Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier construction templates, in particular to a fast-assembled bridge pier construction template. Background Art

[0002] A pier is a lower load-bearing object used to support the upper structure in civil engineering. The cross-section of a pier is mostly circular, but there are also elliptical, square, curved, parabolic and other special piers. It is an important component in highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, flyovers and other projects. During the construction of bridge piers, concrete needs to be poured into the formwork, and the formwork can be removed after the concrete solidifies. However, today's formwork does not have the function of heat preservation when in use. Therefore, when the temperature drops suddenly or construction is carried out in a cold environment, the temperature for concrete curing cannot be reached, affecting construction efficiency and quality.

After the positioning rod on the first fixing frame passes through the second fixing frame, the third pier column frame and the fourth pier frame can be positioned; then the two baffles are respectively in contact with the opposite sides of the first pier column frame and the second pier column frame, and the two A cross bar passes through the two baffles, so that the first pier column frame and the second pier column frame are located between the two cross bars, and then the two baffles are supported after being threadedly connected to the cross bars with bolts to complete the fixation of the first pier column frame and the second pier column frame. At the same time, a jack is used to drive the vertical plate to move toward the first pier column frame with the top of the jack, and the two vertical plates can respectively support the two ends of the cross bar to complete the further fixation of the first pier column frame, the second pier column frame, the third pier column frame and the fourth pier column frame; then, pour into the first pier column frame and the second pier frame The concrete is filled in the space formed by the first column frame, the second column frame, the third column frame and the fourth column frame. When the concrete is poured, the heating element is used to pass through the opening on the vertical plate far away from the fixed end of the heating element to complete the wrapping of the first column frame, the second column frame, the third column frame and the fourth column frame, and then the heating element is started to insulate the concrete in the first column frame, the second column frame, the third column frame and the fourth column frame to prevent the concrete from being affected by external cold air. When the concrete is formed, the heating element can be restored, and then the two vertical plates can be reset, and then the third column frame and the fourth column frame can be removed from the first column frame and the second column frame, and then the bolts on the cross bar can be removed. After the cross bar is removed, the first column frame and the second column frame can be disassembled. The utility model is simple and fast to disassemble and assemble, and can effectively insulate the poured concrete, so as to prevent the concrete from being affected by external cold air during the curing process after pouring, thereby affecting the curing efficiency and quality of the concrete.
