2. Description of the Related Art Conventionally, a concrete block is generally known as a block used when receiving an outdoor unit of an air conditioner and installing the outdoor unit. However, the concrete block is heavy, inconvenient to handle, and costly. Due to the high cost, lightweight, easy-to-handle and inexpensive blocks made of synthetic resin have recently been used.

In this synthetic resin block, a groove for engaging the head of a bolt for connecting and fixing the outdoor unit of the air conditioner is formed on the upper surface of the block in the longitudinal direction from the longitudinal end of the block. When installing the air conditioner outdoor unit, engage the bolt head with the groove and insert the male screw shaft of the bolt protruding upward from the groove into the hole of the bracket at the bottom of the air conditioner outdoor unit. A nut is screwed onto the shaft from above and tightened.

[0004]

However, bolts and nuts are required to install an air conditioner outdoor unit using the above-mentioned synthetic resin block, and tightening of the nut with respect to the male screw shaft portion of the bolt is troublesome, and the work is difficult. There was a problem of poor sex.

The present invention solves such a problem, and an object thereof is to improve the workability of installing an air conditioner outdoor unit.

[0006]

In order to solve this problem, the present invention is directed to the upper surface of a receiving portion 6 of a synthetic resin block 1 having a substantially rectangular planar shape and a hollow interior so as to face the longitudinal direction of the block 1. Groove portion 9 is formed, and a pair of left and right blocks 1 is formed.
The lower left and right sides of the air conditioner outdoor unit 5 are placed on the receiving part 6 of the air conditioner, and the bracket 7 at the lower end of the air conditioner outdoor unit 5 is aligned with the groove 9 on the upper surface of the receiving part 6 from above the bracket 7. The shaft portion 8a of the rivet 8 is attached to the groove portion 9
Then, the protrusions 8c, 8c provided at the lower end of the shaft 8a projecting downward from the groove 9 by being inserted into the groove 9 are oriented in a direction orthogonal to the longitudinal direction of the groove 9, and the protrusion 8c, 8c is configured to be able to contact the lower end of the groove portion 9.

[0007]

With this structure, the shaft portion 8a of the rivet 8 is inserted into the groove portion 9 on the upper surface of the receiving portion 6 of the block 1 from above the bracket 7 at the lower end of the air conditioner outdoor unit 5 and then rotated to lower the lower end portion of the shaft portion 8a. The convex portions 8c, 8c provided on the ridge 8 are oriented in a direction orthogonal to the lengthwise direction of the groove portion 9, and when a force acts to pull the rivet 8 upward,
Since the c and 8c come into contact with the lower end of the groove portion 9 to prevent the rivet 8 from coming off, the air conditioner outdoor unit can be installed with good workability and reliably without using the conventional bolts and nuts.
