Description

Technical Field

[0001] The invention belongs to the field of assembled buildings, and in particular relates to a modular assembly component of an assembled building. Background Art

[0002] The modular assembly components of prefabricated buildings are the core functional units of prefabricated buildings. They refer to integrated building components that are designed in a standardized manner, prefabricated in factories, and quickly assembled on site. Its essence is to transform the scattered operations of traditional construction sites into industrially produced modular products, thereby achieving efficient, precise, and environmentally friendly construction.

[0003] When the existing assembled support steel beams are installed by connecting the upper and lower parts, the support steel beam is usually connected to the top of another support steel beam by hoisting. After the connection is completed, the staff bolts the pre-welded fenders between the two support steel beams, and then further welds and fixes the two support steel beams by welding at the connection of the two support steel beams. When installing the above-mentioned assembled support steel beams, after the support steel beams are lifted to a high altitude by hoisting equipment, the alignment of the support steel beam ports needs to be controlled by hoisting equipment and manual coordination. Due to the narrow manual operation space for high-altitude operations and the large size of the main body of the support steel beam, it is difficult to complete precise alignment in one go. The support steel beam may need to be adjusted multiple times, which is not only difficult to operate, but also frequently adjusting the docking position of the support steel beam greatly increases the safety risk.

[0026] The following is combined with Figure 1 -Attached Figure 7 The present application is further described in detail.

[0027] Please refer to Figure 1 , a modular assembly component for assembled buildings, an outer support module 1 installed on the circumference of the upper and lower support steel beams (upper support steel beam and lower support steel beam) and an inner support module 2 installed in the upper and lower support steel beams, the outer support module 1 and the inner support module 2 are connected together 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 docking assembly, the outer support module 1 and the inner support module 2 pre-installed on the lower support steel beam cooperate to first guide the docking of the upper support steel beam, and then weld the upper and lower support steel beam port connection after docking, and then the outer support module 1 and the inner support module 2 can be adjusted to further reinforce the connection between the two.

[0028] See also Figure 1 and Figure 2 There are four groups of external support modules 1 evenly distributed on the four sides of the upper and lower support steel beams. The external support module 1 includes a triangular support seat 11 welded on the side wall of the lower support steel beam, and an external guide frame 12 is fixedly arranged between the triangular support seat 11 and the corresponding side wall of the lower support steel beam.

[0029] See also Figure 2 and Figure 5The outer guide frame 12 includes a locking seat 121 slidably arranged on the upper side of the horizontal section of the triangular support seat 11, and a top support plate 122 is hinged on the locking seat 121. A connecting shaft 1 is rotatably arranged on the side of the top support plate 122 away from the locking seat 121, and both ends of the connecting shaft 1 are fixedly arranged with an outer guide seat 123, and a fixing seat 124 is hinged on the outer guide seat 123. The side of the outer guide seat 123 close to the fixing seat 124 is set in a semicircular shape, and the fixing seat 124 is welded to the corresponding side wall of the lower supporting steel beam.

[0030] See also Figure 5 A slide groove is provided on the upper side of the horizontal section of the triangular support seat 11 along its length direction, a guide rod is fixedly arranged in the slide groove, a locking seat 121 is slidably arranged in the guide rod, and a plurality of locking holes are provided on the upper side of the horizontal section of the triangular support seat 11 along the extension direction of the slide groove, a locking bolt 8 is provided on the locking seat 121, and the locking bolt 8 passes through the corresponding locking hole and is threadedly connected with a locking nut (not shown in the figure).

[0031] In specific operation, when docking: a single outer guide frame 12 forms a triangular structure through the triangular support seat 11, the 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 contacts 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 are tilted outward, the eight outer guide seats 123 form an inner inclined surface that guides inward in pairs. The four inner inclined surfaces cooperate together to guide the outer walls of the four sides of the upper support steel beam inward, such as Figure 2 shown.

[0032] When fixing, after the upper support steel beam is aligned with the lower support steel beam, the staff uses a welding gun 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 seat 121 is unlocked by rotating the locking bolt 8 in the reverse direction, and then the locking seat 121 is slid along the slide groove to the next locking hole, and then the locking bolt 8 is rotated forward to fix the locking seat 121. The movement of the locking seat 121 will cause the top support plate 122 to rotate while driving the corresponding two outer guide seats 123 to rotate and finally fit on the outer wall of the upper support steel beam, and be fixed to the inner guide frame 22 through the bolt assembly 3, as shown in FIG. Figure 3 shown.

[0033] See also Figure 1 and Figure 5In order to facilitate the positioning and installation of the two fixing seats 124, positioning strips 9 are fixedly arranged on both outer sides of the triangular support seat 11. The positioning strips 9 are fixedly connected to the corresponding side walls of the lower supporting steel beam. A positioning notch is provided on the positioning strip 9, and the fixing seats 124 are engaged with the corresponding positioning notches. After the triangular support seat 11 is installed and welded at a predetermined position, the positioning strips 9 on both sides of the triangular support seat 11 are simultaneously welded to the side walls of the lower supporting steel beam, and then the positioning grooves on the fixing seat 124 can be directly aligned with the positioning notches on the positioning strips 9 for plugging, the installation position of the fixing seat 124 can be locked, and then the fixing seat 124 can be welded to the corresponding side walls of the lower supporting steel beam.

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

[0035] See also Figure 6 and Figure 7 The inner guide frame 22 includes a cross connecting frame 221 composed of two connecting rods. The cross connecting frame 221 is fixedly arranged inside the upper outer frame 211. A sliding sleeve 222 and a limit plate 223 for limiting the sliding sleeve 222 are fixedly arranged on each section of the cross connecting frame 221. A top support plate 224 is hinged on the sliding sleeve 222. The side of the top support plate 224 away from the sliding sleeve 222 is hinged with an inner guide plate 225. A connecting shaft 2 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 connecting shaft 2.

[0036] In specific operation, when docking: the inner guide plate 225 is in an inclined state when the upper supporting steel beam is not assembled, such as Figure 1As shown. At this time, the sliding sleeve 222 contacts the corresponding limit plate 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 guide channel, so that the upper support steel beam can gradually align with the lower support steel beam from the upper guide. When the upper support steel beam moves downward to align with the lower support steel beam, the inner guide plate 225 contacts 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 close to 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 2, so that the inner guide plate 225 gradually rotates from the inclined state to the vertical state and finally fits with the inner side wall of the upper support steel beam. The vertical inner guide plate 225 cooperates with the inclined outer guide seat 123 to align the upper support steel beam with the lower support steel beam.

[0037] When fixed: Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the outer guide seat 123 is driven by the locking seat 121, so that the outer guide seat 123 rotates from an inclined state to a vertical state and fits with the outer wall of the upper supporting steel beam. At this time, the inner and outer walls on the same side of the upper supporting steel beam are respectively fitted with the outer guide seat 123 and the inner guide plate 225, and then fixed by the bolt assembly 3.

[0038] See also Figure 4 , Figure 5 and Figure 6 The corresponding bolt mounting seats 4 are fixedly provided on the opposite side walls of the two outer guide seats 123, and the inner guide plate 225 is provided with positioning holes 1 at positions corresponding to the two bolt mounting seats 4 on the same side, and a connecting nut 1 5 is welded at the end of the positioning hole 1 on the side of the inner guide plate 225 away from the corresponding bolt mounting seats 4.

[0039] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The bolt assembly 3 includes a plurality of connecting bolts 31, the threaded sections of the connecting bolts 31 are movable through the corresponding bolt mounting seats 4, the opposite side walls of the upper supporting steel beam and the corresponding positioning holes 1 in sequence and are threadedly connected with the corresponding connecting nuts 5.

[0040] During 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 supporting steel beam, the bolt mounting seat 4 fixedly connected to the outer guide seat 123 is aligned with the corresponding positioning hole 1 on the inner guide plate 225. At the same time, a through hole 1 for inserting the threaded section of the connecting bolt 31 is opened at the corresponding position of the side wall of the upper supporting steel beam. The connecting bolt 31 is installed on the bolt mounting seat 4, and then inserted into the positioning hole 1 on the inner guide plate 225 through the through hole 1. Then, the connecting bolt 31 is rotated so that the connecting bolt 31 is threadedly connected with the corresponding connecting nut 15. The same method is used to install all the 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 supporting steel beam, thereby further improving the stability between the upper supporting steel beam and the lower supporting steel beam.

[0041] See also Figure 6 and Figure 7 A guide groove 6 is provided between the outer side of the connecting vertical plate 212 and the outer side of the lower outer frame 211. The guide groove 6 has two positioning holes 2 along its length direction. A connecting nut 2 7 is welded on the inner side of the connecting vertical plate 212 and at the port corresponding to the positioning hole 2.

[0042] See also Figure 1 , Figure 3 , Figure 4 and Figure 7 The bolt assembly 3 also includes a plurality of connecting bolts 32, which are symmetrical in pairs and threadedly arranged on the side wall of the fixing seat 124 away from the lower supporting steel beam. One end of the connecting bolt 32 movably penetrates the side wall of the lower supporting steel beam and is threadedly connected with the corresponding connecting nut 7.

[0043] In the specific work, when installing the inner support frame 21, first rotate the connecting bolt 2 32 into the fixing seat 124, and the side wall of the lower support steel beam is provided with a corresponding through hole 2. The threaded section of the connecting bolt 2 32 passes through the through hole 2 and slightly protrudes from the inner wall of the lower support steel beam. The two connecting bolts 2 32 on each fixing seat 124 are installed in the above manner, and then the inner support frame 21 is inserted into the inner part of the upper support steel beam from the upper port thereof. The connecting vertical plate 212 on the peripheral side of the inner support frame 21 is slidably connected with the inner wall of the lower support steel beam, and the connecting bolt 2 32 protrudes from the inner wall of the lower support steel beam. It can slide in the guide 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 connecting bolt 232 will limit the connecting vertical plate 212, so that the connecting vertical plate 212 will not move downward any further. At this time, the end of the threaded section of each connecting bolt 232 is aligned with the corresponding positioning hole 2 in the guide groove 6, and then the connecting bolt 232 is rotated to make the connecting bolt 232 continue to move toward the positioning hole 2, and as the movement occurs, the connecting bolt 232 is threadedly connected with the corresponding connecting nut 237, thereby fixing most of the inner support frame 21 in the lower support steel beam.

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

[0045] 2. Install the inner support module 2, insert the inner support frame 21 into the lower support steel beam and lock it through the connecting bolts 32 and the corresponding connecting nuts 7.

[0046] Assembly at the construction site: the outer support module 1 and the inner support module 2 are pre-installed on the lower support steel beam, and then during the subsequent assembly at the construction site, the lower support module is installed on the ground (the specific installation method belongs to the existing technology and is not described in detail in this article), and then the upper support steel beam is hoisted by the hoisting equipment and its lower port is aligned with the upper port of the upper support steel beam, and then the lower port of the upper support steel beam will contact and guide the outer guide seat 123 and the inner guide plate 225, and the lowered upper support steel beam port guide is aligned with the port of the lower support steel beam, and then the staff welds the port connection between the two, and then connects and fixes the corresponding outer guide seat 123 and the inner guide plate 225 with the connecting bolt 31, so as to further reinforce the upper and lower support steel beams, and the internal port connection of the upper and lower support steel beams is built with an inner support frame 21, which can support the port and reduce the risk of deformation at the port.
