6) match. Then, the bolt (9) is inserted into the insertion holes (5), (5), (5), (5) and screwed and fixed to the nut (8).

〔Example〕

Explaining an embodiment of the present invention, (1) is an illumination column made of steel pipe,
A long pillar such as a sign pillar, and (2) is a short joint pipe made of steel pipe orthogonal to the pillar (1) penetratingly fixed to a through hole (3) formed in the upper end of the pillar (1). One end of this short pipe (2) is closed by a lid (4), and bolt insertion holes (5), (5), (5), (5) are drilled at regular intervals in the circumferential direction on the outer peripheral surfaces of both ends. Has been done. (6) is a beam member whose one end is inserted into the joint short pipe (2), and one end of which has an outer diameter that allows a slightly larger diameter expansion pipe (6a) to tightly fit into the joint short pipe (2). , Bolt mounting holes (7), (7), (7), (7) are formed at regular intervals at the one end so as to match the bolt insertion holes (5), (5), (5), (5). There is. (8) is a bolt fixing hole (7) (7), a nut fixed to the inner wall surface of (7) (7) by welding, (9) is a bolt insertion hole (5) (5),
(5) Insert the nut (8) into the (5) and bolt mounting holes (7), (7), (7) and (7).
The joint short pipe (2) and the beam member (6) are integrally connected by a bolt screwed with. (10) (10 ') are the bolt insertion holes (5), (5), (5), (5) indicated on the outer peripheral surface of the other end of the joint short pipe (2) and the outer peripheral surface of the shoulder of the beam member (6). And the bolt mounting holes (7), (7), (7) and (7) are alignment marks, and (11) is a cap put on the top of the column (1).

Explaining an example of use of the present invention configured in this way, the pillar (1) and the joint short pipe (2) are welded in advance at the factory and carried to the site as a unit, and one end of the beam member (6) is connected to the joint short pipe. Lid of
Insert it until it touches (4), and align the marks (10) (10 ')
Align the bolt insertion holes (5) (5), (5) (5) and the bolt mounting holes (7).
Match (7), (7) and (7) and insert bolts (9) (9) and (9) (9),
Threaded with nuts (8) (8), (8) (8), fitting short pipe (2) and beam member
(6) is to be connected.

In addition, in the above-mentioned embodiments, one end of the beam member (6) to be fitted into the joint short pipe (2) is explained as the case where the pipe (6a) is expanded, but the beam member (6 ) The outer diameter of one end of the
A contracted tube (6b) having a size substantially the same as the inner diameter of (2) and tightly fitted may be used.

In addition, as shown in FIG. 1, even if the beam member (6) is fixed to the support column (1) in a cantilevered manner as shown in FIG. Connect the beam member (6) between the upper ends of the short pipe (2) (2)
It may have a structure in which it is fixed in a erected state via. In this case, the cantilever structure can be used as an illumination column or the like, and the structure supporting both ends can be used as a sign column.

[Effect of device]

One end opening is closed by the lid (4), and a plurality of bolt insertion holes (5) (5) at regular intervals on the outer peripheral surface near both ends,
(5) The outer surface of the short pipe (2), which is formed by drilling (5) and is inserted and fixed in the through hole (3) at the upper part of the support (1), and the short pipes (6a), (6b) at one end. A plurality of bolt mounting holes (7), (7), (7) and (7) that match the bolt insertion holes (5), (5), (5) and (5), and the bolt mounting holes (7) ( 7),
(7) A beam member (6) having nuts (8), (8), and (8) (8) attached to the inner wall surface of (7), and a short pipe (6a) at one end of the beam member (6). ), (6
B) is tightly fitted to the short pipe (2) and the bolt insertion holes (5), (5), (5)
Align (5) with the bolt mounting holes (7), (7), (7) and (7), and tighten the bolt (9).
(9), (9) (9) is inserted and the nuts (8), (8), and (8) (8) are constructed so as to be screwed together. Since it is a thing, connecting and disconnecting can be done easily by just a simple work such as bolting, and it is possible to quickly connect the joint short pipe and beam member at the site, and the connection part does not have the flange and rib as in the past, In addition, since there are no steps, it has the effect of being conspicuous and making the appearance beautiful.
