Connection construction for wooden swimming pool, has angles bent corresponding to angle of side walls and broader than groove and spring, where angles are as thick as spring and two laterally abutting planks are connected with each angle

摘要

The construction has four to ten-angular profiles whose side walls (1) are arranged on a base plate (3) by horizontal planks. The planks are connected with each other by groove-spring connections, where the two laterally abutting planks are connected with each angle. The angles are bent corresponding to an angle of the side walls and are broader than a groove and spring, where the angles are as thick as the spring.
