Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically a steel structure support frame for an underground parking garage. Background Technology

[0002] Steel structure support frames are commonly used components in construction. During construction, workers need to assemble steel structure support frames of different specifications according to the construction tasks to facilitate subsequent construction. Currently, in the construction of steel structures in underground parking garages, steel structure support frames are mostly fixed by welding or bolts, which has obvious defects:

[0003] Low assembly efficiency: The steel structure support frame requires different construction tasks and is assembled by workers on-site welding and bolt tightening, which takes a long time in actual assembly.

[0004] Insufficient expandability: During use, the steel structure support frame lacks standardized connection interfaces between adjacent steel structure support frames, requiring customized connectors for connection, which makes modular expansion during construction difficult;

[0005] Weak structural stability: The connection nodes between the steel structure support beam and the end plate are prone to deformation due to stress concentration, and conventional rib plate layouts are difficult to optimize the load transfer path.

[0006] Therefore, there is an urgent need for a steel structure support frame that can be quickly assembled, easily expanded, and has the ability to strengthen and fine-tune nodes. Utility Model Content

[0007] This utility model addresses the problems existing in the prior art by providing a steel structure support frame for underground parking garages.

[0043] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0044] Example 1:

[0045] like Figure 1-4 As shown, the core internal structure of the steel structure support frame consists of a lower support column 1, a main support beam 3, and an end plate 4. Two H-beam main support beams 3 are arranged in parallel, with horizontal I-beam lower support columns 1 welded to the bottom, forming an inverted T-shaped load-bearing base. Reinforcing ribs 2 are symmetrically fixed on the outer side of the web of the main support beam 3, with the apex of the ribs vertically aligned with the center line of the lower support column 1, so that the vertical load is directly transferred to the support column.

[0046] The upper end plate 4 is a thick rectangular steel plate. The edge of the end plate 4 is provided with a tenon and mortise locking block 103 and a lower positioning shaft hole 104. At the same time, the upper part of the main support beam 3 is provided with a matching inner groove 201, which is matched with the tenon and mortise locking block 103.

[0047] The main assembly process for the main support beam 3 and the end plate 4 is as follows:

[0048] 1. Insert the tenon and mortise locking block 103 of the end plate 4 into the inner groove 201 of the main support beam 3;

[0049] 2. Insert the mating pin 202 through the through hole of both, and install a mating sleeve 203 on the top to prevent it from falling off;

[0050] 3. Tighten the adjusting bolt 204 on the outside of the inner groove 201 so that it pushes into the lower positioning shaft hole 104, thereby achieving horizontal fine adjustment.

[0051] Furthermore, the steel structure support frame is equipped with a modular expansion structure, which enables tool-free rapid splicing of adjacent support frames through assembly and connection components 5, improving overall expansion efficiency. The specific operation steps are as follows:

[0052] Align the right connecting component 5-2 of the support frame with the left connecting component 5-1 of the B support frame, rotate the adjusting knob 302 to drive the connecting threaded rod 304 into the fixing sleeve 403 until the fixing flange 303 is tightly against the surface of the end plate 4, thus completing the assembly work.

[0053] Furthermore, the end plate 4 is provided with an expansion connection hole 102 and a positioning hole 101. The expansion connection hole 102 facilitates the insertion of an additional support rod at the center of the steel structure support frame, and the positioning hole 101 allows for the assembly of a transverse reinforcing beam from above via a threaded connection, thereby adapting to construction tasks under different conditions.

[0054] Example 2:

[0055] This steel structure support frame can be used in certain special construction scenarios to adapt to the overall strength requirements under different conditions. Regarding the position between the mating pin 202 and the mating sleeve 203, workers can add a damping rubber ring at the midpoint to improve the overall seismic resistance of the steel structure support frame.

[0056] Furthermore, during long-term use and subsequent maintenance, staff can remove the mating pin 202 and replace the mating sleeve 203 located above, thereby achieving rapid component replacement and improving maintenance efficiency.

[0057] Furthermore, for some large-span structures, workers need to further expand the connection aperture 102 to install prestressed cables. After the prestressed cables pass through the expanded connection aperture 102 of the adjacent support frame, they are tensioned to apply a reverse pre-tension force to the main support beam 3, thereby offsetting the mid-span sagging load and preventing cracking of the concrete top slab.

[0058] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0059] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0060] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.
