Description

Technical Field

[0001] The present invention belongs to the field of construction and design of shipborne LNG storage tanks, and particularly relates to a reinforcing wedge belt for assisting the installation of corrugated plates. Background Art

[0002] In the MARK type thin-film containment system, the main screen wall is a 304L stainless steel corrugated plate with a thickness of 1.2 mm. Since the main screen wall of the cargo tank has to bear environmental loads, dynamic loads caused by ship motion, etc. during the ship's voyage, it is necessary to strengthen some areas of the corrugated plate. Currently, there are two strengthening methods. One is to add rib arches on the large corrugations of the corrugated plate, and the other is to add wooden or aluminum reinforcing wedges under the corrugated plate. As shown in Figure 1 、 2 , the shaded areas are respectively the installation areas of the corrugated plates with rib arches and the installation areas of the reinforcing wedges in some cargo tanks. Currently, for a 175,000 m³ LNG carrier, the French GTT company designs nearly 70 types of combinations of reinforcing wedges, nearly 30 types for a single ship, and more than 10,000 sets are installed at the construction site. Whether in the design stage or the construction stage, for the corrugated plates, reinforcing wedges, etc. in the drawings, the verification of thousands of corrugated plate models and wedge models, and the component search and information confirmation by the construction department have increased the workload tremendously and are prone to errors. In addition, for the installation of the reinforcing wedge belt on the vertical surface and the lower inclined surface, if the wedge belt is installed in the corrugation in advance, the reinforcing wedge belt is prone to displacement and falling during hoisting or the installation of the corrugated plate. Currently, the main method used is to connect one side of the flexible secondary screen wall to one end of the wooden reinforcing wedge belt through door nails, and then nail the other side of the flexible secondary screen wall to the main layer insulation board according to the position shown in the drawing. Subsequently, cover the insulation board on the insulation board with the wedges already installed. However, affected by factors such as the deformation of the wedge belt, nailing deviation, installation error, etc., when installing the corrugated plate, a large number of wedges cannot be installed into the gaps between the rib arches of the corrugated plate at one time, and on-site repeated adjustment and alignment are required, which also causes great inconvenience to the on-site construction and affects the overall construction period. Summary of the Invention

[0003] To solve the above problems, the present invention provides a reinforcing wedge belt for assisting the installation of corrugated plates, aiming to improve the installation accuracy of the reinforcing wedge belt while improving the installation efficiency of the corrugated plate, so as to shorten the overall construction period. The technical solution adopted is:

[0009] On the edge of the stainless steel strip at the position of the small corrugation wedge block holes, multiple adjusting notches are symmetrically arranged. The two insertion pieces at the bottom of the small corrugation wedge block positioning pin pass through the long strip-shaped holes, and the other two insertion pieces are inserted into the adjusting notches. The bolt passes through the small corrugation wedge block holes and the round hole in the center of the positioning piece in turn to fix the stainless steel strip, the small corrugation wedge block positioning pin and the small corrugation reinforcing wedge block.

[0010] The small corrugation reinforcing wedge block is located in the small corrugation space of the corrugated plate, and the large corrugation reinforcing wedge block is located in the rib arch clearance space of the large corrugation. The bottom positioning pins of the small corrugation reinforcing wedge block and the large corrugation reinforcing wedge block are inserted into the gap between the top bridge plates or the gap between the insulating plate and the top bridge plate or the insulating plate adjusting groove.

[0011] Multiple large corrugation reinforcing wedge blocks are arranged between two adjacent small corrugation reinforcing wedge blocks. The spacing value between the last large corrugation reinforcing wedge block and the adjacent large corrugation reinforcing wedge block is determined according to the spacing between the small corrugation and the adjacent rib arch, and the remaining large corrugation reinforcing wedge blocks are arranged at equal intervals, and the spacing value is determined according to the rib arch spacing of the corrugated plate.

Specific implementation manner

[0038] The present invention will be further described in conjunction with the accompanying drawings.

[0039] A reinforced wedge belt for assisting the installation of corrugated plates, the reinforced wedge includes a large corrugated reinforced wedge and a small corrugated reinforced wedge, and a plurality of large corrugated reinforced wedges and small corrugated reinforced wedges are installed on a stainless steel plate strip to form a reinforced wedge belt.

[0040] As Figure 3 shown, the back of the small corrugated reinforced wedge is provided with an inwardly concave small corrugated wedge positioning groove and a stainless steel plate strip groove, and the small corrugated wedge positioning groove is matched with a small corrugated wedge positioning pin. The length of the small corrugated reinforced wedge is greater than the length of the large corrugated reinforced wedge, and a plurality of large corrugated reinforced wedges are arranged between adjacent small corrugated reinforced wedges. The number of large corrugated reinforced wedges is related to the number of rib arch gaps between large corrugations on the corrugated plate, and is the rib arch gap value plus one. As Figure 5 shown, the small corrugated wedge positioning pin is composed of a horizontally placed square positioning piece and four vertically placed square inserting pieces. The four inserting pieces are respectively fixed at the four right angles of the positioning piece. The inserting pieces are partially inserted into the positioning piece, and the four inserting pieces are in a cross shape. The top of the small corrugated wedge positioning pin is inserted into the small corrugated wedge positioning groove, playing a positioning role in the X direction, Y direction and Z direction. A round hole is opened in the center of the positioning piece, and a bolt passes through the round hole to fix the top of the small corrugated wedge positioning pin in the small corrugated wedge positioning groove.

[0041] As Figure 4 shown, the back of the large corrugated reinforced wedge is provided with an inwardly concave large corrugated wedge positioning groove and a stainless steel plate strip groove. The large corrugated wedge positioning groove is used to install the large corrugated wedge positioning pin, and the top of the large corrugated wedge positioning pin is inserted into the large corrugated wedge positioning groove, playing a positioning role in the X direction and Z direction. As Figure 6As shown in the figure, the large corrugated wedge positioning pin consists of a horizontally placed square positioning piece and two vertically placed square inserts. The two inserts are symmetrically fixed at the two right angles of the positioning piece. The insert part is inserted into the positioning piece. A round hole is opened in the center of the positioning piece, and a bolt passes through the round hole to fix the top of the large corrugated wedge positioning pin in the large corrugated wedge positioning groove.

[0042] As Figure 7 shown in the figure, multiple large corrugated wedge holes and small corrugated wedge holes are opened on the stainless steel strip. The two inserts at the bottom of the large corrugated wedge positioning pin pass through the large corrugated wedge holes, causing the stainless steel strip to sink into the stainless steel strip-shaped groove. The bolt passes through the large corrugated wedge hole and the round hole in the center of the positioning piece in sequence to fix the stainless steel strip, the large corrugated wedge positioning pin and the large corrugated reinforcing wedge.

[0043] The inserts of the large corrugated wedge positioning pin are vertically inserted into the right angles of the positioning piece. The length of the insert on one side of the positioning piece is greater than that on the other side. The longer side insert is the bottom of the large corrugated wedge positioning pin, and the shorter side insert is the top of the large corrugated wedge positioning pin. The bottom of the small corrugated wedge positioning pin is longer than the top to ensure the reliability during the installation of the reinforcing wedge belt on the insulating board.

[0044] As Figure 9 shown in the figure, the insertion hole of the small corrugated wedge positioning pin is longer than that of the large corrugated wedge positioning pin to adapt to the adjustment of the position of the small corrugated wedge. Symmetrically arranged with multiple adjusting notches at the edge of the stainless steel strip at the small corrugated wedge hole. The spacing between the multiple adjusting notches is different to adapt to different small corrugation spacing values. The two inserts at the bottom of the small corrugated wedge positioning pin pass through the small corrugated wedge holes, and the other two inserts are inserted into the adjusting notches, causing the stainless steel strip to sink into the stainless steel strip-shaped groove. The bolt passes through the small corrugated wedge hole and the round hole in the center of the positioning piece in sequence to fix the stainless steel strip, the small corrugated wedge positioning pin and the small corrugated reinforcing wedge.

[0045] The inserts of the small corrugated wedge positioning pin are vertically inserted into the right angles of the positioning piece. The length of the insert on one side of the positioning piece is less than that on the other side. The longer side insert is the bottom of the small corrugated wedge positioning pin, and the shorter side insert is the top of the small corrugated wedge positioning pin. The bottom of the small corrugated wedge positioning pin is longer than the top to ensure the reliability during the installation of the reinforcing wedge belt on the insulating board.

[0046] The small corrugated reinforcing wedge is located in the small corrugated space of the corrugated board, and the large corrugated reinforcing wedge is located in the rib arch clearance space of the large corrugation. The bottom positioning pin of the small corrugated reinforcing wedge and the bottom positioning pin of the large corrugated reinforcing wedge are inserted into the gap between the top bridge plates or the gap between the insulating board and the top bridge plates or the insulating board adjustment groove.

[0047] The thickness of the inserted piece is the same as the width of the adjustment groove of the insulating board. The specific value depends on the manufacturing tolerance of the adjustment groove of the insulating board to ensure that while inserting into the adjustment groove of the insulating board or the gap between the insulating board and the top bridge plate or the gap between the top bridge plates, the reinforcing wedge belt will not fall off. The inserted piece and the positioning piece are bonded by a low-temperature resistant adhesive or integrally formed by machining.

[0048] In an LNG carrier, for the corrugated plates that need to install reinforcing wedges and have rib arches, the adjacent small corrugation spacings are 280mm, 395.2mm, 340mm, and 480.8mm respectively. The spacings of the rib arches on the large corrugations within this range are equal, and only the spacing between the small corrugation reinforcing wedge and the first large corrugation reinforcing wedge adjacent to it is different. Therefore, for the multiple adjustment notches set on the stainless steel strip, after the inserted piece of the small corrugation wedge positioning pin is inserted into the notch, the spacing between the small corrugation reinforcing wedge and the large corrugation reinforcing wedge can be flexibly adjusted to meet the four types of small corrugation spacing of the corrugated plates. During installation, first assemble the small corrugation wedge positioning pin with the small corrugation reinforcing wedge in alignment, and the large corrugation wedge positioning pin with the large corrugation reinforcing wedge in alignment. Then, according to the number and position of the stainless steel strip-shaped holes on the stainless steel strip, insert the bottom of the large corrugation wedge positioning pin into the stainless steel strip-shaped hole, and insert the inserted piece of the small corrugation wedge positioning pin into the corresponding adjustment notch according to the type of the basic unit of the reinforcing wedge belt to be assembled. Finally, fix each reinforcing wedge with stainless steel screws.

[0049] The width and height of the small corrugation reinforcing wedge are adapted to the space of the small corrugations of the corrugated plate, and the length, width, and height of the large corrugation reinforcing wedge are adapted to the space of the large corrugations and the rib arch gap of the corrugated plate.

[0050] As Figure 14 shown, for the four basic units of the assembled reinforcing wedge belt, the spacing a between the large corrugation reinforcing wedges depends on the rib arch spacing of the corrugated plate, and the values of b, c, d, and e depend on the spacing between the small corrugations and the adjacent rib arches, and it is ensured that the first and the last large corrugation reinforcing wedges will not enter the processing deformation area of the corrugated plate torsion node. The length of the stainless steel strip can be uniformly produced according to the 480.8mm type, and the excess stainless steel strip can be bent and spot-welded on-site, or prefabricated into four standard lengths by the manufacturer.

[0051] As Figures 10 - 13As shown in the figure, when constructing the thin-film type cargo containment system, first bond the insulation board 19 on the inner bottom of the ship's hull, and then install the top bridge plate 20 on the top bridge plate installation area 21 formed between the main layers of adjacent insulation boards 19 to ensure the integrity of the main insulation layer. After the main insulation layer is laid, an insulation board and top bridge plate gap 23 is formed between each insulation board and the top bridge plate, and a top bridge plate gap 22 is formed between the top bridge plates. At the same time, insulation board adjustment grooves 24 for deformation and expansion are provided on both the insulation board 19 and the top bridge plate 20, and the distance between every two insulation board adjustment grooves 24 along the length direction of the insulation board 19 corresponds to the model of the self-positioning reinforcing wedge belt 18. Since the spacing of the small corrugations 27 on different types of corrugated plates is different, and there will also be various combinations of spacings on the same corrugated plate 17, when the construction workers install the self-positioning reinforcing wedge belt 18, they select the self-positioning reinforcing wedge belt 18 according to the spacing of the insulation board adjustment grooves 24 along the length direction of the insulation board 19, which is convenient for searching and adjustment. And insert the inserts of the small corrugation wedge positioning pins of the self-positioning reinforcing wedge belt 18 into the length and width directions of the insulation board 19 respectively, and insert the inserts of the large corrugation wedge positioning pins 12 into the length direction of the insulation board 19. Starting from the cross point, insert the small corrugation wedge positioning pins 7 into the insulation board adjustment grooves 24 or the insulation board and top bridge plate gap 23 or the top bridge plate gap 22, and sequentially insert the large corrugation wedge positioning pins 12 into the gaps in the length direction of the insulation board 19. After the installation of the reinforcing wedge belt 18 is completed, then install the corrugated plate 17 with the rib arch 16, and the small corrugations 27 and large corrugations 26 of the corrugated plate 17 respectively correspond to the small corrugation reinforcing wedges 1 and large corrugation reinforcing wedges 6 of the self-positioning reinforcing wedge belt 18. The self-positioning reinforcing wedge belt 18 is accurately positioned and convenient to install, and is not easily deformed after installation, which can greatly improve the one-time loading rate of the insulation board 17 and shorten the overall construction period.
