Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pseudo-wooden fence assembled by joining a pseudo-wooden pillar to a pseudo-wooden crosspiece, and specifically relates to an improvement in the joint structure between the said pillar and the crosspiece. This refers to a single-column structure in which the core material is made of artificial wood, steel pipes, etc., and the outer layer is hardened with an outer layer material such as a cement compound.

(Prior art) When assembling a pseudo-wooden fence by joining pseudo-trees together, the joining structure has conventionally been to cut out the outer layer material at appropriate locations A and B around the periphery of the upright pillar 1, and then use these notches. A structure in which the ends of the crosspieces 2, 2 are inserted into the notches and the gap between the notches and the crosspieces is filled with joint material, or a structure is formed in a part of the circumference of the vertical pillar 1 as shown in Figure 2. A structure was adopted in which connecting fittings 3, 3 were provided in the notches A, B, and cross pieces were fixed to the fittings 3, 3 by tightening bolts.

(Problems to be solved by the invention) By the way, the joining structure shown in Fig. 1 has two problems.
If the spacing between the book pillars is not appropriate for the length of the crossbars, it will be difficult to assemble the crossbars, and even if they are assembled, they will easily fall off, and the horizontal strength will be weak. In addition, when assembling, the joint material is filled with the crosspiece placed on the bottom surface of the notch, so the center of the notch and the center of the crosspiece do not match, resulting in a large manufacturing error. ing. In addition, with the joint structure shown in Figure 2, each crosspiece must be fixed to the vertical column by bolting, which is a cumbersome process. Since the fence is connected, the spacing between the two pillars must be stricter than the joint structure shown in Figure 1, and if the fence is even slightly bent, it will be difficult to connect the connecting fittings and the crossbars. However, there is a problem in that it is impossible to assemble the crossbars.

(Means for Solving the Problem) The artificial wooden fence of the present invention is provided by cutting out the outer layer material at appropriate places around the artificial wooden pillars until the core material of the artificial wooden pillars is exposed, and inserting the artificial wooden crossbars into the notched recesses. The faux wooden fence has a structure in which the inner shape of the cutout recess is larger than the outer shape of the end of the faux wooden crosspiece, and the total length in the longitudinal direction is larger than the diameter of the core material. A rod that is sufficiently long and has a large diameter portion located a certain distance toward the center from one end in the longitudinal direction is inserted in the diametrical direction into the core exposed by the notch. A cap that can be inserted into the rod and has a hole with a diameter larger than the outside diameter of the rod is fitted into the end of the core material exposed at the end of the crosspiece, and in this state, the hole in the cap is inserted into the rod. By being inserted into the rod, the vertical post and the crosspiece are joined with the end of the crosspiece being loosely fitted into the notch recess.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 3 is a detailed sectional view of the pseudo-wooden fence of the present invention, in which reference numeral 11 indicates a pseudo-wooden pillar made of a core material 12 hardened with an outer layer material 13 such as a cement compound, and 14 is the same as the above-mentioned pillar 11. , is a pseudo-wooden crosspiece consisting of a core material 15 and an outer layer material 16. The upstanding pillar 11 has cutout recesses A and B for joining the crosspiece 14 by cutting out the outer layer material at appropriate locations around the side surface thereof. Inner shape (inner diameter dimension) of these notched recesses A and B
is formed to be larger than the outer shape (outer diameter dimension) of the crosspiece 14, and is configured so that the crosspiece 14 can swing in its diametrical direction with the ends of the crosspiece 14 fitted into the notch recesses A and B. has been done.

Reference numeral 17 denotes a rod having a large-diameter portion 18 formed at a certain distance toward the center from one end in the longitudinal direction, and is inserted in the diametrical direction into the core material 12 exposed to the outside by the notch. There is. The large diameter portion 18 prevents the rod 17 from coming off from the core material 12, and
It also functions to regulate the insertion depth of the rod 17. Reference numeral 19 denotes a cap having a hole 20 that can be inserted into the rod rod 17, and is fitted into the open end of the core material 15 from the end of the crosspiece 14, and is inserted into the rod rod 17 in the fitted state. Ru. Note that the length of the rod 17 is preferably about three times the diameter of the core material 12 of the upright column 11, and the large diameter portion 18 is formed at a distance corresponding to the diameter of the core material 12 from one end in the longitudinal direction. It is best to choose a position close to the center, about the length of . If the rod length and the formation position of the large diameter part are selected in this way, one rod 17 can be used to create two left and right crossbars 14, as shown in Fig. 3.
14 can be joined to the vertical column 11, and as shown in FIG.
By turning the rod rod 17 in the opposite direction to that shown in the figure.
One crosspiece 14 can be joined without exposing it to the outside of the vertical pillar 11. The inner diameter of the hole 20 formed in the cap 19 is made slightly larger than the diameter of the rod 17 so that the cap 19 can swing relative to the rod 17. In this way, the crosspiece 14 itself into which the cap 19 is fitted can be placed against the rod 17 in the hole 2 of the cap 19.
It can be made swingable around the 0 portion.

Next, the procedure for assembling the imitation wooden fence using the rod 17 and the cap 19 will be described.
As shown in FIG. 1, the poles 17, 17 are attached to the upright posts 11 at the ends of the fence.
In this case, the rod 17 is inserted in the direction shown in FIG. 4. Next, the cap 19 is inserted into the core material 12 at the end of the cross bar 14, and the cap 19 is inserted into the rod 17 (FIG. B).
See Fig. 5C]. Next, a rod 17 is inserted from the opposite side into the upright 11 to be joined to the other end of the cross piece 14, and the tip of the rod is inserted into the cap 19 at the other end of the cross piece [see Fig. 5C]. In this case, the rod 17 is inserted in the direction shown in Fig. 3. By joining the cross pieces 14 and the upright 11 one after another in the same manner as above, a wooden fence as shown in Fig. 5D can be assembled. After assembling the wooden fence in this way, the gaps between the notched recesses A, B... of the upright 11 and the cross pieces 14 are filled with joint material to finish it off.

By the way, when assembling a fake wooden fence in this way, if the interval between the two upright posts 11 was too wide than the designed value, there would conventionally be problems such as the crossbars 14 falling off, but with the above structure, crossbar 14
is inserted into the rod rod 17 through a cap 19 fitted therein, and this rod rod 17 is inserted into the core member 12.
Since it is formed sufficiently longer than the diameter of the core material 12 and protrudes sufficiently long from the core material 12 in both directions, there is no risk of it falling off. Moreover, since the crosspiece 14 is supported by the bar rod 17 and not by fitting into the notch recesses A and B of the upright column 11,
Even if the ends of the crossbars 14 are out of the cutout recesses A and B of the upright pillars 11, the strength in the vertical and horizontal directions will not be weakened. Since the central axes of the rods 17 and the crossbars 14 naturally coincide with each other due to the caps 19, it is possible to assemble the artificial wooden fence as designed. Furthermore, when the cap 19 is inserted into the core material at the end of the crosspiece and the rod rod 17 is inserted through the hole 20 of the cap 19, the inner diameter of the hole 20 is made larger than the diameter of the rod rod 17. As shown in FIG. 6, the crosspiece 14 can swing vertically and horizontally about the axis passing through the hole 20 of the cap 19, so even if the fence is curved from side to side, it can be assembled without any difficulty. However, even when assembling a fence on a sloped area, it can be done just as easily. Furthermore, the crosspieces 14 and the vertical posts 11 can be connected by simply inserting the caps 19 fitted into the crosspieces 14 through the rods 17, and there is no need for complicated work such as tightening bolts, so the fence can be assembled quickly. It is something that can be done.

(Effects of the invention) As explained above, according to the artificial wooden fence of the invention, the inner shape of the notch recess is larger than the outer shape of the end of the artificial wooden crosspiece, and the inner diameter of the hole in the cap is larger than that of the artificial wooden crosspiece. Since the diameter is larger than the outside diameter of the rod, the crosspiece is connected to the rod only at one point in the cap hole, and can be swung or rotated around the cap hole, so it can be moved from side to side. It is also possible to assemble fences with curved edges or on sloped areas.

In addition, since the rod is formed sufficiently longer than the diameter of the core material and protrudes sufficiently long from the core material in both directions,
It can be assembled even if the spacing between the pillars is somewhat rough. In addition, all you have to do is insert the rod into the core of the standing pillar and fit the crosspiece into the rod.
The fence can be quickly assembled without the need for complicated work such as bolting.
