Description

Technical Field

[0001] The present application relates to the technical field of wind and earthquake resistance of archways, and in particular to an earthquake and wind resistance system of steel-wood composite brackets for archways of antique buildings. Background Art

[0002] Ancient archways are categorized by material, including wooden and stone archways. Wooden archways, with their diverse forms, flexible layouts, and ornate shapes, are often imitated in modern architecture. However, due to the unique architectural characteristics of archways, regardless of the material used for the main beams and columns, the brackets and roofing components often utilize the same materials and construction methods as ancient archways, ensuring they achieve the desired archway image.

[0003] From a mechanical perspective, the upper part of an archway is subject to vertical loads from gravity and horizontal loads from wind and earthquakes. Traditional archway upper structures lack rigid connections between the roof and the main beams; instead, brackets rest on the main beams. This transfers the upper gravity load to the main beams. However, this structure cannot resist the overturning moment generated by these horizontal loads. Traditional archway structures employ diagonally tensioned hooks to convert the horizontal forces acting on the roof into tensile pressure, which is then transferred to the lower main beams.

[0004] Traditionally, the purlins and main beams are made of steel, with steel rings embedded in the wood. The purlins and main beams are connected to the roof via the steel rings, creating a stable triangular structure. Due to the material properties of wood, it shrinks over time, causing the connection between the steel and wood to gradually loosen. Furthermore, the shrinkage of the bracket wood increases the gaps between the components. Under the reciprocating force of the wind, the roof of the upper part of the archway will sway and vibrate, and this vibration will further loosen the steel-wood connection. Over time, the steel will pull out of the wood. The stable triangle will disintegrate, and the upper part of the archway will be at risk of overturning and falling. Summary of the Invention

[0005] In order to improve the firmness of archway brackets, the present application provides an earthquake-resistant and wind-resistant system for archway brackets made of steel and wood.

[0006] This application provides an earthquake-resistant and wind-resistant system for steel-wood composite brackets of antique archways, which adopts the following technical solutions:

[0007] The steel-wood composite bracket system for archways of antique buildings is installed on the brackets of the archway and includes steel columns and steel beams. The upper end of the steel column passes through the middle of the bracket and is fixedly connected to the steel beam. Both ends of the steel beam are connected to the center truss. The steel column passes through the large bracket, the center melon arch, the Hua arch, and the slow arch in sequence. The steel column is divided into sections with different outer diameters in the length direction. The outer diameter of the steel column located in the large bracket is the smallest, and the outer diameter of the steel column located in the slow arch is the largest.

[0008] By adopting this technical solution, the combination of steel columns and steel beams effectively enhances the structural strength of the bracket sets. The installation of steel columns can resist the overturning bending moment generated by horizontal loads. The steel columns penetrate key locations of the bracket sets and connect to the steel beams, not only improving the stability of the overall structure, but also ensuring a close fit with the wooden components by staggering steel columns with different outer diameters. This allows the steel columns to form a close fit with the sidewalls of the same wooden component in different directions, further ensuring structural stability and enhancing earthquake and wind resistance. Furthermore, this design retains the appearance of a period building, achieving a perfect combination of tradition and modern technology.

[0009] Optionally, a gap is left between the slow arch and the Hua arch, and the system also includes a connecting seat installed between the slow arch and the Hua arch, the upper end surface of the connecting seat is in contact with the lower surface of the slow arch, the lower end surface of the connecting seat is in contact with the upper surface of the Hua arch, and a connecting piece is connected between the connecting seat and the steel column.

[0010] By adopting this technical solution, a connector was added between the slow arch and the Hua arch, connected to the steel columns via connectors, further strengthening the bracket structure. This design effectively disperses wind and earthquake forces, reduces structural deformation, and improves overall stability. Furthermore, the seamless design of the connector and the wooden components enhances the structural integrity and aesthetics.

[0011] Optionally, the connecting member is a connecting rod, which passes through the connecting seat and the steel column and is plugged and fixed.

[0012] By adopting the above technical solution, using connecting rods as connectors and inserting and fixing the connection base and steel columns, the installation process is simplified and the reliability and flexibility of the connection are improved. This design can adapt to structural deformation to a certain extent, reduce stress concentration, and thus extend the service life of the structure.

[0013] Optionally, the connecting rod includes a first rod and a second rod, the end of the second rod is provided with a groove, the groove runs through the circumference of the second rod, the first rod is inserted into the groove, the inner circumferential side wall of the connecting seat is attached to the outer side wall of the steel column, the connecting seat is provided with a connecting hole, the inner circumferential side of the connecting seat is provided with a notch, the connecting hole and the notch are connected, when the first rod is inserted into the steel column, the steel column is cylindrical, and when the steel column rotates, the second rod rotates into the notch.

[0014] By adopting this technical solution, the connecting rod is divided into a first rod and a second rod, connected by a groove and plug-in method, which allows the connecting rod to automatically adjust its position when the steel column rotates, ensuring the stability of the connection. At the same time, the slot design in the connecting seat provides additional space for the connecting rod to move, allowing the first rod to enter the slot, preventing it from easily separating from the connecting seat and the steel column, further improving the adaptability and earthquake and wind resistance of the structure.

[0015] Optionally, the steel column is a hollow structure, an annular groove is provided on the outer circumference of the steel column, the annular groove is connected to the hollow interior of the steel column, and there is a filler in the annular groove.

[0016] By adopting this technical solution, the steel column adopts a hollow structure with an annular groove on the outer periphery, increasing the weight and rigidity of the structure. The filling in the annular groove can further improve the strength and stability of the steel column.

[0017] Optionally, a mounting column is connected to the top of the steel column, and the mounting column is fixedly connected to the steel beam.

[0018] By adopting this technical solution, mounting columns are added to the top of the steel columns and fixedly connected to the steel beams, enhancing the stability of the bracket top structure. This design can better withstand the upper load, reduce structural deformation, and improve overall safety.

[0019] Optionally, sliders are slidably installed on both sides of the mounting column, and the sliders are fixedly connected to the steel beam.

[0020] By adopting this technical solution, the mounting block slides onto the mounting post and is fixedly connected to the steel beam, achieving an adjustable connection between the steel beam and the mounting post. This design can accommodate slight errors in different installation conditions, ensuring a tight and stable connection.

[0021] Optionally, the surface where the slider and the steel beam are connected is a curved surface.

[0022] By adopting the above technical solution, the arc surface design of the slider also reduces the friction between the slider and the steel beam, limits the horizontal displacement of the steel beam, and extends the service life.

[0023] In summary, this application has at least one of the following beneficial effects:

[0024] 1. The combined design of steel columns, steel beams, and connecting seats significantly improves the structural stability of the archway brackets of the antique building and enhances its earthquake and wind resistance.

[0025] 2. The use of adjustable connection methods and special structural designs (such as groove insertion of connecting rods and ring groove filling of steel columns) enables the system to adapt to different installation conditions and external environmental changes, thereby improving overall adaptability and durability;

[0026] 3. While enhancing the structural performance, the appearance characteristics of the antique building are retained, achieving a perfect fusion of tradition and modern technology, and enhancing the cultural value and ornamental value of the building. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present invention discloses a steel-wood composite bracket system for archway arches in an antique building. In the prior art, wooden components of archway archway archway systems are prone to breakage or displacement at joints when encountering strong earthquakes or strong winds, thereby affecting the safety of the entire building.

[0035] Reference Figure 1 To this end, this application primarily employs the following technical solution: a steel-wood composite bracket system for an antique archway, including a seismic and wind-resistant system comprising steel columns 10 and steel beams 20. The upper end of the steel column 10, after passing through the middle of the bracket 30, is fixedly connected to the steel beam 20. Both ends of the steel beam 20 are connected to the center girder 35. The archway's columns are fitted with embedded components, such as steel plates (not shown). The steel columns 10 and embedded components are secured with bolts 21 or welded.

[0036] Reference Figure 2After the bracket 30 is installed, the steel column 10 passes through the large bracket 31, the central melon bracket 32, the Chinese arch 33, and the slow arch 34 in sequence. The steel column 10 is segmented along its length with different outer diameters. The perforations in adjacent wooden components have different sizes. The steel column 10 located within the large bracket 31 has the smallest outer diameter, while the steel column 10 located within the slow arch 34 has the largest outer diameter. A gap is left between the slow arch 34 and the Chinese arch 33. The system also includes a connector 40 installed between the slow arch 34 and the Chinese arch 33. The upper end surface of the connector 40 is tightly fitted with the lower surface of the slow arch 34, while the lower end surface of the connector 40 is fitted with the upper surface of the Chinese arch 33. The connector 40 and the steel column 10 are fixedly connected by connectors 50, thereby improving earthquake and wind resistance and increasing structural stability.

[0037] Specifically, the steel column 10 comprises several sections, each with a different outer diameter. The steel column 10 comprises a first section 11, a second section 12, and a third section 13. The first section 11 passes through the large bucket 31 and the central melon arch 32, with an outer diameter of 50 mm. The second section 12 passes through the central arch 33, with an outer diameter of 60 mm. The third section 13 passes through the slow arch 34 and extends outside the bucket arch 30, with an outer diameter of 70 mm. The steel column 10 can be made of either high-strength steel or medium-carbon steel, which has high tensile strength and is suitable for withstanding high tensile forces. The steel column 10 is cylindrical in shape. The first section 11 has a smaller outer diameter, ensuring easier passage through the large bucket 31 and facilitating connection to other components. The second section 12 has a larger outer diameter, effectively dispersing stress and ensuring structural stability. The third section 13 has the largest outer diameter, effectively handling high wind or seismic loads.

[0038] When the steel columns 10 and brackets 30 with different outer diameters are connected, when the side walls of the steel columns 10 in the longitudinal direction contact the inner side walls of the brackets 33, the end faces of the steel columns 10 in the radial direction contact the upper surfaces of the brackets 33, thereby forming a fitting relationship between the steel columns 10 and the side walls of the same wooden component in different directions, and further ensuring the stability of the structure.

[0039] Specifically, the steel beam 20 can be made of high-strength alloy steel or stainless steel. Both ends of the steel beam 20 are tightly connected to the center girder 35. The steel beam 20 and the steel column 10 are fixedly connected to form a T-shape, integrating the upper and lower structures and improving the overall structural stability.

[0040] Reference Figure 1 and Figure 2The top of the steel column 10 is fixedly connected to a mounting column 14. The mounting column 14 is a rectangular structure. Sliders 15 are slidably mounted on opposite sides of the mounting column 14. A slide bar 16 is fixedly connected to the outer wall of the mounting column 14. The slide bar 16 has a slide groove extending through the slide bar 15. The vertical cross-section of the slide bar 15 is a concave structure. The slide bar 15 is slidably connected through the slide groove and the slide bar 16. After the steel beam 20 and the center girder 35 are fixedly connected, the slide bar 15 is slid so that the end of the steel beam 20 near the mounting column 14 always has a good welding position, which facilitates the fixed welding of the steel beam 20 and the steel column 10 with the slide bar 15. The slide bar 15 is then fixedly welded to the mounting column 14.

[0041] Reference Figure 3 Furthermore, the side of the slider 15 facing away from the mounting column 14 is a curved surface, and the end where the steel beam 20 and the slider 15 are connected is also provided with a mutually fitting curved surface. After the steel beam 20 and the slider 15 are mounted together, the slider 15 is fixedly welded to the mounting column 14, or when the steel beam 20 is fixedly connected to the center girder 35, the slider 15 and the mounting column 14 are mutually restrained in the horizontal direction.

[0042] Reference Figure 2 Preferably, the end of the steel beam 20 away from the slider 15 is fixedly connected with a bolt 21. The bolt 21 passes through the centering girder 35 and is then threadedly connected with a nut 22. The centering girder 35 has a countersunk hole for accommodating the bolt 21 and nut 22. The combination of the nut 22 and the bolt 21 secures the steel beam 20 to the wooden centering girder 35. If the end of the steel beam 20 near the centering girder 35 does not fit completely with the centering girder 35, a wooden wedge can be used to strengthen the tightness between the steel beam 20 and the centering girder 35.

[0043] In this embodiment, the connector 40 is made of a high-strength alloy, or alternatively, a titanium alloy, which provides sufficient strength and toughness. The connector 40 is 20 mm thick and 80 mm wide, effectively dispersing stress. In the event of a strong earthquake or strong wind, it partially transfers external forces to other structural components, mitigating the impact on the slow arch 34.

[0044] Reference Figure 4 and Figure 5Specifically, the connecting member 50 is a connecting rod, including a first rod 51 and a second rod 52. A groove 521 is provided at the end of the second rod 52, and the groove 521 runs through the circumference of the second rod 52. The first rod 51 is inserted into the groove 521, and a connection relationship is formed between the first rod 51 and the second rod 52 by friction. This design allows the connecting rod to flexibly adjust the angle to adapt to different connection requirements. The inner side wall of the connecting seat 40 is close to the outer wall of the steel column 10, and is provided with a connecting hole 41. The inner side wall of the connecting seat 40 is provided with a notch 42, and the connecting hole 41 and the notch 42 are connected. The steel column 10 is provided with a slot for the first rod 51 to be inserted, and the slot is adapted to the first rod 51. After the connecting rod passes through the connecting seat 40 and the steel column 10 and is inserted through interference fit, one end of the first rod 51 is fixedly inserted into the steel column 10, and the other end of the first rod 51 is located at the connection point between the connecting hole 41 and the notch 42. When the steel column 10 rotates, the first rod 51 slides away from the second rod 52 and rotates into the notch 42. The width of the notch 42 is smaller than the width of the connecting hole 41, and the side wall of the first rod 51 and the upper and lower side walls of the notch 42 fit together. The advantage of this design is that it can effectively prevent the first rod 51 of the connecting rod from leaving the connecting seat 40. The second rod 52 also blocks the connecting hole 41 to ensure the strength of the connection. The first rod 51 is protected by the connecting seat 40, so that the connecting seat 40 and the steel column 10 can form a stable connection through the first rod 51, thereby improving the reliability of the system.

[0045] Multiple connecting rods are spaced apart along the circumference of the connecting base 40, with the connecting holes 41 corresponding to the connecting rods. The slots 42 can be arcuate, ensuring a one-to-one correspondence between the slots 42 and the connecting holes 41. The slots 42 can also be annular, arranged along the circumference of the connecting base 40. The slots 42 in this application are preferably annular. First, rotate the steel column 10 so that the first rod 51 enters the slot 42, and then securely weld the mounting column 14.

[0046] Reference Figure 5 Furthermore, the steel column 10 is a hollow structure, and an annular groove 17 is provided on the outer circumference of the first section 11, the second section 12 and the third section 13 of the steel column 10. The annular groove 17 and the hollow structure of the steel column 10 are connected by a through hole 18. There is a filler in the annular groove 17. Specifically, when the steel column 10 is installed in the bracket 30, a filler that can increase the friction between the steel column 10 and the bracket 30 is filled in the steel column 10, such as mortar, epoxy resin and other adhesive materials. Increasing the viscosity and friction between the steel column 10 and the bracket 30 further effectively prevents the bracket 30 wood from separating from the steel material after shrinkage.

[0047] It should be noted that brackets 30 come in various types, including angled and flat brackets. The connection method between the steel columns 10 and steel beams 20 is the same, or alternatively, other existing connection techniques can be employed, such as direct bolt and nut fastening. The connecting base 40 is primarily installed in the gap between adjacent wooden members, which can be formed by installing loose brackets. Therefore, a bracket 30 is not limited to just one connecting base 40. If the bracket 30 structure is complex, the number of connecting bases 40 can be appropriately increased to strengthen the connection between the steel columns 10 and the wooden members of the bracket 30, thereby improving wind and earthquake resistance.

[0048] The implementation principle of this embodiment is as follows: By inserting steel columns 10 through each layer of wooden components of the bracket arch 30 and providing a connecting seat 40 between the slow arch 34 and the vertical arch 33, the structural integrity and stability are ensured. By arranging steel columns 10 of varying outer diameters in sections, the system's earthquake and wind resistance can be effectively improved while reducing material costs. Furthermore, the design of the connecting seat 40 and connecting rods enhances the connection strength between the various components, enabling the entire system to effectively disperse stress under extreme conditions and ensure building safety.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
