Description

Technical Field

[0001] This invention relates to the field of building structure technology, and more particularly to the field of cable-membrane structure buildings, specifically to a cable-membrane bilateral connection node and construction process for a double-layer orthogonal cable-membrane structure system. Background Technology

[0002] As a typical structural form of large-span spatial structures, cable-membrane structures have advantages such as beautiful appearance, strong span capacity, and economical and reasonable material usage, making them popular among architects and engineers. Currently, my country has successfully constructed actual engineering projects using cable-membrane structures, such as sports centers and high-speed railway stations. However, with the continuous improvement and innovation of cable-membrane structure systems, traditional component connection methods often prove inadequate for adapting to new structural systems.

[0003] In cable-membrane structures, traditional bilateral connections between cables and membranes mainly include direct laying, cable loop connections, and strap connections. Direct laying and cable loop connections are typically used in unidirectional double-layer cable net systems, such as spoke-wheel structures. Currently, orthogonal double-layer cable-membrane structures are being used in practical engineering projects, but traditional connection methods are unsuitable for structures where the upper cable net is bidirectional. After the membrane material is laid, the second-direction cables of the upper cable net cannot be effectively connected to the first-direction cables. Traditional strap connections often require breaking the membrane material at the ridge, a method that often fails to ensure the continuity of the membrane structure and alters the mechanical properties of the membrane material at the nodes.

[0004] Furthermore, in terms of on-site construction control, membrane sleeve connection presents significant construction challenges. Threading excessively long cables into the membrane sleeve often requires overcoming substantial friction between the membrane material and the cables, and the construction process may significantly impact the mechanical properties of the membrane material. Direct laying presents difficulties in controlling the construction form. Due to the inelastic nature of the membrane material, it is difficult to ensure that the designed position of the stiffening membrane matches the actual construction position, potentially leading to significant construction errors. The strap connection method involves complex construction procedures. When using strap connections, sections are set at the ridge of the flexible membrane, requiring on-site heat sealing of the waterproof membrane at the break points. This makes it difficult to strictly control construction quality. After laying, the membrane sheet needs to be heat-welded at the break points on the ridge, and the high temperatures generated during heat sealing and welding can affect the original membrane material's performance.

[0005] Therefore, it is necessary to improve the existing cable-membrane structure system's bilateral connection method between cables and membranes to meet the needs of emerging cable-membrane structure systems for cable-membrane connection methods. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the main purpose of this invention is to provide a cable-membrane bilateral connection node and construction process for a double-layer orthogonal cable-membrane structure system, so as to solve the problem that when the cable and membrane are connected on both sides in the existing double-layer orthogonal cable net structure, the second direction cable will block the laying of the first direction membrane material, making it impossible to directly lay the membrane material and penetrate the membrane sleeve. At the same time, this invention can also be used in traditional double-layer cable net systems to overcome the problem that the cable needs to overcome the great friction force when it is laid in the membrane sleeve, which leads to the great construction difficulty.

[0007] The technical solution of the present invention is as follows:

[0008] A double-layer orthogonal cable-membrane structure system includes a cable-membrane bilateral connection node, comprising: a boundary cable, which is a transverse or longitudinal cable of the double-layer orthogonal cable net in the cable-membrane structure system, the boundary cable serving as the cable-membrane connection boundary; a membrane body, composed of a back membrane, a main membrane, and a supporting member, wherein the back membrane is fixedly connected to the main membrane, and the supporting member extends through the back membrane; a sleeve, which is sleeved on the boundary cable and extends downward, with one end of the downward extension connected to a detachable profile clamp assembly; and a detachable profile clamp assembly, one end of which is connected to the sleeve, and the other end of which clamps the supporting member.

[0009] In some implementations, the dorsal membrane wraps around the support member, with the other end bent outward into an inverted V shape, and the bent portion is welded and fixed to the adjacent two main membranes using a heat-sealing welding process.

[0010] In some implementations, the support member is a continuous nylon rope or rubber rod.

[0011] In some implementations, the connector is a U-shaped clamp, with one end sleeved on the boundary cable and the other end snapped onto the outside of the split profile clamp assembly and fixed by bolts.

[0012] In some implementations, the detachable profile clamp assembly includes a first clamp and a second clamp that are interlocked with each other, with one end of the first clamp and the second clamp connected to the sleeve and the other end clamping the support member.

[0013] In some implementations, the first clamp has a first notch at its top, and the second clamp has a corresponding first protrusion at its top. The second clamp is inserted into the first notch through the first protrusion and engages with the first clamp.

[0014] In some implementations, the first clamp has a second notch in the middle, and the second clamp has a corresponding second protrusion in the middle. The second clamp is inserted into the corresponding second notch through the second protrusion and engages with the first clamp.

[0015] In some implementations, bolt holes are provided between the first recess and the second recess of the first clamp, and between the first protrusion and the second protrusion of the second clamp, respectively, for connection and fixation with the sleeve by bolts.

[0016] In some implementations, the bottom of the first clamp and the second clamp are respectively formed with arc-shaped clamping portions. After the first clamp and the second clamp are engaged, the arc-shaped clamping portions cooperate to form a slot for clamping the support member, and the slot has a gap for the dorsal membrane to pass through.

[0017] In some implementations, the boundary cable is a spine cable, positioned above the dorsal membrane for connection to the support member; or

[0018] The boundary cables are valley cables, which are set diagonally below the two boundaries of the main membrane. Supporting members are embedded in the boundaries, and the valley cables are used to connect with the supporting members of the boundaries.

[0019] This invention further provides a construction process for a cable-membrane bilateral connection node, comprising: Step 1, completing the construction of a double-layer orthogonal cable net in the cable-membrane structure system; Step 2, installing U-shaped clamps at the designated positions of the ridge cables of the double-layer orthogonal cable net; Step 3, using heat sealing to connect the ridge membrane and the main membrane, with the ridge membrane self-heat sealing to form a closed cavity, and the supporting components passing through the cavity to form a membrane body; Step 4, splicing the membrane body with the separable profile clamp assembly, and fastening the supporting components into the separable profile clamp assembly; Step 5, in a stress-free state, connecting and fixing the bottom two ends to the lower boundary cable, and using lifting equipment to lift the separable profile clamp assembly to the designated position; Step 6, fixing with bolts to connect the U-shaped clamps and the separable profile clamp assembly.

[0020] The advantages of this invention compared to the prior art are as follows: This invention proposes a double-sided cable-membrane connection node for a double-layer orthogonal cable-membrane structure system. The boundary cables of this invention are connected to the supporting components on the membrane body through sleeves and separate profile clamp assemblies, which can solve the problems of not being able to directly lay the membrane material at the flexible ridge and using membrane sleeves in double-layer orthogonal cable nets; when the membrane is connected on both sides at the flexible ridge, no segmentation is required, improving the connection efficiency of the cable-membrane system; all components can be prefabricated in advance and directly assembled on site, reducing construction costs; in terms of architectural shape, it can ensure the architectural form of the folded membrane material, change the connection position of the membrane material, avoid damage to the formwork, and better meet the membrane structure installation requirements of the double-layer orthogonal cable net structure system.

[0021] This invention improves the membrane processing method, which can solve the architectural construction form of laying membrane structure in an "inverted V" shape in double-layer orthogonal cable net structure, making the building shape more beautiful. At the same time, it makes the membrane have excellent drainage performance, continuous connection form and controllable membrane slope, which can effectively avoid water accumulation after installation.

[0022] This invention offers convenient construction and installation. The membrane body is connected to the upper cable in the orthogonal cable net structure via a connecting piece and a detachable profile clamp assembly. The membrane body and the upper cable are spaced a certain distance apart, which facilitates the lower cable to pass through the gap between the membrane body and the upper cable, avoiding the lower cable from penetrating the membrane body over a long distance and damaging it. The detachable profile clamp assembly allows for direct assembly, simplifying the construction process.

[0023] This invention connects the membrane body and the boundary cables using U-shaped clamps. The membrane stress is ultimately transferred to the boundary cables in the form of a "point load." Uneven local stress distribution in the membrane body can be redistributed through a split profile clamp assembly. This connection method has a smaller impact on the cable net's shape due to uneven local stress in the membrane body, and the overall stress trend is basically consistent, simplifying the force transmission path. The membrane stress is transferred to the cable net system as a uniformly distributed concentrated load through the split profile clamp assembly and the connecting piece, preventing the cable net shape from deviating from the design shape due to uneven tension and shape of the membrane body.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0037] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] Traditional cable-membrane connections use a single-sided connection, meaning the boundary of the membrane structure is directly connected to the cable. This method is not suitable for connections in orthogonal cable nets. In traditional double-layer cable nets, there are valley cables and ridge cables. The nodes that pull the membrane up from the middle to form a V-shape are double-sided nodes. However, this V-shaped cable-membrane connection method cannot be used in orthogonal cable nets because traditional membrane construction involves laying the entire structure or threading it through a membrane sheath. If the upper cable net is orthogonal, this cannot be done, which would affect its construction and installation.

[0040] In addition, in bilateral connection structures, the boundary cables are often set at the ridge of the membrane, where the membrane is broken. Then, a new layer of membrane is laid at the break point to connect the boundary cables and the membrane together. In the orthogonal double-layer cable net structure system, the lower layer cable needs to pass through the membrane in the traditional bilateral connection node, which causes the membrane to be damaged and affects the overall structural stability. Therefore, the existing bilateral connection structure is not suitable for orthogonal double-layer cable net structure system.

[0041] Based on this, the present invention proposes a new cable-membrane bilateral connection node suitable for a double-layer orthogonal cable-membrane structure system. The connection node of the present invention solves the problem of cable-membrane bilateral connection of double-layer orthogonal cable net, and can effectively avoid the problem of the membrane breaking at the ridge and the boundary cables needing to pass through the membrane.

[0042] The implementation of the present invention will be described in detail below with reference to preferred embodiments.

[0043] like Figure 1 , Figure 2 As shown, this invention proposes a double-sided cable-membrane connection node for a double-layer orthogonal cable-membrane structure system, including a boundary cable 1, a membrane 3, a sleeve 5, and a separate profile clamp assembly 7. This invention connects the boundary cable 1 and the membrane 3 through the sleeve 5 and the separate profile clamp assembly 7, which changes the traditional connection approach, avoids long-distance penetration through the membrane 3, and solves the problem of double-sided connection in orthogonal cable nets.

[0044] As is easily understood, the bilateral connection node mentioned in this invention refers to the node in a double-layer orthogonal cable net structure where the boundary cable 1 pulls the membrane 3 up from the middle to form a V-shaped structure.

[0045] Specifically, boundary cable 1 is the upper layer cable in the orthogonal cable net of the cable-membrane structure system. It can be a cable distributed laterally or a cable distributed longitudinally. Boundary cable 1 serves as the boundary connecting the cable and membrane.

[0046] It is easy to understand that in an orthogonal cable net structure, there are orthogonally distributed upper and lower cables. The upper cables directly bear the load and transfer part of the load to the central ring in the form of support reaction forces, while the lower cables bear the concentrated load transmitted from the central ring.

[0047] The membrane 3 is composed of a dorsal membrane 301, a main membrane 302 and a support member 303. The dorsal membrane 301 is connected and fixed to the main membrane 302, and the support member 303 passes through the dorsal membrane 301.

[0048] One end of the connector 5 is fitted onto the boundary cable 1 and extends downwards, while the other end extends downwards and connects to a separate profile clamp assembly 7, which is used to clamp the support member 303. By using the connector 5 to extend downwards, the traditional connection position between the cable and the membrane is changed, making continuous laying of the double-layer orthogonal cable net membrane material possible. This avoids the problem in traditional orthogonal cable nets where, after the membrane material is laid on the upper cable net, the lower cable in the other direction is blocked and must be broken or the membrane is divided into sections. Breaking the lower cable or dividing the membrane into sections is not allowed, thus effectively solving the problem of direct membrane material laying.

[0049] The detachable profile clamp assembly 7 includes a first clamp 701 and a second clamp 702 that are interlocked with each other. One end of the first clamp 701 and the second clamp 702 are connected to the sleeve 5, and the other end clamps the support member 303.

[0050] By using a separate profile clamp assembly 7 to clamp the support member 303, the membrane material is connected. Several separate profile clamp assemblies 7 can be used flexibly according to the length of the specific cable and membrane, avoiding the problem of long-distance membrane penetration required in traditional connection methods, which is very inconvenient for construction.

[0051] It is easy to understand that with traditional connection nodes and laying methods, the membrane material is directly laid or the cable sleeve is passed through. The membrane material is in direct contact with the boundary cable, making it difficult to guarantee the position of the cable structure during construction. During construction, uneven local stress distribution or stress concentration may occur in the membrane structure. This may directly lead to a large deviation between the construction position and the design position of the cable net structure, affecting the overall structure. In this invention, the membrane body 3 and the boundary cable 1 are connected by the sleeve 5. The stress of the membrane body 3 will eventually be transferred to the boundary cable 1 in the form of "point load". Uneven local stress distribution of the membrane body 3 can be redistributed by the split profile clamp assembly 7. With this connection method, the uneven local stress of the membrane body 3 has little impact on the position of the cable net, and the overall stress trend is basically consistent.

[0052] See Figure 2 , Figure 3 The dorsal membrane 301 wraps around the support member 303. Before being stressed, the other end is in a straight line. After being pulled up by the boundary cable 1, it bends outward into an inverted V shape. The bent part is welded and fixed to the adjacent two main membranes 302 by heat sealing welding process.

[0053] The ridge membrane 301 wraps around the supporting member 303 and the wrapping opening is sealed by welding. The ridge membrane 301 is in a straight line shape and is then heat-welded to the main membrane 302. These components can be prefabricated in the factory and assembled directly on the construction site. On-site, the tension of the boundary cable 1 causes the ridge membrane 301 and the main membrane 302 to bend into an inverted V shape, forming a double-sided connection node. In the factory, the membrane material is threaded through the ridge membrane with strands, and then the ridge membrane and the main membrane are heat-welded, which facilitates on-site connection with the profile clamps and avoids long-distance membrane threading during on-site construction.

[0054] This invention improves the processing method of membrane body 3, which can be effectively applied to a double-layer orthogonal cable membrane structure system to ensure the building shape, simplify the on-site construction process, facilitate installation, and ensure that the membrane surface is flat after the nodes are assembled. Under the double-layer "V" shaped building shape, no water will accumulate, thus optimizing the building's drainage performance. If a membrane sleeve is laid or installed, it is not easy to achieve in a double-layer orthogonal cable net, and the construction difficulty is relatively large. If the local stress on the membrane surface is uneven or wrinkles are generated, it will have a certain impact on the building's drainage and easily lead to water accumulation.

[0055] In some embodiments, the membrane 3 is not limited to the material used to make it. Depending on the building requirements, different membrane materials such as E-type, P-type, and G-type can be selected for the membrane 3.

[0056] In some embodiments, the support member 303 may be selected from supports of different materials such as a full-length nylon rope or a rubber rod.

[0057] In some embodiments, multiple engagement positions can be provided to enhance the clamp's engagement capability, depending on the required clamping force. Preferably, the invention designs two engagement positions to prevent radial expansion deformation of the clamp's cross-section due to force distribution, thus achieving a good clamping effect.

[0058] See Figures 4 to 6 The first clamp 701 has a first notch 7011 at its top, and the second clamp 702 has a corresponding first protrusion 7021 at its top. The second clamp 702 is inserted into the first notch 7011 through the first protrusion 7021 and engages with the first clamp 701.

[0059] See also Figures 4 to 6 The first clamp 701 has a second recess 7012 in the middle, and the second clamp 702 has a corresponding second protrusion 7022 in the middle. The second clamp 702 is inserted into the corresponding second recess 7012 through the second protrusion 7022 and engages with the first clamp 701.

[0060] See Figure 4 The cross-sections of the first notch 7011 and the second notch 7012 are both rectangular frames, with an upward-facing opening on the right side of each rectangular frame. (See attached image.) Figure 5 The cross-section of the first protrusion 7021 and the second protrusion 7022 is hook-shaped. The first protrusion 7021 and the second protrusion 7022 are both downward-facing protrusions, which facilitates insertion into the corresponding openings of the first recess 7011 and the second recess 7012.

[0061] See Figure 1 , Figure 6 and Figure 7 The connector 5 is a U-shaped clamp, with one end sleeved onto the boundary cable 1 and the other end snapped onto the outside of the first clamp 701 and the second clamp 702 and fixed by bolts. By sleeved onto the upper cable with the U-shaped clamp, the intersection of cables in the double-layer orthogonal cable net can be completely avoided. It is equivalent to using the U-shaped clamp to move the connection of the membrane material to the bottom, and then connecting the membrane material with a separate clamp to form a complete and continuous V-shaped double-sided structure.

[0062] See Figure 6 The first clamp 701 has a bolt hole between the first recess 7011 and the second recess 7012, and the second clamp 702 has a corresponding bolt hole between the first protrusion 7021 and the second protrusion 7022. The first clamp 701 and the second clamp 702 are fixed together by bolts.

[0063] See also Figure 1 , Figure 6 and Figure 7 The bottom end of the socket 5 has the same bolt hole as the bolt holes of the first clamp 701 and the second clamp 702. The socket 5 is connected and fixed to the first clamp 701 and the second clamp 702 through the bolt through hole corresponding to the bolt hole.

[0064] The present invention optimizes the bolt positions and engagement positions of the first clamp 701 and the second clamp 702 by cross-section optimization, and the optimized positions are fully longitudinally connected, saving materials.

[0065] See Figures 4 to 6 The bottom of the first clamp 701 and the second clamp 702 are respectively formed with arc-shaped clamping parts. After the first clamp 701 and the second clamp 702 are engaged, the arc-shaped clamping parts cooperate to form a slot for clamping and supporting member 303. A gap is left at the bottom of the slot for the dorsal membrane 301 to pass through.

[0066] Preferably, the edge of the slit is designed as a smooth arc to prevent the dorsal membrane 301 from rubbing against the edge of the slit when it passes through, thus preventing damage to the membrane 3.

[0067] The first clamp 701 and the second clamp 702 are not limited to specific materials and can be made of various materials such as aluminum and steel. The specific material and cross-sectional dimensions are selected according to the building structure and design strength requirements. Aluminum and steel are easy to cast in one piece. By designing separate profile clamps and setting up a multi-interlocking assembly form from the component perspective, the assembly can facilitate construction, prevent long-distance penetration of membrane material, and the multi-interlocking can prevent the clamps from opening and deforming.

[0068] See also Figure 1 The boundary cable 1 can be either a ridge cable 101 or a valley cable 102. When the boundary cable 1 is a ridge cable 101, the ridge cable 101 is located above the bend of the membrane body 3, that is, above the ridge membrane 301, and is used to connect with the support member 303 at the bend of the membrane body 3. When the boundary cable 1 is a valley cable 102, the valley cable 102 is located diagonally below the two boundaries of the membrane body 3, that is, diagonally below the two boundaries of the main membrane 302. The membrane boundary is embedded with the support member 303, and the valley cable 102 is used to connect with the support member 303 of the membrane boundary.

[0069] In some embodiments, the boundary cable 1 is not limited to the construction material and manufacturing method, and cable components such as steel wire bundles, steel wire ropes, steel strands, sealing cables, etc. are used according to the building structure conditions.

[0070] The construction process of the cable-membrane double-sided connection node of the present invention is as follows:

[0071] Step 1: Complete the construction of the double-layer orthogonal cable net in the cable-membrane structure system;

[0072] Step 2: Install U-shaped clamps at the designated positions of the ridge cables in the double-layer orthogonal cable net; the number and position of the U-shaped clamps are determined by the design, and temporary fixing measures are taken.

[0073] Step 3: The membrane body is prefabricated in the factory. The back membrane and the main membrane are connected by heat sealing. The back membrane needs to be heat sealed for a certain distance to form a closed cavity. Supporting components (such as nylon ropes and rubber rods) are inserted into the cavity to form the membrane body. The heat sealing length is calculated based on the target membrane surface stress.

[0074] Step four: The membrane body is spliced ​​with the separable profile clamp assembly, and the support component is fastened into the separable profile clamp assembly; specifically, the support component is placed at the first clamp, and the second clamp is fastened and assembled with the first clamp.

[0075] Step 5: With the membrane in a stress-free state, the bottom two ends are fixed to the lower boundary cable, and the detachable profile clamp assembly is lifted to the set position using lifting equipment (such as an electric hoist).

[0076] Step 6: Secure with bolts, connecting the U-shaped clamp to the detachable profile clamp assembly.

[0077] The boundary cable of the present invention is connected to the supporting members on the membrane through a sleeve and a separate profile clamp assembly. When connecting the bilateral nodes in the orthogonal cable net, it is not necessary to damage the membrane, thereby improving the connection efficiency of the cable and membrane, reducing construction costs, and better meeting the needs of the double-layer orthogonal cable net structure system.

[0078] It will be readily understood by those skilled in the art that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
