Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly structure such as a balcony provided to protrude from an outer wall of a building.

[0002]

2. Description of the Related Art Conventional balconies of this type have a joist supported by arms that project from the outer wall of a building, and a pillar that supports a handrail unit with a handrail at the upper end surrounding the balcony. It is general that the handrail unit placed on the column is fixed and assembled to the column.

[0003]

However, in the above-mentioned conventional structure, the pillars must be attached to a plurality of joists assembled at the construction site in advance before the handrail unit is attached, which is a high work. As a result, there is a problem that it is dangerous and the work efficiency is low.

The present invention is intended to solve such a problem, and it is an object of the present invention to eliminate the need to previously attach the pillars to a plurality of joists at a construction site and to improve the workability of assembling a balcony or the like. is there.

[0005]

SUMMARY OF THE INVENTION To solve this problem, the present invention provides a male screw shaft projecting downward of a handrail unit in a hole provided in a joist supported by an arm tree projecting from an outer wall of a building. The gist of the invention is to insert it and screw the nut from the lower end of the male screw shaft to tighten it.

With this construction, it is not necessary to previously attach the columns to a plurality of joists at the construction site, and the male screw shaft projecting downward of the handrail unit is inserted into the hole provided in the joist, and the nut is inserted from the lower end of the male screw shaft. By screwing and tightening, the workability of assembling balconies and window handrails can be greatly improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 6,
Numeral 1 is a joist supported to an arm 3 projecting from an outer wall 2 of the building, and the arm 3 is provided at a position to support both ends of the joist 1 in the lateral direction and a position to support a central portion in the lateral direction. The rear end of the joist 1 is fixed by a bolt 4 and a nut 5. By the way, the joists 1 are parallel to the outer wall 2 of the building and the crosspiece 6 located at the front end and also the outer wall 2 of the building.
A crosspiece 7 parallel to and located at the rear end, a crosspiece 8 that is at right angles to the outer wall 2 of the building and is located at both ends in the horizontal direction and at the center of the horizontal direction, and a crosspiece 8 that is also perpendicular to the outer wall 2 of the building. , 8 and the crosspiece 9 located between them. A C-shaped channel material is used for the crosspieces 6, 7, 9 and a plate material is used for the crosspiece 8, and the rear end portion of the crosspiece 8 projecting to the rear of the joist 1 is fixed to the arm 3. It is a thing.

Reference numeral 10 denotes a handrail unit which is placed and fixed on the joist 1, and the handrail unit 10 has a planar shape along the front end portion and both side portions of the balcony, and the handrail unit 10 is vertically moved at appropriate intervals in the length direction. In addition to the column cover 11 facing in the direction, the crosspieces 12 and 13 are provided at the upper and lower ends between the adjacent column covers 11 and 11, and the headstock 14 for handrails is provided at the upper end, and the inside of the balcony can be seen from the outside. The column cover 11 is provided with an outer wall member 15 for preventing
The state where the handrail unit 10 is placed and fixed on the joist 1 with the male screw shaft 17 protruding downward from the pillar cover 11 and inserted from the lower end of the 1 is provided with a decorative cover 19 fixed to the lower side of the horizontal rail 13 at the lower end so as to cover the joist 1 from the outside.

In order to mount and fix the handrail unit 10 having the above-mentioned structure on the joist 1, the crosspiece 6 located at the front end of the joist 1 has a hole 20 through which the male screw shaft 17 of the column 18 is vertically passed. The crosspieces 8 are formed at a plurality of positions, and the crosspieces 8 located at both ends in the lateral direction are provided with male screw shafts 17 of the columns 18 at positions near the rear end.
A support metal fitting 21 for forming a hole is formed on the inside and the outside by welding or the like. Two male screw shafts 17 project from the lower end of a column 18 placed near the rear end of the crosspiece 8 located at both ends in the horizontal direction, and holes formed by support metal fittings 21 inside and outside the crosspiece 8. 2 male screw shafts
17 is to be inserted.

The handrail unit 10 having the above structure is installed in the outer wall 2 of the building.
When the joist 1 supported by the arms 3 protruding from the joist 1 is placed and coupled, as described above, the male screw shaft 17 of the strut 18 is vertically penetrated through the hole 20 of the crosspiece 6 located at the front end of the joist 1. As described above, the decorative cover 19 on the lower side of the column 18 is placed on the crosspiece 6, and the nut 22 is screwed and tightened at the lower end of the male screw shaft 17 protruding from the hole 20, and the crosspiece 8 positioned at both ends in the lateral length direction is fixed. At the position near the rear end, the two male screw shafts 17 are vertically penetrated into the holes formed by the support fittings 21 inside and outside the crosspiece 8 so that the two male screw shafts 17 are vertically penetrated. The decorative cover 19 fixed by the stopper is placed on the crosspiece 8, the washer 23 is fitted to the lower ends of the two male screw shafts 17 protruding from the holes, and the washer 23 is applied to the lower surface of the crosspiece 8, and each male screw is attached. Mounting the handrail unit 10 on the joist 1 by tightening the nut 22 on the lower end of the shaft 17 It is those that are made.

Incidentally, although not shown in the drawings, a deck material is provided on the joist 1. Further, in the embodiment shown in the drawings, the decorative cover 19 is directly mounted on the crosspieces 6 and 8. However, the male screw shaft 17 is provided with a spacer that abuts against the inner surface of the upper end of the decorative cover 19, so that the handrail unit 10 can be installed. The height may be adjusted.

Further, in the embodiment shown in the drawings, the assembling of the balcony has been described, but the assembling of the window handrail for placing a flower pot or the like outside the window can be performed in substantially the same manner.

[0013]

As described above, according to the present invention, it is not necessary to previously attach the columns to a plurality of joists at the construction site, and the male screw shaft projecting downward of the handrail unit is inserted into the hole provided in the joists. By assembling and tightening the nut from the lower end of the male screw shaft, the workability of assembling the balcony or the window handrail can be greatly improved.
