Description

[Detailed Description of the Invention] The present invention relates to a handrail mounting device that is installed on a so-called weir wall, such as the roof of a building, the surrounding wall of a balcony, or a standing wall constituting a fence.

Traditionally, general-purpose handrails are installed with concrete roots wrapped inside the weir walls that make up the surrounding walls of rooftops and balconies, which creates a dead space on the outside of the handrail, which increases the amount of space on the rooftop. This has the disadvantage that the usable space on the balcony or balcony is narrowed, and the surface where the handrail is installed has a base mortar layer,
Because surface coating layers such as a waterproofing layer and finishing mortar layer are formed, the binding force of the wrapped concrete does not directly reach the building frame.
The erection strength was insufficient.

This invention was made to eliminate the above-mentioned drawbacks of the conventional methods.By installing handrails upright on the weir walls, it eliminates the conventional dead space on rooftops and balconies, and maintains sufficient erection strength. It is an object of the present invention to provide a handrail mounting device that can facilitate installation work.

Hereinafter, the present invention will be explained based on illustrated embodiments.

The metal fittings 8 are connected and integrated, and this integrated anchor metal fitting 8 is fitted over the top of the weir wall 1. Thus, as shown in FIG. 5, a spacer 16 corresponding to the gap is inserted between the inner wall 8b and the indoor side surface of the weir wall 1, and a bolt insertion hole 1a (in the indoor/outdoor direction) bored in the weir wall 1 is inserted. 3), insert the anchor bolt 17a between the elongated holes 12, 12 on both side walls 8b, 8c of the anchor fitting 8, and tighten and fix it from both sides with nuts 17b, 17b. At this time, the height difference in the mounting position of the anchor bolt 17a is absorbed within the range of the elongated hole 12.

Next, the ends of the engagement pieces 11, 11 of the anchor fitting 8 are press-fitted to the bases of the ribs 2d, 2d of the weir wall cap 2 by utilizing the elasticity of the material, and the top plate portion 2a is attached to the top plate portion of the anchor fitting 8. By polymerizing on 8a, it is attached to the weir wall 1. Furthermore, a caulking material 19 is applied to the annular groove 18 formed between the outer circumference of the pillar 3, the inner circumference of the square hole 13 of the weir wall cap 2, and the top plate part 8a of the anchor fitting 8.
A decorative cap 7 is attached on top of the cap to seal the base of the support column 3 watertightly. On the other hand, a watertight material holder 20 having a substantially L-shaped cross section is fixed to each lower end of both hanging wall portions 2b and 2c of the weir wall cap 2 by screwing screws 21 into the groove 14, and a cross section of the tip of the holder 20 is approximately A watertight material 22 made of rubber or the like fitted to the U-shaped frame portion 20a provides a watertight seal between both hanging wall portions 2b, 2c and both side surfaces of the weir wall 1. 23 is a waterproof sheet pasted from the top surface of the weir wall 1 to the indoor side, and 24 is a finishing mortar layer provided on the indoor side of the weir wall 1. In addition, to connect the handrail cap 4 and the post 3, similarly to the lower end of the post 3, the bottom plate 4a of the handrail cap 4 is fixed to the upper end of the post 3 by screwing screws 15 into each bis pocket 3b, and then the bottom plate Upper plate 4b having a substantially U-shaped cross section at 4a
This is done by engaging the

FIG. 6 shows an anchor fitting 25 used when the weir wall 1 is made of reinforced concrete (RC).

Although various types of anchor fittings 8 and 25 have been illustrated, the structure of the anchor fittings and the method of fixing them to the weir wall 1 can be changed in various ways, and the weir wall 1 may be made of steel,
The present invention can also be applied to cases where the support is made of other materials such as wood or block, and furthermore, the support 3 may have a shape other than a square cylinder, such as a cylinder. On the other hand, it is desirable that at least three or more bis pockets 3a are provided on the inner surface of the support column 3 and are equally distributed in the circumferential direction.

As described above, according to the handrail mounting device according to the present invention, the handrail is installed directly on the weir wall, so there is no dead space on the outer periphery of the handrail as in the conventional case, and there is no dead space on the rooftop or on the roof. It is possible to maximize the usable space of the veranda, and since the installation of the weir wall cap and the erection of the handrail are done at the same time, the number of work steps is greatly reduced compared to the conventional method. Moreover, in the present invention, a plurality of bis pockets are formed along the longitudinal direction on the inner surface of the cylindrical support of the handrail, screw holes corresponding to the bis pockets are bored in the anchor fitting, and screws are screwed into the bis pockets through the screw holes. The anchor metal fittings are connected and integrated with the base of the support column by inserting the anchor metal fittings into the base of the support column, and this integrated anchor metal fitting is fixed to the top of the weir wall to erect the handrail, so the support strength of the base of the support support is large and it is easy to use the handrail. The entire sliding structure is firmly and stably erected on the weir wall, providing excellent safety. The member cost is reduced compared to connecting the handrail and the anchor fitting in the vertical direction using long and thick through bolts. Furthermore, since you only need to use one anchor fitting for each column,
It requires less effort to handle and assemble.
The handrail installation work becomes easier. Furthermore, this anchor fitting has the advantage of being extremely simple in structure and inexpensive to manufacture. Since there is no need for any connection fittings other than the anchor fittings, parts costs and installation labor can be reduced.
