Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail support structure for mounting a handrail support on the upper surface of a parapet in a handrail with a head provided on a rooftop parapet (support).

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of a handrail support of this type, for example, the structure described in Japanese Utility Model Laid-Open No. 5-3446 is known. The mounting structure of this handrail prop is a base member fixed to the parapet which is a support with anchor bolts,
It has a head tree placed on the base member in a state of being floated from the parapet, and a reinforcing member standing on the head tree by a long bolt extending from the base member, and a handrail prop is inserted so as to cover the reinforcing member. Moreover, the handrail post is attached to the parapet with the headstock by being screwed.

The base member is composed of a base plate and an arch-shaped head support bracket fixed to the upper surface of the base plate. The long bolt penetrates the reinforcing member, the head support and the head support bracket, and its lower end is It is screwed into a nut interposed in the gap between the base plate and the head bracket, and its upper end is screwed into a nut that abuts the reinforcing member. And
By strongly tightening the upper nut, the reinforcing member sandwiches the headstock and is fixed to the base member. in this case,
A seal member is interposed between the reinforcing member and the headstock to prevent rainwater from entering the inside of the headstock through a through hole for a long bolt formed in the headstock. As a result, corrosion of the base plate for supporting the handrail support columns to the parapet, the head bracket, etc. is prevented.

[0004]

In such a conventional mounting structure for a handrail post, since the seal member is constantly crushed by the reinforcing member, when the seal member is exposed to the outside air and deteriorates, it loses elasticity. When the handrail is leaned by a person leaning against the handrail and the handrail post is slightly tilted due to expansion and contraction in summer and winter, a gap is created between the reinforcing member and the headstock, and surface tension acts to prevent rainwater. There was a problem that the invades inside the Kasagi through the through hole.

An object of the present invention is to provide a mounting structure for a handrail support which can improve the sealing performance between the inside and the outside of a headstock.

[0006]

In order to achieve the above-mentioned object, the present invention provides a handrail support on a support with a headstock through a reinforcing member that penetrates the headboard mounted on the support and stands on the support. In the mounting structure of the handrail post for mounting, the board is mounted in a state of being lifted from the support, and a dish-shaped seal receiving member fitted to the reinforcing member is provided between the support and the board. The seal receiving member is characterized in that the sealing material is filled up to a position reaching the headstock.

In this case, while being fitted to the reinforcing member,
It is preferable to further provide a sealing member that covers the through opening for the reinforcing member of the headstock from above.

[0008]

According to the mounting structure of the handrail strut according to claim 1, a dish-shaped seal receiving member fitted to the reinforcing member is provided between the support and the head, and the head receiving member has the head receiving support. Since the sealing material is filled up to the position where the sealing material is filled up, the sealing material is in a state where the sealing material is in close contact (adhesion) from the peripheral surface of the reinforcing member to the inner surface of the reinforcing member, and the gap between the supporting member and the reinforcing member is watertightly closed. To do. In other words, it is possible to perform a wide area and a long distance inside and outside, and to seal between the inside and the outside of the head tree without applying a force from the outside to the sealing material.

Further, by providing a seal member which is fitted on the reinforcing member and covers the through-opening for the reinforcing member from above from the upper side, the gap between the reinforcing member and the reinforcing member is reduced.
The sealing member is watertightly closed from the lower side, and the sealing member is watertightly closed from the upper side. That is, the inside and the outside of the umbrella tree are doubly sealed.
