Description

Technical Field

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

[0002] In seismic design of buildings, seismic bracing is a key component to ensure the stability of pipelines and equipment during earthquakes. Currently, some seismic bracing systems on the market typically adopt an assembly mode of top-mounted base plus steel profile. That is, the top-mounted base is first manually fixed to the base such as concrete wall top, steel beam or purlin, and then the steel profile is connected to the top-mounted base with bolt assemblies. The bolt assemblies need to pass through the corresponding mounting holes pre-set on the top-mounted base and the steel profile for fixation.

[0003] However, in actual construction, factors such as deviations in installation position calculations and errors in on-site construction operations often necessitate fine-tuning of the installation height of the steel profiles to adapt to actual working conditions. While existing structures have multiple mounting holes on the steel profiles, these holes must be spaced far apart to ensure the overall structural strength of the steel profiles. This directly results in the inflexible adjustment of the steel profiles' installation position on the top mounting base, making it difficult to address construction errors.

[0004] When the above-mentioned installation deviation problems occur, construction workers often need to drill additional holes in the steel profile or top mounting base to complete the bolt connection. This operation not only increases construction costs and time, but also damages the original structural integrity of the steel profile, reduces its load-bearing strength and seismic performance, and poses safety hazards. Utility Model Content

[0005] In view of the technical problem in the existing seismic bracing top-mounted structure, where the mounting holes of the steel section and the top-mounted base are fixed and the installation height cannot be finely adjusted, resulting in additional drilling during construction, increased costs and affecting structural strength, this utility model provides a seismic bracing top-mounted structure with adjustable installation height, realizing flexible adjustment of the installation height of the steel section and avoiding additional drilling operations.

[0006] To achieve the above objectives, this utility model provides a seismic bracing top-mounted structure with adjustable installation height, including a W-shaped steel, a top-mounted base, a bolt assembly, and diagonal braces; wherein the W-shaped steel and the top-mounted base are detachably connected by the bolt assembly, and the diagonal braces are used to enhance the overall structural stability.

[0007] 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.

[0008] The top mounting base includes a vertical mounting plate, a horizontal mounting plate, and end bending plates. The vertical mounting plate is fixed vertically to the horizontal mounting plate to form an L-shaped base structure. The inner wall of the vertical mounting plate abuts against the outer wall of the flange of the W-shaped steel. The horizontal mounting plate has mounting holes for fixing the top mounting base to the base. These mounting holes are round and can accommodate conventional fasteners such as expansion bolts. The end bending plates are symmetrically fixed on both sides of the vertical mounting plate and bend towards the W-shaped steel. Two end connecting plates are located between the two end bending plates and abut against the inner wall of the end bending plates, forming a lateral limiting structure for the W-shaped steel. The vertical mounting plate has pentagonal combination holes corresponding to the positions of the pentagonal combination holes on the central web plate.

[0009] 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.

[0010] 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, and its size is adapted to the snap-fit ​​hole position; the diameter of the threaded shank is smaller than the width of the narrowest part of the serrated connecting hole, allowing the threaded shank to move along its length within the serrated connecting hole, providing space for fine adjustment of the installation height; after the threaded shank passes through the pentagonal combination hole in the central web plate and the pentagonal combination hole in the vertical mounting plate in sequence, it is threadedly connected to the nut to fix the W-shaped steel to the top mounting base.

[0011] The diagonal brace includes a vertical mounting part, an inclined connecting part, and a horizontal mounting part that are fixedly connected in sequence. The vertical mounting part and the horizontal mounting part are arranged perpendicularly, and the inclined connecting part is used to connect the vertical mounting part and the horizontal mounting part to form a triangular stable structure. Both the vertical mounting part and the horizontal mounting part are provided with pentagonal combination holes that are consistent with the pentagonal combination hole structure of the central web plate. The vertical mounting part is detachably connected to the central web plate of the W-shaped steel through a bolt assembly, and the horizontal mounting part is detachably connected to the base or other fixed structure through a bolt assembly.

[0012] Compared with existing technologies, this technical solution has at least one of the following advantages: Through the multi-clamping hole design of the pentagonal combination holes, the clamping position of the bolt's pentagonal part can be flexibly selected according to actual construction errors, allowing for fine-tuning of the W-shaped steel installation height without adjusting the top mounting base position, adapting to different working conditions; no additional drilling is required on the W-shaped steel or top mounting base, and fixing can be completed directly using the pre-set pentagonal combination holes, avoiding damage to the original structural integrity of the component and ensuring the overall load-bearing strength and seismic performance of the seismic bracing; it also reduces construction costs and time, and improves construction efficiency.
