Description

Technical Field

[0001] This utility model relates to the field of building support structures, specifically a large-span concrete formwork construction structure. Background Technology

[0002] Large-span concrete formwork construction structures generally refer to the use of specialized formwork in building or civil engineering to support and shape large-span concrete beams, slabs, or arches. Depending on the construction method, concrete beams and slabs are classified as cast-in-place monolithic, precast assembled, and monolithic assembled. Cast-in-place monolithic structures are widely used due to their design flexibility, structural integrity, and high durability.

[0003] For large-span and continuous concrete beam-slab structures, in addition to using formwork to support them during pouring, a corresponding beam formwork support system must be designed to support the formwork. However, existing support systems often neglect the reinforcement of the beam formwork, which leads to the risk of grout leakage and loosening of the beam formwork. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a large-span concrete formwork construction structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-span concrete formwork construction structure, including a steel reinforcement frame, beam formwork, and reinforcing bars, and further including a reinforcement component for reinforcing the beam formwork and a bracing component for supporting the reinforcement component. The reinforcement component includes a base plate and a pair of side plates arranged at both ends of the base plate. The base plate is arranged at the position of the steel reinforcement frame corresponding to the beam formwork and abuts against the bottom of the beam formwork. The side plates installed at both ends of the base plate are threadedly connected to the base plate to clamp and fix the beam formwork.

[0006] As a further improvement of this utility model, the diagonal bracing assembly includes a clamp, an adjusting rod, and an abutting rod installed on the steel reinforcement frame. The clamp is provided with a connecting seat for installing the adjusting rod. The adjusting rod is fixedly connected to the connecting seat by a pin. The abutting rod is threadedly connected to the end of the adjusting rod away from the connecting seat, and the other end of the abutting rod abuts against the side of the base plate.

[0007] As a further improvement of this utility model, the end of the abutting rod used to abut against the base plate is provided with a socket, a plug rod is inserted into the socket, and the end of the plug rod is provided with an abutting interface adapted to the base plate.

[0008] As a further improvement of this utility model, the steel bar frame is also provided with an abutment component to reinforce the side plate. The abutment component includes a limiting rod and retaining rings at both ends of the limiting rod. The limiting rod abuts against the surface of the side plate, and the retaining rings at both ends of the limiting rod are fixedly connected to the steel bar frame.

[0009] As a further improvement of this utility model, the side plate is provided with a groove that mates with the bottom plate, and the bottom plate is provided with a protrusion that mates with the groove.

[0010] The beneficial effects of this utility model are that by reinforcing the beam formwork with reinforcing components, the risk of grout leakage and loosening of the beam formwork is reduced. At the same time, by setting diagonal bracing components and abutment components to reinforce the reinforcing components, the overall device can be made more stable. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-5 As shown, a large-span concrete formwork construction structure includes a steel reinforcement frame 2, a beam formwork 1, and reinforcing bars. It also includes a reinforcement component 3 for reinforcing the beam formwork 1 and a bracing component 4 for supporting the reinforcement component 3. The reinforcement component 3 includes a base plate 32 and a pair of side plates 31 arranged at both ends of the base plate 32. The base plate 32 is arranged at the position of the steel reinforcement frame 2 corresponding to the beam formwork 1 and abuts against the bottom of the beam formwork 1. The side plates 31 installed at both ends of the base plate 32 are threadedly connected to the base plate 32 to clamp and fix the beam formwork 1.

[0019] In this embodiment, the reinforcement component 3 can better strengthen the beam formwork 1 and prevent adverse effects caused by the loosening of the beam formwork 1 during construction. The reinforcement component 3 includes a base plate 32 and a pair of side plates 31 arranged at both ends of the base plate 32. The base plate 32 is arranged at the position of the steel reinforcement frame 2 corresponding to the beam formwork 1 and abuts against the bottom of the beam formwork 1. The base plate 32 is mounted on the steel reinforcement frame 2 and clamps the beam formwork 1 through the side plates 31 at both ends. At the same time, the side plates 31 are threaded to the base plate 32, which can also ensure the connection between the base plate 32 and the side plates 31 is stable and can better clamp the beam formwork 1. In addition, a diagonal brace component 4 is also provided to support the base plate 32 for stability.

[0020] Furthermore, the diagonal bracing assembly 4 includes a clamp 41, an adjusting rod 42, and an abutment rod 43 installed on the reinforcing bar frame 2. The clamp 41 is provided with a connecting seat 46 for installing the adjusting rod 42. The adjusting rod 42 is fixedly connected to the connecting seat 46 by a pin. The abutment rod 43 is threadedly connected to the end of the adjusting rod 42 away from the connecting seat 46, and the other end of the abutment rod 43 abuts against the side of the base plate 32.

[0021] In this embodiment, the diagonal bracing assembly 4 is installed on the steel frame 2 near the reinforcing assembly 3. The diagonal bracing assembly 4 includes a clamp 41, an adjusting rod 42, and an abutment rod 43 installed on the steel frame 2. The clamp 41 connects the diagonal bracing assembly 4 securely to the steel frame 2. The clamp 41 is also provided with a connecting seat 46. The adjusting rod 42 is fixedly connected to the connecting seat 46 by a pin. The angle of the adjusting rod 42 can be adjusted by the pin, allowing the adjusting rod 42 to support the base plate 32 at different angles. The abutment rod 43 is threaded to the end of the adjusting rod 42 away from the connecting seat 46. The threaded connection allows the lengths of the adjusting rod 42 and the abutment rod 43 to be adjusted, allowing the abutment rod 43 to fully abut against the base plate 32.

[0022] Furthermore, the end of the abutting rod 43 that abuts against the base plate 32 is provided with an insertion port, and a plug rod 44 is inserted into the insertion port. The end of the plug rod 44 is provided with an abutting interface that is adapted to the base plate 32.

[0023] In this embodiment, in order to better abut against the base plate 32, the end of the abutment rod 43 was adjusted. The abutment rod 43 is provided with a socket, and a plug rod 44 is inserted into the socket. The end of the plug rod 44 is provided with an abutment interface that is adapted to the base plate 32. In order to better adapt to the shape of abutting against the base plate 32, it is set as L-shaped. In other solutions, the abutment interface can be set as a ball head shape to abut against the side of the base plate 32.

[0024] Furthermore, the steel reinforcement frame 2 is also provided with abutment component 5 to reinforce the side plate 31. The abutment component 5 includes a limiting rod 52 and retaining rings 51 at both ends of the limiting rod 52. The limiting rod 52 abuts against the surface of the side plate 31, and the retaining rings 51 at both ends of the limiting rod 52 are fixedly connected to the steel reinforcement frame 2.

[0025] In this embodiment, the stability of the side plate 31 is a crucial factor. Therefore, abutment components 5 are also provided on both sides of the side plate 31 to reinforce it. The abutment component 5 includes a limiting rod 52 and retaining rings 51 at both ends of the limiting rod 52. The limiting rod 52 abuts against the surface of the side plate 31, and the retaining rings 51 at both ends of the limiting rod 52 are fixedly connected to the steel frame 2. By abutting the limiting rod 52 against the surface of the side plate 31, the side plate 31 is better stabilized. At the same time, the retaining rings 51 on both sides also enable the abutment component 5 to have better overall strength.

[0026] Furthermore, the side plate 31 is provided with a groove 33 that mates with the bottom plate 32, and the bottom plate 32 is provided with a protrusion that mates with the groove 33.

[0027] In this embodiment, in order to better connect the side plate 31 and the bottom plate 32, grooves 33 and protrusions that can fit together are respectively provided on the side plate 31 and the bottom plate 32. The grooves 33 and protrusions facilitate the quick installation of the side plate 31 and the bottom plate 32.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
