The width shall not be less than 2286 mm. 3.3 Corner fittings The corner fittings of the 5D type general container shall comply with GB1835-80 "Technical Conditions for Container Corner Fittings". 3.4 Bottom structure Any container equipped with bottom corner fittings shall be able to be opened by four The bottom of the container shall be supported by a bottom corner piece. When a load of 1.8R is evenly distributed on the bottom plate of the container, the depth of any part of the bottom shall not exceed 6 mm below the lower surface of the bottom corner piece. The bottom structure of the container shall be designed to withstand the various forces generated by the goods in the container during transportation, stacking and packing. 8.5 Pre-structure The top of the container shall be able to withstand the load caused by the staff working on it. The top surface of the top piece shall not protrude less than 6 meters from the highest surface of the container top. 3.6 Fork groove Published by the Taojia Standards Bureau on October 11, 1982 1983 -10-01 implementation GB 321882 5D general purpose containers must be equipped with fork plates. The fork plate should be fully penetrated through the bottom structure of the container vertically so that the forklift can lift the fork from the opposite side. It is not required to lay the fork plate along the entire length of the container, but the plate should be laid at both ends of the fork groove. The position and size of the fork plate are shown in Figure 1. 490050mm+ B305mm, ℃2102m, D 20 mm. 4 Tests 4.1 General Unless otherwise specified, containers complying with the requirements of Article 3 shall also be able to withstand the various tests specified in Articles 4.2 to 4.10. The weathertightness test shall be carried out after the other tests. The test load in the container shall be evenly distributed. The test loads specified in the following tests are the minimum requirements. 4.2 Stacking test 4.2.1 This test is to check the load-bearing capacity of the container when it is loaded with two ton containers. It takes into account the stacking conditions of railway and port container yards, the speed effect when it is stacked in the cabin grid, and the relative coding of the upper and lower containers caused by the gap between the container and the grid. 4.2.2 Method Put the container on a solid water table supported by four bottom parts of the box body, and put a uniform load of 1.000 in the box, and apply it on the lower parts, so that each corner part can bear 0.9 feet of vertical load. The angle or simulation piece at the bottom of the test chamber (with the corresponding plane size, opening, turning angle, edge angle and difference with the real object) is applied to the tested object. The angle pieces or simulation pieces should be arranged in the same side direction, with a horizontal deviation of 25.4 mm and a vertical deviation of 3 meters. Observe and measure the deformation of the bottom structure and each column. The test diagram is shown in Figure 2. $Preliminary lifting test *.3.1 GB321882 of China This test is to test the load-bearing capacity of the container by lifting from the top or lifting with a sling at an angle of 45 to the plumb line. At the same time, the bottom plate and the bottom structure of the box are tested for their ability to withstand various loads generated by the acceleration of the load in the box under the lifting operation. 4.3.2 Method The container is loaded with a uniformly distributed load of 2 feet and a ton. The sling is at an angle of 45 to the plumb line, and the four corners are lifted smoothly together. After lifting the container, it should be suspended for 5 minutes and then lowered steadily. Observe the deformation of the container body and measure the deformation of the bottom structure. The test diagram is shown in Figure 3. l2Ry 4.4 Bottom lifting test 4.4.1 GB3218-82 This test is to test the lifting capacity of the container when the lifting rope is at an angle of 6 to the water level. At the same time, it tests the bearing capacity of the bottom plate and the bottom structure of the container under the various load forces generated by the lifting operation. If the test is not required, it can be omitted. 4.4.2 Method The container is loaded with a uniformly distributed load of 2 feet and a T, and is lifted steadily through the four bottom corner fittings. The lifting force should be made to travel along the side wall of the container, and the distance between it and the outer surface of the corner fittings should not exceed 10 millimeters, but it should not touch any part of the container. The angle between the lifting force action line and the water half line is 0", and the lifting is maintained for 5 minutes, and then lowered steadily. Observe the deformation of the box and the deformation of the bottom structure of the test box. The test diagram is shown in Figure 4. Re 4.5 Longitudinal bolting test 4. 5. 13 2sin60% 2R- T 2sin60 This test is to test the bearing capacity of the container under the dynamic load of railway operation (that is, under the condition of 29 acceleration). 4.5.2 Method The container is loaded with a uniform load of RT, and the two bottom corner pieces at one end of the container are fixed on the rigid support. Then, a longitudinal horizontal force equivalent to 2 feet is applied to the two bottom corner pieces at the other end, first toward the fixed piece, and then in the opposite direction. Observe the deformation of the container and measure the length change of the two lower side beams. The test diagram is shown in Figure 5. RT 4.6 Side wall test 4.6.1 The test is to test the bearing capacity of the container side wall under the dynamic load when the ship is traveling. 4.6.2 Method A uniform load of 0.6P is applied to the inner side wall of the container. If the two side walls are symmetrical structures, only one side can be tested. If the two GB 821B82 If the side wall structure is asymmetrical, it is necessary to test the two side walls separately. Observe and measure the deformation of the side wall. The test diagram is shown in Figure 6. n.6 P. 4.7 End wall test 4.7. t's Test the bearing capacity of the container end wall for dynamic loads when the vehicle or ship is traveling. 4.7.2 Apply a uniform load of 0.6P to the inner wall of the container end. If the two end structures are different (such as a door at one end, etc.), the test should be carried out separately. Observe and measure the deformation of the entire end. The test diagram is shown in Figure 7. 9.6 , 8 Box top test 4.8.1 GB321882 Test the bearing capacity of the container when the staff is working on it. 4.8.2 Method For containers with box top strength requirements, apply a uniform load of 150 kg on the weakest area of the box top structure of 300×300 square millimeters. Observe and measure the deformation of the box top. The test diagram is shown in Figure. nsokg 4. 9 Fork lifting test 4. 9.1 Test the load-bearing capacity of the container during lifting. 4.9.2 Method Put 1.25R-T of cloth in the container, insert two fork teeth with a width of 200mm into the fork groove and support the container body, so that its effective length is 3/4 of the fork groove, support for 5 minutes and then put it down steadily. Observe the deformation of the bottom of the container. The test diagram is shown in Figure 9. J.25R-T 4.10 Uneven ground test (twisting test) 4.10.1 day Test the adaptability of the container to work on uneven ground. This test is carried out when required by the container operator or the carrier. 4.10.2 Method Put the fully loaded container (uniformly distributed load) in a three-point supported, "point suspended" state (the left bottom corner of the door is suspended once each). Check whether the container door can be opened and closed. The test diagram is shown in the figure. GB 3218-B2 The specific test requirements are determined according to the requirements of the container owner or the selection unit. Suspension 4.11 Wind and rain tightness test 4.11.1 H Check all surfaces and joints and seams of the container for leakage. 4.11.2 MethodwwW.bzxz.Net Spray water on all surfaces and seams of the container with a nozzle with an inner diameter of 12.5 mm and an outlet pressure of 100 kPa (1 kgf! virtual meter) at a distance of 1.5 m from the container support surface and a moving speed of 100 mm/s. 4.12 Test requirements 4.12, 1 After all the tests in Article 4.2 of this standard are completed, , no deformation or distortion that affects the use of any part of the container shall occur, and the requirements for loading and unloading, handling, fixing and reloading shall still be met. 12.2 After the wind and rain tightness test of 4.11, there shall be no leakage in the reinforcement.
