Description

Technical Field

[0001] The invention belongs to the field of bridges, and in particular relates to a freely rotatable decorative inclined cable anchoring device. Background Art

[0002] In bridge construction, aesthetics is increasingly valued. In addition to the practical functions of a bridge, its exterior design has gradually become an important factor in evaluating a bridge. Using cable-stayed cables for exterior decoration is a common technique in modern bridge construction. It not only provides additional support and stability, but also adds a sense of modernity and artistry to the bridge. In design, decorative cable-stayed cables generally do not participate in stress bearing and are only used for decorative purposes. The cable force is much smaller than that of conventional cable-stayed cables.

[0003] In the prior art, a common practice for anchoring the decorative stay cable to the main beam is to cast or pre-embed an anchor block outside the main beam or guardrail, and then anchor the decorative stay cable to the anchor block.

[0004] The problems with the existing technology are: due to the consideration of shape, the angle between the cable and the main beam is generally different, resulting in the disadvantages of inconsistent anchor surface angles, diversified anchor block sizes, a large number of high-altitude dangerous operations, and difficult positioning. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a freely rotatable decorative inclined cable anchoring device.

[0006] The technical solution adopted by the present invention is: a freely rotatable decorative inclined cable anchoring device, comprising an anchoring mother, an anchoring sub-tube, an L-shaped gasket, and a hexagonal nut; the anchoring mother tube is pre-buried in the main beam or guardrail; the anchoring sub-tube is inserted into the anchoring mother tube, and after being fixed, it can be freely rotated to adapt to any installation angle of the decorative inclined cable along the bridge (such as Figure 7 shown).

[0007] Preferably, the anchoring mother cylinder has a round steel cylinder body, one end of which is welded with a mother cylinder bottom sealing plate for sealing, and the other end is welded with a stiffening ring to form a semi-open cylindrical cylinder, cylindrical head nails are welded around the outer wall of the mother cylinder body, and lubricating oil is applied to the inner wall of the anchoring mother cylinder.

[0008] Preferably, the stiffening ring is provided with stiffening ribs and bolt holes at intervals, and the embedded bolt sleeves are arranged concentrically with the bolt holes and welded to the stiffening ring.

[0009] Preferably, the anchoring sub-tube has a circular steel tube body, the left end is welded with an inner sealing plate for sub-tube sealing, and the right end is welded with an end sealing plate for sub-tube sealing. The diameter of the inner sealing plate for sub-tube is slightly smaller than the inner diameter of the sub-tube body, and the diameter of the end sealing plate for sub-tube is larger than the outer diameter of the sub-tube body.

[0010] Preferably, the diameter of the anchoring mother cylinder is larger than that of the anchoring sub-cylinder, and the anchoring sub-cylinder can be inserted into the anchoring mother cylinder and rotate freely; the length of the anchoring sub-cylinder is larger than that of the anchoring mother cylinder. After the anchoring sub-cylinder is inserted into the anchoring mother cylinder, a limiting ring is set at the exposed root part, and it is fixed in the anchoring mother cylinder with an L-shaped gasket and a hexagonal bolt, which does not restrict the free rotation of the anchoring sub-cylinder.

[0011] As a preferred embodiment, the length of the embedded sleeve is greater than the outer diameter of the sub-tube body, and it is obliquely inserted into the center of the exposed part of the sub-tube body through the reserved hole. Both ends are welded around, the lower end is milled smoothly, and the upper end is exposed to a certain length. The installation direction of the embedded sleeve takes the transverse inclination angle of all decorative inclined cables (such as Figure 8 The average value is shown).

[0012] Preferably, after the decorative cable passes through the embedded sleeve, it is anchored with an arc-shaped anchor plate. One side of the arc-shaped anchor plate is an arc surface with an arc diameter equal to the outer diameter of the sub-tube body, and the other side is a wedge-shaped plane to accommodate the uniform installation angle of the decorative cable in the transverse direction of the bridge.

[0013] Beneficial effects of the present invention:

[0014] In the present invention, the anchoring sub-tube can rotate freely around the anchoring mother tube, which meets the need of installing the decorative inclined cable at any angle along the bridge direction and unifies the geometric dimensions of the anchoring block.

[0015] The embedded casing is installed at a uniform angle in the horizontal direction of the decorative cable bridge (such as Figure 8 It is pre-buried obliquely on the anchor sub-tube, which can adapt to the angle change of the decorative cable-stayed bridge in a certain range, and unifies the geometry and positioning dimensions of the pre-buried sleeve and the arc-shaped anchor pad.

[0016] The present invention adopts a unified anchoring device, which is adaptable to any installation angle of the decorative cable along the bridge and a certain range of angle changes in the transverse direction of the bridge. It has the advantages of unified model, convenient processing, reduced on-site high-altitude operation and positioning difficulty, and greatly improved construction accuracy and installation efficiency.

[0031] 1. Mother barrel

[0032] like Figure 2 , Figure 3 As shown, the anchoring mother tube 1 comprises: a mother tube body 101, a mother tube bottom sealing plate 102, cylindrical head welding nails 103, a stiffening ring 104, a stiffening rib 105, and an embedded bolt sleeve 106, wherein a plurality of bolt holes 107 are circumferentially arranged on the stiffening ring 104.

[0033] The mother cylinder body 101 is a circular steel cylinder, the mother cylinder bottom sealing plate 102 is a circular steel plate, and the stiffening ring 104 is a circular steel plate.

[0034] The bottom of the mother tube body 101 is welded and sealed with a mother tube bottom sealing plate 102, and a stiffening ring 104 is welded at the end to strengthen the end; a plurality of cylindrical head welding nails 103 are circumferentially welded on the outer wall of the mother tube body 101, and the cylindrical head welding nails 103 enhance the bonding effect between the anchor mother tube 1 and the main beam or guardrail concrete.

[0035] The stiffening ribs 105 are welded to the mother barrel body 101 and the stiffening ring 104 to increase the connection strength and stability between the mother barrel body 101 and the stiffening ring 104 .

[0036] The reinforcing ring 104 is circumferentially provided with bolt holes 107 , which are spaced apart from the reinforcing ribs 105 , the embedded bolt sleeves 106 are aligned with the centers of the bolt holes 107 , and the embedded bolt sleeves 106 are welded around the reinforcing ring 104 .

[0037] Apply lubricating oil to the inner wall of the anchoring mother tube 1.

[0038] 2. Sub-tube

[0039] like Figure 4 , Figure 5 As shown, the anchoring sub-tube 2 comprises: a sub-tube body 201 , a sub-tube inner sealing plate 202 , a limiting ring 203 , a sub-tube end sealing plate 204 , an embedded sleeve 205 , and an arc-shaped anchor pad 206 .

[0040] The sub-cylinder body 201 is a circular steel cylinder, the sub-cylinder inner sealing plate 202 and the sub-cylinder end sealing plate 204 are circular steel plates, and the limiting ring 203 is a circular steel plate.

[0041] The diameter of the sub-tube inner sealing plate 202 is slightly smaller than the inner diameter of the sub-tube body 201, and 202 is embedded in and welded around the left end of 201.

[0042] The diameter of the sub-tube end sealing plate 204 is larger than the outer diameter of the sub-tube body 201 and is welded around the right end of 201.

[0043] The left end of the anchor sub-tube 2 is inserted into the anchor mother tube 1, and a limiting ring 203 is provided at the exposed root to prevent the anchor sub-tube 2 from being pulled out during use. The limiting ring 203 is welded on the sub-tube body 201.

[0044] like Figures 1 to 4 As shown, the L-shaped gasket 3 presses the limit ring 203, and the hexagonal bolt 4 is bolted into the bolt hole 107 to fix the anchor sub-tube 2 on the anchor mother tube 1, and ensure that the anchor sub-tube 2 can rotate freely to adapt to any installation angle of the decorative inclined cable 5 along the bridge direction.

[0045] If the anchor sub-tube 2 needs to be replaced during the operation of the bridge, the hexagonal bolt 4 can be unscrewed for replacement.

[0046] like Figure 8 As shown, the transverse installation angle of the decorative inclined cable 5 is relatively uniform, the change is generally not large, and the cable force is relatively small. In order to facilitate processing, a uniform transverse installation angle is adopted (the average transverse inclination angle of all decorative inclined cables 5 is taken).

[0047] like Figure 4 , 5 As shown, the embedded casing 205 is a round steel pipe. Figure 8 The uniform transverse bridge installation angle shown is obliquely inserted and pre-buried in the exposed central part of the anchor sub-tube 2.
