Description

Technical Field

[0001] This utility model relates to an eaves rafter assembly structure, specifically an eaves rafter assembly structure for ancient wooden buildings, belonging to the field of ancient building construction technology. Background Technology

[0002] Currently, in the field of ancient architecture, the wooden substructure of the roof is a crucial structural component. Specifically, it refers to the structural layer formed between the wooden rafters and the wooden sheathings they support. While seemingly ordinary, this layer plays a vital role in the overall health of the ancient building's roof. It not only ensures the roof's waterproofing and drainage functions but also affects the building's structural stability and durability. Problems with the wooden substructure, such as rotten rafters or warped sheathings, can lead to serious consequences like roof leaks and structural loosening, ultimately threatening the safety of the entire ancient building.

[0003] Existing roof rafter structures typically consist of two parallel main columns and two parallel eaves columns as the basic framework. Support purlins are securely fixed to the tops of the two main columns, while eaves purlins are installed on the tops of the two eaves columns. Multiple eaves rafters are evenly distributed and fixed between the support purlins and eaves purlins, collectively forming the main body of the rafter structure. However, assembling the eaves rafters is cumbersome and complex, as multiple rafters must be individually fixed between the support purlins and eaves purlins. This process not only consumes a significant amount of manpower and time but also demands high technical skills from construction workers, resulting in low overall construction efficiency and failing to meet the demands of modern construction projects for time and cost control. Therefore, this paper proposes a new prefabricated rafter assembly structure for traditional wooden buildings. Utility Model Content

[0004] In view of this, the present invention provides an assembly structure for the eaves rafters of a wooden ancient building to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a wooden ancient building eaves rafter assembly structure, including a main column, a supporting purlin and an eaves rafter, wherein the supporting purlin is fixedly connected to the top of the main column, and a connecting component is provided inside the supporting purlin, and the eaves rafter is installed above the supporting purlin through the connecting component;

[0006] The connecting assembly includes an assembly base, two limiting slides, a push plate, a threaded rod, a sleeve, a connecting nut, a limiting groove, and a sliding groove;

[0007] Both the slide groove and the limiting groove are formed inside the assembly base. The two limiting slides are symmetrically slidably connected to the inner sidewall of the limiting groove. The push plate is slidably connected to the inside of the slide groove. The top of the outer sidewall of the push plate is attached to the opposite surface of the two limiting slides. The connecting nut is embedded in the upper surface of the assembly base. The sleeve is fixedly connected to the outer sidewall of the threaded rod. The top of the sleeve abuts against the lower surface of the push plate.

[0008] More preferably, the top end of the threaded rod is threaded to the inner wall of the connecting nut, the threaded rod is rotatably and slidably connected to the inside of the push plate, and the sleeve is rotatably and slidably connected to the inside of the support purlin.

[0009] More preferably, the upper surface of the support purlin is provided with a lower mounting groove, and the outer side wall of the support purlin is provided with a groove.

[0010] More preferably, the lower part of the outer side wall of the mounting base is attached to the inner side wall of the lower mounting groove, and a stop block is bonded to the inside of the lower mounting groove.

[0011] More preferably, the outer side wall of the stop block is symmetrically fixedly connected with a stop plate, and the stop plate is bonded to the inner side wall of the groove.

[0012] More preferably, the lower surface of the eaves rafter is provided with an upper mounting groove, and the inner sidewall of the upper mounting groove is symmetrically provided with two slots.

[0013] More preferably, the top of the outer side wall of the mounting base is slidably connected to the inner side wall of the upper mounting groove, and the limiting slide is inserted into the inner side wall of the slot.

[0014] More preferably, the outer wall of the eaves rafter is attached to the outer wall of the stopper plate.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] This invention connects the eaves rafter to the mounting base, inserts the mounting base into the upper mounting groove, and then inserts a threaded rod from the bottom of the mounting base. Rotating the threaded rod engages with the connecting nut, causing the threaded rod to move the sleeve upwards. The sleeve pushes the push plate upwards, which in turn pushes two limiting slides into the slots, thus fixing the mounting base and the eaves rafter together. Since the bottom of the mounting base is fixedly connected to the supporting purlin, the assembly of the eaves rafter and the supporting purlin can be achieved. Compared to existing technologies, this invention, by setting up connecting components, enables rapid assembly of the eaves rafter, simplifies the operation steps, and improves the construction efficiency of antique-style buildings.

Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-7 As shown, this utility model embodiment provides a wooden ancient building eaves rafter assembly structure, including a main column 33, a supporting purlin 32 and an eaves rafter 31. The supporting purlin 32 is fixedly connected to the top of the main column 33. A connecting component 101 is provided inside the supporting purlin 32. The eaves rafter 31 is installed above the supporting purlin 32 through the connecting component 101.

[0030] The connecting assembly 101 includes an assembly base 11, two limiting slides 12, a push plate 13, a threaded rod 14, a sleeve 15, a connecting nut 16, a limiting groove 18, and a slide groove 19;

[0031] Both the slide groove 19 and the limiting groove 18 are opened inside the assembly base 11. Two limiting slides 12 are symmetrically slidably connected to the inner side wall of the limiting groove 18. The opposite surfaces of the two limiting slides 12 are both inclined surfaces.

[0032] The push plate 13 is slidably connected to the inside of the slide groove 19. The top of the outer wall of the push plate 13 is in contact with the opposite surfaces of the two limiting slides 12. Both sides of the top of the push plate 13 are provided with inclined surfaces. When the push plate 13 moves upward, the push plate 13 contacts the limiting slides 12 through the corresponding inclined surfaces. After the limiting slides 12 are pushed, they slide in the limiting groove 18. The two limiting slides 12 move away from each other.

[0033] The connecting nut 16 is fitted into the upper surface of the mounting base 11, the sleeve 15 is fixedly connected to the outer wall of the threaded rod 14, the top end of the sleeve 15 abuts against the lower surface of the push plate 13, the top end of the threaded rod 14 is threaded to the inner wall of the connecting nut 16, the threaded rod 14 is rotatably and slidably connected to the inside of the push plate 13, and the sleeve 15 is rotatably and slidably connected to the inside of the support purlin 32. The position of the threaded rod 14 can be limited by the sleeve 15.

[0034] When the threaded rod 14 is rotated, it engages with the connecting nut 16. Since the position of the connecting nut 16 is fixed, the threaded rod 14 moves upward. The threaded rod 14 drives the sleeve 15 to move upward, and the sleeve 15 pushes the push plate 13 upward. The push plate 13 moves upward along the slide groove 19. At the same time, the push plate 13 pushes the two limit slides 12, thereby driving the limit slides 12.

[0035] In one embodiment, the upper surface of the support purlin 32 is provided with a lower mounting groove 24, the outer side wall of the support purlin 32 is provided with a groove 23, the lower part of the outer side wall of the mounting base 11 is attached to the inner side wall of the lower mounting groove 24, and the bottom of the mounting base 11 is in the shape of a dovetail.

[0036] A stop block 21 is bonded to the inside of the lower assembly groove 24. A stop plate 22 is symmetrically fixed to the outer side wall of the stop block 21. The stop plate 22 is bonded to the inner side wall of the groove 23. When the position of the stop block 21 is fixed, the position of the assembly seat 11 can be limited, thereby fixing the assembly seat 11 to the support purlin 32.

[0037] The stopper plate 22 can enhance the stability of the stopper 21 and prevent the stopper 21 from falling out of the lower mounting groove 24. The outer wall of the eaves rafter 31 is attached to the outer wall of the stopper plate 22, and the stopper plate 22 can support the eaves rafter 31.

[0038] In one embodiment, an upper mounting groove 26 is provided on the lower surface of the eaves rafter 31. Two slots 27 are symmetrically provided on the inner sidewall of the upper mounting groove 26. The top of the outer sidewall of the mounting base 11 is slidably connected to the inner sidewall of the upper mounting groove 26. The limiting slide 12 is inserted into the inner sidewall of the slot 27. When the push plate 13 pushes the two limiting slides 12 upward, the two limiting slides 12 are inserted into the inside of the slot 27, thereby fixing the mounting base 11 to the eaves rafter 31. Since the bottom of the mounting base 11 is fixedly connected to the supporting purlin 32, the assembly of the eaves rafter 31 and the supporting purlin 32 can be realized.

[0039] In operation, the following steps are performed: The bottom of the mounting base 11 is inserted into the lower mounting groove 24. Adhesive is applied to the surfaces of the stop block 21 and the plug plate 22. The stop block 21 is then bonded to the lower mounting groove 24, and the plug plate 22 is bonded to the groove 23. This defines the position of the mounting base 11. Then, the eaves rafter 31 is lifted and aligned with the mounting base 11. The mounting base 11 is then inserted into the upper mounting groove 26. Next, the threaded rod 14 is inserted from the bottom of the mounting base 11. The threaded rod 14 passes through the push plate 13 and aligns with the connecting nut 16. The threaded rod is then rotated... The rod 14 is screwed into the connecting nut 16. Since the position of the connecting nut 16 is fixed, the threaded rod 14 moves upward. The threaded rod 14 drives the sleeve 15 to move upward. The sleeve 15 pushes the push plate 13 upward. The push plate 13 moves upward along the slide groove 19. At the same time, the push plate 13 pushes the two limiting slides 12. The two limiting slides 12 are inserted into the inside of the slot 27, so that the mounting base 11 and the eaves rafter 31 can be fixedly connected. Since the bottom of the mounting base 11 is fixedly connected to the support purlin 32, the assembly of the eaves rafter 31 and the support purlin 32 can be realized.

[0040] Compared with the existing technology, this utility model can realize the rapid assembly of the eaves rafters 31 by setting the connecting component 101, which simplifies the operation steps and improves the construction efficiency of the antique building.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
