AI Technical Summary
In the existing method of reinforcement of prefabricated building structures, a layered structure is formed between the reinforcement layer wrapped on the beam and the beam, resulting in a reduction in the reinforcement effect compared to the simultaneous stress.
By opening a communication port on the beam, a connecting casting body is formed between the cast beam body and the original beam, ensuring that both are subjected to stress at the same time, and components such as support formwork, support columns and cast formwork are reinforced to increase the load capacity of the beam.
The reinforcement effect of the beam is improved, avoiding the reduction of load capacity caused by reinforcement, and enhancing the overall load-bearing capacity of the beam.

Description
Technical Field
[0001] The present application relates to the technical field of house beam reinforcement, and in particular to a house beam reinforcement structure for an assembled building structure. Background Art
[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.
[0003] In prefabricated building structures, beams play an important supporting role in the entire building and play an important role in house support and building structure. For beams, slabs, columns and other structures of the house, they are not only the most common house structure, but also the most important structure. They are the prerequisite for ensuring the safe use of the house. Many houses will have quality problems after being used for a long time and need to be reinforced, generally the beams of the prefabricated building structure are reinforced.
[0004] The existing prefabricated building structure beam reinforcement usually uses a frame to wrap around the beam, and then uses pillars to support the frame. Since the top of the beam is in contact with the floor layer, the reinforcement layer wrapped on the beam and the beam are a layered structure. The reinforcement layer and the beam are subjected to different forces, and the reinforcement effect is reduced compared to when they are subjected to force at the same time. Utility Model Content

[0007] The supporting formwork and the pouring formwork are spliced in the length direction of the beam;
[0008] The supporting formwork, the pouring formwork and the floor slab on the house beam form a pouring cavity.
[0009] By adopting the above technical scheme, when casting a new beam, a connecting opening is opened on the beam so that a connecting casting body is formed between the cast beam and the original beam, so that the original beam and the new cast beam are kept in a common stress state, avoiding the state where one beam is stressed and the other is not stressed. When dismantling the formwork, only the casting formwork needs to be removed, and the support column and the support formwork are used as new supporting components to support the beam, thereby reinforcing the beam and increasing the load capacity of the beam.
[0010] Optionally, it also includes a first reinforcement component, which is used to strengthen the load capacity of the beam at the connecting port.
[0011] By adopting the above technical solution, the opening on the beam can easily change the load capacity of the original beam, and the first reinforcement component can compensate for the load reduction caused by the opening.

[0013] By adopting the above technical solution, before opening the connecting port, the first reinforcing plate is fixed on the beam, and then the first reinforcing rod is installed above the connecting port. The two first reinforcing plates and the first reinforcing rod form an I-shaped structure to increase the load capacity of the beam above the connecting port, so as to compensate for the loss of load capacity caused by opening the connecting port.
[0014] Optionally, a plurality of the first reinforcing rods are provided, and the plurality of the first reinforcing rods are arranged in a linear array along the length direction of the beam.
[0015] By adopting the above technical solution, multiple first reinforcement rods are installed in a linear array above the connecting port to increase the load capacity.
[0016] Optionally, a plurality of the first reinforcement rods are provided, and the plurality of the first reinforcement rods are arranged in an arc-shaped array along the length direction of the beam.
[0017] By adopting the above technical solution, compared with the linear array method, the arc-shaped force-bearing structure formed by the arc array has a better bearing capacity.
[0018] Optionally, the first reinforcement assembly further includes a support rod, and both ends of the first reinforcement plate are fixedly connected to the support template via the support rod.
[0019] By adopting the above technical solution, part of the load loss caused by opening the connecting opening is transferred to the supporting formwork through the supporting columns, thereby reducing the deformation of the beams.
[0020] Optionally, it also includes a second reinforcement component, which includes a second reinforcement rod, which passes through the supporting formwork, and both ends of the second reinforcement rod are respectively located on the outer sides of the vertical sides of the supporting formwork, and the part of the second reinforcement rod located in the casting cavity passes through the connecting port.
[0021] By adopting the above technical solution, the strength of the cast body cast through the connecting port is increased, and the connection strength between the original beam and the newly cast beam body is improved.
[0022] Optionally, the support column is a telescopic column with adjustable length.
[0023] By adopting the above technical solution, on the one hand, the height of the supporting formwork is adjusted, and on the other hand, the supporting column forms an interference fit relationship between the supporting formwork and the first reinforcement plate, thereby better reducing the load loss caused by opening the connecting port.
