DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate post and a fence having an earthquake-resistant structure resistant to earthquakes. In the present specification, the term "gate post and fence" is used to mean a gate post or fence.

[0002]

2. Description of the Related Art Conventional quake-resistant structures such as gate posts and fences have been developed to be reinforced so as not to fall down due to an earthquake. A structure such as a fence for realizing this is described in the following publication. JP-A-7-243273 JP-A-56-148456 JP-A-56-10760 JP-A-56-39566 JP-A-55-165379

[0003] The above-mentioned publication describes a structure in which the fence itself is reinforced to have an earthquake-resistant structure. The publications (1) to (4) disclose a structure in which a member for reinforcing a wall is constructed adjacent to or connected to the wall separately from the wall.

[0004]

The fences and the like described in these publications have disadvantages in that the fence itself is strengthened or a reinforcing member is separately constructed, so that the construction is troublesome and the construction cost is increased. is there. Further, since the fence is constructed by laminating many blocks, it is difficult to increase the strength of the fence. This is because many earthquakes easily destroy the boundaries of many blocks. In addition, the fence constructed by stacking blocks has a drawback of having a brick-like appearance and being restricted by design. Although the blocks can be made large and have a neat design, the disadvantage is that the large blocks are very heavy and the work is extremely labor intensive.

SUMMARY OF THE INVENTION The present invention has been developed to solve these drawbacks of conventional pillars and fences. An important object of the present invention is to provide an excellent earthquake-resistant structure and a simple and easy structure. Another object of the present invention is to provide an earthquake-resistant gate post and fence that can be constructed efficiently in a short time. Further, another important object of the present invention is that the design is subject to few restrictions,
An object of the present invention is to provide a gate post and a fence having an earthquake-resistant structure that can be designed to have a beautiful appearance.

[0006]

According to the present invention, a gate column and a fence of an earthquake-resistant structure of the present invention are formed on a steel frame 1 comprising a vertical bar 1B and a horizontal bar 1A.
Is fixed vertically, and a concrete panel 2 is fixed to the surface of the steel frame 1. The concrete panel 2 is connected to the steel frame 1 with the following unique structure. (A) Concrete panel 2 has a plurality of sandwiching pieces 3 on the back.
Is fixed. (B) The sandwiching piece 3 connects the lower part of the concrete panel 2 to the steel frame 1. (C) The sandwiching piece 3 extends downward away from the back of the concrete panel 2.
The concrete panel 2 is connected to the horizontal streak 1A by holding the upper edge of the horizontal streak 1A in a state in which it can be moved in the horizontal direction with the holding piece 3. (D) The upper part of the concrete panel 2 is connected to the steel frame 1 via the sandwiching member 4 so as to be able to move in the horizontal direction.

In the concrete panel 2 connected to the steel frame 1 with the above structure, when the steel frame 1 is deformed by the earthquake, the holding piece 3 and the holding member 4 move in the horizontal direction with respect to the horizontal bar 1A. For this reason, the deformation of the steel frame 1 is absorbed by the holding piece 3 and the holding member 4, and the concrete panel 2 can be prevented from being damaged by the distortion of the steel frame 1. Further, since the concrete panel 2 is connected to the surface of the steel frame 1, the concrete panel 2 can be made large and the weight per area can be reduced.

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate the portals and fences of the earthquake-resistant structure for embodying the technical idea of the present invention, and the present invention does not specify the portals and fences of the earthquake-resistant structure as follows. .

Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

The L-type portal shown in FIG. 1 has concrete panels 2 connected to both sides of a steel frame. 5 shades on top of steel frame
Are fixed, and the end panel 6 is fixed to the end face.

FIG. 2 is a plan view of the steel frame. This steel frame 1
As shown in the front views of FIGS. 3 and 4, the vertical streak 1B and the horizontal streak 1A are connected in a square shape. 3 and 4 show front views of steel frames 1 connected at right angles to each other. The steel frame 1 shown in FIGS. 3 and 4 is connected at right angles via fixing screws 7 as shown in FIG. The fixing screw 7 penetrates the longitudinal bar 1B of the steel frame 1 to connect the two steel frames 1 together.

The steel frame 1 is composed of a vertical bar 1B and a horizontal bar 1
A is welded and connected in a square shape. The horizontal bar 1A is connected to the vertical bar 1B so as to open the groove of the C-shaped steel upward. As shown in FIG. 5, this is for inserting the sandwiching piece 3 of the concrete panel 2 and the sandwiching member 4 from above and connecting them. The steel frame 1 is fixed to a foundation with anchor bolts.

The concrete panel 2 is formed by hardening concrete by forming it into a plate shape. Preferably, a GRC panel reinforced with glass fiber is used. GRC panels are thin, light, and large.
The concrete panel 2 has a size of one sheet, for example,
The size is about 1400 × 900 mm. However, the size of the concrete panel 2 differs depending on the gate post or fence to be constructed. The concrete panel used for the gate post is designed to be large enough to make up one plane. The concrete panel used for the fence has a height substantially equal to the height of the fence and a width of 300 to 1000 mm. Concrete panels are formed with an uneven pattern on the surface, or
It can be colored and beautifully finished.

The lower part of the concrete panel 2 is
To the steel frame 1. FIG. 5 shows a state in which the holding piece 3 holds the steel frame 1. The sandwiching piece 3 in this figure is fixed to the back of the concrete panel 2 with a set screw 9. The holding piece 3 fixes an elastic piece 3B that is elastically deformed to a plate 3A that is fixed with a set screw 9. The lower end of the elastic piece 3B is curved in a tapered shape so that the elastic piece 3B can be smoothly inserted from above into the horizontal streak 1A, which is a C-shaped steel, so that the space between the elastic piece 3B and the concrete panel 2 is increased. The plate 3A is a metal plate having substantially the same thickness as the horizontal streak 1A, and has an elastic piece 3B fixed to its surface. When the plate 3A is fixed to the back surface of the concrete panel 2 of the sandwiching piece 3 having this structure, the thickness between the elastic piece 3B and the concrete panel 2 becomes substantially equal to the thickness of the horizontal bar 1A. Therefore, the elastic piece 3B can be fixed to the concrete panel 2 and connected to the horizontal streak 1A.

The sandwiching piece 3 is fixed to a position where the horizontal bar 1A can be sandwiched in a state where the concrete panel 2 is connected to a fixed position of the steel frame 1. Further, the sandwiching pieces 3 are fixed to the lower part of the concrete panel 2 at fixed intervals, and connect a plurality of portions of the concrete panel 2 to the horizontal streak 1A. The narrow concrete panel 2 can be connected to the steel frame 1 by two sandwiching pieces 3. The wide concrete panel 2 connects the concrete panel 2 to the steel frame 1 using three or more sandwiching pieces 3.

When the steel frame 1 is deformed due to an earthquake or the like, the holding pieces 3 are connected so as to be relatively movable with respect to the horizontal streak 1A. The reason why the sandwiching piece 3 moves with respect to the horizontal streak 1A is to prevent the concrete panel 2 from being damaged. Therefore, the force with which the sandwiching piece 3 moves with respect to the horizontal streak 1A is set to be weaker than the force with which the concrete panel 2 is damaged.

The upper part of the concrete panel 2 has a clamping member 4
To the steel frame 1. The holding member 4 includes the holding piece 3.
The structure may be the same as that of FIG.
Has a shape different from that of the clamping piece 3. The holding member 4 in this figure is composed of a holding metal member 4A bent in a U-shape and a holding screw 4B screwed into the holding metal member 4A.
A female screw for screwing the holding screw 4B is provided through the holding metal fitting 4A. The sandwiching member 4 having this structure screwes the sandwiching screw 4B into the sandwiching metal fitting 4A, and sandwiches the concrete panel 2 with the transverse bar 1A which is a C-shaped steel. Nipping screw 4B
Is tightened so that the concrete panel 2 can move laterally with respect to the steel frame 1 before the concrete panel 2 is damaged when the steel frame 1 is deformed due to an earthquake or the like. The clamping member 4 is
Preferably, the same number of clamping pieces 3 are used to connect a plurality of locations of the concrete panel 2 to the steel frame 1.

The pillar shown in FIG. 5 is fixed with a cap 5 in order to finish the upper surfaces of the steel frame 1 and the concrete panel 2 neatly. The cap 5 has a U-shaped cross section and covers the upper edge of the surface of the steel frame 1 and the concrete panel 2. The cap 5 is made of the same material as that of the concrete panel 2 and is formed into a shape that decorates the surface neatly. The cap 5 is the upper horizontal line 1
A is fixed to the fixing hardware 10 fixed to A through the connecting screw 8 with the tapping screw 11. After fixing the cap 5 with the tapping screw 11, a hole provided in the head of the tapping screw 11 is caulked to finish the surface. The cap 5 is connected to the steel frame 1 after fixing the concrete panel 2 to the steel frame 1.

As shown in FIG. 2, the end panel 6 has a buried nut 12 inserted in the back surface. Buried nut 1
2, a fastening screw 13 that penetrates the longitudinal bar 1B is screwed. The fastening screw 13 connects the end surface panel 6 to the vertical bar 1B. The end panel 6 is also made of the same material as the concrete panel 2 and has a clean surface. As shown in FIG. 2, the structure for connecting the buried nut 12 to the vertical bar 1 </ b> B
The feature is that the screw does not appear on the surface of. However, it can also be connected to the vertical streak with a screw penetrating the end panel. The end panel 6 is connected to the steel frame 1 before connecting the concrete panel 2. This is because when the concrete panels 2 are connected, the fastening screws 13 cannot be screwed.

FIG. 6 shows the connecting portion of the fence. The fence is long,
As shown in this figure, a plurality of steel frames 1 used for the above-mentioned portal columns are connected in a row and used. The steel frames 1 are connected in a row by an integral screw 14 that penetrates the longitudinal bar 1B. The concrete panel 2 is fixed to both surfaces of the connected steel frame 1 via the above-mentioned holding piece and holding member. Further, a cap is fixed to the upper surface, and an end panel is fixed to the end surface. The cap and the end panel can also be connected to the steel frame 1 with the same structure as the L-shaped post.
