[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] The embodiments of the present invention provide an adjustable pedestal system, device and construction method for assembling steel beams, which can solve the problems in related technologies such as difficulty in controlling the linear shape of steel beams, low assembly efficiency and unsuitability for large-scale prefabrication.

[0026] See also Figure 1 and Figure 2 As shown, a steel beam assembly adjustable pedestal system provided by an embodiment of the present invention may include a base 1, a steel beam 3 and an adjustment mechanism 2.

[0027] The base 1 is cast from concrete and is provided with a plurality of steel beams 3 along the length direction. The steel beams are located above the base 1 .

[0028] In this embodiment, there are at least two steel beams 3 , which are arranged in parallel and spaced apart. The tops of the steel beams 3 are used for pouring reinforced concrete panels.

[0029] The adjusting mechanism 2 is installed on the base 1 and supported on the bottom of the steel beam 3. A plurality of the adjusting mechanisms 2 are arranged at intervals along the length direction of the steel beam 3, and the top height of each adjusting mechanism 2 is adjustable.

[0030] In this embodiment, the steel beam 3 is assembled in sequence by multiple segments, and each segment is supported by an adjustment mechanism 2 at the bottom. Since the top height of the adjustment mechanism 2 is adjustable, the overall linearity of the steel beam 3 can be adjusted. Specifically, the overall transverse slope can be adjusted by adjusting the height difference between the two steel beams 3, and the overall longitudinal slope can be adjusted by adjusting the height difference between the segments of each steel beam 3. This greatly improves the assembly efficiency of the steel beam 3 and can be applied to the batch assembly construction of large steel beams 3 without being restricted by the form and size of the steel beam 3. It can also be used for concrete beam prefabrication.

[0031] The adjustment mechanism 2 may include: a fixed vertical rod 21 having a cavity inside, and a lifting rotary lock 22 installed on the upper end of the fixed vertical rod 21; a movable vertical rod 23 having a thread on the outer side, and the movable vertical rod 23 is screwed into the lifting rotary lock 22 and inserted into the cavity.

[0032] In this embodiment, the fixed vertical pole 21 is a hollow steel tube, the lifting rotary lock buckle 22 is a nut with a rotating handle, and the movable vertical pole 23 is installed on the inner side of the lifting rotary lock buckle 22, which is a solid threaded rod. The adjustment relationship between the lifting rotary lock buckle 22 and the movable vertical pole 23 is the same as the adjustment principle of the nut and bolt. When in use, lift the movable vertical pole 23 to the required height, and screw the lifting rotary lock buckle 22 to the top of the fixed vertical pole 21 to fix the height of the movable vertical pole 23. The adjustment is precise and efficient, and the safety and reliability of the steel beam 3 during assembly can be effectively guaranteed.

[0033] See also Figure 2 and Figure 3 As shown, in some embodiments, a bracket 24 may be installed at the upper end of the movable upright 23 , and a distribution beam 25 may be provided in the bracket 24 , and the distribution beam 25 extends along the width direction of the steel beam 3 .

[0034] In this embodiment, each base 1 is provided with three sets of fixed uprights 21 and movable uprights 23 at intervals. Brackets 24 are provided at the upper ends of the three movable uprights 23. The brackets 24 have a U-shaped cross-section and are used to support and secure a distribution beam 25. The bottom plates of the brackets 24 are connected to the tops of the movable uprights 23 by single-sided circumferential welding. During use, the bracket openings are adjusted to a certain angle to secure the distribution beam 25 horizontally within the brackets 24. The distribution beam 25 is preferably constructed of I-shaped steel and can be of varying sizes depending on the actual situation. The distribution beam 25 supports the steel beam 3 along its width and evenly distributes the weight of the steel beam 3 to the three movable uprights 23, ensuring the stability of the steel beam 3. The number of fixed uprights 21 and movable uprights 23 can be determined based on the actual situation.

[0035] See also Figure 2 and Figure 3 As shown, in some embodiments, a limit block 26 can be installed on the top of the distribution beam 25. The limit block 26 can move along the length direction of the distribution beam 25 and limit the position of the steel beam 3.

[0036] In this embodiment, the limit block 26 can move along the length direction of the distribution beam 25, that is, it can move along the width direction of the steel beam 3, and limit the position of each segment of the steel beam 3 in the width direction, so that the overall pre-arch of the steel beam 3 can be adjusted.

[0037] See also Figure 2 and Figure 3 As shown, in some optional embodiments, the limit block 26 extends along the length direction of the distribution beam 25, and the limit block 26 is provided with a strip hole 261 extending along its length direction, and a fastening bolt 262 is installed in the strip hole 261, and the fastening bolt 262 is used to lock the limit block 26.

[0038] In this embodiment, the axis of the fastening bolt 262 is perpendicular to the plate surface of the distribution beam 25. When the limit block 26 is moved to the desired position on the distribution beam 25, the fastening bolt 262 can be tightened to move the fastening bolt 262 downward until the lower end abuts the distribution beam 25, thereby fixing the limit block 26 in the desired position and preventing it from moving further. This makes the limit block 26 more reliable in restraining the steel beam 3. In other embodiments, the limit block 26 can also be fixed by other means, such as a clamping member, a limiter, etc.

[0039] See also Figure 2 and Figure 3 As shown, in some embodiments, the fixed pole 21 can be fixed to the base 1 by an embedded part 27, and the embedded part includes a top plate 271 and a leg 272. The top plate 271 is fixed to the lower end of the fixed pole 21, and the leg 272 is fixed to the bottom of the top plate 271.

[0040] In this embodiment, the embedded parts 27 are evenly distributed horizontally within the base 1. The fixed uprights 21 are vertically welded to the embedded parts 27 and arranged at the center of the top plate 271. They are connected to the top plate 271 using double-sided circumferential welds, making the fixed uprights 21 more stable. The upper surface of the top plate 271 is flush with the top surface of the base 1. Triangular stiffening ribs 273 are welded between the top plate 271 and the fixed uprights 21. The stiffening ribs 273 are arranged along the diagonal lines of the top plate 271 and are connected to the fixed uprights 21 and the embedded parts 27 using double-sided fillet welds, respectively, to increase the connection strength between the top plate 271 and the fixed uprights 21. The legs 272 are U-shaped and can be formed by bending steel bars. The two legs 272 are arranged parallel and spaced apart at the bottom of the top plate 271 and are connected to the top plate 271 using double-sided welds, thereby increasing the connection strength with the base 1.

[0041] See also Figure 4 As shown, further, the steel beam assembly adjustable pedestal system may further include a positioning mechanism 5 , wherein the positioning mechanism 5 includes a positioning frame 51 , and the positioning frame 51 is supported against the end of the steel beam 3 .

[0042] In this embodiment, the positioning frame 51 is triangular in shape, with one side placed on the ground and the other side resting against the end of the steel beam 3. This can position the steel beam 3 and prevent it from moving during assembly, effectively ensuring the safety and reliability of the assembly process of the steel beam 3. The positioning frame 51 is formed by connecting steel sections and can be configured in other shapes according to actual needs.

[0043] See also Figure 4 As shown, preferably, the positioning frame 51 can be connected to the adjustment mechanism 2 through a connecting member 54.

[0044] In this embodiment, the positioning frame 51 is connected to the adjustment mechanism 2, so that it can be fixed at a desired position by the adjustment mechanism 2, preventing the positioning frame 51 from moving during use, thereby further improving safety.

[0045] See also Figure 4 As shown, in some embodiments, a first positioning ring 52 can be installed on the positioning frame 51, and the first positioning ring 52 can have first positioning rods 53 on opposite sides. A second positioning ring 55 can be installed on the adjustment mechanism 2, and the second positioning ring 55 can have second positioning rods 56 on opposite sides. The first positioning rod 53 is connected to the second positioning rod 56 through the connecting member 54.

[0046] In this embodiment, the first positioning ring 52 is a square clamp, which is installed on one side of the positioning frame 51. The second positioning ring 55 is a circular clamp, which is installed on the two fixed vertical poles 21 on the outside of the adjustable pedestal device adjacent to the positioning frame 51. The connecting member 54 can be a fastener connecting rod, and the positioning frame 51 is connected to the two fixed vertical poles 21 through the connecting member 54. The three can form a triangle, thereby further ensuring the stability of the positioning frame 51 and preventing it from moving.

[0047] See also Figure 1 、 Figure 2 and Figure 3 As shown, an adjustable pedestal device for assembling steel beams may include: a base 1; an adjustment mechanism 2 mounted on the base 1 and configured to support the bottom of a steel beam 3. The adjustment mechanism 2 includes: a fixed upright 21 having a cavity therein and a lifting and rotating lock 22 mounted on the upper end of the fixed upright 21; and a movable upright 23 having a threaded outer surface. The movable upright 23 is screwed into the lifting and rotating lock 22 and inserted into the cavity. Rotating the lifting and rotating lock 22 drives the movable upright 23 to move along its axis. The adjustable pedestal device for assembling steel beams may implement any embodiment of the adjustable pedestal system for assembling steel beams.

[0049] Arrange the position of the adjustment mechanism 2 according to the overall linear shape of the steel beam 3.

[0051] The various segments of the steel beam 3 are hoisted onto the adjusting mechanism 2 and assembled and connected. Specifically, before assembling and connecting the various segments, the positioning mechanism 5 is installed and connected to the adjusting mechanism 2. After the steel main beam is assembled, the reinforced concrete panel is cast.
