Description

Technical Field

[0001] This invention relates to the technical field of prefabricated building assembly molds, specifically to a composite assembly mold for a modular frame structure and its production method. Background Technology

[0002] Currently, the construction industry generally relies on on-site pouring, which is labor-intensive and has relatively extensive operating methods. It still has obvious shortcomings in terms of industrialization, greening, and intelligentization, which has become the main bottleneck for the sustainable development of the industry.

[0003] The industrialized production and prefabricated construction in the building industry mainly rely on "prefabricated floor slabs, wall panels, and stair slabs." This construction mode, characterized by "a small number of prefabricated components, with frequent alternation between on-site assembly and cast-in-place work," makes it difficult to fully leverage the advantages of industrialization and green construction in prefabricated construction. Modular integrated building is an alternative solution. By breaking down buildings into standardized modular units and adopting a "five-in-one" model of standardized design, factory production, prefabricated construction, integrated decoration, and digital management, it significantly shortens the construction period and reduces construction waste, achieving the goals of industrialized, green, and low-carbon construction.

[0004] While modular structures with shear walls can improve seismic performance, the shear walls in such structures consist of two modular structural units and a cast-in-place composite layer. The relatively thin shear walls in these modular units make it difficult to achieve dense concrete compaction during pouring. Furthermore, low-rise or multi-story structures do not require additional shear walls to provide lateral stiffness. Therefore, modular frame structures are a viable option for low-rise or multi-story buildings with large spans, offering advantages such as flexible structural layout and clear force transmission. However, the current production of modular frame structural units largely relies on manual labor, resulting in low production efficiency and product quality. Summary of the Invention

[0005] To address at least one of the problems existing in the prior art, this invention provides a composite assembly mold and production method for a modular frame structure. By reducing the complexity of the assembly mold, the production efficiency of the modular frame structure unit is further improved. The top composite mold significantly reduces the self-weight and cost of the top mold, improving safety and economy. By eliminating the concrete shear wall of the modular structure, the product quality of the modular frame structure unit is further improved.

[0006] To achieve the objective of this invention, the present invention provides a modular frame structure composite assembly mold, comprising: Bottom steel formwork system; The fixed short-side steel mold system and the fixed long-side steel mold system each include a fixed short-side steel mold and a fixed long-side steel mold installed on adjacent sides of the bottom steel mold system; The sliding short-side steel mold system and the sliding long-side steel mold system each include a sliding short-side steel mold and a sliding long-side steel mold that can be movably installed on the other two sides of the bottom steel mold system. A top composite mold system is detachably mounted on top of each side steel mold system to enclose the top space of the mold. Among them, the two ends of the fixed long side steel formwork system and the two ends of the sliding long side steel formwork system are respectively hinged to the first side steel formwork and the second side steel formwork of the column. The first side steel formwork and the second side steel formwork of the column can be unfolded or closed. The top of the first side steel formwork and the second side steel formwork of the column can be detachably set with the third side steel formwork of the column. After the first side steel formwork and the second side steel formwork of the column are closed, they together with the third side steel formwork of the column to form the column casting space. Hydraulic jacks for hydraulic demolding of the first column side steel mold are installed on the fixed short side steel mold, the sliding short side steel mold, and the first column side steel mold. Hydraulic jacks for hydraulic demolding of the second column side steel mold are installed on the fixed short side steel mold, the sliding short side steel mold, and the second column side steel mold. Hydraulic jacks for hydraulic demolding of the sliding long side steel mold are installed on the fixed short side steel mold and the sliding long side steel mold. Hydraulic jacks for hydraulic demolding of the sliding short side steel mold are installed on the fixed long side steel mold, the sliding long side steel mold, and the top composite mold. During demolding, hydraulic jacks for hydraulic demolding of the top composite mold system are installed between the fixed long side steel mold, the sliding long side steel mold, and the top composite mold.

[0007] Furthermore, the steel mold is provided with multiple transverse threaded holes for installing jack ear plates; one end of the hydraulic jack used for hydraulic demolding of the top composite mold system is connected to the fixed long side ear plate provided on the fixed long side steel mold or the sliding long side ear plate provided on the sliding long side steel mold, and the other end is connected to the corresponding jack ear plate.

[0008] The present invention provides a method for producing a composite assembly mold with a modular frame structure, comprising the following steps: Formwork assembly steps: Connect and fix the fixed short-side steel formwork system to the fixed long-side steel formwork system; move and fix the sliding short-side steel formwork system and the sliding long-side steel formwork system into position; after installing the base plate and column reinforcement mesh inside the formwork, rotate and fix the first and second side steel formwork of the column, and install the third side steel formwork on top of both the first and second side steel formwork of the column; hoist the top composite formwork system into position and fix it; install the top plate and beam reinforcement mesh, connect and fix the fixed long-side steel formwork and the sliding long-side steel formwork, and pour concrete; Demolding steps: After the concrete has cured, remove the connecting parts in sequence and manually demold the steel formwork on the third side of the column; start the corresponding hydraulic jacks to hydraulically demold the steel formwork on the first side of the column, the steel formwork on the second side of the column, and the top composite mold system; start the corresponding hydraulic jacks to hydraulically demold the sliding long side steel formwork and the sliding short side steel formwork; finally, hoist the completed modular frame structure unit as a whole to complete the mechanical demolding of the fixed long side steel formwork and the fixed short side steel formwork.

[0009] Compared with the prior art, the present invention has the following significant features: 1. By reducing the complexity of assembly molds, the production efficiency of modular frame structure units is further improved: The shear wall side steel mold system of the modular frame structure unit with shear wall is eliminated. The first and second side steel molds of the columns of the modular frame structure unit can be quickly assembled using industrial hinges and quickly demolded using hydraulic jacks installed on the fixed short side steel mold, sliding short side steel mold, first side steel mold, and second side steel mold, without damaging themselves or the concrete columns. This invention, based on the first and second side steel molds of the columns of the modular frame structure unit, improves the assembly and demolding speed of the assembly molds, further enhancing the production efficiency of the modular frame structure unit.

[0010] 2. The use of a top composite mold significantly reduces the weight and cost of the top mold, improving safety and economy: The top composite mold includes a polypropylene plastic mold and a steel mold. The polypropylene plastic mold can significantly reduce the weight of the top mold, ensuring the safety of mold assembly and demolding, while also significantly reducing the cost of the top mold. This invention, based on a top composite mold system, can significantly reduce the weight and cost of the top mold, improving safety and economy.

[0011] 3. By eliminating the concrete shear walls in the modular structure, the product quality of the modular frame structure unit is further improved: The shear wall in the modular structure consists of two modular structural units and a cast-in-place post-cast composite layer. The shear wall thickness of the modular structural units is relatively small, making it difficult to achieve dense concrete pouring. Eliminating the concrete shear walls in the modular structure can further improve the product quality of the modular structure. This invention further improves the product quality of the modular frame structure unit by eliminating the concrete shear walls in the modular structure. Attached Figure Description

[0063] Example 3 like Figure 20 , Figure 21 As shown, a composite assembly mold based on modular frame structural units was used to produce modular frame structural units. During the assembly and demolding process, only some areas were assembled and demolded manually, while most areas were assembled and demolded mechanically. Due to the adsorption force between the modular frame structural units and the assembly mold, the external load required for demolding in some areas was relatively large. To verify the feasibility of this assembly mold, the feasibility and efficiency of the demolding process were verified using commonly used dimensions of modular frame structural units. For example, the modular frame structural unit has dimensions of 6m × 3m × 2.88m, column and beam cross-sections of 400mm × 400mm and 400mm × 400mm respectively, and top and bottom plate thicknesses of 100mm each.

[0064] Table 1 Demolding Adhesion Force of Modular Frame Structure Units

[0065] Among them, the values ​​in brackets of mold length one and mold length two of sliding long side steel mold 51, sliding short side steel mold 41, fixed long side steel mold 31 and fixed short side steel mold 21 are the lengths of the areas where no concrete has been poured.

[0066] Table 1 shows the demolding adhesion force of the modular frame structure unit. According to the "Technical Specification for Prefabricated Concrete Structures", the average adhesion force during the concrete demolding stage is 1.5 kN / m. 2 The adsorption force of the third-side steel mold 6 of the column is 0.27kN, making it relatively easy to demold manually. The adsorption forces of the first-side steel mold 38, the second-side steel mold 58, the top composite mold 71, the sliding long-side steel mold 51, and the sliding short-side steel mold 41 range from 1.06kN to 27kN, making them more difficult to demold manually. Therefore, a hydraulic demolding method is used. The adsorption forces of the fixed long-side steel mold 31 and the fixed short-side steel mold 21 are 7.36kN and 5.11kN, respectively. However, since these two side steel molds are fixed to steel supports, a mechanical demolding method using the hoisting of modular frame structure units is adopted for demolding.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined in this invention may be implemented in other embodiments without departing from the spirit or scope of the invention.
