Description

Technical Field

[0001] The present invention belongs to the field of prefabricated buildings, and particularly relates to a modular assembly component for prefabricated buildings. Background Art

[0002] The modular assembly component of a prefabricated building is the core functional unit in a prefabricated building, referring to an integrated building component that is prefabricated through standardized design, factory production, and quickly assembled on-site. Its essence is to transform the scattered operations at the traditional construction site into modular products of industrial production, thereby achieving efficient, precise, and environmentally friendly building construction.

[0003] When the existing prefabricated support steel beams are connected in an up-and-down manner, usually, the support steel beam is docked with the top of another support steel beam by means of hoisting. After docking, the staff bolts and fixes the wing plates pre-welded between the joints of the two support steel beams, and then further welds and fixes the two support steel beams by welding at the joints of the two support steel beams. When the above-mentioned prefabricated support steel beam is installed, after the support steel beam is lifted to a high altitude by a hoisting device, it is also necessary to control the alignment of the ports of the support steel beam through the cooperation of a lifting device and manual labor. Since the manual operation space is narrow during high-altitude operations and the main body of the support steel beam is large, it is difficult to complete precise alignment in one go, and the support steel beam may need to be adjusted multiple times. This not only makes the operation difficult but also greatly increases the safety risk due to the frequent adjustment of the docking position of the support steel beam. Summary of the Invention

[0009] According to an advantageous embodiment, bolt mounting seats are fixedly disposed on the opposite side walls of the corresponding two outer guide seats. Positioning holes one are opened at the positions on the inner guide plate corresponding to the two bolt mounting seats on the same side. A first connecting nut is welded at the port of the positioning hole one on the side of the inner guide plate away from the corresponding bolt mounting seat.

[0010] According to an advantageous embodiment, a guide groove is jointly opened between the outer side of the connecting vertical plate and the outer side of the lower outer frame. Two positioning holes two are opened along the length direction of the guide groove. A second connecting nut is welded at the port of the corresponding positioning hole two on the inner side of the connecting vertical plate.

[0011] According to an advantageous embodiment, the bolt assembly includes a plurality of first connecting bolts. The threaded sections of the first connecting bolts sequentially pass through the corresponding bolt mounting seats, the opposite side walls of the upper support steel beam, and the corresponding positioning holes one and are threadedly connected to the corresponding first connecting nuts.

[0015] Compared with the prior art, a modular assembly component for prefabricated buildings provided by an embodiment of the present invention has the following beneficial effects: 1. In the present invention, the arranged inner support module and outer support module can be pre-installed on the lower support steel beam, and when the steel beam is transported to the construction site for butt joint installation later, it is convenient for the upper support steel beam to perform high-altitude butt joint operation, improving the high-altitude butt joint accuracy of the support steel beam while reducing the high-altitude butt joint difficulty of the support steel beam.

[0016] 2.

[0026] The following further Figure 1 - attached Figure 7 gives a detailed description of the present application.

[0027] Please refer to Figure 1 , an assembled building modular assembly component, including an outer support module 1 installed on the periphery of upper and lower support steel beams (upper support steel beam and lower support steel beam) and an inner support module 2 installed inside the upper and lower support steel beams. The outer support module 1 and the inner support module 2 are jointly connected by a bolt assembly 3. By pre-installing the outer support module 1 and the inner support module 2 on the lower support steel beam, during the high-altitude hoisting and butt-joint assembly, the outer support module 1 and the inner support module 2 pre-installed on the lower support steel beam cooperate to be able to conduct butt-joint guiding on the upper support steel beam first. After butt-joint, welding is carried out at the port connection of the upper and lower support steel beams. Then, the outer support module 1 and the inner support module 2 can further reinforce the connection between the two after adjustment.

[0028] Refer to Figure 1 and Figure 2 , four groups of outer support modules 1 are provided and evenly distributed on the four sides of the upper and lower support steel beams. The outer support module 1 includes a triangular support base 11 welded on the side wall of the lower support steel beam. A common fixed outer guide frame 12 is provided between the triangular support base 11 and the corresponding side wall of the lower support steel beam.

[0029] Refer to Figure 2 and Figure 5, the outer guide frame 12 includes a locking seat 121 slidably disposed on the upper side of the horizontal section of the triangular support base 11. A first top support plate 122 is hinged to the locking seat 121. A first connecting shaft is rotatably disposed on the side of the first top support plate 122 away from the locking seat 121. Outer guide seats 123 are fixedly disposed at both ends of the first connecting shaft. A fixed seat 124 is hinged to the outer guide seat 123. The side of the outer guide seat 123 close to the fixed seat 124 is semicircular. The fixed seat 124 is welded to the corresponding side wall of the lower support steel beam.

[0030] Refer to Figure 5 , a chute is provided along the length direction on the upper side of the horizontal section of the triangular support base 11. A guide rod is fixedly disposed in the chute. The locking seat 121 is slidably disposed in the guide rod. And a plurality of locking holes are provided along the extending direction of the chute on the upper side of the horizontal section of the triangular support base 11. A locking bolt 8 is provided on the locking seat 121. The locking bolt 8 passes through the corresponding locking hole and is threadedly connected with a locking nut (not shown in the figure).

[0031] During specific operation, during docking: A single outer guide frame 12 forms a triangular structure through the triangular support base 11, the first top support plate 122 and the two outer guide seats 123. When the outer side of the lower end of the upper support steel beam abuts against the outer guide seat 123, the two outer guide seats 123 have good support stability. When the two outer guide seats 123 on the same side incline outwards, the eight outer guide seats 123 form an inwardly inclined surface that guides inwards in pairs. The four inwardly inclined surfaces can cooperate together to guide the outer walls of the four sides of the upper support steel beam inwards, as Figure 2 shown.

[0032] During fixation, after the upper support steel beam and the lower support steel beam are aligned, the staff uses a welding torch to weld the connection between the upper and lower support steel beams to preliminarily fix the upper and lower support steel beams. Then, the locking of the locking seat 121 is released by reversely rotating the locking bolt 8. Then, the locking seat 121 is slid along the chute to the next locking hole. Then, the locking bolt 8 is rotated forward to fix the locking seat 121. The movement of the locking seat 121 will cause the first top support plate 122 to rotate and at the same time drive the corresponding two outer guide seats 123 to rotate and finally fit against the outer side wall of the upper support steel beam, and be fixed to the inner guide frame 22 through the bolt assembly 3, as Figure 3 shown.

[0033] Refer to Figure 1 and Figure 5, To facilitate the positioning and installation of the two fixed seats 124, positioning bars 9 are fixedly arranged on both outer sides of the triangular support seat 11. The positioning bars 9 are fixedly connected to the side walls of the corresponding lower support steel beams. Positioning notches are formed on the positioning bars 9, and the fixed seats 124 are clamped with the corresponding positioning notches. After the triangular support seat 11 is installed at the established position and welded in place, the positioning bars 9 on both sides of the triangular support seat 11 are simultaneously welded to the side walls of the lower support steel beams. Then, the positioning grooves on the fixed seats 124 can be directly aligned with the positioning notches on the positioning bars 9 for insertion to lock the installation positions of the fixed seats 124, and then the fixed seats 124 are welded to the corresponding side walls of the lower support steel beams.

[0034] Refer to Figure 1 , Figure 4 and Figure 6 , The inner support module 2 includes a rectangular inner support frame 21 arranged between the upper and lower support steel beams. The inner support frame 21 includes outer frames 211 that are distributed up and down and are all rectangular. A plurality of connecting vertical plates 212 are fixedly arranged between the two outer frames 211. The connecting vertical plates 212 are symmetrically distributed in pairs on the same side between the two outer frames 211. Four inner guide frames 22 are arranged on the upper outer frame 211.

[0035] Refer to Figure 6 and Figure 7 , The inner guide frame 22 includes a cross-shaped connecting frame 221 composed of two connecting rods. The cross-shaped connecting frame 221 is fixedly arranged inside the upper outer frame 211. A sliding sleeve 222 is slidably sleeved on each section of the cross-shaped connecting frame 221, and a limiting disc 223 for limiting the sliding sleeve 222 is fixedly arranged. A second top support plate 224 is hinged on the sliding sleeve 222. An inner guide plate 225 is hinged on the side of the second top support plate 224 away from the sliding sleeve 222. A second connecting shaft is fixedly arranged on the upper side of the upper outer frame 211 through an ear plate, and the inner guide plate 225 is rotatably arranged on the second connecting shaft.

[0036] During specific operation, during docking: The inner guide plate 225 is in an inclined state when the upper support steel beam is not assembled, as Figure 1As shown in the figure. At this time, the sliding sleeve 222 abuts against the corresponding limiting disc 223, and the inclined inner guide plate 225 forms an outer inclined surface. The four outer inclined surfaces cooperate to guide the inner side wall of the upper support steel beam outward. The four inner inclined surfaces and the four outer inclined surfaces together form a guiding channel, enabling the upper support steel beam to gradually align with the lower support steel beam from the upper guide. During the process of the upper support steel beam moving downward to align with the lower support steel beam, the inner guide plate 225 abuts against the upper support steel beam. As the upper support steel beam moves downward, the upper support steel beam will move downward along the inner guide plate 225. When the lower side of the upper support steel beam slides to the position near the lower side of the inner guide plate 225, the upper support steel beam will force the originally inclined inner guide plate 225 to rotate along the corresponding connecting shaft two, causing the inner guide plate 225 to gradually rotate from the inclined state to the vertical state and finally fit against the inner side wall of the upper support steel beam. The vertical inner guide plate 225 and the inclined outer guide seat 123 cooperate to align the upper support steel beam with the lower support steel beam.

[0037] During fixation: As Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, the outer guide seat 123 is driven by the locking seat 121, causing the outer guide seat 123 to rotate from the inclined state to the vertical state and fit against the outer side wall of the upper support steel beam. At this time, the inner and outer side walls on the same side of the upper support steel beam are respectively in contact with the outer guide seat 123 and the inner guide plate 225, and then are fixed by the bolt assembly 3.

[0038] Refer to Figure 4 , Figure 5 and Figure 6 . Bolt mounting seats 4 are fixedly provided on the opposite side walls of the corresponding two outer guide seats 123. Positioning holes one are provided at the positions on the inner guide plate 225 corresponding to the two bolt mounting seats 4 on the same side. A connecting nut one 5 is welded at the port of the positioning hole one on the side of the inner guide plate 225 away from the corresponding bolt mounting seat 4.

[0039] Refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 . The bolt assembly 3 includes a plurality of connecting bolts one 31. The threaded sections of the connecting bolts one 31 sequentially pass through the corresponding bolt mounting seats 4, the opposite side walls of the upper support steel beam, and the corresponding positioning holes one and are threadedly connected to the corresponding connecting nuts one 5.

[0040] During the specific operation, when the vertical inner guide plate 225 and the vertical outer guide seat 123 are respectively attached to the inner and outer side walls on the same side of the upper support steel beam, at this time, the bolt mounting seat 4 fixedly connected to the outer guide seat 123 is aligned with the positioning hole on the corresponding inner guide plate 225. Meanwhile, a through hole 1 is provided at the corresponding position on the side wall of the upper support steel beam for the threaded section of the first connecting bolt 31 to be inserted. The first connecting bolt 31 is installed on the bolt mounting seat 4, then passes through the through hole 1 and is inserted into the positioning hole on the inner guide plate 225. Then, the first connecting bolt 31 is rotated so that the first connecting bolt 31 is threadedly connected to the corresponding first connecting nut 5. The same method is used to install all the first connecting bolts 31, so that the outer guide seat 123 and the inner guide plate 225 are respectively fixedly attached to the inner and outer side walls on one side of the upper support steel beam, further improving the stability between the upper support steel beam and the lower support steel beam.

[0041] Refer to Figure 6 and Figure 7 A guide groove 6 is jointly provided between the outer side of the connecting vertical plate 212 and the outer side of the lower outer frame 211. Two positioning holes 2 are provided along the length direction of the guide groove 6. A second connecting nut 7 is welded at the port of the corresponding positioning hole 2 on the inner side of the connecting vertical plate 212.

[0042] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 7 The bolt assembly 3 further includes a plurality of second connecting bolts 32. The second connecting bolts 32 are symmetrically arranged in pairs and are threadedly provided on the side wall of the fixed seat 124 away from the lower support steel beam. One end of the second connecting bolt 32 movably penetrates the side wall of the lower support steel beam and is threadedly connected to the corresponding second connecting nut 7.

[0043] During actual operation, when installing the internal support frame 21, first rotate the second connecting bolt 32 into the fixed seat 124. Through holes II are provided on the side walls of the lower support steel beams. The threaded section of the second connecting bolt 32 passes through the through holes II and slightly protrudes from the inner side wall of the lower support steel beam. Install the two second connecting bolts 32 on each fixed seat 124 in the above manner. Then insert the internal support frame 21 into the upper support steel beam from its upper port. The vertical plates 212 connected to the periphery of the internal support frame 21 are slidably connected to the inner side wall of the lower support steel beam, and the part of the second connecting bolt 32 protruding from the inner side wall of the lower support steel beam can slide in the guiding groove 6 on the connecting vertical plate 212. When the connecting vertical plate 212 moves down to a certain depth, the protruding part of the threaded section of the second connecting bolt 32 will limit the connecting vertical plate 212, so that the connecting vertical plate 212 will no longer move downward. At this time, the end of the threaded section of each second connecting bolt 32 is aligned with the corresponding second positioning hole in the guiding groove 6. Then rotate the second connecting bolt 32, so that the second connecting bolt 32 continues to move towards the second positioning hole, and as it moves, the second connecting bolt 32 is threadedly connected to the corresponding second connecting nut 7, fixing most of the internal support frame 21 inside the lower support steel beam.

[0044] The specific entire assembly process is as follows: Pre-installation: 1. Installation of the external support module 1. First, weld the triangular support base 11 at the specified position on the upper port of the lower support steel beam, and then install the fixed seat 124 at the specified position according to the positioning notch on the positioning bar 9 and weld it in place. Repeat the above method to pre-install the external support module 1 on the four sides of the upper port of the lower support steel beam.

[0045] 2. Installation of the internal support module 2. Insert the internal support frame 21 into the lower support steel beam and lock it with the second connecting bolt 32 and the corresponding second connecting nut 7.

[0046] On-site assembly: The external support module 1 and the internal support module 2 are pre-installed on the lower support steel beam. Then, during subsequent on-site assembly, the lower support module is installed on the ground (the specific installation method belongs to the prior art and will not be elaborated in this article). Then, use a hoisting device to hoist the upper support steel beam and align its lower port with the upper port of the upper support steel beam. Then, the lower port of the upper support steel beam will contact and be guided by the external guiding seat 123 and the internal guiding plate 225, guiding the downward-moving port of the upper support steel beam to align with the port of the lower support steel beam. Then, the staff welds the connection between the two ports. After that, further reinforce the upper and lower support steel beams by connecting and fixing the corresponding external guiding seat 123 and internal guiding plate 225 with the first connecting bolt 31. The internal port connection of the upper and lower support steel beams is internally provided with an internal support frame 21, which can support the port and reduce the risk of deformation at the port.

[0047] The above are only embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
