Description

Technical Field

[0001] This invention relates to the field of dougong (bracket set) connection technology, specifically a dougong connection and fixing structure for imitation ancient buildings. Background Technology

[0002] Dou-gong, also known as dougong, douke, loulu, puzuo, etc., is a unique structural element in Chinese architecture. It consists of layers of arch-shaped load-bearing structures added to the top of columns, between lintels and eaves purlins, or between frames. The square wooden blocks placed between these arches are called dou, and together they form the dou-gong structure. Dou-gong is a supporting component that serves both a cantilever function and a decorative effect, formed by stacking and interlocking several dou-gong pieces. In modern antique-style architecture, dou-gong is more often used as a decorative technique. Prefabricated, integrated dou-gong saves on installation, but they require more space for placement and transportation. Therefore, spliced ​​dou-gong still exists in modern antique-style architecture.

[0003] CN221193750U discloses a connecting component for an antique-style dougong (bracket set) structure, comprising: a simulated dougong and a pressure block movably connected to the simulated dougong. The pressure block is used to cooperate with the top surface of the simulated dougong to form the inner wall of a mortise groove. An adjustment component is disposed on the simulated dougong, and the pressure block moves on the simulated dougong through the adjustment component. This utility model forms a variable mortise groove structure by cooperating with the top surface of the simulated dougong through the pressure block. During overall installation, the mortise groove is expanded to facilitate the insertion of tenons on the support beam. After installation, the adjustment component controls the movement of the pressure block, allowing the inner diameter of the mortise groove to be reduced, thereby locking the tenons on the external support beam to form a mortise and tenon connection in appearance. Compared with existing antique-style dougong structures, this solution further simplifies the overall installation method without affecting the antique artistic effect of the dougong.

[0004] In actual installation, the aforementioned patent controls the movement of the pressure block by adjusting the components located in the middle of the simulated bracket set, clamping the upper components to achieve the connection between the simulated bracket set and the upper components. However, this only achieves the connection between the two components. Connecting all components would require too many adjusting components. Since the bracket sets are perpendicularly intersecting, the pressure block of the topmost simulated bracket set can be adjusted flexibly, while the lower simulated bracket sets may not be able to achieve this movement flexibly. If the connection between the lower simulated bracket sets is fixed with bolts, vibration or other external forces during use may cause the connection to loosen, affecting the quality of the bracket set. After the bracket sets are assembled, the complete bracket set needs to be lifted. If the connection between the components is not stable, the components of the bracket set may move during the lifting process, and in severe cases, the bracket set may fall apart during the lifting process.

[0005] Therefore, the present invention provides a bracket connection and fixing structure for imitation ancient buildings to solve the above problems. Summary of the Invention

[0018] (1) The bracket connection and fixing structure for antique buildings described in this invention, through the mutual cooperation between the driving mechanism, the clamping mechanism and the connecting mechanism, when assembling the bracket, the components are placed in the correct position under the mutual cooperation of each component, and the worm gear on the component is rotated in sequence so that the adjacent components are locked together.

Therefore, when adjusting the distance between the clamping plates, the rotation amplitude of the second worm wheel can be avoided from being too small, which would cause the second locking block to be misaligned with the second locking groove. Under the restriction of the limiting block, the rotation amplitude of the second locking block can be avoided from being too large and overlapping with the second locking groove again.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example: Figures 1-10 As shown, the present invention discloses a bracket connection and fixing structure for antique-style buildings, comprising a base bracket 1, a first connecting arch 2, a second connecting arch 3, a third connecting arch 4, and a fourth connecting arch 5. The first connecting arch 2, the second connecting arch 3, the third connecting arch 4, and the fourth connecting arch 5 are sequentially interlocked and vertically arranged. A connecting mechanism 8 is provided within the first connecting arch 2 and the fourth connecting arch 5. A clamping mechanism 7 is provided within the first connecting arch 2, the second connecting arch 3, and the fourth connecting arch 5. The clamping mechanism 7 includes two sets of clamping plates 74. A driving mechanism 6 connects the clamping mechanism 7 and the connecting mechanism 8. The clamping mechanism 7 cooperates with the driving mechanism 6, which includes a worm gear 62. Both the clamping mechanism 7 and the connecting mechanism 8 are connected to the worm gear 62. In conjunction with the first connecting arch 2, the connecting mechanism 8 includes a second locking block 85 rotatably connected to the first connecting arch 2 and the fourth connecting arch 5; a clamping mechanism 7, which is assembled to engage with the component to be installed by adjusting the distance between each set of clamping plates 74, thereby clamping and fixing the component to be installed, making installation more convenient and reducing the possibility of damage to the component surface; the connecting mechanism 8 is assembled to operate synchronously with the clamping mechanism 7, and the second locking block 85 is engaged with adjacent components by rotating the second locking block 85, thereby making the connection between the components more stable; and a driving mechanism 6, which is assembled to drive the clamping plate 74 and the second locking block 85 to move by rotating the worm gear 62, so that the clamping mechanism 7 and the connecting mechanism 8 move simultaneously to achieve rapid installation.

[0035] In this embodiment, the components are stacked vertically and alternately in sequence. The first guide block 21 on the first connecting arch 2 is inserted into the limiting groove 11 of the seat 1, and the second locking block 85 at the bottom of the first connecting arch 2 is inserted into the second locking groove 81 of the seat 1. The second connecting arch 3 is placed on top of the first connecting arch 2, so that the second locking block 85 at the top of the first connecting arch 2 is inserted into the second locking groove 81 at the bottom of the second connecting arch 3. The worm gear 62 on the first connecting arch 2 is rotated, which drives the first worm wheel 63 and the second worm wheel 83 to rotate, so that the clamping plates 74 at both ends of the first connecting arch 2 move away from each other. The second locking block 85 remains stationary under the restriction of the limiting block 86, and only the second worm wheel 83 and the rotating shaft 84 rotate. Then, the third connecting arch 4 is placed on top of the second connecting arch 3 according to the position of the second guide block 31, and so on. Rotating the worm gear 62 on the first connecting arch 2 in the opposite direction causes the clamping plates 74 to move closer together. The second locking block 85 rotates with the rotating shaft 84, misaligning with the second locking groove 81 at the top of the seat bucket 1 and the second locking groove 81 at the bottom of the second connecting arch 3. At the same time, the first locking block 75 on the clamping plate 74 engages with the first locking groove 41 on the side wall of the third connecting arch 4, thus fixing the third connecting arch 4 to the first connecting arch 2, as well as fixing the first connecting arch 2 to the second connecting arch 3 and the seat bucket 1. The fourth connecting arch 5 is placed on the connecting bucket 42, and the second locking block 85 at its bottom is inserted into the second locking groove 81 on the connecting bucket 42. According to actual usage requirements, when installing components on the second connecting arch 3, rotating the worm gear 62 of the second connecting arch 3 causes the first locking block 75 to engage with the component to be installed, making installation quick and disassembly convenient.

[0036] like Figures 1-3 As shown, a set of limiting grooves 11 are provided on opposite sides of the seat 1. First guide blocks 21 are fixedly connected to both sides of the first connecting arch 2. The first guide blocks 21 are slidably connected to the limiting grooves 11. Second guide blocks 31 are fixedly connected to the top of the second connecting arch 3. The second guide blocks 31 are engaged with the bottom of the third connecting arch 4. Connecting buckets 42 are fixedly connected to the top of both ends of the third connecting arch 4. First slots 41 are provided on both sides of both ends of the third connecting arch 4. The seat 1, the first connecting arch 2, the second connecting arch 3, the third connecting arch 4, the fourth connecting arch 5, the clamping mechanism 7 and the connecting mechanism 8 are all made of aluminum alloy and their exposed surfaces are coated with plastic modified asphalt.

[0037] In this embodiment, when the first connecting arch 2 is placed on the seat 1, the first guide blocks 21 on both sides of the first connecting arch 2 first contact the limiting groove 11 to guide the first connecting arch 2 to be placed in the correct position. When the first connecting arch 2 and the seat 1 are fully engaged, the second locking block 85 at the bottom of the first connecting arch 2 is fully inserted into the connecting groove 82 of the seat 1. The third connecting arch 4 is placed in the correct position according to the position of the second guide block 31 at the top of the second connecting arch 3. When fixing the third connecting arch 4, the worm gear 62 of the first connecting arch 2 is rotated so that the clamping mechanism 7 on the first connecting arch 2 will hold the first connecting arch 2 in place. The three connecting arches 4 engage and clamp, simultaneously fixing the first connecting arch 2 to the seat 1 and the second connecting arch 3 respectively. During installation, the fourth connecting arch 5's corresponding connecting mechanism 8 engages with the third connecting arch 4 to achieve fixation. Adjusting the worm gear 62 on the fourth connecting arch 5 allows the first locking block 75 on the fourth connecting arch 5 to engage with the slot pre-cut on the building beam, thus completing the connection between the bracket and the building. When the bracket is used outdoors or in a humid environment, the aluminum alloy material is lightweight, durable, and requires no maintenance. The plastic modified asphalt on its structural surface further provides waterproofing and corrosion resistance.

[0038] like Figures 3-6 As shown, the driving mechanism 6 within the first connecting arch 2 also includes a cavity 61 formed inside the first connecting arch 2. A worm gear 62 is located within the cavity 61 and is rotatably connected to the side wall of the first connecting arch 2. First worm wheels 63 are respectively provided at the top of both ends of the worm gear 62, and the first worm wheels 63 cooperate with the worm gear 62. The worm gear 62 is provided with a first helical tooth 621 and a second helical tooth 622. The first helical tooth 621 is located in the middle of the worm gear 62, and the second helical teeth 622 are located at both ends of the worm gear 62. The pitch of the first helical tooth 621 is the same as the pitch of the second helical tooth 622. The clamping mechanism 7 within the first connecting arch 2 also includes a bidirectional threaded rod 71 fixedly connected to the first worm wheel 63. 1. Both ends are rotatably connected to the sidewalls of the cavity 61. The first worm gear 63 is located in the middle of the bidirectional threaded rod 71. Connecting plates 72 are respectively provided on both sides of the first worm gear 63. The connecting plates 72 are threadedly connected to the bidirectional threaded rod 71. Slide grooves 73 are opened on both sides of the first connecting arch 2. The end of the connecting plate 72 away from the first worm gear 63 passes through the slide groove 73 and is fixedly connected to the clamping plate 74. The first clamping block 75 is fixedly connected to the opposite side of the two clamping plates 74. The first slot 41 cooperates with the first clamping block 75. The structure and installation method of the driving mechanism 6 and the clamping mechanism 7 in the second connecting arch 3 and the fourth connecting arch 5 are the same as those in the first connecting arch 2.

[0039] In this embodiment, one end of the worm 62 passes through the cavity 61, and this end of the worm 62 is provided with teeth. When it is necessary to rotate the worm 62, a tool is used to engage with the end of the worm 62 to rotate the worm 62. The first worm wheel 63 meshes with the second helical tooth 622, and the second worm wheel 83 meshes with the first helical tooth 621. When the worm 62 rotates, it drives the first worm wheel 63 to rotate, causing the bidirectional threaded rod 71, which is fixedly connected to the first worm wheel 63, to rotate, thereby causing the threaded rod 71 to rotate. The two connecting plates 72 move relative to each other simultaneously, either moving closer or further away. When installing the upper component, the clamping plates 74 are first controlled to move away from each other. After the upper component is placed, the clamping plates 74 are then controlled to move closer to each other, so that the first locking blocks 75 on the clamping plates 74 on both sides of the component engage with the first locking slot 41 of the upper component, thus achieving connection and fixation. The first locking block 75 is set as a trapezoidal platform, and the end face connected with the clamping plate 74 is relatively large, which can be used to fit the first locking slot 41 with different sizes, making the connection tighter.

[0040] like Figures 3-10 As shown, the connecting mechanism 8 within the first connecting arch 2 also includes a second worm gear 83 located within the cavity 61 of the first connecting arch 2. The second worm gear 83 engages with the first helical gear 621. A rotating shaft 84 is fixedly connected to the second worm gear 83. The rotating shaft 84 is perpendicular to the worm 62 and its two ends rotatably penetrate the side wall of the first connecting arch 2. The rotating shaft 84 is perpendicular to the bidirectional threaded rod 71. A second locking block 85 is rotatably connected to both ends of the rotating shaft 84. The diameter of the second worm gear 83 is smaller than the diameter of the first worm gear 63. The top of the seat 1, the bottom of the second connecting arch 3, and the third connecting arch 83 are also included. The top of the connecting buckets 42 at both ends of the connecting arch 4 is provided with a second slot 81. The opening of the second slot 81 is adapted to the second block 85. A connecting groove 82 is provided on the side of the second slot 81 away from the opening. The connecting groove 82 communicates with the second slot 81. A set of limiting blocks 86 is fixedly connected on the side of the connecting groove 82 away from the second slot 81. The limiting blocks 86 cooperate with the second block 85. The upper end of the rotating shaft 84 of the connecting mechanism 8 in the fourth connecting arch 5 is rotatably connected to the inner wall of the fourth connecting arch 5, and the second block 85 is rotatably connected only at the lower end of the rotating shaft 84.

[0041] In this embodiment, while the first worm gear 63 is driven to rotate by the worm 62, the second worm gear 83 rotates simultaneously. Since the diameter of the second worm gear 83 is smaller than that of the first worm gear 63, the rotational speed of the second worm gear 83 is faster than that of the first worm gear 63 when the pitch is the same. When the first connecting arch 2 and the second connecting arch 3 are placed, the two second locking blocks 85 of the first connecting arch 2 respectively enter the connecting grooves 82 of the seat 1 and the second connecting arch 3. At this time, when the worm 62 of the first connecting arch 2 is rotated to control the clamping plate 74 to move away from each other, the two second locking blocks 85 cannot rotate under the restriction of the limiting block 86. There are two limiting blocks 86 in the connecting groove 82. One of the limiting blocks 86 is in contact with the second locking block 85 when the second locking block 85 enters the connecting groove 82. The other limiting block 86 is in contact with the second locking block 85. 6 is located between the two ends of the second locking block 85. One end of the second locking block 85 is located between the two limiting blocks 86. When the clamping plates 74 move away from each other, the second locking block 85 cannot rotate with the rotating shaft 84 under the action of the limiting block 86 that is in contact with it. When the worm gear 62 rotates in the opposite direction, the second locking block 85 also rotates in the opposite direction until it abuts against the other limiting block 86. If the worm gear 62 continues to rotate at this time, the rotating shaft 84 continues to rotate, while the second locking block 85 stops rotating. The two limiting blocks 86 restrict the rotation range of the second locking block 85. At this time, the second locking block 85 and the second locking groove 81 are staggered to complete the locking. The connection between the rotating shaft 84 and the second locking block 85 can be adjusted according to the actual situation. Two second locking blocks 85 can be connected, or one second locking block 85 can be connected.

[0042] Working principle: During installation, first, correctly place the first connecting arch 2 on the seat 1, and then place the second connecting arch 3 on the first connecting arch 2. At this time, the two second locking blocks 85 on the first connecting arch 2 are inserted into the connecting grooves 82 of the seat 1 and the second connecting arch 3, respectively. Rotate the worm gear 62 of the first connecting arch 2 to control the clamping plates 74 of the first connecting arch 2 to move away from each other. At this time, the second locking blocks 85 cannot rotate due to the obstruction of the limit block 86 and remain in the overlapping state with the second locking groove 81. Then, place the third connecting arch 4 on the second connecting arch 3, and rotate the worm gear 62 on the first connecting arch 2 in the opposite direction to bring the clamping plates 74 closer together. The first locking block 75 engages with the first locking groove 41 on the third connecting arch 4. Until the clamping plate 74 can no longer approach, the connection and fixation between the third connecting arch 4 and the first connecting arch 2 are completed. At the same time, the worm gear 62 also drives the second worm wheel 83 to rotate. The second worm wheel 83 rotates faster than the first worm wheel 63, so that the second locking block 85 can rotate more within the limitation range of the two limiting blocks 86, so as to ensure that the second locking block 85 and the second locking groove 81 are misaligned, and the connection between the components is tighter, thus completing the connection and fixation between the first connecting arch 2 and the seat 1 and the second connecting arch 3. The connection between the fourth connecting arch 5 and the third connecting arch 4 is the same. Rotate the worm gear 62 on the fourth connecting arch 5 so that the second locking block 85 engages with the third connecting arch 4, thus completing the connection and fixation.
