Description

Technical Field

[0001] This utility model relates to a production line for precast concrete components, and more particularly to a detachable and combinable precast component production line for solid piles, beams and columns, belonging to the field of production technology for precast concrete components for buildings. Background Technology

[0002] Beams, columns, and piles are two common structural components in building construction. Their main differences are: Beams and columns are divided into beams and columns. Beams are horizontal load-bearing members, mainly bearing bending moment and shear force, and are used to transfer the load of the floor slab or roof to the columns or walls. Columns are vertical load-bearing members, mainly bearing axial compression and bending moment, and further transferring the load transferred by the beams to the foundation. The two are usually used together to form a frame structure (such as a frame-shear wall structure).

[0003] Piles are foundation components, typically precast or cast-in-place reinforced concrete piles, driven vertically into or buried in the ground. They are used to transfer the load of the superstructure to the deep foundation, increasing the bearing capacity of the foundation or reducing settlement. They are commonly found in soft soil foundations or in the foundation engineering of high-rise buildings.

[0004] In terms of shape and construction, beams are mostly rectangular in cross-section (though T-shaped and I-shaped are also possible), while columns are mostly square, circular, or rectangular in cross-section. Longitudinal reinforcement and stirrups need to be configured according to stress requirements, and joint connections are complex (e.g., beam-column joints require seismic design). Pile cross-sections are typically square (e.g., 300mm×300mm, 400mm×400mm), and their length can be prefabricated in sections according to geological conditions. Reinforcement is relatively simple; main reinforcement is arranged longitudinally along the pile shaft, and stirrups are used for shear resistance.

[0005] In terms of production methods, beams and columns are mostly made of cast-in-place concrete, requiring formwork erection, rebar tying, pouring, and curing, resulting in a relatively long construction period. Square piles are divided into precast and cast-in-place types. Precast square piles are manufactured in a factory and then transported to the site for driving through methods such as hammering and static pressure. Cast-in-place square piles are formed by drilling and pouring concrete (such as manually excavated bored piles).

[0006] Currently, the conventional production model for prestressed beams, columns, and square piles mainly relies on long-line formwork production lines (i.e., fixed ground formwork production lines). Typical technical solutions include monolithic cast-in-place concrete tensioning frames and fixed steel formwork structures. Their characteristics are as follows: Integral cast-in-place concrete tensioned frame: The reaction beam and tensioned frame are formed by integral casting of reinforced concrete. The structure has high strength but a long construction period (usually 1-2 months) and the length or height cannot be flexibly adjusted.

[0007] Fixed steel formwork table: The mold is fixedly connected to the tensioning frame and cannot be disassembled or reused, resulting in high equipment investment costs (especially for production lines with large span and large tension requirements).

[0008] Curing system: relies on steam pipelines and drainage grooves, but lacks temperature zoning control and leakage-proof design, which easily causes energy waste or safety hazards.

[0009] Chinese Patent CN116079866A discloses a long-line self-sustaining prestressed double beam slab production line, which adopts a technology of connecting molds through flanges to form a long-line mold table, and has high overall tensioning efficiency. However, its frame is a fixed structure, which cannot adapt to the production requirements of components with different cross-sectional sizes (such as solid square piles, beams and columns). In addition, the mold replacement cost accounts for more than 40% of the total equipment investment, the foundation construction period is as long as 1-2 months, and the maintenance cost is high.

[0010] National Building Design Atlas 20G361 "Precast Concrete Square Piles": clarifies the mechanical performance parameters of 600mm cross-section prestressed square piles (single ultimate bearing capacity 9533KN), which provides a standard basis for the selection of the force-bearing column of the present invention, but does not involve the design of a detachable combined frame. Contents of the Invention

[0011] Objective of the invention: The purpose of this utility model is to address the problems existing in the prior art, such as high production cost, poor product compatibility, long construction period and high foundation requirements, and to provide a detachable combined precast component production line to realize flexible production of multiple types of components.

[0012] Technical solution: A detachable combined precast component production line, comprising a base assembly and a mold assembly, wherein the mold assembly is installed on a flat ground through the base assembly. The base assembly includes longitudinal border assemblies, tensioning beams and ground beams. Two tensioning beams are respectively arranged at both ends of two parallel longitudinal border assemblies to form a frame structure with a rectangular projection; the ground beams are arranged on the flat ground perpendicular to the longitudinal border assemblies, and the longitudinal border assemblies are installed on the ground beams; The mold assembly is formed by arranging individual mold units with an upward opening and a "U"-shaped cross section in the transverse direction inside the rectangular frame structure formed by the longitudinal border assemblies and the tensioning beams; A reinforcement cage of the component is arranged inside the individual mold unit, and both ends of the reinforcement cage are respectively connected to the tensioning beams at the two ends.

[0013] The tensioning of the steel bars of the prestressed component can be realized by connecting the two ends of the reinforcement cage to the tensioning beams at the two ends respectively.

[0014] This utility model realizes "one production line for multiple uses" through modular design, solves the pain point of "one machine for one specific use" of traditional production lines, and is especially suitable for the multi-variety and small-batch production demands of small and medium-sized precast component factories.

[0015] In a preferred embodiment, to accommodate the production needs of beams, columns, or piles of varying lengths, the longitudinal frame assembly includes individual column-shaped frame units and piers. The individual column-shaped frame units are connected along their length by piers; the bottom of each pier is connected to the ground beam. The individual column-shaped frame units are uniformly sized columnar structures made of precast concrete or steel, while the piers are steel structures. Both the individual column-shaped frame units and the piers are prefabricated in the factory, and the longitudinal frame assembly is quickly assembled on-site using bolts or welding to achieve the required length. This assembly structure reduces transportation difficulty and costs, and also lowers the requirements for on-site storage. The individual column-shaped frame units can utilize existing products such as solid square piles, eliminating the need for additional investment and reducing production costs.

[0016] In a preferred embodiment, to facilitate leveling and pipe layout, a pad is provided at the bottom of the columnar frame unit, with the upper and lower surfaces of the pad contacting the bottom surface of the columnar frame unit and the ground, respectively. By providing a pad at the bottom of the columnar frame unit, the entire base assembly can be leveled, ensuring that the centerline of tensioning and the centerline of the product are on the same straight line during tensioning. Furthermore, leaving space at the bottom facilitates pipe laying and wastewater and waste residue discharge.

[0017] In a preferred embodiment, to meet the needs of the precast component manufacturing process, a steam pipe is provided on one side of the base assembly. The steam pipe passes through the base assembly and extends to the bottom of the mold assembly, with a steam outlet at the bottom of each mold unit. In this invention, the mold assembly is assembled on-site via the base assembly, and is suspended off the ground. The steam pipe directly delivers the necessary curing steam to the bottom of each mold unit, enabling on-site curing of the precast components. This improves production efficiency while avoiding the risks of increased costs and reduced quality due to handling and maintenance.

[0018] In a preferred embodiment, to further enhance the adaptability of this production line, the longitudinal frame assembly is stacked with at least two columnar frame units along the height direction to form a multi-layer frame structure. The height of the mold assembly located inside the multi-layer frame structure matches the frame height. The piers between adjacent columnar frame units in the longitudinal direction overlap vertically. By stacking and assembling existing columnar frame units, the production needs of beams, columns, and solid piles of different heights can be met. After stacking, a multi-layer frame structure is formed, which also requires the use of mold assemblies of corresponding heights, thereby realizing flexible production of various types of components.

[0019] In a preferred embodiment, to ensure a stable and reliable connection between the individual columnar frame units, steel hoops are provided along the longitudinal direction of the stacked columnar frame units along the height direction. Each steel hoop consists of two L-shaped steel plates, which are diagonally joined to form a rectangle and secured with bolts. The lengths of the two L-shaped steel plates match the height and width of the stacked columnar frame units along the height direction. By setting multiple sets of steel hoops along the length of the stacked columnar frame units, the stability and reliability of the connection between the individual unit types can be improved. The L-shaped structure facilitates installation and is simple to manufacture.

[0020] In a preferred embodiment, to meet the production needs of solid piles, the tensioning beam includes a solid pile tensioning beam, a tensioning screw, and a transition connecting seat. The solid pile tensioning beam is fixedly installed at both ends of the longitudinal frame assembly. A tail plate is provided at the end of the reinforcing cage, and the tail plate is fixedly connected to the reinforcing cage. One end of the tensioning screw passes through the solid pile tensioning beam, and the other end is connected to the transition connecting seat. The transition connecting seat is detachably connected to the tail plate and moves longitudinally within the mold unit. To adapt to the production needs of solid piles, the transition connecting seat connects to the tail plate at the end of the solid pile. By adjusting the tensioning screw, the tension is transmitted to the solid pile tensioning beam, thereby achieving the tensioning effect on the reinforcing cage.

[0021] In a preferred embodiment, to facilitate connection and improve assembly efficiency, the transition connector is a central shell structure with a width matching the mold unit, and both ends have connecting grooves along the same longitudinal direction. The tensioning screw is located within the connecting groove, and the screw head is engaged within the shell of the transition connector. The transition connector moves longitudinally within the mold unit, and the mold unit acts as a guide, improving the stability of tensioning.

[0022] In a preferred embodiment, to meet the production needs of beams and columns, the tensioning beam includes a beam-column tensioning beam and a through-beam plate. The beam-column tensioning beam is located at both ends of the longitudinal frame assembly, and the reinforcing cage of the beam-column passes through the beam-column tensioning beam and connects to the through-beam plate. By replacing the through-beam plate, the production needs of beams and columns with different structures can be adapted, improving the adaptability of the production line.

[0023] A method for producing detachable and modular prefabricated components includes the following steps: Step 1: Plan the production line. Based on the size of the target product and the size of the site, determine the external dimensions of the production line, including the dimensions of the longitudinal frame components and the dimensions of the tensioning beams. Step 2: Design the production line. Based on the dimensions of the longitudinal frame components, the column frame units, and the piers, determine the quantity of column frame units and piers. Based on the width of the tension beam and the width of the target product, determine the width and quantity of the mold units. Step 3: Level the site. Mark the lines on site according to the production line dimensions determined in Step 1, and compact and level the site within the marked area; place pads to level the base components and lay pipelines.

[0024] Step 4: Assemble the production line, determine the position of the pier, and lay column-shaped frame units on both sides according to the size of the pier to form a longitudinal frame assembly. The two opposite piers on the longitudinal frame assembly are fixedly installed at both ends of the ground beam to form an overall frame structure. Step 5: Install the tensioning beam. Select the tensioning beam according to the product type. Use a solid pile tensioning beam for producing solid piles and a beam-column tensioning beam for producing beams and columns. The tensioning beam is installed vertically at the end of the longitudinal frame component. Step 6: Install the mold assembly. Install the mold unit of the product to be produced in the space between the two longitudinal frame assemblies. The center of symmetry of the cross section of the mold unit is at the same level as the center point of the tension beam and is symmetrically distributed on both sides of the center point of the tension beam. Step 7: Pour concrete. Place and position the steel cage in each mold unit. After the prestressed steel bars are tensioned in place, pour and vibrate the concrete in the mold unit cavity to the required height and smooth the surface. Step 8: Curing the components. After the concrete is poured, choose natural curing or steam curing for the components. Step 9: Demolding. After the concrete reaches its strength, first loosen the tension nuts to release the tension of the component, then disassemble and remove the mold assembly, and finally lift out the formed component. Step 10: Continue cleaning the mold, and repeat steps 6 to 9 until all similar products have been produced.

[0025] This invention, through its modular layout, enables the construction of small, convenient, and low-cost production lines that can be adapted to local conditions, thus meeting the needs of personalized product production.

[0026] Beneficial Effects: This utility model achieves "multi-purpose use of a single line" through modular design, solving the pain point of traditional production lines that rely on "dedicated machines for specific purposes." It is particularly suitable for the multi-variety, small-batch production needs of small and medium-sized precast component factories. The longitudinal frame components adopt an assembly structure, which reduces transportation difficulty and costs, and also reduces the requirements for on-site storage conditions. The columnar frame units can use existing products such as solid square piles, requiring no additional investment and reducing production costs. The mold components are assembled on-site through the base components. Simultaneously, the mold components are suspended off the ground, and steam pipelines directly deliver the necessary curing steam to the bottom of each mold unit, enabling on-site curing of the precast components. This improves production efficiency while avoiding the risks of increased costs and quality degradation caused by handling and maintenance. Attached Figure Description

Furthermore, leaving space at the bottom facilitates pipe laying and wastewater and waste residue discharge.

[0036] In order to meet the needs of the prefabrication process, a steam pipe 3 is provided on one side of the base assembly 1. The steam pipe 3 extends from one side through the base assembly 1 to the bottom of the mold assembly 2. Each mold unit 21 has a steam outlet at the bottom of the steam pipe 3.

[0037] In this invention, the mold assembly 2 is assembled on-site through the base assembly 1. At the same time, the mold assembly 2 is suspended off the ground. The steam required for curing the precast parts is directly delivered to the bottom of each mold unit 21 through the steam pipeline 3.

[0038] To meet the production needs of solid piles, the tensioning beam 12 includes a solid pile tensioning beam 121, a tensioning screw 122, and a transition connecting seat 123. The solid pile tensioning beam 121 is fixedly installed at both ends of the longitudinal frame assembly 11.

[0041] The present utility model realizes "multi-purpose for one line" through modular design, solves the pain point of "special machine for special use" of traditional production lines, and is especially suitable for the multi-variety and small-batch production demands of small and medium-sized prefabricated component factories.

[0042] In order to individually adapt to the production requirements of beams and columns of different lengths, the longitudinal frame assembly 11 includes columnar frame units 111 and piers 112. The columnar frame units 111 are connected in the length direction through the piers 112; the bottom of the pier 112 is connected to the ground beam 13.

The piers 112 between adjacent columnar frame units 111 in the longitudinal direction overlap vertically. By stacking and assembling the existing columnar frame units 111, the production needs of beams and columns of different heights can be met. After stacking, a multi-layer frame structure is formed, and mold assemblies 2 of corresponding heights are also required, thereby realizing flexible production of various types of components.
