[0033] The present invention will be further described in detail below in conjunction with the specification drawings and specific embodiments.

[0034] As Figures 1 to 4 shown: A corner fitting assembly for stacked transportation of a transportation main body includes four corner fittings provided on the transportation main body, namely two top corner fittings 1 and two bottom corner fittings 2; when multiple transportation main bodies are stacked for transportation, a corner fitting strut 3 is connected between the relatively arranged top corner fitting 1 and bottom corner fitting 2 of each transportation main body.

[0035] In this embodiment, the size of the transportation main body conforms to the container transportation standard, and the transportation main body can be a building mold, a ladder mold, a machine room mold, etc. The reason for setting the corner fitting strut 3 in this embodiment is that when each transportation main body is stacked up and down for sea transportation or stacking, especially for sea transportation, it is necessary to stack multiple layers of transportation main bodies on the ship for overall transportation to improve transportation efficiency, and each transportation main body conforms to the container transportation standard. For example, when six building molds are stacked on a sea ship, it is necessary to strengthen the strength of the corner fittings so that the whole is more stable and can bear greater forces to prevent the lower building mold from being pressed and deformed. The corner fitting strut solves this problem and can strongly support between the top corner fitting and the bottom corner fitting, greatly improving the load-bearing capacity of the corner fitting.

[0036] This embodiment will be described by taking the building mold 4 as an example:

[0037] The building mold 4 of this embodiment includes two end frames 41 and at least one long beam 42 provided between the end frames; the end frame 41 includes two columns and an upper cross beam and a lower cross beam provided between the two columns 43. The corner fitting of this embodiment includes a corner fitting main body 11 and a corner fitting seat 12, and the corner fitting main body 11 is connected to the column 43 through the corner fitting seat 12. Connection seats for connecting with the corner fitting are provided at the upper and lower positions on the front end faces of the two columns 43, and are threadedly connected with the corner fitting seat 12 of the corner fitting through the connection seats. The corner fitting main body 11 includes a lifting hole 111, a side hole 112 and an end hole 113, and the external dimensions of the corner fitting main body 11 conform to the international container standard dimensions for easy sea and land transportation. The corner fitting seat 12 is provided on the surface opposite to the side hole 112 and is fixed to the corner fitting main body 11 by welding. At least a part of the corner fitting main body 11 extends outwards along the end frame 41.

[0038] On the bottom surface of the top corner fitting 1 and the top surface of the bottom corner fitting 2, corner fitting support rod sleeves 13 are prefabricated. That is, the corner fitting support rod sleeve of the top corner fitting 1 extends downward, and the corner fitting support rod sleeve of the bottom corner fitting 2 extends upward. The outer diameter of the corner fitting support rod sleeve 13 is smaller than the inner diameter of the corner fitting support rod 3. When connecting the corner fitting support rod 3, first install the bottom corner fitting 2 on the column 43, then sleeved the corner fitting support rod 3 on the corner fitting support rod sleeve 13 of the bottom corner fitting 2, then insert the corner fitting support rod sleeve 13 of the top corner fitting 1 into the corner fitting support rod 3, and finally install the top corner fitting 1 on the column 43.

[0039] It can be understood that after the corner fitting support rod 3 is sleeved on the corner fitting support rod sleeve 13, it can be further reinforced by screws or pins.

[0040] In this embodiment, a lifting lug 31 is provided on the upper part of the corner fitting support rod 3. For example, the lifting lug 31 is set at a distance of 150 mm from the top end of the corner fitting support rod, so as to facilitate the lifting of the corner fitting support rod 3, so that the corner fitting support rod 3 can be easily connected between the top corner fitting 1 and the bottom corner fitting 2. Since the front end face of the end frame of the house mold in this embodiment needs to be provided with an outer wall 44 at other positions except for the corner fittings, holes for passing through the corner fitting support rod 3 are provided on the outer wall panel, and the lifting lug 31 is exposed.

[0041] In this embodiment, the outer part of the corner fitting support rod 3 is sprayed with anti-rust paint to prevent rusting during sea transportation.

[0042] In this embodiment, the corner fitting seat 12 extends obliquely along the corner fitting body 11. For example, the corner fitting seat of the top corner fitting extends obliquely upward and is bolt-fixed to the connecting seat on the column.

[0043] When transporting each house mold in this embodiment, first sleeve the corner fitting support rod 3 between the top corner fitting 1 and the bottom corner fitting 2, and then stack each house mold 4 for overall transportation; when transported to the construction site, remove the corner fittings and the corner fitting support rod 3 on each house mold 4 to assemble the house mold.

[0044] It can be understood that the structure of this embodiment can be used for ladder molds or machine room molds, and this structure is more suitable for ladder molds or machine room molds than for house molds, because the weights of machine room molds and ladder molds are lighter than that of house molds.

[0045] Embodiment 2

[0046] As Figures 5 to 11 shown: Different from Embodiment 1, in this embodiment, in addition to providing the corner fitting seat 12 on the side opposite to the side hole 112 on the corner fitting body 11, a supplementary beam rod connecting seat 14 is also provided on the side opposite to the lifting hole 111.

[0047] Specifically, a fixed floor is provided on the bottom surface of the housing mold 4; one side of the fixed floor is movably connected with a movable floor 45. When the movable floor 45 is retracted, it can serve as the side wall of the housing mold; when the movable floor 45 is lowered, it can serve as the bottom plate of another housing mold, thus realizing the expansion of space. Among them, both ends of the movable floor 45 are connected with beam rods 46, that is, the beam rods 46 can be directly prefabricated at both ends of the movable floor; when stacking multiple housing molds for overseas transportation, a single beam rod cannot meet the force requirements. Therefore, in this embodiment, supplementary beam rods 47 are arranged side by side on the outer side of the beam rods 46, and the two work together to greatly improve the strength. When the movable floor 45 is retracted to serve as the side wall of the housing mold 4, the beam rods 46 are threadedly connected to the side surface of the column 43 of the end frame, and the supplementary beam rods 47 are just located between the top angle member 1 and the bottom angle member 2. Therefore, on the side close to the supplementary beam rod 47, the angle member strut as described in Embodiment 1 is not provided between the top angle member 1 and the bottom angle member 2, but the supplementary beam rod 47 is directly used as the angle member strut to be connected between the top angle member 1 and the bottom angle member 2.

[0048] The angle member body 11 of the top angle member 1 is bolted to the top surface of the supplementary beam rod 47 through the supplementary beam rod connection seat 14, and the angle member body 11 of the bottom angle member 2 is bolted to the bottom surface of the supplementary beam rod 47 through the supplementary beam rod connection seat 14. The supplementary beam rod 47 is preferably designed as a channel steel structure. And on the side of the angle member far from the supplementary beam rod, the angle member strut 3 as described in Embodiment 1 is still provided. The angle member strut 3 is a circular tube structure, and the angle member strut sleeve 13 on the angle member body 11 is a cylindrical structure.

[0049] In this embodiment, when used for sea transportation, the wall thickness of the supplementary beam rod 47 is preferably not less than 6 mm to further improve the bearing capacity.

[0050] In this embodiment, in order to improve the force-bearing strength, a beam rod connection seat 15 is provided on the surface of the angle member body 11 opposite to the end hole 113. Among them, the top of the supplementary beam rod 47 is lower than the top of the beam rod 46, and the bottom of the supplementary beam rod is higher than the bottom of the beam rod 46, that is, the end of the supplementary beam rod 47 connected to the top angle member 1 is lower than the position of the beam rod 46, and the end of the supplementary beam rod 47 connected to the bottom angle member 2 extends along the beam rod 46. And the length of the beam rod 46 is less than the height of the column. The beam rod connection seat 15 on the angle member body of the top angle member 1 extends towards the top of the beam rod and is bolted to the top surface of the beam rod 46; similarly, the beam rod connection seat 15 on the angle member body of the bottom angle member 2 extends towards the bottom of the beam rod and is bolted to the bottom surface of the beam rod 46.

[0051] It can be said that in this embodiment, by connecting the column 43, the beam rod 46, the supplementary beam rod 47 and the angle member into a whole, the strength between the stacked housing molds can be greatly improved, and the deformation of the beam rod and the angle member can be prevented. The structure of this embodiment is more suitable for the overseas transportation of housing molds compared with the ladder mold and the machine room mold.

[0052] Embodiment 3

[0053] The difference from Embodiment 1 or Embodiment 2 is that the corner fitting body or the corner fitting seat is further designed into a thickened structure, so as to further improve the bearing capacity of the corner fitting.

[0054] To sum up, on the one hand, the utility model is particularly applicable to overseas transportation, greatly improving the stability when multiple transportation main bodies are stacked, and not being easily pressed and deformed; on the other hand, the structure is simple. After being transported to the construction site, only the corner fitting and the corner fitting strut need to be removed, without affecting the self-structure of the transportation main body.
