[0043] In existing technologies, full-span support systems require densely packed ground support points, which limits the available space on the construction site and affects the parallel operation of other processes. For example, in the construction of multi-story concrete structures, traditional support systems occupy a large area of ​​ground, making it difficult to carry out material transportation, equipment operation, and other processes simultaneously. Especially in areas with densely packed columns (around 200mm), the arrangement of ground support points further compresses the construction space, leading to reduced work efficiency.

[0044] To address the aforementioned issues and improve high-altitude load-bearing capacity while reducing ground support points, the design concept focuses on utilizing the structural support of the column 200 itself. Traditional solutions rely on ground support, leading to space constraints. Therefore, a solution is proposed that combines a tie rod 1 running through the column 200 with a detachable support component 2 to achieve high-altitude support functionality.

[0045] Therefore, please refer to the following: Figure 1 and Figure 2 This application proposes a support bracket structure 100, which is applied to a concrete structure of building beams and slabs. It includes multiple parallel tie rods 1 for penetrating columns 200; two support components 2 are respectively disposed at both ends of the tie rods 1 and abut against both sides of the columns 200, and the support components 2 are provided with support planes 21; multiple bolts 3 are disposed at both ends of the tie rods 1 for connecting the tie rods 1 and the support components 2.

[0046] The tie rod 1 is a member that penetrates the column 200 and bears bidirectional tensile force. It can be made of high-strength threaded steel and arranged in parallel to form a stable tensile force distribution. The support assembly 2 is a structure that provides a load-bearing plane. It can be a frame formed by welding steel plates, and its support plane 21 is used to connect the Bailey beam. The bolt 3 is a fastener that connects the tie rod 1 and the support assembly 2. It can be a hexagonal bolt, which can be detachably fixed through threaded engagement.

[0047] Specifically, after the tie rod 1 passes through the column 200, the support components 2 are fixed at both ends by bolts 3. The support components 2 abut against the two sides of the column 200, and the load is transferred to the column 200 through symmetrical arrangement. The bolt connection allows the position of the support components 2 to be adjusted to meet the installation requirements of different heights. The parallel arrangement of the tie rods 1 enhances the overall bending stiffness, while the support plane 21 disperses the concentrated load and avoids excessive local stress. During installation, the support components 2 are quickly fixed by bolts 3, without the need for complex welding or pre-embedded parts, simplifying the construction process.

[0048] Through the above technical solutions, this application solves the problem of limited construction space, reduces the need for ground support points, and allows other processes to be carried out in parallel. The bidirectional contact between the support component 2 and the column 200 enhances the anti-overturning capacity, and the parallel arrangement of the tie rods 1 improves the overall load-bearing strength. The bolt connection method simplifies the installation process, enabling rapid positioning and disassembly, and is suitable for construction scenarios of building beams and slabs of different heights.

[0049] like Figure 3 and Figure 5 As shown, this application further proposes a support bracket structure 100 including a plurality of connectors 4. The connectors 4 are located on the side of one support component 2 facing another support component 2. Each connector 4 is provided at one end of a screw. One end of the connector 4 is connected to the screw, and the other end is connected to a bolt 3.

[0050] The connector 4 is a force-transmitting component positioned between the two support components 2. It can be implemented as a conical metal block, with a larger diameter at the end near the bolt 3 and a gradually decreasing diameter at the end further away. This conical design ensures that the tension of the screw is evenly distributed to the bolt 3 through the connector 4, preventing localized stress concentration. The bolt 3 is a fastener used to secure the connector 4 to the support component 2. It can be implemented as a high-strength bolt, locking the connector 4 to the support component 2 through threaded engagement, forming a rigid connection.

[0051] Specifically, the tension of the screw is transmitted to the bolt 3 through the connector 4. The tapered structure of the connector 4 transforms the concentrated load into a distributed load, allowing the stress on the support assembly 2 to diffuse evenly along the surface of the connector 4. The rigid connection between the connector 4 and the screw and bolt 3 constrains the relative displacement between the screw and the support assembly 2, preventing loosening of the connection due to vibration or load changes. Each connector 4 is independently configured for each screw, ensuring that each force transmission path is independent and avoiding load interference between multiple screws.

[0052] Through the above technical solution, this application solves the problem of insufficient connection strength between the screw and the support component 2, ensuring that the connection of the bracket structure does not slip or break when subjected to high loads, and improving the overall stability of the structure.

[0053] This application further proposes that the diameter of the connector 4 gradually decreases in the direction away from the bolt 3.

[0054] The gradually decreasing diameter refers to the continuous or segmented reduction in the cross-sectional dimensions of the connector 4 along the axial direction. This can be achieved using a tapered geometry or a stepped diameter-changing structure. This shape creates a smooth stress gradient distribution in the connector 4 when subjected to axial tensile force. The direction away from the bolt 3 refers to the side of the connector 4 opposite to the fastening end of the bolt 3 during installation. This can be achieved by using a unidirectional tapered connector 4. This directional design ensures that the load transfer path matches the structural strength distribution.

[0055] Specifically, when connector 4 adopts a tapered geometry, its moment of inertia changes continuously along the axial direction, forming mechanical properties similar to a variable cross-section beam. When the tie rod 1 is subjected to tension, the larger cross-section at the root region of connector 4 provides sufficient bending stiffness, while the tapered end reduces local stress peaks. During assembly, the tapered outer contour and the mounting hole of the support component 2 form a self-centering effect, ensuring uniform stress distribution on the contact surface between connector 4 and support component 2.

[0056] The self-centering characteristic of the tapered connector 4 improves the assembly accuracy of the support assembly 2 and the tie rod 1, enabling rapid positioning and installation on the construction site. This design, through proactive optimization of the structural form, improves construction efficiency while ensuring load-bearing reliability.

[0057] This application further proposes that the support assembly 2 includes a support body 22. The support body 22 has mounting holes, through which bolts 3 are inserted.

[0058] Among them, the support body 22 refers to the rigid structural component used to fix the tie rod 1. Specifically, it can be made of welded steel plate or cast metal parts. The mounting holes opened in it are used to constrain the insertion path of the bolt 3 and ensure that the support assembly 2 is aligned with the axis of the tie rod 1.

[0059] Specifically, the support body 22 achieves a rigid connection with the tie rod 1 through the cooperation of the mounting hole and the bolt 3. The diameter of the mounting hole matches the diameter of the bolt 3, for example, by using a clearance fit or a transition fit, so that the bolt 3 can be quickly positioned and locked after being inserted.

[0060] Through the above technical solution, this application solves the problem of difficult positioning of the support component 2 when it is installed on both sides of the column 200. The cooperation between the mounting hole and the bolt 3 ensures that the support component 2 can be quickly aligned and locked.

[0061] This application further proposes a structural assembly of the support body 22 including a mounting block 221, a mounting plate 222, and a reinforcing plate 223. The mounting block 221 has mounting holes, and the mounting plate 222 connects to the top surface of the mounting block 221 and extends outward to form a cantilever structure. The reinforcing plate 223 is disposed on the bottom surface of the mounting plate 222 and connects with the mounting plate 222 and the mounting block 221 to form a triangular support system.

[0062] Among them, mounting block 221 refers to a metal base component with through hole 2231, which provides a reference position for bolt 3 to pass through and be fixed. Mounting plate 222 refers to a horizontally extending plate-like structure, and reinforcing plate 223 refers to a supporting component connected below the cantilever structure. Its right-angled sides are welded to mounting plate 222 and mounting block 221 respectively, which improves the bending resistance through the principle of triangular stability.

[0063] Specifically, bolt 3 passes through the mounting hole of mounting block 221 to achieve a rigid connection between support assembly 2 and tie rod 1. Mounting plate 222 extends outward from the top of mounting block 221 to form a cantilever platform, and reinforcing plate 223 forms a two-way connection structure on the bottom surface of mounting plate 222 to enhance the bonding strength between mounting plate 222 and mounting block 221.

[0064] Through the above technical solutions, this application effectively improves the structural stability of the supporting body 22. The triangular support system formed by the reinforcing plate 223 significantly improves the stress state of the cantilever structure, enabling the supporting bracket to withstand greater construction loads.

[0065] This application further proposes that the supporting body 22 includes two reinforcing plates 223, which are arranged in parallel.

[0066] The two reinforcing plates 223 are plate-shaped components installed on the bottom surface of the mounting plate 222 and connected to the mounting block 221. This feature forms double support points through symmetrical arrangement, increasing the contact area between the mounting plate 222 and the mounting block 221. The parallel arrangement means that the two reinforcing plates 223 are equidistantly distributed along the width direction of the mounting plate 222. This feature ensures that stress is transmitted along two symmetrical axes, avoiding eccentric loading caused by unilateral force application.

[0067] Specifically, when the mounting plate 222 bears the vertical load transmitted by the Bailey beam, the two parallel reinforcing plates 223 respectively transfer the load to both sides of the mounting block 221. Under bending conditions, the two reinforcing plates 223 each bear the bending moment component, and the lever arm formed by their parallel spacing effectively improves the bending stiffness. When a horizontal torsional load occurs, the parallel reinforcing plates 223 form a torque balance through shear action, preventing relative rotation at the connection between the mounting plate 222 and the mounting block 221.

[0068] This application further proposes to open through holes 2231 in the reinforcing plate 223.

[0069] The through hole 2231 refers to a through hole formed on the surface of the reinforcing plate 223. Specifically, it can be a circular, elliptical, or polygonal hole, and the size and distribution of the hole are designed according to the stress requirements. The function of the through hole 2231 is to reduce the amount of material used in the reinforcing plate 223 itself, while maintaining the mechanical transmission path between the mounting plate 222 and the mounting block 221, thus ensuring a balance between structural lightweighting and load-bearing performance.

[0070] Specifically, the through holes 2231 are evenly distributed in the non-stress concentration areas of the reinforcing plate 223, ensuring that the remaining portion after material removal still forms a continuous force-transfer structure. When the supporting body 22 bears a load, the plate at the edge of the through holes 2231 distributes the load to the mounting plate 222 and mounting block 221 through stress dispersion, preventing excessive local stress from causing structural failure. The through holes 2231 also allow for pipeline routing or auxiliary fixing during construction, improving the structure's adaptability in complex construction scenarios.

[0071] Through the above technical solution, this application realizes the convenient handling and rapid installation of the support component 2 during the construction process, reduces material waste and optimizes on-site operation efficiency, while ensuring the structural stability and reliability of the support body 22 under load.

[0072] This application further proposes a support bracket structure 100 including four tie rods 1 and eight bolts 3, wherein the four tie rods 1 are respectively connected to the four corners of the support component 2, and each support component 2 is provided with four bolts 3.

[0073] The four tie rods 1 refer to the four tension members that pass through the column 200 and connect the two side support components 2. They can be made of high-strength alloy steel and are symmetrically distributed at the four corners of the support components 2 to form a bidirectional tension transmission path. The eight bolts 3 refer to the fasteners used to fix the tie rods 1 to the support components 2. They can be implemented using flange bolts, with four bolts 3 configured on each side of the support components 2 to form a multi-node constraint.

[0074] Specifically, the symmetrical arrangement of four tie rods 1 at the four corners of the support assembly 2 ensures that the tension is evenly distributed along both sides of the column 200, eliminating the problem of moment concentration caused by unilateral stress. Eight bolts 3 fix the support assembly 2 to the tie rods 1 through four connection points on each side, forming a double redundancy constraint to prevent connection failure caused by vibration or load fluctuation. The rigid connection between the four corners of the support assembly 2 and the tie rods 1 forms a closed force-bearing frame, utilizing the symmetrical support surfaces on both sides of the column 200 to distribute the vertical load and avoid local stress exceeding limits.

[0075] Through the above technical solution, this application solves the problem of poor installation stability caused by insufficient connection points in the supporting bracket structure 100. By using a four-corner symmetrical tension path and a multi-point fastening design, a stable rigid connection is formed between the supporting component 2 and the column 200, while reducing the space occupied by dense support points. This solution avoids structural deformation caused by local stress concentration while ensuring load-bearing capacity, and is suitable for construction scenarios of large-span building beams, slabs, and caps.

[0076] like Figure 4 As shown, this application further proposes that two support components 2, four tie rods 1 and eight bolts 3 constitute a set of support modules 10, and the support bracket structure 100 includes two sets of support modules 10, which are arranged in parallel in the horizontal direction.

[0077] Among them, the support module 10 refers to a standardized force-bearing unit composed of two support components 2, four tie rods 1 and eight bolts 3. Specifically, it can be realized by welding or bolt connection. The module forms a bidirectional force-bearing system through symmetrical layout.

[0078] Specifically, in each support module 10, four tie rods 1 penetrate the column 200 to form a bidirectional constraint, and two support components 2 are rigidly connected to the ends of the tie rods by eight bolts 3, forming a closed force-bearing frame. When the two modules are arranged in parallel, their support planes 21 are at the same horizontal level, and the main beam 300 can span across the support planes 21 of the two modules. This layout allows the load to be synchronously transferred to the column 200 through the two modules, avoiding a single module bearing the entire bending moment. Through the above technical solution, this application effectively solves the problems of low space utilization and uneven stress distribution in traditional support systems.

[0079] like Figure 6 As shown, this application further proposes a support system for a large-span cast-in-place beam-slab structure, including several columns 200 arranged in an array, several supporting bracket structures 100 mounted on the columns 200, main beams 300 spaced apart along a first direction, and secondary beams 400 spaced apart along a second direction. The main beams 300 include two parallel main Bailey beams, located on either side of the same row of columns 200; the secondary beams 400 are vertically lapped on the main beams 300 to support the box girder formwork.

[0080] The supporting bracket structure 100 refers to the load-bearing component fixed to the column 200 by pre-embedded tie rods. It can be implemented using steel components with supporting planes 21 and mounting holes, replacing traditional dense support points and reducing the space occupied on the construction site. The main Bailey beam is a truss beam assembled from standard Bailey panels. It can be implemented by segmented splicing. Its symmetrical distribution on both sides of the column 200 can distribute the load and improve lateral stability. The secondary beam 400 refers to the auxiliary load-bearing beam arranged perpendicular to the main beam 300. It can be implemented using I-beams or composite beam structures. It transfers the load to the main beam 300 through a cross grid, forming a multi-level force transmission path.

[0081] Specifically, the arrayed columns 200 form the basic support frame, and the supporting bracket structures 100 are selectively installed on some of the columns 200 to avoid redundant support points. When the main beams 300 are arranged along the first direction, the two main Bailey beams are respectively close to both sides of the columns 200, forming a symmetrical force-bearing structure and effectively reducing unilateral bending moments. The secondary beams 400 are arranged along the second direction and intersect the main beams 300 perpendicularly, forming a spatial grid structure. The load of the box girder formwork is transferred to the main beams 300 through the secondary beams 400, and then distributed to the columns 200 through the supporting bracket structures 100. The hierarchical arrangement of the main Bailey beams and secondary beams 400 reduces the lateral space occupied while ensuring load-bearing capacity, leaving operating areas for construction equipment passage and other work processes.

[0082] Through the above technical solution, this application solves the problem of limited site space caused by the dense support points in traditional support systems, and realizes the direct installation of high-load-bearing anchor points on the column 200. The symmetrical arrangement of the main Bailey beams enhances lateral stability, the grid force transmission path of the secondary beams 400 optimizes load distribution, and the selective installation of the support bracket structure 100 reduces redundant components, providing working space for construction equipment and other processes.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
