A device for connecting a kickstand to a bicycle includes a first connective member, a second connective member and a fastener. The first connective member is connected to a chain stay and a seat stay. The first connective member includes a claw formed thereon for holding a shaft of a rear wheel and a cavity defined therein. The kickstand is pivotally connected to the second connective member. The second connective member includes a block fit in the cavity so that the first and second connective members cannot be rotated with respect to each other. The fastener is used for fastening the first and second connective members to each other.

Stay in place molds for the construction of concrete structures having fiber cement panels held together by multiple holding units is described. The holding units requires a flat rectangular main body; an indentation substantially located at the center of the upper side of the flat rectangular main body; left and right lateral edges perpendicularly located at the lateral sides of the rectangular body and a lower edge perpendicularly positioned at the lower side of the bottom side of the flat rectangular main body. They are selectively distributed at the internal cavity of the molds as a series of columns and rows separated from each other at predetermined distance. The particular structure and its distribution pattern facilitate the uniform contact of the liquid cement mixture and increase the strength and resistance of the structure prepared using the molds.

The invention provides a construction method for a building sandwich composite wall. The construction method for the building sandwich composite wall comprises the following steps: (1) manufacturing a concrete external wall on an industrialized production line; compounding an insulating layer on the external wall; enabling a non-metallic connecting rod to penetrate the insulating layer, enabling a first anchoring body on the connecting rod to be placed in the external wall, and enabling a second anchoring body on the connecting rod to be located at the outer side of the right end of the insulating layer to form a two-layer composite wall after external wall maintenance; (2) transporting the two-layer composite wall to a construction site, and then, arranging a template at the right side of the insulating layer; connecting the second anchoring body on the connecting rod and a wire cable, and enabling the other end of the wire cable to pass through the template to be connected with a permanent seat to form a cavity between the template and the insulating layer; (3) pouring concrete in the cavity to form an internal wall after maintenance; (4) removing the permanent seat and the template in sequence to form the building sandwich composite wall. According to the construction method provided by the invention, compounding of the external wall and the insulating layer is finished during industrialized production, and pouring of the internal wall is finished at the construction site, so that the defects of the prior art are solved.
