Description

Technical Field

[0001] This invention relates to the field of building construction engineering, and specifically to an interlaced cable-membrane structure and its installation method. Background Technology

[0002] In recent years, carbon fiber cables have gained increasing understanding and recognition for their excellent properties, such as fatigue resistance and long service life, as research and engineering practices have progressed. Currently, carbon fiber cable-membrane structures are mostly used in bridges and large-span domes, with few applications in facade carbon fiber cable-membrane structures. Existing technology for the design of carbon fiber facade cable-membrane structures mainly faces the problem of a large windward face. Facade membrane structures are often subjected to greater stress than planar membrane structures. If conventional membrane structure designs are still used, the durability of the structure will be reduced, and excessive stress on the cable-membrane can lead to safety hazards. Summary of the Invention

This invention addresses the problem that the existing technology for carbon fiber facade cable-membrane structure design mainly suffers from a large windward side. The stress on facade membrane structures is often greater than that on planar membrane structures. If a general membrane structure design is still used, the durability of the structure will be reduced, and excessive stress on the cable-membrane will cause safety hazards.

[0007] A lower arc beam is provided corresponding to the upper arc beam;

[0008] Connection units are installed on the upper and lower arc beams to connect the main structure of the building.

[0009] Several bottom membrane keel units are supported between the upper arc beam and the lower arc beam;

[0010] A plurality of outer membrane keel units are supported between the upper arc beam and the lower arc beam. The outer membrane keel units protrude outward from the plane where the upper arc beam and the lower arc beam are located. The outer membrane keel units are spaced apart on the bottom membrane keel unit.

[0011] A plurality of cable units connect the upper arc beam and the lower arc beam, the cable units being connected to the bottom membrane keel unit;

[0012] The outer membrane mounted on the outer membrane keel unit; and

[0013] The bottom membrane is installed on the bottom membrane keel unit, and the bottom membrane and the outer membrane are staggered.

[0014] A further improvement of the interlaced cable-membrane structure of the present invention is that the bottom membrane keel unit includes two bottom membrane keels, and the outer membrane keel unit includes two outer membrane keels.

[0015] A further improvement of the interlaced cable-membrane structure of the present invention is that the two bottom membrane keels in the same bottom membrane keel unit are concave or convex to each other in the plane where the upper arc beam and the lower arc beam are located, and the two outer membrane keels in the same outer membrane keel unit are concave or convex to each other corresponding to the bottom membrane keels on which they are erected.

[0016] A further improvement of the interlaced cable-membrane structure of the present invention is that the bottom membrane and the outer membrane are configured to correspond to the shapes of the bottom membrane keel and the outer membrane keel.

[0017] A further improvement of the interlaced cable-membrane structure of the present invention is that the connecting unit includes:

[0018] A first flange fixedly mounted on the upper arc beam and a second flange fixedly mounted on the lower arc beam are detachably connected to the main building structure.

[0019] A further improvement of the interlaced cable-membrane structure of the present invention is that a flange gasket is provided between the first flange and the main building structure.

[0020] A further improvement of the interlaced cable-membrane structure of the present invention is that the connecting unit further includes:

[0021] The bearing housing is fixed to the upper arc beam, and the bearing housing is detachably connected to the main building structure.

[0022] A further improvement of the interlaced cable-membrane structure of the present invention is that the interlaced cable-membrane structure further includes connecting rods that connect the bottom membrane keel in series.

[0023] A further improvement of the interlaced cable-membrane structure of the present invention is that the cable unit comprises:

[0024] Two first cable clamps are respectively connected to the upper arc beam and the lower arc beam, and the first cable clamps can also be used to tension the cables connected thereto;

[0025] The cable connected to the upper and lower arc beams via the first cable clamp; and

[0026] The cable is fixed to the second cable clamp of the bottom membrane keel along the direction of the bottom membrane keel.

[0027] The present invention also provides an installation method for an interlaced cable-membrane structure, comprising the following steps:

[0028] S1. The bottom membrane keel unit is supported and installed between the upper arc beam and the lower arc beam;

[0029] S2. The outer membrane keel unit is installed between the upper arc beam and the lower arc beam, and each outer membrane keel unit is mounted on the bottom membrane keel unit with an interval of one bottom membrane keel unit;

[0030] S3. Install the connecting unit at the corresponding positions of the upper arc beam and the lower arc beam, and hoist the installed part to the corresponding position of the main building structure and connect it to the main building structure;

[0031] S4. Fix the cable unit to the upper arc beam and the lower arc beam;

[0032] S5. Install the bottom membrane and the outer membrane onto the bottom membrane keel unit and the outer membrane keel unit respectively.

[0033] The beneficial effects of this invention are: by fixing the bottom membrane keel and the outer membrane keel to the upper and lower arc beams, and by having the outer membrane keel protrude outward from the plane of the upper and lower arc beams to form an interlaced cable membrane arrangement structure, the external force on the cable membrane is effectively distributed to the bottom membrane keel and the outer membrane keel, avoiding the concentration of force. Moreover, the spaced outer membrane keel is lighter than the overall structure of adding an outer membrane keel. Therefore, this structure balances the relationship between the strength and weight of the reinforced structure. Attached Figure Description

Detailed Implementation

[0042] This invention provides an interlaced cable-membrane structure. The purpose of this invention is to address the problem in existing carbon fiber facade cable-membrane structure designs: the large windward front of the structure. Facade membrane structures often experience greater stress than planar membrane structures. If conventional membrane structure designs are still used, the structure's durability will be reduced, and excessive stress on the cable-membrane can lead to safety hazards. The interlaced cable-membrane structure of this invention fixes the bottom and outer membrane keels to the upper and lower arc beams. The outer membrane keels are closely attached to the bottom membrane keels and protrude outwards from the plane of the upper and lower arc beams, forming an interlaced cable-membrane arrangement. This effectively distributes the external forces on the cable-membrane to the bottom and outer membrane keels, avoiding force concentration. Furthermore, the spaced-out outer membrane keels are lighter than a structure with an overall outer membrane keel, thus balancing the strength and weight of the reinforced structure.

[0043] The interlaced cable-membrane structure of the present invention will be described below with reference to the accompanying drawings.

Figure 4 This image shows a perspective view of the connecting units in the interlaced cable-membrane structure of the present invention. (See also...) Figure 5 This image shows a three-dimensional view of the keel arrangement of the interlaced cable-membrane structure of the present invention. (See also...) Figure 6 This diagram shows the installation position of the interlaced cable-membrane structure of the present invention. (See also...) Figure 7 The image shows an enlarged view of the installation position of the interlaced cable-membrane structure of the present invention.

[0045] The interlaced cable-membrane structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] like Figure 1 As shown, the present invention provides an interlaced cable-membrane structure, including: an upper arc beam 21, a lower arc beam 22, a connecting unit 31, a bottom membrane keel unit, an outer membrane keel unit, a cable unit 51, a bottom membrane 611, and an outer membrane 612.

[0047] The upper arc beam 21 and the lower arc beam 22 are correspondingly arranged and connected to the main building structure. They serve as a frame for other components, supporting the bottom membrane keel unit and the outer membrane keel unit, as well as the cable unit 51, the bottom membrane 611, and the outer membrane 612. The connecting unit 31 is arranged on the upper arc beam 21 and the lower arc beam 22, connecting the upper arc beam 21 and the lower arc beam 22 to the main building structure. The bottom membrane keel unit is supported between the upper arc beam 21 and the lower arc beam 22, and the outer membrane keel unit is also supported between the upper arc beam 21 and the lower arc beam 22. The outer membrane keel unit protrudes outward from the plane where the upper arc beam 21 and the lower arc beam 22 are located. The outer membrane keel unit is spaced apart on the bottom membrane keel unit. The bottom membrane keel unit includes two bottom membrane keels 41, and the outer membrane keel unit includes two outer membrane keels 42.

[0048] Specifically, the bottom membrane keel 41 and the outer membrane keel 42 are supported between the upper arc beam 21 and the lower arc beam 22. The outer membrane keel 42 is set tightly against the bottom membrane keel 41. Every two outer membrane keels 42 are placed on two bottom membrane keels 41 apart, meaning that only two of the four adjacent bottom membrane keels 41 have the outer membrane keel 42 supported on them. The outer membrane keel 42 protrudes outward from the plane containing the upper arc beam 21 and the lower arc beam 22, forming an arc. Compared to a structure that is perpendicular to the bottom membrane keel 41 and extends outward, the gentle transition of the arc structure is more conducive to the support between the outer membrane keel 42 and the upper arc beam 21 and the lower arc beam 22. The cable unit 51 is the same. The cable unit 51 is also connected between the upper arc beam 21 and the lower arc beam 22. However, when the cable unit 51 is in tension, a prestress can be applied to improve the load-bearing capacity of the structure. The cable membrane 61 includes a bottom membrane 611 and an outer membrane 612, which are installed on the bottom membrane keel unit and the outer membrane keel unit respectively. The outer membrane 612 is installed on the outer membrane keel unit, and the bottom membrane 611 is installed on the bottom membrane keel unit at intervals between the outer membrane keel units. The staggered bottom membrane keel 41 and outer membrane keel 42 disperse the concentrated force of the cable membrane 61, reduce its windward area, reduce its wind resistance, improve the load-bearing capacity of the staggered cable membrane structure, and increase the air intake of the building, thereby improving the ventilation of the building.

[0049] Furthermore, the two bottom membrane keels 41 in the same bottom membrane keel unit are concave or convex to each other in the plane where the upper arc beam 21 and the lower arc beam 22 are located, and the two outer membrane keels 42 in the same outer membrane keel unit are concave or convex to each other corresponding to the bottom membrane keels 41 on which they are erected, forming an interlaced concave and convex structure in the plane. In addition, the outer membrane keel unit protrudes out of the plane where the upper arc beam 21 and the lower arc beam 22 are located, forming a three-dimensional interlaced structure, which can effectively reduce stress concentration and improve the load-bearing capacity of the structure.

[0050] Specifically, such as Figure 3As shown, the bottom membrane 611 and the outer membrane 612 are designed with concave and convex shapes corresponding to the bottom membrane keel 41 and the outer membrane keel 42, which also enhances the load-bearing capacity of the bottom membrane 611 and the outer membrane 612 for wind resistance.

[0051] like Figure 5 The figure shows a three-dimensional view of the keel arrangement of the staggered cable membrane structure of the present invention. This arrangement method smoothly transitions from a larger facade span to a smaller facade span, which helps to reduce stress concentration in the structure.

[0052] In one specific embodiment of the present invention, the staggered cable structure further includes connecting rods 43 that connect the bottom membrane keel 41 in series. The connecting rods 43 are arranged horizontally to connect multiple bottom membrane keels 41 together, thereby reinforcing the bottom membrane keel 41. Multiple connecting rods 43 can be arranged in the vertical direction to further strengthen and fix the bottom membrane keel 41 and improve the load-bearing capacity of the bottom membrane keel 41.

[0053] In one specific embodiment of the present invention, a fixing rod 44 is provided between the bottom membrane keel 41 and the outer membrane keel 42, and the outer membrane keel 42 is mounted on the bottom membrane keel 41 to fix the bottom membrane keel 41 and the outer membrane keel 42, limit the force displacement of the outer membrane keel 42, and further strengthen the outer membrane keel 42.

[0054] Furthermore, two adjacent outer membrane keels 42 are also connected together by a fixing rod 44, and an outer membrane 612 is fixed to the two connected outer membrane keels 42.

[0055] In a preferred embodiment, the bottom membrane keel 41 and the outer membrane keel 42 are cross-connected with the web rods.

[0056] Combination Figure 1 and Figure 4 As shown, the connecting unit 31 includes: a first flange 311, a second flange, and a flange gasket 313. Connectors are pre-embedded at the installation positions of the upper arc beam 21 and the lower arc beam 22 of the main building structure for docking and installation with the first flange 311 and the second flange. The first flange 311 is fixedly set on the upper arc beam 21, and the second flange is fixedly set on the lower arc beam 22. The first flange 311 and the second flange are detachably connected to the connectors, thereby fixing the upper arc beam 21 and the lower arc beam 22 to the main building structure through the first flange 311 and the second flange, realizing the overall fixation of the staggered cable membrane structure and the main building structure.

[0057] In one specific embodiment of the present invention, a flange gasket 313 is provided between the first flange 311 and the second flange and the connecting member, respectively, to reduce the vibration between the first flange 311 and the second flange and the connecting member, strengthen the fixation, and improve the durability of the overall interlaced cable membrane structure and the main building structure.

[0058] In another preferred embodiment, the connecting unit 31 also includes a bearing seat, and a tie rod 314 is pre-embedded in the main building structure. The bearing seat is positioned on the upper arc beam 21 corresponding to the tie rod 314. The bearing seat and the tie rod 314 are detachably connected, which shares the pressure of fixing the first flange 311 and the second flange, and strengthens the fixing stability of the staggered cable membrane structure and the main building structure.

[0059] Preferably, the connector is a bearing housing, and the pull rod 314 is fixed to the bearing housing by a pin, thus achieving a firm fixation between the pull rod 314 and the connector.

[0060] like Figure 1 As shown, preferably, the cable unit 51 includes: a cable 511, a first cable clamp 512, and a second cable clamp 513.

[0061] Specifically, the two first cable clamps 512 are respectively connected to the upper arc beam 21 and the lower arc beam 22, and the first cable clamps 512 can also be used to tension the cable 511 connected thereto.

[0062] The cable 511 is connected to the upper arc beam 21 and the lower arc beam 22 via the first cable clamp 512, and is used to stabilize the upper arc beam 21 and the lower arc beam 22.

[0063] In a preferred embodiment, the second cable clamp 513 is fixed to the bottom membrane keel 41, and preferably, the second cable clamp 513 is fixed at the junction of the bottom membrane keel 41 and the connecting rod 43. Setting the second cable clamp 513 at the junction of the bottom membrane keel 41 and the connecting rod 43 helps to improve the stability of the connection between the cable 511 and the bottom membrane keel 41 and improve the structural strength.

[0064] In another preferred embodiment, the upper arc beam 21 and the lower arc beam 22 are made of steel beams, the cable unit 51 is made of carbon fiber material, and the cable membrane 61 is made of PTFE membrane.

[0065] like Figure 6 The diagram shows the installation position of the interlaced cable-membrane structure of the present invention. Figure 7 The diagram shows an enlarged view of the installation position of the interlaced cable-membrane structure of the present invention. (In conjunction with...) Figure 6 and Figure 7 As shown, this structure is suspended from the exterior of the building, so its advantages of light weight, low wind resistance, and stress concentration and dispersion are all beneficial to this installation position.

[0066] In view of the interlaced cable-membrane structure of the present invention, the present invention also provides an installation method for the interlaced cable-membrane structure, comprising the following six steps:

[0067] Step 1: Detailed design. Based on the on-site re-measurement data of the main building structure, complete the detailed design of the upper arc beam 21, lower arc beam 22, connecting unit 31, bottom membrane keel 41, outer membrane keel 42, cable unit 51, and cable membrane 61.

[0068] Step Two: Factory Prefabrication. Based on the design drawings, each component is manufactured and processed in the factory. Only after processing is completed can it be transported to the construction site for the next step of construction.

[0069] Step 3: Installation of the upper arc beam 21, lower arc beam 22, connecting unit 31, bottom membrane keel 41, and outer membrane keel 42. First, according to the design drawings, assemble the upper arc beam 21, lower arc beam 22, and bottom membrane keel 41 on the ground in sequence. After assembly, install the connecting rod 43, connecting rod 234, and outer membrane keel 42 in sequence. At the same time, install the tie rod 314 and connectors on the main building structure. Welding is used to connect each component during installation. After the above structure is assembled on the ground and the tie rod 314 and connectors are welded, transport the assembled part on the ground to the work surface by vertical transportation machinery. Fix the ground part to the main building structure by connecting the tie rod 314 and connectors to the bearing seat, the first flange 311, and the second flange, respectively. When fixing, the tie rod 314 and the bearing seat are connected by a pin, and the first flange 311 and the second flange are connected to the connectors by bolts, with a flange gasket 313 placed in the middle.

[0070] Step 4: Installation of cable unit 51. When installing carbon fiber cable unit 51, first complete the connection of carbon fiber cable 511 and carbon fiber cable anchoring clamp in the processing yard. After processing, transport it to the site. Use vertical transportation machinery to transport carbon fiber cable 511 to the work surface. After the first carbon fiber cable anchoring clamp 512 is installed, install the second carbon fiber cable clamp 513.

[0071] Step 5: Install PTFE membrane 61. When installing PTFE membrane 61, first install the PTFE bottom membrane 611 and then install the PTFE outer membrane 612. The PTFE bottom membrane 611 and PTFE outer membrane 612 should be installed on the corresponding bottom membrane keel 41 and outer membrane keel 42.

[0072] Step Six: Tensioning of carbon fiber cable 511. After the PTFE bottom membrane 611 and PTFE outer membrane 612 are installed and tensioned, the carbon fiber cable 511 can be tensioned. Once the carbon fiber cable 511 is tensioned, the relevant installation is completed.

[0073] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
