Description

TECHNICAL FIELD The present invention relates to a mounting structure for mounting beams to supports.

Conventionally, when installing a guard fence on a sidewalk or a road, a member is required to attach a beam member to a support post whose one end is buried in the ground. Since fences are installed not only on flat places but also on sloped places such as slopes and stairs, and on curved roads, there are various postures of the members that attach the posts and beams. Although it is possible to prepare different types of members depending on the installation form of the prevention fence, there is a risk of an increase in cost due to an increase in the number of parts and complicated management of parts. Therefore, a mounting bracket has been devised that allows adjustment of the mounting angle of the beam member with respect to the pillar by using a plurality of mounting brackets that are mutually adjustable in attitude (see Patent Document 1).

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and one of its exemplary purposes is to provide a new mounting structure capable of mounting columns, brackets, and beam members in a plurality of postures. .

In order to solve the above-described problems, a mounting structure according to one aspect of the present invention is a mounting structure for mounting a beam member on a support or a bracket, comprising: a holding member for holding the beam member; a support member configured to support. The support member is configured so that it can be fixed in a plurality of positions with respect to the strut or bracket without intervening the holding member.

According to this aspect, the pillars or brackets and the beam members can be attached in a plurality of postures, so that the same mounting structure can be used to install in various places regardless of the postures of the prevention fences and handrails.

A pair of holding members may be provided with the supporting member interposed therebetween. As a result, beams can be installed toward both sides from the pillars and brackets.

Both the holding member and the supporting member have circular outer peripheries, and may be linearly connected to the cylindrical beam member. As a result, it is possible to realize a design with a sense of unity in which the cross-sectional shape of the beam member and the mounting structure is substantially constant and the surface unevenness is small.

The holding member, the supporting member and the beam member may be arranged so as not to intersect with the strut. As a result, when the beam material is used as a handrail, even if the user moves while holding the handrail, the hand is less likely to interfere with the post.

The retaining member and support member may be casting parts manufactured in a mold. As a result, a rust-resistant member having a complicated shape can be realized at low cost.

The holding member has a spherical convex portion, one end face provided in a mortar shape, a disk portion provided with the convex portion on the end face, and a disk portion provided on the opposite side of the convex portion with the disk portion interposed therebetween. and a semi-cylindrical portion into which a cylindrical beam member is fitted. As a result, one end of the cylindrical beam member is closed by the disk portion, making it difficult for water and dust to enter the inside of the beam member.

The support member may be formed by fitting two semi-cylindrical parts of similar shape, and the semi-cylindrical part may have semi-spherical recesses in which the protrusions of the holding member are fitted at both ends. This makes it easier for the holding member to take various postures with respect to the support member.

It should be noted that any combination of the above-described components, and conversion of the expressions of the present invention between methods, devices, systems, etc. are also effective as aspects of the present invention.

The bolt hole 28 is a place through which the threaded portion of the bolt passes, and may or may not have a female thread formed on the inner periphery. If the bolt hole 28 is not formed with a female screw, a hole with a female screw formed may be formed in a part of the column 12 .

Half-dome-shaped connecting portions 30 are provided integrally with the body portion 26 on both sides of the body portion 26 of the second semi-cylindrical component 20b. Inside the connecting portion 30, a hemispherical concave portion 30a is formed in which a convex portion of the holding member 18, which will be described later, is fitted. On the side of the body portion 26 facing the first semi-cylindrical part 20a, there are a reference surface 32a that is the central cross section of the support member 20, a convex surface 32b that protrudes from the reference surface 32a, and a convex surface 32b that projects from the reference surface 32a. A recessed surface 32c and a recessed surface 32d further recessed than the recessed surface 32c are formed.

In the support member 20 according to the present embodiment, when the first semi-cylindrical part 20a and the second semi-cylindrical part 20b are combined, the convex surface 25b of the first semi-cylindrical part 20a is aligned with the second semi-cylindrical part 20b. , and the convex surface 32b of the second semi-cylindrical component 20b enters the concave surface 25c of the first semi-cylindrical component 20a, so that they are integrated at a predetermined position. As a result, the support member 20 becomes a member with a circular outer periphery. Also, in the supporting member 20, a triangular slit 34 is formed by the concave surface 25d of the first semi-cylindrical component 20a and the concave surface 32d of the second semi-cylindrical component 20b facing each other (see FIG. 2). The support member 20 may be configured to be attached to a support or bracket by partially inserting the support or bracket into the slit 34 .

Next, the holding member will be described in detail. FIG. 7(a) is a side view of the holding member according to the present embodiment, FIG. 7(b) is a view of the holding member shown in FIG. 7(a) viewed from direction A, and FIG. FIG. 7D is a view of the holding member shown in FIG. 7A viewed from direction B, and a view of the holding member shown in FIG. 7A viewed from direction C. FIG.
