Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and in particular relates to a shape-preserving reinforcement unit of an anchor platform segmented large opening structure. Background Art

[0002] Based on a single-segment pre-installation method for the entire anchor platform, the bow segment is divided into upper and lower layers in the ship segmentation. In order to ensure the integrity of the anchor platform, the anchor platform part is made into a separate assembly and is divided into the upper segment. Therefore, the insertion area of ​​the lower segment anchor platform is a large opening structure 1, which is trumpet-shaped, larger at the top and smaller at the bottom, and a triangular opening is left in the connected platform plate structure, such as Figure 1 shown.

[0003] In order to ensure the accuracy and strength of the large opening structure 1 and avoid deformation during the storage, transportation and lifting of the sections, a large number of connecting supports 12 are usually added to the platform plate 8 and the outer plate 6 of the large opening structure 1 as a shape-preserving and strengthening structure connecting the two ends of the opening, and are removed after the sections are turned over and assembled. Figure 2 shown.

[0004] Based on the above situation, the method of using connecting supports as shape-retaining reinforcement for the anchor platform segmented large opening structure mainly has the following problems: (1) The installation and removal of the shape-retaining reinforcement of the large opening structure are single-piece operations, with many construction steps and low production efficiency. (2) The length of the shape-retaining reinforcement of the large opening structure is usually more than 2m and the weight is heavy. It is difficult for construction workers to carry it during the installation and removal of the reinforcement, and a crane is generally used to assist in lifting. In addition, due to the large number of reinforcements and single-piece operations, the crane occupancy rate is high. (3) The shape-retaining reinforcement construction in the middle of the large opening structure requires additional scaffolding, which increases the construction cost. Utility Model Content

The connecting device includes a connecting reinforcement and a protective flat iron. One end of the connecting reinforcement is fixedly connected to the platform plate or the outer plate, and the other end of the connecting reinforcement is fixedly connected to the protective flat iron. The protective flat iron is connected to the main beam and the column auxiliary beam.

[0011] Furthermore, the triangular frame is formed by connecting the first main beam, the second main beam and the third main beam end to end, and the first reinforcing auxiliary beam and the second reinforcing auxiliary beam are provided on the inner side of the triangular frame, the two ends of the first reinforcing auxiliary beam are respectively connected to the first main beam and the second main beam, one end of the second reinforcing auxiliary beam is vertically connected to the intersection of the first reinforcing auxiliary beam and the second main beam, and the other end of the second reinforcing auxiliary beam is connected to the third main beam.

[0012] Furthermore, the lifting ears are arranged on two main beams on the triangular frame except the main beam between two outer plates of the segmented large opening structure of the anchor platform.

[0013] Furthermore, there are three triangular frames.

[0014] Furthermore, a forklift tube for connecting to a fork of a forklift is provided on the triangular frame located in the middle layer.

Adjacent triangular frames 2 are connected by multiple column auxiliary beams 3 to form a triangular column type stable unit frame.

[0033] The triangular frame 2 is formed by connecting three main beams 14 end to end, and a reinforcing auxiliary beam is provided on the inner side of the triangular frame. In this embodiment, the triangular frame 2 is formed by connecting the first main beam 21, the second main beam 22 and the third main beam 23 end to end, and a first reinforcing auxiliary beam 31 and a second reinforcing auxiliary beam 32 are provided on the inner side of the triangular frame, and the two ends of the first reinforcing auxiliary beam 31 are respectively connected to the first main beam 21 and the second main beam 22, one end of the second reinforcing auxiliary beam 32 is vertically connected to the intersection of the first reinforcing auxiliary beam 31 and the second main beam 22, and the other end of the second reinforcing auxiliary beam 32 is connected to the third main beam 23.

[0034] In this embodiment, six column auxiliary beams 3 are arranged between adjacent triangular frames 2, and the adjacent triangular frames 2 are connected at their respective opposite vertices 4 and respective opposite main beams 14 through the column auxiliary beams 3. The connection position between the column auxiliary beam 3 and the main beam 14 is close to the midpoint of the main beam 14. The specific connection operation between the triangular frames 2 is as follows: first, based on a triangular frame, six column auxiliary beams are arranged at each vertex of the triangular frame and close to the midpoint of each main beam; then, a second triangular frame is superimposed and connected, and six column auxiliary beams are arranged at each vertex of the second triangular frame and close to the midpoint of each main beam; finally, a third triangular frame is superimposed and connected to form a three-layer triangular column type stable unit frame.

[0035] After checking the weight and center of gravity of the shape-retaining reinforcement unit, a plurality of lifting ears 5 for lifting are fixed on the outer edges of the main beams 14 of the topmost and bottommost triangular frames 2. In this embodiment, the two main beams 14 on the triangular frame 2 provided with the lifting ears 5 are the first main beam 21 and the third main beam 23, the first main beam 21 and the third main beam 23 are not between the two outer plates 6 of the segmented large opening structure of the anchor platform, and two lifting ears 5 are provided at appropriate positions on each main beam 14.

[0036] A support foot 7 is fixedly provided on each of the three vertices 4 of the triangular frame 2 at the top layer. When the shape-retaining reinforcement unit is dismantled at the assembly site, the shape-retaining reinforcement unit is supported by the support foot 7 .

[0037] In this embodiment, in order to transport the shape-retaining reinforcement unit by forklift instead of crane after removal, and reduce the number of crane coordination times, a forklift tube 13 for connecting with the fork of a forklift is provided on the triangular frame 2 located in the middle layer. According to the model of the fork, the forklift tube 13 is appropriately provided on the reinforcement auxiliary beam and / or the main beam.

[0038] The triangular frame 2 at the bottom layer is connected to the platform plate 8 of the anchor platform segmented large opening structure 1 through multiple adjustable connecting devices, and the other triangular frames are connected to the outer plate 6 of the anchor platform segmented large opening structure 1 through multiple adjustable connecting devices. The connecting device includes a connecting reinforcement 9 and a protective flat iron 10. One end of the connecting reinforcement 9 is fixedly connected to the platform plate non-structural surface 11 or the outer plate frame, and the other end of the connecting reinforcement 9 is fixedly connected to the protective flat iron 10. The protective flat iron 10 is welded to the main beam and column auxiliary beam of the triangular frame 2. The protective flat iron 10 should cover the main beam and column auxiliary beam of the triangular frame 2 connected thereto.

[0039] like Figure 4 As shown, the anchor platform is constructed in sections and the connecting device is installed on the platform plate 8 in the large opening area in advance, that is, the connecting reinforcement 9 is installed on the non-structural surface 11 of the platform plate, and a protective flat iron 10 is added to the free end of the connecting reinforcement 9. Figure 5 As shown, the shape-retaining reinforcement unit is hoisted to the connection device of the platform plate 8 by a crane, and the sealing node of the shape-retaining reinforcement unit is as shown in FIG. Figure 6 After the connection device on the shape-retaining reinforcement unit and the platform plate 8 is sealed, the crane is unhooked. The construction personnel use the painting scaffolding at the edge of the opening to install the connection device on the outer plate 6 on both sides of the opening. The connection reinforcement 9 is welded and fixed to the docking position of the main beam 14 and the column auxiliary beam 3 through the protective flat iron 10. The sealing node is referred to Figure 7 and Figure 8 The protective flat iron 10 covers the main beam 14 and the column auxiliary beam 3 connected thereto. Finally, the schematic diagram of the shape-preserving reinforcement unit of the anchor platform segmented large opening structure 1 after installation is as follows: Fig. 9 After the shape-retaining reinforcement unit is installed, the structural spacing between the shape-retaining reinforcement unit and the platform plate 8 and the outer plate 6 is 100 mm, and the length of the connecting reinforcement 9 is generally less than 0.5 m. The remaining materials can be used for construction, which improves the expected utilization rate and is convenient for construction workers to carry.

[0040] like Fig.10 As shown, when the anchor platform segment is turned over at the assembly site and the shape-retaining reinforcement unit is removed, the crane hangs the lifting lug 5 in advance to ensure that the wire rope is stressed, and then the connecting reinforcement members 9 are cut off from the lower mouth of the anchor platform segment upward in sequence, and the shape-retaining reinforcement unit is hoisted down as a whole. The protective flat iron 10 on the main beam 14 is retained for subsequent use and positioning of the connecting reinforcement member 9.

[0041] The utility model is installed and removed as a whole by a crane. The crane is equipped with two hooks, which greatly reduces the occupancy rate of the crane and significantly improves production efficiency. In addition, construction personnel can use the pre-erected scaffolding for painting in the large opening structure area of ​​the anchor platform to construct the device, avoiding the need to set up additional scaffolding and reducing construction costs. When the shape-retaining reinforcement unit is removed, the connecting reinforcement is cut from bottom to top, and finally the construction personnel stand on the platform board to cut the connecting reinforcement located on the platform board. The construction position is safe, eliminating the risk of injury during the construction process.
