Description

Technical Field

[0001] This invention relates to the field of modern building preservation, and in particular to a seamless modern wall support system and support construction method. Background Technology

[0002] The first paper focuses on the construction context, traditional construction techniques, and historical value of the "Minhang Street," a landmark street project from 1959, and the second paper, "A Multi-Scale Study of Environmental Behavior in Shanghai Lujiazui Workers' New Village," uses the living heritage of Shanghai Lujiazui Workers' New Village as a research sample. It analyzes the evolution of residential space, residents' autonomous renovation behavior, and the long-term survival mechanism of the community through multi-scale environmental behavior analysis. Both papers take Shanghai's brick-concrete modern workers' housing as their core research object, jointly demonstrating that the current work on the renewal and protection of such modern living heritage has significant shortcomings in its technical system. The core contradictions are concentrated in three key technical challenges: the lack of technology for the non-destructive protection of historical walls, the vulnerability of traditional support structures to the wall structure itself, and the insufficient compatibility of the support system with the historical streetscape.

[0003] There is a lack of dedicated non-destructive protection technology for modern brick and concrete walls, and multi-dimensional activities continue to cause irreversible damage to the original historical structure of the walls; Existing urban renewal projects have not established a layered protection process suitable for the low-grade mortar and thin-plastered simple brick-concrete walls built in the 1950s and 1960s. Multiple human activities continue to erode the original materials, masonry texture and historical structural information of the walls, and there is no supporting minimally invasive repair technology.

[0004] During the construction period, the inherent wall defects are compounded by extensive surface repairs, which permanently destroy the original historical information of the wall. According to historical records, this street in Minhang District was built in a rushed 78-day construction period. The original exterior plaster layer inherently suffered from defects such as hollowness, cracking, and peeling. The roof's waterproofing structure failed, leading to continuous water seepage. Over time, water seeped into the walls, causing efflorescence and large-scale peeling of the plaster. Subsequent repairs only involved simple surface coatings, failing to implement targeted wall protection measures such as base reinforcement, seepage prevention, and layered texture restoration. Multiple layers of repair paint and mortar covered the original brickwork and historical plaster layer, permanently destroying irreplaceable historical information such as the wall construction techniques and original finishes.

[0005] The supplement to "Environmental Behavior Study of Workers' New Village in Lujiazui Subdistrict, Shanghai under Multiple Scales" states that a large number of non-apartment-style residences with internal corridors built in the 1950s and 1960s in Lujiazui Workers' New Village used simple brick-concrete original walls. When the government led the renovation projects such as adding floors and converting flat buildings to pitched roofs, the load on the upper part was directly increased without verifying the load-bearing capacity of the walls. Holes were arbitrarily drilled in the walls to lay kitchen and bathroom pipes, and large areas of the original historical plaster layer on the exterior walls were removed and replaced with modern surface layers. The original masonry texture and plaster texture of the era were completely destroyed and could not be restored.

[0006] Residents' spontaneous and disorderly renovations simultaneously damage the structural stability of the walls and the original facade of the buildings. Based on the findings of an on-site survey of the Lujiazui Workers' New Village, it was discovered that ground-floor residents had enclosed their courtyards, restructured their interior spaces, and arbitrarily demolished or altered non-load-bearing partitions, creating new door and window openings in the exterior walls. Top-floor residents had illegally constructed attics and drilled holes in the exterior walls to fix temporary support components, directly causing brickwork cracks and leaving numerous permanent holes in the walls. When residents installed security windows, awnings, and air conditioner brackets themselves, expansion bolts pierced through the walls, creating through holes that allowed rainwater to seep into the masonry, exacerbating wall weathering and hollowing. Furthermore, residents replaced the exterior wall finishes themselves, using modern industrial paint to completely cover the original facade colors, utterly severing the unified and original visual appearance of the modern architecture.

[0007] Urban renewal projects prioritize improving residential functions while neglecting the preservation of the original walls, lacking specialized minimally invasive construction techniques for heritage-related walls. Both documents consistently confirm that current renovation and upgrading of workers' housing focuses on improving living facilities, without developing specific protection and construction standards for thin-walled brick-concrete walls. During the renovation phase, the original wall surfaces are directly and violently removed using machinery, without applying specialized heritage protection techniques such as gentle paint removal and non-destructive minimally invasive reinforcement. Pipeline trenching and door / window replacement are carried out by roughly cutting into the walls, damaging the original structural layers. The industry lacks a complete set of specialized technical solutions integrating wall reinforcement, waterproofing, moisture-proofing, and restoration of historical textures. All repair procedures are based on ordinary commercial housing construction standards, which are severely mismatched with the protection needs of fragile modern walls.

[0008] Traditional structural support and temporary construction support devices have inherent technical defects, which simultaneously damage the wall structure and the overall historical appearance of the block. The conventional support structures used in the reinforcement and renovation of modern buildings generally have inherent technical shortcomings, such as large body volume, exposed and unobstructed facade, low degree of freedom in height adjustment, and inability to adapt to the integrated coverage of architectural style. These shortcomings permanently damage the style and pattern of modern blocks from three aspects: permanent reinforcement support, temporary construction support, and changes in spatial scale.

[0009] Permanent reinforcement and support of exposed steel components disrupt the continuous historical facade along the street. The brick-and-mortar walls of the buildings along Minhang Street and the workers' new residential areas in Lujiazui generally suffer from settlement and structural cracking, posing safety hazards. Traditional reinforcement methods directly install exposed steel supports, diagonal steel frames, and reinforcement clamps on the outer side of the walls. These exposed components directly disrupt the iconic, unified, harmonious, and staggered continuous facade composition of Minhang Street. Conventional support components lack stylistic design coordination; their size, color, and placement do not match the modern architectural style of the 1950s and 60s, creating a strong visual conflict between the modern steel structure and the original architectural style. Furthermore, the installation of support requires the removal of large areas of the original wall surface, and after reinforcement, only simple touch-up painting is applied, resulting in mottled and messy repair marks on the wall surface, further damaging the integrity of the wall facade.

[0010] The temporary construction support lacked any supporting structure to conceal the weather conditions, and construction damage was permanently left on the wall. When renovation and addition projects are carried out on the linear, continuous streets along the Minhang district and the concentrated Lujiazui workers' new village, scaffolding, temporary bracing, and foundation pit support are directly attached to the exterior walls. Construction bumps and impacts easily cause damage to the plaster and brickwork. Traditional temporary supports rely on drilling and welding to fix them to the wall surface. After completion, only simple mortar is used to fill the holes, leaving dense repair scars on the wall surface and irreversibly destroying the historical texture of the wall. The continuous deployment of exposed temporary supports completely breaks the complete and continuous street interface, and there are no corresponding wall texture restoration and style restoration processes, resulting in permanent damage to the living style of modern blocks.

[0011] Traditional structural supports encroach on the original space and alter the landscape of modern urban planning. The core planning features of Minhang Street are a wide street with a building height three times that of its buildings, setbacked corner plazas, and a layered streetscape. Traditional methods of reinforcing dilapidated buildings often involve thickening the exterior walls and adding shear walls for support. However, these support structures encroach on the original building setbacks and street-side green spaces, compressing the original street width, altering the original width-to-height ratio of the street, and disrupting the original streetscape of "streets and blocks." In contrast, the original planning of Lujiazui Workers' New Village was for a low-density, balanced, and open neighborhood. External wall supports and outdoor reinforcement components encroach on building green spaces and public activity spaces, disrupting the balanced and open original spatial planning pattern of the workers' new village.

[0012] The lack of a top-level update mechanism and supporting technical system further amplifies the problem of damage to the appearance of walls and support works; The lack of a mechanism for identifying the heritage of modern workers' housing, and the absence of mandatory constraints for architectural style protection in the reinforcement and support structure. The Minhang Street and the Shanghai workers' new villages are not included in the lists of cultural relics protection units or historical buildings at any level. The renovation projects are implemented only according to the standards for municipal renovation of ordinary old residential buildings and are not subject to the regulations for the repair and management of historical buildings. Ordinary old renovation projects do not require the preparation of special wall protection plans or style-coordinated support design plans. Structural support and reinforcement projects only need to meet basic safety indicators and do not need to take into account the preservation of the original structure of historical walls and the integrity of the overall street style.

[0013] The update model focuses too much on functional renovation and lacks a sophisticated conservation and construction system adapted to modern heritage. The current renovation of old residential areas revolves around complete set renovation, building additions, and flat-to-slope conversions. Project funds and construction acceptance standards are all tilted towards improving living functions, without allocating special funds for the protection of walls without damage and the restoration of the original appearance. Construction units do not have a mandatory entry threshold for qualifications to repair modern historical buildings, and the crude construction techniques of general civil engineering are directly applied to the fragile and thin brick-concrete walls.

[0014] The lack of a balancing mechanism for living heritage has created a binary opposition between the needs of people's livelihood renovation and the protection of the architectural style of the walls. Lujiazui Workers' New Village is a living modern heritage site continuously inhabited. Residents have long had a need for wall renovation and space expansion, but current management methods rely solely on a "one-size-fits-all" approach of demolishing illegal structures, failing to provide alternative technological solutions that balance preservation and the needs of residents, such as minimally invasive wall renovations and concealed support systems. Traditional reinforcement methods only consider structural safety, failing to address both residents' daily needs and the preservation of historical walls and facades. This has created a long-standing conflict between preservation and residents' well-being, continuously exacerbating wall damage and the destruction of the village's historical character.

[0015] There is a complete lack of technologies for the repair and support of defects in modern thin-walled walls. Regarding the typical defects such as weathering, water seepage, and cracking of low-grade mortar and thin-plastered brick-concrete walls mentioned in the literature, the industry currently lacks mature and complete sets of specialized non-destructive repair processes. All current wall support and reinforcement schemes directly apply the design standards for thick-walled structures in modern commercial housing, which are not adapted to the characteristics of modern exterior walls with thin plastering, low masonry strength, and easy damage. Conventional rigid support actually squeezes and tears the fragile walls, accelerating the development of wall defects.

[0016] Common technical defects in existing general support structures; Looking at the field of wall protection and structural support for modern and contemporary buildings in China, the currently available support devices all suffer from four major technical shortcomings: First, the overall size of the support structure is enormous, with support components exposed on the street-facing facade, severely disrupting the original appearance of the neighborhood; second, the adaptability of the support height adjustment mechanism is poor, lacking flexibility in adjusting layered support and simultaneous reinforcement of weak areas in multiple locations; third, there is a lack of integrated contour-following shielding structures, making it impossible to achieve complete visual coverage of the metal support structure; fourth, there is no seamless shielding design matching modern and contemporary wall facades, making it impossible to achieve visual integration with the original building facade after support construction, and making it difficult to balance structural safety support with the preservation of historical features; and fifth, the support structure has a single function.

[0017] On June 24, 2025, a paper titled "Keywords: Technologies for modern wall support that do not affect the architectural style; (TIAB = ("historical building wall reinforcement" OR "heritage structure support" OR "non-intrusive support technology" OR "traditional building seismic retrofitting" OR "old city wallstabilization") )) AND (TIABC = ("wall support" OR "heritage protection" OR "non-intrusive" OR "historical building reinforcement" OR "lightweight structure" OR "aesthetic preservation") OR TIABC = ("minimally invasive reinforcement" OR "non-destructive construction" OR "low vibration" OR "concealed installation" OR "Rapid curing" OR "Minimally invasive reinforcement" OR "Non-destructive construction" OR "Low vibration" OR "Hidden installation" OR "Fast curing" OR TIABC = ("Aesthetically compatible" OR "Decorative reinforcement" OR "Visual integration" OR "Invisible reinforcement" OR "Aesthetically compatible" OR "Decorative reinforcement" OR "Historic compatibility") ORTIABC = ("Structural monitoring" OR "Smart support" OR "Embedded sensors" OR "Real-time feedback" OR "Automatic early warning" OR "Structural monitoring" OR "SmartUsing "reinforcement" OR "embedded sensor" OR "real-time feedback" OR "automatic alert") as keywords, and with the option to allow synonym expansion selected, a search was conducted in the China Patent Publication Database, but no relevant literature was found. Summary of the Invention

[0018] Purpose of the invention: To provide a more effective seamless modern wall support system and support construction method, the specific purpose of which is explained in the detailed implementation section for several substantial technical effects.

[0019] To achieve the above objectives, the present invention adopts the following technical solution: The seamless modern wall support system is characterized by comprising a small-footprint support structure arranged on the side of the wall. The small-area support structure includes a support base plate 2, on which a three-sided surrounding groove 3 is arranged. One or more three-sided enclosure-shaped column surfaces 13 can be stacked in sequence in the groove 3. The three-sided enclosure-shaped column surfaces 13 are pasted with the same visual pattern as modern walls 1. The supporting base plate 2 is fixed to the ground with bolts; The small-area support structure includes a vertical lifting column 5 and a vertical positioning column 4; the vertical lifting column 5 includes two sets of steel symmetrically arranged, with a groove between the two sets of steel, and the upper and lower ends of the two sets of steel are connected together, and the lower ends of the two sets of steel are integrally welded to the support base plate 2; it also includes a vertically movable fixing block 7 that can move up and down in the groove of the lifting column 5, the vertically movable fixing block 7 and the support diagonal rod 9 are integrally manufactured, and the end of the support diagonal rod 9 is provided with a wall support surface 11; The lifting and lowering mechanism of support diagonal brace 9 can be adjusted to the corresponding height. The lifting column 5 is provided with one or more vertically arranged adjustment holes 6. After the fixing bolt 10 passes through the adjustment hole 6 and the hole on the vertically movable fixing block 7, the other end passes through the lifting column 5 and is fixed by a nut. The end of the support diagonal rod 9 includes a positioning block 8, and the lifting hole 801 in the middle of the positioning block 8 is fitted onto the positioning column 4 and can be raised and lowered. Multiple positioning holes are arranged on the positioning column 4. After the positioning bolt 802 passes through the positioning hole of the positioning column 4 and the threaded hole of the positioning block 8, it can fix the positioning block 8 and the positioning column 4 relative to each other. The wall support surface 11 is pressed against the weak, protruding part of the wall surface; The main body of the small-area support structure, consisting of the supporting base plate 2, lifting column 5, positioning column 4, and supporting diagonal rod 9, is located in the three-enclosure contour column surface 13.

[0020] A further technical solution of the present invention is that the wall support surface 11 is integrally connected to the top support surface 12, and the top support surface 12 can be used to support the building roof when the supporting diagonal rod 9 moves to the uppermost position.

[0021] A further technical solution of the present invention is that, when used to support the roof of a building, the groove 3 is a four-sided groove, and the enclosure is a four-sided enclosure with a contoured column surface.

[0022] A further technical solution of the present invention is that the edge of the supporting base plate 2 is closely attached to the bottom of the modern wall 1.

[0023] A further technical solution of the present invention is that the three-walled contoured column surface 13 is made of plastic or wood-plastic composite material.

[0024] A further technical solution of the present invention is that the visual pattern is the same as that of the modern wall 1, which is printed after photographing the modern wall 1 and then pasted on the imitation column surface of the fence; so that the appearance can visually ignore the existence of the column; the supporting diagonal rod 9 and the wall support surface 11 both contain multiple sets and are arranged vertically.

[0025] A further technical solution of the present invention is that the seamless modern wall support system comprises multiple sets, and the multiple sets of seamless modern wall support systems work together for support; except for the three-wall conformal column surface 13, all other materials are metal and all adopt high-strength structural steel; the wall support surface 11 is covered with a layer of rubber to adapt to the unevenness of the modern wall 1.

[0026] A seamless modern wall support construction method, characterized by utilizing any one of the aforementioned seamless modern wall support integrated systems. It includes the following steps: Survey modern and contemporary walls 1, mark the protruding and weak areas of the wall surface, the bottom position of the wall that needs to be supported, and the support points on the top of the building, and determine the area for single or multiple sets of combined support. Clean up debris at the bottom of the wall and place the support base plate 2 tightly against the bottom of the modern wall 1. Use bolts to fasten the support base plate 2 to the ground. Mount positioning columns 4 and lifting columns 5 on the supporting base plate 2 to ensure that the two columns are vertical and without tilting, and calibrate the parallelism between the columns and the wall. Check that the multi-layer adjustment holes 6 on the lifting column 5 and the multiple sets of positioning holes 401 on the positioning column 4 are not blocked, and prepare the fixing bolts 10 and positioning bolts 802.

[0027] Take the integrated molded vertical moving and fixing block 7 and the supporting diagonal rod 9 assembly, and insert the vertical moving and fixing block 7 into the vertical groove of the lifting column 5; According to the height of the marked weak area of ​​the wall, slide the fixed block 7 up and down, drive the support diagonal rod 9 up and down, so that the end wall support surface 11 is aligned with the protruding weak position of the wall. The positioning block 8 is fitted onto the positioning column 4 through the central lifting hole 801 and rises and falls synchronously to match the height of the wall support surface 11. Once the height is reached, the fixing bolt 10 passes through the adjustment hole 6 of the lifting column 5 and the opening of the vertical moving fixing block 7, and the nut is tightened to fix the vertical moving fixing block 7; the positioning bolt 802 passes through the positioning hole 401 of the positioning column 4 and the threaded hole of the positioning block 8, locking the positioning block 8 to complete the height locking. Multiple sets of vertically arranged support diagonal rods 9 repeat the above lifting and locking steps in sequence to reinforce the weak wall surface of the modern wall 1 by layer compression; Fence contour column assembly: Three fence contour column surfaces 13 are stacked layer by layer in the three-sided surrounding groove 3 of the support base plate 2; the contour column surfaces are pasted with printed wall real shot pictures in advance, and the lifting column 5, positioning column 4, and supporting diagonal bar 9 are stored and covered as a whole to achieve visual tracelessness. Multiple support systems are arranged side by side to provide simultaneous support for long sections of modern walls, completing the pure wall surface protection operation.

[0028] A further technical solution of the present invention is that, Optional integrated support installation and adjustment for the top and wall surfaces can be implemented to achieve dual protection for both the wall and the top surface. The steps for foundation positioning, column installation, and wall support height calibration are the same as steps AK, ensuring that the wall support surface 11 fits the weak points of the wall. Adjust the support diagonal rod 9 upward to the uppermost stroke of the lifting column 5, so that the top support surface 12, which is integrally connected to the wall support surface 11, is raised to the bottom of the building. Fine-tune the height of the support diagonal rod 9 so that the top support surface 12 is completely in contact with the pressure point of the building's top surface. Tighten the fixing bolts 10 and positioning bolts 802 again to fix the double support positions of the wall and top surfaces. Multiple support units are deployed in coordination to simultaneously provide lateral compression protection for the wall and vertical load-bearing support for the building's roof.

[0029] Check that the rubber-coated wall support surface 11 is evenly attached to the wall and there is no local hard pressure damage to the wall; the top support surface 12 is evenly stressed and has no deviation. Confirm that all bolts are tightened in place, the contour fence is fully assembled, and its appearance is visually consistent with the modern wall. After the support period ends, first remove the three / four enclosure contour column surfaces 13, and then remove the positioning bolts 802 and fixing bolts 10 in sequence; Lower the support diagonal rod 9 to reduce the wall and top support surfaces, separating them from the wall and building top surface; remove the lifting column 5 and positioning column 4, loosen the ground bolts and remove the support base plate 2, completing the dismantling of the entire support structure.

[0030] A further technical solution of the present invention is that, Optionally, separate top protection can be provided, and the enclosure structure can be replaced: the three-sided groove (3) on the support base plate (2) can be replaced with a four-sided groove, and four enclosure-shaped columns can be stacked in the groove to completely wrap the entire metal support body; the overall structure is not close to the wall and is used to support the top surface.

[0031] The present invention, employing the above technical solution, offers the following advantages over existing technologies: This patent addresses the pain points of repairing old brick-concrete walls from the 1950s and 60s, pioneering a unique non-destructive support technology system and filling a technological gap in the industry. It utilizes rubber-coated flexible support and a layered adjustable diagonal bar structure, which can disperse compressive pressure, adapt to layered wall defects, and eliminate wall tearing and damage caused by rigid support. The equipment is anchored to the ground, requiring no wall drilling or chiseling throughout the process, resulting in damage-free assembly and disassembly, and preserving the original architectural texture. Simultaneously, an innovative contour-following concealing structure can completely accommodate metal support components, replicating the original wall appearance, eliminating visual conflicts, and protecting the overall streetscape. The device adopts a dual-column collaborative adjustment structure, supporting multi-point, layered, independent pressure-controlled support, adapting to different wall defect conditions. It features three support modes: wall surface, roof surface, and integrated wall-roof, offering wide adaptability. The equipment's small, integrated design occupies minimal space and does not occupy public space. The entire technology is equipped with standardized construction processes that take into account both heritage protection and the needs of residents for renovation, effectively solving the challenges of matching safety, appearance, and people's livelihood in the renovation of old buildings. Attached Figure Description

[0032] To further illustrate the present invention, the following description is provided in conjunction with the accompanying drawings: Figure 1 The invention provides a structural diagram of the structure without enclosure after support. Figure 2 This is a partial structural diagram of the invention; Figure 3 A partial structural diagram of another part of the invention; Figure 4 A structural diagram showing the structure that was supported and enclosed after the invention was completed; Among them: 1. Modern wall structure; 2. Support base plate; 3. Groove; 4. Positioning column; 5. Lifting column; 6. Adjustment hole; 7. Up and down moving fixing block; 8. Positioning block; 9. Supporting diagonal rod; 10. Fixing bolt; 11. Wall support surface; 12. Top support surface; 13. Three-sided enclosure contoured column surface; 14. Insertion edge; 801. Lifting hole; 802. Positioning bolt; 401. Positioning hole.

[0033] Figure 1 clearly shows that: the support base plate 2 is fixed to the bottom of the near-modern wall 1; the lifting column 5 and the positioning column 4 are welded to the top of the support base plate 2; the vertical moving fixing block 7 and the support diagonal rod 9 are integrated and clamped in the vertical groove of the lifting column 5; the positioning block 8 is sleeved on the positioning column 4; the front wall support surface 11 of the support diagonal rod 9 is aligned with the weak protrusion of the wall; the top support surface 12 is set up simultaneously; the entire set of metal support components is completely exposed and without the three-walled contour column surface 13; the stable force-bearing mechanism is formed by the double column coordinated lifting and locking structure combined with the layered support diagonal rods; the bare support layout of the wall side support is realized; the complete assembly relationship and force support logic of the entire small-area support structure in the state without the obstruction of the enclosure are intuitively shown.

[0034] As can be clearly seen in Figure 2, the positioning block 8 has a lifting hole 801 in the middle, which can be sleeved on the outside of the positioning column 4 and slide vertically. The positioning column 4 has multiple sets of positioning holes 401. The positioning bolt 802 can pass through the positioning hole 401 and the threaded hole of the positioning block 8 to achieve height locking. The lifting hole 801 and the positioning bolt 802 cooperate with each other to form a limiting locking mechanism on the side of the positioning column, which is matched with the fixing bolt locking structure on the side of the lifting column. Together, they complete the bidirectional fixed force after the support diagonal bar 9 is lifted, providing double locking guarantee for layered support.

[0035] As shown in Figure 3, multiple sets of vertically arranged positioning holes 401 are evenly distributed on the vertical positioning column 4. These holes are regularly spaced and can accommodate the locking requirements of positioning blocks 8 at different heights. The positioning holes 401 serve as channels for the positioning bolts 802, corresponding one-to-one with the adjustment holes 6 on the lifting column 5, forming a multi-point height adjustment reference structure for the double columns. This allows the support diagonal rod 9 to be locked at any height of the wall defect, constructing a layered and adjustable support force reference. The holes other than the bolt holes are preferably elongated to accommodate fine-tuning.

[0036] As shown in Figure 4, it can be clearly seen that three layers of enclosure-shaped column surfaces 13 are stacked in the groove 3 surrounding the three sides of the supporting base plate 2. The enclosure-shaped column surfaces completely enclose the entire metal support body of the internal supporting base plate 2, lifting column 5, positioning column 4, and supporting diagonal rod 9. The surface of the enclosure-shaped column surfaces 13 replicates the visual pattern of the modern wall 1. The wall support surface 11 and the top support surface 12 are hidden inside the enclosure, with only the outer side presenting a visual effect consistent with the original wall. The internal double column layered support structure continuously forms a stable compression support for the wall, and the external enclosure achieves visual traceless concealment, integrating a dual structural system of non-destructive support and style protection.

Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0040] The choice of materials used in an invention does not limit the scope of protection. Example

[0041] Solution: Seamless Modern Wall Support System, characterized in that the system includes a small-footprint support structure arranged on the side of the wall; the small-footprint support structure includes a support base plate 2, on which a three-sided surrounding groove 3 is arranged, in which one or more three-sided enclosure-shaped column surfaces 13 can be stacked sequentially, the three-sided enclosure-shaped column surfaces 13 using the same visual pattern as the modern wall 1; the support base plate 2 is fixed to the ground by bolts; the small-footprint support structure includes a vertical lifting column 5 and a vertical positioning column 4; the vertical lifting column 5 includes two sets of steel symmetrically arranged, with a groove between the two sets of steel, the upper and lower ends of the two sets of steel are connected, and the lower ends of the two sets of steel are integrally welded to the support base plate 2; it also includes a vertically movable fixing block 7 that can move up and down in the groove of the lifting column 5, the vertically movable fixing block 7 and the support diagonal rod 9 are integrally manufactured, and the end of the support diagonal rod 9 is provided with a wall support surface 11; the support diagonal rod 9 The lifting mechanism can be adjusted to the corresponding height; the lifting column 5 is provided with one or more vertically arranged adjustment holes 6. After the fixing bolt 10 passes through the adjustment hole 6 and the hole on the vertically movable fixing block 7, the other end passes through the lifting column 5 and is fixed by a nut; the end of the supporting diagonal rod 9 includes a positioning block 8. The lifting hole 801 in the middle of the positioning block 8 fits on the positioning column 4 and can be raised and lowered; multiple positioning holes are arranged on the positioning column 4. After the positioning bolt 802 passes through the positioning hole of the positioning column 4 and the threaded hole of the positioning block 8, the positioning block 8 and the positioning column 4 can be fixed relative to each other; the wall support surface 11 is pressed against the weak protrusion of the wall surface; the main body of the small-area support structure composed of the supporting base plate 2, the lifting column 5, the positioning column 4, and the supporting diagonal rod 9 is located in the three-enclosure imitation column surface 13.

[0042] Compared to the shortcomings of existing technologies, modern brick-concrete walls lack a dedicated non-destructive support system. General rigid supports suffer from hard contact, compression, thin plastering, and low strength, leading to easy tearing of masonry; exposed steel components on the facade damage historical appearance; traditional supports involve drilling and anchoring, permanently damaging the wall; conventional supports are bulky and encroach on public street space; and traditional supports have low flexibility in lifting and adjusting, failing to provide layered reinforcement and addressing multiple defects. This patent innovatively and non-obviously integrates a ground-anchored support base plate 2, a double-column coordinated lifting and locking mechanism, layered adjustable support diagonal rods 9, and a three-sided surrounding groove 3 with a three-walled contoured column surface 13 to form a small-footprint support structure. Through construction step B, the support base plate 2 is anchored only to the ground without contacting the modern wall 1, completely avoiding permanent damage to the original texture caused by wall drilling and welding. Through construction steps F, G, and H, the vertically movable fixing block 7 slides along the vertical groove of the lifting column 5, and the positioning block 8 rises and falls synchronously along the positioning column 4 and is independently locked. Multiple sets of support diagonal rods 9... Layered flexible compression is applied to weak points at different heights of the wall to solve the problem of rigid compression of the wall under single-point large loads in traditional support. Then, through construction step J, three enclosures and imitation column surfaces 13 are stacked in the groove 3 to completely accommodate all metal support components. Combined with a finish that replicates the visual appearance of the wall, the facade is visually seamless. At the same time, the entire support unit is laid close to the bottom of the wall, with a very small footprint, and will not occupy the green space along the street or the street setback. It simultaneously solves multiple industry defects such as support damaging the wall, destroying the landscape, occupying a large space, and poor layered adjustment ability. It is equipped with a standardized construction process for surveying, installation, and shielding, and is suitable for the non-destructive support needs of modern walls made of low-grade mortar thin-walled bricks from the 1950s and 1960s. Example

[0043] Solution: The wall support surface 11 is integrated with the top support surface 12. When the supporting diagonal rod 9 moves to the uppermost position, the top support surface 12 can be used to support the building roof.

[0044] Compared to the shortcomings of existing technologies, commercially available support systems only provide single-sided wall reinforcement and lack an integrated wall-top support structure. Repair projects require separate roof support installations, and the stacking of two sets of devices further occupies space, with exposed components damaging the original facade of the street. This patent innovatively and non-obviously integrates the roof support surface 12 and the wall support surface 11 into a single unit at the end of the support diagonal rod 9. By adjusting the support diagonal rod 9 upwards to the uppermost stroke of the lifting column 5 in construction step M, the roof support surface 12 can be raised to fit against the building's base, forming a vertical bearing support without the need for additional independent support components. It utilizes the existing lifting and locking adjustment system, and through construction step N... The system uses 10 locking bolts and 802 positioning bolts to simultaneously lock the dual stress positions of the wall's lateral support and the top vertical support. One set of equipment can simultaneously complete the reinforcement of wall defects and the protection of the building's roof load-bearing capacity, avoiding the problems of multiple sets of support components being superimposed and exposed, encroaching on public street space, and disrupting the historical facade style. It achieves synchronous integrated protection of the wall and roof, enriching the adaptability of support conditions. Example

[0045] For the proposed solution: when used to support the building's roof, groove 3 is a four-sided groove, and the enclosure is a four-sided enclosure with a contoured column surface.

[0046] In contrast to existing technologies, when implementing integrated wall and roof support, the original three-sided enclosure cannot completely cover the supporting components extending to the top, leaving the metal steel frame partially exposed, which still disrupts the continuous facade composition of modern buildings along the street. This patent innovatively and non-obviously replaces the original three-sided surrounding groove 3 of the support base plate 2 with a four-sided groove, and the matching stackable four-sided enclosure with contoured column surfaces completely covers the entire metal support body. When performing the integrated wall and roof support process from construction steps L to R, the four-sided enclosure can completely cover all steel components such as the lifting column 5, positioning column 4, supporting diagonal rod 9, and top support surface 12 from all sides. No matter what height the supporting diagonal rod 9 is raised to or the top support surface 12 is under pressure, there is no exposed steel frame on the outside, maintaining the integrity and unity of the original architectural style of the block throughout the process, and eliminating the visual discontinuity caused by the partial exposure of steel structure in the wall and roof support condition. Example

[0047] Solution: The edge of the supporting base plate 2 is close to the bottom of the modern wall 1.

[0048] Compared to the shortcomings of existing technologies, traditional external support bases are placed far from the wall, with diagonal bracing components extending outwards significantly, occupying a large amount of street and green space, and disrupting the original spatial planning texture of workers' new villages and modern buildings along the street. This patent innovatively and non-obviously arranges the support base plate 2 with its edge close to the bottom of the modern wall 1 as the load-bearing base of the entire support structure. Based on construction step B, the support base plate 2 is fixed to the ground at the bottom of the wall, and all the lifting columns 5 and positioning columns 4 are vertically concentrated in a very small area on the side of the wall, without large diagonal frame structures extending outwards, greatly reducing the footprint of the support unit. When multiple support systems are arranged side by side to support long sections of the wall according to construction step K, each unit is compactly arranged along the wall, without compressing the street passage width or disrupting the original low-density and transparent spatial scale of the neighborhood, making it suitable for the renovation work conditions of small sites in existing modern historical blocks. Example

[0049] Solution: The three-sided enclosure contoured column surface 13 is made of plastic or wood-plastic composite material.

[0050] Compared to the shortcomings of existing technologies, metal shielding fences are too heavy, difficult to stack and assemble, prone to paint peeling and deformation after rusting, and difficult to match the visual appearance of modern building facades in the long term. In addition, the transportation and dismantling labor costs are high. This patent innovatively and non-obviously uses lightweight plastic or wood-plastic composite materials to prepare the three-sided fence contoured column surface 13. The material has low self-weight, and the construction steps J (stacking) and the subsequent construction steps R (dismantling) can be completed by a single person, reducing the consumption of on-site construction labor. Plastic and wood-plastic composites have the characteristics of moisture resistance, rust resistance, and deformation and crack resistance. The interior surface pattern will not be damaged by the corrosion of components during the long-term support period, and can stably maintain the same appearance effect as the modern wall 1. At the same time, the material is easy to cut and shape, and can be adapted to different height support bodies to flexibly adjust the number of fence stacking layers, taking into account both shielding function and on-site construction convenience. Example

[0051] Solution: The visual pattern is the same as that of the modern wall 1. It is made by taking a picture of the modern wall 1 and printing it out, and then pasting it on the imitation column surface of the fence; so that the appearance can visually ignore the existence of the column; the supporting diagonal rod 9 and the wall support surface 11 both contain multiple sets, and are arranged vertically.

[0052] Compared to the shortcomings of existing technologies, traditional support systems lack a matching architectural style shielding structure, resulting in a visual conflict between the exposed steel frame and the original modern architectural style. Furthermore, the support only applies pressure at a single point, failing to address the characteristics of layered hollowing and multiple cracks in the wall. This patent innovatively and non-obviously employs a real-life photograph of the wall surface printed onto the simulated column surface of the enclosure, along with multiple sets of vertically and horizontally arranged support diagonal braces 9 and wall support surfaces 11. Before construction, the original appearance of the corresponding modern wall 1 is photographed and printed. After the enclosure is assembled in construction step J, the simulated column appearance blends seamlessly with the surrounding wall, visually concealing all internal metal support structures and preserving the continuous historical facade composition along the street. In construction step I, each set of support diagonal braces 9 is independently raised, lowered, and locked. Each set of wall support surfaces 11 can be individually aligned with different heights of protruding weak areas to apply pressure layer by layer, flexibly dispersing the support load and avoiding large-area rigid compression damage to low-strength thin-plastered walls. This simultaneously solves the two major pain points of architectural style damage and layered reinforcement of multiple wall defects. Example

[0053] Solution: The seamless modern wall support system consists of multiple sets, which work together for support; except for the three-wall conformal column surface 13, all other materials are metal and all use high-strength structural steel; the wall support surface 11 is covered with a layer of rubber to adapt to the unevenness of the modern wall 1.

[0054] Compared to the shortcomings of existing technologies, the reinforcement range of a single support unit is limited. The renovation of continuous worker's new villages and long stretches of modern walls along streets requires a large number of scattered support components. Rigid metal support surfaces directly contacting the wall are prone to cracking, scratching thin plaster and brickwork, and exacerbating wall efflorescence damage. Ordinary steel supports have insufficient load-bearing capacity, and layered support is prone to deformation and failure under long-term pressure. This patent innovatively and non-obviously adopts a multi-stage design: multiple support units are deployed together, high-strength structural steel is used for the metal main body, and a flexible rubber coating layer is added to the wall support surface 11. Following construction steps K, multiple units are arranged in parallel for coordinated support, with each group independently adjusting its support height and pressure. This allows for the one-time completion of segmented and layered reinforcement of long, continuous walls, suitable for large-scale concentrated renovation projects of modern heritage sites. High-strength structural steel is used to construct the support base plate 2, lifting columns 5, positioning columns 4, and support diagonal rods 9, ensuring the stability of the multi-layered support structure under long-term pressure and preventing bending and deformation. The rubber coating layer connects the wall support surface 11 with the modern wall 1. Flexible contact disperses local pressure. Construction step P: Check that the rubber layer is evenly attached to the wall surface to prevent plaster cracking and brick damage caused by hard metal contact, achieving dual protection of structural load-bearing capacity and non-destructive wall protection.

[0055] I. Defect 1: There is a lack of a dedicated non-destructive protection technology system for modern brick-concrete walls. There is no layered protection process suitable for the low-grade mortar and thin-plastered simple brick-concrete walls of the 1950s and 1960s. Conventional rigid supports are easily squeezed and torn by the fragile walls, causing irreversible damage to the original structure of the walls. Compared to the shortcomings of existing technologies, modern brick-concrete walls lack a dedicated non-destructive support system. General rigid supports, which involve hard contact and compression, result in thin plaster and low-strength walls that are prone to tearing, damaging the original plaster and masonry texture. This patent innovatively and non-obviously sets up a wall support surface 11 with a rubber coating layer, combined with layered adjustable support diagonal rods 9, to form a flexible layered support structure. It is equipped with a complete traceless support construction process to achieve minimally invasive and non-destructive reinforcement of the wall.

[0056] Structural component adaptation design: The surface of the wall support 11 is covered with a rubber layer, which makes flexible contact with the modern wall 1, dispersing the support compression force and avoiding direct hard pressure from rigid metal components to scratch, crack thin plaster, and low-strength brick masonry, thus eliminating the problems of local wall damage and efflorescence; the support diagonal rods 9 are set in multiple sets and arranged in layers, which can provide layered and individual support for multiple protruding weak points on the wall, matching the distribution characteristics of layered hollowing, cracking, and local defects in brick-concrete walls, achieving layered protection rather than overall large-area rigid compression.

[0057] The adjustment mechanism enables controllable pressure application: the lifting column 5 has multiple adjustment holes 6, and the vertically movable fixing block 7 can slide freely along the vertical groove of the lifting column 5. In conjunction with the positioning column 4, positioning block 8, lifting hole 801, and positioning bolt 802, it can precisely lock any height. In construction step FH, the wall support surface 11 can be precisely aligned with the wall defect area, and the support compression force can be manually and controllably adjusted. This avoids the problem of traditional support compressing fragile walls with a large load at one time. In construction step I, each set of support diagonal rods 9 is locked in layers to reinforce the wall in layers, which is suitable for the low load-bearing capacity of thin-walled brick-concrete walls.

[0058] The construction process is completely non-destructive: In construction step B, the supporting base plate 2 is fixed tightly to the bottom of the wall and ground. There is no need to drill holes, weld, or remove large areas of the original surface layer on the modern wall 1. This completely avoids the defects of traditional support chiseling, drilling holes and leaving permanent holes, and repairing scars that damage the historical texture. In the demolition stage, steps 18-19, the supporting diagonal rod 9 is first lowered to detach the wall support surface 11 from the wall. Then all components are dismantled. There are no wall damage procedures throughout the process, and the original masonry texture and plaster texture of the era are completely preserved.

[0059] 2. Defect 2: The traditional permanent reinforcement / temporary support with exposed external steel components disrupts the continuous historical facade along the street, creating a visual conflict between the steel structure and the original building, and lacking a structural element to complement and shield the architectural style. Compared to the shortcomings of existing technologies, where all supporting metal steel components are exposed without a matching shielding structure, and where the modern steel frame clashes with the facade of modern buildings, disrupting the continuous historical facade composition along the street, this patent innovatively and non-obviously designs a groove 3 and a stackable three-walled contoured column 13 as an integrated visual shielding system, which conceals and hides the entire metal support structure, achieving visual invisibility of the support structure.

[0060] The basic structure of the shielding carrier: The support base plate 2 is provided with three-sided surrounding grooves 3. The three-sided enclosure contour column surface 13 can be stacked layer by layer in the grooves 3. The main body of the entire small-footprint support structure, consisting of the support base plate 2, lifting column 5, positioning column 4, and support diagonal bar 9, is completely housed inside the three-sided enclosure contour column surface 13, completely shielding the metal steel frame, bolts and other components from the outside. There is no problem of exposed steel supports or diagonal braces damaging the street facade.

[0061] Style matching and contour design: Three-wall contoured column surface 13, surface pasted with modern wall 1, real shot printed visual pattern, construction steps J, prefabricated contoured cladding, after concealment, the appearance is visually unified with the original wall, eliminating the visual separation between the metal support and the architectural style of the 1950s-1960s, and completely preserving the continuous and soft street facade composition of Minhang Street and Workers' New Village.

[0062] Upgraded shielding for different working conditions: When integrated support for walls and roof is required, the three-sided groove 3 can be replaced with a four-sided groove, which, together with the four-sided enclosure contoured column surface, can completely wrap all metal components; in the case of separate roof protection, the four-sided enclosure structure can be replaced, and the main body can be fully shielded regardless of the support mode, maintaining the integrity of the original facade of the block throughout the process.

[0063] 3. Defect 3: Traditional support installation requires large-area removal of the wall surface layer and drilling holes in the wall for fixing, leaving dense repair scars after completion, and permanently losing the historical texture of the wall. Compared to the shortcomings of existing technologies, traditional support relies on drilling and welding to fix the wall, which can damage the plaster layer during construction and irreversibly destroy the original texture of the wall after demolition due to holes and repair marks. This patent innovatively and non-obviously adopts a ground-anchored support base plate 2 as the load-bearing base of the entire support structure, without drilling or welding connection points with the modern wall 1 throughout the entire process.

[0064] Fixing method detached from the wall: The supporting base plate 2 is individually fixed to the ground with bolts, with only the edge close to the bottom of the modern wall 1. The entire load of the lifting column 5, positioning column 4, and supporting diagonal rod 9 is transferred to the ground. There are no expansion bolts or welding points that penetrate or adhere to the wall, completely eliminating the hidden dangers of through holes, water seepage, and weathering in the wall.

[0065] No risk of damage during construction: All adjustment and locking operations are concentrated in the adjustment holes 6, positioning holes 401, and lifting holes 801 of the support structure itself, eliminating the need for cutting, chiseling, or welding on the wall surface; the wall support surface 11 only flexibly adheres to the weak areas of the wall surface, eliminating the need for impact or mechanical removal of the original surface layer, and the original plaster layer and brickwork are not damaged by construction bumps.

[0066] No damage left after demolition: After the support period is completed, the demolition process only involves dismantling the bolts of the support structure itself and the contoured column 13. There is no need to repair or fill the holes in the wall. The original wall finish and masonry texture are completely preserved, and there are no mottled and messy repair scars after the demolition of traditional support.

[0067] IV. Defect 4: Traditional structural support is bulky, and external wall components encroach on building setbacks, street-front green spaces, and public spaces, altering the original planning and landscape of the neighborhood. Compared to the shortcomings of existing technologies, traditional methods of reinforcing shear walls and external steel frame supports occupy street-side space, compress street width, and disrupt the original street and neighborhood spatial planning texture of workers' new villages and Minhang Street, this patent innovatively proposes a small-footprint support structure design. The entire set of support units is arranged close to the bottom of the wall, occupying very little space.

[0068] Miniaturized integrated support structure: The entire support unit is based on the support base plate 2 that is close to the bottom of the wall. The lifting columns 5 and positioning columns 4 are vertically concentrated in a very small area on the side of the wall. There are no large diagonal frames or thickened shear walls extending outward, and it does not occupy the original building setback, street green space, or public activity space of the building.

[0069] Space adapted to the original street scale: The small-footprint support structure is housed inside the three-enclosure imitation column surface 13. The overall appearance is only an imitation column shape that fits the wall, which will not compress the street width or change the original width-to-height ratio of the street, and retain the original planning characteristics of the open street and corner square of Minhang Street; When multiple sets of supports are arranged side by side, each set of units is arranged compactly along the wall, without destroying the low-density and transparent neighborhood balance of the Workers' New Village.

[0070] Flexible switching of working conditions reduces space occupation: In the case of independent roof support, the entire structure can be laid out separately from the wall and independently landed with the support of the four sides of the enclosure, without occupying the space around the building's exterior wall, and is suitable for repair projects with different site space restrictions.

[0071] V. Defect 5: The conventional support height adjustment has low flexibility, poor adaptability to layered support and simultaneous reinforcement of multiple weak points, and it is impossible to adjust the support height simultaneously at multiple points and in layers. Compared with the shortcomings of existing technologies, traditional support lifting and adjustment has few gears and single-point fixation, making it difficult to match multiple cracked, hollow, and weak areas of the wall at different heights in layers, and lacking flexibility in multi-point synchronous reinforcement; this patent innovatively adopts a dual-column coordinated lifting and locking mechanism of lifting column 5 + positioning column 4, combined with multiple sets of upper and lower arranged support diagonal rods 9 to achieve multi-point layered independent height adjustment.

[0072] Double column synchronous limit adjustment: The vertical moving fixed block 7 is inserted into the vertical groove of the lifting column 5 to achieve overall lifting. The positioning block 8 is sleeved on the positioning column 4 through the lifting hole 801 and follows the lifting synchronously. The two sets of components are linked synchronously to ensure that the wall support surface 11 is always vertically attached to the wall during the lifting process. The lifting stroke is smooth and can accurately match the wall defect points at any height.

[0073] Multi-layer independent locking structure: The lifting column 5 is vertically arranged with multiple sets of adjustment holes 6, the positioning column 4 is arranged with multiple sets of positioning holes 401, and after a single set of support diagonal rods 9 is adjusted to the target height, it is independently locked by fixing bolts 10 and positioning bolts 802; the multiple sets of support diagonal rods 9 arranged vertically can be locked at different heights respectively. Construction step I realizes the layered independent support of the upper, middle and lower weak areas of the wall, which is suitable for the current situation of scattered wall defects and different heights.

[0074] Multi-unit linkage expansion: The complete seamless modern wall support system can be deployed with multiple joint support units. Each unit can independently adjust its height and support strength, and can simultaneously reinforce long continuous modern walls in sections and layers. It is suitable for large-scale renovation projects of contiguous street buildings and large-scale workers' new villages.

[0075] 6. Defect 6: Traditional support functions are limited, only capable of lateral wall reinforcement, unable to simultaneously support the vertical load-bearing capacity of the building roof, and lacking an integrated wall-roof protection solution. Compared to the shortcomings of existing technologies, commercially available support systems only have the function of reinforcing one side of the wall and do not have an integrated wall-top support structure. Repair projects require the separate construction of a top support, and the superposition of two sets of devices further occupies space and damages the appearance. This patent innovatively and non-obviously extends the wall support surface 11 into an integrated top support surface 12, realizing the dual functions of lateral wall reinforcement and vertical bearing of the building top.

[0076] Integrated composite support end: The wall support surface 11 and the top support surface 12 are connected in one piece. When the support diagonal rod 9 rises to the uppermost stroke of the lifting column 5, the top support surface 12 is raised to the bottom of the building. One set of structures simultaneously completes the lateral compression reinforcement of the wall and the vertical load-bearing support of the top surface, without the need for additional independent top support components.

[0077] Integrated adjustment and locking process: Under the condition of double protection of the wall and top, the basic installation and height calibration follow the original AI general construction steps. Only the support diagonal rod 9 is adjusted to the top, and the top support surface 12 is finely adjusted to fit the top pressure point before all bolts are locked. One locking mechanism simultaneously fixes the double support positions of the wall and top, simplifying the construction process and reducing the space occupation and appearance damage caused by stacking multiple sets of support components.

[0078] Multiple working conditions can be switched freely: The system has three independent working modes: ① Wall support only (three-sided enclosure contoured column surface 13); ② Integrated wall and top support (three-sided groove adapted to top surface support); ③ Top surface support alone (four-sided groove + four-sided enclosure contoured column surface, arranged separately from the wall). One set of equipment covers all support needs of the renovation project, avoiding the problem of multiple types of support devices being superimposed and exposed, which damages the streetscape.

[0079] 7. Defect 7: The renewal of modern living heritage lacks invisible support technology that is compatible with the needs of both protection and people's livelihood renovation. The needs of protection and residents' renovation are in a binary opposition, and there is no alternative minimally invasive support solution. Compared to the shortcomings of existing technologies, traditional support only considers structural safety, resulting in exposed components and wall damage. It cannot meet the needs of residents' daily use and independent renovation, and can only restrict residents' renovation in a one-size-fits-all manner, highlighting the conflict between protection and people's livelihood. This patent innovatively adopts a dual design of visually seamless masking and ground anchoring non-destructive support, which ensures the structural safety of the wall without damaging the appearance of the building facade or the wall itself, and is compatible with the dual needs of residents' daily use and heritage protection.

[0080] Seamless appearance that does not affect residents' living style: The three-layer enclosure replicates the original visual effect of the wall with the shape of the column. After the support is completed, there is no protruding steel frame on the exterior facade. It will not damage the original appearance of the building facade and residents do not need to replace the exterior wall decoration to cover the support components. It avoids modern paint covering the original facade color.

[0081] No wall damage allows residents to make reasonable modifications: the entire support does not require drilling or damage to the wall, and will not create through holes that exacerbate water seepage and weathering, reducing the need for residents to install security windows, awnings, or air conditioner brackets due to wall damage; at the same time, the support is a temporary and removable structure that can be completely removed after the support period ends, and will not permanently occupy residents' outdoor activity space.

[0082] Modular and detachable for long-term use: All components are bolted together and detachable. Multiple units can be flexibly added or removed according to residents' renovation and repair needs. They do not need to be permanently fixed to the building perimeter. Under the premise of ensuring the safety of the wall structure, they do not restrict the reasonable renovation of residents' courtyards and indoor spaces, thus solving the dual conflict between people's livelihood renovation and wall appearance protection.

[0083] 8. Defect 8: Modern heritage renovation lacks specific support construction standards; general civil engineering techniques damage fragile walls; and a complete set of non-destructive support construction systems are lacking. Compared to the shortcomings of existing technologies, which only apply the standard of civil engineering support for ordinary commercial housing in the renovation of old buildings, there is no complete set of minimally invasive support construction process adapted to thin-walled brick-concrete walls, and the construction lacks standardized and non-destructive control steps; this patent innovatively and non-obviously provides a complete standardized and seamless modern wall support construction method, forming a non-destructive special process system for the entire process of surveying, installation, adjustment, wall top support, and demolition.

[0084] Pre-construction survey and precise control: Construction step A: Pre-construction survey of wall defects and support layout areas, targeted planning of single / multiple support layouts, avoiding blind construction and large-area contact with the wall, reducing stress damage to the wall from the source; Standardized non-destructive installation process: Step BD: Ground cleaning, base plate anchoring, and column alignment without contact with the wall throughout the process; Step EI: Layered lifting, flexible fitting, and independent locking, avoiding violent squeezing and wall chiseling throughout the process; Standardized operating procedures for different working conditions: Three standardized operating procedures are distinguished for pure wall support, integrated wall and top support, and separate top support, with corresponding fencing switching and stress inspection procedures (checking that the rubber support surface is evenly attached and the top surface is evenly stressed). Standardized non-destructive demolition procedures: The steps follow the reverse demolition logic of "first remove the covering fence → loosen the bolts and lower the support surface → dismantle the columns → remove the base plate". The support surface is completely separated from the wall and top surface before the main structure is dismantled. This prevents the wall from being bumped or pulled during the demolition process, forming a complete set of support construction technology system adapted to modern thin-walled brick and concrete walls, filling the gap in specialized processes in the industry.

[0085] It should be noted that the wall dimensions have been deliberately reduced in the attached drawings to clearly illustrate the supporting structure. In actual use, it is preferred to place this patent at both ends of the wall, and its dimensions include a series to adapt to different scenarios.

[0086] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.
