Description

Technical Field

[0001] This utility model belongs to the field of ancient building model technology, specifically relating to a roof structure for an ancient building model. Background Technology

[0002] Ancient Chinese architecture was primarily constructed of wood. However, due to the nature of wood itself, it was less resistant to natural disasters and human-caused damage. Over the centuries, many ancient Chinese buildings have been damaged or even disappeared. Many buildings can only be understood through drawings and records. To cater to consumers who love ancient Chinese architecture, many ancient building models have appeared on the market. In the field of ancient building restoration, the restoration of ancient building models is also used as a technical verification for restoration.

[0003] During the restoration of ancient buildings, wooden structures often develop cracks due to long-term erosion from rainwater. Current restoration methods typically use screws for connection and fixation. However, this can cause wooden components to crack and break further due to the impact force generated during fixing. Furthermore, when using screws for connection, the screws connected between wooden components may come loose over time, meaning that the wooden component with the screw may detach from another wooden component, resulting in poor structural connectivity and instability.

[0004] Therefore, it is necessary to verify the model through a corresponding ancient building model. However, most existing ancient building models only focus on the appearance and make them into a one-piece structure, or fix the various parts directly with screws. Since the main body of the model is also made of wood, the use of screws or a one-piece structure cannot better demonstrate the mortise and tenon joint technology. Using screws will also make the model's components more susceptible to the impact force generated during fixing, which can easily break the wood components. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a roof structure for an ancient building model, so as to solve the problems that the existing ancient building model roof structure uses screws for connection, which makes the wooden structure easy to be damaged, the connection unstable, and is not conducive to structural verification.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A roof structure for an ancient building model includes a beam frame, ridge purlin, eaves board, rafters, and tiles. The beam frame is a pyramidal structure forming multiple side top surfaces on its perimeter. Several parallel and spaced rafters are arranged side by side on each side top surface. The ridge purlin is located at the top of the beam frame. Each side top surface has an eaves board along its outer edge. Both the ridge purlin and the eaves board have grooves for embedding the rafters. The ridge purlin, in conjunction with the eaves boards on at least two side top surfaces, presses the rafters on the corresponding side top surfaces onto the beam frame through the grooves. Tiles are staggered between adjacent rafters.

[0008] In one possible implementation, the groove on the ridge purlin is groove one, which is a groove structure, and the ridge purlin is connected to the wooden rafters on the side top surface facing the groove of groove one by groove one.

[0009] In one possible implementation, the ridge purlin has several pressure grooves on both sides in the width direction to press down on the wooden rafters on the corresponding side top surfaces.

[0010] In one possible implementation, the groove on the eaves board is groove two, which is a through groove structure, and the wooden rafter is embedded in groove two and passes through the eaves board.

[0011] In one possible implementation, the wooden rafters are connected and fixed to the beam frame by wooden tenon joints.

[0012] In possible implementations, a large scimitar is also included, which is connected to the ridge purlin and extends outward. The beam frame is provided with shrimp-whisker beams that support the large scimitar from both sides. The shrimp-whisker beams on both sides of the large scimitar are connected and fixed to the large scimitar through the same wooden tenon connector. The wooden tenon connector passes through both shrimp-whisker beams and the large scimitar.

[0013] In one possible implementation, the beam frame has four side top surfaces, including two main side top surfaces and two side side top surfaces that are opposite to each other. The ridge purlin, together with the eaves board on the two main side top surfaces, presses the wooden rafters on the corresponding side top surfaces onto the beam frame through a groove. The side side top surfaces are lower than the main side top surfaces and are longitudinally connected to the bottom of the main side top surfaces.

[0014] In one possible implementation, the pressure groove is a square groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The roof structure of this utility model for ancient buildings adopts a grooved and snap-fit ​​structure that is more compatible with the structure of ancient buildings. It can not only press down on one end of the ridge purlin from the rafters, but also fasten the other end of the rafters through the eaves board. In this way, the rafters can be held and fixed by fixing the ridge purlin and the eaves board, avoiding the problem of easily damaging wooden components when using screws for connection. It also has better connection stability. Furthermore, this pressing and fixing structure can facilitate the verification and repair of the design structure through the model, and can also improve the aesthetics of the model in terms of wooden structure.

[0017] Moreover, the ridge purlin with its grooved structure can simultaneously clamp and hold the wooden rafters on the front and rear top surfaces, improving the structural connectivity and making better use of the ridge purlin's stability.

[0018] At the same time, by connecting the shrimp-whisker beams and the large scissor beams with wooden tenons, the large scissor beams and the shrimp-whisker beams on both sides can be connected as one, which can also have better connection stability and avoid damage to the components.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] Please refer to Figure 1-4As shown, an embodiment of this application provides a roof structure for an ancient building model, including a beam frame 2, a ridge purlin 1, an eaves board 3, and wooden rafters 7 and tiles (not shown in the figure). The beam frame 2 has a pyramidal structure to form multiple side top surfaces on its perimeter. Several parallel and spaced wooden rafters 7 are arranged side by side on the side top surfaces. The ridge purlin 1 is located at the top of the beam frame 2. An eaves board 3 is provided on the outer edge of each side top surface. Both the ridge purlin 1 and the eaves board 3 have grooves for embedding the wooden rafters 7. The ridge purlin 1, in conjunction with the eaves board 3 on at least two side top surfaces, presses the wooden rafters 7 on the corresponding side top surfaces onto the beam frame 2 through the grooves. Tiles are staggered between two adjacent wooden rafters.

[0026] The beam frame 2 is the main supporting structure for the roof, supporting and bearing the ridge purlin 1, eaves board 3, rafters 7, and tiles. The beam frame 2 has a pyramidal structure, creating multiple side roof surfaces, commonly four, which is also the main structural form of ancient building roofs. Each side roof surface of the beam frame 2 is equipped with rafters 7 for installing several tiles. The rafters 7 are spaced apart and parallel, with tiles arranged in an alternating, overlapping pattern between them. This structure accurately recreates the roof structure of ancient buildings. Compared to existing roof models with simply carved tile structures, this roof structure is more realistic, better suited for display, and more conducive to design verification. The eaves board 3, used on the sides of the roof, seals the ends of the rafters 7, preventing rainwater and snowmelt from directly eroding the internal wooden components (such as rafters and purlins) and walls, thus preventing the wood from rotting due to moisture. The ridge purlin 1 bears the load at the top of the roof (such as roof tiles and ridge decorations) and transfers the weight to the beam frame 2. It is the base of the ridge and ensures the longitudinal stress of the roof is balanced. The fixing method of the rafters 7 is different from the existing structure that is fixed by screws. It is mainly fixed by the ridge purlin 1 and the eaves board 3 on at least two sides through the pressing groove. That is, both the ridge purlin 1 and the eaves board 3 are provided with pressing grooves for the rafters 7 to be inserted. The rafters 7 are inserted into the pressing grooves from bottom to top. This interlocking pressing method can effectively hold the rafters 7 and achieve basic fixation. This avoids the problem of damage to related wooden components caused by the screw connection method. It also has better disassembly performance and is more convenient and reliable.

[0027] Through the above technical solution, a grooved and snap-fit ​​structure that is more suitable for the structure of ancient buildings is adopted. This allows the ridge purlin 1 to be pressed down on one end of the wooden rafter 7, and the eaves board 3 to fasten the other end of the wooden rafter 7. In this way, the wooden rafter 7 can be pressed and fixed by fixing the ridge purlin 1 and the eaves board 3, avoiding the problem of easily damaging wooden components when using screws for connection. It also has better connection stability. Furthermore, this pressing and fixing structure can facilitate the verification of the design structure through the model for repair, and can also improve the aesthetics of the model on the wooden structure.

[0028] In one embodiment, the groove on the ridge purlin 1 is groove 11, which is a groove structure. The ridge purlin 1 is connected to the wooden rafter 7 on the side top surface facing the groove opening of groove 11 by groove 11.

[0029] In this way, the setting of the groove structure 11 can reduce the impact of the groove on the ridge purlin 1 structure, and at the same time can also achieve the pressing of the wooden rafters 7, making the structural design more reasonable.

[0030] Furthermore, in order to simultaneously press down the wooden rafters 7 on both the front and rear sides of the roof, the ridge purlin 1 is provided with several pressing grooves 11 on both sides in the width direction to press down the wooden rafters 7 on the corresponding side top surfaces respectively.

[0031] Since the wooden rafters 7 are relatively long and are positioned vertically relative to the eaves board 3, in the embodiments of this application, the groove on the eaves board 3 is groove 2 31, which is a through groove structure. The wooden rafters 7 are embedded in groove 2 31 and pass through the eaves board 3.

[0032] Through the through groove structure, the pressure groove 31 allows the wooden rafter 7 to be embedded and pass through, thus enabling a matching snap-fit ​​connection.

[0033] Due to the large number of roof tiles and the significant weight borne by the wooden rafters 7, to further improve their stability, the wooden rafters 7 are connected and fixed to the beam frame 2 via wooden tenon connectors 5. The wooden tenon connectors 5 act as akin to wooden nails, but their installation requires pre-drilling holes in the corresponding wooden components before inserting the tenon connectors 5 into the holes. Because the drilling process utilizes a rotational cutting force, it does not cause the wooden components to crack or further crack. Thus, the connection via wooden tenon connectors 5 not only provides good connection performance but also avoids damage to the wooden components, facilitating the restoration and verification of ancient buildings.

[0034] In the embodiments of this application, a large purlin 4 connected to the ridge purlin 1 and extending outward is also included. The beam frame 2 is provided with shrimp-whisker beams 6 supporting the large purlin 4 from both sides. The shrimp-whisker beams 6 on both sides of the large purlin 4 are connected and fixed to the large purlin 4 by the same wooden tenon connector 5. The wooden tenon connector 5 passes through both shrimp-whisker beams 6 and the large purlin 4.

[0035] The shrimp-whisker beam 6 and the large scissor beam 4 are connected by the wooden tenon connector 5. The wooden tenon connector 5 can simultaneously pass through and connect the two shrimp-whisker beams 6 and the large scissor beam 4 together, making the connection of the three more stable and firm. This connection method can avoid the problem of nails or pins coming loose, and at the same time can ensure that the shrimp-whisker beam 6 can stably and effectively support the large scissor beam 4 from both sides.

[0036] In the specific implementation process, the beam frame 2 has four side top surfaces, including two main side top surfaces 8 and two side side top surfaces 9 that are opposite to each other. The ridge purlin 1, together with the eaves boards 3 on the two main side top surfaces 8, presses the wooden rafters 7 on the corresponding side top surfaces onto the beam frame 2 through grooves. The side side top surfaces 9 are lower than the main side top surfaces 8 and are longitudinally connected to the lower part of the main side top surfaces 8. This type of roof structure is often used in public ancient buildings such as temples. The main side top surfaces 8 can be understood as the side top surfaces in the front and back directions, while the side side top surfaces 9 are the top surfaces on the left and right sides. The side side top surfaces 9 are connected and set below the left and right sides of the main side top surfaces 8. Such a roof structure can facilitate rainwater drainage and also has good structural aesthetics.

[0037] Preferably, the pressing groove is a square groove. The square groove structure can restrict the rotation of the wooden rafter 7, thus making it easier to press and fix.

[0038] It should be noted that some or all of the wooden components of the roof structure can be connected using mortise and tenon joints 5. For example, the four rafters 7 on the top sides are connected to the beam frame 2 using mortise and tenon joints 5, and the ridge purlin 1 is also fixed to the ridge purlin 1 using mortise and tenon joints 5. Figure 4 Only some wooden components are shown connected by dowels 5, but this is not a limitation. In actual implementation, it is preferred that most wooden components are connected by dowels 5.

[0039] Furthermore, since the main structure of the roof in this application embodiment is a restoration and pre-verification of the physical structure of the ancient building, the structures involved can all be used in the physical structure of the ancient building, such as the restoration of the ancient building, and are not limited to the ancient building model.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
