The invention discloses a cast-in-place bridge reinforcing steel bar auxiliary installation device, and relates to the technical field of reinforcing steel bar installation, the cast-in-place bridge reinforcing steel bar auxiliary installation device comprises an installation seat, a concentric-square-shaped supporting frame is fixed on the installation seat, a pair of semi-circular-ring plates is slidably installed on the concentric-square-shaped supporting frame, and a semi-circular-ring pipe is fixed on each semi-circular-ring plate; the arc-shaped rack is in transmission connection with a radial traction assembly used for driving the radial fixing plate to slide in the radial direction. The two semicircular ring pipes are driven by the opposite sliding assembly to achieve butt joint, the function of free butt joint and separation greatly facilitates installation, a reinforcement cage needing to be installed is encircled by the two semicircular ring pipes, the clamping assembly is driven by the radial traction assembly, effective butt joint of vertical steel bars of the reinforcement cage is achieved, and the installation efficiency is improved. The one-way locking assembly facilitates radial uniform traction of the reinforcement cage, stable positioning of the cast-in-place bridge reinforcement cage is guaranteed, deformation and deviation of the reinforcement cage are effectively avoided, and the mounting and positioning quality of the reinforcement cage is greatly improved.

The application discloses an air bag mattress and bed. The air bag mattress comprises a mattress body, an air pump assembly, an air bag assembly, a heating element and a control device. The mattress body is provided with a headrest area, a neck area and a body area; the air pump assembly comprises two independent air pumps; the air bag assembly comprises two air bags corresponding to the headrest area and the neck area respectively, and the air pump is connected to the corresponding air bag through a pipeline; the heating element is integrated in the neck air bag; the control device is electrically connected to the air pump assembly and the heating element, and can control the inflation of the neck air bag and the hot compress of the heating element, and automatically switches to the inflation of the headrest air bag after a preset time, so that the switching of the cervical vertebra hot compress and the sleep support is realized. The air bag mattress and bed disclosed by the application can realize the hot compress positioning of the cervical vertebra through the air bags controlled independently in different areas, and effectively improve the use experience of users.
