[0029] like Figure 1 to Figure 7 As shown, the present invention discloses a construction method and a control device for a complex steel structure 4 supported by an upper support and a lower suspension, which is used to support between the upper support steel structure 4 and the lower suspension steel structure 4 to facilitate the construction of the overall steel structure 4. Figure 2 As shown, it includes three pre-support seats 1, which are distributed along the extension direction of the lower steel structure 4 beam body and are respectively arranged at both ends and the middle of the steel structure 4 beam body, as shown in FIG. Figure 3As shown, the pre-support seat 1 includes a clamping seat 11 clamped on the lower steel structure 4, and the clamping seat 11 is composed of a seat body, a stud, a clamping plate and other structures, and is clamped on the connecting rod structure on the steel structure 4. A round seat 12 is fixedly provided on the upper end of the clamping seat 11, and a round hole is opened on the round seat 12. A transverse support beam 13 for supporting the upper steel structure 4 is also fixed above the round seat 12. The transverse support beam 13 is horizontal and also includes a connecting column 2. The connecting column 2 passes through all the round seats 12 at the same time. Blocking structures can be set at both ends of the connecting column 2 to prevent the connecting column 2 from sliding and moving. The connecting column 2 is set along the extension direction of the steel structure 4, such as Figure 4 As shown, the connecting column 2 is suspended above the lower steel structure 4 under the support of the pre-support seat 1, and the upper steel structure 4 can be pre-installed under the support of the cross support beam 13. Figure 5 and Figure 6 As shown, it also includes a plurality of main support parts 3, and the main support part 3 includes a connecting beam 31. One end of the connecting beam 31 is provided with a U-shaped buckle 32 buckled on the connecting column 2 from top to bottom. The U-shaped buckle 32 can be provided with a clamp to prevent the U-shaped buckle 32 from falling off the connecting column 2. The other end of the connecting beam 31 extends to the upper and lower sides respectively to be provided with adjustment columns 33, and the adjustment columns 33 include a bottom column 331 and a top column 332. The top column 332 is coaxially threadedly connected to the bottom column 331, and the top column 332 is respectively against the surfaces of the upper and lower steel structures 4. The length of the telescopic adjustment column 33 can be used to support the pre-supported upper steel structure 4 and fine-tune the vertical position.

[0030] This regulating device, by setting a pre-support seat 1, pre-supports the upper steel structure 4 that needs to be installed above the suspension of the lower steel structure 4, and then sets the main support part 3, which is clamped along the connecting column 2 in sequence and supported between the upper steel structure 4 and the lower steel structure 4, and by adjusting the adjusting column 33 extending up and down, the adjusting column 33 can be vertically supported between the upper and lower steel structures 4, and as the number and distribution of the main support parts 3 increase, the upper steel structure 4 is gradually propped up and leaves the pre-support seat 1. With the adjustment of each adjusting column 33, the vertical position and horizontality of the upper steel structure 4 can be adjusted. This structure can simply and quickly place and support the upper steel structure 4 in place by setting the pre-support seat 1 and the main support part 3. The position of the main support part 3 can be adjusted according to the position of the supported point of the upper steel structure 4. It has good flexibility and strong support. After disassembly, the various components are connected to facilitate unloading and avoid the separation and falling of components.

[0031] In a further solution, Figure 3 , Figure 6 and Figure 7As shown, a protrusion 14 is fixedly provided on the upper end of the clamp seat 11, and a concave block 15 is fixedly provided on the lower side of the round seat 12. The protruding part of the protrusion 14 is vertically slid into the concave part of the concave block 15. The concave block 15 and the protrusion 14 are fixed by screws so that a gap is left between the bottom surface of the concave part of the concave block 15 and the top surface of the protruding part of the protrusion 14. The adjusting column 33 is rotatably connected to the end of the connecting beam 31, and the rotating axis of the adjusting column 33 is parallel to the extension direction of the connecting column 2.

[0032] This structure is provided with an unloading structure that is convenient for the entire regulating device. By setting a connecting support structure of the protrusion 14 and the recessed block 15, after the screws are fixed, the connecting rod is supported and located at a fixed height of the lower steel structure 4. After the screws are removed, the protrusion 14 and the recessed block 15 are relatively displaced, the height of the round seat 12 is lowered, and the connecting rod can move downward. The downward moving connecting rod can drive the end of the connecting beam 31 to move downward, so that the adjusting column 33 of the obliquely offset hinged connecting beam 31 rotates inward due to the traction of the connecting rod, and changes from a vertical state to a skewed state. At this time, it is convenient to knock and unload the main support part 3. Preferably, the end of the top column 332 is a ball head structure, which can further ensure the supporting effect of the vertical state while facilitating subsequent unloading. By setting this unloading structure, after the upper steel structure 4 is fixed in place, the regulating device can be easily and quickly unloaded and removed, thereby improving engineering efficiency.

[0033] In a further solution, Figure 6 The connecting beam 31 includes a front tube 311, a middle tube 312 and a rear tube 313. The two ends of the middle tube 312 are respectively threadedly connected to the front tube 311 and the rear tube 313, and the threads at the two ends of the middle tube 312 have opposite rotation directions.

[0034] This connecting beam 31, through the two sections of the threaded connection structure with opposite rotation directions, can realize the extension and retraction of the two ends of the connecting beam 31 without rotation by rotating the middle cylinder 312, and the length is stable and does not shift. By setting the connecting beam 31 structure with adjustable length, the lateral position of the adjustment column 33 can be adjusted in multiple directions, making it more flexible and able to support the excellent force point between the upper and lower steel structures 4. Furthermore, the middle section of the middle cylinder 312 is also provided with a hexagonal protrusion 314 for easy tool clamping.

[0035] This invention also discloses a construction method of a complex steel structure 4 with upper support and lower hanging. The control device of the complex steel structure 4 with upper support and lower hanging has the following steps:

[0036] S1, starting from the bottom, build an upper support truss 5, and build multiple layers of lower steel structures 4 on the upper support truss 5 in sequence;

[0037] S2. Fix the clamping seats 11 at both ends and the middle of the multi-layer steel structure 4, and fix the convex block 14 and the concave block 15 between the clamping seat 11 and the round seat 12;

[0038] S3, pass the connecting column 2 through all the round seats 12, and continue to build the steel structure 4, which is supported by the transverse support beam 13;

[0039] S4. Insert the U-shaped buckle 32 of the connecting beam 31 into the connecting column 2, adjust the length of the connecting beam 31 and the length of the adjusting column 33, so that the adjusting column 33 is supported on the surface of the upper and lower steel structures 4. The two adjusting columns 33 need to be in a vertical state, and the connecting beam 31 is in a horizontal state. Install several main support parts 3 to make the upper steel structure 4 reach the set position;

[0040] S5, continue to build the upper multi-layer steel structure 4 in sequence, and build the lower hanging truss 6 on the upper steel structure 4;

[0041] S6. Remove the screws connecting the protrusion 14 and the recess 15, move the connecting column 2 downward, and disassemble the main supporting parts 3 and the pre-support seat 1.

[0042] This construction method is suitable for an integral construction building with an upper supporting steel structure 4 and a lower hanging steel structure 4. Since the lower hanging construction of the lower hanging steel structure 4 is difficult, the upper supporting steel structure 4 is installed first, and a temporary supporting regulating device is added. After all the steel structures 4 are installed, the regulating device is removed to complete the installation of the entire steel structure 4. This method has high safety and construction efficiency.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
