Description

Technical Field

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

[0002] As the construction industry continues to develop and innovate, prefabricated buildings have gradually become an important development direction in the construction field due to their many advantages such as high efficiency and environmental protection. Among them, prefabricated steel structures, as a key type of prefabricated buildings, have attracted much attention. Prefabricated steel structure buildings use steel components to construct the building structure system and abandon on-site cast-in-place nodes. This gives them significant advantages in the construction process, greatly improving the installation speed and effectively shortening the construction period, meeting the high requirements of modern society for building construction efficiency. At the same time, they have excellent seismic performance, light weight, and corresponding lower foundation costs, which can effectively reduce construction costs. After reasonable design, steel structure prefabricated buildings are more economically competitive than prefabricated concrete buildings. In addition, steel structure materials are recyclable, which is in line with the development concept of green environmental protection. They have been widely used and promoted in large-scale construction fields such as public buildings and factories. Currently, a variety of prefabricated steel structure technologies have been applied in actual projects. For example, the Chinese patent publication number "CN219863339U" discloses a prefabricated steel structure for public buildings that is easy to assemble. Through a connecting and fixing mechanism, pressing down a movable shaft drives the lower tooth plate downward to compress the spring. After inserting a trapezoidal block, the movable shaft is released, and the spring force causes the lower tooth plate to move up and engage with the upper tooth plate, thereby achieving a connection and fixation between the top plate and the horizontal I-shaped steel. This connection method ensures the stability of the connection, is easy to operate during disassembly, and does not damage the original structure of the device, making it easy to recycle and reuse. However, the existing prefabricated steel structures still have obvious limitations in practical applications. The prefabricated steel structures in the above patents have poor flexibility during splicing and installation, and can only connect to horizontal I-shaped steel sections in a single direction and at a single angle. In actual construction scenarios, building structures are complex and diverse, and it is often necessary to install and splice horizontal I-shaped steel sections that are tilted or facing different directions, but the existing devices cannot meet this demand. When encountering such situations, it is often necessary to re-weld and install, or even replace other suitable installation structures, which not only increases the construction difficulty and cost, but also extends the construction period and seriously affects the construction efficiency. With the increasing diversification and complexity of building design, higher requirements are placed on the flexible adjustment and adaptability of prefabricated steel structures, and the adaptability performance of the existing device during overall use is poor, so it needs to be improved and designed.

[0003] To this end, we propose an assembly module and construction method for prefabricated buildings to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: Firstly, the present invention can effectively improve the adaptability of the device by providing an annular moving mechanism. In actual operation, the screw rod at the bottom of the fixed plate is adjusted to disengage its end from the limiting hole, thereby releasing the limit between the sliding block and the annular rail, and the sliding block can be flexibly adjusted to slide in the vertical rail, thereby adjusting the height of the assembly device to meet the needs of different construction scenarios.

Secondly, in the present invention, the device is provided with a limiting mechanism, so that when in use, the adjustable shaft can be rotated on the concave frame, thereby driving the concave hinge seat to rotate, thereby realizing the rotation adjustment of the mounting mechanism. At the same time, by adjusting the adjusting wheel in the concave hinge seat, the inclination angle of the mounting mechanism can be accurately adjusted. After the adjustment is completed, the adjusting handle is twisted to push the first screw to rotate, drive the base block to slide, drive the connecting arm to insert the clamping arm into the clamping slot to fix the shaft, and then fix the concave hinge seat. After the adjusting wheel is adjusted, the limiting screw is twisted to connect with the threaded hole of the adjusting wheel for fixing. This allows the device to flexibly adjust the inclination angle and direction of the mounting mechanism and can be quickly fixed, thereby improving the adaptability. Third, in the present invention, the device adopts a card group, so that when the slider is adjusted and moved on the outside of the ring rail during use, the position and direction of the installation mechanism can be flexibly changed. Combined with the angle adjustment mechanism, the splicing parameters of the transverse steel beam can be more flexibly adjusted to meet the installation requirements of different prefabricated buildings. After the device is adjusted, the adjustment handle is twisted, and the screw drives the base block to slide. After a series of transmissions, the limit arm is inserted into the limit groove to assist in the installation of the limit mechanism, thereby improving the convenience of use. After the adjustment and fixation are completed, the locking screw is inserted into the card hole to fix the first screw rod, and the second screw rod and the card arm are fixed synchronously to ensure the stability of the device and realize flexible and stable adjustment of the installation mechanism. Fourthly, in the present invention, by setting up an installation mechanism, during use, the transverse steel beam can be preliminarily installed by using the installation groove and the installation block to fit together, and then the fixing screw can be twisted to insert the positioning hole to assist in fixing the installation block, which is convenient for the installation of the transverse steel beam. When disassembly or adjustment is required, the operation is also very simple. Twist the locking screw out of the card hole, adjust the adjustment handle, and drive the first screw to move the base block outward, so as to quickly release the limit of the rotating shaft and the slider. The rotation of the adjustment wheel can also be adjusted by loosening the limit screw. The whole process facilitates flexible adjustment and installation, effectively improves construction efficiency, and further enhances the adaptability of the device in actual use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-8In an embodiment of the present invention, an assembly module for use in prefabricated buildings includes a support steel column 1, wherein vertical rails 2 are fixedly connected to the outer surface of the support steel column 1 at equal intervals and arranged in a ring shape, an assembly device 3 is movably mounted on the outer surface of the support steel column 1 via the vertical rail 2, and a transverse steel beam 4 is mounted on the outer side of the assembly device 3; The assembling device 3 includes an annular moving mechanism 31, which is movably mounted on the outer side of the vertical rail 2. Bearing assemblies 32 are evenly spaced apart on the outer side of the annular moving mechanism 31. A limiting mechanism 33 is fixedly mounted on the outer side of the bearing assembly 32. An angle adjustment mechanism 34 is also mounted on the outer side of the bearing assembly 32. The angle adjustment mechanism 34 is disposed on the outer side of the limiting mechanism 33. A mounting mechanism 35 is fixedly mounted on the outer side of the angle adjustment mechanism 34. The annular moving mechanism 31 includes a sliding block 311, which is slidably connected to the inside of the vertical rail 2, and an annular rail 312 is fixedly installed on the outside of the sliding block 311, and a fixing plate 313 is fixedly installed on the bottom of the annular rail 312 in an annular arrangement at equal intervals. The lower end of the fixing plate 313 is threadedly connected to a mounting screw 314, and the mounting screw 314 is set as a hand-tightened screw. Limiting holes 315 are arranged linearly at equal intervals on the inner side of the vertical rail 2, and the ends of the mounting screws 314 are inserted into the inside of the limiting holes 315. The bearing assembly 32 is arranged on the outside of the annular rail 312. During the use of this device, the supporting steel column 1 serves as the basic supporting structure, and the vertical rails 2 arranged in an annular arrangement at equal intervals on its outer surface provide a movable track for the annular rail 312. The annular rail 312 can move along the vertical rail 2, and the assembling device 3 with equal intervals and sliding connection inside can flexibly adjust its position accordingly, adjusting the annular movement in the mechanism. The mechanism 31 is installed on the outside of the vertical rail 2. It can drive the load-bearing components 32 installed at equal intervals on the outside to move, thereby changing the overall position of the assembly device 3. The load-bearing components 32 not only provide support for the limiting mechanism 33, the angle adjustment mechanism 34 and the installation mechanism 35, but also are connected with the limiting mechanism 33 to ensure the stability of the structure. The limiting mechanism 33 can assist in fixing the angle adjustment mechanism 34 and the load-bearing components 32 to ensure the precise operation of each mechanism. The angle adjustment mechanism 34 is connected with the limiting mechanism 33 and can be adjusted at an angle under its constraint. By adjusting the angle, the installation mechanism 35 can adapt to the installation requirements of the transverse steel beam 4 in different directions. The installation mechanism 35 is fixed on the outside of the angle adjustment mechanism 34 and is used to install the transverse steel beam 4. The construction personnel change the angle of the installation mechanism 35 by operating the angle adjustment mechanism 34, and accurately install the transverse steel beam 4 in the appropriate position, thereby realizing the rapid assembly of the prefabricated building.

[0020] See also Figure 4-Figure 8The cam 338 is a key component of the cam 339, which is a key component of the cam 339, and a key component of the cam 339. The cam 339 is a key component of the cam 339, and a key component of the cam 339 is a key component of the cam 339. The screw 338 is set to a hand-tightened screw, and the guide rail 331 is evenly spaced and annularly arranged with card holes 336 on both sides. The end of the locking screw 338 is inserted into the inside of the card hole 336, and the guide rail 331 is fixedly installed with a card group 339 on one side near the annular rail 312 at both ends. The card group 339 and the annular rail 312 are clamped together, and the limiting screw 346 is threadedly connected to the upper and lower ends of the outer side of the concave hinge seat 343. Threaded holes are evenly spaced on both sides of the outer surface of the adjusting wheel 344. The end of the limiting screw 346 passes through the concave hinge seat 343 and is threadedly connected with the threaded holes on the outer surface of the adjusting wheel 344. In the limiting mechanism 33 of this prefabricated building assembly module, each component cooperates closely to achieve precise limiting and firm fixation of the angle adjustment mechanism 34. When it is necessary to adjust the installation When the angle of the mounting mechanism 35 is fixed, the adjusting handle 337 is rotated, and the adjusting handle 337 drives the first screw rod 332 to rotate in the guide rail 331. Since the threads at both ends of the first screw rod 332 rotate in opposite directions, its rotation will cause the base block 333 threadedly connected at both ends to move toward or away from each other along the guide rail 331. The connecting arm 334 on the outside of the base block 333 moves with the base block 333, thereby driving the inner clamping arm 335 to move. When the clamping arm 335 moves to align with the clamping groove 345 on the outer surface of the rotating shaft 342, it is inserted into the clamping groove 345 to achieve preliminary limitation of the rotating shaft 342, thereby fixing the angle of the concave hinge seat 343 and the mounting mechanism 35. After the adjustment is completed, the locking screw 338 is rotated to insert its end into the clamping screws arranged in a ring on both sides of the guide rail 331. The first screw rod 332 is restricted in rotation in the hole 336, ensuring that the clamping arm 335 is continuously and stably clamped in the clamping groove 345, further enhancing the limiting effect, and the locking screw 338 is designed to be hand-tightened, which is convenient for the operator to directly operate manually. In addition, the clamping group 339 fixedly installed at both ends of the guide rail 331 near the side of the annular rail 312 is clamped with the annular rail 312, increasing the stability of the connection between the entire limiting mechanism 33 and the annular rail 312. As for the fixing of the adjusting wheel 344, the limiting screw 346 is threadedly connected at the upper and lower ends of the outer side of the concave hinge seat 343, and the end of the limiting screw 346 passes through the concave hinge seat 343 and is threadedly connected to the threaded holes on both sides of the outer surface of the adjusting wheel 344, so as to achieve a stable limit to the adjusting wheel 344 and prevent it from rotating accidentally.Ensure the accuracy and stability of the entire installation angle.

[0021] See also Figure 1-Figure 3 , a mounting plate 5 is fixedly installed at the bottom of the supporting steel column 1, and mounting holes 6 are arranged in a ring at equal intervals on the outside of the mounting plate 5. The mounting holes 6 are set as countersunk holes. In the construction process of the prefabricated building, the supporting steel column 1 is the key supporting component of the entire assembly module. The mounting plate 5 fixedly installed at the bottom of the supporting steel column 1, and the mounting holes 6 arranged in a ring at equal intervals on the outside play an important role. These mounting holes 6 are set as countersunk holes. During installation, suitable bolts or screws can be passed through the countersunk holes to connect with the basic structure of the building, such as ground embedded parts, other supporting structures, etc. The design allows the heads of the bolts or screws to sink into the holes and not protrude from the surface of the mounting plate 5. This not only ensures the tightness and flatness of the connection between the mounting plate 5 and the underlying structure, but also avoids potential safety hazards caused by the protrusion of the bolt or screw heads, as well as interference with subsequent construction or use. Through the cooperation of these mounting holes 6 and the corresponding connecting parts, the supporting steel column 1 can be firmly installed in the designated position, providing a stable and reliable support foundation for the assembly of the entire prefabricated building, ensuring the smooth installation and use of subsequent components such as the ring rail 312, the assembly device 3 and the transverse steel beam 4.

[0022] See also Figure 1-Figure 5The top of the mounting plate 5 is equidistantly arranged in a ring and fixedly connected with a supporting plate 7. The inner side of the supporting plate 7 is fixedly connected to the lower end of the outer surface of the supporting steel beam. The supporting plate 7 is an isosceles trapezoidal arrangement. The external edges and corners of the mounting plate 5, the supporting plate 7, the supporting steel column 1 and the transverse steel beam 4 are all arranged in an arc shape. The transverse steel beam 4 is installed on the outer side of the angle adjustment mechanism 34 through the mounting mechanism 35. The internal top view shape of the vertical rail 2 is a convex shape, and the top view shape of the sliding block 311 is also a convex shape. In the assembly module of this prefabricated building, various components work together to ensure the stability and function of the overall structure. The supporting plates 7 are equidistantly arranged in a ring at regular intervals on the top of the mounting plate 5, and the inner side is fixedly connected to the lower end of the outer surface of the supporting steel beam. The isosceles trapezoidal supporting plate 7 provides additional support and stability for the supporting steel column 1, disperses the pressure borne by the supporting steel column 1, and enhances the stability and function of the mounting plate 5. The stability of the connection part of the mounting plate 5, the external corners of the mounting plate 5, the supporting plate 7, the supporting steel column 1 and the transverse steel beam 4 are set to be arc-shaped. This design can effectively avoid personal injury and damage to other components caused by sharp corners during construction and use, while reducing stress concentration and improving the durability of the structure. The transverse steel beam 4 is installed on the outside of the angle adjustment mechanism 34 through the mounting mechanism 35. The angle adjustment mechanism 34 can flexibly adjust the installation angle of the transverse steel beam 4 to meet the needs of different building structures. The top view of the interior of the vertical rail 2 and the sliding block 311 are both convex. This special shape design can effectively prevent the sliding block 311 from shifting or falling off when sliding inside the vertical rail 2, ensuring the stability and accuracy of the movement of the ring rail 312 and the assembly device 3 installed thereon, and ensuring the reliable operation of the entire assembly module during installation and use.

[0023] See also Figure 4-Figure 7The bearing assembly 32 includes a slider 321, which is slidably connected to the inside of the annular rail 312. A concave covering seat 322 is fixedly installed on the outside of the slider 321. The concave covering seat 322 is slidably connected to the outside of the annular rail 312. The angle adjustment mechanism 34 and the limiting mechanism 33 are both installed on the outside of the concave covering seat 322.

The end of the limiting mechanism 33 is engaged with the card groove 345. In this assembled building assembly module, the bearing component 32 serves as the key connection and transmission part, and works in conjunction with the angle adjustment mechanism 34 and the limiting mechanism 33. The slider 321 slides inside the annular rail 312 The concave covering seat 322 fixed on the outside of the circular rail 312 not only wraps around the outside of the circular rail 312 to play a certain protective role, but also provides an installation basis for the angle adjustment mechanism 34 and the limit mechanism 33. When the installation angle of the transverse steel beam 4 needs to be adjusted, the angle adjustment mechanism 34 starts to work, and the rotating shaft 342 on the concave frame 341 is rotated. The rotating shaft 342 drives the concave hinge seat 343 at the outer end to rotate, thereby preliminarily changing the angle of the installation mechanism 35. Further rotating the concave hinge seat 342 will change the angle of the installation mechanism 35. The adjusting wheel 344 on the inner side of the shaped hinge seat 343 drives the mounting mechanism 35 fixedly connected on the outside to further rotate, thereby achieving fine adjustment of the mounting angle. The limiting mechanism 33 plays an important positioning and fixing role in the adjustment process. Its end is engaged with the annular slot 345 arranged on the outer surface of the rotating shaft 342. When the angle adjustment is completed, the rotating shaft 342 is locked in the corresponding position to prevent it from rotating at will, thereby ensuring the stability of the angle of the mounting mechanism 35, and thus ensuring the accuracy and stability of the installation of the transverse steel beam 4.

[0024] See also Figure 6-Figure 7The mounting mechanism 35 comprises a card seat 351, which is fixedly connected to the outer side of the adjusting wheel 344.

The fixing screws 354 are also set as hand-tightening screws. The transverse steel beam 4 is fixedly connected to the outer side of the mounting block 353. When the transverse steel beam 4 needs to be installed during the use of this device, the mounting block 353 is first inserted into the mounting groove 352 on the outer side of the card seat 351. Since the two sides of the card seat 351 The middle part of the side is threadedly connected to a hand-tightened fixing screw 354. The operator manually twists the fixing screw 354 so that its end passes through the base 351 and moves toward the mounting block 353. When the end of the fixing screw 354 is inserted into the positioning holes 355 on both sides of the mounting block 353, the mounting block 353 is fixed in the mounting groove 352. Because the transverse steel beam 4 is fixedly connected to the outer side of the mounting block 353, the transverse steel beam 4 is also installed and firmly fixed on the base 351. To remove or adjust the transverse steel beam 4, you only need to manually twist the fixing screw 354 in the opposite direction to allow its end to withdraw from the positioning hole 355, release the fixation of the mounting block 353, and then you can remove the mounting block 353 from the mounting groove 352, thereby realizing the removal or position adjustment of the transverse steel beam 4.

The side rail 3391 is fixedly connected to the two ends of the side of the guide rail 331 close to the annular rail 312. The internal rotation of the side rail 3391 is connected to the second screw rod 3394. The limiting grooves 3393 are arranged in a ring shape with equal spacing and are opened at the top and bottom of the annular rail 312. The two ends of the second screw rod 3394 are screwed in opposite directions. The side rail 3391 is provided with a reserved groove 3395 on the side close to the guide rail 331.

The end of the movable block 3398 is fixedly installed with a limiting arm 3399. The end of the limiting arm 3399 is inserted into the inner part of the limiting groove 3393. During use, when the slider 321 needs to be positioned and fixed, the fixed arm 3392 drives the rack 3397 to drive the gear 3396 to rotate, which can drive the second screw rod 3394 to rotate. When the second screw rod 3394 is rotated, since the threads at both ends of the second screw rod 3394 rotate in opposite directions, its rotation will drive the movable block 3398 connected by the threads at both ends to move in the opposite directions along the second screw rod 3394. When the movable block 3398 moves, it drives the limit arm 3399 to move synchronously. At this time, the limit arm 3399 can be adjusted. 99 moves. When the movable block 3398 drives the limiting arm 3399 to move to align with the limiting grooves 3393 that are evenly spaced at the top and bottom of the annular rail 312, the end of the limiting arm 3399 is inserted into the limiting groove 3393 to achieve positioning and fixation of the connecting arm 334 and related components; if the position of the components needs to be adjusted, the second screw rod 3394 is rotated in the reverse direction to pull the limiting arm 3399 out of the limiting groove 3393. After readjusting the position, the second screw rod 3394 is rotated again to complete the positioning and fixation of the new position.

[0026] A construction method for prefabricated buildings, comprising the following steps: Step 1: During construction, the support steel column 1 is preliminarily installed through the mounting holes 6 on the mounting plate 5 with bolts. After installation, the mounting screw 314 at the bottom of the fixing plate 313 is adjusted to move outward so that the end of the mounting screw 314 is disengaged from the limiting hole 315, thereby releasing the limiting relationship between the sliding block 311 and the outer ring rail 312; Step 2: Adjust the sliding block 311 to slide inside the vertical rail 2, and adjust the height of the assembly device 3 according to construction requirements. If necessary, multiple sets of assembly devices 3 can be installed on the outer surface of the supporting steel column 1; Step 3: After the height adjustment is completed, the slider 321 inside the annular rail 312 is adjusted to slide, driving the angle adjustment mechanism 34 and the mounting mechanism 35 to perform displacement adjustment to determine the direction of the mounting mechanism 35; Step 4: Adjust the rotation shaft 342 on the concave frame 341 to rotate the concave hinge seat 343, thereby adjusting the rotation of the mounting mechanism 35; then adjust the adjustment wheel 344 inside the concave hinge seat 343 to rotate and accurately adjust the tilt angle of the mounting mechanism 35; Step 5: After the adjustment is completed, twist the adjustment handle 337 to push the first screw 332 to rotate in the guide rail 331, driving the base block 333 to slide, driving the connecting arm 334 to insert the clamping arm 335 into the clamping groove 345 to fix the rotating shaft 342, thereby fixing the concave hinge seat 343. Twist the limit screw 346 to connect it with the threaded hole on the outer surface of the adjustment wheel 344, and fix the adjustment wheel 344 to complete the adjustment and fixation of the entire device. Step 6: When installing the transverse steel beam 4, insert the mounting block 353 into the mounting groove 352, twist the fixing screw 354 and insert it into the positioning hole 355 to assist in fixing the transverse steel beam 4; when disassembly or adjustment is required, twist the locking screw 338 to disengage the locking hole 336, and then adjust the adjustment handle 337 to drive the first screw 332 to move the base block 333 outward, so as to release the limit of the rotating shaft 342 and the slider 321; loosen the limit screw 346, and adjust the adjustment wheel 344 to rotate, and then adjust or disassemble again.

[0027] The working principle of the present invention is as follows: during the application of the present invention, the setting of its annular moving mechanism 31 can further improve the adaptability of the device during use. In actual operation, the user can adjust the mounting screw 314 at the bottom of the fixing plate 313. When the mounting screw 314 is twisted to move it outward, the end of the mounting screw 314 will gradually disengage from the limiting hole 315, thereby separating the mounting screw 314 and the limiting hole 315 from each other. This separation operation releases the limiting relationship between the sliding block 311 and the outer annular rail 312. At this time, the user can freely adjust the sliding block 311 to slide inside the vertical rail 2. In this way, the height of the assembling device 3 can be flexibly adjusted to meet the needs of different construction scenarios. At the same time, it is also convenient to install multiple sets of assembling devices 3, which can improve the adaptability of the overall device during use. Moreover, in practical applications, multiple sets of assembling devices 3 can be installed on the outer surface of the supporting steel column 1 according to specific construction requirements. When the height adjustment of the assembling device 3 is completed, the sliding block 321 located inside the annular rail 312 can be further adjusted to slide, thereby driving the angle adjustment mechanism 34 and the mounting mechanism 35 on the outer side thereof to perform flexible displacement adjustment. In this way, the height and direction of each mounting mechanism 35 can be adjusted more flexibly. This flexible adjustment method greatly improves the convenience of the device during use, enables the device to have better adaptability, and can meet diverse construction requirements. The present invention provides a limit mechanism 33 so that a quick limit installation can be performed during use. During operation and adjustment, by adjusting the rotating shaft 342 on the concave frame 341, the rotation of the rotating shaft 342 will drive the concave hinge seat 343 to rotate together, thereby realizing the rotation adjustment of the mounting mechanism 35. On this basis, the adjusting wheel 344 inside the concave hinge seat 343 is adjusted to rotate, and the rotation of the adjusting wheel 344 can further drive the mounting mechanism 35 outside thereof to rotate. By adjusting the rotation angle of the adjusting wheel 344, the inclination angle of the mounting mechanism 35 can be precisely adjusted. The rotation of the adjusting rotating shaft 342 can further adjust the rotation of the adjusting wheel 344 and the mounting mechanism 35 outside thereof. At the same time, adjusting the rotation direction of the concave hinge seat 343 can change the inclination direction of the mounting mechanism 35 when the adjusting wheel 344 rotates. Through these operations, the present device can flexibly adjust the inclination angle and direction of the mounting mechanism 35, fully meeting the assembly and combination requirements of the transverse steel beam 4 in different directions and angles, and significantly improving the adaptability of the device. After the device is adjusted, in order to ensure the stability of the mounting mechanism 35, the adjusting handle 337 can be twisted to rotate it. The rotation of the adjusting handle 337 will push the first screw rod 332 to rotate inside the guide rail 331. The rotation of the first screw rod 332 drives the base block 333 to slide inside the guide rail 331. As the base block 333 slides, the connecting arm 334 on the outside thereof will be pushed to move. The movement of the connecting arm 334 drives the clamping arm 335, so that the clamping arm 335 is inserted into the inner side of the clamping slot 345, thereby assisting the rotation shaft 342. After the rotating shaft 342 is fixed, it can further assist in fixing the concave hinge seat 343. After the adjustment wheel 344 is rotated and adjusted, it is only necessary to twist the limiting screw 346 so that it is threadedly connected with the threaded hole on the outer surface of the adjustment wheel 344 to fix the adjustment wheel 344. This series of operations makes it easy to flexibly adjust the inclination angle and direction of the mounting mechanism 35 during use, and can quickly achieve fixation, further improving the adaptability of the device during actual use. The present invention adopts the arrangement of the card group 339 so that when the device is in use, when the slider 321 is adjusted and moved outside the annular rail 312, the position and orientation of the installation mechanism 35 can be flexibly adjusted. Combined with the design of the angle adjustment mechanism 34, the device can more flexibly adjust the splicing installation angle, direction and position of the transverse steel beam 4, better meeting the combined installation requirements of different prefabricated buildings. After the device is adjusted, when the adjustment handle 337 is twisted for further adjustment, the screw drives the base block 333 to slide, and the base block 333 drives the connecting arm 334, and the connecting arm 334 pushes the fixed arm 3392 thereon to move. The movement of the fixed arm 3392 causes the rack 3397 at its outer end to produce a lateral displacement. Since the rack 3397 and the gear 3396 are meshed with each other, the movement of the rack 3397 drives the gear 3396 to rotate, and the rotation of the gear 3396 drives the second screw rod 3394 to rotate. The rotation of the second screw rod 3394 drives the movable block 3398 to slide inside the side rail 3391. The sliding of the movable block 3398 drives the limiting arm 3399 to move inward, so that the limiting arm 3399 is inserted into the limiting groove 3393. The mutual engagement and limiting of the limiting arm 3399 and the limiting groove 3393 realizes the auxiliary installation of the limiting mechanism 33, which effectively improves the convenience of the device in actual use. After the adjustment and fixation is completed, it is only necessary to twist the locking screw 338 and insert it into the clamping hole 336 so that the locking screw 338 and the clamping hole 336 are mutually restricted, and the first screw rod 332 can be locked and fixed. After the first screw rod 332 is fixed, the second screw rod 3394 and the clamping arm 335 are also fixed synchronously, which makes the device as a whole have strong stability and can flexibly and firmly adjust the position and angle of the mounting mechanism 35; When installing the transverse steel beam 4, the mounting mechanism 35 of the present device adopts the method of mutually clamping the mounting groove 352 and the mounting block 353. By twisting the fixing screw 354 and inserting it into the inner side of the positioning hole 355, auxiliary fixation of the mounting block 353 is achieved, which facilitates the installation operation of the transverse steel beam 4. When the device needs to be disassembled or adjusted, it is only necessary to twist the locking screw 338 to disengage it from the inner side of the clamping hole 336, and then adjust the adjustment handle 337 to drive the first screw rod 332 to drive the base block 333 to move outward, so as to quickly release the limit of the rotating shaft 342 and the slider 321, which is convenient for adjustment again. By loosening the limit screw 346, the rotation of the adjusting wheel 344 can also be adjusted. It can be seen that the overall device is easy to adjust and install flexibly, which further improves its adaptability during actual use.
