Abstract

This utility model discloses a side-mounted structure for a seismic bracing system with adjustable installation height, relating to the field of seismic bracing technology. It includes a W-shaped steel section, a side-mounted base, and a bolt assembly. The W-shaped steel section includes a central web, inclined webs, flanges, and end connecting plates.

Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, and in particular to a side-mounted structure for a seismic bracing with adjustable installation height. Background Technology

[0002] In building electromechanical installation projects, seismic bracing needs to be flexibly adapted to the installation scenario based on the pipeline laying location. Besides top-mounted scenarios such as concrete wall tops and steel beam bottoms, many pipelines, such as fire risers and power cable trays, need to be side-mounted and fixed along vertical bases such as walls and columns. Currently, side-mounted seismic bracing typically adopts a rigid connection structure between the side-mounted base and the steel profile: the side-mounted base is fixed to the vertical base with expansion bolts, and the steel profile is connected to the side-mounted base with bolts through pre-set corresponding mounting holes.

[0003] However, vertical foundations, especially cast-in-place walls and brick columns, are prone to issues such as verticality deviations and insufficient surface flatness, leading to discrepancies between the installation height of the steel profiles and the design values ​​during construction. In existing side-mounted structures, the mounting holes of the side-mounted base and the steel profiles are designed to correspond one-to-one, and the mounting holes on the steel profiles must maintain a large interval to ensure structural strength, making it impossible to flexibly adjust the installation height of the steel profiles. To accommodate deviations, additional holes must be drilled in the side-mounted base or steel profiles, which not only increases construction costs and extends the construction period but also damages the structural integrity of the components, reduces seismic bearing capacity, and poses safety hazards. Furthermore, existing side-mounted bases and steel profiles mostly engage with planar contact, lacking specific limiting structures. This makes them prone to lateral displacement under vibration loads, further affecting the stability of the support. To address these unique challenges in side-mounted scenarios, there is an urgent need to design a side-mounted seismic support structure with adjustable installation height and reliable limiting. Utility Model Content

[0004] To address the technical problems of existing side-mounted seismic bracing systems, such as the inability to fine-tune the installation height and the tendency for side-mounting to shift, this utility model provides a side-mounted seismic bracing structure with adjustable installation height. This allows for flexible adaptation of the steel profile installation height, stable and reliable side-mounting, and avoids the need for additional drilling operations.

[0005] To achieve the above objectives, this utility model provides a side-mounted structure for a seismic bracing with adjustable installation height, comprising a W-shaped steel, a side-mounted base, and a bolt assembly; wherein the W-shaped steel and the side-mounted base are detachably connected by the bolt assembly.

[0006] W-shaped steel includes a central web, inclined webs, flanges, and end connecting plates. The inclined webs are symmetrically arranged on both sides of the central web, and the flanges are symmetrically arranged on both sides of the central web, located on the side of the inclined webs away from the central web. The inclined webs are located between the flanges and the central web. The end connecting plates are fixed to the side of the flanges away from the inclined webs. To avoid stress concentration, there are arc transition sections between the central web and the inclined webs, between the inclined webs and the flanges, and between the flanges and the end connecting plates. Multiple pentagonal combination holes are opened on the central web, and these pentagonal combination holes are spaced apart along the length of the central web.

[0007] The side-mounted base includes a fine-tuning mounting plate, a fixed mounting plate, and an end bending plate. The fine-tuning mounting plate is vertically fixed to the fixed mounting plate to form an L-shaped base structure. The end face of the fine-tuning mounting plate away from the fixed mounting plate is in close contact with the outer wall of the flange of the W-shaped steel. The fine-tuning mounting plate is provided with a five-pointed star combination hole corresponding to the position of the five-pointed star combination hole of the central web plate to ensure that the bolt assembly can be connected. The fixed mounting plate is used to fix it to a vertical base such as a wall or column. It has mounting holes, which are round holes, to accommodate conventional fixings such as expansion bolts. The number of mounting plates is at least one, depending on the load-bearing requirements. The end bending plates are integrally formed at the upper and lower ends of the fine-tuning mounting plate. Each end bending plate includes two symmetrically arranged inclined surfaces, which contact and cooperate with the inclined web surface of the W-shaped steel to form a limit.

[0008] The pentagonal combination hole includes two side pentagonal holes and a serrated connecting hole; the serrated connecting hole is located between the two side pentagonal holes and partially overlaps with the two side pentagonal holes to form a continuous channel structure; the serrated connecting hole includes at least one set of symmetrically arranged V-shaped grooves with an included angle of 108°, which are adapted to the pentagonal part of the bolt assembly; the side pentagonal holes and any set of symmetrically arranged V-shaped grooves constitute a snap-fit ​​hole position, that is, the pentagonal combination hole has at least three snap-fit ​​hole positions, which can realize multi-position snap-fit ​​of the bolt assembly.

[0009] The bolt assembly includes a bolt and a nut; the bolt consists of a threaded shank, a pentagonal shank, and a threaded head that are coaxially fixed in sequence; the cross-section of the pentagonal shank is pentagonal in shape and its size is adapted to the snap-fit ​​hole position.

[0010] The pentagram part can be set to one or two.

[0011] When there is only one pentagonal part, the pentagonal part can be selectively engaged with the pentagonal combination hole of the central web plate or the pentagonal combination hole of the fine-tuning mounting plate, which is suitable for scenarios with low seismic resistance requirements. When there are two pentagonal parts, the two pentagonal parts are respectively engaged with the pentagonal combination holes on the central web plate and the pentagonal combination holes on the fine-tuning mounting plate to form a double-locking fixation, which is suitable for scenarios with high seismic resistance requirements.

[0012] In both of the above configurations, the diameter of the screw is smaller than the width of the narrowest part of the serrated connecting hole, allowing the screw to move freely along the length of the serrated connecting hole, providing space for height fine-tuning. After the screw passes through the five-pointed star combination hole of the central web of the W-shaped steel and the five-pointed star combination hole of the side-mounted base fine-tuning mounting plate in sequence, it is threadedly connected to the nut, and the two are fixed by tightening the nut.

[0013] Compared with existing technologies, this technical solution has at least one of the following advantages: Through the multi-clamping hole design of the five-pointed star combination hole, the installation height of the W-shaped steel can be flexibly adjusted according to the vertical base deviation without additional drilling, ensuring the overall bearing strength and seismic performance of the seismic bracing; reducing construction costs and time, and improving construction efficiency; the end bending plate and the inclined web plate cooperate to form a lateral limit, effectively preventing the lateral displacement of the W-shaped steel and improving stability under vibration load.
