Description

Technical Field

[0001] This application relates to the technical field of containers, and more specifically to a method for laying flooring. Background Technology

[0002] Current shipping containers use multiple floor panels pieced together, which can easily trap harmful organisms in the gaps, leading to invasive species and biocontamination in the local area. Furthermore, transverse gaps require wide bottom beams for connection, and longitudinal gaps require central floor beams, increasing the overall weight of the container. To improve the existing floor structure, a single-panel design will be used; however, the current method of installing pieced flooring is not suitable for single-panel installation.

[0003] Therefore, a flooring installation method is needed to at least partially solve the above problems. Summary of the Invention

[0004] The summary section of this application introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this application is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

The laying device moves along the longitudinal direction of the container to transport the flooring from the container door to the interior of the container. The laying device places the flooring on the lifting device, which descends to the floor groove so that the flooring is laid on the base frame.

[0006] The installation method described in this application is applicable to the installation of single-piece floorboards, allowing containers to use such floorboards and thus avoiding the hiding of harmful organisms in the seams, preventing biological contamination.

[0010] Optionally, the dividing line evenly divides the upper flange of the bottom crossbeam along the longitudinal direction.

[0011] Optionally, in the positioning step, a plurality of spaced-apart second marker points are marked on the connecting line.

[0025] This application discloses a method for installing a floor 120. The floor 120 is constructed as a single piece of flooring and is used in a shipping container. The container includes a base frame 110, which includes a sill, a front sill, two bottom side beams 111 spaced apart along the transverse direction of the container, and a plurality of bottom crossbeams 112 spaced apart along the longitudinal direction of the container. The bottom crossbeams 112 are connected to the two bottom side beams 111. The installation method includes: Preparation steps: Place the container above the trench, and the lifting device installed in the trench rises from the gap between the bottom crossbeams 112 to the interior of the container.

[0026] Apply adhesive: Apply butyl adhesive to the contact surfaces of the threshold, front sill, and bottom side beam 111 that are in contact with the floor 120.

[0027] Laying steps: The laying device 140 grabs the floor 120 located at the laying station and tilts the floor 120 relative to the horizontal direction. The laying device 140 moves along the longitudinal direction of the container to transport the floor 120 from the container door to the interior of the container. The laying device 140 places the floor 120 on the lifting device, which descends to the floor groove so that the floor 120 is laid on the underframe 110.

[0028] The installation method described in this application is applicable to the installation of entire floor panels, allowing containers to use single-piece flooring and thus avoiding biological contamination caused by harmful organisms hiding in the seams. Simultaneously, since there is no need to connect the seams, the underframe 110 does not require floor center beams and wide bottom crossbeams, thereby eliminating the need for butyl rubber on these beams, reducing the amount of adhesive used, lightening the container's weight, and saving costs. By tilting the floor 120, it avoids the situation where the width of the entire floor 120 exceeds the width of the container door, preventing entry into the container.

[0029] like Figure 1 As shown, the flooring device 140 includes a moving part 141 and a gripping part 142. The gripping part 142 is rotatably connected to the moving part 141 about a rotation axis. The rotation axis is parallel to the longitudinal direction of the container. The gripping part 142 may include multiple suction cups to firmly grip the floor 120. After gripping the floor 120, the gripping part 142 rotates about the rotation axis so that the floor 120 is tilted relative to the horizontal plane, thereby providing sufficient space on both sides of the floor 120 when it enters the container door without interfering with the door.

[0030] The trench can be a depression extending downwards from the ground. A container without floor 120 is placed above the trench, allowing the interior of the container to communicate with the trench through the gaps between the bottom crossbeams 112. Multiple lifting devices are spaced apart within the trench along the longitudinal direction of the container, allowing each device to rise through the gaps between the bottom crossbeams 112 to the interior of the container to support the floor 120. Each lifting device includes a support section and a limiting section rotatably disposed on the support section. The drive section of the lifting device can drive the support section to rise and fall. During rising and falling, the support section can rotate in the vertical plane relative to the container's underframe 110. When the support section rises into the container and tilts relative to the horizontal direction, the limiting section is located on the side of the support section closest to the container's underframe 110 and tilted relative to the support section, preferably perpendicular to it, to limit the floor 120 and prevent it from slipping directly onto the support section and causing damage. The drive section of the lifting device can drive the limiting section to rotate relative to the support section, for example, driving the limiting section to rotate between perpendicular and parallel to the support section.

[0031] Specifically, the preparation steps include: the support of the lifting device rises from the gap between the bottom crossbeams 112 into the interior of the container and tilts relative to the horizontal direction, so that the limiting part is located on the side closer to the base frame 110. The tilt angle of the support relative to the base frame 110 is approximately equal to the tilt angle of the floor 120 relative to the base frame 110, and both are within the range of 30°-60°, so that the support can more stably support the floor 120.

[0032] The flooring process includes: the flooring device 140 places the floor 120 onto the support, so that the floor 120 abuts against the limiting part. Then, the limiting part rotates away from the support, causing the floor 120 to slide down and abut against the side wall of the container, while the support descends into the trench. Driven by the drive unit, the limiting part rotates in a direction parallel to the support, gradually increasing the angle between the limiting part and the support, thus gradually losing its limiting effect on the floor 120, allowing the floor 120 to slide downwards and contact the side wall of the container with one side. As the support descends into the trench, the floor 120 is automatically laid flat onto the container's underframe 110.

[0033] The threshold, front sill, and bottom side beam 111 support the four edges of the floor 120 and are initially fixed to the floor 120 with butyl adhesive to achieve a sealing effect. The contact surfaces of the threshold, front sill, and bottom side beam 111 are the upper surfaces that contact the floor 120.

[0034] The installation method also includes a loading step prior to the paving step: the loading device transports the flooring 120 to the installation station. The loading device may include a conveyor belt to transport the flooring 120 to the installation station for the paving device 140 to pick up.

[0035] Since the floor 120 will cover the bottom crossbeam 112 after being laid to the base frame 110, making it impossible to determine the position of the bottom crossbeam 112 and thus impossible to connect the floor 120 and the bottom crossbeam 112 together with fasteners, it is necessary to mark the bottom side beam 111, which will not be covered by the floor 120, according to the position of the upper flange 116 of the bottom crossbeam 112 before laying the floor 120. Figure 2 As shown, the bottom crossbeam 112 can be a C-shaped beam with an upper flange 116, a web, and a lower flange. The installation method also includes a marking step before the adhesive application step: marking first marks 113 on the two bottom side beams 111 corresponding to the dividing line of the upper flange 116 separating the bottom crossbeams 112 along the longitudinal direction of the container. The dividing line can be a virtual line used to indicate the position of the bottom crossbeam 112 in the longitudinal direction of the container. The first marks 113 can be marked at the intersections of the dividing line and the upper surfaces of the two bottom side beams 111 using tools such as chalk. In this embodiment, the first marks 113 can be marked at corresponding positions on the bottom side beams 111 based on the positions of all the bottom crossbeams 112, so that the entire bottom crossbeam 112 can be connected to the floor 120 using fasteners, achieving a secure fixation of the floor 120. It is understood that the first marks 113 can also be marked at corresponding positions on the bottom side beams 111 based on the positions of some of the bottom crossbeams 112. In this embodiment, the dividing line evenly divides the upper flange 116 of the bottom crossbeam 112 along the longitudinal direction of the container. In other words, the dividing line can be the center line of the upper flange 116 of the bottom crossbeam 112 in the longitudinal direction of the container, so that in subsequent steps, the fasteners are connected to the center of the upper flange 116 of the bottom crossbeam 112 along the longitudinal direction of the container, making the bottom crossbeam 112 more evenly stressed.

[0036] The installation method also includes a seam-closing step after the plank laying: adjusting the gaps around the perimeter of the floorboards 120 to ensure uniformity. Workers can use tools such as skewer bars to adjust the gaps around the floorboards 120. Since the floorboards 120 do not have seams, the seam-closing step only requires adjusting the gaps around their perimeter, improving work efficiency.

[0037] The installation method also includes a positioning step after the slab laying step: marking a second mark 121 on the floor 120 according to the line connecting the first mark 113 on the two bottom side beams 111. The positioning step can be done after the joint finishing step. Specifically, as... Figure 3As shown, after the floor 120 is laid onto the base frame 110, a second mark 121 is marked on the line connecting the two first mark points 113 corresponding to the same bottom crossbeam 112 using a ruler and a whiteboard marker. The position of the second mark point 121 indicates the position of the upper flange 116 of the bottom crossbeam 112. Furthermore, in the positioning step, multiple spaced second mark points 121 are marked on the connecting line, allowing the floor 120 and the bottom crossbeam 112 to be connected by multiple fasteners, ensuring a secure connection.

[0038] The installation method also includes a drilling step following the positioning step: drilling at the second mark point 121, so that the opening penetrates the upper flange 116 of the floor 120 and the bottom crossbeam 112. In this embodiment, a drilling machine can be used for drilling. The drilling machine includes multiple spaced-apart drill bits to drill at multiple second mark points 121. The drill head is mounted on a drilling machine frame and arranged at intervals along the transverse direction of the container. At the second mark point 121 of the floor 120, the motor receives a control command and drives the drill bit to rotate and feed to achieve drilling. Thus, drilling can be performed simultaneously at multiple second mark points 121 corresponding to each bottom crossbeam 112, improving work efficiency.

[0039] The installation method also includes a nailing step following the drilling step: fasteners are inserted into the holes and tightened to securely connect the floor 120 and the bottom crossbeam 112. The fasteners can be, for example, floor 120 nails. Fasteners can be manually inserted into the holes one by one and then tightened sequentially to avoid omissions. In this embodiment, a nailing machine is used for nailing and tightening. The nailing machine includes multiple spaced-apart heads that drive the fasteners into the holes and tighten them. Specifically, the heads are mounted on a nailing machine frame and spaced apart along the transverse direction of the container. The heads can be controlled to drive nails from top to bottom. During nailing, the nail feeder is first controlled to feed the fasteners into the inclined tube. The fasteners slide through the inclined tube into the positioning sleeve and remain upright. Then, the pneumatic motor receives a control command to drive the head downwards, driving the fasteners into the holes within the positioning sleeve. This allows for simultaneous nailing and tightening at multiple second marking points 121, avoiding omissions, saving manpower, and improving work efficiency.

[0040] The installation method also includes a dust removal step after the nailing step: using tools to sweep the dust on the floor 120 to the outside of the container, thereby completing the installation.

[0041] like Figure 4As shown, in another embodiment, the container includes a gooseneck trough 115. The floor 120 is installed in a similar manner to that described above. The difference is that one end of the floor 120 is supported by an angle steel connected to the main gooseneck beam 114, so butyl rubber is applied to the contact surface (upper surface) of the angle steel for contact with the floor 120 during the adhesive application step. A small floor 130 is adjacent to the gooseneck trough 115 in the transverse direction of the container. The small floor 130 is supported by a front sill, bottom side beams, and connecting angle steel. Due to the small size of the small floor 130, conventional installation methods can be used.
