Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a high-rise concrete large-module integral prefabricated structure and a prefabrication method. Background Art

[0002] Concrete modular construction is a construction technique that involves dividing the building's horizontal structure into several large modular structures. These modular structures are installed and connected on site to form complete single-story structures. These single-story structures are then connected vertically layer by layer to form the complete building. The main characteristics of this construction include:

[0003] 1. Modularity: The structure is divided into large modules, with a high degree of overall prefabrication and less assembly work.

[0004] 2. Fast construction: Modules are prefabricated on site in a nomadic manner and then assembled at the building construction location, which can greatly shorten the construction period.

[0005] 3. Safety: Reduces high-altitude operations and improves construction safety.

[0006] Large modules are heavy and difficult to transport using cranes. Therefore, they are fabricated on a movable formwork platform, which then transports the modules along tracks to their designated locations. This production method makes it difficult to design the molds for these modules as movable mechanical equipment. Using traditional formwork would be a significant workload, and removing the molds and transporting them outside the module would also be inconvenient. Summary of the Invention

[0007] To address the aforementioned technical issues with existing large modular structures, the present invention aims to provide a prefabricated structure and prefabrication method for high-rise concrete large modular structures. This structure utilizes a large external steel mold as its foundation, employs internal, non-disassembly formwork, and employs a design for fixing and securing the formwork. This allows for rapid and precise mold fixation, while also enabling the rapid removal and reuse of the internal support system. This allows for the rapid fabrication of large concrete modular structures.

[0008] In order to achieve the above-mentioned object, the present invention provides a high-rise concrete large module structure integral prefabricated structure, which includes two outer openable and closable molds, an edge mold, an inner double-sided formwork wall, a wall panel mold, an end shaping mold, and a supporting tooling;

[0009] The two outer retractable molds are symmetrically arranged on both sides of the bottom mold. The outer retractable mold plate adopts a segmented design. Several segments can be opened by rotation along the movement direction of the mold table and can also be opened in the direction perpendicular to the movement direction of the mold table.

[0010] The edge mold, the internal double-sided formwork wall, and the wall panel mold are non-removable templates. The end shaping mold and the supporting tooling are temporary support systems. The temporary support system is removed after the concrete is poured. The interior of the edge mold is sequentially provided with a plurality of metal limit tie knots along the height direction. The outer openable and closable mold is sequentially provided with a plurality of electromagnet belts corresponding to the metal limit tie knots along the height direction. The edge mold is magnetically connected to the plurality of electromagnet belts on the outer openable and closable mold through a plurality of metal fiber tie knots.

[0011] The edge mold and the inner double-sided formwork wall are respectively connected to the supporting tooling through a plurality of detachable connectors. One end of the supporting tooling is fixed to the bottom mold through a fixed magnetic box, and the other end is used to support the wall panel mold. The end shaping mold is installed between the edge mold and the inner double-sided formwork wall and is tied and fixed to the surrounding supporting tooling.

[0012] By pouring concrete, after the concrete has initially set, the outer retractable mold is opened and the end shaping mold and supporting tooling are removed.

[0013] Furthermore, the side openable and closable mold includes an outer mold and rotatable side molds movably connected to both ends of the outer mold, and the two outer openable and closable molds are symmetrically arranged. The two outer openable and closable molds are butt-jointed to form a rectangle for enclosing the remaining molds therein;

[0014] The outer mold and the rotatable side film can be rotated relative to each other. By rotating the rotatable side molds in the two outer openable and closable molds to be in a straight line with the outer mold, the large module can be moved at this time, and the outer mold can be rotated relative to the rotatable side mold to allow the outer mold to be disengaged from the concrete, thereby completing demoulding.

[0015] Furthermore, the edge mold, the internal double-sided formwork wall, and the wall panel mold are all steel bar truss non-disassembly templates.

[0016] Furthermore, the supporting tooling is a C-shaped tooling, which is composed of a vertical section and a horizontal section vertically connected to the two ends of the vertical section. The vertical section is connected to the edge mold and the internal double-sided mold wall through a number of detachable connectors. The horizontal section at the top of the vertical section is used to support the wall panel mold, and the horizontal section at the bottom of the vertical section is pressed onto the bottom mold by the electromagnet belt.

[0017] Furthermore, the fixed magnetic box is T-shaped, which is composed of a horizontal plate and a vertical plate vertically connected to the middle of the horizontal plate. The horizontal plate and the vertical plate can form an angle groove through connection, and the angle groove is adapted to the end of the horizontal section. By putting the angle groove on the horizontal section, the fixed magnetic box is magnetically attracted to the bottom mold so that the fixed magnetic box applies vertical force to the horizontal section to limit its vertical movement.

[0018] Furthermore, the internal double-sided formwork wall includes two membrane shells, which are connected by a plurality of tension connectors, which are connected between the sides of the two membrane shells that are close to each other, and the sides of the two membrane shells that are relatively far away are connected with supporting tooling.

[0019] Furthermore, a reinforcing back rib is installed on the back of the floor slab mold, and the reinforcing back rib is connected to the remaining supporting tooling by tensioning.

[0020] Furthermore, a tool-type internal support is provided between the floor slab mold and the bottom mold.

[0021] In order to achieve the above object, the present invention provides a prefabrication method for a high-rise concrete large modular structure integral prefabricated structure, which is used for any of the above items, and the prefabrication method comprises:

[0022] S1: Set up a track for the mobile formwork platform at the construction site to ensure that the formwork platform can move smoothly to the predetermined position on the track. Install the bottom formwork on the formwork platform and clean and lubricate the surface of the bottom formwork to ensure easy demoulding after concrete pouring. Inspect the outer openable and closable mold to ensure that the opening and closing mechanism and magnetic device of the outer openable and closable mold are working properly.

[0023] S2: Install the two outer openable and closable molds on both sides of the track and fix them in the designated positions. Adjust the positions of the outer openable and closable molds so that they are aligned with the edges of the bottom mold and fix the outer openable and closable molds to the bottom mold.

[0024] S3: Place the edge mold at the designated position of the bottom mold, use metal limit tie pieces to connect and fix the edge mold to the electromagnet belt of the outer openable and closable mold, fix the support fixture to the edge mold, and fix the lower end of the support fixture to the bottom mold through a fixed magnetic box;

[0025] S4: Place the prefabricated inner double-sided formwork wall on the bottom formwork, install support fixtures on both sides of the inner double-sided formwork wall, and adjust the position to ensure the verticality and stability of the formwork wall;

[0026] S5: Install the end shaping mold between the edge mold and the inner double-sided formwork wall, and tie it to the surrounding supporting tooling. Check and adjust the position and rigidity of the end shaping mold to ensure that it can withstand the pressure during the concrete pouring process.

[0027] S6: Place the floor slab mold on top of the supporting tooling, reinforce the back ribs to connect with the edge molds and the internal double-sided formwork wall. For floor slab molds with larger spans, install tool-type internal supports in the middle for auxiliary reinforcement to ensure that the floor slab mold does not deform during the pouring process.

[0028] S7: Tie the steel bars inside the installed non-disassembly mold. The specifications and layout of the steel bars shall be carried out according to the design drawings. The steel bar skeleton shall be fixed to the non-disassembly mold to ensure that the steel bars do not shift during the concrete pouring process.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0042] See also Figure 1 , Figure 2 , which is a structural schematic diagram of the overall prefabricated structure of a high-rise concrete large module structure provided by the present invention.

[0043] As can be seen from the diagram, the overall prefabricated structure of the high-rise concrete large module structure provided by the present invention includes six components: two outer openable and closable molds 100, an edge mold 200, an internal double-sided formwork wall 300, a wall panel mold 400, an end shaping mold 500, and a supporting tooling 600.

[0044] The two outer openable and closable molds 100 are symmetrically arranged on both sides of the bottom mold 10. The outer openable and closable mold 100 adopts a segmented design. Several segments can be opened by rotation along the movement direction of the mold table and can also be opened perpendicular to the movement direction of the mold table.

[0045] The edge mold 200, the internal double-sided formwork wall 300, and the wall panel mold 400 are non-removable formwork. The end shaping mold 500 and the supporting tooling 600 are temporary support systems that will be removed after the concrete is poured.

[0046] The edge mold 200 is provided with a plurality of metal limit anchors 210 in sequence along the height direction. The outer openable and closable mold 100 is provided with a plurality of electromagnet strips 110 corresponding to the metal limit anchors 210 in sequence along the height direction. The edge mold 200 is magnetically connected to the plurality of electromagnet strips 110 on the outer openable and closable mold 100 through the plurality of metal limit anchors 210.

[0047] The edge mold 200 and the inner double-sided mold shell wall 300 are respectively connected to the support tooling 600 through a plurality of detachable connectors 20;

[0048] One end of the support tooling 600 is fixed to the bottom mold 10 via a fixing magnetic box 630, and the other end is used to support the wall panel mold 400;

[0049] The end shaping mold 500 is installed between the edge mold 200 and the internal double-sided formwork wall 300, and is tied and fixed to the surrounding supporting tooling 600. The main function of the end shaping mold 500 is to be used as a mold. It has good rigidity and can meet the needs of concrete pouring without additional measures.

[0050] By pouring concrete, after the concrete is initially set, the outer openable and closable mold 100 is opened, and the end shaping mold 500 and the supporting tooling 600 are removed.

[0051] Compared to existing technologies, the large modular structure provided by this solution utilizes an external retractable mold 100 as its foundation. Opening the external retractable mold 100 allows for rapid demolding. Internally, an edge mold 200, an internal double-sided formwork wall 300, and a wall panel mold 400 serve as a removable formwork. Designed methods for securing and securing the removable formwork ensure rapid and precise mold fixation. Furthermore, an end-forming mold 500 and support fixtures 600 form a support system that allows for rapid removal and reuse. This overall approach enables rapid fabrication of large concrete modular structures.

[0052] Specifically, the outer openable and closable mold 100 includes an outer mold 101 and rotatable side molds 102 movably connected to the two ends of the outer mold 101. The two outer openable and closable molds 100 are symmetrically arranged, and the two outer openable and closable molds 100 form a rectangle through docking to enclose the remaining molds.

[0053] The outer mold 101 and the rotatable side mold 102 can both rotate relative to each other. By rotating the rotatable side mold 102 in the two outer openable and closable molds 100 to be in a straight line with the outer mold 101, the mold can be moved at this time, and the outer mold 101 can be rotated relative to the rotatable side mold 102 to allow the outer mold 101 to be disengaged from the concrete, thereby completing demoulding.

[0054] In this solution, the edge mold 200, the internal double-sided formwork wall 300, and the wall panel mold 400 are all steel truss non-dismantling formwork, which uses high-performance concrete non-dismantling panels as templates and uses steel trusses to provide rigidity;

[0055] Since the steel truss non-disassembly formwork can be produced in large quantities in an industrialized manner, the application cost can be effectively reduced.

[0056] Several metal limit anchors 210 are pre-embedded in the edge mold 200 in sequence and have a certain rigidity. They can be connected to several electromagnet belts 110 on the outer openable and closable mold 100 by magnetic attraction, and can effectively fix the metal limit anchors 210, thereby preventing the edge mold 200 and the outer openable and closable mold 100 from being opened and closed during pouring.

[0057] Furthermore, the supporting tooling 600 is a C-shaped tooling, which is composed of a vertical section 610 and a horizontal section 620 vertically connected to both ends of the vertical section 610. The vertical section 610 is connected to the edge mold 200 and the internal double-sided mold wall 300 through a number of detachable connectors 20. The horizontal section 620 located at the top of the vertical section 610 is used to support the wall panel mold 400, and the horizontal section 620 located at the bottom of the vertical section 610 is pressed onto the bottom mold 10 by the electromagnet belt 110.

[0058] Furthermore, the fixed magnetic box 630 is T-shaped, which is composed of a horizontal plate 631 and a vertical plate 632 vertically connected to the middle of the horizontal plate 631. The horizontal plate 631 and the vertical plate 632 can form an angle groove through the connection, and the angle groove is adapted to the end of the horizontal section 620. By putting the angle groove on the horizontal section 620, the fixed magnetic box 630 is magnetically attracted to the bottom mold 10, so that the fixed magnetic box 630 applies vertical force to the horizontal section 620 to limit its vertical movement.

[0059] The internal double-sided formwork wall 300 includes two formworks 310, which are connected by a plurality of tension connectors 320. The plurality of tension connectors 320 are connected between the sides of the two formworks 310 that are close to each other, and the sides of the two formworks 310 that are relatively far away are connected with supporting tooling 600.

[0060] The end shaping mold 500 uses a lightweight aluminum alloy template with high rigidity as the mold, and is connected to the surrounding supporting tooling 600 to improve the overall stability during pouring.

[0061] The back of the wall panel mold 400 is provided with a pre-installed reinforcing back rib 410, which can improve the rigidity of the template. The reinforcing back rib 410 is tied and connected to the remaining supporting tooling 600 to improve the overall rigidity.

[0062] Furthermore, when the span of the wall panel mold 400 is large, a tool-type internal support 420 can be set between the wall panel mold 400 and the bottom mold 10 to reinforce the middle part, and the tool-type internal support 420 can be removed after pouring is completed.

[0065] S2: Install the outer openable and closable mold 100 on both sides of the track and fix it in the designated position.

[0066] S3: Place the edge mold 200 at the designated position on the bottom mold, use the metal limiter tie 210 to connect and fix the edge mold 200 to the electromagnet belt 110 of the outer openable and closable mold 100, fix the support fixture 600 to the edge mold 200, and magnetically fix the lower end of the support fixture 600 to the bottom mold 10 through the fixing magnetic box 630;

[0067] S4: Place the prefabricated inner double-sided formwork wall 300 on the bottom form 10, install support fixtures 600 on both sides of the inner double-sided formwork wall 300, and adjust the position to ensure the verticality and stability of the formwork wall.

[0068] S5: Install the end shaping mold 500 between the edge mold 200 and the inner double-sided formwork wall 300, and tie it to the surrounding supporting tooling 600, check and adjust the position and rigidity of the end shaping mold 500 to ensure that it can withstand pressure during the concrete pouring process.

[0069] S6: Place the wall panel mold 400 on top of the support tooling 600, and connect the reinforced back rib 410 to the edge mold 200 and the internal double-sided formwork wall 300. For wall panel molds 400 with larger spans, install tool-type internal supports 420 in the middle for auxiliary reinforcement to ensure that the floor slab mold does not deform during the pouring process;

[0070] S7: Tie the steel bars inside the installed non-disassembly mold. The specifications and layout of the steel bars shall be carried out according to the design drawings. The steel bar skeleton shall be fixed to the non-disassembly mold to ensure that the steel bars do not shift during the concrete pouring process.

[0073] S10: Use a mobile formwork platform to transport the completed modules to a designated storage location, awaiting module maintenance and further construction.
