Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pseudo-wooden shelf that is installed in parks, squares, promenades, etc. and is made of pseudo-wooden crossbars and pseudo-wooden supports.

[Conventional technology]

BACKGROUND ART In recent years, fake wood shelves that do not harm the natural environment and have the grain and color of natural wood and have excellent water resistance and corrosion resistance have been used as shelves installed in parks, plazas, promenades, etc.

Such a pseudo-wooden shelf is made of, for example, a pseudo-wooden crosspiece made of cement, plastic, etc., whose core material is a steel pipe, etc., and whose surface is formed into a wood-like texture; cement.

It is composed of pseudo-wooden supports made of plastic or the like.

Conventionally, the above-mentioned pseudo-wooden crosspiece and pseudo-wooden support are joined by inserting the tip of the crosspiece into a hole provided in the radial direction of the support, and filling the inserted part with joint material, or by joining the two at the inserted part. This was done by connecting them with bolts, etc.

[Problem to be solved by the invention]

However, with the above-mentioned method, the crossbars cannot be installed unless the spacing between the supports is appropriate for the length of the crosspieces, and the crossbars tend to fall off, resulting in extremely poor workability. .

As a means to solve the above problem,
No. 6 discloses that a rod rod having a large diameter portion at a predetermined position is inserted into a notch recess provided in the support, passing through the support.
A camp that can be inserted into the rod rod and has a hole larger in diameter than the rod rod is fitted into the exposed end of the core material at the end of the crosspiece, and in this state, by inserting the rod rod into the hole in the cap, the rod can be cut. A pseudo-wood shelf is disclosed in which the ends of the crosspieces are fitted into the cutout recesses, and the gap between the cutout recesses and the crosspieces is filled with a joint material such as mortar to fix the crosspieces.

In addition, Japanese Utility Model Publication No. 62-91856 discloses that a bracket for connecting a crosspiece is provided protruding from a support, and the end of the crosspiece is inserted into the bracket through a notch formed at the end of the crosspiece and fixed with bolts, etc. A pseudo-wood shelf is disclosed.

However, the former (Utility Model Publication No. 62-3496 f1!
In this method, the crosspiece is connected to the support by a camp fitted into the end of the crosspiece, which requires a cap with a special shape that fits the cross-section of the crosspiece. It takes time and effort. Furthermore,
The crosspieces are fixed to the columns using joint material filled in the gap between the notch of the column and the crosspieces, so filling the joint with the joint material is not easy. There are problems such as physical deterioration and insufficient fixation.

In addition, the latter requires a specially constructed bracket to join the crossbars, and the manufacturing of this bracket and the installation of it to the pillars are complicated, which creates the problem of requiring a lot of effort and expense. be.

Therefore, an object of the present invention is to easily and reliably connect and fix a crosspiece to a support without requiring any special equipment or brackets, and to be economical and durable. Our goal is to provide a pseudo-wooden shelf.
