Description

Technical Field

[0001] This invention belongs to the field of frame beam formwork technology, and particularly relates to a reinforced frame beam formwork structure that increases the cross section of the beam. Background Technology

[0002] During the use of building structures, some existing frame beams may have insufficient cross-sectional dimensions and insufficient load-bearing capacity due to changes in design load, long service life, structural damage, etc. It is necessary to enlarge the cross-section and strengthen them to improve the load-bearing capacity and structural stability of the frame beams and ensure the safe use of the building structure.

[0003] Currently, the commonly used formwork structures in the reinforcement construction of increased beam cross-sections have many defects: First, the formwork and the reinforcing steel frame have poor compatibility, and the connection method of the steel frame components is unreasonable, resulting in an unstable connection between the steel frame and the original beam, poor reinforcement effect, and easy problems such as steel frame displacement and loosening; Second, the formwork components lack effective limiting and supporting structures, and the positioning is inaccurate during installation, which can easily lead to deformation such as side plate tilting, separation, and bottom plate settlement during concrete pouring, affecting the construction accuracy of increasing the beam cross-section; Third, the construction process is cumbersome, the connection of various parts of the steel frame components and the assembly of the formwork components are inefficient, time-consuming and labor-intensive, and the integrity and stability of the reinforced structure are difficult to guarantee, which cannot effectively solve the load-bearing capacity defects caused by insufficient beam cross-section, thus posing hidden dangers to construction quality and structural safety.

[0024] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] Example 1 See Figures 1 to 4 This invention provides a reinforced frame beam formwork structure for increasing the cross-section of a beam, comprising a steel frame assembly and a formwork assembly. The steel frame assembly is fixedly connected to the underside of the original beam reinforcement and is arranged in a rectangular frame to provide installation support for the formwork assembly. The steel frame assembly includes a U-shaped hoop 1 fixed to the original beam reinforcement, a bottom reinforcement 3 connected to the U-shaped hoop 1, a tie bar 4 connecting the original beam and the bottom reinforcement 3, an end reinforcing S-shaped bar 2, and a top flat steel hoop 5 connected to the end of the bottom reinforcement 3. The formwork assembly includes side plates 6 that fit against both sides of the original beam, a bottom plate 7 that supports concrete, a feeder 10 for feeding concrete, and a vertical limiting plate 8 and a horizontal limiting plate 9 for positioning the bottom plate 7 and the side plates 6. The formwork assembly is fixed by external steel frame support, and the formwork assembly wraps around the steel frame assembly with the upper edge of the side plates fitting against the side of the original beam.

[0026] Specifically, the steel frame assembly is connected as follows: the U-shaped hoop 1 is fixedly connected to the original beam reinforcement by welding; the bottom reinforcement 3 is fixedly connected to the upper bottom of the U-shaped hoop 1; the upper end of the tie bar 4 is fixedly connected to the lower end of the original beam, and the lower end of the tie bar 4 is fixedly connected to the bottom reinforcement 3; the top flat steel hoop 5 is fixedly sleeved on the support column of the original beam, and the end of the bottom reinforcement 3 is welded to the top flat steel hoop 5; one end of the end reinforcing S-shaped reinforcement 2 is welded to the original beam reinforcement, and the other end is fixedly connected to the bottom reinforcement 3, with the middle part in an inclined state.

[0027] Specifically, in the template assembly, two side plates 6 are provided, and the two side plates 6 are respectively attached to the two sides of the original beam. The feeding part 10 is opened on the side plate 6. The bottom plate 7 is set between the two side plates 6 and is used to receive the poured concrete. The horizontal limiting plate 9 is located on the lower side of the bottom plate 7. The upper surface of the horizontal limiting plate 9 is attached to the lower surface of the bottom plate 7. The two sides of the horizontal limiting plate 9 are attached to the inner wall of the side plate 6, and the lower surface of the horizontal limiting plate 9 is flush with the lower surface of the side plate 6. The lower side of the horizontal limiting plate 9 is supported by a steel frame.

[0028] Specifically, the vertical limiting plate 8 is attached to the outer side of the side plate 6, and the lower surface of the vertical limiting plate 8 is flush with the lower surface of the side plate 6; a bolt 11 is fixedly connected to the lower side of the bottom plate 7, a support frame 12 is sleeved on the bolt 11, and a nut 13 is provided on the bolt 11, the upper side of the nut 13 is pressed tightly against the lower side of the support frame 12; the support frame 12 is provided with two arc-shaped support grooves 14, and a support rod 15 is provided in the arc-shaped support grooves 14. The support rod 15 is attached to the lower surface of the side plate 6, the vertical limiting plate 8 and the horizontal limiting plate 9, and is used to support and align the side plate 6, the vertical limiting plate 8 and the horizontal limiting plate 9.

[0029] Specifically, a flexible connector 16 is connected to the outer side of one of the vertical limiting plates 8, and an insertion hole 17 is provided on the flexible connector 16; an L-shaped rod 18 is fixedly connected to the outer side of the other vertical limiting plate 8, one end of the L-shaped rod 18 is inserted into the insertion hole 17, and the L-shaped rod 18 is in contact with the lower surface of the side plate 6, the vertical limiting plate 8 and the horizontal limiting plate 9, so as to limit the two vertical limiting plates 8 and the side plate 6 and prevent the two side plates 6 from moving away from each other.

[0030] This reinforced frame beam formwork structure with enlarged cross-section achieves foundation reinforcement through a strong connection between the steel frame components and the original beam. Precise casting is achieved through the coordination of the formwork components and the steel frame components, ultimately increasing and reinforcing the original cross-section of the beam. The specific working principle is as follows: 1. Pre-construction preparation: First, break and clean the lower surface of the existing beam to expose the original beam reinforcement, providing a connection foundation for the installation of the steel frame components, ensuring that the steel frame components can be effectively connected to the original beam, and guaranteeing the reinforcement effect.

[0031] 2. Steel Frame Assembly Installation and Fixing: According to the design position, the U-shaped hoop 1 is welded and fixed to the original beam reinforcement, serving as the core support structure of the steel frame assembly. Then, the bottom reinforcement 3 is fixedly connected to the U-shaped hoop 1 with tie wire. Simultaneously, the end of the bottom reinforcement 3 is welded to the top flat steel hoop 5, which is fixedly sleeved onto the original beam support column, achieving bidirectional fixation of the bottom reinforcement 3. Next, the end-reinforcing S-shaped reinforcement 2 is welded, with one end welded to the original beam reinforcement and the other end fixedly connected to the bottom reinforcement 3. It is arranged at an angle in the middle to enhance the structural strength of the steel frame assembly's ends and prevent stress concentration at the ends. Finally, the tie rod 4 is installed, with its upper end fixedly connected to the lower end of the original beam and its lower end fixedly connected to the bottom reinforcement 3, further connecting the steel frame assembly to the original beam. This ensures that the steel frame assembly forms a stable rectangular reinforced frame, providing reliable support for the subsequent installation of the formwork assembly.

[0032] 3. Template Component Installation and Positioning: Based on the support of the steel frame components, install the horizontal limiting plate 9 and support it with the steel frame. Then, lay the base plate 7 on the horizontal limiting plate 9, using the horizontal limiting plate 9 to support and position the base plate 7. Next, install two side plates 6 on both sides of the original beam, ensuring that the side plates 6 are flush with the sides and lower surfaces of the horizontal limiting plate 9. Then, install the vertical limiting plate 8 on the outside of the side plates 6, ensuring that the lower surface of the vertical limiting plate 8 is flush with the lower surface of the side plates 6. Finally, install the base plate 7... The support frame 12, connected by side bolts 11, adjusts the position of the support rods 15 so that they fit against the lower surfaces of the side plate 6, vertical limiting plate 8, and horizontal limiting plate 9 respectively, providing support and alignment to prevent sinking or displacement. Finally, using the cooperation of the flexible connector 16 and the L-shaped rod 18, one end of the L-shaped rod 18 is inserted into the insertion hole 17 of the flexible connector 16 to limit the two vertical limiting plates 8 and the side plate 6, preventing the side plate 6 from being pushed away by lateral pressure during concrete pouring. It should be noted that the purpose of the flexible connector 16 is for initial positioning; the side plate 6, vertical limiting plate 8, and bottom plate 7 can be connected later using screws.

[0033] 4. Pouring and Shaping: Concrete is injected into the pouring space enclosed by the template assembly through the feeding device 10 on the side plate 6. During the pouring process, the steel frame assembly continuously provides stable support for the template assembly. Under the action of the limiting and supporting structure, the template assembly maintains accurate positioning and structural stability, avoiding deformation. After the concrete is poured and cured, the template assembly is removed. The steel frame assembly and the newly poured concrete form an integral whole, jointly increasing the cross section of the beam, improving the load-bearing capacity and structural stability of the beam, and completing the reinforcement of the beam.

[0034] Furthermore, the supporting rod 15 is a round rod, and the two supporting rods 15 are arranged in parallel, with the distance between the opposite sides of the two supporting rods 15 being equal to the distance between the two horizontal limiting plates 9. The supporting frame 12 and the supporting rod 15 have two working positions. When in the first working position, the supporting rod 15 is in contact with the lower surfaces of the side plate 6, the vertical limiting plate 8, and the horizontal limiting plate 9, for supporting and aligning the side plate 6, the vertical limiting plate 8, and the horizontal limiting plate 9, i.e. Figure 1 The position of the support rod 15 is as follows: When it is in the second position, the support rod 15 and the horizontal limiting plate 9 are parallel; and both support rods 15 are located between the two horizontal limiting plates 9, and the horizontal limiting plates 9 and the support rods 15 are in contact; and at this time, the end of the support frame 12 is in contact with the lower edge of the horizontal limiting plate 9.

[0035] During the template assembly installation and positioning stage, after the support frame 12 is raised to the preset height using bolts 11 and nuts 13, two round rod-shaped support rods 15 are placed in the two arc-shaped support grooves 14 of the support frame 12, ensuring that the two support rods 15 are arranged in parallel. At this time, the distance between the two support rods 15 on the opposite side is equal to the distance between the two horizontal limiting plates 9. This arrangement allows the support rods 15 to position the two horizontal limiting plates 9, making the two horizontal limiting plates 9 parallel to each other and more accurately positioned. Furthermore, the end of the support frame 12 is in contact with the lower edge of the horizontal limiting plates 9, thus ensuring that the heights of the two horizontal limiting plates 9 are initially consistent. With the two horizontal limiting plates 9 accurately positioned, the side plates 6 on both sides are also more accurately positioned because they are in contact with the horizontal limiting plates 9.

[0036] It should be noted that in the second station, the position of the support rod 15 is higher than in the first station. The height of the support frame 12 can be adjusted by rotating the nut 13. The second station is a station in the installation process, while the first station is the final station. This setting allows for more precise positioning of the two horizontal limiting plates 9, ensuring they are parallel and at the same height, with the outer edges of the two horizontal limiting plates 9 flush with the edge of the base plate 7. Based on this, when installing the side plate 6, the upper part of the inner wall of the side plate 6 can fit against the original beam, while the lower part fits against both the outer edge of the horizontal limiting plate 9 and the edge of the base plate 7, thus achieving more precise side wall positioning.

[0037] The first (final) station is when the two horizontal limiting plates 9 are accurately positioned and installed. Then, rotate the nut 13 to lower the support frame 12, which will drive the support rod 15 down to the first station. At this time, the support rod 15 is in close contact with the lower surfaces of the side plate 6, the vertical limiting plate 8 and the horizontal limiting plate 9, which will play the final supporting and alignment role, prevent the above components from sinking or shifting when pouring concrete, and ensure the overall stability of the formwork assembly.

[0038] Specifically, the feeding component 10 includes a bottom feeding plate 101, a side baffle 102, and a feeding port 103; the feeding port 103 is located on the side plate 6, the bottom of the bottom feeding plate 101 is fixedly connected to the side plate 6 and located below the feeding port 103, and the side baffle 102 is fixedly connected to the side of the bottom feeding plate 101.

[0039] Its core purpose is to solve the problems of inconvenient material feeding and concrete leakage during concrete pouring. During the concrete pouring stage, the construction workers inject concrete into the pouring space enclosed by the formwork assembly through the feed port 103. The bottom feed plate 101 can receive and guide the falling concrete, preventing the concrete from directly impacting the inner wall of the formwork and causing damage to the formwork. At the same time, it prevents concrete from leaking out from the connection between the bottom of the feed port 103 and the side plate 6. The side baffle 102 can prevent concrete from overflowing from both sides of the bottom feed plate 101, ensuring that the concrete can be injected into the pouring space accurately and efficiently, reducing construction waste, and ensuring the standardization and convenience of the pouring process.

[0040] Example 2 Based on Example 1, the following settings are made: See Figure 1-10 It also includes a limiting plate 19, which is attached to the vertical limiting plate 8. The limiting plate 19 has several locking interfaces 20 on both sides. The end of the bearing rod 15 extends to the outside of the vertical limiting plate 8 and is locked in the locking interface 20. The bottom feed plate 101 is provided with an insertion port 21. An insertion plate 22 is fixedly connected to the lower side of the limiting plate 19. The vertical limiting plate 8 is provided with a clearance groove 24. The insertion plate 22 is inserted into the clearance groove 24 and the insertion port 21.

[0041] This setup allows for several advantages. First, the bearing rod 15 can be positioned using the locking interface 20 to prevent tilting. Second, the bearing rod 15 can also be reversed to position the limiting plate 19 vertically, thus limiting the vertical limiting plate 8 and preventing it from tilting. After concrete is injected, this helps to counteract the pressure of the concrete on the side plate 6 from the inside. Third, after the concrete is filled, the bearing rod 15 can be rotated to disengage from the locking interface 20, and then the limiting plate 19 can be moved upwards to block the feed inlet 103 with the insert plate 22. Then, the bearing rod 15 can be rotated back into the locking interface 20 to continue limiting the limiting plate 19. This creates a sealed structure, preventing irregularities in the concrete at the feed inlet 103.

[0042] Furthermore, an auxiliary plate 23 is included, which is disposed in the feed inlet 103. The outer surface of the auxiliary plate 23 is attached to the insert plate 22, and the inner surface of the auxiliary plate 23 is aligned with the inner surface of the side plate 6. When the insert plate 22 is inserted into the slot 21 to block the feed inlet 103, the auxiliary plate 23 and the inner surface of the side plate 6 form a flush integral structure, effectively preventing protrusions at the feed inlet 103 after sealing, ensuring the flatness of the beam cross section after pouring, and simultaneously ensuring a tight connection between the newly poured concrete and the original beam side, enhancing the overall structural integrity.

[0043] Working principle of the invention: Preliminary preparation: Clean the underside of the original beam to expose the original beam reinforcement, providing a connection foundation for the installation of the steel frame components.

[0044] Steel frame component installation: Weld U-shaped hoop 1 to the original beam reinforcement, fix the bottom reinforcement 3 and weld it to the top flat steel hoop 5, install the end reinforcing S-shaped reinforcement 2 and tie rod 4 to form a stable rectangular reinforced frame, providing support for formwork installation.

[0045] Template component installation and positioning: First, install and support the horizontal limiting plate 9, then lay the base plate 7; next, install the side plate 6 and the vertical limiting plate 8, and align the three by supporting the load-bearing frame 12 and the load-bearing rod 15. Use the flexible connector 16 and the L-shaped rod 18 to limit the side plate 6 and prevent it from shifting during pouring. In Example 2, the limiting plate 19 and the insert plate 22 can be used to further reinforce the limiting.

[0046] Pouring and forming: Concrete is injected into the template through the feeding device 10, and the steel frame and template components ensure the stability of the pouring process; after the concrete has cured and formed, the template components are removed, and the steel frame components and the new concrete form an integral whole, completing the reinforcement of the beam.

[0047] The bearing rod 15 can switch positions by adjusting the bolts 11 and nuts 13 on the bearing frame 12, and assist the horizontal limit plate 9 in precise positioning; the feeding component 10 (including the bottom feeding plate 101, the side baffle 102, and the feeding port 103) can prevent concrete leakage, guide the feeding, and improve the standardization of pouring.
