Description

Technical Field

[0001] This invention relates to the field of cable clamps for glass curtain walls, and in particular to a cable clamp structure and clamp with a support arm. Background Technology

[0002] In cable-stayed wall systems (such as single-cable wall structures), the cable clamps are the core components connecting the vertical cables and the glass panels. The vertical dead load and horizontal load of the glass are transferred to the cable system through the clamps. The structural rationality of transferring the vertical dead load of the glass to the vertical cables directly affects the safety and aesthetics of the entire system. Currently, existing cable-stayed wall systems generally use four screws in two rows (top and bottom) to fix the clamps to the cables. Because there is a certain distance between the glass dead load and the vertical cables, the glass dead load exerts an eccentric bending moment on the vertical cables. Since the vertical cables are flexible structures, this eccentric load causes the glass to tend to sag relative to the cables. The force couple formed by the two rows of screws is needed to resist the eccentric bending moment generated by the glass dead load.

[0003] However, the aforementioned traditional cable clamps have obvious drawbacks: First, the four-bolt structure requires four bolt mounting positions to be reserved on the clamp, and the clamp size is large, affecting the high transparency requirements of cable curtain walls in architectural scenarios; Second, the large clamp size makes it impossible to reduce the weight of the clamp, increasing building material consumption; Third, most cable clamps are made of stainless steel, which has a high thermal conductivity, and the excessively large clamp size will increase the heat transfer coefficient of the entire curtain wall, increasing building energy consumption.

[0004] Therefore, providing a cable clamp structure and clamp that is compact in size and can effectively reduce building material and energy consumption can effectively solve the shortcomings of the existing technology. Summary of the Invention

[0005] To address the problems of traditional cable clamps, such as their size and weight, low installation efficiency, and high building energy consumption due to their double-row, four-bolt structure, this application provides a curtain wall cable clamp structure and cable clamp with a support arm.

[0010] Furthermore, provided that aesthetic requirements and allowable bending strength of the material are met, the thickness of the support arm at its root must not be less than T. min ;T min The calculation formula is as follows: Wherein: T min : indicates the minimum thickness of the support arm at its root; F g : represents the design value of the glass self-weight load acting on the clamp; L1: horizontal eccentricity distance from the point of application of the glass self-weight to the center of the cable; L2: vertical distance from the parallel bolts to the farthest end of the support arm; L3: design arm length of the support arm; σ s : Allowable bending strength of the support arm material; d: Cable diameter.

[0011] Preferably, the front cable pressure block 3 and the rear cable pressure block 4 have the same cross-sectional shape and size, both being elliptical, and their cross-sectional dimensions are smaller than those of the connecting plate 2.

[0012] A lightweight quick-release cable clamp includes the clamp structure of claim 1, a cover plate 6, and a rotating ball hinge assembly 7; the cover plate 6 is bolted to the cable front pressure block 4, a glass panel is mounted on the glass support plate 1 between the two, and the rotating ball hinge assembly 7 is provided between the cover plate 6 and the outer side of the glass panel, and between the connecting plate and the inner side of the glass panel; spherical recesses matching the rotating ball hinge assembly 7 are provided on the cover plate 6 and the connecting plate 2.

[0013] Furthermore, the glass support plate 1 includes a horizontal support plate 11 and a vertical support plate 12; the horizontal support plate 11 has a strip groove on the side facing the cover plate, and the cover plate 6 has a matching strip protrusion; after the cover plate 6 is connected to the connecting plate 2, the protrusion is inserted into the groove to engage with it.

Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Example 1 This embodiment discloses a curtain wall cable clamp structure with a support arm, referring to... Figure 1It includes a glass support plate 1, a connecting plate 2, and a cable fixing block; wherein, the cable fixing block includes a front cable fixing block 3 and a rear cable fixing block 4; the front cable fixing block 3 and the rear cable fixing block 4 are bolted together; a support arm 5 is provided directly below the center of the front cable fixing block 3; The glass support plate 1, the support arm 5, and the two parallel bolts together form a stable load-bearing structure for the curtain wall cable clamp with the vertical cable. The self-weight generated by the glass panel on the glass support plate 1 is transmitted to the cable through the force couple formed by the support arm 5 and the upper row of bolts. This is equivalent to the traditional solution that uses the force couple formed by the upper and lower rows of four bolts to resist bending moment.

[0021] Reference Figure 1 The glass support plate 1 includes a horizontal support plate 11 and a vertical support plate 12. The horizontal support plate 11 and the vertical support plate 12 are centrally located on the connecting plate 2 and are rectangular strips with a break at the center to allow connecting bolts to pass through. The size of the glass support plate 1 is determined according to the size of the connecting plate 2 and the thickness of the curtain wall glass panel. For aesthetic purposes, the outer edge of the glass support plate 1 is aligned with the outer edge of the connecting plate 2. The horizontal support plate 11 is used to support the weight of the glass panel, and the vertical support plate 12 is used to position the glass installation and can also transfer horizontal seismic loads to the cables. The connecting plate 2 is connected to the glass support plate 1 on one side and the cable front pressure block 3 on the other side; in this embodiment, the glass support plate 1, the connecting plate 2 and the cable front pressure block 3 are integrally formed. Both the front cable pressure block 3 and the rear cable pressure block 4 have a semi-circular continuous cable groove on one side center that matches the vertical cable. The front cable pressure block 3 and the rear cable pressure block 4 have the same cross-sectional shape and size. Their shape is preferably the smallest possible while ensuring that the contact area with the cable after the two are connected meets the load-bearing requirements and that two screw holes are reserved on both sides of the cable groove. In this embodiment, both the front cable pressure block 3 and the rear cable pressure block 4 are elliptical, and their cross-sectional dimensions are smaller than those of the connecting plate 2. The center of the cable rear pressure block 4, which is not in the cable groove position, has a pressure block screw hole on each side. The pressure block bolt passes through the pressure block screw hole and is bolted to the cable front pressure block 3, and the two are tightly fitted and fixed to the vertical cable. In this embodiment, the pressure block bolt is an M16*35 internal hex countersunk machine screw. One end of the support arm 5 is flush with the semi-circular continuous cable groove, and the other end extends towards the connecting plate 2. The support arm 5 has a variable cross-section, with an arm length of L, an arm width of W, and an arm thickness of T. At the end that is in contact with the cable, the support arm 5 gradually tapers from the root to the end through rounded corners, and the arm width W gradually decreases accordingly. In the direction away from the cable, the arm length L gradually decreases, while the arm thickness T gradually increases. The design values ​​of the arm length L, arm width W, and arm thickness T of the support arm 5 need to take into account both aesthetics and its load-bearing strength. In terms of aesthetics, the edge of the support arm 5 can be aligned with the lower edge of the connecting plate 2, and the arm width can be equal to the cable diameter d, so that the support arm 5 can be visually hidden when viewed from the front. In terms of load-bearing strength, the material of the support arm 5 must meet its allowable bending strength.

[0022] Reference Figure 2 The design value of the glass self-weight load acting on the cable clamp structure is F. g The horizontal eccentricity distance from the point of application of the glass's self-weight to the center of the cable is L1; the vertical distance from the parallel bolts to the farthest end of the support arm 5 is L2; ​​the concentrated load force on the farthest end of the support arm 5 is F1; the section modulus of the support arm end is W; the stress magnitude at the root of the support arm 5 is σ; the allowable bending strength of the material of the support arm 5 is σ. s The cable diameter is d.

[0023] While ensuring aesthetics, the arm length of the support arm 5 is L3, and the width at the root is equal to the cable diameter d. Based on this, the stress on the support arm 5 can be checked, and its minimum wall thickness T at the root can be clearly obtained. min ;T min The calculation formula is as follows: In this embodiment: F g =7.2KN, L1=100mm, L2=48mm, L3=18mm, d=38mm, σ s =178MPa; Calculate T min =15.5mm, that is, under the premise of ensuring aesthetics and allowable bending strength of materials, the thickness of the root arm 5 shall not be less than 15.5mm.

[0024] Provided that the arm length L and arm width W of the support arm 5 meet the aesthetic requirements and the arm thickness T meets the minimum arm thickness, the cross-sectional dimensions of the support arm 5 can be adjusted according to the actual situation. However, it is best to consider that the allowable bending strength of the material of the support arm 5 is within a safe range for the most economical approach.

[0025] In this embodiment, the arm 5 is designed with a length of 18mm, a width of 30mm at the base, a width of 9mm at the end, a thickness of 36mm at the base, and a thickness of 10mm at the end.

[0026] The variable cross-section design dimensions of the support arm 5 described in this embodiment need further verification to determine whether they meet the material stress requirements. When σ / σ s When the value is less than 1, the material of the support arm 5 can be considered to meet the stress requirements. Stress analysis shows that: F g × L1 = F1 × L2 The stress at the root of the fifth support arm is: σ = F1 × L3 / W In this embodiment: W=6480mm 3 The calculated value is σ = 41.67 MPa. Therefore, verify σ / σ s <1 is true, meaning that the variable cross-section design dimensions of the support arm 5 meet the stress requirements of the material.

[0027] Based on the above calculations and verifications, this embodiment, through the technical solution of setting the variable cross-section support arm 5 on the cable front pressure block 3, can reduce the number of bolts connecting the cable front pressure block 3 and the cable rear pressure block 4 from four in a double row to two in a single row, while still meeting the stress requirements; the load generated by the horizontal wind can be transferred to the cable structure through a row of bolts, and the self-weight generated by the glass can be transferred to the cable structure through the force couple formed by the support arm 5 and the upper row of bolts, thus fully achieving the effect of the original two rows of transverse bolts.

[0028] Example 2 Reference Figure 3 This embodiment is basically the same as the first embodiment in structure. The only difference is that the support arm 5 is bolted to the cable front pressure block 3, and the support arm 5 only changes in thickness, while the arm length and arm width remain unchanged.

[0029] In this embodiment, the support arm 5 is an L-shaped angle bracket, divided into a connecting part and a support arm part; the connection between the connecting part and the cable front pressure block 3, and the connection between the support arm part and the vertical cable are all treated with a chamfered arc, so that the connecting part is tightly attached to the cable front pressure block 3 by two support arm bolts, and the support arm part is tightly attached to the vertical cable; the support arm bolt is an M6*25 countersunk machine bolt.

[0030] In this embodiment: F g =3.2KN, L1=120mm, L2=70mm, L3=30mm, d=28mm, σ s =178MPa; T is calculated according to the formula. min =14.1mm, meaning that the thickness of the support arm at the base of the fifth arm shall not be less than 14.1mm.

[0031] Similarly, in this embodiment, the cross-sectional dimensions of the support arm 5 are most economical and optimal while ensuring aesthetics and keeping the allowable bending strength of the material within a safe range.

[0032] In this embodiment, the support arm 5 is designed with a length of 30mm, a width of 28mm, a thickness of 15mm at the root, a thickness of 10mm at the end, and a cable diameter d of 28mm; (Refer to...) Figure 3-4 In this embodiment, although the edge of the support arm 5 extends beyond the lower edge of the connecting plate 2, the sealant gap between the glass panels can completely cover the support arm 5, thus satisfying the aesthetic requirements.

[0033] In this embodiment, W=1048mm 3 The calculated value is σ = 157.44 MPa; σ / σ s If <1 is true, the cross-sectional design dimensions of the support arm 5 meet the material stress requirements.

[0034] Since the support arm 5 in this embodiment is connected by bolts, it is also necessary to check whether the shear bearing capacity of the support arm bolts meets the requirements. In this embodiment, the shear bearing capacity of a single bolt is V. x =5.3KN, when 2V x When F1 > 2V, it can be determined that the requirements are met. Calculate F1 = 5.49 kN; 2V x If F1 is met, the support arm bolts meet the shear bearing capacity requirements.

[0035] After calculation and verification, the technical solution in this embodiment, in which the support arm 5 is connected to the cable front pressure block 3 by bolts, can also reduce the number of bolts connecting the cable front pressure block 3 and the cable rear pressure block 4 from four in a double row to two in a single row, while still meeting the force requirements. This embodiment has limited applicability compared to Embodiment 1, but it is less difficult and less expensive to manufacture.

In this embodiment, the cover plate 6 is elliptical frustum-shaped, and the shape and size of its largest plane are the same as those of the connecting plate 2.

[0037] Reference Figure 5-8The transverse support plate 11 has a strip-shaped groove at one end facing the cover plate; the connecting plate 2 has a spherical recess that matches the rotating ball joint assembly 7; the inner side of the cover plate 6 has a spherical recess that matches the rotating ball joint assembly 7 and a protruding plate that engages with the strip-shaped groove on the transverse support plate 11. When the two are connected, the protruding plate can be inserted into the strip-shaped groove to limit its rotation relative to the cable clamp structure during installation; in this embodiment, the cover plate bolt is an M12*85 internal hexagon countersunk machine screw; The rotating ball hinge assembly 7 consists of two nylon sheets, shaped like the cover plate 6 and the connecting plate 2, with their outer edges not exceeding the outer edges of the cover plate 6 and the connecting plate 2. Four spherical protrusions are symmetrically arranged on one side, which can respectively fit tightly with the spherical recesses provided on the cover plate 6 and the connecting plate 2 to accommodate the rotation of the glass panel relative to the cable clamp structure. The rotating ball hinge assembly 7 is provided with openings, allowing the cover plate bolts to pass through. One bolt can pass through the protrusion on the cover plate 6 and fit with the cover plate 6, while the other bolt can pass through the glass support plate 1 and fit with the connecting plate 2.

[0038] In this embodiment, weather-resistant sealant is injected at the edges of the cable clip, glass panel, cover plate 6, and connecting plate 2 to ensure the airtightness and watertightness of the system; silicone weather-resistant sealant can be injected between the glass panels on both sides; to ensure structural safety, silicone weather-resistant sealant can also be injected on the outdoor side and silicone structural sealant can be injected on the indoor side.

[0039] The installation process of the cable clip in this embodiment is as follows: 1. Secure the front clamping block 3 and the rear clamping block 4 to the vertical cable with two bolts, and make the support arm 5 abut against the vertical cable; 2. Pass a nylon sheet of the rotating ball joint assembly 7 through the glass support plate 1, so that its spherical protrusion matches the notch provided on the connecting plate 2; 3. Install the glass panel on the horizontal support plate 11, and position the glass panel using the vertical support plate 12; 4.

Secure the cover plate 6 to the connecting plate 2 with bolts; 6. Apply weather-resistant sealant to the edges of the cover plate 6 and connecting plate 2 to meet the curing requirements.

[0040] 7. Apply weather-resistant sealant between the glass panels on the exterior side and apply silicone structural sealant between the glass panels on the interior side, and meet the maintenance requirements.

Vertical load: The glass dead load is transmitted to the cable structure through the force couple formed by the support arm 5 and the two parallel screws connecting the front cable pressure block 3 and the rear cable pressure block 4.
