Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence post connection structure.

[0002]

2. Description of the Related Art When connecting fences arranged between stanchions to the stanchions, joint fittings are screwed to the upper and lower sides of the stanchions from the sides, and the fence edges are fitted to the joint fittings. The method of fixing is taken. (For example, Japanese Utility Model Laid-Open No. 60-68252) However, according to such a strut connection structure of a fence, various types according to the number of fences to be attached to the strut such as an intermediate strut, side strut, and corner strut, or the orientation of the fence. In addition to having to significantly reduce productivity, it is necessary to prepare columns in the form of, and when a contractor purchases these, the number of columns must be calculated according to the type of columns. It was complicated in terms of logistics and construction site.

Further, according to the method of fixing the joint metal fittings to the upper and lower side portions of the support pillar from the side surface and engaging with the fence's furring edge to fix it, if the constructed fence is damaged, it can be easily removed. Since it was not possible, the repair work was extremely troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention aims to simplify the handling in production, distribution, and on-site construction by constructing fence middle pillars, side pillars, corner pillars, and the like with members of the same shape. With the goal.

[0005]

Means for Solving the Problems The inventors of the present invention have made extensive studies in view of such circumstances, and as a result, arrange a fence between hollow columns and fix the upper and lower side portions of the fence to the columns. In a fence strut connection structure, a vertical joint fitting with locking projections with the same cross-section on multiple side faces is fitted and fixed to the top of the hollow strut, and is fitted to the upper edge of the fence. A locking protrusion with the same cross-section is formed on one side of the fitting, and the screw is pushed into the small hole created by engaging the locking projection of the vertical fitting and the locking projection of the horizontal fitting. It has achieved the intended purpose of integrating the two.

[0006]

According to the present invention, all the pillars such as the middle pillar, the side pillars, and the corner pillars have the same hollow shape, and a plurality of locking projections having the same cross section are formed on the side surfaces. The vertical joint metal fittings are fitted and fixed to the top of the hollow column, and the horizontal joint metal fittings that have locking projections with the same cross-section at the side edges are used. Engage with the locking projection of and press the screw into the space between the locking projections of both fittings to integrate both fittings to form the upper joint of the column, The lower joints may be provided by a conventional method, and the upper and lower furring edges of the fence may be fixed to both joints.

The shapes of the locking projections formed on the vertical joint fitting and the horizontal joint fitting of the present invention are continuous in the vertical direction, and the cross-section thereof is the same as the locking projections of the vertical fitting fitting and the horizontal fitting fitting. A small hole surrounded by both locking projections is formed when the locking projections are engaged, and both fittings are integrated by pushing a screw into the small hole. The shape is such that one side of one fitting is provided with locking projections with a pair of ends bent outward or inward.
On the side surface of the other joint metal fitting, a pair of end portions are provided with locking protrusions bent inward or outward.

Since it is sufficient to connect fences from up to three directions to this type of support, the vertical joint fittings are provided with locking projections on three sides and fitted to the support to form the locking projections of the vertical fitting. It is possible to fix the overlapping part of the pillar to the non-existing surface. In the practice of the present invention, when the clearance between the pillar and the fence is small and it is necessary to lower the fence from diagonally above, the lower joint portion of the pillar is formed in a concave shape or the side of the lower furring edge of the fence. The lower end is cut out, and the upper horizontal joint metal fitting is fixed in advance to the upper furring strip of the fence, and the fence is arranged between the opposing columns.After that, the locking projection of the vertical joint metal fitting and the horizontal joint metal fitting are A screw may be pushed between the locking protrusions.

Further, the vertical joint fitting and the horizontal joint fitting of the present invention can be manufactured by cutting an aluminum mold material,
Suitable for mass production. In carrying out the present invention, a notch is provided on the upper end side of the hollow pillar, and the side end of the horizontal joint fitting to which the upper furring strip of the fence is fitted can be fitted and fixed to the notch of the pillar. it can. Hereinafter, the present invention will be described specifically with reference to examples.

EXAMPLE A vertical joint fitting 2 having a pair of L-shaped locking projections 3 and 3 whose ends are bent outwardly on three outer surfaces of a rectangular main body is prepared by processing an aluminum die member, and a predetermined position is prepared. Vertical fittings 2 are screwed to the tops of the columns 1, 1 ... Standing upright, and a pair of L-shaped locking protrusions 4 and 4 made of aluminum mold material with one end bent inward are formed. The horizontal joint fitting 5 is engaged with the vertical joint fitting 2, and the vertical joint fitting 2
Screwing 7, 7 into the small holes 6, 6 formed by the locking projections 3 and 3 of FIG. The lower joint portion 10 is attached by screwing the joint fitting 9 to the lower side of the inner surface where the columns 1 and 1 face each other.

The fence 11 is provided with a hollow upper furring strip 12 and a hollow lower furring strip 13 with a lower side edge of the lower furring strip 13 cut away. Are fitted to the horizontal joint fittings 5 and the lower furring strip 13 is suspended on the joint fittings 9 of the lower joint portion 10 and screwed. FIG. 3 shows an intermediate pillar for linearly applying the fence 11, and FIG. 4 shows the fence 1.
5 shows the construction procedure of the upper joint portion 8 in the side pillar of the fence 11 in which the intermediate pillar 1 is orthogonally applied. 14 in the figure
Is a protective cap, which is provided by extending a mounting piece 15 protruding downward from the inside of the lower end thereof to the overlapping portion of the column 1 and the vertical joint fitting 2 and screwing them.

[0012]

According to the present invention, the vertical joint fitting having the locking projections formed on the plurality of side faces is fitted and fixed to the top of the hollow column, and is fitted to the upper furring strip of the fence. Since both side fittings are engaged with each other by forming the locking projections on the side ends, the locking projections of the horizontal fittings that fit on the fence are engaged with the locking projections of the vertical fittings at appropriate positions. Since all that is required is one type of pillar, it can be used for all of intermediate pillars, side pillars, corner pillars, etc., which improves productivity, simplifies logistics, and saves on-site construction. .

Further, according to the strut connecting structure of the present invention, a vertical joint fitting having a locking projection having the same cross section in cross section is provided at the top of the strut, and the side end of the horizontal joint fitting fitted to the upper furring strip of the fence. A locking projection with the same cross section is formed on the, and the screw is pressed from above into the small hole created by engaging the locking projection of the vertical joint fitting and the locking projection of the horizontal joint fitting to integrate both joint fittings. Since it is a thing, you can pull up the fence by removing the protective cap and removing the screw in the small hole,
It is extremely easy to perform replacement work when the constructed fence is damaged.
