Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a synthetic resin bamboo fence having vertically-connected standing members, and more particularly to a connecting structure of standing members.
[0002]
[Prior art]
  The fourth fence has a structure in which a standing bar is arranged at a predetermined interval between the vertical fences on both sides with a predetermined interval between the vertical fences and is arranged at a predetermined interval so that the grooves are square. In addition, the Onagaki has a structure in which horizontal bamboos are arranged in the vertical direction between the vertical fences on both sides, and the standing bars are arranged at regular intervals on the front and back surfaces thereof. The standing child is made of one or two sets of round bamboo.
[0003]
  When natural bamboo material is used for the stand, the thickness of each stand and the rate of change in length are not uniform. When using a long stand, the appearance of the stand becomes uneven, and the aesthetic appearance of Takegaki declines. In order to prevent this, a conventional stand made of natural bamboo has been cut to a length in which the change in thickness is as inconspicuous as possible, and a plurality of pieces having substantially the same thickness are connected vertically. However, even if such a contrivance was made, the connecting parts of the vertical members were connected simply by abutting, so it was inevitable that the difference in the thickness of the upper and lower vertical members appeared as steps in the connecting parts, This has been accepted as a feature or characteristic of natural materials.
[0004]
  In recent years, however, synthetic resin bamboo fences, which are made by assembling a synthetic resin molded article having the appearance of a bamboo and a frame made of a metal shape, attached to a column, are not only rich in Japanese emotion. Because of its excellent durability, weather resistance, and corrosion resistance, it is often installed in Japanese-style gardens and Japanese-style restaurants, but conventional synthetic resin bamboo fences lay multiple vertical bamboos horizontally. A synthetic resin molding plate having the appearance arranged in the above is bonded to the frame, and a synthetic resin presser bamboo having the appearance of a split bamboo is fixed to the front side or the front side and the back side of the synthetic resin molding plate with a circular cross section. The Kenninji wall, which is composed by fixing the main body of the bamboo fence to the column, occupied the majority.
[0005]
[Problems to be solved by the invention]
  Even if the fourth and third fences are made of synthetic resin, the synthetic resin stand is required to have the same appearance as the natural bamboo stand. It is made of a synthetic resin tube having a thickness. Also, in order to be able to easily respond to requests for various heights of bamboo fences, prepare a bamboo fence body with a relatively low height, and connect a plurality of bamboo fence bodies vertically to construct a bamboo fence of the desired height It is in. When this is applied to the fourth and third fences, the lower bamboo fence stand and the upper bamboo fence stand are connected vertically. It was just a match.
[0006]
  On the other hand, since a stand made of a synthetic resin molded product has a large thermal expansion / contraction rate, when connecting by simply butting the end of the stand in the same manner as in the past, there is a gap generated at the connecting portion during heat shrinkage. Enlarge and detract from the overall beauty of the bamboo fence. In addition, if the gap between the end portions of the stand is set small from the beginning so that the gap is not conspicuous, the stand will be deformed by the pressing force between the ends of the stand during thermal expansion, which also impairs the beauty of Takegaki. There was a problem.
[0007]
  In addition, when constructing a tall bamboo fence, the bamboo fence main body is connected to the top and bottom, but in the case of a stud-type bamboo fence, the top horizontal rail of the lower bamboo fence main body and the bottom of the upper bamboo fence main body In contrast, in the case of a universal pillar type bamboo fence, the uppermost horizontal rail of the lower bamboo fence body and the lowermost of the upper bamboo fence body are usually installed. It is common that the horizontal bars are separated from each other by the thickness of the intermediate bracket interposed between the horizontal bars. Therefore, since the size of the gap between the vertically-connected standing bars varies depending on whether the pillar-shaped bamboo fence or the free-column-shaped bamboo fence is used, it is not easy to deal with the gap generated in the connecting portion of the standing bars.
[0008]
  The present invention has been made in view of the above points, and the first problem is that in a synthetic resin bamboo fence having a stand such as a four-eyed fence or a gogaki, a gap is exposed at the connecting portion of the stand. It is intended to provide a connecting structure of the standing members that can prevent the deformation of the standing members due to thermal expansion and improve the appearance of the synthetic resin bamboo fence.
[0009]
  The second problem is that in the case of a stud-shaped bamboo fence, the uppermost horizontal beam of the lower bamboo fence main body and the lowermost horizontal beam of the upper bamboo fence main body are installed in contact with each other. In the case where the uppermost horizontal beam of the lower bamboo fence main body and the lowermost horizontal beam of the upper bamboo fence main body are spaced apart by the thickness of the intermediate bracket interposed between those horizontal beams It is another object of the present invention to provide a structure for connecting the standing members that can improve the aesthetics of the synthetic resin bamboo fence by preventing the gaps from being exposed at the connecting portions of the upper and lower standing members.
[0010]
