Description

Technical Field

[0001] This invention relates to the field of construction technology for ancient and imitation ancient buildings, and in particular to a bracket set connector, a prefabricated bracket set, a wooden roof structure, and a construction method thereof. Background Technology

[0002] Traditional timber structures use natural wood as raw material and mortise and tenon joints to reduce cross-sectional dimensions as the main connection method. Over long-term use, timber structures are susceptible to damage from biological agents, the natural environment, and earthquakes. Traditional timber structures have at least the following drawbacks:

[0003] 1. The brackets and roof require a large number of loose wooden components to be assembled on site. The processing precision of the wooden components is high, the assembly is time-consuming and labor-intensive, and the construction efficiency is low.

[0004] 2. The connection nodes of the bracket sets dissipate energy through friction and compression between the wooden components. They are prone to damage under external loads, have low seismic performance, and poor structural durability.

[0005] 3. Mortise and tenon structures achieve connection through the interlocking of tenons and mortises. However, the weakening of the wooden component by the tenons and mortises will reduce the strength of the connection node. Once the contact surface shifts, the overall stability of the mortise and tenon structure will decrease.

[0006] 4. The wooden components of the mortise and tenon structure are interlocked. If a wooden component is damaged or rotten, it is difficult to disassemble and replace, which is not conducive to later maintenance.

[0007] 5. It is difficult to install concealed fire pipes and sprinkler systems inside wooden roof structures, resulting in low fire safety reliability. Summary of the Invention

[0008] To address the problems of low assembly efficiency, poor seismic performance, and difficulty in disassembling and replacing wooden components in existing wooden structures, the present invention aims to provide a bracket set connector, a prefabricated bracket set, a wooden roof structure, and a construction method thereof.

[0009] The technical solution adopted by this invention to solve its technical problem is: a bracket set connector, comprising: an energy-dissipating connector and a frame connector. The energy-dissipating connector includes two right-angle members, a long strip pad, two rubber layers, and a self-tapping screw. Each right-angle member has a bolt hole on one side and a connecting ear plate vertically fixed to its other side. The two right-angle members are arranged opposite each other and assembled into a frame with a hollow inner cavity. The long strip pad is disposed through the middle of the inner cavity of the frame. The two rubber layers are respectively attached to both sides of the long strip pad, so that the right-angle members, rubber layers, and long strip pad... The components are integrated and have through bolt holes. One end of the self-tapping screw passes through the right-angle member, rubber layer, and long strip pad to be detachably connected to the wooden column. The other end is detachably connected to the frame connector. Two connecting ear plates and the two ends of the long strip pad exposed outside the rubber layer are respectively provided with bolt holes, so that the wooden arches located around the energy-consuming connector can be bolted to the connecting ear plates and long strip pads of the energy-consuming connector. The two sides of the frame connector are bolted to the wooden arches and wooden brackets respectively, and its top side is bolted to the wooden structure roof. The wooden beams pass through the frame connector and are supported by the hopper.

[0010] The bracket set connector of the present invention includes an energy-dissipating connector and a frame connector. The energy-dissipating connector includes two right-angled members arranged opposite each other, two layers of rubber and a long strip pad disposed in the inner cavity of the two right-angled members, and two connecting ear plates respectively vertically connected to the side plates of the two right-angled members. A self-tapping screw vertically penetrates the right-angled members, the rubber layers and the long strip pad, and is detachably connected to the wooden column and the frame connector respectively. The connecting ear plates and the long strip pad of the energy-dissipating connector are respectively connected to the wooden bracket bolts located around the energy-dissipating connector. The two sides of the frame connector are respectively connected to the wooden bracket and the wooden bracket bolts, and its top is detachably connected to the wooden roof structure, thereby realizing the prefabricated assembly and construction of the bracket set and its connection with the wooden roof structure. Compared with the traditional mortise and tenon connection structure, the bracket set connector of the present invention and the... Bolted connections between wooden components enable prefabricated construction of the dougong (bracket set), facilitating quick and easy installation and disassembly. This avoids the tedious assembly of numerous components required in traditional dougong, improving installation efficiency. Rubber layers are integrated between right-angle components and long strip pads in the dougong connectors, enhancing the load-bearing capacity, overall seismic performance, and durability of the wooden dougong structure. After assembly, the bottom of the energy-dissipating connectors is concealed by the four lugs of the dougong bracket, while the sides are surrounded by the surrounding wooden dougong, preserving the aesthetic appearance of the ancient wooden building. Furthermore, since all connections between the dougong connectors and the wooden components are bolted, workers can quickly and easily remove and replace damaged or decayed components, reducing maintenance and repair difficulties.

[0011] Furthermore, the energy-consuming connector is a frame with a hollow inner cavity formed by splicing two right-angled components arranged opposite each other. A long strip pad is set in the middle of the inner cavity, and a rubber layer is set between the right-angled components and the long strip pad, and they are firmly bonded together by a high-temperature vulcanization process.

[0012] Furthermore, the wooden arches around the energy-consuming connector are provided with slots corresponding to the connecting ear plates and long strip pads. The connecting ear plates and long strip pads of the energy-consuming connector are respectively snapped together with the wooden arches and fastened with countersunk bolts.

[0013] Furthermore, the frame connector is a hollow rectangular frame made up of four side plates, and the hollow inner cavity of the frame connector matches the cross-sectional dimensions of the timber. Each of the four side plates of the frame connector is provided with bolt holes. The side plate located at the top is bolted to the steel structure roof truss support, the side plate located at the bottom is bolted to the energy-consuming connector, and the side plates located on both sides are bolted to the timber purlin and the timber arch respectively. The timber passes through the hollow inner cavity of the frame connector and is supported by the hopper below it.

[0014] The present invention also provides a prefabricated bracket set, which includes a bracket set connector and a bracket set wooden component consisting of at least a wooden ang, a wooden arch, a wooden beam, and a bracket set. The screw of the energy-consuming connector passes through the bracket set and is detachably connected to the top of the wooden column. The two connecting ear plates and the two ends of the long strip pad of the energy-consuming connector are respectively bolted to four wooden arch bolts set around it. The bottom side plate of the frame connector is bolted to the top of the energy-consuming connector. The top side plate of the frame connector is bolted to the steel structure roof truss support. The side plates on both sides of the frame connector are respectively bolted to the wooden ang and the wooden arch. The wooden beam passes through the hollow inner cavity of the frame connector and is supported by the scattered bracket at its bottom.

[0015] The prefabricated bracket set of this invention includes bracket set connectors and wooden bracket set components. The screws of the energy-dissipating connectors pass through the bracket set and are detachably connected to the top of the wooden column. The two connecting ear plates and the ends of the long strip pad of the energy-dissipating connectors are respectively connected to four wooden bracket set bolts arranged around them. A frame connector is bolted to the top of the energy-dissipating connector. The top of the frame connector is bolted to the steel roof truss support. Both sides of the frame connector are bolted to the wooden brackets and wooden beams respectively. The wooden beams pass through the inner cavity of the frame connector and are supported by the bracket set. Compared to traditional mortise and tenon joint wooden bracket sets, the bracket set connectors are assembled from steel components and bolted to each wooden bracket set component, achieving prefabricated construction of the bracket set. Installation and disassembly are convenient and quick, avoiding the large size of traditional bracket sets. The tedious assembly of components improves the installation efficiency of the bracket set; the dual shock absorption effect of energy-dissipating connectors and frame connectors effectively enhances the overall seismic performance of the prefabricated bracket set, improves its load-bearing capacity, and makes it more durable; after the bracket set is assembled, the bottom of the energy-dissipating connector is covered by the four ears of the bracket set and is not exposed, and its sides are hidden between the wooden components, so as not to affect the appearance of the ancient wooden building; moreover, the bracket set connectors and the wooden components of the bracket set are all detachable, so if a wooden component is damaged, the construction workers can quickly remove and replace it, reducing the difficulty of maintenance and repair of the bracket set. Therefore, this prefabricated bracket set has the advantages of easy installation, easy disassembly and maintenance, and strong seismic performance.

[0016] This invention also provides a wooden roof structure, comprising: prefabricated brackets, steel roof truss supports, and a wooden roof structure. The steel roof truss supports include a ridge, support legs, and roof fixing components. A pair of support legs are connected to each end of the ridge. Each support leg has bolt holes along its length corresponding to the positions of the wooden purlins of the wooden roof structure, allowing the wooden purlins of the wooden roof structure to be bolted to the support legs. Each support leg has a bolt hole at its bottom corresponding to the position of the top side plate of the frame connector, allowing the support leg to be bolted to the frame connector of the brackets. The roof fixing components have an L-shaped cross-section and are the same length as the ridge. Two roof fixing components are inverted and symmetrically arranged on both sides of the ridge. One side of the roof fixing component is connected to the ridge, and the other side is connected to the support leg, allowing the roof fixing component, the ridge, and the support legs to form a through cavity as a reserved passage for fire-fighting pipes. Bolt holes are provided on both sides of the roof fixing component, and the ends of the wooden rafters of the wooden roof structure are bolted to the roof fixing component.

[0017] The wooden roof structure of this invention includes, from bottom to top, a prefabricated bracket set detachably connected to the top of wooden columns, a steel roof truss support, and a wooden roof structure. The steel roof truss support includes a ridge, with support legs connected to both ends of the ridge. The wooden purlins of the wooden roof structure are bolted to the top of the support legs, and the bottom of the support legs are bolted to the frame connectors of the prefabricated bracket set. Roof fixing components are inverted and symmetrically arranged on both sides of the ridge, allowing the roof fixing components, the ridge, and the support legs to form a through cavity as a reserved channel for fire-fighting pipes. The ends of the wooden rafters of the wooden roof structure are bolted to the roof fixing components. The steel roof truss support is detachably connected to the prefabricated bracket set at its bottom and bolted to the wooden roof structure at its top. The wooden roof structure of this invention utilizes energy... The energy-dissipating connectors and frame connectors serve as prefabricated steel structure connectors, enabling rapid on-site assembly through bolted connections between the steel structure connectors and the dougong (bracket set) wooden components. Installation and disassembly are convenient and quick, avoiding the tedious assembly of numerous dougong wooden components in traditional wooden structures, thus improving installation efficiency and facilitating later maintenance and replacement. The dual shock-absorbing effect of the energy-dissipating connectors and frame connectors effectively improves the seismic performance and load-bearing capacity of the wooden roof. Pre-reserved channels for fire-fighting pipes are provided within the roof fixing components, facilitating the installation of concealed fire-fighting pipes and sprinkler systems, enhancing the fire resistance of the wooden roof. Furthermore, after the wooden roof is assembled, all steel components of the dougong connectors are hidden within the dougong wooden components, without affecting the appearance of the wooden building. Therefore, the wooden roof of this invention can improve the overall seismic performance, joint load-bearing capacity, and fire resistance of the wooden building while maintaining its appearance, resulting in higher structural reliability. This invention is particularly suitable for the construction of ancient or imitation ancient buildings.

[0018] Furthermore, the wooden roof structure is composed of wooden purlins, wooden rafters, roof panels, waterproof membrane 74, and shingle joists connected from bottom to top. The horizontally spaced wooden purlins are bolted to the support legs on both sides of the steel roof truss support. The longitudinally spaced wooden rafters rest on the top of the wooden purlins, and the ends of the wooden rafters are bolted to the roof fixing parts of the steel roof truss support. The roof panels and waterproof membrane are laid on the top of the wooden rafters.

[0019] In addition, the present invention also provides a construction method for a wooden roof, the steps of which are as follows:

[0020] S1: Prefabricated bracket set connectors and steel roof truss supports are transported to the construction site for assembly. Self-tapping screws are drilled into the center point of the top section of the wooden column. After the construction of the platform base of the wooden structure is completed, the wooden column is erected on the column base and temporarily fixed. The bracket set and energy-consuming connector are placed in sequence along the self-tapping screws inserted into the top of the wooden column. The two connecting ear plates and the two ends of the long strip pad of the energy-consuming connector are inserted into the wooden bracket set and bolted together.

[0021] S2: Insert the frame connector into the top of the energy-consuming connector along the self-tapping screw and tighten it. The side plates on both sides of the frame connector are bolted to the wooden brackets and wooden arches respectively. The wooden beams pass through the hollow inner cavity of the frame connector and are supported on the brackets. Align the four support legs of the structural roof truss with the top of the four prefabricated brackets respectively. The bolts pass through the support legs and are inserted into the top side plate of the frame connector to lock and fix them, so that the four support legs are bolted to the four prefabricated brackets respectively.

[0022] S3: Assemble the wooden roof structure. The wooden purlins of the wooden roof structure are bolted to the support legs on both sides of the steel roof truss support. The top of the wooden rafters of the wooden roof structure is bolted to the roof fasteners. After the wooden roof structure and the steel roof truss support are assembled, fire-fighting pipes are laid in the reserved channel for fire-fighting pipes in the steel roof truss support.

[0023] The construction method of the wooden roof structure of this invention involves first prefabricating the bracket set connectors, steel roof truss supports, and wooden roof structure. Wooden columns are erected on column bases, and self-tapping screws are drilled into the center of their tops. The bracket sets and energy-dissipating connectors are then placed sequentially along the self-tapping screws. The two connecting lugs and the long strip pads of the energy-dissipating connectors are bolted to the wooden brackets at both ends. A frame connector is inserted and tightened at the top of the energy-dissipating connector along the self-tapping screws. The two sides of the frame connector are bolted to the wooden brackets and wooden trusses, respectively. Wooden beams pass through the hollow inner cavity of the frame connector and are supported by the brackets below. The four support legs of the steel roof truss support are bolted to the frame connectors of the four prefabricated bracket sets. The wooden purlins of the wooden roof structure are bolted to the support legs on both sides of the steel roof truss support. The top of the wooden rafters of the wooden roof structure are bolted to the roof fixing components. After the wooden roof structure and steel roof truss support are assembled, fire-fighting pipes are laid in the reserved channel for fire-fighting pipes within the steel roof truss support. Compared to the mortise and tenon joints of traditional wooden structures, the dougong (bracket set) connectors are bolted to the horizontal wooden brackets and other wooden components. These connectors are also detachably connected to the vertical wooden columns and steel roof trusses. The prefabricated, modular steel components reduce the number of connecting parts in the wooden structure, making installation and disassembly quick and easy. This avoids the tedious assembly of numerous components found in traditional dougong systems, improving installation efficiency. Furthermore, the bolted connections between the dougong connectors and the wooden components and steel roof trusses enable on-site assembly of the wooden roof, simplifying operation, increasing construction efficiency, and reducing construction costs. Furthermore, damaged or broken wooden components can be quickly replaced, facilitating later disassembly and maintenance. The use of energy-dissipating connectors and frame connectors as steel structure connectors enables the prefabricated assembly of various wooden components in the bracket set, enhancing the structural strength of each connection node in the wooden roof and resulting in superior overall seismic resistance and durability. Reserved channels for fire sprinkler pipes are provided within the roof fasteners, improving the fire resistance of the wooden structure and solving the problem of installing concealed fire extinguishing devices in traditional wooden structures. All bracket set connectors and fastening bolts are hidden inside the wooden components, ensuring no impact on the building's appearance.

[0024] Furthermore, in step S1, the four wooden arches on the upper layer of the bracket set are provided with slots at the connection points corresponding to the energy-consuming connectors. The slots of the four wooden arches are respectively inserted into the two ends of the connecting ear plates and the long strip pad, and countersunk bolts are inserted to tighten them.

[0025] Furthermore, the assembly steps of the wooden roof structure in step S3 are as follows: The wooden roof structure is assembled from bottom to top by wooden purlins, wooden rafters, roof panels, waterproof membrane, and shingle joists. First, the horizontally spaced wooden purlins are bolted to the support legs on both sides of the steel roof truss support. The longitudinally spaced wooden rafters are placed on top of the wooden purlins, and the ends of the wooden rafters are bolted to the roof fixing components of the steel roof truss support. Next, the roof panels and waterproof membrane are laid on top of the wooden rafters. Finally, the shingle joists are fixed to the waterproof membrane with self-tapping screws. After the steel roof truss support and the wooden roof structure are assembled, fire pipes are laid in the fire pipe reserved channel of the roof fixing components. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" used below are consistent with the upper and lower directions in the drawings, but this should not be construed as a limitation of the technical solution of the present invention.

[0037] Example 1

[0038] Combination Figures 2 to 4 The present invention describes a bracket set connector comprising: an energy-dissipating connector 10 and a frame connector 20. The energy-dissipating connector 10 includes two right-angle members 11, a long strip pad 14, two rubber layers 15, and a self-tapping screw 16. Each right-angle member 11 has a bolt hole on one side and a connecting ear plate 12 vertically fixed to its other side. The two right-angle members 11 are arranged opposite each other and assembled into a frame with a hollow inner cavity. The long strip pad 14 is disposed through the center of the inner cavity of the frame. The two rubber layers 15 are respectively attached to both sides of the long strip pad 14, that is, the two rubber layers 15 are respectively tightly disposed in the gap between the long strip pad 14 and the right-angle members 11, so that the right-angle members 11, the rubber layers 15, and the long strip pad 14 are connected as a whole and have a through bolt hole. One end of the rod 16 passes through the right-angle member 11, the rubber layer 15, and the long strip pad 14 and is detachably connected to the wooden column 2. The other end is detachably connected to the frame connector 20. The two connecting ear plates 12 and the two ends of the long strip pad 14 exposed outside the rubber layer 15 are respectively provided with bolt holes, so that the wooden arches 42 located around the energy-consuming connector 10 can be bolted to the connecting ear plates 12 and the long strip pad 14 of the energy-consuming connector 10. The two sides of the frame connector 20 are bolted to the wooden arches 42 and the wooden awns 44 respectively, and its top side is bolted to the wooden structure roof 70. The wooden beam 45 passes through the frame connector 20 and is supported by the dougong 43. Among them, the wooden arches 42 are upward-curved arch-shaped wooden members placed inside the dougong opening or parallel to the front of the building, and the wooden awns 44 are long members that are obliquely exposed in the dougong structure.

[0039] The bracket set connector of the present invention includes an energy-dissipating connector 10 and a frame connector 20. The energy-dissipating connector 10 includes two right-angled members 11 arranged opposite each other, two layers of rubber 15 and a long strip pad disposed in the inner cavity of the two right-angled members 11, and two connecting ear plates 12 respectively vertically connected to the side plates of the two right-angled members 11. A self-tapping screw 16 vertically penetrates the right-angled members 11, the rubber layers 15 and the long strip pad 14 and is detachably connected to the wooden column 2 and the frame connector 20 respectively. The connecting ear plates 12 and the long strip pad 14 of the energy-dissipating connector 10 are bolted to the wooden brackets 42 located around the energy-dissipating connector 10. The two sides of the frame connector 20 are bolted to the wooden brackets 44 and the wooden brackets 42 respectively, and its top is detachably connected to the wooden roof structure 70, thereby realizing the prefabricated assembly construction of the bracket set and its connection with the wooden roof structure 70; compared with the traditional mortise and tenon joint. The connection structure utilizes bolted connections between the bracket set connectors and wooden components to achieve prefabricated construction of the bracket set. Installation and disassembly are convenient and quick, avoiding the tedious assembly work of traditional bracket sets with numerous components, thus improving installation efficiency. Rubber layers 15 are integrated between the right-angle component 11 and the long strip pad 14 in the bracket set connectors, enhancing the load-bearing capacity, overall seismic performance, and durability of the wooden bracket set. After assembly, the bottom of the energy-dissipating connector 10 is concealed by the four ears of the bracket 41, and its sides are surrounded by the surrounding wooden brackets 42, ensuring no impact on the appearance of the ancient wooden building. Furthermore, since both the bracket set connectors and the wooden components are bolted, if a wooden component is damaged or decayed, construction workers can quickly and promptly remove and replace it, reducing the difficulty of maintenance and repair.

[0040] like Figure 2 As shown, the energy-dissipating connector 10 in this embodiment is a frame with a hollow inner cavity, formed by assembling two right-angled members 11 arranged opposite each other. A long strip pad 14 is disposed in the middle of the inner cavity. A rubber layer 15 is disposed between the right-angled members 11 and the long strip pad 14, and they are firmly bonded together by a high-temperature vulcanization process. The placement of the rubber layer 15 between two adjacent steel members and their firm connection through a high-temperature vulcanization process improves the structural strength and stability of the energy-dissipating connector 10, and also enhances its seismic performance. In this embodiment, the rubber layer 15 is preferably made of high-damping styrene-butadiene rubber.

[0041] like Figure 3 As shown, the wooden arches 42 located around the energy-consuming connector 10 are provided with slots at positions corresponding to the connecting ear plates 12 and the long strip pads 14. The connecting ear plates 12 and the long strip pads of the energy-consuming connector 10 are respectively snapped together with the wooden arches 42 and fastened with countersunk bolts. Slots are opened at the corresponding installation positions of the wooden arches 42 to facilitate the accurate positioning and installation of the wooden arches 42.

[0042] like Figure 4 As shown, the frame connector 20 is a hollow rectangular frame composed of four side plates connected together. The hollow inner cavity of the frame connector 20 matches the cross-sectional dimensions of the timber beam 45. Each of the four side plates of the frame connector 20 has bolt holes. The top side plate is bolted to the steel roof truss support 60, the bottom side plate is bolted to the energy-dissipating connector 10, and the side plates on both sides are bolted to the timber bracket 44 and the timber arch 42, respectively. The timber beam 45 passes through the hollow inner cavity of the frame connector 20 and is supported by the bracket set 43 below it. The assembled timber arch is detachably connected to the timber roof 70 via the frame connector 20. Furthermore, the frame connector 20 itself also has energy-dissipating and vibration-damping functions, thereby improving the seismic performance of the connection node between the timber roof 70 and the timber arch. In this embodiment, the frame connector 20 is made of a 25mm thick steel plate.

The two sides of the frame connector 20 are respectively bolted to the wooden brackets 44 and the wooden brackets 42. The wooden beam 45 passes through the inner cavity of the frame connector 20 and is supported by the bracket set 43. Compared with the traditional wooden bracket set with mortise and tenon structure connection, the bracket set connector is assembled from steel components and bolted to each wooden component of the bracket set to realize the prefabricated construction of the bracket set, which is convenient for installation and disassembly. The prefabricated bracket set 50 is quick to install, avoiding the tedious assembly of numerous components required in traditional bracket sets, thus improving installation efficiency. Through the dual shock absorption of the energy-dissipating connector 10 and the frame connector 20, the overall seismic performance of the prefabricated bracket set 50 is effectively improved, enhancing its load-bearing capacity and durability. After assembly, the bottom of the energy-dissipating connector 10 is concealed by the four ears of the bracket set 41, and its sides are hidden among the wooden components, without affecting the appearance of the ancient wooden building. Furthermore, the connections between the bracket set connectors and the wooden components are detachable, allowing for quick removal and replacement of damaged components, reducing maintenance and repair difficulties. Therefore, this prefabricated bracket set 50 offers advantages such as easy installation, easy disassembly and maintenance, and strong seismic resistance.

[0052] S1: Prefabricate the bracket set connectors and steel roof truss supports 60 and transport them to the construction site for assembly. Use an electric drilling machine to drill self-tapping screws 16 at the center point of the top section of the wooden column 2. Before drilling, pre-drill a hole to a depth of 600mm. The total length of the self-tapping screw 16 is 1300mm, the external thread diameter is 25mm, the actual drilling depth of the self-tapping screw 16 is 500mm, and the exposed length is 800mm; Construction of the platform base of the wooden structure building. After completion, the wooden column 2 is erected on the column base 1 and temporarily fixed. The temporary fixing method is determined according to the site conditions. Generally, wooden supports are used to tie the wooden column 2 diagonally. The center of the bracket 41 and the energy-consuming connector 10 are provided with vertical through holes with a diameter of 25mm. The bracket 41 and the energy-consuming connector 10 are inserted in sequence along the self-tapping screw 16 inserted at the top of the wooden column 2. The two connecting ear plates 12 and the long strip pad 14 of the energy-consuming connector 10 are inserted into the wooden bracket 42 and bolted together.

[0053] S2: Insert the frame connector 20 into the top of the energy-consuming connector 10 along the self-tapping screw 16 and tighten it. Embed bolt sleeves in the middle of the cross-section of the wooden antelope 44 and the wooden arch 42. A hexagonal head bolt passes through the middle of the outer side plate of the frame connector 20 and is screwed into the bolt sleeve of the wooden antelope 44 and tightened. Another hexagonal head bolt passes through the middle of the inner side plate of the frame connector 20 and is screwed into the bolt sleeve of the wooden arch 42 and tightened. The wooden beam 45 passes through the hollow inner cavity of the frame connector 20 and is supported on the hopper 43. The truck crane lifts the steel structure roof truss support 60 so that the four support legs 62 are respectively aligned and placed on the top of the four prefabricated brackets 50. The support legs 62 and the top side plate of the frame connector 20 are both reserved with threaded holes with a depth of 50mm. The bolts pass through the support legs 62 and are inserted into the top side plate of the frame connector 20 to lock and fix them so that the four support legs 62 are respectively bolted to the four prefabricated brackets 50.

[0054] S3: Assemble the wooden roof structure 70. The wooden purlins 71 of the wooden roof structure 70 are bolted to the support legs 62 on both sides of the steel roof structure truss support 60. The top of the wooden rafters 72 of the wooden roof structure 70 is bolted to the roof fixing parts 64. After the wooden roof structure 70 and the steel roof structure truss support 60 are assembled, the fire pipe 90 is laid in the fire pipe reserved channel of the steel roof structure truss support 60.

[0055] The construction method of the wooden roof structure of the present invention involves first prefabricating the bracket set connectors, steel roof truss supports 60, and wooden roof structure 70. Wooden columns 2 are erected on column bases 1, and self-tapping screws 16 are drilled into the center of their tops. Bracket sets 41 and energy-dissipating connectors 10 are then placed sequentially along the self-tapping screws 16. The two connecting lugs 12 and the long strip pads 14 of the energy-dissipating connectors 10 are bolted to the wooden brackets 42 at both ends. A frame connector 20 is inserted into the top of the energy-dissipating connector 10 along the self-tapping screws 16 and tightened. The two sides of the frame connector 20 are bolted to the wooden brackets 44 and 42, respectively. The timber beam 45 passes through the hollow inner cavity of the frame connector 20 and is supported by the hopper 43 below it. The four support legs 62 of the steel structure roof truss support 60 are bolted to the frame connectors 20 of the four prefabricated brackets 50 respectively. The timber purlins 71 of the timber roof 70 are bolted to the support legs 62 on both sides of the steel structure roof truss support 60. The top of the timber rafters 72 of the timber roof 70 is bolted to the roof fixing piece 64. After the timber roof 70 and the steel structure roof truss support 60 are assembled, the fire pipe 90 is laid in the fire pipe reserved channel of the steel structure roof truss support 60. Compared to the mortise and tenon joints of traditional wooden structures, this method utilizes bracket set connectors to bolt to wooden components such as the wooden brackets 42 and angs 44 located on its horizontal sides. The bracket set connectors are also detachably connected to the vertical wooden columns 2 and the steel roof truss supports 60. These prefabricated, modular steel components reduce the number of connecting components in the wooden structure, making installation and disassembly convenient and quick. This avoids the tedious assembly work of traditional bracket sets, improving installation efficiency. The bolted connections between the bracket set connectors and the wooden components and steel roof truss supports 60 enable on-site assembly of the wooden roof structure, simplifying operation, increasing construction efficiency, and reducing construction costs. The construction reduces labor costs and allows for quick replacement of damaged wooden components, facilitating later disassembly and maintenance. The use of energy-dissipating connectors 10 and frame connectors 20 as steel structure connectors enables the prefabricated assembly of various wooden components in the bracket set, enhancing the structural strength of each connection node in the wooden roof and resulting in superior overall seismic resistance and durability. A reserved channel for fire sprinkler pipes is provided within the roof fixing component 64, improving the fire resistance of the wooden structure and solving the problem of installing concealed fire extinguishing devices in traditional wooden structures. The bracket set connectors and fastening bolts are all hidden inside the wooden components, without affecting the architectural style of the wooden structure.

[0056] In step S1, the four wooden arches 42 on the upper layer of the bracket set 41 are provided with slots in the middle of the connection parts corresponding to the energy-consuming connector 10. The depth of the slots is 1 / 3 of the width of the wooden arches 42. The slots of the four wooden arches 42 are respectively inserted into the two ends of the connecting ear plates 12 and the long strip pads 14, and countersunk bolts are inserted to tighten them. Since the energy-consuming connector 10 is covered by the four ear plates of the bracket set 41 below it, the steel components of the energy-consuming connector 10 will not be exposed, and will not affect the overall appearance of the wooden structure building.

[0057] In step S3, the assembly steps of the wooden roof structure 70 are as follows: The wooden roof structure 70 is assembled from bottom to top by wooden purlins 71, wooden rafters 72, roof panels 73, waterproof membrane 74, and shingle joists 75. First, the horizontally spaced wooden purlins 71 are bolted to the support legs 62 on both sides of the steel roof truss support 60. Then, the longitudinally spaced wooden rafters 72 are placed on top of the wooden purlins 71, and the ends of the wooden rafters 72 are connected to the roof fixing parts 64 of the steel roof truss support 60. After bolting, roof panels 73 and waterproof membrane 74 are laid sequentially on top of the wooden rafters 72. Finally, the shingle joists 75 are fixed to the waterproof membrane 74 with self-tapping screws. After the steel roof truss support 60 and the wooden roof 70 are assembled, the truck crane is removed. Fire pipes 90 are laid in the fire pipe reserved channel of the roof fixing component 64. Roof tiles are laid on top of the shingle joists 75 to form a tile layer 80. The temporary support of the wooden column 2 is removed. The tightness of all bolts is checked to ensure that they are tightened in place.
