Description

Technical Field

[0001] This invention relates to a casting formwork support platform device and its usage method, particularly a casting formwork support platform device and its usage method for cast-in-place construction of bridge cap beams. Background Technology

[0002] Bridge cap beams (also known as bridge cap girders) are an important component of the bridge superstructure. Located atop the piers or abutments, they span the piers laterally, serving a crucial supporting function. They directly support the bridge deck slabs (such as T-beams and box girders) and transfer the bridge deck load to the lower piers or abutments, ultimately distributing it to the foundation. The erection methods for bridge cap beams are mainly divided into cast-in-place and precast hoisting methods. Therefore, the casting formwork support platform device used for cast-in-place bridge cap beam construction is an important construction device. Among the existing casting formwork support platform devices used for cast-in-place bridge cap beam construction, the specific operation flow of the cast-in-place method... The process involves the construction workers first wrapping the clamps around the outside of the pier column, then tightening them using bolts passed through the pre-drilled holes in the clamps. This ensures the clamps fit snugly against the pier column surface, achieving initial fixation. After the clamps are secured, the workers place the I-beams on top of the clamps and then connect and fix the I-beams to the clamps using bolts (depending on the actual construction situation, support plates or other supporting structures may also be installed between the I-beams and the clamps). Finally, the casting template for the cap beam is installed on the I-beams and the top of the pier column. However, this method of cap beam erection still has certain drawbacks: First, during the pouring of the cap beam for a pier, the vibration operation lasts for several hours. The high-frequency vibration causes the preload of the bolts connecting the clamps to the pier to continuously decrease. After a period of time, the loosening of some bolts reduces the friction between the clamps and the pier, preventing the clamps from tightly fitting the pier and affecting the stability of the entire support structure. Furthermore, the I-beams and clamps are also connected by bolts, lacking tight connections and locking reinforcement measures. This prevents the vibration energy from being effectively transferred and dispersed, causing both the clamps and the I-beams to bear significant vibration stress, further reducing the structure's load-bearing capacity. Secondly, during current construction, each time a clamp is installed, workers must first hoist the clamp to the pier, then manually, with the aid of small hoisting equipment, wrap the clamp around the pier and tighten it with bolts one by one. This process requires multiple people working together, and the installation of each clamp takes a considerable amount of time. Similarly, installing the I-beams requires multiple steps such as hoisting, alignment, and fixing. After the cap beam is poured, the clamps and I-beams need to be removed. In the long-term construction of bridges with numerous piers, the frequent repetition of clamp and I-beam installation and removal processes gradually accumulates the time spent on installation and removal, resulting in a need to improve construction efficiency. This invention explores and studies the technical problem of installing clamps on piers with bolts and nuts by using the transmission capacity generated by the vibration operation through elastic energy storage as a technical feature of the installation state.

[0041] This invention designs a method for using a casting formwork support platform device for cast-in-place construction of bridge cap beams. The steps are as follows: the support frame is used as an upper frame, the clamping frame assembly is used to clamp and fix the pier column, the damping spring is used to buffer and support the support frame, and the transmission capacity generated by the vibration operation is realized by the elastic energy storage to achieve the installation state.

[0042] The technical effect of the above technical solution is that it highlights the transmission capacity generated by the elastic energy storage and vibration operation as a technical feature of the installation state, and introduces its application in the technical field of the method of using the casting formwork support platform device for the cast-in-place construction of bridge cap beams.

[0043] This invention comprises the following steps: When it is necessary to install the cast-in-place formwork for the bridge cap beam on the pier, the lifting hook is connected to the ear seat part I of the support frame located on the ground support frame. Using lifting machinery, the support frame is lifted and placed between the piers, so that the inner end face of the longitudinal part of the frame is pressed against the pier, the cylinder part is in a telescopic state, the lower end plate of rod part I contacts the beam part, and rod part I moves within the elongated hole accommodating hole body I and ear seat part III, thereby lifting the seat part I, ear plate part, and beam part. The guide rail... The upper inclined part of part II moves inward on the lower inclined part of guide rail part I. The rod moves inward in the transverse through hole of seat part I and the middle transverse through hole of ear plate part, so that spring part I is in a compressed state. The outer side of hoop acts on the pier, so that the two corresponding hoops on the support frame hug the pier. At the same time, seat part II moves upward with seat part I, so that top rod part moves upward in cylinder part III and sliding cap part moves upward in cylinder part I. When the sliding cap part is in the upper position of tongue block part, the spring... Under the elastic energy storage effect of spring part II, the tongue block moves outward in the convex cavity of cylinder part II, so that the upper end face of the outer end of the tongue block contacts the lower end face edge of the sliding cap, locking cylinder part I. The wire rope on the clamp is installed in the transverse through hole of the end of the ear plate, so that the wire rope on the clamp is in a taut state. The ends of the wire rope on the clamp are connected to each other through the wire rope buckle, and the lifting hook is separated from ear part I, so that the cylinder is in an extended state, and the lower end of rod part I... The plate section is separated from the beam section, and the frame section is lowered. The frame section is placed on the upper end face of the cylinder section I and the outer end face of the upper plate section of the spring seat section, thus completing the installation on the pier. The formwork for the in-situ construction of the bridge cap beam is assembled on the frame section, and the in-situ construction of the bridge cap beam is carried out. After the in-situ construction of the bridge cap beam is completed, the lifting hook is connected to the ear seat section I, the wire rope buckle at the end of the wire rope on the clamp is removed, and the wire rope on the clamp is taken out from the transverse through hole at the end of the ear plate section. The outer ends of the ropes are wrapped around the pier, and the outer ends of the ropes are connected together by wire rope buckles, thus fixing the outer ends of the ropes to the pier. As the support frame is lifted upwards, the upper inclined portion of guide rail II moves outwards on the lower inclined portion of guide rail I. Under the elastic energy storage of spring I, the rod moves outwards in the transverse through-hole of seat I and the middle transverse through-hole located in the ear plate. The outer side of the hoop separates from the pier, and seat III moves upwards on cylinder I. The teeth of seat III move upward in the receiving groove, and cylinder III moves upward in the top rod. The upper end face of the ring contacts the tongue block, causing spring II to be in a compressed state. The tongue block retracts into cylinder II. The outer end of the rope is separated from the pier through the wire rope hook. The top rod and sliding cap fall with the ring to release cylinder I from locking. The frame is separated from the pier, the support frame is placed on the ground support frame, and the lifting hook is separated from ear seat I.

[0044] The technical effects of the above solutions are as follows: they enable the installation and connection of the lower frame on the pier, the installation and fixing of the lower frame for the cast-in-place formwork of the bridge cap beam, and the absorption and treatment of the transmission capacity generated by the vibration operation by the intermediate body.

[0045] The beneficial effects of this invention are as follows: First, in this application, a hydraulic cylinder is used as the core drive to control the coordinated operation of the clamp support and the integrated locking part. From the clamp clamping the pier column, the boss locking and reinforcing the mounting frame and the I-beam and clamp half-leaf to form an integrated locking support structure of the I-beam, mounting frame, clamp assembly and pier column, to unlocking the connection between the mounting frame and the I-beam and the clamp half-leaf resetting, the entire process does not require construction personnel to perform complex installation and dismantling operations manually, which greatly saves labor costs and significantly improves installation and dismantling efficiency. In the long bridge construction, as the number of cap beams increases, the construction time is greatly shortened and the construction efficiency is improved.

[0046] Secondly, in this application, the I-beams, mounting frames, clamping assemblies, and pier columns are integrated and locked together, making the entire support structure a stable whole. The integrated design enhances the rigidity and integrity of the support structure, effectively resisting the vibration generated by concrete pouring and vibration during the subsequent cap beam pouring process. This ensures that the structure will not deform or displace due to uneven stress or external interference during the construction of the bridge cap beam, thus guaranteeing the safety of the construction process. In this technical solution, the support frame and damping spring are basic components and essential technical features of the invention. The support beam, lifting telescopic cylinder, clamp, tongue cylinder seat, release pin seat, and rope are functional components and features that achieve other technical effects of the invention. The design of these technical features, including seat part I, ear plate part, beam part, receiving hole body I, frame part, ear seat part I, guide rail part I, receiving hole body II, cylinder part, rod part I, ear seat part II, ear seat part III, clamp part, guide rail part II, spring part I, rod part, seat part II, cylinder part I, cylinder part II, top rod part, sliding cap part, tongue block part, spring part II, receiving groove, spring part III, spring seat part, seat part III, cylinder part III, and ring part, are technical features that comply with the Patent Law and its implementing regulations.

[0047] In this technical solution, the transmission capacity generated by the elastic energy storage and vibration operation in the installation state is realized by a damping spring.

[0048] In this technical solution, the transmission capacity generated by the vibration operation through elastic energy storage is used as the support frame, clamping frame assembly and damping spring in the installation state as an important technical feature. In the technical field of casting formwork support platform device and usage method for bridge cap beam cast-in-place construction, it has novelty, inventiveness and practicality. The terminology in this technical solution can be explained and understood by patent literature in this technical field. Attached Figure Description

[0094] A method for using a casting formwork support platform device for cast-in-place construction of bridge cap beams includes the following steps: When it is necessary to install the casting formwork for cast-in-place construction of bridge cap beams on the piers, connect the lifting hook to the ear seat part I22 of the support frame 2 located on the ground support frame. Use lifting machinery to lift the support frame 2 and place the frame part 21 between the piers, so that the inner end face of the longitudinal part of the frame part 21 is pressed against the pier, so that the cylinder part 31 is in a telescopic state, the lower end plate of the rod part I32 contacts the beam part 13, and the rod part I32 moves in the elongated hole that accommodates the hole body I14 and the ear seat part III34, so that the seat part I11, The ear plate portion 12 and the beam portion 13 are lifted, the upper inclined portion of the guide rail portion II 42 moves inward on the lower inclined portion of the guide rail portion I 23, the rod portion 44 moves inward in the transverse through hole of the seat portion I 11 and the middle transverse through hole of the ear plate portion 12, so that the spring portion I 43 is in a compressed state, the outer side of the hoop portion 41 acts on the pier column, so that the two corresponding hoop portions 41 on the support frame 2 hug the pier column, and at the same time, the seat portion II 51 moves upward with the seat portion I 11, so that the top rod portion 54 moves upward in the cylinder portion III 62, and the sliding cap portion 55 moves upward in the cylinder portion I 52. When the sliding cap 55 is positioned above the tongue block 56, under the elastic energy storage action of the spring part II 57, the tongue block 56 moves outward in the convex cavity of the cylindrical part II 53, causing the upper end face of the outer end of the tongue block 56 to contact the edge of the lower end face of the sliding cap 55, thus locking the cylindrical part I 52. The wire rope on the clamp 4 is installed in the transverse through hole at the end of the ear plate part 12, so that the wire rope on the clamp 4 is in a taut state. The ends of the wire rope on the clamp 4 are connected to each other through the wire rope buckle, and the lifting hook is separated from the ear seat part I 22, so that the cylinder part 31 is in an extended position. In its extended state, the lower end plate of rod I32 is separated from beam 13, and frame 21 is lowered. Frame 21 is placed on the upper end face of cylinder I52 and the outer end face of the upper end plate of spring seat 82, thus completing the installation on the pier. The casting formwork for the bridge cap beam is assembled on frame 21, and the bridge cap beam is cast in place. After the bridge cap beam is cast in place, the lifting hook is connected to ear seat I22, the wire rope buckle at the end of the wire rope on clamp 4 is removed, and the wire rope on clamp 4 is taken out from the transverse through hole at the end of ear plate 12. The outer end of rope 7 is wrapped around the pier, and the outer ends of rope 7 are connected together by wire rope buckles, thereby fixing the outer ends of rope 7 to the pier. The support frame 2 is lifted upwards. The upper inclined portion of guide rail part II 42 moves outwards on the lower inclined portion of guide rail part I 23. Under the elastic energy storage action of spring part I 43, rod part 44 moves outwards in the transverse through-hole of seat part I 11 and the middle transverse through-hole of ear plate part 12. The outer side of hoop part 41 separates from the pier. Seat part III 61 moves upwards on cylinder part I 52. The teeth of seat part III 61 move upwards in receiving groove 58. Cylinder part III 62 moves upwards in top rod part 54.The upper end face of the ring 63 contacts the tongue block 56, compressing the spring part II 57. The tongue block 56 retracts into the cylinder part II 53. The outer end of the rope 7 is separated from the pier via the wire rope hook. The top rod part 54 and the sliding cap part 55 descend with the ring 63, releasing the locking of the cylinder part I 52. The frame part 21 is separated from the pier, the support frame 2 is placed on the ground support frame, and the lifting hook is separated from the lug part I 22.

[0095] In verifying this invention, the inventors abandoned the existing technical feature of installing the clamp onto the pier using bolts and nuts. Instead, they first proposed a technical feature where the transmission capacity generated by the vibration operation is consumed by elastic energy storage as the installation state. This resulted in the first unexpected technical effect: enabling the clamping installation of the pier through motion conversion, improving the efficiency of installing the casting template for the bridge cap beam. The second unexpected technical effect: enabling the support frame 2 to support the support beam 1, lifting telescopic cylinder 3, clamp 4, tongue cylinder seat 5, pin release seat 6, and rope 7, and achieving the placement of the support frame 2 on the pier through hoisting, improving the installation effect of the casting template for the bridge cap beam. The third unexpected technical effect: enabling the clamping and fixing of the pier by the support beam 1, lifting telescopic cylinder 3, and clamp 4, optimizing the installation operation of the casting template for the bridge cap beam. The fourth unexpected technical effect: enabling the damping spring 8 to provide buffer support for the support frame 2. This improved the transmission capacity generated by vibration operation, resulting in the fifth unexpected technical effect: the support frame 2 was supported by the tongue-shaped seat 5, the pin-detaching seat 6, and the rope 7, eliminating the impact of the transmission capacity generated by vibration operation on the support beam 1. This resulted in the sixth unexpected technical effect: the high-altitude bolt rotation operation was eliminated, improving the safety performance of the pouring formwork installation process for bridge cap beams. This resulted in the seventh unexpected technical effect: the continuous operation of lifting machinery and lifting telescopic cylinder 3 was used to clamp and fix the pier, and the continuous operation of lifting machinery and rope 7 was used to separate the pier, expanding the needs for in-situ pouring of bridge cap beams on piers of different heights. This resulted in the eighth unexpected technical effect: the force of the support beam 1 on the support frame 2 was processed by the 42-48° α, generating a reverse retention force on the support beam 1, improving the stability of the pouring formwork support platform device.

[0096] In the second embodiment of the present invention, the support frame 2, the clamping frame assembly and the damping spring 8 are interconnected in such an installation state that the transmission capacity generated by the vibration operation is consumed by the elastic energy storage.

[0097] In this embodiment, the damping spring 8 is connected to the support frame 2 and the clamping frame assembly in a manner that provides buffer support.

[0098] In this embodiment, the clamping frame assembly is configured to include a support beam 1, a lifting telescopic cylinder 3, and a clamp 4.

[0099] In this embodiment, a first accessory device is also included and disposed between the support frame 2 and the clamping frame assembly. The first accessory device is configured to include a tongue holder 5, a release pin holder 6, and a rope 7.

[0100] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the support frame 2 is used as an upper frame, the clamping frame assembly is used to clamp and fix the pier column, the damping spring 8 is used to buffer and support the support frame 2, and the transmission capacity generated by the vibration operation is realized by the elastic energy storage to achieve the installation state.

[0101] The second embodiment of the present invention is based on the first embodiment. This invention has the following characteristics: 1. Due to the design of support frame 2, clamping frame assembly and damping spring 8, support frame 2 is used as an upper frame, clamping frame assembly is used to clamp and fix the pier column, and damping spring 8 is used to buffer and support support frame 2. The transmission capacity generated by vibration operation is consumed by elastic energy storage as the installation state, which solves the technical problem of installing clamps on pier columns with bolts and nuts. Therefore, the support strength of the formwork for cast-in-place construction of bridge cap beam is improved.

[0102] 2. Due to the design of support beam 1, lifting telescopic cylinder 3 and clamp 4, a tight and fixed connection was achieved on the pier column.

[0103] 3. The design of the tongue holder 5, the pin release holder 6, and the rope 7 enables the support frame 2 to be supported.

[0104] 4. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0105] 5. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0106] Other technical features that connect the support frame 2, clamping frame assembly and damping spring 8 in the installation state with the transmission capacity generated by the elastic energy storage and vibration operation are also embodiments of the present invention. Furthermore, the technical features of the above embodiments can be combined in any way. In order to meet the requirements of the Patent Law, Patent Implementation Regulations and Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

Other modifications to the solution provided by the present invention, additions or reductions of features or steps, or application of the present invention to other technical fields similar to the present invention, all fall within the protection scope of the present invention.
