Description

Technical Field

[0001] This invention specifically relates to a highly stable prefabricated assembly component and its installation method, and pertains to the field of building structural component technology. Background Technology

[0002] Prefabricated construction, through factory-prefabricated components and on-site assembly, significantly improves construction efficiency and reduces pollution, becoming a core direction of building industrialization. Especially in large-scale infrastructure, the connection stability and seismic performance of prefabricated components are key technologies. However, existing assembly methods mostly involve assembling multiple templates of different shapes into square components on-site, resulting in low on-site assembly efficiency. Some factories directly prefabricate very large structures, which are inconvenient for vehicle transport or manual handling, leading to high difficulty and significantly increased costs for manual handling. Furthermore, existing components form a closed, integrated structure after assembly, making partial disassembly impossible. Inspecting the internal concrete pouring quality or steel reinforcement corrosion requires damaging the entire structure, increasing maintenance costs and affecting the building's lifespan. Therefore, our company needs to provide a highly stable prefabricated component and its installation method to improve upon existing technologies. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a highly stable prefabricated assembly component and its installation method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a highly stable prefabricated assembly component, including an irregularly shaped base frame, and a left folding template and a right folding template rotatably installed on the left and right sides of the irregularly shaped base frame. Both the left and right folding templates can rotate toward the center to achieve folding and unfolding or the ends are relatively close to each other, so that the irregularly shaped base frame, the left folding template and the right folding template form a triangular support structure as a whole, and a triangular inner filling cavity is formed on the inner side.

[0005] The right and left folding templates have contact openings for hanging the crane hook and for injecting grout into the triangular filling cavity.

[0006] Preferably, the bottom of the left folding template is connected to a left rotating shaft and is rotatably connected to the left side of the irregular bottom frame through the left rotating shaft. The bottom of the right folding template is connected to a right rotating shaft and is rotatably connected to the right side of the irregular bottom frame through the right rotating shaft. The position of the left rotating shaft is higher than the horizontal height of the right rotating shaft, and the width of the left folding template is smaller than the width of the right folding template. The front side of the irregular bottom frame corresponding to the left and right rotating shafts is provided with a first inner slot, and the rear side of the irregular bottom frame corresponding to the left and right rotating shafts is provided with a first insert block that can be assembled and inserted into the first inner slot.

[0007] Preferably, the outer sides of the irregular bottom frame, the right folding template, and the left folding template are all provided with inner groove surfaces, and the front and rear sidewalls of the inner groove surfaces are provided with corresponding first longitudinal connecting holes for bolting two adjacent prefabricated components together.

[0008] Preferably, the right folding template and the left folding template have relatively fitting oblique contact surfaces at their ends, and the oblique contact surfaces have outwardly communicating transverse connecting holes in the middle, for locking the ends of the right folding template and the left folding template together.

[0009] Preferably, an inner steel mesh is provided inside the inner filling cavity to support the right folding template and the left folding template. The inner steel mesh includes multiple vertically arranged longitudinal steel bars and multiple transverse steel bars tied with steel wires on the upper side of the longitudinal steel bars. The two ends of the transverse steel bars are respectively in close contact with the opposite side of the right folding template and the left folding template.

[0010] Preferably, the irregular bottom frame, the right folding template, and the left folding template are respectively equipped with a front cover plate and a rear cover plate for sealing the inner filling cavity on their front and rear sides. The front cover plate is provided with a second insert block adapted to be inserted into the first inner slot, and the rear cover plate is provided with a second inner slot adapted to be provided with the first insert block. The edges of the front cover plate and the rear cover plate are respectively provided with a second longitudinal connecting hole corresponding to the first longitudinal connecting hole, and are connected by bolts.

[0011] Preferably, the front cover plate and the rear cover plate have steel bar holes in the middle, through which longitudinal steel bars pass, and the longitudinal steel bars on the outside of the front cover plate and the rear cover plate are connected to anchors.

[0012] Preferably, a handle is installed on one side of the irregularly shaped bottom frame.

[0013] Preferably, a magnetic block is installed on the inner groove surface of the outer side of the left folding template, and when the right folding template is stacked on the left folding template, they are magnetically connected to each other through the magnetic block.

[0014] It also includes a method for installing highly stable prefabricated components, which comprises the following construction steps:

[0015] S1. Component folding and transportation stage: When folding for use, fold the left folding template on the left side of the irregular bottom frame towards the middle and place it on the upper side of the irregular bottom frame. Then fold the right folding template on the right side of the irregular bottom frame and place it on the left folding template. Since the right rotation axis and the left rotation axis are one plate position apart in height, the mating surfaces of the right folding template and the left folding template can fit together and contact each other when stacked, and they will attract each other under the action of the magnetic block. At this time, the entire folded component can be lifted and placed on site by the handle, or the folded components can be stacked together for storage and transportation.

[0016] S2. Component unfolding stage: Similarly, when the folded component is transported to the site, the right folding template is first flipped up, and then the left folding template is flipped up, so that the oblique contact surfaces of the right folding template and the left folding template come into contact with each other, and the transverse connecting holes are aligned with the corresponding locking bolts, so that the irregular bottom frame, the left folding template and the right folding template form a triangular support structure as a whole, and a triangular inner filling cavity is formed on the inside.

[0017] S3. Assisted hoisting stage: The external crane hook is used to hang the grouting opening, and the unfolded components are hoisted to the construction position one by one. Two adjacent components are initially assembled by inserting the first insert block into the first inner slot. Then, the first longitudinal connecting holes of the inner slot sidewall of the irregular bottom frame, the right folding template and the left folding template are locked together with bolts, so that each position has an individual locking structure. The right folding template or the left folding template can be disassembled and opened separately later.

[0018] S4. Reinforcing bar laying stage: After the above components are assembled, an inner reinforcing bar mesh is laid in the inner filling cavity. The inner reinforcing bar mesh is formed by placing multiple transverse reinforcing bars on the longitudinal reinforcing bars and binding them with steel wire. The longitudinal reinforcing bars need to pass through the reinforcing bar holes of the front cover plate and the rear cover plate, while the two ends of the transverse reinforcing bars are pressed against the inside of the right folding template and the left folding template. When multiple components are spliced ​​together for a long time, the bolts on the right folding template or the left folding template of the component at the designated position are removed individually to adjust or reinforce the internal transverse reinforcing bars.

[0019] S5. Closing stage: The inner filling cavity is closed by installing the front cover plate and the rear cover plate at the front and rear ends of the assembled component, respectively. During operation, it is only necessary to insert the second insert of the front cover plate into the first inner slot at the front end of the component, and the second inner slot of the rear cover plate is fitted into the first insert at the end of the component. The second longitudinal connecting holes of the front cover plate and the rear cover plate are locked with the first longitudinal connecting holes by bolts. Then, the longitudinal steel bars that pass through the steel bar holes are fixed with anchors.

[0020] S6. Concrete pouring stage: The grout is injected into the inner filling cavity by aligning the material pipe of the concrete pouring machine with the pouring opening and solidifying with the inner steel mesh.

[0021] S7. Concrete Inspection and Repair Stage: After the concrete has set, according to the usage requirements, the bolts on the right or left folding template of the designated component are removed individually, and the right or left folding template is flipped open to inspect or repair the concrete in the designated area.

[0022] By adopting the above technical solution, the present invention has the following advantages:

[0023] The invention has a simple and ingenious structure. By rotating and setting the right folding template and the left folding template on the left and right sides of the irregular base frame respectively, they can be folded and placed together to facilitate the single-handed operation of construction personnel. The folded components can also be stacked on top of each other, thereby reducing the space occupied and further facilitating the transportation and use of the components. Therefore, manual portable transportation is achieved through hinges or modular disassembly, reducing mechanical dependence.

[0024] Furthermore, when the ends of the right-folding template and the left-folding template are close together, the irregular bottom frame, the left-folding template, and the right-folding template can form a triangular support structure as a whole, and a triangular inner filling cavity is formed on the inside. This triangular structure provides stable support, and combined with the concrete grout and inner steel mesh poured later, it can greatly improve the overall support strength and stability, simplify the connection logic, ensure seismic performance, and improve assembly efficiency.

[0025] Furthermore, a hoisting and grouting opening is provided at the relative contact point between the right folding template and the right rotating shaft for hanging the crane hook and for injecting grout into the triangular filling cavity. This hoisting and grouting opening serves a dual purpose, facilitating both hanging and grouting operations.

[0026] Meanwhile, due to the matching first inner slot and first insert block set at the front and back of the irregular bottom frame, two adjacent components can be initially inserted together, which improves the overall vertical support strength, makes the structure stable, assembles quickly, and is highly flexible in use. In addition, inner groove surfaces and transverse connection holes are opened on both the right folding template and the left folding template, and the first longitudinal connection hole is set on the side wall of the inner groove surface. This not only facilitates the overall bolting of the components, but also allows one right folding template or left folding template to be removed separately later, allowing non-destructive disassembly of local components, and realizing post-concrete quality monitoring and targeted repair.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figure 1-8 As shown in the figure, this invention provides a highly stable prefabricated assembly component, including an irregularly shaped base frame 1, a left folding template 3 and a right folding template 2 rotatably mounted on the left and right sides of the irregularly shaped base frame 1, and a handle 8 installed on one side of the irregularly shaped base frame 1. Both the left folding template 3 and the right folding template 2 can rotate towards the center to achieve folding and unfolding or to have their ends tightly pressed together. When folded, the left folding template 3 and the right folding template 2 can reduce the area and space occupied, making it convenient for manual lifting by holding the handle 8 to the required construction position. The folded component can also be stacked, bringing great convenience to storage and transportation. When the ends of template 3 and right fold template 2 are tightly attached to each other, the irregular bottom frame 1, left fold template 3 and right fold template 2 form a triangular support structure, and a triangular inner filling cavity 5 is formed on the inside. This triangular support structure can improve the overall support strength and stability of the structure. The contact part between the ends of right fold template 2 and left fold template 3 is provided with a hoisting opening 4 for hanging the crane hook and for injecting grout into the triangular inner filling cavity 5. After the grout is injected into the inner filling cavity 5 and the concrete sets, the dual support of steel structure and concrete is achieved, which can further improve the overall quality and structural strength of the component.

[0039] Specifically, the bottom of the left folding template 3 is connected to a left rotating shaft 31, which is rotatably connected to the left side of the irregular base frame 1. The bottom of the right folding template 2 is connected to a right rotating shaft 21, which is rotatably connected to the right side of the irregular base frame 1. The position of the left rotating shaft 31 is higher than the horizontal height of the right rotating shaft 21, and is higher than the thickness of the left folding template 3 by one body length. The width of the left folding template 3 is smaller than the width of the right folding template 2, so as to achieve the flipping and folding effect of the left folding template 3 and the right folding template 2. A damping rubber ring can be fitted on the outside of the left rotating shaft 31 and the right rotating shaft 21 to make tight contact with the irregular base frame 1 and avoid leakage during later grouting.

[0040] The front side of the irregularly shaped base frame 1 corresponding to the left rotating shaft 31 and the right rotating shaft 21 is provided with a first inner slot 7, and the rear side of the irregularly shaped base frame 1 corresponding to the left rotating shaft 31 and the right rotating shaft 21 is provided with a first insert block 71 that can be assembled and inserted into the first inner slot 7. This arrangement allows the two components to be initially connected by inserting the first insert block 71 into the first inner slot 7. This insertion method not only serves to align the screws between the components, but also improves the mechanical resistance to lateral displacement, and improves the resistance to shear and pressure.

[0041] In the above technical solution, the outer sides of the irregular bottom frame 1, the right folding template 2 and the left folding template 3 are all provided with inner groove surfaces 6, and the front and rear side walls of the inner groove surfaces 6 are provided with corresponding first longitudinal connection holes 61. When the first longitudinal connection holes 61 of the irregular bottom frame 1, the right folding template 2 and the left folding template 3 of two adjacent precast components correspond, they can be connected by bolts. Moreover, the right folding template 2 and the left folding template 3 are connected separately. Therefore, one of the right folding template 2 or the left folding template 3 can be removed separately and rotated outward to monitor the quality of the concrete and make targeted repairs. Furthermore, the disassembly of a local position does not affect the support of the overall structure.

[0042] Furthermore, the right folding template 2 and the left folding template 3 are provided with relatively fitting oblique contact surfaces 90 at their ends, and the oblique contact surfaces 90 are provided with outwardly communicating transverse connecting holes 9 in the middle, which are used to lock the ends of the right folding template 2 and the left folding template 3 together, thereby improving the stability of the initial component assembly and forming a stable triangular support structure. The bolts of the transverse connecting holes 9 can also be disassembled and installed later to facilitate the opening of the right folding template 2 or the left folding template 3.

[0043] In this embodiment, an inner steel mesh 51 is also provided inside the inner filling cavity 5 to support the right folding template 2 and the left folding template 3. The inner steel mesh 51 includes multiple vertically arranged longitudinal steel bars 52 and multiple transverse steel bars 53 tied with steel wires on the upper side of the longitudinal steel bars 52. In this way, after the concrete is poured later, it will solidify with the inner steel mesh 51, which can improve the quality and strength of the overall component. Moreover, the inner wall panel of the inner filling cavity 5 can be pre-coated with a self-cleaning glaze layer, such as ceramic tile glaze, which can reduce adhesion and improve demolding. It is also easier to open the left folding template 3 or the right folding template 2 separately later.

[0044] The transverse reinforcing bars 53 are in close contact with the opposite sides of the right folding template 2 and the left folding template 3, respectively, to strengthen the support. The front cover plate 10 and the rear cover plate 11 for sealing the inner filling cavity 5 are respectively installed on the front and rear sides of the irregular bottom frame 1, the right folding template 2 and the left folding template 3. The front cover plate 10 is provided with a second insert 101 adapted to be inserted into the first inner slot 7, and the rear cover plate 11 is provided with a second inner slot 111 adapted to be provided in the first insert 71. The edges of the front cover plate 10 and the rear cover plate 11 are respectively provided with second longitudinal connecting holes 12 corresponding to the first longitudinal connecting hole 61, and are connected by bolts. Therefore, the front cover plate 10 and the rear cover plate 11 can be installed on the front and rear sides of the component to seal the inner filling cavity 5 and improve the support effect on the front and rear sides of the component.

[0045] Furthermore, the front cover plate 10 and the rear cover plate 11 have steel bar holes 13 through which the longitudinal steel bars 52 pass to support the fixed position of the longitudinal steel bars 52. The longitudinal steel bars 52 on the outside of the front cover plate 10 and the rear cover plate 11 are connected to the anchors 14, and the front cover plate 10 and the rear cover plate 11 are connected together by the longitudinal steel bars 52. The front cover plate 10 and the rear cover plate 11 are also connected to the irregular bottom frame 1, the right folding template 2 and the left folding template 3 to form an overall high-strength support structure.

[0046] Since the right folding template 2 is stacked on top of the left folding template 3, when the entire component is lifted by holding the handle 8, the right folding template 2 is vertically placed on the outside of the left folding template 3, which serves to limit the outward flipping of the left folding template 3. In order to further prevent the left folding template 3 and the right folding template 2 from flipping outward when they are folded, a magnetic block 62 is installed on the inner groove surface 6 on the outside of the left folding template 3. When the right folding template 2 is stacked on the left folding template 3, they are magnetically connected to each other through the magnetic block 62, which improves the stability of use.

[0047] An installation method for highly stable prefabricated components includes the following specific construction steps:

[0048] S1. Component folding and conveying stage: When folding for use, fold the left folding template 3 on the left side of the irregular base frame 1 towards the middle and place it on the upper side of the irregular base frame 1. Then fold the right folding template 2 on the right side of the irregular base frame 1 and place it on the left folding template 3. Since the right rotation shaft 21 and the left rotation shaft 31 are one plate position apart in height, the mating surfaces of the right folding template 2 and the left folding template 3 can fit together and contact each other when stacked, and they are attracted to each other under the action of the magnetic block 62. At this time, the entire folded component can be lifted and placed on site through the handle 8, or the folded components can be stacked together for storage and transportation.

[0049] S2. Component unfolding stage: Similarly, when the folded component is transported to the site, the right folding template 2 is first flipped up, and then the left folding template 3 is flipped up, so that the oblique contact surfaces 90 of the right folding template 2 and the left folding template 3 come into contact with each other, and the transverse connecting holes 9 are aligned with the corresponding locking bolts, so that the irregular bottom frame 1, the left folding template 3 and the right folding template 2 form a triangular support structure as a whole, and a triangular inner filling cavity 5 is formed on the inside.

[0050] S3. Assisted hoisting stage: The external crane hook is used to hang the hoisting opening 4, and the unfolded components are hoisted to the construction position one by one. Two adjacent components are initially assembled by inserting the first insert block 71 into the first inner slot 7. Then, the first longitudinal connecting holes 61 on the inner groove surface 6 of the irregular bottom frame 1, the right folding template 2 and the left folding template 3 are locked together with bolts, so that each position has an individual locking structure. The right folding template 2 or the left folding template 3 can be disassembled and opened separately later.

[0051] S4. Reinforcing bar laying stage: After the above components are assembled, an inner reinforcing bar mesh 51 is laid in the inner filling cavity 5. The inner reinforcing bar mesh 51 is formed by multiple transverse reinforcing bars 53 placed on longitudinal reinforcing bars 52 and tied with steel wire. The longitudinal reinforcing bars 52 need to pass through the reinforcing bar holes 13 of the front cover plate 10 and the rear cover plate 11, while the two ends of the transverse reinforcing bars 53 are pressed against the inner side of the right folding template 2 and the left folding template 3. When multiple components are spliced ​​for a long time, the bolts on the right folding template 2 or the left folding template 3 of the component at the designated position are removed to adjust or reinforce the internal transverse reinforcing bars 53.

[0052] S5. Closing stage: The inner filling cavity 5 is closed by installing the front cover plate 10 and the rear cover plate 11 at the front and rear ends of the assembled component, respectively. During operation, it is only necessary to insert the second insert 101 of the front cover plate 10 into the first inner slot 7 at the front end of the component, and the second inner slot 111 of the rear cover plate 11 is fitted into the first insert 71 at the end of the component. The second longitudinal connecting holes 12 of the front cover plate 10 and the rear cover plate 11 are locked with the first longitudinal connecting hole 61 by bolts. Then, the longitudinal steel bar 52 that passes through the steel bar hole 13 is fixed by the anchor 14.

[0053] S6. Concrete pouring stage: By aligning the material pipe of the concrete pouring machine with the pouring opening 4, grout is poured into the inner filling cavity 5 and solidified with the inner steel mesh 51.

[0054] S7. Concrete Inspection and Repair Stage: After the concrete has set, depending on the usage requirements, the bolts on the right folding template 2 or left folding template 3 of the designated component are removed individually, and the right folding template 2 or left folding template 3 is flipped open to inspect or repair the concrete in the designated area.

[0055] The above embodiments illustrate and describe the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

Steel bar laying stage: the inner steel bar net (51) is laid in the inner filling cavity (5), the inner steel bar net (51) is formed by placing a plurality of transverse steel bars (53) on the longitudinal steel bars (52) and binding them with steel wires, the longitudinal steel bars (52) need to penetrate the steel bar holes (13) of the front cover plate (10) and the rear cover plate (11), and the two ends of the transverse steel bars (53) abut against the inner sides of the right folding template (2) and the left folding template (3), when a plurality of components are connected to be long, the bolts on the right folding template (2) or the left folding template (3) of the specified position component are separately disassembled, and the internal transverse steel bars (53) are adjusted or reinforced. S5. Closed stage: by installing the front cover plate (10) and the rear cover plate (11) on the front end and the rear end of the assembled component, the inner filling cavity (5) is closed. When operating, only need to insert the second plug block (101) of the front cover plate (10) into the first inner plug slot (7) at the front end of the component, and the second inner plug slot (111) of the rear cover plate (11) is sleeved on the first plug block (71) at the end of the component, and then the second longitudinal connecting hole (12) of the front cover plate (10) and the rear cover plate (11) is locked with the first longitudinal connecting hole (61) through the bolt, and then the longitudinal steel (52) inserted out of the steel hole (13) is fixed by the anchor (14); S6. Concrete pouring stage: by aligning the material pipe of the concrete pouring machine with the hoisting pouring opening (4), the inner filling cavity (5) is poured with slurry and coagulated with the inner steel mesh (51); S7. Concrete detection and repair stage: after the concrete coagulates, according to the use requirement, the bolt on the right folding formwork (2) or the left folding formwork (3) of the component at the specified position is separately disassembled, the right folding formwork (2) or the left folding formwork (3) is turned over and opened, and the concrete at the specified position is detected or repaired for the post-construction operation.
