Description

Technical Field

[0001] This invention relates to the field of building beam and column installation technology, and in particular to an auxiliary device for installing prefabricated steel structure beams and columns. Background Technology

[0002] In the construction of prefabricated buildings, the installation of steel structure beams and columns is one of the key steps. Traditional beam and column installation methods mainly rely on large lifting equipment, such as tower cranes. After the columns are installed on the ground base, the beams are horizontally hoisted to a predetermined height position on the side of the columns by the lifting equipment, and then the beams are installed with the columns as a whole by means of bolts or welding.

[0003] However, the use of lifting equipment is problematic. Firstly, the rental cost is relatively high, and the use of lifting equipment is inconvenient in some confined construction sites. Secondly, when lifting equipment is used to lift beams, the stability of the beams is poor. After the beams are lifted to the predetermined height, they still need to be manually adjusted to the correct installation position, which affects the installation efficiency of the beams and columns. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for the installation of steel structure beams and columns in prefabricated buildings, so as to solve the technical problems existing in the prior art.

The lifting frame consists of two sets, which are fitted onto the outside of the column and distributed vertically. The upper lifting frame is used to support the crossbeam. The drive component is mounted on the lower lifting frame and is used to intermittently drive the upper lifting frame to move upward. One end of the elastic lifting component is connected to one set of the lifting frames, and the other end is connected to another set of lifting frames. The locking assembly is provided in two sets, and the two sets of locking assemblies are respectively installed on the two sets of lifting frames. As the drive component moves the upper lifting frame upward, the lower locking component locks the lower lifting frame outside the column to provide stable support for the drive component. After the upper lifting frame moves up to a predetermined height, the upper locking component locks the upper lifting frame to the outside of the column, and the elastic lifting component pulls up the lower lifting frame and the drive component.

The support is fixedly mounted on the outer wall of the lower lifting frame, the slider is fixedly mounted on the outer wall of the upper lifting frame, one end of the guide rod is fixedly connected to the support, and the other end passes through the slider and is movably engaged with the slider. One end of the second elastic element is connected to the support, and the other end is connected to the slider.

[0007] As a further improvement of the present invention: the inner wall of the lifting frame is provided with a groove. The locking assembly includes an L-shaped connecting rod, a first elastic element, and a top support plate. The top support plate is movably disposed inside the groove. One end of the L-shaped connecting rod extends into the groove and is fixedly connected to the top support plate. The other end passes through the side wall of the lifting frame and extends to one side of the eccentric disk. An arc-shaped protrusion is fixedly disposed on the edge of the side wall of the eccentric disk.

[0008] As a further improvement of the present invention: a sleeve is rotatably sleeved on the rod body located on the side of the eccentric disk of the L-shaped connecting rod.

[0009] As a further improvement of the present invention: the first elastic element and the second elastic element are springs or metal sheets.

[0010] As a further improvement of the present invention: a notch is provided on one side of the lifting frame for the column to enter and exit, a baffle is hinged in the notch, and ear plates are fixedly provided on both the baffle and the side wall of the lifting frame, and the two sets of ear plates are connected by bolts.

[0011] As a further improvement of the present invention: a U-shaped seat is fixedly provided on the outer wall of the upper lifting frame.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects: Compared with the prior art, the embodiments of the present invention, through the cooperation of the driving component, the elastic lifting component and the locking component, can drive the two sets of lifting frames to move alternately upward along the outside of the column, thereby stably lifting the crossbeam to the predetermined height, thus realizing convenient and efficient installation between the crossbeam and the column.

[0018] The present invention will be further explained below with reference to specific embodiments.

[0019] Please see Figure 1 and Figure 2 This embodiment provides an auxiliary device for installing steel structure beams and columns in prefabricated buildings, including a lifting frame 10, a locking component 20, a driving component 30, and an elastic lifting component 40. The lifting frame 10 has two sets, which are sleeved on the outside of the column and distributed vertically. The upper lifting frame 10 is used to support the crossbeam. The driving component 30 is installed on the lower lifting frame 10 and is used to intermittently drive the upper lifting frame 10 upwards. One end of the elastic lifting component 40 is connected to one set of lifting frames 10, and the other end is connected to the other set of lifting frames 10. The lifting frame 10 is connected, and the locking component 20 is provided in two sets. The two sets of locking components 20 are respectively installed on the two sets of lifting frames 10. When the driving component 30 drives the upper lifting frame 10 to move upward, the lower locking component 20 locks the lower lifting frame 10 to the outside of the column to provide stable support for the driving component 30. After the upper lifting frame 10 moves upward to a predetermined height, the upper locking component 20 locks the upper lifting frame 10 to the outside of the column. The elastic lifting component 40 lifts the lower lifting frame 10 and the driving component 30.

[0020] When the crossbeam needs to be installed on the side wall of the column, two sets of lifting frames 10 can be fitted onto the outside of the column, with the two sets of lifting frames 10 arranged vertically. Then, the crossbeam is placed on the upper lifting frame 10, and the drive assembly 30 operates to move the upper lifting frame 10 upward a predetermined distance along the outside of the column. During this process, the locking assembly 20 on the lower lifting frame 10 locks the lower lifting frame 10 to the outside of the column to provide stable support for the drive assembly 30. After the upper lifting frame 10 has moved upward a predetermined distance, the locking assembly 20 on the upper lifting frame 10 locks the upper lifting frame 10 to the outside of the column. Then, the elastic lifting assembly 40 pulls the lower lifting frame 10 and the drive assembly. The upper lifting frame 10 moves upward a predetermined distance along the outside of the column. During this process, the locking component 20 on the upper lifting frame 10 locks the upper lifting frame 10 to the outside of the column, so that the elastic lifting component 40 can smoothly lift the lower lifting frame 10 and the drive component 30. Then the drive component 30 drives the upper lifting frame 10 to move upward a predetermined distance along the outside of the column again, and the lower locking component 20 locks the lower lifting frame 10 to the outside of the column again. This cycle repeats, so that the two sets of lifting frames 10 can move upward alternately along the outside of the column. During the upward movement, the upper lifting frame 10 drives the crossbeam to move upward along the side of the column. When the crossbeam moves to the predetermined height position, the staff can install the crossbeam on the side wall of the column.

[0021] Please see Figure 1 , Figure 2 as well as Figure 4 In one embodiment, an extension block 102 is fixedly disposed on the outer wall of the upper lifting frame 10. The drive assembly 30 includes an eccentric disk 301, a motor 303, and a support plate 304. The support plate 304 is fixedly installed on the outer wall of the lower lifting frame 10. The motor 303 is fixedly disposed on the outside of the support plate 304. The eccentric disk 301 is installed on the output end of the motor 303. The elastic lifting assembly 40 includes a guide rod 401, a slider 402, a second elastic element 403, and a support 404. The support 404 is fixedly disposed on the outer wall of the lower lifting frame 10. The slider 402 is fixedly disposed on the outer wall of the upper lifting frame 10. One end of the guide rod 401 is fixedly connected to the support 404, and the other end passes through the slider 402 and is movably engaged with the slider 402. One end of the second elastic element 403 is connected to the support 404, and the other end is connected to the slider 402.

[0022] After the two sets of lifting frames 10 are fitted onto the outside of the column, the crossbeam is placed on the upper lifting frame 10. Then, the motor 303 is started, which drives the eccentric disk 301 to rotate. When the eccentric disk 301 rotates, its circumferential sidewall acts on the bottom of the extension block 102, thereby pushing the upper lifting frame 10, causing the upper lifting frame 10 to move upward along the outside of the column. At this time, the upper lifting frame 10 drives the crossbeam to move upward synchronously, and the slider 402 slides upward adaptively along the outside of the guide rod 401. The second elastic element 403 is stretched, and the locking component 20 on the lower lifting frame 10 locks the lower lifting frame 10 to the outside of the column, so as to provide stable support for the bracket plate 304, the motor 303, and the eccentric disk 301. When the upper lifting frame 10 moves upward a predetermined distance, the eccentric disk 301 separates from the extension block 102, and the locking component 20 on the upper lifting frame 10 will... The upper lifting frame 10 is locked to the outside of the column. Then, the locking component 20 on the lower lifting frame 10 releases the locking state of the lifting frame 10. The second elastic element 403 pulls the support 404, thereby causing the lower lifting frame 10 to move upward a predetermined distance along the outside of the column. At this time, the guide rod 401 moves upward relative to the slider 402, and the second elastic element 403 retracts and resets. Then, the locking component 20 on the lower lifting frame 10 locks the lower lifting frame 10 again, and the locking component 20 on the upper lifting frame 10 releases the locking state of the lifting frame 10. The circumferential sidewall of the eccentric disk 301 acts on the bottom of the extension block 102 again, thereby pushing the upper lifting frame 10 and the crossbeam to move upward a predetermined distance again. This cycle repeats, and the crossbeam can be lifted to a predetermined height position on the side of the column to facilitate the installation between the crossbeam and the column.

[0023] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In one embodiment, the inner wall of the lifting frame 10 is provided with a groove 106, and the locking component 20 includes an L-shaped connecting rod 201, a first elastic element 203 and a top support plate 204. The top support plate 204 is movably disposed inside the groove 106. One end of the L-shaped connecting rod 201 extends into the groove 106 and is fixedly connected to the top support plate 204, and the other end passes through the side wall of the lifting frame 10 and extends to one side of the eccentric disk 301. An arc-shaped protrusion 302 is fixedly disposed on the edge of the side wall of the eccentric disk 301.

[0024] When the motor 303 drives the eccentric disk 301 to rotate, the eccentric disk 301 can drive the arc-shaped protrusion 302 to rotate synchronously. Just as the circumferential sidewall of the eccentric disk 301 is about to act on the bottom of the extension block 102, one end of the arc-shaped protrusion 302 first acts on the L-shaped connecting rod 201 on the sidewall of the upper lifting frame 10, thereby pushing the L-shaped connecting rod 201 to move outward relative to the upper lifting frame 10, and then pulling the corresponding top support plate 204 into the corresponding groove 106, so that the top support plate 204 separates from the outer wall of the column, thereby releasing the locked state of the upper lifting frame 10. Subsequently, as the eccentric disk 301 continues to rotate, the circumferential sidewall of the eccentric disk 301 acts on the extension block 102. 02. At the bottom, the upper lifting frame 10 is pushed upward a predetermined distance along the outside of the column. During this process, the top support plate 204 on the lower lifting frame 10 is supported by the corresponding first elastic element 203 and pressed against the outer wall of the column, thereby locking the lower lifting frame 10 to provide stable support for the bracket plate 304, motor 303, and eccentric disk 301. After the upper lifting frame 10 moves upward a predetermined distance, the eccentric disk 301 separates from the extension block 102, and at the same time, the arc-shaped protrusion 302 separates from the L-shaped connecting rod 201 on the upper lifting frame 10. The corresponding first elastic element 203 pushes the corresponding top support plate 204 to move inward toward the inside of the upper lifting frame 10. It acts on the outer wall of the column to lock the upper lifting frame 10. As the eccentric disk 301 continues to rotate, the arc-shaped protrusion 302 acts on the L-shaped connecting rod 201 on the lower lifting frame 10, causing the L-shaped connecting rod 201 to move outward relative to the lower lifting frame 10. This pulls the corresponding top support plate 204 into the corresponding groove 106 to release the locking state of the lower lifting frame 10. At this time, the second elastic element 403 pulls the lower lifting frame 10 upward along the outside of the column. After the lower lifting frame 10 moves upward a predetermined distance, the arc-shaped protrusion 302 separates from the L-shaped connecting rod 201 on the lower lifting frame 10, and the corresponding first elastic element 203 pushes... The corresponding top support plate 204 moves downward to the inner side of the lifting frame 10 and acts on the outer wall of the column to lock the lower lifting frame 10 again. Then, the arc-shaped protrusion 302 acts on the L-shaped connecting rod 201 on the upper lifting frame 10 again, causing the L-shaped connecting rod 201 to move outward to release the locked state of the upper lifting frame 10. Then, the circumferential side wall of the eccentric disk 301 acts on the bottom of the extension block 102 again, thereby pushing the upper lifting frame 10 to move upward again by a predetermined distance. This cycle repeats, which can realize the alternating upward movement of the two sets of lifting frames 10 along the outside of the column, thereby driving the crossbeam to automatically move upward along one side of the column to a predetermined height position, thus facilitating the installation and fixation between the crossbeam and the column.

[0025] Please see Figure 2 as well as Figure 4 In one embodiment, the L-shaped connecting rod 201 is rotatably fitted with a sleeve 202 on the rod body located on the side of the eccentric disk 301.

[0026] By setting the sleeve 202, when the arc-shaped protrusion 302 acts on the L-shaped connecting rod 201, the sleeve 202 replaces the L-shaped connecting rod 201 to contact the arc-shaped protrusion 302 and rotates adaptively relative to the L-shaped connecting rod 201, thereby reducing the frictional resistance between the L-shaped connecting rod 201 and the arc-shaped protrusion 302 and avoiding excessive wear of the arc-shaped protrusion 302 and the L-shaped connecting rod 201.

[0027] In one embodiment, the first elastic element 203 and the second elastic element 403 can be springs or metal sheets, and there is no limitation here.

[0028] Please see Figure 2 as well as Figure 3 In one embodiment, a notch is provided on one side of the lifting frame 10 for the column to enter and exit. A baffle 103 is hinged in the notch. Ear plates 104 are fixedly provided on both the baffle 103 and the side wall of the lifting frame 10. The two sets of ear plates 104 are connected by bolts 105.

[0029] Initially, the baffles 103 inside the notches on one side of the two sets of lifting frames 10 are in the open state. By fitting the two sets of lifting frames 10 onto the outside of the column through the notches, and then closing the baffles 103, the two sets of ear plates 104 are locked with bolts 105, thereby confining the baffles 103 inside the notches. At this time, the lifting frames 10 and the baffles 103 are arranged around the outside of the column, thus completing the installation operation of the lifting frames 10.

[0030] Please see Figure 2 In one embodiment, a U-shaped seat 101 is fixedly installed on the outer wall of the upper lifting frame 10. By embedding the end of the crossbeam into the U-shaped seat 101, when the two sets of lifting frames 10 move upward alternately along the outside of the column, the upper lifting frame 10 drives the crossbeam to move upward synchronously with the help of the U-shaped seat 101, thereby realizing the automatic lifting of the crossbeam.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
