Description

TECHNICAL FIELD

[0001] The present application relates to the field of box design, in particular to a container and a construction method of a container protection layer. BACKGROUND

[0002] Generally, a container can be put into use after laying wood floor, but some containers are often required to lay a layer of steel plate on the wood floor for loading goods that are easy to wear or easy to be damp.

[0003] In addition, when loading bulk cargo in a container, it is often required to lay a layer of steel plate in the container to make the container smooth and seamless, because the wood floor is often worn and has gaps when in use.

[0004] The traditional fixing method of laying a steel plate on a wood floor is to place the steel plate on the wood floor and fix it with screws. However, this fixing method has some problems. First, if the screws are screwed in too much, the steel plate may be deformed in the thickness direction, and if the screws are not screwed in enough, the protrusions on the surface of the screws will cause the surface of the steel plate to be uneven. Second, a large number of screws are used, which increases the labor and material costs, and it is difficult to pre-drill screw holes or drill holes on site, especially the pre-drilled screw holes, which may not accurately match the size of the screws (for example, if the screw hole is too large, the screw cannot be tightly fitted, resulting in connection failure). Third, when using the conventional screw connection method, the screws may loosen or jump out, which will cause connection failure, and the steel plate may shake left and right during transportation, which will cause the screws to break and cause quality problems, and it is difficult to repair. SUMMARY

[0005] Therefore, it is necessary to provide a construction method of a container and a container protection layer to solve at least some of the above problems.

[0006] A container comprises:

[0007] a floor;

[0008] positioning pins passing through the floor from preset connection points and being placed into a bottom cross beam below the floor to position and install the floor on the surface of the bottom cross beam;

[0009] a protection layer arranged on the surface of the floor, the surface of the protection layer being provided with connection through holes corresponding to the positions of the positioning pins, the two ends of the connection through holes penetrating the upper and lower surfaces of the protection layer;

[0010] welding bodies filled in the connection through holes and arranged on the upper end surfaces of the positioning pins to fix and connect the hole walls of the connection through holes and the positioning pins.

[0011] In some embodiments, the positioning nails are distributed in the middle area of the floor, and the welding bodies are filled in the connecting through holes.

[0012] In some embodiments, the positioning nails are distributed along the longitudinal centerline of the floor, the longitudinal centerline is consistent with the length direction of the container, and the longitudinal centerline is arranged between the two side walls extending along the length direction and has equal distance from the two side walls respectively.

[0013] In some embodiments, the protective layer comprises a plurality of spliced plate bodies arranged along the length direction, each spliced plate body has three or more connecting through holes, each connecting through hole is arranged along the longitudinal centerline of the floor, and each connecting through hole is connected with the corresponding positioning nail through the welding body.

[0014] In some embodiments, a reinforcing beam is arranged at the connecting position between the edges of adjacent floors and extends along the edge of the floor, and the protective layer surface is pre-opened at the position corresponding to the reinforcing beam to form a connecting through hole, so that the welding body is filled and arranged on the upper surface of the reinforcing beam at the pre-set connecting point.

[0015] In some embodiments, the pre-set connecting point on the upper surface of the reinforcing beam is arranged along the longitudinal centerline of the upper surface of the reinforcing beam, the longitudinal centerline is consistent with the length direction of the reinforcing beam, and the distance between any point on the longitudinal centerline and the two side edges of the upper surface of the reinforcing beam in the width direction is equal.

[0016] In some embodiments, the cross section of the reinforcing beam is Ω-shaped, the wing plates on the two sides in the width direction are welded to the bottom beam, and the floor is overlaid on the surface of the wing plate.

[0017] In some embodiments, the edge of the protective layer is provided with a lap joint edge, the lap joint edge is connected to the upper surface of the bottom beam of the rear end door of the container around the periphery of the floor; in the direction away from the floor, the upper surface of the bottom beam of the rear end door gradually inclines downward.

[0018] In some embodiments, the length L of the lap joint edge on the surface of the bottom beam of the rear end door is 20 mm.

[0019] In some embodiments, the side edge of the floor can be bonded with the side of the bottom frame of the container through sealing glue, and the lower surface of the protective layer is welded to the upper surface of the bottom frame of the container.

[0020] A construction method of a protective layer of a container, comprising the following steps:

[0021] An opening tool is prepared corresponding to the pre-set connecting point, the opening tool comprises a tool plate and a plurality of positioning columns arranged on the surface of the tool plate, and each positioning column corresponds to each connecting point distributed on the floor respectively.

[0022] The tool plate is laid horizontally, and the positioning columns are arranged upwards, the opening transfer marks are applied on the end faces of the positioning columns, and the protective layer is covered on the tool plate so that the surface of the protective layer is in contact with the end faces of the positioning columns, thereby transferring the opening transfer marks to the surface of the protective layer to form opening marks, and connecting through holes are formed at positions corresponding to the opening marks on the surface of the protective layer.

[0023] The welding bodies are formed in the connecting through holes by welding, so that the hole walls of the connecting through holes are connected with the connecting point positions.

[0024] In some embodiments, the connecting through holes corresponding to the positioning pins have the centers of the opening marks as the centers and diameters less than or equal to the diameters of the end faces of the positioning pins.

[0025] In some embodiments, the opening tool corresponding to the positions of the connecting point positions is prepared in advance, including:

[0026] The positioning transfer marks are applied on the end faces of the positioning pins, and the tool plate is covered on the floor so that the surface of the tool plate is in contact with the end faces of the positioning pins, thereby transferring the positioning transfer marks to the surface of the tool plate to form marks, and positioning columns are welded at positions corresponding to the marks, respectively, and the diameters of the positioning columns are equal to the diameters of the corresponding marks.

[0027] The container and the construction method have at least the following beneficial technical effects:

[0028] (1) In the embodiment, the preset connecting through holes correspond to the positioning pins one by one, the lower surface of the protective layer can be connected with the upper surface of the floor, and the protective layer is firmly connected to the bottom cross beam through the welding bodies and the positioning pins, thereby preventing the whole steel floor from being deformed in waves. Since screws are not used, the problem that the protective layer is deformed due to excessive screwing of the screws or the surface of the screws protrudes due to insufficient screwing length, thereby causing the surface of the protective layer to be uneven, can be prevented.

[0029] In the embodiment, only a small number of connecting through holes and positioning pins need to be set at the preset connecting point positions, the operation is easy, and the workload is very low; and the operation difficulty is reduced, and the problem that the dimensions of the screw holes and the screws cannot be accurately matched with each other, such as the problem that the screw holes are too large and the screws cannot be tightly matched, thereby causing connection failure, can be avoided.

[0030] In this application, the protective layer and the floor are connected by point contact, rather than by fasteners such as screws. This avoids the problem of screws easily loosening and causing connection failure when using a simple screw connection method, and also restricts the positioning pins to prevent them from jumping out. As a result, the protective layer is more stable on the floor when using a welded connection, significantly reducing the possibility of vibration affecting the protective layer.

[0031] Even if the protective layer is subjected to a huge load and vibrates left and right relative to the floor, since there is only a welded body between the protective layer and the upper surface of the floor, the left and right vibration of the protective layer relative to the floor will not exert a horizontal shear force on the nail body of the positioning nail, causing the positioning nail to break. This solves the quality and safety problems caused by screw breakage at the root, and the protective layer is always firmly fixed, which also solves the problem of difficult repair of broken screws.

[0054] As shown in FIG. 1, an embodiment of the present application provides a container, which comprises: Figures 1-4

[0055] a floor 10;

[0056] positioning nails 100, which pass through the floor 10 from preset connecting points and are placed into a bottom cross beam 20 below the floor 10, so as to position and install the floor 10 on the surface of the bottom cross beam 20;

[0057] a protective layer 30, which is arranged on the surface of the floor 10, and a connecting through hole 32 is provided on the surface of the protective layer 30 at a position corresponding to the positioning nail 100, and the two ends of the connecting through hole 32 pass through the upper and lower surfaces of the protective layer 30;

[0058] a welding body 200, which is filled in the connecting through hole 32 and is arranged on the upper end surface of the positioning nail 100, and is used for fixing and connecting the hole wall of the connecting through hole 32 and the positioning nail 100.

[0059] In the specific construction, the floor 10 is first laid on the surface of the bottom cross beam 20, the positioning nail 100 is punched after the hole is opened on the surface of the floor 10, and the floor 10 is connected with the bottom cross beam 20, and a bottom frame 1-1 is arranged on the periphery of the floor 10.

[0060] ​The protective layer 30 is pre-drilled / cut with connecting through holes 32, and then pushed into the container 1, so that the preset connecting through holes 32 correspond to the positioning nails 100; finally, the welding body 200 is filled in the connecting through holes 32 and applied to the upper end surface of the positioning nail 100, for fixedly connecting the hole wall of the connecting through hole 32 and the upper end surface of the positioning nail 100.

[0061] It is worth noting that the protective layer 30 used can be a steel plate or other wear-resistant material plate, which is not limited here.

[0062] (1) In this embodiment, the preset connecting through holes 32 correspond to the positioning nails 100 one by one, and the lower surface of the protective layer 30 can be connected with the upper surface of the floor 10, and the protective layer 30 is firmly connected to the bottom cross beam 20 through the welding body 200 and the positioning nail 100, preventing the whole steel plate from being deformed in waves. Since no screws are used, the problem that the protective layer 30 is deformed due to excessive screwing or the surface of the protective layer 30 is uneven due to insufficient screwing length can be avoided.

[0063] (2) In this embodiment, only a small number of connecting through holes 32 and positioning nails 100 need to be set at the preset connecting points, which is easy to operate and has low workload; and no screw holes need to be drilled or screws need to be drilled on site, which reduces the difficulty of work and avoids the problem that the size of the screw hole and the screw cannot be accurately matched, such as the problem that the screw hole is too large and the screw cannot be tightly matched, resulting in connection failure.

[0064] (3) In this application, the protective layer 30 and the floor 10 are connected in point contact, rather than being connected together by screws and other fasteners, which can avoid the problem of screw loosening and connection failure when using only screws for connection, and can also limit the positioning nail 100 to prevent it from jumping out. Thus, the protective layer 30 is more stable on the floor 10 when connected by the welding body 200, significantly reducing the possibility of vibration of the protective layer 30.

[0065] Even if the protective layer 30 vibrates left and right relative to the floor when bearing a large load, since there is only the welding body 200 between the protective layer 30 and the upper surface of the floor 10, the left and right vibration of the protective layer 30 relative to the floor 10 will not exert a horizontal shear force on the nail body of the positioning nail 100, causing the positioning nail 100 to break, thus solving the quality and safety problem caused by screw breakage from the root, and the protective layer 30 is always firmly fixed, also solving the problem of difficult repair of screw breakage.

[0066] Reference Figures 1-2 In some embodiments, the positioning nail 100 has a plurality of positioning nails, which are distributed in the middle area of the floor 10, and the welding body 200 is filled in each connecting through hole 32.

[0067] Specifically, after the protective layer 30 is laid on the floor 10, only the positioning nails 100 need to be arranged in the middle area to connect the protective layer 30 and the floor 10, which is easy to operate and has low workload, and can firmly connect the protective layer 30 to the bottom beam 20.

[0068] Reference Figure 1 In some embodiments, the positioning nails 100 are arranged on the longitudinal center line of the floor 10, the longitudinal center line is consistent with the length direction of the container 1, and the longitudinal center line is arranged between the two side walls 40 extending along the length direction and has equal distance from the two side walls 40 respectively.

[0069] Specifically, the middle area is most prone to bulging deformation, and the positioning nails 100 are arranged on the longitudinal center line of the floor 10, that is, the connection points are arranged on the longitudinal center line of the floor 10, and the connecting through holes 32 arranged on the protective layer 30 are also arranged on the longitudinal center line of the floor 10, which can firmly connect the protective layer 30 to the bottom beam 20 and prevent the protective layer 30 from being deformed in a wave shape.

[0070] Reference Figure 1 In some embodiments, the protective layer 30 includes a plurality of spliced plate bodies 31 arranged in sequence along the length direction, each spliced plate body 31 has three or more connecting through holes 32, and each connecting through hole 32 is arranged along the longitudinal center line of the floor 10 and connected to the corresponding positioning nail 100 by the welding body 200.

[0071] It is difficult to ensure the position accuracy of the connecting through holes 32 arranged on the large-area protective layer 30. Therefore, in the present embodiment, the protective layer 30 is divided into a plurality of spliced plate bodies 31. It has been verified that when each spliced plate body 31 has three or more connecting through holes 32, the protective layer 30 can be firmly connected to the bottom beam 20 and achieve the effect of preventing bulging deformation.

[0072] Reference Figure 5 And Figure 6 In some embodiments, a reinforcing beam 11 is further arranged at the connection between the edges of adjacent floors 10 and extends along the edges of the floor 10, and the protective layer 30 has a connecting through hole 32 prearranged on the surface corresponding to the reinforcing beam 11 to be filled with the welding body 200 and arranged on the prearranged connection point on the upper surface of the reinforcing beam 11.

[0073] Specifically, the reinforcing beam 11 arranged at the connection between the edges of adjacent floors 10 can prevent the deformation of the floor 10, and the prearranged connection point on the upper surface of the reinforcing beam 11 and the connecting through hole 32 prearranged on the protective layer 30 can firmly connect the protective layer 30 and prevent bulging deformation.

[0074] More importantly, no positioning nails 100 are arranged at the preset connection point positions on the upper surface of the reinforcing beam 11, and the protective layer 30, the floor 10 and the bottom beam 20 are not connected together. When the box is transported and hoisted in a harsh environment, no shear force in the horizontal direction is applied to the positioning nails 100 due to the horizontal vibration of the floor 10 or the bottom beam 20, the positioning nails 100 are not broken, the relative positions of the protective layer 30, the floor 10 and the bottom beam 20 are firm, and a larger horizontal load can be borne, so that the quality safety problem caused by the force breaking of the positioning nails 100 is avoided, and the maintenance cost is also reduced.

[0075] Reference Figure 5 and Figure 6 In some embodiments, the preset connection point positions on the upper surface of the reinforcing beam 11 are arranged along the longitudinal center line of the upper surface of the reinforcing beam 11, the longitudinal center line is consistent with the length direction of the reinforcing beam 11, and the distance between any point on the longitudinal center line and the two side edges of the upper surface of the reinforcing beam 11 in the width direction is equal.

[0076] In the embodiment, the connection point positions are distributed on the longitudinal center line of the upper surface of the reinforcing beam 11, and the corresponding connection through holes 32 opened on the protective layer 30 are also distributed on the longitudinal center line of the reinforcing beam 11. The protective layer 30 can be firmly connected to the reinforcing beam 11 to prevent the protective layer 30 from being deformed in a wave shape, and the position of the connection point position on the upper surface of the reinforcing beam 11 can be avoided to be offset to cause the reinforcing beam 11 to be stressed and skewed to move.

[0077] Reference Figure 6 In some embodiments, the cross section of the reinforcing beam 11 is Ω-shaped, the wing plates 111 on the two sides in the width direction are welded to the bottom beam 20, and the floor 10 is pressed on the surface of the wing plate 111.

[0078] In the embodiment, the cross section of the reinforcing beam 11 is symmetrical, and is welded to the bottom beam 20. The welding body 200 can firmly connect the protective layer 30 to the bottom beam 20 through the reinforcing beam 11, and further reduces the probability of wave deformation of the protective layer 30.

[0079] Reference Figure 3 and Figure 4In some embodiments, the edge of the protective layer 30 is provided with a lap edge 33 which is attached to the upper surface of the container rear end door bottom beam 1-2 outside the periphery of the floor 10; in the direction away from the floor 10, the upper surface of the rear end door bottom beam 1-2 gradually inclines downward to form a slope, facilitating the pushing of goods along the slope into the container 1; in the present embodiment, the lap edge 33 is inclined to adapt to the upper surface of the rear end door bottom beam 1-2 and is completely attached to the upper surface of the rear end door bottom beam 1-2 by welding, which can ensure sufficient connection strength, and the position of the protective layer 30 at the bottom of the container 1 is stable and firm and will not be offset or deformed, thereby preventing the connection from being damaged due to the horizontal shear force exerted on the welded body 200 when the protective layer 30 is offset.

[0080] Further, the length L of the lap edge 33 attached to the surface of the rear end door bottom beam 1-2 is 20 mm. Specifically, the length L of 20 mm can ensure sufficient connection strength and avoid increasing welding time and cost due to excessive length.

[0081] Further, the side edge of the floor 10 can be attached to the side surface 1-1a of the bottom frame 1-1 outside the periphery of the floor, and the lower surface of the protective layer 30 is welded to the upper surface of the bottom frame 1-1. Specifically, the side edge of the floor 10 can be attached to the side surface 1-1a of the bottom frame 1-1 by sealing glue, and the position of the floor 10 in the bottom frame 1-1 is stable, thereby ensuring the stability of the relative position between the protective layer 30 on the surface of the floor 10 and the bottom frame 1-1, and then the protective layer 30 is welded to the upper surface of the bottom frame 1-1, which further enhances the stability of the position of the protective layer 30. In the present embodiment, the protective layer 30 is welded to the upper surface of the bottom frame 1-1 on one side and is attached to the side surface 1-1a of the bottom frame 1-1 by the floor 10 on the other side, which is equivalent to being fixed to the side surface 1-1a and the upper surface of the bottom frame 1-1 at the same time, thereby increasing the connection dimension and the connection strength, and the position of the protective layer 30 at the bottom of the container 1 is more stable and firm, and offset or deformation is avoided, thereby preventing the connection from being damaged due to the horizontal shear force exerted on the welded body 200 when the protective layer 30 is offset.

[0082] In some embodiments, the present application provides a construction method of a container protective layer, specifically including the following steps:

[0083] (1) An opening tool corresponding to the preset connection point is prepared, the opening tool includes a tool plate and a plurality of positioning columns provided on the surface of the tool plate, and each positioning column corresponds to each connection point distributed on the floor 10;

[0084] (2) horizontally lay the jig plate, and set the positioning column upward, coat the hole transfer mark on the end face of the positioning column, and cover the protective layer 30 on the jig plate so that the surface of the protective layer 30 is fitted with the end face of each positioning column, thereby transferring the hole transfer mark to the surface of the protective layer 30 to form a hole mark, and a connecting through hole 32 is formed at the position corresponding to each hole mark on the surface of the protective layer 30;

[0085] (3) forming a welding body 200 in the connecting through hole 32 by welding, so that the hole wall of the connecting through hole 32 is connected with the connecting point position.

[0086] In the mode of the embodiment, the pre-set connecting through hole 32 on the surface of the protective layer 30 corresponds to the positioning nail 100 on the floor 10 and the pre-set connecting point position on the upper surface of the reinforcing beam 11 one by one. The connecting through hole 32 on the hole rear surface positioned by the positioning column is strictly aligned with the pre-set connecting point position on the floor 10, which ensures that the welding body 200 is completely laid on the end face of the positioning nail 100 and the pre-set connecting point position on the upper surface of the reinforcing beam 11, the welding area is large enough, and the connecting force of each connecting point position and the position of the positioning nail 100 can be guaranteed, thereby realizing the firm connection of the protective layer 30 to the bottom beam 20, and achieving the effect of preventing bulging deformation,

[0087] The embodiment can avoid the position deviation between the positioning nail 100 of the connecting point position and the connecting through hole 32, which leads to insufficient welding area and connection fracture failure, and the protective layer 30 will not be deformed at any position.

[0088] The positioning column of the embodiment protrudes from the jig plate, and the protective layer 30 is covered on the side where the positioning column is located and fitted with the end face of each positioning column, so that the hole transfer mark can be printed on the corresponding position on the protective layer 30, which is beneficial to the rapid implementation of the transfer operation.

[0089] In some embodiments, the connecting through hole 32 corresponding to each positioning nail 100 has the center of the hole mark as the center, and has a diameter less than or equal to the diameter of the end face of the positioning nail 100.

[0090] Specifically, when the diameter of the connecting through hole 32 of the embodiment is less than or equal to the diameter of the end face of the positioning nail 100, the protective layer 30 can be firmly connected to the floor 10, and at this time, the diameter of the connecting through hole 32 is small, the amount of the welding body 200 is small, and the work amount of welding the hole wall of the connecting through hole 32 is also small.

[0091] In some embodiments, the specific steps of preparing the hole jig corresponding to the position of the connecting point in step (1) include:

[0092] The end faces of the positioning nails 100 are coated with positioning transfer marks, and the tool plate is covered on the floor 10 so that the surface of the tool plate is in contact with the end faces of the positioning nails 100, thereby transferring the positioning transfer marks to the surface of the tool plate to form marks;

[0093] Positioning columns are welded at positions corresponding to the marks respectively, and the diameters of the positioning columns are equal to the diameters of the corresponding marks.

[0094] In the embodiment, the connection point positions where the positioning nails 100 are located are copied to the surface of the tool plate one by one, and the positioning columns on the hole tool formed are completely and accurately corresponding to the connection point positions on the floor 10, thereby ensuring the accuracy of the positions of the connection through holes 32 opened on the surface of the protective layer 30 by using the hole tool.
