[0001] This invention relates to the field of building construction technology, specifically to a construction method for a disc-lock steel pipe support frame for oversized frame beams. Background Technology

[0002] The overall design of the bottom support frame for oversized frame beams needs to meet certain strength and anti-overturning capabilities. Traditional steel pipe coupler and cup-lock type frames, while meeting these requirements, suffer from excessively dense member spacing and higher material consumption. Furthermore, when there is a height difference between the cast-in-place slabs on both sides of the frame beam, the stability of the beam side formwork decreases, leading to substandard strength, stiffness, verticality, and overall flatness. Therefore, we propose a construction method for oversized frame beams using a disc-lock type steel pipe support frame to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a construction method for a disc-lock steel pipe support frame for oversized frame beams, in order to solve the problems mentioned in the background art, such as the traditional combined steel triangular frame being unable to meet the requirements for erecting an external protective frame due to insufficient support size, and the inconvenience of the foundation construction process for the external protective frame in special locations, resulting in high construction difficulty and slow construction progress.

[0004] To achieve the above objectives, the present invention provides the following technical solution: the construction method includes the following steps:

[0005] S1: Erect the formwork for the bottom of the beam, the bottom of the slab, and the side of the beam in sequence;

[0030] S1: Erect the formwork for the bottom of the beam, the bottom of the slab, and the side of the beam in sequence;

[0033] Preferably, in S2, the arrangement of the bottom support of the oversized frame beam includes: an oversized frame beam 6, with identical secondary beam side formwork ribs 4 symmetrically arranged on both sides of the oversized frame beam 6, and identical main beam ribs 3 arranged at the ends of the two sets of secondary beam side formwork ribs 4 away from the oversized frame beam 6, tie bolts 5 fixing through the oversized frame beam 6 and the main beam ribs 3 on both sides, and a steel pipe 7 set on the side of the cast-in-place slab height and connected to the main beam side formwork rib 3 and the cast-in-place slab disc buckle frame uprights through a disc buckle device 12.

[0034] Preferably, in S3, the arrangement of the side formwork support for the oversized frame beam includes: a special diagonal support 8 for the disc-lock frame, the special diagonal support 8 for the disc-lock frame being fully distributed along the length of the frame beam, and several sets of bottom uprights 11 being set at equal intervals at the bottom of the frame beam, with uprights 10 on both sides of the beam installed between every two sets of bottom uprights 11.

[0035] The working principle and beneficial effects of the above technical solution are as follows:

[0036] This invention discloses a construction method for a disc-lock steel pipe support frame for oversized frame beams, including the sequential erection of beam bottom, slab bottom, beam side formwork and support system. The beam and slab support system adopts a disc-lock support system. When there is a height difference between the two sides of the beam, the side formwork is supported by fastening steel pipes 7 to the secondary joists 3 of the beam side formwork with fasteners. The secondary joists 3 of the beam side formwork are fastened by tie bolts 5. The secondary joists 3 of the beam side formwork are supported by connecting the beam bottom uprights 11 through the beam bottom horizontal bars 9, thereby achieving the purpose of solving the overall stability of the support system. The bottom support frame of the oversized frame beam is erected using a disc-lock steel pipe support frame system.

[0037] When arranging the bottom support of the oversized frame beam, the horizontal spacing of the bottom uprights 11 is 600mm, the longitudinal spacing of the bottom uprights 11 is 900mm, the longitudinal spacing of the uprights 10 on both sides of the beam is 900mm, the step distance of the bottom horizontal bar 9 is 1500mm, the main keel 1 inside the top support beam is φ48*3 double steel pipe, the bottom secondary keel 2 is 7 40*80 square timbers, the bottom formwork is 15mm thick multi-layer board, and the special diagonal support 8 of the disc buckle frame is fully distributed along the length of the frame beam.

[0038] When arranging the side formwork support for the oversized frame beam, the side formwork template of the oversized frame beam uses 15mm thick film-coated multi-layer board, the secondary keel 4 of the beam side formwork uses 40*40*2 square steel pipe @250mm, the main keel 3 of the beam side formwork uses φ48*3 double steel pipe @500mm, and the tie bolts 5 use φ14 bolts in total of 3. On the side of the cast-in-place slab with the height, φ48*3 steel pipe 7 is set and connected to the main keel 3 of the beam side formwork and the uprights of the cast-in-place slab disc fastener frame through disc fastener device 12.

[0039] This invention reduces the need for side support on low-span beams, reduces material usage, and meets overall stability requirements. It also minimizes disturbance to the top reinforcement of the slab, shortens the construction period, and secures the main beam joists 3 of the beam side formwork with tie bolts 5. The main beam joists 3 and the bottom uprights 11 of the beam are supported by horizontal members, thus achieving the goal of ensuring the overall stability of the support system. Furthermore, the reasonable spacing of the members reduces material usage, thereby improving construction efficiency. When there is a height difference between the cast-in-place slabs on both sides of the frame beam, the construction method of this invention can enhance the strength, rigidity, verticality, and overall flatness of the beam side formwork. Moreover, the disc fastener connection device 12 can adapt to different scenario requirements and can accommodate steel pipes 7 and main beam joists 3 at any angle, making construction convenient and highly stable.

[0040] Example 2

[0041] Based on Example 1, please refer to Figure 2-5 The disc fastener connecting device 12 includes: a disc fastener frame 13, which has a cross-shaped U-shaped groove 14 structure, and two sets of positioning bolts 15 are movably provided on the disc fastener frame 13. Threaded holes 16 are opened at the cross ends of the disc fastener frame 13.

[0042] Preferably, four sets of adjusting members 17 are respectively located at the cross ends of the disc buckle frame 13 and are detachably connected to the disc buckle frame 13.

[0043] Preferably, the adjusting component 17 includes: a U-shaped fixing frame 18 and a U-shaped connecting frame 24. The U-shaped connecting frame 24 is disposed in the U-shaped groove 14 of the disc buckle frame 13 and is detachably connected to the disc buckle frame 13. Two sets of support plates 19 are fixedly connected to the U-shaped fixing frame 18, and two sets of support plates 22 are fixedly connected to the U-shaped connecting frame 24.

[0044] Preferably, the first connecting rod 20 is rotatably connected to two sets of support plates 19, and both ends of the first connecting rod 20 extend to two sets of support plates 22 and are fixedly connected to gears 21.

[0045] Preferably, the center of the support plate 22 is a through groove structure, and the through groove includes a rotating groove 25, a limiting groove 28 and a positioning groove 29, with the rotating groove 25 and the positioning groove 29 symmetrically arranged on both sides of the limiting groove 28.

[0046] Preferably, two sets of connecting bolts 27 are symmetrically arranged on both sides of the second support plate 22 and threadedly connected to the second support plate 22. The connecting bolts 27 extend to one end of the limiting groove 28 and are fixedly connected to the limiting block 26.

[0047] Preferably, two sets of gears 23 are symmetrically fixedly connected to the outer wall of the U-shaped connecting frame 24.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When connecting multiple intersecting steel pipes 7 and beam side formwork main keel 3 and cast-in-place slab disc buckle frame uprights, if the steel pipes 7 and beam side formwork main keel 3 are perpendicular to each other, it is only necessary to align the cross-shaped U-shaped groove 14 of the disc buckle frame 13 with the steel pipes 7 and beam side formwork main keel 3 and then buckle it. In addition, the U-shaped fixing frame 18 and U-shaped connecting frame 24 in the adjusting component 17 are also buckled onto the outer wall of the steel pipes 7 and beam side formwork main keel 3. Finally, by turning the two sets of positioning bolts 15, the two sets of positioning bolts 15 are pressed tightly against the steel pipes 7 and beam side formwork main keel 3 to prevent the disc buckle frame 13 from slipping off.

[0049] If special location nodes are encountered, the steel pipe 7 and the main keel 3 of the beam side formwork need to be bent. In order to ensure the stability of the intersection structure of the steel pipe 7 and the main keel 3 of the beam side formwork, the U-shaped fixing frame 18 is manually rotated so that the support plate 19 drives the first connecting rod 20 to rotate in the rotation groove 25 until the U-shaped fixing frame 18 is adjusted to the same bending angle as the steel pipe 7 and the main keel 3 of the beam side formwork. Then, the two sets of connecting bolts 27 are tightened to move the two sets of limiting blocks 26 in a direction away from each other and clear the limiting groove 28. Then, the U-shaped fixing frame is pushed. 18. After the support plate 19 drives the first connecting rod 20 through the limiting groove 28 into the positioning groove 29, the gear 1 21 and the gear 23 mesh together. Then, the two sets of connecting bolts 27 are turned in the opposite direction to drive the two sets of limiting blocks 26 to close the limiting groove 28, preventing the first connecting rod 20 from returning to the rotating groove 25. This allows for multi-angle adjustment of the adjusting component 17, which is convenient for matching different bending angles between the steel pipe 7 and the main keel 3 of the beam side mold. The cooperation of gear 1 21 and gear 2 23 can effectively prevent the first connecting rod 20 from rotating in the positioning groove 29.

[0050] The disc fastener connection device 12 can adapt to different scenario requirements, and can be adapted to steel pipes 7 and beam side formwork main keel 3 at any angle, making construction convenient and highly stable.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
