The cuff for a sphygmomanometer of the present invention has an air bag (150D) that expands and contracts when air flows in and out. The air bag (150D) includes: an inner wall portion (162) positioned inside when the blood pressure cuff is wound around the wrist; an outer wall portion (161) positioned outside the inner wall portion (162); The side wall portion (163), which connects the side end portion of the inner side wall portion (162) and the side end portion of the outer side wall portion (161), is folded toward the inside of the air bag (150) in a contracted state, thereby forming a The side ends of (150D) form pads. A welded portion (168) for reducing the expansion of the pad formed by the side wall portion (163) is provided in a part of the air bag (150D) in the direction of winding toward the body. With such a configuration, it is possible to prevent the occurrence of the phenomenon of lateral deviation of the cuff, and it is possible to obtain a high-performance and highly reliable blood pressure monitor.

A retaining device (1 ) comprising a retaining barrier (3), wherein the retaining barrier (3) comprises a support frame (4) including at least three arms (5, 51, 52, 53, 54). The support frame (4) is adapted to assume a non-operating closed configuration and an operating radial configuration. In operating radial configuration, each arm (5, 51, 52, 53, 54) is oriented along a respective radial direction (50a, 50b); in non- operating closed configuration, at least a first arm (5, 51, 53) is oriented along the same radial direction (50a) of the operating radial configuration and the remaining second arms (5, 52, 54) are oriented along a direction (50c) substantially parallel to said radial direction (50a) of said at least one first arm (5, 51, 53).

The invention relates to the field of urban bridges, and discloses an auxiliary device for preventing a viaduct from settling and a construction method thereof. The auxiliary device has the function of preventing the viaduct from settling, and comprises an auxiliary bearing platform and a lateral limiting supporting part, the auxiliary bearing platform is arranged on a pile foundation of the viaduct, the outer part of an original bearing platform of the viaduct is covered with the auxiliary bearing platform, and pier studs of the viaduct penetrate through the auxiliary bearing platform; the lateral limiting supporting part comprises a supporting base and a supporting frame, the supporting base is arranged on the ground and is located at the outer sides of the pier studs, a base-connecting end of the supporting frame is connected to the supporting base, and a beam-connecting end of the supporting frame is connected to the position in which a cover beam of the viaduct is connected to the pier studs. According to the auxiliary device for preventing the viaduct from settling and the construction method thereof, the outer part of the original bearing platform of the viaduct is covered with the auxiliary bearing platform, thus the lower ends of the pier studs are more stable, and the bridge can be prevented from settling; through the adoption of the lateral limiting supporting part, the bridge can be effectively prevented from laterally deviating, and thus uneven settlement of the bridge is stopped from further deteriorating.

The invention discloses a bolting device between prefabricated bridge decks of an assembled bridge, relates to the field of bridge construction, and comprises a first bridge deck, a second bridge deck and connecting members, and both ends of the first bridge deck and the second bridge deck are arranged There are steel plates, the ends of the transverse steel bars inside the first bridge deck and the second bridge deck pass through the steel plates and are bent into reserved steel bars, which are interspersed along the middle of the reserved steel bars set at the ends of the first bridge deck and the second bridge deck There are connecting components. In the present invention, the positioning column passes through the middle part of the reserved steel bar, so that the reserved steel bar is clamped in the slot opened by the positioning column, and the reserved steel bar is sandwiched by the upper splint and the lower splint to prevent the reserved steel bar from detaching, and finally The concrete filling layer is poured at the junction of the first bridge deck and the second bridge deck, and the connecting members and the reserved steel bars are connected and fixed without welding, which effectively improves the progress of the project.

The invention discloses a forward and reverse combined bending device for granary plates. The forward and reverse combined bending device comprises a rack, a downward bending mechanism, two upward bending mechanisms and pressing mechanisms. The rack is provided with a table top used for containing granary plates. The pressing mechanisms are arranged on the upper sides of the two ends of the table top correspondingly, and the ends of the granary plates are pressed through descending of the pressing mechanisms. The upward folding mechanisms are arranged on the lower sides of the two ends of the table top correspondingly, and the ends, extending out of the table top, of the granary plates are folded upwards through upward folding of the upward folding mechanisms. The downward folding mechanism is arranged on the upper side of the position, between the two upward folding mechanisms, of the table top. A cross section is arranged at the position, below the downward folding mechanism, of the table top, and the ends, extending out of the cross section, of the granary plates are downwards folded through downward folding of the downward folding mechanism. According to the device, the two ends of the granary plates can be bent forwards and reversely through the downward bending mechanism and the upward bending mechanisms correspondingly, the production efficiency is high, the forming precision is good, large-scale and batch bending can be conducted, and the actual profile production requirement is effectively met.
