Description

Technical Field

[0001] This invention relates to the field of ancient building protection technology, specifically to a permanent-temporary combined system for dismantling and supporting immovable cultural relic structures and its construction method. Background Technology

[0002] In the protection and renovation of immovable cultural relics, there is often a construction requirement to "preserve the exterior walls while completely demolishing and rebuilding the internal structure." Such projects require the complete removal of the internal frame columns, frame beams, and load-bearing interior walls, while preserving the existing load-bearing exterior walls and historical features, and the construction of a new internal structural system to achieve functional upgrades. However, ensuring the stability of the exterior walls is a key challenge during the demolition of the internal structure.

[0003] Currently, for the preservation of the exterior walls and the demolition of the interior of immovable cultural relics, existing technologies mainly employ temporary support systems to reinforce and protect the exterior walls. For example, a space frame structure or truss support system composed of steel sections and pipes is used to temporarily reinforce the exterior walls of historical buildings. However, existing temporary support systems often require numerous holes to be drilled into the exterior walls during construction to install connecting components, or irreversible connection methods such as welding, causing varying degrees of damage to the cultural relic itself. As immovable cultural relics are non-renewable historical and cultural resources, any additional damage contradicts their protection requirements. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a permanent-temporary combined support system for the demolition of immovable cultural relics and its construction method are provided to solve the problem that existing support systems are prone to causing secondary disturbance to ancient buildings during the demolition, alteration and reconstruction process.

[0005] To achieve the above objectives, a combined permanent and temporary support system for the dismantling of immovable cultural relic structures is provided, comprising: The outer and inner sides of the outer wall of the immovable cultural relic structure are respectively provided with the surrounding beams. The surrounding beams are arranged along the circumferential direction of the immovable cultural relic structure, and the two surrounding beams on the inner and outer sides of the outer wall are connected by tie members. An angle brace, wherein the angle brace supports the corner of the beam connected to the inner side of the outer wall; The support frame includes multiple support columns and beams. The multiple support columns are erected inside the immovable cultural relic structure. The beams are connected to two adjacent support columns. The support columns on opposite sides of the support frame are attached to the inner side of the outer wall and connected to the inner side of the outer wall beam through connectors. The beams, the corner braces, and the beams permanently support the roof structure or newly constructed floor slab of the immovable cultural relic.

[0006] Furthermore, the tops of the surrounding beams, the corner braces, and the crossbeams are formed with supporting flanges that support the floor slab or roof.

[0007] Furthermore, the surrounding beam has a first through hole, the outer wall has a second through hole, and the tie member passes through the first through hole and the second through hole aligned with the first through hole.

[0008] Furthermore, the two ends of the tie member are formed with external threads, and the two ends of the tie member are screwed with threaded parts, and the two threaded parts are respectively pressed against the outer sides of the two surrounding beams on the inner and outer sides of the outer wall.

[0009] Furthermore, the column is a square column, the flange plate has a notch, the square column is embedded in the notch, and the connector includes a first flange and a second flange connected at an angle, the first flange is connected to the square column, and the second flange is connected to the supporting flange.

[0010] Furthermore, the exterior wall includes two long side walls arranged opposite each other and a short side wall connected between the ends of the two long side walls, and the corner brace is connected between the surrounding beams on the long side walls and the short side walls.

[0011] Furthermore, the ends of the two corner braces on the beam of the short side wall are connected together.

[0012] This invention provides a construction method for a permanent-temporary combined system for dismantling and supporting immovable cultural relic structures, comprising the following steps: Beams are installed on both the inner and outer sides of the outer wall of the immovable cultural relic structure, such that the beams are installed along the circumferential direction of the immovable cultural relic structure. Tie members are used to connect the two surrounding beams on the inner and outer sides of the outer wall; The corner brace is connected to the corner of the beam on the inner side of the outer wall; Multiple support columns are erected inside the immovable cultural relic structure, and beams are connected between two adjacent support columns to form a support frame. The support columns on opposite sides of the support frame are attached to the inner side of the outer wall and connected to the inner side of the outer wall beam through connectors. The outer wall beam, the corner brace and the crossbeam permanently support the roof structure or newly built floor of the immovable cultural relic. The internal structure of the immovable cultural relic was dismantled.

[0013] Furthermore, the internal structure includes existing frame columns, existing frame beams, and existing load-bearing interior walls.

[0014] The beneficial effect of this invention lies in the fact that the surrounding beam system in the permanent-temporary combination system for the demolition support of immovable cultural relic structures achieves overall constraint of the external wall. Surround beams are set on both the inner and outer sides of the external wall along the circumferential direction, and the surrounding beams on the inner and outer sides are connected through the wall by tie members, so that the external wall forms a "sandwich" stress state, which effectively constrains the out-of-plane deformation of the brick masonry external wall and prevents the external wall from overturning or collapsing during the demolition of the internal structure.

[0015] The corner bracing system of the permanent-temporary combined support system for the demolition of immovable cultural relics in this invention enhances the lateral resistance of corner sections. The corner bracing is connected to the corner of the inner beam of the outer wall. For rectangular immovable cultural relics structures, the corner bracing connects to the beam on the long side wall and the short side wall, with the ends of the two corner braces on the short side wall connected together to transfer shear force. This design significantly enhances the lateral stiffness of the structural corners, effectively resisting structural deformation under horizontal loads.

[0016] The temporary and permanent combined support system for the demolition of immovable cultural relics structures of this invention forms an integrated load-bearing system with the surrounding beams. The support columns on opposite sides of the support frame are attached to the inner side of the exterior wall and connected to the support flanges of the surrounding beams via connectors, thus forming an integrated load-bearing system with the surrounding beams, corner braces, and crossbeams. The support columns are square columns embedded in the notches of the support flanges. The first flange of the connector connects to the square column, and the second flange connects to the support flange, ensuring reliable node construction and a clear force transmission path.

[0017] The permanent-temporary combined support system for the dismantling of immovable cultural relics effectively reduces secondary disturbance to the cultural relics themselves. Existing temporary support systems often require numerous holes and perforations in the exterior walls to install connecting components, or use irreversible connection methods such as welding, causing varying degrees of damage to the cultural relics. This invention, through the close fit between the surrounding beams and the exterior walls, and the through-wall connection of tie rods, minimizes the number of perforations. Furthermore, the tie rods are detachably connected via bolts, avoiding irreversible damage and solving the problem of existing support systems easily causing secondary disturbance to ancient buildings.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 3 As shown, the present invention provides a permanent and temporary combined system for dismantling and supporting immovable cultural relic structures, including: a surrounding beam 1, corner braces 2, and a support frame 3.

[0025] Among them, the outer wall 41 of the immovable cultural relic structure 4 is provided with a surrounding beam 1 on both the inner and outer sides. The surrounding beam 1 is set along the circumferential direction of the immovable cultural relic structure 4. The two surrounding beams 1 on the inner and outer sides of the outer wall 41 are connected by tie members 11.

[0026] The corner brace 2 supports the corner of the beam 1 connected to the inner side of the outer wall 41.

[0027] In this embodiment, the immovable cultural relic structure is rectangular in shape. Accordingly, the outer wall 41 includes a long side wall 411 and a short side wall 412.

[0028] There are two long side walls 411. The two long side walls 411 are arranged opposite each other. There is a short side wall 412 between the ends of the two long side walls 411. The corner is formed between the long side walls 411 and the short side walls 412.

[0029] The corner brace 2 is connected between the beam 1 on the long side wall 411 and the short side wall 412.

[0030] In a preferred embodiment, the ends of the two corner braces 2 on the beam 1 on the short side wall 412 are connected together to provide shear force.

[0031] In this embodiment, the support frame 3 includes multiple support columns 31 and crossbeams 32.

[0032] Multiple support columns 31 are erected inside the immovable cultural relic structure 4. A crossbeam 32 connects two adjacent support columns 31.

[0033] In this embodiment, multiple support columns are arranged in a matrix.

[0034] The support columns 31 on opposite sides of the support frame 3 are attached to the inner side of the outer wall 41 and connected to the inner side of the outer beam 1 through the connector 33.

[0035] The roof structure or newly constructed floor slab that permanently supports the immovable cultural relic is a beam 1, corner brace 2, and crossbeam 32.

[0036] The top of the beam 1, the corner brace 2 and the crossbeam 32 forms a support flange 12 that supports the floor or roof.

[0037] See Figure 2 As shown. The surrounding beam 1 has a first through hole. The outer wall 41 has a second through hole. The tie member 11 passes through the first through hole and the second through hole aligned with the first through hole.

[0038] The two ends of the tie member 11 are formed with external threads. The two ends of the tie member 11 are screwed with threaded parts 13. The two threaded parts 13 press against the outer sides of the two surrounding beams 1 on the inner and outer sides of the outer wall 41, respectively.

[0039] Continue reading Figure 2 As shown, the column is a square column. The flange plate has a notch. The square column is fitted into the notch. The connector 33 includes a first flange 331 and a second flange 332 connected at an angle. The first flange 331 is connected to the square column. The second flange 332 is connected to the supporting flange 12.

[0040] This invention provides a construction method for a permanent-temporary combined system for dismantling and supporting immovable cultural relic structures, comprising the following steps: S1. Beams 1 are installed on both the inner and outer sides of the outer wall 41 of the immovable cultural relic structure 4, such that the beams 1 are installed along the circumferential direction of the immovable cultural relic structure 4.

[0041] Before construction, a comprehensive survey and record were made of the immovable cultural relic structure 4, including the masonry method and strength grade of the outer wall 41, and the location and dimensions of the existing frame columns 42, existing frame beams and existing load-bearing inner walls 43.

[0042] Based on the design drawings, measurements and layout were carried out on the construction site to determine the installation positions of the retaining beam 1, tie rod 11, corner brace 2, and support frame 3. At the same time, the site was leveled and cleaned, and construction materials such as channel steel, tie bolts, steel columns, and steel beams were prepared and inspected upon arrival at the site.

[0043] Beams 1 are installed on both the inner and outer sides of the outer wall 41 of the immovable cultural relic structure 4, so that the beams 1 are continuously installed along the circumferential direction of the immovable cultural relic structure 4. The beams 1 are made of channel steel (such as No. 20a channel steel, material 345B), and during installation, it should be ensured that the beams 1 are tightly attached to the surface of the outer wall 41. The top of the beams 1 forms a supporting flange 12, which is used to support the roof structure or newly constructed floor slabs.

[0044] S2, Connecting tie rods 11 between the two beams 1 on the inner and outer sides of the outer wall 41.

[0045] Drill second through holes at designed intervals (e.g., every 2000mm) on the exterior wall 41, and drill first through holes at corresponding positions on the inner and outer side beams 1. Insert tie members 11 (e.g., tie bolts) through the first through holes and the aligned second through holes, passing through the exterior wall 41. Tighten threaded fittings 13 (e.g., nuts) at both ends of the tie members 11, so that the two threaded fittings 13 press against the outer sides of the two side beams 1 on the inner and outer sides of the exterior wall 41, thus tightly connecting and fixing the inner and outer side beams 1.

[0046] S3. The corner brace 2 is connected to the corner of the beam 1 on the inner side of the outer wall 41.

[0047] The corner brace 2 is supported and connected to the corner of the surrounding beam 1 on the inner side of the outer wall 41. For the immovable cultural relic structure 4 with a rectangular plan, the corner brace 2 is connected between the surrounding beam 1 on the long side wall 411 and the short side wall 412.

[0048] Corner brace 2 is made of box-shaped steel components (200mm×200mm×6mm) and serves as horizontal corner support.

[0049] The ends of the two corner braces 2 on the beam 1 on the short side wall 412 are welded together to enhance the shear force transmission capacity.

[0050] S4. Multiple support columns 31 are erected inside the immovable cultural relic structure 4, and beams are connected between two adjacent support columns 31 to form a support frame 3. The support columns 31 on opposite sides of the support frame 3 are attached to the inner side of the outer wall 41 and connected to the inner side of the outer side beam 1 through connectors 33. The beam 1, corner braces 2 and crossbeams 32 permanently support the roof structure or newly built floor of the immovable cultural relic.

[0051] Multiple support columns 31 (steel columns, 300mm×300mm) are erected inside the immovable cultural relic structure 4, arranged in a matrix. Crossbeams 32 (steel beams, 250mm×400mm) are connected between adjacent support columns 31 to form a support frame 3.

[0052] The support columns 31 on opposite sides of the support frame 3 are attached to the inner side of the outer wall 41. The support columns 31 are square columns, and the support flanges 12 of the surrounding beam 1 have notches, into which the square columns are embedded. The support columns 31 are connected to the surrounding beam 1 by connectors 33 (angle irons): the first flange 331 of the connector 33 is connected to the square column, and the second flange 332 is connected to the support flange 12. This makes the surrounding beam 1, the corner braces 2, and the crossbeams 32 form an integrated load-bearing system, permanently supporting the roof structure of immovable cultural relics or the newly constructed floor slabs.

[0053] S5. Demolish the internal structure of immovable cultural relic structure 4.

[0054] After the support system is installed and passes inspection, the internal structure of the immovable cultural relic structure 4, including the existing frame columns 42, existing frame beams, and existing load-bearing interior walls 43, shall be dismantled. Dismantling shall be carried out layer by layer and section by section, from top to bottom, first horizontal components and then vertical components. During the dismantling process, the deformation and stability of the exterior walls 41 shall be monitored in real time to ensure construction safety. After the internal structure is dismantled, the surrounding beams 1, corner braces 2, and horizontal beams 32 shall continue to support the roof structure as a permanent support system or be used to support newly constructed floor slabs.

[0055] The internal structure includes existing frame columns 42, existing frame beams and existing load-bearing interior walls 43.

[0056] In this embodiment, the exterior wall is a brick masonry structure with a thickness of 500mm and a strength grade of MU15. The existing frame columns have a cross-sectional dimension of 300×300mm and a strength grade of C40.

[0057] The existing load-bearing interior walls are constructed using sintered shale bricks with a strength grade of MU15.

[0058] The perimeter beams are made of channel steel, size 20a, material 345B, and are load-bearing components. The tie rods on the perimeter beams are installed every 2000mm, and the tie rods penetrate the wall to connect and fix the inner and outer perimeter beams together.

[0059] The corner braces are box-shaped, with specifications of 200mm×200mm×6mm, and serve as horizontal corner supports, acting as stabilizing components. The ends of the two corner braces are welded together on the shorter side wall to provide shear force.

[0060] The supporting columns are steel columns with a cross-sectional specification of 300mm × 300mm, and are newly constructed structural steel columns. The beams are steel beams with a cross-sectional specification of 250mm × 400mm. The connectors are angle irons, which connect the new structure and the temporary supports to form a whole.

[0061] This invention enhances the structural stability and safety of the permanent-temporary combined support system for the demolition of immovable cultural relics. The permanent-temporary combined support system, composed of beams, corner braces, and support structures, provides reliable structural safety assurance for the internal demolition of immovable cultural relics.

[0062] The temporary and permanent combined support system for the demolition of immovable cultural relics structures in this invention achieves overall constraint of the exterior wall through the surrounding beam system. Surround beams are set on both the inner and outer sides of the exterior wall in the circumferential direction, and the inner and outer side beams are connected through the wall by tie rods (tie bolts), so that the exterior wall forms a "sandwich" stress state, which effectively constrains the out-of-plane deformation of the brick masonry exterior wall and prevents the exterior wall from overturning or collapsing during the demolition of the internal structure.

[0063] The corner bracing system of the permanent-temporary combined support system for the demolition of immovable cultural relics in this invention enhances the lateral resistance of corner sections. The corner bracing is connected to the corner of the inner beam of the outer wall. For rectangular immovable cultural relics structures, the corner bracing connects to the beam on the long side wall and the short side wall, with the ends of the two corner braces on the short side wall connected together to transfer shear force. This design significantly enhances the lateral stiffness of the structural corners, effectively resisting structural deformation under horizontal loads.

[0064] The temporary and permanent combined support system for the demolition of immovable cultural relics structures of this invention forms an integrated load-bearing system with the surrounding beams. The support columns on opposite sides of the support frame are attached to the inner side of the exterior wall and connected to the support flanges of the surrounding beams via connectors (angle irons), thus forming an integrated load-bearing system with the surrounding beams, corner braces, and crossbeams. The support columns are square columns embedded in the notches of the support flanges. The first flange of the connector connects to the square column, and the second flange connects to the support flange, ensuring reliable node construction and a clear force transmission path.

[0065] The permanent-temporary combined system for dismantling and supporting immovable cultural relic structures in this invention fully implements the principles of "minimal intervention" and "reversibility" in cultural relic protection: The permanent-temporary combined support system for the dismantling of immovable cultural relics effectively reduces secondary disturbance to the cultural relics themselves. Existing temporary support systems often require numerous holes and perforations in the exterior walls to install connecting components, or use irreversible connection methods such as welding, causing varying degrees of damage to the cultural relics. This invention, through the close fit between the surrounding beams and the exterior walls, and the through-wall connection of tie rods, minimizes the number of perforations (only tie bolt holes need to be set according to the design spacing), and the tie rods are detachably connected by bolts, avoiding irreversible damage and solving the problem of existing support systems easily causing secondary disturbance to ancient buildings.

[0066] The permanent-temporary combined system for dismantling and supporting immovable cultural relics in this invention is a reversible construction method that protects the original state of the cultural relics. The surrounding beams are made of channel steel, the corner braces are made of box-type steel components, and the support frame consists of steel columns and beams. All components are connected by bolts or detachable connectors. The construction process does not involve irreversible operations such as welding on the cultural relic itself. If restoration or adjustment is required, all components can be removed, maximizing the protection of the original state and historical appearance of the cultural relic.

[0067] The permanent-temporary combined support system for the demolition of immovable cultural relics structures of this invention allows for precise and controllable positioning of perforations in the exterior wall. A first perforation is provided in the surrounding beam, and a second perforation is provided in the exterior wall. Tie members are inserted into the first and aligned second perforations. By pre-setting the perforation positions on the surrounding beam, the position and diameter of the perforations on the exterior wall can be precisely controlled, avoiding additional damage to the wall caused by arbitrary perforations.

[0068] The temporary-permanent structure support system for the dismantling of immovable cultural relics of this invention achieves an organic combination of temporary support and permanent structure, and has significant economic benefits: The present invention provides a permanent-temporary combined support system for the demolition of immovable cultural relics, avoiding the duplication of support system construction. Beams, corner braces, and crossbeams permanently support the roof structure or newly constructed floor slabs of the immovable cultural relic. After the internal structure is demolished, the beams, corner braces, and crossbeams directly serve as components of the new structure, eliminating the need for demolition and reconstruction, thus avoiding the repetitive construction of temporary support systems in traditional construction methods that involve "erection-demolition-re-erection."

[0069] The permanent-temporary combined support system for the demolition of immovable cultural relic structures in this invention saves material and labor costs. The supporting flanges formed by the tops of the surrounding beams, corner braces, and crossbeams can directly support the floor slabs or roof, reducing the amount of formwork work required for new floor slabs. The supporting columns are permanently retained as steel columns in the new structure, and the crossbeams are permanently used as steel beams in the new structure, achieving "dual use of one item" and significantly saving steel consumption and construction labor costs.

[0070] The permanent-temporary combined support system for the dismantling of immovable cultural relic structures in this invention shortens the overall construction period. Since there is no need to rebuild a permanent support system after the internal structure is dismantled, nor is it necessary to dismantle temporary supports, the construction process is simplified, and the overall construction period is significantly shortened.

[0071] The construction process of the permanent-temporary combined system for dismantling and supporting immovable cultural relic structures according to the present invention is safe and controllable.

[0072] The temporary-permanent combined support system for the demolition of immovable cultural relics structures in this invention ensures safety by prioritizing support before demolition. The construction method strictly follows the sequence of "installing the surrounding beams → connecting the tie rods → installing the corner braces → erecting the support frame and connecting the surrounding beams → finally demolishing the internal structure." Before the demolition of the internal structure (existing frame columns, existing frame beams, and existing load-bearing interior walls), the complete external wall reinforcement support system is already in place and forms a unified load-bearing structure, ensuring that the external wall remains under control throughout the demolition process.

[0073] The components of the permanent-temporary combined support system for the demolition of immovable cultural relics structures in this invention work collaboratively and transmit forces clearly. The surrounding beams constrain the out-of-plane deformation of the exterior walls, the corner braces enhance the lateral resistance of the corners, and the support frame bears the vertical load and transfers the load to the surrounding beams and foundation through connectors. The three work collaboratively, and the force path is clear and well-defined.

[0074] The permanent-temporary combined support system for the demolition of immovable cultural relics structures of the present invention forms a permanent-temporary combined support system with minimal intervention to the cultural relic body, reversible construction, structural safety and reliability, and economic efficiency by setting up surrounding beams on both the inner and outer sides of the outer wall of the immovable cultural relic structure, setting corner braces at the corners, and erecting support frames inside and connecting them with the surrounding beams to form an integral whole. It effectively solves the technical problem of ensuring the stability of the outer wall during the construction process of "preserving the outer wall and demolishing and rebuilding the internal structure as a whole" for immovable cultural relics.

[0075] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
