DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple structure in which vertical and horizontal ribs are crossed and connected to each other when assembling simple structures such as awnings, greenhouses, garages, and warehouses. The present invention relates to a fastening type connector for assembling, and allows a simple structure to be assembled very simply and easily.

[0002]

2. Description of the Related Art Conventionally, in order to assemble a rib of a greenhouse or the like, a Y-shaped or + -shaped socket-type connector is mainly used. A spiral groove is formed in the socket of this connector, and the spiral part at the end of the bone is screwed and assembled. In some cases, a locking pin is simply locked to a skeleton inserted into an empty socket. Alternatively, a stop pin is elastically provided inside the socket of the connector, and when the bone is inserted into the socket, the stop pin is engaged with the pin hole of the bone. Further, there is a type in which a C-shaped clamp-type iron piece is wrapped around the intersection of the ribs and fastened with a tightening screw. Conventional bone connectors are roughly classified into a socket type and a clamp type.

[0003]

A conventional connector for cross-connecting a bone, particularly a socket-type connector having a Y-shape or a + -shape, is formed by inserting both ends of a bone into a socket. . In this case, the vertical streak and the horizontal streak are cut short to the length of the intersecting interval. As described above, the cut bones have no other use, and the assembled structure has a weak connection strength and easily moves in a gap between the connection parts, and thus lacks stability and cannot withstand strong wind. In addition, when assembling the ribs, the cross connection is considerably time-consuming and requires much time and effort. Further, the position of the intersection of the connector cannot be freely changed.

In the case of a clamp-type connector, the assembly can be cross-connected with a long rib, which has the advantage of increasing the connection strength. However, it takes considerable time to screw many clamps one by one. It is difficult to efficiently assemble the ribs of the structure. In addition, as the metal screw is oxidized and corroded by atmospheric moisture over a long period of time, there is a troublesome problem that the screw cannot be loosened when the bone is dismantled.

SUMMARY OF THE INVENTION An object of the present invention is to solve the conventional problems by assembling a simple structure in a state in which long bones are crossed without using another bolt or fastener. An object of the present invention is to provide a fastening type connector that can be very easily connected by fastening. Further, another object of the present invention is that when assembling a skeleton, the connector positioned at the intersection can be arbitrarily displaced in the left-right or up-down direction according to the assembling conditions of the structure, so that the structure can be easily assembled. It is to provide a connector that can be used. Still another object of the present invention is to provide a fastening connector that can easily assemble and disassemble a robust bone.

[0006]

In order to achieve the above-mentioned object, in the present invention, a fastening structure for a simple structure which is used for crossing and fastening a vertical streak and a horizontal streak of a simple structure is used. The connector is a transverse connecting pipe which is a means for supporting the horizontal streak and which can insert and support the horizontal streak, and a connecting means which is a supporting means for the vertical streak and is formed so as to protrude from the connecting pipe and is clamped to the vertical streak. A holding piece having a substantially U-shape in plan view, a fixing pin formed on the inner surface of the holding piece to be inserted into a pin hole of a vertical streak, and a fastening means for the holding piece, having elasticity capable of being coupled to the holding piece. together comprise a planar substantially C-shaped fastener, prior SL clamping pieces

The grooves are formed to engage each other .

[0007] In order to assemble a simple structure using the fastening type connector for a simple structure according to the present invention, a connecting pipe is fitted to a long and elongated transverse rib next to the structure. The connectors for the number of intersecting vertical ribs are attached to the horizontal ribs in advance. The connector attached to the transverse rib can be displaced in the left-right direction, but does not fall off, so that handling is easy. Next, a large number of vertical streaks are arranged at predetermined target intervals of the structure to be assembled, and the horizontal streaks are horizontally arranged at positions of pin holes at the same height of each vertical streak. The holding piece is brought into contact with the vertical streak so that the fixing pin is inserted into the pin hole of the vertical streak at the intersection. Subsequently, when a fastener having a substantially C shape in a plane is clamped from the opposite side to the vertical streak and coupled to the holding piece, the vertical streak and the horizontal streak can be fastened in a crossed state.

Are firmly fastened at each intersection.

[0011] Thus, the fastening connection at the intersection of the vertical streak and the horizontal streak is completed. Similarly, when each connector is fastened at each intersection, the crossing ribs can be assembled. In order to disassemble the assembled structure, the connector can be easily separated from the longitudinal streak simply by separating the fastener from the holding piece of the connector, so that the structure can be easily disassembled. Since the dismantled bone remains elongate, various other uses are conceivable. Further, by using the connector according to the present invention, when cross-connecting the ribs, anyone can quickly and efficiently assemble the ribs of the structure without using another fastener. .

However, the holding piece can be raised and lowered on the vertical rib at every pin hole interval. The connecting pipe of the connector in the present invention may be a single pipe, or may be of a type in which a pipe is divided and formed, and the divided pipes are joined. In addition, a stop hole is formed in the center of the outer peripheral surface of the connection pipe of the connector, and after the assembly of the structure, a screw is screwed into the stop hole of the connection pipe as necessary to connect the horizontal rib to the connection pipe. May be fixed. In the present invention, the cross-sectional shapes of the connecting tube, the holding piece, and the fastener of the connector are designed according to the cross-sectional shape of the rib.

In the present invention, the connectors can be freely moved in the left-right direction on the horizontal streaks. Therefore, by moving each connector according to the interval between the vertical streaks, the vertical streaks at each intersection. And the transverse rib can be easily fastened. If a stopper hole is formed in the center of the outer peripheral surface of the connecting pipe of the connector, after assembling the structure, if necessary, screw a screw nail into the stopping hole of the connecting pipe to connect the horizontal rib. May be fixed.

In the present invention, the horizontal rib of the structure is inserted and supported in the connecting pipe of the connector, the holding piece of the connector is clamped by the vertical rib, and the fixing pin is a pin of the vertical rib. Since the holding pieces are fastened by elastic fasteners while being inserted and supported in the holes, the vertical and horizontal bones are connected so as to intersect at right angles in the end, and the structure is assembled. Can be done.

The fastening type connector according to the present invention has a very simple structure and is easy to handle. Since the vertical and horizontal bones are fastened by connecting the holding piece and the fastener, the fastening operation is simple and easy. is there. In addition, cross the long vertical and horizontal ribs,
The connecting tube supports the long horizontal rib, and the fixing pin, the holding piece and the fastener support the long vertical rib, so the fastening strength at the intersection is very robust, and it is sufficiently strong against strong winds. It is endurable.
