Description

Technical Field

[0001] This invention relates to the field of earthquake-resistant steel structural components, specifically an earthquake-resistant steel structural component for prefabricated residential buildings. Background Technology

[0002] In prefabricated housing, most of the steel structural components are assembled using prefabricated methods. Earthquake-resistant improvements in prefabricated housing primarily focus on enhancing the connection stability of the steel structure itself. During an earthquake, the building undergoes structural deformation, causing deformation of steel structural components such as doors. This deformation prevents people from opening steel doors in time, delaying escape. Furthermore, the inability to quickly open these doors can bury people in the collapse of the building, significantly increasing the danger during an earthquake. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a seismic-resistant steel structural component for prefabricated housing, which can solve the problems in the prior art.

[0004] This invention is achieved through the following technical solution: A seismic-resistant steel structural component for prefabricated housing includes a steel door frame. A steel door is hinged to one side of the door frame. The invention is characterized by four right-angled structural plates slidably disposed on one side of the door. A sliding mating plate is also disposed on one side of the door, slidingly engaging with the upper and lower right-angled structural plates. A movable rod is disposed on one side of the sliding mating plate, with a threaded rod slidably disposed on the outer side of each movable rod. A movable plate is disposed on one side of the threaded rod, slidingly engaging with the right-angled structural plate on one side. The invention also includes upper and lower guide plates, slidingly engaging with the right-angled structural plates. A hinge device is provided between the steel door and the door frame.

[0005] A further technical solution includes a hinge device comprising two connecting plates hinged together. Each connecting plate has multiple through holes. One connecting plate is fixed to the steel structure door frame. A loading housing is provided on one side of the steel structure door. A slot is provided inside the loading housing. The other connecting plate is slidably inserted into the slot.

[0006] A further technical solution is provided with a sliding plate on one side of the sliding mating plate, and a plurality of plug-in rods on one side of the sliding plate. The plug-in rods slide through the steel structure door and extend into the connecting plate to engage with the through hole.

[0007] A further technical solution also includes a fixing block, wherein the fixing block is provided with a guide rod on the upper and lower sides and a sliding cylinder is slidably provided on the outer surface of the guide rod, and the sliding cylinder is fixedly connected to the right-angle structural plate.

[0008] In a further technical solution, the fixed cylinder is provided with an inner hole, the threaded rod passes through the inner hole, the movable rod passes through the inner hole, and the movable rod is slidably connected to the inner hole of the threaded rod.

[0009] In a further technical solution, a fixed cylinder is provided inside the fixed block, and an outer rotating cylinder is rotatably provided on the outer surface of the fixed cylinder. A bevel gear is provided on one side of the outer rotating cylinder, and one of the threaded rods passes through the bevel gear, and the threaded rod is threadedly connected to the bevel gear.

[0010] In a further technical solution, an installation block is provided on one side of the steel structure door, and the installation block is slidably connected to the movable plate.

[0011] A further technical solution is that a steel structure plate is provided on one side of the steel structure door, the steel structure plate is fixed to the mounting block, and the movable plate, right-angle structural plate, sliding fit plate and boss are slidably connected to the steel structure plate.

[0012] In a further technical solution, a mating shaft is rotatably provided inside the steel structure plate, a rotating wheel is provided on the outer surface of the mating shaft, and a driving bevel gear is provided on one side of the mating shaft, with the driving bevel gear meshing with the bevel gear.

[0013] The beneficial effects of this invention are:

[0014] 1. By adjusting the size of the frame structure composed of a movable plate, a right-angle structural plate, a guide plate, and a sliding mating plate, the frame structure can be disengaged from the steel structure door frame. During the movement, the sliding mating plate moves and drives the sliding plate, which in turn drives the plug rod to disengage from the through hole. This allows the steel structure door to be pushed, enabling the connecting plate to separate from the loading shell. This allows personnel to quickly separate the steel structure door from the steel structure door frame, facilitating personnel escape.

[0015] Second, by setting a protrusion on one side of the sliding inner cavity and the guide plate, the protrusion is slidably connected to the sliding inner cavity. The protrusion is flush with the right-angle structural plate, so that the steel structure door frame can maintain good sealing performance when it is closed after it abuts against the right-angle structural plate and the protrusion.

Detailed Implementation

[0027] like Figures 1-9 As shown, the present invention will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationship is consistent in the up, down, left, right, front, and back directions. The present invention provides a seismic-resistant steel structural component for prefabricated housing, including a steel door frame 11. A steel door 12 is hinged to one side of the steel door frame 11. The key feature is that four right-angled structural plates 31 are slidably arranged on one side of the steel door 12, distributed at the four corners of one side of the steel door 12. A sliding mating plate 38 is also provided on one side of the steel door 12, slidingly engaging with the upper and lower right-angled structural plates 31. A moving rod 41 is provided on one side of the sliding mating plate 38, one at the top and one at the bottom. A threaded rod 36 is slidably arranged on the outer side of the moving rod 41. A moving plate 35 is provided on one side of the threaded rod 36, slidingly engaging with the right-angled structural plate 31 on its side. A hinge device is provided between the steel door 12 and the steel door frame 11.

[0028] Advantageously, the hinge device includes two connecting plates 23, which are hinged together. Multiple through holes 24 are provided in the connecting plates 23. One of the connecting plates 23 is detachably connected to the steel structure door frame 11. A loading housing 25 is provided on one side of the steel structure door 12. A slot 21 is provided in the loading housing 25. The connecting plate 23 is slidably inserted into the slot 21.

[0029] Advantageously, a sliding plate 39 is provided on one side of the sliding mating plate 38, and a plurality of plug-in rods 22 are provided on one side of the sliding plate 39. The plug-in rods 22 slide through the steel structure door 12 and extend into the connecting plate 23 to engage with the through hole 24. After the connecting plate 23 is located in the slot 21, the plug-in rods 22 can pass through the steel structure door 12 and enter the slot 21, so that the plug-in rods 22 are engaged and fixed with the through hole 24. When the steel structure door frame 11 and the steel structure door 12 are in an overlapping state and the connecting plates 23 are on the same plane, when the sliding plate 39 drives the plug-in rods 22 to move and the plug-in rods 22 are disengaged from the through hole 24, the steel structure door 12 can be separated from the steel structure door frame 11. At this time, the loading shell 25 slides away from the connecting plate 23, so that the connecting plate 23 is separated from the loading shell 25.

[0030] Advantageously, the right-angle structural plate 31 is provided with sliding inner cavity 54 at both ends, and also includes a guide plate 51 at the top and bottom. A boss 52 is provided on one side of the guide plate 51. The guide plate 51 slides into the sliding inner cavity 54. The boss 52 is flush with the right-angle structural plate 31. A limiting block 53 is provided on one side of the boss 52. The limiting block 53 is slidably engaged with the inside of the sliding inner cavity 54. The sliding mating plate 38 is slidably engaged with the sliding inner cavity 54.

[0031] Advantageously, the movable plate 35 extends into the sliding inner cavity 54 for sliding engagement.

[0032] Advantageously, a mounting block 37 is provided on one side of the steel structure door 12, and the mounting block 37 is slidably connected to the movable plate 35.

[0033] Advantageously, a steel structure plate 13 is provided on one side of the steel structure door 12. The steel structure plate 13 is fixed to the mounting block 37, and the movable plate 35, the right-angle structure plate 31, the sliding fit plate 38 and the boss 52 are slidably connected to the steel structure plate 13.

[0034] Advantageously, a fixing block 34 is provided on one side of the steel structure door 12, and a guide rod 33 is provided on the upper and lower sides of the fixing block 34. A sliding cylinder 32 is slidably provided on the outer surface of the guide rod 33, and the sliding cylinder 32 is fixedly connected to the right-angle structural plate 31.

[0035] Advantageously, a fixed cylinder 47 is provided inside the fixed block 34, and an outer rotating cylinder 42 is rotatably provided on the outer surface of the fixed cylinder 47. A bevel gear 43 is provided on one side of the outer rotating cylinder 42, and a threaded rod 36 passes through the bevel gear 43, with the threaded rod 36 and the bevel gear 43 being threadedly connected. An inner hole 61 is provided inside the fixed cylinder 47, through which the threaded rod 36 and a moving rod 41 pass through the inner hole 61, with the moving rod 41 being slidably connected to the inner hole 62 inside the threaded rod 36. By rotating the outer rotating cylinder... After 42 and bevel gear 43, the threaded rod 36 is threadedly connected to the bevel gear 43 and then slides into the inner hole 61. Under the sliding action of the frame structure composed of the moving plate 35, the right-angle structure plate 31, the guide plate 51 and the sliding fit plate 38, the sliding fit plate 38 and the moving rod 41 slide toward the fixed cylinder 47, and the moving rod 41 slides into the inner hole 62. At this time, the frame structure composed of the moving plate 35, the right-angle structure plate 31, the guide plate 51 and the sliding fit plate 38 can be reduced in size.

[0036] Advantageously, the steel structure plate 13 is provided with a mating shaft 45 for rotation, the outer surface of the mating shaft 45 is provided with a rotating wheel 15, and a driving bevel gear 46 is provided on one side of the mating shaft 45, which meshes with the bevel gear 43.

[0037] The prefabricated residential seismic steel structure allows the frame structure composed of the movable plate 35, right-angle structural plate 31, guide plate 51, and sliding mating plate 38 to slide against each other and detach from the interior of the steel structure door frame 11. Furthermore, the sliding mating plate 38 moves and drives the sliding plate 39, which in turn drives the plug rod 22 to detach from the through hole 24. This allows the steel structure door 12 to be pushed, enabling the connecting plate 23 to separate from the loading shell 25. This allows personnel to quickly separate the steel structure door 12 from the steel structure door frame 11, facilitating personnel escape.

[0038] When the frame structure composed of the movable plate 35, the right-angle structural plate 31, the guide plate 51 and the sliding mating plate 38 is at its maximum size, it can be inserted into the inside of the steel structure door frame 11, so that the steel structure door 12 and the steel structure door frame 11 have the function of opening and closing the door. The mounting block 37 is used to install the door lock.

[0039] When the frame structure composed of the movable plate 35, the right-angle structural plate 31, the guide plate 51, and the sliding mating plate 38 slides and adjusts from the maximum size to the minimum size, since the slide cylinder 32 and the guide rod 33 are inclined at 45 degrees toward the mating shafts on both sides, the right-angle structural plates 31 at the four corners can slide toward the fixed block 34, so that the movable plate 35, the right-angle structural plate 31, the guide plate 51, and the sliding mating plate 38 can slide synchronously. The movable plate 35 extends into the sliding cavity 54 of the right-angle structural plate 31, the guide plate 51 retracts into the sliding cavity 54, and the sliding mating plate 38 slides into the sliding cavity 54. The movable plate 35 and the sliding mating plate 38 move closer to the fixed block 34.

[0040] By rotating the rotating wheel 15 and then cooperating with the shaft 45, the driving bevel gear 46 is rotated. Since the driving bevel gear 46 meshes with the bevel gear 43, the outer rotating cylinder 42 is rotated, which allows the outer rotating cylinder 42 to rotate around the outer surface of the fixed cylinder 47. After the bevel gear 43 is threadedly connected to the threaded rod 36, the threaded rod 36 passes through the bevel gear 43 and slides towards the fixed cylinder 47. Meanwhile, the moving rod 41 on the other side passes through the inner hole 61 and slides into the inner hole 62, which allows the frame structure composed of the moving plate 35, the right-angle structure plate 31, the guide plate 51, and the sliding mating plate 38 to slide.

[0041] After the sliding plate 38 moves, it drives the sliding plate 39 to move, so that the plug rod 22 on one side of the sliding plate 39 slides and disengages from the through hole 24 and engages with it. This allows the connecting plate 23 to be pulled out from the loading housing 25. After the personnel push the steel structure door 12, the connecting plate 23 can slide and separate from the loading housing 25. The steel structure door 12 moves away from the steel structure door frame 11 to achieve the separation of the connecting plate 23 from the loading housing 25.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
