Abstract: The present disclosure relates to a field of construction engineering, and in particular to a reinforcing structure of a concrete overhead layer before a building expires. The reinforcing structure of the concrete overhead layer includes supporting structures, connecting structures, and metal members; wherein the reinforcing structure is configured to reinforce a concrete floor slab and/or a concrete beam; through holes are disposed on the concrete floor slab; each of the supporting structures passes through each of the through holes and the supporting structures are configured to support the concrete floor slab and/or the concrete beam; and each of the connecting structures is configured to fix each of the supporting structures on each of the metal members; each of the metal members is disposed on each of the through holes.

Abstract: The present invention relates to a reinforcing structure of unexpired concrete building floors used for reinforcing a concrete column, a concrete beam and a concrete floor slab. The structure has: at least one external column each of the at least one external column wrapping around the concrete column; at least one framework each wrapping around the concrete beam; a plurality of brackets fixedly mounted to the lower surface of the concrete floor slab, and a base plate disposed at the bottom of the concrete column, wherein the bottom of each of the at least one external column is fixed to the base plate, the top of each of the at least one external column is fixed to a corresponding one of the at least one framework, and the corresponding framework is fixed to the plurality of brackets along a length direction of the concrete beam.

Abstract: A refrigeration system and a heat exchanger are provided. The refrigeration system includes a compressor, a micro-channel condenser, a micro-channel evaporator and at least one throttling device which are connected by pipelines. Each of the micro-channel condenser and the micro-channel evaporator includes an inlet manifold and an outlet manifold, and a plurality of flat tubes being connected between the inlet manifold and the outlet manifold. The inlet manifold of the micro-channel evaporator is provided with a baffle, and the inlet manifold of the micro-channel evaporator is divided by the baffle into multiple manifold sections, and the manifold sections of the inlet manifold are isolated from each other by the baffle, and are each in communication with a certain number of the flat tubes, and are each not provided with a distribution pipe configured to distribute flow rate into the flat tubes in communication with the manifold sections.

Abstract: Disclosed a load measurement system (100) includes a compartment (110), a damper (112) and a weight calculation unit (131). The damper (112) is configured to be positioned between the compartment (110) and a platform (121) and to compress at a predetermined rate based on a load of the compartment (110). The weight calculation unit (131) is configured to calculate a weight of the compartment (110) based on the compression of the damper (112).
