Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to balcony handrails, stair railings,
Alternatively, the present invention relates to a crosspiece connection structure of an architectural lattice body used as a garden fence, road fence, etc.

[Conventional technology]

This type of architectural lattice crosspiece connection structure is as follows:
As shown in Fig. 6 and Fig. 7, the hollow horizontal bar 01
A flange 02 protruding from one side is formed with notches 04, 04 for plug-in connection that can fit into a pair of opposing sides of a hollow vertical bar 03. , 04 flange part 0
2a is formed with recesses 05, 05 that open toward the longitudinal direction of the horizontal bar 01, and the vertical bar 03 has protrusions 06 that hold the flange portion 02a from both sides of the horizontal bar 01 in the width direction. and a retaining protrusion 07 that engages with the recesses 05, 05 are formed by caulking. (For example, Utility Model Application Publication No. 60-41449).

In the case of this conventional crosspiece connection structure, the horizontal crosspiece 01
After inserting the vertical beam 03 into the notches 04, 04 of the flange 02, the holding protrusion 06 and the retaining protrusion 07 must be formed by caulking on site. Since the other flange parts 02b, 02b located close to 02a get in the way of caulking, much labor and effort is required for construction on site.

[Problem that the invention attempts to solve]

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to make the entire crosspiece connection structure sturdy, while also making it possible to perform on-site construction efficiently and easily. be.

[Means for solving problems]

The characteristic configuration of the crosspiece connection structure of the architectural lattice body according to the present invention is that a reinforcing part with a width larger than the wall thickness of the flange is connected to the tip of the flange protruding from one side of the hollow horizontal crosspiece. A notch is formed between the reinforcing portion and the flange to allow insertion and connection of a hollow vertical bar, and the vertical bar has flange portions located on both sides of the notch of the flange of the horizontal bar. A flange that fits externally is provided in series, and when the vertical bar is inserted into the notch of the horizontal bar to a predetermined position, the flange has an elastic part at the step where the flange and the reinforcing part are connected. The main feature is that a retaining piece is provided that engages with the holder, and its functions and effects are as follows.

[Effect]

In other words, although it can be assembled by simply inserting the vertical beam into the notch of the horizontal beam to the specified position, any misalignment in the longitudinal direction of the horizontal beam will occur due to the flange and reinforcement part of the horizontal beam and the vertical beam. The displacement movement of the horizontal beam in the width direction can be reliably prevented by the wide surface contact between the flanges and reinforcing portions of the horizontal beam and the flanges of the vertical beam. In addition, the removal movement of the vertical bar is made strong due to the engagement of the stepped part formed in the strong connection between the flange of the horizontal bar and the reinforcing part with the retaining piece provided on the flange of the vertical bar. can be prevented.

[Effect of idea]

Therefore, it is not only possible to eliminate the need to process the horizontal and vertical beams on-site, but also the number of assembly steps can be greatly reduced, making on-site construction more efficient and easier than in the past. I can do it. At the same time, it has been possible to structure the connecting portion between the horizontal beam and the vertical beam to be sturdy.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figures 1 to 3 show a crosspiece connection structure for an aluminum balcony handrail, which is an example of an architectural lattice. A flange 2 is provided in a protruding manner, and a solid reinforcing portion 3 having a width slightly larger than the wall thickness of the flange 2 is connected to the tip of the flange 2 . This horizontal bar 1, flange 2 and reinforcement part 3
is integrally formed by extrusion molding of aluminum, and a notch 5 is formed across the flange 2 and the reinforcing portion 3 to allow a hollow vertical beam 4 to be inserted and connected.

The vertical beam 4 is provided with flanges 6, 6 that fit onto the flange portions of the flange 2 of the horizontal beam 1, located on both sides of the notch 5, respectively, and the flanges 6, 6 further include: Vertical bar 4 in cutout 5 of horizontal bar 1
When the flange 2 is inserted into the specified position, the flange 2
A retaining piece 7 that elastically engages with the stepped portion a of the continuous portion between the reinforcing portion 3 and the reinforcing portion 3 is integrally formed by stamping. The vertical beam 4 and the flanges 6, 6 are also integrally formed by extrusion molding of aluminum.

Therefore, the vertical bar 4 can be assembled by simply inserting it into the notch 5 of the horizontal bar 1 constructed as described above at a predetermined position. However, in the assembled state, the wide surface contact between the flange 2 and reinforcing portion 3 of the horizontal bar 1 and the vertical bar 4 prevents displacement in the longitudinal direction of the horizontal bar 1, and the flange 1 of the horizontal bar 1 is prevented from shifting in the longitudinal direction. Also, due to the wide surface contact between the reinforcing portion 3 and the flanges 6, 6 of the vertical bar 4, displacement of the horizontal bar 1 in the width direction can be reliably prevented. Moreover, horizontal bar 1
The removal movement of the vertical beam 4 is strongly prevented by the engagement of the stepped portion a formed at the strong connection portion between the flange 2 and the reinforcing portion 3 with the retaining piece 7 formed on the flange 6 of the vertical beam 4. can be prevented.

In the above-described embodiment, the flange 2 and the reinforcing portion 3 are formed into a solid shape, but instead of this, they may be formed into a hollow shape as shown in FIG. 4.

Alternatively, as shown in FIG. 5, the stepped portion a for the retaining piece 7 of the vertical bar 4 may be formed only on one side of the portion of the horizontal bar 1 where the flange 2 and the reinforcing portion 3 are connected. good.

Furthermore, the retaining piece 7 may be constructed separately from the vertical beam 4.
