Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a building connection node. Background Art

[0002] Most existing adjacent building structures are connected by aerial corridors, most of which are steel structure corridors, and there is a trend of corridors being located higher and higher and having longer spans.

[0003] Existing technologies primarily use rigid or articulated supports to connect steel corridors to existing building structures, such as welding or screw connections. These connections are secured to existing buildings using these supports. Temperature and seismic forces can generate significant thermal stress and seismic forces in the structure. The more complex the connection design, the more severe the damage, potentially leading to corridor collapse. Utility Model Content

[0004] The purpose of the utility model is to provide a building connection node that can release temperature pressure and ensure the seismic safety of the building structure.

[0005] In order to achieve the above objectives, the present invention provides a building connection node, comprising:

[0006] Column;

[0007] beam body;

[0008] A connecting frame, the connecting frame comprising a first plate and a second plate, the first plate being connected to the column, and the second plate being vertically disposed on the first plate;

[0009] A sliding support, the sliding support includes a first seat body, a spherical lining plate and a second seat body arranged in sequence from bottom to top, the first seat body is installed on the second plate body, the top of the first seat body has a spherical concave surface, the convex end of the spherical lining plate is placed on the spherical concave surface, the spherical lining plate can slide on the spherical concave surface, the lower end surface of the second seat body is connected to the end of the spherical lining plate away from its convex surface, and the upper end surface of the second seat body is connected to the beam body.

[0010] Furthermore, a first rib is connected between the first plate body and the second plate body, and the first rib is located above the second plate body.

[0011] Furthermore, two first ribs are connected between the first plate body and the second plate body, and the two first ribs are arranged with the sliding support spaced apart.

[0012] Furthermore, a second rib is connected between the first plate body and the second plate body, and the second rib is located below the second plate body.

[0013] Furthermore, a plurality of second ribs are connected between the first plate body and the second plate body, and the plurality of second ribs are arranged at intervals.

[0014] Furthermore, the building connection node further includes a fixing screw, which passes through the first plate and is inserted into the column.

[0015] Furthermore, the building connection node also includes a plurality of the fixing screws, which are arranged in a rectangular interval. The plurality of the vertically distributed fixing screws are located between the first rib and the sliding support. Among the plurality of the laterally distributed fixing screws located on the lower side, one fixing screw is arranged between every two adjacent second ribs, and the plurality of the laterally distributed fixing screws located on the upper side are all located above the beam body.

[0016] Furthermore, the first seat body and the spherical liner are made of Q355B steel.

[0017] Compared with the prior art, the building connection node of the embodiment of the present utility model has the following beneficial effects: the top of the first seat body has a spherical concave surface, and one end of the convex surface of the spherical lining is placed on the spherical concave surface. The spherical lining plate can slide on the spherical concave surface. When the beam body and the column body are affected by temperature and produce overall deformation, the spherical lining plate and the spherical concave surface of the first seat body can slide relative to each other, thereby releasing the structural pressure generated by the overall deformation; under the action of an earthquake, structural stress is generated between the beam body and the column body due to inertia, which can easily cause damage to the connection between the beam body and the column body. The sliding support allows relative displacement between the column body and the beam body, which can reduce the horizontal seismic response of the building structure and thus ensure its seismic safety.

[0028] Furthermore, the terms "first," "second," and the like are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0029] The technical solution of the present utility model is further described below with reference to the embodiments and drawings.

[0030] like Figure 1 、 2As shown, a building connection node of an embodiment of the present invention includes: a column 1; a beam 2; a connecting frame 3, the connecting frame 3 includes a first plate 301 and a second plate 302, the first plate 301 is connected to the column 1, and the second plate 302 is vertically arranged on the first plate 301; a sliding support 4, the sliding support 4 includes a first seat 401, a spherical lining 402 and a second seat 403 arranged in sequence from bottom to top, the first seat 401 is installed on the second plate 302, the top of the first seat 401 has a spherical concave surface 4011, the convex end of the spherical lining 402 is placed on the spherical concave surface 4011, the spherical lining 402 can slide on the spherical concave surface 4011, the lower end surface of the second seat 403 is connected to the end of the spherical lining 402 away from its convex surface, and the upper end surface of the second seat 403 is connected to the beam 2.

[0031] Based on the above technical solution, the top of the first seat 401 has a spherical concave surface 4011, and the convex end of the spherical lining 402 is placed on the spherical concave surface 4011. The spherical lining 402 can slide on the spherical concave surface 4011. When the beam 2 and the column 1 are affected by temperature and produce overall deformation, the spherical lining 402 and the spherical concave surface 4011 of the first seat 401 can slide relative to each other, thereby releasing the structural pressure generated by the overall deformation; under the action of an earthquake, structural stress is generated between the beam 2 and the column 1 due to inertia, which can easily cause damage to the connection between the beam 2 and the column 1. The sliding support 4 allows relative displacement between the column 1 and the beam 2, which can reduce the horizontal seismic response of the building structure and thus ensure its seismic safety.

[0032] Preferably, a first rib 303 is connected between the first plate 301 and the second plate 302, and the first rib 303 is located above the second plate 302. The first rib 303 can increase the structural strength between the first plate 301 and the second plate 302, and increase the connection strength between the second plate 302 and the first plate 301.

[0033] More preferably, two first ribs 303 are connected between the first plate 301 and the second plate 302, and the two first ribs 303 are spaced apart by a sliding support 4. The two first ribs 303 are spaced apart by the sliding support 4 to optimize the structural stress, so that the two first ribs 303 simultaneously bear the weight of the beam 2, resulting in a more uniform stress distribution. Even when the beam 2 and the column 1 are relatively displaced due to external influences, the structure of the connecting frame 3 can be ensured to be unaffected.

[0034] More preferably, a second rib 304 is connected between the first plate 301 and the second plate 302, and the second rib 304 is located below the second plate 302. The second rib 304 can increase the structural strength between the first plate 301 and the second plate 302, and increase the supporting capacity of the second plate 302 and the sliding support 4 on the beam 2.

[0035] More preferably, a plurality of second ribs 304 are connected between the first plate 301 and the second plate 302, and the plurality of second ribs 304 are arranged at intervals. The provision of the plurality of second ribs 304 can greatly reduce the possibility of the second plate 302 bending relative to the first plate 301, thereby ensuring the structural strength of the connecting frame 3.

[0036] More preferably, the building connection node further includes a fixing screw 5 , which passes through the first plate 301 and is inserted into the column 1 .

[0037] More preferably, the building connection node also includes a plurality of fixed screws 5, and the plurality of fixed screws 5 are arranged at intervals in a rectangular shape. The plurality of vertically distributed fixed screws 5 are located between the first rib 303 and the sliding support 4. Among the plurality of laterally distributed fixed screws 5 located on the lower side, a fixed screw 5 is arranged between every two adjacent second ribs 304, and the plurality of laterally distributed fixed screws 5 located on the upper side are all located above the beam body 2. The multiple vertically distributed fixing screws 5 are located between the first rib 303 and the sliding support 4. Among the multiple laterally distributed fixing screws 5 located on the lower side, a fixing screw 5 is arranged between every two adjacent second ribs 304. The multiple laterally distributed fixing screws 5 located on the upper side are all located above the beam 2. Each fixing screw 5 is not hindered by the sliding support 4 and the beam 2 when installed on the column 1. When the fixing screw 5 needs to be replaced, there is no need to remove the beam 2 from the sliding support 4 again. The fixing screws 5 can be directly disassembled and assembled one by one when the connecting frame 3 is installed on the column 1, which greatly improves the convenience of the fixing screw 5.

[0038] Preferably, the first base 401 and the spherical lining plate 402 are made of Q355B steel. The first base 401 and the spherical lining plate 402 are made of high-strength, wear-resistant, and corrosion-resistant materials to increase the service life of the building connection node.

[0039] In summary, the embodiment of the present invention provides a building connection node, the top of its first seat 401 has a spherical concave surface 4011, and one convex end of the spherical lining 402 is placed on the spherical concave surface 4011. The spherical lining 402 can slide on the spherical concave surface 4011. When the beam body 2 and the column body 1 are affected by temperature and produce overall deformation, the spherical lining 402 and the spherical concave surface 4011 of the first seat body 401 can slide relative to each other, thereby releasing the structural pressure generated by the overall deformation; under the action of an earthquake, structural stress is generated between the beam body 2 and the column body 1 due to inertia, which can easily cause damage to the connection between the beam body 2 and the column body 1. The sliding support 4 allows relative displacement between the column body 1 and the beam body 2, which can reduce the horizontal seismic response of the building structure and thus ensure its seismic safety.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
