[0002] A reusable T-beam precast beam formwork device is usually designed as a modular, easily adjustable and durable structure to meet the production needs of T-beams of different specifications and lengths while ensuring construction quality and efficiency.

[0003] Most existing prefabricated formwork devices lack a mechanism for temporarily connecting and positioning the side formwork during assembly. As a result, when the side formwork is not fastened to the bottom formwork during assembly, it is necessary to manually push the side formwork to the bottom formwork for a long time for subsequent fastening of the side formwork, which is troublesome and laborious to operate.

[0004] In addition, although some devices are equipped with mechanisms for temporarily connecting and positioning the side templates, most of these mechanisms cannot directly tighten and seal the side templates and the bottom template, and an additional set of mechanisms for tightening and sealing must be set up, which is not conducive to simplifying the structure of the device and reducing manufacturing costs.

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0048] For the convenience of description, the long side of the bottom template 1 is marked as the left-right direction, and the short side is marked as the front-back direction.

[0049] Please refer to Figures 1 to 11 , an embodiment provided by the present invention:

[0050] The present invention proposes a reusable T-beam prefabricated beam template device, comprising a bottom side template 1, a rectangular slot 101, a rectangular plug hole 102, an inclined guide surface 1021, abutment plane 1022, an L-shaped slot 103, two side templates 2, a long sealing plate 201, a rectangular insert frame 202, a vertical support rod 203, a longitudinal support connecting plate 204, a positioning square sleeve 205, a shaft sleeve 2051, a threaded driving shaft 206, a longitudinal support limiting shaft 207, a positioning ring 208, a driving square rod 3, a driving wedge block 301, a threaded sleeve 302, a hexagonal horizontal inserting shaft 4, a triangular force block 401, a limiting ring 402, a connecting rod 403, an insert block 5, a positioning block 501, a force transmission block 502, a first guide inclined surface 503, a second guide inclined surface 504, and a limiting plane 505. The two side templates 2 are symmetrically inserted and combined on the two long sides of the bottom side template 1.

[0051] Among them, two rows of rectangular slots 101 are symmetrically opened on the two long sides of the bottom side template 1, and two rectangular holes 102 arranged in a staggered manner are opened facing each other at the head ends of the two long sides of the rectangular slots 101. The long sides of the rectangular holes 102 close to the opening ends of the rectangular slots 101 are provided with inclined guide surfaces 1021 and abutment planes 1022 connected end to end, and the inclined guide surfaces 1021 and the abutment planes 1022 are arranged in sequence along the direction close to the opening end of the rectangular holes 102.

[0052] A row of rectangular insert frames 202 corresponding to the number of rectangular slots 101 are welded to the bottom end of the side template 2, and the rectangular insert frames 202 are plugged into and matched with the rectangular slots 101; a hexagonal transverse insert shaft 4 is slidably installed inside the rectangular insert frame 202 through a spring push, and the head end of the hexagonal transverse insert shaft 4 is symmetrically rotatably connected with two connecting rods 403; two insert blocks 5 are slidably installed through the head ends of the two long side walls of the rectangular insert frame 202, and the two insert blocks 5 are staggered with each other.

[0053] Preferably, the head end of the plug block 5 is in a conical structure, and is provided with a first guiding bevel 503, a second guiding bevel 504 and a limiting plane 505, wherein the first guiding bevel 503 and the second guiding bevel 504 are arranged opposite to each other, and the second guiding bevel 504 and the limiting plane 505 are connected end to end. Through the bevel guidance of the first guiding bevel 503, when the rectangular plug frame 202 is plugged into the rectangular slot 101, the plug block 5 can be pushed by the open end of the rectangular slot 101 to automatically slide inward and hide in the rectangular plug frame 202, leaving space on both sides of the rectangular plug frame 202 for normal plug-in assembly of the rectangular plug frame 202 and the rectangular slot 101 without obstacles, refer to Figure 6 .

[0054] Preferably, two force transmission blocks 502 that are staggered up and down are welded to the tail ends of the two plug blocks 5, one of the force transmission blocks 502 is extended, and the head ends of the two connecting rods 403 are rotatably connected to the two force transmission blocks 502; two positioning blocks 501 that are supported upward and downward are welded to the two force transmission blocks 502, and two longitudinal support limit shafts 207 that are staggered up and down are welded between the head end parts of the long side walls of the rectangular plug frame 202, and the two positioning blocks 501 are slidably matched with the two longitudinal support limit shafts 207 through spring pushing.

[0055] When the insert block 5 is slidably aligned with the rectangular slot 101, the spring on the longitudinal support limit shaft 207 can rebound and push out the insert block 5, so that the insert block 5 is automatically plugged into the rectangular slot 101. Figure 6 .

[0056] Preferably, when the rectangular insert frame 202 is inserted into the head end portion of the rectangular slot 101, the insert block 5 is plugged into the rectangular socket 102, the second guide slope 504 and the limiting plane 505 are respectively in contact with the inclined guide surface 1021 and the abutting plane 1022, and when the insert block 5 is plugged into the rectangular socket 102, a sliding gap is maintained between a long side of the rectangular socket 102 away from the insert block 5 and the insert block 5, and a sliding gap is maintained between the head end of the insert block 5 and the tail end blocking side of the rectangular socket 102; under normal conditions and when the insert block 5 is plugged into the rectangular socket 102, a spacing is maintained between the positioning block 501 and the long side wall of the rectangular insert frame 202.

[0057] The plug block 5 is plugged into and matched with the rectangular socket 102 to insert and position the rectangular plug frame 202 in the rectangular slot 101, and the temporarily loosened combined connection of the side template 2 and the bottom template 1 is positioned. Compared with the prior art, the trouble of manually pushing and holding the side template 2 on the bottom template 1 for a long time for subsequent tightening of the side template 2 can be eliminated, and the operation is more convenient and labor-saving. By abutting and blocking the limiting plane 505 with the abutting plane 1022, the plug block 5 can realize the temporary insertion and positioning of the rectangular plug frame 202.

[0058] Two connecting rods 403, two force transmission blocks 502, two plug blocks 5 and hexagonal horizontal plug shaft 4 are connected together to form two crank slider mechanisms. Figure 7Through these two mechanisms, when the two plug blocks 5 are plugged into and matched with the rectangular slots 101, the hexagonal horizontal plug shaft 4 slides toward the inside of the rectangular plug frame 202, and the two plug blocks 5 can be pushed to continuously slide toward the outside of the two rectangular plug holes 102. Moreover, through the inclined guiding principle of the second guiding inclined surface 504 and the inclined guiding surface 1021, when the two plug blocks 5 are continuously pushed, their bodies together with the rectangular plug frame 202 can be continuously pushed and slid toward the tail end (inside) of the rectangular slot 101 at the same time, and the side template 2 and the bottom template 1 are tightly sealed, and the long sealing plate 201 and the L-shaped card slot 103 are tightly fitted and sealed together, so as to prevent the concrete slurry from leaking through the joint gap between the long sealing plate 201 and the L-shaped card slot 103.

[0059] The plug block 5 is provided with an ingenious and reasonable structure and driving method, so that it can be used for temporarily connecting and positioning the side formwork 2 and the bottom formwork 1, and can also be used for continuing to tighten and seal the side formwork 2 and the bottom formwork 1, effectively integrating the temporary connection and positioning function with the tightening and sealing function, and has a dual-purpose use effect. Compared with the prior art, it can save the need for additional tightening and sealing mechanisms for the side formwork 2 and the bottom formwork 1, which helps to simplify the structure of the formwork device and reduce manufacturing costs.

[0060] The sliding gap between the rectangular insert frame 202 and the sealing side at the rear end of the rectangular slot 101 provides a margin for the rectangular insert frame 202 and the side template 2 to continue to slide and seal toward the rear end of the rectangular slot 101; the sliding gap between a long side on the rectangular socket 102 away from the plug block 5 and the plug block 5 provides a margin for the plug block 5 to slide in the rectangular socket 102 toward the rear end of the rectangular slot 101; the spacing between the positioning block 501 and the long side wall of the rectangular slot 101 provides a margin for the plug block 5 to continue to slide toward the inside of the rectangular socket 102; the sliding gap between the head end of the plug block 5 and the sealing side at the rear end of the rectangular socket 102 also provides a margin for the plug block 5 to continue to slide toward the inside of the rectangular socket 102.

[0061] Preferably, two positioning rings 208 are welded at intervals in the middle of the length direction inside the rectangular insert frame 202, the hexagonal transverse insert shaft 4 slides through the two positioning rings 208, and a limiting ring 402 is welded and sleeved on the middle section of the hexagonal transverse insert shaft 4 located between the two positioning rings 208, and a spring is compressed and sleeved on the hexagonal transverse insert shaft 4 between the limiting ring 402 and the positioning ring 208 on the side close to the side template 2, and the thrust of the spring on the hexagonal transverse insert shaft 4 is equal to the total thrust of the two springs on the two longitudinal support limiting shafts 207.

[0062] The two springs on the two longitudinal support limit shafts 207 are used to push and drive the two plug blocks 5 to slide away from each other, and drive the hexagonal transverse plug shaft 4 to slide toward the inside of the rectangular plug frame 202. The spring on the hexagonal transverse plug shaft 4 is used to push and drive the hexagonal transverse plug shaft 4 to slide toward the outside of the rectangular plug frame 202. In this way, the thrust of the spring on the hexagonal transverse plug shaft 4 is equal to the total thrust of the two springs on the two longitudinal support limit shafts 207, which can make the internal and external reverse thrusts acting on the hexagonal transverse plug shaft 4 offset each other and balance each other, push the limit ring 402 to maintain the center position between the two positioning rings 208, and ensure the existence of a spacing between the positioning block 501 and the long side wall of the rectangular slot 101.

[0063] The sliding distance between the limit ring 402 and the positioning ring 208 on the side close to the side template 2 can allow the hexagonal transverse insertion shaft 4 to slide toward the outside of the rectangular insertion frame 202 when the two insertion blocks 5 slide inward to shrink the space, and can also allow the hexagonal transverse insertion shaft 4 to slide toward the outside of the rectangular insertion frame 202 to drive the two insertion blocks 5 to slide inward and be pulled out to disassemble the rectangular insertion frame 202 and the side template 2; the sliding distance between the limit ring 402 and the positioning ring 208 on the side away from the side template 2 can allow the hexagonal transverse insertion shaft 4 to slide toward the inside of the rectangular insertion frame 202 to continuously push the two insertion blocks 5.

[0064] Preferably, a triangular force block 401 is welded to the tail end of the hexagonal transverse insertion shaft 4 protruding from the rectangular insertion frame 202; a longitudinal support connecting plate 204 is welded between the tail ends of every two rectangular insertion frames 202, and two positioning square sleeves 205 are symmetrically welded on the two symmetrically positioned longitudinal support connecting plates 204, and a driving square rod 3 is slidably installed through the two positioning square sleeves 205; a row of driving wedge blocks 301 corresponding to the number of the hexagonal transverse insertion shaft 4 is welded on the side of the driving square rod 3 facing the rectangular insertion frame 202, and when the driving square rod 3 slides forward, the driving wedge blocks 301 come into contact with the inclined surfaces of the triangular force blocks 401; a shaft sleeve 2051 is welded to the top of the two positioning square sleeves 205, and a threaded driving shaft 206 is rotatably installed through the two shaft sleeves 2051, and a threaded sleeve 302 is welded to the top of the middle part of the driving square rod 3, and the threaded driving shaft 206 is screwed through and fitted with the threaded sleeve 302, refer to Figure 7 .

[0065] Through the inclined guiding principle of a row of driving wedge blocks 301 and a row of triangular force blocks 401, the forward sliding driving square rod 3 can push and drive a row of hexagonal horizontal plug shafts 4 to slide toward the inside of a row of rectangular plug frames 202, and control all the plug blocks 5 to continuously push inside the rectangular plug holes 102, so as to complete the top sealing of the side template 2 and the bottom template 1 at one time. This saves the trouble of continuously pushing all the plug blocks 5 in steps to complete the top sealing of the side template 2 and the bottom template 1, and helps to simplify the overall plug-in combination assembly steps of the side template 2 and the bottom template 1, which is convenient and efficient to operate; the threaded driving shaft 206 is used for forward and reverse rotation to drive the threaded driving shaft 206 and the driving square rod 3 to slide back and forth, so as to implement loosening and tightening of all the plug blocks 5;

[0066] It is worth noting that: through the two crank slider mechanisms composed of two connecting rods 403, two force transmission blocks 502, two insert blocks 5 and the hexagonal transverse insert shaft 4, when the two insert blocks 5 slide and hide toward the inside of the rectangular insert frame 202, the hexagonal transverse insert shaft 4 can be pushed and driven to slide toward the outside of the rectangular insert frame 202. At this time, it should be ensured that a row of driving wedge blocks 301 and a row of triangular force blocks 401 are separated and disengaged from each other, and space is left between the row of driving wedge blocks 301 and the row of triangular force blocks 401 for the hexagonal transverse insert shaft 4 to slide toward the outside of the rectangular insert frame 202.

[0067] Preferably, the side formwork 2 is supported inclinedly as a whole, and an L-shaped molding plate is formed at the top end of the side formwork 2, and a long sealing plate 201 is welded to the bottom part of the side formwork 2. After the two side formworks 2 are assembled and installed with the bottom formwork 1, a casting space with a T-shaped structure is formed between the two side formworks 2, the two L-shaped molding plates and the bottom formwork 1, and this casting space can be used to cast and produce T-shaped prefabricated beams.

[0068] Preferably, two L-shaped slots 103 are symmetrically provided at the top of the bottom template 1 near the two long sides, and when the plug block 5 is plugged into the rectangular plug hole 102 , the long sealing plate 201 is docked and mounted with the L-shaped slots 103 .

[0069] Two long fixing plates are symmetrically welded on the bottom part of the two long sides of the bottom template 1. The long fixing plates are provided with screw holes. Figure 3 The top of the L-shaped molding plate is symmetrically threaded with two hanging rings; two vertical support rods 203 are symmetrically welded between the rectangular insert frame 202 and the side template 2.

[0070] Working principle: When in use, the bottom formwork 1 and two long fixed plates are fixed to the ground by collision bolts, and the two side formworks 2 are hoisted and transferred by lifting equipment, and the two side formworks 2 and the bottom formwork 1 are combined and installed. After the two side formworks 2 are combined and installed with the bottom formwork 1, a casting space with a T-shaped structure is formed between the two side formworks 2, the two L-shaped molding plates and the bottom formwork 1, and this casting space can be used to cast and produce T-shaped precast beams.

[0071] When the two side templates 2 and the bottom template 1 are combined and installed, the rectangular plug-in frame 202 is plugged into and matched with the rectangular slot 101. Through the bevel guiding principle of the first guide bevel 503, when the rectangular plug-in frame 202 is plugged into and matched with the rectangular slot 101, the plug-in block 5 can be pushed and driven by the open end of the rectangular slot 101 to automatically slide inward and hide in the rectangular plug-in frame 202, leaving space on both sides of the rectangular plug-in frame 202 for the normal plug-in assembly of the rectangular plug-in frame 202 and the rectangular slot 101 without obstacles. When the plug-in block 5 is slidably aligned with the rectangular slot 101, the spring on the longitudinal support limit shaft 207 can rebound and push out the plug-in block 5, so that the plug-in block 5 is automatically plugged into and matched with the rectangular slot 101; the plug-in block 5 is plugged into and matched with the rectangular socket 102 to plug and position the rectangular plug-in frame 202 in the rectangular slot 101, and the temporarily loosened combined connection of the side template 2 and the bottom template 1 is positioned.

[0072] The two connecting rods 403, the two force transmission blocks 502, the two plug blocks 5 and the hexagonal transverse plug shaft 4 are connected together to form two crank slider mechanisms. Through these two mechanisms, when the two plug blocks 5 are plugged into the rectangular slots 101, the hexagonal transverse plug shaft 4 slides toward the outside of the rectangular plug frame 202, which can push and drive the two plug blocks 5 to continuously slide toward the inside of the two rectangular plug holes 102. Moreover, through the inclined guide principle of the second guide inclined surface 504 and the inclined guide surface 1021, when the two plug blocks 5 are continuously pushed, their bodies together with the rectangular plug frame 202 can be continuously pushed and slid toward the tail end of the rectangular slot 101 at the same time, and the side template 2 and the bottom template 1 are tightly sealed, and the long sealing plate 201 and the L-shaped slot 103 are tightly sealed together to prevent concrete slurry from leaking through the joint gap between the long sealing plate 201 and the L-shaped slot 103.
