Description

  INDUSTRIAL APPLICABILITY The present invention is used for a fence, in particular, a fence whose lower end is fixed to an upper surface of a parapet or a base and is attached to a pillar that is erected through a headboard provided on the upper surface, and a pillar standing structure of the fence. New pillar pedestal.

Generally, for this type of fence post, aluminum hollow material with a rectangular cross-section is used for aesthetics and rust prevention, but the hollow material is made of aluminum and tends to be insufficient in strength. Therefore, a flat steel base is welded to the lower end of a stainless steel or other steel pillar anchor, and the base is fixed to the upper surface of the parapet or base (hereinafter referred to as a base) with screws or the like. The pillar anchor is passed through the hole of the headboard, the headboard is fixed to the base, the pillar anchor is placed in the pillar, and a screw is screwed into the pillar anchor from the pillar to fix the pillar to the pillar anchor.
nothing special

In the above-mentioned conventional column erection structure, the column anchor is relatively short, so that the column reinforcement effect is not sufficient, and there is a risk that the column will be plastically deformed by wind force applied from a fence panel or a human load applied from a handrail. was there. In addition, since the pillar anchor penetrates the hole of the headboard and extends upward, rainwater may enter the upper surface of the foundation from the gap between the pillar anchor and the headboard, so that waterproof performance or water stopping performance is required. Since the screw is screwed into the pillar anchor from the long hole provided in the pillar, which is a hollow material, rainwater permeates into the pillar through the gap of the long hole, so that drainage performance is required.
However, conventionally, improvement of column strength, but that attempts to addition of waterproof and waterproofing performance and the drainage performance is proposed, it can not be said that the strength of the standoff is sufficiently improved, waterproof waterproofing and drainage Because the structure for the construction was complicated, it took a lot of time for construction.

  The present invention has been made in view of the above points, and the first problem to be solved is that the construction can be easily performed with a simple structure, the strut strength is increased, and the waterproof / drainage performance is excellent. The object is to provide a fence using an upright structure. The second problem is to provide a new pillar pedestal for fence post standing structure that greatly contributes to the waterproofing and drainage performance of the pillar standing structure.

In order to solve the first problem, the fence according to the present invention has a lower end welded to a pedestal, vertically elongated holes formed in at least two locations, rust-proofed together with the pedestal, and the pedestal attached to the base of the fence. A hollow steel pillar anchor fixedly installed on the upper surface and the pillar anchor fixed to the base are inserted into a hole of the headboard, and when the headboard is fixed to the base, A sealer mounted so as to close a gap between the periphery and the outer peripheral surface of the support anchor; and a frame portion and a convex portion provided on an inner peripheral surface of the frame portion, and after the sealer is mounted When the pillar anchor is inserted inside the frame part and placed on the upper surface of the headboard, the convex part is in contact with the outer surface of the pillar anchor for positioning, and the space below the convex part The sealer, and the frame portion and the support. A column base that is fixed by filling a sealing material in a gap formed between the anchors, and the column anchor is inserted, and the lower end surface is in contact with the upper surface of the frame part of the column base itself. It is characterized in that it has a strut standing structure comprising a strut that is fixed by being screwed into a screw receiving member provided inside the strut anchor through a vertically long hole of the strut anchor .
With the above configuration, since the pillar anchor is made of steel, the aluminum pillar is reinforced. The longer the anchor anchor length, the greater the reinforcing effect. Since the screw that connects the column to the column anchor is screwed into the aluminum screw receiving member, it is easy to screw in. Moreover, since the screw hole is not drilled in the field in the steel pillar anchor, rust does not occur. The gap between the outer peripheral surface of the pillar anchor inserted into the hole of the headboard and the hole edge of the headboard is sealed by a sealer, and a pillar base is placed on the upper side of the sealer, and the space between the pillar base frame and the pillar anchor Since the sealing material is filled in the gap, the rain finish is good, and the waterproof performance and the waterproof performance are excellent. In addition, since the sealer is housed inside the frame portion of the column base, it is not exposed to the outside.

It is desirable that the sealer is an L-shaped sealer member arranged in an inverted symmetrical shape and continuous in a rectangular shape.
When such a sealer material is used, even if the dimensions of the support anchors are changed, the same member can be used simply by cutting it according to the dimensions of the support anchors. Therefore, the manufacturing cost reduction effect can be obtained. Further, a sealer can be easily provided around the pillar anchor.

The column pedestal that solves the second problem has a frame portion and a convex portion provided on the inner peripheral surface of the frame portion, and the frame portion has a column anchor erected on the upper surface of the base inside. When inserted and placed on the top of the headboard, the convex part contacts the outer surface of the pillar anchor for positioning, and a sealer placed on the top of the headboard around the pillar anchor is placed in the space below the convex part. It is characterized in that a sealing material filling space is formed between the frame portion and the column anchor.
When a column anchor erected on the upper surface of the base is inserted inside the frame portion and the frame portion is placed on the upper surface of the headboard, the convex portion comes into contact with the outer surface of the column anchor to perform positioning. Further, a sealer placed on the upper surface of the headboard is accommodated around the support anchor in the space below the convex portion. A sealing material filling space is formed between the frame portion and the column anchor. When the sealing material is filled in the sealing material filling space, the space between the pillar anchor and the frame portion of the column base is sealed.

It is desirable that the column base is formed with a drainage groove for draining from one side of the frame part to the other side on the upper surface of the frame part.
In the case where such a drainage groove is provided, rainwater that enters the column and flows down to the column base is drained from the drainage groove to the outside.

  According to the first aspect of the present invention, the aluminum column is reinforced by the steel column anchor, and the longer the column anchor is, the greater the reinforcing effect is obtained. Since the screw connecting the column to the column anchor is screwed into the aluminum screw receiving member, the screw is easy to screw in, and no screw hole is drilled in the steel column anchor at the site, so rust does not occur. The gap between the outer peripheral surface of the pillar anchor inserted in the hole of the headboard and the hole edge of the headboard is sealed with a sealer. Since the sealing material is filled in the gaps, the rain finishes well and the waterproof performance is excellent. In addition, since the sealer is housed inside the frame portion of the column base and is not exposed to the outside, the column stand only exposes the outer periphery of the frame portion, so that the appearance of the column rising portion is also good.

  According to the invention of claim 2, since the siller material is L-shaped, the same siller material is used only by adjusting the length by cutting the same siller material according to the size of the column anchor, even if the size of the column anchor changes. Therefore, an effect of reducing the manufacturing cost can be obtained, and a sealer can be easily provided around the support anchor with little effort.

  According to the invention of claim 3, the column base is attached to the base of the column anchor standing upright on the upper surface of the base, and the sealer is easily concealed and filled with the sealing material, and the waterproof performance at the lower end of the column is ensured. Can be obtained.

  According to invention of Claim 4, the column base which is a single member can be equipped with the drainage performance of the rain water which infiltrated into the support | pillar in addition to the waterproof performance with respect to a base.

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

Is a perspective view of the top surface, and (b) is a bottom view. FIG. 8 is a perspective view showing the sixth step of standing upright, FIG. 9 is a longitudinal sectional view showing the standing structure at the end of the sixth step, and FIG. 10 is a sectional view taken along line XX in FIG.

In FIG. 1, 1 is a base, 2 is a headboard fixed to the upper surface of the base, 3 is fixed to the upper surface of the base, and is a support column standing upright through the headboard, 4 is fixed to the upper end of the supporter A handrail 5 is a panel attached between the columns .

In order to erect the column 3 shown in FIG. 1, as a first step, as shown in FIG. 2, the column anchor 6 is fixed to the upper surface of the base 1. Post anchor 6, as shown in FIG. 3, of iron or steel cross-sectional shape is formed in a rectangular hollow member, Vertical holes 61 are formed in at least two places above and below, the screw holes 62 in the vicinity of each longitudinal slot formed Has been. And the lower end part of the support | pillar anchor 6 is welded to the center of the base 7 with steel plane shape rectangular. In the pedestal 7 , a drain hole 71 is formed in the center, and a long hole 72 is formed in the vicinity of the four corners. The column anchor 6 is plated or other rust-proofed with the pedestal 7 welded thereto.

  Further, a belt-like screw receiving member 8 made of aluminum is provided on the inner surface of the wall in which the vertically long hole 61 of the support anchor 6 is formed, and is fixed to the support anchor by a screw 63 screwed from the screw hole 62. Both end portions of the screw receiving member close the vertically elongated hole 61 of the column anchor. Since the screw 63 is screwed into the pillar anchor 6 subjected to plating or other rust prevention treatment, the screw 63 does not cause rusting.

  Thus, the pillar anchor 6 provided with the screw receiving member 8 on the inside has the base 7 placed on the upper surface of the base 1 with the vertically long hole 61 facing the inside of the balcony or the inside of the fence, and from the long hole 72 of the base. The coach screw 73 is screwed into the base and is erected. The lengths of the pillar anchor 6 and the screw receiving member 8 are determined according to the height of the handrail 4, that is, the height of the pillar 3, but are close to the height of the pillar so that the greatest reinforcing effect can be obtained. The length is, for example, about 800 to 1300 mm.

  Subsequently, as shown in FIG. 2, as a second step, the headboard 2 is lowered from above the base 1, and the pillar anchor 6 is inserted into the hole 21 having a shape similar to the cross-sectional shape of the pillar anchor formed in the headboard. As shown in FIG. 4, the headboard is close to the upper surface of the base 1 and is elastically fitted and fixed to a known holder (not shown). In this state, as shown in FIG. 4, the column anchor 6 stands upward from the hole 21 of the headboard 2. At this time, there are many cases in which a slight gap is generated between the outer peripheral surface of the column anchor 6 and the periphery of the hole 21 of the headboard 2.

  Therefore, as a third step, as shown in FIGS. 4 and 5, a sealer 9 is provided on the upper surface of the headboard along the gap to close the gap. This sealer 9 cuts two sealer members formed in an L shape from a synthetic rubber or plastic material into a length that matches the width of two adjacent side surfaces of the column anchor 6, and cuts them into each other of the column anchor 6. It arranges in the reverse symmetrical form on the opposite side, and seals the gap by continuing the rectangle. The sealer 9 can also be formed as a single rectangular ring. However, in that case, it will be dedicated to the pillar anchor of a predetermined size, and it is troublesome to fit it from the upper end of the pillar anchor and pull it down to the top of the headboard of the base so that it is troublesome. In addition, if an L-shaped sealer member is made and cut and used in accordance with the dimensions of the column anchor, it can be applied to the column anchors of various sizes with one type of sealer member, so that the manufacturing cost can be reduced.

  Next, as shown in FIG. 5 and FIG. 6, as shown in FIGS. 5 and 6, the column base 10 is inserted into the support anchor 6 from above and placed on the upper surface of the headboard 2 to accommodate and conceal the sealer 9. At the same time, the sealing material 11 is filled and the space between the column base 10 and the outer peripheral surface of the column anchor 6 is sealed and fixed. More specifically, as shown in FIG. 7, the column base 10 includes a rectangular annular frame portion 101 having the same shape as the cross-sectional shape of the column anchor 6. The frame portion 101 has a flat surface on the upper surface and has an inner peripheral wall 102 that rises continuously in a rectangular shape along the inner periphery. And it has the convex parts 103 and 104 which protrude mutually opposite in the height direction middle of the internal peripheral surface of the internal peripheral wall 102. As shown in FIG. A space for accommodating the sealer 9 is formed in a portion surrounded by the inner peripheral surface of the inner peripheral wall 102 below the convex portions 103 and 104, and the inner peripheral wall 102 above the convex portions 103 and 104 is formed. A sealing material filling space, which will be described later, is formed in a portion surrounded by the peripheral surface. Therefore, the size of the inner peripheral surface of the frame portion 101 is substantially matched with the outer dimension of the sealer 9. Further, a drainage groove 105 that opens to the upper surface is formed on one opposite side of the frame portion 101 at a position close to the inner peripheral wall, and the drainage groove 105 opens laterally on one of the other opposite sides of the frame portion. Has been.

  In this way, as shown in FIG. 6, the column anchor 101 is inserted inside the frame portion 101 of the column base 10 and the side opening of the drainage groove 105 is directed toward the inside of the balcony or the inside of the fence. Is placed on the upper surface of the headboard 2, the projections 103 and 104 come into contact with the outer surfaces of the column anchor 6, and the column base 10 is positioned at a predetermined position. At that time, the previously installed sealer 9 is accommodated in the sealer accommodating space of the column base 10 and is pressed by the inner peripheral wall 102 and the convex portions 103 and 104. Accordingly, the sealer 9 is fixed without being bonded to the upper surface of the headboard 2 or the like, and the effect of preventing rainwater intrusion between the pillar anchor 6 and the headboard 2 can be obtained by the sealer.

  Further, a sealing material filling space opened upward between the inner peripheral wall 102 on the upper surface of the column base and the column anchor 6 is filled with a sealing material 111 from, for example, the tube 11 or the like, and the space between the column and the frame portion 101 is filled. Fully sealed. Therefore, high watertightness is ensured between the lower part of the pillar anchor 6 and the headboard 2.

  As the last step, as shown in FIGS. 6 and 8, the column 3 made of aluminum hollow material having a rectangular cross section is lowered from above the column anchor 6, and the column anchor 6 is placed in the hollow portion 31. , The lower end surface of the column 3 is brought into contact with the flat upper surface of the frame portion 101 of the column base 10, and a screw 33 is screwed through a hole 32 formed in the column 3 in advance. Since the screw 33 is screwed into the screw receiving member 8 facing the vertically long hole 61 of the column anchor 6, the column 3 is firmly and firmly fixed to the column anchor 6.

  The lower end surface of the column 3 is in close contact with the upper surface of the frame part 101 of the column base 10, but the drain groove 105 of the column base is formed at a position lower than the upper surface of the frame unit 101. Rainwater that may enter the water flows down along the inner wall surface of the column 3 and is guided by the sealing material 111 filled in the upper surface of the column base, flows through the drainage groove 105, and enters the balcony or fence from one end thereof. Drained inside.
