Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides mounting hardware having a cylindrical baluster receiving part into which the lower end of the baluster can be inserted and fixed, by arranging them in the longitudinal direction of the outer surface of the underfloor beam material and extending them to the side. This invention relates to a handrail device that can easily, quickly and accurately attach a baluster to an underfloor beam, thereby improving the construction efficiency of a handrail device for balconies, etc. and shortening the construction period.

Conventionally, a handrail device 1A for a balcony or the like has been formed by welding the lower end of the baluster a directly to the underfloor beam material and covering it with concrete C, as shown in FIG. It is difficult to maintain the balusters vertically and to make the heights of the top surfaces of each baluster the same, resulting in poor construction efficiency and cracks e due to stress concentration etc. at the contact area d between the baluster a and the concrete c. This caused problems such as water leakage and corrosion of the lower end of the baluster a due to rainwater penetrating.

The present invention aims to provide a handrail device that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

In FIGS. 1 and 2, a handrail device 1 of the present invention attaches a plurality of mounting brackets 4 having rectangular cylindrical handrail receivers 3 into which the lower ends of balusters 2 can be inserted and fixed to an underfloor beam. A handrail panel 7 that can be attached to the outer surface of the underfloor beam 5 in the longitudinal direction through a mounting piece 6 fixed to the underfloor beam 5, and a handrail panel 7 that can hide at least the outer surface of the underfloor beam 5 is inserted between the mounting brackets 4. And,
The baluster 2 has a prismatic shape and has a reduced portion 2a at its lower end.
At the same time, bolt holes 8 are formed in the reduced portion 2a to pass through both sides of the reduced portion 2a.

The mounting bracket 4 has the above-mentioned baluster receiving part 3 extending vertically at the tip of the base plate 4a, and the baluster receiving part 3 has an inner hole having the same external dimensions as the reduced part 2a at the lower end of the baluster 2 so that the reduced part 2a at the lower end of the baluster 2 can be inserted therein. It is formed into a rectangular cylindrical shape, and bolt holes 9 that can be aligned with the bolt holes 8 of the reduced portion 2a of the handrail 2 are bored on both sides.

The mounting bracket 4Q substrate 4a is a rectangular plate, and a bolt hole 10 is vertically provided at its rear end.

The underfloor beam material 5 has an H-shaped cross section, and inside the outer groove,
A bolt hole 1 that can match the bolt hole 10 of the substrate 4a
Mounting pieces 6 with holes 1 perforated therein are mounted between the upper and lower flanges 5a and 5b and at right angles to the web 5c at intervals of the length of the handrail panel 7 in the direction of the material axis.
Angle materials 13.13 for attaching the handrail panel 7 are attached to the upper and lower surfaces of the panels a and 5b, and the vertical pieces 13a are attached to the upper and lower flanges 5.
The handrail panels 7 are arranged to protrude from the edges of a and 5b, and the handrail panel 7 has a greater height than the underfloor beam 5.

By fixing the mounting bracket 4 to the mounting piece 6 using bolt holes 10, bolts 14 passing through the bolt holes 11, and nuts 15, the mounting brackets 4 can be placed side by side in the axial direction of the outer surface material of the underfloor beam 5 and protruded from the side. and by inserting the reduced part 2a of the baluster 2 into the baluster receiving part 3 and screwing it with the bolt 16 and nut 17 inserted through both the bolt holes 8 and 9,
Both balusters 2 are installed vertically, and the heights of their tip surfaces are the same.

Note that the handrail 18 and reinforcing material 19.20 are welded to each baluster 2 and connected to each other to improve the installation strength.
The handrail panel 7 is made of the vertical pieces 1 of the angle members 13, 13.
3a.

By screwing it to 13a, it can be inserted behind the baluster receiver 3 and between the base plates 4a, and can cover the outer surface of the underfloor beam 5.

Note that a decorative plate 21 such as a colored steel plate is attached between the reinforcing members 19 and 20.

22 is a floor panel placed on the underfloor beam material 5.

Note that the baluster 2 can be formed into various cross-sectional shapes such as a cylinder as well as a prismatic one, and the mounting bracket 4 can be directly attached to the underfloor beam material 5 by bending the rear end at a right angle without using the mounting piece 6.
It is also possible to fix it by screwing or the like.

As described above, the present invention has a structure in which the mounting brackets having a cylindrical baluster receiving part into which a handrail can be inserted and fixed are juxtaposed in the longitudinal direction of the outer surface of the underfloor beam material, and as a result, the lower end of the handrail By inserting and fixing the parts into the baluster receivers, the 9 handrails are fixed perpendicularly to the underfloor beam material, and at the same time, the height of each baluster can be made equal.The 9 handrails can be attached by conventional welding. By reducing the occurrence of distortion compared to the case where the handrails are arranged vertically and at equal intervals, it is possible to easily and quickly form a handrail device with balusters arranged vertically and at equal intervals, without requiring the operator's skill, and improving construction efficiency. In addition to shortening the first half of the construction period, the exterior appearance of the underfloor beams can be improved because the handrail panels hide the outer surfaces of the underfloor beams.

As shown in this example, when a decorative plate such as a colored steel plate is attached between the upper and lower reinforcing members of the baluster, the beauty of the handrail device can be further improved, and the windproof and sound insulation effects can be improved. 4. When fixing the baluster 2 and the like with loose bolts, the mounting position can be easily adjusted during fixation.

Furthermore, there is no need to cover the connecting portions of the underfloor beams with concrete, and therefore water leakage due to cracks in the concrete can be prevented.
