Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a frame beam structure and a corbel structure thereof. Background Art

[0002] With the advancement of my country's urbanization process, the construction industry has developed rapidly, and various new building structures have emerged. Among them, the frame structure, as a construction technology with reinforced concrete as the main material, has been widely used in construction projects due to its good seismic performance, spatial layout flexibility and high construction efficiency.

[0003] When adding a corridor or roof between two frames, if integral casting is not used, a flexible connection method of adding a corbel on the beam side as a support can be used. In order to ensure the same elevation of the finished surface of the building, the corbel top elevation is lowered, resulting in the corbel bottom elevation being lower than the beam bottom elevation, so the beam support range needs to be increased.

[0004] At present, designers often take measures to increase the height of the cross section, which will result in excessive material consumption. For example, without considering the material cost, when the torque generated by the corbel on the beam is small, the beam can be widened and heightened, and the reinforcement can be increased to increase the beam support range. However, when the torque generated by the corbel on the beam is large, even without considering the material cost, it is impossible to increase the beam support range by adjusting the beam cross section and reinforcement.

[0005] Therefore, it is necessary to propose a frame beam structure and a corbel structure thereof to solve at least one of the above problems. Utility Model Content

[0050] In order to solve the connection problem between the two buildings, it is necessary to set up a corridor between the two buildings, which is supported on the corbels.

[0051] In order to ensure the flatness of the corridor and the floor, the surface of the corbel needs to be lowered according to the design requirements of the corridor structure, so that the frame beam is twisted and the bottom surface of the corbel is lower than the bottom surface of the frame beam.

[0052] The frame beam structure and the corbel structure provided by the utility model can avoid waste of resources caused by raising the beam cross section over the entire length when the bottom elevation of the corbel on the beam side is lower than the bottom elevation of the beam, and at the same time solve the problem of the beam cross section and reinforcement failing to meet calculation requirements due to excessive beam torque.

[0053] The utility model provides a frame beam structure and a corbel structure thereof, and proposes a scheme of adding a torsion-resistant beam between two frame beams and locally adding arms to the frame beam and the torsion-resistant beam. The large torque generated by the corbel is balanced by adding the torsion-resistant beam, and the stiffness of the torsion-resistant beam end is improved by locally adding arms, thereby effectively improving the safety, rationality and economy of the corbel structure.

[0054] Please refer to Figures 1 to 5 In the implementation manner of the present application specification, a corbel structure of a frame beam 2 is provided, and the corbel structure may include: a torsion beam 1, which is used to be arranged between two frame beams 2; a corbel 4, which is arranged on the side of the frame beam 2 away from the torsion beam 1; the lower surface of the corbel 4 is lower than the lower surface of the frame beam 2; a first armpit area 5, which is arranged between the corbel 4 and the frame beam 2 below the lower surface of the frame beam 2; and a second armpit area 6, which is arranged between the corbel 4 and the torsion beam 1 below the lower surface of the frame beam 2.

[0055] In the implementation mode of the present application, by adding an armpit area structure corresponding to the direction of the main and secondary beams, the supporting range of the main beam is expanded, and a locally enhanced beam side corbel 4 connection node is formed to avoid raising the entire length of the beam section; by adding a torsion-resistant beam 1, the large torque generated by the corbel 4 is balanced, providing a convenient and feasible construction solution for the reinforced concrete beam side corbel 4 structure, which can be widely used in reinforced concrete structures.

[0056] When the corbel structure is used to support the corridor structure support or the roof structure support, the mature axil structure construction method can be used for easy implementation; at the same time, it can also avoid increasing the beam cross-section over the entire length, save project costs, reduce material loss, and promote the sustainable development of the construction industry.

[0057] In the implementation manner of the present application, the application of the corbel structure in the frame beam structure is used as an example for expansion and description. The frame beam structure is used to be assembled with a corridor or a roof, and the frame beam structure includes: a frame beam body, the frame beam body includes a plurality of reinforced concrete beams, and the plurality of reinforced concrete beams have two frame beams 2 for being assembled with the corridor or the roof, and the two frame beams 2 are arranged relatively spaced apart; a torsion beam 1, the torsion beam 1 is arranged between the two frame beams 2; a corbel 4, the corbel 4 is arranged on the side of the frame beam 2 away from the torsion beam 1; the lower surface of the corbel 4 is lower than the lower surface of the frame beam 2; a first armpit area 5, the first armpit area 5 is arranged between the part of the corbel 4 and the frame beam 2 below the lower surface of the frame beam 2; a second armpit area 6, the second armpit area 6 is arranged between the part of the corbel 4 and the torsion beam 1 below the lower surface of the frame beam 2.

[0058] Since the frame beam structure includes the above-mentioned corbel structure, the frame beam structure can achieve the technical effect achieved by the corbel structure implementation method by setting the corbel structure. For details, please refer to the specific description of the above-mentioned implementation method, and this application will not repeat it here.

[0059] In the implementation manner of the present application, the application of the corbel structure in a frame beam structure is mainly taken as an example for explanation.

[0060] Please refer to Figure 1 and Figure 2 The frame beam structure mainly includes a frame beam body, a torsion beam 1, a corbel 4, a first axil area 5 and a second axil area 6.

[0061] The frame beam body may include a plurality of reinforced concrete beams, which are overlapped to form the frame beam body. Among the plurality of reinforced concrete beams, there are two frame beams 2 for assembling with the corridor or roof, and the frame beams 2 are main beams. Specifically, the two frame beams 2 are arranged at a relative interval.

[0062] The torsion beam 1 is connected between the two frame beams 2, and the torsion beam 1 is a secondary beam. By arranging the torsion beam 1 between the two frame beams 2, it can be used to resist the torque generated by the vertical load on the corbel 4. The two frame beams 2 are spliced ​​with other concrete beams to form a frame structure, and frame columns 3 can also be arranged under the four corners of the frame structure.

[0063] In this embodiment, in addition to the anti-torsion beam 1 being provided between the two frame beams 2, an armpit area is provided in the direction of the primary and secondary beams, and the vertical force can be dispersed by providing the armpit area. Specifically, the armpit area includes: a first armpit area 5 provided between the part of the corbel 4 below the lower surface of the frame beam 2 and the frame beam 2. The first armpit area 5 may include two, and the two first armpit areas 5 are symmetrically provided about the corbel 4.

[0064] Specifically, the first armpit area 5 is a right-angled triangle block with a first predetermined thickness. When the first armpit area 5 is a right-angled triangle block, since the triangle has the best stability among all structures, it can expand the main beam support range at a lower cost, form a local reinforced beam side corbel 4 connection node, and avoid raising the beam section over the entire length.

[0065] like Figure 5 As shown, the first predetermined thickness b is equal to the lower surface width of the frame beam 2. When the first armpit area 5 is equal to the lower surface width of the frame beam 2, it is more conducive to casting and forming with a lower cost and a more controllable construction method.

[0066] Please refer to Figure 3 In a specific embodiment, the right-angled triangle block has a first right-angled side and a second right-angled side that are perpendicular to each other, the ratio of the side length a1 of the first right-angled side to the side length h1 of the second right-angled side is 2:1, the first right-angled side is located on the frame beam 2, and the second right-angled side is located on the corbel 4.

[0067] In this embodiment, when the length ratio of the first right-angled side located on the frame beam 2 to the second right-angled side located on the corbel 4 is 2:1, it can be ensured that the stress of the overall structure tends to be most reasonable.

[0068] In addition, the second armpit area 6 is also a right-angled triangle block with a second predetermined thickness b as a whole. When the first armpit area 5 is a right-angled triangle block, since the triangle is the most stable structure among all structures, it is combined with the above-mentioned first armpit area 5 to expand the supporting range of the main beam at a lower cost, form a locally enhanced beam side corbel 4 connection node, and avoid raising the entire length of the beam section.

[0069] Please refer to Figure 4 In a specific embodiment, the right-angled triangle block of the second armpit area 6 has a first right-angled side and a second right-angled side that are perpendicular to each other, and the ratio of the length b1 of the first right-angled side to the length h1 of the second right-angled side is 2:1. The first right-angled side is located on the torsion beam 1, and the second right-angled side is located on the corbel 4.

[0070] In this embodiment, when the length ratio of the first right-angled side located on the torsion beam 1 to the second right-angled side located on the corbel 4 is 2:1, it can be ensured that the force of the overall structure tends to be most reasonable.

[0071] Wherein, along the extension direction of the frame beam 2, the width of the corbel 4 is equal to the width of the torsion beam 1, both of which are Figure 3 or Figure 5 The dimension a in the figure is not only more conducive to casting at a lower cost and in a more controllable construction method, but also more reasonable in structural layout.

[0072] like Figure 3 As shown, in some embodiments, the frame beam structure may further include a connecting member for bearing the vertical force of the corbel 4, and the connecting member is sequentially located in the frame beam 2, the first armpit area 5, the corbel 4, the second armpit area 6 and the frame beam 2.

[0073] In this embodiment, the connector includes a hanger 8, which is used to bear the vertical force of the corbel 4. Of course, the specific configuration of the connector can also be in other forms, not limited to the above description, and technicians in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the protection scope of this application.

[0074] Please refer to Figure 4 In this embodiment, the hanging rod 8 is used as an example for illustration. When the connecting member is the hanging rod 8, the number of the hanging rod 8 can be determined according to the size of the frame beam 2. For example, in this embodiment, the hanging rod 8 can include 3 to 4, and two hanging rods 8 are evenly distributed at a certain distance.

[0075] In one embodiment, the frame beam structure may further include anchor bolts 7, and the anchor bolts 7 are used to connect the corbels 4 and the corridor.

[0076] During the actual construction, a structural calculation model is established and the vertical force of the corridor is added for calculation. The type, diameter, spacing and related dimensions of the corbel structure of the steel bars are determined by the designers based on the calculations.

[0077] The torsion beam 1, frame beam 2, frame column 3, corbel 4, first axil area 5 and second axil area 6 are all supported on site, reinforced with steel bars, and anchor bolts 7 are placed. The torsion beam 1, frame beam 2, frame column 3, corbel 4, first axil area 5 and second axil area 6 are cast in an integrated manner, so that the second axil area 6 connects and supports the torsion beam 1 and the corbel 4, and the first axil area 5 connects and supports the frame beam 2 and the corbel 4.

[0078] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0079] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0080] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
