Description

[Detailed explanation of the invention] <Industrial application field> This invention is for transporting and transporting the vertical and horizontal members of fences manufactured in factories using reinforced concrete, synthetic resin, etc. to sites such as parks, amusement parks, and ranches. This invention relates to a connecting device for vertical and horizontal members of an assembled fence for easy assembly into a fence.

<Prior art> The vertical and horizontal members of an assembled fence are molded from reinforced concrete, synthetic resin, etc. to simulate a tree in appearance, and then transported to the site of use and assembled as shown in Figure 1.

Figures 6, 7, and 8 show the vertical members V and horizontal members H of a conventional fence.
Fig. 6 shows the connection state of the left and right cross members H, H, which are simply inserted into the horizontal thick through hole of the vertical member V. Even with this, the end of each horizontal member will fit into the horizontal through hole of the vertical member by about half the thickness of the vertical member, so it will not fall out as it is. However, if the vertical member V descends or slopes due to ground subsidence or the like, the horizontal member H easily falls off the vertical member. A further problem is that in order to provide a through hole for the horizontal member H to enter as shown in Figure 6, the reinforcing bars 1 in the vertical members V must be placed close to the surface, making the reinforcing bars 1 susceptible to corrosion. .

In order to avoid this drawback, in Fig. 7, instead of making a large through hole in the vertical member V, a mortar-shaped hole is provided on both sides of the vertical member into which the tapered tip of the horizontal member H enters, and both of the mortar-shaped holes are provided on both sides of the vertical member. The reinforcing bars 2 of the horizontal members are connected through narrow holes through which the reinforcing bars 2 pass through, and the tips of the left and right horizontal members and the reinforcing bars protruding from these tips are inserted, and the reinforcing bars 2 of the horizontal members 2,
It pits like-minded people against each other.

Although this allows the reinforcing bars 1 in the vertical members to be located inside the vertical members, the drawbacks that the vertical members fall due to ground subsidence or the like and the horizontal members fall out due to inclination still remain.

Figure 8 shows that in order to completely prevent the horizontal members V from falling out, short connecting reinforcing bars 3 protruding from each side of the vertical members are passed through thin horizontal through holes made in the vertical members V, and A reinforcing bar 2 protruding from the tip of the material H is connected to each protruding portion of the connecting reinforcing bar 3 by welding W. This eliminated the fear of it falling out, but a welding machine was required for assembly, and the gaps between each side of the vertical member and the tip of each cross member were filled with a large amount of mortar M to improve the appearance. It takes a lot of effort to protect the reinforcing bar welds from corrosion, and even if the appearance is made with mortar, the surface of the mortar layer and the tree-like surface of the vertical and horizontal members are significantly different in appearance. The problem is that it looks unnatural and feels strange.

The connection method shown in FIG. 8 follows the connection of reinforced concrete structures such as buildings. However, the connection between the vertical and horizontal members of a fence does not require as much strength as the connection of a building. And depending on the length of the fence, there are many connections.

<Problems to be solved by the invention> Therefore, even if the connection strength is not very strong, the device for connecting the vertical and horizontal members of an assembled fence can be used to prevent the vertical members from descending to a certain extent due to ground subsidence, etc. The connection with the cross member will not come off even if it is tilted, and equipment such as welding,
There is a need for something that can be easily assembled into a natural-looking fence on site without requiring any skill or handling of mortar.

<Means for solving the problem> The present invention is intended to solve the above problem,
As a connection device for the vertical members and the horizontal members of the assembled fence, one end of a joint rod for connecting the horizontal members is embedded so as to be swingable at the position where the horizontal members of the vertical members are connected, and the other end of the joint rod is connected to the The U-shaped folding connector that protrudes outside the vertical member is sandwiched between the open ends, and the other end of the joint rod is pivotally connected to the folding connector using a stop shaft, and the end of the horizontal member to be connected to the vertical member is A connecting tube into which the folded connector enters is buried, and when connecting the vertical members and the horizontal members, a connecting pin is passed through a hole that is opened so as to pass through the horizontal member and the connecting tube in series, It is characterized in that it passes through the folded end of the folded connector that protrudes into the connecting tube.

<Example> In Figs. 2 to 5, 11 is a joint rod;
2 is an enlarged portion provided at one end, 13 is a U-shaped folding connector, 14 is a stop shaft, 15 is a connecting tube, and 16 is a connecting pin, all of which are made of metal.
13a and 13a are the bifurcated pieces of the folded connector which sandwich the other end of the joint rod and are pivoted thereto by a stop shaft 14, and 13b indicates the folded end thereof.

In order to embed the enlarged part 12 at one end of the joint rod 11 in a swingable manner at the connection position of the horizontal member of the vertical member V, a socket 17 is formed by press-forming the enlarged part 12 from steel material.
It is wrapped and held in a ball joint style.

Then, when forming the vertical member V at the factory, the socket 17 is fixed by welding to the reinforcing bar 1 arranged in the vertical member mold, and the joint rod 11 is positioned at the connection position with the cross member. Then, the vertical members are formed in concrete or plastic.

Similarly, when forming the cross member H, it is placed in a cross member forming mold so that the connecting tube 15 is buried in the end of the cross member, and is welded to the reinforcing bars 2 arranged in the mold. The cross members are made of concrete or plastic. In addition, cover or fill the mold so that the concrete or plastic poured into the mold does not enter the gap between the socket 17 and the enlarged portion 12 or the inside of the connecting tube 15.

Further, as shown in the figure, the end portion 18 of the cross member in which the connecting tube 15 is buried is tapered, and the end portion 18 of the cross member is shallowly and loosely received at the connection position with the cross member. A recess 19 is provided, the other end of the joint rod 11 is located in the recess 19, and the folded connector 13, which is pivotally attached to the other end of the joint rod with a stop shaft 14, is inserted into the recess 19.
It is preferable to place it so that it protrudes outside.

Now, in the embodiment shown in Figs. 2 and 3, a socket 17 is buried in one side of the vertical member V to which the horizontal member is to be connected, and a stop shaft is installed at the other end of the joint rod 11 protruding from the socket. 14 is inserted into the connecting tube 15 buried in the end of the cross member H,

Insert the connecting pin 16 into the connecting tube, fold the connecting pin 16 inside the connecting tube, and connect the connecting pin 13 to the folded end 13b of the connecting tool 13.
Each end of the cross member is connected to each side of the stringer by threading it through the ends.

Further, in the embodiment shown in FIGS. 4 and 5, the enlarged portions 12, 12 at each end of the two joint rods 11, 11 are held at each end of one cylindrical socket 17.

Therefore, by embedding this socket 17 in the vertical member V as described above, the folded connector 13 is connected by the stop shaft 14 to the other end of each joint rod 11, 11 protruding from each end of the socket. , 13 are embedded in the ends of the respective cross members H and inserted into the connecting tube 15, and the connecting pins 16 are inserted in series into each cross member and the connecting tube. Two cross members can be connected at a location. In order to restrict the movable range of the enlarged portions 12 held at each end of the socket, a pin 17' may be inserted through the center of the socket to partition the inside.

In each of the embodiments, as described above, a recess 19 is provided in the longitudinal member at the position where the cross member is connected, and the tapered end 18 of the cross member is inserted loosely into the recess 19 to connect the longitudinal member and the cross member. Since the joint rod 11 and the folded connector 13 are not visible from the outside, the appearance is good.

Further, the hole 20 in the cross member into which the connecting pin 16 is inserted may be filled with mortar. Since this hole is small in diameter, it can be filled with mortar without damaging the appearance of the crosspiece.

<Effects of the invention> According to the invention, the folded connectors 13 protruding from the cross member connection positions of the vertical members V are inserted into the connecting tubes 15 buried in each end of the cross members, and the cross members and the connecting tubes are connected. It is possible to easily connect the vertical members and the horizontal members by passing a connecting pin that passes through them in series into the folded end 13b of the folded connector in the connecting cylinder, and furthermore, the ends of the horizontal members are separated from the vertical members. It can prevent it from coming off. and,
The joint rod 11 with the folded connector connected to the other end can be swung relative to the vertical member by the enlarged portion 12 at one end, and the other end of the joint rod and the folded connector 13 are pivotally connected by a stop shaft 14. Because of this, even if the vertical members fall or tilt due to ground subsidence, they will maintain their connection without any problems, and when installing on uneven ground, the vertical members should be erected perpendicular to the ground, and the horizontal members It is convenient because it can be tilted according to the undulation of the ground.
