The prefabricated constructional column in the embodiment can be prepared by the following steps: can process 1.2mm for the thick steel sheet steel plate bender according to design dimension, process into the interior outer mould that designs, the die block adopts 2mm thick steel sheet, carries out the solder joint according to the thickness setting and arranges to guarantee clearance size, then fix the shaping with the mounting. The inner diameter of the die is 20mm, the size of the die is manufactured according to the type and the size of the constructional column, and a direct 6-degree reinforcing mesh is internally matched. The prefabricated constructional column outer cavity die is manufactured according to the area of a single body, the outer die is separated from the inner die, a layer of reinforcing mesh is fully paved on the inner die according to reinforcing bars, the outer die is closed, fine aggregate concrete with the same grade as that of the constructional column is poured, appropriate form removal time is selected for form removal according to the strength of a prefabricated block and the appearance quality guarantee, the prefabricated block is maintained in time after the form removal, and the prefabricated block can be put into use when the strength reaches 75%.

The construction quality assurance measures of the prefabricated constructional column finished product module in the embodiment can be carried out according to the following steps: manufacturing an external cavity shell mold in advance according to a drawing, wherein the thickness of the shell mold is generally 20mm, and filling a constructional column by using fine stone concrete; for a prefabricated constructional column finished product module forming machine, an inner steel mould and an outer steel mould need to be cleaned in time each time of prefabrication, and a thin-layer release agent needs to be coated uniformly; before masonry construction is carried out, the wall body is typeset, and the height of the U-shaped hollow building block of the bottom skin constructional column is adjusted, so that the height can be properly adjusted when an external mold is prefabricated, and the building block of the top external cavity shell mold is combined with an adjacent structure more tightly; building block construction of the masonry of the outer cavity shell mold at the upper part of the ring beam and construction contents of the lower part of the ring beam are removed, when the top-layer building block is constructed, a hole can be formed in the upper part of the side surface of the outer cavity shell mold of the prefabricated constructional column finished product module or the masonry construction can be carried out from inside to outside from the opening of the outer cavity shell mold, and finally, fine stone concrete is used for carrying out internal filling; the external cavity shell mold of the finished module of the constructional column finished product processed in advance can reduce the section size of the corresponding constructional column to a certain extent, so that if the dimension of the constructional column is ensured to be consistent with the design, the external cavity shell mold can be prefabricated, the dimension of the constructional column can be correspondingly lengthened in the length direction of the shell mold (namely along the wall direction), and the common lengthened dimension is 40 mm; when the prefabricated constructional column finished product module is used for on-site secondary structure construction, masonry construction and concrete pouring are strictly forbidden to be carried out simultaneously, otherwise, the prefabricated constructional column finished product module outer cavity shell mold is caused to displace to a certain degree, when the mortar joint strength reaches a certain strength in the masonry construction, the constructional column can be subjected to pouring construction, the outer cavity shell mold can be partially and slightly reinforced during pouring, and the constructional column is ensured not to deviate from a design original position after pouring forming; in common residential construction, the construction of the prefabricated constructional column finished product module is generally divided into two stages for construction, namely, the prefabricated constructional column finished product module is divided into two constructional columns of the upper part and the lower part of a ring beam; the concrete for pouring the constructional column needs to be added with certain additives, mainly 5% of micro-expanding agent, so that the constructional column is not separated from the surrounding masonry structure, and the concrete slump is ensured to be between 180mm and 200 mm. Because the wall thickness of the outer cavity shell mold is smaller, the vibrating rod is strictly prevented from being inserted into the shell to vibrate the concrete, so that the phenomena of mold explosion, cracking and the like are easily caused; the end column of the constructional column has the condition of a slight corner at the end, for example, the end column with the corner of 100mm at the end needs to increase the thickness of the steel bar protective layer in the end column to 50mm, so as to ensure that no conflict occurs between the steel bar in the end and the installation of the outer cavity shell mold of the prefabricated constructional column finished product module; the prefabricated constructional column finished product module is adopted for construction, a sample plate is used for guiding a way, the modulus of the U-shaped hollow building block and the building block is well adjusted, and large-area construction can be carried out after the sample plate is qualified.

The specific economic benefit is compared with that of the common constructional column for analysis. The cost generated by the construction of the constructional column by taking the standard layer of the second-stage engineering of the small town of beer as an example is subjected to statistical comparison analysis: the beer small town second-phase engineering accounts for 30 single buildings, and the standard floor of the building applying the technology accounts for 50 floors, and the height of the standard floor is 2.9 m. General comparison (end posts as an example): the labor cost of the vertical mold of the common constructional column is 60.2 yuan/m 2, the material cost is 10 yuan/m 2, the masonry labor cost of the prefabricated constructional column finished product module vertical mold is 59 yuan/m 2, the material cost is 7.7 yuan/m 2, 3.5 yuan/m 2 can be saved in construction, meanwhile, the construction method can save time, effectively guarantee the construction period, is reliable in construction quality, and has good economic benefit and social benefit. Taking a specific engineering application as an example, such as beer secondary engineering, the total building area is 150000 square meters. Wherein, 5 houses with 18 floors are used for building, which is 20083.7 square meters; 1 house with 16 floors, 7132.75 square meters in total, 11 floors and 1 house with 11 floors, 2781.62 square meters in total, 23 houses with 8 floors and 64328.63 square meters in total; 6 building 2 layers are matched, and 2006.74 square meters are used; 2 commercial buildings are provided with one floor, which is 428.96 square meters; distribution room 559 square meters; basement 32624.82 square meters.
