Description

[Detailed description of the invention] (Field of industrial application) This invention is used to attach a handrail post to the top of a cap that protects the upper surface of the frame of a building such as a rooftop or balcony. This relates to the lower metal fitting.

(Prior art) A conventional lower metal fitting for attaching a handrail post to a Kasagi has bolts for fixing the handrail post bracket protruding upward from the top surface of the base frame which is fixed to the top surface of the structure with anchor bolts, etc. Yes, during construction, the position of the handrail post must be accurately marked on the top of the frame, the handrail post mounting bottom bracket must be fixed at the center of the handrail post, and then the cap wood is placed and the handrail post mounting bottom bracket is fixed. A hole was drilled at a position corresponding to the bolt of the metal fitting, and the bolt was made to protrude from the hole onto the top surface of the cap to attach the handrail post bracket.

(Problem that the invention aims to solve) However, when installing a handrail post using the lower metal fitting for installing a handrail post as described above, with a cap board placed on the top surface, drills must be made from the top surface of the cap board to correspond to the bolts. Because it is necessary to drill holes accurately,
It is necessary to accurately mark out the lower metal fittings for attaching the handrail post on the Kasagi, and this marking requires a lot of time, and even a slight center deviation between the bolt center and the drill hole is not allowed. However, if there was a slight deviation from the center, re-drilling the hole would make the top of the cap unsightly, and there were many problems such as rainwater entering and causing internal corrosion. Therefore, there has been a need for a lower metal fitting for attaching a handrail post to a capstone, which allows the handrail post to be quickly attached to the upper surface of the capstone without damaging the capstone.

(Means for solving the problem) The present invention has been made to solve the problems of the conventional technology, and is made by using a handrail post bracket 4 which is wider than the handrail bracket 4 and whose upper surface is an inclined surface corresponding to the cap 2. The handrail post mounting frame 5 has eaves pieces 8, 9 stretched through the legs on both sides of the handrail post mounting plate 7, and height adjustment screws 10 are threaded onto the eaves pieces 8, 9, and the handrail post mounting frame 5 is attached to the frame. The base frame 6 is provided with rising portions 12 and 13 at both ends of a mounting plate portion 11 which are in contact with the tips of the eaves pieces 8 and 9.

(Function) In this structure, the base frame 6 is fixed to the upper surface of the building frame 1 using anchor bolts or the like in correspondence with the handrail column mounting position, and the handrail column mounting frame 5 is placed on the upper surface of the base frame 6. eaves pieces 8 and 9 on both front and rear sides
After adjusting the height and inclination angle of the handrail post mounting plate 7 to match the cap 2 using the height adjustment screw 10 screwed into the base frame 6, which circumscribes both front and rear ends thereof.
Weld and fix to the rising portions 12 and 13 of. Next, place the Kasagi 2 on its upper surface, and then drill a hole from the top of the Kasagi 2 at the handrail post mounting position where the lower metal fitting for attaching the handrail post is fixed. Since a through hole is formed in the handrail post mounting plate 7 of the frame 5 at the same time, the handrail post bracket 4 can be attached to this through hole with a tap pin screw 14 or the like. Since the handrail post mounting plate 7 is formed wider than the handrail post bracket 4, there is no problem with this drilling even if there is a slight error in marking, and there is no problem in drilling the handrail post mounting plate 7 and the capboard 2. Since the holes are drilled at the same time, there is no center shift as in the conventional method, and the work of attaching the handrail post to the cap can be done quickly and accurately.

(Embodiments) Next, the present invention will be explained in more detail with reference to the illustrated embodiments. 1 is a building frame, 2 is a cap, 3 is a handrail column, and 4 is a handrail column bracket. The lower metal fitting for mounting a handrail post of the present invention is made by bending a steel plate approximately 2.5 mm thick, and is a base on which a mounting plate portion 11 is fixed to the top surface of the handrail post mounting frame 5 and the frame 1 with anchor bolts or the like. It consists of a frame 6. As shown in the figure, the handrail post mounting frame 5 is wider than the handrail post bracket 4 and has a handrail post mounting plate 7 with an inclined surface corresponding to the cap 2, and eaves pieces 8, 9 formed on both sides of the handrail post mounting plate 7.
A height adjustment screw 10 is screwed into each of two places. As will be described later, the handrail post mounting frame 5 is fixed to the base frame 6 by these eaves pieces 8 and 9, so the handrail post mounting plate 7 is positioned above the base frame 6 by ten to several tens of millimeters. It will be fixed at On the other hand, the base frame 6 has substantially vertical rising portions 1 at both front and rear ends that contact the tips of the eaves pieces 8 and 9.
2 and 13, and its width is preferably approximately equal to that of the handrail post attachment frame 5.
In addition, in the figure, 14 is a tuft pin screw for attaching the handrail post bracket 4 to the handrail post mounting frame 5, 15 is a fixing member for fixing the handrail post 3 to the handrail post bracket 4, and 16 is a fixing member for fixing the handrail post 3 to the fixing member. This is a fixing bolt. Therefore, the base frame 6 is fixed to the handrail post mounting frame position on the top surface of the frame 1, the handrail post mounting frame 5 is placed on the top surface, and the height and inclination angle of the handrail post mounting plate 7 are adjusted using the height adjustment screws 10. After adjusting, the eaves pieces 8 and 9 are attached to the rising parts 12 and 13 of the base frame 6.
By welding the cap 2 to the upper surface of the cap 2 and drilling a hole from the upper surface of the cap 2, a through hole is simultaneously formed in the cap 2 and the handrail post mounting frame 5 located on the lower surface of the cap 2. As described above, the handrail post 3 can be quickly and accurately attached by fixing the handrail post bracket 4 with the tatupin screws 14 or the like.

(Effects of the invention) As is clear from the above description, the present invention is equipped with a handrail post mounting frame that is wider than the handrail post bracket that is fixed to the rising part of the base frame by the eaves pieces on both sides. By placing a cap on the top surface and drilling a hole with a drill, it is possible to simultaneously form through holes in the cap and the handrail post mounting frame, which eliminates the problem of center deviation when drilling holes as in the conventional method. There is no need to worry about this, and since the handrail post mounting frame is wider than the handrail post bracket and has extra dimension, even if there is a slight error in the mounting position of the base frame on the frame, there will be no chance of drilling mistakes. There is no. Therefore, by using the lower metal fitting for attaching a handrail post of the present invention, it is possible to quickly and accurately attach the handrail post to the top of the cap, and the deformation of the upper surface of the frame can be absorbed by the height adjustment screw, resulting in a beautiful design. It is possible to obtain a finished product. Therefore, the present invention has extremely great practical value as it solves the problems of the conventional lower bracket for attaching a handrail post to a Kasagi.
