[0002] Under the national policy of promoting new building industrialization, prefabricated building structure technology has increasingly higher requirements for industrialization and assembly.

[0003] Existing technologies typically employ prefabricated concrete frame structures or steel frame structures. However, prefabricated concrete frame structures suffer from issues such as exposed reinforcement in precast components and dense reinforcement in joint areas, requiring temporary supports and formwork on-site. This results in a significant amount of on-site work and a longer construction period. Steel frame structures, due to the properties of steel, require fireproofing and corrosion protection measures, leading to higher construction costs.

[0004] Therefore, a precast frame column with steel strip connectors is needed to at least solve the above problems. Utility Model Content

[0011] In some embodiments of the present application, in the state that the steel lath connector is connected to the frame column body, the support plates are located outside the frame column body; the support plates are arranged in parallel with the longitudinal reinforcement, and the second connecting part is a plate structure and is arranged perpendicularly to the support plates.

[0012] In some embodiments of the present application, the prefabricated frame column is integrally formed by pouring concrete through the frame column body and the steel lath connector; one side of the support plate facing away from the cuboid frame structure is exposed outside the concrete.

[0013] In some embodiments of the present application, the stirrup comprises a plurality of ring stirrups and a plurality of tension reinforcement, the plurality of ring stirrups are sleeved on the outer circumferences of the plurality of longitudinal reinforcements, the plurality of tension reinforcements are arranged in the plurality of longitudinal reinforcements and connected to the longitudinal reinforcements, the cross section of the frame column body is any one of a rectangle, a cross, a T shape, an L shape, and a Z shape; and at least part of the ring stirrups are arranged inside the cuboid frame structure.

[0017] Compared to existing technologies, the precast frame column with steel strip connectors provided in the first aspect of this application avoids the difficulties in rebar connection caused by exposed rebars and dense rebar in the joint area in traditional precast concrete frame structures.

DETAILED DESCRIPTION

[0035] Exemplary embodiments of the present application will be described in detail with reference to the drawings. Although exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thoroughly and completely understood, and will fully convey the scope of the application to those skilled in the art.

[0036] It should be noted that, unless otherwise specified, the technical or scientific terms used in the present application should be understood as the common meaning understood by those skilled in the art to which the present application belongs.

[0037] The assembled concrete frame structure system usually adopts the assembled monolithic frame, and the stress performance thereof is equivalent to that of the cast-in-place structure, the seismic performance thereof is good, and the overall construction cost is low. However, the system has the problems of complex out-joint of the prefabricated component, and dense steel bars in the node area, and in the construction process, temporary support and formwork need to be set on site, which increases the on-site operation amount and prolongs the construction period.

[0038] The frame column of the steel frame structure system usually adopts a rectangular steel pipe column or an H-shaped steel column, and the steel beam adopts an H-shaped section. The beam-column connection mode has the forms of short beam, flange-welded web bolting or full welding. The advantage of this system is a short construction period, but the disadvantage is that fireproofing and corrosion prevention measures need to be taken, resulting in a high construction cost.

[0039] It can be seen that the key to solving the assembled frame structure lies in solving the beam-column connection node problem. In order to solve various problems existing in the above two technical systems, the application adopts the method of pre-setting a connecting piece on the prefabricated frame beam and the prefabricated frame column to solve the problem of difficult steel bar connection.

[0040] Embodiment 1

[0041] The embodiment of the application provides a prefabricated frame column with a steel strip connecting piece, as shown in Figures 1 to 9 The prefabricated frame column with the steel strip connecting piece comprises a frame column body 101, a node domain is arranged on the frame column body 101, the frame column body 101 comprises a plurality of longitudinal reinforcement bars 1011 and a plurality of stirrups, a steel strip connecting piece 102, the steel strip connecting piece 102 has a plurality of longitudinal and transverse intersecting spaces inside, the plurality of longitudinal reinforcement bars 1011 and the plurality of stirrups respectively pass through the plurality of spaces so that the steel strip connecting piece 102 is pre-buried in the node domain, and the steel strip connecting piece 102 further comprises at least one second connecting part 1021, the second connecting part 1021 is located outside the frame column body 101, and the second connecting part 1021 is used for pre-connection with a first connecting part of a prefabricated frame beam 2.

[0042] The prefabricated frame beam 2 and the prefabricated frame column 1 play a supporting role in the field of building. The frame column body 101 can be prefabricated in a factory, and the plurality of longitudinal reinforcement bars 1011 and the plurality of stirrups are arranged according to design requirements during manufacturing. Meanwhile, the steel strip connecting piece 102 is manufactured, and a plurality of longitudinal and transverse intersecting spaces are designed inside the connecting piece. In the assembly process, the longitudinal reinforcement bars 1011 and the stirrups respectively pass through the plurality of spaces of the steel strip connecting piece 102, the assembled steel strip connecting piece 102 is pre-buried in the node domain of the frame column body 101, and the steel strip connecting piece 102 is ensured to be stably connected with the frame column body 101.

[0043] The first connecting part is arranged on the prefabricated frame beam 2, and the second connecting part 1021 outside the frame column body 101 is arranged on the steel strip connecting piece 102. In the construction site, the prefabricated frame beam 2 can be hoisted to the designed position, and the prefabricated frame beam 2 is pre-connected with the prefabricated frame column 1 through the first connecting part and the second connecting part 1021, so that the prefabricated frame column with the steel strip connecting piece is initially built.

[0044] The steel strip connecting piece 102 is embedded into the node domain after the longitudinal reinforcement 1011 and the stirrup pass through the spaces, so that the problem of difficult steel bar connection caused by the out-joint of the prefabricated component and the dense steel bars in the node area in the traditional fabricated concrete frame structure is avoided, the steel bar connection is more orderly and convenient, the prefabricated frame beam 2 and the prefabricated frame column 1 are pre-connected through the connecting parts, the amount of steel bar connection operation, the temporary support and the formwork setting in the construction site are greatly reduced, the construction difficulty is reduced, the construction period is shortened, and the construction cost is controlled.

[0045] In some embodiments, a plurality of first connecting holes are arranged on the first connecting part, a plurality of second connecting holes 1022 are arranged on the second connecting part 1021, and the first connecting part and the second connecting part 1021 can be connected by sequentially passing through the first connecting hole and the second connecting hole 1022 through the connecting piece.

[0046] During the prefabrication in the factory, a plurality of first connecting holes can be arranged on the first connecting part of the prefabricated frame beam 2 according to requirements, and a plurality of second connecting holes 1022 can be arranged on the second connecting part 1021 of the steel strip connecting piece 102 of the prefabricated frame column 1. The plurality of first connecting holes and the plurality of second connecting parts 1021 can be bolt holes, and the arrangement modes are the same. When the prefabricated frame beam 2 and the prefabricated frame column 1 are connected in the construction site, appropriate connecting pieces such as bolts can be selected. The bolt is sequentially passed through the first connecting hole of the first connecting part and the second connecting hole 1022 of the second connecting part 1021, and then the nut and other matched parts are tightened, so that the prefabricated frame beam 2 and the prefabricated frame column 1 are pre-connected. The prefabricated frame beam 2 and the prefabricated frame column 1 are temporarily fixed through the bolt in the construction, and the temporary support is not needed, so that the time and the cost are saved.

[0047] In some embodiments, as shown in Figures 4 to 6 The steel strip connecting piece 102 includes a plurality of vertical beams 1023 and a plurality of horizontal beams 1024, the plurality of vertical beams 1023 and the plurality of horizontal beams 1024 are crosswise welded to form a cubic frame structure, and the cubic frame structure has a plurality of spaces.

[0048] When prefabricating the steel strip connectors 102 in the factory, appropriate specifications of steel materials such as steel plates and structural steel can be selected for the vertical beams 1023 and horizontal beams 1024. First, according to the planned crisscrossing layout, the vertical beams 1023 and horizontal beams 1024 are positioned and placed, for example, first assembling them into multiple grid-like structures, and then building multiple layers upwards to form a three-dimensional structure. Next, using welding technology, each intersection of the vertical beams 1023 and horizontal beams 1024 is firmly welded together, gradually constructing a cuboid frame structure. At this point, multiple spaces are naturally formed inside the cuboid frame structure; these spaces are used for the longitudinal reinforcement 1011 and stirrups that subsequently pass through the frame column body 101.

[0049] This cuboid frame structure, constructed through crisscrossing welding, possesses high structural strength and stability. As a key component of the precast frame column 1, the robust steel strip connectors 102 better coordinate with the frame column body 101 to bear various loads, enhancing the overall load-bearing capacity of the precast frame column 1. The steel strip connectors 102 are welded from steel plates or structural steel sections, eliminating the need for anchor bars or other anchoring measures, thus avoiding welding between the steel plates and reinforcing bars and reducing welding complexity. Secondly, the multiple internal spaces provide orderly passageways for the longitudinal reinforcement 1011 and stirrups. Compared to the chaotic arrangement of reinforcing bars in the node areas of traditional structures, this design significantly improves the dense reinforcement situation in the node areas, making the reinforcement arrangement more regular, facilitating construction operations, and effectively improving construction efficiency. Furthermore, the longitudinal reinforcement 1011 and stirrups can directly pass through the cuboid frame structure without cutting or avoiding them, reducing additional processing steps and thus lowering manufacturing costs.

[0050] In some embodiments, such as Figures 4 to 6 , Figures 10 to 13 As shown, the cross-section of the cuboid frame structure is any one of rectangular, cross-shaped, T-shaped, L-shaped, or Z-shaped; the steel strip connector 102 also includes a support plate 1025, and there are multiple support plates 1025, which are evenly distributed on the periphery of the cuboid frame structure; the support plates 1025 are welded to the outer periphery of the cuboid frame structure, and the second connecting part 1021 is welded to the support plate 1025.

[0051] When prefabricating the frame connectors in the factory, the cuboid frame structure can be made into a cross-section of rectangular, cross-shaped, T-shaped, L-shaped, or Z-shaped, depending on the design requirements. This provides a variety of cross-sectional shape options to better adapt to different architectural designs and mechanical requirements. Subsequently, multiple support plates 1025 are prepared and evenly arranged on the periphery of the cuboid frame structure. Welding equipment is used to firmly weld one side of each support plate 1025 to the outer surface of the cuboid frame structure. Finally, the second connecting part 1021 is welded to the side of the support plate 1025 away from the cuboid frame structure, completing the fabrication of the frame connector.

[0052] For example, after being determined as a rectangle, as shown in Figures 4 to 6 A steel material of a proper specification is selected, and the vertical beams 1023 and the horizontal beams 1024 are spliced in a crisscross manner to build a cuboid frame structure with a rectangular cross section. Four support plates 1025 are prepared. The support plates 1025 can be steel plates with a proper thickness, which are uniformly arranged on the four side surfaces of the cuboid frame structure. A welding device can be used to firmly weld one surface of each support plate 1025 to the outer surface of the cuboid frame structure, so that the support plates 1025 are closely connected to the cuboid frame structure. Then, the second connecting part 1021 is welded to the surface of the support plate 1025 that faces away from the cuboid frame structure.

[0053] The welding of the second connecting part 1021 on the support plate 1025 provides a more stable connecting point for the connection between the prefabricated frame beam 2 and the prefabricated frame column 1. The support plate 1025 increases the connecting area between the second connecting part 1021 and the cuboid frame structure, so that the connecting part can bear greater tension and shear force, ensuring the reliability of the connection between the prefabricated frame beam 2 and the prefabricated frame column 1, and being conducive to improving the seismic performance and load-carrying capacity of the entire prefabricated frame column 1. The second connecting part 1021 can be multiple, one on each support plate 1025, and the specific arrangement can be determined according to the actual working conditions, which is not limited herein.

[0054] In some embodiments, in the state where the steel strip connector 102 is connected to the frame column body 101, the support plate 1025 is located outside the frame column body 101; the support plate 1025 is arranged in parallel with the longitudinal reinforcement 1011, and the second connecting part 1021 is a plate structure and is arranged perpendicularly to the support plate 1025.

[0055] During the construction process of the prefabricated frame column 1, when the assembly of the frame column body 101 and the steel strip connector 102 is completed, the support plate 1025 is located outside the frame column body 101 and is arranged in parallel with the longitudinal reinforcement 1011 inside the frame column body 101. The second connecting part 1021 is a plate structure and is arranged perpendicularly to the support plate 1025. The plate structure of the second connecting part 1021 can be arranged along the direction in which the longitudinal reinforcement 1011 is arranged.

[0056] When the connection between the prefabricated frame beam 2 and the prefabricated frame column 1 is performed at the construction site, the support plate 1025 is located outside the frame column body 101 and is arranged in parallel with the longitudinal reinforcement 1011. This arrangement not only does not interfere with the arrangement and stress of the longitudinal reinforcement 1011, but also provides additional support for the frame column body 101. In addition, this arrangement effectively avoids the interference between the prefabricated frame beam 2 and the frame column body 101 when the first connecting part of the prefabricated frame beam 2 and the second connecting part 1021 are connected through a specific connector, ensuring the smooth progress of the connection process.

[0057] In some embodiments, the prefabricated frame column 1 is integrally formed by pouring concrete into the frame column body 101 and the steel strip connector 102; the side of the support plate 1025 facing away from the cuboid frame structure is exposed outside the concrete.

[0058] The longitudinal reinforcement 1011 and the stirrup of the frame column body 101 are passed through the space of the steel strip connector 102, so that the steel strip connector 102 is preliminarily assembled with the frame column body 101. Then, the assembled components are placed in a mold, and the frame column body 101 and the steel strip connector 102 are integrally formed by pouring concrete. During pouring, the side of the support plate 1025 facing away from the cuboid frame structure is exposed outside the concrete, facilitating subsequent connection operations with the prefabricated frame beam 2.

[0059] The frame column body 101 and the steel strip connector 102 are integrally formed by pouring concrete, which enhances the overall structural strength and stability of the prefabricated frame column 1. This integrally formed pouring method reduces the on-site splicing process and reduces the quality risks that may occur during the construction process due to multiple splicing, which is beneficial to ensuring the overall quality of the prefabricated frame column 1. The side of the support plate 1025 exposed outside the concrete provides a clear and easy-to-operate connection point for subsequent connection with the prefabricated frame beam 2, allowing construction personnel to more conveniently butt joint the first connection part of the prefabricated frame beam 2 with the second connection part 1021 on the support plate 1025, thereby improving construction efficiency.

[0060] In some embodiments, as shown in Figures 1 to 3 The stirrup includes a ring-shaped stirrup 1013 and a tension bar 1012. The ring-shaped stirrup 1013 is sleeved on the outer periphery of the longitudinal reinforcement 1011, and the tension bar 1012 is arranged inside the longitudinal reinforcement 1011 and connected with the longitudinal reinforcement 1011. The cross section of the frame column body 101 is in any one of a rectangular shape, a cross shape, a T shape, an L shape, and a Z shape. At least part of the ring-shaped stirrup 1013 is arranged inside the cuboid frame structure.

[0061] Since the steel strip connector 102 is composed of the horizontal beam 1024 and the vertical beam 1023, and part of the stirrup is in a ring shape, it is not possible to directly arrange the ring-shaped stirrup 1013 of the node domain inside the cuboid frame structure of the steel strip connector 102 during the production of the prefabricated frame column 1. Therefore, the ring-shaped stirrup 1013 needs to be placed in place in advance before the cuboid frame structure is welded.

[0062] In the assembly stage, the longitudinal bars 1011 and the stirrups 1012 of the frame column body 101 are first passed through the space of the steel lath connector 102, so that the stirrups 1012 and the longitudinal bars 1011 intersect with each other. Then, a plurality of ring-shaped stirrups 1013 are successively sleeved on the outer periphery of the longitudinal bars 1011, and the ring-shaped stirrups 1013 are firmly connected with the longitudinal bars 1011 and the stirrups 1012 by welding or binding, thereby building a three-dimensional stable steel reinforcement framework system, as shown in FIG. 8. The cross section of the three-dimensional frame can be one of a rectangle, a cross, a T shape, an L shape and a Z shape, which can be selected to match the cuboid frame structure, thereby meeting the diversified requirements of different architectural designs for space layout and structural stress. Figures 10 to 13 After the above combination is completed, the concrete pouring operation is performed, so that the frame column body 101 and the steel lath connector 102 are fused into a complete prefabricated frame column 1.

[0063] The steel reinforcement framework composed of the ring-shaped stirrups 1013, the longitudinal bars 1011 and the stirrups 1012 is very stable, and part of the ring-shaped stirrups 1013 is located in the cuboid frame structure, so that the frame column body 101 and the steel lath connector 102 are closely connected. In this way, the entire structure has stronger synergistic working capacity when bearing the load, and the overall integrity and stability of the structure are greatly improved. In particular, the ring-shaped stirrups 1013 located in the cuboid frame structure can effectively constrain the concrete and steel at the node, and can significantly reduce the deformation of the node area and enhance the seismic performance of the structure when subjected to external forces such as earthquakes.

[0064] In some embodiments, the support plate 1025 has a preset distance between the two side edges parallel to the longitudinal bars 1011 and the first ring-shaped stirrups 1013 close to the side edges.

[0065] When the frame column body 101 and the steel lath connector 102 are assembled, the support plate 1025 is ensured to have a specific preset distance between the two side edges parallel to the longitudinal bars 1011 and the first ring-shaped stirrups 1013 close to the side edges. The preset distance can be calculated according to the design, for example, 50 mm, to meet the requirements of structural performance and construction process. Reserving the preset distance avoids the conflict between the support plate 1025 and the ring-shaped stirrups 1013 in the spatial position, facilitates the accurate installation of each component by the construction personnel during the assembly process, and improves the construction efficiency.

[0066] The prefabricated frame column with a steel lath connector provided by the embodiments of the present application has the following processing method:

[0067] To manufacture the prefabricated frame beam 2, appropriate steel materials can be selected to process the flanges 201 and the web 202, and the web 202 is spliced and welded into an I-shaped frame, and a plurality of bolt holes are formed as the first connecting holes.

[0068] The fabrication of precast frame column 1 includes the fabrication of steel strip connector 102 and frame column body 101.

[0069] Steel strip connectors 102 are fabricated by welding vertical beams 1023 and horizontal beams 1024 in a crisscross pattern using steel plates and structural steel, forming a cuboid frame structure with multiple spaces. Multiple support plates 1025 are evenly welded around the perimeter of the structure, and second connecting parts 1021 with multiple second connecting holes 1022 are welded to the outside of the support plates 1025.

[0070] Fabricate the main frame column 101, arrange longitudinal reinforcement 1011 and tie bars 1012 according to the design, and fabricate annular stirrups 1013. Before welding the cuboid frame structure, place some of the annular stirrups 1013 inside. The longitudinal reinforcement 1011 and tie bars 1012 pass through the space of the steel strip connector 102, connect with the steel strip connector 102, and are pre-embedded in the node area. The annular stirrups 1013 are fitted around the outer periphery of the longitudinal reinforcement 1011 and welded or tied with the longitudinal reinforcement 1011 and tie bars 1012 to form a rectangular steel reinforcement skeleton. Then, place the main frame column 101 and the steel strip connector 102 into the mold, pour concrete to form a single piece, ensuring that one side of the support plate 1025 is exposed.

[0071] The precast frame column 1 is hoisted to the designated location on the construction site and secured. The precast frame beam 2 is hoisted to the design position, and the first connecting hole of the first connecting part of the precast frame beam 2 is aligned with the second connecting hole 1022 of the second connecting part 1021 of the precast frame column 1. Bolts and other connectors are used to pre-connect the beams, completing the initial fixation. The flange 201 of the precast frame beam 2 is welded to the support plate 1025 exposed outside the concrete on the precast frame column 1. The connecting bolts are then tightened, and fine aggregate concrete is poured into the joints and exposed connectors to complete the construction.

Then, the installation of the assembled frame structure is started, the prefabricated frame column 1 is hoisted to the designated position by using a crane and the like, and the prefabricated frame column 1 is fixed by means of a foundation embedded part and the like. Then, the prefabricated frame beam 2 is hoisted, and the first connecting part of the prefabricated frame beam 2 and the second connecting part 1021 of the prefabricated frame column 1 are connected by a connecting piece to realize pre-connection by sequentially passing through the first connecting hole and the second connecting hole 1022.

[0076] By prefabricating the prefabricated frame column 1 and the prefabricated frame beam 2 in the factory, the work amount in the assembled frame structure is reduced. The construction site only needs to carry out simple assembly and welding work, compared with the traditional cast-in-place construction method, the construction period is greatly shortened, and the progress of the building system is accelerated.

[0077] In some embodiments, the prefabricated frame beam 2 includes a flange 201 and a web 202, the flange 201 and the web 202 are tailor-welded to form an I-shaped frame, and the web 202 is a first connecting part; in the state that the first connecting part is connected with the second connecting part 1021, the flange 201 is welded with the support plate 1025 of the steel strip connecting piece 102.

[0078] In the prefabrication stage, appropriate steel materials can be selected to process the flange 201 and the web 202, and the flange 201 and the web 202 are tailor-welded to form an I-shaped frame by a welding process, at this time the web 202 serves as a first connecting part. When arriving at the construction site, the first connecting part (web 202) of the prefabricated frame beam 2 and the second connecting part 1021 of the prefabricated frame column 1 can be connected by a specific connecting piece to complete the preliminary fixation. Subsequently, since one side of the support plate 1025 is exposed outside the concrete, the flange 201 of the prefabricated frame beam 2 can be welded with the support plate 1025 on the prefabricated frame column 1. Finally, the bolts are finally tightened. After the above work is completed, fine stone concrete is poured into the joints and exposed connecting parts to complete the construction.

[0079] Through the connection of the web plate 202 (the first connecting part) and the second connecting part 1021 and the welding of the flange 201 and the support plate 1025, a multi-position collaborative force connection system is formed, which greatly enhances the connection strength between the prefabricated frame beam 2 and the prefabricated frame column 1. From the perspective of construction operation, the welding of the flange 201 and the support plate 1025 is relatively intuitive and easy for construction personnel to master while ensuring the connection strength, thereby improving the on-site construction efficiency. At the same time, the steel strip connecting piece 102 is not exposed, and there is no need for corrosion and fireproofing treatment, so that the construction cost and maintenance cost are lower than those of the traditional steel structure.

[0080] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
