[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] See Figure 1 The present invention provides a steel tube bundle assembly structure and a method for manufacturing the same, which are used to address the problem of numerous weld seams and high welding difficulty in existing steel tube bundle assembly structures. The steel tube bundle assembly structure of the present invention uses a mortise and tenon joint structure to connect the stiffening plate to the outer steel plate. Wedge blocks are evenly spaced vertically at regular intervals based on the required force. The wedge blocks are only installed on the outer side. The wedge blocks are inserted into the slits of the stiffening plate on the outer side and then hammered into the inner side of the stiffening plate with a tool. The wedge blocks are then welded to the stiffening plate on the outside, completing the installation of the steel tube bundle assembly structure. The advantages of this structure and method are that the amount of welding is greatly reduced, the outer steel plate is not easily deformed, the construction speed is fast, the precision is high, and the difficulty is low. The steel tube bundle assembly structure of the present invention and its method for manufacturing are described below with reference to the accompanying drawings.

[0033] See Figure 1 , showing a transverse cross-sectional view of the steel tube bundle assembly structure of the present invention. Figure 2 , showing Figure 1 A partial enlarged diagram of point A in the middle. Figure 3 , showing the side view of the steel tube bundle combined structure of the present invention. Figures 1 to 3 , the steel tube bundle combination structure of the present invention is described.

[0034] like Figures 1 to 3 As shown, the steel tube bundle assembly structure 20 of the present invention includes an outer steel plate 21, a stiffening plate 22 and a wedge block 24. There are two outer steel plates 21, which are arranged opposite to each other. A plurality of tapered holes 211 are opened on the outer steel plates 21 at intervals; the stiffening plate 22 is supported on the inner side of the two outer steel plates 21, and the end side of the stiffening plate 22 is provided with a protrusion 221 corresponding to the tapered hole 211. Figure 5 As shown, both ends of the stiffening plate 22 are provided with a plurality of protrusions 221, and the setting position of the protrusions 221 corresponds to the setting position of the tapered holes 211. When installing the stiffening plate 22, the protrusions 221 are inserted into the corresponding tapered holes 211. Figure 6 and Figure 7As shown, a slit 222 is provided on the protrusion 221; the wedge block 24 is inserted into the protrusion 221 from the slit 222 on the protrusion 221, and the wedge block 24 props up the protrusion 221 so that the protrusion 221 is tightly attached to the hole wall of the tapered hole 221, thereby utilizing the wedge block 24 to realize the connection between the stiffening plate 22 and the outer steel plate 21.

[0035] The steel tube bundle structure 20 of the present invention includes multiple stiffening plates 22 spaced apart along the length of the outer steel plates 21. These plates 22 separate the inner sides of the two outer steel plates 21 to form multiple enclosed spaces. These enclosed spaces are used for pouring concrete during subsequent construction. The steel tube bundle structure 20 of the present invention can serve as a shear wall in a building. End seals 23 are provided at the ends of the two outer steel plates 21 of the steel tube bundle structure 20. These end seals 23 are welded to the ends of the two outer steel plates 21 using conventional welds. Preferably, the end seals 23 are square tubes.

[0036] In a specific embodiment of the present invention, Figure 2 As shown, after the wedge block 24 is inserted into the protrusion 221, the wedge block 24 is welded to the protrusion 221. The welding operation can be performed on the outside of the outer steel plate 21, and the connection between the wedge block 24 and the protrusion 221 is welded using a weld seam, so that the wedge block 24 and the protrusion 221 are fixed together, thereby strengthening the connection strength between the stiffening plate 22 and the outer steel plate 21.

[0037] The size of the protrusion 221 is much smaller than the length of the end side of the stiffening plate 22, so welding the protrusion and the wedge block can greatly reduce the welding amount, and the welding operation position is between the protrusion and the wedge block, which can avoid deformation of the outer steel plate, thereby improving both the processing speed and the processing accuracy.

[0038] In a specific embodiment of the present invention, Figure 2 and Figure 7 As shown, the depth of the slit 222 on the protrusion 221 is consistent with the depth of the tapered hole 211. When the wedge block 24 is completely driven into the protrusion 221, the side of the protrusion 221 is in contact with the hole wall of the tapered hole 211, so that the stiffening plate 22 is firmly connected to the outer steel plate 21 and is not easy to separate.

[0039] In a specific embodiment of the present invention, Figure 4 and Figure 7 As shown, the opening size of the tapered hole 211 near the outer side of the outer steel plate 21 is larger than the opening size near the inner side of the outer steel plate 21. Therefore, after the wedge block 24 is inserted into the protrusion 221, the protrusion 221 is not easy to fall out of the tapered hole 221.

[0040] In a specific embodiment of the present invention, Figure 2 and Figure 7As shown, the outer contour of the wedge block 24 is triangular.

[0041] Further, combined with Figure 3 As shown, the length of the wedge block 24 is smaller than the length of the protrusion 221 .

[0042] In a specific embodiment of the present invention, the arrangement position of the tapered hole 211 is consistent with the arrangement position of the stiffening plate 22 .

[0043] In a specific embodiment of the present invention, there are multiple stiffening plates 22 .

[0044] In a specific embodiment of the present invention, the slit 222 of the protrusion 221 on the stiffening plate 22 extends inward from the outer end surface of the protrusion 221, and the width of the slit 222 is 1.5 mm to 3 mm. Preferably, the width of the slit 222 is 2 mm.

[0045] The present invention also provides a method for manufacturing a steel tube bundle combined structure, which is described below.

[0046] The method for manufacturing the steel tube bundle assembly structure of the present invention comprises the following steps:

[0047] like Figure 4 As shown, a pair of outer steel plates 21 are provided, and a plurality of tapered holes 211 are formed on the outer steel plates 21 at intervals;

[0048] like Figure 5 As shown, a stiffening plate 22 is provided, and a plurality of protrusions 221 are provided on the end side of the stiffening plate 22. Figure 6 and Figure 7 As shown, a slit 222 is formed by cutting on the protrusion 221;

[0049] Combine Figure 1 As shown, a pair of outer steel plates 21 are arranged opposite to each other, and a stiffening plate 22 is supported between the two outer steel plates 21, so that the protrusions 221 on the stiffening plate 22 are placed in the corresponding tapered holes 211;

[0050] Combine Figure 7 and Figure 2 As shown, a wedge block 24 is provided, and the wedge block 24 is driven into the protrusion 221 from the slit 222 of the protrusion 221, and the protrusion 221 is propped open by the wedge block 24 so that the protrusion 221 is tightly attached to the wall of the tapered hole 211;

[0051] The protrusion 221 and the wedge block 24 are welded together, and after the stiffening plates are connected, a steel tube bundle assembly structure is manufactured.

[0052] In a specific embodiment of the present invention, when the slits are cut on the bump, the cutting is performed inward from the middle of the bump, and the width of the slit is preferably 2 mm.

[0053] In a specific embodiment of the present invention, the opening size of the tapered hole opened on the outer steel plate at the outer surface is larger than the opening size at the inner surface, so that after the protrusion is supported by the wedge block, the protrusion is not easy to fall out of the tapered hole, thereby realizing the connection between the stiffening plate and the outer steel plate.

[0054] The wedge block can be hammered into the convex block and the wedge block and the convex block can be welded on the outside of the outer steel plate. The operation is simple and convenient. There are multiple convex blocks and tapered holes. Compared with the full-length welding operation, the welding amount is small and the processing speed is fast.

[0055] After the multiple stiffening plates are connected to the outer steel plates, two end seals are provided at the ends of the outer steel plates, and the ends of the two outer steel plates are sealed by the end seals, thereby forming a steel tube bundle combined structure.

[0056] The steel tube bundle combination structure of the present invention is used for assembled steel structure houses. The mortise and tenon connection method is adopted to greatly reduce the welding amount of the steel tube bundle combination structure, the outer steel plate is not easily deformed, the construction speed is fast, the construction accuracy is high, it has good economic benefits, saves public resources, and improves safety.

[0057] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
