Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated formwork, and in particular to an assembled T-beam formwork structure. Background Art

[0002] A T-beam is a beam with a T-shaped cross-section, with the projecting sections on either side called flanges and the center section called the rib (or web). Because it's formed by removing the concrete in the tensile zone of a rectangular beam, which doesn't contribute to bending strength, it maintains the same bending strength as the original rectangular beam, while conserving concrete, reducing the member's deadweight, and improving span capacity. Currently, T-beams are a commonly used beam type in bridge construction, and their formwork is crucial. Traditional T-beam formwork is mostly monolithic, presenting certain challenges during construction: Due to the setting strength of cement, the formwork is typically removed by direct external pulling. This requires excessive force, resulting in energy waste and easily causing extensive damage to the T-beam's outer wall, reducing surface flatness and causing quality issues.

[0003] In order to solve the above problems, after searching, the invention patent with authorization announcement number CN118404681B discloses a T-beam steel formwork and its use method, including a base; a fixed block is fixedly connected to the middle of the base; two groups of first sliding grooves are symmetrically arranged on the top surface of the base about the fixed block; an inverted Z-shaped formwork is slidably connected in the first sliding groove, and the vertical plate at the bottom end of the inverted Z-shaped formwork is inverted convex; two groups of fixed plates symmetrically distributed about the fixed block are fixedly connected to the base, and a hydraulic cylinder is hinged on the fixed plate; a hydraulic rod is provided at the output end of the hydraulic cylinder; a first cavity is opened in the hydraulic rod; a sliding plate is slidably connected in the first cavity, and the first cavity is square; the side wall of the sliding plate is rotatably connected to a force-bearing rod, and the end of the force-bearing rod extends out of the hydraulic rod and is detachably hinged to the side wall of the inverted Z-shaped formwork; a reinforcing block is fixedly connected at the turning point of the inverted Z-shaped formwork, and a vibration member is provided in the reinforcing block; to solve the problem that the T-beam is easily damaged when demoulding.

[0004] Combined with the existing technology, it is found that although the existing T-beam formwork has solved the problem of easy damage to the T-beam to a certain extent, during the demoulding process using vibration, the vibration will generate a lot of noise, which will pollute the construction environment and easily cause noise nuisance to the public. It will also affect the working environment of the construction workers. In addition, high-frequency vibration may have a certain impact on the interior of the concrete structure, causing fine cracks in the concrete, reducing the density and strength of the concrete. This is especially true for the production of T-beams with high structural quality requirements. The impact is more obvious. Therefore, it is urgent to propose an assembled T-beam formwork structure to improve the above problems. Summary of the Invention

[0005] In view of the above-mentioned existing technologies, the technical problem to be solved by the present invention is that the existing technologies use vibration for demoulding, which will generate large noise due to vibration, polluting the construction environment and easily causing noise nuisance to the public. At the same time, high-frequency vibration may have a certain impact on the interior of the concrete structure, causing fine cracks in the concrete and reducing the density and strength of the concrete.

[0011] The present invention is further configured such that the inflation assembly includes a metal bellows fixedly installed in the middle of the bottom of the airbag, and a hose is fixedly installed at one end of the metal bellows, and through holes for the metal bellows and the hose to pass through are opened in the middle of the bottom of the movable frame and the middle of the bottom of the web frame, an air pump is fixedly installed on the bottom inner wall of the L-shaped side panel, and a control valve is installed at the exhaust end of the air pump, an exhaust pipe is fixedly installed at the exhaust end of the control valve, and a plurality of air distribution pipes are fixed on one side of the exhaust pipe, and one end of the air distribution pipe is fixedly connected to one end of the hose.

[0012] The present invention is further configured such that the support assembly includes grooves provided on the inner walls on both sides of the web frame, and support plates are slidably provided on the inner walls of the grooves, and first springs distributed equidistantly are fixedly installed on one side of the support plate and the inner wall of one side of the groove, and push-pull plates are hingedly connected to the other sides of the two support plates on both sides of the lifting frame.

[0013] The present invention is further configured such that the top corners of the support plate are rotatably connected to sliding rollers distributed at equal distances, and the stripping plate is attached to the sliding rollers.

[0015] The present invention is further configured such that a plurality of slots are provided on the tops of the two L-shaped side panels, and pull rods are inserted into two horizontal slots, and both ends of the pull rods are screwed with high-strength reinforcement nuts.

[0016] The present invention is further configured such that the side form support frame and the web formwork are both Z-shaped, and the side formwork support frame is attached to the outside of the web formwork, the two web formworks are attached to both sides of the bottom formwork, and a reinforcement component for reinforcing the side formwork support frame is provided on the L-shaped side panel.

[0017] The present invention is further configured such that the reinforcement assembly includes a second hydraulic cylinder fixedly mounted on the L-shaped side plate, and the piston end of the second hydraulic cylinder is fixedly mounted with the same door-shaped reinforcement rib, which is attached to the top of one side of the side mold support frame.

[0018] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0019] 1. The web formwork is composed of multiple hinged web frames. The web formwork at the inner corners is connected by a connector, while the outer corners are connected by a rotating member. The other adjacent web frames are also hinged. This hinged design enables the web formwork to better adapt to the complex corners and curves of the T-beam. It can fit tightly during the splicing process, effectively avoiding the problem of slurry leakage caused by loose formwork splicing, ensuring the forming quality of the T-beam. At the same time, the hinged structure facilitates the disassembly and turnover of the formwork, further improving the utilization rate of the formwork.

[0020] 2. The pneumatic demoulding components include a fixed plate, an airbag, a lifting frame, an air-blowing component, etc. When working, the air pump injects gas into the airbag. After the airbag expands, it pushes the lifting frame downward to squeeze the movable frame, driving the demoulding plate to descend smoothly to complete the demoulding. Compared with traditional vibration demoulding, this pneumatic demoulding method has obvious advantages. On the one hand, it can provide uniform and stable demoulding force, the action is gentle and smooth, and no high-decibel noise is generated, which effectively reduces the pollution of the surrounding environment caused by construction and avoids noise nuisance and disputes; on the other hand, it avoids the problem of fine cracks in the concrete caused by vibration and protects the T-beam in all directions. In addition, the second spring installed on the inner wall of the movable frame and the bottom of the web frame can quickly reset the demoulding plate after demoulding is completed, preparing for the next use, greatly improving the demoulding efficiency and simplifying the operation process.

[0021] 3. Through the first hydraulic cylinder, when the first hydraulic cylinder drives the side form support frame to adjust the angle, the web formwork hingedly connected to the side form support frame will be separated from the T-beam surface from top to bottom, piece by piece and in an orderly manner. Compared with the traditional demoulding method, which may cause large-scale instantaneous detachment of the formwork, this piece-by-piece separation mode greatly reduces the pulling and impact force on the T-beam surface, and avoids serious damage such as scratches, missing edges and corners caused by stress concentration on the T-beam surface at the moment of demoulding. It further improves the appearance quality and structural integrity of the T-beam finished product, reduces the later repair process, and saves time and material costs.

[0022] 4. By installing the support plate and the first spring in the support assembly in the groove of the web frame, the support assembly provides reliable support for the stripper plate during the concrete pouring process, effectively preventing the stripper plate from deforming or moving downward due to concrete pressure, and ensuring the smooth progress of the pouring work. When the airbag expands to start the demoulding process, the lifting frame will pre-drive the support plate back into the groove through the push-pull plate to make room for the stripper plate to rise and fall, avoiding mutual interference between the two. In addition, the sliding roller surface on the top of the support plate is covered with a wear-resistant rubber layer. This detailed design not only significantly reduces the friction between the stripper plate and the support plate, making the stripper plate move smoother and smoother, but also effectively buffers the contact pressure, comprehensively protecting the stripper plate surface, extending its service life, and reducing maintenance costs.

[0023] 5. By opening slots on the tops of the two L-shaped side panels, connecting them with tie rods and high-strength reinforcement nuts, and setting anti-loosening washers, this connection method can effectively enhance the connection strength between the L-shaped side panels on both sides, preventing the formwork from being deformed or displaced due to lateral pressure during concrete pouring, and ensuring the dimensional accuracy and structural stability of the T-beam. The reinforcement assembly composed of a second hydraulic cylinder and a door-shaped reinforcement rib can adjust the horizontal position of the door-shaped reinforcement rib under the action of the second hydraulic cylinder, and can carry out targeted reinforcement of the side formwork support frame, effectively resisting the lateral pressure of concrete, ensuring the overall stability of the formwork structure, and ensuring the pouring quality of the T-beam.

[0024] 6. By setting up slide rails on the hardened ground, the side formwork units are slid onto the slide rails through the base, and adjacent side formwork units are fixedly connected with bolts. This design makes the installation, disassembly and movement of the side formwork units extremely convenient, with assembly convenience and flexibility. The template structure layout can be quickly adjusted under different construction sites or T-beam size requirements. For example, when the T-beam length needs to be changed, the number of side formwork units can be easily increased or decreased without large-scale modification of the overall structure, which significantly improves construction efficiency and reduces construction difficulty and labor costs.

[0041] Please refer to Figures 1-10 The present invention provides an assembled T-beam formwork structure, comprising a hardened ground 1, a bottom formwork 3 is arranged on the hardened ground 1, and a plurality of slide rails 2 installed on the hardened ground 1 are symmetrically arranged on both sides of the bottom formwork 3, the slide rails 2 are arranged parallel to the length direction of the T-beam, and a plurality of side formwork units 4 slidably arranged on the slide rails 2 are symmetrically arranged on both sides of the bottom formwork 3, and two adjacent side formwork units 4 are fixedly connected by bolts;

[0042] Each side formwork unit 4 includes a base 5 slidably mounted on a slide rail 2, and an L-shaped side plate 6 is fixedly mounted on the top of each base 5. Two mounting seats 15 are fixed to one side of the top of the L-shaped side plate 6, and the two mounting seats 15 are rotatably connected to the side formwork support frame 8 and the web formwork 12 respectively. The two ends of one side of the side formwork support frame 8 are hinged to the two ends of one side of the L-shaped side plate 6 by a first hydraulic cylinder 7;

[0043] The web formwork 12 is composed of a plurality of hinged web frames 1201, and the inner walls of the web frame 1201 are fitted with a stripping plate 1203, and the top surface of the stripping plate 1203 is flush with the top surface of the web frame 1201. The bottom of the stripping plate 1203 is fixed with a movable frame 1213 inserted into the web frame 1201. The side mold unit 4 is provided with a pneumatic stripping assembly for adjusting the height of the movable frame 1213 and the stripping plate 1203. The pneumatic stripping assembly includes a fixed plate 1209 fixed between the inner walls of the two ends of the web frame 1201, and the bottom of the fixed plate 1209 is fixedly installed with an air bag 1210, and the bottom of the air bag 1210 is fixedly installed. There is a lifting frame 1211 for squeezing the movable frame 1213 for height adjustment. The top surface of the lifting frame 1211 is attached to the bottom surface of the fixed plate 1209. The bottom of the movable frame 1213 and the bottom inner wall of the web frame 1201 are installed with second springs 1215 distributed at equal distances. Guide grooves are provided at both ends of the outer walls of both sides of the fixed plate 1209, and guide rails 1212 inserted into the guide grooves are fixed at both ends of the inner walls of both sides of the movable frame 1213. The bottom of the airbag 1210 is provided with the same inflation assembly 13, which includes a metal bellows 1214 fixedly installed in the middle of the bottom of the airbag 1210, and the metal bellows 1214 is fixedly installed in the middle of the bottom of the airbag 1210. 1303 is fixedly installed at one end of each of the two ends of the air pump 1301. A through hole 1216 is provided at the bottom middle of the movable frame 1213 and the bottom middle of the web frame 1201 for the metal bellows 1214 and the hose 1303 to pass through. An air pump 1301 is fixedly installed on the bottom inner wall of the L-shaped side plate 6, and a control valve is installed at the exhaust end of the air pump 1301. An exhaust pipe 1302 is fixedly installed at the exhaust end of the control valve. A plurality of air distribution pipes are fixed on one side of the exhaust pipe 1302. One end of the air distribution pipe is fixedly connected to one end of the hose 1303. The hose 1303 is made of a retractable and high-pressure resistant rubber material, and the quick connectors at both ends of the hose 1303 are respectively provided. It is detachably connected to the air outlet of the air distribution pipe and the metal bellows 1214. The inner walls on both sides of the web frame 1201 are provided with support components for supporting the stripping plate 1203. When demoulding, the air bag 1210 is expanded to push the lifting frame 1211 downward to squeeze the movable frame 1213, driving the stripping plate 1203 to descend smoothly to complete the demoulding. Compared with traditional vibration demoulding, this pneumatic demoulding method can provide uniform and stable demoulding force, the action is gentle and smooth, and no high-decibel noise is generated, which effectively reduces the pollution of the surrounding environment caused by construction and avoids noise nuisance and disputes. At the same time, it avoids the problem of fine cracks in the concrete caused by vibration, and protects the T-beam in all directions.

[0044] In the present invention, a connecting seat 1202 is provided between the two web formworks 12 located at the inner corners, and one end of the connecting seat 1202 is fixed to one side of the web formwork 12 in the horizontal direction, and the bottom of the connecting seat 1202 is hinged to the top of the web formwork 12 in the vertical direction. The two web formworks 12 located at the outer corners are rotatably connected by a rotating part, and the rotating part is composed of two rotating seats connected by pins. The other two adjacent web frames 1201 are hinged, and the top of the side formwork support frame 8 is hinged to the top of the web frame 1201 located at the top. When the angle of the side formwork support frame 8 is adjusted, the web formwork 12 hingedly connected to the side formwork support frame 8 will be detached from the T-beam surface from top to bottom, piece by piece, in an orderly manner. Compared with the large-area instantaneous detachment of the formwork that may occur in the traditional demoulding method, the pulling and impact force on the T-beam surface is greatly reduced, and the serious damage problems such as scratches, chipping and corner chipping caused by the stress concentration on the T-beam surface at the moment of demoulding are avoided.

[0045] In the present invention, the support assembly includes grooves 1204 provided on the inner walls of both sides of the web frame 1201, and the inner walls of the grooves 1204 are slidably provided with support plates 1205, one side of the support plate 1205 and the inner wall of one side of the groove 1204 are fixedly installed with first springs 1206 distributed at equal distances, and both sides of the lifting frame 1211 are hinged to the other sides of the two support plates 1205 with push-pull plates 1207, and the top corners of the support plates 1205 are rotatably connected with sliding rollers 1208 distributed at equal distances, and the stripping template 1203 is attached to the sliding rollers 1208, and the surface of the sliding rollers 1208 is provided with a wear-resistant rubber layer. The stripping plate 1203 provides reliable support, effectively preventing the stripping plate 1203 from being deformed or moved downward due to concrete pressure, ensuring the smooth progress of the pouring work. When the airbag 1210 expands to start the demoulding program, the lifting frame 1211 will pre-drive the support plate 1205 to retract into the groove 1204 through the push-pull plate 1207, making room for the lifting of the stripping plate 1203, and covering the surface of the sliding roller 1208 with a wear-resistant rubber layer, reducing the friction between the stripping plate 1203 and the support plate 1205, making the stripping plate 1203 move more smoothly and silkily, and can also effectively buffer the contact pressure, and fully protect the surface of the stripping plate 1203.

[0046] In the present invention, a plurality of slots 16 are provided on the tops of the two L-shaped side panels 6, and a pull rod 11 is inserted into the two horizontal slots 16. Both ends of the pull rod 11 are screwed with high-strength reinforcement nuts 14 for connection, and anti-loosening gaskets are provided at the connection points. The two L-shaped side panels 6 are reinforced by the pull rod 11 and the high-strength reinforcement nuts 14, which can effectively enhance the connection strength between the L-shaped side panels 6 on both sides, prevent deformation or displacement of the formwork due to lateral pressure during the concrete pouring process, and ensure the dimensional accuracy and structural stability of the T-beam.

[0047] In the present invention, the side form support frame 8 and the web formwork 12 are both Z-shaped, and the side form support frame 8 is attached to the outside of the web formwork 12 , and the two web formworks 12 are attached to both sides of the bottom formwork 3 .

[0048] Second implementation method:

[0049] Please refer to Figure 1 and Figure 2 , based on embodiment 1, this embodiment adds the following structure, so that this application has the function of resisting the lateral pressure of concrete, and the specific settings are as follows: a reinforcement component for reinforcing the side form support frame 8 is provided on the L-shaped side plate 6, and the reinforcement component includes a second hydraulic cylinder 9 fixedly mounted on the L-shaped side plate 6, and the piston end of the second hydraulic cylinder 9 is fixedly mounted with the same door-shaped reinforcement rib 10, and the door-shaped reinforcement rib 10 is attached to the top of one side of the side form support frame 8. The first hydraulic cylinder 7 is used to adjust the side form support frame 8 to rotate around the hinge point with the L-shaped side plate 6, thereby adjusting the inclination of the side form support frame 8, and the second hydraulic cylinder 9 is used to adjust the horizontal position of the door-shaped reinforcement rib 10, thereby adjusting the supporting force of the side form support frame 8. By adjusting the horizontal position of the door-shaped reinforcement rib 10 under the action of the second hydraulic cylinder 9, the side form support frame 8 can be targetedly reinforced, effectively resisting the lateral pressure of concrete, ensuring the overall stability of the formwork structure, and ensuring the casting quality of the T-beam.

[0050] In summary, the working principle of the present invention is as follows: a bottom formwork 3 is laid on a hardened ground 1 as a base for forming the bottom of the T-beam, slide rails 2 are symmetrically installed on both sides, and the bases 5 of the side formwork units 4 are slidably set on the slide rails 2. By sliding the bases 5, the positions of the side formwork units 4 can be easily adjusted. Adjacent side formwork units 4 are fixedly connected with bolts, thereby completing the side assembly of the formwork;

[0051] The top of the L-shaped side plate 6 in the side form unit 4 is rotatably connected to the side form support frame 8 and the web formwork 12 through the mounting seat 15. The first hydraulic cylinder 7 is hinged between the side form support frame 8 and the L-shaped side plate 6. When working, the first hydraulic cylinder 7 extends or shortens, driving the side form support frame 8 to rotate around the hinge point, thereby adjusting the angle of the web formwork 12 to fit the design shape of the T-beam. At the same time, the reinforcement assembly composed of the second hydraulic cylinder 9 and the gate-shaped reinforcement rib 10 plays a role. The second hydraulic cylinder 9 adjusts the horizontal position of the gate-shaped reinforcement rib 10 to reinforce the side form support frame 8, thereby enhancing the ability of the formwork structure to resist lateral pressure during concrete pouring;

[0052] Since the web formwork 12 is composed of multiple hinged web frames 1201, the inner corners are connected by connecting seats 1202, and the outer corners are connected by rotating parts. This hinged structure enables the web formwork 12 to adapt to the complex corners and curves of T-beams. Support plates 1205 are connected to the inner wall grooves 1204 on both sides of the web frames 1201 via first springs 1206. When pouring concrete, the support plates 1205 are extended by the first springs 1206 to provide support for the stripper plate 1203 to prevent it from deforming or moving downward.

[0053] During pouring, a slot 16 is provided on the top of the L-shaped side panels 6 on both sides, which are connected by a tie rod 11 and a high-strength reinforcement nut 14, and an anti-loosening gasket is provided to enhance the connection strength of the L-shaped side panels 6 on both sides, further resist the side pressure of the concrete, ensure the stability of the template structure, and guarantee the dimensional accuracy of the T-beam. At this time, the various parts of the template structure work together to provide a stable space for concrete pouring;

[0054] After pouring is completed, the air pump 1301 is started, and the gas enters the air bag 1210 through the exhaust pipe 1302, the air distribution pipe, the hose 1303 and the metal bellows 1214. The air bag 1210 expands and pushes the lifting frame 1211 to squeeze the movable frame 1213. The movable frame 1213 drives the stripping plate 1203 to descend, realizing demoulding. At the same time, the lifting frame 1211 drives the support plate 1205 to retract into the groove 1204 through the push-pull plate 1207 in advance to avoid hindering the movement of the stripping plate 1203. After demoulding, the movable frame 1213 is reset under the action of the second spring 1215, driving the stripping plate 1203 to return to its initial position. When the first hydraulic cylinder 7 drives the side form support frame 8 to adjust the angle, since the web formwork 12 is hingedly connected to the side form support frame 8, the web formwork 12 will be separated from the T-beam surface from top to bottom, piece by piece and in an orderly manner, reducing the pulling and impact on the T-beam surface and protecting the appearance and structural integrity of the T-beam.

[0055] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
