Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of standing a light metal handrail column in a case where a handrail is constructed on a veranda or the like of a concrete structure made of reinforcing steel or steel.

[0002]

2. Description of the Related Art A handrail is generally constructed by erectioning upper and lower furring strips between columns, arranging vertical bars between them, and arranging tops at the upper end. Assembling at a factory and standing columns on site. Is built by. However, since the erected portion is concrete and the stanchion cannot be erected as it is, conventionally, the stanchion base is pre-installed on the site.

The support base is a base support in which a base support is erected at the center of the seat plate, and the base plate is fixed to the installation surface by anchor bolts for its construction. To attach the columns to the base column, there are a method in which a collar is provided on both of them and bolting is performed, and a method in which a handrail column is inserted into the base column and is fixed with a set screw.

[0004]

According to the conventional method of erection of the handrail props as described above, if the base props are inclined due to an error in construction or the like, the handrail props may also be inclined. However, the state that a wide seat plate is fastened with anchor bolts is unnatural, and it is necessary to stand four anchor bolts in concrete to fix one seat plate, which is troublesome for construction. Workability was poor.

Even if the base column is tilted, if it is on the left and right, a correction is made in the construction of the handrail. on the other hand,
If there is a tilt in the front and back, the Kasagi will bend indefinitely instead of being lined up in series, so it is adjusted, but in the case of a parapet where the standing position rises to the edge of the veranda, tilt the upper surface inward. Since there are many cases, there is a problem that strength cannot be obtained especially when adjusting so as to eliminate the front-back inclination.

The present invention has been made in view of the above-described circumstances,
A handrail support column that can stand upright and maintain its state securely, and can improve the strength by injecting a curable viscous material. Moreover, the handrail support post can be constructed easily and the handrail can be constructed in a good appearance. The purpose was to provide a standing construction method.

[0007]

In order to achieve the above-mentioned object, the present invention provides an anchor bolt that is erected on a building frame through an angleable metal fitting and a support in order, and a supporter While adjusting the angle, bolt the nut at the lower end of the strut with a nut, and then fill the curable viscous material inside the angleable bracket and the lower end of the strut to make the angleable bracket and the strut against the anchor bolt. The vertical construction method of the handrail support columns was characterized by fixing the connection, the nut tightening, and the angle adjustment.

The angleable metal fitting is constructed as a set of a base on which a building body is placed and a container-shaped socket into which a support is inserted, and a curved convex surface which is arcuate in the front and rear direction is formed on the upper surface of the base. And a curved concave surface that slides with it, respectively, and a concave cutout and leg pieces are formed facing the bolt through hole as a wide space provided in the base, and a tight material is formed on each bottom surface of the base and socket. It is especially effective to achieve the purpose when the curable viscous material is injected into the bolt through hole of the base from the injection hole opened on the side of the socket in the state where the is there.

[0009]

[Operation] Since the construction method of the handrail support columns is configured as described above, only one anchor bolt needs to be installed upright on the concrete surface for one handrail support, which requires too much labor. It can be corrected by bending when constructing the handrail, even if it does not hang up and some inclination occurs. Further, when the standing surface is inclined like the upper surface of the parapet, it is possible to make a large correction by the angleable metal fittings placed on it.

Even if only one anchor bolt is used as described above, since the support pillar is bolted through the angleable metal fitting, the handrail can be stably supported, and the curable viscous adhesive is used. The upright state of the columns is fixed and maintained by the filling of the material.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings.

The procedure for vertically mounting the assembled pillar 1 of the handrail P on the parapet 3 is to set the anchor bolt 5 on the parapet 3 and pass the angleable metal fitting 7 and the pillar 1 through it. Then, when the pillar 1 is bolted onto the parapet 3 via the angleable metal fitting 7, the angle of the pillar 1 is adjusted, and after the bolting is completed, the curable viscous material 9 is filled to support the pillar 1. Fix the standing condition of.

In order to stand the anchor bolt 5 on the parapet 3, a hole for inserting the anchor bolt 5 is formed, and the hole is filled with mortar 11 to fix the anchor bolt 5 vertically. Note that, as shown in FIG. 2, the upper surface of the parapet 3 is slanted toward the indoor side, and this angle is corrected by the angleable metal fitting 7.

The angleable metal fitting 7 includes a base 13 placed on the parapet 3 and a socket 1 into which the pillar 1 is inserted.
5 and are cast from metals such as aluminum alloy and iron alloy, respectively.

The upper surface of the base 13 which receives the socket 15 is a convex surface 17 which is curved in an arc shape in the front-rear direction.
The angle of the socket 15 is adjusted by the relative positional relationship with the curved convex surface 17, and it is necessary to change the position of the base 13 in relation to the position with the socket 15.
A through hole 19 to be inserted into the anchor bolt 5 is formed particularly long in the front and rear. In any case, since the through hole 19 is filled with the curable viscous material 9, it needs to be formed widely. An annular tight material 21 made of an elastic sheet is adhered to the lower surface of the base 13 to prevent the curable viscous material 9 from leaking. Further, the tight material 21 improves the fixability to the parapet 3.

The socket 15 is a container having a deep holding hole 22 into which the support column 1 is inserted, and a through hole 24 for the anchor bolt 5 is provided at the center of the bottom of the socket 15. A curved concave surface 23 is formed in a shape along the convex surface 17, but a concave cutout portion 25 is provided on the lower surface thereof so that the curable viscous material 9 can be filled with each other, and the curved concave surface 23 hangs down into the through hole 19 of the base 13. A pair of legs 2
7, 27 are formed so as to face the through hole 24 therebetween. Further, in order to fill the curable viscous material 9, an injection hole 29 reaching the through hole 19 of the base 13 is obliquely formed on the front surface on the indoor side. Further, before and after that, a screw-in hole 33 of a push screw 31 for stopping the support 1 is provided. Then, a fitting portion 35 for fitting a lid 37 that hides the injection hole 29 and the set screw 31.
Is formed. In addition, the curved concave surface 23 of the socket 15
Also, the tight material 32 is bonded.

The support column 1 is formed by extruding an aluminum alloy into a square tubular shape, and has screw pockets 38, 38, ... For mounting the headstock 36 on the inner surface. A sealing plate 39 is fixed to the lower end of the column 1, and a hole 41 is formed in the center of the sealing plate 39 through which the anchor bolt 5 passes.
Is provided. The reinforcing core material 43 is received by the sealing plate 39. Reference numeral 44 is a height adjusting plate of the column 1.

The reinforcing core material 43 is a cylindrical steel tube, and the curable viscous material 9 is filled into the reinforcing core material 43 from above.
.. through which the curable viscous material 9 passes, are formed in the lower end portion so that it also flows out to and from the column 1. In order to screw the support column 1 to the anchor bolt 5, in the reinforcing core member 43, the anchor bolt 5
Pass the washer 40 through and tighten the nut 42. At that time, an instrument such as a T-bar wrench is used.

If necessary, the handrails are assembled in a factory by dividing them into several pieces. At that time, the eye plate 47 to which the headstock 36 is attached is stopped by the bispoke 38 and the headboard 36 is retrofitted. However, a cutout 49 is provided in the eye plate 47 at a position corresponding to the reinforcing core member 43 so as not to hinder filling.

Regarding the injection of the curable viscous material 9 into the reinforcing core material 43, the capsule 51 in which it is wrapped in a rupturable film is used.
After tightening the nut 42, the capsule 51
Was dropped into the reinforcing core material 43, and the capsule 51 was ruptured by sticking it from above with a stick or the like. In this way, the lower end of the column 1 can be filled while maintaining the flow. Further, it is natural that the curable viscous material 9 may be directly injected from the notch 49 without using the capsule 51.

An epoxy resin adhesive was used as the curable viscous material 9, but the material is not particularly limited as long as it cures with time and has the required strength. It is also possible to use fast-acting, non-shrink mortar.

[0022]

As described above, according to the present invention, the handrail support can be erected straight, and in particular, even when the upper surface is largely inclined forward and backward like a parapet, the handrail support can be greatly raised. Can be modified. In addition, since there is only one anchor bolt, the pillar is bolted through the angleable metal fittings, and in addition, the standing state of the pillar is determined by the hardening of the curable viscous material. Is firmly held. Further, since the support base having the seat plate is not used and the bolt tightening is extremely reduced, the workability is improved, and the appearance of the handrail is improved, which is an excellent effect.

When the angleable metal fitting is a combination of the base and the socket (Claim 2), not only the angle can be easily adjusted, but also the tight material causes the hardened viscous material to be densely packed, so that the base and the socket are connected. Since the fixing of both of them and the connection with the anchor bolt are ensured, the above effect can be more remarkably exhibited.
