Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a method for removing wooden roof ridges. Background Technology

[0002] In some older residential areas, the buildings generally adopt pointed wooden ridge structures (also known as "wooden large ridge structures"). After decades of use, these buildings have entered a period of serious aging. The original wooden ridge structures have exposed many insurmountable defects in terms of safety, functionality and durability, which has become a key and difficult point in the current urban old residential area renovation and upgrading.

[0003] In the renovation of old residential areas, the demolition of wooden roof structures typically employs either mechanical force or manual demolition. Mechanical demolition often requires coordinating the relocation of residents and causes some damage to the original structure. Furthermore, it is limited by the difficulty of achieving a complete temporary relocation of all residents. Manual demolition involves workers separating and transporting wooden components such as rafters, tie rods, braces, and beams to the ground one by one. This method involves a large amount of work at height, is cumbersome, inefficient, time-consuming, and carries high safety risks, and can easily damage other parts of the building. Therefore, how to safely and efficiently complete the demolition of the original roof while minimizing disruption to residents' normal living conditions has become a critical issue that urgently needs to be addressed. Summary of the Invention

[0004] This invention provides a method for removing wooden roof ridges, which solves the problem of how to safely and efficiently remove the original roof while minimizing disruption to residents' normal living conditions.

[0005] This invention provides a method for removing a wooden roof ridge, comprising the following steps: The roof ridge to be demolished is divided into several construction sections according to the number of households, with each household being one construction section. Each construction section is divided into several construction units according to the ridge structure, and several construction units are demolished sequentially from the outside to the inside according to the ridge structure. The remaining construction units in the remaining construction sections were dismantled in sequence.

[0006] Beneficial effects: By adopting the method in this embodiment, the disruption to residents' lives is minimized, large-scale resident relocation is avoided, the impact of demolition work on residents' daily life and rest is reduced to the minimum, and the convenience of living is guaranteed. The construction section is divided into several construction units, which can achieve precise demolition, avoid key parts of the main building structure, and ensure that the original building structure, residents' interior decoration and furniture and appliances are not damaged. By demolishing one by one in an orderly manner, the risk of structural collapse caused by the overall operation is avoided, and the safety and controllability of demolition are improved.

[0007] In one alternative implementation, during the demolition of a construction unit, the rafters, sheaths, and purlins connecting the construction unit to be demolished to the adjacent construction unit need to be cut first.

[0008] Beneficial effects: By pre-cutting the connecting components, the stress transmission path is effectively blocked, avoiding accidental collapse caused by structural linkage during demolition. At the same time, the vibration impact on adjacent undemolished units is reduced, ensuring the connection stability between the construction area and the retained structure.

[0009] In one alternative implementation, during the dismantling of a construction unit, a lifting device is used to lift all the construction units to be dismantled.

[0010] Beneficial effects: By using lifting equipment to remove the completed construction units, the risks of manually disassembling components one by one at height were avoided, significantly reducing the probability of accidents such as workers falling or being struck by objects. At the same time, the lifting method improved construction efficiency and reduced the continuous disturbance to the surrounding environment caused by working at height. During the lifting process, the construction units maintained structural integrity, preventing components from scattering and posing a safety threat to the area below, thus ensuring the safety of personnel and property around the construction site.

[0011] In one alternative implementation, before using lifting equipment, lifting points need to be set in the construction unit to be demolished, and the sheathing boards at the lifting points need to be removed. The wire ropes are then fixed to the rafters of the construction unit to be demolished, and the entire construction unit is then lifted using lifting equipment.

[0012] Beneficial effects: By pre-setting lifting points and removing some of the sheathing panels, stable fixing points were provided for the wire rope. The lifting point structure was designed with circular through holes, effectively dispersing the local pressure on the wire rope and preventing the rafters from breaking due to stress concentration. The operation of tightening the wire rope with a chain hoist ensured the balance of the component before lifting, avoiding the lifting risks caused by component tilting. The entire lifting process was closely coordinated with the cutting procedure of the connecting components, achieving both safety and efficiency in the dismantling operation.

[0013] In one alternative implementation, before the demolition of the construction unit to be demolished, a safety net is placed at the bottom of the construction unit to be demolished, and the fixing points of the safety net are treated to prevent slippage and detachment.

[0014] Beneficial effects: The installation of the safety net effectively prevents accidental falling of wooden components during dismantling, thus protecting personnel and property below. Anti-slip and anti-detachment measures ensure the net remains stable during lifting, avoiding safety risks caused by slippage or detachment. Wrapping the construction unit with the net reduces the area where components may scatter, facilitating subsequent cleanup work.

[0015] In one alternative implementation, the dividing point between adjacent construction units is the intersection of the diagonal brace and the rafter.

[0016] Beneficial effects: The intersection of the diagonal brace and the rafter is used as the dividing point between adjacent units, a critical node for structural stress transformation. This division method ensures the structural independence of each construction unit while avoiding cutting the main load-bearing components, thus guaranteeing the stability of the original building structure during demolition. Furthermore, the connection between the diagonal brace and the rafter at the intersection is relatively weak, facilitating precise cutting and improving demolition efficiency.

[0017] In one alternative implementation, when setting several construction units for a construction section, it is also necessary to perform finite element analysis of the stress conditions.

[0018] Beneficial effects: A three-dimensional model of the roof ridge structure was established using finite element analysis software to simulate stress distribution and deformation under different construction unit division schemes. Based on the analysis results, the boundary positions of the construction units were optimized to ensure that each unit is subjected to reasonable stress during demolition and to avoid structural instability caused by local stress concentration. This analysis can also provide a theoretical basis for key procedures such as lifting point setting and lifting sequence, further improving construction safety and scientific rigor.

[0019] In one alternative implementation, after each construction section has been demolished, a tarpaulin needs to be erected at the site of the demolition.

[0020] Beneficial effects: Rainproof tarpaulins can prevent rainwater leakage during construction, avoiding damage to the original building structure, residents' interior decoration, furniture, and appliances.

[0021] In one alternative implementation, the steel roof structure is erected after each construction section has been demolished.

[0022] Beneficial effects: After each construction section is demolished, the construction of the steel structure roof is started immediately. The rapid construction of the steel structure roof not only restores the building's functionality in a timely manner and reduces the inconvenience caused to residents by the lack of a roof, but also improves the overall construction progress.

[0023] In one alternative implementation, residents within a construction section need to be relocated before each section is demolished, while residents in other construction sections will be relocated during the demolition process.

[0024] Beneficial effects: This approach ensures construction safety, minimizes the time and scope of disruption to residents' lives, and avoids the coordination difficulties and additional costs associated with large-scale relocation. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The following is combined Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a method for removing a wooden roof ridge is provided, comprising the following steps: The roof ridge to be demolished is divided into several construction sections based on the number of households, with each household serving as one construction section.

[0030] Each construction section is divided into several construction units according to the ridge structure, and several construction units are demolished sequentially from the outside to the inside according to the ridge structure. The remaining construction units in the remaining construction sections were dismantled in sequence.

[0031] Specifically, the roof ridge to be demolished is first divided into several construction sections based on the number of households. The number of construction sections can be determined according to the number of households, with each household constituting one construction section. When demolishing the roof ridge in any construction section, only the residents within that section need to vacate; residents in other construction sections do not need to vacate. The construction section to be demolished is then divided into several construction units based on the roof ridge structure, and during demolition, the construction units are demolished sequentially from the outside in. For example... Figure 1 and Figure 2 As shown, this construction section is divided into three construction units: a first construction unit 1, a second construction unit 2, and a third construction unit 3. The first and second construction units 1 and 2 are located on either side of the third construction unit 3. During demolition, the ridges of the first and second construction units 1 and 2 must be dismantled first, either sequentially in the order of the first construction unit 1 and the second construction unit 2, or in the order of dismantling the second construction unit 2 first and then the first construction unit 1. After the ridges of the first and second construction units 1 and 2 are dismantled, the ridge of the third construction unit 3 is then dismantled. Finally, the remaining construction sections are demolished sequentially in the same manner.

[0032] By adopting the method in this embodiment, the disruption to residents' lives is minimized, large-scale resident relocation is avoided, the impact of demolition work on residents' daily life and rest is reduced to the minimum, and the convenience of living is guaranteed. The construction section is divided into several construction units, which can achieve precise demolition, avoid key parts of the main building structure, and ensure that the original building structure, residents' interior decoration and furniture and appliances are not damaged. By demolishing one by one in an orderly manner, the risk of structural collapse caused by the overall operation is avoided, and the safety and controllability of demolition are improved.

[0033] Furthermore, during the demolition of a construction unit, it is necessary to first cut the rafters, roof boards, and purlins connecting the construction unit to be demolished to the adjacent construction unit.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, when dismantling the first construction unit 1, the rafters are first cut along the AA direction. Then, workers standing on the roof of the third construction unit 3 cut the rafters, sheathing, and purlins along the AB direction. When dismantling the second construction unit 2, the rafters are first cut along the CC direction. Then, workers standing on the roof of the third construction unit 3 cut the rafters, sheathing, and purlins along the CD direction. When dismantling the third construction unit 3, the rafters are cut along the EE direction.

[0035] By pre-cutting the connecting components, the stress transmission path is effectively blocked, preventing accidental collapses caused by structural linkages during demolition. This also reduces vibration impact on adjacent undemolished units, ensuring the stability of the connection between the construction area and the retained structure. The cutting operation employs a directional segmented cutting method, combined with a 45° oblique cutting angle design for the rafters. This ensures complete separation of components while avoiding damage to the main load-bearing structure due to excessive cutting.

[0036] Furthermore, during the dismantling of the construction units, lifting equipment is used to lift all the construction units to be dismantled.

[0037] Specifically, such as Figure 2 As shown, after the connecting components of the construction unit are removed, the entire construction unit to be demolished is lifted away using lifting equipment.

[0038] By using lifting equipment to remove the completed construction units, the risks of manually disassembling components one by one at height were avoided, significantly reducing the probability of accidents such as workers falling or being struck by objects. At the same time, the lifting method improved construction efficiency and reduced the continuous disturbance to the surrounding environment caused by working at height. During the lifting process, the construction units maintained structural integrity, preventing components from scattering and posing a safety threat to the area below, thus ensuring the safety of personnel and property around the construction site.

[0039] Furthermore, before using lifting equipment, it is necessary to set up lifting points in the construction unit to be demolished, remove the sheathing boards at the lifting points, fix the wire rope to the rafters of the construction unit to be demolished, and then use lifting equipment to lift the entire construction unit.

[0040] Specifically, before cutting the connecting components of the construction unit to be demolished, it is necessary to set up lifting points in the construction unit. Based on the construction requirements and stress analysis, the number of lifting points to be set up is determined. Then, the sheathing boards at the set lifting points are removed, so that the lifting point structure is a circular through hole. The steel wire rope passes through the through hole and is fixed to the rafters of the construction unit to be demolished. The steel wire rope is tightened with a chain hoist. The component is first lifted by hoisting equipment, and then the connecting components of the construction unit are cut. Finally, the construction unit to be demolished is lifted up by the hoisting equipment to complete the demolition of the construction unit.

[0041] By pre-setting lifting points and removing some of the sheathing panels, stable fixing points were provided for the wire rope. The lifting point structure was designed with circular through holes, effectively dispersing the local pressure on the wire rope and preventing the rafters from breaking due to stress concentration. The operation of tightening the wire rope with a chain hoist ensured the balance of the component before lifting, avoiding the lifting risks caused by component tilting. The entire lifting process was closely coordinated with the cutting procedure of the connecting components, achieving both safety and efficiency in the dismantling operation.

[0042] Furthermore, before dismantling the construction unit to be demolished, a safety net is placed at the bottom of the construction unit to be demolished, and the fixing points of the safety net are treated to prevent slippage and detachment.

[0043] Specifically, before the hoisting equipment lifts the construction unit to be demolished, a safety net is placed at the bottom of the construction unit to be demolished. The safety net covers the construction unit to be demolished, and the four corners of the safety net correspond to the four corners of the construction unit to be demolished. The four corners of the safety net are suspended from the hoisting equipment hooks by ropes passing through the sheathing board to ensure that the safety net can effectively catch the wooden components when they fall. During installation, the integrity of the safety net is checked, and the fixing points of the safety net are treated with anti-slip and anti-detachment measures.

[0044] The installation of the safety net effectively prevents accidental falling of wooden components during dismantling, thus protecting personnel and property below. Anti-slip and anti-detachment measures ensure the net remains stable during lifting, avoiding safety risks caused by slippage or detachment. Wrapping the construction unit with the net reduces the area where components may scatter, facilitating subsequent cleanup work.

[0045] Furthermore, the dividing point between adjacent construction units is the intersection of the diagonal brace and the rafter.

[0046] Specifically, such as Figure 2 As shown, when dividing the construction units, the intersection of the diagonal brace and the rafter is used as the dividing point between adjacent units. This location is a critical node for structural stress transformation. This division method ensures the structural independence of each construction unit while avoiding cutting the main load-bearing components, thus ensuring the stability of the original building structure during demolition. Simultaneously, the connection between the components at the intersection of the diagonal brace and the rafter is relatively weak, facilitating precise cutting operations and improving demolition efficiency.

[0047] Furthermore, when setting up several construction units for a construction section, it is also necessary to conduct finite element analysis of the stress conditions.

[0048] Specifically, the division of construction units requires not only consideration of the unit's structure but also the creation of a 3D model of the ridge structure using finite element analysis software to simulate stress distribution and deformation under different unit division schemes. Based on the analysis results, the boundary positions of the construction units are optimized to ensure reasonable stress distribution during dismantling and prevent structural instability caused by localized stress concentration. This analysis also provides a theoretical basis for key procedures such as hoisting point selection and lifting sequence, further enhancing construction safety and scientific rigor.

[0049] Furthermore, after each construction section is demolished, a rain shelter needs to be erected at the demolished site.

[0050] Specifically, after each construction section is completed, the construction workers must immediately erect a waterproof tarpaulin over the demolition area to prevent rainwater leakage during construction and avoid damage to the original building structure, residents' interior decoration, furniture and appliances.

[0051] Furthermore, once each construction section is demolished, the steel structure roof is constructed.

[0052] Specifically, the construction of the steel structure roof begins immediately after the demolition of each construction section is completed and the tarpaulin is erected. The rapid construction of the steel structure roof not only restores the building's functionality in a timely manner and reduces inconvenience to residents caused by the lack of a roof, but also improves the overall construction progress.

[0053] Furthermore, before each construction section is demolished, the residents within that section must be relocated, while the residents in the remaining construction sections will be relocated during the demolition process.

[0054] Specifically, for each construction section to be demolished, the relocation time must be communicated with the residents in that section in advance to ensure that the evacuation is completed before the demolition work begins. For construction sections that have not yet been demolished, residents can continue to live normally, and will only temporarily relocate according to the pre-arranged plan when their own construction section is about to be demolished. This phased relocation method not only ensures construction safety, but also minimizes the time and scope of disruption to residents' lives, while avoiding the coordination difficulties and additional costs caused by large-scale centralized relocation.

[0055] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
