Description

Technical Field

[0001] This utility model relates to the field of mobile house technology, and in particular to a top beam component for a container-type mobile house. Background Technology

[0002] like Figure 1 As shown, container houses are generally made of steel structures, and their shape is mostly rectangular. Corner heads are installed at the four corners of the top of this rectangular structure. The two top longitudinal beams 72 and two top transverse beams 71 of the container house are connected to the corner heads 1 to form a rectangular frame structure, constituting the upper beam assembly.

[0003] Currently, container houses require rainproof design, typically with grooves in the top longitudinal beams 72 and top transverse beams 71 to collect and drain rainwater. However, due to the limited size of the top longitudinal beams 72 and top transverse beams 71, the size of the internal grooves cannot be too large, thus limiting their drainage capacity per unit time. During heavy rainfall, rainwater overflows from the grooves onto the top surface of the container house (i.e., the inner side of the aforementioned rectangular frame structure), posing a risk of leakage. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to propose an upper beam component for a container-type mobile house, which can effectively prevent rainwater from overflowing onto the top surface of the container-type mobile house, effectively reduce the risk of water leakage in the container-type mobile house, and is highly practical.

[0005] The technical solution of this utility model is achieved as follows: a top beam assembly for a containerized mobile house, including a top corner head and a beam body;

[0006] The upper corner head has a hollow structure inside; the upper corner head has a drain outlet communicating with the hollow structure; the upper corner head has at least one mating surface; the mating surface has a groove communicating with the hollow structure.

[0007] The beam is provided with a water collection trough extending along its length; the beam has a docking state with the docking surface facing each other; in the docking state, the water collection trough is connected to the trough opening.

[0008] The water collection tank has a bottom wall, a top opening opposite the bottom wall, a first water-retaining side wall formed on the bottom wall and located on the inner side of the bottom wall in the width direction, and a second water-retaining side wall formed on the bottom wall and located on the outer side of the bottom wall in the width direction; the top surface of the first water-retaining side wall is higher than the top surface of the second water-retaining side wall.

[0009] Furthermore, the water collection trough has a water-retaining top wall; the water-retaining top wall extends from the top of the first water-retaining side wall toward the second water-retaining side wall and partially covers the top opening.

[0010] Furthermore, the beam is integrally formed by bending sheet metal.

[0011] Furthermore, the drain outlet is located on the bottom surface of the upper corner head.

[0012] Furthermore, the upper corner head has two adjacent mating sides; a beam is provided for each mating side.

[0013] Furthermore, the upper beam assembly includes bolts; the mating surface is provided with a plurality of assembly holes; the bolts are inserted into the assembly holes and have a pre-installed position; in the pre-installed position, a preset gap is formed between the head of the bolt and the mating surface;

[0014] A flange plate is provided on the connecting end of the beam; the flange plate has mating holes corresponding to the bolts; the mating holes include a locking hole, a clearance hole located next to the locking hole, and a passage connecting the locking hole and the clearance hole; the diameter of the locking hole is adapted to the outer diameter of the bolt shank; the diameter of the clearance hole is larger than the outer diameter of the bolt head; the width of the passage is larger than the outer diameter of the bolt shank.

[0015] The flange plate is fitted onto the bolt through a mating hole and placed in a preset gap; the flange plate is movably disposed in the preset gap, having a disassembly and assembly position that aligns the clearance hole with the head of the bolt, and a pre-positioning position that allows the bolt shank to enter the locking hole.

[0016] Furthermore, the bolt has a fastening position that moves within the mounting hole and away from the pre-installed position; in both the pre-installed and fastening positions, the bolt locks the flange plate onto the upper corner head.

[0017] Furthermore, the bolt is threaded into the mounting hole.

[0018] Furthermore, a positioning pin is provided on the mating surface; the positioning pin has a positioning end exposed on the mating side; a positioning hole is provided on the flange plate; at the predetermined positioning position, the positioning hole and the positioning pin are inserted into each other.

[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] 1. This utility model utilizes the combined use of a beam and an upper corner head. A cavity structure is arranged at the upper corner head, allowing rainwater to be collected by a water collection trough on the beam and enter the cavity structure before being drained through a drain outlet. Furthermore, in the specific structural design, the top surface of the first water-retaining sidewall of the water collection trough is higher than the top surface of the second water-retaining sidewall. When rainfall is heavy, the first water-retaining sidewall can prevent rainwater in the water collection trough from flowing into the inside of the mobile house and guide the rainwater in the water collection trough to drain outwards from the mobile house. The combination of these methods effectively prevents rainwater from overflowing onto the roof of the container-type mobile house, effectively reducing the risk of leakage and demonstrating strong practicality.

[0021] 2. This utility model utilizes the combined use of flange plates and bolts. Each bolt is pre-installed on the upper corner head, and the flange plates on each beam can be fitted onto the bolts through clearance holes, entering a pre-set gap between the bolt head and the mating side. By moving the flange plate within the pre-set gap, the bolt shank can pass through a passageway into the locking hole, thus completing the pre-positioning of the beam on the upper corner head. Furthermore, by moving the flange plate within the pre-set gap, the bolt head aligns with the clearance hole, allowing the flange plate to be disengaged from the bolt. This combination of methods allows the top crossbeams, top longitudinal beams, and other beams to be pre-positioned on the upper corner head using bolts, and then locked onto the upper corner head with bolts. This enables rapid assembly of each beam with the upper corner head, saving time and labor, increasing assembly efficiency, and effectively meeting the on-site assembly needs of prefabricated houses.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] like Figure 2-6 The diagram shows the top beam assembly of a container house according to this embodiment. The top beam assembly includes corner heads 1 and beams 2. The corner heads 1 are installed at the four corners of the container house's top. The corner heads 1 are made of metal. A cavity structure 12 is machined inside the corner heads 1. Drainage outlets 14 communicating with the cavity structure 12 are machined on the bottom surface of the corner heads 1. Two adjacent mating surfaces 11 are located on the outer surface of the corner heads 1. These two mating surfaces 11 face laterally and longitudinally, respectively. Grooves 13 communicating with the cavity structure 12 are machined on the mating surfaces 11. A beam 2 is arranged corresponding to each mating surface 11. One end of each beam 2 can connect with a mating surface 11, thus forming a mating state. In this mating state, the two beams 2 extend laterally and longitudinally, respectively, thus forming the top horizontal beam and top vertical beam of the container house.

[0032] In this embodiment, a water collection trough extending along the length of the beam 2 is formed on the beam 2. When the beam 2 is in the aforementioned docking state, the water collection trough is connected to the slot 13. Through the above structural design, rainwater can enter the water collection trough and be guided by the water collection trough through the slot 13 into the cavity structure 12 of the upper corner 1, and then discharged through the drain outlet 14.

[0033] In the specific structural design, beam 2 is integrally formed by sheet metal bending. The water collection trough has a bottom wall 21, a top opening opposite to the bottom wall 21, a first water-retaining sidewall 22 formed on the bottom wall 21 and located on its inner side in the width direction, and a second water-retaining sidewall 23 formed on the bottom wall 21 and located on its outer side in the width direction. When beam 2 is in the connected state, the first water-retaining sidewall 22 and the second water-retaining sidewall 23 both extend vertically to block rainwater in the water collection trough. The inner side of the bottom wall 21 in the width direction faces the top of the container house, and the outer side of the bottom wall 21 in the width direction faces away from the top of the container house. The top surface of the first water-retaining sidewall 22 is higher than the top surface of the second water-retaining sidewall 23. With the above structural design, when rainwater overflows from the water collection trough, the first water-blocking sidewall 22 can prevent the rainwater in the water collection trough from flowing to the top of the container house, and instead discharge it preferentially from the direction of the second water-blocking sidewall 23 to the outside of the container house.

[0034] The water collection trough includes a top water-retaining wall 24. This top water-retaining wall 24 extends from the top of the first water-retaining side wall 22 towards the second water-retaining side wall 23, partially covering the top opening. The portion of the top water-retaining wall 24 between the first and second water-retaining side walls 23 that does not cover the top opening forms an inlet, allowing rainwater to enter the water collection trough through this inlet. When rainwater overflows from the water collection trough, the top water-retaining wall 24 further prevents the rainwater from flowing towards the top of the container house, thereby further reducing the risk of leakage.

[0035] In this embodiment, the bottom wall 21, the first water-blocking side wall 22, the second water-blocking side wall 23, and the water-blocking top wall 24 of the water collection tank are all integrally formed by bending.

[0036] The upper beam assembly in this embodiment includes bolts 5. Assembly holes 15 are machined on the mating surface 11 around the groove 13. Several bolts 5 are inserted through these assembly holes 15 into the mating surface 11 to form a pre-installed position. In this pre-installed position, the head of the bolt 5 is located outside the upper corner head 1, and a predetermined gap is formed between the head of the bolt 5 and the mating surface 11. Specifically, the assembly hole 15 is designed as a threaded hole, and the bolt 5 is threadedly connected to the assembly hole 15. The aforementioned pre-installed position is formed by tightening the bolt 5. Alternatively, the assembly hole 15 can be a through hole, and a nut is matched to each bolt 5. The nut is welded to the side of the upper corner head 1 facing away from the mating surface 11, so that the bolt 5 forms the aforementioned pre-installed position by threading the nut. In this embodiment, it is preferable that the bolt 5 is threadedly connected to the assembly hole 15.

[0037] Flange plates 3 are welded to both ends of beam 2. When beam 2 is mated with mating surface 11, flange plate 3 contacts mating surface 11. Each bolt 5 has a mating hole 4 machined on flange plate 3. The mating hole 4 includes a locking hole 41, a clearance hole 42 located beside the locking hole 41, and a passageway 43 connecting the locking hole 41 and the clearance hole 42. The diameter of the locking hole 41 is adapted to the outer diameter of the bolt 5 shank. The diameter of the clearance hole 42 is larger than the outer diameter of the bolt 5 head; the width of the passageway 43 is larger than the outer diameter of the bolt 5 shank. Through this structural design, flange plate 3 can be fitted onto bolt 5 via clearance hole 42. When bolt 5 is in the aforementioned pre-installed position, flange plate 3 is in an assembled state where it is fitted onto bolt 5 via clearance hole 42 and enters a preset gap. In this assembled state, the flange plate 3 can move within a preset gap. By moving the flange plate 3, the bolt 5 shank of the flange plate 3 enters the pre-positioned position of the locking hole 41 via the passage 43. At this pre-positioned position, the locking hole 41 and the bolt 5 shank are clearance-fitted, thereby allowing the flange plate 3 to be positioned on the bolt 5, and the movement of the flange plate 3 away from the mating surface 11 is restricted by the limiting fit of the bolt 5 head.

[0038] When the flange plate 3 is in the pre-positioned position, the bolt 5 is tightened so that it moves in the mounting hole 15 away from the pre-positioned position to achieve a fastened position. In this fastened position, the flange plate 3 is locked onto the upper corner head 1.

[0039] In this embodiment, in the aforementioned mating hole 4, the clearance hole 42 is located below the lock hole 41, and the passage 43 extends vertically. At the aforementioned pre-positioned position, the flange plate 3 is hung vertically on the rod of the bolt 5 located on the vertically extending surface through the lock hole 41.

[0040] In the specific structural design, a pin hole 16 is machined on the aforementioned mating surface 11. A positioning pin 51 is inserted and fixed in the pin hole 16. The positioning pin 51 is threadedly connected to the pin hole 16. The positioning pin 51 has a positioning end exposed on the mating side 11. A positioning hole 31 is machined on the aforementioned flange plate 3 corresponding to the positioning pin 51. The distance between the end face of the positioning end of the positioning pin 51 and the mating surface 11 is smaller than the aforementioned preset gap. When the flange plate 3 is pushed close to the mating surface 11 at the aforementioned predetermined positioning position, the positioning hole 31 and the positioning pin 51 can be inserted and fitted to initially position the flange plate 3 on the mating surface 11. The positioning hole 31 and the positioning pin 51 are in clearance fit so that the positioning pin 51 can move within a preset range within the positioning hole 31.

[0041] In practical use, the two beams 2 are respectively connected to the two mating surfaces 11 on the upper corner head 1 to form the top longitudinal beam and top transverse beam of the container house. When it rains, rainwater is collected by the water collection trough on the beam 2 and guided into the cavity structure 12, and then discharged through the drain outlet 14. When the rainfall is heavy, since the top surface of the first water-retaining sidewall 22 of the water collection trough is higher than the top surface of the second water-retaining sidewall 23, the first water-retaining sidewall 22 can prevent the rainwater in the water collection trough from flowing to the inside of the container house, and guide the rainwater in the water collection trough to overflow to the outside of the container house. At the same time, the top water-retaining wall 24 further prevents the rainwater in the water collection trough from flowing to the top of the container house. The combination of the above methods can effectively prevent rainwater from overflowing to the top surface of the container house, effectively reduce the risk of water leakage in the container house, and is highly practical.

[0042] During the specific assembly of beam 2, each bolt 5 is pre-installed on the assembly holes 15 of the two mating surfaces 11 of the upper corner head 1, forming a preset gap. The flange plates 3 on each beam 2 are aligned with the corresponding mating surfaces 11, and the clearance holes 42 are aligned with the bolts 5. The flange plates 3 are pushed closer to the mating surfaces 11, allowing them to be fitted onto the bolts 5 through the clearance holes 42 and into the preset gap. The position of the flange plates 3 is adjusted within the preset gap so that the bolt shank enters the locking hole 41 through the passage 43. The flange plates 3 are then pushed against the mating side, allowing the positioning holes 31 on the flange plates 3 to engage with the positioning pins 51, thus completing the pre-positioning of the flange plates 3. The above steps are repeated to complete the assembly of the laterally extending beam 2 and the longitudinally extending beam 2. Then, each bolt 5 is tightened to lock the flange plates 3 onto the upper corner head 1. By moving the flange plates 3 within the preset gap so that the heads of the bolts 5 correspond to the clearance holes 42, the flange plates 3 can be disengaged from the bolts 5. In the above manner, each beam 2 can be pre-positioned on the upper corner head 1 by bolts 5, and then locked on the upper corner head 1 by bolts 5, so as to realize the rapid assembly of beam 2 and upper corner head 1, which saves time and effort, has high assembly efficiency, and effectively meets the on-site assembly operation requirements of mobile homes.
