Description

Technical Field

[0001] The utility model relates to the technical field of concrete frames, in particular to an assembled energy-consuming concrete beam-column node. Background Art

[0002] With the rapid development of technology and the continuous expansion of application fields, prefabricated integral frame structures are widely used in office buildings, shopping malls, hotels, schools and other situations where flexible and changeable building space and functions are required. The frame structure, especially the beam-column connection design, is the focus and difficulty of the prefabricated integral frame structure, which directly determines the strength, deformation, ductility, energy consumption and other performance indicators of the overall structure. These performance indicators are particularly important in earthquake zones and even high-intensity zones.

[0003] The existing beam-column connections are mainly made through sleeve grouting and interlaced steel bars. This connection method is simple in concept and has a reliable force transmission path, but it has high requirements on construction quality and a large amount of wet work on site. In addition, the construction quality cannot be effectively monitored and controlled after construction. In addition, due to the lack of reinforcement measures at the connection nodes, once the concrete at the connection nodes is broken, it endangers the integrity and stability of the overall structure.

[0004] Patent CN113073736A discloses an assembled beam-column connection node, including a precast concrete column, a precast concrete beam and an energy-absorbing component. The energy-absorbing component includes a bending-resistant component, a shear-resistant component, a first connecting plate and a second connecting plate. However, the patent adopts a connecting plate to connect the beam and the column through bolts. The shear force at the connection is only borne by friction and the shear force of the bolts. The node between the beam and the column is not cast as a whole. The connection bearing capacity between the two is weak, and the stability of the overall structure cannot be guaranteed.

[0005] Therefore, a new type of concrete beam-column node is still to be proposed to ensure the reliability and stability of the beam-column node structure. Utility Model Content

[0006] The purpose of the utility model is to provide an assembled energy-consuming concrete beam-column node to ensure the reliability and stability of the beam-column node structure.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] An assembled energy-absorbing concrete beam-column node, comprising:

[0009] concrete longitudinal beams;

[0010] The concrete cross beam is perpendicular to the concrete longitudinal beam and fixedly installed on the concrete longitudinal beam;

[0011] A reinforcement component is installed on the concrete longitudinal beam and the concrete cross beam; the reinforcement component includes a support frame installed on the outside of the concrete longitudinal beam, and the support frame is connected to a connecting plate installed on the concrete cross beam;

[0012] A prefabricated plate is installed inside the concrete beam, and the prefabricated plate is connected to the connecting plate through fasteners;

[0013] The support frame comprises a top support frame located above the concrete beam and a bottom support frame located below the concrete beam, and a buffering member for supporting and buffering is arranged between the top support frame and the bottom support frame.

[0014] Furthermore, the top support frames and the bottom support frames are both symmetrically distributed about the horizontal surface of the concrete longitudinal beam; the two top support frames are connected by fixing bolts, and the two bottom support frames are connected by fixing bolts.

[0015] Furthermore, the support frame is vertically arranged with the corresponding connecting plate, and reinforcing ribs are connected between the support frame and the connecting plate. The combined configuration of the support frame, the connecting plate and the reinforcing ribs can effectively improve the mutual supporting force at the node between the concrete cross beam and the concrete longitudinal beam, ensuring that the beam-column node structure can reliably and stably transmit vertical loads and lateral loads.

[0016] Furthermore, the connecting plate is connected to the prefabricated plate via connecting bolts.

[0017] Furthermore, the connecting bolt passes through the connecting plate, and a corresponding thread groove is provided on one side of the prefabricated plate close to the connecting plate.

[0018] Furthermore, the connecting bolts are symmetrically arranged at both ends of the connecting plate.

[0019] Furthermore, the buffer between the top support frame and the bottom support frame is a cross-shaped buffer. The buffer is located between the top support frame and the bottom support frame, which can suppress the limited expansion and contraction of the side of the concrete beam, thereby achieving buffering and energy dissipation of the connection node area, thereby ensuring the reliability and stability of the beam-column node structure.

[0020] Furthermore, the bottom of the top support frame and the top of the bottom support frame are both provided with hinged parts.

[0021] Furthermore, the buffer member includes a sleeve rod hinged to the bottom support frame, and a support rod hinged to the top support frame.

[0022] Furthermore, the support rod is slidably connected to the inner side of the sleeve rod.

[0023] Furthermore, a support block is connected to the outer side of the support rod, a first buffer spring is fixedly connected between the support rod and the inner side of the sleeve rod, and a second buffer spring is fixedly connected between the support block and the sleeve rod.

[0024] Furthermore, a damping rubber ring is embedded in one end of the support rod located inside the sleeve rod.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] (1) The utility model can ensure that the beam-column node structure can reliably and stably transmit vertical loads and lateral loads by installing support frames and prefabricated panels on the outside of the concrete longitudinal beams, and the buffer located between the top support frame and the bottom support frame can suppress the limited expansion and contraction of the side of the concrete beam, thereby achieving buffering and energy dissipation in the connection node area, thereby ensuring the reliability and stability of the beam-column node structure.

[0027] (2) The buffer component of the utility model can dissipate part of the input energy when an earthquake or wind pressure occurs, thereby improving the stability of the beam-column node connection to cope with various natural or emergency events.

[0028] (3) The utility model provides reinforcing ribs between the support frame and the connecting plate, which can improve the mutual supporting force at the nodes of the concrete cross beam and the concrete longitudinal beam, thereby improving the stability of the overall structure.

[0029] (4) The prefabricated panel of the utility model can be fixed together with the concrete beam when the concrete beam is poured, and the front and rear sides of the support frame are fixed by fixing bolts, thereby improving the convenience of assembling the entire reinforcement structure.

[0041] Embodiment 2:

[0042] An assembled energy-dissipating concrete beam-column node comprises a concrete longitudinal beam 1, a concrete transverse beam 2 and a reinforcement component 3. The concrete transverse beam 2 is perpendicular to the concrete longitudinal beam 1 and fixedly mounted on the concrete longitudinal beam 1.

[0043] like Figure 1-3 As shown, the reinforcement assembly 3 is installed on the concrete longitudinal beam 1 and the concrete cross beam 2, and includes a plurality of support frames 31 installed on the outside of the concrete longitudinal beam 1. Each support frame 31 is connected to a connecting plate 32 installed on the concrete cross beam 2. The support frame 31 is vertically arranged with the corresponding connecting plate 32, and a reinforcing rib 33 is connected between the support frame 31 and the connecting plate 32. The combined configuration of the support frame 31, the connecting plate 32 and the reinforcing rib 33 can effectively improve the mutual support force at the node of the concrete cross beam 2 and the concrete longitudinal beam 1, and ensure that the beam-column node structure reliably and stably transmits vertical loads and lateral loads. A prefabricated plate 37 is installed inside the concrete cross beam 2, and the connecting plate 32 is connected to the prefabricated plate 37 by a connecting bolt 34. The connecting bolt 34 passes through the connecting plate 32, and a corresponding thread groove is provided on the side of the prefabricated plate 37 close to the connecting plate 32. The connecting bolt 34 is symmetrically arranged at both ends of the connecting plate 32.

[0044] The support frame 31 includes a top support frame 311 located above the concrete beam 2 and a bottom support frame 312 located below the concrete beam 2, and a buffer member 36 for supporting and buffering is provided between the top support frame 311 and the bottom support frame 312.

[0046] Embodiment 3:

[0047] See also Figure 1-3In this embodiment, an assembled energy-absorbing concrete beam-column node includes a concrete longitudinal beam 1 and a concrete transverse beam 2. The concrete transverse beam 2 is fixedly mounted on the concrete longitudinal beam 1. The concrete longitudinal beam 1 and the concrete transverse beam 2 are provided with reinforcement components 3 for reinforcement.

[0048] The reinforcement assembly 3 includes four support frames 31, one end of which is slidably connected to the outer side of the concrete longitudinal beam 1. A connecting plate 32 is fixedly connected to the outer side of the support frame 31, and a reinforcing rib 33 is fixedly connected between the connecting plate 32 and the support frame 31. A prefabricated plate 37 is fixedly installed inside the concrete cross beam 2. A connecting bolt 34 with one end penetrating and extending into the interior of the prefabricated plate 37 is fixedly installed on the connecting plate 32, and fixing bolts 35 are fixedly installed on the front and rear sides of the support frame 31.

[0049] In this embodiment, the support frame 31, the connecting plate 32 and the reinforcing ribs 33 located on the outside of the concrete cross beam 2 and the concrete longitudinal beam 1 can improve the mutual support force at the node of the concrete cross beam 2 and the concrete longitudinal beam 1, ensuring that the beam-column node structure can reliably and stably transmit vertical loads and lateral loads.

[0050] Among them, the four support frames 31 are symmetrically distributed in groups of two on the outside of the concrete longitudinal beam 1, and each group of support frames 31 is fixed to the concrete longitudinal beam 1 by fixing bolts 35, so that each group of two support frames 31 is fixed to the outside of the concrete longitudinal beam 1 and the joint with the concrete cross beam 2.

[0051] In addition, the number of fixing bolts 35 is eight, and the eight fixing bolts 35 are symmetrically distributed in groups of two at the ends of the front and rear sides of each group of support frames 31. Each group of fixing bolts 35 is used to fix the ends of each group of support frames 31 placed on the outside of the concrete longitudinal beam 1.

[0052] Secondly, the support frame 31 is in the shape of a "J", and a threaded groove located on the outside of the connecting bolt 34 is opened on the side of the precast plate 37 close to the connecting plate 32. The precast plate 37 can be placed on the concrete beam 2 when the concrete beam 2 is poured and fixed in one day, thereby facilitating the connection plate 32 to be fixed to the precast plate 37 through the connecting bolt 34.

[0053] Then, the number of the connecting bolts 34 is eight, and the eight connecting bolts 34 are symmetrically distributed on the connecting plate 32 in groups of two and are located on the front and rear sides of the reinforcing ribs 33. The reinforcing ribs 33 are used to strengthen the stability of the connection between the connecting plate 32 and the support frame 31.

[0054] See also Figure 2-3In this embodiment, a buffer member 36 for supporting buffering is arranged between the top support frame 31 and the bottom support frame 31. The buffer assembly 36 includes a sleeve rod 361 with one end hinged to the bottom support frame 31, and the inner side of the sleeve rod 361 is slidably connected to a support rod 366 with one end hinged to the top support frame 31. A support block 365 is fixedly connected to the outer side of the support rod 366, a first buffer spring 362 is fixedly connected between the support rod 366 and the inner side of the sleeve rod 361, a second buffer spring 364 is fixedly connected between the support block 365 and the sleeve rod 361, and a damping rubber ring 363 for energy dissipation is embedded at one end of the support rod 366 located on the inner side of the sleeve rod 361. The number of the sleeve rods 361 and the support rods 366 are both four, and the four sleeve rods 361 and the support rods 366 are arranged in groups of two and are distributed in a cross shape between the top support frame 31 and the bottom support frame 31.

[0055] In this embodiment, the buffer member 36 located between the top support frame 31 and the bottom support frame 31 can achieve limited expansion and contraction of the side of the precast concrete beam, thereby achieving buffering and energy dissipation in the connection node area; as well as dissipation of part of the input energy when an earthquake or wind pressure occurs, thereby improving the stability of the beam-column node connection.

[0056] The working principle of the above embodiment is:

[0057] Since the precast panel 37 can be placed on the concrete cross beam 2 for one-day pouring and fixing when the concrete cross beam 2 is poured, it is convenient to fix the connecting plate 32 on the precast panel 37 through the connecting bolts 34. Therefore, after the support frame 31 located on the outer side of the concrete longitudinal beam 1 is fixed by the fixing bolts 35 and the connecting plate 32 is fixed on the precast panel 37 by the connecting bolts 34, it can ensure that the beam-column node structure can reliably and stably transmit vertical loads and lateral loads. The buffer member 36 located between the top support frame 31 and the bottom support frame 31 can drive the support frame 31 to move when the node between the concrete longitudinal beam 1 and the concrete cross beam 2 is deformed. The support rod 366 and the sleeve rod 361 on 1 squeeze the first buffer spring 362 and the second buffer spring 364, and the reset first buffer spring 362 and the second buffer spring 364 can suppress the limited expansion and contraction of the side of the concrete beam, thereby achieving the buffering and energy dissipation of the connection node area; and the dissipation of part of the input energy when an earthquake or wind pressure occurs, thereby improving the stability of the beam-column node connection, and because the prefabricated plate 37 can be fixed together with the concrete beam 2 when the concrete beam 2 is poured, and the front and rear sides of the support frame 31 are fixed by the fixing bolts 35, the convenience of assembling the entire reinforcement structure is improved.

[0058] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
