DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a directly attached handrail support bracket used for installing handrails on a veranda, a corridor, a rooftop parapet, or the like.

[0002]

2. Description of the Related Art In order to install this type of handrail, generally, the lower end of the handrail post is directly embedded and fixed in the concrete frame, or a handrail post bracket for direct attachment is used, and this is mounted and fixed on the upper surface of the concrete frame. This is performed by inserting and fixing the lower end of the handrail support into the handrail support insertion portion.

[0003]

However, when the lower end of the handrail post is directly embedded in and fixed to the concrete frame, deformation of the handrail due to the difference in the coefficient of thermal expansion between the concrete frame and the aluminum of the handrail material, and the handrail post will not work. Problems such as alkali corrosion may be caused. On the other hand, if a handrail support bracket is used, such problems can be solved. It often happens that you cannot do this.

That is, when a handrail support bracket is used, it is indispensable that the concrete skeleton has the same height, the same horizontal or inclined surface in the longitudinal direction. Therefore, it is often wavy, uneven in the cross direction, and the angle of inclination is different in the longitudinal direction, and it is necessary to repair the handrail. In many buildings, the beams fall down due to the structural load over many months, and the undulation of the concrete frame is often further promoted. Because of the presence of gravel in the skeleton, it is often impossible to use it and it is necessary to change its fixing position. With bracket, concrete skeleton longitudinally handrail strut bracket height, position,
The orientation of the handrail support insertion section becomes uneven in various sections, and it becomes impossible to insert and fix the handrail support that is vertically and integrally formed in the longitudinal direction of the concrete frame.

[0005] The concrete body has the same height in the longitudinal direction,
Since it is rare to form the same horizontal or inclined surface, in most cases, even in the case of the above problems, it is a fact that the handrail is installed by embedding and fixing the lower end of the handrail support. On the other hand, in order to use the handrail support bracket, it is necessary to repair the concrete mortar.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a directly attached handrail support bracket capable of installing handrails regardless of the condition of a concrete frame.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention divides a handrail support bracket into a plurality of members, a direct mounting base mounted and fixed on the upper surface of a concrete frame, and a support fixing member fixedly disposed at the lower end of the handrail support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the drawings showing the embodiments. In FIGS. 1 to 6, A is a directly attached handrail support bracket, and B is, for example, a veranda, a rising wall in a corridor or a roof parapet. As described above, the concrete skeleton C serving as a base for installing the handrail is provided at a predetermined interval in an aluminum handrail (not shown) installed in the longitudinal direction of the concrete skeleton B, and in this example, a handrail support made of an aluminum hollow prismatic pipe. Are respectively shown.

The directly attached handrail bracket A includes a directly attached base 1 made of aluminum casting, which is mounted and fixed on the upper surface of the concrete frame B.
In this example, three members are divided into a pair of a pillar fixing member 20 made of an aluminum casting or an extruded aluminum material which is supported and fixed to the directly attached base 1 so that the height can be adjusted and the inclination can be adjusted. It is provided with.

In this embodiment, the directly-attached base 1 is integrally protruded from the directly-attached substrate 2 and the directly-attached substrate 2, and the handrail support insertion portion 8 is provided.
Are provided with a pair of opposed upright walls 7 which are divided into two facing surfaces, and the directly attached substrates 2 are respectively extended so as to protrude in the longitudinal direction of the concrete frame B in the non-opposite sides of the pair of upright walls 7 in this example. 50 which is preferable from 40 to 70 mm
a pair of elongated boards 9 each having a center-to-center spacing of 1 mm and having a long hole 10 extending in the width direction of the concrete skeleton B. 2 and the extension substrate 9 are provided with coating walls 12 and 13 having groove-shaped guide strips 14 facing each other and facing downward from the upper end on the opposite surface.

The directly attached substrate 2 is made of a thick wall having a lower surface inclined for a concrete frame B having an upper surface inclined, and a bolt hole 3 is provided at a position between the opposed covering walls 12.
And a pair of spaced upright bolts 4 standing upward from the bolt holes 3 are integrally planted.

At this time, the bolt head of the upright bolt 4 is fitted and fixed to the rear surface side so as to fit within the thickness of the directly mounted substrate 2 so as not to protrude from the rear surface of the directly mounted substrate 2. On the other hand, each of the upright bolts 4 is screwed with a clamping nut 5 formed by a pair of nuts each of which is vertically paired for receiving and tightening the bearing.

On the other hand, the strut fixing member 20 is a L-shaped strut having a thick overhanging substrate 21 and a strut-attached substrate 23, and having a thinner thickness below the strut-attached substrate 23. A piece 24 is integrally provided, and an elongated hole 24 for inserting the upright bolt 4 corresponding to the above-mentioned upright bolt position is formed in the overhang substrate 21 so as to be an elongated hole in the width direction of the concrete frame B in this example. The overhang substrate 21 is used for clamping and fixing by a clamping nut 5 screwed to the upright bolt 4.

In the directly attached handrail support bracket A of the present embodiment, the directly attached base 1 is arranged on the upper surface of the concrete frame B at predetermined intervals so that the upright bolts 4 are located at the widthwise ends. After making adjustments in the width direction as necessary, a concrete fixing bracket 11 such as driving a hole-in anchor from the upper surface of the concrete skeleton B through a pair of long holes 10 of the extension board 9 and attaching the hole-in anchor to the concrete skeleton B The supporting board 23 and the handrail support C are connected to the handrail support C through the through hole of the handrail support C so that the support locking piece 24 is hooked and locked at the lower end edge of the handrail support C while the mounting and fixing is performed. And a column fixing member 20 is fixedly disposed in a protruding manner at the lower end of the handrail column C, and the handrail column insertion portion 8 of the directly attached base 1 is partitioned by the other two opposing surfaces. So that the pair of opposing By interposing and interposing between the walls 7 and adjusting the position of the clamping nut 5 screwed on the upright bolt 4 of the directly attached base 1, the pair of interposed column fixing members 20 can be adjusted. The overhang substrate 21 may be used so as to be sandwiched and fixed so as to be horizontal.

At this time, the position of the pinch nut 5 can be adjusted vertically by its rotation, and the overhang substrate 21 has the elongated hole 22 for the upright bolt 4 to be inserted. If the positioning of the nut for receiving the bearing or its upper end is adjusted so as to be horizontal between the pair of upright bolts 4 and between the upright bolts 4 in the longitudinal direction of the concrete frame B, the nut is mounted and supported. The overhanging substrate 21 naturally becomes horizontal, whereby the handrail support C can be erected vertically at the same height at a predetermined position in the longitudinal direction of the concrete skeleton B.

That is, when the height of the directly attached base 1 placed and fixed on the concrete frame B is different in the longitudinal direction because the concrete frame B is wavy in the longitudinal direction, the inclination of the inclined surface of the concrete frame B is changed. In the case where the mounting angle of the directly mounted base 1 is also different due to the different angle, the overhang substrate 21 is also included, including the case where the directly mounted base 1 is shifted in the width direction so as to avoid the gravel position of the concrete frame B. However, the vertical fixing substrate 20 can also be used as a vertically movable inclined substrate whose position is variable with respect to the directly-attached base 1, and the height of the column fixing member 20 can be freely adjusted and the inclination can be adjusted with respect to the directly-attached base 1. It becomes possible to adjust the position inside.

In view of the part where the directly attached base 1 is placed and fixed, the undulation in the longitudinal direction of the concrete frame B is generally not so severe that the directly attached base 1 is inclined in the longitudinal direction of the concrete frame B. Therefore, the installation angle of the directly-attached base 1 caused by the waving can be almost ignored in most cases.
Therefore, it is sufficient to adjust the height in the longitudinal direction of the concrete body B against the waving, and therefore it can be said that, in general, the configuration of the present embodiment does not substantially hinder the installation of the handrail.

The directly attached handrail support bracket A of this embodiment is
Concrete fixing bracket 1 at a predetermined core-to-core spacing
Because a pair of long holes are provided for each one, the position of the concrete fixing bracket 11 is at two intermediate positions in the width direction of the concrete skeleton B, and the fixing strength of the directly attached base 1 is improved, and the strength against the handrail horizontal load is secured. At the same time, for example, the width of the concrete skeleton B is relatively small, which is effective in preventing the concrete skeleton B from being cracked or damaged due to the use of the concrete fixing bracket 11 at the width direction end.

In the figure, reference numeral 6 denotes a spring washer interposed between the clamping nut and the overhang substrate 21, and 30 and 31 end portions between the opposed covering walls 12 and 13 with respect to the groove-shaped guide strip 14. The ridge 32 is slide-fitted, and the locking ridge 33 at the lower end is

A small-sized cover made of an extruded aluminum material for preventing exposure of 11 and the like is a reinforcing plate of the handrail support C.

FIGS. 7 to 11 show other examples, in which the upright bolts 4 of the directly attached base 1 are arranged upright and below the bolt holes 3 of the directly attached substrate 2 with the bolt heads as necessary. The support column fixing member 20 is made of a single integrated aluminum casting or aluminum extruded material with respect to each of the directly attached bases 1 and a handrail. This is an example in which a single or a plurality of through bolts 29 is used as a fixture for fixing to the column C. In FIGS. 7 to 9, the direct-attached substrate 2 is configured horizontally for the concrete body B having a horizontal upper surface. The supporting column fixing member 20 is configured such that the handrail supporting column insertion portion 8 for receiving the lower end of the handrail supporting column C is integrally formed into a rectangular or rectangular shape on the other two surfaces, and the pair of overhanging substrates 21 and the supporting column also serve as reinforcement. Attached substrate 23
Are integrally connected by a side wall 25, and FIG.

It is constituted by.

The remaining basic configuration is basically the same as that of the above-described example.

Although the illustrated example is as described above, the number of the upstanding bolts is set to a large number of 3 to 3 or more, and a long hole corresponding to this is installed on the overhanging substrate.
Using a plurality of clamping nuts for fastening, for example, by using a plurality of clamping nuts to make up and down pairs of clamping nuts, if necessary, the direction of the long holes should be oriented in the longitudinal direction of the concrete frame, handrail support Is a hollow cylindrical pipe made of aluminum, and the shape of the column fixing member is adapted to this, including a direct mounting base, an upright bolt, a clamping nut, a handrail column, a column fixing member, an overhang substrate, a long hole. , And the specific materials of the opposing wall and handrail strut insertion part used as necessary,
