Description

[Detailed description of the invention] (Field of industrial application) This invention is a method for connecting horizontal members such as caps and horizontal frames to vertical members such as braces and supports in handrails installed on balconies, balconies, rooftops, etc. Regarding the device, more specifically, it is a connecting device for connecting a cylindrical horizontal member which is divided into an upper mold member and a lower mold member and are separably engaged with each other, and a cylindrical vertical member having a smaller diameter than the horizontal member. Regarding.

(Prior art and its problems) Conventionally, when connecting a handrail cap and a post, the upper end surface of the post is cut into a curved surface corresponding to the outer surface of the cap that has a circular cross section. At the same time, while the long bolt for tightening the support installed on the base is inserted into the support, the upper end of the bolt is inserted through the bolt hole provided in the support. The cap was protruded, and a nut was screwed into the protruding end from the inside of the cap and tightened, thereby connecting the cap and the support. (performed with the device removed). However, with this method, there were problems in that it took time and effort to grind the curved surface of the end face of the support, and the material cost was high because the bolt for tightening was long.

(Technical means for solving the problem) The present invention solves the above problems, and the technical means for this purpose is to provide a horizontal support plate 8 extending inside the horizontal member 1 over its entire length. The edges of both sides of the horizontal support plate 8 are fixed to one of the upper and lower mold members 1b, and an opening 13 having a shape corresponding to the cross-sectional shape of the vertical member 4 is provided in either the upper or lower mold member 1b. On the other hand, inside the vertical member 4, a bis pocket 12 is provided over the entire length, and the end of the vertical member 4 is inserted through the opening 13 of the horizontal member 1, and its tip is inserted into the horizontal support plate 8. It is characterized in that it is abutted and supported, and screws 14 are screwed into the screw pockets 12 of the vertical member 4 from the horizontal support plate 8 and tightened.

(Example) An example of the present invention will be described below with reference to the drawings.

Figure 1 shows the handrails installed on the weir wall S of the balcony.
are a cap and a lower horizontal frame as horizontal members, and 3 and 4 are a support and a brace, respectively, as vertical members.

The cap 1 and the lower horizontal frame 2 are each formed into a cylindrical shape by extruded aluminum. As is clear from Fig. 2, Kasagi 1 has an upper mold material 1a and a lower mold material 1b.
The engaging convex portion 5b of the lower mold material 1b is located in the engaging concave portion 5a of the upper mold material 1a, and the engaging convex portion 6a of the upper mold material 1a is located in the engaging concave portion 6b of the lower mold material 1b.
are removably engaged with each other, whereby the upper mold member 1a and the lower mold member 1b are separably engaged with each other. On the inside of the upper part of the lower mold material 1b, a pair of engaging grooves 7, 7 are provided on both sides facing each other over the entire length of the lower mold material. Both side edges of a band-shaped horizontal support plate 8 arranged to extend over the entire length of the cap 1 are engaged. Similarly, the lower horizontal frame 2 is divided into an upper mold member 2a and a lower mold member 2b.
By removably engaging the engaging protrusion 9a of the upper mold member 2a with the engaging recess 9b of the upper mold member 2a, the upper mold member 2a and the lower mold member 2b are removably engaged with each other, and the upper mold member 2a A pair of engaging recessed grooves 10, 10 are provided on both sides facing each other over the entire length on the inside of the lower part of the lower horizontal frame 2. Both side edges of the strip-shaped horizontal support plate 11 arranged as shown in FIG. Furthermore, the stand 4 and the support 3 are each cylindrical made of extruded aluminum, and the stand 4 has a third
As shown in the figure, a single bis pocket 12 extending along its central axis is integrally formed over its entire length, and although not shown, the column 3 has a plurality of bis pockets extending circumferentially along its inner surface. They are provided at intervals.

Now, FIG. 2 shows a connection device between the cap 1 and the stand 4, and a connection device between the lower horizontal frame 2 and the stand 4. First, when connecting the cap 1 and the stand, a circular opening 13 with an inner diameter that is the same as or slightly larger than the outer diameter of the stand 4 is provided in the center of the lower frame 1b in the width direction at a required location. , and then connect the upper end of the brace 4 to this opening 1.
3 into the interior so that the tip surface of the stand 4 is brought into contact with and supported by the lower surface of the horizontal support wall 8, and then a screw is inserted through a screw insertion hole (not shown) provided at the center of the horizontal support wall 8 in the width direction. 14 is screwed into the bis pocket 12 of the stand 4 and tightened, thereby integrally connecting and fixing the stand 4 to the cap 1 at right angles.

In addition, when connecting the lower horizontal frame 2 and the braces 4, the braces 4 are attached to the required parts of the upper frame member 2a of the lower horizontal frame 2.
The lower end of the brace 4 is inserted through the opening 15, and the lower end surface of the brace 4 is supported in contact with the upper surface of the horizontal support wall 11. The screw 16 may be screwed into the screw pocket 12 of the stand 4 through a screw insertion hole (not shown) provided in the support wall 11 and tightened.

In the operation of the above-mentioned connecting device, the upper part 1a of the Kasagi 1 and the lower part 2b of the lower horizontal frame 2 are first removed, and after the screws 14 and 16 have been tightened, they are attached to the other part 1b or 2a, respectively. Make sure that it is engaged.

FIGS. 4 and 5 show other embodiments of the connecting device between the cap 1 and the stand 4. FIG. In these embodiments, the upper part 1a and the lower part 1b constituting the cap 1 are separably engaged with each other by the same structure as shown in FIG.

First, in the connecting device shown in FIG.
7 are protruded oppositely over the entire length of Kasagi 1,
Both side edges of the band-shaped horizontal support plate 18 are placed on these horizontal support walls 17, 17 and fixed with screws 19, and then inserted through the opening 13 of the lower mold member 1b so that the tip surface is on the lower surface of the horizontal support plate 18. A screw 14 is screwed into the stand 4 which is abutted and supported. The connecting device shown in FIG. 5 is almost the same as the connecting device shown in FIG.
The difference from the case shown in FIG. 4 is that both side edges of the holder are fixed with a suitable adhesive (not shown).

In the above embodiment, the Kasagi 1, the lower horizontal frame 2, and the braces 4
Although only the connection device between the capacitor 1 and the support 3 has been described, the connection between the cap 1 and the support 3 is also the same as in this embodiment.

(Effect of the invention) According to the connecting device of the invention, it is necessary to provide an opening in the horizontal member for inserting the end of the vertical member and to attach a horizontal support plate. The installation work is much easier than the work of cutting the end of the vertical member into a curved surface like in conventional equipment, so the connection work is made that much easier.
Further, unlike conventional devices, there is no need for long bolts corresponding to the length of the vertical members, and short screws can be used, resulting in a significant reduction in cost. Further, according to the device of the present invention, the distal end surface of the vertical member is supported in contact with the lower surface or upper surface of the horizontal support plate of the horizontal member, and at the same time, the outer circumferential surface of the distal end of the vertical member is supported by the opening of the horizontal member. Therefore, the vertical member can be more stably supported with respect to the horizontal member, and both members can be firmly connected.
