本発明は補強芯で補強された合成樹脂製パレツ

合成樹脂製パレツトに剛性を付与するために鉄

げられ、全体の成形収縮が不均一となり、合成樹
脂製パレツトに歪が生じる欠点があつた。 In order to give rigidity to synthetic resin pallets, they are reinforced with reinforcing cores such as iron pipes or iron bars, but synthetic resin pallets that are reinforced with reinforcing cores have a tendency for the synthetic resin to shrink inside when molding shrinks. The molding shrinkage in the longitudinal direction of the reinforcing core around the reinforcing core is impeded, and the entire molding shrinkage becomes uneven, causing distortion in the synthetic resin pallet. There were flaws.
本発明者等は、補強芯で補強されているにもか

樹脂製パレツトについて研究を進めた結果、本発
明に到達した。 The present inventors have conducted research on a synthetic resin pallet that is reinforced with a reinforcing core but does not suffer from distortion due to uneven molding shrinkage in the longitudinal direction of the reinforcing core. As a result, we have arrived at the present invention.

レツトに関するものである。 The present invention provides a synthetic resin pallet reinforced with a reinforcing core, which consists of a lower pallet and an upper pallet, and the lower pallet has a deck board and a box-shaped body erected at both left and right ends of the deck board and in the center. In addition, the reinforcing core is buried in the deck board, and the end of the buried reinforcing core is exposed in the box, and the upper part of the pallet has a deck board and a box-shaped body erected at both left and right ends of the deck board and in the center. In addition, as the reinforcing core is buried in the deck board, the end of the buried reinforcing core is exposed inside the box, and the box at the bottom of the pallet and the box at the top of the pallet are thermally welded. The present invention relates to a synthetic resin pallet characterized in that the synthetic resin pallet is integrally formed with a reinforcing core and the end portion of the reinforcing core is held in a space sealed by a deck board and a box-shaped body.

The synthetic resin undergoes molding shrinkage in the longitudinal direction of the reinforcing core in the same way as other parts, making the entire molding shrinkage uniform and preventing distortion at the bottom and top of the pallet. Since the ends of the reinforcing core are confined in a sealed space after the pallet is manufactured, even though the ends of the reinforcing core are exposed outside the resin, it is possible to prevent rust from forming. can.

and a pallet upper part 2 having the same structure as this,
Turn over the upper part 2 of the pallet, and attach the end of the box 4 of the lower part 1 of the pallet to the end of the box 4 of the upper part 2 of the pallet.
After heating and melting an iron plate heated to 180 to 240°C for 30 to 90 seconds, the end of the box 4 of the lower part 1 of the pallet and the end of the box 4 of the upper part 2 of the pallet are overlapped. Heat welding can be achieved by pressing at a pressure of 0.5 to 8 kg/cm 2 for 30 to 120 seconds. Note that both ends of the reinforcing core 5 are exposed inside the box 4 in the lower part 1 and upper part 2 of the pallet. However, by overlapping the pallet lower part 1 and the pallet upper part 2 and heat welding them into one piece, both ends of the reinforcing core 5 are held in a space sealed by the deck board 3 and the box-shaped body 4, Because it can prevent contact with water,
Rust can also be prevented when the reinforcing core 5 is made of metal.
