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 of archways of antique buildings. Background Art

[0002] Ancient archways are divided into wooden archways, stone archways, etc. according to the materials used. Wooden archways have various forms, flexible layouts, and gorgeous shapes, and are often imitated in modern times. However, due to the shape characteristics of the archway, no matter what materials are used for the main beams and columns, the upper brackets and roof parts often use the same materials and methods as the ancient archways, which makes it easy to achieve the image requirements of the archway.

[0003] From a mechanical point of view, the upper part of the archway has vertical loads caused by gravity and horizontal loads caused by wind and earthquake. In the traditional archway upper structure, there is no rigid connection between the roof and the main beam, and only the brackets are located on the main beam. The upper gravity load is thus transmitted to the main beam. The overturning moment caused by the horizontal load cannot be resisted by this structure. The traditional archway method is to set up a diagonal hook to convert the horizontal force acting on the roof into the tensile pressure of the hook and transmit it to the lower main beam.

[0004] In traditional practice, the hook is a steel component, and the purlin and main beam are wooden components. The steel pull ring is embedded in the wooden component, and the hook connects the roof and the main beam through the steel pull ring to form a stable triangular structure. Due to the material characteristics of wood, it shrinks over time, causing the connection between steel and wood to gradually loosen, and the shrinkage of the bracket wood also increases the gap between the components. Under the reciprocating action of wind force, the roof of the upper part of the archway will sway and vibrate, and the vibration will aggravate the loosening of the steel-wood connection point. Over time, the steel parts will be pulled 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 steel-wood composite brackets of antique building archway.

[0006] This application provides an earthquake-resistant and wind-resistant system for steel-wood combined brackets of antique archways, which adopts the following technical solutions: The steel-wood composite bracket anti-seismic and wind-resistant system of the archway of an antique building is installed on the bracket of the archway, and includes a steel column and a steel beam. The upper end of the steel column after passing through the middle of the bracket is fixedly connected to the steel beam, and both ends of the steel beam are connected to the center girders. 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 steel column located in the large bracket has the smallest outer diameter, and the steel column located in the slow arch has the largest outer diameter.

[0007] By adopting the above technical solution, the structural strength of the bracket is effectively enhanced through the combination of steel columns and steel beams. The installation of steel columns can resist the overturning bending moment caused by horizontal loads. The steel columns run through the key positions of the brackets and are connected to the steel beams, which not only improves the stability of the overall structure, but also ensures a close fit with the wooden components by setting steel columns of different outer diameters in sections, so that the steel columns and the side walls of the same wooden component in different directions form a fitting relationship, which can further ensure the stability of the structure and enhance the earthquake and wind resistance. In addition, this design also retains the appearance of antique buildings and achieves a perfect combination of tradition and modern technology.

[0008] Optionally, a spacing 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 fitted with the lower surface of the slow arch, the lower end surface of the connecting seat is fitted with the upper surface of the Hua arch, and a connecting piece is connected between the connecting seat and the steel column.

[0009] By adopting the above technical solution, a connecting seat is added between the slow arch and the Hua arch, and connected to the steel column through a connecting piece, further strengthening the bracket structure. This design can effectively disperse wind or earthquake forces, reduce structural deformation, and improve overall stability. At the same time, the fitting design of the connecting seat and the wooden components also enhances the integrity and aesthetics of the structure.

[0010] Optionally, the connecting member is a connecting rod, which passes through the connecting seat and the steel column and is plugged and fixed.

[0011] By adopting the above technical solution, connecting rods are used as connectors, and the connection base and steel column are connected by plug-in fixing, which not only simplifies the installation process, but also improves the reliability and flexibility of the connection. This design can adapt to structural deformation to a certain extent, reduce stress concentration, and thus extend the service life of the structure.

[0012] 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.

[0013] By adopting the above technical solution, the connecting rod is divided into a first rod and a second rod, which are connected by grooves and plug-in methods, so that the connecting rod can automatically adjust its position when the steel column rotates to ensure the stability of the connection. At the same time, the slot design in the connecting seat provides additional activity space for the connecting rod, and the first rod can enter the slot, so that the first rod cannot easily detach from the connecting seat and the steel column, further improving the adaptability and earthquake and wind resistance of the structure.

[0014] Optionally, the steel column is a hollow structure, an annular groove is provided on the outer peripheral side 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.

[0015] By adopting the above technical solution, the steel column adopts a hollow structure and an annular groove is opened on the outer peripheral side, which increases the lightness and rigidity of the structure. The filler in the annular groove can further improve the strength and stability of the steel column.

[0016] Optionally, a mounting column is connected to the top of the steel column, and the mounting column is fixedly connected to the steel beam.

[0017] By adopting the above technical solution, an installation column is added on the top of the steel column and fixedly connected to the steel beam, which enhances the stability of the top structure of the bracket. This design can better withstand the upper load, reduce structural deformation, and improve overall safety.

[0018] Optionally, sliders are slidably installed on both opposite sides of the mounting column, and the sliders are fixedly connected to the steel beam.

[0019] By adopting the above technical solution, the installation slider is slid on the installation column and fixedly connected with the steel beam, so as to realize an adjustable connection between the steel beam and the installation column.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The embodiment of the present application discloses an earthquake-resistant and wind-resistant system of a steel-wood combined archway of an antique building. In the prior art, wooden components of the earthquake-resistant and wind-resistant system of an antique building archway are prone to breakage or displacement at the nodes when encountering a strong earthquake or strong wind, thereby affecting the safety performance of the entire building.

[0027] Reference Figure 1 To this end, the present application mainly adopts the following technical solutions: the steel-wood combined bracket arch anti-seismic and wind-resistant system of the antique building archway includes a steel column 10 and a steel beam 20. The upper end of the steel column 10 after passing through the middle of the bracket arch 30 is fixedly connected to the steel beam 20, and both ends of the steel beam 20 are connected to the center girder 35. The columns of the archway are installed with embedded parts such as steel plates (not shown in the figure), and the steel column 10 and the embedded parts are fixed by bolts 21 or welding.

[0028] Reference Figure 2After the bracket 30 is installed, the steel column 10 passes through the large bracket 31, the center melon bracket 32, the Chinese arch 33, and the slow arch 34 in sequence. The steel column 10 is divided into sections with different outer diameters in the length direction. The perforation sizes of two adjacent wooden components are different. The outer diameter of the steel column 10 located in the large bracket 31 is the smallest, and the outer diameter of the steel column 10 located in the slow arch 34 is the largest. There is a gap between the slow arch 34 and the Chinese arch 33. The system also includes a connecting seat 40 installed between the slow arch 34 and the Chinese arch 33. The upper end surface of the connecting seat 40 is tightly fitted with the lower surface of the slow arch 34, and the lower end surface of the connecting seat 40 is fitted with the upper surface of the Chinese arch 33. The connecting seat 40 and the steel column 10 are fixedly connected by a connecting piece 50, thereby improving the earthquake and wind resistance performance and increasing the structural stability.

[0029] Specifically, the steel column 10 includes several sections, and each section has a different outer diameter. The steel column 10 specifically includes a first section steel column 11, a second section steel column 12 and a third section steel column 13, wherein the first section steel column 11 passes through the large bucket 31 and the center melon arch 32, and has an outer diameter of 50 mm; the second section steel column 12 passes through the Hua arch 33, and has an outer diameter of 60 mm; the third section steel column 13 passes through the slow arch 34 and extends out of the bucket arch 30, and has an outer diameter of 70 mm. The material of the steel column 10 can be high-strength steel, or medium-carbon steel, which has high tensile strength and is suitable for bearing large tensile forces. The shape of the steel column 10 is cylindrical. The outer diameter of the first section steel column 11 is small, ensuring that it is easier to pass through the large bucket 31, and it is also convenient to connect with other components. The outer diameter of the second section steel column 12 is large, which can effectively disperse stress and ensure the stability of the structure. The outer diameter of the third section steel column 13 is the largest, which can effectively cope with large wind or earthquake loads.

[0030] When the steel columns 10 and brackets 30 with different outer diameters are connected, the side walls of the steel columns 10 in the length direction are in contact with the inner side walls of the brackets 33, and the end faces of the steel columns 10 in the radial direction are in contact with the upper surface 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, which can further ensure the stability of the structure.

[0031] 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, so that the upper structure and the lower structure form a whole, which improves the stability of the overall structure.

[0032] Reference Figure 1 and Figure 2The top of the steel column 10 is fixedly connected with a mounting column 14, which is a rectangular structure. Slide blocks 15 are slidably installed 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 block 15 is provided with a slide groove. The vertical section of the slide block 15 is a concave structure. The slide block 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 block 15 is slid so that the end of the steel beam 20 close to the mounting column 14 always has a good welding position, which is convenient for fixing and welding the steel beam 20 and the steel column 10 with the slide block 15, and the slide block 15 is fixedly welded to the mounting column 14.

[0033] Reference Figure 3 Furthermore, the side of the slider 15 facing away from the installation column 14 is an arc surface, and the end where the steel beam 20 and the slider 15 are connected is also provided with an arc surface that fits each other. After the steel beam 20 and the slider 15 are installed in a fit with each other, the slider 15 is fixedly welded on the installation column 14, or when the steel beam 20 and the center girder 35 are fixedly connected, the slider 15 and the installation column 14 are mutually limited in the horizontal direction.

[0034] Reference Figure 2 Preferably, the end of the steel beam 20 away from the slider 15 is fixedly connected with a bolt 21, and the bolt 21 penetrates the centering girder 35 and is threadedly connected with a nut 22, and the centering girder 35 is provided with a countersunk hole for accommodating the bolt 21 and the nut 22. The cooperation between the nut 22 and the bolt 21 enables the steel beam 20 to be fixedly connected to the wooden centering girder 35. If the end of the steel beam 20 close to the centering girder 35 is not completely in contact 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.

[0035] In this embodiment, the connection seat 40 is made of high-strength alloy material, and can also be made of titanium alloy, which has certain strength and toughness. The thickness of the connection seat 40 is 20 mm, and the width is 80 mm, which can effectively disperse stress and transmit part of the external force to other structural parts when encountering a strong earthquake or strong wind, thereby reducing the impact on the slow arch 34.

[0036] 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 through friction. This design allows the connecting rod to flexibly adjust the angle to meet different connection requirements. The inner side wall of the connecting seat 40 is close to the outer side wall of the steel column 10, and a connecting hole 41 is provided. 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. When the connecting rod passes through the connection seat 40 and the steel column 10, one end of the first rod 51 is fixedly connected to the steel column 10, and the other end of the first rod 51 is located at the connection point between the connection 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 connection hole 41, and the side wall of the first rod 51 and the upper and lower side walls of the notch 42 fit each other. The advantage of this design is that it can effectively prevent the first rod 51 of the connecting rod from leaving the connection seat 40, and the second rod 52 also blocks the connection hole 41 to ensure the connection strength. The first rod 51 is protected by the connection seat 40, so that the connection seat 40 and the steel column 10 can form a stable connection through the first rod 51, thereby improving the reliability of the system.

[0037] A plurality of connecting rods are arranged at intervals along the circumference of the connecting seat 40, and the connecting holes 41 correspond to the connecting rods one by one. The notch 42 can be an arc groove, so that the notch 42 and the connecting hole 41 correspond to each other. The notch 42 can also be an annular groove, which is arranged along the circumference of the connecting seat 40. The notch 42 of the present application is preferably an annular groove. First, the steel column 10 is rotated to make the first rod 51 enter the notch 42, and then the mounting column 14 is fixed and welded.

[0038] 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, and the annular groove 17 and the hollow structure of the steel column 10 are connected through 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, such as mortar, epoxy resin and other adhesive materials, is filled in the steel column 10. The viscosity and friction between the steel column 10 and the bracket 30 are increased, and the separation of the bracket 30 wood from the steel material after shrinkage is further effectively prevented.

[0039] It should be noted that the brackets 30 are of the same type as the angle brackets and the flat brackets. The connection methods of the steel columns 10 and the steel beams 20 are the same, or other existing technologies are used for connection, such as directly fixing with bolts and nuts. The connection seat 40 is mainly installed in the spacing between two adjacent wooden components. The spacing between two adjacent wooden components can be formed by installing loose brackets. Therefore, one bracket 30 is not limited to one connection seat 40. If the bracket 30 has a complex structure, the number of connection seats 40 can be appropriately increased, thereby increasing the connection relationship between the steel column 10 and the wooden components of the bracket 30, and improving the wind and earthquake resistance.

[0040] The implementation principle of this embodiment is as follows: the present application ensures the integrity and stability of the structure by passing the steel column 10 through each layer of wooden components of the bracket 30 and setting a connecting seat 40 between the slow arch 34 and the Chinese arch 33. By setting steel columns 10 of different outer diameters in sections, the earthquake and wind resistance of the system can be effectively improved while reducing material costs. In addition, through the design of the connecting seat 40 and the connecting rod, the connection strength between the components is enhanced, so that the entire system can effectively disperse stress under extreme conditions to ensure building safety.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
