Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for connecting pillars made of hollow extruded metal members and bundle stones in an entrance porch.

[Conventional technology]

The conventional device for connecting a pillar to a bundle of stones, if the pillar is made of wood, is to drill a concave hole in the top surface of the bundle stone, provide a convex tenon at the bottom of the pillar, and connect the pillar by fitting the tenon into the hole. This is generally known, and when the pillar is an extruded metal member, a die-cast connecting fitting with a U-shaped cross section is generally fixed to the top surface of the bundled stones with the open opening facing upward. The lower ends of the pillars are fitted into the connecting fittings, and screws are screwed in from the outside of the connecting fittings to connect them.

[Problem that the invention attempts to solve]

In the above-mentioned conventional technology, it takes a lot of effort to drill holes in the pile stones and create tenons on the pillars, and it is especially impossible to make tenons with extruded hollow sections. According to the technology used,
Since the screw head was exposed on the outside, there was a drawback that it spoiled the appearance.

SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a device for connecting a bundle stone and a pillar, which does not require the provision of the above-mentioned tenon, can be firmly connected with a simple operation, and has a good appearance.

[Means for solving problems]

The device for connecting a bundle stone and a pillar according to the present invention has lip grooves protruding along the longitudinal direction on both opposing inner surfaces of a pillar made of an extruded hollow metal member, and a connecting plate is installed between the opposing lip grooves. , the end facing the lip groove is bent, and the bent part is fixed with a bolt protruding from the lip groove, and the bundled stones are attached from the back plate that is in contact with the lower surface of the bundled stones connected to the lower end of the column. A penetrating tight bolt is screwed into the connecting plate.

〔Example〕

FIG. 3 shows an example in which the pillars 3 supporting the roof 2 of the entrance porch 1 and the bundling stones 4 are connected by the connecting device according to the present invention. As shown in Figure 2, the pillar 3 is made of an extruded metal material, specifically an aluminum alloy, and has a hollow body with a rectangular cross section. 5 are opposed to each other and protrude over the entire length in the longitudinal direction.
A connecting plate 6 is fitted into the inner space on the lower end side of this column 3, and the connecting plate 6 is made by bending both ends of the plate body in the same direction so as to fit between both lip grooves 5, 5. It has been formed. The means for fixing the connecting plate 6 to the column 3 is to fit a bolt head 9 into each lip groove 5, project the bolt 8 into the inner space of the column 3, and bend the bolt 8 to the column 3. It is inserted into the bent part 7 and secured by tightening with a nut 10. Furthermore, a hole 11 is made in the center of the connecting plate 6,
A nut 12 is welded to its upper surface. However, the part of the connecting plate 6 having the extraction hole 11 in particular is formed thick, and the extraction hole 11 is provided with a female thread (not shown).
may also be engraved, in which case the nut 12 to be welded described above becomes unnecessary.

Next, the bundle stone 4 is made of a truncated quadrangular pyramid block body, and a through hole 13 is bored from the upper surface to the lower surface. The material is made of natural stone, artificial stone, or concrete, and the pillar 3 having the above-mentioned structure is erected on the upper surface of this bundle stone 4, and the back plate 14 in the form of a plate wider than the lower surface of the bundle stone 4 is installed on the lower surface of the bundle stone 4. A tight bolt 16 is passed through a hole 15 made in the center of the back plate 14 which abuts and also serves as an anchor for fixing the bundled stones, and is passed through the through hole 13 drilled in the bundled stones 4 to be fixed to the pillar 3. It is screwed into the nut 12 of the connecting plate 6.

As shown in FIG. 1, a guide block 17 that fits into the through hole 13 of the bundle stone 4 is protruded from the center of the back surface of the connecting plate 6, and the tip of the inserted tight bolt 16 is inserted into the connecting plate. A guide hole 18 is drilled to guide the hole 11 drilled in 6.

Therefore, when connecting the bundle stone 4 and the pillar 3, pass the bolt 8 through the bent part 7 of the connecting plate 6, temporarily tighten the nut 10 onto the bolt 8, and insert the bolt head 9 from the lower end of the pillar 3. into the lip groove 5 and connect the connecting plate 6 to the column 3.
The connecting plate 6 is set at the lower end opening and fixed by tightening the nut 10. Next, the back plate 14 is placed on the lower surface of the bundle stone 4, and the tight bolt 16 is inserted through the hole 15 thereof, and the through hole 13 of the bundle stone 4 is passed through. After this is erected on the entrance porch 1 as shown in FIG. 3, the bundle stones 4 are fixed with concrete.

[Effect of idea]

The device for connecting a bundle of stones and a column according to the present invention has a lip groove formed on the inner surface of the column made of an extruded hollow metal member, and a connecting plate is fixed with a bolt that protrudes from the lip groove, and the connecting plate is in contact with the lower surface of the bundle of stones. A tight bolt is inserted from the back plate through the bundled stones and screwed into the connecting plate,
The connecting plate is fixed inside the pillar by the lip groove, and the tight bolts pass through the holes drilled in the bundled stones, so the connecting means such as the connecting plate and tight bolts are not visible from the outside, and the appearance is improved. This will improve the condition. In addition, since the connecting plate is bolted into the lip groove, it is easy to install, eliminating the need for secondary processing such as notches on the column, and making it easy to connect the column and the bundled stones. Moreover, it can be connected firmly with tight bolts.
