Abstract

In a method of laying out abnormally-shaped grid decks, the abnormally-shaped grid decks refer to grid decks having a cut-out at the corner thereof. It is usually a problem when laying out abnormally-shaped grid decks because they will be off-balance when they are laid on the columns. Support frames are used to support the abnormally-shaped grid decks and keep them balanced and stable on the columns. However, the support frames may obstruct the working route used in construction. The method adopted in the present invention adds temporary beams to maintain the abnormally-shaped grid decks by balancing them on the columns before they are fixed and secured thereon, and thereafter the temporary beams will be removed. This method can prevent using support frames which may obstruct the working route under construction.

Abstract

A waste heat recovery system is provided. The system comprises: an appliance, a tank, a pump and a pipeline switch. The appliance comprises: a housing, a refrigeration module, a heat exchanger, and a circulating water pipe. The tank is for storing heat energy generated from the refrigeration module with water therein and/or pumping water having the saved heat energy to the circulating water pipe to heat a space provided in the appliance. The pipeline switch controls water flow between the tank, the heat exchanger and the circulating water pipe. The system allows the appliance therein to refrigerate, thaw, and/or cook food, and it reduces electric energy consumption.

Abstract

The present invention provides a vibration damping construction system including a first construction body, a second construction body, and a damping unit. The first construction body includes a reaction surface. The second construction body is accommodated in the first construction body. The damping unit is disposed between the second construction body and the reaction surface of the first construction body for reducing the vibration transferred from the first construction body.
