[0001] The present application relates to the field of shear wall internode column structure, and in particular to a steel formwork concrete combined cross-shaped internode column. Background Art

[0002] Steel formwork concrete structure is a combination of steel and concrete structure formed by pouring concrete inside with steel structural members as templates. Compared with traditional concrete buildings, steel formwork concrete composite structures can be factory-produced, integrated, standardized and digitally modeled. Steel formwork beam and column structures are more common structures in steel formwork concrete composite structures. As important supporting components of buildings, their performance directly affects the cost and safety performance of buildings.

[0003] At present, steel formwork concrete composite shear wall is a relatively common structure in steel formwork concrete structure, and the internode column is a more important structural component of the shear wall. The shape of the internode column can be set to a straight line, L-shape or cross shape according to the position of the shear wall.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there is a defect that the construction process of the cross-shaped internode column is relatively complicated. Summary of the invention

When constructing the cross-shaped internode column in the shear wall, the prefabricated cross-shaped internode column is directly placed on the supporting surface, the closing plate is fixed on the supporting surface, and concrete is poured into the interior from the top openings of the central column and the four side columns. After the concrete solidifies, the final cross-shaped internode column is formed, which has good seismic performance, can withstand large lateral forces, and the construction process is simple and convenient.

[0009] Preferably, the center column includes four vertical plates, which are arranged in a square shape, connected end to end and welded together to form the center column, and the four side columns are respectively fixed on the four vertical plates.

One end of the locking screw extending out of the outer side of the central column passes through the through hole and is threadedly connected with a locking nut, and the locking nut abuts against the clamping block.

[0016] By adopting the above technical solution, when connecting two adjacent vertical plates, the two vertical plates are spliced ​​together, and then a locking screw is used to pass through the connection holes on the two vertical plates and then connected to the clamping block, and finally two locking nuts are used to be threadedly connected to the two ends of the locking screw. In the process of tightening the locking nuts, the clamping block will gradually be squeezed toward one side of the vertical plate. After the two locking nuts are fully tightened, the two vertical plates are clamped by the two clamping blocks at the same time, so that the oblique cut surfaces of the two vertical plates are abutted together, completing the splicing function of the two vertical plates; at the same time, the relative position relationship of the two adjacent vertical plates can be adjusted by adjusting the tightness of the locking nuts to ensure the verticality of the two adjacent vertical plates.

[0028] By adopting the above technical solution, it is convenient for workers to use tools such as wrenches to twist the connecting sleeve to make it rotate, which makes it easier for workers to rotate the connecting sleeve.

[0051] The implementation principle of Example 1 of the present application is: first, four vertical plates 11 are welded to each other to form a central column 1, and then the end plate 21 and the two side plates 22 are welded to form side columns 2, and then the four side columns 2 are welded to the corresponding four vertical plates 11, and finally the bottom plate 31 is welded to the bottom end of the central column 1, and the side plate 32 is welded to the bottom end of the side column 2, so as to complete the prefabrication of the cross-shaped internode column; when installing the cross-shaped internode column, the prefabricated cross-shaped internode column is directly transported to the designated position, and after the bottom of the internode column is fixed, concrete is poured into the central column 1 and the four side columns 2 through the top opening of the central column 1 and the top opening of the side column 2. After the concrete solidifies, a cross-shaped internode column composed of a steel plate and concrete can be formed; the construction process is simple and convenient, which can not only ensure the seismic performance and lateral force resistance performance of the cross-shaped internode column, but also make the construction process simple and convenient.

[0059] The implementation principle of Example 3 is as follows: when welding two adjacent vertical plates 11, all the fixing blocks 124 are first installed on one of the vertical plates 11, and then the other vertical plate 11 is directly connected to multiple fixing blocks 124, so that the two right-angled side edges of the fixing blocks 124 are tightly fitted with the two vertical plates 11, thereby ensuring the verticality between the two adjacent vertical plates 11; at the same time, the relative position of the two vertical plates 11 can also be adjusted by adjusting the tightness of the fixing nuts 126.

[0060] In addition, before welding, the side plate 22 and the end plate 21 may also be connected together using the first connecting portion in the above-mentioned embodiment 2 or embodiment 3, which will not be described in detail here.

[0066] After the positions of the two connecting plates 233 are fixed, the connecting sleeve 2321 is rotated, and the connecting sleeve 2321 drives the two threaded sleeves 2323 to rotate synchronously, so that the two adjusting screws 2322 move at the same time; since the threads of the two adjusting screws 2322 have opposite rotation directions, the moving directions of the two adjusting screws 2322 are opposite, thereby realizing the function of adjusting the distance between the two connecting rods 231.

[0067] Reference Figure 8 A plurality of flat sections are also provided on the outer side wall of the connecting sleeve 2321 , so that workers can use tools such as wrenches to clamp the connecting sleeve 2321 for rotation, thereby saving labor when the workers rotate the connecting sleeve 2321 .

[0068] The implementation principle of Example 4 is as follows: after the four vertical plates 11 are spliced ​​together to form the central column 1 and the four side columns 2 are welded, the side plates 22 are welded to the corresponding vertical plates 11; before the side plates 22 are welded to the vertical plates 11, the positions of the side plates 22 and the vertical plates 11 are first aligned, and then the two connecting plates 233 are respectively welded to the side plates 22 and the vertical plates 11, and then the connecting sleeve 2321 is rotated by twisting it through the flat cut surface on the connecting sleeve 2321 using a wrench or other tool, and the positional relationship between the side plates 22 and the vertical plates 11 is fine-tuned by adjusting the spacing between the two connecting rods 231, and after ensuring that the side plates 22 are perpendicular to the vertical plates 11, the connection between the side plates 22 and the vertical plates 11 is spot-welded, and finally all the connection between the side plates 22 and the vertical plates 11 is fully welded, so that the four side columns 2 are welded to the central column 1.
