Anti-seismic support structure combined with bidirectional force nodes

Abstract

The utility model relates to an anti-seismic support structure combined with bidirectional force nodes, which comprises a comprehensive support formed by a plurality of vertical rods and cross rods, the tops of the vertical rods are fixedly connected with a top plate, and the corresponding connecting ends of the cross rods and the vertical rods are connected and fixed through rigid connecting pieces; the transverse rod located at the bottom of the comprehensive support is connected with a transverse inclined strut arranged in the horizontal direction, and the free end of the transverse inclined strut is fixedly connected to the bearing column or the constructional column. The transverse rods and the vertical rods of the comprehensive support are rigidly connected through the rigid connecting pieces, and the transverse rods located at the bottom are provided with the transverse inclined struts to be horizontally fixed to a column or a constructional column so as to transmit earthquake force. As the length of the transverse diagonal bracings in the horizontal direction is generally smaller than that of the longitudinal diagonal bracings, loss is saved, and meanwhile the problem that conflicts are prone to occurring when the longitudinal diagonal bracings are arranged is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, and in particular to an earthquake-resistant bracket structure combined with a bidirectional force node. Background Art

[0002] Seismic supports and hangers are divided into lateral seismic supports and hangers and longitudinal seismic supports and hangers. Lateral and longitudinal horizontal force transmission is usually fixed to the top plate by diagonal braces. The corridors of subway stations are narrow, and the lateral diagonal braces conflict with the filling walls on both sides of the corridor. Usually, the horizontal force of the seismic support is transferred to the structural column or a separately installed steel frame. The number of layers of the integrated support is generally 4 to 5. The longitudinal diagonal braces on the bottom layer often conflict with the integrated support poles or pipelines on the rear side, making on-site construction difficult. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a seismic support structure combined with a bidirectional force node.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A seismic support structure combined with a bidirectional force node includes an integrated support composed of multiple vertical bars and horizontal bars, the top of the vertical bar is fixedly connected to the top plate, and the corresponding connecting ends of each horizontal bar and the vertical bar are connected and fixed by a rigid connecting piece; the horizontal bar located at the bottom of the integrated support is connected to a horizontal diagonal brace arranged in the horizontal direction, and the free end of the horizontal diagonal brace is connected and fixed to a load-bearing column or a structural column.

[0006] Furthermore, the rigid connecting member is a connecting sleeve, which has a joint that is sleeved and matched with the cross bar and the vertical bar, and a locking screw is threadedly connected to the outer wall of the joint.

[0007] Furthermore, the top of the vertical rod is fixedly connected to the top plate via an anchor bolt.

[0008] Furthermore, the free end of the transverse diagonal brace is fixedly connected to the load-bearing column or the structural column through an anchor bolt.

[0009] Furthermore, the transverse diagonal braces are arranged in pairs and symmetrically.

[0010] The utility model adopts the above technical solution, and has the beneficial effect that the horizontal bars and vertical bars of the integrated bracket are rigidly connected by rigid connectors, and the horizontal bars at the bottom are provided with horizontal diagonal braces to be fixed horizontally to the columns or structural columns to transmit the earthquake force. Since the horizontal diagonal braces are generally shorter than the longitudinal diagonal braces, the loss is also saved, and the problem of easy conflict of the longitudinal diagonal braces is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0013] Figure 2 for Figure 1 Detailed view at midpoint A. Implementation

[0014] like Figure 1-2 As shown, the utility model is a seismic support structure combined with a bidirectional force node, including a comprehensive support composed of multiple vertical bars 1 and horizontal bars 2, the top of the vertical bar 1 is fixedly connected to the top plate 3, and the corresponding connecting ends of each horizontal bar 2 and the vertical bar 1 are connected and fixed by a rigid connector 4; the horizontal bar 2 located at the bottom of the comprehensive support is connected to a horizontal diagonal brace 5 arranged in the horizontal direction, and the free end of the horizontal diagonal brace 5 is connected and fixed to a load-bearing column or a structural column 6 to transmit seismic force. The horizontal diagonal braces 5 connected to the horizontal bar 2 at the bottom of the comprehensive support are arranged in pairs and symmetrically, and the number and number of layers of the horizontal diagonal braces 5 can be flexibly set according to the load of the comprehensive support without affecting the installation of pipelines.

[0015] The rigid connector 4 is a connecting sleeve, which has a joint that is sleeved and matched with the crossbar 2 and the vertical bar 1, and a locking screw is threadedly connected on the outer wall of the joint.

[0016] The top of the vertical rod 1 is fixedly connected to the top plate 3 by an anchor bolt. The free end of the transverse brace 5 is fixedly connected to the load-bearing column or structural column 6 by an anchor bolt, and the connection between the transverse brace 5 and the crossbar 2 is achieved by bolts passing through the matching connection holes of the two and being locked by nuts.

[0017] The utility model transmits both lateral and longitudinal forces to the bearing column or structural column through a node method, so as to avoid the problem of easy conflict when longitudinal diagonal braces are set. In addition to being suitable for subway walkways, it is also suitable for some renovation projects.

[0018] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
