In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The implementation of the present invention will be described in detail with reference to the preferred embodiments.
Referring to fig. 1, a cable dome cable space multidirectional intersection 100 for a space cable structure according to a preferred embodiment of the present invention includes an upper cover plate 1, a lower cover plate 2, an intermediate partition plate 3, a central steel pipe 4 and a cable lug plate, and the specific structure of each component and its location and connection relationship are described in detail below with reference to specific diagrams.
In some embodiments, as shown in fig. 1, the upper cover plate 1, the lower cover plate 2 and the middle partition plate 3 are horizontally placed and respectively connected and fixed at the upper end, the lower end and the middle position of the central steel pipe 4, and the middle partition plate 3 divides the node into an upper half area and a lower half area, wherein the upper half area and the lower half area respectively bear different functions, and the functions will be described in detail later. It should be understood that the intermediate partition plate 3 is fixedly connected to the central position of the central steel pipe 4, and should not be limited to the central position of the central steel pipe 4, but may be a proper position between the upper cover plate 1 and the lower cover plate 2, and is preferably a central position according to the calculation of stress.
The upper cover plate 1, the lower cover plate 2, the middle partition plate 3 and the central steel pipe 4 are integrally in a king-shaped structure on the side surface, the whole shape of the node is attractive, the structural modeling is simple, the processing and the manufacturing are easy, and the installation is easy on site. Considering the connection strength of the whole node, the upper cover plate 1, the lower cover plate 2 and the middle partition plate 3 are made of steel plates, and preferably circular steel plates are adopted, as shown in fig. 2.
In some embodiments, referring to fig. 1 and 2, the cable lug plate includes at least a first cable lug plate 5 and a second cable lug plate 6, the first cable lug plate 5 is vertically disposed in the upper half, the second cable lug plate 6 is vertically disposed in the lower half, and the cable axis extension lines of the first cable lug plate 5 and the second cable lug plate 6 are connected meet at the center O of the node. According to the design trend of the inhaul cable, the inhaul cable lug plates at corresponding positions and angles are matched, so that all directions of stress of all directions of inhaul cables at the joints are converged at the center of the joints, the stress balance is kept, and the joint stress is more reasonable.
In some embodiments, referring to fig. 2 and 3, the upper and lower edges of the first guy lugs 5 are welded to the upper cover plate 1 and the middle partition plate 3, the vertical edges are welded to the central steel pipe 4, and the upper and lower edges of the second guy lugs 6 are welded to the middle partition plate 3 and the lower cover plate 2, and the vertical edges are connected to the central steel pipe 4. Through three-sided welded fastening with cable ear plate and upper and lower apron, intermediate baffle and central steel pipe, cable pulling force leans on intermediate baffle and central steel pipe to the cable slant sets up intermediate baffle and plays main atress effect under the state, and the node atress is more reasonable.
In some embodiments, referring again to fig. 1, the first tab 5 is configured to connect a cable oriented obliquely upward, i.e., with the cable axis oriented in an obliquely upward direction, at an obtuse angle, such as angle α in the figure, with the axis of the central steel tube 4 in a vertically downward direction, and the second tab 6 is configured to connect a cable oriented obliquely downward, i.e., with the cable axis oriented in an obliquely downward direction, at an acute angle, such as angle β in the figure, with the axis of the central steel tube 4 in a vertically downward direction. The cable ear plate of the upper half area is connected with the cable which is obliquely upwards, the cable ear plate of the lower half area is connected with the cable which is obliquely downwards, the node cable layout is more reasonable, and the extension line of each cable axis can be ensured to meet at the center O of the node.
In some embodiments, the first cable lug plate 5 may be provided with one or more pieces, the position and angle being determined according to the axial direction of the connected cable. Also, the second stay tab plate 6 may be provided with one or more pieces, the position and angle being determined according to the axial direction of the connected stay. As shown in fig. 3, two first cable lug plates 5 and two second cable lug plates 6 are provided, which is particularly important when there are more converging cables, and since the cable dome structure node mainly serves to connect cables in different directions, the node structure is relatively complex when there are more converging cables, and cast steel nodes are generally adopted in the conventional structural design. The cast steel node is greatly higher in cost than the steel plate splicing node due to the need of a manufacturing die and a more complex processing technology. Especially when the cable dome structure is not centrosymmetric, the included angles among the cables at all positions are different, so that each node is required to be independently manufactured with a die, the manufacturing cost of the node is further improved, and the manufacturing period is prolonged. According to the invention, the multi-pull-cable lug plates are arranged in the upper and lower different areas, so that the multi-pull-cable junction connection requirements of multi-directional pull cables with different directions, different angles and different purposes are met.
In some embodiments, the central steel pipe 4 is not an entire steel pipe, but adopts a segmented structure, and comprises a first pipe section 4-1 and a second pipe section 4-2, wherein the first pipe section 4-1 is positioned in an upper half area, the second pipe section 4-2 is positioned in a lower half area, the upper end and the lower end of the first pipe section 4-1 are respectively welded and fixed with the centers of the upper cover plate 1 and the middle baffle plate 3, and the upper end and the lower end of the second pipe section 4-2 are respectively welded and fixed with the centers of the middle baffle plate 3 and the lower cover plate 2. Through adopting sectional type steel pipe structure, be convenient for steel pipe tip and upper and lower apron and intermediate baffle welded connection, and avoided trompil at intermediate baffle 3 center and increased the processing complexity of baffle, and the steel pipe perforation is more complicated than the segmentation direct weld.
In some embodiments, the present invention may further provide a third cable lug plate 7, where the third cable lug plate 7 is provided in the upper half or the lower half, and when the third cable lug plate 7 is provided, the first cable lug plate 5 and the second cable lug plate 6 are used to connect cable dome chordae, and the third cable lug plate 7 is used to connect cable dome chordae. Since the cable force of the spinal cord is far greater than that of the inclined cord in general, the thickness of the steel plates required by the first cable lug plate 5 and the second cable lug plate 6 is also far greater than that of the third cable lug plate 7, if the third cable lug plate 7, the first cable lug plate 5 and the second cable lug plate 6 adopt the same steel plate, the third cable lug plate 7 can cause larger material waste. It should be noted that the position and thickness of the third tab plate 7 are determined according to the stress calculation, and when the third tab plate is disposed in the upper half area, the third tab plate and at least one of the second tab plates may be in the same vertical plane or not, and the thicknesses of the third tab plate and the second tab plates may be the same or different; also, when disposed in the lower half region, the third tab plate and at least one of the first tab plates may or may not be in the same vertical plane, and may or may not be the same thickness. The above-mentioned third tab 7 may be made of a steel plate with a smaller thickness, and it should be understood that each tab is separately provided and may be cut separately, and in general, the thickness of the third tab 7 is smaller to save materials, which does not mean that the thickness of the third tab 7 must be smaller than the thickness of the first tab 5 and the second tab 6 connected to the spinal cord. In particular, when the third cable lug plate and one first cable lug plate or one second cable lug plate can be positioned in the same vertical plane, the upper cable lug plate and the lower cable lug plate are separated by virtue of the middle partition plate 3, the upper cable lug plate and the lower cable lug plate are not in a whole plate structure, but are independently designed in a partition manner, and are independently cut, and the respective thicknesses are determined according to respective stress calculation, so that the stress requirements are met, and the mutual influence is avoided.
In some embodiments, referring to fig. 4 and 5, the present invention further provides a stiffening rib 8, where the stiffening rib 8 is disposed at a position corresponding to at least one second lasso plate 6 in the upper half area, and the upper and lower edges thereof are welded and fixed with the upper cover plate 1 and the middle partition plate 3, and the vertical edges thereof are welded and fixed with the central steel pipe 4. Of course, the stiffening rib plate 8 can also be arranged at the position of the lower half area corresponding to at least one first guy lug plate 5, the upper and lower edges of the stiffening rib plate are welded and fixed with the middle partition plate 3 and the lower cover plate 2, and the vertical edges of the stiffening rib plate are welded and fixed with the central steel pipe 4. The stiffening rib plates are additionally arranged at the positions where the first cable lug plates 5 or the second cable lug plates 6 are arranged, and are coplanar with the corresponding first cable lug plates 5 or the second cable lug plates 6 in the vertical plane, so that the integral strength of the middle partition plate 3 is improved, and the strength and stability of the joints are enhanced.
It is easy to understand that when the third stay plates 7 and the stiffening rib plates 8 are provided at the same time, the stiffening rib plates 8 should avoid the positions of the third stay plates 7, at the positions where the third stay plates 7 are not provided in the upper or lower half.
In some embodiments, the joint of the present invention further comprises a stay lug plate 9 vertically connected and fixed to the bottom of the lower cover plate 2 for connecting the stay, and the stay lug plate shape is determined according to the axial direction of the connected stay.
The upper cover plate 1, the lower cover plate 2, the middle partition plate 3, the stay lug plate and the stay lug plate 9 are formed by cutting steel plates, and the central round tube 4 is a seamless steel tube. The size of the upper cover plate, the lower cover plate and the middle spacer plate is determined by stress calculation, and the length of a welding seam between the cable lug plate and the middle cover plate is ensured to be larger than the length of the welding seam calculated according to the cable force of the inhaul cable.
Through the explanation, the node structure provided by the invention is easy to foresee, simple to manufacture, reasonable in stress, high in strength and low in material consumption, and particularly, the number of the inhaul cables is flexible and the arrangement is flexible for the condition of connecting the space with multiple inhaul cables, so that the node structure is suitable for various structural forms such as large-span space buildings, bridges and the like, and is wide in application and worthy of popularization.
It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
