Description

Technical Field

[0001] The utility model belongs to the technical field of assembled building engineering, and particularly relates to a prefabricated hollow column structure of a flat plate non-disassembly module. Background Art

[0002] Prefabricated buildings are buildings that are formed by prefabricating the basic components of a building, such as beams, slabs, columns, and walls, in factories and then assembling them on site. Frame structures are a type of building, in which the vertical structure is frame columns and the horizontal structure is frame beams and floor slabs. Traditional prefabricated columns are solid concrete structures, which are gradually replaced by prefabricated hollow columns due to their heavy weight and difficulty in connecting upper and lower steel bars.

[0003] The existing prefabricated hollow column structure and construction process include four-sided overlapping hollow column, two-sided overlapping two-sided free formwork hollow column, four-sided free formwork hollow column and other structural forms. Among them, the four-sided overlapping hollow column is a column steel cage with concrete thin plates cast around it, the middle of the column is hollowed out, and the column steel bars are located in the surrounding concrete. The four-sided overlapping hollow column adopts the centrifugal molding process, which requires large equipment investment, and it is difficult to form a rough concrete surface in the inner cavity, which affects the overlapping effect of the secondary pouring, and the weight is too large. The two-sided overlapping two-sided free formwork hollow column is a column steel cage with concrete slabs on both sides and free formwork on the other two sides. The molding process of the two-sided overlapping two-sided free formwork hollow column requires four flips, and the production efficiency is low; the material requirements of the free formwork are extremely high, the cost is high, and it cannot be made into large components. The four-sided free formwork hollow column is a free formwork wrapped on all four sides of the steel cage, and adopts a flip casting molding process, that is, the steel cage is flipped three times, and the free formwork casting material is cast three times. This structural form has the following technical problems: the prefabricated columns have low rigidity and are easily deformed during transportation and hoisting; the forming accuracy is poor; the formwork on all four sides does not need to be removed, which makes the cost extremely high; it is difficult to pre-embed wire pipes and boxes, and the production efficiency is low; and the secondary pouring is very prone to mold expansion, etc. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a flat plate non-disassembly module for prefabricated hollow column structure to solve the problems of high production cost and low production efficiency in the existing prefabricated hollow column structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The disassembly-free template assembly includes an upper cover, a left cover, a lower cover and a right cover. The upper cover and the lower cover are relatively parallel to each other, and the left cover and the right cover are relatively parallel to each other on the left and right sides. The two adjacent cover plates are fixedly connected and have a butt joint.

[0008] The upper cover plate and the lower cover plate have the same structure, both comprising a plate body I and two embedded angle steels I, and the two embedded angle steels I are mirror-imaged on both sides of the inner surface of the plate body I.

[0009] The embedded angle steel I is an L-shaped structure, wherein one right angle side is embedded in the plate body I, and the other right angle side is exposed outside the plate body I and is perpendicular to the plate body I.

[0010] The left cover plate and the right cover plate have the same structure, both comprising a plate body II and two embedded angle steels II. The two embedded angle steels II are mirror-coated on both ends of the inner surface of the plate body II. The embedded angle steel II is used for fixed connection with the embedded angle steel I.

[0011] The embedded angle steel II is an L-shaped structure, and two right-angled sides are respectively embedded at right angles at both ends of the inner side of the plate body II.

[0012] The plate body I and the plate body II are both made of high-strength materials.

[0013] The column reinforcement system is a square reinforcement cage structure.

[0014] The steel bar protective layer pad is made of plastic material.
