Description

Technical Field

[0001] This invention relates to the field of building component technology, specifically to a large-span prefabricated composite beam aluminum alloy formwork reinforcement component. Background Technology

[0002] A large-span precast composite beam aluminum alloy formwork reinforcement component is a type of component used in the construction industry. In the construction process, aluminum alloy formwork needs to be installed first, which is similar to the skeleton of the building. After the aluminum alloy formwork is installed, composite slabs and composite beams need to be installed. After reinforcement, the concrete is poured. After the pouring is completed (after the shaping process of the building is finished), the aluminum alloy formwork can be removed. The reinforcement component refers to the component that connects the aluminum alloy formwork and the composite beam.

[0003] For example, publication number CN203701633U discloses a novel composite beam component. This component includes an original beam and an L-shaped beam that partially encloses the original beam. The joint surfaces of the original beam and the L-shaped beam are coated with a bonding agent such as pure cement slurry to form a concave-convex surface. The original beam has insertion holes, and reinforcing bars in these holes are connected to the L-shaped beam. The L-shaped beam is connected to the floor slab via strip-shaped holes drilled through the reinforcing bars. Open composite stirrups are provided inside the L-shaped beam. The advantages of this utility model are: it employs structural rebar anchoring technology, planting a certain number of reinforcing bars connected to the composite beam on the reinforced beam. Through this innovative design and construction method, the bonding capacity between the reinforced beam and the composite beam is guaranteed, while minimizing construction trauma to the reinforced beam. This minimally invasive construction method ensures the safety of the beam reinforcement project.

[0004] After the aluminum alloy formwork is installed, composite slabs and beams are installed. Once these components are reinforced, cement is poured. During pouring, the aluminum alloy formwork bears the weight of the composite slabs, beams, and cement. This causes the ends of the formwork to become wedged between the building and the floor after shaping. The building's pressure is directly transferred to the formwork, making subsequent dismantling difficult. Although methods using liftable components to connect the aluminum alloy formwork to the composite beams exist, the lifting mechanism... The components are driven and self-locked by a lead screw. However, the self-locking of the lead screw thread cannot withstand the pressure generated during the shaping stage of the building, resulting in displacement. Subsequently, some locking mechanisms were developed, such as inserting a metal rod into a corresponding hole to lock the lead screw. However, the gap between the holes is relatively large, which limits the locking distance of the lead screw each time. This reduces the accuracy of the lead screw lifting and lowering, making it impossible for the component with lead screw lifting and lowering to adjust the distance adaptively according to the distance between the aluminum alloy formwork and the composite beam. Although this improves the compressive strength of the component, it reduces the adjustment accuracy of the component.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing large-span precast composite beam aluminum alloy formwork reinforcement components. Summary of the Invention

[0006] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a large-span precast composite beam aluminum alloy formwork reinforcement component to solve the problem mentioned in the background that while traditional screw lifting components can address the insufficient compressive strength of screws, they also reduce the adjustment accuracy of the screw lifting components.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a large-span precast composite beam aluminum alloy formwork reinforcement component, comprising an aluminum alloy formwork, a high-precision adjustment mechanism connected to one end of the aluminum alloy formwork for connection with other building components for freely adjusting the locking distance according to the distance between the formwork and the building, an auxiliary reinforcement mechanism disposed inside the high-precision adjustment mechanism for increasing friction with the high-precision adjustment mechanism to enhance the compressive strength of the high-precision adjustment mechanism, and a composite beam connected to the top of the high-precision adjustment mechanism;

[0008] The high-precision adjustment mechanism includes a lifting structure and a lead screw disposed inside the high-precision adjustment mechanism. One end of the lifting structure and the lead screw is connected to a bevel gear set. The top of the bevel gear set is connected to a connecting rotating block. The top of the connecting rotating block is provided with an adjusting rod. One end of the adjusting rod is connected to a connecting rod. One end of the connecting rod is connected to the lifting block.

[0009] The auxiliary reinforcement mechanism includes a protrusion disposed on the inner wall of the auxiliary reinforcement mechanism, and a slider is connected to one end of the protrusion.

[0010] Preferably, the inner wall of the lifting block is movably connected to an inner rod, the outer wall of the lifting block is movably installed with an active connecting rod, the outer wall of the active connecting rod is provided with a rubber sheet, one end of the active connecting rod is connected to a driven connecting rod, and the outer wall of the connecting rod is movably installed with a pressing plate.

[0011] Preferably, one end of the inner rod is connected to an insert rod, the outer wall of the connecting rotating block is provided with multiple insert plates, and the inner wall of the connecting rotating block is provided with an internal rubber ring.

[0012] Preferably, the inner wall of the connecting block is provided with a cavity, and the bottom of the cavity of the connecting block is inclined and provided with a sliding groove.

[0013] Preferably, the internal rubber rings are all located at the inclined part of the bottom of the connecting block cavity, and the width of the internal rubber rings is slightly larger than the width of the sliding groove provided in the connecting block cavity.

[0014] Preferably, the outer wall of the multi-position insert plate is provided with an opening, and the diameter of the opening of the multi-position insert plate is adapted to the diameter of the insert rod.

[0015] Preferably, the bottom of the outer wall of the pressing plate is connected to one end of the insertion rod, and one end of the insertion rod is connected to one end of the inner rod.

[0016] Preferably, one end of the connecting rod is connected to the outer wall of the lifting block, and the other end of the connecting rod is connected to one end of the adjusting rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes a high-precision adjustment mechanism and an auxiliary reinforcement mechanism to flexibly adjust the locking distance between the aluminum alloy formwork and the composite beam according to the actual construction spacing. This solves the problem of insufficient adjustment precision caused by the large gap in traditional hole-insertion reinforcement methods. Previous locking methods could only be adjusted at fixed intervals, which easily led to the formwork and composite beam not fitting tightly when encountering non-standard distances. However, this invention, through a high-precision adjustment mechanism and an auxiliary reinforcement mechanism combined with a screw and bevel gear transmission structure, can precisely fine-tune according to the measured distance on site, ensuring a tight fit between the aluminum alloy formwork and the composite beam. This ensures the accuracy of formwork installation during the construction of large-span composite beams, avoids concrete forming quality problems caused by adjustment errors, and prevents subsequent formwork deformation due to errors. This makes the connection between the formwork and the components more in line with actual construction needs, making the entire construction process more precise and reliable.

[0019] 2. This invention simplifies construction operations while significantly enhancing the compressive strength of components through a high-precision adjustment mechanism and auxiliary reinforcement mechanism. In traditional aluminum alloy formwork dismantling, the formwork bears the pressure of the composite beams and concrete, causing both ends to be tightly pressed against the ground and building, making subsequent dismantling cumbersome. This invention, however, utilizes a high-precision adjustment mechanism and auxiliary reinforcement mechanism to enhance and eliminate pressure through the friction between the rubber pads and internal rubber, making the dismantling process easier, shortening dismantling time, and improving construction efficiency. Simultaneously, the locking force of the screw rod foundation and the friction of the auxiliary reinforcement mechanism form a dual compressive strength structure, effectively withstanding the pressure of the composite beams and concrete, preventing formwork deformation due to stress, reducing subsequent concrete repair work, ensuring construction safety, reducing construction costs, and achieving a dual improvement in operational convenience and structural stability.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 15 The present invention provides a technical solution: a large-span precast composite beam aluminum alloy formwork reinforcement component, including an aluminum alloy formwork 1, a high-precision adjustment mechanism 2 connected to one end of the aluminum alloy formwork 1 for connection with other building components and for freely adjusting the locking distance according to the distance between the formwork and the building, and an auxiliary reinforcement mechanism 3 disposed inside the high-precision adjustment mechanism 2 for increasing friction with the high-precision adjustment mechanism 2 to enhance the compressive strength of the high-precision adjustment mechanism 2, and a composite beam 4 connected to the top of the high-precision adjustment mechanism 2;

[0038] The high-precision adjustment mechanism 2 includes a lifting structure and a lead screw 201 disposed inside the high-precision adjustment mechanism 2. One end of the lifting structure and the lead screw 201 is connected to a bevel gear set 202. The top of the bevel gear set 202 is connected to a connecting rotating block 203. The top of the connecting rotating block 203 is provided with an adjusting rod 204. One end of the adjusting rod 204 is connected to a connecting rod 205. One end of the connecting rod 205 is connected to a lifting block 206.

[0039] The auxiliary reinforcement mechanism 3 includes a protrusion 303 disposed on the inner wall of the auxiliary reinforcement mechanism 3, and a slider 304 is connected to one end of the protrusion 303.

[0040] In this embodiment, when using this large-span precast composite beam aluminum alloy formwork reinforcement component, the user needs to connect the lifting structure and the bottom of the screw 201 to one end of the aluminum alloy formwork 1. The connection method only needs to use conventional methods in the art. After that, the user needs to measure the distance between the lifting structure and the top of the screw 201 and the composite beam 4. After the measurement is completed, the user can hold the adjusting rod 204 and lift it slightly upwards and press the pressing plate 211 to rotate the connecting rotating block 203. When the connecting rotating block 203 rotates, it will drive the bevel gear set 202 to rotate. When 202 rotates, it will drive the lifting structure and lead screw 201 to rotate, thereby raising and lowering the lifting structure and lead screw 201. The raising and lowering of the lifting structure and lead screw 201 will make the top of the lifting structure and lead screw 201 fit tightly against the bottom of the composite beam 4. (The user can hold the adjusting rod 204 and lift it slightly upward and press the pressing plate 211 to make the lifting structure and lead screw 201 move. This is not only simple to operate, but also eliminates the pressure between the composite beam 4 and the lifting structure and lead screw 201, thereby reducing the inconvenience caused by pressure during subsequent dismantling.)

[0041] The inner wall of the lifting block 206 is movably connected to an inner rod 207, and the outer wall of the lifting block 206 is movably installed with an active connecting rod 208. The outer wall of the active connecting rod 208 is provided with a rubber sheet 209. One end of the active connecting rod 208 is connected to a driven connecting rod 210, and the outer wall of the connecting rod 205 is movably installed with a pressing sheet 211.

[0042] In this embodiment, when the user holds the adjustment rod 204 and lifts it slightly upward and presses the pressing plate 211, in order to ensure that the lifting block 206 can move upward, the user also needs to press the pressing plate 211. Since the bottom of the pressing plate 211 is connected to the insertion rod 301 and the inner rod 207, pressing the pressing plate 211 can keep the inner rod 207 in a fixed state, so that the lifting block 206 can move along the outer wall of the inner rod 207.

[0043] One end of the inner rod 207 is connected to the insertion rod 301. The outer wall of the connecting block 203 is provided with multiple insertion plates 302, and the inner wall of the connecting block 203 is provided with an internal rubber ring 305.

[0044] In this embodiment, when the user needs to hold the adjustment rod 204 and lift it slightly upward, in order to ensure that the lifting block 206 can move upward, the user also needs to press the pressing plate 211. Since the bottom of the pressing plate 211 is connected to the insert rod 301 and the inner rod 207, pressing the pressing plate 211 can keep the inner rod 207 in a fixed state, so that the lifting block 206 can move along the outer wall of the inner rod 207.

[0045] The inner wall of the connecting block 203 is provided with a cavity, and the bottom of the cavity of the connecting block 203 is inclined and provided with a sliding groove.

[0046] In this embodiment, in the initial state, the diameter of the bottom of the cavity of the connecting block 203 is slightly larger than the diameter of the active connecting rod 208 and the driven connecting rod 210. When the user inserts the adjusting rod 204 into the connecting block 203, the insertion rod 301 at the bottom of the pressing plate 211 will be aligned with the opening of the multi-position insertion plate 302 and inserted until the insertion rod 301 is inserted to the bottom of the inner wall of the connecting block 203, which will squeeze the slider 304, causing the slider 304 to drive the protrusion 303 to slide along the groove in the cavity of the connecting block 203. When the protrusion 303 slides, it will slightly open the internal rubber ring 305, so that the internal rubber ring 305 will stick to the rubber sheet 209, thereby generating friction (by using the method that the internal rubber ring 305 sticks to the rubber sheet 209, the compressive strength of the lifting structure and the screw 201 is increased, preventing the screw from being unable to withstand the pressure of the composite beam 4 and subsequent pouring, resulting in loosening and deformation).

[0047] The internal rubber rings 305 are all located at the inclined part of the bottom of the cavity of the connecting block 203, and the width of the internal rubber rings 305 is slightly larger than the width of the groove provided in the cavity of the connecting block 203.

[0048] In this embodiment, when the insertion rod 301 is inserted to the bottom of the inner wall of the connecting block 203, it will squeeze the slider 304, causing the slider 304 to drive the protrusion 303 to slide along the groove in the cavity of the connecting block 203. When the protrusion 303 slides, it will slightly open the inner rubber ring 305, so that the inner rubber ring 305 will stick to the rubber sheet 209, thereby generating friction.

[0049] The outer wall of the multi-position insertion plate 302 is provided with openings, and the diameter of the openings of the multi-position insertion plate 302 is adapted to the diameter of the insertion rod 301.

[0050] In this embodiment, when the adjusting rod 204 is inserted into the connecting block 203, the insert rod 301 at the bottom of the pressing plate 211 will be aligned with the opening of the multi-position insert plate 302 and inserted until the insert rod 301 is inserted to the bottom of the inner wall of the connecting block 203, which will squeeze the slider 304, causing the slider 304 to drive the protrusion 303 to slide along the groove in the cavity of the connecting block 203. (The locking distance between the aluminum alloy template 1 and the composite beam 4 can be flexibly adjusted according to the actual construction spacing through the high-precision adjusting mechanism 2 and the auxiliary reinforcement mechanism 3, thereby solving the problem of insufficient adjustment accuracy caused by the large gap in the traditional hole insertion rod reinforcement method. The previous locking method can only be adjusted according to a fixed spacing. When encountering non-standard distances, the template and the composite beam 4 are not tightly fitted. However, the present invention, through the high-precision adjusting mechanism 2 and the auxiliary reinforcement mechanism 3 in conjunction with the transmission structure of the screw and bevel gear, can be precisely finely adjusted according to the actual measured distance on site, so that the aluminum alloy template 1 and the composite beam 4 are tightly fitted.)

[0051] The bottom of the outer wall of the pressing plate 211 is connected to one end of the insertion rod 301, and one end of the insertion rod 301 is connected to one end of the inner rod 207.

[0052] In this embodiment, since the bottom of the pressing plate 211 is connected to the insert rod 301 and the inner rod 207, pressing the pressing plate 211 can fix the inner rod 207, so that the lifting block 206 can move along the outer wall of the inner rod 207.

[0053] One end of the connecting rod 205 is connected to the outer wall of the lifting block 206, and the other end of the connecting rod 205 is connected to one end of the adjusting rod 204.

[0054] In this embodiment, when the adjustment rod 204 is lifted by hand, the connecting rod 205 connected to one end of the adjustment rod 204 will drive the lifting block 206 to slide upward along the outer wall of the inner rod 207. When the lifting block 206 slides upward, it will drive the active connecting rod 208 to rotate. When the active connecting rod 208 rotates, it will drive the driven connecting rod 210 to rotate. At this time, the diameter of the active connecting rod 208 and the driven connecting rod 210 will decrease due to the rotation. The rubber sheet 209 provided on the outer wall of the active connecting rod 208 will disengage from the contact between it and the inner rubber ring 305, resulting in the disappearance of friction.

[0055] Working principle: First, when using this type of large-span precast composite beam aluminum alloy formwork reinforcement component, the user needs to connect the bottom of the lifting structure and the screw rod 201 to one end of the aluminum alloy formwork 1. The connection method only needs to use conventional methods in the field. Then, the user needs to measure the distance between the top of the lifting structure and the screw rod 201 and the composite beam 4. After the measurement is completed, the user can hold the adjusting rod 204 and lift it slightly upwards and press the pressing plate 211 to rotate the connecting block 203. When the connecting block 203 rotates, it will drive the bevel gear set 202 to rotate. When the bevel gear set 202 rotates, it will drive the lifting structure and the screw rod 201 to rotate, thereby making the lifting structure and the screw rod 201 rise and fall. The rise and fall of the lifting structure and the screw rod 201 will make the top of the lifting structure and the screw rod 201 close to the bottom of the composite beam 4. Then, the user can use conventional methods in the field to fix the top of the lifting structure and the screw rod 201 to the bottom of the composite beam 4. After the fixation is completed, the subsequent reinforcement and pouring work can be carried out.

[0056] Secondly, during the pouring process and the waiting period after pouring, the aluminum alloy formwork 1 will bear a certain pressure, which will also cause the lifting structure and the lead screw 201 to bear a certain pressure. However, the threads of the lifting structure and the lead screw 201 alone cannot withstand the pressure. Previously, when the adjusting rod 204 was lowered, gravity would cause the adjusting rod 204 to reset. When the adjusting rod 204 is lifted by hand, the connecting rod 205 connected to one end of the adjusting rod 204 will drive the lifting block 206 to slide upward along the outer wall of the inner rod 207. When the lifting block 206 slides upward, it will drive the active connecting rod 208 to rotate. When the active connecting rod 208 rotates, it will drive the driven connecting rod 210 to rotate. At this time, the diameter of the active connecting rod 208 and the driven connecting rod 210 will decrease due to the rotation. The rubber on the outer wall of the active connecting rod 208... When the rubber sheet 209 disengages from the inner rubber ring 305, the friction disappears. At this time, the connecting block 203, no longer constrained by the friction between the rubber sheet 209 and the inner rubber ring 305, will be in a movable state. Conversely, when the adjusting rod 204 resets, the active connecting rod 208 and the driven connecting rod 210 will reset, causing the rubber sheet 209 and the inner rubber ring 305 to adhere tightly and generate friction to constrain the connecting block 203, thus fixing the connecting block 203 in a fixed state. In this way, the friction generated by the tight adhesion between the rubber sheet 209 and the inner rubber ring 305, combined with the constraint force of the lifting structure and the thread of the lead screw 201, will improve the pressure reduction capacity of the lifting structure and the lead screw 201, so that the lifting structure and the lead screw 201 can remain locked even when under pressure.

[0057] Finally, after the pouring is completed and the lifting structure and screw rod 201 need to be removed, simply loosen the connection between the top of the lifting structure and screw rod 201 and the composite beam 4. Then, the user can lift the adjusting rod 204 upwards, creating a gap between the rubber sheet 209 and the inner rubber ring 305. The user can then rotate the connecting block 203 to adjust the height of the lifting structure and screw rod 201. After adjustment, the pressure between the aluminum alloy template 1 and the composite beam 4 will disappear, and the aluminum alloy template 1 can then be removed. When installing the components of this invention, the user only needs to adjust the rod... Insert 204 into the cavity of the connecting block 203. Since the active link 208 and the driven link 210 are movable, when entering a slightly narrower cavity, the cavity will compress the active link 208 and the driven link 210, causing them to rotate and change their diameter. When reaching the bottom of the cavity of the connecting block 203, the inclined shape of the bottom cavity means that the space at the bottom of the cavity is slightly larger, causing the lifting block 206 to slide downward along the outer wall of the inner rod 207 due to gravity, thereby driving the active link 208 and the driven link 210 to open. As mentioned above, the active link 20... Since the driving link 208 and driven link 210 need to rotate, in order to provide a certain rotation space for the driving link 208 and driven link 210, in the initial state, the diameter of the bottom of the cavity of the connecting block 203 is slightly larger than the diameter of the driving link 208 and driven link 210. When the user inserts the adjusting rod 204 into the connecting block 203, the insert rod 301 at the bottom of the pressing plate 211 will be aligned with the opening of the multi-position insert plate 302 and inserted until the insert rod 301 is inserted to the bottom of the inner wall of the connecting block 203, which will squeeze the slider 304, causing the slider 304 to drive the protrusion 303 along the sliding plate 303 cavity. When the groove slides, the inner rubber ring 305 will be slightly opened when the protrusion 303 slides, so that the inner rubber ring 305 will stick to the rubber sheet 209, thereby generating friction. When the user needs to hold the adjustment rod 204 and lift it slightly, in order to ensure that the lifting block 206 can move upward, the user also needs to press the pressing plate 211. Since the bottom of the pressing plate 211 is connected to the insertion rod 301 and the inner rod 207, pressing the pressing plate 211 can keep the inner rod 207 in a fixed state. In this way, the lifting block 206 can move along the outer wall of the inner rod 207. Thus, the work of the present invention is completed.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
