Description

Technical Field

[0001] This utility model relates to the field of structural repair and reinforcement of antique buildings, specifically to a steel cable truss reinforcement support structure for antique buildings. Background Technology

[0002] With the prosperity of the national economy, the tourism industry has also developed rapidly. Antique-style buildings, which can recreate ancient architecture and historical features, are favored by scenic spots across the country. However, ensuring the reliable load-bearing capacity and deformation resistance of the antique-style wooden structure is a primary consideration during actual construction and subsequent use.

[0003] Because antique-style buildings are primarily constructed of wood, their core is a timber frame system built from wooden components such as columns, beams, purlins, etc. This system not only bears the weight of the building but also presents an aesthetically pleasing appearance. The roof is covered with a wooden base layer composed of rafters, sheathing boards, and other components. This design not only bears the weight of the roof but also plays an important role in rain protection and thermal insulation. However, antique-style wooden buildings also face challenges such as susceptibility to decay, insect infestation, and fire. Especially after a certain number of years of use, in order to ensure their continued use and safety, appropriate reinforcement and maintenance are necessary. However, existing technologies, in practice, generally encounter the following problems:

[0004] 1. Damaging the original appearance and structural integrity of the antique replica:

[0005] Adding columns or walls is the most direct but also the most destructive method. New columns or walls will cut into the original open space, block the view, and destroy the spatial pattern and historical atmosphere of the ancient building. Moreover, their foundation construction may disturb the original foundation of the ancient building.

[0006] 2. While large steel frames can provide support, their components are typically bulky and heavy, creating a jarring visual effect that clashes with the lightness and wooden features of antique-style buildings, severely damaging their aesthetic value. Furthermore, the frame joints may require extensive anchoring, causing significant damage to the original structure.

[0007] 3. Limited space utilization:

[0008] Whether adding columns or using large frames, it will inevitably occupy valuable interior space, limit the flexibility of functional layout, and fail to truly realize the modern demand for "column-free large spaces".

[0009] 4. Complex construction process, causing significant disturbance to the antique-style buildings:

[0010] Traditional reinforcement or addition of supporting structures often requires extensive on-site welding and concrete pouring, generating noise, vibration, and dust, posing potential threats to fragile antique-style building components and the environment. The hoisting and installation of large components also require significant space, making implementation difficult in the limited space of antique-style courtyard buildings.

[0011] 5. The structure is unreasonable and the weight is too large:

[0012] Conventional steel beams or trusses, designed to meet the demands of large spans, have large cross-sectional heights and require a significant amount of steel, resulting in a substantial increase in structural weight. This not only increases the burden on the existing foundations of the antique-style building (which may have limited load-bearing capacity) but also raises the difficulty of transportation and installation.

[0013] In view of this, the inventor of this utility model conducted in-depth research on the aforementioned defects in the prior art, which led to the creation of this case. Utility Model Content

[0014] To address the aforementioned technical challenges, we propose a steel cable truss reinforced support structure for antique-style buildings. Specifically addressing the need for column-free spaces in antique-style building renovations, we propose a technical solution combining a steel cable truss structure with steel columns and purlins to achieve both the requirement for column-free spaces and sufficient support strength.

[0015] To achieve the above objectives, the technical solution of this utility model is as follows:

[0016] An antique-style building steel cable truss reinforced support structure includes two gable wall support members, at least one partition wall support member, and several horizontal connecting purlins, all made of steel. The two gable wall support members are respectively erected on the inner sides of the two gable walls of the antique-style building. The partition wall support member is erected in the middle of the antique-style building, and the distance between the gable wall support member and the adjacent partition wall support member, as well as the distance between two adjacent partition wall support members, are the same. The horizontal connecting purlins are horizontally arranged between the gable wall support member and the adjacent partition wall support member, as well as between two adjacent partition wall support members.

[0017] The gable support component includes an upper chord, steel columns, and node connectors. The two upper chords are connected by node connectors to form an angled steel truss. The angled steel truss is erected between the gable and the roof of the antique-style building. The steel columns are erected below the front and rear ends of the angled steel truss, and the bottom ends of the steel columns are fixed in the underground concrete foundation.

[0018] The partition wall support components all include upper chords, lower chords, steel columns, and node connectors. The two upper chords and the upper and lower chords are connected by node connectors to form a triangular steel truss. The triangular steel truss is erected under the roof of the antique-style building. The steel columns are erected under the front and rear ends of the triangular steel truss, and the bottom of the steel columns is fixed in the underground concrete foundation.

[0019] Preferably, the triangular steel truss is further provided with two web members. The lower ends of the two web members are connected to the middle position of the lower chord through node connectors, and the upper ends of the two web members are respectively connected to the middle position of the two upper chords through node connectors.

[0020] Preferably, several reinforced concrete structural columns are vertically connected to the upper side of the upper chord, and tie bars are connected between adjacent reinforced concrete structural columns.

[0021] Preferably, the bottom ends of the angular steel truss and the triangular steel truss are respectively connected to steel cantilever arms in the forward and backward directions.

[0022] Preferably, a gable wall is erected above both the angular steel truss and the triangular steel truss, and the reinforced concrete structural column and tie bar are embedded inside the gable wall. The front and rear ends of the gable wall extend above the steel cantilever at the front and rear ends of the angular steel truss and the triangular steel truss, respectively.

[0023] Preferably, the bottom of the steel column is fixedly connected with anchor bolts, and steel plate pre-embedded parts are embedded in the underground concrete foundation, and the anchor bolts and steel plate pre-embedded parts are fixed together by expansion bolts.

[0024] Preferably, a rubber gasket is provided at the contact point between the steel plate embedded part and the antique building.

[0025] Preferably, the gable wall is provided with a wall cap, and the front and rear ends of the wall cap are both upturned.

[0026] Preferably, a step edge stone is also provided on the front side of the connection between the steel column and the underground concrete foundation.

[0027] Preferably, the top of the triangular steel truss is also connected to a steel cable at the middle of the lower chord.

[0028] Through the above technical solution, this utility model is designed with two gable wall support members, both made of steel, at least one partition wall support member, and several horizontal connecting purlins. The two gable wall support members are respectively erected on the inner sides of the gable walls on both sides of the antique-style building, and the partition wall support member is erected in the middle of the antique-style building. The distance between the gable wall support member and the adjacent partition wall support member, as well as the distance between two adjacent partition wall support members, are the same. The horizontal connecting purlins are horizontally arranged between the gable wall support member and the adjacent partition wall support member, as well as between two adjacent partition wall support members. Under the premise of maximizing the protection of the historical appearance and structural safety of the antique-style building, the high tensile strength of steel and the efficient bending resistance of the truss are fully utilized. Its cable members are slender, and the truss can be designed to be much lighter than traditional trusses. The prestressed steel cables actively participate in the stress, optimize the distribution of internal forces in the structure, give full play to the material properties, and save steel compared to traditional solid-web beams or ordinary trusses, resulting in a significant reduction in self-weight. Completely liberating the interior space, with no supporting columns, it provides maximum freedom for functional layout, perfectly meeting modern usage needs. It efficiently and lightly creates column-free, large-span spaces that fulfill the required functions. It is particularly suitable for implementation in space-constrained, high-preservation environments resembling antique buildings. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0041] Example

[0042] like Figure 1-7 As shown, an antique-style building steel cable truss reinforced support structure includes two gable wall support members 1, four partition wall support members 2, and several horizontal connecting purlins 3, all made of steel. The two gable wall support members 1 are respectively erected on the inner sides of the gable walls 4 on both sides of the antique-style building. The partition wall support members 2 are erected in the middle of the antique-style building, and the distance between the gable wall support member 1 and the adjacent partition wall support member 2, as well as the distance between two adjacent partition wall support members 2, are the same. The horizontal connecting purlins 3 are horizontally arranged between the gable wall support member 1 and the adjacent partition wall support member 2, as well as between two adjacent partition wall support members 2.

[0043] The gable support component 1 includes an upper chord 5, a steel column 6, and a node connector 7. The two upper chords 5 are connected by the node connector 7 to form an angled steel truss 8. The angled steel truss 8 is erected between the gable 4 and the roof of the antique building. The ends of the wooden purlins 9 at the original roof are fixed to the upper chords 5 of the angled steel truss 8. The steel column 6 is erected below the front and rear ends of the angled steel truss 8, and the bottom end of the steel column 6 is fixed in the underground concrete foundation 10.

[0044] The partition wall support component 2 includes an upper chord 5, a lower chord 11, a steel column 6, and a node connector 7. The two upper chords 5 and the upper chord 5 and the lower chord 11 are connected by the node connector 7 to form a triangular steel truss 12. The triangular steel truss 12 is erected under the roof of the antique building. The ends of the wooden purlins 9 at the original roof are fixed to the upper chords 5 of the triangular steel truss 12. The steel column 6 is erected under the front and rear ends of the triangular steel truss 12, and the bottom end of the steel column 6 is fixed in the underground concrete foundation 10.

[0045] To further enhance the support strength of the triangular steel truss 12, two web members 13 are also provided inside the triangular steel truss 12. The lower ends of the two web members 13 are connected to the middle position of the lower chord 11 through node connectors 7, and the upper ends of the two web members 13 are respectively connected to the middle position of the two upper chords 5 through node connectors 7. The top of the triangular steel truss 12 and the middle position of the lower chord 11 are also connected to a steel tie 23.

[0046] Several reinforced concrete structural columns 14 are vertically connected to the upper side of the upper chord 5, and tie bars 15 are connected between adjacent reinforced concrete structural columns 14, thereby further strengthening and fixing the angled steel truss 8 from the upper side. Steel cantilever arms 16 extend from the bottom of the angled steel truss 8 and the triangular steel truss 12 in the front and rear directions, respectively, to support the weight of the masonry gable wall 17 from both ends. Gable walls 17 are erected above both the angled steel truss 8 and the triangular steel truss 12, and the reinforced concrete structural columns 14 and tie bars 15 are embedded within the gable walls 17. The front and rear ends of the gable walls 17 extend above the steel cantilever arms 16 at the front and rear ends of the angled steel truss 8 and the triangular steel truss 12, respectively. This design allows the gable walls 17 to cover the construction top surface of the triangular steel truss 12 and the angled steel truss 8, while also providing an aesthetically pleasing appearance.

[0047] Anchor bolts 18 are fixedly connected to the bottom of the steel column 6, and steel plate embedded parts 19 are pre-embedded in the underground concrete foundation 10. The anchor bolts 18 and the steel plate embedded parts 19 are fixed together by expansion bolts. The anchor bolts 18 bear the function of "tensile resistance + shear resistance" to avoid destructive welding or chiseling of the original structure of the antique building, and minimize intervention.

[0048] The gable wall 17 is provided with a wall cap 20, the front and rear ends of which are both upturned. This further enhances the technical effect of protecting the main body and internal components of the gable wall from rain and wind.

[0049] In order to further protect the connection between the steel column 6 and the underground concrete foundation 10 from the front, and also to enhance the pavement strength of the ground in front of the connection between the steel column 6 and the underground concrete foundation 10, a step stone 21 is also provided in front of the connection between the steel column 6 and the underground concrete foundation 10.

[0050] Rubber pads 22 are placed at the contact points between the steel plate embedded part 19 and the antique building to avoid damage to the components due to rigid contact. A wall cap 20 is provided on the gable wall 17. The front and rear ends of the wall cap 20 are both upturned, which can prevent rainwater from flowing directly down and causing inconvenience to pedestrians on the road, and also enhance the aesthetics.

[0051] The following describes the specific implementation steps using a typical example of the renovation of an antique-style building (such as the renovation of a brick-and-wood structure hall in a famous scenic spot, with a span of 9.6 meters):

[0052] 1. Preliminary survey and design:

[0053] - The load-bearing capacity of the original walls of the antique-style building is tested to determine the anchorage locations at both ends of the truss, and finally the corresponding lower-level concrete column positions are selected.

[0054] -Based on the spatial span and the load, the cable truss parameters are designed as follows: the lower chord is made of galvanized channel steel with a diameter of 120*53mm, the upper chord is made of 150×195mm H-beams, the web members are made of galvanized channel steel with a diameter of 120*53mm, the vertical steel tie rods are made of 28mm, and the truss spacing is 5.4 meters, 3.9 meters, and 3.475 meters.

[0055] 2. Component prefabrication and processing:

[0056] - All steel components (top chord, web members, and node connectors) are prefabricated in the factory, cut and drilled according to design dimensions, reducing on-site work.

[0057] 3. Anchorage node construction:

[0058] - Install steel plate embedded parts at the column positions corresponding to the pre-set anchoring positions of the antique-style concrete slab, and fix them with expansion bolts. Rubber gaskets are placed at the contact points between the embedded parts and the antique-style building to avoid damage to the components due to rigid contact.

[0059] 4. Truss installation:

[0060] - Using a segmented hoisting method, the upper chord and web members are first assembled into a half-truss on the ground, and then hoisted to the predetermined height by a small crane (such as a mini crawler crane) and temporarily fixed to the anchoring node.

[0061] - Install the lower chord, adjust the verticality and position of the truss, and finally fix the lower chord to the upper chord and web members through the node connectors to complete the overall assembly.

[0062] 5. Acceptance and commissioning:

[0063] -After installation, test the truss deflection, stress state of anchoring nodes, etc., to ensure that all indicators meet the design requirements.

[0064] - Apply anti-corrosion treatment to the connection parts (such as applying anti-rust paint), and apply decorative treatment to the steel components according to the style of the ancient building (such as spraying paint with a similar color to the wood structure) to enhance visual harmony.

[0065] The above implementation method can achieve large-span spatial support, and the on-site welding and concrete work during construction are minimal, thus minimizing disturbance to ancient buildings.

[0066] This antique-style building features a steel cable truss reinforced support structure with a steel cable truss as its core load-bearing structure. The truss consists of an upper chord, lower chord, web members, vertical tie rods, and node connectors. The lower chord uses high-strength steel, utilizing its high tensile strength to bear the tension. The upper chord and web members are made of lightweight steel (such as H-beams or square steel tubes), hinged to the steel cables via node connectors to form an integrated load-bearing system. The steel columns bear both vertical loads (structural self-weight, roof loads, etc.) and horizontal loads (wind loads, seismic forces, etc.), transferring the upper loads to the foundation.

[0067] The technical approach is as follows:

[0068] - Stress design:

[0069] Vertical loads: Roof loads and structural self-weight are transferred to the foundation through the steel frame system's "beam-column" path.

[0070] Horizontal forces: Horizontal forces such as wind loads and seismic action are resisted by the joint efforts of supports and columns. By utilizing the "geometric invariance" of the cable truss, the horizontal forces are converted into axial forces (compression / tension) in the members, thus avoiding overall lateral displacement of the structure.

[0071] Node stress: At the intersection of various members, loads must be effectively transferred through bolts, welding, or other means. The strength and stiffness of the nodes must be verified during the design process.

[0072] - Anchoring method: The bottom of the steel column is connected to the concrete foundation by anchor bolts. The anchor bolts bear the "tensile and shear resistance" role, avoiding destructive welding or chiseling of the original structure of the antique building and minimizing intervention.

[0073] In summary, the steel cable truss reinforced support structure of this antique-style building specifically achieves the following objectives:

[0074] 1. Avoid adding any new columns or walls indoors. Suitable for implementation in antique-style building environments with limited space and high protection requirements.

[0075] 2. Improve renovation efficiency. Compared with existing renovation structures, it can reduce the overall weight and minimize interference with and damage to the original structure (walls, beams and columns) of the antique-style building.

[0076] 3. It provides a more visually transparent and lighter structural solution, which can shorten the construction period and reduce the risk of damage to the antique building body from construction noise, vibration and dust.

[0077] 4. It simplifies on-site construction, reduces the impact on the environment of the antique-style building, and achieves the goal of novel design, reasonable structure, and good application effect.

[0078] The above description is only a preferred embodiment of the steel cable truss reinforcement support structure for antique buildings according to this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
