Description

  The present invention relates to a bundling bracket for simply and firmly binding a crossing portion between mutually contacting pipes.

For example, a commercial product for a temporary scaffold shown in FIG. 17 has conventionally been used as a cross-section binding metal fitting for pipes for assembling a fence or a greenhouse skeleton.

  This is composed of first and second clamps (C) and (C) which are assembled and integrated in a back-to-back orthogonal state via a plurality of fixing pins (1). ) And (C) surround the vertical pipe (Y) and the horizontal pipe (X), respectively.

  That is, reference numerals (2) and (3) in the figure are a pair of holding plates that form each of the first and second clamps (C) and (C), and are plastically processed into an arc shape facing the steel plate, The base ends of both the holding plates (2) and (3) are pivotally attached to each other by a penetrating pin (4).

  In addition, the head of the bolt (6) is turned up and down at the tip of one holding plate (2) via a separate short penetrating pin (5) parallel to the penetrating pin (4). A bifurcated fork-shaped nut receiving seat (7) sandwiching the screw shaft portion of the bolt (6) protrudes from the corresponding tip of the other holding plate (3). Yes.

  Then, each of the vertical pipe (Y) and the horizontal pipe (X) is surrounded by both the holding plates (2) and (3), and the nut (8) screwed to the bolt (6) is tightened. Thus, the intersection of the vertical pipe (Y) and the horizontal pipe (X) is bundled.

  However, in such a configuration of the binding metal fittings, the pair of holding plates (2) and (3) that form each of the first and second clamps (C) and (C) are not only plastic processed products from steel plates, Since a plurality of separate penetrating pins (4), (5) and bolts (6) are also required, the overall weight is larger than the applicable pipe (Y) (X). The mass production effect cannot be expected.

  In addition, the first and second clamps (C) and (C) of the above-described binding metal are interposed at the intersection of the vertical pipe (Y) and the horizontal pipe (X), and surround the pipe (Y) and (X) separately. It is a heavy rigid product. Therefore, even if each pipe (Y) (X) is held by the opposing circular arc surfaces of both holding plates (2) and (3), and even if the nut (8) is strongly tightened at the beginning of use, External forces such as vibration and impact received during use cannot be absorbed, and the vertical pipe (Y) may be slid down to cause misalignment of the crossing portion.

  In addition, when the crossing portion of the vertical pipe (Y) and the horizontal pipe (X) is used, the tip of the bolt (6) and the tip of the bifurcated fork-shaped nut seat (7) protrude sharply. Because it will be exposed, it is extremely dangerous, and a special flexible vinyl cover (9) is also prepared, and it can be safely put on the first and second clamps (C) and (C). Must be covered.

  The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, a single round metal wire that can be wound around a crossing portion where a vertical pipe and a horizontal pipe are in contact with each other is used. Consisting of

Corners where the male screw is carved to detach one end of the round wire, also round wire-like hook bent in disconnecting the other end of the nut seat, intersects with the vertical pipe and horizontal pipes In the positional relationship retracted to each other , the above-mentioned vertical pipe and horizontal pipe are tightened by tightening a nut that has been screwed onto the male screw in advance so that it cannot be removed. as unity brackets that tie the intersection,

  By bending the remaining intermediate portion of the round wire material alternately in the vertical and horizontal directions, a pair of substantially parallel first and second arc holding surfaces wound around the vertical pipe and a pair of substantially parallel third wires wound around the horizontal pipe. While forming a series of 4 arc holding surfaces,

A number of striations in which a rough surface for preventing slippage with the corresponding pipes is depressed at a certain depth (g) from the circumferential surface of the round wire rod to a total of four locations of the first to fourth arc holding surfaces. And is pressed into an arrangement relationship substantially parallel to the diameter line of the round wire .

According to the above configuration of the first aspect, the bundling metal fitting is remarkably light as a series of products bent from a single metal round wire, combined with its simple necessary configuration, and exhibits the mass production effect to the maximum. Even if it is used, it is sufficient to rotate one nut, and the crossing portion between the vertical pipe and the horizontal pipe can be quickly and lightly bound, and the bundling operation can be performed.

In addition, during the use of the above-described binding metal fittings, the male screw engraved at one end of the metal round wire and the hook-shaped nut receiving seat bent at the other end of the separation include a vertical pipe and a horizontal pipe. In the positional relationship retracted to the intersecting corners of the corners, they are kept in their locked state and are fastened by nuts, so the first to fourth arc holding surfaces that wrap around the vertical and horizontal pipes are literally Combined with the curved shape of the arc, safety can be maintained even in the exposed state, and it is not necessary to cover the cover by applying a special vinyl cover or the like.

In addition, the first to fourth arc holding surfaces that are continuously bent from one metal round wire wrap around each of the vertical and horizontal pipes in a superimposed manner, so that the pulling resistance force and the metal round wire itself Due to this bending action, there is no risk of rattling or relaxation, and the crossing portion of the vertical pipe and the horizontal pipe can be maintained in a stable and firm state.

Furthermore, the first to fourth arc holding surfaces have a rough surface for preventing slippage with a vertical pipe or a horizontal pipe, in particular, as a large number of striations that are depressed by a certain depth from the circumferential surface of the metal round wire. Because it is pressed almost in parallel with the diameter line of the wire, in other words, it is pressed into an arrangement relationship that is almost perpendicular to the tangent line between the metal round wire and each pipe, so the unexpected sliding action of the binding hardware In addition, it can provide effective resistance against the idling action, and it can be bound and bonded without causing misalignment of the crossing part even if it receives external forces such as vibration and shock repeatedly during use. It is done.

Hereinafter, the specific configuration of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 16 show the binding metal fitting (A1) of the present invention and the state of use thereof, which are a vertical pipe (Y) and a horizontal pipe ( It consists of one steel wire or other metal round wire (M) with a required length that can be wound around the crossing portion in contact with X).

In this regard, in the example shown in the figure, the vertical pipe (Y) and the horizontal pipe (X) are composed of metal pipes (iron pipes) having the same diameter (D) of about 48.6 mm for assembling the fence (F). Further, as the metal round wire (M), a carbon steel wire having a diameter (d) of about 5.8 mm and high in tensile strength is employed.

And the binding metal fitting (A1) of the present invention is repeatedly bent vertically and horizontally from such a single metal round wire (M) as shown in FIGS. ) And a pair of substantially parallel first and second arc holding surfaces (11) and (12) that wrap around the horizontal pipe (X) and a pair of substantially parallel third and fourth arc holding surfaces (13) that wrap around the horizontal pipe (X) ( 14) and a series of shapes.

That is, the first circular arc holding surface (11) and the horizontal pipe (X) wound around the vertical pipe (Y) in order from either one of the cut ends of the metal round wire (M) toward the other. ) The third arc holding surface (13) wound around the vertical pipe (Y), the second arc holding surface (12) wrapped around the vertical pipe (Y), and the fourth arc holding surface (14) wrapped around the horizontal pipe (X) again. And a pair of first and second arc-holding surfaces (11) and (12) that are substantially parallel to the ridge are also substantially parallel to the circumferential surface of the vertical pipe (Y). A pair of the third and fourth arc holding surfaces (13) and (14) can hold the circumferential surface of the horizontal pipe (X) in a superimposed manner.

Further, a male screw (15) is engraved on one end of the metal round wire (M), and a nut (16) with a hook is preliminarily screwed onto the male screw (15) so as not to fall off. Has been. The hooked nut (16) is kept in a state where it is prevented from coming off from the male screw (15) by plastic deformation at one end of the separation or partial crushing of the male screw (15).

On the other hand, the other end of the metal round wire (M) is bent into a series of hooks as a nut receiving seat (17), and is removably locked to the male screw (15) at the one end. By doing so, it can function as a washer for the hooked nut (16).

Further, (18) and (19) wind around the first and second arc holding surfaces (11) and (12) wound around the vertical pipe (Y) of the metal round wire rod (M), and also around the horizontal pipe (X). Anti-slipping rough surfaces engraved in a total of four places with the third and fourth arc holding surfaces (13) and (14), and slipping with the corresponding pipes (Y) and (X) Stops. The rough surfaces (18) and (19) are located on the tangent line between the vertical pipe (Y) or the horizontal pipe (X) and the metal round wire (M), and the first to fourth arc holding surfaces (11 Needless to say, it is engraved on the concave curved surface of (12), (13) and (14).

Such anti-slipping rough surfaces (18) and (19) with the pipes (X) and (Y) have a certain depth from the circumferential surface of the metal round wire (M), as shown in FIGS. (G) As a large number of depressions that are depressed, the arrangement relationship is substantially parallel to the diameter line (OO) of the round wire (M), in other words, the round wire (M) and each pipe (Y) (X ) And tangent to the arrangement of the relationship of being almost orthogonal.

As shown in FIG. 11, such a large number of striations are formed on the first to fourth arc holding surfaces (11), (12), (13), and (14) of the metal round wire (M) bent first, Holding the first to fourth arcs by sandwiching the male mold (20) and the female mold (21) from the inside and outside directions and pressurizing the corresponding convex blade (22) of the male mold (20) from the inside. The concave surface of the surfaces (11), (12), (13), and (14) can be surely cut as if it were damaged.

Since the binding metal fitting (A1) of the present invention has the above-described configuration, the hook-shaped nut receiving seat (17) located at the other end of the metal round wire (M) is left in use. In the open state before being locked to the male screw (15) at one end of the cut, the metal round wire (M) is wound so as to be inserted into the intersection of the vertical pipe (Y) and the horizontal pipe (X) and The nut (16) is closed by locking the nut seat (17) to the screw (15), and the nut (16) with a hook is tightened with a rotating tool (not shown) such as a ratchet wrench or spanner. What is necessary is just to bind tightly the crossing part of a vertical pipe (Y) and a horizontal pipe (X) like FIGS.

FIG. 16 illustrates the assembled state of the fences (F) bound in this way, but the binding metal fitting (A1) of the present invention is a first bent and shaped from a single metal round wire (M). Since it has 1-4 arc holding surfaces (11), (12), (13), and (14), it intersects perpendicularly with a vertical vertical pipe (Y) standing up from the ground and a horizontal horizontal pipe (X). Not only that, but also the non-orthogonal crossing portion of the vertical pipe (Y) standing upright from the ground and the horizontal horizontal pipe (X) can be firmly bound and bound without any trouble.

In any case, since only one of the hooked nuts (16) needs to be rotated, the binding work can be performed quickly and easily by anyone, and the binding metal fitting (A1) itself is one piece. As a lightweight product made of a metal round wire (M), a pair of first and second arc-holding surfaces (11) and (12) wound around the vertical pipe (Y) and a third wound around the horizontal pipe (X) In each of the four arc-holding surfaces (13) and (14), the anti-slip rough surfaces (18) and (19) are recessed by a certain depth (g) from the circumferential surface of the metal round wire (M). Since it is pressed into a large number of striations and in an arrangement relationship substantially parallel to the diameter line (OO) of the round wire (M), during use in a bundled state as shown in FIGS. Should it be subjected to external forces such as vibrations or shocks, it will cross, especially as it slides down the vertical pipe (Y). There is no risk of causing the position deviation of.

Furthermore, since the binding metal fitting (A1) of the present invention is bent in series from one metal round wire (M), for example, it receives an external force in a direction in which the vertical pipe (Y) and the horizontal pipe (X) are separated. In this case, the first and second arc holding surfaces (11) and (12) wound around the vertical pipe (Y), and the third and fourth arc holding surfaces (13) around the horizontal pipe (X) ( 14) will pull the remaining other, and in combination with the bending action of the metal round wire (M) itself, there is no risk of rattling or relaxation, and the vertical pipe (Y ) And the horizontal pipe (X) can be maintained in a stable and firm state.

When the binding metal fitting (A1) is in use, the first to fourth arc-holding surfaces (11), (12), (13), and (14) are literally in the form of arcs, and the vertical pipe (Y) and the horizontal pipe (X). The male screw (15) forming one end of the metal round wire (M) and the remaining nut receiving base (17) forming the other end are shown in FIGS. Thus, since the vertical pipe (Y) and the horizontal pipe (X) are in a positional relationship retracted to the intersecting corner, and are fastened by the hooked nut (16), these are the vertical pipe (Y) And it does not protrude sharply from the horizontal pipe (X), and safety and makeup effects can be secured as it is.

12 to 16, the vertical pipe (Y) and the horizontal pipe (X) having the same diameter (D) are illustrated, but the vertical pipe (Y) having a different diameter (D) is illustrated. For bundling the cross section with the horizontal pipe (X), the arc-holding surfaces (11), (12), (13), and (14) corresponding to this are folded to form a bundling bracket that can be used without any trouble. be able to.

In the case of the illustrated embodiment, the vertical pipe (Y) stands upright from the ground for assembly of the fence (F). For example, as seen in a skeleton of a greenhouse, The present invention can also be used as it is as a cross-section binding metal fitting between the vertical pipe (Y) and the horizontal pipe (X) that intersect on the surface.

Further, the binding metal fitting of the present invention can be applied not only to metal pipes but also to synthetic resin pipes and the crossing portion of the synthetic resin pipe and the metal pipe. ) (12) (13) (14) It can be said that the anti-slip rough surfaces (18) and (19) pressed at a total of four locations work effectively.
