Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated building and a construction method thereof. Background Art

[0002] Steel structure factory buildings are a type of factory building that many industrial parks and personal factories choose to build. Short construction period and low cost are the biggest advantages of steel structure factory building construction.

[0003] The Chinese utility model patent application number CN201720012675.7 discloses a steel structure factory building, including a main body, a gate and an eaves. The main body is surrounded by walls made of thermal insulation materials, the gate is set on the wall, and the upper end of the main body is provided with a roof, which is built by steel pipes and has skylights. However, this type of factory building is time-consuming and labor-intensive to assemble, and it is inconvenient to install steel pipes.

[0004] In particular, for example, a prefabricated light steel structure factory building proposed in the patent with the authorization publication number CN115853119B is provided with a first rotating rod, a second rotating rod and a fixed plate, wherein the first rotating rod and the second rotating rod form a steel member on the fixed plate, and a plurality of steel members are arranged at intervals to form a frame assembly, and the first rotating rod and the second rotating rod have the effect of facilitating construction, thus making the frame assembly easy to build. After the frame assembly is built, the frame assembly is reinforced with a fixed assembly, and a wall is installed around the frame assembly, thereby facilitating the rapid construction of the factory building. By providing a support member and a connector, the support member can improve the stability of the second rotating rod, the connector can support and reinforce the frame assembly, and with the cooperation of the fixing member, the safety of building the factory building is improved.

[0005] The above device can achieve the purpose of rapid construction during construction, but it also has certain defects:

[0006] 1. The first rotating rod and the second rotating rod use the connecting rod as the central axis, and the stability of the connecting rod is supported by the supporting rod. This will inevitably lead to multiple pillars (supporting rods) in the middle of the constructed factory building, occupying the internal space of the factory building, while it is best for common factories to have no pillars inside.

[0007] 2. There will inevitably be a certain processing gap between the first rotating rod and the second rotating rod on the connecting rod during production. Once encountering strong winds or heavy rain, the first rotating rod and the second rotating rod will have a certain displacement in the axial direction or axial direction of the connecting rod, causing the first rotating rod and the second rotating rod to shake and vibrate, that is, the stability of the first rotating rod and the second rotating rod needs to be improved.

When the angle and position of the first frame rod are locked, the angle of the second frame rod with the first frame rod will also be locked, and no rotation, movement or shaking will occur. Therefore, the prefabricated building provided by the embodiment of the present invention can limit the rotation of the first frame rod and the second frame rod, and limit the displacement and deflection of the two, further ensuring the stability of the room-shaped structure frame.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0051] Refer to the following Figure 1 - Fig.19 The present invention describes an assembled building and a construction method thereof provided by an embodiment of the present invention.

[0052] Embodiment 1:

[0053] See also Figure 1 and Figure 2As shown, an embodiment of the present invention provides an assembled building, including a house frame 8, wherein the house frame 8 is provided in multiple groups, and multiple groups of house frames 8 are arranged side by side so that the multiple groups of house frames 8 form a house-shaped structural frame, and preferably the house frame 8 is a steel structural frame.

[0054] The single-group house frame 8 is a symmetrical structure, which includes two first frame rods 81 with one end hinged by a pin to form a V-shaped structure and a second frame rod 82 hinged at the other end of the first frame rod 81 by a second pin. The other end of the second frame rod 82 is used as a ground fixing point. It is preferred that the second frame rod 82 is fixed to the ground with anchor bolts 2, and it is preferred to assemble the base plate 1 on the second frame rod 82 to facilitate leveling of the second frame rod 82.

[0055] The symmetrical structure mentioned above refers to a symmetrical structure with the center line of the V-top of the V-shaped structure as the symmetry axis.

[0056] like Figure 1 - Figure 3 As shown, in order to ensure the stability of the house frame 8 and improve the wind and earthquake resistance of the house frame 8, a main hanging frame 5 is set. The main hanging frame 5 includes supporting columns 54 located on both sides of the house-shaped structure frame. The lower ends of the supporting columns 54 are buried underground. Three supporting columns 54 are arranged on one side of the house-shaped structure frame. The three supporting columns 54 are distributed at both ends and the middle of the house-shaped structure frame, so that the supporting columns 54 are evenly arranged relative to the house-shaped structure frame (the tension when pulling up is also relatively uniform). A transverse keel 51 is fixed between the supporting columns 54, so there are also three transverse keels 51. A longitudinal keel 52 and a secondary keel 53 are fixed above the three transverse keels 51 along the length direction of the house-shaped structure frame. The longitudinal keel 52 is opposite to the V-top of the V-shaped structure. The middle hanger is assembled on the longitudinal keel 52 for applying tension to the V-top. The secondary keel 53 is opposite to the first frame rod 81. The auxiliary hanging assembly 6 is assembled on the secondary keel 53 for applying tension to the first frame rod 81.

[0057] Therefore, the prefabricated building provided by the embodiment of the present invention can provide tension to the V-top and the first frame rod 81 of the V-shaped structure, thereby improving the support capacity of the V-top and the first frame rod 81, ensuring the stability of the prefabricated building. Compared with ground support, this pull-up method does not occupy the internal area of ​​the factory. At the same time, since the frame 8 is a prefabricated structure, it is only necessary to adjust the support angles of the first frame rod 81 and the second frame rod 82 during assembly, making the assembly of the frame 8 more convenient; and compared with the assembly method in which all steel structures in the prior art are arranged vertically and horizontally, the number of main hanging frames 5 in the present invention is relatively small, so the assembly time will be greatly shortened, improving the assembly efficiency.

[0058] Optionally, the embedded depth of the support column 54 is 60-100 cm, and the width of the support column 54 is 40-50 cm.

[0059] More specifically, in actual application scenarios, even if the first frame rod 81 and the second frame rod 82 are assembled on the pin shaft and the second frame rod 82 is assembled on the ground, once there is strong wind or heavy rain, due to the processing gap between the first frame rod 81 and the second frame rod 82 on the pin shaft, a certain degree of rotation, movement, and shaking will still occur on the first and second pin shafts, causing the entire steel structure to be unstable. Therefore, a torque limiting structure 12 is also provided on the middle hanger, and a matching portion 11 adapted to the torque limiting structure 12 is provided on the first frame rod 81, so that after the building assembly is completed, the first frame rod 81 is limited to rotate along the first pin shaft, so that the angle of the V-shaped structure formed by the two first frame rods 81 is fixed, and its wind and earthquake resistance are improved. It will no longer rotate, move, or shake on the first pin shaft. When the angle and position of the first frame rod 81 are locked, the angle of the second frame rod 82 and the first frame rod 81 will also be locked, and no rotation, movement, or shaking will occur.

[0060] Therefore, the prefabricated building provided by the embodiment of the present invention can limit the rotation of the first frame rod 81 and the second frame rod 82, and limit the displacement and deflection of the two, further ensuring the stability of the house-shaped structural frame.

[0061] Combination Figure 3 - Figure 5 As shown, the middle hanger mentioned in the embodiment of the present invention includes a main hanger assembly 7, and the main hanger assembly 7 includes a fixed shaft 77 as the above-mentioned pin shaft one, and each V-shaped structure is equipped with a fixed shaft 77, that is, each fixed shaft 77 is independently set and does not affect each other. Both ends of the fixed shaft 77 are fixed in the concave frame 71, and both ends of the concave frame 71 are provided with an inwardly bent inner roll portion 711, and the inner roll portion 711 has a through hole opposite to the concave frame 71; an axial long hole 521 is opened on the longitudinal keel 52 at a position opposite to the concave frame 71.

[0062] In this embodiment, when assembling the bolt rod 72, the bolt rod 72 is passed through the through hole of the inner roll portion 711, the through hole on the concave frame 71 and the axial long hole 521 in sequence, and then the bolt is assembled at a position on the bolt rod 72 opposite to the upper surface of the longitudinal keel 52, and then the concave frame 71 can be hoisted on the longitudinal keel 52, that is, the entire V-top is hoisted on the longitudinal keel 52.

[0063] In addition, since each house frame 8 has a separate main shaft 9, a single house frame 8 can be folded during transportation, which facilitates the transportation and storage of the prefabricated building.

[0064] The cam 75 is provided with a plurality of cams 76 which are provided at the bottom of the cam 76, and the cam 76 is provided with a plurality of cams 76 which are provided at the bottom of the cam 76. The cam 75 is provided with a plurality of cams 76 which are provided at the bottom of the cam 76. The cam 76 is provided with a plurality of cams 76 which are provided at the bottom of the cam 76. Figure 4 and Figure 5 Can understand better.

[0065] In addition, in order to ensure that the angle of the V-top is adjustable (to facilitate the folding of the first frame rod 81) in the non-assembly stage (for example, the transportation stage, the pre-assembly stage), a guide rod 2 73 is fixedly provided on the upper part of the concave frame 71 of the first frame rod 81, and a positioning plate 74 is fixedly provided on the guide rod 2 73, and a spring 1 76 is provided between the positioning plate 74 and the pressing plate 75. In this embodiment, the spring 1 76 will push the pressing plate 75 in a natural state, so that the torque limiting structure 12 on the pressing plate 75 is not in contact with the matching portion 11, and during the assembly stage, due to the extrusion of the bolt rod 72, the spring 1 76 is compressed, and the pressing plate 75 and the torque limiting structure 12 thereon are pushed close to the matching portion 11 at the upper end of the first frame rod 81, thereby realizing the axial and circumferential positioning of the V-top on the fixed axis 77.

[0066] Combination Figure 6 - Fig.11 As shown, optionally, the torque limiting structure 12 is an inserted rod structure, a toothed ring structure or a polygonal structure, and the matching portion 11 is a concave cavity structure adapted to the torque limiting structure 12 .

[0067] Combination Figure 3 and Fig.12 As shown, in order to enable the auxiliary bone 53 to generate an upward pulling force on the first frame rod 81, a groove 534 is opened on the auxiliary bone 53 at a position opposite to the auxiliary hanging assembly 6, and a sliding rod 535 is fixed in the groove 534. A C-shaped channel frame 531 is slidably arranged on the sliding rod 535, and the auxiliary hanging assembly 6 includes a pull rod 61, one end of the pull rod 61 is fixed to the first frame rod 81 by bolts, and a pull seat 62 is provided at the upper end of the pull rod 61, and the pull seat 62 includes a triangular seat 621 bolted to the C-shaped channel frame 531, that is, during assembly, the pull rod 61 passes through the hollow part of the C-shaped channel frame 531 in the vertical direction, and the triangular seat 621 is fixed on the C-shaped channel frame 531, the C-shaped channel frame 531 can generate a supporting force on the pull seat 62, thereby achieving support for the first frame rod 81.

[0068] The reason why the C-shaped slot frame 531 is set to be movable here is to facilitate its alignment with the mounting hole on the first rack rod 81.

[0069] In order to further stabilize the pull rod 61 after the auxiliary suspension assembly 6 is fixed (i.e., to limit the C-shaped channel frame 531 from sliding on the slide rod 535), a second long groove 533 is opened on the auxiliary bone 53 at both sides of the groove 534, and a first long groove 532 is opened on the auxiliary bone 53 at the rear of the groove 534, and a side seat 622 bolted to the second long groove 533 and a rear seat 623 bolted to the first long groove 532 can fix the pull seat 62 to the auxiliary bone 53, thereby locking the position of the pull seat 62 and the C-shaped channel frame 531.

[0070] like Fig.13 As shown, a waterproof board 3 is arranged above the main hanging frame 5, and an insulation board 4 is arranged outside the room-shaped structural frame.

[0071] Preferably, the waterproof board 3 is a color steel board, and the insulation board 4 is a calcium silicate board with a waterproof film attached thereto.

[0072] In this embodiment, during assembly, the second frame rod 82 of the house frame 8 is fixed to the ground by the anchor bolts 2, and the house frames 8 are fixed in sequence. A plurality of house frames 8 can form a house-shaped structure frame with a V-top, and then the main hanging frame 5 is assembled. During assembly, the supporting columns 54 are first embedded, and the anchor bolts 2 are also arranged on the supporting columns 54 to improve the stability of the supporting columns 54, and then each transverse keel 51 is fixed to the supporting column 54 by bolts, and the longitudinal keel 52 is fixed to the transverse keel 51 by bolts (the secondary keel 5 is not assembled at this time). 3), obtain the external frame, and then use the middle hanger to hang the V-top of the house-shaped structure frame on the longitudinal keel 52. Specifically, during the operation, the staff passes the bolt rod 72 from the bottom of the concave frame 71 through the concave frame 71 and continues to pass through the axial long hole 521, and then assembles the nut on the upper end of the bolt rod 72. In the above process, the bolt rod 72 will push the pressing plate 75, the spring 76 will be compressed, and the pressing plate 75 will drive the torque limiting structure 12 thereon to approach and fit on the matching part 11 at the upper end of the first frame rod 81, so that the V-top can be axially and circumferentially fixed to the fixed axis 77. The positioning of the V-top is ensured; the prefabricated insulation board 4 is then assembled on the outside of the room-shaped structural frame (and since the auxiliary hanging assembly 6 needs to be assembled later, a through hole for the tie rod 61 to pass through is pre-opened on the insulation board 4 opposite to the auxiliary hanging assembly 6); after the insulation board 4 is laid, the next step is to assemble the secondary frame 53 on the transverse keel 51 by bolts, and use the auxiliary hanging assembly 6 to hang the first frame rod 81 on the secondary frame 53. In more detail, when assembling the auxiliary hanging assembly 6, the tie rod 61 of the prefabricated auxiliary hanging assembly 6 first passes through the C-shaped slot frame 531, and pushes the C The C-shaped slot frame 531 slides on the slide bar 535 until the pull rod 61 is aligned with the through hole on the insulation board 4, and the pull rod 61 is passed downward through the through hole and the first frame rod 81, and then the nut is assembled at the lower end of the pull rod 61, and the triangular seat 621, the side seat 622, and the rear seat 623 are fixed with bolts and nuts. Of course, in actual application scenarios, the purpose of fixing the pull seat 62 can be achieved without using bolts between the triangular seat 621 and the C-shaped slot frame 531, thereby improving the convenience of assembly; finally, the waterproof board 3 is assembled to obtain the required prefabricated building.

[0073] Embodiment 2:

[0074] The difference between this embodiment and the first embodiment is that the middle hanger includes a main shaft 9 and a hanging body. The main shaft 9 is an integral shaft formed by all the pin shafts connecting the first frame rod 81, that is, all the V-tops share one shaft. The hanging body is used to hang the main shaft 9 on the longitudinal keel 52. The hanging body includes a pressing cylinder 13. The pressing cylinder 13 is sleeved on the main shaft 9, and the pressing cylinder 13 is located on both sides of the V-top. The torque limiting structure 12 is installed on the side of the pressing cylinder 13 close to the upper end of the first frame rod 81.

[0075] In this embodiment, when the pressing cylinder 13 moves close to the V-top, the torque limiting structure 12 and the matching portion 11 match, so that the two torque limiting structures 12 lock the V-top angle and the horizontal position.

[0076] Therefore, the prefabricated building provided in the embodiment of the present invention can provide tension to the V-top of the V-shaped structure, thereby improving the supporting capacity of the V-top. After the building is assembled, the first frame rod 81 is restricted from rotating along the pin axis 1, so that the angle of the V-shaped structure formed by the two first frame rods 81 is fixed, and it will no longer rotate, move, or shake on the pin axis 1. When the angle and position of the first frame rod 81 are locked, the angle between the second frame rod 82 and the first frame rod 81 will also be locked, and no rotation, movement, or shaking will occur.

[0077] In this embodiment, the hanging body has two implementation schemes, referring to Fig.14 - Fig.16 , is the first implementation scheme of the suspension body: the suspension body also includes a pull rod 10, an axial long hole 521 is opened on the longitudinal keel 52 at a position opposite to the pressure cylinder 13, one end of the pull rod 10 is fixedly connected to the pressure cylinder 13, and the other end of the pull rod 10 is assembled with a bolt after passing through the axial long hole 521, so that the pull rod 10 applies tension to the main shaft 9.

[0078] In addition, the axial long hole 521 is provided in order to improve the tolerance of assembly position deviation.

[0079] The present solution is different from the first embodiment in that the pull rod 10 and the main shaft 9 are integrated during the prefabrication stage. When the longitudinal keel 52 is assembled, the pull rod 10 is aligned with the axial long hole 521, and then the pressure cylinder 13 is pushed to make the torque limiting structure 12 and the matching part 11 match, so that the two torque limiting structures 12 lock the V-top angle and the horizontal position.

[0080] Reference Fig.17 - Fig.19The second embodiment of the hanging body: the hanging body also includes a pull rod 10, which includes an outer cylinder 101, a guide block 103 and a long strip cap 105, wherein one end of the outer cylinder 101 is integrally formed with the pressing cylinder 13, and the other end of the outer cylinder 101 is sleeved with a rod body 102 so that the rod body 102 can slide in the outer cylinder 101, and the guide block 103 is fixed to one end of the rod body 102 located in the outer cylinder 101, and the guide block 103 is between the lower end of the outer cylinder 101 and the lower end of the outer cylinder 101. A spring 2 104 is fixedly provided, and a long strip cap head 105 is rotatably installed on the upper end of the rod body 102; an axial long hole 521 for the long strip cap head 105 to pass through is opened in the height direction of the longitudinal keel 52, and a radial long groove 522 perpendicular to the axial long hole 521 is also opened on the longitudinal keel 52, and the midpoint of the axial long hole 521 coincides with the radial long groove 522, so that the long strip cap head 105 can fall into the radial long groove 522 after rotation and be limited by the radial long groove 522.

[0081] In this embodiment, when it is necessary to fix the pull rod 10 on the longitudinal keel 52, the rod body 102 can be pulled upward to move the guide block 103 in the outer tube 101, and the rod body 102 moves upward to allow the elongated cap head 105 to pass through the radial long groove 522, and then the elongated cap head 105 is rotated to enter the radial long groove 522. At this time, the radial long groove 522 can limit the elongated cap head 105 to prevent the elongated cap head 105 from continuing to rotate.

[0082] Preferably, the groove width of the radial long groove 522 here gradually decreases from top to bottom. When the elongated cap head 105 is passed upward through the radial long groove 522, the guide block 103 reaches the top of the outer cylinder 101. After the elongated cap head 105 is rotated, the elongated cap head 105 will move downward when subjected to the pulling force of the main shaft 9 below. Since the groove width gradually decreases from top to bottom, the elongated cap head 105 can enter the radial long groove 522 and be supported by the inner wall of the radial long groove 522, so that the radial long groove 522 can provide support for the elongated cap head 105 when the rod body 102 is extended to any length.

[0083] The present scheme is different from the first embodiment in that the pull rod 10 and the main shaft 9 are integrated in the prefabrication stage during assembly. When the longitudinal keel 52 is assembled, the longitudinal keel 52 will press down the rod body 102. After the longitudinal keel 52 is assembled, the pressing cylinder 13 is pushed to align the elongated cap head 105 with the axial long hole 521 (at the same time, the torsion limiting structure 12 and the matching part 11 cooperate, so that the two torsion limiting structures 12 lock the V-top angle and the horizontal position). The elongated cap head 105 can pass through the axial long hole 521, and then an upward pulling force is applied to the elongated cap head 105 while rotating the elongated cap head 105, so that the elongated cap head 105 enters the radial long groove 522 and is supported and limited by the elongated cap head 105.
