Especially in large-span building applications, the size and weight of the beams limit the possibility of optimizing their performance. At the same time, the traditional on-site cast-in-place construction method is not only inefficient, but the construction quality is affected by many factors, making it difficult to ensure consistency. In addition, the large amount of waste and noise pollution generated during the construction process is contrary to the current green building concept advocated. Therefore, the development of a new beam-column structure that can both improve structural performance and adapt to the needs of modern construction has become an urgent problem to be solved.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Reference Figures 1 and 2As shown, the utility model provides an assembled prefabricated modular concrete arched beam-column structure.

[0021] Example 1

[0022] It includes frame columns 1 and frame beams 2. Several frames are arranged vertically. The frame beams are connected between two adjacent frame beams. The frame beams and frame columns are made of cast-in-place concrete.

[0023] A prefabricated arched armpit 3 is provided at the connection between the frame column and the frame beam, and the prefabricated arched armpit is made of prefabricated parts; vertical ribs 4 are protruding from the upper surface of the prefabricated arched armpit, and horizontal ribs 5 are protruding from the side of the prefabricated arched armpit; the protruding ends of the vertical ribs are fixed to the steel bars of the frame beam, and the protruding ends of the horizontal ribs are fixed to the steel bars of the frame column; during the casting process of the frame column and the frame beam, the prefabricated arched armpit, the frame beam and the frame column form a whole.

[0024] In this embodiment, prefabricated arched arms are provided at the connection between the frame beams and the frame columns, and the prefabricated arched arms are fixed to the frame beams and the frame columns through the vertical ribs on their upper surfaces and the horizontal ribs on their sides. Subsequently, the prefabricated arched arms, the frame columns, and the frame beams are formed into a whole through on-site casting, thereby improving the connection strength between the frame beams and the frame columns and increasing their bearing capacity. Combining the arched structure with prefabricated assembly technology and utilizing the natural mechanical advantages of the arched beams, the structural bearing capacity is improved while ensuring aesthetics. At the same time, the prefabricated modular production method simplifies the on-site installation process, effectively improving construction efficiency and quality controllability, and reducing environmental pollution, meeting the current development needs of green buildings.

[0025] In Example 1, preferably, in order to ensure the reliability of the connection of the prefabricated arch armpits on the frame beams and frame columns, a number of horizontal reinforcements are horizontally arranged in the prefabricated arch armpits, and are arranged at intervals along the length of the frame column in the vertical direction; a number of vertical reinforcements are vertically arranged in the prefabricated arch armpits, and are arranged at intervals along the length of the frame beam in the horizontal direction.

[0026] In addition, the spacing of the horizontal bars matches the spacing of the stirrups in the frame columns, and the spacing of the vertical bars matches the spacing of the stirrups in the frame beams; thus facilitating the binding and fixing of the horizontal and vertical bars. The extended portions of the horizontal and vertical bars meet the anchorage length requirements of the steel bars, which is conducive to the steel bars being able to fully exert their material strength.

[0027] Example 2

[0028] The structure and principle of Example 2 are similar to those of Example 1, except that: an oblique arcuate rib 6 is further provided at the bottom of the prefabricated arch armpit, and a plurality of oblique arcuate ribs are arranged at intervals in the horizontal direction inside the prefabricated arch armpit; the ends of the horizontal ribs and the vertical ribs located inside the prefabricated arch armpit are fixed on the oblique arcuate ribs, making the steel cage inside the prefabricated arch armpit more integrated, more stable and solid.

[0029] In Example 2, a spacing of at least 2 cm is reserved between the lower surfaces 7 of the precast arched arms of the oblique curved reinforcement. This spacing is set based on the dimensions of the precast arched arms. This reserved spacing between the bottom of the oblique curved reinforcement and the arch base meets the required concrete cover thickness, helps prevent steel bar oxidation and corrosion, and effectively protects the concrete.

[0030] Preferably, at least two parallel oblique arcuate ribs are included. In the embodiment shown in the figure, three oblique arcuate ribs are provided.

[0031] Among them, the vertical reinforcement adopts the form of U-shaped stirrups, the bottom of the U-shaped stirrups is connected to the oblique arc reinforcement, and the oblique arc reinforcement is located directly above the U-shaped stirrups.

[0032] The utility model also provides a building comprising any of the above-described assembled prefabricated modular concrete arched beam-column structures.

[0033] Principle of this utility model:

[0034] The frame columns and frame beams are reinforced concrete components, all of which are cast in situ. The prefabricated arched armpits are composed of horizontal bars, vertical U-shaped stirrups, oblique arc bars, and arched armpit concrete, and are prefabricated in the factory. The horizontal bars are arranged vertically along the sides of the arched armpit concrete, and the steel bars in the inner and outer areas of the concrete must be of a certain length. The vertical U-shaped stirrups are continuous U-shaped steel bars, which are arranged horizontally along the arched armpit concrete. The bottom of the steel bar must extend to near the bottom of the arch, and the top must extend to a certain length; the oblique arc bars are arranged along the arched bottom curved surface of the arched armpit concrete, and the steel bar must maintain a certain distance from the bottom surface of the arch; after the prefabricated arched armpits are prefabricated and transported to the project site, the templates are spliced ​​and the frame columns and frame beams are cast on site. When the prefabricated components and the cast-in-situ components are formed into a whole, an assembled prefabricated modular concrete arched beam-column structure is obtained. During the on-site construction of frame columns and frame beams, the steel cage is tied and fixed to the horizontal and vertical reinforcements on the outside of the prefabricated arch axil concrete, making the connection between the cast-in-place components and the prefabricated components stronger and the force transmission performance better.

[0035] Once the prefabricated arch haunches are completed and transported to the project site, they are assembled into finished components and then joined to the formwork. The reinforcement cages for the frame columns and beams are then tied and concrete poured. Prefabrication of complex components improves construction quality, reduces complexity, and significantly saves time.

[0036] The above are merely preferred embodiments of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope of protection of the present invention.
