Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a precast column mold that facilitates the adjustment of the spacing of pre-embedded steel bars. Background Technology

[0002] Currently, in prefabricated column components, secondary structural reinforcing bars are symmetrically reserved. During component production, openings are usually made in the side molds. When the spacing of the reserved reinforcing bars is adjusted, the openings need to be remade in the side molds, which increases the types of molds and requires repeated mold adjustments. This results in problems such as low production efficiency, high production costs, and long construction periods for prefabricated columns, failing to demonstrate the advantages of prefabricated buildings. Utility Model Content

[0025] In one scenario, when the secondary structural reinforcement is located in the middle of the precast column, three assembled steel molds (upper assembled steel mold 401, variable assembled steel mold 403, and structural assembled steel mold 402) are used along the height of the precast column. The upper assembled steel mold 401 has a pre-reserved tie rod 8 at the top for positioning and tensioning of the upper part of the mold. The lower part has a 20mm inward measurement from the edge, followed by protruding steel bars (threaded) every 500mm. The structural assembled steel mold 402 has protruding steel bars (threaded) at both the upper and lower parts, measured 20mm inward from the edge, followed by protruding steel bars (threaded) every 500mm. It also has through holes with a diameter of 14mm, measured 150mm inward from the edge, followed by through holes every 200mm, for the extension of the structural reinforcement. The variable assembly steel mold spacing 403 is measured 20mm inward from the edge at both the top and bottom, and then a protruding steel rod (threaded) is reserved every 500mm. The distance from the steel rods on both sides to the two ends of the assembly mold 4 is 50mm.

[0026] During the assembly process, the variable assembly steel mold 403 is placed first, followed by the structural assembly steel mold 402. The steel plate 5 and the steel pad 6 have two rows of holes pre-cut. The steel pad 6 is used to connect the variable assembly steel mold 403 and the structural assembly steel mold 402. Then, the nuts are tightened to complete the connection. Next, the assembly steel mold 401 is placed on the structural assembly steel mold 402. The steel pad 6 is used to connect the upper assembly steel mold 401 and the structural assembly steel mold 402. Then, the nuts are tightened to complete the connection. The long steel plate 5 is bolted to the lower 2 of the side steel mold at its end, and then assembled with the upper 3 of the side steel mold to complete the mold assembly.

[0027] Example 2

[0028] When the secondary structural reinforcement is located at the edge of the precast column, three assembled steel molds (upper assembled steel mold 401, variable assembled steel mold 403, and structural assembled steel mold 402) are used in the height direction of the precast column. The upper assembled steel mold 401 has a pre-reserved tie rod 8 tie rod 7 at the top for positioning and tie action at the top of the mold. The lower part is pre-reserved with protruding steel bars (threaded) measured 20mm inward from the edge. The structural assembled steel mold 402 has protruding steel bars (threaded) measured 20mm inward from the edge at both the top and bottom, and then pre-reserved every 500mm. At the same time, it has a 14mm diameter through hole measured 150mm inward from the edge, and then pre-reserved every 200mm for the extension of the structural reinforcement. The variable assembly steel mold 403 has a 20mm inward measurement at both the top and bottom, and then a protruding steel rod (threading) is reserved every 500mm. The distance from the steel rods on both sides to the two ends of the assembly mold 4 is 50mm.

[0029] During the assembly process, the structural assembly steel mold 402 is placed first, followed by the variable assembly steel mold 403. The steel plate 5 and steel pad 6 have two rows of holes pre-cut. The variable assembly steel mold 403 and the structural assembly steel mold 402 are connected by the steel pad 6, and then the nuts are tightened to complete the connection. Then, the assembly steel mold 401 is placed on the structural assembly steel mold 402, and the assembly steel mold 401 and the structural assembly steel mold 402 are connected by the steel pad 6, and then the nuts are tightened to complete the connection. The long steel plate 5 is bolted to the lower 2 of the side steel mold at the end, and then assembled with the upper 3 of the side steel mold to complete the mold assembly.

[0030] According to the actual needs of the project, only the position and spacing of the openings of the structural assembly steel mold 402 need to be adjusted to complete the adjustable reserved steel bars, which saves molds and achieves high efficiency. Only the structural assembly steel mold 402 needs to be changed to achieve the variable effect, saving the construction period.
