Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used when erecting a handrail support post or the like on a parapet formed on the outer peripheral edge of a balcony, and the present invention is used to erect a handrail support post or the like on a parapet formed on the outer peripheral edge of a balcony, and the supported member such as the lower end of the support support member is This invention relates to an anchor for fixing a column, which is constructed by protruding from the back surface of a main body portion that is fixed to the upper surface thereof, an anchor leg portion that is embedded within the parapet.

[Conventional technology]

Generally, when using this type of anchor to erect a supported member such as a handrail post, the anchor must be attached to the parapet with sufficient strength to withstand the bending moment generated at its lower end due to the load applied to the supported member. Conventionally, in response to such a request, a plurality of anchor legs 2, 2, etc. have been protruded and sunk below the main body 1, as shown in FIG. are used.

[Problem that the invention seeks to solve]

However, such conventional devices are constructed with legs 2.2 protruding below the main body 1 in a complicated manner, resulting in a large overall volume, which makes it difficult to transport or store. They sometimes have the disadvantage of being bulky, or because of this, construction efficiency is reduced.

The present invention has been developed in response to these circumstances, and by reducing the overall volume, it is possible to reduce transportation or storage space, and to maintain the required installation strength even after installation. The purpose of the present invention is to provide an anchor for fixing a post.

[Means for solving problems]

In FIG. 1, the column fixing anchor according to the present invention is
It is shown correspondingly to its embodiment.

In this FIG. 1, l indicates a main body portion on which the supported member 3 is fixed and erected, and is buried within the parapet 4, and this main body portion I is firmly fixed on the parapet 4. The anchor legs 2 are disposed on the back surface of the main body l on two opposing outer tlltl edges 1a and la located along the longitudinal direction of the rosette 4.

[1] The load on the supported member 3 (force A in Figs. 1 and 15) generates a moment at its lower end, and in order to resist this moment, a force is applied to the joint between the anchor and the parapet 4. , a compressive force on the parapet 4 and a tensile force on the anchor leg 2 will occur.

In the conventional example, in order to maintain sufficient installation strength against this tensile force, the anchor leg portion 2 was buried deeply within the parapet 4.

On the other hand, since the above-mentioned tensile force is inversely proportional to the distance ML from the center of the supported member 3 to the anchor leg 2, this distance f
The larger iL is, the smaller the tensile force is, and the anchor leg 2
The reaction force applied to becomes smaller.

The present invention has been made with attention to this point, and by arranging the anchor leg portions 2 on two opposing outer edges located along the longitudinal direction of the parapet 4, the supported member 3 The distance f between the center of and the anchor leg 2
By making iL as long as possible and generating the drag force by the anchor leg 2 relatively efficiently, the anchor leg 2 is made to the minimum necessary size and its volume is reduced.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a state in which a handrail post, which is a supported member 3, is erected by the post fixing anchor according to the present invention, and FIG. 2 is a perspective view of the post fixing anchor according to this embodiment. It is shown.

In this embodiment, the main body l is formed into a flat plate shape from, for example, a copper plate, and has a supporting piece 5 welded to the upper surface of the main body l so that the supported member 3 can be welded and erected thereon. Its side edges are bent downward to form two anchor legs 2, 2 on each outer edge 1a, la.

In addition, in FIG. 2, 6 is a bend formed by bending the lower end of the anchor leg 2 inward in order to increase the hooking on the parapet 4 and further improve its installation strength. 7 shows a hole drilled in the main body part 1 for erecting a stud 8 to be described later, and 9 shows a separator guide hole used for installing an anchor using a separator. It is something.

Next, an example of the installation work of the anchor according to this embodiment will be explained based on FIG.
A stud 8 is erected on the main body l to which a polystyrene foam 12 is adhered to the upper surface, and an anchor with a mounting bar 13 attached to the upper end of the stud 8 is fixed to the formwork 11 by the stud 8 and nut 14 at the mounting bar 13. , concrete is poured into the space surrounded by this formwork 11 as shown by the broken line in FIG.
After that, the nut 14 is removed, the mounting bar 13 and the foamed polystyrene 12 are removed together with the formwork 11, and a mounting portion is formed on the parapet 4.

In this state, the main body part 1 of the anchor with the studs 8 erected on the top surface of the parapet 4 is exposed to the outside, so after cutting the studs 8, the top surface of the main body part 1 As shown in FIG. 4, the support piece 5
The supported member 3 can be easily erected by welding the support piece 5 to the lower end of the handrail post, which is the supported member 3, and filling this part with mortar or the like.

In addition, in FIG. 3, reference numeral 16 indicates reinforcement arranged within the space framed by the formwork 11.

In addition, although the most rational construction method when using the anchor of the present invention has been explained above, there are other methods that can be used for formwork 1.
It is also possible to fix the anchor by welding the main body part l to a separator which is disposed between the molds 11 and 11 and which holds the forms 11 and 11 at appropriate intervals. It is also possible to insert and fix the separator through the separator guide hole 9 of the main body part 1. In this case, welding work between the separator and the anchor is not necessary, and it is possible to improve the work efficiency.

In FIG. 5 a modification of the embodiment described above is shown.

This modification forms a plurality of anchor legs 2.2 on each outer edge 1a, 1a, and places these opposing anchor legs 2 in the gap between one of the anchor legs 2.2. The anchor is punched out using a progressive die (in this case, consideration is given to improving the material yield).

Further, FIGS. 6 to 11 show other modified examples. FIG. 6 shows the case where the anchor leg part 2 is formed separately and is welded to the main body part l, and FIG. 7 shows the above-mentioned modification. When the anchor leg part 2 in Fig. 6 is continuously formed to have a U-shaped cross section, Fig. 8 shows a side view (when the anchor leg part 2 in the shape of a letter is welded,
