[0002] In the construction of prefabricated concrete structures, traditional beam-column joint connections often use cast-in-place or pre-embedded fixed connectors, which presents the following problems: Cast-in-place construction requires the erection of a large number of supports and formwork, which is complicated, inefficient, and traditional support systems occupy a lot of space, affecting the on-site work flow. Pre-embedded connectors are encased in concrete after casting and cannot be disassembled and recycled, resulting in high material loss and construction costs, which violates the requirements of green construction. The accuracy and stability of node connections depend on on-site manual operation, which is prone to installation deviations and affects the overall safety performance of the structure.

[0003] To address the need for supportless construction of box-type composite slab-precast beam systems, existing connecting components cannot simultaneously meet the requirements of temporary load-bearing, rapid installation, and repeated reuse.

[0019] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0020] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0021] Secondly, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0022] In the construction of prefabricated concrete structures, traditional beam-column joint connections often use cast-in-place or pre-embedded fixed connectors, which presents the following problems: Cast-in-place construction requires the erection of a large number of supports and formwork, which is complicated, inefficient, and traditional support systems occupy a lot of space, affecting the on-site work flow. Pre-embedded connectors are encased in concrete after casting and cannot be disassembled and recycled, resulting in high material loss and construction costs, which violates the requirements of green construction. The accuracy and stability of node connections depend on on-site manual operation, which is prone to installation deviations and affects the overall safety performance of the structure.

[0023] To address the aforementioned technical issues, this application provides a reusable support system for box-type composite slab-precast beam systems. The system supports the ends of the precast beams via column-side fixed bases and prevents overturning through anti-overturning components. Temporary independent supports further support the precast beams. The beam-side fixed bases are detachably mounted on both sides of the precast beams to support the box-type composite slabs. This significantly reduces on-site erection and dismantling procedures, shortens the construction cycle, meets the rapid assembly requirements of box-type composite slab-precast beam systems, and utilizes detachable connections, allowing components to be completely disassembled and reused, reducing material waste, lowering overall project costs, and aligning with green building and circular economy concepts.

[0024] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Please refer to Figures 1-6This application provides a reusable support system for a box-type composite slab 4-precast beam 2 system, including a column-side fixed base 5, an anti-overturning member 6, a beam-side fixed base 7, and a temporary independent support 3. The column-side fixed base 5 is detachably mounted on the top of the frame column 1 to support the precast beam 2; the anti-overturning member 6 is detachably connected to the end of the precast beam 2, and the anti-overturning member 6 is detachably connected to the column-side fixed base 5; the beam-side fixed base 7 is detachably mounted on both sides of the precast beam 2 to support the box-type composite slab 4; and the temporary independent support 3 is used to support the precast beam 2.

[0026] The construction method is as follows: During the construction of the prefabricated concrete structure, the frame column 1 is constructed first. During the reinforcement binding stage of frame column 1, pre-drilled holes are set on opposite sides, and the column-side fixing base 5 is precisely positioned with the pre-drilled holes on frame column 1. After the concrete of frame column 1 reaches its design strength, high-strength bolts are used to pass through the first pre-drilled holes to fix the column-side fixing base 5. Before hoisting the precast beam 2, the anti-overturning component 6 and the beam-side fixing base 7 are fixed to both ends and the middle of the precast beam 2 using high-strength bolts. The temporary independent support 3 is fixed to the floor or ground by adjustable tie rods 34, arranged individually or in multiple pieces. The height of the adjustable base 32 is adjusted so that the temporary independent support 3 supports the precast beam 2. The precast beam 2 is hoisted to the design position, the anti-overturning component 6 is aligned with the column-side fixing base 5, and connected with high-strength bolts to complete the temporary fixing of the joint. The box-type composite slab 4 is hoisted to the designed position and placed on the fixed base 7 on the side of the beam, forming a temporary load-bearing system to replace traditional supports and formwork, ensuring structural stability during the laying and reinforcement binding stages of the box-type composite slab 4. The upper layer of reinforcement is then bound, and concrete is poured. After the concrete reaches 100% of its design strength, the high-strength bolts are loosened, and all connecting components are removed from the joints. Reserved holes are repaired, residual concrete is cleaned from the surface, and the slab is then transported to the upper structure for repeated installation and reuse.

[0027] This application supports the ends of the precast beam 2 using column-side fixed bases 5, prevents overturning of the precast beam 2 using anti-overturning components 6, and provides additional support for the precast beam 2 using temporary independent supports 3. Beam-side fixed bases 7 are detachably installed on both sides of the precast beam 2 to support the box-type composite slab 4. This component bears the self-weight of the composite concrete and construction loads, distributing the loads to the beam and column structures through mechanical transfer, ensuring controllable joint deformation and structural safety. After the concrete strength reaches the design requirements, the detachable connection mechanism is removed, and the component is completely dismantled from the joint. After cleaning and maintenance, it is transported to the next floor or other projects for reuse. This significantly reduces on-site erection and dismantling procedures, shortens the construction cycle, meets the rapid assembly requirements of the box-type composite slab 4-precast beam 2 system, and uses detachable connections, allowing for complete dismantling and reuse of components, reducing material waste, lowering overall project costs, and aligning with green building and circular economy concepts.

[0028] In some embodiments of this application, see Figure 2 and Figure 3 The column-side fixing base 5 includes a support plate 51. The adjacent two sides of the support plate 51 are respectively provided with a plurality of first strip holes 53 and a plurality of second strip holes 54. The frame column 1 is provided with a plurality of through first reserved holes. The positions of the first strip holes 53 and the first reserved holes correspond to each other. The second strip holes 54 are used to connect the anti-overturning component 6.

[0029] The support plate 51 is temporarily fixed to the frame column 1 by passing high-strength bolts sequentially through the first reserved hole and the first strip hole 53. The support plate 51 supports the end of the precast beam 2 and is fixedly connected to the anti-overturning member 6 through the second strip hole 54 to prevent the precast beam 2 from overturning. The support plate 51 has multiple strip holes along its length to accommodate precast beams 2 of different specifications, making it highly versatile and easy to promote large-scale application.

[0030] In some embodiments, see Figure 2 and Figure 3 The cross-sectional shape of the support plate 51 is an inverted L-shape. It can be understood that in some other embodiments of this application, the cross-sectional shape of the support plate 51 may also be C-shaped or other shapes, which is not limited in this application.

[0031] In some embodiments of this application, see Figure 3 The height of the side surface of the support plate 51 (i.e., the surface that fits against the frame column 1) is greater than the width of the top surface, and the first strip-shaped holes 52 are arranged in two rows along the height direction and three columns along the horizontal direction on the side surface of the support plate 51. It can be understood that in other embodiments of this application, the number of the first strip-shaped holes 52 can also be set according to actual needs, and this application does not limit it.

[0032] In some embodiments of this application, see Figure 2 and Figure 3 The column-side fixing base 5 also includes a plurality of first stiffening plates 52, which are spaced apart along the length of the support plate 51. The plurality of first stiffening plates 52 can improve the rigidity of the support plate 51, prevent deformation, and improve the support capacity of the column-side fixing base 5.

[0033] In some embodiments of this application, see Figure 2 and Figure 4 The anti-overturning component 6 includes an L-shaped support plate 61. The L-shaped support plate 61 has a third strip hole 63 and a fourth strip hole 64 on both sides. The end of the precast beam 2 has a second reserved hole corresponding to the position of the third strip hole 63. The fourth strip hole 64 corresponds to the position of the second strip hole 64.

[0034] The precast beam 2 is temporarily fixed to the L-shaped support plate 61 by passing high-strength bolts through the second reserved hole and the third strip hole 63 in sequence. The anti-overturning component 6 is temporarily fixed to the column side fixing base 5 by passing high-strength bolts through the fourth strip hole 64 and the second strip hole 54.

[0035] In some embodiments of this application, see Figure 4 At least two second stiffening plates 62 are provided on the L-shaped support plate 61, and the second stiffening plates 62 are fixedly connected to both sides of the L-shaped support plate 61 respectively. The second stiffening plates 62 can improve the rigidity of the L-shaped support plate 61 and prevent the anti-overturning component 6 from deforming.

[0036] In some embodiments of this application, see Figure 1 and Figure 2 The beam-side fixing base 7 is installed along the length of the precast beam 2. The precast beam 2 has multiple third reserved holes spaced apart along its length. The beam-side fixing base 7 has multiple bolt holes corresponding to the positions of the third reserved holes. High-strength bolts pass through the third reserved holes and the bolt holes on the beam-side fixing base 7 to temporarily fix the beam-side fixing base 7 to the precast beam 2.

[0037] In some embodiments of this application, see Figure 2 The beam-side fixing base 7 is L-shaped, and multiple third stiffening plates 71 are evenly spaced along its length. By setting the third stiffening plates 71, the strength of the beam-side fixing base 7 can be improved, thereby increasing its load-bearing capacity.

[0038] In some embodiments of this application, see Figure 1 and Figure 5 The temporary independent support 3 includes an adjustable base 32 and a support rod 31. The bottom of the support rod 31 is connected to the adjustable base 32, and the top of the support rod 31 is provided with a top plate 33, which is used to support the precast beam 2.

[0039] Specifically, the adjustable base 32 includes multiple bolts and is threadedly connected to the support rod 31. By rotating the bolts, the height of the support rod 31 can be adjusted, thereby adjusting the height of the top plate 33 to support the precast beam 2.

[0040] In some embodiments of this application, see Figure 1 and Figure 5 The temporary independent support 3 also includes multiple adjustable tie rods 34, one end of which is hinged to the support rod 31, and the other end of which is used to fix it to the ground or floor.

[0041] Specifically, multiple adjustable tie rods 34 are symmetrically arranged around the support rod 31. By fixing the adjustable tie rods 34 to the floor or ground, the stability of the support rod 31 can be improved, preventing it from tipping over. It is understood that the length of the adjustable tie rods 34 can be adjusted, thereby adjusting the angle of the adjustable tie rods 34 and their connection position with the floor or ground. In some embodiments, see... Figure 5 The adjustable rod includes a sleeve and two rods. The sleeve has threads, and the two rods have threaded sections connecting to the sleeve, with the two threaded sections rotating in opposite directions. Rotating the sleeve adjusts the relative distance between the two rods, thereby adjusting the overall length. In other embodiments of this application, the adjustable rod 34 can also adopt other structures, as long as it can adjust its own length; this application does not impose any limitations.

[0042] In some embodiments of this application, see Figure 1 and Figure 5 The support rod 31 includes two or more segments, adjacent segments are bolted together by connecting plates 35, and multiple fourth stiffening plates 36 are evenly arranged on the connecting plates 35.

[0043] By setting the support rod 31 into two or more segments and connecting adjacent segments with connecting plates 35 and bolts, the space occupied by a single support rod 31 can be reduced, facilitating installation and transportation. Multiple fourth stiffening plates 36 are evenly arranged on the connecting plate 35 to improve the strength of the connection between adjacent segments and prevent breakage at the connection point.

[0044] In other embodiments of this application, see [reference] Figure 6 The top plate 33 is provided with connecting holes (not shown in the figure), and the anti-overturning member 6 is bolted to the top plate 33 through the connecting holes. Example 1

[0045] Taking a certain underground equipment production and R&D headquarters base project as an example, the project adopts a support-free and formwork-free box-type composite slab-precast beam system, and the beam-column joints adopt the support system of this invention: Prefabrication: Anti-overturning components 6, beam side fixing base 7, column side fixing base 5 and temporary independent support 3 are prefabricated in the factory according to the design drawings, using high-strength steel for welding and forming, and the surface is hot-dip galvanized for anti-corrosion treatment and then sprayed with red / yellow two-color marking paint. On-site installation: During the reinforcement binding stage of frame column 1, pre-drill holes on the opposite side and pre-position the column side fixing base 5; after the concrete of frame column 1 reaches the design strength, use high-strength bolts to fix the column side fixing base 5 through; before hoisting the precast beam 2, fix the anti-overturning component 6 to the beam side fixing base 7 with high-strength bolts through; fix the temporary independent support 3 to the floor or ground through adjustable tie rods 34, with single or multiple rods, and adjust the height of the steel plate base so that the top plate 33 supports the precast beam 2; hoist the precast beam 2, align the anti-overturning component 6 with the column side base positioning slot, and connect them with high-strength bolts to complete the temporary fixing of the node; Construction and turnover: Lay box-type composite slab 4, tie the upper layer of steel bars, and carry out concrete pouring; after the concrete strength reaches 100% of the design strength, loosen the high-strength bolts, remove the connecting components from the joint, repair the reserved holes, clean the residual concrete on the surface, and then transfer it to the upper structure for repeated installation and use. Example 2

[0046] See Figure 6 This embodiment is basically the same as Embodiment 1, with the main difference being: connecting holes are opened on the top plate 33 of the temporary independent support 3, the precast beam 2 is hoisted to the design position, and the anti-overturning component 6 is fastened to the connecting holes on the top plate 33 of the temporary independent support 3 with high-strength bolts. The box-type composite slab 4 is hoisted to the design position and rests on the beam side fixed base 7. The temporary independent support 3 is used to replace the concrete frame column 1. At this time, the column reinforcement, beam reinforcement, and slab reinforcement can be tied and the concrete poured at the same time, which greatly saves construction time. After the concrete strength reaches 100% of the design strength, the high-strength bolts are loosened, the connecting component is removed from the node, the reserved hole is repaired, the residual concrete on the surface is cleaned, and then it is transported to the upper structure for repeated installation and use.

[0047] The second aspect of this application provides a construction method that uses the reusable support system for the box-type composite slab 4-precast beam 2 system provided in the first aspect.

[0048] Since the construction method in this embodiment includes the support system described in any of the above embodiments, the construction method includes the structure and beneficial effects of the reusable support system, which will not be described in detail here.

[0049] This application adopts a support-free design, which significantly reduces on-site erection and dismantling procedures, shortens the construction cycle, and meets the rapid assembly requirements of the box-type composite slab 4-precast beam 2 system. Through rigid connection and stiffening plate construction, the shear and bending bearing capacity of the nodes is improved, reliably ensuring the structural stability during installation and pouring, and reducing construction risks. The use of detachable bolt connection allows the components to be completely disassembled and reused, reducing material waste and lowering the overall project cost, which is in line with the concepts of green building and circular economy. The strip hole and positioning structure can be adapted to precast beam 2 of different specifications, which is highly versatile and facilitates large-scale promotion and application.
