Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail supporting structure erected on a building, for example, a handrail provided on a rooftop, a veranda, a balcony, an outer corridor, an outer stairway, etc. of an apartment house. Available.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional handrail 61, which is erected on a rooftop 62 of a building. The roof sheet 63, which is a component of the building, has a waterproof sheet 6
The waterproof sheet 64 is formed on the roof surface 63 with an adhesive, and a parapet 65, which is a building frame projecting upward, is formed on the periphery of the roof 62. A drain 66 is provided further inside the building. The standing position of the handrail 61 is determined by considering the safety of a person using the handrail 61.
The roof surface 63 is an inner surface of the building, and the roof surface 63 is a railing upright surface. A concrete block 67 is installed on the waterproof sheet 64 at the location where the railing 61 is erected. Handrail 61 to 67
Is mounted on the lower end of the support 61A, and the handrail 6
The connecting tool 68, which is one of the basic fittings, is fixed to a concrete block 67 by a fastening tool 69 such as an anchor.

The concrete block 67 is fixed to the waterproof sheet 64 with an adhesive.

As another method of installing handrails, conventionally, a handrail is arranged on a waterproof sheet 64 on a roof surface 63, and a formwork is assembled below a support of the handrail. It has been practiced to pour a concrete slurry into the balustrade to fix the handrail column with a root-wound concrete.

[0005] In any of these handrail installation methods, when the handrail is erected on the roof surface 63 on which the waterproof sheet 64 forming the waterproof layer is laid, the anchor reaches the roof surface 63 through the waterproof sheet 64. No fasteners are used. The reason for this is to prevent the waterproof layer of the waterproof sheet 64 from being broken by fasteners such as anchors.

[0006]

For this reason, the conventional handrail is fixedly installed on the rooftop 62 by an adhesive or concrete weight, and the handrail is supported by the handrail supporting structure against a normal load applied to the handrail. Although sufficient, for example, when a strong wind of a typhoon acts on the handrail and the wind pressure becomes larger than expected, a new support structure that can increase the support strength of the handrail more than before is devised. Is required.

An object of the present invention is to increase the supporting strength of the handrail, not only when the fastener reaching the handrail standing surface is not used, but also when the fastener is used. It is an object of the present invention to provide a handrail support structure that can be used.

The present invention focuses on the fact that a cap is disposed on the upper surface of a building frame projecting upward like a parapet on the roof of a building for waterproofing purposes and appearance measures, and this cap is used effectively. Thus, the object of the present invention is achieved.

[0009]

SUMMARY OF THE INVENTION A handrail support structure according to the present invention comprises a handrail standing upright from a handrail standing surface, which is a constituent surface of a building, and a handrail separated from the handrail standing surface. It is configured to include a building frame projecting upward, a cap covered on the upper surface of the building frame, and a holding member erected between the cap and the handrail and supporting the handrail. It is characterized by the following.

According to the present invention, a stay member is erected between the handrail rising from the handrail standing surface and the capping tree covered on the upper surface of the building frame, and the handrail is supported by the stay member. The support strength of the handrail can be increased by the amount supported by the holding member.

[0011] In addition, since the cap is covered on the upper surface of the building for waterproofing and appearance measures, the supporting strength of the handrail can be effectively utilized by effectively using the cap which is originally required for the building. Can be improved.

In the present invention, the holding member may extend linearly and obliquely from the skirting to the handrail, may extend vertically upward from the skirting, and may extend horizontally from the tip to the handrail. Alternatively, a straight portion extending vertically upward, and a curved portion extending from the upper end of the straight portion to the handrail may be used, and the shape thereof can be arbitrarily determined in consideration of design and the like.

The stay member may be made of a single material, or may be formed by connecting a plurality of materials, and its structure and form are arbitrary.

The shed may be specially manufactured for connecting one end of a holding member that supports the handrail, and a stay member connecting member for connecting one end of the holding member to the upper surface of the shed. And a handrail coupling for coupling a handrail different from the handrail supported by the retaining member to the coping can be selectively attached. In place of the retaining member coupling, By attaching a handrail coupler, another handrail may be erected on the upper surface of the coping.

If the heddle is the latter, the heddle can be used both for attaching the staying member to the building frame and for attaching another handrail, so that the heddle can be shared. In addition to this, it is also possible to use a cap that was originally manufactured for attaching a handrail for attaching a stay member, and to achieve effective utilization of existing products.

[0016] The method of setting a sap on a building frame is, for example, as follows.
The bracket may be fixed to the building frame with a base member, and these brackets and the base member may be covered with a cap, and the cap may be engaged and connected to the bracket.
Alternatively, the mounting may be performed by directly fixing the cap to the building frame with a fastener such as a screw, and the installation structure is arbitrary.

In the case where the cap is installed on the building frame by the former method, the bracket and the base member which are arranged between the building frame and the cap and attach the cap to the building frame can be hidden by the cap. Appearance can be improved.

When the cap is installed on the building body in this manner, the connecting member for the holding member arranged on the upper surface of the cap to connect the holding member to the cap is provided with a stopper such as a screw only for the cap. It may be fastened with a garment, but it is more preferable to fasten to the base member with a garment penetrating the cap.

When the connecting member for the stay member is fastened to the base member by a fastening member penetrating the coping, the base member is directly fixed to the building frame. Thus, the effect of being able to be reliably attached to the building frame with great strength via the structure is obtained.

The fastening method of such a stay member connecting tool includes a case where the heddle is manufactured exclusively for connecting one end of the handrail supporting stay member as described above, and a case where the stay member is used. The present invention can be applied to both the case where the joint for handrail and the joint for handrail can be selectively attached to the upper surface of the coping.

In the latter of these, if the handrail coupling is fastened to the base member with a fastening tool penetrating the coping, the handrail coupling also has a large strength via the base member via the base member. And the same base member can be used for fastening the connecting member for the holding member and the connecting member for the handrail. Can be effectively utilized.

The above-described handrail support structure according to the present invention comprises:
It is applicable to both the case where the handrail is erected on the handrail erected surface where the waterproof layer is formed and the case where the handrail is erected on the handrail erected surface where the waterproof layer is not formed, Further, when the handrail is erected on the handrail standing surface on which the waterproof layer is formed, a fastening tool such as an anchor that penetrates the waterproof layer and reaches the handrail standing surface is not used, and the handrail is used. The handrail may be erected by using such a fastener.

The waterproof layer may be a waterproof sheet laid and fixed on the handrail standing surface with an adhesive or the like, or may be formed of mortar, and its material and material are arbitrary.

In the case where the handrail is erected on the handrail standing surface on which the waterproof layer is formed, a fastening tool such as an anchor which penetrates the waterproof layer and reaches the handrail standing surface is provided. In the case where the handrail is standing upright without being used, the handrail may be fixed to the handrail standing surface by a method using a concrete block or a root-wound concrete method.

One example of a standing location of the handrail supported by the support structure according to the present invention is a rooftop of a building, and another example is a veranda or a balcony. Further, the handrail support structure of the present invention can also be applied to handrails that are erected on the outer stairs or the outer corridor of an apartment house.

The upwardly projecting building frame on which the cap is covered on the upper surface may be a parapet or a waist wall.
