Description

Technical Field

[0001] The utility model belongs to the technical field of the horizontal saddle of the rotary cable suspension bridge, and particularly relates to a socket type partition structure of the horizontal saddle. Background Art

[0002] The horizontal saddle of the rotary cable suspension bridge includes a main saddle and a rotary saddle, which have the same function as the main saddle installed on the tower of a conventional suspension bridge, and are both permanent structural members for supporting the rotary main cable. The notch of the traditional saddle is upward or inclined upward during installation, and the saddle partition is a serrated structure. When installing, it is directly embedded. There are two installation methods at the joints of different layers of partitions: (1) The upper and lower layers of partitions are in direct contact without any connection treatment, and are fixed by squeezing with the cable strands on both sides; the disadvantage is that it is easy to twist when the cable strands on both sides are asynchronous or the bulging forces of the cable strands are unequal. (2) The groove of the assembled partition is bevelled (the bevelled length is 50 mm, the bevelled angle is 45°, and the depth is 4 mm), and the socket partitions are connected by welding (after welding, it needs to be polished and then cold-sprayed with zinc coating for anti-corrosion treatment). This connection method increases the bearing capacity of the partition; the disadvantage is that the cable strand wires need to be protected during welding, which is easy to accidentally injure the wires, and the operation in a limited space is difficult. However, for the horizontal saddle, the extension direction of the partition changes from vertical to horizontal. Compared with the conventional vertical saddle, the horizontal partition is more likely to be skewed so that the upper and lower positions of adjacent partitions are misaligned.

[0003] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies of the prior art. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a socket type partition structure of the horizontal saddle.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A socket type partition structure of the horizontal saddle is formed by splicing a plurality of layer partitions in the horizontal direction. The splicing structure between two adjacent layer partitions includes a first splicing board on one side layer partition and a second splicing board on the other side layer partition. The thicknesses of the first splicing board and the second splicing board are less than the thickness of the layer partition, and the splicing surface is a horizontal plane; after the first splicing board and the second splicing board are spliced, they are fixed by fasteners penetrating through both of them along the thickness direction, and the exposed surfaces of the first splicing board, the second splicing board and both ends of the fasteners do not exceed the surface of the layer partition.

[0007] Further, the splicing surface of the first splicing board and the second splicing board is a horizontal plane.

[0008] Further, the lengths of the first splicing board and the second splicing board are more than 18 mm.

[0009] Further, reserved holes for threaded connection with the fasteners are provided on the first and second splicing plates, and a counterbore is provided at the exposed end of the reserved hole.

[0010] In one embodiment, in a splicing structure, the number of the first and second splicing plates is one each; the first and second splicing plates have the same length; the exposed surfaces of the first and second splicing plates are flush with one side surface of the layer partition board.

[0011] On the basis of the above embodiment, the thickness of the layer partition board is A, and the thickness of the first and second splicing plates is 0.5A.

[0012] On the basis of the above embodiment, the thickness of the layer partition board is 10 mm, and the thickness of the first and second splicing plates is 4.8 - 5.0 mm.

[0013] In another embodiment, in a splicing structure, there are two first splicing plates arranged in parallel, and the number of the second splicing plates is one; a socket is formed between the two first splicing plates, and the second splicing plate serves as an insertion plate and is inserted and matched with the socket; the depth of the socket is 0.2 - 0.5 mm greater than the length of the insertion plate.

[0014] On the basis of the above embodiment, if the thickness of the layer partition board is B, the thickness of the socket is 0.5B, and the thickness of the insertion plate is 0.4B.

[0015] On the basis of the above embodiment, the thickness of the layer partition board is 10 mm, the thickness of the socket is 5 mm, and the thickness of the insertion plate is 4 mm.

[0016] The beneficial effects of the present utility model are as follows:

[0017] Through the specially designed splicing structure of the present utility model, after the first and second splicing plates are spliced, they are fixed by fasteners, so that the layer partition boards are firmly fixed and will not be skewed or displaced without the extrusion of the side wire strands on both sides; moreover, after installation, the fasteners, the first and second splicing plates do not protrude beyond the surface of the partition board and do not affect the installation of the wire strands of the wire strands; the structure of the present utility model can solve the problem of increasing the bearing capacity of the partition connection, and at the same time, there is no need for welding during installation, the installation time is faster, the construction is safer, and at the same time, the risk of damage to the wire strands caused by the welding of the partition board in the traditional method is avoided.

Detailed implementation manners

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0027] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0028] As Figures 1 to 6 shown, a horizontally cable saddle socket-type partition structure is formed by splicing a plurality of layer partition boards in the horizontal direction. The splicing structure between two adjacent layer partition boards includes a first splicing board 51 on one side layer partition board and a second splicing board 52 on the other side layer partition board. The thickness of the first splicing board 51 and the second splicing board 52 is less than the thickness of the layer partition board, and the splicing surface is a horizontal plane; after the first splicing board 51 and the second splicing board 52 are spliced, they are fixed by fasteners penetrating through both in the thickness direction, and the exposed surfaces of the first splicing board 51, the second splicing board 52 and both ends of the fasteners do not exceed the surface of the layer partition board.

[0029] Furthermore, the splicing surface of the first splicing board 51 and the second splicing board 52 is a horizontal plane, and the horizontal splicing surface is easy to control the processing.

[0030] Further, the lengths of the first splicing board 51 and the second splicing board 52 are more than 18 mm, and the thickness ranges from 2 mm to 0.5 times the thickness of the partition board.

[0031] Further, reserved holes for threaded connection with the fasteners are provided on the first splicing board 51 and the second splicing board 52. A counterbore 43 is provided at the exposed end of the reserved hole. The depth of the counterbore 43 is slightly greater than the height of the bolt head and the height of the nut for connecting the first splicing board 51 and the second splicing board 52. Generally, bolts or flat head set screws are used as fasteners, which can be used in conjunction with nuts. After installation, the fasteners do not protrude from the surface of the partition board and will not affect the installation of the strand wires.

[0032] The layer partition board of the present utility model is fixedly penetrated by the locking member after being spliced by the first splicing board 51 and the second splicing board 52, which ensures the bearing capacity of the partition board connection. At the same time, it can ensure that the partition board can still maintain its own structure without separation when there is no external force (strand wires on both sides) support. And the use of fasteners such as screws and set screws facilitates the rapid installation on site using an electric hand drill. Compared with the traditional method of welding and fixing between partition boards, the on-site construction of the present utility model is faster, and at the same time, the damage to the strand wires caused by welding can be avoided.

[0033] As Figure 1 shown, one partition board is made of three layer partition boards arranged in sequence from the inside to the outside, namely the first layer partition board 1, the second layer partition board 2, and the third layer partition board 3. Then there is a splicing structure between the first layer partition board 1 and the second layer partition board 2, and there is a splicing structure between the second layer partition board 2 and the third layer partition board.

[0034] The following gives two specific embodiments.

[0035] Embodiment 1

[0036] As Figure 2 、 Figure 3 shown, in a splicing structure, the numbers of the first splicing board 51 and the second splicing board 52 are both one. Specifically, the first splicing board 51 is provided on the first layer partition board 1, and the second splicing board 52 and the first splicing board 51 for cooperating with the first layer partition board 1 are respectively provided on both sides of the second layer partition board 2. The second splicing board 52 for cooperating with the first splicing board 51 on the second layer partition board 2 is provided on the third layer partition board 3. The first splicing board 51 and the second splicing board have the same length for easy cooperation. The exposed surfaces of the first splicing board 51 and the second splicing board 52 are flush with the surface of one side of the layer partition board. [[ID=2,6]]

[0037] Further, as Figure 3 shown, the position of the first splicing board 51 can be below the second splicing board 52, or the position of the second splicing board 52 can be below the first splicing board 51. Preferably, the position of the first splicing board 51 installed first is below, so that it can support the edge of the next layer partition board and is more convenient for installation.

[0038] Further, the thickness of the layer partition is A, and the thicknesses of the first splicing board 51 and the second splicing board 52 are 0.5A. When the first splicing board 51 and the second splicing board 52 are installed, the total thickness is the same as that of the layer partition. Specifically, the thickness of the layer partition is 10 mm, and the thicknesses of the first splicing board 51 and the second splicing board 52 are both 4.5 - 5.0 mm. Preferably, the thicknesses of the first splicing board 51 and the second splicing board 52 are both 4.9 mm.

[0039] In this embodiment, threaded holes for threaded connection with the fasteners are provided on the first splicing board 51 and the second splicing board 52.

[0040] In this embodiment, the first splicing board 51, the second splicing board 52 and the layer partition are of an integral structure. That is, after the layer partition body is processed, the top surface of the cantilever end plate of the first layer partition 1 is cut by a numerical control machine tool to form the first splicing board 51, and then the bottom surface of one end plate and the top surface of the other end plate of the second layer partition 2 are cut by a numerical control machine tool to form the second splicing board 52 and the first splicing board 51 respectively. Then, the bottom surface of the cantilever end plate of the third layer partition 3 close to the second layer partition 2 is cut by a numerical control machine tool to form the second splicing board 52. Then, the first layer partition 1, the second layer partition 2 and the third layer partition 3 are respectively assembled together. After ensuring that there is no step at the joint and the joint is tight, the first splicing board 51 and the second splicing board 52 are grooved and drilled with threaded holes (the first reserved hole 41 and the second reserved hole 42). The first reserved hole 41 and the second reserved hole 42 are set as threaded holes with a counterbore 43. The depth of the counterbore 43 is slightly greater than the height of the bolt head and the height of the nut. The bolt uses an internal hexagon bolt. After the bolt is tightened, the bolt head and the nut are both lower than the surface of the splicing board. For example, a nut can be embedded in the counterbore 43 of the first reserved hole 41, and then the first splicing board 51 and the second splicing board 52 are connected by installing a bolt in the second reserved hole 42. After the three-layer splicing board is trial-assembled and meets the requirements, number marks and installation manuals are made for the splicing board, and then the three-layer splicing board is disassembled and packed and stacked.

The receiving slot 11 and the receiving plug board 21 are both centered. With this form of splicing structure, when installing, there is no need to consider the front and back of the layer partition, and the receiving plug board 21 is inserted into the receiving slot 11. The two sides of the receiving plug board 21 are supported by the first splicing boards 51 and are not easy to be skewed;

[0043] Further, if the thickness of the layer partition board is B, the thickness of the socket 11 is 0.5B, and the thickness of the inserting plate 21 is 0.4B. Specifically, as Figure 5 , Figure 6 shown ( Figure 6 the numerical unit in is millimeter), the thickness of the layer partition board is 10 mm; the depth of the socket 11 is 20.5 mm and the thickness is 5 mm; the length of the inserting plate 21 is 20 mm and the thickness is 4 mm, and a chamfer is provided at the end of the inserting plate 21.

[0044] In this embodiment, threaded holes are provided on the two first splicing plates 51 that form the socket 11, and it is preferable that the reserved holes corresponding to the fasteners provided on the second splicing plate 52 are clearance holes.

[0045] In this embodiment, the first splicing plate 51, the second splicing plate 52 and the layer partition board are of an integral structure. That is, after the main body of the layer partition board is processed, the cantilever end of the first layer partition board 1 is grooved by a numerical control machine tool to form the first splicing plate 51, and then the top surface and the bottom surface of one end plate of the second layer partition board 2 are respectively cut by a numerical control machine tool to form the second splicing plate 52. The other end of the second layer partition board 2 is grooved by a numerical control machine tool to form a splicing plate, and then the top surface and the bottom surface of the cantilever end plate of the third layer partition board 3 close to the second layer partition board 2 are respectively cut by a numerical control machine tool to form the third splicing plate. Then, the first, second, and third layer partition boards are respectively assembled together. After ensuring that there is no step at the joint and the joint is tight, the first splicing plate 51 and the second splicing plate 52, and the second splicing plate 52 and the third assembly are grooved and drilled (the first reserved hole 41 and the second reserved hole 42 are opened). A counterbore 43 is provided at the outer end of the first reserved hole 41, and a threaded hole with a nut is fixed in the counterbore 43. The nut is of an internal hexagonal structure; the second reserved hole 42 is provided as a reserved clearance hole; the depth of the counterbore 43 is slightly greater than the height of the bolt head and the height of the nut. After the bolt is tightened, both the bolt and the nut are lower than the surface of the splicing plate. After the trial assembly of the three-layer splicing plate meets the requirements, number markings and installation manuals are made for the splicing plate, and then the three-layer splicing plate is disassembled and packed and stacked.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
