Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a balcony handrail, and more particularly to a fixing structure between a column and an upper chord that constitute a balcony handrail used in a balcony having an overhang in the center.

[Conventional technology and problems]

Balcony handrails are installed along the outer edge of a balcony to prevent people from falling off the balcony. Conventional balconies generally have a roughly rectangular shape that extends from the window openings of the building. Correspondingly, handrails were constructed by connecting them in a straight line or at right angles. However, in recent years, in order to increase the effective area of balconies or for design reasons, balconies with an overhang formed in the center have come into widespread use, and the handrails that are bent and connected at the overhang have become more and more popular. Demand is increasing. Conventionally, in order to form a handrail that connects upper and lower chord members at angles other than right angles, it has been done to manufacture supports or upper and lower chord members depending on the construction site and assemble them, but the manufacturing cost is high. This resulted in a problem of increased construction efficiency and poor construction efficiency. The present invention has been made to solve these problems, and an object of the present invention is to provide a fixing structure for a balcony handrail that can be manufactured at low cost.

[Means to solve the problem]

According to the present invention, the above object is achieved by attaching a reinforcing tube to the outer tube 10 having a rectangular cross section to approximately the middle portion thereof.
1 is formed by inserting the veranda 2 into the overhanging part 21
A hollow straight connecting column 1 stands upright at the center of the periphery, and two side walls 32 are reinforced by a reinforcing tube 31 and face each other at a supplementary angle to the bending angle at the bend of the overhang 21 of the veranda 2. 32; a handrail unit 4 comprising a plurality of handrails 43, 43... mounted between upper and lower chord members 41, 42; In the balcony handrail having a cap 6 that is attached by being locked to a locking protrusion 44, the connection and fixation of the straight section connecting strut 1 and the bent section strut 3 and the upper chord member 41 is carried out at the straight section. A substantially vertical fixing piece 51 that is inserted into the upper end side of the connecting column 1 and the bent section column 3 and fixed in contact with the inner wall thereof, and an end of the upper chord member 41 whose upper surface is a flat support surface 52a. This is achieved by providing a fixing structure for the balcony handrail, which is secured and fixed by a fixing piece 5 formed by a support piece 52 for placing and fixing the handrail.

[Effect]

As shown in FIG. 1, the overhanging portion 21 of the balcony 2
The joint portion 22 that connects the verandah base 20 with the verandah base 20 is often extended at a certain angle, for example, 135 degrees, and as a rule of thumb, this angle does not vary much from construction site to construction site. The present invention has been made with attention to these points, and can be used in various ways simply by selecting and using the bending section support 3 that corresponds to the angle of the joint section 22 between the veranda base 20 and the overhang section 21. It is designed so that it can be installed on the balcony 2 of the building.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 shows a balcony handrail installed using the fixing structure of the balcony handrail according to the present invention, and in the figure, 1 is a hollow linear part erected at the center of the overhanging part 21 of the balcony 2. The connecting column 3 is a hollow bent section column erected at a portion where the connecting section 22, the overhanging section 21, and the balcony base 20 meet. As shown in FIG. 2, the straight section connecting column 1 has the required strength by inserting a rectangular reinforcing tube 11 halfway into an outer tube 10 having a rectangular cross section. As shown in FIG. 2, the reinforcing tube 11 is erected on the floor surface of the balcony 2 by protruding the lower end thereof and joining it to the anchor 23. On the other hand, as shown in FIG.
The two side walls 32 and 3 that intersect at a complementary angle of 45° to the angle formed by the overhanging portion 21 and the joint portion 22 of 135°
A reinforcing tube (not shown) having a rectangular cross section is inserted halfway into the outer tube 30 having the veranda 2, which has a rectangular section 2, in the same manner as the straight section connecting column 1 described above.
will be installed on the floor. In FIG. 3, reference numeral 33 indicates a protrusion that projects from the inner wall of the outer cylinder 30 in order to accommodate the reinforcing cylinder inserted therein. As shown in FIGS. 3 and 4, the fixed piece 5 fixed to the upper ends of these columns 1 and 3 is a piece-like member made by cutting a long material with a substantially L-shaped cross section into a predetermined length. A vertical fixing piece 51 is formed with a screw hole 53 corresponding to the screw insertion hole 15, 35 drilled at the upper end of the pillars 1, 3, and a support piece 52 whose upper surface is a flat support surface 52a is formed. It is configured by forming a screw hole 54 corresponding to the screw insertion hole 45 of the baluster unit 4, and the fixing piece 51 is inserted into the upper end side of the column 3 and fixed with the screw 55 while in contact with the inner wall thereof. be done. As shown in FIGS. 1 to 3, the baluster unit 4 is formed by attaching a plurality of balusters 43, 43, . . . between the upper and lower chord members 41, 42, and the upper and lower chord members 4
1 and 42 are obtained by cutting a long piece of material formed to an appropriate length to match the upright pitch of the struts 1 and 3, and insert the end of the upper chord piece 41 into the supporting piece 52 of the fixed piece 5. It is mounted by fixing it with screws 56 while placed on the support surface 52a, and by fixing the lower chord member 42 to a bracket 46 fixed to the side walls 12, 32 of the columns 1, 3. Kasagi 6, as shown in FIGS. 3 and 4,
A locking horizontal piece 61 is formed longitudinally through the free end of the handle portion 60, which has a substantially inverted U-shaped cross section, and the locking horizontal piece 61 is formed on the upper surface of the upper chord member 41. After being locked to the locking pawl 47 of the locking protrusion 44, it can be connected to the upper chord member 41 using a screw 62. This Kasagi 6 is made of a long material that has been formed in advance by extrusion molding or the like.
It is used by cutting it to fit the vertical pitch of the caps 6, and its ends are cut at right angles or at 45 degrees, and if necessary, brackets are installed at the abutting connection parts of the caps 6. Cover is attached. Therefore, according to this embodiment, the balcony 2
After erecting the straight section connecting strut 1 at the center of the overhang section 21 formed in The fixing piece 51 of the fixing piece 5 is inserted into the upper end side, abuts against the inner wall thereof, and is fixed with screws 55, and the handrail unit 4, which has been adjusted to a predetermined length in advance, is connected via the pillars 1 and 3. Next, by capping and locking the cap 6 to the upper chord member 41 of the baluster unit 4, the balcony handrail is installed. In addition, when installing handrails on other balconies 2 of different sizes, it is sufficient to use a balustrade unit 4 whose longitudinal dimensions are adjusted according to the pitch of the pillars 1 and 3, and the joints of the veranda 2 By preparing several types of bent section supports 3 corresponding to the 22 projecting angles, it is possible to form handrails suitable for various types of balconies 2.

【Effect of the invention】

As is clear from the above description, in the balcony handrail according to the present invention, not only the connection and fixation with the top chord member between the straight part connecting posts, but also the connection and fixation with the top chord member between the straight part connecting post and the bent part support. The installation work is easy, and the strength of the connection and fixation can be increased, and handrails can be formed to accommodate balconies with various dimensions, improving versatility and reducing costs due to mass production effects. can be achieved.
