Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for attaching handrail supports around balconies, rooftops, etc., stairs, hallways, etc.

[Conventional technology]

Handrails installed around balconies, rooftops, etc. are installed by relying on multiple handrail supports that are fixed upright to one part of the building. Various devices have been proposed and used.

These handrail support installation devices can be roughly divided into 1
There is a method of fixing one anchor bolt of the same length as the handrail support on the body, and using this anchor bolt to fix the handrail support as one body, and fixing a steel plate called a base plate on the body. At the same time, a relatively short anchor bolt fixed upright on this base plate,
After fixing a short post called a core metal whose outer periphery touches the inner periphery of the handrail post and fitting the handrail post onto the core metal, use screws from the outside of the handrail post to attach the handrail post. There is a method of holding the handrail support on the frame by fixing it to the core metal.

[Problem to be solved by the invention]

Among these known methods of installing handrail supports, the method of using long anchor bolts has a relatively simple installation device, but since it relies on a single anchor bolt, the installation may cause looseness during subsequent use. It is easy to use, but there are problems in terms of strength.

On the other hand, with the method of using a cored metal, although it is possible to fix the handrail support to a single piece relatively firmly, the mounting device is complicated and takes time to install, and the installation position of the cored metal needs to be adjusted. This was difficult, and there were many problems during construction, such as the fact that if there was even a slight misalignment, it would be impossible to fit and fix the handrail support to the core metal.

In view of the current situation, the present invention provides a handrail support that can be installed accurately and easily by easily absorbing some errors without requiring very strict precision of the parts that make up the handrail support. The purpose is to provide a device.

[Means to solve the problem]

In order to achieve the above object, the handrail post mounting device of the present invention includes a handrail post that is hollow inside, an anchor bolt for vertically fixing the handrail post, and a handrail post that is attached at the center of the bottom. A plurality of positioning protrusions are provided on the peripheral edge of the elliptical long hole formed in the hole, a drainage hole is formed by cutting out the connection between the side wall and the bottom, and the lower end of the handrail support is provided on the bottom. a dish-shaped base plate that holds the base plate, and an elliptical pipe member with an inner diameter that matches the long hole of the base plate. The hollow protrusion is integrally formed so that each arcuate surface can come into contact with the inner circumferential wall of the handrail support and that each arcuate surface is located on the same circumference centered on the center of the knob member. The present invention is characterized in that it is comprised of a core metal member made of a deformed tube having a cross section and a cross section, and a nand that is threadedly engaged with the anchor bolt.

[For production]

In the handrail support installation device of the present invention, an anchor bolt of a predetermined length is vertically erected by an appropriate means on a horizontal body for attaching a handrail, and the anchor bolt protruding from the body is Loosely fit the base plate and then the core metal member through a waterproof rubber sheet, and while the lower end of the core metal member is held in the base plate, attach the washer to the anchor bolt protruding from the upper end surface of the core metal member. A nut is screwed together through the base plate, and by tightening the nut, the base plate and the core metal member are securely fixed as one body.

At that time, the four hollow protrusions formed in the core metal member and the long hole in the base plate are formed by aligning and abutting the elliptical long hole formed in the base plate and the ellipse of the core metal member. The positioning protrusion provided on the periphery of the anchor engages with the positioning protrusion to prevent unnecessary rotation of the core member when the nut is screwed into the anchor bolt, but the engagement between the protrusion and the positioning protrusion is Since it is in a loosely fitted state, the core member can be moved slightly in the front, rear, left, right, and circumferential directions on the base plate, thereby making it possible to perform slight position adjustments.

The handrail support is fitted onto the core metal member thus fixed, the base end of the handrail support is positioned on the top surface of the inner bottom of the four peripheral walls of the base plate, and the handrail support is screwed to the core metal member. However, the core metal member has a hollow protrusion with an arcuate surface at the tip along the axial direction on the opposite outer periphery of the long axis and short axis sides of the elliptical pipe member.
Since all of the shaped surfaces are located on the same circumference drawn around the center of the pipe member, the handrail support strut that is fitted onto the cored metal member has an inner wall that lies on the same arc-shaped surface of the cored metal member. The contact point is flexible enough to allow for some degree of rotation.

Therefore, even if the core member is fixed with some rotation due to tightening of the NAND, the handrail support can always be fixed in the correct position.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the handrail support mounting device of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, the handrail support installation device of the present invention basically consists of an anchor bolt 2 having an appropriate length, which is vertically installed on a frame 1 to which a handrail (not shown) is attached. It is composed of a base plate 5, a core member 9, a napht 11, and a handrail support post 12.

Anchor bolts 2 are installed vertically on the body 1 by drilling a hole of an appropriate diameter in the body 1 with a drill or the like, inserting a chemical anchor into this hole, and then inserting and fixing the base end of the anchor bolt 2 into the chemical anchor. Alternatively, it is also possible to drive a grip anchor into the hole and insert and fix the proximal end of the anchor bolt 2 into the grip anchor, thereby ensuring that the anchor bolt 2 is vertically installed on the integral 1. If possible, the method of vertical installation is not particularly limited.

The base plate 5 includes a handrail support 12 that is not to be used.
A low-height side wall 5b is provided along the periphery of the bottom plate 5a, which has the same outer shape as the bottom plate 5a.
An elliptical elongated hole 6 for inserting the anchor bolt 2 is provided in the center of the side wall 5b and the bottom plate 5a.
A drainage hole 7 is formed by providing a notch in each continuous portion of the elongated hole 6 so that rainwater, etc. that has flowed along the inside of the peripheral wall will not accumulate in the base plate 5, and a drainage hole 7 is formed in the peripheral portion of the elongated hole 6. A total of four positioning protrusions 8, which also serve as a rotation stopper, are integrally protruded and provided on the long axis and short axis sides, respectively, facing each other.

As shown in FIG. 3, the core metal member 9 has an elliptical pipe member 9a having an inner diameter that matches the elliptical elongated hole 6 formed in the bottom plate 5a of the base plate 5, and has opposing long and short axes. An arcuate surface 9b is formed at the tip along the axial direction on the outer periphery.
A hollow protruding portion 9C is drawn with each of the arcuate surfaces 9b centered on the center O of the pipe member 9a (an irregularly shaped pipe whose cross section is cross-shaped, with the arcuate surfaces 9b being located on the same circumference C). This is what was done.

The handrail support column 12 is made of a hollow rectangular pipe member with a closed upper end, and can be held on the bottom plate 5a with its outer peripheral portion in contact with the side wall 5b of the base plate 5.
Moreover, the inner wall surface is large enough to make point contact with the arcuate surface 9C at the tip of each protrusion 9C of the core metal member 9; A contactable round pipe member can also be used as a handrail support. In that case, the bottom plate of the base plate 5 naturally becomes disc-shaped.

In addition, 3 in the figure is a rubber sheet formed in the same shape as the bottom plate 5a of the base plate 5, and an elliptical long hole 4 for inserting the anchor bolt 2 is provided in the center part.

Further, 10 is a washer that engages with the anchor bolt 2;
Reference numeral 1 indicates a nut screwed into the anchor bolt 2, and reference numeral 13 indicates a screw for fixing the handrail support 12 and the core member 9.

Hereinafter, a method of fixing the handrail support 12 on the body 1 using the members having the above structure will be described.

First, an anchor bolt 2 is vertically fixed on the body 1 on which the handrail is to be attached, by appropriate means, and then a rubber sheet 3 and a base plate 5 are fitted onto the anchor bolt 2 as shown in FIG. Adjust the mounting position of the base plate 5 using the long holes 4.6.

Next, with the elliptical pipe member 9a aligned with the elliptical elongated hole 6 of the base plate 5, the core member 9 is fitted around the anchor bolt 2, and its base end is brought into contact with the bottom plate 5a of the base plate 5. Then, the elongated hole 6 formed in the bottom plate 5a
The protrusions 8 formed on the periphery of the pipe member engage with the protrusions 9b provided in a cross shape on the outer periphery of the pipe member, thereby preventing the core member 9 from rotating unnecessarily in the circumferential direction. However, long hole 6
As shown in FIG.
The protrusions 8 provided on the peripheral edge of the long axis side are long in the arc (horizontal) direction, and the protrusions 8 provided on the short axis side are provided so as to be long in the vertical direction. The fixed position can be adjusted by slightly moving 9 back and forth, left and right, and circumferentially.

When the core metal member 9 is externally fitted onto the anchor bolt 2 in this manner, the tip of the anchor bolt 2 protrudes from the upper end surface of the core metal member 9, so the washer 10 is externally fitted onto the protruding tip of the anchor bolt 2. , when the nuts 11 are screwed together and tightened, the tightening force of the nuts 11 causes the rubber sheet 3,
The base plate 5 and the core metal member 9 can be pressed onto the frame 1 and fixed.

At this time, the core member 9 tries to rotate in the tightening direction by tightening the nut 11, but since its position is regulated by the projection 8, there is no unnecessary rotation.

When the fixation of the core metal member 9 onto the body 1 is completed, the lower end opening of the handrail support column 12 is fitted onto the core metal member 9, and the outer peripheral surface of the tip is attached to the inner peripheral surface of the side wall 5b of the base plate 5. Then, screw the screw 13 from the outer periphery of the handrail support column 12 and engage the tip with the protrusion 9b of the cored metal member 9 to attach the raincoat. It is fixed integrally.

Note that the inner circumferential wall of the handrail support column 12 is in contact with the cross-shaped protrusion 9C of the core member 9, but each protrusion 9C
The part of the handrail support column 12 in contact with the inner peripheral wall has an arc shape 9b.
Since the handrail support column 12 is formed in a point-contact manner, it is easy to fit the handrail support post 12 onto the core metal member 9, and even if there is some misalignment, the two can be smoothly engaged.

[Effects of the Invention] The handrail support mounting device of the present invention fixes the handrail support onto a single body using extremely few parts such as an anchor bolt, a base plate, a core member, and a nut, so it is easy to install a handrail. The work can be done extremely simply and easily, and the time required for constructing the handrail can be significantly shortened.

In addition, in this invention, the position of the base plate provided on the frame can be adjusted within a predetermined range with respect to one body, and the core member provided within the base plate can also be adjusted from front to back,
Since the position can be adjusted within a predetermined range in the left-right and circumferential directions, there is no need to go back and adjust the mounting position like with many handrail support installation devices, and the handrail Since the tip surfaces of the protruding parts of the core metal member that are in contact with the inner circumferential wall of the support column are all located on the same circumference, even if the external fitting position of the handrail support support to the core metal member is slightly different, the contact points between the two will remain the same. This has the advantage that the two can be easily engaged by slightly rotating in the circumferential direction for point contact.
