Description

Technical Field

[0001] This invention relates to the field of concrete bridge technology, and in particular to a formwork system for a uniform cross-section T-beam. Background Technology

[0002] Precast beam / assembly construction technology divides the bridge superstructure into several beam units along the span direction, prefabricates them in sections at a prefabrication yard, transports them to the bridge site as large components, and uses specialized bridge erection equipment to position the precast beams on the piers. The longitudinal joints between the precast beams are then joined by reinforcing steel bars and cast-in-place concrete to form a complete span of concrete main beam structure. Prestressed concrete T-beams, as a classic type of precast assembled beam, use prestressed steel strands anchored at the beam ends to apply prestress and resist the deflection of the concrete beam. This allows concrete T-beams to be used in bridges with large spans. They offer advantages such as clear stress distribution, convenient maintenance, good economy, and improved project quality, and are widely used in highway and railway bridge construction both domestically and internationally.

[0003] Traditional prestressed concrete T-beams have the following main characteristics: ① The web has a variable cross-section along the longitudinal direction. The end sections are locally reinforced compared to the mid-span section to bear the support reaction force and local stress caused by the prestressing tendons, and a continuous transition section is set from the beam end to the mid-span. ② Due to the large number of variable cross-sections in the beam, the internal steel reinforcement has more than 150 different specifications to accommodate these changes. ③ The prestressing tendons have relatively small diameters, requiring a large number of tendons to meet the prestressing design requirements.

[0004] The uniform cross-section of the web of a T-beam maintains a consistent longitudinal profile, offering significant advantages in the industrialization and automation of T-beam manufacturing. These advantages include: ① Consistent cross-sections effectively simplify concrete formwork structures and facilitate demolding. ② The number of steel reinforcement types can be reduced from over 150 to less than 20, significantly improving the efficiency and quality of automated steel reinforcement processing while reducing processing costs. ③ The use of large-diameter steel strands can reduce the number of prestressed steel strands, decreasing the amount of strand threading required for T-beam processing and further improving processing efficiency.

[0005] Because traditional T-beams use a variable cross-section design along the longitudinal direction, their concrete diaphragms and concrete flanges are integrated. However, post-tensioned prestressed concrete T-beams with a constant cross-section use a constant cross-section design along the longitudinal direction, and their concrete diaphragms and concrete flanges are separate. Therefore, traditional concrete formwork systems cannot meet the requirements of T-beams with a constant cross-section. Summary of the Invention

[0006] The purpose of this invention is to provide a formwork system for T-beams with uniform cross-sections, addressing the problem that traditional concrete formwork systems in the background art cannot meet the requirements of T-beams with uniform cross-sections.

[0007] This invention provides a formwork system for a uniform cross-section T-beam, comprising: A movable platform, wherein bases are provided on both sides of the movable platform, and a plurality of bases are spaced apart along the length direction of the movable platform, and each base is provided with a transverse movement system; Two web plate side molds are located on both sides of the movable platform. The web plate side molds are located above the base. A wing plate template is hinged to the top of the web plate side molds. The transverse system is used to drive the web plate side molds to move. The transverse diaphragm templates are installed on the side mold of the web plate, the transverse diaphragm templates are located below the wing plate templates, and the transverse diaphragm templates are spaced apart along the length direction of the side mold of the web plate.

[0008] The diaphragm template is set on the web side formwork and located below the wing plate template to achieve the separation design of the T-beam wing plate and the T-beam diaphragm, so as to meet the casting requirements of the diaphragm of the T-beam with uniform cross section. Furthermore, the web side formwork is located on both sides of the movable platform. The transverse movement system is used to drive the web side formwork to move, thereby controlling the two plate side formwork to move closer and further away from each other, thereby realizing the opening and closing of the template system and simplifying the closing and demolding of the template system.

[0009] Preferably, a back beam structure is connected to the outer side of the web side mold, and the back beam structure is arranged along the length direction of the web side mold; The lateral movement system is connected to the back beam structure, and the lateral movement system is used to drive the back beam structure to slide downwards at an angle.

[0010] The lateral sliding system drives the back beam structure to slide downwards, thereby causing the web side formwork to move downwards, which facilitates the quick separation of the web side formwork from the cast-in-place T-beam with equal cross-section. This prevents the wing plate formwork from scratching the cast-in-place T-beam with equal cross-section during demolding and protects the appearance quality of the concrete. At the same time, the driving force of the distributed transverse movement system in the back beam structure is avoided, so as to prevent the web side formwork from being directly subjected to force and causing local stress deformation, thus ensuring the cross-sectional accuracy of the T-beam with uniform cross section.

[0011] Preferably, the diaphragm template includes a first side plate, a first top plate, a first bottom plate, and a first end plate. The two first side plates and the first bottom plate form a frame structure. The frame structure is connected to the web side mold. The first end plate is movably connected to the side of the frame structure. The first top plate is detachably connected to the top of the frame structure. It also includes setting a first opening on the side mold of the web plate, the first opening being located above the diaphragm template, and the first opening being fitted with a movable cover plate.

[0012] When pouring T-beam concrete from the top of the formwork system, when the concrete is almost full of the diaphragm formwork, the concrete inside the diaphragm formwork can be vibrated by opening the first top plate. The construction operation is convenient and can effectively reduce the quality defects after the diaphragm is formed. During demolding, the first end plate is removed and the first top plate is opened. At the same time, the movable cover plate of the first opening is removed. The first opening provides additional clearance for the cast diaphragm. The web side mold is tilted and moved downward by the transverse movement system, thereby realizing the demolding of the T-beam.

[0013] Preferably, the first top plate has multiple holes, and the bottom surface of the first top plate is covered with a breathable and waterproof geotextile, which covers the multiple holes.

[0014] By using the holes in the first top plate in conjunction with breathable and waterproof geotextile, the air in the diaphragm concrete slurry can be vented but not discharged, effectively removing air from the inside of the diaphragm formwork and preventing concrete slurry leakage, thereby enhancing the pouring quality of the diaphragm concrete.

[0015] Preferably, the lateral movement system includes a slide rail, a slider, and a telescopic rod. The slider is slidably mounted on the slide rail, and the telescopic rod is used to drive the slider to move along the length direction of the slide rail. The slider is connected to the bottom of the back beam structure, and the slide rail is inclined downward along the length direction of the base.

[0016] Preferably, it further includes a slope adjustment device, which is disposed between the back beam structure and the wing plate template, and the slope adjustment device is used to adjust the tilt angle of the wing plate template.

[0017] Preferably, the back beam structure includes a first transverse back beam, which extends below the wing plate template and connects to the web plate side mold; The slope adjustment device includes an adjusting caliper and an adjusting screw. The adjusting screw is mounted on the first transverse back beam and can move up and down. The top of the adjusting screw is used to abut against the wing plate template. The adjusting caliper is movably mounted on the first transverse back beam and located inside the adjusting screw. The upper part of the adjusting caliper is provided with a stepped edge, which is used to support the wing plate template.

[0018] The adjusting screw controls the height of the wing plate template by moving up and down. In conjunction with the stepped edge support of the adjusting caliper, the angle of the wing plate template can be adjusted, thereby improving the slope accuracy of the wing plate template. After the wing plate template is adjusted, the adjusting screw and the stepped edge of the adjusting caliper jointly support the wing plate template to ensure that the wing plate template is stable and reliable after the angle is fixed, avoid displacement during pouring, and ensure the forming quality of the T-beam wing plate.

[0019] Preferably, a first nut is sleeved on the upper part of the adjusting screw, and the first nut abuts against the top surface of the first transverse back beam; The bottom surface of the wing plate template is provided with a crossbar, and the top of the adjusting screw is connected to a bearing seat, which is snapped onto the crossbar.

[0020] Because the top of the adjusting screw is connected to a bearing seat, and the bearing seat is snapped onto the crossbar, the top of the adjusting screw is fixed. When the height of the screw needs to be adjusted, the adjusting screw is raised or lowered by rotating the first nut, thereby adjusting the angle of the wing plate template.

[0021] Preferably, it further includes a locking nut, which is sleeved on the lower part of the adjusting screw and is used to abut against the bottom surface of the first transverse back beam.

[0022] After adjusting the height of the adjusting screw, put the locking nut on the adjusting screw, and then rotate the locking nut until it abuts against the bottom surface of the first transverse back beam to lock and fix the adjusting screw.

[0023] Preferably, it also includes a guardrail assembly, the guardrail assembly including a guardrail and a transverse rib disposed at the bottom of the guardrail, the transverse rib having a pin at one end near the web side mold, the pin extending downward; The back beam structure includes a vertical back beam, on which a sleeve is provided, and the pin is used to insert into the sleeve.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The formwork system for a uniform cross-section T-beam of the present invention includes a movable platform, a base, a transverse sliding system, web side molds, and diaphragm molds. The diaphragm molds are set on the web side molds and located below the wing plate molds to achieve a separate design between the T-beam wing plate and the T-beam diaphragm, thereby meeting the diaphragm casting requirements of the uniform cross-section T-beam. Furthermore, the web side molds are located on both sides of the movable platform, and the transverse sliding system is used to drive the web side molds to move, thereby controlling the two side molds to move closer and further away from each other, thus realizing the opening and closing of the formwork system, simplifying the mold closing and demolding of the formwork system, and improving the construction efficiency of the uniform cross-section T-beam.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0037] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0038] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0039] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0040] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0041] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0042] Example 1 like Figures 1-10 As shown, this embodiment discloses a formwork system for a uniform cross-section T-beam, comprising: A movable platform 1 is provided on both sides of the movable platform 1, and multiple bases 2 are spaced apart along the length of the movable platform 1. Each base 2 is provided with a transverse movement system 3. Two web plate side molds 4 are located on both sides of the movable platform 1. The web plate side molds 4 are located above the base 2. The top of the web plate side molds 4 is hinged with a wing plate template 8. The transverse system 3 is used to drive the web plate side molds 4 to move. The transverse diaphragm template 5 is set on the web side mold 4. The transverse diaphragm template 5 is located below the wing plate template 8, and the transverse diaphragm template 5 is set at intervals along the length direction of the web side mold 4.

[0043] In this embodiment, the movable platform 1 provides a bottom platform for the T-beam pouring, and the two side bases 2 are spaced apart along the length of the movable platform 1 to provide an installation foundation for the transverse moving system 3. At the same time, the web side formwork 4 is located on both sides of the movable platform 1. The transverse moving system 3 is used to drive the web side formwork 4 to move, thereby controlling the two web side formwork 4 to move closer and further away from each other, thus realizing the opening and closing of the formwork system, simplifying the closing and demolding of the formwork system, and improving construction efficiency. Furthermore, the transverse diaphragm formwork 5 is set on the web side formwork 4 and located below the wing plate formwork 8 to realize the separation of the T-beam wing plate and the T-beam transverse diaphragm, so as to meet the pouring construction of the T-beam with uniform cross-section.

[0044] The uniform cross-section T-beam consists of a web, a transverse diaphragm connected in the middle of the web, and a flange connected to the top of the web. The transverse diaphragms are spaced apart along the length of the web, and there is a gap between the transverse diaphragms and the flanges.

[0045] The template system for the uniform cross-section T-beam in this embodiment mainly includes a movable platform 1, web side molds 4, diaphragm templates 5, movable end plates 20, and movable top plates. The top surface of the movable platform 1 is used as the base plate of the template system. The bottoms of the two web side molds 4 abut against the sides of the movable platform 1. The diaphragm templates 5 are installed on the web side molds 4 and are connected to the web side molds 4. The bottom of the movable end plates 20 abuts against the top surface of the movable platform 1, and the movable end plates 20 are detachably connected to the ends of the web side molds 4. The movable top plate is installed on the top of the wing plate templates 8, thereby forming the mold cavity of the uniform cross-section T-beam. When casting a uniform cross-section T-beam, the formwork system is first opened by removing the movable top plate and movable end plate 20. Then, the two web side forms 4 are moved away from each other by the transverse movement system 3, thus opening the formwork system. The T-beam reinforcement cage is then hoisted and placed on the movable platform 1, and the formwork is closed. When closing the formwork, the web side forms 4 are first controlled to move closer to each other until they abut against the movable platform 1. Then, the movable end plate 20 and movable top plate are installed, and then concrete is poured. After the concrete has solidified, the demolding operation is carried out. The movable top plate and movable end plate 20 are first removed, and then the two web side forms 4 are moved away from each other by the transverse movement system 3. The movable platform 1 is then used to send the demolded uniform cross-section T-beam into the steam curing chamber for steam curing, thus realizing the prefabrication of the uniform cross-section T-beam.

[0046] In one or more implementations, such as Figure 1 , Figure 8 As shown, a back beam structure 7 is connected to the outside of the web side mold 4, and the back beam structure 7 is arranged along the length direction of the web side mold 4. The transverse system 3 is connected to the back beam structure 7, and the transverse system 3 is used to drive the back beam structure 7 to slide downward at an angle.

[0047] The transverse system 3 drives the back beam structure 7 to slide downwards, thereby driving the web side formwork 4 to move downwards, which facilitates the quick separation of the web side formwork 4 from the cast equal cross-section T-beam, and avoids the wing plate formwork 8 from scratching the cast equal cross-section T-beam during demolding, thus protecting the appearance quality of the concrete. At the same time, the driving force of the back beam structure 7 disperses the transverse movement system 3, avoiding the direct force on the web side formwork 4 and causing local stress deformation, thus ensuring the cross-sectional accuracy of the T-beam with uniform cross-section.

[0048] In optional implementations, such as Figure 3 , Figure 4 As shown, the diaphragm template 5 includes a first side plate 51, a first top plate 52, a first bottom plate 53 and a first end plate 54. The first side plate 51 and the first bottom plate 53 form a frame structure, which is connected to the web side mold 4. The first end plate 54 is movably connected to the side of the frame structure, and the first top plate 52 is detachably located on the top of the frame structure. It also includes setting a first opening 10 on the web side mold 4, the first opening 10 being located above the transverse diaphragm template 5, and the first opening 10 being fitted with a movable cover plate 6.

[0049] In this embodiment, the diaphragm template 5 is composed of two first side plates 51, a first top plate 52, a first bottom plate 53 and a first end plate 54. The two first side plates 51 and the first bottom plate 53 form a frame structure, which is fixedly connected to the web side template 4. The first end plate 54 is movably connected to the side of the frame structure, thereby facilitating the removal of the first end plate 54; The first top plate 52 is detachable on the top of the frame structure, making it easy to remove the first top plate 52. It also includes a rectangular frame 56, with multiple vertical steel plates at the bottom of the rectangular frame 56. Multiple sets of card seats are provided on the first side plate 51, with two card seats in each set, and through holes on the card seats. The vertical steel plate of the rectangular frame 56 also has through holes. After the rectangular frame 56 is installed on top of the frame structure, the vertical steel plate extends into two brackets, and then a pin passes through the two brackets and the vertical steel plate to fix the vertical steel plate to the brackets, thereby installing the rectangular frame 56 on top of the frame structure. The first top plate 52 is bolted to the rectangular frame 56, as shown below. Figures 3-5 .

[0050] When pouring T-beams, traditional transverse diaphragm formwork lacks a vibration channel, which can easily lead to quality defects such as honeycomb and pitting. However, in this implementation, when pouring T-beam concrete from the top of the formwork system, the concrete inside the transverse diaphragm formwork 5 can be vibrated by opening the first top plate 52 when the concrete is almost filled. This makes the construction operation convenient and can effectively reduce quality defects after the transverse diaphragm is formed.

[0051] Meanwhile, traditional diaphragm formwork is prone to damage to the edges and corners of the diaphragm during demolding. However, in this embodiment, during demolding, the first end plate 54 is removed and the first top plate 52 is opened, while the movable cover plate 6 of the first opening 10 is removed. The transverse movement system 3 drives the web side formwork 4 to tilt downwards, thereby achieving the demolding of the T-beam. Figure 4 ; During the demolding process, the first opening 10 provides additional avoidance space for the cast diaphragm. Since the first opening 10 is located above the diaphragm template 5, it is equivalent to setting an avoidance space above the diaphragm template 5. When the web side mold 4 moves downward at an incline, the design of the first opening 10 effectively avoids interference contact between the web side mold 4 and the cast diaphragm, that is, it avoids the situation where the web side mold 4 located above the diaphragm template 5 collides with the cast diaphragm when the web side mold 4 is demolded downward at an incline.

[0052] In one or more implementations, such as Figure 9As shown, the transverse system 3 includes a slide rail 31, a slider 32, and a telescopic rod 33. The slider 32 is slidably mounted on the slide rail 31, and the telescopic rod 33 is used to drive the slider 32 to move along the length of the slide rail 31. The slider 32 is connected to the bottom of the back beam structure 7, and the slide rail 31 is inclined downward along the length of the base 2.

[0053] The slide rail 31 and the slider 32 form a stable guiding structure, which, together with the linear drive of the telescopic rod 33, improves the movement accuracy of the web side mold 4; Meanwhile, the slide rail 31 is inclined downward along the length of the base 2 so that the slider 32 can move downward, thereby driving the web side mold 4 to move downward.

[0054] In optional implementations, such as Figure 9 As shown, the base 2 includes an inclined plate 21 and a transverse support plate 22 connected to each other. The inclined plate 21 is located on the side close to the movable platform 1. The slide rail 31 is installed on the inclined plate 21. The telescopic end of the telescopic rod 33 is hinged to the slider 32, and the fixed end of the telescopic rod 33 is hinged to the transverse support plate 22.

[0055] The inclined plate 21 provides an inclined mounting base for the slide rail 31 so that the slide rail 31 can tilt downwards, while the transverse support plate 22 provides a mounting base for the telescopic rod 33, and the telescopic end of the telescopic rod 33 is hinged to the slider 32, and the fixed end of the telescopic rod 33 is hinged to the transverse support plate 22, so that the telescopic rod 33 can push the slider 32.

[0056] In this embodiment, as Figure 8 As shown, the back beam structure 7 includes a first transverse back beam 71, a vertical back beam 72, a second transverse back beam 76, and a connecting rod 77. The first transverse back beam 71 is located below the wing plate template 8 and is connected to the web plate side template 4. The second transverse back beam 76 is located below the first transverse back beam 71, and the second transverse back beam 76 is connected to the web side mold 4. The first transverse back beam 71 and the second transverse back beam 76 are connected at one end away from the web side mold 4 to the vertical back beam 72. A connecting rod 77 is provided on the second transverse back beam 76, and the bottom of the connecting rod 77 is connected to the top of the slider 32.

[0057] In one or more implementations, such as Figure 2 As shown, it also includes a slope adjustment device 100, which is disposed between the back beam structure 7 and the wing plate template 8. The slope adjustment device 100 is used to adjust the tilt angle of the wing plate template 8.

[0058] In traditional T-beam formwork, the formwork structure at the wing plate lacks a dedicated angle adjustment mechanism. The slope adjustment of the wing plate relies on temporary supports, which has low precision and poor stability. It cannot adapt to the slope requirements of the wing plate in different bridge designs and has poor versatility. In this embodiment, the wing plate template 8 uses a slope adjustment device 100 to replace temporary supports, thereby improving the slope adjustment accuracy of the wing plate template 8 and ensuring the construction quality of the wing plate.

[0059] In this embodiment, the wing plate template 8 is hinged to the top of the web side mold 4, and the slope adjustment device 100 is located at the end of the wing plate template 8 away from the web side mold 4, so as to adjust the slope of the wing plate template 8.

[0060] Preferably, the wing plate template 8 and the web side template 4 are hinged together by hinges. Specifically, multiple hinges are spaced apart along the length of the web side template 4, and the web side template 4 is connected to the wing plate template 8 by the hinges so that the wing plate template 8 can rotate relative to the web side template 4.

[0061] In optional implementations, such as Figure 8 As shown, the back beam structure 7 includes a first transverse back beam 71, which extends to the bottom of the wing plate template 8 and is connected to the web plate side template 4. like Figure 6 As shown, the slope adjustment device 100 includes an adjustment caliper 101 and an adjustment screw 102. The adjustment screw 102 is mounted on the first transverse back beam 71 and can move up and down. The top of the adjustment screw 102 is used to abut against the wing plate template 8. The adjusting caliper 101 is movably installed on the first transverse back beam 71 and is located inside the adjusting screw 102. The upper part of the adjusting caliper 101 is provided with a stepped edge, which is used to support the wing plate template 8.

[0062] The adjusting screw 102 controls the height of the end of the wing plate template 8 away from the web side mold 4 by moving up and down, so that the wing plate template 8 rotates relative to the web side mold 4, thereby realizing the slope adjustment of the wing plate template 8 and improving the slope accuracy of the wing plate template 8. After the slope of the wing plate template 8 is adjusted, the adjusting caliper 101 is moved so that the stepped edge of the adjusting caliper 101 supports the wing plate template 8 to effectively support the wing plate template 8. After the wing plate template 8 is adjusted, the adjusting screw 102 and the stepped edge of the adjusting caliper 101 jointly support the wing plate template 8, ensuring that the angle of the wing plate template 8 is fixed and stable and reliable, avoiding displacement during pouring, and ensuring the forming quality of the T-beam wing plate.

[0063] In optional implementations, such as Figure 6 As shown, a first nut 103 is sleeved on the upper part of the adjusting screw 102, and the first nut 103 abuts against the top surface of the first transverse back beam 71; The bottom surface of the wing plate template 8 is provided with a crossbar 81, and the top of the adjusting screw 102 is connected to a bearing seat 104, which is snapped onto the crossbar 81.

[0064] Since the top of the adjusting screw 102 is connected to the bearing seat 104, and the bearing seat 104 is snapped onto the crossbar 81, the top of the adjusting screw 102 is in a fixed state. When it is necessary to adjust the height of the screw 102, the first nut 103 is rotated to raise or lower the adjusting screw 102, thereby adjusting the angle of the wing plate template 8. Meanwhile, the design of the support seat 104 increases the contact area between the adjusting screw 102 and the wing plate template 8, while the design of the crossbar 81 avoids the adjusting screw 102 from directly contacting the wing plate template 8, thus preventing local deformation of the wing plate template 8 and ensuring the accuracy of the wing plate template 8.

[0065] In optional implementations, such as Figure 7 As shown, the support seat 104 includes a grooved plate 1042 and a vertical plate 1041. The two vertical plates 1041 are arranged opposite each other on the side of the support seat 104 away from the groove. The top end of the adjusting screw 102 is hinged to the vertical plate 1041. The grooved plate 1042 is engaged with the first transverse back beam 71, thereby fixing the top end of the adjusting screw 102 and restricting the rotation of the adjusting screw 102 so that the adjusting screw 102 can be controlled to rise or fall by rotating the first nut 103.

[0066] In optional implementations, such as Figure 6 , Figure 7 As shown, it also includes a locking nut 105, which is sleeved on the lower part of the adjusting screw 102 and is used to abut against the bottom surface of the first transverse back beam 71.

[0067] After adjusting the height of the adjusting screw 102, put the locking nut 105 on the adjusting screw 102, and then rotate the locking nut 105 until it abuts against the bottom surface of the first transverse back beam 71 to lock and fix the adjusting screw 102.

[0068] In an optional embodiment, a second pad 107 is provided between the locking nut 105 and the first transverse back beam 71, and a first pad 106 is provided between the first nut 103 and the first transverse back beam 71.

[0069] In one or more implementations, such as Figure 10 As shown, it also includes a guardrail assembly 200, which includes a guardrail 201 and a horizontal rib 202 provided at the bottom of the guardrail 201. The horizontal rib 202 is provided with a pin 203 at one end near the web side mold 4, and the pin 203 extends downward. The back beam structure 7 includes a vertical back beam 72, on which a sleeve 73 is provided, and a pin 203 is used to insert into the sleeve 73.

[0070] The guardrail assembly 200 provides safety protection for construction workers and reduces the risk of falling from heights. Furthermore, the plug-in connection between the pin 203 and the sleeve 73 enables the guardrail assembly 200 to be quickly assembled and disassembled, improving construction efficiency. It also has good compatibility with the formwork system and does not affect other processes.

[0071] In this embodiment, the movable platform 1 consists of a box-shaped structure and rollers. The box-shaped structure is assembled and welded from steel plates, and its length is determined according to design requirements. The rollers are installed at the bottom of the box-shaped structure to push the movable platform 1.

[0072] Example 2 like Figure 3 , Figure 5 As shown, based on Embodiment 1, this embodiment discloses a template system for a T-beam with a uniform cross-section. In an optional embodiment, a plurality of holes 521 are provided on the first top plate 52, and a breathable and waterproof geotextile 55 is laid on the bottom surface of the first top plate 52, covering the plurality of holes 521.

[0073] By using the holes 521 in the first top plate 52 in conjunction with the breathable and waterproof geotextile 55, the air in the diaphragm concrete slurry can be vented but not discharged, effectively removing air from the inside of the diaphragm formwork 5 and preventing concrete slurry leakage, thereby enhancing the pouring quality of the diaphragm concrete.

[0074] Specifically, when pouring T-beam concrete, when the concrete is almost filled to the diaphragm, the diaphragm can be vibrated by opening the first top plate 52. Then, a breathable and waterproof geotextile 55 is laid on the top of the diaphragm formwork 5. The first top plate 52 is then turned back to the top and fixed. Then, the T-beam concrete is poured from the top of the formwork system to complete the T-beam concrete pouring operation.

[0075] The breathable and waterproof geotextile 55 is placed between the first top plate 52 and the rectangular frame 56, and the breathable and waterproof geotextile 55 is pressed by the first top plate 52.

[0076] Example 3 like Figure 7 As shown, based on Embodiment 1, this embodiment discloses a template system for a T-beam with a uniform cross section. The adjusting caliper 101 includes a vertical plate 111 and a horizontal plate 112 connected to each other. The end of the vertical plate 111 away from the horizontal plate 112 is provided with a stepped edge, and the horizontal plate 112 is provided with a sliding groove 113. The first transverse back beam 71 is provided with an ear plate 74, and the horizontal plate 112 abuts against the ear plate 74; It also includes a fixing bolt 9, which passes through the ear plate 74 and the slide groove 113, and the two ends of the fixing bolt 9 are fastened to the ear plate 74 and the horizontal plate 112 by nuts.

[0077] The adjusting caliper 101 includes a vertical plate 111 and a horizontal plate 112 that are connected to each other, and the vertical plate 111 and the horizontal plate 112 are perpendicular to each other; Since the horizontal plate 112 is provided with a sliding groove 113, the sliding groove 113 allows the horizontal plate 112 to move horizontally along the ear plate 74, thereby adjusting the horizontal movement of the caliper 101, and thus realizing the adjustment of the position of the caliper 101 according to the support requirements of the wing plate template 8, so that the stepped edge of the caliper 101 can effectively support the wing plate template 8.

[0078] During adjustment, first loosen the nut at the top of the fixing bolt 9, then move the adjusting caliper 101. After the adjusting caliper 101 supports the wing plate template 8, tighten the nut at the top of the fixing bolt 9 to fix the adjusting caliper 101.

[0079] Example 4 like Figure 10 As shown, based on Embodiment 1, this embodiment discloses a template system for a T-beam with a uniform cross-section. A baffle 75 is also provided on the vertical back beam 72, and the baffle 75 is located below the sleeve 73. It also includes a diagonal brace 204, one end of which is connected to the horizontal rib 202, and the other end of which abuts against the vertical back beam 72. The top of the baffle 75 abuts against the diagonal brace 204.

[0080] The top of the baffle 75 abuts against the inclined support leg 204. The baffle 75 provides a support platform for the inclined support leg 204, thereby transferring part of the weight of the guardrail 201 to the baffle 75 through the inclined support leg 204, and then to the vertical back beam 72. Furthermore, after the pin 203 and the diagonal brace 204 are installed on the vertical back beam 72, the horizontal rib 202, the diagonal brace 204 and the vertical back beam 72 form a triangular structure, which enhances the overall stability of the guardrail assembly 200, prevents the guardrail assembly 200 from becoming unstable, and improves the reliability of protection.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
