Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a practically improved cross-connection fitting between the structural aggregate of a simple vinyl house and a groove frame for securing a vinyl sheet.

[Prior art] Conventionally, a metal plate body with a U-shaped cross section having cut holes for inserting and abutting simple house structural aggregates on the overhanging side panels, and a metal plate with a U-shaped cross section inscribed inside the plate body. BACKGROUND OF THE INVENTION Cross-connections between structural aggregates and groove frames consisting of wedge-shaped wedges are known. In this combination fitting, after a structural aggregate and a groove frame are applied to a metal plate body, a wedge is driven into the gap between the two to fix the two.The stronger the wedge is driven, the more the metal plate The curved surfaces of the edges of the side plates of the body are pushed outward by the receiving groove-forming shoulders of the groove frame, and the relative attachment position of the frame to the pipe changes, making the fixation rather unstable. I had the inconvenience of becoming

[Problem that the invention attempts to solve]

Therefore, an object of the present invention is to provide a structure in which the seat locking groove frame is used as a structural aggregate without the above-mentioned disadvantages.
An object of the present invention is to provide an improved combination cross-connection fitting that can be stably and firmly connected.

[Means for solving problems]

The inventors of the present invention conducted many trial production experiments on means for achieving the above object, and as a result, they discovered a practically desirable and improved metal fitting.

That is, the present invention is a connector in which a metal plate with a U-shaped cross section is combined with a metal plate wedge with a U-shaped cross section applied to the inside thereof, and the opposite side plates of the plate are combined. The portions are formed into horizontally curved surfaces that are slightly bent inward from each other so that both edges thereof can engage the synthetic resin sheet retaining groove frame, and each edge of the both side plate portions A notch is formed in which the simple house structure aggregate pipe cut upward from the center of the section is applied to the opposite side plates, and each of the four leg-shaped side plates formed separately by such a cut is The present invention provides a cross-connection fitting between the structural aggregate and the groove frame, in which receiving members for receiving both edges of the wedge are integrally formed at predetermined locations on the inside.

The combination connecting fitting of the present invention is characterized by integrally forming receiving members for receiving both leg edges of the wedge to be driven in on the inside of the four side plate parts of the metal plate body, and the foot plate of the wedge. This is based on the discovery that the above-mentioned disadvantages can be effectively overcome by a receiving member that restrains.

[Action/Effect]

The metal fitting of the present invention does not substantially push open the side plates of the metal plate even if the wedge is driven strongly.
The groove frames can be stably and firmly connected.

〔Example〕

Next, the connecting fitting of the present invention will be explained in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an example of the cross-connection fitting of the present invention in use, and for ease of understanding, structural aggregates (pipes) are shown with imaginary lines.

In the figure, a metal plate 1 having a U-shaped cross section has edges 2, 2 of opposing side plates bent slightly inward to form a curved surface.
It is configured to be able to lock a groove frame F for locking a synthetic resin sheet stretched over a simple vinyl house. This curved surface portion is formed with reinforcing ribs projecting outward in the direction of the curve so as to increase the strength of the curve. Further, cut holes 3 are formed in both side plate portions of the metal plate body 1 by cutting out substantially the center of each width in the direction of extension, into which the house structural aggregate pipe P is applied. The round pipe P (imaginary line) in the figure is inserted into the notch hole 3 of both side plate parts and received in a bridging manner. Both cut holes 3
The terminal end portion of is formed in a shape (semicircular) that matches the cross-sectional outline of the abutting pipe so that the pipe P is abutted in a fitting manner and is effectively fixed. Further, each of the four side plates formed separately by the cut is provided with a receiving member 5 for receiving both end edges of a wedge 4 having a U-shaped cross section applied to the inner side thereof. The wedge receiving member 5 may be integrally formed so as to be able to restrain the foot plate of the wedge at a predetermined position inside each side plate, but in practical use it is formed by driving a predetermined part of the side plate inward. preferred.

On the other hand, the wedge 4 is formed so that the height of both foot plates is slightly inclined from one side to the other,
Has a wedge function. Therefore, considering its wedge function, the wedge receiving member 5 is
Of course, the wedges should be formed at appropriate positions depending on the driving direction of the wedge.

In the cross-connecting fitting of the present invention, first, the structural aggregate pipe P is brought into contact with both cut holes 3 of the side plates of the plate body 1, and then the groove frame F is attached to the corresponding curved edges 2 of the side plates, Rotate and insert from the gap 2,
Both shoulder portions forming the receiving groove of the frame are engaged with the curved edge portions 2, 2. In this way, when the pipe P and the groove frame F are brought into contact and engaged with each other, by pushing the wedge 4 into the gap in a predetermined direction and pressing, the two can be easily and firmly attached without pushing the opposite side plates apart. can be cross-linked.
