1 is a reference diagram for explaining a conventional lattice object and the arrangement state thereof.

As shown in Fig. 1, a conventional lattice lumber was used by placing wood lumber on a concrete block and placing plastic lumber on it. In addition, conventionally, due to the heavier weight, antagonism is concentrated on the bow and stern, and the light weight center of the hull is less disposed.

Since the conventional lattice bancture supports the hull with banjo placed on the concrete block, it supports the hull in the form of a dot, and thus lattice banjo should be disposed at the intersection of the hull frame to prevent damage to the hull.

Therefore, if a change is made in the linear or adenoma, it is necessary to relocate the antagonists placed in the dock. There is also a limit to the need for drainage and drainage in the dock for the relocation of antagonism.

2 to 4 are reference diagrams for explaining an example of the lattice object according to the disclosed technology.

2 to 4, the grating banjo may be configured by obtaining a metal frame 120 on four concrete blocks 110. Here, the metal frame 120 may be configured as iron having a strength that can sufficiently withstand the load by the hull, and in order to support the load stably H-beam, or the I-type, built-up (such as the example shown) Built-up) may be formed.

A plurality of plastic semi-wooden board 130 is located on the metal frame may be in direct contact with the wiring body. Here, the plastic half board 130 may be formed of a plastic half board having a strength and a predetermined elasticity to withstand a sufficient load. 2 to 4, but provided with a plurality of plastic boards 130 on a metal frame, it is clear that can be replaced with wood boards, etc. according to the embodiment.

The example shown in FIG. 2 shows a lattice antagonist that can support the hull center portion, while the example shown in FIG. 4 shows a lattice antler that can support the bow or stern.

That is, in the case of the lattice block supporting the bow and stern shown in Figure 2, the weight to be supported is high, it can be assembled by narrowing the interval of the grid as shown in the example shown. On the other hand, the grating block supporting the center portion of the hull is relatively low weight to support it can be assembled by widening the interval of the grating.

Since the size of the lattice can be adjusted in this way, the amount of metal frame lattice can be minimized and the stress applied to the metal frame can be reduced.

3 is a reference diagram illustrating an example of coupling the concrete block 110 to the metal frame 120.

As shown in FIG. 3, the metal frame 120 is connected between the concrete block and the block, and thus, unlike the conventional art, the hull may be supported in the form of a lattice. Since this simple assembly is possible, as shown in FIG. 2 or 4, it is possible to easily assemble blocks having different sizes of grids. In addition, it can be seen that the assembly is relatively simple, so that the installation of the lattice lumber is very easy, and the structure is able to withstand a sufficient load even for simple assembly.

In addition, as shown in Figure 3, when coupling the metal frame 120 on the concrete block 110 may be coupled by placing at least one washer therebetween. Here, the washer can be used for height adjustment in addition to the buffer role. In more detail, the dock bottom generally has a predetermined slope for drainage, and the grid can also have a slope in accordance with this slope. That is, inclinations in the length and width directions between the metal frames 120 may occur according to the position of the concrete block 110. The disclosed technique adjusts the number of washers between the concrete block 110 and the metal frame 120 to correct this inclination so that the angle between the hull blocks to be leveled (loaded) or loaded between the metal frames 120 is adjusted. It can be adjusted to suit.

5 is a reference diagram illustrating a layout of a lattice ban in accordance with an example of the disclosed technology. As shown in FIG. 5, the grating lumber according to the disclosed technique may support the hull in the form of a grating through the metal frame 120. In other words, the grid grate according to the disclosed technology supports the hull in the form of a grid, not in the form of points, so that damage to the hull does not occur even when the portion of the hull frame is not supported.

Referring to FIG. 5, the grating antagonist is composed of a plurality of combined grating antagonists, and may have a predetermined distance between the combined blocks in consideration of the welding and painting work space between blocks. Here, the inter-block workspace arrangement can determine the position and spacing based on statistical values of the size and position of the hull blocks fabricated in the actual dock, so the disclosed invention does not specifically limit the position or distance between such blocks. .

The disclosed technique can minimize the dismantling of the metal frame to move the position of the grid plate and to secure the working space.In case of interference with the block working space, the metal frame is removed after removing the wood or plastic wood on the upper surface of the metal frame flange, By removing it, a block work space can be secured, and a quick work environment for work can be constructed, and work can be performed more easily.

6 is a reference diagram for explaining a conventional tandem launching process.

Conventional tandem launching process is to place the hull block in accordance with the ship to be manufactured and welded together the hull blocks to produce the entire hull. When the hull is completed (step S110), water is injected (pouring) into the dock (step S120), and the completed hull can be docked out (step S130). When the completed hull is docked out, a process of repositioning the repetition after passing through the drainage step (step S140) is essentially required to complete the hull being manufactured (step S150). When the repetition is rearranged, a pour (step S160), a tandem movement (step S170), and a drainage (step S180) procedure are performed to move the hull under construction to the repositioned repetition.

The conventional tandem launching process has a problem in that the drainage and drainage water for the banjo rearrangement are required in addition to the essential process for the banjo rearrangement, so that the total air is long and the production cost is increased.

In addition, the conventional technique is that the concrete block is always placed at the intersection of the hull frame in order to detect the damage of the hull surface which is in contact with the wood lumber on the upper surface of the concrete block by the weight of the hull block. In order to prevent further damage due to height differences, the leveling of wood veneer is required every time. Therefore, the relocation and leveling of the antagonists must be carried out every time in order to make the antagonists be located at the intersection of the frame according to the linear and ship type for the manufacture of the ship. Also, in order to apply the tandem launch method, only two watering and draining operations have to be made in the dock, so that the completed ship can be launched and the tandem block can be moved to the launch ship's position.

7 is a reference diagram for explaining a tandem launch method according to the disclosed technology.

When the hull is completed in the tandem launching method disclosed (step S210), water can be injected (during water) into the dock (step S220), and the completed hull can be docked out (step S230). When the completed hull is docked out, the hull under construction is moved tandem (step S240) and drained (step S250).

Since the tandem launching process disclosed in FIG. 7 uses lattice cross-cutting, there is no need for repeated repositioning and leveling operations by moving the tandem block to the wire block position, thus reducing the number of times of drainage and drainage compared to the conventional tandem launching method, thereby generating the released air. Can be shortened.

8 is a flowchart illustrating a tandem launch method according to an embodiment of the disclosed technology.

Referring to FIG. 8, the tandem launching method using the prefabricated lattice lumber includes installing a first prefabricated lattice lumber for drying the completed hull and a second prefabricated lattice lumber for drying at least a portion of the hull at the bottom of the dock. (Step S310), positioning the plurality of ship blocks using the first prefabricated lattice lumber in the dock and welding-connecting to dry the first hull (step S320), the second using the second prefabricated lattice lumber in the dock Drying at least part of the hull (step S330) and when the first hull is completed, watering and draining the dock to dock out the first hull and to move the second hull to the position of the first prefabricated lattice antagonist; (Step S340).

Here, the step of drying the first hull (step S320) and the step of drying at least a portion of the second hull (step S330) may be performed at the same time.

Here, the prefabricated lattice object is as described above with reference to Figures 2 to 5,

A plurality of concrete blocks are spaced apart by a predetermined distance, a plurality of metal frames are coupled to the concrete blocks of both ends, and the banjo is located on the upper surface of the metal frame to directly support the hull. Here, the plurality of metal frames may be installed to form a lattice pattern.

In one embodiment, the prefabricated lattice antagonist may have a grid size of the portion supporting the bow or stern of the hull smaller than the grid size of the portion supporting the center portion of the hull.

In one embodiment, the prefabricated lattice lumber may be installed by calculating the size, position, and distance between the grids based on data on the size of the vessels built in the dock.
