Description

Technical Field

[0001] The present invention relates to the technical field of adjusting devices, and in particular to a cable adjuster. Background Art

[0002] In the past decade, with the development of domestic sports, the demand for large sports buildings has increased dramatically. At the same time, due to the development of the domestic economy and the improvement of people's material living standards, people pay more and more attention to the beauty of architecture. Traditional architectural forms can no longer meet the aesthetic needs of the public, so in recent years, cable-tensioned structures have gained more and more favor from architects and structural engineers for their lightness and high efficiency. Tensioned structures are different from traditional purely rigid structures. Due to the zero compressive stiffness of the cable, the universality of tensioned structures is far less than that of rigid structures.

[0003] In the actual construction process of buildings such as stadiums, curtain wall cables, roof cable nets, etc. are usually installed after the ring truss construction is completed, and then the curtain wall keels are installed. Among them, the nodes of the roof cable net are equipped with cable clamps for tightening the main cable strands and connecting the main cables to the curtain wall keels. When the roof cable net is tensioned, the curtain wall cables are passively tensioned. When the force is small, the cable clamps clamped at the cable nodes rely on the friction between the cables to resist the unbalanced force. However, since the pressure that the cable can withstand per unit length is limited, when the unbalanced force is large, the control point position of the cable clamp will be offset, resulting in a difference between the actual structure and the theoretical model, leaving safety hazards; at the same time, since the construction and installation sequence of the curtain wall keel is often after the cable tensioning, the construction error caused by tensioning will cause the control point position of the cable clamp to deviate from the theoretical point position, which will lead to the connection between the cable clamp and the curtain wall keel. There are problems such as the ear plate cannot be inserted into the ear plate slot or the pin shaft hole is misaligned and cannot be inserted into the pin shaft. To solve the problem of cable clamp control point offset, a larger friction surface is often required to meet the cable's anti-slip requirements, and a larger contact surface means a larger cable clamp volume, which will undoubtedly increase production costs; in addition, since glass needs to be installed on the outer curtain wall, there will be a large sliding force between the curtain wall keel and the cable. Conventional cable clamps that rely on friction to resist sliding force cannot meet engineering requirements and affect aesthetics. If the curtain wall keel is to be able to absorb the construction errors left over from the previous construction process during construction, it is required that the cable clamp node can adjust its relative position after the cable is tensioned, and at the same time cannot change the internal force of the cable. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects described in the prior art, thereby providing a cable adjuster, which can adjust the spatial point position of the cable clamp without changing the internal force of the cable, eliminate construction errors, effectively transmit the larger sliding force generated by the curtain wall system along the cable length direction, and realize the accurate positioning of the curtain wall system and the roof cable net.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A cable adjuster includes an adjuster body for providing an installation site, wherein both ends of the adjuster body are threadedly connected to an adjusting screw, the free end of each adjusting screw is threadedly connected to an anchor cup, the outer end of the anchor cup is provided with a mounting hole for passing a cable, and the head of the cable is fixedly connected to the free end of the adjusting screw.

[0007] As an implementable manner, both ends of the regulator body are provided with internal threads with opposite thread directions.

[0008] As an implementable manner, the cable adjuster is in a shuttle shape, the anchor cup is a hollow frustum, and the mounting hole is provided on the upper bottom surface of the hollow frustum.

[0009] As an practicable manner, the regulator body has a chamfered surface for reducing weight.

[0010] As an practicable manner, the mounting site includes an ear plate slot opened on the regulator body, the ear plate slot is used to accommodate an external ear plate, and,

[0011] A pin hole is formed through the ear plate slot, and a connecting pin for fixing the external ear plate is arranged in the pin hole.

[0012] As an implementable manner, the installation site also includes cover plates arranged at both ends of the pin shaft hole, and the cover plates are used to limit the connection pin to be located in the pin shaft hole.

[0013] As an practicable manner, the cover plate is fixed to the side surface of the pin shaft by bolts.

[0014] As an implementable manner, a groove is opened on the outer periphery of the pin shaft hole, and the groove is adapted to the pin shaft cover plate to accommodate the pin shaft cover plate.

[0015] As an implementable manner, the cover plate has an internal thread, the connecting pin shaft has an external thread matched with the internal thread, and the cover plate limits the connecting pin shaft through a threaded connection.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The cable adjuster provided by the present invention is mainly composed of an anchor cup, an adjusting screw and an adjuster body, wherein the adjusting screw is used to connect the anchor cup and the adjuster body, and the adjusting screw is threadedly connected to the anchor cup and the adjuster body respectively, and a mounting hole is opened on the anchor cup, and the mounting hole is used to pass the cable, and the end of the cable passes through the mounting hole and enters the inner cavity of the anchor cup, and is connected to the end of the adjusting screw by welding and other methods and built into the anchor cup, that is, the cable is connected to the adjuster body through the anchor cup and the adjusting screw, so that there is no need to make a cable head on the cable, which saves costs. During use, when the cable of the curtain wall is tensioned, the control point of the cable adjuster set on the cable may be misaligned with the target point of the ear connection on the curtain wall, or the connection point on the cable adjuster may be offset. At this time, only the adjuster body or the adjusting screw needs to be rotated to change the relative position of the cable adjuster on the cable and the direction of the connection point, so that the curtain wall keel can be smoothly installed. The structure has good anti-slip force and is convenient for construction.

[0018] Among them, the thread directions of the internal threads at both ends of the two adjuster bodies can be the same or opposite, but when they are the same, one end needs to be adjusted first and then the other end. The feed amount and the tightness of the cable cannot be adjusted at the same time, which leads to inconvenient operation. Therefore, the present application sets the directions of the internal threads at both ends of the adjuster body to be opposite, so that during use, the two adjusting screws can be directly screwed together. At this time, the two adjusting screws rotate in the same direction at the same time. When the adjusting screw at the upper end of the adjuster body is screwed in, the adjusting screw at the lower end of the adjuster is screwed out, or when the adjusting screw at the upper end of the adjuster body is screwed out, the adjusting screw at the lower end of the adjuster body is screwed in, so as to change the relative position and orientation of the cable adjuster on the cable.

[0019] In addition, the cable adjuster of the present application can also be used to connect steel pull rods. When connecting steel pull rods, there is no need to set up connecting screws and anchor cups. It is only necessary to directly connect the external thread at the end of the steel pull rod to the internal thread of the adjuster body. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] See also Figure 1-2The present invention provides a cable adjuster, including an adjuster body 1 for providing an installation site, wherein both ends of the adjuster body 1 are threadedly connected with an adjusting screw 2, the free end of each adjusting screw 2 is threadedly connected with an anchor cup 3, the outer end of the anchor cup 3 is provided with a mounting hole for passing a cable, and the head of the cable 4 is fixedly connected to the free end of the adjusting screw 2.

[0031] See also Figure 2 The cable adjuster provided by the present invention is mainly composed of an anchor cup 3, an adjusting screw 2 and an adjuster body 1, wherein the adjusting screw 2 is used to connect the anchor cup 3 and the adjuster body 1, and the adjusting screw 2 is threadedly connected to the anchor cup 3 and the adjuster body 1 respectively, and a mounting hole is opened on the anchor cup 3, and the mounting hole is used to pass the cable 4, and the end of the cable 4 passes through the mounting hole and enters the inner cavity of the anchor cup 3, and the cable is anchored in the anchor cup 3 by zinc-copper alloy (casting or extrusion, etc.), and the anchor cup 3 and the adjusting screw 2 are connected by threads, the anchor cup 3 is an internal thread, and the adjusting screw 2 is an external thread; one end of the adjusting screw 2 is connected to the anchor cup 3 and the other end is connected to the adjuster body 1, that is, the cable 4 is connected to the adjuster body 1 through the anchor cup 3 and the adjusting screw 2, so that there is no need to make a cable head on the cable 4, saving costs.

[0032] During use, please refer to Figure 1 When the curtain wall cable 4 is tensioned, the control point of the cable adjuster set on the cable 4 may be misaligned with the ear connection target point on the curtain wall keel 5, or the connection point on the cable adjuster may be offset. At this time, it is only necessary to rotate the adjuster body 1 or adjust the screw 2 to change the relative position of the cable adjuster on the cable 4 and the direction of the connection point, so as to smoothly install the curtain wall keel 5. This structure has good anti-slip force and is easy to construct.

[0033] Among them, see Figure 2-3, the two ends of the regulator body 1 are respectively provided with internal threads, and the thread directions of the internal threads at the two ends of the regulator body 1 can be the same or opposite, but when they are the same, it is necessary to adjust one end first and then adjust the other end. It is impossible to adjust the feed amount and the tightness of the cable at both ends at the same time, which has the problem of inconvenient operation. Therefore, the application sets the directions of the internal threads at both ends of the regulator body 1 to be opposite, so that during use, the two adjustment screws 2 can be directly screwed. At this time, the two adjustment screws 2 rotate in the same direction at the same time. When the screw 2 is rotated clockwise (for example), the screw 2 and the anchor cup 3 and the regulator 1 are screwed in or screwed out at the same time; and when the other adjustment screw 2 is also rotated clockwise, it is screwed out or screwed in at the same time, and its action response is opposite to the action direction of the adjustment screw 2 described above, so that when the upper adjustment screw 2 is adjusted to reduce the spacing, the spacing of the lower adjustment screw 2 is increased; or when the upper one is increased, the lower one is reduced, so that the cable length remains unchanged when the adjustment screw 2 is adjusted, so the cable force will not change, that is, the relative position and orientation of the cable regulator on the cable 4 are changed under the premise that the cable force remains unchanged.

[0034] Specifically, see Figure 2-3 The cable adjuster in the present application is shuttle-shaped, the anchor cup 3 is a hollow truncated cone, and the mounting hole is provided on the upper bottom surface of the hollow truncated cone. The upper bottom surface here refers to the truncated cone in the popular sense. As is known to all, the truncated cone has the straight line where the waist of the right-angled trapezoid perpendicular to the bottom side is located as the rotation axis, and the geometric body surrounded by the curved surface formed by the rotation of the other sides is called a truncated cone. The rotation axis is called the axis of the truncated cone. The circular surface formed by the rotation of the upper and lower bases of the right-angled trapezoid is called the upper and lower bottom surfaces of the truncated cone, and the curved surface formed by the rotation of the other waist is called the side surface of the truncated cone. The waist of the right-angled trapezoid at each position on the side surface is called the generatrix of the truncated cone. The length of the waist of the trapezoid on the axis of the truncated cone is called the height of the truncated cone, and the height of the truncated cone is also the distance between the upper and lower bottom surfaces. The truncated cone can also be considered as the part of the cone cut by the two perpendicular planes of its axis, so it can also be called a "truncated cone". Trapezium refers to a quadrilateral with one set of parallel opposite sides and another set of non-parallel opposite sides. The two parallel sides are called the bases of the trapezoid, the longer base is called the lower base, and the shorter base is called the upper base. The two non-parallel sides are called waists; the vertical line segment between the two bases is called the height of the trapezoid. A trapezoid with one waist perpendicular to the base is called a right-angled trapezoid. Therefore, the upper base surface of the present application refers to the base surface with a smaller diameter in the truncated cone. In the present application, not only is the cable adjuster in the shape of a shuttle as a whole, but the adjuster body 1 is also in the shape of a shuttle. This not only reduces the dead weight, but also makes the shuttle-shaped lines more beautiful and saves steel. Of course, in order to further save steel, the two side surfaces of the adjuster body 1 can also be flattened to form a flat surface.

[0035] In this example, see Figure 2-3The installation site includes an ear plate slot 11 opened on the regulator body 1, and a pin hole 12 opened through the ear plate slot 11. The pin hole 12 is used to install a connecting pin 13. It is best to open the ear plate slot 11 from the side of the regulator body 1, and the pin hole 12 is set on the cut plane. When in use, first insert the external ear plate, such as the ear plate on the curtain wall keel 5, into the ear plate slot 11, and then pass the connecting pin 13 through the pin hole 12 and the hanging hole on the ear plate in turn, and then fix it in the pin hole 12. There are two ways to fix the connecting pin 13. One is to set a cover plate 14 at both ends of the pin hole 12, and the cover plate 14 limits the connecting pin 13 in the pin hole 12, and then fix the cover plate 14 to the side of the pin 13 by a bolt 15, and then fix the connecting pin 13 in the pin hole 12. Of course, for the convenience of installation and for a more beautiful appearance, a groove (not shown in the figure) can be opened on the outer periphery of the pin shaft hole 12, and the shape of the groove is adapted to the cover plate 14. When the cover plate 14 is used to fix the connecting pin shaft 13, the cover plate 14 is first placed in the groove to achieve pre-positioning, and then the bolt 15 is installed on the side of the connecting pin shaft 13 to achieve limiting positioning; secondly, an internal thread is opened in the cover plate 14, and the connecting pin 13 has an external thread adapted to the internal thread. The connecting pin 13 is fixed in the pin shaft hole 12 through the cover plates 14 at both ends.

[0036] Of course, the structure of the cable adjuster of the present application can not only connect the cable, but also be used to connect the steel pull rod. When connecting the steel pull rod, there is no need to set the adjusting screw 2 and the anchor cup 3. It is only necessary to directly connect the external thread of the end of the steel pull rod to the internal thread of the adjuster body 1.

[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
