Description

Technical Field

[0001] The invention relates to the technical field of building structure design, in particular to a single-layer orthogonal large-opening cable membrane structure. Background Art

[0002] At present, the large-span saddle-shaped roof of the stadium often adopts a spoke-type cable net structure. The traditional spoke-type cable net "rainwater flows from the outer ring high area to the inner ring high area, then from the inner ring high area to the inner ring low area, and finally from the inner ring low area to the outer ring low area and enters the rain gutter". Therefore, the drainage pipes are concentrated in the outer ring low area, which has a great impact on the architectural effect and is easy to cause rainwater to gather, such as poor drainage. In addition, this drainage design cannot achieve natural drainage in areas with relatively flat roofs, and special drainage pipes need to be installed under the area. When the drainage pipes under the roof are located above the audience seats, it has a great impact on the architectural effect.

[0003] In order to enrich the roof shape or deal with the roof drainage problem more effectively, the roof can adopt a folded membrane structure arranged in one direction. At this time, if the main force-bearing structure still adopts the spoke type, it will not match the folded membrane structure geometrically, forming a more complex conversion structure, which is difficult to process and construct, affecting the architectural effect. Summary of the invention

[0004] The purpose of the present invention is to provide a single-layer orthogonal large-opening cable membrane structure with a reasonable and simple structural design. It does not need to set a drainage pipe below the roof, which not only solves the drainage problem of the roof, but also ensures a better building effect.

[0005] In order to achieve the above object, the present invention provides a single-layer orthogonal large-opening cable membrane structure, comprising an outer compression ring beam, an inner ring beam, an orthogonal cable net structure, a folded membrane structure and a membrane surface support structure; wherein,

[0006] The orthogonal cable net structure is stretched between the outer pressure ring beam and the inner ring beam, and is composed of a plurality of stabilizing cables distributed along the X-axis and a plurality of load-bearing cables distributed along the Y-axis. The load-bearing cables are arranged parallel to the X-axis, and the stabilizing cables are arranged parallel to the Y-axis. The stabilizing cables are vertically connected to the load-bearing cables.

[0007] The membrane surface support structure comprises a plurality of support members and a plurality of connecting cables distributed along the X-axis, wherein the connecting cables are located above the orthogonal cable net structure and are parallel to the stabilizing cables, one end of the connecting cables is connected to the outer pressure ring beam, and the other end is connected to the inner ring beam or the outer pressure ring beam, and the support members are arranged on the orthogonal cable net structure and are used to support the connecting cables;

[0008] The folded membrane structure comprises a plurality of folded membranes laid between adjacent stabilizing cables and connecting cables, and the folded membranes between two adjacent connecting cables form a drainage ditch parallel to the Y axis.

[0009] Optionally, the connecting rope is located directly above the stabilizing rope.

[0010] Optionally, the projection of the connecting cable on the orthogonal cable net structure does not overlap with the stabilizing cable.

[0011] Optionally, the projection of the connecting rope on the orthogonal cable net structure is located in the middle of two adjacent stabilizing ropes.

[0012] Optionally, the support member is arched or inverted V-shaped, and both ends of the support member are respectively connected to two adjacent connection nodes of the orthogonal cable net structures distributed along the X-axis, and the vertex of the support member is connected to the connecting cable.

[0013] Optionally, the supporting member is an upright pole, which is located on the load-bearing cable and has a top end connected to the connecting cable.

[0014] Optionally, the supporting member is connected to the orthogonal cable net structure and the connecting cable via a cable clamp.

[0015] Optionally, the outer pressure ring beam is circumferentially provided with an annular drainage channel connected with the drainage ditch.

[0016] Optionally, a rain gutter is provided at the lowest position of the annular drainage channel.

[0017] Optionally, the folding film is made of PVC film, PTEF film or ETFE film.

[0018] The present invention provides a single-layer orthogonal large-opening cable-membrane structure, which has at least one of the following beneficial effects:

[0019] 1) By setting the folded membrane and its supporting structure on the single-layer orthogonal cable net structure, the main force-bearing structure and the membrane structure have clear division of labor, the force is simple, and the architectural effect of the folded membrane is achieved at the same time;

[0020] 2) The single-layer orthogonal cable net has greater stiffness and anti-progressive collapse performance than the single-layer spoke cable net;

[0021] 3) By laying the folded membrane on the orthogonal cable net structure and membrane surface support structure, a drainage ditch extending along the Y-axis direction is formed, so that rainwater is directly discharged from the high area of ​​the roof to the low area of ​​the outer ring. There is no need to set up a drainage pipe below the surface within the roof range, which not only solves the drainage problem of the roof, but also ensures a better building effect.

[0030] Embodiment 1

[0031] Please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of a single-layer orthogonal large-opening cable membrane structure provided in Example 1 of the present invention. Figure 2Schematic diagram of an orthogonal cable net structure provided in Example 1 of the present invention. This embodiment provides a single-layer orthogonal large-opening cable membrane structure, including an outer pressure ring beam 1, an inner ring beam 2, an orthogonal cable net structure, a folded membrane structure and a membrane surface support structure; wherein,

[0032] The orthogonal cable net structure is stretched between the outer compression ring beam 1 and the inner ring beam 2. The orthogonal cable net structure is composed of a plurality of stabilizing cables 3 distributed along the X-axis and a plurality of load-bearing cables 4 distributed along the Y-axis. The load-bearing cables 4 are arranged parallel to the X-axis, and the stabilizing cables 3 are arranged parallel to the Y-axis. The stabilizing cables 3 are vertically connected to the load-bearing cables 4.

[0033] The membrane surface support structure comprises a plurality of support members 5 and a plurality of connecting cables 6 distributed along the X-axis, wherein the connecting cables 6 are located above the orthogonal cable net structure and are parallel to the stabilizing cables 3, one end of the connecting cables 6 is connected to the outer pressure ring beam 1, and the other end is connected to the inner ring beam 2 or the outer pressure ring beam 1, and the support members 5 are arranged on the orthogonal cable net structure and are used to support the connecting cables 6;

[0034] The folded surface membrane structure comprises a plurality of folded surface membranes laid between the adjacent stabilizing cables 3 and the connecting cables 6, and the folded surface membranes between two adjacent connecting cables 6 form a drainage ditch 7 parallel to the Y axis.

[0035] By setting the folded membrane and its supporting structure on the single-layer orthogonal cable net structure, the main force-bearing structure and the membrane structure have clear division of labor, simple force-bearing, and at the same time achieve the architectural effect of the folded membrane. In addition, the folded membrane structure naturally forms a drainage ditch 7, and rainwater is directly discharged from the high area of ​​the roof to the low area of ​​the outer ring, without the need to set a drainage pipe under the roof, and the architectural effect is guaranteed.

[0036] Specific, combined Figure 2 , the orthogonal cable net structure is stretched between the outer pressure ring beam 1 and the inner ring beam 2, and the orthogonal cable net structure is composed of a number of stabilizing cables 3 distributed along the X-axis and a number of load-bearing cables 4 distributed along the Y-axis. The X-axis and the Y-axis are two directions perpendicular to each other on the horizontal plane. The load-bearing cables 4 are arranged parallel to the X-axis, and the stabilizing cables 3 are arranged parallel to the Y-axis. The stabilizing cables 3 are vertically connected to the load-bearing cables 4. It should be understood that the orthogonal cable net structure mentioned here is stretched between the outer pressure ring beam 1 and the inner ring beam 2, which does not specifically refer to the situation where the two ends of the orthogonal cables (stabilizing cables 3 and load-bearing cables 4) are respectively connected to the outer pressure ring beam 1 and the inner ring beam 2. Considering the problem of the large central opening of the orthogonal cable net structure, when the orthogonal cables do not pass through the large central opening, the two ends of the orthogonal cables are connected to the outer pressure ring beam 1.

[0037] Please continue to refer to Figure 1A membrane surface support structure is arranged on the orthogonal cable net structure, and the membrane surface support structure includes a plurality of support members 5 and a plurality of connecting cables 6 distributed along the X-axis, the connecting cables 6 are located above the orthogonal cable net structure and are parallel to the stabilizing cables 3, one end of the connecting cables 6 is connected to the outer pressure ring beam 1, and the other end is connected to the inner ring beam 2 or the outer pressure ring beam 1, the support members 5 are arranged on the orthogonal cable net structure and are used to support the connecting cables 6.

[0038] Preferably, the support member 5 is in an arch or inverted V shape, and the two ends of the support member 5 are respectively connected to the connection nodes of two adjacent orthogonal cable net structures distributed along the X axis (the connection nodes of the stabilizing cable 3 and the load-bearing cable 4), and the vertex of the support member 5 is connected to the connecting cable 6. The support member 5 is a rigid structure, which can be formed by splicing two rigid rods or an integrally formed structure, and the present application does not limit this.

[0039] In this embodiment, the support member 5 is arched. It can be understood that the shape of the support member 5 can be adjusted according to the requirements of the architectural shape, and the curvature of the membrane surface can be changed by adjusting the curvature of the arch of the support member 5, thereby adjusting the architectural effect.

[0040] In this embodiment, the support member 5 can be connected to the orthogonal cable net structure and the connecting cable 6 through a cable clamp. The cable clamp can be individually designed according to requirements to ensure the connection stability between the support member 5 and the orthogonal cable net structure and the connecting cable 6. Since the cable clamp is a common component in the art, the present application does not limit the specific structure of the cable clamp.

[0041] As a preferred example in this embodiment, the connecting rope 6 is located directly above the stabilizing rope 3. Assuming that the connecting rope 6 is located above the first stabilizing rope, and the two stabilizing ropes 3 on the adjacent sides of the first stabilizing rope 3 are respectively recorded as the second stabilizing rope and the third stabilizing rope, the folding surface membrane is laid between the connecting rope 6 and the second stabilizing rope and the third stabilizing rope. At the same time, the two ends of the supporting member 5 are respectively connected to the second stabilizing rope and the third stabilizing rope, and the vertex is connected to the connecting rope 6. The supporting member 5 can also be used to support the folding surface membrane. At this time, the formation of the folding surface membrane between the connecting rope 6 and the second stabilizing rope and the third stabilizing rope matches the shape of the supporting member 5, and the folding surface membrane between the two adjacent connecting ropes 6 will form a drainage ditch 7 parallel to the Y axis.

[0042] As another preferred example in this embodiment, Figure 1, the projection of the connecting rope 6 on the orthogonal rope net structure does not overlap with the stabilizing rope 3, that is, the connecting rope 6 is not located directly above the stabilizing rope 3. The projection of the connecting rope 6 on the orthogonal rope net structure is located between the first stabilizing rope and the second stabilizing rope, and the folding surface membrane is laid between the connecting rope 6 and the first stabilizing rope and the second stabilizing rope, respectively. At this time, the two ends of the supporting member 5 are respectively connected to the first stabilizing rope and the second stabilizing rope, and the vertex is connected to the connecting rope 6.

[0043] The above two examples can be adjusted according to the architectural modeling requirements, and this application does not impose any restrictions on this.

[0044] Preferably, the projection of the connecting rope 6 on the orthogonal cable net structure is located in the middle of two adjacent stabilizing ropes 3, so that the architectural shape formed is more symmetrical and beautiful.

[0045] Please continue to refer to Figure 1 The folded membrane structure includes a plurality of folded membranes laid between the adjacent stabilizing cables 3 and the connecting cables 6, and the folded membranes between two adjacent connecting cables 6 form a drainage ditch 7 parallel to the Y axis. In this embodiment, the drainage ditch 7 is V-shaped or approximately V-shaped, extending along the Y axis, and a plurality of the drainage ditches 7 are distributed along the X axis. The distribution method can be equidistant or non-equidistant, which mainly depends on the distribution method of the connecting cables 6 and the stabilizing cables 3, and the present application does not limit this.

[0046] After the folded membrane between two adjacent connecting cables 6 forms a drainage ditch 7 parallel to the Y axis, rainwater is directly discharged from the high area of ​​the roof along the drainage ditch 7 to the outer ring low area, and there is no need to set a drainage pipe below the roof. This solves the drainage problem of the roof and ensures a better building effect.

[0047] In the present embodiment, the material of the folding membrane is glass fiber.The membrane material used for building membrane structure can be roughly divided into PVC membrane, PTEF membrane and ETFE membrane according to different coating materials, and the correct selection of membrane material should consider the comprehensive factors such as the scale, purpose, form, service life and budget of its building and decide.PVC membrane is all cheaper than PTFE membrane in material and processing, and has the advantages of soft material, easy construction, but poorer than PTFE membrane in performances such as strength, durable life, fire resistance.PTFE membrane is on ultra-fine glass fiber fabric, is coated with the material that polytetrafluoroethylene resin forms, and the maximum micro of PTFE membrane is exactly that durability, fire resistance and antifouling property are high.ETFE is the toughest fluoroplastic, and it has kept the good heat resistance, chemical resistance and electrical insulation performance of PTFE, and radiation resistance and mechanical properties have a great degree of improvement, and tensile strength can reach 50MPa, close to 2 times of polytetrafluoroethylene.

[0048] In this embodiment, the folding surface membrane can be fixed on the connecting rope 6 and the stabilizing rope 3 by a membrane clip, and adjacent folding surface membranes need to be spliced ​​to prevent rainwater leakage.

[0049] In this embodiment, the single-layer orthogonal large-opening cable-membrane structure is similar to a saddle shape, and the heights of the external pressure ring beam 1 are different at different locations.

[0050] Furthermore, the outer pressure ring beam 1 is provided with an annular drainage channel connected with the drainage ditch 7 along the circumferential direction. When the heights of the outer pressure ring beam 1 are not uniform, the annular drainage channel can be provided to facilitate rainwater entering the outer ring area so that rainwater in the outer ring high area can naturally flow to the outer ring low area, so as to centrally collect rainwater in the outer ring area, avoid the need to provide drainage pipes under each part of the outer pressure ring beam 1, and improve the aesthetics of the building.

[0051] Furthermore, a rain gutter is provided at the lowest point of the annular drainage channel. The rain gutter has a rectifying grille device, which can quickly drain rainwater from the roof. The grille has a rectifying effect to avoid the formation of excessively large vortices. At the same time, the grille of the rain gutter can block larger debris, so that the drain pipe will not be blocked.

[0052] Embodiment 2

[0053] Combination Figure 3 , which is different from the first embodiment, in the second embodiment, the support member 5 is a vertical rod, which is located on the load-bearing cable 4 and the top end is connected to the connecting cable 6. Compared with the first embodiment, the vertical rod is used as the support member 5, and the membrane surface support structure is more concise and easy to install. Moreover, the vertical rod can avoid the connection node of the orthogonal cable net structure and be directly set on the load-bearing cable 4. With such a configuration, there is no need to redesign the cable clamps at the connection nodes of the orthogonal cable net structure, and only a more conventional cable clamp needs to be used to connect the vertical rod and the load-bearing cable 4.

[0054] Preferably, the connection node between the upright rod and the load-bearing cable 4 is located in the middle of two adjacent stabilizing cables 3, so that the architectural shape formed is more symmetrical and beautiful.

[0055] In summary, the embodiment of the present invention provides a single-layer orthogonal large-opening cable membrane structure. By setting a folded membrane and its supporting structure on a single-layer orthogonal cable net structure, the main force-bearing structure and the membrane structure have clear division of labor, simple force, and at the same time achieve the architectural effect of the folded membrane. In addition, the folded membrane structure naturally forms a drainage ditch, and rainwater is directly discharged from the high area of ​​the roof to the outer ring low area, without the need to set a drainage pipe under the roof, and the architectural effect is guaranteed.

Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
