The utility model relates to glass curtain wall technical field, especially a kind of connecting structure of steel crossbeam and stand column, including crossbeam, stand column and sleeve core subassembly;Mounting hole is opened in stand column, and stand column is connected with crossbeam by sleeve core subassembly, and crossbeam is simultaneously connected with glass slab;Sleeve core subassembly includes sleeve core body, spring pin and isolation pin, spring pin installation groove and isolation pin installation groove are arranged on sleeve core body, spring pin installation groove is used to install spring pin, and isolation pin installation groove is used to install isolation pin, spring pin is matched with mounting hole, and isolation pin protrudes from the outer surface of sleeve core body and is contacted with the inner surface of crossbeam, to isolate the outer surface of sleeve core body with the inner surface of crossbeam.The utility model avoids smearing isolation coating or sleeving isolation sleeve on the outer surface of aluminium alloy sleeve core, improves the convenience of operation, and solves the problem of electrochemical corrosion when steel and aluminium contact, and the isolation mode is more stable and reliable, and has good durability, and can be prefabricated in factory.

The utility model discloses a kind of multifunctional ecological revetment blocks for river regulation, belong to the technical field of hydraulic engineering construction, the block includes block body and wedge, block body four side surface structures are same, are equipped with tenon, mortise and half hole, when arbitrary two side surfaces are spliced, tenon is embedded mortise, vertical wedge hole is formed in its half hole alignment, when construction, first assemble block to form revetment level, then the conical frustum wedge of same material is driven into wedge hole, wedge uses its wedge effect to generate huge radial pressure, adjacent block is locked transversely, while its lower end is deeply into foundation, provide vertical anchoring force, the utility model realizes the " transverse locking, vertical anchoring " of revetment structure, integrality, stability and anti-collapse ability are very strong, and construction is convenient, ecological friendly, with very high popularization value.

This utility model discloses a connecting terminal, comprising: a rear sleeve, an inner sleeve, and a spring. The rear sleeve has a first insertion hole, and the inner sleeve is engaged at the opening of the first insertion hole. The inner sleeve has a second insertion hole communicating with the first insertion hole, and the spring is disposed within the second insertion hole. The end face of the rear sleeve has a conductive layer, and the conductive surface of the inner sleeve is in contact with the conductive layer. The inner sleeve and the conductive layer are made of the same material to ensure normal current conduction between them and to avoid electrochemical corrosion problems caused by different materials of the inner and rear sleeves. Thus, the rear sleeve can be made of a low-cost and lightweight material, such as aluminum, to reduce costs and weight.
