Description

Technical Field

[0001] The utility model relates to the technical field of building cable-membrane structures, in particular to a cable-membrane connection structure. Background Art

[0002] Cable-membrane structures, favored by structural engineers and architects for their lightness and flexibility, balance structural and architectural requirements, and are widely used in large-span structures. A cable-membrane structure is a spatial curved surface covering formed by tensioning high-strength membrane material and cables. The prestressed cables and membranes share the responsibility of bearing external loads, making the connection between them crucial.

[0003] The connection point between the cable and the membrane is often a complex spatial curve. The traditional connection method is to connect the membrane materials on both sides to the cable through staggered U-shaped clamps, and then weld the waterproof membrane at high altitude on site to cover the connection gap.

[0004] However, welding waterproof membranes at high altitudes is difficult, with uneven membrane surfaces and poor weld tightness. This can also lead to heat failure of the main membrane welds, resulting in high installation risks and difficult subsequent maintenance. Furthermore, the bare surface of the waterproof membrane cannot accommodate the lifeline channels that accompany the membrane, nor can it be fitted with auxiliary functional accessories such as lightning protection and lighting. Furthermore, hot-melt welding of waterproof membranes to different membrane materials is not feasible, and this method of covering and shielding is even more difficult when the membrane materials on either side of the cable are of different types. Leaving the gap between the cable and the membrane uncovered can lead to a sudden increase in local wind loads, causing local damage to the membrane surface, and widespread water leakage, rendering the waterproofing function ineffective.

In addition, directional terms such as above, below, up, down, upward, downward, left, right, etc. are used relative to the exemplary embodiments as they are shown in the figures, with the upward or upper direction toward the top of the corresponding figure, and the downward or lower direction toward the bottom of the corresponding figure.

[0032] The purpose of the present invention is to provide a cable-membrane connection structure to solve the problem that the existing cable-membrane connection requires high-altitude welding of the waterproof membrane.

[0033] Please refer to Figures 1 to 5 An embodiment of the utility model provides a cable-membrane connection structure, which includes: a column segment 1, a central cable 2, two membrane materials 3, and two fixing cables 4; the column segment 1 has a central cable channel 11 and two membrane grooves 12, and the two membrane grooves 12 are opened opposite to each other perpendicular to the axial direction of the column segment 1, and the central cable channel 11 and the membrane grooves 12 are respectively passed through the axial direction of the column segment 1; the central cable 2 is inserted into the central cable channel 11, and the two fixing cables 4 are respectively inserted into the two membrane grooves 12, and the cross-sectional size of the fixing cables 4 is larger than the opening size of the membrane grooves 12; each of the membrane materials 3 is fixed to itself after passing through one of the fixing cables 4.

[0034] In an alternative exemplary embodiment, the membrane groove 12 includes an enlarged portion 121 and an opening 122, wherein the cross-sectional shape of the enlarged portion 121 is larger than the cross-sectional shape of the fixing cable 4, so that the fixing cable 4 can be moved along the axial direction ( Figure 2 The cross-sectional dimension of the fixing rope 4 is larger than the dimension of the opening 122, so the fixing rope 4 cannot move in the radial direction ( Figure 2 The membrane 3 is secured to the column segment 1 (e.g., by welding) after passing through the retaining cable 4. The membrane 3 is effectively fixed to the column segment 1 along the tensioning direction (i.e., perpendicular to the column segment 1). However, the membrane 3 and retaining cable 4 can move axially along the column segment 1 without restriction, facilitating installation.

[0035] The central cable channel 11 of the column segment 1 is preferably arranged along the axis of the column segment 1, that is, the central cable channel 11 is located at the centroid of the cross section of the column segment 1. The central cable 2 is inserted into the central cable channel 11 to ensure the balance of the tension applied by the two membranes 3.

[0036] With such a configuration, the provision of an axially through-going membrane groove 12 on the column segment 1 allows two membrane materials 3 to be directly connected to the column segment 1, thereby avoiding the gap caused by the provision of a U-shaped clamp in the prior art, thereby avoiding the step of high-altitude welding of the waterproof membrane, effectively reducing the labor consumed on the construction site, and is particularly suitable for fully assembled installation, which is convenient for construction. The cable-membrane connection structure provided by the utility model has good airtightness and excellent waterproofing effect on the one hand; on the other hand, since no additional welding of the waterproof membrane is required, the appearance of the entire membrane material 3 is more complete and beautiful. In addition, since the two membrane grooves 12 are independent of each other, they can also be adapted to the connection of two different membrane materials 3. That is, the materials of the membrane materials 3 connected on both sides of the same column segment 1 can be the same or different, which greatly improves the scope of application of the cable-membrane connection structure provided by this embodiment.

[0037] Optionally, the cable-membrane connection structure includes a plurality of column segments 1, each of which has a length of 0.2m to 2m, and the plurality of column segments 1 are arranged in sequence along a straight line or curve in an axial direction. In the application of cable-membrane structures, it is often necessary to form a spatial curved surface, which requires the central cable 2 to often extend along a complex spatial curve. In order to form such a spatial curve shape, if a whole-length column segment 1 is used, the column segment 1 must also bend and extend along the spatial curve, which has an adverse effect on manufacturing, assembly, and subsequent displacement and deformation caused by cable-membrane tensioning and bearing loads. Based on this, the cable-membrane connection structure provided in this embodiment includes a plurality of column segments 1, and the plurality of column segments 1 are arranged in sequence in an axial direction, can be straight or curved, and is suitable for different spatial curves, and is suitable for changes in curvature under load, and is suitable for structural errors and various deformations.

[0038] Considering the ease of assembly and the effectiveness of curve fitting, the length of each column segment 1 can be selected to be 0.2m to 2m, preferably 0.3m to 0.6m, for example, 0.4m, 0.5m, etc. It should be understood that the lengths of multiple column segments 1 can be uniform or different, for example, shorter lengths can be selected in areas with greater curvature, while longer lengths can be selected in areas with less curvature. Furthermore, rubber pads can be placed between adjacent column segments 1 to reduce extrusion and friction between the segments 1.

[0039] Furthermore, the arrangement of multiple column segments 1 also facilitates fully assembled construction and subsequent maintenance. Multiple column segments 1 can be spliced ​​together at high altitude without the need for large cranes or other equipment. During subsequent maintenance, one or more column segments 1 can also be easily installed, replaced, or removed.

[0040] Optionally, the outer contour of the cross section of the column segment 1 is circular, elliptical or polygonal (preferably a regular polygon). Such a cross-sectional shape can form central symmetry or similar to central symmetry, which is beneficial to improving the uniformity of force when the two membrane materials 3 are stretched, and is more beneficial to minimizing the size of the cross section while meeting the functional and structural strength requirements, which is beneficial to optimizing the structural layout and ensuring the appearance effect.

[0041] Please refer to Figure 5 Optionally, the fixing rope 4 is movably arranged in the film groove 12; the opening 122 of the film groove 12 allows the direction of the connection line between the film material 3 and the two film grooves 12 ( Figure 5 The angle α formed by the two membrane materials 3 (in the horizontal direction) is 0°~30°. In the application of cable-membrane structures, it is often necessary to form a spatial curved surface, which makes the two membrane materials 3 on both sides of the column segment 1 often form a certain angle, rather than extending on the same plane. In addition, after the cable membrane is tensioned and bears load, the angle between the two membrane materials 3 may also change to a certain extent. In order to eliminate the angle change between the two membrane materials 3, this embodiment allows the fixing cable 4 to be movably set in the membrane groove 12, and the opening 122 of the membrane groove 12 has a certain width, thereby allowing the tensioning direction of the membrane material 3 and the direction of the line connecting the two membrane grooves 12 to change to a certain extent.

[0042] Optionally, the column segment 1 includes a first column 13 and a second column 14; the two membrane slots 12 are provided on the first column 13, and the first column 13 and the second column 14 are detachably connected in a direction perpendicular to a line connecting the two membrane slots 12. In some embodiments, to facilitate installation, the column segment 1 is radially divided into two components, the first column 13 and the second column 14.

[0043] Please refer to Figures 2 to 4 Optionally, the first column 13 has a direction perpendicular to the line connecting the two membrane slots 12 ( Figure 2 The first central groove 131 is opened in the vertical direction, and the second column 14 has a direction perpendicular to the line connecting the two membrane grooves 12 ( Figure 3 The second central groove 141 is opened in the vertical direction. When the first column 13 and the second column 14 are connected, the opening of the first central groove 131 and the opening of the second central groove 141 are opposite to each other and enclose the central cable channel 11. Figure 4As shown. In the actual engineering application installation process, the center cable 2 can be stretched and laid out first, and then the first column 13 and the second column 14 can be surrounded on the center cable 2 through the first center groove 131 and the second center groove 141, thereby fixing the first column 13 and the second column 14. With such a configuration, the center cable 2 does not need to be installed by axial penetration, which is convenient for assembly at high altitudes. It can be understood that the shape formed by the first center groove 131 and the second center groove 141 should be compatible with the cross-sectional shape of the center cable 2, and preferably be able to clamp the center cable 2.

[0044] In one embodiment, the first column 13 has a bolt through hole and a tool operation hole 132, and the second column 14 has a T-slot 142; the bolt through hole is opened in a direction perpendicular to the line connecting the two membrane slots 12, and the tool operation hole 132 is coaxial with the bolt through hole and is opened at the end of the bolt through hole away from the second column 14 ( Figure 4 The T-slot 142 is formed through the axial direction of the second column 14 to allow the bolt 51 or the nut 52 to penetrate axially and limit the rotation of the bolt 51 or the nut 52; when the first column 13 and the second column 14 are connected, the bolt penetration hole is aligned with the T-slot 142 to allow the bolt 51 to penetrate and be fixed.

[0045] The first column 13 and the second column 14 can be fastened together using a bolt 51 and a nut 52. Since the first column 13 and the second column 14 are joined in a direction perpendicular to the line connecting the two membrane slots 12, bolt holes extending in this direction can be provided for the passage of the bolts 51. It is understood that the inner diameter of the bolt holes can be slightly larger than the outer diameter of the threaded section of the bolts 51 to facilitate the passage of the bolts 51.

[0046] The bolt 51 and nut 52 can be matched in two ways: positive and negative. Figure 4 In one embodiment, the bolt 51 is inverted, with the head of the bolt 51 placed in the T-slot 142, and the threaded section of the bolt 51 is passed upward through the bolt hole, and the nut 52 is screwed into the threaded section to achieve tightening. In another embodiment, the bolt 51 can be placed upright, the nut 52 is placed in the T-slot 142, and the bolt 51 is passed through the bolt hole from the side of the first column 13 and screwed into the nut 52 to achieve tightening.

[0047] Optionally, the cable-membrane connection structure further includes a bolt 51 and a nut 52; the bolt 51 is a hexagonal bolt, whose hexagonal bolt head 511 is movably inserted into the T-slot 142 along the axial direction of the second column 14 and is restricted from rotation by the T-slot 142; the threaded section 512 of the bolt 51 passes through the bolt insertion hole; the nut 52 is sleeved on the threaded section 512 of the bolt 51 through the tool operation hole 132, and the tool operation hole 132 is used to allow a tightening tool to pass through to rotate the nut 52. The method of placing the hexagonal bolt upside down in the T-slot 142 facilitates the insertion of the bolt insertion hole of the first column 13 during installation, which is more convenient for installation than the method of placing the nut 52 in the T-slot 142. The method of placing the nut 52 in the T-slot 142 requires positioning and aligning the nut 52 with the bolt insertion hole, which is somewhat difficult.

[0048] In an alternative embodiment, the T-slot 142 includes a rotation-limiting section 143 and an opening section 144. The cross-sectional width of the rotation-limiting section 143 matches the width (the width across the hexagonal sides) of the hexagonal head 511 of the bolt 51 or the nut 52. This restricts the rotation of the bolt 51 or nut 52 after the hexagonal head 511 of the bolt 51 or the nut 52 slides into the T-slot 142 axially. Specifically, the bolt 51 or nut 52 can only move axially along the T-slot 142. The cross-sectional width of the opening section 144 matches the outer diameter of the threaded section 512 of the bolt 51. The cross-sectional width of the opening section 144 can be slightly larger than the outer diameter of the threaded section 512 to facilitate the passage of the threaded section 512. It will be appreciated that the opening section 144 faces the first column 13, while the rotation-limiting section 143 is located on the side of the opening section 144 away from the first column 13.

[0049] The size of the tool operation hole 132 is related to the tightening tool used. Figure 4 In the illustrated configuration, a hexagon socket is typically used to tighten the nut 52. In this case, the diameter of the tool operation hole 132 is not less than the outer diameter of the hexagon socket. In other embodiments, for example, when the nut 52 is positioned in the T-slot 142, a hexagon socket bolt can be used as the bolt 51. In this case, the tool operation hole 132 only needs to allow the passage of an hexagonal wrench, so the diameter of the tool operation hole 132 can be relatively smaller.

[0050] Preferably, the first column 13 has at least two bolt holes and at least two tool holes 132, and the second column 14 has two T-slots 142. The at least two bolt holes are symmetrically arranged on either side of the central cable passage 11 along the line connecting the two membrane slots 12, with the tool holes 132 corresponding to the bolt holes one-to-one. The two T-slots 142 are symmetrically arranged on either side of the central cable passage 11 along the line connecting the two membrane slots 12. It will be appreciated that having two sets of bolt 51 and nut 52 locking mechanisms on either side of the central cable passage 11 facilitates balanced locking force and improves locking reliability. The two T-slots 142 extend axially through the second column 14, while the number of bolt holes and tool holes 132 can be adjusted based on the axial length of the first column 13. When the axial length of the first column 13 is short, only two bolt holes and only two tool holes 132 can be provided. Preferably, when the axial length of the first column 13 is long, the number of bolt holes and the number of tool operation holes 132 can be multiple, and preferably an even number of them are arranged in pairs. Each pair of bolt holes is arranged at the same axial position of the first column 13.

[0051] Optionally, the column segment 1 has an equipment slot 15 radially extending therefrom, the opening of the equipment slot 15 being perpendicular to the direction of the line connecting the two membrane slots 12. The equipment slot 15 can, for example, be radially extending on the first column 13 and / or the second column 14, with its opening facing outward. It can be used to install ancillary equipment such as lightning protection, maintenance access, sprinklers, lighting, and photovoltaic lines. In an alternative exemplary embodiment, the cross-section of the equipment slot 15 is T-shaped, and its cross-section can, for example, be consistent with the notch of a general industrial aluminum profile, thereby being adaptable to installation using standard fasteners of various industrial aluminum profiles.

[0052] In summary, the cable-membrane connection structure provided by the present invention includes a column section, a center cable, two membrane materials, and two fixing cables; the column section has a center cable channel and two membrane grooves, the two membrane grooves are opened perpendicular to the axial direction of the column section and opposite to each other, and the center cable channel and the membrane grooves are respectively passed through along the axial direction of the column section; the center cable is inserted into the center cable channel, and the two fixing cables are respectively inserted into the two membrane grooves, and the cross-sectional dimensions of the fixing cables are larger than the opening dimensions of the membrane grooves; each membrane material is fixed to itself after passing through one of the fixing cables. With such a configuration, the provision of the axially extending membrane grooves on the column section allows two membrane materials to be directly connected to the column section, avoiding the gap caused by the U-shaped clamps in the prior art, thereby avoiding the step of high-altitude welding of waterproof membranes, effectively reducing the labor consumed on the construction site, and is particularly suitable for fully assembled installation and is easy to construct. The cable-membrane connection structure provided by the present invention has good airtightness and excellent waterproofing effect on the one hand; on the other hand, since no additional welding of waterproof membrane is required, the appearance of the entire membrane material is more complete and beautiful. In addition, since the two membrane tanks are independent of each other, they can also be adapted to the connection of two different membrane materials.

[0053] It should be noted that the above embodiments can be combined with each other. The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes or modifications made by ordinary technicians in the field of the present invention based on the above disclosure are within the scope of protection of the present invention.
