Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structural aggregate connection fitting that is suitably used as a cross-connection fitting for structural pipes in simple buildings such as vinyl houses.

[Prior Art] Conventionally, in structures using relatively large diameter metal pipes as structural aggregates, such as large vinyl houses, structural aggregate holders that can be opened and closed in a rotational manner have been used as assembly connectors. It is well known that a clamp body consisting of a member and a bolt/nut fastening member is utilized.

The clamp body is firmly attached to the large-diameter pipe by applying its holding part to the pipe and tightening it with bolts and nuts. For example, a dovetail-shaped receiving frame is attached to the flat plate portion, and a sleeve-shaped wedge member for connecting the pipes to be cross-connected is inserted and grips the pipes to firmly connect them.

Such a connector is, for example,
It is stated in the No. According to this publication, such a dovetail-shaped receiving frame is firmly integrated with the above-mentioned right-angled plate portion by driving four rivets into the flat plate portion thereof in close contact with the rectangular plate portion.

[Problems to be solved by the invention] Such a connector is convenient because even if the diameter of the pipes to be connected changes, a fitting corresponding to the diameter can be selected and used, but it is difficult to connect the dovetail receiving frame and the fitting. It was difficult to do so, and the bonding strength was not satisfactory.

That is, an object of the present invention is to overcome the disadvantages of the above-mentioned coupling operations, and to provide a combination coupling fitting that can be selectively used depending on the diameter of the pipes to be cross-connected and has excellent coupling strength. It's about doing.

[Means for Solving the Problems] In order to achieve the above object, the inventor of the present invention has conducted repeated research into prototyping, and as a result, has found a desirable connecting fitting.

According to the present invention, in a connecting device consisting of a structural aggregate holding clamp body that can be opened and closed in a rotational manner and a bolt/nut fastening member, one part of the clamp body that is connected in a rotational manner is connected at right angles. A rectangular plate body longer than the width of the plate part is integrally attached to at least one of the formed plate parts, and in the vicinity of both edges of the opposing sides protruding from the plate part of the plate body,
An elongated through hole and a bolt insertion through hole are respectively formed parallel to the side, which can receive the U-shaped cross-sectional plate part of the cross-pipe pressing and gripping member, and the gripping member is a plate body with an Ω-shaped cross-sectional shape. One of the overhanging flat plate parts is formed with an engaging part that is bent into a U-shaped cross section, and the other overhanging flat plate part is formed with through holes for bolt insertion, thereby creating a combined structural aggregate connection. hardware is provided.

The clamp body in the present invention constitutes the main part of the coupling device, and consists of two parts that can be opened and closed in a rotational manner that is applied so as to embrace the structural aggregate. The ends are fastened with bolts and nuts, preferably with bolt heads pivotally attached to either end. One piece of the rotationally connected clamp body is formed with an adjacent flat plate part bent at right angles, and these two plate parts can be used to connect, for example, other intersecting pipes or other objects. It is used to perform work to connect the members to be connected.

In the present invention, a rectangular plate having a length greater than the width of the plate is firmly attached to the plate using, for example, four rivets, and the integrated plate protrudes from the flat plate. On both opposing edges, an elongated through hole parallel to that side is formed on one side, and a through hole for bolt insertion is formed on the other side. One or two bolt holes are usually sufficient. On the other hand, the cross-pipe pressing and gripping member combined with the plate is a plate with an Ω-shaped cross section, and one of the overhanging plates is further bent into a U-shaped cross section, and this U-shaped part is hooked into the elongated through hole. It is formed so that it can be inserted. The other overhanging plate has the above-mentioned bolt insertion through-holes drilled at positions that match those of the rectangular plate, and after inserting the connecting pipe, it can be gripped with force by tightening the bolts and nuts. It is something.

[Function] The metal fittings of the present invention have high usability because the press gripping member can be selected according to the connecting pipe, and the connection strength is extremely strong, so it can be used for large houses such as large houses. It has excellent usability as a connector for structural materials that require

[Example] Next, the example shown in the accompanying drawings will be described in more detail.

FIG. 1 is a front view of the connecting fitting according to the present invention in use, viewed diagonally from above.

FIG. 2 is a perspective view showing the three main parts of the metal fitting separately, to explain them.

In the figure, a structural aggregate holding clamp body 1 can be rotatably opened and closed by a shaft 2. As shown in FIG. Thus, through-holes 4, 4, . The head of the bolt 5 is rotatably held by a shaft 2'. The rectangular plate 6 to be riveted in the above-mentioned through-holes has through-holes 4', 4', .
A through hole 8 for inserting a bolt is formed in the edge portion facing the . This plate body 6 is joined to the plate portion 3 and is integrally riveted with studs 9, 9, . . . as shown in FIG. This clamp body is firmly attached to the pipe by rotatingly holding the large pipe _P1 , screwing the nut 10 onto the bolt 5, and tightening it through the washer 11. On the other hand, the cross-pipe pressing and gripping member 12 with an Ω-shaped cross section to be combined with this has one end further bent into a U-shaped cross section, and the bent portion 14 is passed through the elongated through hole 7, and the side thereof is bent to have a U-shaped cross section. The edges are engaged so as to protrude outward from the edges of the plate body 6. Next, the second pipe P ₂ to be connected to the Ω-shaped curved portion 13 is sandwiched, and the bolt 15 is inserted into the through hole 8' of the other end edge and the through hole 8 of the plate body 6.
The pipe is firmly integrated into the connector by threading it through the pipe and tightening with a nut (not shown), so that the two pipes are stably cross-connected.

[Effects of the invention] The connecting fitting of the present invention has much stronger connection strength than conventional ones, and has extremely high practical value as a fitting for connecting structural aggregates of large houses.
