Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prefabricated handrail used as a handrail installed on a balcony, veranda, etc., or as a protective fence installed on a rooftop, etc. A stopper is provided, and the post locking piece is fixed to the post, and the end of the seat board and the end of the upper horizontal beam of the baluster unit are tightened and fixed by the stopper, thereby connecting the cap and the support. The present invention relates to a connection structure for an assembled handrail that can reduce the number of parts of the connection structure between the cap and the handrail unit and between the cap and the handrail unit, and improve the workability of the connection.

The structure of the present invention will be explained with reference to the embodiments shown in the attached drawings.
A is a hollow cap, and the lower surface side thereof has inward protrusions 1, 1 protruding in directions facing each other, and an opening 2 between these inward protrusions 1, 1. is formed.

Reference numeral B denotes a pillar supporting the above-mentioned cap A, which is formed into a hollow cross-section with a road construction shape, and has vertical guide grooves 3, 3 on both sides thereof, and the lower end is used for mounting balconies, floors, etc. Base C
It is buried and firmly planted.

D is a balustrade unit disposed below the Kasagi between a pair of adjacent pillars B and B which are erected at an appropriate distance from each other, and a retaining wall 4 is vertically disposed on one side. an upper horizontal beam 5 formed in a cross-sectional shape, a lower horizontal beam 8 having a retaining wall 6 erected on one side and a retaining groove 1 provided on the lower surface;
It consists of a vertical member 9 whose both ends are fixed between the respective fastening walls 4 and 6 of the upper and lower horizontal bars 5 and 8 by means of welding, screwing, etc., and the vertical member 9 includes a plurality of pieces. Standing child 9a・
. . . In addition to using panel 9a, as shown in FIGS. 1 and 5, panel 9b made of asbestos slate, metal plate, etc. is used.

As shown in FIGS. 2 and 3, the connection between the Kasagi A and the support column B is achieved by a seat plate 11 having a substantially U-shaped cross section and having downward projecting pieces 1G and 10 along the longitudinal direction on both sides. From the opening 2 on the lower side of the Kasagi A, place the dial 11 diagonally, insert one downward protruding piece 10 into the inside of the Kasagi A, and then insert the other downward protruding piece 10 to remove the inward protruding piece. 1.1
A fastener 13 provided in advance on the seat plate 11 side connects the upper side 12a of the post locking piece 12, which is formed in a substantially U-shape, and the substantially center portion of the seat plate 11. Inward projecting piece 1, 1
The pair of leg pieces 12b, 12b hanging from both ends of the upper side 12a of the column locking piece 12 are inserted into the vertical guide grooves 3, 3 of this column B from the upper end of the column B. together,
Each leg piece 12b.

12b and the bottom wall of each vertical guide groove 3.3, the column locking piece 12 and the upper end of the column B are fixedly attached by a fastener 17 that passes through the bottom wall of each vertical guide groove 3.3.

In addition, the connection between Kasagi A and baluster unit) D is
As shown in FIGS.
This is done by tightening and fixing the inward protrusions 1, 1 of the Kasagi A with the fasteners 14 provided in advance on the sides, and in this case, the tip of the end of the upper horizontal bar 5 of the baluster unit (D) is attached to the support. It fits into the vertical guide groove 3 formed on the side surface of B.

Furthermore, as shown in FIGS. 4 and 6, the baluster unit D has one end of a connecting piece 15 formed of an angle piece or the like fitted into the locking groove 1 provided in the lower horizontal beam 8. By fitting the other end of the connecting piece 15 into the vertical guide groove 3 of the column B and fixing it to the bottom wall thereof, it is fixed to the side surface of the lower end of the column B.

Next, FIGS. 1 and 8 show a modification example in which expanded metal or a similar lattice-like body is used as the vertical member 9 of the baluster unit (D). are provided with a pair of protrusions 16° and 16 respectively to form the vertical guide groove 3.3.
The ends of the vertical members 9 are fitted into the vertical guide grooves 3 and fixed by fasteners 18.

As mentioned above, in the connection tank and structure of the assembled handrail according to the present invention, the seat plate 11 and the post locking piece 12 are provided on the cap A,
The column locking piece 12 is fixed to the column B to connect the cap A and the column B, and the end of the seat plate 11 and the baluster unit)
Since the cap A and the baluster unit D are connected by fastening to the end of the upper horizontal beam 5 of D, a plurality of fasteners are used.

Since the configuration is such that the handrail is assembled by integrally connecting the three parts of the cap A, the pillar B, and the handrail unit D with only one piece of the seat plate 11 and the supporting and locking piece 12, it is different from the conventional cap. Compare the assembly methods that require at least three connecting members, such as the pillar, the pillar and the baluster unit, and the baluster unit and the cap, and calculate the number of parts that connect or fix them. In addition, a pair of inward projecting pieces 1°1 are provided on the lower surface side of the cap A to form an opening 2 along its longitudinal direction, and between these inward projecting pieces 1, 1, the above-mentioned Since the seat plate 11 is straddled, there is no need to perform secondary processing such as drilling, bending, welding, etc. on the main components such as the capboard A. A prefabricated handrail can be manufactured at a lower cost.

In addition, between the seat plate 11 and the column locking piece 12 and between the seat plate 11 and the upper horizontal beam 5, the inward projecting pieces 1, 1 to the capacitor are held in place and tightened and fixed by the fasteners 13 and 14, respectively. Therefore, between Kasagi A and the post locking piece 12, and between Kasagi A and Honsuriko unit)
The strength of the bond with D is improved, and a strong connection can be achieved despite the reduction in the number of parts.

Furthermore, the middle and upper horizontal bars 5, 8 and the vertical members 9 are assembled in advance as a baluster unit D, and are suitable for standardization in factory production and on-site construction.

In addition, the upper and lower horizontal bars 5 can be installed without changing various parts for connecting and fixing the baluster unit D and the pillar B or the cap A.
, 8. One of the advantages of the present invention is that a handrail with a high design effect can be easily provided by variously changing the vertical members 9 provided in the vertical members 9.
