Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for integrally connecting constituent members of a large air conditioner, such as a main body and a fan casing, a coil casing, a filter casing, etc.

(Prior Art) When assembling a large air conditioner, generally the rectangular cylindrical structural members to be connected are brought together with their respective outer flanges and tightly fastened together with bolts and nuts.

(Problem to be solved by the invention) However, when joining flanges by butting them together, it is extremely difficult to match the joining holes provided on both flanges, especially in the case of large members, and it is difficult to connect the joining holes provided in both flanges. When such a bolt is used, it takes a lot of effort and time to finely adjust and center it, and there are many difficulties in inserting the bolt due to mismatching of the coupling holes.

(Means for Solving the Problems) In view of the above, the present invention simplifies the positioning of structural members to be connected when butting them together, and provides at least a long angle of each connecting end of the double-sided cylindrical members to be connected. Positioning metal fittings each having a mountain-shaped unevenness formed on the periphery of two consecutive sides with tapered edges on opposing surfaces are each fixed at a predetermined position where the mountain-shaped unevenness is fitted and matched with the other positioning metal fitting to be connected. It is characterized by

(Function) In the present invention, the connection ends of the two component members 1, 1 to be connected are brought close to each other, facing each other, and when the flanges 2, 2 are butted against each other during the connection work, at least two sides of the rectangular periphery that are connected at right angles. Due to the fitting of the positioning metal fittings 4 fixed opposite to the members 1, even if there is a deviation in the positional relationship between the flanges 2 when they are close to each other, the deviations are corrected according to the taper of the chevron-shaped unevenness and the members 1 fit together. , 1 are overlapped in an accurate positional relationship, and the cores of the coupling holes 3 on both flange surfaces match, thus facilitating coupling with bolts and nuts and improving work efficiency. Since it is provided on at least two perpendicular sides of the rectangular periphery, the upper and lower sides of the connecting ends are
Left and right deviations can be automatically corrected.

(Example) In the drawings, reference numerals 1 and 1 indicate structural members having a rectangular cross section to be connected to each other in an air conditioner, and a flange 2 is formed on the inner circumferential surface of the connection end of each member, and a large number of connecting parts are formed on the inner peripheral surface of each member. 3 was installed.

Positioning metal fittings 4 were fixed to the connecting ends of each member 1, 1 so as to face each other at least on two perpendicular sides of the rectangular periphery thereof.

The positioning fitting 4 is formed with a mountain-shaped unevenness 5 having a triangular or trapezoidal tapered edge on its opposing surface,
When the projections and depressions 5 fit into and match the projections and depressions 5 of the positioning metal fitting 4 fixed to the other member 1 to be connected, the projections and depressions 5 are placed in a predetermined position so that the flanges 2, 2 are in an accurate overlapping relationship. stick.

In the illustrated example, positioning metal fittings 4 are fixed at predetermined positions on three sides of the rectangular periphery of the member 1 to further improve the accuracy of the centering configuration.

In the above embodiment, the connecting flange 2 is formed on the inner side of the periphery, so that the connection work is performed inside the rectangular component 1, but when the flange 2 is formed on the outside as shown in FIG. are provided at predetermined positions inside each member 1.

(Effect of the invention) According to the invention, the positioning metal fittings are connected at right angles to each other at least on the rectangular member, with the connecting ends of the two component members to be connected facing each other in a predetermined positional relationship.
Each side of the fitting is provided with a chevron-shaped unevenness with a tapered edge on the opposing surface, so when the connecting ends of both members are butted together, it is automatically fitted with the uneven part of the opposing positioning fitting. centering is performed,
The flanges of both parts can be easily butted together in an accurate overlapping relationship, and the tightening work with bolts and nuts can then be easily performed, speeding up the connection work and improving work efficiency. This integral connection has the effect of preventing damage caused by vibration.
