Description

[Detailed description of the invention] [Field of industrial application] The invention relates to a handrail support mounting device for retrofitting a handrail support to a parapet (parapet) installed on the balcony of a concrete or wooden building. .

[Prior Art] Traditionally, parapets have been formed around the balconies of buildings, whether concrete or wooden, and when a handrail is later attached to the parapets, anchors are fixed to the parapets in advance. It is generally known that a handrail post is attached to this anchor.

However, since the top surface of a parapet usually has a water gradient that slopes inward, when installing handrail supports vertically, it is necessary to install anchors horizontally on the top surface of the parapet. After fitting a gasket between the lower side of the parapet and the anchor, the anchor can be fixed by sandwiching both sides of the parapet, a horizontal pedestal can be formed on the upper sloped surface, or the parapet can be used to compensate for the slope of the parapet. Anchors with legs are used to install the anchor horizontally.
Since the water gradient of a parapet varies, if a gasket or pedestal is used to attach the anchor, it must be prepared with a thickness that matches the water gradient, and must be prepared using different types of work and processes. In addition, when using anchors with legs, it is necessary to prepare legs with different heights depending on the water gradient. However, it is necessary to select the mounting member after considering the thickness of the parapet, and if the thickness exceeds the mounting limit, the handrail support cannot be attached.

[Problems to be solved by the invention] The present invention was devised in order to eliminate the drawbacks of the conventional technology in view of the above-mentioned actual situation. It is not only possible to easily erect handrail posts vertically on various parapets, but also to ensure the robustness of the handrail posts by improving the rigidity of the anchors themselves. An object of the present invention is to provide a mounting device for a handrail support on a balcony, which allows retrofitting of handrails to be carried out easily and improves work efficiency.

[Means for Solving the Problems] The technical means adopted by the present invention to solve the above problems is to install handrail support mounting tubes on both sides of the base plate, which has handrail support mounting tubes erected at right angles, in the longitudinal direction of the parapet. A support part that abuts the upper surface along the parapet, and a mounting surface that extends downward from the lower edge of the support part and has a length that contacts the side surface of the parapet are integrally provided, and the base plate and the mounting surface are integrally provided. In addition to forming an anchor by drilling a long hole through which a bolt fixed to the parapet is inserted, the long hole on the mounting surface is made vertically long, and the bolt that is inserted into the long hole in the base plate is provided with a fixing nut in addition to the fixing nut. The present invention is characterized in that the base plate is mounted and held horizontally by threading an adjustment nut.

[Operation of the invention] Therefore, according to the invention, the same anchor can be used horizontally to attach to various parapets with different wall thicknesses and upper water gradients,
Handrails can be easily and reliably retrofitted by horizontal adjustment using the space under the anchor.

[Example] The configuration of the present invention will be described in detail with reference to an example shown in the drawings.

In Figures 1 and 2, 1 is a concrete balcony, 2 is a parapet around the balcony, and 3 is a drainage ditch, and on the upper surface of the parapet 2, a water gradient is formed that slopes inward. At the same time, a handrail post 4 is erected on the parapet 2 via an anchor 5.

As shown in FIG. 3, the anchor 5 has a support portion 5b formed on one side edge of a base plate 5a that slightly projects downward, and a mounting surface 5c that extends downward at a right angle on the opposite edge. A handrail support mounting tube 6 into which the support support 4 is fitted is erected in a rectangular shape on the upper surface of the base plate 5a of the anchor 5.

Furthermore, on one side of the column 4, a long hole 7 is bored in the base plate 5a in the longitudinal direction of the parapet 2 to enable effective positioning of the handrail column 4, and a long hole 7 in the vertical direction is formed in the mounting surface 5c. A bolt anchor 10 vertically protruding from the upper surface of the parapet 2 and a bolt anchor 11 horizontally protruding from one side wall of the parapet 2 are inserted into the elongated holes 7 and 8, respectively. The anchor 5 is inserted through the parapet 2 and fixed to the parapet 2 using fixing nuts 12 and 13.

In the present invention, on the lower surface of the bolt anchor 10 than the anchor 5, and before the fixing nut 12,
An adjustment nut 14 for horizontally mounting the base plate 5a is screwed on. Note that 9 is a cap that is fixed to the upper end of the handrail support 4, and 15 is a fixing screw that fixes the handrail support 4 to the handrail support mounting tube 6.

In the configuration as described above, when attaching the handrail support 4 to the parapet 2 of the balcony 1,
First, bolt anchors 10 and 11 are driven into predetermined locations on the upper surface and inner surface of the parapet 2, respectively. Next, after screwing the adjusting nut 14 onto the vertical bolt anchor 10 driven into the upper surface, the anchor 5 is inserted into the elongated hole 7 and 8 into the bolt anchors 10 and 11. At this time, since the elongated hole 7 is drilled in the longitudinal direction of the parapet 2, the relative positions of the bolt anchors 10 and 11 in the longitudinal direction are adjusted, and the anchor 5 is installed accurately. 5b comes into contact with the upstream side of the slope of the upper surface of the parapet 2, and a space is formed on the lower surface of the base plate 5a by the support portion 5b. , while adjusting the vertical position of the elongated hole 8 relative to the bolt anchor 11 using the support portion 5b as a fulcrum, the base plate 5a of the anchor 5 is
can be made horizontal.

After that, the anchor 5 is fixed to the parapet 2 with fixing nuts 12 and 13, and the handrail post 4 is fitted vertically into the handrail post mounting tube 6 and fixed with the fixing screw 15, so that the handrail post 4 can be installed. This can be done easily and reliably.

Although this embodiment shows a configuration in which the anchor 5 is fixed to the parapet 2 via the bolt anchors 10 and 11, the structure is not limited to this, and as shown in FIG. 2'
When attaching the anchor 5 to the vehicle, coach bolts 10' and 11' may be used instead of the bolt anchors 10 and 11 for fixation.

[Effect of the invention] In short, the present invention has a base plate on which a handrail support mounting tube is erected at right angles, and on both side edges of the base plate, support portions that abut against the top surface along the longitudinal direction of the parapet, and the support portions. A mounting surface that extends downward from the lower edge of the parapet and has a length that touches the side surface of the parapet is integrally installed vertically, and a long hole is drilled in the base plate and the mounting surface, through which the bolt fixed to the parapet is inserted. At the same time, the long holes on the mounting surface are made vertically long, and the bolts that pass through the long holes on the base plate are fitted with adjustment nuts in addition to fixing nuts, so that the base plate can be held horizontally. Although it has an extremely simple installation structure consisting of an anchor made of a single member and a bolt anchor installed on the parapet, it is possible to use a type of anchor without being restricted by the thickness of the parapet or the water gradient. Not only can the handrail support be attached using the handrail support, but the basic structure is such that the base plate is installed and held horizontally, so the lower end of the handrail support can always be erected in a stable state on the base plate. . In addition, since the anchor is integrally formed, the rigidity of the anchor itself can be ensured on the two sides of the parapet, greatly improving the robustness of the handrail. Moreover, the bolts that fix the base plate can be tightened with the regular nuts. Since we have added an adjustment nut, we can use the operating space of the adjustment nut formed on the bottom side to adjust the elevation from the side.
By cooperating with the positioning of the vertical holes on the mounting surface, the handrail support can be easily moved vertically, and the workability of retrofitting the handrail support can be improved, making it extremely useful and practical. It is effective.
