The invention discloses a building engineering prestressed concrete construction device comprising a left pedestal, a left crossbeam, a table-board, pre-stress ribs, a left clamp, a concrete member, a right pedestal, a right crossbeam, a right clamp and a tension tool; the left and right pedestals are symmetrically arranged; the left crossbeam is arranged on the left pedestal; the left clamp is arranged on the left crossbeam; the right crossbeam is arranged on the right pedestal; the right clamp is arranged on the right crossbeam; the pre-stress ribs are arranged between the left and right pedestals; the left and right clamps can clamp the pre-stress ribs; the tension tool can apply pre-stress on the pre-stress ribs. The concrete member is casted on the pre-stress ribs with the applied pre-stress; the pre-stress ribs are steel wires or steel strands; the left and right pedestals are pier type pedestals or slot type pedestals; the tension tool is an electric screw tensioning machine, an electric winch tension machine or a central hole jack.
Description
technical field [0001] The invention relates to a prestressed concrete construction device for construction engineering, which belongs to the technical field of construction engineering. Background technique [0002] During the construction process of the construction project, the quality of the concrete project directly affects the bearing capacity, durability and integrity of the structure. The requirements for the quality of concrete are: it should have correct dimensions, and should obtain good strength, compactness, uniformity and integrity. Correct construction methods and reasonable measures should be taken in every link during construction to ensure the quality of concrete works. The construction process of concrete is: preparation, transportation, pouring, compacting and curing. The construction processes are closely related and affect each other. [0003] Ordinary reinforced concrete structures have some disadvantages, such as premature cracking, low stiffness, ...
