Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a bridge load-bearing formwork structure. Background Technology

[0002] Bridge construction is the process of transforming a bridge from a plan into a physical structure according to design requirements. It encompasses foundation construction, pier and abutment construction, superstructure installation, and ancillary facilities. It requires the comprehensive application of civil engineering, materials science, and mechanical technology, and the main body of the bridge is formed by pouring concrete, erecting steel beams, or assembling precast components.

[0003] As the scale of bridge construction in mountainous areas expands, scaffolding is required for pier construction to bear the load. The formwork and support are welded together, which poses safety hazards, leads to complex structures and insufficient stability, and is inconvenient to assemble and disassemble, resulting in low efficiency and limited applicability. Current construction methods mostly use clamps and climbing formwork, which mainly rely on friction for load bearing, resulting in high safety risks and severe wear and tear on components. Long-term repeated use leads to a certain degree of decline in various indicators of load-bearing components, which cannot meet the original design requirements and cause greater safety risks.

[0004] To address these issues, we provide a bridge load-bearing formwork structure. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge load-bearing formwork structure. By combining the quick-assembly and disassembly of the load-bearing formwork components and the leveling components, it solves the problems in the prior art where bridge construction requires the erection of scaffolding for load-bearing, the formwork and the support are welded together, which poses safety hazards, leads to complex structure, insufficient stability, inconvenient assembly and disassembly, and limited scope of application.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a bridge load-bearing formwork structure, comprising a cap beam, a quick-assembly load-bearing formwork assembly, and a leveling assembly. Columns are fixedly connected to both sides of the bottom of the cap beam, and a tie beam is fixedly connected between the two columns. The quick-assembly load-bearing formwork assembly includes two pre-embedded load-bearing members, which are pre-embedded inside the columns and located below the cap beam and tie beam, respectively. Load-bearing crossbeams are fixedly connected to both sides of the top of each pre-embedded load-bearing member via U-shaped clamps. Load-bearing panels are provided on the front and rear sides of the top of the load-bearing crossbeams, and locking mechanisms are installed on both sides of the top between the two load-bearing panels. The leveling assembly includes two fixing clamps installed on the surface of the columns, and a support arm is fixedly connected between the two fixing clamps. Support adjustment mechanisms are movably connected to both sides of opposite sides of the two support arms, and the top of the support adjustment mechanism is movably connected to the load-bearing panel.

[0008] The present invention is further configured such that the locking mechanism includes two fixed shells, the bottom of which is fitted to the load-bearing panel. Bolts are provided on opposite sides of the two fixed shells, and push plates are movably connected through the fixed shells on opposite sides of the two bolts. Pressure blocks are fixedly connected to the front and rear sides of opposite sides of the two push plates. A trapezoidal block is provided on the side of the pressure block away from the push plate. The bottom of the trapezoidal block is fixedly connected to the load-bearing panel. The fixed shells are used to fit over the surfaces of the two trapezoidal blocks. The bolts are used to control the movement of the push plates and pressure blocks. The pressure blocks can squeeze the slope of the trapezoidal blocks, so that the two trapezoidal blocks and the load-bearing panel are tightly fitted, thereby positioning the two load-bearing panels before installation.

[0009] The present invention is further configured such that a sliding rod is fixedly connected to both the front and rear sides of the inner cavity of the fixed shell, and a sliding sleeve is slidably connected to the surface of the sliding rod. The side of the sliding sleeve away from the cover beam extends through to the side of the push plate. The sliding rod and the sliding sleeve can limit the push plate so that it can move smoothly left and right.

[0010] The present invention is further configured such that mounting blocks are fixedly connected to both sides of the front and rear sides of the fixed shell, the top of the mounting blocks is provided with mounting holes, and the top of the load-bearing panels is provided with fixing slots. The mounting blocks and mounting holes can cooperate with the fixing slots to connect the two load-bearing panels together.

[0011] The present invention is further configured such that the support adjustment mechanism includes two support columns, the opposite sides of which are movably connected to the load-bearing panel and the support arm, respectively, and a threaded column is threaded between the two support columns. A knob is fixedly connected to the surface of the threaded column, and the support column has a thread inside that cooperates with the threaded column. The threaded column and the thread cooperate to control the movement of the two support columns. The knob allows the operator to rotate the threaded column to adjust the angle of the load-bearing panel and keep it in a horizontal state.

[0012] The present invention is further configured such that the surface of the knob is provided with anti-slip texture, and the opposite sides of the two support columns are movably connected to the load-bearing panel and the support arm through a pivot. The anti-slip texture can increase the anti-slip effect of the knob, and the pivot facilitates the change of the use angle of the support columns.

[0013] The present invention is further provided that a support block is fixedly connected to the bottom of the load-bearing panel and the top of the load-bearing beam, and mounting screw holes are provided on both sides of the top of the load-bearing panel and the top of the load-bearing beam. The support block is used to improve the stability of the load-bearing panel after installation, and the mounting screw holes enable the load-bearing panel to be connected to the load-bearing beam.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model enables the rapid assembly and disassembly of load-bearing formwork components. Pre-embedded load-bearing members are pre-installed inside the columns to provide the main load-bearing support, avoiding traditional scaffolding erection and welding. This significantly reduces the risks of working at heights and simplifies the overall structure. The load-bearing beam is securely installed on top of the pre-embedded load-bearing members via U-shaped hoops, forming a stable load-bearing platform. The load-bearing panel is placed on top to provide a working surface. The locking mechanism is connected to the trapezoidal block via a fixed shell. Rotating bolts drives the push plate and pressure block to move. The pressure block tightly presses against the inclined surface of the trapezoidal block, achieving rapid and accurate positioning and secure connection of the two load-bearing panels. This greatly improves assembly and disassembly efficiency, reduces operational difficulty, and enhances the overall stability of the formwork, effectively solving the problems of complex structure, inconvenient assembly and disassembly, and insufficient stability in existing technologies.

[0016] 2. This utility model uses a leveling component to install the support arm onto the surface of the column using a fixing clamp, providing a stable support point. The support arm is connected to the fixing clamp to transmit the supporting force. The support adjustment mechanism is movably connected to the support arm and the load-bearing panel at both ends of the support column. Rotating the knob drives the threaded column to rotate, precisely controlling the relative extension and retraction length of the two support columns, thereby smoothly adjusting the height of the corresponding corners of the load-bearing panel. This ensures that the load-bearing panel remains level throughout the construction process, improving the safety and reliability of long-term use, adapting to the levelness requirements of different construction environments, and expanding the scope of application.

The locking mechanism 44 is used for quick positioning of the two load-bearing panels 43, which facilitates their installation and fixing. The fixing clamp 51 can be installed and fixed with the support adjustment mechanism 53. The support adjustment mechanism 53 cooperates with the support arm 52 to adjust the load-bearing panel 43 horizontally, so that the load-bearing panel 43 remains in a horizontal state.

Fixing slots are provided on the top of the load-bearing panel 43. The support adjustment mechanism 53 includes two support columns 531. The opposite sides of the two support columns 531 are movably connected to the load-bearing panel 43 and the support arm 52, respectively. A threaded column 532 is threaded between the two support columns 531. A knob 533 is fixedly connected to the surface of the threaded column 532. The surface of the knob 533 is provided with anti-slip texture. The opposite sides of the two support columns 531 are movably connected to the load-bearing panel 43 and the support arm 52 through a pivot. A support block 6 is fixedly connected to the bottom of the load-bearing panel 43 and the top of the load-bearing beam 42. Mounting screw holes are provided on both sides of the top of the load-bearing panel 43 and the top of the load-bearing beam 42.

[0030] Specifically: the fixing shell 441 is used to fit over the surfaces of the two trapezoidal blocks 445; the bolt 442 is used to control the movement of the push plate 443 and the pressure block 444; the pressure block 444 can press the slope of the trapezoidal blocks 445, making the two trapezoidal blocks 445 and the load-bearing panels 43 fit tightly together, thereby positioning the two load-bearing panels 43 before installation; the sliding rod and sliding sleeve can limit the push plate 443, allowing it to move smoothly left and right; the mounting block and mounting hole can cooperate with the fixing slot to connect the two load-bearing panels 43 together; and the support column 531... The interior is threaded to cooperate with the threaded post 532. The threaded post 532 and the threaded post control the movement of the two support posts 531. The knob 533 allows the operator to rotate the threaded post 532 to adjust the angle of the load-bearing panel 43 and keep it horizontal. The anti-slip texture increases the anti-slip effect of the knob 533. The pivot allows the use angle of the support post 531 to be changed. The support block 6 is used to improve the stability of the load-bearing panel 43 after installation. The mounting screw hole allows the load-bearing panel 43 to be connected to the load-bearing beam 42.

[0031] The working principle of this utility model is as follows: Before construction, during the concrete pouring process of column 2, the pre-embedded load-bearing members 41 are first pre-embedded and fixed in the designated positions inside column 2, located below the cap beam 1 and tie beam 3. After column 2 reaches its strength, the load-bearing formwork is assembled, and the load-bearing crossbeam 42 is tightly fixed to the top two sides of the pre-embedded load-bearing members 41 with U-shaped hoops to form the main load-bearing frame. Then, two load-bearing panels 43 are placed in the front and rear areas of the top of the load-bearing crossbeam 42, respectively. After preliminary positioning, the load-bearing surface is... Locking mechanisms 44 are installed on both sides of the top of the joint of panel 43. The fixing shell 441 is fitted onto the outside of the trapezoidal blocks 445 that are respectively fixed on the two load-bearing panels 43. Then, the bolts 442 are tightened. The bolts 442 push the internal push plate 443 and pressure block 444 to move. The inclined surface of the pressure block 444 strongly presses against the corresponding inclined surface of the trapezoidal block 445, generating a wedging force. This forces the two load-bearing panels 43 and the trapezoidal blocks 445 on them to come close together and lock in place. Then, the mounting block can be connected to the load-bearing panel 43 through the mounting hole. The top fixing slots further reinforce the connection, completing the installation and fixing of the load-bearing panel 43. Disassembly only requires reversing the above steps, making the entire installation and disassembly process quick and convenient, reducing construction difficulty. Then, the leveling component 5 is installed, and the fixing clamps 51 are wrapped around and tightened to the surface of the column 2 at a suitable height. The two fixing clamps 51 are fixedly connected by the support arm 52. Between the outside of the support arm 52 and the bottom of the load-bearing panel 43, the support adjustment mechanism 53 is installed. This mechanism consists of two support columns 531 connected by threaded threaded columns 532. The two ends of the support columns 531 are respectively movably connected to the support arm 52 and the load-bearing panel 43 through the rotating shaft. By rotating the knob 533, the threaded column 532 is rotated, causing the two support columns 531 to extend or shorten relative to each other, thereby raising or lowering the corresponding corners of the load-bearing panel 43, realizing the independent adjustment of the overall level of the load-bearing panel 43, ensuring that it is in a horizontal state, and providing a stable and horizontal working and load-bearing platform for the subsequent construction of the cap beam 1, tie beam 3 and other structures.
