Description

Technical Field

[0001] This utility model belongs to the field of support frame technology, and specifically relates to an anti-seismic support frame. Background Technology

[0002] The support frame is the steel structural system that forms the main load-bearing skeleton of the canopy structure. It is the core structure of the entire canopy, responsible for supporting the roof covering material and resisting various external loads, safely transferring these loads to the foundation. The support frame includes columns, main beams, secondary beams, and diagonal braces.

[0003] In the existing technology, the supporting steel frame of the canopy structure built by the roadside is often easily disturbed by the vibration of passing vehicles, which causes the columns to tilt, resulting in the overall tilt of the support frame, affecting its stability and service life.

[0004] Furthermore, when existing traditional steel structure support frames are subjected to external vibrations, such as low-magnitude earthquakes, the strong vibration force can even cause the columns to shift, leading to the tilting of the main structure.

[0005] Meanwhile, existing building steel structure support frames often use a large number of fixed diagonal braces for support, which results in the support frame structure occupying a larger area than its actual area, leading to a large space occupation.

[0006] The large size of the tie rod makes it difficult to transport, the installation process requires multiple people and is quite complex, and its position is difficult to adjust after installation, which limits its applicability. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-seismic support frame.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an anti-seismic support frame, comprising a support body, the support body comprising a column and a base, both sides of the column being fixed with L-shaped fasteners by bolts, the end of the L-shaped fastener away from the column having a rectangular groove, the inner wall of the rectangular groove of the L-shaped fastener being fixed with U-shaped parts by bolts, one end of the U-shaped part being fixed with an L-shaped plate, and the inner wall of the L-shaped plate being fixed with reinforcing ribs.

[0009] Preferably, each of the reinforcing ribs has a flat end at its acute angle, and the flat end of the reinforcing rib makes both ends of the reinforcing rib flush with the L-shaped plate.

[0010] Preferably, a chamfered groove is provided at the right angle of the reinforcing rib, and the length of both sides of the chamfered groove is less than one-third of the length of both sides of the L-shaped plate.

[0011] Preferably, the base has a top groove, and a fixing platform is fixed at the center of the inner wall of the top groove, with the top of the fixing platform fixed to the bottom of the column.

[0012] Preferably, the top of the base has multiple oblique through slots.

[0013] Preferably, the top of the inclined channel is provided with a dense mesh, which is attached to and blocks the opening above the inclined channel.

[0014] Preferably, the base has a bottom groove, and the highest point of the inner wall of the bottom groove is greater than five centimeters.

[0015] Preferably, multiple baffles are linearly arrayed and fixed on the sides of the base, and the baffles are trapezoidal in shape.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses separate U-shaped and L-shaped fasteners, allowing workers to fix the L-shaped fasteners to appropriate positions on the column before installing the reinforcing ribs. Then, the U-shaped and L-shaped fasteners are fixed together with bolts, which facilitates operation and simplifies the process. After the support body has been used for a period of time, if the ground becomes compacted due to vibration of the column and continuous pressure from the L-shaped plate, or other changes in ground height such as weathering or soil erosion, workers can adjust the height of the L-shaped fasteners on the column. This ensures that the bottom of the L-shaped plate is always in close contact with the ground, providing better support and preventing the column from tilting, thus improving its service life and applicability. Furthermore, the L-shaped plate and reinforcing ribs provide support and prevent tipping through their own stable triangular mechanism. The combined size of the two is small and does not require external space, reducing space occupation.

[0018] 2. This utility model, by reserving a top groove, a bottom groove, and a fixing platform during the foundation pouring process, allows workers to fill soil into the foundation after the column is fixed to the fixing platform. The soil, after being filled and compacted, fills the top groove, thereby increasing the self-weight of the top groove and enabling the foundation to resist vibration by relying on the compacted soil. The compacted soil in the top groove can also help prevent the column from shifting. When the foundation is subjected to pressure during installation, the soil is squeezed into the bottom groove, further preventing the foundation from shifting due to vibration. Moreover, the soil at the foundation can rely on the top and bottom grooves as fulcrums to create shielding and restriction, weakening the impact of soil erosion, intercepting and blocking soil flow, and improving the stability of the column.

[0019] 3. This utility model uses a dense mesh to prevent soil from entering the inclined channel during compaction, and the inclined channel can drain rainwater when it rains. Whether the base is buried in the soil or placed on the ground, the inclined channel can drain rainwater that the soil cannot absorb in the top groove, and the dense mesh prevents the soil from leaving the top groove, further ensuring the compaction effect, thereby preventing the column from tilting or the base from shifting when subjected to vibration, and improving the seismic resistance.

[0036] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0038] Example:

[0039] refer to Figures 1-6 An anti-seismic support frame includes a support body 1, which includes a column 101 and a base 102. Both sides of the column 101 are fixed with L-shaped fasteners 203 by bolts. The end of the L-shaped fastener 203 away from the column 101 has a rectangular groove. The inner wall of the rectangular groove of the L-shaped fastener 203 is fixed with U-shaped parts 202 by bolts. One end of the U-shaped part 202 is fixed with an L-shaped plate 201. The inner wall of the L-shaped plate 201 is fixed with reinforcing ribs 2.

[0040] Specifically, the separate U-shaped component 202 and L-shaped fixing component 203 allow workers to fix the L-shaped fixing component 203 to appropriate positions on the column 101 before installing the reinforcing rib 2. Then, the U-shaped component 202 and the L-shaped fixing component 203 are secured with bolts. This facilitates operation and simplifies the process. Furthermore, after the support body 1 has been in use for a period of time, if the ground becomes compacted due to vibrations from the column 101 and continuous pressure from the L-shaped plate 201, or if other changes in ground height occur, such as weathering or soil erosion, workers can adjust the height of the L-shaped fixing component 203 on the column 101. This ensures that the bottom of the L-shaped plate 201 remains in close contact with the ground, providing better support and preventing the column 101 from tilting, thus extending its service life and applicability. The L-shaped plate 201 and the reinforcing rib 2 provide support and prevent tipping through their stable triangular mechanism. The combined size is small and does not require external space occupation, reducing space requirements.

[0041] Each of the acute angles of the reinforcing rib 2 is provided with a flat end 3, which makes both ends of the reinforcing rib 2 flush with the L-shaped plate 201. A chamfered groove 4 is provided at the right angle of the reinforcing rib 2, and the length of both sides of the chamfered groove 4 is less than one-third of the length of both sides of the L-shaped plate 201.

[0042] Specifically, by opening a flat end 3 on the reinforcing rib 2, the difficulty of processing sharp corner workpieces is prevented. The flat end 3 makes the reinforcing rib 2 without a sharp point, preventing the hot melt at the sharp point from being too small and easily melted, and can save materials and reduce production costs. The flat end 3 and the corner groove 4 allow the process to avoid sharp corners, thereby reducing the processing difficulty. Moreover, the heat will not be concentrated at the bending point during welding, thereby reducing the heat-affected zone.

[0043] The base 102 has a top groove 5, and a fixing platform 501 is fixed in the center of the inner wall of the top groove 5. The top of the fixing platform 501 is fixed to the bottom of the column 101. The base 102 has a bottom groove 6, and the highest point of the inner wall of the bottom groove 6 is greater than five centimeters.

[0044] Specifically, by pre-reserving a top groove 5, a bottom groove 6, and a fixing platform 501 during the pouring of the base 102, after the column 101 is fixed to the fixing platform 501, workers fill soil into the base 102. After the soil is filled and compacted, it fills the top groove 5, thereby increasing the self-weight of the top groove 5 and allowing the base 102 to resist vibration by relying on the compacted soil. The compacted soil in the top groove 5 can help prevent the column 101 from shifting. When the base 102 is subjected to pressure during installation, the soil is squeezed into the bottom groove 6, further preventing the base 102 from shifting due to vibration. Moreover, the soil at the base 102 can rely on the top groove 5 and the bottom groove 6 as fulcrums to create shielding and restriction, weaken the impact of soil erosion, intercept and block soil flow, and improve the stability of the column 101.

[0045] The base 102 has multiple oblique slots 7 on its top. The top of the oblique slots 7 is provided with a dense mesh 8, which is attached to and blocks the slot opening above the oblique slots 7.

[0046] Specifically, the dense mesh 8 makes it difficult for soil to enter the inclined channel 7 during compaction, and the inclined channel 7 can drain rainwater when it rains. Whether the base 102 is buried in the soil or placed on the ground, the inclined channel 7 can drain rainwater that the soil cannot absorb in the top groove 5, and the dense mesh 8 prevents the soil from leaving the top groove 5, further ensuring the compaction effect, thereby preventing the column 101 from tilting or the base 102 from shifting when subjected to vibration, and improving the seismic resistance.

[0047] Multiple baffles 9 are linearly arrayed and fixed on the sides of the base 102, and the baffles 9 are trapezoidal in shape.

[0048] Specifically, while providing support to the base 102, the baffle 9 increases the contact area between the base 102 and the soil when the base 102 is affected by vibration, thereby greatly increasing the soil's blocking effect, preventing the base 102 from slipping and causing the column 101 to tilt due to vibration, and improving the stability of the column 101.

[0049] The working principle of this utility model is as follows: During installation, the staff chooses to bury the base 102 into the foundation according to the actual situation, fix the platform 501 to support the column 101, fill the top groove 5 with soil and compact it, and the bottom groove 6 accommodates the squeezed soil to enhance the resistance to displacement.

[0050] Workers select appropriate heights on both sides of the column 101 and fix the L-shaped fastener 203 at appropriate heights with bolts, so that the bottom of the L-shaped plate 201 connected by the U-shaped part 202 is in close contact with the concrete. The reinforcing rib 2 provides triangular support by being flush with the L-shaped plate 201 through the flat end 3, and reduces processing complexity and production costs. When the column 101 is affected by vibration, the L-shaped plate 201 decomposes the horizontal impact force into vertical downward pressure. The baffle 9 increases the contact area between the base 102 and the soil to prevent slippage. During rainfall, the inclined channel 7 drains accumulated water, and the dense mesh 8 with a mesh size of less than 2mm intercepts backfill particles, maintaining the soil compaction of the top groove 5. The chamfered groove 4 reduces the welding thermal stress of the reinforcing rib 2.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
