Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, and in particular to a bracket set structure. Background Technology
[0002] Dou-gong, also known as dou-gong, is a unique structure in Chinese architecture. It consists of layers of arch-shaped load-bearing structures that extend from the top of columns, between lintels and eaves purlins, or between frames. The square wooden blocks placed between the arches are called dou, and together they are called dou-gong.
[0003] A search revealed that patent publication number CN 219992698 U discloses a building bracket structure, including a supporting column body and mutually perpendicularly arranged arch bodies. One of the arch bodies has a central bracket in the middle. The top of the supporting column body has a seat bracket structure, and the mutually perpendicularly arranged arch bodies are located above the seat bracket structure. The mutually perpendicularly arranged arch bodies are arranged above the central bracket, and the arch bodies and the central bracket are arranged alternately from low to high. The seat bracket structure includes a seat bracket body. The top of the seat bracket body has an alternately arranged groove in the middle, and the bottom of the seat bracket body has side blocks on all four edges. The bottom of the seat bracket body also has a wedge groove. The supporting column body has a wedge block inside, and the wedge block matches the wedge groove.
[0004] Dougong (bracket sets) primarily serve to increase support, increase the compression surface, provide rain protection, resist earthquakes, and decorate. In traditional dougong structures, the components are connected by mortise and tenon joints. The connection between components is not rigid but rather a concave-convex joint on two wooden components, where the tenon and mortise engage to achieve the connection. However, the mortise and tenon joint method also has limitations. When subjected to strong seismic waves, the spatial structure of the mortise and tenon joint is prone to excessive misalignment when it "loosens" and is difficult to reset. In some cases, the mortise may even split and fall off, causing the structure to eventually lose its load-bearing capacity and collapse.
[0005] Therefore, it is necessary to provide a new dougong structure to solve the above-mentioned technical problems. Utility Model Content
[0006] The technical problem solved by this utility model is to provide a dougong structure that solves the problem of misalignment caused by the mortise and tenon joint connection method in traditional dougong structures and improves the seismic resistance of dougong structures.
[0007] To solve the above-mentioned technical problems, the dougong structure provided by this utility model includes: a column; a seated dougong structure, which is installed on the top of the column, the seated dougong structure including a base block, a turntable and a locking block, the base block being installed on the top of the column, the turntable being rotatably connected to the top surface of the base block, and the locking block being rotatably connected to the top surface of the turntable; an arch, which is horizontally supported inside the top surface of the locking block; a cantilever, which is vertically supported on the top surface of the arch; and a connecting structure, which is fixed at the center position of the upper and lower end faces of the turntable.
[0008] Preferably, the seat structure further includes a slot and a limiting ring, the slot being located on the top surface of the card block, and the limiting ring being fixed to the upper and lower end faces of the turntable.
[0009] Preferably, the top center of the card block has a cross-shaped slot arranged in an alternating pattern, and the arch engages with the column through the slot at the top of the card block.
[0010] Preferably, the turntable is rotatably connected to the card block and the bottom block respectively through the limiting rings fixed at its upper and lower end faces, and the side wall of the turntable is provided with round holes, which are evenly distributed on the side wall of the turntable.
[0011] Preferably, the connecting structure further includes a support rod, a screw cylinder, a limiting block, and a limiting groove. The support rod is fixed at the center of the upper and lower end faces of the turntable, the screw cylinder is slidably connected to the side wall of the support rod, the limiting block is fixed to the side wall of the support rod, and the limiting groove is located inside the screw cylinder.

[0014] Compared with related technologies, the bracket structure provided by this utility model has the following beneficial effects:
[0015] This utility model provides a bracket structure. First, the bracket structure is installed at the top of the column. By inserting a tool into the circular hole on the side wall of the bracket structure, the turntable in the bracket structure can be driven to rotate. The connecting structure will then rotate internally within the bracket structure, allowing the connecting structure to extend from its upper and lower end faces. The unthreaded ends of the connecting structure extend outwards and engage with the threaded holes at the top of the column, initially restricting the position of the bracket structure. Then, the arch is horizontally mounted on the top of the bracket structure, with the threaded holes at its upper and lower ends corresponding to the positions of the connecting structure, thus engaging the arch with the column. At the top of the bracket set, the turntable is rotated, which drives the connecting structure to be threadedly connected to the column and the arch respectively. The bracket set strengthens the connection between the arch and the column. Then, the bracket set is installed on the corresponding position on the surface of the arch. The eaves are longitudinally connected to the arch by the bracket set through a cross-locking mechanism. By rotating the turntable, the arch and the eaves are fixed together by the bracket set, which strengthens the connection between the arch and the eaves and enhances the stability of the overall structure, preventing misalignment. This structure has the advantage of solving the problem of misalignment caused by the mortise and tenon joint connection method of traditional bracket sets and improving the seismic resistance of the bracket set structure.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 , Figure 1 A schematic diagram of a preferred embodiment of the bracket structure provided by this utility model; Figure 2 for Figure 1 The diagram shows a three-dimensional representation of the seat's structure. Figure 3 for Figure 2 The diagram shows a fixed connection structure. Figure 4 for Figure 1 The diagram shows the structural connection of the seat bucket; Figure 5 for Figure 4 The enlarged structural diagram of part A is shown below; the bracket structure includes: a column 1; a base structure 2, which is installed on the top of the column 1, the base structure 2 including a base block 21, a turntable 22 and a locking block 23, the base block 21 being installed on the top of the column 1, the turntable 22 being rotatably connected to the top surface of the base block 21, and the locking block 23 being rotatably connected to the top surface of the turntable 22; an arch 3, which is horizontally supported inside the top surface of the locking block 23; a cantilever 4, which is vertically supported on the top surface of the arch 3; and a connecting structure 5, which is fixed at the center of the upper and lower end faces of the turntable 22.
[0024] In the specific implementation process, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the seat structure 2 also includes a slot 24 and a limiting ring 25. The slot 24 is provided on the top surface of the locking block 23, and the limiting ring 25 is fixed to the upper and lower end faces of the turntable 22. The top center of the locking block 23 is provided with a cross-shaped slot 24 that is arranged in an alternating pattern, and the arch 3 is engaged with the column 1 through the slot 24 provided on the top of the locking block 23. The turntable 22 is rotatably connected to the locking block 23 and the bottom block 21 respectively through the limiting rings 25 fixed on the upper and lower end faces, and the side wall of the turntable 22 is provided with round holes, and the round holes are evenly distributed on the side wall of the turntable 22.
[0025] The slot 24 on the top surface of the card block 23 allows the arch 3 to be engaged and its position to be restricted, so that the arch 3 is mounted on the top of the column 1. The turntable 22 can be driven to rotate by inserting a tool into the round hole on the side wall of the turntable 22.
[0026] In the specific implementation process, such as Figure 3 , Figure 4 and Figure 5As shown, the connecting structure 5 further includes a support rod 51, a screw cylinder 52, a limiting block 53, and a limiting groove 54. The support rod 51 is fixed to the center positions of the upper and lower end faces of the turntable 22, the screw cylinder 52 is slidably connected to the side wall of the support rod 51, the limiting block 53 is fixed to the side wall of the support rod 51, and the limiting groove 54 is located inside the screw cylinder 52. The top end of the screw cylinder 52 is closed, and the side wall of the screw cylinder 52 is threaded, while the top end of the screw cylinder 52 is not threaded. The screw cylinders 52 installed at the upper and lower ends of the turntable 22 are threadedly connected to the bottom block 21 and the locking block 23, respectively. The limiting block 53 is engaged inside the limiting groove 54, and the screw cylinder 52 is slidably connected to the support rod 51 by the limitation of the limiting groove 54 and the limiting block 53.
[0027] When the turntable 22 rotates, it can drive the support rod 51 to rotate, and then drive the screw cylinder 52 to rotate, so that the screw cylinder 52 at the upper and lower ends is threadedly connected to the locking block 23 and the bottom block 21 respectively, so that the screw cylinder 52 extends outward and is threadedly connected to the arch 3 and the column 1 respectively, thereby strengthening the connection between the arch 3 and the column 1, and also strengthening the connection between the arch 3 and the rocker arm 4.
[0028] The working principle of the bracket structure provided by this utility model is as follows:
[0029] When restoring or constructing ancient buildings, the first step is to fix the column 1. A screw cylinder 52 is installed at the top of the column 1. A tool is inserted into the through hole on the side wall of the turntable 22, and the turntable 22 is rotated. This causes the unthreaded portion of the screw cylinder 52 to extend from the top surface of the locking block 23 and the bottom surface of the bottom block 21, respectively. This allows one end of the lower screw cylinder 52 to initially engage with the screw hole at the top of the column, enabling the bottom block 21 to be initially positioned at the top of the column by the screw cylinder 52. Then, an arch 3 is horizontally mounted at the top of the locking block 23, engaging with the slot 24. Simultaneously, the top end of the upper screw cylinder 52 engages with the screw hole inside the arch 3. Rotating the turntable 22 further drives the screw cylinders 52 at both ends to rotate outwards. The screw cylinder 52 is threaded to the column 1 and the arch 3 respectively, making the connection between the column and the base block 21 more stable, and the connection between the arch 3 and the locking block 23 more stable. Then, a seat bracket is installed at the corresponding position on the surface of the arch 3. In the same way, one end of the screw cylinder 52 is first inserted to initially restrict its position. Then, the wedge 4 is mounted on the locking block 23 at its top, so that the wedge 4 and the arch 3 are installed in a cross shape. Then, the turntable 22 is rotated, so that the screw cylinders 52 at the upper and lower ends are threaded to the wedge 4 and the arch 3 respectively, which strengthens the connection between the wedge 4 and the arch 3, thereby restricting the position of the wedge 4 and the arch 3 and strengthening the overall stability. This structure has the advantages of solving the problem of misalignment caused by the mortise and tenon joint connection method of the traditional bracket structure and improving the seismic resistance of the bracket structure.
[0030] Compared with related technologies, the bracket structure provided by this utility model has the following beneficial effects:
[0031] This utility model provides a bracket structure. First, the bracket structure 2 is installed at the top of the column 1. By inserting a tool into the round hole on the side wall of the bracket structure 2, the turntable 22 in the bracket structure 2 can be driven to rotate. The connecting structure 5 will then rotate internally within the bracket structure 2, allowing the connecting structure 5 to extend from its upper and lower end faces. The unthreaded ends of the connecting structure 5 extend outwards and engage with the screw holes at the top of the column 1, initially restricting the position of the bracket structure 2. Then, the arch 3 is horizontally mounted on the top of the bracket structure 2, with the screw holes at its upper and lower ends corresponding to the positions of the connecting structure 5, so that the arch 3 engages with the bracket structure 2. The top of structure 2 is then rotated, which drives the connecting structure 5 to be threadedly connected to the column 1 and the arch 3 respectively. The connection between the arch 3 and the column 1 is strengthened by the bracket structure 2. The bracket structure 2 is then installed on the corresponding position on the surface of the arch 3. The eaves 4 are longitudinally connected to the arch 3 by the bracket structure 2 through a cross-locking mechanism. By rotating the turntable 22, the arch 3 and the eaves 4 are connected and fixed by the bracket structure 2, which strengthens the connection between the arch 3 and the eaves 4 and enhances the stability of the overall structure, preventing misalignment. This structure has the advantage of solving the problem of misalignment caused by the mortise and tenon joint connection method of traditional bracket structure and improving the seismic resistance of bracket structure.
