[Problem] To allow bridging to be mounted to a jack base. [Solution] A connection fitting B, as a separate member, is attached to a rotary body 30 for adjusting the height of a vertical member D in a jack base A, and bridging C is provided via the connection fitting B.
[Problem] To more reliably achieve a falling prevention function in a bracket used for fixing a self-propelled lifting-type temporary unit. [Solution] The present invention is provided at least with: an arm part 40 that is rotatably attached so as to be rotatable in the vertical direction with respect to a body part 10; an urging element 50 that urges the arm part 40 in one rotating direction; and a gate part 60 that is provided at the tip of the arm part 40 and forms an inclined surface 61 on the lower side thereof. From a closed state in which a passing space of traverse members B is closed, the gate part 60 causes the rising traverse members B to overcome the urging by the urging element 50 by coming into contact with the inclined surface 61, and rotate the arm part 40 in the other rotating direction and allow the traverse members B only to pass upward.
A system for maintaining fish and shellfish in an anesthetic state, the system includes at least: an anesthetic tank configured to allow the fish and shellfish to be so anesthetized as to be in an anesthetic state; and a maintenance tank configured to allow the fish and shellfish anesthetized in the anesthetic tank to be maintained in the anesthetic state while being transported, wherein, in the anesthesia tank, a carbon dioxide concentration is maintained higher than or equal to 65 ppm as well as lower than or equal to 85 ppm, and an oxygen concentration is maintained higher than or equal to 60%, and wherein, in the maintenance tank, a carbon dioxide concentration is maintained higher than or equal to 10 ppm as well as lower than or equal to 40 ppm, and an oxygen concentration is maintained higher than or equal to 60%.
[Problem] To achieve a more rapid anesthetic effect on fishes. [Solution] An anesthetic liquid is produced by the step of adjusting the salt concentration in water according to a subject to be anesthetized and further adjusting the concentration of carbon dioxide so as to have an anesthetic effect. One exemplary method for adjusting the salt concentration is to adjust the salt concentration closer to the osmolality of a body fluid of the subject to be anesthetized.
A connector for temporary scaffolding at an end of a lateral member, to be wedge-connected to a receiver around a strut, includes: a wedge body provided movably at the end of the lateral member upward and downward relative to the lateral member; a locking body including a claw formed such that, as a result of the wedge-body's moving downward, the claw could travel from initial to locking position with respect to the receiver; and a biasing body capable of pressing the locking body toward the wedge body, wherein the wedge body includes a shoulder protruding toward the locking body, the locking body includes an interfering portion protruding toward the wedge body, and when the claw is at the initial position, the shoulder is blocked by the interfering portion from moving upward, thereby preventing the wedge body from moving upward and the locking body from traveling toward the biasing body.
[Problem] To facilitate positioning between a stud and another constituent member when assembling a prefabricated house. [Solution] When using an engagement structure for connecting a stud 30 and an upper member 10 or a lower member 20, an engagement part 40 is provided in advance with at least one of: a beam-side inclined surface 41 for positioning a prefabricated house in the beam direction; and a gable-side inclined surface 42 for positioning the prefabricated house in the gable direction.

METHOD FOR MANAGING FISHES AND SHELLFISHES, ANESTHESIA MAINTENANCE DEVICE, ANESTHESIA MAINTENANCE SYSTEM, ANESTHESIA MAINTENANCE METHOD AND TRANSPORTATION METHOD
[Problem]To reduce the toxic components in an aquarium to prevent sudden death of fishes and shellfishes. [Solution] According to the present invention, in an aquarium in which fishes and shellfishes in an anesthesia state are accommodated, the concentration of carbon dioxide in the aquarium is adjusted so as to promote a reaction of ammonia (NH3) into ammonium ions (NH4+). An aeration means can be used to adjust the concentration of carbon dioxide.
[Problem] To achieve both the prevention of a member breaking free during disconnection and the facilitation of removing a member during disassembly. [Solution] A connector for temporary scaffolding is provided with at least a wedge body A that can freely move vertically and relatively on the end of a horizontal member Y, a locking body B in which a claw 70 moves from an initial position to a locking position with the downward movement of the wedge body A, and a biasing body C that presses the locking body B toward the wedge body A side. The wedge body A is provided with a shoulder 40 that projects toward the locking body B side, and the locking body B is provided with an interference part 80 that projects toward the wedge body A side. In a state in which the claw 70 is in the initial position, the upward movement of the wedge body A and the movement of the locking body B toward the biasing body C side are restricted by the upward movement of the shoulder 40 being blocked by the interference part 80.
[Problem] To impart an expansion function such as that of a hook or shelf to a wall surface panel. [Solution] A means for connecting wall surface panels that constitute the wall surface of a prefabricated house is provided with an expansion means to which a construction tool for expansion can be mounted. More specifically, a rail portion, in which an opening space which is open toward an indoor side and/or outdoor side is formed continuously in a vertical direction, is formed in a female-side connector that can be connected to a male-side connector of another wall surface panel, and a construction tool for expansion is configured to be mountable to said rail portion.

PREFABRICATED HOUSE AND FLOOR MATERIAL FOR PREFABRICATED HOUSE
[Problem] To provide a means with which a prefabricated house can be converted to an OA floor without using an existing OA floor material. [Solution] A prefabricated house that is characterized in that a portion or the whole of a floor material is composed of a removable floor, and said removable floor is provided with a plug socket that is provided with at least one power supply, LAN, and/or telephone connector, said plug socket being exposed on the same plane as the top surface of the removable floor.

[Problem] To provide a highly user-friendly prefabricated house with which the effect of improved workability, prevention of the dirtying of an indoor surface, and/or the interior height of a ceiling surface can be achieved. [Solution] The present invention is characterized in that a portion to be joined to a column material is made to protrude downward on the bottom surface of an upper member that constitutes a ceiling material or roof material, at least.
