The present application relates to the technical field of house building, and especially to a new secondary structure corner horn, which comprises a wall, a main and secondary beam, a construction column template, a funnel pouring opening, a receiving box and a plurality of opposite pull bolts, the construction column template is connected with the wall through the opposite pull bolts, the top of the funnel pouring opening is overlapped on the bottom of the main and secondary beam, a through slot is formed in one side of the construction column template, and a closable opening is formed in one side and the bottom of the funnel pouring opening. The pouring concrete enters the inside of the construction column template through the closable opening in one side of the funnel pouring opening, and the construction column is built. When the position of the construction column is located at the joint position of the main and secondary beam, the funnel pouring opening does not need to be lowered, which is beneficial to avoid the exposure of the construction column reinforcement, and the concrete excess material is discharged from the closable opening in the bottom template, so that the effect of recycling the concrete excess material in the horn is achieved.

The utility model discloses a foundation pit supporting device which comprises a hydraulic cylinder and an installation support, and the installation support is located between an enclosing purlin base portion and a continuous wall enclosing purlin and located between two adjacent enclosing purlin protruding portions. The mounting bracket comprises a fixed frame and a movable frame, one end of the fixed frame is lapped on the top surface of the enclosing purlin base part and is fixedly connected with the enclosing purlin base part, a slot is formed in the side surface of the other end of the fixed frame, one end of the movable frame is inserted into the slot and is in sliding connection with the slot, and the other end of the movable frame is lapped on the top surface of the continuous wall enclosing purlin; the movable end of the hydraulic cylinder abuts against the inner side face of the movable frame. The device has the advantages that the device is simple in structure and firm in installation, the movable frame can move along with deformation of the continuous wall enclosing purlin and can also move along with pushing of the hydraulic cylinder, the movable frame provides part of supporting force for the hydraulic cylinder, meanwhile, the force application area of the hydraulic cylinder on the continuous wall enclosing purlin is increased, and the service life of the continuous wall enclosing purlin is prolonged. And the continuous wall enclosing purlin is prevented from being damaged due to too small stress area.

This utility model relates to the field of aquaculture equipment technology and discloses a marine aquaculture net fixing device, comprising a first mounting plate, a second mounting plate, a connecting block, an arc-shaped spring plate, a locking device, a connecting post, and a limiting hole. The arc-shaped spring plate is an open ring shape, connecting the two mounting plates through the connecting block. The elasticity allows the mounting plates to close and clamp the net, and facilitates the threading of ropes to connect other facilities. The two mounting plates are respectively provided with connecting posts and limiting holes on corresponding sides for accurate alignment, ensuring even force on the net and preventing displacement and damage. The locking device includes a base, a first connecting rod, a second connecting rod, a locking rod, and other components. These components work together to achieve quick locking and unlocking of the mounting plates. The collar guides and limits the locking rod, improving locking reliability. The handle at the hinge is easy to operate, reducing labor intensity. The bent rod on the locking rod engages with the connecting post insertion hole to form a stable connection, resisting seawater impact, ensuring the mounting plates are tightly fixed, and preventing the net from loosening and slipping. It is suitable for complex aquaculture environments.

The application relates to a prestress tension system and a construction method thereof, and relates to the technical field of a prefabricated beam tension pedestal. The system comprises a base and end crossbeams. Two end crossbeams are symmetrically and fixedly installed on the base. A plurality of steel strands are arranged. The two ends of the steel strands are respectively arranged on the two end crossbeams. A plurality of groups of embedded parts are symmetrically embedded on the two end crossbeams. The steel strands are arranged in the embedded parts. A stress diffusion part comprises a stress plate. A plurality of stress holes are arranged on the stress plate. The steel strands are correspondingly arranged in the stress holes. A plurality of reinforcing plates are arranged. The reinforcing plates are fixedly installed on the stress plate. The reinforcing plates are connected with the embedded parts. A bottom plate is fixedly installed at the bottom of the stress plate. The bottom plate is fixedly connected with the reinforcing plates. The prestress steel strands can reduce the local stress generated on the end crossbeams, and the prestress steel strands can avoid damaging the end crossbeams.

The support module comprises a supporting assembly and a connecting frame, the first end of the supporting assembly is rotationally connected to the connecting frame, the second end of the supporting assembly is rotationally connected to a fixed base, the fixed base is fixedly connected with a vehicle body, and the connecting frame comprises a closed outer frame body structure; the rotating process of the connecting frame with the fixed base as the rotating center at least comprises a first position, and the connecting frame is completely embedded into the vehicle body when located at the first position. The rotating process of the connecting frame with the first end of the supporting assembly as the rotating center at least comprises a second position, and when the connecting frame is located at the second position, the connecting frame is higher than the supporting assembly in horizontal height and supported by the supporting assembly. The connecting frame has a two-stage rotating function through the supporting assemblies hinged to the two ends, the connecting frame can be switched from the containing position to the using position, and meanwhile the connecting frame is provided with the closed outer frame body to be stably supported by the supporting assemblies.
